Problems solved by technology

[0003] (1) Both hollow blocks and cast shear walls need to add mesh concrete to the external wall, as well as external insulation and fireproof materials. The process is cumbersome and requires on-site construction
[0004] (2) Due to the on-site construction, there are likely to be jerry-built links in the construction
[0005] (3) On-site construction quality cannot be accurately controlled, and the wall is prone to hollowing, cracking, water seepage, falling off and other common quality problems
[0006] (4) High comprehensive cost: Since the exterior wall requires 5 to 6 processes, labor costs and material costs increase
[0007] (5) Long construction period: Due to the cumbersome procedures and each process requires a period of time to maintain health, the construction period is very long

Abstract

The invention discloses an outer wall self-thermal insulation wallboard and a production method of the outer wall self-thermal insulation wallboard, belonging to the technical field of outer walls in building industry. The invention provides a factorized outer wall self-thermal insulation wallboard which is reliable in quality, short in construction period and low in cost, and a production method of the factorized outer wall self-thermal insulation wallboard. The outer wall self-thermal insulation wallboard comprises a cuboid-shaped concrete board; the structural feature is that a cuboid-shaped through hole is formed in the concrete board along the width direction of the concrete board; a plurality of through holes are formed in the concrete board in the length direction and distributed in a straight line; the through holes are internally filled with extruded sheets or polyurethane; glass fiber gelatin silk cloth layers are respectively arranged between the through holes and the outer surface of the concrete board; and the concrete board is made of magnesium oxychloride cement or silicate cement.

Description

Technical field [0001] The invention relates to a building wall material and a preparation method thereof, in particular to an external wall self-insulating wallboard using Portland cement concrete benzene board or polyurethane as the main raw material and a preparation method thereof, and belongs to the exterior wall technology of the construction industry field. Background technique [0002] How to reduce costs and develop efficient and convenient exterior wall building materials technology has always been a technical and economic issue that the construction industry attaches great importance to. At present, new residential buildings and public buildings are designed and constructed in accordance with the energy-saving standard of 65%. The key promotion in China is the hollow block of silicate concrete exterior wall or the shear exterior wall directly casted by high-rise buildings; The technology itself is mature and reliable, but the following problems still appeared in the p...
