Description

Technical Field

[0001] This application relates to the field of building staircase construction, specifically to a template adjustment bracket used for staircase construction shaping. Background Technology

[0002] As a crucial traffic component in buildings, the construction quality of staircases directly impacts the safety and lifespan of the structure. Traditional staircase construction methods primarily rely on on-site formwork erection and concrete pouring, with the support and angle adjustment of the bottom formwork being key aspects. However, existing staircase formwork methods have several shortcomings, such as unstable connections between the bottom formwork and supporting steel bars, and difficulties in angle adjustment that are time-consuming and labor-intensive. These problems not only affect construction efficiency but may also pose potential threats to the structural safety of the staircase.

[0003] Specifically, the problems with existing staircase formwork methods mainly include the following aspects:

[0004] 1. Because the bottom formwork of the staircase is designed with an inclination, it is usually connected to the supporting steel bars by a point connection. This connection method is not mechanically stable enough and is prone to causing the bottom formwork to slide downward during use, thereby affecting the structural stability of the entire staircase.

[0005] 2. When the angle of the staircase bottom formwork needs to be adjusted, the traditional method is to adjust the height of the scaffolding pipes. However, this method requires precise control of the height of each scaffolding pipe, making the operation cumbersome and prone to errors. This imposes a significant workload and difficulty on construction workers, directly affecting the construction quality and schedule of the staircase. Frequent angle adjustments also greatly reduce work efficiency and increase construction costs.

[0006] To address the aforementioned issues, improve the efficiency and quality of staircase construction, and ensure operational safety, it is necessary to design a new type of auxiliary adjustment bracket for staircase construction formwork. This bracket should be easy to operate, provide stable and reliable support, and have a simple and convenient angle adjustment mechanism. This would enable construction workers to quickly and accurately adjust the angle of the bottom formwork, thereby improving work efficiency. Summary of the Invention

[0031] Working Principle: When the auxiliary adjustment bracket for the staircase construction formwork is in operation, the assembled bracket is placed on the steel bars. It connects to the steel bars via support plates on the base of the support frame. Rotating the tightening member adjusts the distance between the tightening member and the steel bars, ensuring a tight fit between the end of the tightening member and the steel bars, thus increasing the stability of the bracket. The support plate and the bottom formwork timber form surface support, reducing localized stress concentration. Anti-slip pads are installed on the support plate to prevent the bottom formwork timber from sliding downwards. To adjust the angle of the support plate, first loosen the fasteners; a spring will then spring open the reinforcing plate that is tightly fitted to the adjustment frame. Then, rotate the adjusting member... The rotating mechanism causes the support rod to rotate, and the rack inside the adjusting port of the adjusting frame engages with the adjusting gear on the support rod, causing the support plate to move up and down. Rotating the adjusting component clockwise causes the support plate to move upward, and rotating it counterclockwise causes it to move downward, thus adjusting the angle of the support plate. After the angle of the support plate is adjusted, tightening the fasteners pushes the reinforcing plate towards the adjusting frame. The locking block engages with the rack, and the reinforcing plate fits tightly against the adjusting frame, fixing the adjusted support plate to the adjusting frame. This prevents instability caused by the support plate sliding downward under gravity, improving the safety of the staircase construction process.

[0032] The beneficial effects of this utility model compared with the prior art are:

[0033] 1. This utility model allows for quick adjustment of the angle of the support plate by adjusting the support mechanism and the adjustment port, thereby adapting to different construction needs, greatly improving operational efficiency, and reducing the time and labor intensity of manual operation.

[0034] 2. This utility model increases the support area, reduces local stress concentration, and improves the stability of the entire support structure by forming a surface support with the support plate and the bottom mold wooden block.

[0035] 3. The support plate of this utility model is equipped with anti-slip pads to prevent the bottom mold from sliding downwards, thus increasing safety.

[0036] 4. The support plate on the base of the support frame of this utility model is in the shape of an "E" or a "mountain". It is connected to the steel bar by the support plate on the base of the support frame to prevent the support frame from sliding under force and enhance the stability of the support during operation.

[0037] 5. The support frame base of this utility model is provided with a tightening component. The distance between the tightening component and the steel bar can be adjusted according to actual needs, so that the support frame base and the steel bar are tightly fitted, and the support can adapt to steel bars of different specifications, thereby enhancing the adaptability of the support.

[0038] 6. This utility model improves the safety and stability of the bracket during use by fixing the adjustment frame and support plate with fasteners.

[0039] 7. This utility model incorporates a spring in the adjustment support mechanism, which allows the spring to spring away from the reinforcing plate that is tightly fitted with the adjustment frame when the fasteners are loosened during the adjustment of the support plate angle, making it easier and less strenuous to use.
