How to correctly handle the hidden dangers of engineering home improvement

To make such a complex ceiling safe, ordinary nails and plastic plugs are not reliable, solid keels are indispensable. The glass entrance is best secured with a frame. When the lower tank is fixed, it is recommended that there must be a lower frame or a wooden table to prevent the collision.

fireplace

● Hidden dangers: The fireplace on the wall collapses or falls off

● Hidden cause: If the place where the fireplace is connected with the wall is a putty, it will take a long time to become powdered and lose its function, so that the fireplace that is glued on the putty will fall off easily.

During installation, if the ground is tilted outwards for a long time, it will collapse. If the ground is high and the wall is low, the fireplace tilts towards the wall and the chance of collapse is much lower.

● Correct handling

The decorative fireplace is relatively heavy. The best way is to use a pendant to connect the wall with the side panels. Can also be used side panels and walls with stone special glue together, but this time the wall must be the original concrete wall surface, wall putty powder or light wall can not be directly glued. Lightweight wall fireplaces are best used with bolts longer than 5 cm to connect the fireplace to the wall. Prefabricated wall or hollow brick wall, inside must use embedded parts such as wood to fill and fix the empty place, and then bolt the fireplace. If the wall cannot be loaded with embedded parts, cover the entire wall and then use the pendant.

Marble decoration

● Hidden danger: Marble material falls off the wall

● Hidden cause: Directly glued and glued on the wall, the plastic is easy to age, causing marble to fall off the wall.

● Correct handling

Marble wall treatment generally has three ways:

The first is dry hanging. Fix it on the wall with bolts. Then, a slot is made in a piece of stone, and the stone is fixed by a T-shaped frame, and the T-shaped frame and the bolt are fixed together. Such a marble wall has a certain distance from the wall itself, but the fixing is good.

The second is wet stickers. It is necessary to apply a layer of steel mesh on the wall first, and then use concrete wet plaster.

The third is to paste directly. Generally divided into paste and paste. The surface-mount method is suitable for thin stone, the thickness is below 8mm, the weight is similar to the wall tile, and it can be pasted with special mortar. Point paste is the use of special glue for stone, the range of points can not be greater than 25CM, the amount of points can not be less than 3-4CM, the thickness of viscose is more than 0.5CM, this way is used for slightly thicker stone.

It is also important to paste directly on the wall surface. First, if there is putty on the concrete wall, you must scrape the putty off and stick it directly on the concrete wall. In addition, because of the large deformation of the light wall, if the wall is deformed after viscose, marble will also change, causing hidden dangers.

The direct paste method is not suitable for the bathroom, because the bathroom is dominated by light walls, and the degree of deformation is large, and the bathroom is often wet. Over time, the plastic is prone to aging and is prone to accidents.

Wooden floor on the wall top

●Easily hidden dangers: falling off

● Hidden cause: The board was not fixed on the surface with bolts and it was pasted directly.

● Correct handling: On the top or wall surface, lay the keel and nail the wood floor and keel together to increase the firmness.

Brick wall

● Hidden dangers: bricks fall off the wall

● Hidden cause: Bricks are heavy and large, easy to sink when affixed, together with the use of cement mortar itself is easy to slide, resulting in the probability of empty drums after paving higher than the wall tiles, resulting in deformation and shedding, in addition to climate change is also caused by the tiles empty drum off The important reason. If the wall of the light wall itself is easily deformed, the large brick has a higher chance of hollowing.

● Correct handling: If it is a concrete wall, it can be pasted, but it is more difficult to paste, so it is best not to use floor tiles in the walls at home.

● Hidden dangers: shedding

● Hidden cause: Only use quick-adhesive powder to stick gypsum decoration. Quick-stick powder + water + glue for a long time, easy to aging, cause shedding.

● Correct handling: Small plaster lines can be glued to the wall with quick-stick powder, but plaster lines and decorations larger than 15 cm must be drilled on the wall, glued with fast glue, and then fastened with screws. . Large gypsum decorations, such as European carved, are best secured to the wall with metal hangers.
