The aerated concrete building blocks are arranged on the periphery of the wall body, heat insulating slurry is smeared on the outer concrete surfaces of the boundary beam and the boundary column, the heat insulating mortar is smeared on the surfaces of the beam and the column layer by layer, the anti-crack net and the anti-crack mortar are fully hung on the outer wall, and the structural reliability and long-term weather resistance of the outer heat insulation of the outer wall are greatly improved.

Description

The air-entrained concrete building block insulated wall

Technical field

The utility model relates to a kind of exterior wall that is applicable to the reinforced concrete frame structure building, and the utility model relates to a kind of concrete block wall structure in particular.

Background technology

In recent years, along with applying of building energy conservation, heat insulating material is extensive use of in construction work.In many new homes, all the New-type heat insulating walling that has insulation layer can be arranged at the moment.Heat-preserving wall has plenty of and is made of expanded perlite and expanded polystyrene (EPS) light weight concrete construction, profile is rectangular facade body, former and later two exposed faces are arranged, there is semicircle or the semiellipse groove along the central axis opening on the surface up and down, and four roads are along the mutual vertical connection of the groove on surface.The building masonry wall that this member is built by laying bricks or stones, inside are formed with the duct that is interconnected of level and vertical composition, and fluid concrete constitutes an integral body in the duct.Having plenty of dual-side in block body, oppositely to be provided with the cross section be half groove of through hole cross section, after building block becomes wall, through hole from the foot of a wall to the wall top is always arranged, with cement mortar filling part or whole through hole, and in through hole, insert reinforcing bar, form reinforced concrete post, constitute steel concrete thermal insulation wall.This type of body of wall is easy to occur the difficult problem that the Virgin's milk shellac varnish splits very much in decorations.It is because slight crack appears in the cement of body of wall that this kind splits, or the slit of body of wall " warming plate " splits and form, and is the architectural shortcoming that can't overcome.These bodies of wall of prior art generally adopt sheet material, slurry, piece material and expect the external thermal insulation of combined wall board as exterior wall, and the bonding reliability of the long-term weatherability that this body of wall weak point is the external wall outer insulation engineering, the reliability that is connected with structure and insulation layer and decoration of exterior wall layer is difficult to resolve determines.And construction period is longer, and cost is higher.

Summary of the invention

The task of utility model provides a kind ofly can save the most of insulation layer of exterior wall, and can improve external heat preserving structure for exterior wall reliability and long-term weather resisteant, the air-entrained concrete building block insulated wall that cost is lower.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of air-entrained concrete building block insulated wall, comprise, outer-wall building air-entrained concrete building block masonry metope, it is characterized in that, the outer brick work air-entrained concrete building block metope of body of wall, be coated with heat preservation slurry at side bar, side column outside concrete surface, air-entrained concrete building block is the fissure of displacement up and down, lap length is not less than 1/3 of building block length, and be not less than 150mm, exterior wall is completely hung anti-crack net and is coated with concavo-convex anticracking grout layer, and air-entrained concrete building block wall and structure wall column junction are provided with tension rib.

The utility model has following beneficial effect than prior art.

The utility model utilizes the own heat-insulating property of air-entrained concrete building block itself, does not do insulation layer in wall outer side, only partly adds at heat bridge and does insulation layer.Completely hang anti-crack net, improved the globality that outer surface of wall is plastered.Adopt the double exterior-wall heat insulation of doing of air-entrained concrete building block, only use heat preservation slurry, solve the heat bridge effect of air-entrained concrete building block and concrete intersection, can guarantee the energy-conservation quality of engineering at building outer concrete beam, post.

Speed of application is fast.Saved the operation of specializing in insulation layer at the big face of exterior wall, only smeared heat preservation slurry in side bar, part, the side column outside.Owing to saved the most of insulation layer of exterior wall, saved engineering cost.Through measuring and calculating relatively, adopt the double exterior-wall heat insulation of doing of air-entrained concrete building block to be the cheap about 16 yuan/m2 of thermal insulation mortar outward, saved construction cost greatly than the general light-weight walling material of employing.Practical application proves that larger area hollowing and cracking are not found in wall plastering, and the plastering quality of wall face improves greatly.

Brick work air-entrained concrete building block wall outside body of wall, side bar, side column outside concrete surface are smeared heat preservation slurry, thermal insulation mortar is smeared in beam, cylinder layering, completely hang anti-crack net at exterior wall, smear anticracking grout, both improve the construction quality that the wall body outer wall facing is plastered, improved the structural reliability and the long-term weather resisteant of external wall outer insulation again greatly.Bonding firmly between each floated coat and between floated coat and the matrix, no delamination, hollowing, surface layer do not have defectives such as quick-fried ash and crack.

Owing to saved the operation of specializing in insulation layer at the big face of exterior wall, only smear heat preservation slurry in side bar, part, the side column outside, so the quickening of the speed of application of external wall plastering, saved the construction period.
