First, the fire tube bracket generally adopts angle steel, and the finished bracket needs to be brushed with antirust paint.
Second, there are two styles of fire support according to different installation positions, namely U-shaped support and L-shaped support. U-shaped support, also known as anti-sway support, is widely used in pipes above DN 100. The following is the schematic diagram of the on-site installation of the fire pipe support.
Three, the installation height and spacing of fire pipe support, should be formulated according to the design requirements and fire code.
Four, the size and shape of the fire pipe bracket should be formulated according to the situation of the construction site, pay attention to the larger the pipe diameter, the greater the angle iron used.
Five, it is forbidden to use gas welding in the fire pipe bracket hole, aperture ratio screw diameter is1-2 mm..
Six, when making brackets, the sharp part of the cut should be polished and smooth to prevent harm to the human body.
Seven, fire pipe bracket installed on the beam, the position of the expansion bolt should be above the center line of the beam.
Eight, the maximum allowable spacing of fire pipeline supports and hangers is mainly determined by the vertical load, which should meet the strength and stiffness conditions.
Nine, large-diameter fire pipeline valves need to be supported by independent installation brackets, and cannot be supported by pipeline brackets.
Ten, fire pipe bracket, hanger installation position, should not interfere with the sprinkler spraying effect.
