Description

A fiber-reinforced hollow lightweight partition board

technical field

The utility model relates to a partition wall board, in particular to a non-load-bearing fiber-reinforced hollow lightweight partition wall board used in an assembled concrete structure in the field of building industrialization.

Background technique

Since the comprehensive promotion of the policy of "no concrete and limited stickiness" at the beginning of this century, blocks have been used to replace solid clay bricks in the filling walls of traditional concrete structures, which has achieved certain resource saving effects and reduced structural weight to a certain extent. However, since the infill wall is still a masonry structural component, its integrity is poor. In previous destructive earthquakes, the seismic damage of the infill wall, such as cross shear cracks, is still one of the typical earthquake damages. And other anti-seismic measures, but did not fundamentally solve the occurrence of this earthquake damage. On the other hand, in order to prevent the infill wall from flashing and collapsing during an earthquake, the current codes or regulations stipulate that necessary connection measures must be taken between the masonry infill wall and the main structure, such as burying tie bars or laying steel bars In this way, the stiffness contribution of the infill wall to the main structure, especially the frame, must be considered, which increases the seismic action. Some scholars have proposed the method of adding horizontal and vertical flexible separation layers during the construction of the block wall, which is effective. The stiffness contribution of the block wall to the main body of the frame is reduced, but at the same time, the construction process is increased, the construction period is prolonged, and the traditional masonry construction quality is difficult to effectively guarantee. It can be seen that as long as the traditional on-site masonry construction method is still used, there are two fundamental problems: the construction period is long, and the construction quality cannot be absolutely guaranteed, which leads to the fact that the impact of the filling wall on the seismic performance of the main concrete structure cannot be fundamentally and effectively solved. The "manufacturing" method of prefabricated assembly of concrete structure houses represents an advanced development direction in the field of construction technology.

In the process of comprehensively promoting the policy of "no solids and limited sticking", many companies have begun to turn to the field of hollow wall panels, but most of the wall panels on the market are produced using chemical raw materials, which is a burden on the environment and energy. There are also many enterprises that use waste plant straw as raw materials and add adhesives, flame retardants, reinforcing agents, etc. to produce fiber wallboards. Although they meet the requirements of environmental protection in terms of straw waste utilization, some of their additives are toxic or difficult to decompose. The ingredients are not truly green and environmentally friendly, especially in the processing process, which basically needs to be processed by hot pressing, which requires large-scale equipment and instruments, and the cost is high and the energy consumption is high. Moreover, the surface plaster of a large number of wallboards is generally cracked, which seriously affects the use.
