How to construct and install fire-fighting equipment

Construction and installation of fire-fighting equipment. Indoor fire-fighting water supply system is currently the most common and most important fire-fighting facility installed in buildings, and it plays a pivotal role in extinguishing building fires. Indoor fire-fighting equipment is an important part of the indoor fire-fighting water supply system. The quality of installation and maintenance directly affects the fire-fighting function of the fire-fighting water supply system. Therefore, it should attract the attention of the majority of construction and building users.

　　Construction and installation of indoor fire fighting equipment

　　 There are three methods for installing indoor fire fighting equipment and fire fighting equipment boxes: exposed installation, concealed installation and semi-concealed installation. The fire hose in the box is divided into two types: roll type and hanging type. The following issues should be paid attention to during construction and installation:

　　 1. Indoor fire-fighting equipment should generally be installed in a place where the temperature of the room is higher than 5℃. When it is necessary to install it in a building where there is no suction or freezing, appropriate anti-freezing measures should be taken.

　　2, the fire-fighting equipment water supply pipe can be connected from the back, bottom or side of the fire-fighting equipment box according to specific conditions. The center position of the water supply pipe should be as accurate as possible. If the error is large, it can be solved by adjusting the position of the fire-fighting equipment box.

3. When concealed or semi-concealed installation of fire-fighting equipment boxes, the size of the box holes reserved on the wall should be at least 10mm larger on each side than the outer dimensions of the fire bolt box. For concealed and semi-concealed installations, anchor bolts should be used to fix the fire-fighting equipment box. s position. 

　　4. Anti-rust and anti-corrosion measures should be taken for the connecting part of fire-fighting equipment and the wall, such as applying hot asphalt, stuffing moisture-proof materials, etc.

　　 5. Fire-fighting equipment with front and rear doors should not be installed on the firewall.

　　6. The installation height of the fire-fighting equipment port from the ground is 1.2m, and the water outlet forms an angle of 900 with the installation wall.

　　 7. The length of the fire hose is selected according to the design needs, but the longest should not exceed 25m.

　　 8. When the external electrical circuit passes through the wall of the box, rubber wire gaskets should be used, and the drain hole at the bottom of the box should not be blocked during installation.
