Description

Technical Field

[0001] This utility model relates to the field of steel structure technology, and in particular to a prefabricated steel structure with a reinforced structure. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. Rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are used. Connecting devices are required during the installation of steel structures.

[0003] In existing technologies, most steel structure connection nodes are directly fixed by bolts, which do not have a reinforcing structure to improve the bending resistance of the steel structure. This results in poor support and stability when the steel structure is bent. Therefore, it is necessary to design a prefabricated steel structure with a reinforcing structure. Utility Model Content

[0004] Therefore, it is necessary to provide a prefabricated steel structure with a reinforced structure to address the aforementioned technical problems.

[0005] To achieve the above objectives, this utility model provides a prefabricated steel structure with a reinforced structure, including nodes, columns, and steel structures. The nodes are installed on the columns, and steel structures are installed around the nodes. Each of the four corners of the node has a slot, and each slot has two limiting slots. The two limiting slots are symmetrically arranged, and limiting blocks are slidably engaged in the limiting slots. Springs are installed in the limiting slots, and a pull rod is slidably connected to the node. The output ends of the springs and pull rods are connected to the limiting blocks. A limiting frame is slidably engaged in the slots, and the limiting frame is slidably engaged with the limiting blocks. Reinforcing ribs are installed on the limiting frames, and a U-shaped block is installed on the end of the reinforcing rib away from the limiting frame. The U-shaped block is configured to cooperate with the steel structure, and two reinforcing ribs connected to adjacent steel structures are installed on the same limiting frame.

[0006] Preferably, the slot is equipped with upper and lower limiting plates, which abut against the limiting frame, and the limiting block is provided with chamfers.

[0007] Preferably, the two U-shaped blocks on the same steel structure are connected by fixing bolts.

[0008] Preferably, the reinforcing rib is provided with a mounting hole, and a screw is threaded into the mounting hole, and the screw is threaded into the limiting frame.

[0009] Preferably, a mounting bracket is installed at the bottom of the node, and the mounting bracket is installed on the column by countersunk bolts.

[0010] Preferably, the steel structure is mounted on the mounting frame by fastening bolts.

[0011] Compared with existing technologies, this technical solution has at least one of the following beneficial effects:

[0012] By inserting the limiting frame into the slot, and fixing it with the reinforcing ribs and U-shaped blocks connected to the limiting frame, a triangular stable structure can be formed between the steel structure and the node. Thus, when the steel structure is subjected to bending stress, the node can generate a certain tensile force on the steel structure through the reinforcing ribs.

[0013] The limiting block and the pull rod work together to allow the limiting frame to be inserted into the slot. The limiting block and the slot work together to limit the limiting frame. Alternatively, the limiting block can be pulled out by the pull rod, so that the limiting frame can be removed, thus achieving convenient installation of the limiting frame.

[0018] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0019] Please see Figures 1 to 3This application provides a prefabricated steel structure with a reinforced structure, including a node 1, a column 2, and a steel structure 3. The node 1 is installed on the column 2, and steel structures 3 are installed around the node 1. The steel structures 3 are suitable for I-beams. Each of the four corners of the node 1 is provided with a slot 4, and two limiting slots 5 are provided in the slot 4. The two limiting slots 5 are symmetrically arranged, and limiting blocks 6 are slidably engaged in the limiting slots 5. Springs 7 are installed in the limiting slots 5. A tie rod 8 is slidably connected to the node 1. The output ends of the springs 7 and the tie rod 8 are connected to the limiting blocks 6. A limiting frame 9 is slidably engaged in the slots 4. The limiting frame 9 is slidably engaged with the limiting blocks 6. A reinforcing rib 10 is installed on the limiting frame 9. A U-shaped block 11 is installed on the end of the reinforcing rib 10 away from the limiting frame 9. The U-shaped block 11 is configured to cooperate with the steel structure 3. Two reinforcing ribs 10 connected on adjacent steel structures 3 are installed on the same limiting frame 9.

[0020] In this embodiment, the pull rod 8 pulls the limiting block 6 to retract and slide within the limiting groove 5, thereby allowing the limiting frame 9 to be installed into the slot 4. After releasing the pull rod 8, the two symmetrically arranged limiting blocks 6 can be precisely engaged within the limiting frame 9. The inner wall of the slot 4 and the two limiting blocks 6 cooperate to clamp the limiting frame 9. As the limiting frame 9 slides into the slot 4, the reinforcing rib 10 drives the two U-shaped blocks 11 to precisely engage with the edges of two adjacent steel structures 3. Thus, the limiting frame 9, the reinforcing rib 10, and the U-shaped blocks 11 together provide stable support for the node 1 and the steel structure 3. Together with node 1 and steel structure 3, they form a triangular stable structure, allowing the steel structure to be balanced by the reinforcing ribs 10 when it is bent under stress. The pull of the tie rod 8 causes the limiting block 6 to drive the spring 7 to contract, so that after the limiting block 6 contracts, the compressed spring 7 can drive the limiting block 6 and tie rod 8 to reset, making the assembly of the limiting frame 9 more convenient. The two reinforcing ribs 10 connecting two adjacent steel structures 3 are installed on the same limiting frame 9. When one steel structure 3 bends, the U-shaped block 11 on the other steel structure 3 can also balance a certain amount of pressure through the action of the limiting frame 9.

[0021] In some embodiments, to further facilitate the insertion of the limiting frame 9 into the slot 4, upper and lower limiting plates 12 are installed in the slot 4, which abut against the limiting frame 9. The limiting block 6 has a chamfer. Thus, the limiting block 6 does not need to be fully retracted into the slot 4; the upper and lower limiting plates 12 abut against the upper and lower edges of the limiting frame 9. The chamfer on the limiting block 6 eliminates the need to pull the pull rod 8 when installing the limiting frame 9, making installation more convenient.

[0022] In some embodiments, to further improve the support stability of the steel structure 3, two U-shaped blocks 11 on the same steel structure 3 are connected by fixing bolts 13. This allows the force to be transferred to the U-shaped block 11 on the other side when one side of the steel structure 3 is subjected to force, via the fixing bolts 13.

[0023] In some embodiments, to facilitate the installation of the reinforcing rib 10, a mounting hole 14 is provided on the reinforcing rib 10, and a screw 15 is threaded into the mounting hole 14. The screw 15 is threaded into the limiting frame 9. Thus, when the steel structure 3 is not installed on one side of node 1, the reinforcing rib 10 can be removed through the screw 15 in the mounting hole 14.

[0024] In some embodiments, to facilitate the installation of node 1 on column 2, a mounting bracket 16 is provided at the bottom of node 1, and the mounting bracket 16 is installed on column 2 by countersunk bolts 17.

[0025] In some embodiments, to facilitate the installation of the steel structure 3, the steel structure 3 is mounted on the mounting bracket 16 by fastening bolts 18.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
