Description

Technical Field

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

[0002] Steel structure brackets, as crucial components in building structures for bearing and transferring loads, are widely used in industrial plants, bridges, high-rise buildings, and other fields. Through the combination of a frame structure and brackets, they provide support for equipment, components, or building parts, offering advantages such as high strength and convenient construction. However, traditional steel structure brackets still suffer from the following significant drawbacks in practical applications: Traditional steel structure brackets mostly adopt integral welded structures, with large component sizes that cannot be disassembled, resulting in large space occupation and high transportation costs during transportation, especially in complex terrain or narrow site environments, where transportation difficulties are significantly increased.

[0003] Traditional bracket installation relies heavily on welding, requiring specialized welding equipment and personnel. The construction period is long and highly dependent on weather conditions. The high temperatures and fumes generated during welding not only pose safety hazards but also pollute the environment. Furthermore, the precision of welding connections depends on on-site operations, making it prone to error accumulation and resulting in low assembly efficiency, which is ill-suited to the rapid construction requirements of modern industrialized building projects. Utility Model Content

[0004] (a) Technical issues This utility model provides a modular design, which facilitates transportation, allows for rapid assembly, and effectively improves construction efficiency.

[0005] (II) Technical Content To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: a prefabricated steel structure bracket, including a frame body and a bracket plate fixedly installed on the upper end of the frame body. The frame body is a frame beam structure assembled from four columns and four crossbeams. The upper end of the columns is fixedly connected with a joint assembly for connecting the columns and crossbeams by bolts. Multiple support beams are fixedly installed between two opposite crossbeams by bolts. The bottom of the bracket plate is fixedly connected to the support beams by connecting assemblies. The connecting assemblies are fixedly installed on the bottom of the bracket plate by bolts. The support beams are provided with mounting holes corresponding to the connecting assemblies. The bracket plate is assembled using a split structure.

[0006] Furthermore, the column is made of I-beam, and the bottom of the joint assembly is provided with a slot for inserting the I-beam. The side wall of the slot is fixed to the column by bolts. U-shaped mounting seats are fixed on two adjacent sides of the joint assembly, and the crossbeam is fixed between two opposite U-shaped mounting seats by bolts.

[0007] Furthermore, the connecting assembly includes a groove at the bottom of the tray, a base is bolted inside the groove, a screw is fixed to the lower end face of the base, and the screw passes through the mounting hole and is fixed by a nut.

[0008] Furthermore, a reinforcing rib is fixedly provided at the bottom of the U-shaped mounting base.

[0009] Furthermore, each of the two opposing crossbeams has a U-shaped bracket fixedly mounted on its inner side, and the support beam is fixed between the U-shaped brackets by bolts.

[0010] (III) Technical Effects The advantages of this utility model compared with the prior art are: 1. In this utility model, the main frame is assembled from four columns and four beams. The pallet adopts a split structure assembly. Compared with the traditional integral welded structure, each component can be disassembled into an independent unit, which greatly reduces the transportation volume and lowers the transportation cost.

[0011] 2. The columns and beams are quickly connected via U-shaped mounting brackets and bolts in the connector assembly. The support beam is fixed between the U-shaped brackets, and the support plate is quickly secured to the support beam using screws and nuts in the connecting assembly. The entire assembly process requires no complex welding operations, only bolt and nut tightening, greatly reducing the reliance on professional welding equipment and personnel for on-site construction and significantly shortening the construction cycle.

[0012] 3. The bottom slot of the connector assembly is fixed to the column bolt. The bottom of the U-shaped mounting base is equipped with a reinforcing rib plate, which enhances the strength and stability of the connection between the column and the beam, effectively disperses stress, and avoids stress concentration. The support beam is fixed to the beam through the U-shaped bracket and is tightly connected to the support plate through the connecting assembly to form a stable force-bearing system.

Multiple support beams 6 are fixedly mounted between two opposite crossbeams 4 by bolts. The bottom of the support plate 2 is fixedly connected to the support beams 6 by a connecting assembly 7. The connecting assembly 7 is fixedly mounted on the bottom of the support plate 2 by bolts. The support beams 6 are provided with mounting holes 8 corresponding to the connecting assembly 7. The support plate 2 is assembled with a split structure. U-shaped brackets 15 are fixedly mounted on the inner sides of two opposite crossbeams 4. The support beams 6 are fixedly mounted between the U-shaped brackets 15 by bolts.

[0025] The column 3 is made of I-beams. The bottom of the connector assembly 5 is provided with a slot 9 for inserting the I-beams. The side wall of the slot 9 is fixed to the column 3 by bolts. U-shaped mounting seats 10 are fixed on two adjacent sides of the connector assembly 5. The crossbeam 4 is fixed between two opposite U-shaped mounting seats 10 by bolts.

[0027] The working principle of this utility model is as follows: 1. Frame Construction: The uprights 3 are made of I-beams and are inserted into the slots 9 at the bottom of the connector assembly 5, and secured with bolts to ensure a tight connection between the uprights 3 and the connector assembly 5. The U-shaped mounting seats 10 on the adjacent sides of the connector assembly 5 are used to fix the crossbeams 4. The two ends of the crossbeams 4 are placed between two opposing U-shaped mounting seats 10 and are also secured with bolts, thus forming a frame beam structure composed of four uprights 3 and four crossbeams 4. The reinforcing ribs 14 at the bottom of the U-shaped mounting seats 10 further enhance the strength of the connection between the uprights 3 and the crossbeams 4, distribute stress, and ensure the stability of the frame structure.

[0028] 2.

A threaded rod 13 on the lower end of the base 12 passes through the mounting hole 8 on the support beam 6 and is then tightened with a nut to secure the connection between the pallet 2 and the support beam 6. When the steel structure bracket bears a heavy load, the pallet 2 transfers the load to the support beam 6, which then distributes the load to the crossbeam 4 and the column 3. Finally, the load is transferred to the foundation through the column 3, completing the entire load bearing process.
