Description

Technical Field

[0001] This utility model relates to a steel structure connection device, and more particularly to a modular steel structure connection device applied in the field of building connectors. Background Technology

[0002] When installing steel structure workshops, steel structure connectors are usually used, including high-strength bolt connections, welded connections, and riveted connections. In addition, there are some special steel structure connectors, such as adjustable steel structure connectors and snap-fit ​​connectors, which can be selectively used according to the specific construction conditions.

[0003] Chinese utility model patent CN213418078U discloses a steel structure connection structure that facilitates the rapid installation of beams and columns. It utilizes the inclination angle of trapezoidal sliding plates to quickly and accurately locate the connection position even when the beam is swaying during installation. At the same time, the beam is fixed and limited by a threaded fixing module. The operation is simple and quick, reducing manpower and material resources, ensuring structural strength while accelerating the project progress.

[0004] Existing steel structure connectors utilize the assembly and disassembly of bolts to achieve rapid assembly. However, in actual operation, this involves the assembly and disassembly of a large number of bolts, making the process cumbersome and inconvenient. Summary of the Invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by this utility model is how to realize the assembly and disassembly of the modular steel structure connection device with multiple steel structures, thereby improving the assembly and disassembly efficiency.

[0006] To address the aforementioned problems, this utility model provides a modular steel structure connection device, comprising a column, two mounting blocks fixedly connected to the surface of the column, a bidirectional screw rod rotatably mounted through the surfaces of the two mounting blocks that are close to each other, a movable ring threaded onto the surface of the bidirectional screw rod, a short rod fixed to the bottom of the movable ring, a crossbeam perpendicular to the column connected to one side surface of the column via a constraint member, the constraint member comprising two split frames, the tops of the two split frames being fixedly connected to the bottoms of the two short rods respectively, both ends of the bidirectional screw rod extending to the outside of the mounting blocks, a steel wire rope wound around the surface of the bidirectional screw rod located on the outside of the mounting blocks, a pulley component movably connected to the surface of the column via a hinged ball, a hanging ring fixed to the top of each of the two split frames, the steel wire rope wound around the surface of the pulley component and its tail end connected to the hanging ring.

[0007] In the above-mentioned modular steel structure connection device, by using the cooperation of bidirectional screws, split frames and steel cables, the crossbeams can be connected when the split frames are close to the splicing, and the steel cables can be used for traction to reduce the gravity load of the bidirectional screws.

[0008] As a further improvement of this application, the surface of the bidirectional screw is provided with two threaded regions of equal length, and the length of each threaded region is greater than the length of each split frame. A handle is inserted into the end of the bidirectional screw located outside the mounting block.

[0009] As a further improvement of this application, when the bidirectional screw rotates in the forward direction, the two moving rings on the surface move closer to each other and the wire rope is wound up; when the bidirectional screw rotates in the reverse direction, the two moving rings on the surface move further apart and the wire rope is released.

[0010] As a further improvement of this application, a plurality of rolling balls are movably installed on the bottom wall of each split frame, and a plug-in block is provided on the surface of one split frame near the bottom of another split frame, and a plug-in groove matching the plug-in block is provided on the surface of the other split frame.

[0011] As another improvement of this application, each plug-in block has a compression spring installed on its inner wall, the tail end of the compression spring is connected to a compression plate, and there is a vertical gap between the bottom end of the compression plate and the surface of the ball.

[0012] As a further improvement of this application, the connection position between the short rod and the split frame is close to the middle position of the constraint member, and the maximum distance of the split frame away from the movement is not less than the cross-sectional width of the beam.

[0013] In summary, this application utilizes the combination of a bidirectional screw, a splitting frame, and a steel wire cable to connect the crossbeam when the splitting frame is close to the splicing point. The steel wire cable is used for traction to reduce the gravitational load on the bidirectional screw. When the splitting frame is far away, the crossbeam loses its supporting function and can fall independently. This enables rapid separation of the column and crossbeam. Compared with the bolted operation of the prior art, it can reduce the use of bolts and improve the efficiency of connection by simplifying the operation steps. Attached Figure Description

[0023] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0024] First implementation method:

[0025] Figure 1-2 and Figure 4 A modular steel structure connection device is shown, including a column 1. Two mounting blocks are fixedly connected to the surface of the column 1. A bidirectional screw 5 is rotatably mounted through the surfaces of the two mounting blocks that are close to each other. A movable ring is threaded onto the surface of the bidirectional screw 5. A short rod 6 is fixed to the bottom of the movable ring. A crossbeam 2 arranged perpendicular to the column 1 is connected to one side surface of the column 1 through a constraint member 4. The constraint member 4 includes two split frames 41, and the tops of the two split frames 41 are fixedly connected to the bottoms of the two short rods 6 respectively. Both ends of the bidirectional screw 5 extend to the outside of the mounting blocks. A steel wire cable 3 is wound around the surface of the bidirectional screw 5 on the outside of the mounting blocks. A pulley member 7 is movably connected to the surface of the column 1 through a hinge ball. A hanging ring is fixed to the top of each of the two split frames 41. The steel wire cable 3 is wound around the surface of the pulley member 7 and its tail end is connected to the hanging ring.

[0026] The surface of the bidirectional screw 5 has two threaded areas of equal length, and the length of each threaded area is greater than the length of each split frame 41. The end of the bidirectional screw 5 located outside the mounting block is connected to a handle (the handle is prior art and is not shown in the figure).

[0027] Figure 5-6 As shown, when the bidirectional screw 5 rotates in the forward direction, the two moving rings on the surface move closer to each other and the wire rope 3 is wound up; when the bidirectional screw 5 rotates in the reverse direction, the two moving rings on the surface move further apart and the wire rope 3 is released.

[0028] The connection position between the short rod 6 and the split frame 41 is close to the middle position of the constraint member 4, and the maximum distance of the split frame 41 away from the movement is not less than the cross-sectional width of the beam 2.

[0029] Specifically, when installing the crossbeam 2 and the column 1, the crossbeam 2 needs to be hoisted to the corresponding installation height so that the two split frames 41 are located on both sides of the crossbeam 2. Then, the bidirectional screw 5 is rotated forward, which can drive the moving ring to move closer to each other, thereby driving the split frames 41 to move closer to each other, forming a covering treatment for the crossbeam 2. As the bidirectional screw 5 rotates forward, the steel wire cable 3 will be gradually tightened. Because the length of the steel wire cable 3 used to pull the split frames 41 in the opposite state is greater than the length of the steel wire cable 3 used to pull the split frames 41 in the spliced ​​state, after splicing, in order to ensure that the steel wire cable 3 is still in a taut and pulled state, the steel wire cable 3 needs to be wound up.

[0030] When it is necessary to separate the crossbeam 2 and the column 1 in the future, the two separation frames 41 can be moved away by rotating the bidirectional screw 5 in the opposite direction. At this time, the distance exposed at the bottom of the two separation frames 41 is greater than the cross-section of the crossbeam 2, so that the crossbeam 2 can fall off on its own and achieve rapid separation.

[0031] In this embodiment, since the length of the threaded area is greater than the length of the split frame 41, when the distance between the two split frames 41 is sufficient for the crossbeam 2 to fall after the split frame 41 moves, the moving ring has not moved to the end of the threaded area. Therefore, it is necessary to rotate in the opposite direction to make the split frame 41 approach and drive the wire rope 3 to be released, so that the wire rope 3 can play a pulling role when the split frame 41 approaches.

[0032] After the column 1 and the crossbeam 2 are connected, the steel wire cable 3 can pull the constraint member 4 covering the crossbeam 2 to reduce the gravity load of the bidirectional screw 5.

[0033] Compared with the use of a large number of bolts in existing technologies, the rapid connection between steel structures can be achieved by moving the split frames 41 closer or further apart, reducing the use of bolts and improving assembly and disassembly efficiency.

[0034] Figure 3 As shown, a plurality of rolling balls 42 are movably mounted on the bottom wall of each split frame 41. One split frame 41 is provided with a plug-in block 43 near the bottom of the surface of another split frame 41, and the surface of the other split frame 41 is provided with a plug-in groove that matches the plug-in block 43.

[0035] Specifically, the use of the ball 42 can change the contact friction between the split frame 41 and the bottom of the crossbeam 2 into rolling friction when they move away from or close to each other, thus reducing the friction effect. In addition, the cooperation between the plug block 43 and the plug slot can enhance the connection stability between the two when the split frame 41 is spliced.

[0036] When the split frames 41 are far apart, even if the projection of some plug-in blocks 43 in the vertical direction overlaps with the crossbeam 2, the overlapping area is small and will not interfere with the autonomous descent of the crossbeam 2.

[0037] Second implementation method:

[0038] Figure 7 It is shown that a compression spring 8 is installed on the inner wall of each plug block 43, and the tail end of the compression spring 8 is connected to a compression plate 9, and there is a vertical gap between the bottom end of the compression plate 9 and the surface of the ball 42.

[0039] Unlike the first embodiment, in this embodiment, the crossbeam 2 with different cross-sectional width values ​​can be constrained by the compression plate 9 and the compression spring 8, thereby increasing the applicability of the constraint member 4.

[0040] In summary, by utilizing the combination of the bidirectional screw 5, the splitting frame 41, and the steel wire cable 3, the crossbeam 2 can be connected when the splitting frame 41 is close to the splicing point, and the steel wire cable 3 can be used to pull and reduce the gravity load of the bidirectional screw 5. When the splitting frame 41 is far away, the crossbeam 2 loses its supporting effect and can fall independently. This enables the rapid separation of the column 1 and the crossbeam 2. Compared with the bolting operation of the existing technology, it can reduce the use of bolts and improve the operation efficiency during connection by simplifying the operation steps.

[0041] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
