Abstract
Description
Technical Field
[0001] The present invention relates to the field of building construction, and particularly to a formwork reinforcement structure for a reaction wall. Background Art
[0002] As a key load-bearing member in a building structure laboratory, the formwork installation of a reaction wall needs to meet the construction requirements of high precision and large load. The traditional reinforcement method mostly uses a combined support system of steel pipes and fasteners and wooden squares, which has problems such as insufficient adjustment accuracy and significant cumulative errors at multiple nodes. Especially when facing reaction walls with large cross-sections (thickness ≥ 1800 mm) and large spans (width ≥ 8000 mm), template displacement or local formwork bulging is likely to occur. In the prior art, welding fixation is often used for steel pipe positioning, resulting in low reuse rate and inability to adapt to different pipe diameter requirements. And the connection of formwork columns mostly relies on manual positioning, making it difficult to achieve three-dimensional fine adjustment. Although there are individual modular reinforcement devices using screw drive, they lack a linkage adjustment mechanism and a self-locking stability device, and are prone to structural rebound under dynamic loads.
[0003] Therefore, in view of the above problems, a formwork reinforcement structure for a reaction wall is now developed. Summary of the Invention

[0009] Optionally, it further includes a second mounting bracket. Two symmetrically arranged second mounting brackets are mounted on the mounting bracket. A second pin is slidably connected to the right part of the second mounting bracket. The second mounting bracket is used to strengthen the connection between the device and the formwork column of the reaction wall.
[0010] Optionally, it further includes magnetic components. The conical part is provided with magnetic components corresponding to the number of the lifting blocks. The magnetic components are used to adsorb and stabilize the lifting blocks in the non-expanded state.
[0011] Optionally, it further includes a protective frame. The protective frame is arranged on the right part of the mounting bracket.

[0015] By adopting the above technical solutions, the present invention has the following advantages: 1. The present invention realizes the synchronous movement of the contact columns through a double lead screw linkage system. Cooperating with the adjusting screw rod with a conical part, the contact pressure between the lifting blocks and the inner wall of the steel pipe can be accurately controlled, forming a radial self-locking effect. The hollow screw rod structure is convenient for inserting the connecting rod to realize cross-column interlocking. The pre-adsorption function of the magnetic components on the lifting blocks effectively avoids the structure shaking in the non-working state and ensures the safety during transportation.
[0016] 2. The present invention significantly improves the construction efficiency through a modular assembly system. The quick plug-in mechanism of the first mounting bracket and the second pin shortens the reinforcement time of a single column. The sprocket and chain system embedded in the protective frame ensures the synchronous accuracy of the double lead screws and avoids the formwork distortion caused by asynchronous movement.

[0028] A reaction wall formwork reinforcement structure, as Figures 1-9As shown in the figure, it includes an installation bracket 1. A moving block 2 is slidably arranged on the installation bracket 1. A first lead screw 3 is rotatably connected to the installation bracket 1. The first lead screw 3 is threadedly connected to the moving block 2. A first mounting bracket 4 is rotatably connected to the moving block 2. The first mounting bracket 4 is used to connect with the formwork column of the reaction wall. A first pin 5 is slidably connected between the first mounting bracket 4 and the moving block 2. The first pin 5 is used to lock the first mounting bracket 4. Two second lead screws 8 that are symmetrically arranged front and back are rotatably connected to the installation bracket 1. Mounting plates 7 are threadedly connected to both of the second lead screws 8. A contact column 6 is connected between the mounting plates 7 by bolts. The contact column 6 is used to press and limit the steel pipe inside the reaction wall. A rotating disc 9 is connected to the right side of each of the second lead screws 8. A power-assisted handle is provided on each of the rotating discs 9. An adjusting screw 10 is threadedly connected inside the contact column 6. The adjusting screw 10 is of a hollow structure. A conical part 12 is arranged at the left end of the adjusting screw 10. A lifting clamping block 11 is slidably connected to the left part of the contact column 6. The lifting clamping block 11 is in contact connection with the conical part 12. The lower part of the lifting clamping block 11 is of an arc surface structure. The lifting clamping block 11 is used to fit and support the inner wall of the plastic steel pipe inside the reaction wall. A fixed sleeve rod 14 is slidably connected inside the conical part 12. A positioning disc is provided on the fixed sleeve rod 14. The positioning disc can be slidably clamped with the conical part 12. A connecting rod 13 is slidably connected inside the fixed sleeve rod 14. The connecting rod 13 is connected to the adjusting screw 10 in a penetrating manner. The connecting rod 13 is used to position the adjusting screw 10 on the other side. Two second mounting brackets 15 that are symmetrically arranged front and back are installed on the installation bracket 1. A second pin 16 is slidably connected to the right part of the second mounting bracket 15. The second mounting bracket 15 is used to strengthen the connection between the device and the formwork column of the reaction wall. Magnetic parts 17 corresponding to the number of the lifting clamping blocks 11 are arranged on the conical part 12. The magnetic parts 17 are used to adsorb and stabilize the lifting clamping blocks 11 in the non-expanded state. A protective frame 18 is arranged on the right part of the installation bracket 1. Two sprockets 19 are rotatably arranged inside the protective frame 18. The sprockets 19 are connected to the adjacent second lead screws 8. A chain 20 is wound between the sprockets 19.
[0029] It should be noted that the formwork reinforcement structure of the reaction wall is mainly used for the formwork installation and steel pipe support of high-precision reaction walls in building structure laboratories. Its working principle can be divided into the following operation processes: First, drive the moving block 2 to slide horizontally along the mounting bracket 1 by rotating the first lead screw 3, driving the first mounting frame 4 to accurately align with the formwork columns of the reaction wall. After the position is calibrated, insert the first pin 5 to lock the relative angle between the first mounting frame 4 and the moving block 2, ensuring that the verticality error of the columns is ≤2 mm. At this time, the second lead screws 8 symmetrically arranged front and back rotate synchronously through the rotating disk 9, driving the mounting plate 7 to move along the axial direction of the lead screw, so that the contact column 6 applies a pre-tightening force to the steel pipe inside the reaction wall. The chain 20 and the sprocket 19 system ensure the synchronization of the displacements of the second lead screws 8 on both sides, preventing eccentric loading. After that, operate the adjusting screw 10 to axially advance under the internal thread drive of the contact column 6. The inclined surface of the conical part 12 pushes the lifting block 11 to expand radially outwards. The arc surface structure forms a surface contact with the inner wall of the steel pipe at an inclination angle of 15°. The fixed sleeve rod 14 is clamped with the conical part 12 through the positioning disk. The connecting rod 13 penetrates through the adjusting screws 10 on both sides to form a linkage, ensuring that the devices on both sides can be accurately aligned with the steel pipe. The magnetic part 17 provides an adsorption force when the block is not unfolded, preventing component displacement caused by transportation vibration. Finally, rely on the second mounting frame 15 to make a secondary connection with the formwork columns of the reaction wall, and slide the second pin 16 to achieve quick locking, forming a double-point constraint.
