Description

A steel structure assembly and connection device Technical Field

[0001] This utility model relates to the field of steel structure installation technology, specifically a steel structure assembly and connection device. Background Technology

[0002] Steel structure is a building structure system that uses steel as the main material. It features high strength, light weight, and modular construction, and is widely used in modern construction engineering. Definition: It is composed of steel beams, steel columns, steel trusses and other components made of steel sections, steel plates, etc., which are connected by welds, bolts or rivets to form an integral structure. The core materials include hot-rolled steel sections (angle steel, I-beams, etc.), cold-rolled thin-walled steel sections and steel pipes, supplemented by rust removal and rust prevention processes (such as galvanizing and coating).

[0003] An investigation revealed that a Chinese utility model patent discloses a steel structure house assembly and connection component (publication number: CN222685694U), which includes a steel frame. An installation mechanism is provided on the outside of the steel frame. The installation mechanism includes connecting steel parts that are fixedly installed on the outer walls of the left and right sides of the steel frame. I-shaped connecting steel bodies are snapped into the inside of the connecting steel parts. Two support rods are fixedly installed on the front and rear inner walls of the steel frame.

[0004] While the aforementioned patent improves the stability of I-shaped connecting steel bodies by using connecting steel components to clamp and support them, during steel structure installation, it is usually necessary to move the steel frame to the vicinity of the steel beam and position it at the designated location by hoisting. However, due to the limitations of the hoisting ropes, it is difficult for workers to make precise fine adjustments to the connection between the steel frame and the steel beam. If the hoisting rope support is directly removed, the large weight of the steel frame may easily cause safety hazards such as tilting or falling. This leads to a dilemma in traditional hoisting processes where efficiency and safety cannot be balanced.

[0005] Therefore, this utility model provides a steel structure assembly and connection device to solve the above problems. Summary of the Invention

[0006] (a) Technical problems to be solved

[0007] This utility model provides a steel structure assembly and connection device, which aims to solve the problems mentioned in the background art.

Multiple rollers are rotatably connected to both the connecting plate and the support frame. A jack for lifting and moving the steel frame is connected to the bottom of the mounting plate. The jack is fixedly installed on the support frame. A limiting mechanism is provided on the mounting plate. The limiting mechanism includes a bidirectional lead screw, symmetrically arranged sliders, and locking blocks. Two locking blocks are respectively fixedly connected to two sliders.

[0024] 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.

[0025] This utility model provides a steel structure assembly and connection device, as shown in Figures 1-5. The device includes a steel beam 1 and a steel frame 2. A support frame 3 is placed on the steel beam 1. Multiple reinforcing plates 12 are fixedly connected to the support frame 3. An mounting plate 7 and a connecting plate 13 are connected to the support frame 3. Multiple rollers 6 are rotatably connected to both the connecting plate 13 and the support frame 3, allowing the support frame 3 to slide on the steel beam 1. A jack 8 for lifting and moving the steel frame 2 is connected to the bottom of the mounting plate 7, and the jack 8 is fixedly installed on the support frame 3. Guide rods 9 are symmetrically fixed at the bottom of the mounting plate 7. The bottom ends of the two guide rods 9 slide through the support frame 3. The steel frame 2 on the mounting plate 7 is moved by the jack 8. The steel frame 2 is easily fine-tuned by the cooperation of the roller 6 and the jack 8. The mounting plate 7 is equipped with a limiting mechanism, which includes a two-way lead screw 16, symmetrically arranged sliders 17 and locking blocks 18. The two locking blocks 18 are fixedly connected to the two sliders 17 respectively. The locking blocks 18 in the upper limiting mechanism of the mounting plate 7 limit the steel frame 2 and prevent the steel frame 2 from slipping off the mounting plate 7.

[0026] The mounting plate 7 has a mounting groove, and the bidirectional screw 16 is rotatably connected in the mounting groove. Both sliders 17 are slidably connected in the mounting groove, and both sliders 17 are threadedly connected to the bidirectional screw 16. The two locking blocks 18 abut against the side wall of the steel frame 2, and the mounting plate 7 abuts against the bottom of the steel frame 2. When in use, rotating the bidirectional screw 16 drives the two sliders 17 to move in opposite directions. The moving sliders 17 drive the locking blocks 18 to move in opposite directions, so that the locking blocks 18 abut against the side wall of the steel frame 2, thus restricting the steel frame 2 on the mounting plate 7.

[0027] The bottom of the connecting plate 13 is rotatably connected to a second screw 14, which passes through the support frame 3 and is threadedly connected to the support frame 3. Limiting rods 15 are symmetrically fixed at the bottom of the connecting plate 13, and the bottom ends of the two limiting rods 15 slide through the support frame 3. In use, the support frame 3 is first suspended on the steel beam 1, so that the rollers 6 on the support frame 3 abut against the top of the steel beam 1. Then, the second screw 14 is rotated to move the connecting plate 13 upward, so that the rollers 6 on the connecting plate 13 abut against the bottom of the steel beam 1, which facilitates the movement of the support frame 3 on the steel beam 1.

[0028] A movable plate 4 is provided above the support frame 3. Limiting plates 11 are symmetrically fixed at the bottom of the movable plate 4. The bottom of the limiting plates 11 slides through the support frame 3. A movable block 10 is fixedly connected to the movable plate 4. A first screw 5 is rotatably connected to the top of the support frame 3. The first screw 5 passes through the movable block 10 and is threadedly connected to the movable block 10. When in use, rotating the first screw 5 drives the movable block 10 to move. The movable block 10 drives the two limiting plates 11 on the movable plate 4 to squeeze the steel beam 1 and perform compression and limitation to prevent the support frame 3 from shifting when the steel frame 2 is installed.

[0029] In summary: During operation, the support frame 3 is suspended on the steel beam 1, so that the rollers 6 on the support frame 3 abut against the top of the steel beam 1. Then, the second screw 14 is rotated to move the connecting plate 13 upward, so that the rollers 6 on the connecting plate 13 abut against the bottom of the steel beam 1, facilitating the movement of the support frame 3 on the steel beam 1. After that, the hoisted steel frame 2 is placed on the mounting plate 7. The double-acting screw 16 is rotated to move the two sliders 17 in opposite directions. The moving sliders 17 move the locking blocks 18 in opposite directions, so that the locking blocks 18 abut against the side wall of the steel frame 2, restricting the steel frame 2 on the mounting plate 7. Finally, the jack 8 is activated to adjust the position of the steel frame 2. After the position is adjusted, the first screw 5 is rotated to move the moving block 10. The moving block 10 moves the two limiting plates 11 on the moving plate 4 to press against the steel beam 1, thus limiting the position and preventing the support frame 3 from shifting during the installation of the steel frame 2.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
