The invention relates to a sealing device for sealing joints between structural units, in particular between adjacent concrete structures, with injection channel according to the restrictive part of paragraph 1. The invention also relates to a sealing device for sealing joints between adjacent concrete structures, with injection channel according to the restrictive part 21. The invention also relates to a hollow profile strip for him.

In the brochure "Dichte Bauwerke "Die dichte Arbeitsfuge mit dem COMBIject Quellband-Injektionsschlauch-System ["sealed"design: sealed constructive connection with COMBIject swelling band/injection tube system] described sealing device with a housing having an injection channel, and the body is made of plastic and the side is covering the transverse part, as a result of this cross section set at an angle, forming a cavity that is open at the bottom and has a space formed under the lateral part. The hole in the tubular enclosure is injection channel, which is open and made a similar decreasing slit, the slit is closed on the connecting side through the open cellular foam strip that is installed in it. Swelling strip installed inside Polo the tee. So, for example, during Assembly of the foam strip and swelling band is not excluded from the sealing device, the sealing device is covered with a plastic mesh. The disadvantage is that the swelling band swells so that it can close the gap, pressing the slit and cell foam strip so that in the end, the injection passage of material out of the injection channel, at least very difficult and the injection channel thus becomes incapable of functioning. This sealing device leads to very high costs of production, because the individual parts of the sealing device from materials of size up to one meter it is difficult to combine together and, in particular, the assembled sealing device also falls apart easily, if it is not covered with a plastic mesh.

In the patent DE 4140616 A1, Figure 3, is disclosed injector tube, which has a tubular body made of plastic with a canal in it, and the output apertures which pass into the channel on the outer side of the housing. To flat cylindrical region of the connecting side of the housing adjacent swelling band, which is located along the entire length of the injector tube. Built-in channel and connecting the output channels connected to the output holes are filled with liquid is Tue or solid inert material, which can be moved out of the channel under the action of a jet of liquid or injection of a sealing material. Case and swelling strip enclosed in a woven or non-woven structure. This casing is made so that when the concrete wall is deformed, the concrete does not penetrate into the channel and the output channels. However, the casing material should be permeable for injection environment. It is, therefore, also applies to water and humidity, such as the cement liquid solution penetrating into the channel from the external side through the casing and through the output channels, which are blocked channels, with the result that the injection channel becomes incapable of functioning. A particular disadvantage is that the output channels are located at some distance from the connection side; this gives, thus, the ability to swell swelling band, which locks the ways in which the sealing material is removed from the output channels to connect, with the result that the sealing material from the output channels does not reach the voids compounds it contains. This injection pipe leads to very high costs of production, because the body tube and swelling of the strip must be carefully introduced into a narrow tube casing.

In the patent EP 0418699 A1, Figure 5, the disclosed sealing device is on, made of the transverse portions of the U-shaped profile, which is installed on the concrete surface and has an upper wall and two side walls. The free longitudinal edges of the side walls of the profile are placed on the concrete surface, with the result that the outlet for sealing material formed between the concrete surface and longitudinal edges. The profile below the bottom wall in the longitudinal direction is provided with a free end-to-end channel for the sealing material with the bottom wall, which is set approximately at half the height of the side walls and has a longitudinal slot of the outer sealing material. Below the bottom wall of the U-shaped space that has an open cellular plastic foam strip. The sealing medium is introduced primarily through channel and opening through the slot in the bottom wall in a plastic cell, end-to-end flow passage and thence passes under the longitudinal edges in the connection area between the first and second sections, which should be concreted together and sealed using a sealing medium. This sealing device has proved to be extremely effective.

In the patent EP 0804656, Figure 3, it is disclosed a sealing device for concrete connection, it germetezirujushie the device is made in the form of a connecting rail and has an injection channel, which is approximately similar to the channel according to the patent EP 0418699 A1 and has an output gap, which is blocked by a closed cellular foam strip, which is impervious to the injection of the material. If the injection of the material under pressure is introduced into the injection channel, the foam strip becomes a valve for injection of the material and it can go out in the connection region. When the pressure decreases, foam band, performing the function of the valve, again leaves the hole. This sealing device works really well.

The objective of the invention is to provide a sealing device which, in particular, satisfies the requirements of strength and ensures a reliable connection, and which is simple in manual and industrial Assembly and, in particular, reliably prevents escape of material passing through the channel.

The present invention is implemented by means of a sealing device according to the independent, paragraph 1, of the formula. The present invention is realized by the sealing device according to item 21 formula. Possible variants of the invention are characterized in the dependent claims.

According to the invention a sealing device for sealing joints between adjacent the concrete structures includes a housing with injection channel for injecting the injection material, the injection channel is provided on the connecting side, at least one outlet, for example, the output gap for injection of the material, and also has a tubular shutoff valve strip made of elastic material, which prevents the penetration of material from the outlet in the injection channel with connecting side shut-off valve strip is made in the form of a hollow profile strip. Shut-off valve, the band performed a structured cross-section and stretched given way under the pressure of the injection material in the exit slit injection channel so that eliminates the blocking action of the shut-off valve strip and the injection material can be moved outward from the housing with the channel in the lateral direction relative to the valve strip. The sealing device according to the invention is particularly reliable, because the shut-off valve strip ensures that the injection channel, in particular the outlet, remain free from contaminants, in particular swellable material which may cause blockage. Since the shut-off valve strip is made in the form of a hollow profile strip, it makes possible the elimination of the blocking activity even at relatively low pressure injection channel. Hollow prof is supplemented flax stripe, that is, the tubular shutoff valve strip is compressible, since the walls of the hollow profile strip of pliable, they can move inside the cavity.

In the particular case of the invention, a housing with a channel contains the base of the channel to accommodate the shut-off valve strip, in particular a hollow profile strip. The injection channel is connected to the base of the channel through the outlet, such as the output gap. Hollow profile strip can be placed particularly simply and quickly at the base of the channel and held there press fit, so that in the process of assembling the sealing device, it will not fall out from the base of the channel. Shut-off valve strip respectively protrudes from the base of the channel, and when it is placed on the concrete surface, is compressed to some extent, defined by the base.

Hollow profile strip has, for example, a narrow wall and/or the longitudinal edges, which rest against the connecting wall of the channel base and ensure press-fit of the hollow profile strip in the base of the channel.

Hollow profile strip has, for example, at least two oblique longitudinal walls that are located between the bottom wall and the top wall and each of which has an area of inflection, which, after compression, forms a desired location of the bend. the ve mutually opposite curved walls of the hollow profile strip, preferably, form side walls which support the base of the channel in the region of the bend of the connecting walls. The specified location of the inflection ensure controlled movement of the walls in flexure, especially that which contributes to the achievement of internal inflection, the education of a valve openings between the hollow profile strip and the walls of the base channel.

In the case of another variant of the invention, longitudinally spaced sealing edges are made on the side walls of the hollow profile strip between the point of inflection and the upper wall of the hollow profile strip, forming one whole with it, sealing the edges tightly interact with the connecting side walls of the base channel and the other form is actually a sealing face or narrow sealing surface in the longitudinal direction. As soon as the hollow profile strip is fixed in the base of the channel, the sealing edge pressed against the side walls of the base channel (press fit). Sealing edges guarantee a particularly high sealing action of the hollow profile strip against ingress of material from the outer side through the channels, through the labyrinth seal. Hollow profile strip has been cut open, can be compressed, hermeti youdim material, which is introduced into the injector through the channel and passes to the outside through, for example, through the hole so that the running press fits is permeable sealing material.

In addition, the hollow profile strip, preferably, is within at least two mutually opposite inner retaining wall, each of these walls has a similar place of inflection. The inner retaining wall is made preferably thinner than the side walls.

According to a preferred variant implementation of the invention, the upper wall of the hollow valve core strip has a concave, tube-like structure in the transverse cross-section and forms a tube, at least in the area of the outlet. When compressive loads sealing material of the top wall drops down and pulls the peripheral area to the center so that the end faces of the base of the channel and sealing the edges between the hollow valve core strip and the side walls of the base channel become permeable insulating material.

The invention also relates to a sealing device for sealing joints between adjacent concrete structures, in particular to the use of sealing devices described above, the cat is PoE includes a housing with injection channel for injecting a sealing material, injection channel having at least one outlet port for sealing material covering the band, which prevents the penetration of the material through an outlet opening in the injection channel, and swelling strip, the covering strip is made in one piece with swelling strip. Covering the band in this case, preferably, a shut-off valve strip.

The formation of the shut-off valve strip as a single whole with swelling band is especially appropriate, because the Assembly of the sealing device according to the invention is limited then the connection together of the two parts.

Swelling band placed essentially on the connecting side of the shut-off valve strip so that when it is not terminated, the operation performed on the channel. Relatively mild swelling band compensates for any possible small values of irregularities in the surface of the concrete connections and swells in places where no material is the result of the preliminary seal.

Swelling band respectively placed on the covering or closing of the valve strip outside of the housing with the channel.

According to a preferred variant of the invention swelling strip fixed to the bottom of the hollow profile wall, for example glued to it.

Swelling is olosa can be connected with covering or closing the valve strip at the first stage of production, this makes it possible connection strip with a channel in the second stage of production or under construction.

Swelling band is relatively flat, flexible, relatively soft strip, and preferably it is made transversely out of the channel with the formation of peripheral transverse parts. Peripheral transverse part, preferably located at an angle relative to the provided supporting connective region, as a consequence, a sort of curvature in the transverse direction. When the sealing device is applied to the concrete surface, the concrete support structure, the longitudinal peripheral part of the first come in contact with it. When the sealing device is pressed against a concrete support structure, for example, still being rigidly connected to it, the Central section of the swellable strip also comes in contact with the surface. After that, the free longitudinal edges of the side walls of the housing channel, respectively, are placed on the peripheral transverse parts, resulting sealing to eliminate penetration into the housing with the channel material or liquid, type of water or cement slurry.

An example of a variant embodiment of the invention is described in more detail hereinafter with reference the and drawings, showing:

Figure 1 - cross section of a sealing device according to the invention before Assembly;

Figure 2 is a cross section of a sealing device according to Figure 1 in assembled form.

The sealing device 1 includes a relatively rigid casing 2 channel, made of plastic, tubular hollow profile strip 3, which is placed in the channel of the housing 2 and forms a shut-off valve, and swelling of the strip 4.

Case 2 channel made for example from polyethylene, mainly high density (HDPE). The profile strip 3 is made, for example, of rubber, or polyethylene, mainly HDPE, or polyvinyl chloride (PVC), or polyurethane. Swelling strip 4 is made, for example, swelling of rubber or swelling of the plastic, especially swelling of the polyurethane.

Case 2 channel has a U-shaped cross-section, U-shaped channel is open in the direction of the connecting region, which should be sealed.

Case 2 channel has an upper wall 5 and two side walls 6, 7, side walls 6, 7 are of equal length, and their free ends form the longitudinal edges 8.

As one piece with the housing on the inner surface of the walls 6, 7 are formed in the longitudinal direction of the intermediate transverse side walls 9, 10, which are made, p is edocfile, at right angles to said walls, and leave the free longitudinal slot 11 between them.

The injection channel 12 is located above the intermediate transverse portions of the walls 9, 10; is located below the base of the channel 13, which is concave in the direction of the connecting region.

The cross-sectional shape of the housing 2 with the channel can also be arc-shaped, or trapezoidal, or polygonal, or the like, but must have a free longitudinal edges 8. Can also be done multiple injection channels 12. Instead of the longitudinal slit 11 can be executed hole or similar output channels.

The base of the channel 13 is mounted a hollow valve profiled strip 3, which is made of pliable, plastic, preferably vulcanized, elastomer materials.

Tubular hollow valve core band 3 has three through channel 3A, 3b, 3C, bottom wall 14, top wall 15, two side walls 16, 17 and inside, on each side, one retaining wall 18, 19 that are adjacent and performed with some clearance relative to the side wall 16 or 17. The walls 16, 18 and 17, 19 as shown in cross - section have the shape of arrows directed in each case to the outside, and is formed at the point of inflection 20 some angle. The purpose of the angle at the point of inflection 20 is Clare who apply later in the text.

Longitudinally spaced sealing edge 21 is fully formed on the outer side of the elevation angle of the bend 20 of the side walls 16, 17 in each case, the upper wall 15 and these sealing edges tightly sealed adjacent to the interior of the side walls 6, 7 in the base of the channel 13.

In place of the angle of the bend 20 of the side walls 16, 17 of the hollow valve profile strip 3 adjacent to the interior of the side walls 6, 7 of the housing 2 with the channel and, moreover, are held there in the area of the longitudinal edges 8.

Before sealing device has been described in pre-installation position (Figure 1), the bottom wall 14 and at least some sections of the walls 16, 18, 19, 17, which extend from the bottom wall 14 to bend 20, projected onto the base of the channel 13.

The top wall 15 of the hollow valve core band 3, respectively, is designed to be concave in cross section like the channel in the longitudinal direction. The bottom wall 14, opposite, has a substantially flat surface.

The transition region 25 between the top wall 15 and side walls 16, 17 rest in each case in the intermediate transverse side walls 9, 10.

According to one variant of the invention the valve strip 3 made in one piece with swelling strip 4. According to the illustrated version of the Britania swelling band 4 set the bottom wall 14 on the connecting side of the outer surface 22. Swelling strip 4, preferably mounted on the outer surface 22 of the bottom wall 14. For example, the valve strip 3 is associated with swelling of the strip 4 by pressing or vulcanization. Swelling strip 4 is made in the form of a flat strip and is wider than the bottom wall 14, as a result of this side are peripheral transverse part 24, which are located at an angle relative to the bearing surface 26.

If necessary, the protruding peripheral transverse part 24 swelling of the strip 4 can be made narrower or wider than illustrated in the figures embodiment, to ensure the device is sufficient swellable material, for example, depending on requirements. The width of the peripheral transverse portions 24 can be changed in the longitudinal direction, for example, to overlay a sealing device, mainly, place the fold on the concrete base 27.

Swelling strip 4 may have bumps or similar structural formations on the connecting side, so that eventually she will have special non-slip properties when applied to a concrete surface 26.

The thickness swelling of the strip 4, especially in the Central section 23, approximately corresponds to the thickness of the bottom wall 14, the wall 5, 6, 7, 9, 10, 14, 15, 16, 17 accordingly, the imp is tive approximately equal thickness.

The implementation of the overlay sealing device 1 in the operating position described hereinafter. For example, a connection is formed between the horizontal concrete base 27 and a vertical concrete wall (not illustrated). In the connection area between the concrete base and concrete wall, which must be installed after the sealing device 1 is mounted in operating position on the surface 26 of the concrete base 27, the peripheral longitudinal part 24 swelling strips 4 are based on concrete base 27. The sealing device 1 securely, for example, bonded or rigidly connected with a concrete base 27 by known means. In this case, swelling, band 4 close, essentially over the entire area of the surface opposite the surface 26 of the concrete base 27, and a hollow valve core bar 4 is pressed, preferably sealed to the longitudinal edges 8 of the housing 2 with the peripheral channel of the transverse portions 24 swelling of the strip 4. The sealing edge 21 and bend 20 of the side walls 16, 17 are pressed firmly and tightly to the side walls 6, 7, resulting finally runs forming the base of the channel, and this press fits does not allow any liquids to penetrate into the injection channel 12. The transition region 25 similarly tightly pressed to temporarily the output of the transversal parts of the walls 9, 10 (Figure 2).

The operation of the sealing device 1 in the collection is described hereinafter. Known liquid sealing material is injected under pressure in a known manner in the injection channel 12. The sealing material penetrates through the longitudinal slot 11 in the base of the channel 12, thus putting pressure on the concave upper wall 15. The top wall 15 bends under the pressure and moves in the connection direction and angle of the bend 20, bent inwards. The top wall 15 carries a sealing edge 21 and the sidewalls 16, 17, including the angle of the bend 20 in the inner direction, so in the end, the sealing action is removed, the insulating material may be inserted between the side walls 6, 7 and the profile strip 3, between the longitudinal edges 8 and swelling of the strip 4 and can penetrate into the voids of the connection.

The maximum pressure that the sealing material on the top wall 15 is lower than the pressure of the peripheral portions 25 of the upper wall 15 of the hollow valve core band 3 on the intermediate transverse side walls 9, 10, and lower than the pressure exerted on the side walls 6, 7 of the sealing edge 21 and seat angle bend 20, as a result of this sealing material under pressure is moved between the at peripheral portions 25 of the upper wall 15 and the intermediate transverse portions of the walls 9, 10, and from the base of the channel 13 through the rear part of the sealing edges 21 and angle of the bend 20 of the side walls 16, 17, through the longitudinal edges 8 of the side walls 6, 7 in the emptiness of the connection.

When water and/or moisture enter the connection, water comes in contact with the swellable strip 4. Swelling swelling material strip 4 extends and blocks further access water. Water and/or swelling material cannot penetrate into the base of the channel 13 or even in the injection channel 12, in particular because the longitudinal edges 8 of the side walls 6, 7 are fixed rigidly on the lower wall 14 of the hollow valve core band 3 and/or swelling on the strip 4. However, even if the water and/or swelling material penetrate into the base of the channel 13, the side walls 16, 17 of the hollow valve core band 3 interact with the side walls 6, 7 of the housing 2 with the channel and block the path in the injector channel 8. In particular, the side walls 16, 17 in place of the angle of the bend 20 and the sealing edge 21 is tightly pressed to the side walls 6, 7 of the housing 2 with the channel. This effectively prevents the penetration of water, moisture, liquid cement mortar or other contaminants in the injection channel 12.
