Description

Technical Field

[0001] The utility model relates to a beam-column supporting structure of a building main body steel structure. Background Art

[0002] Steel structure building is a new type of building, which consists of load-bearing structures made of columns, beams and other components made of steel. Hot-rolled channel steel, H-shaped steel and the like are often used for steel. The supporting structure composed of beams and columns usually fixes the columns on embedded parts or uses concrete pouring to fix them in a predetermined position, and then hoists the beams of a predetermined length to the predetermined positions of the two adjacent columns. The length of the beam must match the distance between the two adjacent columns to achieve accurate docking and welding or fix them with high-strength bolts. The ends of the beams must match the columns accurately. If the length of the beam is greater than the distance between the adjacent columns, the hoisting cannot be achieved. When the length of the beam is less than the distance between the adjacent columns, the ends of the beams and the column surface cannot be welded or fixed. When a tower crane is used to hoist the beam, the driver is far away from the installation position of the beam and column, making it difficult to hoist it accurately. Assistants are required to use ropes to assist in positioning, making hoisting very difficult. Summary of the invention

[0003] In view of the above shortcomings, the purpose of the utility model is to provide a building main body steel structure beam column support structure that is easy to hoist and assemble.

[0004] To this end, the utility model provides a building main body steel structure beam-column support structure, including columns and beams, wherein the beam is connected between two adjacent columns, and a beam installation area is provided between adjacent columns. The length of the beam is less than the length of the beam installation area. A rigid connecting piece is installed on the beam, and the connecting piece can move relative to the beam in such a way that a gap is provided between the connecting piece and the column surface when the beam is hoisted, and a screw hole is provided on the connecting piece for fixing to the beam, and the other end of the connecting piece is used for fixing to the column.

[0005] Furthermore, the connecting member is provided with a rectangular hole, and the bolt passes through the rectangular hole to install the connecting member on the beam.

[0006] Furthermore, the beam is made of H-shaped steel, the connecting member includes a connecting plate and is arranged on the upper beam flange, and a supporting plate is fixed on the column, and the supporting plate is used to position and support the lower beam flange.

[0007] Furthermore, the column is longitudinally fixed with a connection positioning plate, the connection positioning plate cooperates with the web of the beam to position the web of the beam, and the connection positioning plate and the web are fixed by high-strength bolts.

[0008] Furthermore, the shape of the connecting positioning plate is a T-shaped structure bent at a vertical angle, and the two side plates of the connecting positioning plate at a vertical angle are respectively fixed to the column surface and the web of the beam.

[0009] Furthermore, the connecting plate is L-shaped or T-shaped, and the outer surface of the connecting plate is fixed to the beam flange and the column surface respectively.

[0010] Furthermore, the connection plate is fixedly connected to L-shaped or T-shaped connection blocks on both sides in the width direction of the beam, the outer side of the connection block is flush with the surface of the column, and the connection block is used to be fixed on the column surface.

[0011] Furthermore, a positioning strip is fixed on the column surface, and the positioning strip is used to cooperate with the connecting block to locate the position of the beam.

[0012] Furthermore, the column adopts H-shaped steel and also includes a stiffening plate, which is fixed on the column and cooperates with the beam flange.

[0013] The beneficial technical effects of the utility model are:

[0014] (1) In the beam-column support structure of the building main body steel structure of the utility model, a gap is provided between at least one end of the beam and the column surface, thereby reducing the matching accuracy requirements of the beam and the column during hoisting, thereby reducing the difficulty of hoisting the beam and the column.

DETAILED DESCRIPTION

[0022] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0023] Reference Figure 1 and Figure 2 As shown, the utility model is a building main body steel structure beam-column support structure, including column 1 and beam 2, column 1 and beam 2 are all made of H-shaped steel, beam 2 is connected between two adjacent columns 1, and an installation area of ​​beam 2 is provided between adjacent columns 1, and the length of beam 2 is less than the length of the beam installation area, and a rigid connector is installed on beam 2, and the connector can move relative to beam 2, so that when beam 2 is hoisted, a gap 4 is provided between the connector and column surface 101, and column surface 101 is actually the outer surface of the wing plate of column 1, and screw holes are provided on the connector for fixing with beam 2, and the other end of the connector is used for fixing with column 1. Figure 1 As shown, the beam installation area is between the two columns 1, wherein one end of the beam 2 contacts the column surface 101 and is fixed by a high-strength bolt, and a gap 4 is reserved between the other end of the beam 2 and the other column 1. Of course, in this embodiment, both ends of the beam 2 may also use connectors and a corresponding gap 4 may be reserved between the beam and the column. Figure 2 As shown, the connecting piece includes a connecting plate 3, which includes a rectangular hole 5 and a bolt hole. The bolt passes through the rectangular hole 5 and is fixed to the beam flange 201. The bolt can move in the rectangular hole 5, so that the connecting plate 3 can move relative to the beam end. When hoisting, the connecting plate 3 moves toward the center of the beam 2. After the beam 2 is hoisted in place, the connecting plate 3 is moved to contact the column surface 101, and the connecting plate 3 is fixed to the beam flange 201 through the bolt hole with a high-strength bolt. The other end of the connecting plate 3 is welded to the column surface 101 to complete the installation of the beam 2. By reserving the gap 4, the precision requirements for the matching of the beam 2 and the column 1 are reduced, thereby reducing the difficulty of alignment and assembly when the beam is hoisted.

[0024] In the above embodiment 1, referring to Figure 1As shown, the connecting plate 3 is arranged on the upper beam flange 201, and the support plate 6 is welded and fixed on the column 1. The position of the support plate 6 is used to position and support the lower beam flange 201. During hoisting, in addition to using the support plate 6 to limit the position of the lower beam flange 201, the beam 2 can also be temporarily supported on the support plate 6 to facilitate the welding of the beam 2 and its connecting parts, tightening bolts and other construction, and avoid the influence of shaking when suspended with a sling.

[0025] In the above embodiment 1, referring to Figure 1 As shown, the column 1 is longitudinally fixed with a connection positioning plate 7, and the connection positioning plate 7 cooperates with one side of the web of the beam 2 to position the beam web 202. When hoisting, the beam 2 is slowly moved close to the connection positioning plate 7 and the position of the beam web 202 is positioned, and then the beam 2 is slowly placed on the support plate 6 along the connection positioning plate 7. After the beam 2 is placed in place, the beam web 202 is fixed to the connection positioning plate 7 with high-strength bolts. The bolt holes set on the beam web 202 can be aligned with the bolt holes of the connection positioning plate 7 by positioning one end of the beam 2 with the column surface 101.

[0026] In the above embodiment 1, the connecting plate 3 and the connecting positioning plate 7 are directly welded to the column surface 101, the beam flange 201 transmits the bending moment, and the connecting positioning plate 7 of the beam web transmits the shear force. The bending moment and shear force at the beam end will cause the column flange to be stressed and produce a large deformation. Figure 3 As shown, the embodiment 2 of the utility model is basically the same as the embodiment 1, except that the stiffening plate 8 is welded between the web and the wing plate of the column 1 to cooperate with the beam flange 201 to strengthen the structural strength of the column 1 node, the shape of the connecting positioning plate 7 is processed into a T-shaped structure bent at a vertical angle, and the two side plates of the connecting positioning plate 7 at a vertical angle are respectively fixed to the column surface 101 and the web of the beam 2, the connecting plate 3 is processed into an L shape or a T shape, and the outer surface of the connecting plate 3 is respectively fixed to the beam flange 201 and the column surface 101. By dispersing the force at the end of the beam 2 to the column surface 101, the bending moment and shear force at the end of the beam 2 are avoided from being concentrated in individual positions or areas, thereby improving the strength of the beam-column node.

[0027] Reference Figure 4 and Figure 5As shown, the embodiment 3 of the utility model is basically the same as the embodiment 2, except that the connection plate 3 is fixedly connected to the L-shaped or T-shaped connection blocks 9 on both sides of the beam 2 in the width direction, the outer side of the connection block 9 is flush with the side surface of the column 1, and the connection block 9 is used to be fixed on the column surface 101, and the positioning strip is fixed on the column surface 101, and the positioning strip is used to cooperate with the connection block 9 to locate the position of the beam 2. The width of the beam 2 is generally smaller than the width of the column 1, so the bending moment and force of the beam 2 are concentrated in the middle part of the column surface 101. The connection block 9 of the embodiment 3 can be welded on the column surface 101 and flush with the side surface of the column 1 (the surface adjacent to the column surface 101), and the bending moment and force of the beam 2 are transmitted to the outer column surface 101, which is conducive to improving the strength of the beam-column node and avoiding local deformation due to concentrated force. In addition, a positioning strip 10 is provided on the column 1. When hoisting, the connecting block 9 can cooperate with the positioning strip 10. Since the flange of the beam 2 cooperates with the connecting positioning plate to limit the beam 2 to move only to one side in the width direction, the positioning strip 10 and the connecting block 9 limit the beam 2 to move to the other side, thereby limiting the position of the beam 2 in the width direction. It should be noted that in Example 3, the connection plate 3 and the beam flange 201 can move along the length direction of the beam 2, but cannot rotate. The implementation method can adopt the existing technology, such as setting a rectangular slider in the rectangular hole 5, the slider can slide in the rectangular hole 5, the slider is fixed on the beam flange 201, and limits the rotation of the connection plate 3.

Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
