Abstract
The invention discloses a method for constructing external walls. The method includes steps of 1), arranging pouring formworks on two sides of each shear wall to be poured, and integrally connecting the pouring formworks on the two sides of each shear wall with each other by opposite pull lead screws; 2), pouring concrete between the formworks on the two sides of each shear wall, allowing the poured concrete to be formed to obtain the shear walls, detaching the opposite pull lead screws and the formworks on the two sides of each shear wall and allowing indoor and outdoor through holes to be formed in certain positions of the shear walls; 3), plugging opening ends of the outsides of the holes by rubber plugs; 4), injecting cement mortar or foaming agents in the holes from opening ends of the insides of the holes and enabling the holes to be compactly filled with the cement mortar or the foaming agents; 5), laying bricks to form brick walls between the adjacent shear walls and forming the integral external walls by the brick walls and the shear walls in an enclosed manner; 6), plastering internal wall surfaces of the external walls; 7), plastering external wall surfaces of the external walls. The opposite pull lead screws are detached from the certain positions of the shear walls. The method has the advantages that a process for plugging the holes is easy to operate and can be monitored, waterproof effects can be effectively guaranteed, the later maintenance cost can be saved, and the method has an excellent popularization and application prospect.
Description
Technical field
The invention belongs to external wall construction technical field, particularly relate to a kind of external wall construction method.
Background technology
Usually, external wall is surrounded by shear wall and brick wall, during shear wall construction, first arranges formwork for placing in the shear wall both sides that will build, and with common, by the template of both sides, entirety is connected into wire drawing bar, thus template is reinforced, then start concreting, after concrete construction is shaping, wire drawing bar is removed to the hole left outside throughout chamber, for this kind of hole, once shutoff leakiness, house can leave very large external wall seepage hidden danger after using.Usually, the shutoff mode of this kind of hole has two kinds, and one is by inner slip casting before interior plastering, one is when exterior rendering by outside slip casting, for first kind of way, and the just disposable slip casting in inside before plastering on inner walls, due to the space that outside is unlimited, cannot guarantee that hole is completely filled; For the second way, be all that workman operates on hanging basket when external wall plastering, this mode is due to the bad monitoring of administrative staff, and workman may because lazy or carelessness, and cause hole not by shutoff or shutoff leakiness, quality control difficulty is large.
Summary of the invention
For the deficiencies in the prior art, the object of the invention is to build the holes blocking leakiness that shaping rear dismounting produces wire drawing bar and the external wall seepage hidden danger caused to solve shear wall, a kind of external wall construction hole hermetically-sealed construction is provided, ensures waterproof effect better, save later maintenance expense.
In order to solve the problems of the technologies described above, present invention employs following technical scheme:
A kind of external wall construction method, comprises the steps:
1) formwork for placing is set in the both sides will building shear wall, with to wire drawing bar, the formwork for placing of both sides is connected into entirety;
2) to concreting in the space formed between two side templates, obtain shear wall after concreting is shaping, then remove wire drawing bar and two side templates, now shear wall is removed and hole inside and outside throughout chamber is stayed to the position of wire drawing bar;
3)) select suitable rubber stopper according to the size of hole, before external scaffolding is removed, block with the openend of rubber stopper by hole outside;
4) in hole, cement mortar or blowing agent is injected from the openend of hole inside, holes filling is closely knit;
5) between adjacent shear wall, build brick wall by laying bricks or stones, brick wall and shear wall surround whole exterior wall;
6) inner wall surface of External Wall is plastered, and first clears up metope when plastering, then brushing motar on metope, finally brushing putty on metope again;
7) wall face of External Wall is plastered, and first clears up metope when plastering, and hangs steel fabric sheet at the intersection of shear wall and brick wall, then brushing interfacial agents successively, thermal insulation mortar, anticracking grout, external wall waterproof putty and exterior wall coating material.
Preferably, described is that interior high outer bottom is connected on the formwork for placing of both sides obliquely to wire drawing bar.
Preferably, the end face of described rubber stopper and the wall face of exterior wall concordant.
Preferably, described rubber stopper comprises can insert the columnar part blocked by hole in hole and the openend that can embed hole outside and the end cap part blocked the openend of hole outside from the openend of hole outside, described columnar part and end cap portions are divided and are structure as a whole, and the diameter of columnar part is less than the diameter of end cap part.
Preferably, the columnar part of described rubber stopper is hollow-core construction.
Beneficial effect of the present invention is:
The present invention is after removing wire drawing bar, before external scaffolding is removed, special (purpose) rubber plug (rubber stopper is according to the size Selective type of hole) is adopted to carry out shutoff to the opening portion of hole outside, then before the inner wall surface of External Wall is plastered, the disposable slip casting in hole from the opening portion of hole inside, holes filling is closely knit, this method for blocking has feature that is easy to operate, that can monitor, waterproof effect can be ensured better, save later maintenance expense, there is good popularizing application prospect; The external wall simultaneously adopting construction method of the present invention to obtain has the features such as cracking resistance, insulation, waterproof, the present invention proposes a kind of complete construction method in addition, is conducive to realizing normalized construction.

Fig. 2 is the sealed structural representation of shear wall construction hole of the present invention;
Fig. 3 is the sectional drawing of rubber stopper of the present invention;
Fig. 4 is the A direction view of Fig. 3.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail.
See accompanying drawing, a kind of external wall construction method, comprises the steps:
1) formwork for placing 2 is set in the both sides will building shear wall 1, with to wire drawing bar 3, the formwork for placing 2 of both sides is connected into entirety, template is reinforced;
2) to both sides formwork for placing 2 between concreting, obtain shear wall 1 after concreting is shaping, then remove the formwork for placing 2 to wire drawing bar 3 and both sides successively, now remove on shear wall 1 and hole inside and outside throughout chamber is stayed to the position of wire drawing bar 3;
3)) select suitable rubber stopper 4 according to the size of hole, before external scaffolding is removed, block with the openend of rubber stopper 4 by hole outside;
4) in hole, cement mortar or blowing agent 5 is injected from the openend of hole inside, holes filling is closely knit;
5) between adjacent shear wall 1, build brick wall by laying bricks or stones, brick wall and shear wall 1 surround whole exterior wall;
6) inner wall surface of External Wall is plastered, first metope is cleared up when plastering, then brushing motar on metope, motar normally forms with the proportions of 1:3 according to lime, cement, or form according to the proportions of 1:3:9 according to lime, cement, sand, finally brushing putty on metope again;
7) wall face of External Wall is plastered, first metope is cleared up when plastering, steel fabric sheet is hung at shear wall 1 and the intersection of brick wall, the object hanging steel fabric sheet is to ensure that intersection does not occur crack, ensure globality, increase fixing, then brushing interfacial agents successively, thermal insulation mortar, anticracking grout, external wall waterproof putty and exterior wall coating material.
