Description

Technical Field

[0001] This utility model belongs to the field of construction equipment technology, specifically relating to a recyclable pressure-bearing steel bracket for steel columns. Background Technology

[0002] In steel column structural systems (such as industrial plants, high-rise steel structure buildings, foundation pit support projects, warehousing and logistics platforms, etc.), the pressure-bearing steel bracket is the core force transmission component that connects the upper load with the steel column, and its function directly determines the overall stability of the structure and the load transmission efficiency. Specifically, the core functions of existing load-bearing steel brackets include: firstly, bearing the vertical loads generated by the superstructure (such as concrete support beams, heavy equipment bases, and secondary beams of floor slabs)—covering static loads (structural self-weight, weight of finishing materials, weight of fixed equipment) and dynamic loads (mechanical vibrations, loads from dense personnel activities). Through its own load-bearing area expansion function, it disperses concentrated loads into distributed loads, transferring them to the steel columns and preventing buckling deformation or weld tearing caused by excessive local stress in the steel columns. Secondly, it assists in strengthening the rigid connection between the steel columns and the superstructure. Through the fixed joints between the brackets and the columns, it enhances the overall structure's resistance to lateral displacement, thus coping with horizontal forces such as wind and seismic loads. Its supporting role in the structural collapse resistance is particularly crucial in high-rise steel structures or seismic fortification areas. However, traditional load-bearing steel bracket installation relies on on-site welding, which makes it difficult to adhere the welds to the steel plates. There are no pre-set positioning benchmarks, some lack reinforcement structures, and the load-bearing area is insufficient, potentially leading to ineffective installation of the load-bearing steel bracket.

[0003] Therefore, it is necessary to propose a recyclable pressure-bearing steel bracket for steel columns to solve this problem. Utility Model Content

[0004] The purpose of this utility model is to provide a recyclable pressure-bearing steel bracket for steel columns, which solves the shortcomings of existing pressure-bearing steel brackets and steel columns that cannot be recycled and reused.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A recyclable pressure-bearing steel support frame for steel columns includes a main body and a concrete support structure. The main body includes lattice columns and fixing components, with the lattice columns fixedly connected to the fixing components. The concrete support structure is fixed to the top of the main body, allowing the concrete support structure to be detachably connected to the lattice columns.

[0006] In some embodiments of this utility model, there are four lattice columns arranged in a square; there are two fixing components, which are respectively fixed at the bottom and middle of the lattice columns.

[0007] Furthermore, the lattice column is an L-shaped angle steel; the fixing assembly is formed by four connecting plates. Using L-shaped angle steel as the lattice column provides better stability and facilitates fixing to the concrete support structure via connectors.

[0008] In this utility model, the concrete support structure is bolted to the main lattice column via connectors.

[0009] Furthermore, the concrete support structure is bolted to the connector, and the connector is bolted to the lattice column.

[0010] Furthermore, the connector is provided in four parts.

[0011] In some embodiments of this utility model, the connector includes a main body and a reinforcing part, which are fixedly connected. The main body is an L-shaped steel plate, and the reinforcing part is a straight plate, forming a triangle. This design facilitates the connector's fit and fixation to the concrete support structure to hold the pressure-bearing steel bracket in place. It also facilitates the disassembly and fixing of the connector to the lattice column, making it easy to recycle. It better withstands the pressure from above the concrete support structure, and the structure is stable. It can better transfer the upper vertical load to the steel column, improve the load-bearing area expansion function of the pressure-bearing steel bracket, enhance the rigid connection with the steel column and concrete support structure, effectively improve stability, and has strong practicality.

[0012] This utility model can be improved by further including a fixing component, which is disposed within the concrete support structure and connected to the connecting component by bolts. The fixing component better secures the concrete support component to the connecting component, resulting in a more stable connection.

[0013] Furthermore, the fastener is fixedly connected to the reinforcing bar.

[0014] Furthermore, the fastener is a steel plate with through holes for bolts to pass through; reinforcing bars are fixedly connected to both the upper and lower surfaces of the fastener. The use of reinforcing bars to fix the fastener further improves the connection stability.

[0015] Furthermore, the fasteners are provided in four parts.

[0016] In this invention, an elastic washer is provided between the bolt nut and the fastener, and the elastic washer is fitted onto the bolt. By providing the elastic washer, loosening can be prevented.

[0017] This utility model has the following beneficial effects: (1) The main body of the recyclable pressure-bearing steel column and the concrete support structure of this utility model are detachably connected, which can fix the concrete support structure and has high connection stability. At the same time, the main body can be recycled and reused.

Reinforcing part. Detailed Implementation

[0021] like Figure 1-7 The steel column shown is a recyclable pressure-bearing steel bracket, including the main body, concrete support structure 3, and connector 4.

[0022] The main body includes a lattice column 1 and a fixing component 2. The lattice column 1 and the fixing component 2 are fixedly connected. The lattice column 1 is an L-shaped angle steel, and there are four of them arranged in a square. There are two fixing components 2, which are fixed at the bottom and middle of the lattice column 1 respectively. Each fixing component 2 is formed by four connecting plates 201.

[0023] The concrete support structure 3 is fixed to the top of the main structure and is connected to the lattice column 1 by bolts 7 via connectors 4. Specifically, the concrete support structure 3 is connected to four connectors 4 by bolts 7, and each connector 4 is connected to the main lattice column 1 by bolts 7. The connector 4 includes a main body 401 and a reinforcing part 402, which are fixedly connected. The main body 401 is an L-shaped steel plate, and the reinforcing part 402 is a straight plate, forming a triangle. The concrete support structure 3 has four fasteners 5, which are steel plates with through holes for the bolts 7 to pass through. Reinforcing bars 6 are fixedly connected to both the upper and lower surfaces of the fasteners 5. The fasteners 5 are connected to the connectors 4 by bolts 7. An elastic washer 8 is provided between the bolt 7 nut and the fastener 5, and the elastic washer 8 is fitted onto the bolt 7. The elastic washer 8 prevents loosening.

[0024] The construction process of this utility model of a recyclable pressure-bearing steel bracket for steel columns is as follows: First, technicians pre-install fixing parts 5 in the concrete support structure 3 at the upper end of the lattice column 1 according to the site conditions. Then, fixing parts 5 can be fixed by pre-embedded steel bars 6501. The fixing method can be welding or binding, depending on the site conditions. After the fixing parts 5 are fixed, high-strength bolts 7 are inserted into their holes, and elastic washers 8 are installed to prevent loosening. Then, high-strength nuts are tightened to fix them. After the high-strength bolts 7 are installed, the on-site technicians can align the opening positions of the horizontal end face pressure-bearing steel plate in the connector 4 according to the position of the high-strength bolts 7 exposed in the concrete support structure 3, and then make holes so that the connector 4 can be connected to the high-strength bolts 7. Then, it is fixed by high-strength nuts. After the connector 4 is connected and fixed to the upper concrete support structure 3, On-site technicians can then make holes on the vertical side of connector 4, passing through the lattice column 1 horizontally to form through holes. Connector 4 and lattice column 1 have holes on their vertical sides, forming the first through hole. The other connector 4 has a second through hole on its opposite vertical sides. The first and second through holes are on the same horizontal line. The other two connectors 4 have a third and a fourth through hole on their left and right vertical sides, also on the same horizontal line. The holes on the front and back sides of connector 4 and lattice column 1 must not be on the same horizontal line to avoid structural conflict with the detachable bolt 7. Then, the screw in the detachable bolt 7 is passed through the first, second, third, and fourth through holes. Finally, the nut is installed and tightened onto the screw part that is outside the bolt. This fixes connector 4 and lattice column 1 into a whole, increasing stability.

[0025] Compared to the traditional installation method of steel column bearing support plates, this utility model adopts a non-destructive connection method using a detachable threaded structure and high-strength bolts 7. The connector 4 can be disassembled or fixed to the lattice column 1 and the concrete support structure 3 through the detachable threaded structure and high-strength bolts 7. This not only facilitates recycling but also better withstands the pressure from above the concrete support structure 3. Furthermore, the structure is stable and can better transfer the upper vertical load to the steel lattice column 1, improve the load-bearing area expansion function of the bearing steel bracket, enhance the rigid connection between the steel lattice column 1 and the concrete support structure 3, effectively improve stability, increase efficiency and quality, and has strong practicality.
