When making clod wash U-shaped steel, steel plate or coil of strip are through the two sides surplus material after specific cutting wire cutting, through rationally designing, this part
Edge inverted trapezoidal jagged edges (trapezoidal groove is equipped between i.e. adjacent inverted trapezoidal jagged edges) and cold roll forming U-shaped steel side
Edge inverted trapezoidal sawtooth is identical.It therefore, can be U-shaped steel by two blocks of this part steel plates and one piece of rectangular steel plates welding production, in addition, In
By comprehensive typesetting, it can be achieved that the peak use rate of material before U-shaped steel production.
Using U-shaped section, combination beam is substantially increased in the stability of construction stage, interim branch is added when avoiding construction
Support, increases the shear resistance of combination beam；In addition, the non-Transducers Embedded in Concrete part in tradition H transfer structure for SRC beams lower part is being built
Need to be wrapped up when building use so as to more attractive, and in the utility model U-shaped cavity with floor placing concrete simultaneously, concrete with
Steel cooperates, and further improves the stabilization and fire resistance property of U-shaped steel web, meanwhile, floor lower part exposes girder steel and is
Rectangular section, building eliminate the cost to girder steel package when in use.
The effect major embodiment that the utility model reaches are as follows:
1) construction stability is good, and girder steel does not need temporary support when pouring floorslab concrete；
2) steel using amount and welding workload are reduced, steel peak use rate is improved；
3) mechanization degree is high, reduces cost of labor；
4) fabrication and installation are simple, and stock utilization is high, convenient to carry out；
5) concrete is filled in, improves girder steel fire resistance property；
6) high with building matching degree, finishing processing is simple.
