Description
Technical field
The utility model relates to a kind of bracing frame of construction steel structure assembly unit engineering.
Background technology
The steel truss assembly unit of winding up belongs to work high above the ground, and work progress high and medium location assembly unit difficulty is big, and construction technology mainly is by setting up A-frame (seeing accompanying drawing 1), wind up by many covers A-frame sub-truss, the auxiliary girder location at present; But because A-frame is a two-dimensional structure, self stability is poor, so need drawknot between support and the support, to guarantee to form stabilization element, set spacing can not be excessive simultaneously, otherwise unstability appears in pull bar between support easily; This has increased the steel using amount in the engineering undoubtedly, has increased the difficulty of construction of engineering, has increased the construction cost of engineering.
The utility model content
Utility model provides a kind of solid and formula steel truss assembly unit bracing frame, solve existing bracing frame instability, and the engineering steel amount is big, the technical problem of working security difference.
The technical scheme that its technical problem that solves the utility model adopts is:
This solid and formula steel truss assembly unit bracing frame, it is characterized in that: this bracing frame is solid and font structure, the two pairs of vertical rods before and after comprising, be connected to the parallel and lower edge moulding bed bar put of two of two column roots, be connected to the parallel and joist that winds up put of two of two column tops, be connected in two wind up between the joist operating platform and be connected in pull bar between the two pairs of vertical rods in front and back, described operating platform middle part has locating hole, and the edge of locating hole is connected with the locating piece that is used to control the steel truss axial location.
Above-mentioned locating piece can be positioned at the middle part of the joist that winds up, and two wind up the locating piece of four symmetries on the joist.
About the aforesaid operations platform can be divided into two, two operating platforms laterally are connected the column outside respectively.
A pull bar can respectively be arranged at middle part and top between the two pairs of vertical rods in above-mentioned front and back.
Lower edge moulding bed bar, the joist that winds up, vertical rod and pull bar can be H shaped steel or i iron.
The beneficial effects of the utility model are as follows:
And formula bracing frame shape such as its word by the moulding of several shaped steel assembly weldings, are arranged in the butt joint node place of structure, can adjust rod member height and cross section specification according to the height and the weight of structure.The constructor controls installation accuracy by locating piece, winds up in place by the auxiliary steel truss of the operating platform at moulding bed top.After steel truss was in place, member can break off relations, and had improved the efficient of lifting operation; Especially hang time manyly in structure, under the few situation of hanging device, and formula steel truss assembly unit support technology can improve the lifting efficient of loop wheel machine greatly, satisfies daily demand of hanging time.Because bracing frame is a three-dimensional structure, so its stability will be higher than the A-frame of two-dimensional structure far away; Each bracing frame itself is exactly a stable cell cube, satisfies in rod member rigidity under the condition of self amount of deflection, only arranges in joint, rod member two ends to get final product.Save rolled steel dosage to greatest extent, controlled the construction cost of engineering, and be easy to construction.
And formula steel truss assembly unit support technology has solved location, steel member high-altitude, packing problem, provides a more safe and reliable platform for lining for the constructor in work high above the ground simultaneously.Can be widely used in the steel structure assembling construction field.
