Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a novel force transmission device for post-settlement pouring strips. Background Technology

[0002] A post-cast strip is a concrete strip left at the corresponding position of the foundation slab, wall, or beam in the construction process to prevent harmful cracks that may occur in the cast-in-place reinforced concrete structure due to uneven shrinkage or settlement. According to the design or construction specifications, the post-cast strip temporarily divides the structure into several parts. After the internal shrinkage of the component, the construction joint concrete is poured again after a certain period of time to connect the structure into a whole.

[0003] According to the search results, the announcement number CN212561623U, named "Reusable Post-Pouring Strip Replacement Force Transmission Device", includes two brackets, a force transmission beam and multiple high-strength bolts. Through research and analysis, it was found that although the installation is simple and can significantly speed up the construction progress, it still has the following disadvantages to a certain extent.

[0004] For example, the installation position of the force transmission beam in the above-mentioned post-cast strip force transmission device is fixed, which makes it inconvenient to adjust the installation position of the force transmission beam. In some complex structures, due to the special nature of the structural form and load distribution, the installation position of the force transmission beam needs to be flexibly adjusted, which makes it difficult for the force transmission device to adapt to the needs of different engineering conditions. In order to solve the above technical problems, it is necessary to design a new type of settlement post-cast strip force transmission device to solve the above problems. Utility Model Content

[0025] Please see Figure 1 There are several threaded holes 23, which are arranged at equal intervals. The first bolt 24 is threadedly connected to the threaded holes 23. By setting multiple threaded holes 23, the first bolt 24 can be connected to the threaded holes 23 at different positions, which facilitates the adjustment of the installation position of the slide 21 and the force transmission steel beam 22 and improves the installation flexibility of the force transmission steel beam 22.

[0026] Please see Figure 1 A mounting plate 25 is fixedly connected to the surface of the support rail 20. A second bolt 26 is connected through the top of the mounting plate 25. The bottom of the mounting plate 25 contacts the main beam 1.

[0028] Please see Figures 1-3 The top of the main beam 1 is provided with a positioning groove 4, and the bottom of the support rail 20 extends into the inner cavity of the positioning groove 4. By setting the positioning groove 4, it can be positioned and engaged with the bottom of the support rail 20, so that the support rail 20 is tightly connected to the main beam 1.

[0029] Please see Figures 1-3The support mechanism 3 includes a first connecting block 30, one side of which contacts the main beam 1. A second connecting block 31 is fixedly connected to the top of the first connecting block 30. A third bolt 32 is passed through the top of the second connecting block 31. A threaded pipe 33 is fixedly connected to the surface of the first connecting block 30. A threaded rod 34 is passed through the surface of the threaded pipe 33. A hexagonal block 35 is fixedly sleeved at the center of the surface of the threaded rod 34. By setting the first connecting block 30, the second connecting block 31, the third bolt 32, the threaded pipe 33, the threaded rod 34, and the hexagonal block 35, the two main beams 1 are supported and connected, and the main beams 1 are reinforced and supported. This can better ensure the coordinated work of the structures on both sides of the post-cast strip, enhance the overall integrity of the structure, reduce structural deformation and cracks caused by the construction of the post-cast strip, and improve the service life and durability of the building.

[0030] Please see Figure 3 A reinforcing tube 36 is fixedly sleeved on the surface of the threaded tube 33, and a first reinforcing block 37 is fixedly connected to the surface of the reinforcing tube 36.

The bottom of the second bolt 26 passes through the second connecting block 31 and extends into the inner cavity of the second embedded part 38. The second bolt 26 is threadedly connected to the second embedded part 38. By setting the second bolt 26 and the second embedded part 38, it is convenient to fix the second connecting block 31, and then fix the support mechanism 3, so that the support mechanism 3 and the main beam 1 are stably installed together.

By setting the reinforcing plates 310, the force transmission steel beam 22 is reinforced, thereby improving the stability of the force transmission steel beam 22.

[0033] In use, the bottom of the support rail 20 is inserted into the cavity of the positioning groove 4. The second bolt 26 passes through the mounting plate 25 and is threaded to the first embedded part 27 to fix the mounting plate 25 and the support rail 20. The slide 21 is fitted onto the surface of the support rail 20. The position of the force transmission steel beam 22 is adjusted by moving it back and forth. The first bolt 24 passes through the slide 21 and is connected to the threaded hole 23 to fix the slide 21 and the force transmission steel beam 22. The tool rotates the hexagonal block 35 to drive the threaded rod 34 to rotate. The threaded rod 34 is threaded to the threaded pipe 33 to move the threaded pipe 33 laterally. The threaded pipe 33 drives the first connecting block 30 to move, so that the first connecting block 30 fits against the main beam 1. The third bolt 32 passes through the second connecting block 31 and is threaded to the second embedded part 38 to fix the second connecting block 31. The post-pouring strip is installed between the two main beams 1 and concrete is poured.
