Description

Technical Field

[0001] The invention relates to the technical field of beam-column connection of assembled steel structure buildings, and in particular to an assembled steel structure connection component. Background Art

[0002] Steel structure building is a new type of building system. It is mainly composed of high-efficiency structural steel and high-efficiency functional materials such as hot-rolled light H-steel, light welded steel, high-frequency welded steel, cold-bent thin-walled steel, thin steel plates and thin-walled steel pipes, and is assembled with various high-efficiency decorative connection materials. It is a light fully assembled steel structure building that can meet the specific use functions and specific space requirements of the building. Compared with traditional concrete buildings, steel structure buildings use steel plates or steel sections instead of reinforced concrete. They are lighter, stronger, and more earthquake-resistant. They are less prone to concentrated damage and fragmentation than masonry structures, which effectively ensures property safety. Existing steel structure building components can be factory-produced, and steel can be cut at the construction site according to the size and length of the house to facilitate on-site installation and fixation with self-tapping screws or bolts, reducing the time spent on concrete construction. However, after the building steel structure connectors are fixed to the wall, when cutting the steel for installation, it is often difficult to install the steel structure due to the installation of the building steel structure. Errors in positioning and inaccurate steel length cutting lead to difficulties in the installation of steel and steel structure connectors. In the prior art, for example, patent number CN211499190U is a kind of steel structure building house that can be quickly connected. The installation position of the steel structure connector is determined by setting a positioning block on the beam, which facilitates the quick connection of the steel structure. The first positioning block and the second positioning block are set on the support block for support and fixation. At the same time, reinforcing ribs are set on the first positioning block and the second positioning block at both ends of the column for support. This can ensure the stability of the connection between the column and the beam, and greatly improve the connection efficiency of the steel structure.

[0003] The prior art solves the problem of difficulty in installation due to errors in the installation and positioning of steel and steel structure connectors when connecting building steel structure connection components. By arranging positioning blocks on the support blocks, it is convenient to quickly position the steel when connecting the steel, so that the installation positions of the steel and the connectors are accurate and the connection is faster. However, when installing the steel and steel structure connectors, the installation speed of the steel and steel structure connectors is not only related to the positioning accuracy of the steel and the connectors, but also to the cut length of the steel, especially when used as indoor building beams for high-altitude installation and connection, The connectors must first be fixed on both sides of the walls inside the house, and then the steel is connected to the steel connectors. Therefore, when cutting the steel, if the cut length of the steel is too long, the steel cannot be fed into the connectors and the steel needs to be re-cut. If the cut length of the steel is too short, the gap between the steel and the connector will be too large, making it difficult to weld the steel and the connector, affecting the connection strength. Even if the appropriate steel length is selected, the connectors on both sides of the steel will be fixed first, resulting in a small installation space for the steel and the connector during installation, making positioning and adjustment inconvenient, affecting the installation speed.

[0004] To this end, a prefabricated building steel structure connection component is proposed. Summary of the invention

[0005] The object of the present invention is to provide a prefabricated building steel structure connection component.

At this time, the left end of the unlocking block 566 abuts against the right end of the welding plate 2. When the unlocking slider 562 moves downward, it drives the unlocking link plate 565 and the unlocking block 566 to move downward. The unlocking block 566 moves to the lower end of the welding plate 2 in the unlocking groove 563. At this time, the right end of the welding plate 2 is unlocked.

[0042] See also Figure 6 to Figure 7 Specifically, the fitting component 7 includes a fitting groove 71, a fitting spring 72, a fitting rack 73, a fitting gear 74, a fitting sleeve 75 and a fitting threaded column 76.

The cooperation here means that when the fitting sleeve 75 rotates forward, the telescopic plate 8 moves to the right under the cooperation of the fitting sleeve 75, the fitting threaded column 76 and the telescopic groove 9.

[0043] Working principle: When connecting the steel material F to the wall E, first fix the connector 1 to the wall E with expansion bolts, and then the operator places the steel material F on the support plate 4 on the side of the connector 1 and pushes it backwards. During the connection process, sufficient gaps are left on both sides of the connector 1 and the steel material F to facilitate the installation of the steel material F. After the steel material F is installed, the welding plate 2 and the telescopic plate 8 on the side of the connector 1 extend out under the action of the fitting component 7, so that the welding plate 2 fits the steel material F, which facilitates the installation of the steel material F while preventing the gap between the steel material F and the welding plate 2 from being too large, resulting in welding difficulties and unstable fixation.

[0044] Specifically, when connecting the building steel material F and the wall E, the operator first drills a hole in the wall E, and then fixes the connecting piece 1 and the wall E with expansion bolts, fixes one set of bolts at each end of the wall E, and then places the two ends of the steel material F on the support plate 4, and pushes the steel material F backward. In the process of the steel material F moving backward, the rear end of the steel material F gradually fits with the unlocking chamfer 561, and gradually pushes the unlocking slider 562 downward along the unlocking chamfer 561. When the unlocking slider 562 moves downward, the unlocking slider 562 is driven to unlock. The locking plate 565 and the unlocking block 566 move downward, and the unlocking block 566 moves to the lower end of the welding plate 2 in the unlocking groove 563. At this time, the right end of the welding plate 2 is unlocked, and the welding plate 2 moves a certain distance to the left under the action of the buffer spring 642, so that when the subsequent welding plate 2 is fitted with the steel F, the distance between the welding plate 2 and the steel F can be shortened in advance to reduce bumps and wear. After the steel F is installed, when the welding plate 2 is fitted with the steel F, the buffer spring 642 can reduce a certain inertial impact.

[0045] At the same time, when the steel material F moves backward, it first fits with the fixed chamfer 51, and then pushes the fixed slider 52 downward along the fixed chamfer 51 to squeeze the fixed spring 53, so that the fixed slider 52 completely slides to the lower end of the steel material F. When the fixed slider 52 moves to the lower end of the steel material F, the fixed slider 52 moves downward to squeeze the fixed spring 53, and the lower end of the fixed slider 52 fits with the locking chamfer 551, and gradually pushes the locking slider 555 to the left along the locking chamfer 551 to squeeze the locking spring 554, driving The elastic friction block 5551 at the left end of the locking slider 555 rubs against the fitting rack 73, so that the elastic friction block 5551 limits the fitting rack 73, thereby making it impossible for the fitting spring 72 to reset and push the fitting rack 73 to move, so that the fitting gear 74 cannot rotate, and the telescopic plate 8 cannot extend under the cooperation of the fitting sleeve 75 and the fitting threaded column 76, so as to prevent the telescopic plate 8 from extending and driving the welding plate 2 to move to the right and fit the left end of the steel F when connecting the steel F and the support plate 4, so that the installation steel F can be installed. When welding material F, friction between welding plate 2 and steel material F causes inconvenience in installation, until fixed slider 52 fits with connecting hole G. At this time, fixed slider 52 is reset and inserted into connecting hole G under the action of fixing spring 53. Fixed slider 52 moves up and does not contact locking slider 555. Locking slider 555 moves to the right under the action of locking spring 554, so that elastic friction block 5551 is out of contact with fitting rack 73. At this time, fitting rack 73 is reset and moved under the action of fitting spring 72, driving fitting gear 7 4 rotates forward, the fitting gear 74 drives the fitting sleeve 75 to rotate forward, and cooperates with the fitting threaded column 76 to drive the telescopic plate 8 to move rightward, so that the telescopic plate 8 fits with the welding plate 2, and the welding plate 2 fits with the steel F, so as to achieve the fitting and fixing of the front and back and left and right ends of the steel F, so that when the steel F is installed, there is enough space between the left and right ends for easy installation. After installation, the welding plate 2 fits tightly with the steel F, ensuring that the weld between the steel F and the welding plate 2 is small, which is convenient for subsequent welding between the steel F and the welding plate 2.

[0051] Working principle: After fixing the steel F and the connecting piece 1, the rib plate 3 is installed at the rear of the steel F to increase the longitudinal deformation resistance of the steel F. When the rib plate 3 is installed on the connecting piece 1, the retreat rack 62 on the rib plate 3 is moved forward to cooperate with the fitting gear 74, so that the fitting gear 74 rotates to drive the telescopic plate 8 to move, so that the two ends of the steel F have good shock absorption performance. When the rib plate 3 moves, it also drives the installation block 631 to move, so that the installation block 631 moves to push the elastic friction block 5551 to fix the retreat rack 62, so that the rib plate 3 can strengthen the side strength of the steel F while facilitating the installation and fixation of the rib plate 3 and the connecting piece 1.

[0052] Specifically, after the steel material F is fixed on the connecting member 1, the operator then inserts the rib plate 3 from the rear side of the steel material F, aligns the mounting block 631 with the mounting groove 632, and aligns the retreat rack 62 with the retreat groove 61. Then the operator pushes the rib plate 3 forward to make the rib plate 3 fit with the rear end of the steel material F. During the forward movement of the rib plate 3, the rib plate 3 drives the retreat rack 62 to move forward and first contacts with the fitting gear 74, and then pushes the fitting gear 74 to reverse, so that the telescopic plate 8 moves to the left with the cooperation of the fitting sleeve 75 and the fitting threaded column 76, so that the buffer spring 642 is reset for a distance, so that a certain buffer distance is left between the welding plate 2 connected to the steel material F and the connecting member 1, so that the two ends of the steel material F and the wall E have good shock absorption performance. After the retreat rack 62 drives the fitting gear 74 to rotate for a period of time, the mounting block The front end of 631 fits with the installation chamfer 5661, and with the cooperation of the installation chamfer 5661, the unlocking block 566 is pushed downward to squeeze the unlocking spring 564, and the unlocking block 566 drives the unlocking connecting plate 565 and the stabilizing block 633 to move downward, and the stabilizing block 633 moves downward to fit with the stabilizing push angle 634, and pushes the locking slider 555 to the left along the stabilizing push angle 634. When the locking slider 555 moves to the left, it drives the elastic friction block 5551 to move to the left and fit with the fitting rack 73 until the rib plate 3 and the rear end of the steel F are completely fitted. At this time, the elastic friction block 5551 completely fixes the fitting rack 73, so that the rib plate 3 strengthens the side strength of the steel F, facilitates the installation and fixation of the rib plate 3 and the connecting piece 1, and at the same time, the steel F and the connecting piece 1 have a certain buffering and shock absorbing ability.
