Problems solved by technology

[0003] Roof panels, floor panels or wall panels use ordinary reinforced concrete as the frame rib structure, which has the disadvantages of heavy weight, high brittleness, and poor durability; while the upper and lower layers of ordinary mortar or polymer mortar are usually dense and crack-resistant Poor performance; when the cementitious material of the upper and lower layers of the board and the lightweight concrete rib is magnesium oxychloride cement, the lightweight filler commonly used in magnesium materials is saw foam. Although saw foam can reduce weight, its water absorption Too much will increase the amount of brine, and excessive brine will easily make the product absorb moisture and return to brine, resulting in a decrease in strength and a short service life

Abstract

The invention relates to an environmentally-friendly, energy-saving and fireproofing lightweight roof panel, floor plate or wallboard, which comprises an upper surface layer, a lower surface layer and frame ribs. Insulating layers are arranged between the upper surface layer and the lower surface layer, and are cement polymer foamed plastic powder lightweight insulating plates or are formed by compounding the cement polymer foamed plastic powder lightweight insulating plates and any one of molded polystyrene foam plates, extruding-molded polystyrene foam plates and rock-wool slabs respectively; fiberglass alkaline-resistant mesh fabric is arranged in the upper surface layer and the lower surface layer; the frame ribs are fixedly connected to the lower surface layer; and an anticorrosion steel reinforcement frame is arranged in the frame ribs. In the environmentally-friendly, energy-saving and fireproofing lightweight roof panel, floor plate or wallboard of the invention, the lightweight insulating plates and lightweight surface layer mortar are manufactured by foamed plastic powder; the foamed plastic powder and heat-preservation foamed plastic form particles are applied to lightweight concrete; and materials for the upper and lower surface layers and the frame ribs are enhanced by two or more assorted fibers so as to fulfill the aims of lightweight, high strength, energy saving, sound insulation, fireproofing, crack resistance and durability.

Description

technical field [0001] The invention relates to an environment-friendly, energy-saving and fireproof lightweight roof panel, floor panel or wall panel, which belongs to a kind of building materials. Background technique [0002] Traditional cement concrete roof panels, floor panels or wall panels, due to their own weight, have no insulation effect, and need to be treated on site for thermal insulation construction. Now they are gradually replaced by thermal insulation roof panels, floor panels or wall panels. Existing composite thermal insulation roof panels, floor panels or wall panels mostly use molded polystyrene plastic foam boards and extruded polystyrene plastic foam boards. Poor performance. Successive fire accidents caused by building external thermal insulation systems and external decoration materials show that the fire safety issues of building energy conservation and building decoration are very prominent and need to be resolved urgently. With the development o...
