Description

Technical Field

[0001] This utility model relates to the field of factory building frames, specifically a main frame for a steel structure factory building. Background Technology

[0002] With the rapid development of industrialization, steel structure workshops have been widely used in various industrial buildings due to their high strength, fast construction speed, and high flexibility.

[0003] Current steel structure factory frames often require extensive welding to connect various components. This not only increases construction difficulty and time costs but also can affect structural safety due to inconsistent welding quality. Furthermore, the connections between components are often relatively fixed, making it difficult to flexibly adjust them according to actual needs. This limits the applicability and scalability of the factory building in different scenarios. Utility Model Content

[0004] To overcome the above-mentioned shortcomings, this utility model provides a main frame for a steel structure factory building.

[0005] The technical solution adopted by this utility model is as follows:

[0006] A main frame for a steel structure factory building includes a lower frame and an upper frame above it. Both the lower and upper frames are rectangular. Connecting blocks 1 are fixedly connected to the top four corners of the lower frame, and short tubing, which is square-shaped, is fixedly connected to the bottom four corners of the upper frame. Several connecting columns are located between the connecting blocks 1 and the short tubing, and these columns are sequentially connected end-to-end. A slot 1 is formed at the bottom of each connecting column, and a connecting block 2 is fixedly connected to the top of each column. The lowest connecting column slides into the outer wall of the connecting block 1 through the slot 1. The slots 1 of the upper connecting columns sequentially fit into the outer walls of the connecting blocks 2 of the lower connecting columns. The connecting block 2 of the highest connecting column slides into the short tubing. Connecting holes 1 are formed at the bottom of the left and right side walls of each connecting column, and a connecting hole 2 is formed in the middle of the right side wall of each connecting block 2. The connecting hole 2 is a through-hole. Connecting block two, with connecting hole one corresponding to connecting hole two, a sleeve plate fixedly connected to the middle of the outer wall of the connecting column, connecting block three fixedly connected to the front and rear sides and left and right sides of the outer wall of the sleeve plate, connecting hole three opened in the middle of the side wall of connecting block three, a reinforcing column between two adjacent sleeve plates on the left and right and front and rear, a slot two opened at both ends of the reinforcing column, the two ends of the reinforcing column respectively connected to connecting block three on the two sleeve plates through slot two, connecting hole four opened on the side wall of slot two, connecting hole four corresponding to connecting hole three, the outer wall of the reinforcing column has a side plate, the bottom of the side plate is fixedly connected to the bottom of the side wall of the reinforcing column, pins are inserted at both ends of the outer wall of the side plate, one end of the pin is inserted into connecting hole three and connecting hole four, the other end of the pin is slidably sleeved with a spring, the two ends of the spring are fixedly connected to the other end of the pin and the outer wall of the side plate respectively.

[0007] Bolt 1 is inserted into the left side wall of connecting block 1. The right end of bolt 1 passes through the connecting hole 1 between connecting block 1 and the bottom connecting post. Nut 1 is threaded onto the outer wall of the right end of bolt 1. The left side wall of nut 1 abuts against the right side wall of the bottom connecting post. Bolt 2 is inserted into the left side wall of the short pipe. The right end of bolt 2 passes through the connecting hole 2 of the top connecting block 2 and the right side wall of the short pipe. Nut 2 is threaded onto the outer wall of the right end of bolt 2. Nut 2 abuts against the right side wall of the short pipe. Bolt 3 is located on the left side of the connection between the connecting post and the adjacent connecting post. Bolt 3 passes through the connecting hole 1 and the connecting hole 2. Nut 3 is threaded onto the outer wall of the right end of bolt 3. Nut 3 abuts against the right side wall of the connecting post.

[0008] The beneficial effects of this utility model are:

[0009] This utility model adopts a splicing process, which can quickly assemble various components together through bolts and slots, greatly improving the installation and splicing efficiency of the frame. It can also select different numbers of connecting columns and reinforcing columns for assembly and adjustment according to the height, span and other requirements of the factory building, and has a high degree of flexibility.

[0010] By using bolted connections and sleeves, the use of welding is reduced, thereby lowering the cost and risks associated with welding work.

[0011] Because the frame uses a splicing process, the construction and dismantling of the factory building becomes easier and faster. When dismantling is required, simply loosen the bolts and other connecting parts to disassemble the frame into individual components, which facilitates transportation and reuse.
