Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a seepage prevention device for post-pouring strips of composite slabs. Background Technology

[0002] Currently, prefabricated buildings are increasingly common in the construction industry, and composite slabs are one such component. Composite slabs are prefabricated monolithic floor slabs composed of precast slabs and cast-in-place concrete layers. Post-cast strips are concrete strips left at appropriate locations in the foundation slab, walls, and beams during construction to prevent harmful cracks that may occur in cast-in-place reinforced concrete structures due to uneven shrinkage or settlement, as required by design specifications.

[0003] During the actual construction process, the composite slab at the post-pouring strip is prone to floating and displacement during concrete pouring, which may cause it to fail to meet the design requirements, change the structure's load-bearing capacity, form quality defects, and increase the workload of workers in the process of correction; at the same time, it greatly reduces its construction efficiency, and some may be unable to be reset, which brings great management difficulties and corresponding quality risks to daily production.

[0004] Therefore, to solve the above problems, a seepage prevention device for the post-pouring strip of composite slabs is needed, which can meet the requirements of anti-buoyancy and anti-displacement functions and play a fixing role during the installation and pouring of composite slabs. Utility Model Content

[0005] In view of this, the purpose of this utility model is to overcome the defects in the prior art and provide a seepage prevention device for the post-pouring strip of composite slabs, which can meet the requirements of anti-floating and anti-displacement functions and play a fixing effect during the installation and pouring of composite slabs.

[0006] The present invention relates to a leak-proof device for post-cast strips of composite slabs, comprising an upper clamping member disposed at the post-cast strip, a lower abutment member disposed at the bottom of a supporting template, and a screw assembly that penetrates the supporting template and connects the upper clamping member and the lower abutment member to form a tie structure. The upper clamping member comprises a horizontal bar segment having a first horizontal end and a second horizontal end that are laterally separated. When in use, the first horizontal end and the second horizontal end are respectively supported at the top edge of the adjacent composite slab.

[0007] Furthermore, the upper clamping member also includes a vertical rod section for connection with the screw assembly.

[0008] Furthermore, the vertical rod segment is located in the middle section of the horizontal rod segment and has a threaded portion, which is used for screwing into the screw assembly.

[0009] Furthermore, the first and second ends of the crossbar segment are respectively L-shaped in cross section, conforming to the top edge of the corresponding composite plate.

[0010] Furthermore, the screw assembly includes an adjusting block and a screw disposed at the bottom of the adjusting block. The upper part of the adjusting block is used to connect with the vertical rod section, and the lower part of the screw passes through a through hole disposed on the support template and is connected to the lower abutment.

[0011] Furthermore, the upper part of the adjusting block has a threaded hole and is screwed to the vertical rod section through the threaded hole, and the lower part of the adjusting block is welded and fixed to the screw rod.

[0012] Furthermore, the lower abutment includes a pad fitted on the screw and a wooden block set below the support template. A nut that is threadedly engaged with the screw is provided on the lower abutment, and the nut is used to lock the lower abutment onto the screw.

[0013] The beneficial effects of this utility model are as follows: The anti-seepage device for the post-pouring strip of the composite slab disclosed in this utility model can effectively prevent the composite slab from floating or shifting during the pouring process by setting an anti-seepage device with a tension structure between the supporting template and the composite slab at the post-pouring strip, ensuring that each composite slab meets the design requirements, reducing the difficulty of operation, improving the efficiency of operators, reducing quality risks, preventing grout leakage in the later stage, reducing the risk of grout leakage and grinding, and achieving the expected purpose.

[0019] As shown in the figure, this embodiment includes an upper clamping member 3 disposed at the post-pouring strip 2, a lower abutment member disposed at the bottom of the support template 5, and a screw rod 9 assembly that penetrates the support template 5 and connects the upper clamping member 3 and the lower abutment member to form a tie structure. The upper clamping member 3 includes a horizontal bar segment 301, which has a first horizontal end and a second horizontal end that are laterally separated. When in use, the first horizontal end and the second horizontal end are respectively supported at the top edge of the adjacent composite plate 1, that is... Figure 2 The composite plate 1 shown is located at the top edge of the post-pouring strip 2. The first and second horizontal ends of the upper clamping member 3 simultaneously vertically limit the composite plates 1 on both sides of the post-pouring strip 2. Together with the lower abutment member and screw 9 assembly, a tension structure is formed at the connection between the composite plate 11 and the supporting template 52, providing pre-tightening force between the composite plate 1 and the supporting template 5 at the post-pouring strip 2, ensuring a tight fit between them. Figure 1 As shown in the diagram, multiple anti-leakage devices are arranged longitudinally at the post-pouring strip 2 in this scheme, thereby ensuring that the composite slab 1 and the supporting template 5 can fit tightly together in the longitudinal direction of the overall post-pouring strip 2, avoiding grout leakage. The device structure can effectively prevent the composite slab 1 from floating or shifting during the pouring process, ensuring that each composite slab 1 meets the design requirements, reducing the difficulty of operation, improving the efficiency of operators, reducing quality risks, preventing grout leakage in the later stage, reducing the risk of grout leakage and grinding, and achieving the expected purpose.

[0020] In this embodiment, the upper clamping member 3 further includes a vertical rod section 302 for connecting with the screw 9 assembly; the vertical rod section 302 is disposed in the middle section of the horizontal rod section 301 and has a threaded portion, the threaded portion being used for screwing with the screw 9 assembly; combined with Figure 2 and Figure 3 As shown, the upper clamping member 3 has a T-shaped structure and can be formed by welding steel pipes or steel bars. The horizontal ends of the horizontal bar section 301 are welded and fixed with connecting structures, which contact the top rib on the composite plate 1 and form a vertical limit on the composite plate 1 through the connecting structures. The upper clamping member 3 is mainly connected and locked to the screw rod 9 assembly through the vertical bar section 302. Therefore, a threaded part is provided at the lower part of the vertical bar section 302, and the threaded part is screwed and locked to the screw rod 9 assembly.

[0021] In this embodiment, the first and second horizontal ends of the crossbar segment 301 are respectively in the shape of an "L" that conforms to the top edge of the corresponding composite plate 1 in the cross section. Compared with the support structure of the vertical plate type, the first and second horizontal ends in the shape of "L" also have the function of actively limiting the position of the composite plate 1, which can further suppress the floating and vibration of the composite plate 1. Especially when the anti-leakage device is used on a large scale, the composite plates 1 are connected to each other to form a whole, and the overall anti-floating ability and anti-vibration ability are better.

[0022] In this embodiment, the screw 9 assembly includes an adjusting block 8 and a screw 9 disposed at the bottom of the adjusting block 8. The upper part of the adjusting block 8 is used to connect with the vertical rod section 302, and the lower part of the screw 9 passes through a through hole provided on the support template 5 and connects with the lower abutment. The upper part of the adjusting block 8 has a threaded hole 801 and is screwed to the vertical rod section 302 through the threaded hole 801. The lower part of the adjusting block 8 is welded and fixed to the screw 9. Figure 3As shown, the upper part of the adjusting block 8 is used to connect with the vertical rod section 302. Therefore, the upper part of the adjusting block 8 is provided with a threaded hole 801 section, while the lower part of the adjusting block 8 is welded and fixed to the screw 9. In use, when the threaded part of the vertical rod section 302 of the clamping member extends into the threaded hole 801, the lower part of the screw 9 passes through the through hole provided on the support template 5 and connects with the lower abutment. Then, by rotating the adjusting block 8, the horizontal rod section 301 and the lower abutment can gradually clamp the support template 5 and the composite plate 1.

[0023] In this embodiment, the lower abutment includes a pad 10 sleeved on the screw 9 and a wooden block 6 disposed below the support template 5. A nut 11 threadedly engages with the screw 9 is disposed below the lower abutment, and the nut 11 is used to lock the lower abutment onto the screw 9; combined with Figure 1 As shown, the lower abutment is similar to one end of the pull rod 9 in the prior art. The lower abutment in this solution is mainly composed of a pad 10 sleeved on the screw 9 and a wooden block 6 set below the support template 5. Through this structure, a pull structure is formed with the crossbar section 301 on the clamping member, which can simultaneously apply pre-tightening force between the two overlapping plates 1 on the left and right sides and the support template 5, making the connection between the two tighter and the gap smaller.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
