Methods of sealing wall holes
When decorating walls, it is common to encounter walls with many large and small holes. It not only affects the decoration effect, but also affects the process of the decoration program. So what should be done when there are holes in the wall? What are the methods of sealing wall holes?
When decorating walls, it is common to encounter walls with many large and small holes. It not only affects the decoration effect, but also affects the process of the decoration program. So what should be done when there are holes in the wall? Wallhole pluggingWhat are the methods?
一、wallhole pluggingMethod of checking the fire-resistant pavement, necessary cable organization before installation, damage to the fireproof packaging, do not use broken fireproof bags, wrap the organic fireproof material around the cable, and then insert the fireproof cover into the gap. Fireproof wrapping must be cross-stacked, and although fireproof wrapping should be used on cable spools, the dimensions of the fire barrier on the spool should be placed in the same hole as the bottom. And the fireproof packaging must be compact for placement. When the fireproof wall consists of fireproof packing, brick support braces should be used at the bottom of the firewall.
二、wallhole pluggingMethod of inorganic fireproofing materials should be constructed in strict accordance with the requirements of the product specification, according to the size of the hole to be sealed, if the hole area is larger than 0.2 meters, the bottom plate must be reinforced with an inorganic spacer. Firewalls should be soft and smooth, making firewalls without edges and burrs, must be in the composition of the barrier barrier frame of the branch cable, so we have to prepare the hole should be set at the bottom of the drainage hole.
三、wallhole pluggingMethod of In order to produce organic fire-resistant film material, organic fire-resistant isolation material must be inserted into the hole in order to be sealed during construction, by winding the cable, according to the design conditions of the organic film of fire-resistant material, be sure to uniformly pack the barrier material organic fire in a high-density, when the closed organic fire-resistant material and the partition is to be placed slightly higher than the separation of the organic fire-resistant material of the partition, the bottom piece needs aluminum alloy Frame, which can be molded into a certain shape. Cables and cable protection tubes are prepared for hole sealing with two ports of closed organic material, with nozzles of 50 mm or more.
四、wallhole pluggingMethod of To create a fire partition, the exterior quality of the partition must be checked before installation, the separator and cable bracket are provided with two pairs of special hook bolt bracket support arms for securely fixing the frame, ensuring the same level as the entire separator parallel to the bracket, the bolt heads should not be exposed too long and should be used with special washers. The connection between the separators should be secured by approximately 50mm knees and bolts with a special washer, most of the installation process gaps and cracks are sealed with organic refractory material.
