The invention relates to spotovi connections and can be used in hydraulic engineering to connect the piles during the construction of sea and river berths, as well as in civil and industrial construction.

Known sheet pile compound containing T-shaped sheet tabs and sheet grippers (sheet locks)made of angular profiles with the formation of the box-shaped profile in cross-section, in the internal cavity of each of the box-shaped profiles installed the rib welded thereto lateral edges (RU # 2081238, 1997).

The disadvantage sportowego connection is insufficient strength sportowego grip, made of angular profile, as well as a large number of welded joints.

Known sheet pile connection used in spotboy the wall of the tubular piles containing sheet grippers (sheet locks) and sheet tabs, made of rolling elements shaped cross-section, provided with a support section welded (fifth). In the specified well-known connection every sportowy ledge made with a comb round or oval cross-section, and each sportowy capture cross-section is made in the form of a cage with a mouth in the shape of comb sportowego ledge and covering it partially on the relative rotation and longitudinal movement (utility model RU # 106264, 2011, prototype)

The specified well-known sheet pile connection is much stronger than the previous, however, to manufacture rolling shaped profile cross section, which is made from sheet grippers in a known technical solution is complex and expensive imported equipment, which significantly increases the price of such sportowego connection.

The technical task of the present invention is to provide sportowego connections that do not have the disadvantages of the known sheet of compounds from the prior art, i.e. technological and budget.

The technical result is the possibility of production of rolling elements that are grips offer sportowego connection on standard national rental equipment, ensuring high strength of the connection.

The problem is solved due to the fact that in spontoon the connection involving made of rolled profiles sportowy ledge with a crest and sportowy capture containing the reference section welded and the clip from the mouth, the shape of the ridge sportowego ledge and covering it with a possibility of longitudinal movement of partial rotation, according to the invention sportowy grip is made of two rolling sections, each of which in cross section has the form of cu is ka, formed C-shaped section and paired with one of its edges with a straightforward plot, the said hooks facing concave sides of the C-shaped sections to each other with the formation of the cage for a comb sportowego lip and welded rectangular sections with each other directly or through an intermediate coupling element to provide a gap between the free edges of the C-shaped sections hooks.

Comb sportowego protrusion may be made round or oval in cross section and conforms to the shape of the mouth of the cage formed by the C-shaped sections of the profiles capture sportowego compounds according to the invention.

In spontoon connection according to the invention, the intermediate coupling element may be made rectangular in cross section.

It is also possible the performance sportowego compounds of the present invention, when in the capture of the intermediate connecting element is designed as a rolling profile of the T-shaped in cross-section, the cross-shelf which serves as the fifth weld.

Possible variant of the proposed sportowego connection, in which the mentioned straight line segment of the cross-section of one of the rolling grip is made greater than the length of ramalina the initial plot of the cross-section of another rolling profile and is used for welding to the construction product, i.e. to the pile.

In yet another embodiment, sportowego compounds of the present invention a straight line segment of each rolling profile sportowego capture can be performed partially unbent outward toward the convex side of the hook, i.e. outward relative to the axis of symmetry of the grip to increase bearing surface, increasing the stability of the grip on the pile and welding facilities.

In spontoon connection according to the invention, the capture is not an integer, i.e., not in a single piece, as in the prototype, and welded of the two rolled sections, has several advantages.

First of all, the proposed form of rolled profiles in the form of hooks with a plot of C-shaped cross-section, smoothly paired with almost rectilinear site, it is practically feasible to fabricate these profiles on the ordinary domestic rolling mills, which of course reduces their cost compared to the prototype. Plots of the cross-section of each of the welded rolled sections made smoothly mated, without sharp corners, making possible the emergence of stress concentrations that could result in reduced strength. On the strength of the takeover offer sportowego connection is not inferior to the prototype, but much cheaper, even taking into account the welding operation.

In the manufacture of the grip facing the mirror each other profiles are superimposed by straight sections and welded overlap directly between themselves or by welding from both sides to the intermediate connecting element. This guaranteed a gap necessary to ensure connection of the grip with tongue-and-groove ledge. This clearance may be increased due to the thickness specified intermediate coupling element, namely the part which is adjacent straight sections of welded rolled profiles.

If the proposed sportowego connection, when the welding of rolled sections made through an intermediate connecting element, it becomes possible before welding of profiles to each other due to selection of the wall thickness of the intermediate connecting element set between the free edges of the C-shaped sections, the gap of such size as is necessary to ensure the required degree of tightness of the connection in accordance with the properties of the soil. The smaller this gap, the denser adjacent the mouth of the clip to the flange, the denser and hermetic sheet pile connection that is set during construction on sandy and poor soils. During the construction of the hard and rocky ground clearance can be increased to is oblegcheniya institutions in the castle, what becomes possible when an intermediate coupling element. It should also be noted that due to the intermediate coupling element can be compensated error of welding.

In the case of performing the intermediate coupling element in the form of roll profile with T-shaped cross-section, relatively vertical portion of this profile is strictly for placing the above-mentioned gap, it abut and are welded straight lengths hook profiles, and perpendicular to this segment, part cross-sectional T-shaped connecting element plays the role of the toe of the weld. The presence of heel increases the bearing surface and the sustainability of capture, facilitates the mounting of the attachment on the pile and welding.

In spontoon the grip according to the invention, the free ends of straight portions profiles welded together (hooks) represent the reference section for welding to capture the joined building construction, mainly, to the piles tubular section.

The straight sections of the cross-section of the rolled sections, i.e. hooks, can be made shorter to provide greater rigidity and strength of the connection, or may be elongated to less durable and less bulky option Stroitel the th design.

In the embodiment, when a straight line segment of one of the hooks grip is made longer than the length of the straight section of the other of the hook, the strength of the grip is slightly lower, but its intensity is less. Such capture is applicable to less-loaded structures.

Run straight portions of the rolled sections partially bent outward relative to the axis of symmetry of capture, i.e. in the direction of the convex part of the C-shaped sections, as shown in figure 5, increases bearing surface capture, provides him with greater stability on the pile, increases the ease of welding.

The invention is illustrated by drawings, which depict:

figure 1 - sheet pile connection Assembly, the cross section;

figure 2 - the same, with short straight sections of both

profiles capture;

figure 3 - the same, with a short straight section of one of the rolling grip;

figure 4 - the same, with an intermediate connecting element is T-shaped cross-section;

figure 5 - the same, with convex ends of the straight portions of the profile.

Below are examples of specific implementation of the present invention, in which identical elements are denoted by the same positions.

Sheet pile connection according to the present invention includes sportowy istop 1 comb 2 and sportowy capture 3, made of two rolling sections 4 and 5, each of which has a cross section generally in the shape of a hook. In the cross section of the rolling profile 4 consists of a C-shaped section 6 and smoothly mated with one edge of the straight part 7, and rolling profile 5 consists of a C-shaped section 8 and paired with one edge of the straight part 9 (figure 1 and figure 2).

The free ends 10 and 11 of straight portions 7 and 9 are cross-sectional profiles 4, 5 (hooks) made rounded at a radius R in accordance with the technology of the car. The ends 10 and 11 of straight portions 7 and 9 are welded between the hooks 4, 5 form the reference area used for welding capture to one of the connected products, in this case to the pile.

Shown in figure 2 embodiment, the capture straight sections 7 and 9 of the profiles 4 and 5 are the minimum necessary from the standpoint of ease of welding the length of the straight part of the cross section.

In the manufacture sportowego capture according to the invention, install two rolled sections 4 and 5 mirror concave sides toward each other, when this is brought into contact them straight sections and weld between a lap. This C-shaped sections 6 and 8 form the ferrule 12 with the mouth And for a crest 2 sportowego ledge 1,and between the free edges of the C-shaped sections 6 and 8 of the hooks 4 and 5, a gap B. The gap B can be increased by installing an intermediate connecting element with a rectangular cross-section (not shown), or the intermediate connecting element 13, shown in figure 4, with a T-shaped cross-section.

Portion of the grip, limited areas 6 and 8, is a clip capture, the inner cavity of which, the so-called mouth And capture repeats the shape of the crest 2 sportowego hanging 1 with a slight gap, providing the possibility of partial rotation and longitudinal movement in the United lock grip 3 and the protrusion 1. Due to the form of the C-shaped sections mouth And can be practically round, or elongated, i.e. an oval cross-section depending on the cross-sectional shape of the ridge 2.

In the embodiment of the invention, depicted in figure 4, the hooks are welded to each other through an intermediate connecting element 13 made of T-shaped in cross section and consisting of mutually perpendicular sections: section 15, to which is welded profiles 4, 5, i.e. the wall of the letters T and section 16, i.e. the cross-shelf letter T in the role of a heel welded capture 3 to the pile.

In the embodiment depicted in figure 5, the profiles 4, 5 are bent parts 17 and 18 of the straight portions 7, 9. So their ends 10, 11 and, therefore, svarny the seams, which grip is welded to the pile, separated by some distance along the width. Capture in this version more stable in comparison with the embodiment shown in figure 1.

As mentioned above, the advantages of the proposed sportowego connection is its adaptability and significantly lower price compared to the prototype at a comparable strength. Also a big advantage is the ability to expose the gap in the capture of any size you want depending on the geological conditions of the specific construction of the object with greater or lesser integrity of the structure.
