The sleeve is arranged on a connecting area of the square steel column, the T-shaped parts are connected with the sleeve through a first fastening bolt, the H-shaped steel is connected to a pair of vertically distributed T-shaped parts through a second fastening bolt, the H-shaped steel is symmetrically connected to the two sides of the square steel column through the T-shaped parts, and the T-shaped parts are provided with reinforcing ribs. A node of the steel beam is good in seismic behavior and ductility and is a semi-rigid node; and the initial rigidity, axial compression ratio influence and seismic behavior of the steel beam sleeve node are excellent.
Description
Technical field
The present invention relates to technical field of buildings, be specifically related to a kind of high-stability girder steel.
Background technology
Steel work have intensity high, from heavy and light, the advantage such as industrialization degree is high, anti-seismic performance good, sustainable developability is strong.Greatly develop steel structure technique, not only meet the requirement of architectural industrialization, and meet the requirement of green building sustainable development.At present, the U.S., Australia, Japan and other countries are all in the application promoting steel building energetically.
But still there are some technical problems and need deeply to grind the solution that makes internal disorder or usurp in steel work, wherein the type of attachment of bean column node is exactly one of problem to be solved.Bean column node is the significant points ensureing steel work holistic resistant behavior, under normal operating condition, it by beam-to-column joint integrally structure resist the external action such as gravity, wind load; Under geological process, beam end and nodes domains produce plastic strain, form plastic hinge, thus effective absorption and dissipation energy, make overall structure not collapse and topple.Therefore, find that a kind of intensity is high, steel-structure beam-column node that good stability, job site are easy to operate seems particularly urgent and important.
Summary of the invention
The object of the present invention is to provide a kind of high-stability girder steel, solve above-mentioned multinomial defect.
The technical problem that the present invention solves can realize by the following technical solutions: a kind of high-stability girder steel, comprise square steel column, H profile steel, T-shaped and sleeve pipe, described sleeve pipe is arranged on join domain on square steel column, T-shaped is connected on sleeve pipe by fastening bolt one, described H profile steel is connected to by fastening bolt two on T-shaped that distributes for about a pair, and H profile steel is connected to square steel column both sides by T-shaped symmetry.
Preferably, described T-shaped is provided with reinforcing rib, and reinforcing rib is welded on T-shaped side.
Preferably, described T-shaped, square steel column and sleeve pipe installation site be all provided with several bolts hole.
Preferably, described fastening bolt one is monolateral bolt, and fastening bolt two is bilateral bolt.
Preferably, described sleeve pipe and square steel column adopt plug welding to be connected.
Beneficial effect: the good seismic performance of steel beam joint node of the present invention, has good ductility, it is structures with semi-rigid joints; The initial stiffness, ratio of axial compressive force to axial compressive ultimate capacity of section impact, anti-seismic performance etc. of this girder steel casing plug joint are more excellent, so the anti-seismic performance of casing plug joint in the primary structure forms such as composite steel framework, high-level structure and framework Core Walls Structure is superior, reliability is strong; In addition, based on the principle that job site is substantially not on fire, this kind of girder steel can be connected to post side in factory cage plate in advance, and high strength exploitation basic building block is only used in job site, greatly reduce difficulty of construction, the minimizing of weld seam is also for node plasticity serves certain progradation.

Detailed description of the invention
The technological means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with detailed description of the invention, setting forth the present invention further.
As Fig. 1, shown in Fig. 2 and Fig. 3, a kind of high-stability girder steel, comprise square steel column 1, H profile steel 4, T-shaped 3 and sleeve pipe 2, described sleeve pipe 2 is arranged on join domain on square steel column 1, be connected on sleeve pipe 2 by fastening bolt 1 for T-shaped 3, described H profile steel 4 is connected to by fastening bolt 26 on T-shaped 3 that distributes for about a pair, H profile steel 4 is connected to square steel column 1 both sides by T-shaped 3 symmetries, described T-shaped 3 is provided with reinforcing rib 7, reinforcing rib 7 is welded on T-shaped 3 sides, described T-shaped 3, square steel column 1 is all provided with several bolts hole with sleeve pipe 2 installation site, described fastening bolt 1 is monolateral bolt, fastening bolt 26 is bilateral bolt, described sleeve pipe 2 adopts plug welding to be connected with square steel column 1.
Based on said structure design, the good seismic performance of steel beam joint node of the present invention, has good ductility, and it is structures with semi-rigid joints; The initial stiffness, ratio of axial compressive force to axial compressive ultimate capacity of section impact, anti-seismic performance etc. of this girder steel sleeve pipe 2 node are more excellent, so the anti-seismic performance of sleeve pipe 2 node in the primary structure forms such as composite steel framework, high-level structure and framework Core Walls Structure is superior, reliability is strong; In addition, based on the principle that job site is substantially not on fire, this kind of girder steel can be connected to post side in factory cage plate in advance, and high strength exploitation basic building block is only used in job site, greatly reduce difficulty of construction, the minimizing of weld seam is also for node plasticity serves certain progradation.
As known by the technical knowledge, the present invention can be realized by other the embodiment not departing from its Spirit Essence or essential feature.Therefore, above-mentioned disclosed embodiment, with regard to each side, all just illustrates, is not only.Within the scope of the present invention all or be all included in the invention being equal to the change in scope of the present invention.
