Description

A kind of H type Steel Cantilever beam column geometric cross section splicing construction
Technical field
This utility model belongs to technical field of structural engineering, relates to a kind of H type Steel Cantilever beam column geometric cross section splicing construction.
Background technology
China's " seismic design provision in building code " and " Technical Specification for Steel Structure of Tall Buildings " all recommend band cantilever segment beam-column connection form.
At present, the splicing of cantilever girder steel mainly has two ways: one is by using high-strength bolt by cantilever beam web together with Vierendeel girder web splice, is welded together with the Vierendeel girder edge of a wing on the cantilever beam edge of a wing by field joint weldering;Two is by using high-strength bolt and splice plate by together with the edge of a wing of Vierendeel girder and cantilever beam and web splice.These the most conventional splicing forms are designed by the principle of equal strength, have good stress performance, are widely used.The weak point of mode one is, due to needs welding at the construction field (site), is limited by environment and construction site condition, Site Welding workload is bigger, welding quality can not be guaranteed, and easily produces abundant residues stress in commissure, is susceptible to brittle fracture under the load action that moves in circles.The weak point of mode two is, the full bolt connection node of band cantilever beam section beam column, due to the most with bolts, needs to expend substantial amounts of bolt, and in-site installation is complicated, installs inconvenience, increases construction costs.Both modes be all difficult to meet steel construction quickly, the needs of green construction, be unfavorable for reducing construction cost and the reduction of erection time of structure with assembled lightweight steel.
Summary of the invention
For above-mentioned the deficiencies in the prior art, this utility model provides a kind of H type Steel Cantilever beam column geometric cross section splicing construction, and the section part of cantilever beam and Vierendeel girder is staggered to be coordinated, and makes its fluid-tight engagement through Milling Machining.
The technical solution adopted in the utility model is:
A kind of H type Steel Cantilever beam column geometric cross section splicing construction, including girder steel and steel column, girder steel is divided into cantilever beam and Vierendeel girder, cantilever beam is welded on steel column, cantilever beam splices mutually with Vierendeel girder, the splicing section part of cantilever beam and Vierendeel girder is designed to the Z-shaped of reciprocal formula or retangular section structure, splices the close interlaced arrangement of section part;The splice ends of cantilever beam and Vierendeel girder is connected by splice plate.
Splice plate is divided into and is arranged on the splicing upper and lower two pieces of flange splice plate of section part and two blocks of web splice plates front and back.Section junction, the web of girder steel combines closely connection, also combines closely connection in the edge of a wing of girder steel.
Flange splice plate welds mutually with steel beam flange, and on upper and lower flange splice plate and girder steel, lower flange is respectively equipped with several connecting holes, and on upper and lower flange splice plate and girder steel, lower flange connects by several edge of a wing bolts are fixing respectively.The distribution of upper and lower edge of a wing bolt dot center centered by the Z-shaped or intermediate vertical kernel of section of rectangular cross section is symmetrical arranged.
Web splice plate and steel beam web plate are provided with several connecting holes and are connected by several web bolts, web bolt is symmetrical arranged with girder steel by-level longitudinal section for the plane of symmetry, and in the middle of Z-shaped or rectangular cross section, centered by the point on vertical equity line, dot center is symmetrical arranged.
This utility model indicates with General stereoscopic coordinate for direction, is laterally X, is vertically Y, is longitudinally Z.
This utility model beneficial effect is obvious: the welding job of (1) cantilever beam and Vierendeel girder splicing junction is to complete in factory, thus effectively avoids the defect that Site Welding brings;(2) save the usage amount of bolt, reduce on-the-spot installation workload, improve work efficiency, shorten the cycle, reduce construction costs.
