Specification requirements for screw holes of external wall plugs

1. Clean up the sundries in the external wall holes first, and then wet them before construction.

2. When the hole of the external wall is more than 5cm but not more than 10cm, the hardened cement mortar shall be used to block it. If the hole exceeds 10 cm, fine stone concrete should be used for plugging.

3. In addition, ensure the tightness of the plug hole to avoid various problems in future use.

What are the exterior wall decoration materials?

1, the building exterior wall can be decorated with marble and other stone materials, and marble is generally constructed by dry hanging, which has the advantages of high-grade atmosphere and good wind resistance, and is widely used in high-grade residential quarters, hotels and other places. However, the construction technology of dry hanging marble stone on the external wall will be more complicated, the cost will be higher, and there is still a certain risk of marble falling off.

2. Real stone paint is widely used in the field of building exterior walls. Because of its natural stone-like texture and natural color, it is often used to replace dry hanging stone. Real stone paint has the advantages of wide application range, environmental protection, non-toxicity and good pollution resistance. The real stone paint is easy to crack due to the large temperature difference, and the construction is relatively complicated.

3. Glass curtain walls can also be used to decorate the external walls of buildings. Glass curtain wall is light in weight, usually about one-fifth of Dali decorative exterior wall, which can effectively reduce the weight of the building. The glass curtain wall can be designed and used together with other intelligent technologies, and has the advantages of good artistic effect, good wind and earthquake resistance and convenient maintenance. However, the glass curtain wall has poor fire prevention ability and the glass is easy to be damaged.

What should be paid attention to in external wall construction?

1, the outer layer construction, construction must be carried out at a suitable temperature, the sun can't direct construction metope, rainy or snowy days can't construction.

2, winter construction, be sure to give the paint film a dry time, so as to achieve better results. If the surface of paint film cannot be hit or polluted during drying, it will directly affect the appearance of the whole back wall. Due to the low construction temperature in winter, appropriate thermal insulation measures should be taken to prevent the film from freezing, otherwise it will affect the effect after construction.

3, winter construction, putty must be completed on the wall, such as dry before polishing. Polishing before it dries will also lead to uneven walls. And after the completion of the outer layer construction, there should be a curing time of 1 day, which means that the surface of cement mortar should have a certain time to dry. Only in this way can the bottom surface be dry and firm, and the wall is not easy to crack or sand.
