Description

Technical Field

[0001] The present invention relates to the technical field of shockproof buffering and stabilizing devices, and in particular to a shockproof buffering and stabilizing device and a stabilizing method for a cold storage floor formwork support system. Background Art

[0002] With the rapid development of the cold chain logistics industry, the scale and number of cold storage facilities, as important storage facilities, have continued to rise to meet the storage needs of food, medicine and other supplies. These extreme temperature conditions pose huge challenges to building materials and construction processes. During the construction of the cold storage floor, the formwork support system, as a key temporary structure to ensure the pouring and forming of concrete, undertakes the important task of transmitting and distributing the floor load. At the same time, the cold storage floor formwork support system faces multiple complex loads during the construction phase. On the one hand, the lateral pressure and impact force generated during concrete pouring are large, which requires extremely high strength and stability of the support system. On the other hand, the periodic vibration generated during the operation of the cold storage refrigeration equipment, as well as the external vibration caused by the movement of surrounding transport vehicles and loading and unloading of goods, will continuously act on the floor formwork support system. If these vibrations cannot be effectively absorbed and buffered, they will not only affect the quality of the concrete pouring, resulting in cracks and honeycombed defects in the floor, but may also cause the support system to become unstable, resulting in serious safety accidents such as formwork collapse.

[0003] At present, the anti-vibration buffer stabilization device of the support system on the market is mainly composed of shock-absorbing components and buffer components. The traditional anti-vibration buffer stabilization device of the cold storage floor formwork support system has many shortcomings. In terms of shock-absorbing structure, most devices adopt a single shock-absorbing method, such as relying on simple rubber gaskets for buffering, which is difficult to cope with complex and changeable vibration conditions. The rubber gasket will quickly harden and lose its elasticity in a low temperature environment, resulting in a significant decrease in shock absorption performance and inability to effectively absorb and dissipate vibration energy. In terms of connection and fixing methods, some components of the support system are not firmly connected, and bolt connections are prone to loosening under vibration. Welding parts may also suffer from fatigue cracking due to repeated vibrations, reducing the overall stability of the support system. Moreover, the existing buffer materials The material performs poorly in terms of low temperature resistance and durability, and cannot adapt to the special environment of cold storage for a long time. Frequent replacement of buffer materials not only increases construction costs, but also affects construction progress. In addition, with the promotion of building industrialization and green construction concepts, new requirements are put forward for the installation convenience and reusability of the shock-proof buffering and stabilization device of the cold storage floor formwork support system. The installation process of traditional devices is complicated, consumes a lot of manpower and time, and is difficult to reuse, which does not conform to the development trend of modern construction. Against this background, the development of a new type of floor formwork support system shock-proof buffering and stabilization device suitable for the special environment of cold storage to improve construction quality, ensure construction safety, and reduce construction costs has become an urgent need to promote the high-quality development of the cold storage construction industry. Summary of the Invention

At the same time, the outer wall of the gear plate 2 can slide on the outer wall of the sliding groove, so that the support column can be installed on the top of the base plate. At the same time, the gear plate 1 can mesh with the gear plate 2, thereby enhancing stability after installation and facilitating operation.

[0015] The present invention has the following beneficial effects: 1. In the present invention, fixed blocks are fixed at the upper and lower ends of the inner wall of the support column. At the same time, when the sliding column is subjected to pressure from the top, it will be transmitted downward by spring three while performing the first buffering.
