Large-span fast-assembly inclined leg frame type support

Abstract

The invention discloses a large-span fast-assembled inclined leg frame type support. The support comprises steel stand columns, bailey pieces, double 40d I-beams, connecting steel pipes, flange plates, steel pipe shear supports, 630 steel pipe supporting rods, auxiliary supporting legs, triangular inclined leg frames, double 40d I-beam column feet, adjusting section stand columns, threaded pull rods, bowl buckle frames, connecting steel channels, steel channel shear supports, 529 steel pipes, connecting steel pipe supports, 630 steel pipes and I-steel; The support is advantaged in that in order to facilitate on-site mounting and dismounting construction, the whole bracket is designed into a modular frame structure, the bottom section is a triangular inclined leg frame, all the sections arestandard frame sections, and the modules are connected in a bolted manner, so the support is convenient to dismount. According to the longitudinal stress system, the number of 321 type bailey beams is increased for spanning construction, and a layer of bowl buckle support is additionally arranged on each bailey beam, so a problem that modular design height adjustment is inconvenient is solved.

Description

Technical field [0001] The present invention relates to a framework bracket, specifically a large span rack assembled torque leg frame, belonging to the technical field of building construction bracket system. Background technique [0002] Currently, the boom beam is widely used by the beam column stent method. The standard span bracket vertical force system is longitudinally equipped with four-row of steel columns, and the side-raised steel column is supported on the bridge block, and the middle steel column is supported in the foundation On the basis of the expansion of the treatment, on the basis of the steel pipe, it is necessary to perform foundation processing, resulting in an increase in construction cost, and cannot ensure energy saving and environmental protection; and the stent is slow, extended during the period; increase the bracket, demolition of high-altitude work, Has a large security risk; and cannot avoid cross-circuit, cross rivers, cross-tube lines, etc. The im...

Problems solved by technology

[0002] Cast-in-place box girders are widely constructed using the beam-column support method. The traditional method for the vertical stress system of the standard span support is to erect four rows of steel columns vertically, the side row of steel columns are supported on the bridge cap, and the middle row of steel columns is supported on the foundation. However, during construction, foundation treatment is required, which increases construction costs and cannot ensure energy conservation and environmental protection; and the erection of supports is slow, prolonging the construction period; increasing the amount of overhead work for erecting and removing supports, It has a greater safety risk; and it is impossible to avoid the impact of complex environments such as crossing roads, rivers, and pipelines on construction
