Description

[Technical field]

[0001] The invention relates to the technical field of steel structure buildings, in particular to the technical field of connection structures of I-shaped steel beams and box-shaped steel columns. [Background technology]

[0002] Structural construction is a new type of building system, which uses steel plates and steel sections to replace traditional reinforced concrete. It has the advantages of light weight, high strength, energy saving and low carbon, good earthquake resistance, short construction period, reusability and green environmental protection, and is widely used in places such as water parks. In addition, with the rapid development of the national economy, the concepts of low carbon environmental protection and circular economy have become increasingly popular, and local governments and the construction industry also advocate the vigorous development of steel structure prefabricated buildings.

[0003] For steel structure prefabricated buildings, the connection between I-shaped steel beams and box-shaped steel columns is usually directly connected by ordinary welding, which makes it difficult to control the welding fullness of the nodes. However, as a key part of the structure, the node must not only meet the basic requirements of force, but also be easy to install on site, so as to ensure the safety and reliability of the quality of the I-shaped steel beams and box-shaped steel columns.

[0004] In addition, since the width of the flange of the box-shaped steel column is usually larger than that of the flange of the I-shaped steel beam, if a stiffening plate (i.e., a built-in diaphragm) is not provided in the box-shaped steel column corresponding to the flange of the I-shaped steel beam, the bending moment at the end of the I-shaped steel beam will cause the flange plate of the box-shaped steel column to bend and produce obvious deformation, which cannot meet the requirements of rigid connection. At present, the commonly used construction method of the stiffening plate is to first cut off the box-shaped steel column at the main axis of the cross section of the I-shaped steel beam, weld the stiffening plate at the corresponding position, and then weld the box-shaped steel columns together, which is very inconvenient to construct. [Summary of the invention]

[0005] The purpose of the present invention is to solve the problems in the prior art and to propose a connection structure between an I-shaped steel beam and a box-shaped steel column, which can effectively strengthen the strength around the node of the box-shaped steel column and is simple and convenient to install.

Each of the top support blocks is respectively hinged to the bottom surface of the top support plate, and the top support plate supports the I-shaped steel beam upward.

[0008] Preferably, it also includes a pull-down mechanism, which includes a pull-down angle steel, a steel wire rope, a pull-down support block, a pull-down wire rod and a support foot. The pull-down angle steel is fixed to the positioning sleeve by fasteners, one end of the steel wire rope is fixed to the pull-down angle steel, and the other end is rotatably connected to one end of the pull-down wire rod through the pull-down support block, the other end of the pull-down wire rod is screwed into the threaded blind hole of the support foot, and the support foot is buried underground.

[0009] Preferably, the top support sleeve is located below the positioning sleeve and the top support angle steel, top support screw rod, top support block and top support plate are all arranged on the same side of the box-type steel column as the I-beam steel beam, and the pull-down mechanism and the I-beam steel beam are arranged on opposite sides of the box-type steel column.

[0010] Preferably, a plurality of column holes are provided on the outer wall of the box-type steel column, and a plurality of first through holes, second through holes, third through holes, fourth through holes and fifth through holes are respectively provided on the positioning sleeve, positioning angle steel, top support sleeve, top support angle steel and pull-down angle steel, and the fasteners installed between the box-type steel column, the positioning sleeve and the positioning angle steel, between the box-type steel column, the top support sleeve and the top support angle steel, and between the box-type steel column, the positioning sleeve and the pull-down angle steel are all chemical anchors, one end of the anchor rod of the chemical anchor is glued to the column hole and the other end passes through the positioning sleeve and the positioning angle steel along the first through hole and the second through hole, passes through the top support sleeve and the top support angle steel along the third through hole and the fourth through hole, or passes through the positioning sleeve and the pull-down angle steel along the first through hole and the fifth through hole and is threadedly connected with a nut.

[0011] Beneficial effects of the present invention:

[0012] 1) By setting a positioning sleeve outside the box-shaped steel column and fixing it with fasteners, and then vertically welding one end of the I-shaped steel beam to the positioning sleeve, the positioning angle steel and fasteners are used to realize the secondary connection between the I-shaped steel beam and the positioning sleeve, which can effectively strengthen the strength around the node of the box-shaped steel column, and the installation is simple and convenient, and can also improve the welding fullness to a certain extent, improve the safety of construction and hoisting, and achieve good economic benefits;
