Concrete close-column and gypsum composite external wall panel without cold bridge

Abstract

The invention relates to a concrete close-column and gypsum composite external wall panel without a cold bridge, comprising high-strength gypsum, cement, pulverized fuel ash, waterproofing agent, fiber bars, connecting bars A, connecting bars B, light heat insulation material and plates with concrete preset cavities in the first process and on-site pouring concrete in the cavity in the second process and is manufactured by using a high-strength gypsum board layer, a light heat insulation material layer, a high-strength gypsum preset concrete cavity plate layer and a reinforced concrete close-column poured in a wall board preset concrete cavity from outside to inside; all the layers are connected by the connecting bars A and the connecting bars B which are uniformly distributed, two ends of the connecting bars are vertically split into 4-10 pieces, the high-strength gypsum board layer and the preset concrete cavity plate layer are internally provided with the fiber bars, a preset concrete cavity is provided with steel bars on site and is poured synchronous with the reinforced concrete of the integral structure of a building to form a reinforced concrete close-column; and the high-strength gypsum preset concrete cavity plate layer and the reinforced concrete close-column both participate in structural stress of the building. The wall panel integrates a plurality of functions including enclosing, bearing, sound insulation, heat insulation, seismic resistance and fire prevention and is suitable for industrialization of production modes of residences.

Description

technical field [0001] The invention relates to a gypsum composite wallboard, in particular to a concrete dense column gypsum composite non-cold bridge external wallboard integrating energy saving, low consumption, environmental protection, building load bearing and multiple functions. Background technique [0002] The exterior walls of existing residential buildings have the following deficiencies: traditional building materials are self-heavy, high energy consumption, single function, materials and processes are repeatedly superimposed, on-site manual wet work is heavy, many processes, high cost, long construction period, and low product quality. Especially after adding the insulation layer, the life of the insulation material and the main body of the building is not synchronized, and it needs to be replaced repeatedly, which is costly, flammable and unsafe, and the construction technology is backward.
