Lightweight partition board with net rack and fiber-reinforced hollows and splicing method thereof

Abstract

The invention provides a lightweight partition board with a net rack and fiber-reinforced hollows and a splicing method thereof, and relates to the prefabricated partition boards of assembly type concrete structures in the field of architectural industrialization. The lightweight partition board comprises a board body, steel wire meshes, obliquely inserted bars, positioning grooves and cavities, wherein the obliquely inserted bars are fixedly connected with the upper steel wire mesh and the lower steel wire mesh to form the space net rack, the board body is formed by casting through ceramsite fiber concrete, and the upper surface and the lower surface of the board body are formed into natural rough surfaces through special formworks with foveolate protrusion structures. According to the lightweight partition board with the net rack and the fiber-reinforced hollows and the splicing method thereof, the problems that an existing partition board is prone to cracking, low in strength and high in water absorption are solved, the factory prefabrication can be achieved, the self weight is low, the flexible connection with a main body can be achieved, shock resistance can be better achieved, the construction is quick, the manufacturing cost is low, energy conservation and environment protection are achieved, safety and reliability are achieved, and sound insulation and heat preservation effects are good.

Problems solved by technology

[0002] 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 such 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 laying 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 extended, and the quality of traditional masonry construction 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

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, high cost and high energy consumption

In addition, the plaster on the surface of a large number of wallboards is generally cracked, which seriously affects the use
