Abstract

The invention relates to a dismantling method for resisting an impact load in the high-altitude overhanging steel-structure-platform dismantling process. The dismantling method is characterized by including the following steps that 1, the cutting position of a steel truss is determined, a slotting line is drawn up, the steel truss is divided into two parts, one part is a fixing-section steel truss body connected with a concrete body structure, and the other part is a lifting-section steel truss body far away from the concrete body structure; 2, an outer-side lifting point of the lifting-section steel truss body and a structural tower lifting hook are fixed, a lifting rope is frapped, an inner-side lifting point of the lifting-section steel truss body is fixed through an inner-side lifting-device lifting hook, and the lifting rope is frapped; 3, an auxiliary hanging plate stretches across the slotting line, is fixed at the upper portion of the steel truss and fixedly connected with the lifting-section steel truss body, and is not connected with the fixing-section steel truss body; 4, the steel truss is cut off in the slotting line, then the lifting-section steel truss body is lifted through the inner-side lifting point and the outer-side lifting point of the lifting-section steel truss body, and the lifting-section steel truss body is dismantled. According to the dismantling method, the construction cost is low, and the impact load in the dismantling process can be resisted.

Description

The method for dismounting of impact load during opposing high-altitude overhanging steel structure platform removal
Technical field
The present invention relates to a kind of resist the method for dismounting of impact load during high-altitude overhanging steel structure platform removal, belong to Hoisting and hanging technical field.
Background technology
In urban construction, for meeting elevation of building effect requirements, high-rise, Super High long cantilever construction application gets more and more. High Large Cantilever structure construction typically uses Steel Cantilever Truss structure as stay in place form rack platform, uses traditional handling to tear open Except mode, select the lifting rope of large-scale hoisting machinery and major diameter to increase stress, prevent from disconnecting wink at steel truss with steel truss Between produce impact load lifting rope is had a negative impact.Impact load for opposing moment selects large-scale hoisting machinery with big The lifting rope of diameter, not only increases and removes cost, and waste resource.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of opposing high-altitude overhanging steel structure platform The method for dismounting of impact load in demolishing process, construction cost is low and can resist the impact load in demolishing process.
The technical scheme provided according to the present invention, impact load during a kind of opposing high-altitude overhanging steel structure platform removal Method for dismounting, feature is, comprises the following steps:
(1) determining the cutting position of steel truss, draw slot line, steel truss is divided into two parts, one is and concrete agent structure The canned paragraph steel truss connected, another part is remote from the handling section steel truss of concrete agent structure;
(2) the outside suspension centre of handling section steel truss is fixed with structure crane hook, tightens up lifting rope;The inner side of handling section steel truss Inside suspension centre employing, boom hoisting suspension hook is fixed, and tightens up lifting rope;
(3) fixing one piece of auxiliary link plate across slot line in steel truss top, auxiliary link plate is fixing with handling section steel truss to be connected, Auxiliary link plate is not connected to canned paragraph steel truss;
(4) cut off steel truss along slot line, then by the suspension centre inside and outside handling section steel truss, handling section steel truss sling, Handling section steel truss is removed.
Further, described inner side boom hoisting suspension hook is arranged at inside building structure.
Further, described auxiliary link plate is welded by soldered with handling section steel truss, auxiliary link plate and canned paragraph steel Truss is not connected to.
The method have the advantages that owing to this method utilizes the fixing steel construction do not removed to undertake impact load, Without selecting the lifting rope of large-scale crane gear and major diameter, cost savings effect during high-altitude overhanging steel structure platform removal Benefit is substantially.

Label in figure: structure crane hook 1, handling section steel truss 2, auxiliary link plate 3, soldered 4, slot line 5, concrete master Body structure 6, canned paragraph steel truss 7, inner side boom hoisting suspension hook 8.
Detailed description of the invention
Below in conjunction with concrete accompanying drawing, the invention will be further described.
The method for dismounting of impact load during opposing high-altitude overhanging steel structure platform removal of the present invention, including following Step:
(1) as it is shown in figure 1, determine the cutting position of steel truss, draw slot line 5, steel truss be divided into two parts, one be with The canned paragraph steel truss 7 that concrete agent structure 6 connects, another part is remote from the handling section steel truss 2 of concrete agent structure 6;
(2) as shown in Figure 2 to 4, the outside suspension centre of handling section steel truss 2 utilizes existing structure crane hook 1 to fix, and tightens up Lifting rope;The inner side suspension centre of handling section steel truss 2 uses the internal inner side boom hoisting suspension hook 8 arranged of building structure to fix, and tightens up Lifting rope, when preventing from cutting off truss, the outside sliding of handling section steel truss;
(3) link plate 3, auxiliary link plate 3 is assisted to weld with handling section steel truss 2 across slot line 5 in steel truss upper weld one piece, Auxiliary link plate 3 is not connected to canned paragraph steel truss 7;As in figure 2 it is shown, by soldered between auxiliary link plate 3 and handling section steel truss 2 4 connect;
(4) cutting off steel truss along slot line 5, cutting off moment, auxiliary link plate 3 can play the work of opposing steel truss tenesmus impact With, impact load is passed to canned paragraph steel truss 7 by auxiliary link plate 3;Again by hanging inside and outside handling section steel truss 2 Handling section steel truss 2 is hung ground by point, it is achieved the purpose removed by handling section steel truss 2.
