Description

Technical Field

[0001] The utility model relates to the technical field of building engineering facilities, in particular to a box-type column assembly device. Background Art

[0002] The box column is named because of its shape like a large iron box. It is generally used as a beam or column on a steel structure. Box columns are widely used in high-rise buildings, large-span structures, subway stations, airports, bridges and other projects. Its main function is to bear vertical and horizontal loads. The box column not only has a large load-bearing capacity, but also can quickly transfer the load in a distributed manner, making the entire structure more solid and stable. In addition, due to the superior performance of the box column, it can reduce the deadweight of the structure, reduce the cost of the structure, and improve the safety and reliability of the building.

[0003] Box columns often need to be installed in combination. However, the current combination installation of box columns is usually welded on-site according to the combination requirements of various scenarios, which is time-consuming and labor-intensive, lacks combination flexibility, and is not conducive to reuse after disassembly. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a box-type column combination device in view of the above-mentioned technical deficiencies, which can adapt to the requirements of various combination scenes, has high flexibility in combination installation, saves time and effort, and is easy to reuse.

[0005] The technical solution adopted by the utility model is: to provide a box-type column assembly device, including support frames fixed to the two ends of the inner wall of the box-type column along the circumferential direction; the box-type column is arranged vertically; the support frames at the upper and lower ends of the box-type column are respectively provided with expansion connection components; the upper and lower ends of the box-type column are respectively uniformly provided with a plurality of card slots along the circumferential direction;

[0006] The extended connection assembly includes a mounting rod arranged vertically; a connecting shaft is coaxially fixed to the upper end of the mounting rod; an extension rod is rotatably connected outside the connecting shaft; the extension rod is arranged in the horizontal direction; the extension rod and the card slot are plugged in and correspond to each other along the vertical direction; a plurality of connection holes are provided on the extension rod; a card block is fixed on the lower side of the extension rod; an arc-shaped limiting groove is circumferentially provided at the lower part of the mounting rod; the limiting groove corresponds to the support frame; the connecting shaft is rotated to enable the limiting groove and the support frame to be sleeved or separated; an end cap is sleeved and fixed on the upper end of the connecting shaft; a positioning stud is vertically inserted through one side of the end cap; the positioning stud passes through the extension rod and is connected to the positioning screw hole provided at the upper end of the mounting rod; when the positioning stud is connected to the positioning screw hole and the card block is blocked on the outer wall of the box-type column, the limiting groove is correspondingly sleeved on the outside of the support frame, and the inner end of the support frame blocks the limiting groove.

[0007] To further optimize the technical solution, a box-type column assembly device has closed baffles fixed to the inner walls of both ends of the box-type column respectively; the closed baffles are closer to the middle of the box-type column than the support frame on the same side.

[0008] To further optimize the technical solution, extension screws are vertically fixed on the sides of two closed baffles of a box-type column assembly device that are away from each other.

[0009] To further optimize the technical solution, the depth of the slot of a box-type column assembly device is greater than the thickness of the extension rod.

[0010] The beneficial effects of the utility model are:

[0011] 1. The extension rod can extend outward from the end of the box-shaped column in the horizontal direction. Combined with the multiple connection holes on the extension rod, it can be easily connected with other box-shaped columns or other building structures. The end of the box-shaped column is evenly provided with multiple slots along the circumference, so that the extension rod can be extended in a more flexible direction, improving the adaptability during combined installation.

[0012] 2. By rotating the connecting shaft and the extension rod, the direction of the installation rod can be adjusted, so that the limiting groove can be switched between the state of being connected or separated from the support frame; when the positioning stud is connected to the positioning screw hole and the block is blocked on the outer wall of the box-type column, the limiting groove is correspondingly connected to the outside of the support frame, and the inner end of the support frame blocks the limiting groove. Through this arrangement, the extension rod and the box-type column can be firmly locked, ensuring the firmness after the combined installation.

[0013] 3. By driving the installation rod to rotate through the connecting shaft, the limiting groove and the support frame can be separated. Combined with the setting of vertical plug-in of the extension rod and the card slot, the entire expansion connection component can be easily removed, which is convenient for changing the installation position of the expansion connection component, further improving the flexibility during installation.

DETAILED DESCRIPTION

[0019] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] like Figure 1-2 As shown, a box-type column assembly device comprises support frames 2 fixed to both ends of the inner wall of a box-type column 1 in a circumferential direction; the box-type column 1 is arranged vertically; the support frames 2 at the upper and lower ends of the box-type column 1 are respectively provided with expansion connection components; the upper and lower ends of the box-type column 1 are respectively uniformly provided with a plurality of card slots 3 in a circumferential direction;

[0021] like Figure 2-3 As shown, the extended connection assembly includes a mounting rod 4 arranged vertically; a connecting shaft 5 is coaxially fixed on the upper end of the mounting rod 4; an extension rod 6 is rotatably connected to the outside of the connecting shaft 5; the extension rod 6 is arranged in the horizontal direction; the extension rod 6 is plugged in and corresponds to the card slot 3 along the vertical direction; a plurality of connecting holes 7 are provided on the extension rod 6; a card block 8 is fixed on the lower side of the extension rod 6; an arc-shaped limiting groove 9 is circumferentially provided at the lower part of the mounting rod 4; the limiting groove 9 corresponds to the support frame 2; the rotation of the connecting shaft 5 is used to make the limiting groove 9 and the support frame 2 sleeve or separate; an end cap 10 is sleeved and fixed on the upper end of the connecting shaft 5; a positioning stud 11 is vertically inserted through one side of the end cap 10; the positioning stud 11 penetrates the extension rod 6 and is correspondingly connected to the positioning screw hole 12 provided on the upper end of the mounting rod 4; when the positioning stud 11 is connected to the positioning screw hole 12 and the card block 8 is blocked on the outer wall of the box-type column 1, the limiting groove 9 is correspondingly sleeved on the outside of the support frame 2, and the inner end of the support frame 2 blocks the limiting groove 9.

[0022] When it is necessary to combine and install with other box-type columns 1 or building structures, in the present technical solution, the corresponding number and position of extended connection components can be arranged on the box-type column 1 as needed. After being firmly connected to the box-type column 1 through the extended connection component, it is then connected to other facilities through the extended connection component, so that the box-type column 1 can be conveniently combined and installed with other facilities.

[0023] Specifically, Figure 2 As shown, the extension rod 6 is limited by the card slot 3 at the corresponding position, and then the installation rod 4 and the extension rod 6 are locked by connecting the positioning stud 11 and the positioning screw hole 12, so that when the card block 8 is blocked on the outer wall of the box-type column 1, the limiting groove 9 is correspondingly sleeved on the outside of the support frame 2, and the inner end of the support frame 2 blocks the limiting groove 9. At this time, the entire extended connection assembly is locked on the box-type column 1, ensuring stability during combined installation.

[0024] like Figure 4 As shown, when the extended connection assembly needs to be installed or removed, the connection between the positioning stud 11 and the positioning screw hole 12 is released, and the mounting rod 4 is driven to rotate by rotating the end cap 10, so that the limiting groove 9 and the support frame 2 can be separated. At this time, the extended connection assembly can be easily removed from the box-type column 1, further improving the flexibility of the device when used in combination.

[0025] like Figure 4 As shown, the inner walls of both ends of the box-shaped column 1 are respectively fixed with closed baffles 13; the closed baffles 13 are closer to the middle of the box-shaped column 1 than the support frame 2 on the same side. The closed baffles 13 play a blocking role for the extended connection assembly, preventing the extended connection assembly from falling deep inside the box-shaped column 1 during installation or removal.

[0026] like Figure 4 As shown, the two closed baffles 13 are respectively vertically fixed with extension screws 14 on the sides away from each other. The expansion performance of connecting the ends of the box-shaped column 1 with other facilities can be further increased by connecting the screws.

[0027] like Figure 2 As shown, the depth of the slot 3 is greater than the thickness of the extension rod 6. The extension rod 6 does not exceed the two ends of the box-shaped column 1 in the height direction, ensuring that the ends of the box-shaped column 1 can directly contact with the remaining equipment during assembly and connection, thereby improving the connection firmness.
