Detailed Description
It is to be understood that the following detailed description is exemplary and is intended to provide further explanation of the utility model as claimed. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.
Interpretation of terms
In the application, "uniformly distributed" means that all the reinforcing ribs have the same width and the same depth and are uniformly distributed.
In the present application, the "ratio of the width of the reinforcing rib to the wall thickness of the core material" means: the ratio of the width of the reinforcing ribs to the wall thickness of the core material.
As the background art, in the composite heat-insulating board, the heat-insulating material is often used as the core material, but the inventor finds out through research that: the problems of insufficient strength and rigidity of the existing heat-insulating material under the conditions of fire prevention and energy-saving heat-insulating requirements generally exist. Therefore, the utility model adopts a graphite extruded sheet (SXPS) with the combustion performance of B1 grade, the thermal conductivity coefficient of less than or equal to 0.026 and better rigidity and strength as a core material, and reinforcing ribs are arranged on the graphite extruded sheet (SXPS).
Compared with the traditional heat-insulating material, the SXPS plate has better strength and rigidity besides flame retardance and heat-insulating property. Therefore, the requirements of the insulation board on rigidity and strength can be met under the condition that the ratio of the width of the reinforcing ribs to the wall thickness of the core material is smaller, so that the insulation board is made of an insulation material with a larger area in the whole structure, the insulation effect of the insulation board is better, and the interlayer bonding force is stronger.
The research finds that: along with the increase of the width of the reinforcing rib, the rigidity and the strength of the HA outer template cast-in-place concrete composite insulation board are enhanced, but if the width of the reinforcing rib is too large, the adhesive force between the adhesive layer and the core material is influenced. Therefore, in some embodiments, the width of the reinforcing rib is 5-6 mm, preferably 5mm, so as to take rigidity, strength, interlayer bonding force and heat insulation performance of the HA outer formwork cast-in-place concrete composite heat insulation board into consideration.
The existing HA external formwork cast-in-place concrete composite insulation board is generally connected with a wall body through a connecting piece, and therefore the insulation board needs to be lightened as much as possible so as to be convenient to install and fix. Thus, in some embodiments, the reinforcing bars of the present application take the form of hollow cylindrical structures, such as: the structure not only can meet the requirements of rigidity and strength of the reinforcing rib, but also has regular shape, convenient slotting, convenient production and processing and low raw material cost.
In some specific embodiment modes, in order to meet different building construction requirements, the core material is divided into two specifications: type I: the thickness of the core material is 75-100 mm, preferably 75, 80, 85, 90 and 100 mm; type II: the thickness of the core material is 83-103 mm, preferably 83, 88, 93, 98 and 103 mm.
