Abstract
The invention discloses a channel steel reinforcing rib connecting node for a square steel tubular column and an H-shaped steel beam. The connecting node comprises the square steel tubular column, the H-shaped steel beam and a channel-shaped reinforcing plate, wherein the two flanges of the channel-shaped reinforcing ribbed plate are butted against the upper flange and the lower flange of the H-shaped steel beam respectively; a web plate is connected with a wall plate of the square steel tubular column; and the height h of the channel-shaped reinforcing ribbed plate is the same as that of the H-shaped steel beam. The square steel tubular column comprises a cold bent square steel tubular column and a hot rolled square steel tubular column; and the H-shaped steel beam comprises a hot rolled H-shaped steel beam and a welded H-shaped steel beam. When matched with the H-shaped steel beam (2), channel steel hot rolling of the channel-shaped reinforcing plate (3) can not be realized, and the welded channel-shaped reinforcing plate can be adopted. The connecting node has the advantages of simple node structure, capability of realizing outward shift of a plastic hinge, no influence on construction of an upper floor, contribution to concrete pouring in a square steel tube and small using amount of steel.
Description
Technical field
The invention belongs to the building structural element technical field; Exactly be quadrate steel pipe column and H shape girder steel channel-section steel stiffening rib connected node; Specifically be applicable to the quadrate steel pipe column of multilayer high-rise steel structure and the connected node of H shape girder steel; It is less to be specially adapted to the quadrate steel pipe column cross section, and the bean column node of internal partition constructional difficulties is set.
Background technology
At present, the principal mode of the connected node of China's quadrate steel pipe column and H shape girder steel has: the internal partition formula, dividing plate is through and the external partition formula.Wherein the internal partition formula is applicable to the square steel pipe that column section is bigger, can not realize because of the limitation of welding the space that for the quadrate steel pipe column that the cross section is less the existence of internal partition simultaneously influences concreting.The through node of dividing plate requires quadrate steel pipe column bottom flange correspondence position on H shape girder steel to block, diaphragm is welded in the relevant position after, weld former square steel pipe again.This node construction is complicated, and weld seam is more concentrated, and influences the post inner concrete and build, and should have less in China.And for the external partition formula, it is external to increase node rigidity that this node is considered internal partition, do not influence concreting, and shortcoming is that steel using amount increases, and influences the moulding of architectural space.
In addition, China is also more to the research of vertical stiffeners node.This node replaces dividing plate through vertical stiffeners is set, and it is external to be about to internal partition.Studying two kinds of more forms is external channel-section steel stiffening rib node and T shape stiffening rib node.Vertical stiffeners is set can drawing on the H section steel beam edge of a wing, pressure be directly passed to the post jamb plate, increased the plane stiffness of square steel pipe, avoid internal partition is not set and the bigger problem of deformity out of plane that causes; Simultaneously, stiffening rib makes the local enhancing of beam section, realizes that the beam plastic hinge moves outward, and node has better anti.The vertical stiffeners node does not influence building of steel pipe inner concrete.But the shortcoming of these two kinds of nodes is constructions that the existence of stiffening rib influences the top floor.
Summary of the invention
The present invention seeks to promote in China for steel work; A kind of bean column node-quadrate steel pipe column and H shape girder steel channel-section steel stiffening rib connected node that is beneficial to Steel Structure Industryization is provided, can either transmits moment of flexure and shearing preferably, satisfy bearing capacity and rigidity requirement; Can practice thrift steel, convenient construction again.
For realizing above-mentioned purpose; Technical scheme of the present invention is:. quadrate steel pipe column and H shape girder steel channel-section steel stiffening rib connected node; Comprise quadrate steel pipe column, H shape girder steel and grooved stiffener, it is characterized in that the put more energy into both wings edge of floor of described flute profile docks with the last bottom flange of H shape girder steel respectively; Web is connected with the quadrate steel pipe column wallboard, and the put more energy into height of height h and H shape girder steel of floor of said flute profile is identical.Said quadrate steel pipe column comprises clod wash quadrate steel pipe column and the square steel column of hot rolling; Said H shape girder steel comprises hot rolled H-shaped beam and welded H shape girder steel.When realizing, can adopt the grooved stiffener of welding with the be complementary hot-rolled steel channel of grooved stiffener of H shape girder steel.
Compared with prior art, the beneficial effect of node of the present invention is:
1, quadrate steel pipe column and H shape girder steel channel-section steel connected node and dividing plate category node have relatively avoided being provided with the problem of internal partition constructional difficulties, simple structure, easy construction among the present invention.Do not influence simultaneously the cast of quadrate steel pipe column inner concrete.
2, quadrate steel pipe column and H shape girder steel channel-section steel connected node among the present invention, wherein the two channel-section steels floor of putting more energy into can be directly passed to quadrate steel pipe column with the drawing of H shape girder steel transmission, pressure, has avoided the bigger problem of deformity out of plane.Simultaneously, strengthened joint structure, be easy to realize that the outer of plastic hinge moves, satisfied the requirement of China, had antihunt action preferably design of node " strong node, weak member ".
3, channel-section steel stiffening rib node compares about node of the present invention and existing T shape stiffening rib and the edge of a wing, and the advantage of the channel-section steel stiffening rib node of quadrate steel pipe column and H shape girder steel is can not influence the construction of top floor.
