Supporting bracket with fixing function for road and bridge building construction

Abstract

The invention discloses a supporting bracket with a fixing function for road and bridge building construction, and relates to the technical field of construction frames. Problems that according to anexisting supporting bracket, a clamping and fixing structure and a pushing and lifting structure need to be matched with a driving source (namely a motor) respectively, and the number of required motors is large are solved. The supporting bracket with the fixing function for road and bridge building construction comprises a protective guard. A mounting bottom plate comprises fixing shaft sleeves and lead screws, the mounting bottom plate is a long-strip-shaped structure, the two fixing shaft sleeves are symmetrically and vertically welded to the left side and the right side of the top end of the mounting bottom plate in a supported mode, the two lead screws are connected into the two fixing shaft sleeves in a screwed mode, and a supporting frame is installed at the top ends of the two leadscrews in an inserted mode; the whole supporting frame is a rectangular structure with the left end and the right end protruding outwards. The tail ends of four L-shaped pressing rods are inserted into the protective guard in an abutting mode so that treading operation of two feet is facilitated, and butt joint meshing of the two driving gears, a second gear and a first gear is convenient and efficient.

Description

technical field [0001] The invention relates to the technical field of construction frames, in particular to a support bracket with a fixing function for road and bridge construction. Background technique [0002] Bridges generally refer to buildings that are erected on rivers, valleys, etc. for passage, and are generally composed of five major parts and five small parts. To ensure safety, bridges are generally composed of superstructure, substructure and subsidiary structures. The superstructure mainly refers to the bridge span structure and support system; Shaped slope protection, bank revetment, diversion works, etc. During bridge construction, it is necessary to use bridge construction support devices for support to improve safety. [0003] For example, the patent No. CN201920957393.3 discloses a support bracket for bridge construction with a clamping function, including a support box and a base. The top of the support box is provided with a through hole, and the top o...

Problems solved by technology

[0005] The purpose of the present invention is to provide a support bracket with a fixed function for road and bridge construction, so as to solve the problems in the above-mentioned background technology that the clamping and fixing structure and the jacking and lifting structure need to be respectively equipped with a driving source (that is, a motor). Tight work and lifting work cannot share one power motor, and the demand for a large number of motors is a problem
