Abstract
The utility model relates to a buckling restrained continuous bending web member truss, comprising an upper chord and a lower chord, wherein thin-wall steel tubes with equal sections are obliquely and symmetrically arranged between the upper and lower chords in a continuous bending way; and web members at the ends of the thin-wall steel tubes are provided with outer sleeves. The buckling restrained continuous bending web member truss has strong bearing capacity, less needed materials, and low construction cost, and is simple to operate and convenient to dismount.
Description
Technical field
The utility model belongs to the architectural shape technical field, is specifically related to a kind of buckling-restrained continuous bending web member.
Background technology
Trussed construction is usually used in the public buildings such as factory building, exhibition hall, sports palace and bridge of large span.The truss here refers to girder truss, is a kind of girder structure of latticeization.Its primary structure characteristics are that each rod member is stressed all to be drawn, press based on unidirectional, and by the reasonable Arrangement to last lower chord and web member, but the moment of flexure of commensurate structure inside and shearing distribute.Because the internal force that draws, presses of horizontal direction has been realized self balance, total does not produce horizontal thrust to bearing.Structural configuration is flexible, and range of application is very wide.Girder truss and solid web girder (be us general being seen beam) are compared, aspect bending resistance since with the cross section centralized arrangement of tension and pressurized at two ends up and down, increased the interior arm of force, feasible with same material usage, realized bigger flexural strength.Aspect shearing resistance,, shearing progressively can be passed to bearing by the reasonable Arrangement web member.So no matter to be bending resistance or shearing resistance, trussed construction can both make the strength of materials be not fully exerted, thereby is applicable to the building roof structure of various spans.Prior meaning is that also it is converted into simple tension and compression stress state in the truss member with the inner complicated stress state of the solid web girder under the horizontal curved effect, makes us can understand the distribution and the transmission of power intuitively, is convenient to the variation and the combination of structure.In the member of truss, the end web member is a rod member of stressed maximum in the web member, because the compression bearing of the pipe of web member is less than the tension bearing capacity, so in order to address this problem, generally be to become other section forms to improve its bearing capacity end web member additional designs.
Academia has proposed a kind of notion of buckling-restrained support recent years both at home and abroad, and buckling-restrained support claims not have bonding again to be supported, and is that a kind of new steel structure supports, and also is that a kind of power consumption is supported.The center of buckling-restrained support is a core, makes with the low-yield steel, allows bigger plastic strain under responsive to axial force, can reach the purpose of power consumption by this distortion.Complete buckling when avoiding the core pressurized promptly can both reach surrender when tension and pressurized, core is placed in the steel sleeve, then concrete perfusion or mortar in sleeve pipe.For reducing or eliminate and pass to mortar or concrete power when core is subjected to spool power, and because poisson effect, core can expand under the pressurized situation, therefore is provided with one deck non-cohesive material or very narrow and small air layer between core and mortar.So, also can reach surrender fully when this is supported on pressurized, make the support compression bearing suitable with the tension bearing capacity, overcome the shortcoming of traditional support pressurized flexing, improve the supporting capacity that supports, made the hysteresis loop of support full, improved the shock resistance of structure.When the design that constraint is supported, needn't consider unstability, only calculate its intensity, think that support tension and pressurized performance are identical, when pressurized flexing can not take place.
Summary of the invention
For made full use of material intensity, improved the supporting capacity of member, the utility model is applied to truss with buckling-restrained support concept, has reduced workload significantly, makes production efficiency significantly improve.The purpose of this utility model provides a kind of supporting capacity that improves member, and simple to operate, convenient disassembly, materials are economized a kind of buckling-restrained continuous bending web member that construction cost is low.
The technical scheme of architecture advances is as follows:
A kind of buckling-restrained continuous bending web member comprises pricncipal rafter, truss lower chord, the thin-wall steel tube of oblique symmetric arrangement equal section between pricncipal rafter and the truss lower chord, and described thin-wall steel tube adopts the mode of continuous bending; The end web member of thin-wall steel tube is provided with outer sleeve.
Described pricncipal rafter, truss lower chord are the light gauge cold-formed steel shape of steel pipe, angle steel, channel-section steel or " W " type;
The web member of described pricncipal rafter, truss lower chord all adopts fillet weld to be connected with chord member;
The beneficial effects of the utility model are embodied in:
1, buckling-restrained support concept is applied to the local web member of truss, continuous web member section is reduced generally, thereby improve the utilization rate of material.
2, proposed the form of the continuous bending of truss web, reduced artificial consumption significantly, practicable standardization, mechanization production make production efficiency significantly improve.
3, when adopting hot-finished material, the web member of truss purlin all adopts fillet weld to be connected with chord member, and such connected mode had both guaranteed the intensity of panel point, made that also the outward appearance of truss is clean and tidy.
4, when adopting zinc-plating material, web member adopts galvanized bolt to be connected with chord member, guarantees corrosion resistant performance, avoids containing the Zinc material welding and produces toxic gas.
