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 fully without 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

Fire-proof thermal insulation wall body poured with thermal insulation layer
One, technical field
The present invention relates to building field, particularly a kind of fire-proof thermal insulation wall body poured with thermal insulation layer.
Two, background technology
Along with continuous development economic and technology, realize that continuable coordinated development has become people's common recognition.Building energy conservation can significantly reduce energy consumption because of it, reduces environment pollution and greenhouse effect, has received the attention of a lot of countries.External Walls Heating Insulation is not owing to take advantage such as the interior space, and popular to people deeply, existing external heat insulating wall mainly contains the granular polystyrene slurry, pastes bodies of wall such as polyphenyl plate, on-site casting polyphenyl plate, rock cotton board, foam glass, pouring polyurethane foam.The heat-insulating property of these bodies of wall, application property, security and stability are different; The employed material thermal conductivity of the heat-preserving wall that has is higher, is not suitable for the needs of severe cold area heat preservation energy-saving, and is wayward in the security and stability construction that has; The complicated quality control difficulty of the construction that has is big; The surface layer cracking resistance problem that has is difficult to resolve determines, and adds that insulation layer places the outside of space enclosing structure, will suffer rain, snow, strong wind unavoidably, freezes, melts, does, wet; The destruction of pernicious gas and ultraviolet ray etc., recent unsticking hollowing, the surface layer problems of crack of also often seeing external thermal insulation.At present; The external thermal insulated wall of processing with hard polyurethane foam; Possessing many functions such as insulation, waterproof, sound insulation, absorbing because of it uses comparatively extensive in the building heat preservation field; On-the-spot directly foaming hard polyurethane foams is applied to the vertical body of wall of outer insulation of finish coat, a main difficult problem such as have that surface finish is difficult to control, poor adhesive force, outside finish between finish coat and the hard polyurethane foams are easy to crack.Along with the propelling in epoch, the development of technology is had higher requirement to space enclosing structure, and exterior-wall heat insulation has been proposed fireproof heat insulating and has been easy to construction, and cheap requirement is satisfied demands of social development to seek a kind of Full Featured space enclosing structure.
Three, summary of the invention
To above-mentioned situation, for overcoming the prior art defective, the present invention's purpose just provides a kind of fire-proof thermal insulation wall body poured with thermal insulation layer, can solve effectively that heat-insulating property is poor, construction is complicated, quality safety is stable wayward; The problem that surface layer is easy to crack, the technical scheme of its solution are that this fireproof heat-preserving wall is (to claim building block again by the brick body of band cavity; As follows) build into individual layer or bilayer by laying bricks or stones, the perfusion insulation layer constitutes, and its building method is; Tight in the wall face vertical alignment, the mortar between the brick body, heat insulating material outflow when preventing to pour into insulation layer; In the cavity mortar can not be arranged, drop, should in cavity, remove as early as possible as mortar is arranged accidentally; Build 0.6 meter to 3.0 meters height by laying bricks or stones, carry out the insulation layer perfusion, in cavity, pour into heat insulating material, full tight is wanted in the insulation layer perfusion, promptly forms the perfusion heat preserving exterior wall; After treating that the full wafer wall is built completion by laying bricks or stones, establish leveling layer, after the intensity of treating leveling layer reaches 0.4mpa, whitewash finish coat again on the inside and outside surface of exterior wall, fire-proof thermal insulation wall body poured with thermal insulation layer; The brick body of said band cavity, its cavity have 1 or 2, and cavity places the left end of brick body; Or right-hand member, or anterior, or the rear portion; Or right ends, or on the front and rear part (like Fig. 1-shown in Figure 6), cavity goes to upper and lower connected state; Wide is 20mm-60mm, and the three limits chamber wall of cavity and the distance of building block sidewall are that the wall thickness of cavity is 0.5mm-25mm for 0.5mm-25mm; Said brick body is the clay building block of the porose or atresia of sintering, or fly ash building block, or concrete block etc.; Said heat insulating material is a kind of in the heat preserving and insulating materials such as polyurethane, glass bead, granular polystyrene, perlite; Said leveling layer is that the ordinary mortar of brushing (is a mortar; Be to mix and stir by inorganic coagulation material and fine aggregate and water to form, be conventional current techique), or the seepage control and crack resistance mortar; Or, add the grid cloth that is useful on tension or alkaline-resisting grid cloth in the seepage control and crack resistance mortar in temperature difference larger area; Said finish coat is a kind of of emulsion paint coating, imitation porcelain coating or face brick; Said seepage control and crack resistance mortar is Changshu City, Suzhou and the commercially available prod that becomes energy-saving and heat-insulating material Co., Ltd, Sha County, Fujian Province China great chemical industry Co., Ltd, Chengdu neat ability heat insulating material Engineering Co., Ltd etc. to produce.Problems such as the present invention not only overcomes not firm, anti-aging, the Wind-Pressure Resistance ability of external thermal insulated wall bonding, and is easy to crack have also reduced working procedure and have reduced cost, and the present invention also has fire prevention, water resistance and well has the advantage that can go along with sb. to guard him load-bearing concurrently.
