Description

Technical Field

[0001] The utility model relates to the technical field of steel structures, in particular to a connecting structure for cruciform and box-shaped steel structure columns. Background Technique

[0002] A steel structure is a structure composed of steel materials and is one of the main building structure types. However, when two main steel structure bodies are connected and installed, a common problem is that the position of the connection may not be firm enough, which may cause the installed main steel structure body to shake easily, thus affecting the stability and strength of the entire structure. This instability may not only endanger the safety of the building but also bring many inconveniences to subsequent use and maintenance; in addition, during the installation process, the installation and disassembly between steel structure columns are often a challenge. Due to the characteristics and weight of the steel structure itself, traditional connection methods usually require complex and cumbersome operations, which not only consume a lot of time but also may lead to low installation efficiency. For occasions that require frequent installation and disassembly, such as temporary buildings or detachable structures, this problem is particularly prominent, greatly reducing its practicability and convenience. Therefore, we have proposed a connecting structure for cruciform and box-shaped steel structure columns. Content of the Utility Model

[0003] The main purpose of the utility model is to provide a connecting structure for cruciform and box-shaped steel structure columns, which can effectively solve the problems in the background technique.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] A connecting structure for cruciform and box-shaped steel structure columns, including a box-shaped column steel structure. Two connecting mechanisms are installed at both the left end and the right end of the box-shaped column steel structure. Between the opposite surfaces of the two upper connecting mechanisms and between the opposite surfaces of the two lower connecting mechanisms, reinforcing plates are fixedly connected together. The outer surfaces of the two reinforcing plates are fixedly connected to the inner wall of the box-shaped column steel structure. Between the opposite surfaces of the two left connecting mechanisms and between the opposite surfaces of the two right connecting mechanisms, mounting frames are fixedly connected together. In the middle of the right frame wall of the left mounting frame and in the middle of the left frame wall of the right mounting frame, positioning grooves are provided. On the upper and lower frame walls of the two mounting frames, two limiting grooves are provided respectively. At the upper and lower ends of the two mounting frames, fixing mechanisms are fixedly connected. Inside the two mounting frames, cruciform column steel structures are installed. On the right part of the outer surface of the left cruciform column steel structure and on the left part of the outer surface of the right cruciform column steel structure, two fixing holes are provided respectively.

[0006] Preferably, the connecting mechanism includes a connecting frame. A reinforcing block is fixedly connected between the middle of the left wall and the middle of the lower wall of the connecting frame. The front and rear parts of the left wall of the connecting frame are both inserted and movably connected with connecting screws. The left ends of the two connecting screws penetrate through the right wall of the box-shaped column steel structure and are fixedly connected with the right end of the reinforcing plate. The right parts of the outer surfaces of the two connecting screws are both threadedly connected with connecting nuts.

[0007] By adopting the above technical solution: The connecting mechanism can strengthen the connection effect between the box-shaped column steel structure and the installation frame, and improve the stability of the installation frame.

[0009] By adopting the above technical solution: The firmness of the connecting frame is improved, and the structural strength of the connecting frame is strengthened, so that the connecting frame is firmly fixed to the installation frame.

[0010] Preferably, anti-slip patterns are engraved on the opposite surfaces of the two installation frames. The positioning groove is arranged in a cross-shaped structure and is clamped with the cross-column steel structure.

[0011] By adopting the above technical solution: The anti-slip patterns can increase the friction between the installation frame and the box-shaped column steel structure, strengthen the connection effect, and the cross-column steel structure can be clamped and positioned through the positioning groove.

[0012] Preferably, the fixing mechanism includes support blocks. There are two support blocks. A forward and reverse screw rod is inserted and movably connected between the middle of the opposite surfaces of the two support blocks through bearings. Adjusting handle bars are fixedly connected to the front end and the rear end of the forward and reverse screw rod. Fixing clamping plates are threadedly connected to the front part and the rear part of the outer surface of the forward and reverse screw rod. Fixed magnetic blocks are fixedly connected to the lower parts of the opposite surfaces of the two fixing clamping plates. The lower ends of the two support blocks are fixedly connected to the upper end of the installation frame.

[0013] By adopting the above technical solution: The fixing mechanism can facilitate the quick disassembly and assembly of the cross-column steel structure.

[0014] Preferably, the two fixing clamping plates are both arranged in a convex structure, and the convex parts of the two fixing clamping plates are respectively slidably connected with the corresponding two limiting grooves. The magnetic poles of the two fixed magnetic blocks are opposite.

[0015] By adopting the above technical solution: The limiting groove plays a limiting role on the fixing clamping plate, improves the stability of the fixing clamping plate, and enables the corresponding two fixed magnetic blocks to be adsorbed and fixed together.

[0017] 1.

Then, through the reinforcement of the reinforcement block and the strengthening of the reinforcing plate, the structural strength of the connection can be improved and the connection effect can be enhanced, thereby improving the firmness of the connection position, strengthening the stability and strength of the entire structure, and also enhancing the safety.

[0018] 2. By setting up a fixing mechanism, by inserting the cruciform column steel structure into the positioning groove, and then rotating the forward and reverse screw rod to drive two fixing clamping plates to move towards the middle, so that both fixing magnetic blocks are inserted into the fixing holes and adsorbed together, and the cruciform column steel structure can be firmly clamped by the two fixing clamping plates, the rapid installation and disassembly of the cruciform column steel structure can be realized, improving the installation efficiency.
