Joining device for building units

FIELD: building, particularly means for connecting building structures.

SUBSTANCE: joining device comprises several similarly sized members overlapped so that non-contacting parts are spaced apart. The members are connected with bolt. Connection parts of each member are formed as rimmed orifice having extension and depression with central aperture. Bend is made on one member side.

The invention relates to the construction and can be used to connect end-to-end building structures.

It is known connection of building elements, including braces, belts, fasenko interconnected by welding (Kan. "Metal structures". M, stroiizdat, 1978).

The disadvantage of this technical solution is the lack of unification of the gussets, the complexity of installation and nevozmojnosti dismantling of the structure.

It is also known connection of building elements, including collection sheet Fesenko in the form of an annular buttons (Bnettv. "Building on the CRO. transport". Moscow, 1955).

The disadvantage of this technical solution is mutual transmission of forces between the individual joined elements through the connecting elements, which reduces the rigidity of the node.

The closest to the essence and the achieved effect to the present invention is the connection of building elements containing superimposed on each part having recesses and protrusions, United clamping device (the Description of the patent No. 694080 M CL. 2 E 04 1/58 Connection building elements).

The disadvantage of this connection is the connection of only two elements, and raznozazornost the reverse of the contour of the projections and recesses eliminates the possibility of the activity of the compounds in the package several parts, and multiple coupling bolts when mounting makes the connection in position and eliminates the creation of end-to-end designs with rods in several ways, also increases the complexity of Assembly and disassembly.

The purpose of the invention is to reduce the complexity of Assembly and disassembly, the expansion of the scope through the creation of long-span structures bolted.

The goal is solved by the present invention. In connection building elements containing the interface and handling package on each other part having a counter-contours of the surfaces of identical shape and size included in each other, in the contact recesses and protrusions, United clamping device according to the invention the package is composed of parts with holes, framed in the form of skirts, the shape of which is formed parallel relief mask bottom surface details on the value of the thickness in the direction of the top surface, and the package between the surfaces of the bases of the protrusions, depressions skirts left a gap, and the clamping device is designed as a hollow bolt, the outer form of the head which matches the internal shape of the skirt. Skirts can be conical, spherical, or in the form of truncated pyramids.

In a preferred embodiment, the compounds of the skirt can be the is made conical, spherical or in the form of truncated pyramids, and the number of components connected in the package may be more than two, their longitudinal axis is placed fan-shaped and vzaimozavisimy from rotating relative to each other.

The connection of building elements, which contains the same size, superimposed on each other with a gap detail, interconnected by a bolt, the connecting portion of the part made in the form of framed skirt holes with a protrusion and an indentation in the middle of which there is a hole, and on one side part has a contour that avoids the weakening of the parts of the hole, to reduce the consumption of metal, the complexity of Assembly and disassembly, to simplify the design of the interface, to extend the possibility of creating fabric designs on bolted joints. The execution of the hollow bolt expands the scope of a connection as in greenhouses through it can be extended trellis, skipped wire lights for plants, skipped and fixed film fixed tie and other communications.

The claimed connection of building elements is different from the known, taken as a prototype, the fact that the package is composed of parts with holes, framed in the form of skirts, the shape of which is formed parallel relief mask bottom surface details on the value of thickness is etale towards the top surface, moreover, in the package between the surfaces of the bases of the protrusions-depressions skirts left a gap, and the clamping device is designed as a hollow bolt, the outer form of the head which corresponds to the internal shape of the skirt.

Comparable analysis of the claimed solution with the known leads to the conclusion that the proposed technical solution meets the criteria of the invention of "novelty."

Of patent and technical literature is not known connection of building elements, in which the package is merged projections included in the basin, causing the gap between the parts of the package, but excluding the gap between soprikasayutsya surfaces of the protrusions-depressions, which allows to obtain the above effect.

Thus, the proposed solution meets the criteria of the invention "inventive step".

The inventive solution can be used in construction for connection through building structures, it will reduce the complexity of installation and dismantling, to extend the scope by creating long-span structures bolted.

Thus, the proposed solution meets the criteria of the invention "industrial applicability″.

The invention is illustrated by drawings, where figure 1 shows the connection of 3 parts of building elements: on ih - section a-a in figure 1, figure 3 - construction element, one end of which the protrusion-recess in the form of a hollow cone, figure 4 - construction element, on both ends of the protrusion-recess in the form of a hollow cone.

Connection of building elements contains the same dimensions of the part 1, superimposed on each other with gaps (2) in recontacterai parts interconnected by a bolt 3 and having the limb 4 on one side. The connecting portion of the part made in the form of framed skirt holes with the projection 5 and the recess 6, in the middle of which there is a hole 7. The protrusions and recesses may be conical, spherical, or in the form of truncated pyramids and executed on one or two ends of the element. The bolt 3 is made with a cavity 8, (such as from a pipe) external shape of his head conforms to the shape of the inner recess of the skirt. The rod between the protrusions has a shape with a developed cross-section (area, channel, pipes and so on).

The present invention is implemented as follows. Construction details skirts overlap each other and are connected by a bolt. The number of connected components may be more than two, United in service, their longitudinal axis can be placed fan in vzaimovyazany from rotating relative to each other.

Proposed the e connection will allow you to avoid the weakening of the parts with a hole, to reduce the consumption of metal, the complexity of Assembly and disassembly, to simplify the design of the interface, to extend the possibility of creating fabric designs on bolted joints. The execution of the hollow bolt expands the scope of a connection, because through it can be extended trellis, skipped wire lights for plants, skipped and fixed film fixed communications and other communications.

1. The connection of structural elements, containing between superimposed on other items, made with a hole and having a counter-surfaces of the same shape and size, incoming into each other in the contact protrusions and recesses, and the clamping device, characterized in that the hole in the part located in the middle of the frame protrusion with the recess, the shape of which is formed parallel to the surface of the ledge on the value of the thickness at the side surface of the recess, the parts are connected in the package with the possibility of two or more, while between the surfaces of the bases of the projections and recesses left by the gap, the clamping device is designed as a hollow bolt, the outer form of the head which corresponds to the inner shape of the recess and the longitudinal axis of the joined parts can be placed fan-shaped and vzaimovyazany from rotating relative to each other.

2. With the unity according to claim 1, characterized in that the frame holes may be made conical, spherical, or in the form of truncated pyramids.
