Description

Beam-end sliding support of H shaped steel structure roof beam with zip of preventing falling

Technical Field

The utility model relates to a building steel construction field specifically is a beam-ends sliding support of H shaped steel structure roof beam with zip of preventing falling.

Background

With the development of the building industry and the change of building requirements, for the reasons of convenient traffic, beautiful building shapes and the like, corridor-type structures connecting a plurality of main buildings are increasingly applied to various public buildings and commercial buildings; these galleries connect multiple buildings to form a multi-tower connected structure system. The corridor is generally large in span and therefore often takes the form of a steel structure. Because the rigidity, the mass and the dynamic characteristics of the connected main buildings are different, under the action of horizontal load (such as earthquake action or wind load action), the vestibule structure needs to be capable of coordinating the displacement deformation between the connected main buildings; therefore, the support node of the corridor structure connected with the main building is a part needing important research and analysis in the design stage.

Some connected structures are under consideration for processing the connecting nodes of the corridor and the main building, or the actually designed connecting node structure mode cannot meet the stress and deformation conditions of theoretical analysis, for example, stress and deformation analysis are considered according to sliding of the steel structure beam at the end part of the corridor and the main building during theoretical calculation, but the actual support node structure design cannot realize the sliding effect; or because of insufficient safety measures for falling prevention and the like, the conjoined structure has a possibility of generating safety problems, and the conjoined structure cracks if the conjoined structure is light and even falls if the conjoined structure is heavy.

Disclosure of Invention

The utility model provides a beam-ends sliding support of H shaped steel structure roof beam with zip of preventing falling, the utility model discloses the support can require release beam-ends internal force and corresponding displacement according to building structure's atress, realizes the gliding effect of beam-ends, prevents that the beam-ends structure from receiving the damage to it calculates gliding design hypothesis to satisfy the theory.

The utility model provides a following technical scheme:

the utility model provides a beam-ends sliding support of H shaped steel structure roof beam with zip of preventing falling, the support end of vestibule structure roof beam is enlarged end structure to on laying aside the pre-buried horizontal steel sheet of main building, the terminal surface forms the confined cavity all around by two rectangle steel pipes of welding around and two shrouding of welding about and under the enlarged end, welds the spacing key on the horizontal steel sheet, and the spacing key is withheld to the confined cavity all around, and the spacing key is located the confined cavity.

The enlarged end can generate relative sliding displacement relative to the horizontal steel plate, and the relative displacement deformation between main buildings can be adjusted and released through the sliding of the corridor sliding support; the limit value of the sliding of the support is controlled by the cavity and the limit key which are sealed at the periphery while the support slides, so that the structure is prevented from falling due to overlarge displacement of the support.

And a limiting baffle is welded on the outer side of the enlarged end on the horizontal steel plate. The limit baffle can prevent that when spacing key desoldering or cavity warp, when the support displacement lost control, limit baffle still can prevent the beam-ends further crooked, prevents that the structure from falling.

The main building is characterized in that a vertical steel plate is embedded in the vertical face of the front end of the main building, one end of a steel strand zipper is connected to the vertical steel plate, a through hole is formed in a front-end rectangular steel pipe, the other end of the steel strand zipper penetrates through the through hole to reach the inside of the closed cavity, and a buckle is arranged at the end of the steel strand zipper.

The steel strand inhaul cable can prevent that when the limiting key is off-welded or the cavity is deformed and the displacement of the support is out of control, the steel strand lock catch can still draw the structural beam end to prevent the structure from falling; and providing a second insurance.

The side part of the enlarged end is provided with a bolt connecting plate, the matching position on the horizontal steel plate is provided with a bolt, and the bolt connecting plate and the horizontal steel plate are anchored by the bolt. Bolt holes in the bolt connecting plates are waist holes, the bolts are mainly used for fixing the positions of the beam ends during construction, after the structural beam is put into use, the waist hole bolt holes can provide room for small displacement of the bolts, and when severe displacement sliding such as earthquake occurs, the bolts are completely pulled loose and released, so that large-amplitude sliding displacement is realized.

The corridor structure beam is H-shaped steel, the enlarged end is an H-shaped steel upper and lower flange plate widening structure, and a plurality of stiffening plates are arranged between the upper and lower flange plates. The stiffening plate improves the structural rigidity and strength of the beam end.

Compared with the prior art, the utility model discloses possess following beneficial effect:

1. the utility model discloses the support can require release beam-ends internal force and corresponding displacement according to building structure's atress, realizes the gliding effect of beam-ends, prevents that the beam-ends structure from receiving the damage to it calculates gliding design hypothesis to satisfy the theory.

2. The arrangement of the limiting keys and the limiting baffle plate enables the displacement of the beam end sliding support node of the steel structure beam to be controlled according to the design requirement of the structure, and the applicability of the sliding support is improved.

3. The steel strand anti-falling zipper for preventing the structure from falling due to overlarge support displacement is a second safety defense line of the sliding support, and the force transmission reliability of the sliding support is guaranteed from the structural structure, so that the safety performance of the whole conjoined structure is improved.
