Description

The structure of the leak-proof wall body renovated from the old wall

technical field

The utility model relates to the technology in the field of walls, in particular to a leak-proof wall structure for renovation of old walls.

Background technique

In the 1980s, most of the factories and dormitories in various local industrial zones had mosaic walls. In view of many years of wind and rain, some walls have cracked and fallen off and other reasons, there are many factories and dormitories that need to be re-treated and refurbished. However, if the original mosaic is removed, the amount of processing work will be quite large, and the investment cost will be relatively large; large-scale chiseling operations in a factory area that is put into production and has dense workers have great potential safety hazards.

Contents of the invention

In view of this, the utility model aims at the deficiencies in the prior art, and its main purpose is to provide a leak-proof wall structure for renovating old walls, which has the characteristics of simple structure and convenient construction.

In order to achieve the above object, the utility model adopts the following technical solutions:

A leak-proof wall structure for renovating an old wall, comprising an old wall, a first putty layer, an anti-crack grid cloth, a second putty layer, a primer layer, a stone paint layer and a finish paint layer; the first A putty layer is covered on the outer surface of the old wall; the crack-resistant grid cloth is covered on the outer surface of the first putty layer, the second putty layer is covered on the outer surface of the crack-resistant grid cloth, and the primer layer Covering the outer surface of the second putty layer, the stone paint layer covers the outer surface of the primer layer, and the finish paint layer covers the outer surface of the stone paint layer.

Preferably, the crack-resistant mesh cloth is reinforced flexible glass fiber plastic mesh.

Compared with the prior art, the utility model has obvious advantages and beneficial effects. Specifically, it can be known from the above technical solutions:

The original old wall mosaic of the utility model does not need to be eradicated, and the first putty layer, the anti-cracking grid cloth, the second putty layer, the primer layer, the stone paint layer and the overcoat paint layer can be arranged in sequence. The structure is simple and the construction is simple. It is convenient, shortens the construction period, and reduces the construction cost. The wall renovation is novel in color, dustproof and impermeable, more beautiful and practical, and has achieved good application results.

In order to illustrate the structural features and functions of the utility model more clearly, the utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

Description of drawings

Fig. 1 is a sectional view of a preferred embodiment of the present utility model.

Explanation of the accompanying drawings:

10. Old wall 20. First layer of putty

30. Crack-resistant grid cloth 40. The second putty layer

50, primer layer 60, stone paint layer

70. Finish paint layer.

detailed description

Please refer to shown in Fig. 1, it has shown the concrete structure of the preferred embodiment of the present utility model, comprises old wall 10, the first putty layer 20, crack-resistant grid cloth 30, the second putty layer 40, primer layer 50 , stone paint layer 60 and finish paint layer 70 .

The first putty layer 20 is covered on the outer surface of the old wall 10; the crack-resistant grid cloth 30 is covered on the outer surface of the first putty layer 20, and the crack-resistant grid cloth 30 is a reinforced flexible glass fiber plastic net , the second putty layer 40 is covered on the outer surface of the crack-resistant grid cloth 30, the primer layer 50 is covered on the outer surface of the second putty layer 40, and the stone paint layer 60 is covered on the outer surface of the primer layer 50 On the surface, the finish paint layer 70 covers the outer surface of the stone paint layer 60 .

During production, firstly, scrape the putty for the first time on the outer surface of the old wall 10 to form the first putty layer 20, so as to repair the old wall 10, scrape the putty for leveling, and then paste the anti-crack grid to prevent the wall surface from cracking Cloth 30, and then scrape the putty for the second time to form the second putty layer 40. After the second putty is scraped for 12 hours, polish the wall with No. 320 water sandpaper. The wall is polished, requiring no knife marks on the wall, Yin and Yang The corners are straight and free of burrs. After polishing, rinse the wall with clean water to remove dust thoroughly. After the wall surface alkalinity and moisture content are tested and qualified, carry out wall surface subdivision primer construction to form primer layer 50; 8kg, the spraying tool is to use a special spray bucket for construction. After the sealing primer is completely dry, spray one or two coats of stone paint, and the interval between the two coats of spraying should not be less than 4 hours. During spraying construction, the distance between the spray gun and the object to be coated should be 30-50cm, and the stone paint should be evenly sprayed on the wall surface with force. After spraying, let it dry to form the stone paint layer 60, then, coat the finish paint to form the finish paint layer 70, the finish paint adopts a good quality short-haired roller to brush, and the brushing should be coated with a grid to avoid If there are obvious scratches in the finish paint, the finish paint must be diluted strictly according to the proportion, and excessive dilution is not allowed. Paint from bottom to top, and the window is protected by split line isolation.

The key point of the design of the utility model is: the original old wall mosaic of the utility model does not need to be eradicated, and the first putty layer, the anti-cracking grid cloth, the second putty layer, the primer layer, the stone paint layer and the overcoat paint are arranged in sequence Only one layer is enough, the structure is simple, the construction is convenient, the construction period is shortened, and the construction cost is reduced. The wall renovation is novel in color, dustproof and impermeable, more beautiful and practical, and has achieved good application results.

The technical principles of the present utility model have been described above in conjunction with specific embodiments. These descriptions are only for explaining the principle of the utility model, and cannot be construed as limiting the protection scope of the utility model in any way. Based on the explanations herein, those skilled in the art can think of other specific implementations of the present utility model without creative work, and these forms will all fall within the protection scope of the present utility model.
