Description
Technical field
The utility model relates to a kind of close column frames of multispan, in particular to the band support of a kind of excellent earthquake resistance is more than two layers
Across close column frame.
Background technique
Currently, country building is mostly low layer, quake-resistant safety degree is low, and the structural system for improving country building can effectively enhance it
Shock resistance.Steel-frame structure can be divided into pure frame structure, center support frame structure, eccentric branch by anti-lateral displacement hierarchical taxonomy
Frame structure etc. is supportted, the whole anti-side rigidity of pure frame structure is smaller, and it is rigid that setting support can effectively improve structure entirety anti-side
Degree.Supporting form is generally K-type, Y type, X-type, herringbone.In multilayer multiple bay frame structure, support generally a certain across interior,
Upper and lower level is continuously arranged, or constitutes bandy truss in a certain layer setting of high-rise frame building.However, these support arrangement shapes
Formula is obtained by the engineering experience and multiple tentative calculation of designer, and structure lateral resistance behavior still has room for improvement.Light steel knot
Structure, light-duty wooden structural system be mostly close column frame, cost is more cheap, be suitable for low layer farm building.Close column frame
Internal force based on moment of flexure, load-carrying efficiency is lower, and anti-seismic performance is poor, needs a kind of load-carrying efficiency of excellent earthquake resistance high
Close column frame solve the above problem.
Summary of the invention
Purpose of the utility model is to solve close column frame load-carrying efficiency is lower at present and anti-seismic performance is poor
The band support close column frame of two layers of multispan of problem and a kind of excellent earthquake resistance for providing.
The band support close column frame of two layers of multispan of excellent earthquake resistance provided by the utility model is in two layers of close column of multispan
It is provided with the X-type support through two layers in frame, the support of M type is provided in the close column frame of bottom multispan.
The central point of X-type support is located at the center of the close column frame of two layers of multispan, and two sides lower part of X-type support is the bottom of at
The angle of part and horizontal plane in the close column frame of multispan of layer is 45 °, multispan of the two sides top that X-type supports in the second layer
It is connected after intersecting at part and 1/8 height of the first root post close to side column in close column frame with the vertex of side column.
The central point on two vertex and X-type support that M type is supported in the close column frame of bottom multispan is located at a height,
Positioned at the top of the close column frame of bottom multispan.
The manufacturing process of the utility model:
The band support close column frame of two layers of multispan of excellent earthquake resistance provided by the utility model is in production, it is first determined
Center pillar midpoint A and bottom terminal B on symmetrical configuration axis set the horizontal of 45 ° of support in bottom, form the X-shaped of cross-layer
The middle section of the lower half portion of support and the support of M shape, i.e. connection AF, BE.In the first root post close to side column away from top
A point C is determined at highly 1/8 stem height, is connected AC and CD, is formed complete X-shaped；EJ is connected, complete M shape is formed.
When design seismic intensity is greater than seven degree, support and the connection of frame can be linked at one by welding or bolt
It rises, for the continuity for guaranteeing support, in the point of intersection of support and beam column, to hollow section component, the component port of disconnection is arranged
With the consistent ribbed stiffener of cross-sectional internal size, rib thickness of putting more energy into should be consistent with component thickness, and ribbed stiffener is using welded connecting；To branch
Node A, H, I are intersected in support with beam column, can be used and mutually pass through node, ribbed stiffener is preferably arranged inside node.To solid section, then to guarantee
The close and connection reliability of section contact.
The utility model has the beneficial effects that
The band support close column frame cross-layer of two layers of multispan of excellent earthquake resistance provided by the utility model is provided with continuous branch
Support, and the support of different interlayers or intercolumniation is connected in the form of straight line.Horizontal lateral force is directly delivered to basis, is supported as side
To the main Path of Force Transfer of power, structural bending moments internal force is effectively reduced, increases substantially structural seismic performance.Compared to the close column of tradition
Frame, the utility model intercolumniation become larger, and can save column material, and the column material of saving is used to support, and structural material dosage changes not
Greatly, and structural bearing efficiency is improved.Supporting form is simple and novel, is convenient for site operation, and it is raw that assembled plant can also be used
It produces.
