Concrete multi-columned gypsum composite external wall panel

Abstract

The invention provides a concrete multi-columned gypsum composite external wall panel. The preparation method of the composite external wall panel comprises the following steps: making multi-cavity plates from high-strength gypsum, a waterproofing agent, fiber-reinforced polymer (FRP) bars and light heat-insulating materials; according to weather conditions of regions with different latitudes, determining 3-6 cavity plate layers, arranging the cavity layers with equal length in a staggered manner, and uniformly distributing the FRP bars on plate walls and ribs; and arranging the light heat-insulating materials at 2-5 cavity layers at the outer side, reserving concrete cavities at the inner side, configuring reinforced bars on site, and casting the configured reinforced bars along with reinforced concrete of an overall building structure so as to form multi-columned reinforced concrete in the plates. The gypsum plate bodies and the multi-columned reinforced concrete in the plate cavities participate in load-bearing and anti-seismic stress of a building structure. The wall panel has the functions of enclosure, load bearing, sound insulation, heat preservation, seismic resistance, fire prevention and the like; and the wall panel has the advantages of integrated multiple functions such as energy conservation and consumption reduction as well as environmental protection, economy and applicability, capability of realizing industrial production and integrated application, and the structural mechanism of the wall panel has universality and advancing performance for coping with four-step energy conservation of a residential house.

Description

technical field [0001] The invention relates to a gypsum composite wallboard, in particular to a concrete dense-column gypsum composite exterior wallboard which combines multiple functions, energy saving, low consumption, environmental protection and bearing building loads. 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, superposition of materials and processes, large amount of manual and wet work on site, many processes, high cost, long construction period, low product quality, difficult to control. In particular, if the insulation layer is repeatedly superimposed, the insulation material is not synchronized with the life of the main body, and needs to be replaced repeatedly, which is costly, flammable and unsafe, and the construction technology is backward. Contents of the invention [0003] The main purpose of the ...
