Description

Prestress ALC plate Technical Field The utility model relates to the technical field of building construction, in particular to a prestress ALC plate. Background At present, the filling wall (inner wall and outer wall) in the building industry mainly has two construction modes, one is the most traditional bricking and plastering process, and the construction mode has low construction efficiency, large manual consumption, difficult quality control and low wall flatness. The second is the assembled ALC plate wall, this kind of construction method is formed by the combination of many independent ALC boards, and the fracture problem of junction between the board is unable to be solved (because of temperature and humidity changes cause yet). In view of this, we propose a pre-stressed ALC panel to thoroughly solve the wall cracking problem. Disclosure of utility model The utility model aims to provide a prestress ALC plate which solves the problems in the prior art and can effectively prevent cracking at a plate wall joint. In order to achieve the above object, the present utility model provides the following solutions: The utility model provides a prestress ALC plate, which comprises a plate body and prestress pull rods, wherein the plate body comprises a first plate body and a second plate body, grooves are formed in two ends of the first plate body in the width direction, one end of the second plate body in the width direction is provided with a groove, the other end of the second plate body is provided with a convex block matched with the groove, one first plate body and a plurality of second plate bodies are sequentially spliced through the grooves and the convex blocks, reinforcing steel meshes are arranged in the plate body, a plurality of prestress wire penetrating holes are formed in the plate body at intervals along the length direction, the prestress wire penetrating holes extend along the width direction of the plate body, and the prestress pull rods are penetrated into the corresponding prestress wire penetrating holes in the spliced plate bodies and are respectively connected with locking nuts at two ends in a threaded manner. In an embodiment, the prestress wire penetrating holes are provided with prestress wire penetrating buried pipes, and the prestress pull rods are penetrated in the corresponding prestress wire penetrating buried pipes in the spliced plate bodies.
