Description

Technical Field

[0001] This invention relates to the field of steel structure technology, specifically to an insert-type connection structure for steel columns in steel structures. Background Technology

[0002] With the development of the construction industry, the application of steel structure buildings is becoming increasingly common. Compared with traditional concrete pouring, steel structure buildings use steel plates or sections instead of reinforced concrete, resulting in higher strength, better earthquake resistance, and significantly reduced construction time due to the ability to manufacture components in factories and install them on-site. The reusability of steel also greatly reduces construction waste, making it more environmentally friendly. Steel structure engineering is gradually expanding from industrial buildings with large spans, multi-story or high-rise buildings, and high requirements for heat resistance to civil buildings.

[0003] The installation of steel columns in steel structure engineering can be divided into embedded, inserted, exposed, and encased types. Inserted steel columns are installed by leaving a socket in the foundation, inserting the column, and fixing the column between the column and the foundation socket by pouring fine aggregate concrete. Traditionally, steel columns are temporarily fixed with steel wedges before pouring fine aggregate concrete, which takes a long time and the overall stability after pouring needs to be improved. Vibration and shaking can easily cause the connection to loosen. Therefore, those skilled in the art provide an inserted connection structure for steel columns in steel structures to solve the problems mentioned in the background. Summary of the Invention

[0015] (III) Beneficial Effects

[0016] This invention provides an insert-type connection structure for steel columns in steel structures. It has the following advantages:

[0017] 1. In this invention, by setting up an upper connecting structure and fixing extension connecting frames to the four side walls of the upper connecting column, the crossbars of the steel structure can be installed and positioned more quickly, thereby improving the overall installation efficiency.

[0018] 2. In this invention, by setting a lower connection structure, the positions of the two lower pressure blocks inside the two lower pressure grooves can be adjusted according to the depth of the installation pit during use. At the same time, by setting the shape of the two lower pressure blocks to trapezoidal, they can better fit on both sides of the lower connection column during installation. As the screws are tightened, the lower ends of the two lower pressure blocks are driven into the concrete, thereby increasing the contact area on both sides and making the stability better during installation.

[0019] 3. In this invention, by setting a fastening structure, the entire assembly is placed inside the foundation pit during use. After measuring its horizontal and verticality, concrete is poured inside. Then, by tightening the nut, the nut rotates along with the screw rod, thereby adjusting the height of the lower pressure plate inside the lower connecting column. Subsequently, when the lower ends of the four insert rods contact the side wall of the truncated cone, the connection angle of the four insert rods changes, becoming inclined. By screwing the lower pressure plate to the upper end of the truncated cone, it is installed in place. The four insert rods are distributed in four directions, improving the overall stability and effectively preventing displacement and tilting when subjected to vibration.

The four side walls of the four extension connecting frames 103 have multiple second mounting holes 105, which allows for faster installation and positioning of the crossbars of the steel structure, improving the overall installation efficiency.

[0032] The lower connecting structure 3 includes a lower connecting column 304. A lower pressing groove 306 is provided at the lower end of the center of each of the two side walls of the lower connecting column 304. Lower pressing blocks 303 are slidably connected inside the two lower pressing grooves 306. A connecting hole 305 is provided at the center of the upper end face of each of the two lower pressing blocks 303 near one side edge. The lower ends of the two connecting holes 305 penetrate the upper end face of each of the two lower pressing blocks 303 and lead to their respective lower ends. A fixing bolt 302 is provided inside each of the two connecting holes 305. The lower ends of the two fixing bolts 302 penetrate... Two connecting holes 305 lead to the lower end respectively, and the ends are threaded to the inside of the upper surface of the floor 5. During use, the position of the two lower pressure blocks 303 inside the two lower pressure grooves 306 is adjusted according to the depth of the installation pit. At the same time, by setting the shape of the two lower pressure blocks 303 to trapezoidal, they can better fit on both sides of the lower connecting column 304 during installation. As the screws are tightened, the lower ends of the two lower pressure blocks 303 are driven into the concrete, thereby increasing the contact area on both sides and making the stability better during installation.

[0033] The fastening structure 7 includes a lower pressure plate 706, which is disposed inside the lower connecting structure 3. A threaded hole 705 is provided at the center of the upper end face of the lower pressure plate 706. A fixed crossbar 701 is provided at the upper end of the lower pressure plate 706. A connecting rod 708 is movably connected at the center of the lower end face of the fixed crossbar 701. A nut 707 is fixedly connected to the lower end of the connecting rod 708.

Movable grooves 703 are respectively provided at the center of the lower end face of the lower pressure plate 706 near four quadrant points. Inserted rods 704 are respectively provided inside the four movable grooves 703.

A frustum 711 is provided at the lower end of the center of the inner sidewall of the lower connecting structure 3. A fixed connection is provided on the sidewall of the frustum 711. Four fixed rods 710 are connected, and the other ends of the four fixed rods 710 are fixedly connected to the inner wall of the lower connecting structure 3 in a cross manner. Restriction grooves 709 are respectively set at the center of the two inner walls of the lower connecting structure 3 on both sides of the lower pressure plate 706. In use, the whole is placed inside the foundation pit, and after measuring its horizontal and verticality, concrete is poured inside. Then, the nut 707 is turned by tightening the nut 707 to rotate the screw 702, thereby adjusting the height of the lower pressure plate 706 inside the lower connecting column 304. Then, when the lower ends of the four rods 704 contact the side wall of the frustum 711, the connection angle of the four rods 704 changes and becomes inclined. When the lower pressure plate 706 is screwed to the upper end of the frustum 711, it is installed in place. The four rods 704 are distributed in four directions to improve the overall stability and effectively prevent displacement and tilting when subjected to vibration.

The lower connecting column 304 has an operation hole 301 at the lower end of the center of the two side walls respectively.

[0035] Working Principle: This application relates to an insert-type connection structure for steel columns. During use, the positions of the two lower pressure blocks 303 within the two lower pressure grooves 306 are adjusted according to the depth of the installation pit. Simultaneously, by setting the shape of both lower pressure blocks 303 to trapezoidal, they can better fit against both sides of the lower connecting column 304 during installation. As tightening increases, the lower ends of the two lower pressure blocks 303 are embedded into the concrete, thereby increasing the contact area on both sides and improving stability during installation. After placing the entire structure inside the pit and measuring its horizontal and vertical alignment, concrete is poured inside. Subsequently, the nut 707 is tightened, causing the nut 707 to move along with the screw 702. The lower pressure plate 706 is rotated to adjust its height inside the lower connecting column 304. Then, when the lower ends of the four insert rods 704 contact the side wall of the frustum 711, the connection angle of the four insert rods 704 changes to an inclined shape. When the lower pressure plate 706 is screwed to the upper end of the frustum 711, it is installed in place. The four insert rods 704 are distributed in four directions to improve the overall stability and effectively prevent displacement and tilting when subjected to vibration. During installation, it can better fit on both sides of the lower connecting column 304. As it is tightened more and more, the lower ends of the two lower pressure blocks 303 are embedded into the concrete, thereby increasing the contact area on both sides and making the stability better during installation.
