Description

Steel structure supporting truss with torsion resistance function Technical Field The invention relates to the technical field of steel structure support trusses, in particular to a steel structure support truss with torsion resistance. Background The steel structure supporting truss is made of steel, and has a quite wide application range, for example, in roofs (roof trusses and the like) and crane girders (namely crane trusses) of industrial and civil buildings, bridges, cranes (towers, beams or arm bars and the like), hydraulic gates and ocean oil extraction platforms, the steel truss is commonly used as a main component of a bearing structure, various types of steel net frames which are commonly used in large-span public building roof structures belong to space steel trusses, various types of towers, such as towers for televisions, power transmission, drilling and crane and mast towers, and space steel trusses formed by three-face, four-face or multi-face plane trusses are commonly used. In the single-story factory building steel skeleton, the roof steel truss often forms single span or multi-span rigid frame with the steel column, and horizontal rigidity is great, can better adapt to great crane or vibration load's requirement, in the current roof steel truss structure, adopts bolt fixed connection or welded mode to assemble between steel truss and the steel column generally, no matter bolted connection or welding, need carry out standard judgement to the length of steel truss to and then fix a position the punching, guarantee the stable connection between steel truss and the steel column, and the mode of vertical positioning connection who adopts between the two makes the steel structure have the function of anti torsion. However, this type of steel structure truss, just like the above, when carrying out bolted connection, need guarantee that the mounting hole of steel column and steel truss must correspond, and the length of steel truss is unadjustable, must the sizing cut, and when installing in actual scene, because the cement base position skew of bottom, lead to the steel column mounted position to take place the skew, and then make the connecting hole dislocation phenomenon between steel column and the steel truss compare and be, and then lead to on-the-spot constructor to consume a large amount of time to carry out the regulation, can't realize quick installation's function, when current steel truss span is great, need adopt two sets of steel trusses and more to splice the mode to extend, and current splice mode mostly adopts two splint centre gripping at the inboard both ends of steel truss, and connect through the bolt, sometimes for the stability of junction structure, can be provided with the triangle-shaped support of falling in the bottom of junction, and then strengthen the junction, but this type mosaic structure for the bottom of steel truss need avoid the triangle-shaped support of bottom when installing other mechanical parts, and then influence the assembly of follow-up mechanical parts. Disclosure of Invention The invention aims to provide a steel structure support truss with an anti-torsion function, so as to solve the related problems that the existing steel structure support truss provided in the background art is inconvenient to install quickly and the connection structure is not optimized enough. The I-shaped beam A and the I-shaped beam B are spliced on one sides, close to each other, of the tops of the two groups of the mounting bases, a positioning adjusting connecting member is jointly arranged between one end, close to the I-shaped support column, of the I-shaped beam A and the I-shaped beam B, the positioning adjusting connecting member is used for positioning and adjusting connection of the I-shaped beam A and the I-shaped beam B with the I-shaped support column, a supporting connecting member is jointly arranged at one end, close to each other, of the I-shaped beam A and the I-shaped beam B, and the supporting connecting member is used for bolting the I-shaped beam A and the I-shaped beam B. Preferably, the positioning adjustment connecting member comprises two groups of fixing clamping plates welded on the inner side of the top of the I-shaped support column, one end of the I-shaped beam A is inserted between the two groups of fixing clamping plates, six groups of adjustment connecting through holes are formed in the two ends of the fixing clamping plates in a penetrating mode, four groups of movable clamping plates are symmetrically arranged at one ends, away from each other, of the fixing clamping plates, mounting bolts A penetrating through the movable clamping plates, the fixing clamping plates, the adjustment connecting through holes and the I-shaped beam A are jointly arranged at one ends, away from each other, of the movable clamping plates, adjusting bolts penetrating through the I-shaped support column are arranged at one side, close to the I-shaped support c
