Abstract
Description
Technical Field
[0001] This utility model relates to the field of post-pouring strip construction technology, and in particular to a support device for post-pouring strip construction. Background Technology
[0002] Post-construction joints are temporary construction joints set up to prevent harmful cracks in cast-in-place reinforced concrete structures due to shrinkage or uneven settlement. They release restraint stress and use expansive concrete to fill the joints to counteract residual stress. After the post-construction joint is constructed, a support device is needed to prevent cracks in the reinforced concrete. However, existing support structures usually require workers to tie steel bars to form a support frame to support the post-construction joint, which is time-consuming and labor-intensive and affects the construction rhythm. At the same time, because the ground at the construction site is not flat, it is difficult to place the support structure horizontally, resulting in insufficient support for the reinforced concrete and easy cracking of the reinforced concrete. Utility Model Content
[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a support device for post-pouring strip construction.
[0004] To solve the above technical problems, this utility model provides the following technical solution: a support device for post-pouring strip construction, including a support frame, support components are provided on both sides of the support frame, the support components include storage slots opened on both sides of the support frame, a first rotating rod is rotatably connected between the two sides of the inner cavity of the storage slot, a support plate is fixedly connected to the outside of the first rotating rod, an extension slot is opened inside the support plate, a sliding groove is opened on both sides of the inner cavity of the extension slot, a slider is slidably connected inside the sliding groove, an extension plate is fixedly connected between the two sliders, a second rotating rod is fixedly connected to the bottom of the extension plate, and a base plate is rotatably connected to the side of the second rotating rod away from the extension plate.
[0005] As a preferred technical solution of this utility model, the support frame is provided with adjustment components on both sides. The adjustment components include threaded barrels provided on both sides of the support frame. A first threaded rod is threadedly connected inside the threaded barrel. A placement block is fixedly connected to the end of the first threaded rod away from the threaded barrel. A handle is fixedly connected to the end of the first threaded rod away from the placement block and close to the threaded barrel.
[0006] As a preferred technical solution of this utility model, the two sides of the placement block are provided with fixing components, and the fixing components include fixing grooves formed on both sides of the placement block and used in conjunction with the base plate.
[0007] As a preferred technical solution of this utility model, the surface of the fixing groove is threaded with a second threaded rod, and the end of the second threaded rod away from the bottom plate passes through the placement block and extends to the outside of the placement block.
[0008] As a preferred embodiment of this utility model, a rotating block is fixedly connected to one end of the second threaded rod extending outside the placement block, and the base plate has a threaded opening that cooperates with the second threaded rod.
[0009] Compared with the prior art, the beneficial effects that this utility model can achieve are: This utility model, through the arrangement of a support frame, support components, and fixing components, enables the support of reinforced concrete. By rotating the support plate, the extension plate and the base plate slide out of the extension groove. Then, the base plate is rotated and inserted into the fixing groove. Next, the second threaded rod is rotated to descend and screw into the threaded opening, thereby firmly locking the base plate. This process enables the base plate, support frame, extension plate, and support plate to form a stable triangular support structure, significantly enhancing the support frame's stability for reinforced concrete. At the same time, it eliminates the tedious steps of traditional manual binding of steel pipes, effectively improving construction efficiency.
[0010] This invention, through the setting of a support frame and adjustment components, allows for height adjustment of the support frame when the ground at the construction site is uneven. By turning the handle, the second threaded rod is driven to descend, which in turn drives the first threaded rod and the placement block to adjust their height. This ensures that the support frame remains level at all times, avoiding the risk of cracking of reinforced concrete due to insufficient support and guaranteeing construction quality and progress.

[0014] Example: This utility model provides, for example... Figure 1 , Figure 2 , Figure 3 and Figure 4 The diagram shows a support device for post-pouring strip construction, including a support frame 1. Support components 2 are provided on both sides of the support frame 1. Each support component 2 includes storage slots 21 on both sides of the support frame 1. A first rotating rod 22 is rotatably connected between the two sides of the inner cavity of the storage slot 21. A support plate 23 is fixedly connected to the outside of the first rotating rod 22. An extension slot 24 is provided inside the support plate 23. Sliding grooves 25 are provided on both sides of the inner cavity of the extension slot 24. A slider 26 is slidably connected inside the sliding groove 25. An extension plate 27 is fixedly connected between the two sliders 26. A second rotating rod 27 is fixedly connected to the bottom of the extension plate 27. The moving rod 28 and the second rotating rod 28 are rotatably connected to the base plate 29 on the side away from the extension plate 27. Fixing components 4 are provided on both sides of the placement block 33. The fixing components 4 include fixing grooves 41 opened on both sides of the placement block 33 and used to cooperate with the base plate 29. The surface of the fixing groove 41 is threadedly connected to the second threaded rod 42. The end of the second threaded rod 42 away from the base plate 29 passes through the placement block 33 and extends to the outside of the placement block 33. The end of the second threaded rod 42 extending to the outside of the placement block 33 is fixedly connected to the rotating block 43. The base plate 29 is provided with a threaded opening 44 that cooperates with the second threaded rod 42.
[0015] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, by rotating the first rotating rod 22, the support plate 23 is rotated out from the storage slot 21. Then, the extension plate 27 slides out from the extension slot 24 through the cooperation of the sliding groove 25 and the slider 26. Then, by rotating the second rotating rod 28, the base plate 29 is rotated to fit against the ground and inserted into the fixed slot 41. Then, the rotating block 43 is rotated to turn the second threaded rod 42 into the fixed slot 41. At the same time, the second threaded rod 42 is rotated into the threaded opening 44 to fix the base plate 29, so that the base plate 29, the support plate 23, the extension plate 27 and the support frame 1 form a triangular support.
[0016] refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, adjustment components 3 are provided on both sides of the support frame 1. The adjustment components 3 include threaded barrels 31 provided on both sides of the support frame 1. A first threaded rod 32 is threadedly connected inside the threaded barrel 31. A placement block 33 is fixedly connected to the end of the first threaded rod 32 away from the threaded barrel 31. A handle 34 is fixedly connected to the end of the first threaded rod 32 away from the placement block 33 and close to the threaded barrel 31.
[0017] refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the worker moves the support frame 1 to the position where support is needed, and then turns the handle 34 to make the first threaded rod 32 rotate and descend through the cooperation of the threaded barrel 31, so that the placement block 33 contacts the ground. Then, the first threaded rod 32 on the other side is turned to adjust the support frame 1 to a horizontal height and make the support frame 1 support the concrete reinforcement. When support is not needed, the first threaded rod 32 is rotated and raised through the threaded barrel 31 by turning the handle 34. When the first threaded rod 32 rises, it drives the placement block 33 to rise. When the placement block 33 rises, the support frame 1 cancels the support for the reinforced concrete.
[0018] Working principle: Before use: Refer to Figure 1 and Figure 2 As shown, the worker moves the support frame 1 to the position where support is needed, and then turns the handle 34 to make the first threaded rod 32 rotate and descend through its cooperation with the threaded barrel 31, so that the placement block 33 contacts the ground. Then, the worker turns the first threaded rod 32 on the other side to adjust the support frame 1 to a horizontal height and make the support frame 1 support the cement steel bars.
[0019] When using: Refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, by rotating the first rotating rod 22, the support plate 23 is rotated out from the storage slot 21. Then, the extension plate 27 slides out from the extension slot 24 through the cooperation of the sliding groove 25 and the slider 26. Then, by rotating the second rotating rod 28, the base plate 29 is rotated to fit against the ground and inserted into the fixed slot 41. Then, the rotating block 43 is rotated to turn the second threaded rod 42 into the fixed slot 41. At the same time, the second threaded rod 42 is rotated into the threaded opening 44 to fix the base plate 29, so that the base plate 29, the support plate 23, the extension plate 27 and the support frame 1 form a triangular support.
[0020] After use: Reference Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, when no support is needed, the second rotating rod 28 is rotated out of the threaded opening 44, so that the second rotating rod 28 is no longer fixed to the base plate 29. Then the base plate 29 is taken out from the fixing groove 41. Then, by rotating the second rotating rod 28, the base plate 29 and the extension plate 27 are made to form the same plane. Then, the base plate 29 and the extension plate 27 are put into the extension groove 24 through the cooperation of the sliding groove 25 and the slider 26. Then, by rotating the handle 34, the first threaded rod 32 is rotated and raised through the threaded barrel 31. When the first threaded rod 32 rises, it drives the placement block 33 to rise. When the placement block 33 rises, the support frame 1 no longer supports the reinforced concrete.
