Fire-proof thermal insulation wall body poured with thermal insulation layer

Abstract

The invention relates to a fire-proof thermal insulation wall body poured with a thermal insulation layer. The wall body solves the problems of poor thermal insulation property, complicated construction, difficult control on quality safety stability and easy cracking of a surface layer and adopts the technical solution that the fire-proof thermal insulation wall body is formed by building brick bodies with cavities into a single-layer or a double-layer wall body and then pouring a thermal insulation layer on the wall body; the outer wall surfaces are vertically aligned; gaps do not exist in mortar among the brick bodies, which prevents thermal insulation material from outflowing when in pouring the thermal insulation layer; the mortar can not exist in the cavities; when the wall body is built to the height of 0.6m to 3.0, thermal insulation layer pouring is carried out; the thermal insulation materials are poured into the cavities; the thermal insulation layer needs to be poured fullywithout gaps; after the whole wall is built, leveling layers are arranged on the inner surface and the outer surface of the outer wall; after the strength of the leveling layers reaches 0.4MPa, a finishing coat is painted, and then, the fire-proof thermal insulation wall body poured with the thermal insulation layer is formed. The invention not only overcomes the problems of unfirm bond of the outer thermal insulation wall, poor ageing resistance and wind load resistance performance, easy cracking and the like but also reduces construction processes and reduces manufacture cost and also has the advantages of good fireproof performance and waterproofness and can enclose bearing structures.

Description

1. Technical field [0001] The invention relates to the field of construction, in particular to a fire-proof and heat-retaining wall with a perfusion heat-insulation layer. 2. Background technology [0002] With the continuous development of economy and technology, it has become the consensus of people to achieve sustainable and coordinated development. Building energy saving has been paid attention to by many countries because it can greatly reduce energy consumption, reduce environmental pollution and greenhouse effect. The external wall insulation technology is popular because of its advantages of not occupying indoor space. The existing external insulation walls mainly include polystyrene particle slurry, pasted polystyrene board, cast-in-place polystyrene board, rock wool board, foam Glass, poured polyurethane rigid foam and other walls. These walls have different thermal insulation performance, constructability, safety and stability. Some thermal insulation walls use ...

AI Technical Summary

Problems solved by technology

[0003] In view of the above situation, in order to overcome the defects of the prior art, the object of the present invention is to provide a fire-proof and heat-insulating wall with perfusion insulation layer, which can effectively solve the problems of poor heat preservation performance, complicated construction, difficult control of quality, safety and stability, and easy cracking of the surface layer. , the technical solution is that the fire-proof and thermal-insulation wall is formed by masonry of single-layer or double-layer bricks with cavities (also known as blocks, the same below), and pouring the thermal insulation layer. The masonry method is as follows: The outer wall is vertically aligned, and there is no gap in the mortar between the bricks to prevent the insulation material from flowing out when the insulation layer is poured. There must be no mortar in the cavity. If the mortar falls accidentally, it should be removed from the cavity as soon as possible; masonry 0.6 From a height of 3.0 meters to 3.0 meters, the insulation layer is poured, and the insulation material is poured into the cavity. Set a leveling layer on the surface, and after the strength of the leveling layer reaches 0.4mpa, paint the finish layer to form a fireproof and thermal insulation wall with a perfusion insulation layer; the brick body with a cavity has 1 or 2 cavities, The cavity is placed on the left end of the brick body, or the right end, or the front, or the rear, or the left and right ends, or the front and rear (such as Figure 1-Figure 6 As shown), the cavity is connected up and down, with a width of 20mm-60mm, and the distance between the three sides of the cavity wall and the side wall of the block is 0.5mm-25mm, that is, the wall thickness of the cavity is 0.5mm-25mm; The brick body is sintered clay block with or without pores, or fly ash block, or concrete block, etc.; the insulation material is polyurethane, vitrified microbeads, polyphenylene particles, perlite One of thermal insulation materials; the leveling layer is ordinary mortar (that is, mortar, which is made by mixing inorganic cementitious materials, fine aggregate and water, which is a conventional general technology), or anti-seepage Anti-cracking mortar, or in areas with large temperature differences, anti-seepage and anti-cracking mortar is added with mesh cloth for tensile strength or alkali-resistant mesh cloth; the said finishing layer is latex paint, imitation porcelain paint or decorative A kind of facing brick; the said anti-seepage and anti-cracking mortar is a commercially available product produced by Suzhou Changshu City Hecheng Energy-saving Thermal Insulation Material Co., Ltd., Fujian Province Shaxian Huahong Chemical Co., Ltd., Chengdu Qineng Thermal Insulation Material Engineering Co., Ltd.
