Description

Novel general buffer structural member for building and processing device and processing method Technical Field The invention belongs to the technical field of buffer materials, and relates to a novel general buffer structural member for a building, a processing device and a processing method. Background In the field of building engineering, the buffer structural member is a core component with comprehensive functions of bearing, buffering and energy consumption, and has the core function of absorbing adverse effects such as earthquake load, impact load (such as falling rock impact, vehicle collision and construction impact), structural deformation stress (such as surrounding rock convergence and temperature deformation) and the like through the characteristics of self structures or materials, so that the transmission of the load to a main structure of the building is reduced, the main structure is prevented from cracking, breakage or failure, and the safety and durability of the building engineering are ensured. The application scene of the member covers a plurality of subdivision directions in the building field, namely the deformation of surrounding rocks of tunnels and the damage of impact load to a supporting structure are required to be dealt with in underground engineering, the relative deformation of a floor slab and a wall body under the action of earthquake is required to be relieved in high-rise buildings, the structural cracking risk is reduced, the impact of wind load and temperature stress to a connecting node of a curtain wall and a main structure is required to be buffered in curtain wall construction of a building, the loss of vibration generated by vehicle passing to a bridge support is required to be reduced in bridge engineering, and the buffering requirements such as anti-collision and noise reduction are required to be realized in indoor decoration and public buildings. However, there are significant limitations to the cushioning members of the existing construction field: 1. The traditional buffer components are mostly designed specially for scenes, such as special PVC two liners for tunnels, special metal buffers for building curtain walls, special rubber supports for bridges and the like, and lack general products capable of being matched across scenes. The design pertinency of special component is strong, is difficult to satisfy different building scene and to the differentiation demand of cushioning strength, size, waterproof nature, durability, leads to need to purchase multiple type component in the engineering, increases purchase and construction management cost. 2. The traditional hard buffer components (such as metal alloy parts, PVC/PE/MPP hard pipes and ABS components) have high raw material unit price, the engineering cost is greatly increased in large-scale application, and the hard components occupy large space for transportation and storage, are easy to damage due to collision, and further increase extra expenditure. Meanwhile, although the cost of part of flexible buffer parts (such as a simple rubber pad and a common woven bag packaging part) is lower, the problems of insufficient strength, poor waterproof property, weak stretching resistance and the like exist, and the flexible buffer parts are easy to age and damage after long-term use and need frequent replacement and maintenance. 3. The traditional hard buffer member has strong rigidity and limited strain capacity, is difficult to realize buffer energy consumption through self deformation when encountering dynamic loads such as earthquake, structural deformation and the like, and is easy to cause load to be directly transmitted to a main structure, while the traditional flexible buffer member has strong deformation capacity but insufficient bearing strength, is easy to generate excessive deformation or failure under the action of larger load, and cannot meet the bearing requirement of a building structure. In addition, the compatibility of part of the buffer components and the main building materials (such as concrete and mortar) is poor, and the interface stripping easily occurs after long-term use, so that the whole supporting or connecting effect is affected. Therefore, aiming at the core requirements of different scenes in the building field on general adaptation, low cost, high strength, strong buffering and good durability of the buffering component, the invention designs a novel general buffering structural component for building, a processing device and a processing method, and aims to solve the defects in the prior art. Disclosure of Invention The invention aims to overcome the defects in the prior art and provides a novel general buffer structural member for a building, a processing device and a processing method. The technical scheme adopted for solving the technical problems is as follows: a novel general buffering structural member for a building is characterized by comprising a waterproof woven bag a
