The purpose of the invention is realized as follows: the utility model provides a steel construction building prevents outer wall structure that ftractures, includes the ALC wallboard, and ALC wallboard surface is equipped with embedded wire net cement layer, plaster layer, first anti mortar layer, extrusion molding insulation board layer, the anti mortar layer that ftractures of second, putty layer and dope layer from inside to outside in proper order, and first anti mortar layer and the anti mortar layer surface that ftractures of second are all impressed and are had alkali-resisting net cloth.
According to the anti-cracking outer wall structure of the steel structure building, the steel wire mesh is embedded in the cement layer, so that the adhesive force of cement mortar and a wall body is improved, and the possibility of plastering layer cracks caused by thermal expansion and cold contraction is reduced; alkali-resistant mesh cloth is pressed into the first anti-cracking mortar layer and the second anti-cracking mortar layer, so that the cracking probability of the wall is further reduced; and press from both sides between first anti mortar layer, the second anti mortar layer of splitting and be equipped with flexible extrusion molding heated board, follow-up deformation between the adjacent outer wall interlaminar can effectively be released, and the wall body crackle appears in effective control. In conclusion, the anti-cracking outer wall structure of the steel structure building has good heat preservation, heat insulation, water resistance and anti-cracking performance.
As a further improvement of the invention, the outer surface of the ALC wallboard is brushed with a waterproof interface agent, so that the waterproof performance of the outer wall is further improved, and the service life of the building is prolonged.
As a further improvement of the invention, the ALC wallboard is vertically assembled, alkali-resistant gridding cloth is pasted on the outer surface of the joint of the ALC wallboard and the outer surface of the connecting position of the ALC wallboard and the floor board, so that the possibility of cracks at the joint of the wall body is further reduced, in addition, compared with the horizontal installation, the ALC wallboard is vertically installed, the formed horizontal board joints are less, and the horizontal board joints are easy to store water and leak, so the water seepage risk of the wallboard can be effectively reduced by the vertical installation of the ALC wallboard, and the installation difficulty of the wallboard is greatly reduced.
As a further improvement of the invention, the plastering layer comprises a first plastering layer and a second plastering layer, and the thickness of the first plastering layer and the second plastering layer is less than 10mm, so that the possibility of hollowing, cracking and leakage of the plastering layer is effectively reduced.
As a further improvement of the invention, the thickness of the first plastering layer is 9mm, the thickness of the second plastering layer is 6mm, the thickness of the first anti-cracking mortar layer is 8mm, the thickness of the extrusion molding insulation board is 30mm, and the thickness of the second anti-cracking mortar layer is 8mm, so that the optimal heat preservation, heat insulation and anti-cracking effects are achieved.
As a further improvement of the invention, the waterproof mixed mortar with the strength grade of M7.5 is adopted in the plastering layer, so that the strength and the expansion coefficient of the plastering layer are basically equivalent to those of the base layer, and the cracks caused by drying and shrinking of the plastering layer are reduced.

Fig. 1 is a schematic view of a crack prevention outer wall structure of a steel structure building according to the present invention.
Fig. 2 is a cross-sectional view taken along line P-P in fig. 1.
Wherein, 1ALC wallboard, 2 embedded wire net cement layers, 3 first plastering layers, 4 second plastering layers, 5 first anti-crack mortar layers, 6 extrusion molding heat preservation plate layers, 7 second anti-crack mortar layers, 8 putty layers, 9 dope layers, 10 floor plates.
Detailed Description
As shown in fig. 1-2 steel construction building anti-cracking outer wall structure, including ALC wallboard 1, 1 surface of ALC wallboard is equipped with embedded wire net cement layer 2 from inside to outside in proper order, first plaster layer 3, second plaster layer 4, first anti mortar layer 5 that splits, extrusion molding insulation board layer 6, second anti mortar layer 7, putty layer 8 and dope layer 9, and first anti mortar layer 5 and second anti mortar layer 7 surface have all been impressed alkali-resisting net cloth.
As shown in FIG. 1, the ALC wallboard 1 is vertically assembled, i.e. the length-direction side of the ALC wallboard 1 is vertical, and the width-direction side is horizontal. Compared with the transverse installation, the vertical assembling has the advantages that the transverse plate joints formed by vertical assembling are few, and the transverse plate joints are easy to store water and leak, so that the water seepage risk of the wall plate can be effectively reduced by vertical installation of the ALC wall plate 1, and the installation difficulty of the wall plate is greatly reduced.
In order to further improve the waterproof performance of the outer wall and reduce wall cracks, two layers of waterproof interface agents are brushed on the outer surface of the cleaned ALC wallboard 1 before formal construction, and then alkali-resistant gridding cloth is pasted on the outer surface of the joint of the ALC wallboard 1 and the outer surface of the joint position of the ALC wallboard 1 and the floor slab 10.
