Problems solved by technology

[0003]However, most of the existing trestles are designed with fixed structures, which can guarantee their overall stability, while the retractable movable trestles have There are certain defects, and there will be a difference in height between the plank road at the extension and the original plank road; therefore, it does not meet the existing needs, so we propose a steel structure trestle bridge with an extended frame and its implementation method

Embodiment approach

[0036] A method for implementing a steel structure trestle bridge with an extended frame, comprising the steps of:

[0037] Step 1: Nail trestle pillars 1 into the construction area according to the specified spacing. After the trestle pillars 1 are fixed and horizontally corrected, the central cross bridge 4 is hoisted above the middle pillars and anchored, and then the traditional The supporting cross bridge 3 is hoisted above other pillars;

[0038] Step 2: Control the lifting strut 24 in the middle section of the central cross bridge 4 to rise, then suspend the central lifting plank 10 above the lifting strut 24, and place the central lifting strut 10 horizontally on the top of the lifting strut 24, and fix After that, the lifting pole 24 is lowered and reset, and now the central lifting plank road 10 will descend together with the lifting pole 24, and keep the same horizontal height as the central cross bridge 4;

[0039] Step 3: Fix the four sets of extended misaligned ...

Abstract

The invention discloses a steel structure trestle with an extension frame and an implementation method of the steel structure trestle, and belongs to the technical field of trestles. In order to solve the problems that existing trestles are mostly of a fixed structural design, so that the overall stability of the existing trestles can be guaranteed, a telescopic movable trestle has a certain defect in stability, and a height difference exists between a trestle road at an extension position and an original trestle road, an extension staggered shaft steel frame is mainly composed of an upper part and a lower part; wherein a bearing hydraulic rod piece is arranged on one side of the movable steel sleeve, the bearing hydraulic rod piece is connected with the bridge floor trestle road above the bearing hydraulic rod piece and can control the lifting operation of the bridge floor trestle road, and the fixing sliding seat below the bearing hydraulic rod piece is connected with a transverse bridge used for supporting the whole trestle road structure. Bidirectional telescopic moving operation is achieved between the movable steel sleeve and the retention sliding seat through a driving wheel structure, and therefore lifting and moving operation of the bridge deck plank road is achieved.

Description

technical field [0001] The invention relates to the technical field of trestle bridges, in particular to a steel structure trestle bridge with an extended frame and an implementation method thereof. Background technique [0002] Buildings shaped like bridges, stations, ports, mines or factories, used for loading and unloading goods or getting on and off passengers, or temporary bridge structures specially used for construction site traffic, mechanical layout and overhead operations, in civil engineering, for transporting materials, Temporary bridge facilities built for equipment and personnel are divided into wooden trestles and steel trestles according to the materials used. The trestle in the railway ferry is a bridge structure for locomotives to drive on and off the ferry. The trestle consists of piers, abutments, Composed of steel girders, springboard girders and lifting machinery and equipment, the structure of the trestle bridge is basically the same as that of the bri...
