Abstract
Description
Technical Field
[0001] This utility model belongs to the field of composite steel beam technology, specifically a high-load-bearing composite steel beam that is easy to install. Background Technology
[0002] Composite beams are transverse load-bearing members that combine steel beams and concrete slabs through shear connectors to share the load. They fully utilize the advantages of steel's tensile strength and concrete's compressive strength, resulting in high load-bearing capacity, high stiffness, good seismic and dynamic performance, small component cross-sectional dimensions, and convenient construction. Existing composite beams utilize steel beams in various forms, including I-beams, box girders, steel trusses, and honeycomb steel beams.
[0003] A search revealed Chinese patent application number 202321701535.2, which discloses a composite steel beam with good load-bearing capacity. This patent includes a first steel beam, with a second steel beam connected to its right end. First reinforcing plates are fixedly connected to both the upper and lower sides of the second steel beam. Second reinforcing plates are fixedly connected to the inner walls of both the front and rear sides of the left end of the second steel beam. An arc-shaped snap-fit connector is fixedly connected to one side of each of the second reinforcing plates. Fixing plates are fixedly connected to both the front and rear sides of the inner interior of the right end of the first steel beam, and snap-fit holes are provided on the fixing plates. Connecting grooves are provided on the right end of the first steel beam, on the side where the two fixing plates are close to each other. This patent, through the combined use of the first and second reinforcing plates, the arc-shaped snap-fit connector, the fixing plates, the snap-fit holes, and the connecting grooves, can significantly improve the load-bearing capacity of the steel beam, preventing insufficient load-bearing capacity from causing deformation of the steel beam and affecting normal use, thus improving its practicality.
[0004] Although the aforementioned patent can greatly improve the load-bearing capacity of steel beams and prevent insufficient load-bearing capacity from causing deformation of the steel beams and affecting normal use, in actual use, the composite steel beams connected by elastic components can adapt to structural deformation to a certain extent. However, during long-term use, the composite beams are prone to misalignment due to structural vibration, which leads to a decrease in the overall stability of the composite beams and thus affects the load-bearing capacity. At the same time, the installation and debugging process of the spring components is relatively complex and requires high construction precision, which increases the construction difficulty and time cost, making it difficult to meet the needs of rapid construction in modern buildings.
[0005] Therefore, a high-load-bearing composite steel beam that is easy to install is needed to solve this problem. Utility Model Content
[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a high-load-bearing composite steel beam that is easy to install. This solves the problem that although composite steel beams connected by elastic components can adapt to structural deformation to a certain extent, they are prone to misalignment due to structural vibration during long-term use, leading to a decrease in the overall stability of the composite beam and thus affecting its load-bearing capacity.
[0007] This utility model provides the following technical solution: a high-load-bearing combined steel beam that is easy to install, including a column, a support frame fixedly connected to the surface of the column, an installation frame installed on the top of the support frame, fixing blocks symmetrically fixedly connected to the inner wall of the installation frame, an I-shaped steel beam body snapped into the inside of the installation frame, connecting blocks symmetrically arranged on the inner side of the flange plate of the steel beam body, and the connecting blocks and the steel beam body are integrally formed, fixing holes symmetrically opened on the surface of the connecting blocks, a connecting frame is provided at the other end of the steel beam body, snap-fit grooves are opened on both sides of the connecting frame, and the snap-fit grooves snap into the steel beam body, reinforcing holes symmetrically opened on the surface of the installation frame, threaded bolts rotatably connected to the outer side of the reinforcing holes, a moving groove is opened inside the reinforcing holes, a bolt sleeve is threadedly connected to the surface of the threaded bolt, and the bolt sleeve is slidably connected to the moving groove and snapped into the fixing hole at the corresponding position, a through hole is opened on the surface of the connecting frame, a high-strength bolt is threadedly connected to the inside of the through hole, and the high-strength bolt passes through the fixing hole at the corresponding position and is fixedly connected to the through hole on the other side by a nut.
[0008] The top of the mounting frame and the top of the connecting frame are symmetrically provided with auxiliary holes, and the top of the steel beam is symmetrically provided with auxiliary grooves. The auxiliary holes are slidably connected with auxiliary pins, and the auxiliary pins are engaged with the auxiliary grooves.
[0009] The beneficial effects of this utility model are as follows:
[0010] 1. This utility model provides a convenient-to-install composite steel beam structure through the setting of components such as columns, bearing frames, and mounting frames. The bearing frames are fixed on the columns to provide support for the mounting frames. The mounting frames are used to snap the steel beams together, giving the steel beams a stable basic structure for installation. By utilizing the connecting blocks on the inner side of the steel beam flanges to cooperate with the fixing blocks, reinforcing holes, threaded bolts, and bolt sleeves on the mounting frames, and the connecting frames at the other end of the steel beams are connected by high-strength bolts, the steel beams are firmly installed and connected, improving the overall load-bearing capacity and stability of the composite steel beams.

Detailed Implementation
[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0020] like Figures 1 to 6 As shown, the high-load-bearing composite steel beam of this embodiment includes a column 1, a bearing frame 2 fixedly connected to the surface of the column 1, an installation frame 3 installed on the top of the bearing frame 2, fixing blocks 4 symmetrically fixedly connected to the inner wall of the installation frame 3, an I-shaped steel beam 5 snapped into the inside of the installation frame 3, connecting blocks 6 symmetrically arranged on the inner side of the flange plate of the steel beam 5, and the connecting blocks 6 and the steel beam 5 are integrally formed, fixing holes 7 symmetrically opened on the surface of the connecting blocks 6, a connecting frame 8 is provided at the other end of the steel beam 5, and snap-fit grooves 9 are opened on both sides of the connecting frame 8, and the snap-fit grooves 9 are connected to the steel beam 5. The beam 5 is snapped together. The surface of the mounting frame 3 is symmetrically provided with reinforcement holes 10. The outer side of the reinforcement hole 10 is rotatably connected with a threaded bolt 11. The inside of the reinforcement hole 10 is provided with a moving groove 12. The surface of the threaded bolt 11 is threadedly connected with a bolt sleeve 13. The bolt sleeve 13 is slidably connected to the moving groove 12 and snapped together with the corresponding fixed hole 7. The surface of the connecting frame 8 is provided with a through hole 14. The inside of the through hole 14 is threadedly connected with a high-strength bolt 15. The high-strength bolt 15 passes through the corresponding fixed hole 7 and is fixedly connected to the through hole 14 on the other side by a nut.
[0021] refer to Figure 1 and Figure 2 Auxiliary holes 16 are symmetrically provided on the top of the mounting frame 3 and the two sides of the top of the connecting frame 8. Auxiliary grooves 17 are symmetrically provided on the top of the steel beam 5. An auxiliary pin 18 is slidably connected inside the auxiliary hole 16, and the auxiliary pin 18 is engaged with the auxiliary groove 17.
[0022] In this embodiment, the auxiliary holes 16 at the top of the mounting frame 3 and the connecting frame 8 cooperate with the auxiliary groove 17 at the top of the steel beam 5, and the auxiliary pins 18 are inserted for snap-fit. This plays a role in assisting positioning and strengthening the connection during the installation process, making the position of the steel beam 5 within the mounting frame 3 and the connecting frame 8 more accurate and stable, and further improving the installation accuracy and overall stability of the combined steel beam.
[0023] refer to Figure 2 A limiting cavity 19 is formed in the inner wall of the auxiliary hole 16, and a limiting ring 20 is fixedly connected to the surface of the auxiliary pin 18, and the limiting ring 20 is slidably connected to the limiting cavity 19.
[0024] In this embodiment, the limiting cavity 19 on the inner wall of the auxiliary hole 16 is slidably connected to the limiting ring 20 on the auxiliary pin 18, which limits the sliding of the auxiliary pin 18 and prevents the auxiliary pin 18 from completely disengaging from the auxiliary hole 16 during use. This ensures that the auxiliary pin 18 can always play a role in auxiliary positioning and connection, thereby enhancing the reliability of the composite steel beam structure.
[0025] refer to Figure 2 An auxiliary spring 21 is sleeved on the surface of the auxiliary pin 18, and the auxiliary spring 21 is located between the limiting ring 20 and the limiting cavity 19.
[0026] In this embodiment, the auxiliary spring 21, which is sleeved on the surface of the auxiliary pin 18, is located between the limiting ring 20 and the limiting cavity 19. The auxiliary spring 21 can provide a certain elastic force to the auxiliary pin 18, making it more convenient and flexible in the process of snapping and disassembling. During installation, the elastic force of the auxiliary spring 21 can help the auxiliary pin 18 to be better inserted into the auxiliary groove 17.
[0027] refer to Figure 3 , Figure 4 and Figure 5 The steel beam 5 has anti-misbehavior grooves 22 symmetrically opened at both ends. Anti-misbehavior blocks 23 are fixedly connected to the surface of the bearing frame 2 and the inner wall of the snap-fit groove 9, and the anti-misbehavior blocks 23 are snap-fitted with the anti-misbehavior grooves 22.
[0028] In this embodiment, the anti-mistake grooves 22 at both ends of the steel beam 5 are engaged with the anti-mistake blocks 23 on the surface of the support frame 2 and the inner wall of the snap-fit groove 9, which plays a role in preventing mistakes and ensuring that the steel beam 5 can be installed correctly during installation. This avoids problems such as incorrect installation direction that could lead to the steel beam being installed insecurely or affecting the overall performance of the combined steel beam, thereby improving the accuracy and efficiency of installation.
[0029] refer to Figure 4 and Figure 5 The bottom of the inner wall of the mounting frame 3 and the snap-fit groove 9 is symmetrically fixed with reinforcing strips 24, and the bottom of both ends of the steel beam 5 is symmetrically provided with reinforcing grooves 25, and the reinforcing grooves 25 are snap-fitted with the reinforcing strips 24.
[0030] In this embodiment, the reinforcing strip 24 at the bottom of the inner wall of the mounting frame 3 and the snap-fit groove 9 is snapped into the reinforcing groove 25 at the bottom of both ends of the steel beam 5. This increases the contact area and connection strength between the steel beam 5 and the mounting frame 3 and the connecting frame 8, further improving the load-bearing capacity and stability of the composite steel beam. This allows the steel beam to better transmit force when bearing loads and reduces the possibility of local deformation.
[0031] refer to Figure 6 The top and bottom of the movable groove 12 are symmetrically provided with limiting grooves, and the top and bottom of the bolt sleeve 13 are symmetrically fixedly connected with limiting blocks 26, and the limiting blocks 26 are slidably connected with the limiting grooves.
[0032] In this embodiment, the limiting grooves at the top and bottom of the moving groove 12 are slidably connected to the limiting blocks 26 at the top and bottom of the sleeve 13, which restricts and guides the movement of the sleeve 13, ensuring that the sleeve 13 can slide stably in the moving groove 12 and accurately engage with the fixing hole 7. At the same time, it prevents the sleeve 13 from shifting or tilting when the threaded bolt 11 rotates, thus ensuring the reliability of the reinforced connection.
[0033] refer to Figure 3 The surface of the fixing block 4 is threaded with fixing bolts 27, and the fixing bolts 27 are fixedly connected to the column 1. The bottom of the support frame 2 is fixedly connected with triangular reinforcing ribs.
[0034] In this embodiment, the fixing block 4 is fixedly connected to the column 1 by the fixing bolt 27, making the connection between the mounting frame 3 and the column 1 more secure; the triangular reinforcing ribs at the bottom of the bearing frame 2 enhance the stability of the bearing frame 2, thereby improving the stability and load-bearing capacity of the entire composite steel beam structure.
[0035] The support frame 2 is fixed to the column 1 by the fixing block 4 and fixing bolt 27 to ensure verticality and stability. At this time, check whether the triangular reinforcing ribs are firm to enhance the deformation resistance of the support frame 2. When installing the single-section steel beam 5, first pull the auxiliary pin 18 on the mounting frame 3 upward to retract it into the auxiliary hole 16, and make the limiting ring 20 compress the auxiliary spring 21. Then, align the end of the steel beam 5 with the connecting block 6 with the mounting frame 3. At this time, the anti-fooling groove 22 engages with the anti-fooling block 23 of the support frame 2 and the mounting frame 3 to confirm that the installation direction is correct. Then, align the reinforcing groove 25 with the reinforcing strip 24 at the bottom of the mounting frame 3 and insert it into place. Then, insert the threaded bolt 11 from the reinforcing hole 10 and rotate the threaded bolt 11 to drive the bolt sleeve 13 to slide in the moving groove 12, so that the bolt sleeve 13 engages with the fixing hole 7 of the connecting block 6 to complete the horizontal fixation. Then, release the auxiliary pin. 18. In addition, the reaction force of the auxiliary spring 21 pushes the limiting ring 20 down, so that the auxiliary pin 18 is engaged in the corresponding auxiliary groove 17 on the steel beam 5. Then, the elastic force of the auxiliary spring 21 is used to maintain the positioning. Next, when splicing multiple steel beams 5, first align the connecting frame 8 of the adjacent steel beams 5 with the other end of the installed steel beam 5, so that the snap-fit groove 9 is engaged in the end of the steel beam 5. The anti-fooling groove 22 is engaged with the anti-fooling block 23 on the inner wall of the snap-fit groove 9. Then, the reinforcing groove 25 is aligned with the reinforcing strip 24 at the bottom of the snap-fit groove 9 and inserted into place. At this time, the auxiliary pin 18 needs to be engaged in the corresponding auxiliary groove 17 on the steel beam 5 in the same way as above. Then, the high-strength bolt 15 is passed through the through hole 14 of the connecting frame 8 and the fixing hole 7 of the steel beam 5 and locked with the nut to complete the rigid connection of the two steel beams 5. Repeat the above steps until all steel beams 5 are spliced.
