Assembled heat-preservation aerated concrete composite wall plate and manufacturing method thereof

Abstract

The invention discloses an assembled heat-preservation aerated concrete composite wall plate which comprises an aerated concrete plate, a cement fiber plate, pre-buried parts and an outer decoration layer. The B03-grade aerated concrete plate is a heat-preservation material, but the strength of the plate is only 1 / 10 of that of common concrete. To reduce the thickness as much as possible on premise that strength requirements of outer wall plates are met, and meet the purpose of integration of properties and decoration, the cement fiber plate with high strength is compounded with the outer side of aerated concrete, and the outer side of an FRP (Fiber Reinforce Plastic) plate is coated by the outer decoration layer. The aerated concrete plate and the cement fiber plate are connected with steel sleeve pre-buried parts inside the aerated concrete through bolts, when the wall plate is bent, the outer wall plate, namely the cement fiber plate is tensioned, the tension is conducted to a cement fiber plate at another end through the bolts, then the involvement degree of the aerated concrete plate in stress is reduced, and the aerated concrete plate barely bears the tension, but only takes a part of pressure, so that the aerated concrete is prevented from sliding or damage caused by low tension resistance. Regular reinforcement is replaced by FRP ribs in the middles of the pre-buried parts, and cold bridges can be avoided.

Description

technical field [0001] The invention relates to the field of building material design, in particular to an assembled aerated concrete slab thermal insulation composite wallboard. Background technique [0002] At present, my country is vigorously promoting the development of green buildings, and the development of corresponding green building materials is also urgent. Air-entrained concrete wall panels have been widely used in various buildings in my country as interior and exterior walls. Air-entrained concrete has excellent properties such as light weight, heat preservation, and fire resistance. However, air-entrained concrete is easy to be bumped during transportation, and its strength is about one-tenth of that of ordinary concrete. After it is applied to high-rise buildings, it is subject to large wind loads and is prone to cracking. These shortcomings have restricted the development and application of air-entrained concrete wall panels. [0003] The composite wallboa...
