Description

Connecting piece in H-shaped steel building

Technical Field

The invention relates to a connecting component in a steel structure building.

Background

Modern steel structure buildings mainly comprise steel beams, steel columns, steel bridges and other members made of section steel, steel plates and the like. Welding seams and mounting pieces are generally welded between the components or parts, and then the components or parts are connected through bolts and rivets. In the steel structure connection process, the steel beams and the upright columns play the main role and are main bodies for forming the whole steel structure frame building.

The inventor finds that in a high-rise steel structure building, steel beams and steel column sections which are actually selected are large, but the strength of welding seams, welding points and welding connecting pieces which are welded is not balanced with the strength of the sections of welded workpieces, namely, the welded joints are different from the bending resistance of the welded sections, and the welded joints are cracked firstly under the action of force, which is a technical difficulty existing in the steel structure building industry.

In view of the above problems, the inventor proposes a way of using assembled connecting members to connect various beams or columns together through the connecting members, and the bending resistance of each connecting node is equal to the bending resistance of the assembled steel beam or steel column. After all the nodes of the whole building are connected with each other, the bending resistance of the H-shaped steel adopted by the whole building is balanced, and the whole building has stronger resistance to lever force, shearing force, torque force and wave vibration force generated by strong earthquake.

In order to provide a beam column connecting piece in an H-shaped steel building and solve the problems of low welding spot guarantee coefficient and poor overall building rigidity performance in the background technology, the invention provides the following solutions.

The invention adopts the following technical scheme. A connecting member in an H-shaped steel building comprises: the supporting point connecting piece comprises a supporting point connecting piece and a diagonal balancing piece, wherein a horizontal panel of the supporting point connecting piece is provided with a vertical plate rib belt, the plate rib belt is provided with screw holes for connecting an oblique column or a crossed column, a square groove for buckling an H-shaped steel flange plate is arranged below the horizontal panel of the supporting point connecting piece, the square groove is provided with screw holes for connecting the H-shaped steel flange plate, wing plates extend out of the bottom of the square groove to two sides, and the wing plates are provided with screw holes for connecting an oblique beam or a crossed beam; the diagonal balancing piece is made of H-shaped steel, two ends of the diagonal balancing piece are provided with lug plates, and the middle of the diagonal balancing piece is provided with a notch for avoiding cross interference.

According to the connecting piece in the H-shaped steel building, the ear plates at two ends of the diagonal balancing piece are connected with the fulcrum connecting piece through the distance adjusting assembly; the roll adjustment assembly comprises: the adjusting bolt comprises an adjusting bolt, an eccentric shaft and a nut, wherein the center of a screw head of the adjusting bolt is not collinear with the center of the eccentric shaft.

According to the connecting piece in the H-shaped steel building, the distance adjusting bolt is installed on a screw hole of the fulcrum connecting piece, the eccentric shaft is installed on a screw hole of the lug plate, the eccentric shaft is sleeved with the position stopping ferrule, and the outer side of the position stopping ferrule is provided with a screw cap.

According to the connecting piece in the H-shaped steel building, the middle part of the diagonal balancing piece is provided with a screw hole for installing a fastening bolt. When the diagonal balancing piece is used on a vertical surface, a single diagonal column is used, two crossed columns are used as crossed columns, and a plurality of crossed columns are continuously used as continuous crossed columns to form a shearing force wall. When the shear-force-bearing frame is used on a plane, a single oblique beam is used, two crossed beams are used as crossed beams, and a plurality of crossed beams are continuously used as continuous crossed beams to form a shear layer.

The invention has the following beneficial effects:

the connection mode between the central column and the beam of the steel structure building mainly comprises welding connection or welding connection piece connection, and because the welding openings, welding seams, the welding connection piece and the workpieces of the welded beam and the welded column have different bearing capacity and bending resistance, the high-rise steel structure building has poor strong earthquake resistance, which is a technical problem that the building industry has not overcome so far.

The assembled H-shaped steel building has no welding spot on the frame, no welding seam on the beam column, and is an extension of the steel structure building. The butterfly-type swing shock absorber has strong bearing capacity for lever force, shearing force, torque force and wave shock force generated by strong earthquake, and can resist all recorded strong earthquake by matching with the butterfly-type swing shock absorber (the invention patent is disclosed in the invention: the butterfly-type swing shock absorber 201810947786.6), and the dream of the fourth generation building recognized by the building field is realized as a cradle in the middle of the strong earthquake.
