Description
Technical field
The utility model relates to a kind of building connecting elements, particularly relates to a kind of herringbone box section that is suitable for and supports the building connecting elements with i-shaped roof beam.
Background technology
Radius of gyration in I-steel member section plane is much larger than out-of-plane radius of gyration, and the inside and outside radius of gyration of box-shaped steel beam column plane is more or less the same, when cross sectional area is identical, box-shaped steel beam column bears large many of the ability of axial compression or press-bending than I-steel component, therefore, under identical supporting capacity, cross section and the I-shaped cross-section of box-shaped steel beam column are little.
Steel work is because its intensity is high, from heavy and light, anti-seismic performance is good, and it is high that industrialization makes degree, the features such as job site is easy for installation, speed of application is fast, is now developed business gradually and accepts, especially high intensity Zone, and steel construction, structure are more and more.Unbraced frames steel work rigidity is relatively weak, the height being suitable for building is relatively low, and steel frame---Bracing Systems maxi-mum height much larger than pure steel frame structure, the section form of support and support connected mode also one of the important feature becoming structure design with framework.
Vierendeel girder mainly bears the bending and shearing that load of floor and horizontal loading transmit, and adopts i section steel beam namely to meet requirement for bearing capacity, again constructability, cost-saving; But support assume responsibility for huge axial compression, if employing I-shaped cross-section, because I-shaped cross-section exists strong and weak axle, the cross section of so I-shaped support can be very large or steel plate thickness is thicker, uneconomical and the problem of a series of structure or the construction technology aspect produced because cross section is large or steel plate is thick can be caused, adopt box section if support, then relatively little cross section or thinner steel plate thickness can be used just can to meet the requirement of bearing capacity.Therefore the structural form selecting i section steel beam and box section to support, get final product saving steel, reduce costs, again can constructability.
Summary of the invention
The purpose of this utility model is to provide a kind of herringbone box section that is suitable for support the building connecting elements with i-shaped roof beam, the utility model makes full use of the cross section property of component, adopt box-shaped support and i section steel beam, only in the certain limit of junction, the both sides of I-shaped cross-section are increased twice floor, support and be welded to connect with girder steel, constructability, saves steel, saves construction costs.
The purpose of this utility model is achieved through the following technical solutions:
A kind of herringbone box section that is suitable for supports the building connecting elements with i-shaped roof beam, described component comprises i section steel beam, the outermost end of twice floor is increased after on connected node place i section steel beam, the connected node floor of herringbone node both sides, middle floor, herringbone Nodes corresponds to the bearing length of box-shaped support, floor is increased after on i section steel beam, box-shaped support, the position while welding that box-shaped support and node directly weld, herringbone box section supports the connection with i section steel beam, girder steel, herringbone box section supports and is connected with i section steel beam herringbone, support and directly weld with herringbone node, the distance of connected node floor and rear increasing floor is the girder steel height of 0.5 times, and the bearing length of connected node floor, middle floor, rear increasing floor welds with i section steel beam.
Described a kind of herringbone box section that is suitable for supports the building connecting elements with i-shaped roof beam, and the position while welding that box-shaped support described in it and node directly weld is welded to connect.
Advantage of the present utility model and effect are:
1. make full use of the cross section property of component, adopt box-shaped bracing members, reduce the sectional dimension supported.
2. only in junction, the both sides of i section steel beam are increased twice floor.
3. adopt comparatively primary structural component sectional dimension, simple structure, save material, reduce construction cost.
