For guaranteeing the smooth of appearance, prevent that also cutting edge from appearring in the outside, big two in channel-section steel is one group, the vat steel tank mouth positioned opposite of each group, two big channel-section steels are one group of notch positioned opposite in addition; Channel bar is arranged between two groups of big channel-section steels, and notch is towards the inboard of riser, and the bottom of the bottom of channel bar and big channel-section steel is on same plane.
The side that the end of big channel-section steel does not have the location division is provided with inside flange, and the rivet riveting is on flange, and the location division exceeds flange.The location division exceeds flange and is inserted in the location notch, and the outer surface of flange contacts with the inner surface of riser, by contacting of plane and plane, guarantees the depth of parallelism between two risers.
Because the size of channel bar is smaller, one of them side of channel bar is provided with flange, and the length of flange is greater than the width of channel bar notch, and the location division exceeds flange, and the rivet riveting is on flange, and a rivet is in notch, and another rivet is outside notch.
As preferably, wherein one group of big channel-section steel couples together two channel-section steels with a channel bar near end position, and the width of the height of channel bar and vat steel tank mouth matches, and channel bar extend in the big channel-section steel.Channel bar is an angle steel, one side can with angle steel come the circuit board of gsm system is supported.
As preferably, each riser is provided with three connecting plates, and connecting plate is formed by the bending of riser otch, and respectively is equipped with connecting hole on connecting plate.Connecting plate is used for fixing the branch frame, directly can prevent to handle affairs row welding or boring to the integrally-built influence of minute frame in the lining at riser upper cut and bending, and processing simultaneously is also more convenient, also convenient the installation.
Three in alignment being arranged in the middle of the riser of connecting plate, parallel with the side at channel bar place on the riser.
The beneficial effects of the utility model are: adopt being connected between location division and the location notch, the flange assist location is set on the channel-section steel and carries out rivet and be connected, can improve whole precision, prevent that distortion or deflection from appearring in the branch frame, otch and bending are set on riser form fillet, convenient processing, the convenient installation.
