Problems solved by technology

[0005] 3. The hoisting construction time is long, the railway key points plan is cumbersome, and safety accidents are prone to occur;
[0006] 4. The range of protective scaffolding is large, which increases the construction risk;
[0007] 5. After the construction is completed, the protective scaffolding needs to be dismantled above the existing railway line, and there are still hidden dangers of accidents

Embodiment Construction

[0033] see figure 1 , figure 2 , the combined protective scaffolding in this embodiment includes:

[0034] A load-bearing structure positioned at the top of the bridge is set, the load-bearing longitudinal beam 12 in the load-bearing structure is based on the top surface of the bridge 15, and the load-bearing beam 9 spanning above the bridge is supported by the load-bearing longitudinal beam 12;

[0035] Set the steel structure frame at the bottom of the bridge, the frame longitudinal beam 1 in the steel structure frame is suspended below the load-bearing beam 9 by the suspender 8 and is located on both sides of the bridge; the frame beam 2 in the steel structure frame is suspended on the frame the bottom of stringer 1;

[0036] Set up a protective structure fixed on the steel structure frame, including anti-slag panels such as protective nets;

[0037] In order to realize the overall movement of the combined structure, a steel box 13 with foot rollers is arranged at the b...

Abstract

The invention discloses a combined type protection shed frame and a construction method thereof. The combined type protection shed frame is characterized in that a bearing structure located on the top surface of a bridge is arranged; the top surface of the bridge is taken as a bearing foundation by bearing longitudinal girders in the bearing structure; bearing cross girders crossing over the bridge are supported by the bearing longitudinal girders; a steel-structure frame located at the bottom part of the bridge is arranged; frame longitudinal girders in the steel-structure frame are suspended below the bearing cross girders through suspenders, and are located at both sides of the bridge; and frame cross girders in the steel-structure frame are suspended at the bottom parts of the frame longitudinal girders. The combined structure of the combined type protection shed frame disclosed by the invention is entirely borne on a bridge deck, and foundations do not need to be constructed at both sides of the existing railroad line, thereby, the on-site construction quantity of the existing railroad line is greatly reduced, the construction risk is lowered, the potential safety hazards areeliminated, and the interference on the normal operation of the existing railroad line is effectively reduced.

Description

technical field [0001] The invention relates to a protective scaffold for engineering construction and a construction method thereof, in particular to a protective scaffold and a construction method for protecting the safe operation of an existing railway line when a bridge above an existing railway line is demolished for construction. Background technique [0002] When demolishing the bridge above the existing railway line, it is necessary to protect the safe operation of the existing railway line. The current protective scaffolding for existing lines is a gate-shaped structure, that is, the gate-shaped structure foundation is constructed at the edge of the railway slope or road shoulder, steel pipe columns are hoisted, horizontal distribution beams and longitudinal beams across the railway are erected, and steel plates or bamboo springboards are finally installed. Anti-debris panels such as protective nets. There are some problems in the actual construction of this protec...
