Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, specifically to a prefabricated steel structure support beam. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main building materials. For example, support beams are made of steel and provide structural support for the entire building. In patent number "CN218911753U" entitled "A Steel Structure Support Beam," the process involves first installing the steel beam on the base, then installing the support in the mounting groove, and finally using multiple fastening screws to install the lower mounting plate above the steel beam, ensuring it stably abuts against the top side of the support. The snap-fit ​​groove on another part of the device is then snapped onto the upper mounting plate, and the connection is achieved through welding. The structure is fixed in place, providing support for the vertical steel beam under the action of the supports, and also providing a certain buffer in the vertical direction, thereby improving its seismic performance. The support rods, in conjunction with the rotating pins and linkage gears, achieve stable support for the vertical steel beam, ensuring its vertical stability. By opening a through-hole in the middle plate of the steel crossbeam, the self-weight of the steel crossbeam can be reduced without affecting its overall stiffness. Furthermore, the overall stiffness of the steel crossbeam can be improved by the action of multiple reinforcing plates. However, the above structure still has the following problems in actual use:

[0003] The aforementioned steel structure support beam uses multiple fastening bolts to install the lower mounting plate on top of the steel crossbeam, making the disassembly and installation process quite complicated. It requires the use of tools to tighten the fastening bolts multiple times to complete the installation, which makes it inconvenient to use and time-consuming and labor-intensive.

[0004] Therefore, we proposed that prefabricated steel structure support beams can effectively solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a prefabricated steel structure support beam to solve the problem mentioned in the background art that the disassembly and installation process in the current market is relatively complicated, requiring the use of tools to tighten the fastening screws multiple times to complete the installation, which makes it inconvenient to use and time-consuming and labor-intensive.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated steel structure support beam, including a base, wherein a rod is welded and fixed to the lower surface of the base;

[0007] It also includes: the base is provided with a quick-installation mechanism, which uses a screw to press the trapezoidal block, thereby causing the trapezoidal block to engage with the locking rod and the locking hole, thus achieving the installation effect;

[0008] A support beam body is embedded and installed above the base, and a crossbeam is welded and fixed to the upper end of the support beam body. A reinforcing member is bolted to the lower surface of the crossbeam, and the other end of the reinforcing member is bolted to the outer side of the support beam body.

[0009] A limiting plate is fixed to the lower outer side of the main body of the support beam, and a screw rod passes through the upper surface of the limiting plate. The lower end of the screw rod passes through the upper surface of the base, and the screw rod and the base form a threaded connection. The lower end of the screw rod is in contact with the trapezoidal block.

[0010] Preferably, the trapezoidal block is slidably disposed inside the base, and the inner side of the trapezoidal block is welded and fixed to the locking rod. A return spring is sleeved on the outer side of the locking rod, and the outer end of the return spring is fixedly connected to the trapezoidal block, and the inner end of the return spring is fixedly connected to the base.

[0011] Preferably, the inner end of the clamping rod is engaged with the clamping hole, and the clamping hole is located on the outer side of the main body of the support beam.

[0012] Preferably, a shock-absorbing pad is adhered to the lower surface of the limiting plate.

[0013] Preferably, a shock absorber is fixed to the inner wall of the lower surface of the base, and five sets of shock absorbers are provided, with the upper end of the shock absorber contacting the lower end of the support beam body.

[0014] Preferably, a connecting seat is welded and fixed to the outer side of the main body of the support beam, and the outer end of the connecting seat is connected to the movable shaft of the connecting rod, and the other end of the connecting rod is connected to the movable shaft of the sliding seat.

[0015] Preferably, the sliding seat has an inverted "T" shape, and the sliding seat and the base form a sliding engagement connection. Furthermore, a shock-absorbing spring is fixed to the outer side of the sliding seat, and the outer end of the shock-absorbing spring is fixed to the base.

[0016] Compared with the prior art, the beneficial effects of this utility model are: this prefabricated steel structure support beam not only simplifies the installation process, eliminating the need for repeated tightening of bolts to complete the installation, saving time and effort, but also provides a certain buffering and shock absorption effect against impact forces. This not only protects the main body of the support beam but also improves its stability. The specific details are as follows:

[0017] The trapezoidal block is pressed by the screw, which in turn causes the trapezoidal block to move the locking rod, which then engages with the locking hole, thereby further limiting the main body of the support beam. This makes the installation process simpler and eliminates the need to tighten the screw multiple times to complete the installation, saving time and effort.

[0018] Furthermore, when the screw stops pressing the trapezoidal block, the spring force of the return spring causes the trapezoidal block to reset, causing the trapezoidal block to separate the locking rod from the locking hole, thereby realizing the disassembly of the main body of the support beam, making the disassembly process simple and convenient.

[0019] Furthermore, the triangular structure formed by the reinforcing member, the main body of the support beam, and the crossbeam improves the stability of the connection between the main body of the support beam and the crossbeam, and also enhances the robustness.

[0020] Moreover, the damping pads not only provide shock absorption but also protect the limiting plate, preventing damage to the limiting plate due to vibration. The dampers also provide shock absorption and buffering when the main body of the support beam vibrates.

[0021] Furthermore, when the main body of the support beam moves downward due to vibration, it will drive one end of the connecting rod downward through the connecting seat, causing the connecting rod to drive the sliding seat to slide outward. Through the elastic force of the shock-absorbing spring, it can buffer and dampen the impact force to a certain extent. This not only provides protection for the main body of the support beam, but also improves the stability of the main body of the support beam. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-5 The present invention provides the following technical solution:

[0030] Example 1: To address the problem that the disassembly and installation process in the prior art is complex, requiring multiple tightening of the screw 6 with tools to complete the installation, thus making it inconvenient and time-consuming, the following solution is disclosed: A base 1 is included, with a rod 2 welded and fixed to its lower surface; the base 1 also includes a quick-installation mechanism inside, where the screw 6 presses against the trapezoidal block 7, causing the trapezoidal block 7 to engage with the locking rod 8 and the locking hole 10, thereby achieving the installation effect. A limiting plate 4 is fixed to the lower outer side of the support beam body 3, and the limiting plate 4... A screw 6 passes through the upper surface, and the lower end of the screw 6 passes through the upper surface of the base 1. The screw 6 and the base 1 are connected by a thread. The lower end of the screw 6 is in contact with the trapezoidal block 7. The trapezoidal block 7 is slidably disposed inside the base 1. The inner side of the trapezoidal block 7 is welded and fixed to the clamping rod 8. The outer side of the clamping rod 8 is fitted with a return spring 9. The outer end of the return spring 9 is fixedly connected to the trapezoidal block 7. The inner end of the return spring 9 is fixedly connected to the base 1. The inner end of the clamping rod 8 is engaged with the clamping hole 10. The clamping hole 10 is opened on the outer side of the support beam body 3.

[0031] The lower end of the support beam body 3 is fitted with the upper surface of the base 1. The limiting plate 4 is used to achieve the effect of limiting the installation. Then, the screw 6 is threaded through the limiting plate 4 and the base 1 to form a threaded connection, thus achieving the installation effect. As the screw 6 moves downwards, it also contacts the trapezoidal block 7. The screw 6 presses against the trapezoidal block 7, causing it to move inwards. This causes the trapezoidal block 7 to engage with one end of the fixed clamping rod 8 in the clamping hole 10, thus achieving the limiting effect and further strengthening the connection between the support beam body 3 and the base 1. The connection between the two is strong, and when disassembly is required, simply unscrew the screw 6 so that the screw 6 no longer presses against the trapezoidal block 7. At this time, the elastic force of the return spring 9 will drive the trapezoidal block 7 to return to its original position, causing the trapezoidal block 7 to separate the locking rod 8 from the locking hole 10. Then the support beam body 3 can be separated from the base 1. Moreover, the connecting rod 15 and the sliding seat 16 are detachable, which allows the support beam body 3 to be disassembled. The disassembly and installation process is relatively simple and does not require tightening the screw 6 multiple times to complete the installation, saving time and effort.

[0032] Example 2: Unlike Example 1, this example facilitates buffering and shock absorption of the main support beam 3, thereby extending the service life of the main support beam 3 and providing stability. See details... Figures 1-2 and Figure 5 The lower surface of the limiting plate 4 is bonded with a shock-absorbing pad 5. The inner wall of the lower surface of the base 1 is fixed with a shock absorber 11, and five sets of shock absorbers 11 are provided. The upper end of the shock absorber 11 is in contact with the lower end of the support beam body 3. The outer side of the support beam body 3 is welded and fixed with a connecting seat 14. The outer end of the connecting seat 14 is connected to the movable shaft of the connecting rod 15. The other end of the connecting rod 15 is connected to the movable shaft of the sliding seat 16. The sliding seat 16 has an inverted "T" shaped structure. The sliding seat 16 and the base 1 form a sliding engagement connection. The outer side of the sliding seat 16 is fixed with a shock-absorbing spring 17, and the outer end of the shock-absorbing spring 17 is fixed to the base 1.

[0033] Furthermore, the damping pad 5 not only provides shock absorption but also protects the limiting plate 4. The shock absorber 11 buffers and reduces vibrations generated by the support beam body 3. When the support beam body 3 moves downward due to vibration, it drives the connecting seat 14 downward as well. The downward movement of the connecting seat 14 causes one end of the connecting rod 15 to move downward as well. The connecting rod 15 is connected to the sliding seat 16 as a movable shaft. The sliding seat 16 and the base 1 form a sliding engagement connection, which causes the connecting rod 15 to slide the sliding seat 16 outward. This causes the sliding seat 16 to compress the damping spring 17. The spring force of the damping spring 17 provides a certain buffering and shock absorption effect on the impact force. This not only protects the support beam body 3 but also improves its stability.

[0034] Example 3: Unlike Example 2, this example improves the stability of the connection between the main support beam 3 and the crossbeam 12. See details... Figure 1 A support beam body 3 is embedded and installed above the base 1, and a crossbeam 12 is welded and fixed to the upper end of the support beam body 3. A reinforcing member 13 is bolted to the lower surface of the crossbeam 12, and the other end of the reinforcing member 13 is bolted to the outer side of the support beam body 3.

[0035] The insertion rod 2 facilitates the fixing of the base 1 to the ground. The support beam body 3 and the crossbeam 12 form a complete steel structure support beam. The two sides of the support beam body 3 are bolted with reinforcing members 13, and the other end of the reinforcing member 13 is bolted to the lower surface of the crossbeam 12, which improves the stability of the connection between the support beam body 3 and the crossbeam 12 and enhances the firmness.
