Abstract

The invention provides a cantilevered scaffold body for beam slab overhanging structures. The cantilevered scaffold body, which is arranged at a position where beam slabs overhang, comprises cantilevered girders, anchoring girders, U-shaped anchor bolts and wire ropes, the anchoring girders are put on the beam slabs of both sides at the structure overhanging position, the cantilevered girders are put on the anchoring girders and anchored by the U-shaped anchor bolts, the ends of the cantilevered sections of the cantilevered girders are connected with the wire ropes, and the wire ropes are tied with hanging rings. The cantilevered scaffold body for beam slab overhanging structures has the advantage that because the anchoring girders are arranged at the position of the overhanging structure and anchored with the cantilevered girders, the construction problem that the cantilevered scaffold body cannot be built for the overhanging structure does not have the anchoring condition is solved. Conventional cantilevered steel which is 5m to 6m in length can be used as the cantilevered girder to meet the construction and safety requirements of the cantilevered scaffold body, construction is simple, and steel usage is only 40 percent of the steel usage of the conventional method; because the cantilevered girders are anchored with the anchoring girders, the construction load on the cantilevered scaffold body is transferred to a main structure, so the safety factor is high.

Description

The beam slab aerial construction support body of encorbelmenting
Technical field
The present invention relates to a kind of building operations structure, particularly a kind of beam slab aerial construction support body of encorbelmenting.
Background technology
Builder's jack is to utilize the primary structure member of overhanging type steel beam as support body outside top, taking single overhanging type steel beam as unit and agent structure floor fix, the whole load of outer support body passes on overhanging type steel beam, mainly rely on the anchoring of Cantilever Beams and structure floor reach with outer support body on the balance of load.As shown in Figure 1,2,3, 4, the support body of encorbelmenting reaches and the balance of outer support body load by the anchoring of Cantilever Beams end and structure beam slab, its implementation process is embedded U-shaped crab-bolt 3 on structure beam slab 2, overhanging type steel beam 1 is evenly arranged on structure beam slab through U-shaped crab-bolt 3 is parallel, and U-shaped crab-bolt 3 tops arrange shaped steel, bolt tightening standby tight with timber wedge.
Due to the complexity of building structure, usually there is beam slab aerial construction in agent structure, and this place's overhanging type steel beam 1 is without anchoring condition, and the support body of encorbelmenting cannot be set up.Adopt conventional method, what aerial construction position counted overhanging type steel beam 1 encorbelments segment length as shown in Figure 4, for ensureing that the frame body safe of encorbelmenting must increase overhanging type steel beam 1 length, sectional dimension, overhanging type steel beam 1 length and sectional dimension reach 2-3 times of conventional overhanging type steel, shaped steel consumption increases, and the end of encorbelmenting must increase wire rope 5 and carry out off-load ability balance external support body load, and difficulty of construction is very big, safety factor is low, in reality construction, cannot realize.
Summary of the invention
For structural problem in prior art, the object of this invention is to provide a kind of beam slab aerial construction support body of encorbelmenting, the construction difficult problem that cannot set up without anchoring condition, the support body of encorbelmenting to solve structural frame vacancy overhanging type steel beam.
For achieving the above object, the technical solution used in the present invention is to provide a kind of this support body of encorbelmenting and is arranged on the built on stilts place of beam slab, include overhanging type steel beam, wherein: this support body of encorbelmenting also includes anchoring girder steel, U-shaped crab-bolt, wire rope, in the structural beams of both sides, the built on stilts place of described beam slab, set up anchoring girder steel, on anchoring girder steel, be erected with overhanging type steel beam, and by U-shaped crab-bolt anchoring, the section of the encorbelmenting end of overhanging type steel beam is connected with wire rope, wire rope and suspension ring drawknot.
Effect of the present invention is, at aerial construction place, anchoring girder steel is set, and by anchoring between overhanging type steel beam and anchoring girder steel, solves the construction difficult problem that aerial construction place cannot set up without anchoring condition, the support body of encorbelmenting.In structure of the present invention, overhanging type steel beam uses shaped steel that conventional length dimension is 5-6m can meet construction and the safety requirements of the support body of encorbelmenting, and construction is simple, and steel use amount is only 40% of conventional method; Utilize structure on two sides beam slab to set up anchoring girder steel, by overhanging type steel beam and the anchoring of anchoring girder steel, the working load of encorbelmenting on support body is passed to agent structure, stressed clear and definite, safety factor is high.

Detailed description of the invention
By reference to the accompanying drawings beam slab aerial construction suspension scaffold body structure of the present invention is illustrated.
The beam slab aerial construction of the present invention support body of encorbelmenting, this support body of encorbelmenting is arranged on the built on stilts place of beam slab, include overhanging type steel beam, this support body of encorbelmenting also includes anchoring girder steel 4, U-shaped crab-bolt 3, wire rope 5, in the structural beams of both sides, the built on stilts place of described beam slab, set up anchoring girder steel 4, on anchoring girder steel 4, be erected with overhanging type steel beam 1, and by U-shaped crab-bolt 3 anchorings, the section of the encorbelmenting end of overhanging type steel beam 1 is connected with wire rope 5, wire rope 5 and suspension ring 6 drawknots.
The beam slab aerial construction of the present invention support body of encorbelmenting arranges anchoring girder steel 4 at built on stilts beam slab place, overhanging type steel beam 1 passes through U-bolt 3 anchorings with anchoring girder steel 4, meet the anchoring requirement of overhanging type steel beam 1, the difficult problem that support body cannot be set up thereby encorbelment in the built on stilts beam slab of solution place.This structure stress is clear and definite, easy construction, safety factor are high.
