Abstract
The utility model discloses a node for connecting a square steel tubular column, an H-shaped steel beam and an L-shaped ribbed plate. The node has a simple structure, is convenient to construct, and does not influence pouring operation of concrete in the square steel tubular column. The node comprises the square steel tubular column, the H-shaped steel beam and the L-shaped ribbed plate, wherein two branches of the L-shaped ribbed plate are butted with the upper flange and the lower flange of the H-shaped steel beam, and are connected with wall plates of the square steel tubular column; the width B of each flange of the H-shaped steel beam 1 is twice the sum of the lengths b1 of the branches of the L-shaped ribbed plate, which are butted with the H-shaped steel beam; the square steel tubular column comprises a cold-bent rectangular square steel tubular column and a hot-rolled square column; and the H-shaped steel beam comprises a hot-rolled H-shaped steel beam and a welded H-shaped steel beam. According to the node for connecting the square steel tubular column, the H-shaped steel beam and the L-shaped ribbed plate, an external reinforced rib replaces an internal partition plate, so that tension and pressure of the beam flanges can be transmitted to the wall of the square steel tubular column by the L-shaped ribbed plate, and the external deformation of the plane of the node is increased; furthermore, the problem that the internal partition plate is difficult to construct can be avoided.
Description
Technical field
The utility model belongs to the building structural element field, specifically is applicable to quadrate steel pipe column and the connected node of H shape girder steel in many high-rise steel structure, and it is less to be specially adapted to the quadrate steel pipe column cross section, and the bean column node of internal partition difficulty 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 utility model purpose is to promote in China for steel work, and a kind of bean column node that is beneficial to Steel Structure Industryization is provided, and can either transmit moment of flexure and shearing preferably, satisfies bearing capacity and rigidity requirement, can practice thrift steel, convenient construction again.
For realizing above-mentioned purpose; The technical scheme of the utility model is: quadrate steel pipe column and H shape girder steel L type floor connected node; Comprise quadrate steel pipe column, H shape girder steel and L type floor, it is characterized in that: two limbs of described L type floor are connected with the quadrate steel pipe column wallboard with the last bottom flange butt joint of H shape girder steel respectively.The L shaped steel one limb length b that docks with it of the flange width B twice of H shape girder steel wherein
1With.Said quadrate steel pipe column comprises clod wash rectangle quadrate steel pipe column and hot rolling square column; Said H shape girder steel comprises the H shape girder steel of hot rolled H-shaped beam and welding; Said L type floor is the angle steel of hot rolling, can't realize but work as the hot rolling L type angle steel that is complementary with H shape girder steel, can adopt the L type stiffener of welding.
Compared with prior art, the beneficial effect of the utility model node is:
1, quadrate steel pipe column and H shape girder steel L type floor connected node adopt the measure of outside stiffening rib to replace internal partition in the utility model, and L type floor can pass to the square steel pipe post jamb with the drawing of flange of beam, pressure, has increased the deformity out of plane of node.Simultaneously can avoid being provided with the problem of internal partition constructional difficulties.Joint structure is simple, and easy construction does not influence the cast of quadrate steel pipe column inner concrete.
2, quadrate steel pipe column and H shape girder steel L type floor connected node in the utility model; It is positioned at the put more energy into setting of floor of totally four L types of bottom flange and both sides on the H shape girder steel; Strengthened node rigidity; Be easy to realize that the outer of plastic hinge moves, satisfy " strong node, weak member " requirement in the design, node has better anti.
3, quadrate steel pipe column is compared with channel-section steel stiffening rib node with existing T shape stiffening rib with H shape girder steel L type floor connected node in the utility model, and L type floor can not influence the construction of top floor, and steel using amount is little.
