Building sandwich composite wallboard

Abstract

The invention discloses a building sandwich composite wallboard, which comprises a concrete external wallboard and a concrete internal wallboard, a heat-insulation layer plate is arranged between the external wallboard and the internal wallboard, a nonmetal connecting bar is arranged in the external wallboard, the heat-insulation layer plate and the internal wallboard, a bar body is arranged at the central part of the nonmetal connecting bar, an annular tooth is arranged on the bar body, an annular baffle plate is arranged at one side of the bar body, an annular seal bench is arranged at opposite side of the bar body, a first anchoring body is connected to a seal bulge loop, a second anchoring body is connected to the annular baffle plate, the annular baffle plate is positioned at the connection part of the heat-insulation layer plate and the internal wallboard, the annular seal bench is positioned in the heat-insulation layer plate at the connection part of the heat-insulation layer plate and the external wallboard, the annular tooth can be positioned in the heat-insulation layer plate, the first anchoring body is positioned in the external wallboard, and the second anchoring body is positioned in the internal wallboard. According to the sandwich composite wallboard, the three layer structure enables mutually and firmly connection, wallboard strength is greatly increased, the connecting bar has good seal function while passing through the heat-insulation layer, so that heat insulation effect can be greatly increased.

Description

technical field [0001] The invention relates to a building wallboard, which is a building sandwich composite wallboard. Background technique [0002] Since the traditional building wall construction methods do not meet the standards of energy saving and pollution reduction required in modern buildings, those skilled in the art have designed composite wall panels to replace the walls. This wall panel generally has a three-layer structure, with two layers of concrete The insulation layer is sandwiched, and the three-layer boards are connected together by metal connectors. This kind of wallboard is directly used for construction after being made, thereby solving many deficiencies in traditional construction methods. However, it is found that the wall body of this wallboard is very prone to cracks during use, and in severe cases, the outer layer of the wall will fall off. For this reason, the application of this composite wall in the field is gradually decreasing, which limits...
