Description

A kind ofly be suitable for the lower end that box-shaped support is connected with i-shaped roof beam and build node
Technical field
The utility model relates to one, particularly relates to a kind ofly being suitable for the lower end that box-shaped support is connected with i-shaped roof beam and building node.
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 and is suitable for the lower end that box-shaped support is connected with i-shaped roof beam and builds node, the utility model adopts i section steel beam and box-shaped support, only in the certain limit of junction by position corresponding for box-shaped support two side, i section steel beam both sides, set up twice floor, the wasting of resources that the connection of the connection or box steel beam and box-shaped support that solve traditional i section steel beam and I-shaped support causes, complex structure, deficiency that cost is high.
The purpose of this utility model is achieved through the following technical solutions:
A kind ofly be suitable for the lower end that box-shaped support is connected with i-shaped roof beam and build node, described node comprises steel column, box-shaped support, i section steel beam, the outermost end of twice floor is increased after connected node place i section steel beam, the first floor that box-shaped support top and bottom sidewall is corresponding, the second floor that on steel column, girder steel is corresponding with post with support wall in order, the trislab increased after on the i section steel beam that Nodes is corresponding with box-shaped support sidewall, be supported on the corner cut of steel column and girder steel touching position, i section steel beam is connected with box-shaped support, i section steel beam both sides increase twice steel plate thickness with the identical floor of box-shaped support two side thickness, this floor to stretch out the girder steel depth of section of 0.5 times along supporting the outermost floor connected with girder steel, the sidewall supported welds mutually with steel beam surface.
Described be a kind ofly suitable for the lower end that box-shaped support is connected with i-shaped roof beam and build node, described box-shaped support and i section steel beam, steel column are welded to connect.
Described be a kind ofly suitable for the lower end that box-shaped support is connected with i-shaped roof beam and build node, described second floor and steel column are welded to connect, and the first floor, trislab and i section steel beam are 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.
