Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a wall column base support structure. Background Technology

[0002] In the wall and column pouring construction phase of building projects, the wall and column bases, as a critical connection between the wall / column and the foundation, directly affect the overall structural stability and functionality of the building. Currently, due to the lack of effective support structures at the wall and column bases, the concrete exerts significant lateral pressure on the formwork during pouring. Furthermore, during the subsequent curing stage, the formwork is prone to deformation and displacement, leading to inadequate sealing at the connection between the wall / column base and the foundation, and consequently, leakage problems.

[0003] Leakage not only affects the functionality of building interior spaces, leading to dampness and mold on walls, but also erodes the foundation structure of walls and columns, reducing structural durability and increasing the cost and difficulty of later maintenance. Current construction methods often employ traditional approaches such as temporary timber supports; however, these methods have significant drawbacks: firstly, timber supports lack stability and cannot withstand the lateral pressure of concrete pouring, easily leading to support failure and compromising the quality of wall and column base construction; secondly, the assembly and disassembly process of temporary timber supports is cumbersome, and the timber is easily damaged during use, making reuse difficult, resulting in low construction efficiency and increased material costs, failing to meet the comprehensive requirements of modern building construction for quality, efficiency, and cost control. Therefore, there is an urgent need to develop a simple, stable, easy-to-operate, and reusable wall and column base support structure to address the shortcomings of existing temporary timber supports. Utility Model Content

[0004] In order to overcome the problems of poor stability, easy leakage, inconvenient assembly and disassembly, and difficulty in reuse of existing wall and column foot supports in wall and column casting construction, this utility model provides a wall and column foot support structure that achieves stable support for wall and column feet, effectively prevents leakage, and improves construction convenience and economy.

[0005] The technical solution of this utility model is as follows:

The end of the inclined support plate away from the horizontal support plate is provided with a hook, and the hook cooperates with the double steel pipe of the through-bolt fixing assembly for fixing the wall column template.

[0007] When the hook is attached to the double steel pipe of the through-bolt fixing assembly, the end of the inclined support plate away from the hook abuts against the ground, and the end of the horizontal support plate away from the inclined support plate abuts against the lower end of the square steel of the through-bolt fixing assembly.

[0027] Please see Figures 1 to 3 This utility model provides a wall column foot support structure that cooperates with the through-bolt fixing assembly 4 for fixing the wall column template 3 to support the wall column foot, preventing deformation and displacement of the wall column foot part of the wall column template 3 under the action of concrete during wall column pouring, and preventing leakage. The wall column foot support structure includes an inclined support plate 1 and a horizontal support plate 2 rotatably connected to the inclined support plate 1. The end of the inclined support plate 1 away from the horizontal support plate 2 is provided with a hook 11, which cooperates with the double steel pipe 41 of the through-bolt fixing assembly 4.

[0028] Installation steps: First, after the wall column formwork 3 and the through-bolt fixing assembly 4 are installed in place according to the design, check the integrity of the wall column foot support structure to ensure that the inclined support plate 1, horizontal support plate 2, and hook 11 are not deformed or damaged, and can be used normally. Then, hook 11 onto the double steel pipe 41 of the through-bolt fixing assembly 4, and adjust the hooking angle so that the end of the inclined support plate 1 away from the hook 11 contacts the ground and is pressed firmly against the ground. Finally, adjust the rotation angle of the horizontal support plate 2 so that the end of the horizontal support plate 2 away from the inclined support plate 1 abuts against the lower end of the square steel 42 of the through-bolt fixing assembly 4, so as to support the wall column foot of the wall column formwork 3. The wall column foot support structure can be reasonably arranged with multiple sets of supports around the wall column foot according to the length and width of the wall column, generally one set every 1m, to ensure that all parts of the wall column foot are effectively supported, and the support spacing is uniform to avoid insufficient local support.

[0029] Disassembly steps: First, lift the end of the inclined support plate 1 away from the hook 11 off the ground. Then, remove the hook 11 from the double steel pipe 41 of the through bolt fixing assembly 4. The entire wall column foot support structure can then be disassembled from the wall column foot position. The disassembled wall column foot support structure can be reused in subsequent wall column pouring construction, achieving reuse and reducing construction costs.

[0030] During the pouring of the wall column, the transmission path of the concrete lateral pressure can be summarized as follows: concrete lateral pressure F → wall column formwork 3 → through bolt fixing assembly 4 (double steel pipe 41, square steel 42) → wall column foot support structure (hook 11 → inclined support plate 1 → horizontal support plate 2) → ground. The specific transmission process is as follows:

[0031] 1. When concrete applies a horizontal outward lateral pressure F to the wall column formwork 3, the wall column formwork 3 tends to deform and displace outward.

[0032] 2. The deformation trend of the wall column formwork 3 is constrained by the through-bolt fixing assembly 4 (the double steel pipe 41 horizontally clamps the wall column formwork 3, and the square steel 42 vertically limits it), and the lateral pressure F is transmitted to the double steel pipe 41 and square steel 42 of the through-bolt fixing assembly 4.

[0033] 3. The double steel pipe 41, through its connection with the hook 11, transfers part of the lateral pressure to the inclined support plate 1; the square steel 42, through its abutment with the horizontal support plate 2, transfers the constraint reaction force to the horizontal support plate 2.

[0034] 4. The inclined support plate 1 transmits the force to the ground, and the horizontal support plate 2 assists in stabilization through its rotational connection with the inclined support plate 1. Finally, the ground provides the reaction force to balance the entire load.

[0035] Please see Figure 1 In one embodiment, two hooks 11 are provided, spaced apart on the left and right. The two hooks 11 form a two-point constraint, which, compared to the single-point constraint of a single hook 11, can more stably fix the inclined support plate 1 to the double steel pipe 41. Even if the formwork shakes slightly during pouring, the two hooks 11 can prevent the hooks 11 from slipping off the double steel pipe 41 through two-point limiting, further ensuring that the support system does not fail and indirectly reducing the risk of leakage at the wall column foot. At the same time, the distance between the two hooks 11 is greater than the diameter of the through-bolt 43 of the through-bolt fixing assembly 4, reserving sufficient space for the through-bolt 43, ensuring that the hooks 11 do not conflict with the through-bolt 43 when hooked, solving the installation jamming problem and improving the convenience of construction.

[0036] Please see Figures 1 to 3 In one embodiment, the hook 11 is positioned upwards. When the hook 11 is positioned upwards, its opening direction can be completely aligned with the horizontal axis of the double steel pipe 41, that is, the hook 11 hooks the double steel pipe 41 from below, forming a downward hook-type connection; compared with the hook 11 facing downwards (which is easy to slip off from above), the upward-facing hook 11 can form a natural engagement with the double steel pipe 41, making the connection more secure and less likely to detach due to vibration or lateral pressure impact.

[0037] In one embodiment, the hook 11 and the inclined support plate 1 are integrally formed, which can eliminate weak points in the connection and improve the overall load-bearing strength. If the hook 11 and the inclined support plate 1 are connected by welding or bolts, the connection is prone to becoming a weak point due to welding defects (such as incomplete welding) or loose bolts; when the inclined support plate 1 is subjected to axial pressure, the connection may be pulled out or broken. However, integral molding makes the hook 11 and the inclined support plate 1 a seamless integral component, with no loss in force transmission, significantly improving the overall tensile and compressive strength, and enabling it to withstand greater lateral pressure from concrete, thus avoiding support failure.

[0038] Please see Figure 1 , Figure 2 In one embodiment, the end of the inclined support plate 1 away from the hook 11 is provided with a ground-contacting sharp corner structure 12. The ground-contacting sharp corner structure 12 can concentrate the vertical component of the inclined support plate 1 (the force transmitted to the ground) at the sharp corner, increase the local contact pressure, embed the sharp corner into the ground, form an anti-slip anchor, prevent the ground-contacting end of the inclined support plate 1 from slipping, and improve the reliability of the support.

[0039] Please see Figure 1 , Figure 2 In one embodiment, the inclined support plate 1 is rotatably connected to the horizontal support plate 2 via a rotating shaft 13, allowing the horizontal support plate 2 to rotate freely around the rotating shaft 13. This allows for flexible adjustment of the contact angle between the horizontal support plate 2 and the square steel 42, ensuring that the end of the horizontal support plate 2 furthest from the inclined support plate 1 is fully in contact with the lower end of the square steel 42. This avoids ineffective support due to mismatched angles, resulting in only partial contact and failure to transmit constraint reaction force. Furthermore, during installation, precise calibration of the angle between the horizontal support plate 2 and the inclined support plate 1 is unnecessary. Workers only need to manually rotate the horizontal support plate 2 until it contacts the square steel 42 after the inclined support plate 1 is hung. No additional cutting, welding, or adjustment is required, significantly reducing installation time and making it particularly suitable for rapid on-site construction needs.

[0040] Please see Figure 1 , Figure 2 In one embodiment, the horizontal support plate 2 is an adjustable telescopic plate structure. During on-site construction, the horizontal distance between the inclined support plate 1 and the square steel 42 may vary due to differences in wall column dimensions and the installation height of the double steel pipes 41. If the length of the horizontal support plate 2 is fixed, it may be too short to properly engage with the square steel 42, or too long to push the square steel 42 out of place. Using a telescopic plate structure allows for precise matching of the actual distance between the inclined support plate 1 and the square steel 42 by adjusting the length, ensuring that the horizontal support plate 2 can precisely engage with the square steel 42. This improves the versatility of the wall column base support structure and reduces the cost of repeated procurement.

[0041] Specifically, the telescopic plate structure includes a mounting plate 21 with a sliding cavity 211 at one end, a telescopic plate 22 that slides through the sliding cavity 211 at one end, and a locking member 23 for locking the telescopic plate 22 and the mounting plate 21 together. The end of the mounting plate 21 away from the sliding cavity 211 is rotatably connected to the inclined support plate 1. The telescopic plate structure described above, by sliding the telescopic plate 22 through the sliding cavity 211 of the mounting plate 21, ensures that the telescopic plate 22 only extends and retracts along the horizontal axis, avoiding misalignment that could cause the horizontal support plate 2 to make incomplete contact with the square steel 42. This ensures that the axis of the horizontal support plate 2 remains perpendicular to the square steel 42 after extension and retraction, and that the force transmission path does not deviate. By providing the locking member 23, the telescopic plate 22 and the mounting plate 21 can be rigidly fixed after the length is adjusted, forming a complete rigid rod. This ensures that the length of the horizontal support plate 2 remains unchanged when under pressure, and that the force can be stably transmitted to the inclined support plate 1, preventing support failure.

[0042] Furthermore, the locking component 23 includes two locking screws. The mounting plate 21, near the telescopic plate 22, has screw holes on both its left and right sides that match the locking screws. These screw holes are connected to the sliding cavity 211. The two locking screws, in conjunction with the two screw holes, lock the telescopic plate 22 to the mounting plate 21. The locking screws are standard construction tools; a wrench is sufficient for operation, requiring no additional training from workers. After adjusting the length of the telescopic plate 22, simply tightening the screws on both sides completes the locking process. The operation is simple and efficient, suitable for the high-intensity, fast-paced construction demands of the site.

[0043] Please see Figure 1 , Figure 2 In one embodiment, a thickened support portion 221 is provided at the end of the telescopic plate 22 away from the mounting plate 21. The thickness of the thickened support portion 221 is greater than the thickness of the telescopic plate 22, generally more than twice the thickness of the telescopic plate 22. The thickened support portion 221 can increase the compressive section modulus of the end of the telescopic plate 22, enabling it to withstand greater local pressure and avoid end deformation and damage. At the same time, it can increase the contact area with the square steel 42 to better support the wall column base.

[0044] In one embodiment, both the inclined support plate 1 and the horizontal support plate 2 are made of steel plates with a thickness of 20mm. The use of 20mm thick steel plates for both the inclined support plate 1 and the horizontal support plate 2 provides high load-bearing strength, strong resistance to deformation, adaptability for reuse, reduced costs, structural stability, and high force transmission efficiency.
