Problems solved by technology

But in this way, it has brought great problems to the construction: (1) The construction period of the building has been extended
This further prolongs the construction period
(3) Since the floor slab has been poured at this time, workers are forced to construct without a tower crane, and it is very inconvenient to shift heavy components

Embodiment Construction

[0016] The present invention proposes the structure of connecting nodes through beams and supports, so that the embedded small frame support allows vertical displacement of the steel beam, so that the vertical load will not be transmitted to the support, and the embedded small frame support does not participate in bearing the vertical load; The support and the steel beam are in close contact in the horizontal direction, and there is no horizontal relative slippage. When the steel frame moves sideways under the action of a horizontal earthquake, the support point also moves horizontally at the same time. The support participates in bearing the horizontal force and plays an anti-seismic role. .

[0017] The purpose and effects of the present invention will become more apparent by describing the present invention in detail below with reference to the accompanying drawings.

[0018] As shown in the figure, the gravity-free embedded small frame seismic structure of the present inve...

Abstract

The invention discloses an embedded small frame earthquake resistant structure of bearing force-free, which is composed by overlaying a plurality of embedded small frame supporting units. The embeddedsmall frame supporting unit includes a steel column, a steel beam, an inner frame upright column, an inner frame beam, a supporting corbel, a steel beam corbel, a screw bolt, a steel shim, beam-column joints and supporting joints. The steel beam and the steel column is connected via beam-column joints, two inner frame upright columns are connected with the steel beam via supporting joints, the upper flange of the inner frame beam is provided with a supporting corbel that connceting with lateral side of a steel beam welded on lower flange of the steel beam via screw bolts, screw bolt holes onthe supporting corbel and the steel beam corbel are elliptical holes with vertical axis, steel thin gasket is provided between the supporting corbel and the steel beam corbel. The invention provided embedded small frame of one hundred percentage bearing capacity and rigidity is used for resisting horizontal earthquake action without affecting construction progress, using local materials. The invention provided is a excellent earthquake resistant energy consuming component with advantages of good earthquake resistance, high ductility and full energy hysteresis loop.

Description

technical field [0001] The invention relates to the technical field of building structure engineering, in particular to a bearing-free and anti-seismic steel support structure. Background technique [0002] Embedded small frame support is one of the effective steel structure components to enhance the lateral stiffness and lateral bearing capacity of single-story, multi-layer and high-rise steel structures. The small frame support is arranged in the steel frame structure, so that the lateral force resistance of the entire structure It has been greatly improved, so that the steel structure is suitable for the construction of taller buildings. [0003] The purpose of setting up the embedded small frame support is to improve the lateral stiffness of the structure and the strength of the structure against lateral force. However, due to the rigid connection between the two ends of the embedded small frame support and the beam column, when the column undergoes compression deformat...
