[0015] (3) Beneficial effects

[0016] Compared with the prior art, the present invention provides a support beam for an assembled steel structure building, which has the following beneficial effects:

[0017] This prefabricated steel structure building support beam consists of several groups of beams connected in sequence, assembled by inserting protrusions into storage slots. When the height of the support beam needs to be adjusted, the number of beams can be increased or decreased by simply inserting or removing the protrusions into the corresponding storage slots, thereby flexibly changing the overall height of the support beam. This effectively solves the problem of some existing support beams being difficult to adjust according to demand, and can better adapt to the diverse requirements of support beam height in different building scenarios and construction stages.

[0018] The block connected to the elastic member (composed of a spring and a telescopic rod, providing a more stable structure) fits into the slot on the protrusion. When the protrusion is inserted into the storage slot, the block is first squeezed into the movable slot under the guidance of the inclined surface, compressing the elastic member. Once the protrusion is fully inserted, the block snaps into the slot under the elastic force of the elastic member, achieving a secure connection between the beams. To disassemble, apply appropriate external force to overcome the elastic force of the elastic member and release the block from the slot. This relatively simple operation allows for easy adjustment of the beam assembly state to change height according to actual conditions.

[0019] The fastener design also facilitates assembly and disassembly. The first and second support rings, hinged bases, studs, and nuts work together to connect adjacent beams. When connecting adjacent beams, simply hinge the studs to the hinged bases and tighten the nuts. Assembly is intuitive and convenient, while disassembly simply releases the nuts to separate the adjacent beams, further enhancing the ease of assembly and disassembly of the entire support beam.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-5 , a support beam for an assembled steel structure building, comprising a beam body, a support assembly, a connecting piece and a fastener, wherein the beam body is arranged in several groups evenly, and several groups of the beam bodies are connected in sequence up and down, and the beam body located at the bottom is connected to the supporting assembly, the beam body comprises a shell 1 and a protrusion 2, the protrusion 2 is provided at the bottom of the shell 1, and a receiving groove 20 adapted to the protrusion 2 is further provided at the top of the shell 1, the protrusion 2 is plugged into the receiving groove 20, and the connecting piece is provided in the receiving groove 20, and the connecting piece comprises an elastic piece and a card block 3, a movable groove is provided in the receiving groove 20, and the two ends of the elastic piece are respectively connected to the inner wall of the movable groove and the card block 3, the protrusion 2 is provided with a card groove adapted to the card block 3, and the card block 3 is provided with an inclined surface 4 on the upper and lower sides of one end away from the elastic piece;

[0028] The bottom wall of the beam at the bottom is connected to the support assembly. Then, align the protrusions 2 of one beam set with the receiving slots 20 above the other beam shell 1 to prepare for insertion. The size of the protrusions 2 is compatible with the receiving slots 20 to ensure accurate insertion. As the protrusions 2 gradually insert into the receiving slots 20, the locking blocks 3 of the connector inside the receiving slots 20 come into play.

[0029] The block 3 is provided with inclined surfaces 4 on the upper and lower sides of the end away from the elastic member. As the protrusion 2 is inserted, the side wall of the protrusion 2 will squeeze the inclined surfaces 4 of the block 3. Due to the guiding effect of the inclined surfaces 4, the block 3 will move along the squeezing direction toward the movable groove in the receiving groove 20. At this time, the elastic member (composed of a spring 14 sleeved on the telescopic rod 15. During the telescopic process, the spring 14 and the telescopic rod 15 work together to ensure elastic expansion and contraction while maintaining structural stability) will be compressed, providing space for the block 3 to move;

[0030] When the protrusion 2 is fully inserted into the receiving groove 20, the clamping block 3 will automatically snap into the corresponding clamping groove on the protrusion 2 under the elastic force of the elastic member. Through the cooperation between the clamping block 3 and the clamping groove, the two groups of beams are firmly connected in the vertical direction, so that the upper and lower beams form a relatively stable overall structure. In this way, several groups of beams can be connected up and down in sequence to form a support beam that meets a certain height requirement.

[0031] In actual use, if the height of the support beams needs to be adjusted according to different building requirements, such as in prefabricated steel structures with different storey heights, or when there are new requirements for support height as the construction stage changes, it is only necessary to increase or decrease the connected beams;

[0032] The fasteners include a first support ring 5, a second support ring 6, a hinge seat 7, a stud 8 and a nut 9. The first support ring 5 and the second support ring 6 are respectively provided on the upper and lower sides of the shell 1. A hinge seat 7 is provided above the first support ring 5 on the side away from the shell 1. The second support ring 6 is provided with a notch adapted to the hinge seat 7. The stud 8 is hinged to the hinge seat 7 at the bottom, and a nut 9 is also threaded on the stud 8. After the adjacent beams are initially connected through the protrusion 2, the receiving groove 20 and the connecting piece, in order to further enhance the stability of the connection, fasteners need to be used for reinforcement. During operation, first align the hinge seat 7 above the first support ring 5 on the lower beam shell 1 with the notch of the second support ring 6 on the upper beam shell 1, so that the hinge seat 7 can be embedded in the notch; then, hinge the bottom of the stud 8 with the hinge seat 7, so that the stud 8 can rotate relatively around the hinge point, and then screw the nut 9 onto the stud 8. By rotating the nut 9 (the fins 13 on the left and right sides of the nut 9 are convenient for the operator to hold and apply rotational force), under the action of the thread, the nut 9 gradually moves downward along the stud 8, applying axial extrusion force to the upper and lower beams, so that the first support ring 5 and the second support ring 6 fit tightly together, thereby connecting the adjacent beams more firmly together, ensuring that the entire support beam will not loosen or dislocate between the upper and lower beams when bearing loads, thereby maintaining the stability of the structure.

[0033] The support assembly includes a base plate 10, a support frame 11, and bolts 12. A screw groove is provided below the protrusion 2. A groove is provided below the base plate 10 for receiving the end of the bolt 12. The bolt 12 passes through the base plate 10 and is connected to the protrusion 2. The base plate 10 is also provided with a support frame 11 for supporting the protrusion 2. The base plate 10 is also provided with a reinforcing rib 16 connected to the support frame 11. The bolt 12 is passed through a pre-set hole from the bottom of the base plate 10, and then continues upward through the support frame 11 and screwed into the screw groove below the protrusion 2 until it is tightened. The end of the bolt 12 will be received in the groove below the base plate 10, preventing it from being exposed and affecting the installation of other components or posing a safety hazard. At the same time, the reinforcing rib 16 provided on the base plate 10 strengthens the connection strength between the support frame 11 and the base plate 10, allowing the support assembly to more stably bear the beam body and transmit the load from the upper structure, ensuring reliable support of the entire support beam structure.

[0034] In this embodiment, a friction pad 17 is further provided at one end of the nut 9 close to the hinge seat 7 to ensure the stability of the locking of the nut 9.

[0035] During actual use, a handle is further provided on the side of the shell 1, and the handle includes two groups of symmetrically arranged side panels 18 and a cross beam 19. The two ends of the cross beam 19 are provided with side panels 18 connected to the handle on the left and right. The handle is arranged in two groups symmetrically, and the shell 1 is conveniently carried by the handle.
