[0002] The splicing structure of steel structure refers to the method of splicing different parts or components together through welding, bolting, etc. to form an overall structure.

[0024] Example

[0025] When the two auxiliary I-shaped steels 3 are fixed to the main I-shaped steel 1, welding is generally used, but it is not easy to disassemble the auxiliary I-shaped steel 3 after welding. Another method is to fix them with multiple bolts, but this fixing method is extremely complicated to operate and has extremely low installation efficiency. It is impossible to quickly install and fix the two auxiliary I-shaped steels 3, which greatly reduces the efficiency of splicing and assembly.

[0026] To do this, see Figure 1-4 The utility model provides a steel structure splicing structure, including:

[0027] A main section steel 1, auxiliary section steels 3 are movably overlapped on both side walls of the main section steel 1, the bottom ends of the auxiliary section steels 3 are movably overlapped on the top ends of the supporting plates 2, and the supporting plates 2 are fixedly connected to the outer sides of the main section steel 1;

[0028] It also includes a fixed structure a4 and a fixed structure b5, which are installed on the main steel section 1 and the two auxiliary steel sections 3. The fixed structure b5 can fix the fixed structure a4 and simultaneously realize the rapid fixation of the two auxiliary steel sections 3 on the main steel section 1, thereby greatly improving the splicing efficiency.

[0029] Among them, the top length of the auxiliary section steel 3 is smaller than the bottom length of the auxiliary section steel 3, because the top of the auxiliary section steel 3 is attached to the outer side of the main section steel 1 and a matching notch is opened. Figure 4 It can be seen in.

[0030] Further as Figure 1-4As shown, it is worth explaining in detail that in order to enable the two ends of the two auxiliary I-shaped steels 3 to be initially and quickly fixed to the outer side of the main I-shaped steel 1, a fixing structure a4 is set, including an insertion strip 42 fixedly connected to the two side walls of the two auxiliary I-shaped steels 3, the vertical cross-section of the insertion strip 42 is a convex structure, and the end of the insertion strip 42 facing the main I-shaped steel 1 is movably inserted in the socket provided at one end of the fixing seat 41, the vertical cross-section of the socket is a convex structure, the fixing seat 41 is fixed to the outer side of the main I-shaped steel 1, and an L-shaped moving rod 43 is movably inserted on the fixing seat 41, and the inclined surfaces a431 provided at the bottom ends of the four L-shaped moving rods 43 are movably connected to the card groove provided on the outer wall of the insertion strip 42, and the top ends of the four L-shaped moving rods 43 are between the top ends of the two auxiliary I-shaped steels 3. The main I-shaped steel 1 is connected by a fixed structure b5, and the fixed structure b5 is also connected to four fixed seats 41. Two symmetrically arranged sliding grooves a are provided on the main I-shaped steel 1. Slide blocks a44 with an I-shaped structure in vertical cross section are slidably connected in the sliding grooves a. Both ends of the slide blocks a44 are fixedly connected to the outer side of the L-shaped moving rod 43. The outer side of the fixed seat 41 is threadedly connected with a hand screw 45, and one end of the hand screw 45 after being locked is pressed against the outer side of the L-shaped moving rod 43. Two symmetrically arranged hand screws 46 are rotatably connected on one side wall of the main I-shaped steel 1 through a bearing seat 461. The hand screws 46 are threadedly connected to the corresponding L-shaped moving rod 43, one end of the hand screw 46 is rotatably connected to the outer side of the fixed seat 41, and the other end is fixedly connected to a handle.

[0031] A transverse channel is provided in the fixing seat 41 to facilitate the movement of the L-shaped moving rod 43 , and the transverse channel is connected to the socket.

[0032] Further as Figure 1-4 As shown, it is worth explaining in detail that, in order to be able to realize the linkage between the top ends of the two auxiliary I-shaped steels 3 and the top end of the main I-shaped steel 1 when the fixing structure a4 is fixed, a fixing structure b5 is set up, including a top plate 51 fixed to the top ends of the two auxiliary I-shaped steels 3, and slots 521 are opened on the two side walls of the two top plates 51, and pins 52 with a vertical cross-section of an inverted "isosceles trapezoidal" structure are movably inserted in the slots 521, and sliders b53 with a vertical cross-section of an I-shaped structure are fixed to the bottom ends of the pins 52, and the sliders b53 are slidably connected to the sliding blocks provided on the top ends of the main I-shaped steels 1. In the groove b, the bottom end of the slider b53 is connected to the top end of the L-shaped moving rod 43. Two symmetrically arranged square through holes 541 are provided on the two top plates 51. The two square through holes 541 are located between the two slots 521. Movable rods 54 are movably inserted in the square through holes 541. The bottom ends of the movable rods 54 are movably inserted into the corresponding inner sides of the fixed seats 41 and are provided with inclined surfaces b542 matching the inclined surfaces a431. A connecting block 543 is fixedly connected to one side wall of the movable rod 54. The bottom ends of the connecting blocks 543 are connected to the top end of the fixed seat 41 through a spring 544.

[0033] Among them, the spring 544 shown in the figure is in a stretched state. When one end of the inclined surface a431 of the L-shaped movable rod 43 moves away from the socket direction, the inclined surface a431 cancels the pressure on the inclined surface b542, and then the movable rod 54 moves downward under the reverse action of the spring 544.

[0034] In summary, when using the splicing structure of the steel structure, the two ends of the two auxiliary I-shaped steels 3 can be simultaneously attached to the outer side of the main I-shaped steel 1, and the inserting strips 42 are respectively inserted into the corresponding sockets provided on the fixing seat 41. After that, the hand screw 46 is rotated by the handle, so that the L-shaped moving rod 43 will move in the direction of the inserting strip 42, and one end of the inclined surface a431 will press the movable rod 54 of the inclined surface b542, so that the movable rod 54 moves up and penetrates into the square through hole 541, and at the same time the L-shaped moving rod 43 is moved to the direction of the inserting strip 42. One end of the inclined surface a431 of the movable rod 43 will be clamped in the groove provided on the outer wall of the insert strip 42. In addition, the L-shaped movable rod 43 drives the pin 52 connected to the top of the slider b53 to be inserted into the slot 521 provided on the outer wall of the top plate 51, thereby realizing linkage fixation, and finally tightening the hand screws 45 respectively, so that the L-shaped movable rod 43 is locked and fixed to prevent it from loosening. In summary, the two auxiliary steel sections 3 can be quickly fixed or disassembled on the main steel section 1, and the installation efficiency is high, and the structural stability after installation is good.
