Fire riser bracket specification selection

Hello, in fact, counting the bracket is a construction experience, pipe different connection methods, different installation locations, then the style of the bracket will be different, the installation spacing is also different, I'll give you a general introduction.

1, the style of the bracket: the main style of the bracket has a "door" type or "U" bracket, also known as anti-shaking bracket (mostly used in DN100 and above pipe diameter), "L" type or "angle ruler "bracket (mostly used in small pipe diameter and wall risers).

2, the spacing of the bracket: the maximum spacing of the bracket is a specification, this you can Baidu, but the actual installation of the bracket spacing than the specification to be smaller, flange connection, threaded connection when the bracket spacing than the groove connection. Fire in the most common groove as an example: DN65 ~ DN150 bracket spacing is generally in the 4 ~ 4.5 meters (bracket spacing set up with the span of the beam, because the bracket is often attached to the edge of the beam installation), DN25 ~ DN50 bracket spacing is generally in the 3 ~ 3.5 meters.

3, bracket selection: single DN100, single DN150 pipe will generally choose 5 # angle or 5 # channel or 6 # channel; two *** with the bracket will choose 8 # or 10 # channel; three pipe *** with the choice of 10 # or 12 # channel; DN50 ~ DN80 in the sprinkler in a small amount of DN65 in the hydrant in a larger amount of general 5 # angle to consider; DN25 ~ DN50 in a small amount of DN65 in the hydrant in the hydrant in the amount of 5 # angle to consider; DN25 ~ DN80 in the sprinkler in the amount of DN25 ~ DN50 in the hydrant in the amount of 5 # angle to consider; DN25 ~ DN50 in the hydrant in the amount of DN25 in the hydrant in the amount of 5 # angle to choose Angle consideration; DN25~DN40 generally 3# or 4# angle consideration.

4, stent calculation: stent calculation boom length is indeed the key, so to determine the elevation of the pipeline and the floor bottom elevation (because the fire pipe is generally installed according to the bottom of the beam, so the beam height is very critical), the general basement stent boom longer, slightly shorter in the floor.

So the sprinkler bracket roughly estimated: 150 100 pipe according to 5 # channel spacing 4.5 meters, "U" bracket, a single bracket with 1.5 meters, 80 65 50 pipe according to 5 # angle spacing 4.5 meters, "U" bracket, a single bracket with 1.5 meters. U-shaped bracket, a single bracket with material 1.5 meters, 40 32 25 pipe according to 4 # angle spacing 3.5 meters, "L" bracket, a single bracket with material 1.2 meters! Please adopt
