Description

Technical Field

[0001] The invention relates to the field of steel structure connecting pieces, in particular to an adjustable steel structure connecting member. Background Art

[0002] As one of the main components of steel structure buildings, H-shaped steel is often used as column beams and frame beams due to its excellent structural strength to build a stable and strong steel structure system. However, in the assembly process of steel structure buildings, the vertical node connection of H-shaped steel beams has always been one of the technical difficulties.

[0003] In the vertical node connection of H-shaped steel beams, the following two methods are currently mainly used:

[0004] Method 1: Use welded plates as the connecting parts of the transverse steel beams, and fix the transverse steel beams with bolts; although this method realizes the vertical connection of H-shaped steel beams to a certain extent, the welding quality is often difficult to reach the ideal state due to the influence of various factors such as temperature, materials, and processes during the welding process. It is easy to have defects such as weld cracking, slag inclusions, and lack of fusion, which affects the strength and stability of the connection. In addition, the amount of on-site work is large: welding operations require professional equipment and personnel, and the amount of on-site work is large, the construction period is long, which is not conducive to improving construction efficiency.

[0005] Method 2: Fit a right-angle piece between the H-shaped transverse steel beam and the H-shaped column beam, and then fix the H-shaped transverse steel beam, H-shaped column beam and the right-angle piece with bolts; although this method avoids the problems caused by welding, the fitting area between the right-angle piece and the H-shaped steel beam is limited, and the bolt connection is easily affected by shear force, resulting in insufficient connection strength, which is difficult to meet the connection strength requirements of large steel structure buildings; secondly, the size and shape of the right-angle piece are often difficult to fully match the H-shaped steel beam, and deviations are prone to occur during the assembly process, resulting in looseness or misalignment of the connection, affecting the stability and safety of the connection; and once the connection between the right-angle piece and the H-shaped steel beam is completed, it is difficult to adjust, which cannot meet the flexibility and adjustability requirements of steel structure buildings during the assembly process. Summary of the invention

[0006] In order to make up for the deficiencies of the existing technical problems, the purpose of the present invention is to provide an adjustable steel structure connection member, and the technical problems solved are as follows: how to improve the strength and stability of the vertical node connection of the H-shaped steel beam, and how to enhance the flexibility and adjustability of the vertical node connection of the H-shaped steel beam.

[0007] In order to solve the problems of the prior art, the technical solution of the present invention is as follows:

[0008] The adjustable steel structure connecting component includes a column, and the flange plates on both sides of the column are vertically fitted with a cross beam. Connecting plates are provided at the upper and lower sides of the cross beam where the column is fitted. The two sides of the connecting plate are fixedly connected to the flange plates of the column and the flange plates of the cross beam by transverse bolts and longitudinal bolts respectively. It also includes connecting parts. The connecting parts are symmetrically arranged on both sides of the web of the column. The connecting parts extend horizontally from the center line of the column to the corresponding cross beam to form a U-shaped embedded part. The U-shaped embedded part is embedded between the flange plates on one side of the corresponding cross beam. The two connecting parts on the same side of the web of the column are fitted with each other up and down, and grooves are provided at the joints of the connecting parts. The web of the column is slidably inserted with a positioning screw at the center line between the cross beams. The two ends of the positioning screw are respectively slidably inserted between the grooves of the two corresponding connecting parts that fit each other, and the outer sides of the two ends of the positioning screw are threaded nuts.

[0009] Preferably, the end of the connector is bent and connected to a guide portion on one side away from the column, the guide portion is parallel to the connector body, a slope is provided on the side of the guide portion close to the positioning screw, an extrusion sleeve is provided on the outside of the positioning screw between the guide portions, a chamfer is provided on the side of the extrusion sleeve close to the column, the chamfer fits with the slopes on both sides, and the other side of the extrusion sleeve fits with the corresponding nut.

[0010] Preferably, a C-shaped piece is symmetrically sleeved on the outside of the positioning screw, and the upper and lower ends of the C-shaped piece are respectively slidably connected to the outside of the corresponding connecting piece. The C-shaped piece ensures that the connecting piece is more stable when moving, avoiding loose connection due to shaking or misalignment. In addition, the C-shaped piece also plays a certain limiting role, preventing the connecting piece from excessive movement or misalignment during assembly, thereby improving the accuracy and reliability of the connection.

[0011] Preferably, waist-shaped holes are provided at the top and bottom of the U-shaped embedded part, and the longitudinal bolts penetrate the waist-shaped holes of the U-shaped embedded part and the flange plates of the crossbeam in sequence. The two ends of the longitudinal bolts are fixedly connected to the corresponding connecting plates on the upper and lower sides of the crossbeam, respectively, allowing the U-shaped embedded part to be adjusted in position within a certain range after the longitudinal bolts are assembled, so that the connecting parts have greater flexibility during the assembly process.

[0012] Preferably, L-shaped pieces are flatly attached to both sides of the web of the beam, and the two sides of the L-shaped piece are fixedly connected to the web of the beam and the flange plate of the column by positioning bolts respectively. A serrated groove is provided at the edge of the side where the L-shaped piece fits the column, and a serrated strip is provided on the side of the U-shaped embedded part close to the column, and the serrated strip is meshed with the corresponding serrated groove.

[0013] Preferably, a positioning plate is provided inside the U-shaped embedded part, and circular holes are symmetrically opened on the surface of the positioning plate. One end of the alignment bolt on the side of the L-shaped plate that fits the column is slidably inserted into the corresponding circular hole. The positioning plate is used to ensure that the alignment bolt will not loosen or fall off during the assembly process, thereby improving the firmness of the connection.

[0014] Preferably, a triangular piece is symmetrically fixedly connected inside the U-shaped embedded part, and the triangular piece can prevent the U-shaped embedded part from being deformed or damaged when subjected to force, thereby improving the bearing capacity of the connecting component and ensuring the stability and safety of the steel structure during long-term use.

[0015] Preferably, a reinforcement sheet is fixedly connected between the guide portion and the connector body to ensure that the two remain tightly connected when subjected to force and that connection failure will not occur due to deformation or looseness.

[0016] Compared with the prior art, the advantages of the present invention are as follows:

[0017] 1. The present invention realizes a tight connection between the column and the beam through the U-shaped embedded part, the toothed strip and the extrusion sleeve. This connection not only has high strength, but also can effectively resist external force and deformation, thereby significantly improving the overall stability and safety of the steel structure.

[0018] 2. The design of the connector of the present invention allows for position adjustment during the connection process. By adjusting components such as positioning screws and extrusion sleeves, the position of the connector can be easily changed to meet different assembly requirements and adapt to columns of different sizes. This adjustability makes the steel structure more flexible and adaptable during the assembly process.

[0019] 3. The present invention forms a firm connection method by tightly meshing the toothed strips on the connector with the toothed grooves on the L-shaped sheet. This connection method not only has high strength, but also can effectively prevent the connection from loosening or falling off, thereby significantly enhancing the overall stability of the steel structure.

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] The adjustable steel structure connecting member comprises a column 1, a crossbeam 2 and a connecting piece 6;

[0029] like Figures 1 to 6 As shown, the flange plates on both sides of the column 1 are vertically fitted with the cross beam 2, and the upper and lower sides of the cross beam 2 are provided with connecting plates 3 at the joints with the column 1, and the two sides of the connecting plate 3 are respectively fixedly connected to the flange plates of the column 1 and the flange plates of the cross beam 2 by transverse bolts 4 and longitudinal bolts 5, and also include connecting pieces 6, the connecting pieces 6 are centrally symmetrically arranged on both sides of the web of the column 1, and the connecting pieces 6 are horizontally extended from the center line of the column 1 to the corresponding cross beam 2 to form a U-shaped embedded part 7, and the U-shaped embedded part 7 is embedded between the flange plates on one side of the corresponding cross beam 2, and the two connecting pieces 6 on the same side of the web of the column 1 are fitted with each other up and down, and grooves 8 are opened at the joints of the connecting pieces 6, and the web of the column 1 is slidably inserted with a positioning screw 9 at the center line between the cross beams 2, and the two ends of the positioning screw 9 are respectively slidably inserted between the grooves 8 of the two corresponding mutually fitted connecting pieces 6, and the outer sides of the two ends of the positioning screw 9 are threaded nuts 10;

[0030] The connecting member is mainly used for the assembly between the H-shaped column 1 and the H-shaped beam 2. During the assembly process, the connecting plate 3 is fixed to the specified position of the column 1 by the transverse bolt 4. The connecting plate 3 can provide support and fixing points for subsequent connections. Then, the connecting piece 6 is assembled, and the U-shaped embedding portion 7 of the connecting piece 6 is embedded in the corresponding beam 2. After the U-shaped embedding portion 7 is embedded in the beam 2, the connecting plate 3, the beam 2 and the U-shaped embedding portion 7 are penetrated by the longitudinal bolt 5 to tightly connect the three together, and the positioning screw 9 is used to pass through the groove 8 of the connecting piece 6 that fits each other.

[0031] like Figures 1 to 6As shown, the end of the connector 6 is bent and connected to a guide portion 11 on one side away from the column 1. The guide portion 11 is parallel to the main body of the connector 6. A slope 12 is provided on the side of the guide portion 11 close to the positioning screw 9. An extrusion sleeve 13 is sleeved between the outer side of the positioning screw 9 and the guide portion 11. A chamfer 14 is provided on the side of the extrusion sleeve 13 close to the column 1. The chamfer 14 fits with the slopes 12 on both sides. The other side of the extrusion sleeve 13 fits with the corresponding nut 10.

[0032] By screwing the nut 10, the extrusion sleeve 13 is continuously pushed to extrude the guide portion 11. The chamfer 14 of the extrusion sleeve 13 fits with the inclined surface 12 of the guide portion 11, so that the guide portions 11 are separated from each other and the spacing is increased. Since the guide portions 11 on the connector 6 and the corresponding embedded crossbeam 2 are respectively in different directions on both sides of the positioning screw 9, the extrusion of the extrusion sleeve 13 causes the connector 6 to slide against each other, allowing the U-shaped embedded portion 7 to approach the column 1 and gradually fit.

[0033] like Figures 1 to 6 As shown, a C-shaped piece 15 is symmetrically sleeved on the outside of the positioning screw 9, and the upper and lower ends of the C-shaped piece 15 are respectively slidably connected to the outside of the corresponding connecting piece 6, so that the connecting piece 6 is more stable during the movement. At the same time, it can also ensure that the two connecting pieces 6 always keep in contact with each other to avoid loose connection.

[0034] like Figures 1 to 6 As shown, waist-shaped holes 16 are provided at the top and bottom of the U-shaped embedded part 7, and the longitudinal bolt 5 passes through the waist-shaped hole 16 of the U-shaped embedded part 7 and the flange plate of the beam 2 in sequence. The two ends of the longitudinal bolt 5 are fixedly connected to the corresponding connecting plates 3 on the upper and lower sides of the beam 2 respectively. The waist-shaped hole 16 allows the assembled U-shaped embedded part 7 to have a certain range of movement for subsequent adjustments.

[0035] like Figures 1 to 6 As shown, both sides of the web of the cross beam 2 are flatly attached with L-shaped pieces 17, and the two sides of the L-shaped piece 17 are fixedly connected to the web of the cross beam 2 and the flange plate of the column 1 by positioning bolts 18 respectively, and a toothed groove 19 is provided at the edge of the side where the L-shaped piece 17 is attached to the column 1, and a toothed strip 20 is provided on the side of the U-shaped embedded part 7 close to the column 1, and the toothed strip 20 is meshed with the corresponding toothed groove 19;

[0036] Before making the connection, the cross beam 2 and the column 1 are firstly fixed using the L-shaped piece 17 and the positioning bolts 18 to ensure the stability of the relative position between the two. Secondly, when the U-shaped embedded part 7 is fitted to the column 1, the toothed strip 20 on its surface will engage with the toothed groove 19 of the L-shaped piece 17. This engagement further enhances the connection stability between the column 1 and the cross beam 2.

[0037] like Figures 1 to 6As shown, a positioning piece 21 is provided inside the U-shaped embedded part 7, and circular holes 22 are symmetrically opened on the surface of the positioning piece 21. One end of the alignment bolt 18 on the side of the L-shaped piece 17 that is in contact with the column 1 is slidably inserted into the corresponding circular hole 22. When the U-shaped embedded part 7 is in contact with the column 1, one end of the alignment bolt 18 on the side of the column 1 that is in contact is slidably inserted into the circular hole 22 of the positioning piece 21. The extrusion pressure of the positioning piece 21 can prevent the alignment bolt 18 from loosening, thereby ensuring the firmness of the connection.

[0038] like Figures 1 to 6 As shown, a triangular piece 23 is symmetrically fixedly connected inside the U-shaped embedded part 7. The triangular piece 23 can prevent the U-shaped embedded part 7 from deformation, enhance its strength, and ensure the stability and durability of the connection.

[0039] like Figures 1 to 6 As shown, a reinforcing sheet 24 is fixedly connected between the guide portion 11 and the main body of the connector 6. The reinforcing sheet 24 can enhance the strength between the two, reduce the risk of deformation of the connector 6 when the extrusion sleeve 13 is extruded, and ensure the reliability and safety of the connection.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
