Abstract
Description
Technical Field
[0001] This application relates to the field of architecture, and in particular to a temporary support structure under beams on both sides of a post-cast strip. Background Technology
[0002] In building construction, in order to prevent harmful cracks that may be caused by uneven temperature and shrinkage in cast-in-place reinforced concrete structures, according to relevant specifications, temporary construction joints should be left at appropriate locations in beams and slabs as post-pouring strips. This temporarily divides the structure into several parts. After the pre-pouring structure undergoes internal shrinkage, the concrete at the post-pouring strip is poured after a certain period of time to connect the various parts of the structure into a whole.
[0003] Existing post-cast strips typically use a large number of steel pipes for support during the casting process. However, after the post-cast strip has been cast, it is inconvenient to remove the steel pipes, which reduces work efficiency. Utility Model Content
[0004] To address the aforementioned issues, this application provides a temporary support structure under the beams on both sides of the post-cast strip.
[0005] The temporary support structure under the beams on both sides of the post-cast strip provided in this application adopts the following technical solution:
[0006] A temporary support structure under beams on both sides of a post-cast strip includes a beam bottom template and a base. The beam bottom template is provided with a support component for supporting the beam bottom template, and the base is provided with an adjustment component for adjusting the support height. The support component includes a casting pipe, with a first connecting flange fixedly connected to the top end of the casting pipe and a second connecting flange fixedly connected to the bottom end of the casting pipe. The top end of the casting pipe penetrates the beam bottom template. The first connecting flange is fixedly connected to the lower surface of the beam bottom template, and the second connecting flange is fixedly connected to the adjustment component.
[0007] By adopting the above technical solution, during use, the top of the injection molding pipe is first inserted through the bottom formwork of the beam, and the first connecting flange is fixed to the bottom of the bottom formwork. Then, the base is fixed on the concrete surface at the bottom of the injection molding pipe, and the injection molding pipe is fixed by connecting and fixing it with the second connecting flange through the adjusting component. When pouring the bottom formwork of the beam, the injection molding pipe is poured to form a concrete column to support the bottom formwork of the beam. When disassembling, the injection molding pipe is cut circumferentially, and then the concrete column is broken. This avoids the problem of inconvenience in removing the steel pipe after the post-pouring strip has been poured and formed, which would reduce work efficiency.
[0008] Preferably, multiple mounting plates are fixedly connected to the bottom of the side walls on both sides of the base, and the upper surface of each mounting plate is provided with mounting holes for fixing.
[0009] By adopting the above technical solution, the base can be easily fixed to the concrete surface with external bolts through the mounting plate and mounting holes, thus securing the base.
[0010] Preferably, the adjustment assembly includes a lifting plate slidably disposed inside the base, a support seat fixedly connected to the upper surface of the lifting plate, a second connecting flange fixedly connected to the support seat, and adjustment rods fixedly connected to four ends of the upper surface of the lifting plate, the top end of the adjustment rods passing through the base and threadedly connected to a limit block.
[0011] By adopting the above technical solution, after the injection molding pipe is fixed under the bottom template of the beam through the first connecting flange, the lifting plate is moved upward by pulling the support seat, bringing the support seat close to the bottom end of the injection molding pipe, so that the bottom end of the injection molding pipe is fixedly connected to the support seat through the second connecting flange. Then, the limiting block is rotated to make the limiting block abut against the base to prevent the adjusting rod from sliding down and to fix the lifting plate, which facilitates support at different heights.
[0012] Preferably, the end of the adjusting rod away from the lifting plate is fixedly connected with a stop block to prevent the limiting block from falling off.
[0013] By adopting the above technical solution, the movement distance of the limit block is limited by the stop block, which can prevent the limit block from falling off the adjusting rod and causing the limit block to be lost.
[0014] Preferably, the base has multiple vertically arranged positioning rods fixedly connected inside, and the lifting plate is sleeved on the multiple positioning rods and forms a sliding arrangement.
[0015] By adopting the above technical solution, the stability of the lifting plate can be improved by using the positioning rod, preventing the lifting plate from shaking.
[0016] Preferably, multiple equally spaced fixing rods are fixedly connected to the top of both side walls of the base. L-shaped pressure plates are provided on both sides of the top of the base. The L-shaped pressure plates are respectively sleeved on the multiple fixing rods. A fixing block is fixedly connected to the end of each fixing rod away from the base. A spring is sleeved on each fixing rod. The two ends of the spring are fixedly connected to the fixing block and the L-shaped pressure plate, respectively.
[0017] By adopting the above technical solution, after the limiting block abuts against the base, the L-shaped pressure plate is pushed by the spring to move on the fixed rod, so that the L-shaped pressure plate is above the limiting block and fits against the limiting block. This can prevent the limiting block from rotating and moving upward on the adjusting rod, causing the lifting plate to move downward, and making it impossible to support the injection molding pipe through the support seat.
[0018] In summary, this application includes at least one of the following beneficial technical effects:
[0019] 1. This application utilizes the cooperative arrangement of the injection molding pipe, the first connecting flange, and the second connecting flange. In use, the top of the injection molding pipe first penetrates the bottom formwork of the beam, fixing the first connecting flange to the bottom of the beam formwork. Then, the base is fixed to the concrete surface at the bottom of the injection molding pipe. The pipe is then fixed by connecting and fixing it to the second connecting flange via an adjusting assembly. During the pouring of the beam bottom formwork, the injection molding pipe is poured to form a concrete column that supports the beam bottom formwork. Disassembly is achieved by circumferentially cutting the injection molding pipe and then breaking the concrete column. This minimizes the inconvenience of removing the steel pipe after the post-pouring strip has been poured, thus reducing work efficiency.
[0020] 2. After fixing the injection molding pipe to the bottom template of the beam through the first connecting flange, the lifting plate is moved upward by pulling the support seat, bringing the support seat close to the bottom end of the injection molding pipe, so that the bottom end of the injection molding pipe is fixedly connected to the support seat through the second connecting flange. Then, the limit block is rotated to make the limit block abut against the base to prevent the adjusting rod from sliding down and to fix the lifting plate, so as to facilitate support at different heights.

[0026] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.
[0027] This application discloses a temporary support structure under the beams on both sides of the post-cast strip.
[0028] Reference Figure 1 , Figure 2 and Figure 3 A temporary support structure under the beams on both sides of the post-cast strip includes a beam bottom template 1 and a base 2. The beam bottom template 1 is provided with a support component for supporting the beam bottom template 1, and the base 2 is provided with an adjustment component for adjusting the support height. The support component includes a casting pipe 3, a first connecting flange 4, and a second connecting flange 5.
[0029] The injection molding pipe 3 is an FRP pipe, which is easy to cut. Plain concrete is poured inside the FRP pipe to facilitate the breaking of the concrete column. The first connecting flange 4 is fixedly connected to the top of the injection molding pipe 3, and the second connecting flange 5 is fixedly connected to the bottom of the injection molding pipe 3. The top of the injection molding pipe 3 passes through the bottom formwork 1 of the beam. The first connecting flange 4 is fixedly connected to the lower surface of the bottom formwork 1 of the beam, and the second connecting flange 5 is fixedly connected to the adjustment component.
[0030] Reference Figure 3 Multiple mounting plates 6 are fixedly connected to the bottom of the side walls on both sides of the base 2. The upper surface of the mounting plates 6 is provided with mounting holes 7 for fixing. Through the mounting plates 6 and mounting holes 7, the base 2 can be easily fixed to the concrete surface with external bolts to fix the base 2.
[0031] Reference Figure 1 , Figure 2 and Figure 3 The adjustment assembly includes a lifting plate 8 slidably disposed inside the base 2. A support seat 9 is fixedly connected to the upper surface of the lifting plate 8. A second connecting flange 5 is fixedly connected to the support seat 9. Adjusting rods 10 are fixedly connected to the four ends of the upper surface of the lifting plate 8. The top of the adjusting rod 10 passes through the base 2 and is threadedly connected to a limit block 11. After the injection molding pipe 3 is fixed under the bottom template 1 of the beam through the first connecting flange 4, the lifting plate 8 is moved upward by pulling the support seat 9, bringing the support seat 9 close to the bottom end of the injection molding pipe 3, so that the bottom end of the injection molding pipe 3 is fixedly connected to the support seat 9 through the second connecting flange 5. Then, the limit block 11 is rotated so that the limit block 11 abuts against the base 2 to prevent the adjusting rod 10 from sliding down and to fix the lifting plate 8, so as to facilitate support at different heights.
[0032] Reference Figure 3 The end of the adjusting rod 10 away from the lifting plate 8 is fixedly connected with a stop block 12 to prevent the limit block 11 from falling off. By limiting the movement distance of the limit block 11 by the stop block 12, the limit block 11 can be prevented from falling off the adjusting rod 10 and causing the limit block 11 to be lost.
[0033] Reference Figure 3 The base 2 has multiple vertically arranged positioning rods 13 fixedly connected inside. The lifting plate 8 is sleeved on the multiple positioning rods 13 and forms a sliding arrangement. The positioning rods 13 can improve the stability of the lifting plate 8 and prevent the lifting plate 8 from shaking.
[0034] Reference Figure 3 and Figure 4 Multiple equidistant fixing rods 14 are fixedly connected to the top of both side walls of the base 2. L-shaped pressure plates 15 are provided on both sides of the top of the base 2. The L-shaped pressure plates 15 are respectively sleeved on the multiple fixing rods 14. The end of the fixing rod 14 away from the base 2 is fixedly connected to a fixing block 16. A spring 17 is sleeved on the fixing rod 14. The two ends of the spring 17 are fixedly connected to the fixing block 16 and the L-shaped pressure plate 15 respectively. After the limiting block 11 abuts against the base 2, the spring 17 pushes the L-shaped pressure plate 15 to move on the fixing rod 14, so that the L-shaped pressure plate 15 is above the limiting block 11 and fits against the limiting block 11. This can prevent the limiting block 11 from rotating and moving upward on the adjusting rod 10, causing the lifting plate 8 to move downward, and the support seat 9 cannot support the injection molding pipe 3.
[0035] The implementation principle of the temporary support structure under the beams on both sides of the post-cast strip in this application embodiment is as follows: In use, firstly, the top end of the injection molding pipe 3 passes through the bottom template 1 of the beam, and the first connecting flange 4 is fixed to the bottom of the bottom template 1 of the beam. Then, the base 2 is fixed on the concrete surface at the bottom of the injection molding pipe 3. By pulling the support seat 9, the lifting plate 8 is moved upward, bringing the support seat 9 close to the bottom end of the injection molding pipe 3, so that the bottom end of the injection molding pipe 3 is fixedly connected to the support seat 9 through the second connecting flange 5. Then, the limiting block 11 is rotated so that the limiting block 11 abuts against the base 2 to prevent the adjusting rod 10 from sliding down, and the lifting plate 8 is fixed to support the injection molding pipe 3. When pouring the bottom template 1 of the beam, the injection molding pipe 3 is poured at the same time to form a concrete column to support the bottom template 1 of the beam. When disassembling, the injection molding pipe 3 is cut circumferentially, and then the concrete column is broken. This avoids the problem of inconvenience in removing the steel pipe after the post-cast strip is formed, which reduces work efficiency.
[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
