A combined puffed stone stress insulation panel

Abstract

The invention provides a combined bentonite stress heat insulation face plate. For the combined bentonite stress heat insulation face plate, a filler hemisphere shell layer comprises filler hemisphere shells which are arranged closely, the openings of the filler hemisphere shells face down, and a heat insulation conducting material is filled in the filler hemisphere shells; an air hemisphere shell layer comprises air hemisphere shells which are arranged closely, the openings of the air hemisphere shells face up and are opposite to the openings of the corresponding filler hemisphere shells; a radiation-proof material layer is arranged between the filler hemisphere shell layer and the air hemisphere shell layer, an upper-layer heat insulation material layer is arranged outside the filler hemisphere shell layer, an upper-layer protection layer is arranged outside the upper-layer heat insulation material layer, a lower-layer heat insulation material layer is arranged outside the air hemisphere shell layer, and a lower-layer protection layer is arranged outside the lower-layer heat insulation material layer. The combined bentonite stress heat insulation face plate has a general heat transfer coefficient of 0.35-0.45(w / m.k), a thermal inertia index of not less than 2.5, a plate dead weight of 0.25kN / m<2> and a bearing capacity of 2.0kN / m<2>; in addition, the plate also has functions of fire prevention, sound insulation, wind resistance and the like and particularly has fire endurance being not less than 2.0h and air sound insulation being not less than 45dB. Moreover, the plate has large integral rigidity and strong resistance against strong breeze.

Description

technical field [0001] The invention relates to the technical field of building components, in particular to a combined puffed stone stress-insulation panel. Background technique [0002] The accurate definition of combined puffed stone load-bearing thermal insulation board should be a light board that uses combined technology, uses high-quality puffed stone as the main material, and highlights the thermal insulation function of the force. Light board is a general term for multifunctional boards with lightweight properties. Light panels can be divided into three categories according to their shape, composition, material, and stress; namely, aerated concrete, profiled steel, sandwich panels, and steel frames. Air-entrained concrete light panels have limited the breadth and depth of their development due to their large material volume, high thermal conductivity, and low bearing capacity; profiled steel sandwich light panels have long-term It dominates the demand market for h...

Problems solved by technology

Air-entrained concrete light panels have limited the breadth and depth of their development due to their large material volume, high thermal conductivity, and low bearing capacity; profiled steel sandwich light panels have long-term It dominates the demand market for housing building enclosure structures, but its fatal flaws such as durability, fire resistance, load-bearing, and air permeability may make it withdraw from the light board market; steel frame light boards are in the stage of "seven heroes competing for hegemony", The same goal but difficult to unify, lack of leadership
