Description

Technical Field

[0001] The present invention relates to the technical field of building steel structures, and more specifically, to an automatic assembly connection structure for a special-shaped reticulated shell steel structure and a construction method thereof. Background Technique

[0002] With its unique spatial force-bearing performance and beautiful shape, the special-shaped reticulated shell steel structure has shown great brilliance in the field of large-span buildings, and is widely used in large stadiums, exhibition centers, and various public cultural buildings, etc.

[0003] The commonly used connection method for the existing special-shaped reticulated shell steel structure is bolt connection. In the actual construction process, the bolt connection requires construction workers to align and tighten the bolts one by one. This process requires a large amount of manpower. Especially in the special-shaped structure, the spatial angles and positions of each member vary greatly, and manual operation is extremely prone to factors such as visual errors and physical exertion, resulting in deviations in the bolt installation positions and making it difficult to ensure the assembly accuracy. Summary of the Invention

[0004] The purpose of the present invention is to provide an automatic assembly connection structure for a special-shaped reticulated shell steel structure and a construction method thereof. Through the characteristics of electromagnetic induction and quick connection of pins, it greatly reduces the large amount of time required for manual alignment and tightening of bolts. During the assembly process, only the bottom frame of the special-shaped reticulated shell needs to be initially positioned through the T-shaped blocks and T-shaped grooves, and the electromagnetic induction system can automatically complete the subsequent connection actions, greatly improving the assembly speed. The electromagnetic induction coil precisely controls the ejection position of the electromagnetic pin to ensure that it can accurately insert into the slot, so as to solve the problems proposed in the above background technique.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] An automatic assembly connection structure for a special-shaped reticulated shell steel structure, including a bottom frame of the special-shaped reticulated shell. An assembly component is arranged on the bottom frame of the special-shaped reticulated shell. A fixing component is arranged at the right-angle connection of four adjacent bottom frames of the special-shaped reticulated shell. Fixing frames that intersect are welded on the upper sides of the four sides of the bottom frame of the special-shaped reticulated shell. Connecting frames are welded between multiple adjacent fixing frames. A support frame is welded between the fixing frame and the upper side of the bottom frame of the special-shaped reticulated shell.

[0007] Preferably, the assembly component includes T-shaped blocks installed on the outer sides of the four sides of the bottom frame of the special-shaped reticulated shell. T-shaped grooves are opened on the outer sides of the four sides of the bottom frame of the special-shaped reticulated shell. The T-shaped blocks and the T-shaped grooves are symmetrically arranged.

[0008] Preferably, the T-shaped blocks and the T-shaped grooves on the sides of two adjacent bottom frames of the special-shaped reticulated shell cooperate with each other.

[0009] Preferably, electromagnetic induction coils are installed on the outer sides of the four sides of the special-shaped reticulated shell bottom frame, and the electromagnetic induction coils on adjacent two special-shaped reticulated shell bottom frames correspond to each other one by one.

[0010] Preferably, electromagnetic bolts are installed on the upper sides of adjacent two sides of the special-shaped reticulated shell bottom frame. The electromagnetic bolts are electrically connected to the electromagnetic induction coils. Fixing blocks are installed on the upper sides of the other adjacent two sides of the special-shaped reticulated shell bottom frame. A slot matching with the electromagnetic bolt is opened on one side of the fixing block.

[0011] Preferably, the fixing assembly includes a fixing plate arranged below the right-angle connection of the four special-shaped reticulated shell bottom frames. Four sliding grooves are opened on the upper side of the fixing plate. Fixing bolts penetrating above the sliding grooves are arranged at the bottom of the fixing plate.

[0012] Preferably, a slider is slidably matched with the inner wall of the sliding groove. A limiting block is installed on the side of the slider. A limiting groove slidably matched with the limiting block is opened on the inner wall of the sliding groove. A through hole matching with the fixing bolt is opened on the upper side of the slider.

[0013] Preferably, a connecting block is installed on the upper side of the slider. A limiting plate located above the special-shaped reticulated shell bottom frame is installed on the top of the connecting block. Connecting grooves matching with the connecting block are opened at the four corners of the inner wall of the special-shaped reticulated shell bottom frame. Thread grooves threadedly matched with the fixing bolts are opened at the bottoms of the four corners of the special-shaped reticulated shell bottom frame.

[0014] A construction method of an automatic assembling and connecting structure for a special-shaped reticulated shell steel structure includes the automatic assembling and connecting structure of the special-shaped reticulated shell steel structure, and the specific operations are as follows:

[0015] During construction, when assembling the special-shaped reticulated shell steel structure, by using the cooperation of the T-shaped block and the T-shaped groove, the sides of adjacent two special-shaped reticulated shell bottom frames can be initially aligned. At this time, the electromagnetic induction coils play a role. After the corresponding electromagnetic induction coils on adjacent two special-shaped reticulated shell bottom frames are electrified, magnetic fields are induced with each other, thereby triggering the electromagnetic bolts to work. The electromagnetic bolts pop out under the magnetic force generated by electrification and are inserted into the slots opened on one side of the fixing block, completing the fixed connection of the sides of adjacent special-shaped reticulated shell bottom frames;

[0016] A fixing plate is provided below the right-angle connection of the four special-shaped reticulated shell bottom frames. The fixing bolt passes through the bottom of the fixing plate to above the sliding groove. The slider can slide in the sliding groove, and the limiting block on the side of the slider slides in the limiting groove, playing a role in guiding and preventing the slider from disengaging from the sliding groove. After adjusting the position of the slider in the sliding groove, the fixing bolt passes through the through hole opened on the upper side of the slider and is screwed tightly with the threaded groove at the bottom of the four corners of the special-shaped reticulated shell bottom frame. At this time, the connecting block installed on the upper side of the slider is embedded into the connecting groove opened at the four corners of the inner wall of the special-shaped reticulated shell bottom frame, and the limiting plate at the top of the connecting block is located above the special-shaped reticulated shell bottom frame, fixing and limiting the special-shaped reticulated shell bottom frame simultaneously from the bottom and the side, ensuring the stability of the four special-shaped reticulated shell bottom frames at the right-angle connection.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] Through the characteristics of electromagnetic induction and quick connection of the plug pin, the present invention greatly reduces the large amount of time required for manual alignment and tightening of bolts. During the assembly process, the construction personnel only need to initially position the special-shaped reticulated shell bottom frame through the T-shaped block and the T-shaped groove, and the electromagnetic induction system can automatically complete the subsequent connection actions, greatly improving the assembly speed and shortening the construction period. The electromagnetic induction coil precisely controls the ejection position of the electromagnetic plug pin to ensure that it can accurately insert into the slot. At the same time, the fixing component, through precise mechanical structures such as the sliding groove, the limiting block, and the threaded fit, ensures the position accuracy of the special-shaped reticulated shell bottom frame at the right-angle connection.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1-5 , the embodiment of the present invention provides an automatic assembly and connection structure for a special-shaped reticulated shell steel structure, including a special-shaped reticulated shell bottom frame 1, an assembly component 2 is arranged on the special-shaped reticulated shell bottom frame 1, a fixing component 3 is arranged at the right-angle connection of four adjacent special-shaped reticulated shell bottom frames 1, fixing frames 4 intersecting with each other are welded on the upper sides of the four sides of the special-shaped reticulated shell bottom frame 1, a connecting frame 5 is welded between adjacent fixing frames 4, and a support frame 6 is welded between the fixing frame 4 and the upper side of the special-shaped reticulated shell bottom frame 1. The assembly component 2 includes T-shaped blocks 201 installed on the outer sides of the four sides of the special-shaped reticulated shell bottom frame 1, T-shaped grooves 202 are opened on the outer sides of the four sides of the special-shaped reticulated shell bottom frame 1, the T-shaped blocks 201 and the T-shaped grooves 202 are symmetrically arranged, and the T-shaped blocks 201 and the T-shaped grooves 202 on the sides of two adjacent special-shaped reticulated shell bottom frames 1 are matched with each other. Electromagnetic induction coils 204 are installed on the outer sides of the four sides of the special-shaped reticulated shell bottom frame 1, and the electromagnetic induction coils 204 on two adjacent special-shaped reticulated shell bottom frames 1 correspond one by one. Electromagnetic bolts 203 are installed on the upper sides of two adjacent sides of the special-shaped reticulated shell bottom frame 1, the electromagnetic bolts 203 are electrically connected to the electromagnetic induction coils 204, fixed blocks 205 are installed on the upper sides of the other two adjacent sides of the special-shaped reticulated shell bottom frame 1, and a slot 206 matching the electromagnetic bolts 203 is opened on one side of the fixed block 205.

[0027] Implementation process: When assembling the special-shaped reticulated shell steel structure, by utilizing the cooperation between the T-shaped block 201 and the T-shaped groove 202, the sides of adjacent two special-shaped reticulated shell bottom frames 1 can be preliminarily aligned. At this time, the electromagnetic induction coil 204 comes into play. After the electromagnetic induction coils 204 on the adjacent two special-shaped reticulated shell bottom frames 1 that correspond to each other are electrified, magnetic fields are induced with each other, thereby triggering the electromagnetic bolt 203 to work.

The fixing bolt 303 penetrates through the bottom of the fixing plate 301 to the upper side of the sliding groove 302. The slider 304 can slide in the sliding groove 302, and the limiting block 305 on the side of the slider 304 slides in the limiting groove 306, playing a role in guiding and preventing the slider 304 from disengaging from the sliding groove 302. After adjusting the position of the slider 304 in the sliding groove 302, the fixing bolt 303 is passed through the through hole 307 opened on the upper side of the slider 304 and is threadedly fitted and tightened with the threaded grooves 311 at the bottoms of the four corners of the special-shaped reticulated shell bottom frame 1.
