Abstract
The utility model relates to a semi -rigid node of combination steel sheet connection type mainly includes rectangle steel core concrete column, girder steel, combination steel sheet connecting piece and wears muscle formula high strength bolt. The girder steel is connected through combination steel sheet connecting piece and rectangle steel core concrete column indirectness, wherein makes up the steel sheet connecting piece and connects on the rectangle steel core concrete column through wearing muscle formula high strength bolt, and it can an effectual transmission roof beam transverse force to wear muscle formula high strength bolt. Size through adjustment combination steel sheet connecting piece and the quantity of wearing muscle formula high strength bolt change the semi -rigid of node, and then the turning power of adjusting the node, and the designing requirement of better realization ductility node is a simple structure, and it is clear and definite to pass power, construction convenience's novel semi -rigid joint form.
Description
Technical field
The invention belongs to technical field of structural engineering, relate to a kind of combined steel plate connecting-type structures with semi-rigid joints form.
Background technology
Steel concrete combinative structure is the fifth-largest class formation developing rise after timber structure, masonry structure, reinforced concrete structure and steel construction, and its subject originates from the twentieth century initial stage, has arrived the fifties and has basically formed independent subject system.In recent years, owing to concrete-filled rectangular steel tube has, joint form is simple, cross sectional moment of inertia is big, stability is good, be easy to particular advantages such as taking precautions against fire, and its range of application is more and more extensive.Joints for CFST Frame is generally designed to hinged joint or rigid joint by people, is susceptible to brittle break due to problems such as node bending rigidity are weak, ductility is poor, welding residual stress is big under geological process.
At present in the research of China, it is board-like that through ribbed connection joint form is mainly the through overhanging end of bolt, and i.e. girder steel is by angle steel, welded end plate or T-steel, is connected with post with the long high-strength bolt of through shaft, after the concrete in pipe reaches some strength, to shank of bolt Shi Hanzhang.This node has preferable ductility and bending rigidity, and node does not has welding residual stress, is the Semi-rigid Joints form of a kind of good seismic performance.
Great many of experiments data shows, varied rigid link concrete-filled steel tubular frame is preferable deformability and energy dissipation capacity because node has, can the natural vibration period of extending structure, can dissipate seismic energy by controlling beam-ends plastic hinge, prevent from causing collapsing of structure because connecting destruction of a node, thus it is substantially reduced earthquake, beneficially antidetonation.Therefore research structures with semi-rigid joints new model, it is achieved the popularization and application in Practical Project of the Aseismic Design of ductility joint, significant.
Utility model content
Invention of the present utility model is to promote steel performance application in engineering construction, it is provided that a kind of novel structures with semi-rigid joints form being conducive to structural seismic, prevents from causing the collapse of structure because connecting destruction of a node.
In order to realize above-mentioned node new model, the technical scheme is that steel beam flange and web and rectangular steel-tube concrete column are connected by combined steel plate connector, wherein combined steel plate connector is connected by through ribbed high-strength bolt with rectangular steel-tube concrete column, and welds with lower flange on girder steel and web.
This utility model has the advantage that.
1, through ribbed high-strength bolt instead of the effect of internal partition, can effectively transmit pulling force and the pressure of lower flange on girder steel.Compare external partition joint form, there is the advantages such as power transmission direct, saving steel, guarantee space.
2, through ribbed high-strength bolt takes up space less compared to internal partition, is more beneficial for the perfusion tamping of pipe inner concrete.
3, power transmission clearly, simple structure, easy construction, by changing gauge size and the quantity of through ribbed high-strength bolt of combined steel plate connector, can preferably realize the design concept of ductility joint with the size of adjustment node rigidity.

Detailed description of the invention
Referring to accompanying drawing, the utility model is described in further detail.
Combined steel plate connecting-type structures with semi-rigid joints, including rectangular steel-tube concrete column (1), girder steel (2), combined steel plate connector (3), through ribbed high-strength bolt (4) and weld seam (5).Combined steel plate connector (3) uses full penetration groove weld (5) to be pre-welded on girder steel (2) in factory, is connected with rectangular steel-tube concrete column (1) by through ribbed high-strength bolt (4) at building-site, has simple structure, the feature of easy construction.
The steel core concrete column (1) that this utility model relates to is square section form.Described girder steel (2) is steel I-beam.Described concrete is normal concrete, high-strength concrete or self-compacting concrete.
The relevant technology contents do not addressed in aforesaid way is taked or uses for reference prior art to realize.
Claims (3)
1. combined steel plate connecting-type structures with semi-rigid joints, it is characterised in that be made up of rectangular steel-tube concrete column, girder steel and Force transmission parts;
Described Force transmission parts includes combined steel plate connector, through ribbed high-strength bolt and weld seam;Combined steel plate connector is welded with girder steel by weld seam, is connected with rectangular steel-tube concrete column by through ribbed high-strength bolt, and wherein through ribbed high-strength bolt to ensure having enough prestressing force, and bolt head uses double nut simultaneously.
Combined steel plate connecting-type structures with semi-rigid joints the most according to claim 1, it is characterized in that: combined steel plate connector is connected by through ribbed high-strength bolt with rectangular steel-tube concrete column, full penetration groove weld is used to weld with lower flange on girder steel and web, its effect is pulling force and the pressure of lower flange on girder steel to be effectively delivered on through ribbed high-strength bolt, allows through ribbed high-strength bolt play the effect of internal partition.
Combined steel plate connecting-type structures with semi-rigid joints the most according to claim 1, it is characterized in that: by adjusting size and the quantity of through ribbed high-strength bolt of combined steel plate connector, control the turning power of node, and then improve ductility of joint and energy dissipation capacity, it is a kind of novel structures with semi-rigid joints form.
