[0002] At present, in engineering projects, in order to store construction materials, it is inevitable to use factory buildings, and at the end of the construction period, the factory buildings will be demolished. In order to achieve the purpose of recycling the factory buildings, the factory buildings usually adopt steel structures. Specifically, the bottom of the factory building is supported by tubular support columns, and a roof is set on the top. Among them, a chassis is provided at the bottom of the support column, and the chassis is installed on a concrete pier inserted into the ground by bolts. However, the height of the support column is relatively high. Once encountering strong winds, the support column is easy to fall over, so the support column needs to be strengthened.

[0003] Usually, two cross-welded connecting rods are used to reinforce two parallel support columns, so that the two connecting rods and the two support columns form two triangles to improve the stability of the support columns. However, the distance between the two parallel support columns is not always a fixed value. When the distance between the two parallel support columns is adjusted, the two connecting rods cannot adapt because they are welded, and only matching connecting rods can be remade, which reduces the flexibility of use and is not convenient for reuse.

It should be noted that, in the absence of conflict, the embodiments of the present invention and the features described in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] See also Figures 1 to 3, the figure shows a preferred structure of a factory building steel structure connection device provided by an embodiment of the present invention. The factory building steel structure connection device is arranged between two support columns 4 of the factory building, the two support columns 4 are arranged in parallel, and there is a certain distance between the two support plates. As shown in the figure, the factory building steel structure connection device includes: a disk body 1, four telescopic arms 2 and four bases 3. Among them, the disk body 1 can be circular, or a quadrilateral, or other shapes, and this embodiment does not impose any restrictions on this. In this embodiment, the disk body 1 is circular.

[0022] The length of each telescopic arm 2 can be adjusted to meet actual needs. Four telescopic arms 2 are arranged along the circumference of the disc body 1, and the first end of each telescopic arm 2 is connected to the disc body 1, and the second end of each telescopic arm 2 is connected to a base 3. Preferably, the connection between each telescopic arm 2 and the disc body 1 is a detachable connection, and the connection between each telescopic arm 2 and the base 3 is also a detachable connection.

[0023] The base 3 on two adjacent telescopic arms 2 is used to connect with a support column 4, so a triangle is formed between the base 3 of the two adjacent telescopic arms 2 and the disk body 1 to improve the stability between the support column 4 and the disk body 1. The base 3 on the other two telescopic arms 2 is used to connect with another support column 4, so a triangle is also formed between the base 3 of the other two telescopic arms 2 and the disk body 1 to improve the stability between the support column 4 and the disk body 1. The two support columns 4 are arranged in parallel, and there is a preset spacing between the two support columns 4, which can be determined according to actual conditions, and this embodiment does not impose any restrictions on this.

[0024] Each base 3 is adjustably connected to the corresponding support column 4 , so the position of each base 3 on the corresponding support column 4 can be adjusted, that is, the second end of each telescopic arm 2 can be placed at a different position of the corresponding support column 4 .

[0025] It can be seen that in the present embodiment, the base 3 of two adjacent telescopic arms 2 forms a triangle with the disc body 1, and the base 3 of the other two telescopic arms 2 forms another triangle with the disc body 1. The triangular distribution position improves the stability between the two support columns 4 to avoid shaking, and the adjustment of the length of the telescopic arm 2 itself can adapt to the different spacings between the two support columns 4. At the same time, the position of the base 3 on each telescopic arm 2 on the corresponding support column 4 is adjustable, and the position of the base 3 can be further adjusted according to the spacing between the two support columns 4 and the actual situation, so as to adapt to support columns 4 with various different spacings, expand the scope of use, improve the reuse rate, and make it more flexible to use. It solves the problem in the prior art that the connecting rod reinforcement between two parallel support columns of the factory building connected by two cross welds is not convenient for reuse.

[0026] See also Figure 1and Figure 2 In the above embodiment, the first end of each telescopic arm 2 is hingedly connected to the disc body 1. Specifically, the first end of each telescopic arm 2 is connected to the disc body 1 through a pin. In this way, the first end of each telescopic arm 2 can rotate relative to the disc body 1, which is convenient for adjusting the length of the telescopic arm 2 and the position of the base 3 on the telescopic arm 2, thereby improving the flexibility and strength of use.

[0027] See also Figure 1 and Figure 2 In the above embodiment, the second end of each telescopic arm 2 is hingedly connected to the corresponding base 3. Specifically, the second end of each telescopic arm 2 is connected to the corresponding base 3 via a pin. In this way, the second end of each telescopic arm 2 can rotate relative to the corresponding base 3, which is convenient for adjusting the length of the telescopic arm 2 and the position of the base 3 on the telescopic arm 2, thereby improving the flexibility and strength of use.

[0028] See also Figures 1 to 3 In the above embodiments, each telescopic arm 2 may include: a support tube 21, a telescopic plate 22 and a locking mechanism. The interior of the support tube 21 is hollow, and one end of the support tube 21 is open and the other end is closed. The closed end of the support tube 21 is connected to the disc body 1, and preferably, the closed end of the support tube 21 is hingedly connected to the disc body 1.

[0029] In specific implementation, the cross section of the support tube 21 can be quadrilateral, and the support tube 21 can be rectangular. Of course, the support tube 21 can also be other shapes, and this embodiment does not impose any limitation on this.

[0030] The telescopic plate 22 has a preset thickness and a preset length, and the preset depth and the preset length can be determined according to actual conditions, and this embodiment does not impose any restrictions on this. The first end of the telescopic plate 22 is slidably inserted into the support tube 21. Specifically, the telescopic plate 22 is inserted into the support tube 21 from the open end of the support tube 21, and the telescopic plate 22 is slidable in the support tube 21. The second end of the telescopic plate 22 is connected to the corresponding base 3. Preferably, the second end of the telescopic plate 22 is hingedly connected to the corresponding base 3.

[0031] The locking mechanism is provided on the support tube 21, and is used to lock the telescopic plate 22. Specifically, the first end of the telescopic plate 22 is slid toward the inside of the support tube 21 according to the spacing between the two support columns 4, until the length of the telescopic plate 22 placed outside the support tube 21 and the length of the support tube 21 meet the actual requirements, and the locking mechanism locks the telescopic plate 22 to fix the telescopic plate 22 relative to the support tube 21.

[0032] It can be seen that in the present embodiment, each telescopic arm 2 adjusts its own length by partially inserting the telescopic plate 22 into the interior of the support tube 21, and the locking mechanism locks the telescopic plate 22 so that the telescopic plate 22 and the support tube 21 are relatively fixed to ensure that the position of the telescopic plate 22 remains unchanged. The structure is simple and easy to adjust.

[0033] Continue to see Figures 1 to 3 In the above embodiment, the locking mechanism may include: a locking bolt 23. A threaded hole is provided on the outer wall of the support tube 21, and the locking bolt 23 is passed through the threaded hole, and the locking bolt 23 is screwed with the threaded hole, so that the locking bolt 23 and the support tube 21 are relatively fixed. And, after passing through the threaded hole, the locking bolt 23 abuts against the telescopic plate 22, and the telescopic plate 22 is abutted and squeezed by continuously twisting the locking bolt 23, so as to achieve locking of the telescopic plate 22.

[0034] Continue to see Figures 1 to 3 In the above embodiment, a plurality of anti-skid grooves 221 are provided on the side of the telescopic plate 22 facing the threaded hole, and each anti-skid groove 221 has a preset depth and a preset width, which can be determined according to actual conditions, and this embodiment does not impose any restrictions on this. The anti-skid grooves 221 are evenly arranged along the length direction of the telescopic plate 22, and there is a preset distance between any two adjacent anti-skid grooves 221, which can be determined according to actual conditions, and this embodiment does not impose any restrictions on this. Preferably, the anti-skid grooves 221 are arranged at equal intervals.

[0035] The locking bolt 23 is passed through the threaded hole, and is threadedly connected to the threaded hole. After passing through the threaded hole, the locking bolt 23 is placed in any one of the anti-slip grooves 221 , and the locking bolt 23 abuts against the anti-slip groove 221 .

[0036] During specific implementation, the width of each anti-slip groove 221 is greater than the radial distance of the locking bolt 23 , so that the locking bolt 23 is conveniently placed in the anti-slip groove 221 .

[0037] It can be seen that in this embodiment, a plurality of anti-slip grooves 221 are provided on the telescopic plate 22, and the locking bolt 23 is placed in any one of the anti-slip grooves 221 to prevent the locking bolt 23 from sliding, thereby improving the reliability of the locking. Compared with the locking bolt 23 directly abutting against the telescopic plate 22, the locking force is greatly improved.

[0038] Continue to see Figures 1 to 3In the above embodiment, the outer wall of the support tube 21 is provided with a threaded tube 24, and the threaded tube 24 corresponds to the threaded hole. The inner wall of the threaded tube 24 is provided with threads, and the inner diameter of the threaded tube 24 matches the aperture of the threaded hole. The locking bolt 23 is sequentially inserted into the interior of the threaded tube 24 and the threaded hole, and the locking bolt 23 is screwed with the threaded tube 24 and the threaded hole. The locking bolt 23 abuts against the telescopic plate 22, or the locking bolt 23 is placed in any one of the anti-skid grooves 221 of the telescopic plate 22 and abuts against the anti-skid groove 221. In this way, by providing the threaded tube 24 to increase the connection length between the locking bolt 23 and the support tube 21, the locking bolt 23 is more firmly connected to the support tube 21, and the reliability of the locking of the locking bolt 23 is improved.

[0039] Preferably, the threaded tube 24 and the support tube 21 are integrally formed, which improves the overall strength of the support tube 21 and facilitates manufacturing.

[0040] See also Figure 1 and Figure 2 In each of the above embodiments, each base 3 may include: a U-shaped plate 31 and a fastening mechanism. The U-shaped plate 31 includes: two parallel connecting plates and a clamping plate. The clamping plate is clamped between the two connecting plates, and the clamping plate is connected to the two connecting plates and is perpendicular to each other. There is a preset distance between the two connecting plates, and the preset distance can be determined according to actual conditions, and this embodiment does not impose any restrictions on this.

[0041] The U-shaped plate 31 is sleeved on the outside of the corresponding support column 4, and the corresponding support column 4 is disposed inside the U-shaped plate 31 through the opening of the U-shaped plate 31. The distance between the two opposite connecting plates in the U-shaped plate 31 is greater than the radial distance of the corresponding support column 4, so that the U-shaped plate 31 can slide along the support column 4 and can be adapted to different support columns 4, thereby expanding the scope of use.

[0042] The fastening mechanism is provided at any one of the connecting plates of the U-shaped plate 31, and the fastening mechanism is used to fix the U-shaped plate 31 relative to the support column 4, that is, the U-shaped plate 31 can be fixed at any position of the support column 4. The other connecting plate of the U-shaped plate 31 is connected to the second end of the corresponding telescopic arm 2, and preferably, the other connecting plate of the U-shaped plate 31 is hingedly connected to the second end of the corresponding telescopic arm 2.

[0043] It can be seen that in this embodiment, the U-shaped plate 31 is sleeved on the corresponding support column 4, which facilitates the setting of the base and the sliding of the U-shaped plate along the support column 4 to achieve the adjustable position on the support column 4, thereby facilitating the length adjustment of the corresponding telescopic arm 2 to adapt to the spacing between the two support columns 4. In addition, the fastening mechanism can fix the U-shaped plate 31 at any position of the support seat, ensuring the stable fixation of the corresponding telescopic arm 2 and preventing the telescopic arm 2 from moving arbitrarily.

[0044] See also Figure 1 and Figure 2 , the fastening mechanism may include: a fastening bolt 32. Among them, the connecting plate connected to the second end of the corresponding telescopic arm 2 in the U-shaped plate 31 is in contact with the support column 4, then the first side of the connecting plate is connected to the second end of the corresponding telescopic arm 2, and the second side of the connecting plate is in contact with the support column 4, and the first side and the second side of the connecting plate are two opposite sides. Another connecting plate in the U-shaped plate 31 is away from the disk body 1, and the connecting plate is provided with a threaded hole, and the fastening bolt 32 is passed through the threaded hole, and the fastening bolt 32 is screwed with the threaded hole, and the fastening bolt 32 abuts against the support column 4. Specifically, the connecting plate connected to the second end of the corresponding telescopic arm 2 is recorded as the first connecting plate. Since the first connecting plate is in contact with the support column 4, the fastening bolt 32 abuts against the support column 4, so that the support column 4 is in close contact with the first connecting plate, and the squeezing force between the fastening bolt 32 and the first connecting plate is used to lock the U-shaped plate, thereby ensuring the relative fixation of the U-shaped plate 31 and the support column 4.

[0045] In a specific implementation, there may be at least two threaded holes, and the threaded holes are evenly distributed on the connecting plate. The number of the fastening bolts 32 is the same as the number of the threaded holes and corresponds one to one.

[0046] See also Figure 1 and Figure 2 , the fastening mechanism may also include: a boost block 33. Among them, since the distance between the two parallel connecting plates in the U-shaped plate 31 is greater than the radial distance of the support column 4, the boost block 33 is placed between the connecting plate with threaded holes in the U-shaped plate 31 and the support column 4. In addition, the boost block 33 is rotatably connected with the fastening bolt 32. Specifically, the fastening bolt 32 is rotatably connected with the boost block 33 after the threaded hole is penetrated, and the fastening bolt 32 abuts against the support column 4 through the boost block 33. The fastening bolt 32 is not moved and is twisted, and its force is applied to the boost block 33, and then the force is transmitted to the support column 4 through the boost block 33, so that the support column 4 is abutted and squeezed to achieve relative fixation of the U-shaped plate 31 and the support column 4. In addition, the boost block 33 is in contact with the support tube 21, which greatly increases the contact area with the support column 4, increases the friction during fastening, and improves the firmness. Furthermore, the boost block 33 is rotatably connected to the fastening bolt 32, so the rotation of the fastening bolt 32 will not drive the rotation of the boost block 33, thereby preventing the fastening bolt 32 from directly abutting against the support column 4 and wearing the support column 4 due to its rotation, thereby extending the service life of the support column 4 and facilitating the rotation of the fastening bolt 32.

[0047] In specific implementation, a groove is provided on the side of the booster block 33 facing the fastening bolt 32, the shape of the groove matches the shape of the fastening bolt 32, and the diameter of the groove is slightly larger than the outer diameter of the fastening bolt 32. The fastening bolt 32 is placed in the groove after passing through the threaded hole, and the groove does not affect the rotation of the fastening bolt 32, but the booster block 33 does not rotate with the fastening bolt 32, so that the booster block 33 and the fastening bolt 32 are rotatably connected.

[0048] In a specific implementation, there are at least two boosting blocks 33 , the number of the boosting blocks 33 is the same as the number of the fastening bolts 32 and corresponds one to one, and the position of each boosting block 33 corresponds one to one to the position of each fastening bolt 32 .

[0049] Combination Figures 1 to 3 The installation process of the steel structure connection device of the factory building is introduced: the two support columns 4 have been installed in advance, and the distance between the two support columns 4 has been determined. First, the disc body 1 is hingedly connected to the support tubes 21 in the four telescopic arms 2, and the telescopic plate 22 in each telescopic arm 2 is hingedly connected to a base 3. Loosen the locking bolts 23 and adjust the position of the telescopic plate 22 to adapt to the distance between the two support columns 4. Then, the open end of the U-shaped plate 31 of each base 3 is sleeved on the outside of the support column 4, and the U-shaped plate 31 is slid along the height direction of the support column 4, and the position of the telescopic plate 22 is adjusted at the same time until the distance between the two support columns 4 is met, and each fastening bolt 32 is turned in turn to abut against the support column 4 through the booster block 33 to fix each base 3 relative to the corresponding support column 4. At this time, each support column 4 forms a stable triangle with the two telescopic arms 2 connected thereto to improve stability and avoid shaking. Then, the position of the telescopic plate 22 is fine-tuned to adapt to the distance between the two support columns 4. After the position of the telescopic plate 22 is adjusted, the locking bolt 23 abuts against the anti-slip groove 221 on the telescopic plate 22 to lock the position of the telescopic plate 22, thereby determining the length of the telescopic arm 2 and completing the installation of the factory steel structure connection device between the two support columns 4.

[0050] To sum up, in this embodiment, the base 3 of two adjacent telescopic arms 2 forms a triangle with the disc body 1, and the base 3 of the other two telescopic arms 2 forms another triangle with the disc body 1. The triangular distribution position improves the stability between the two support columns 4 to avoid shaking, and the adjustment of the length of the telescopic arm 2 itself can adapt to the different distances between the two support columns 4. The position of the base 3 is adjusted according to the distance between the two support columns 4 and the actual situation, so as to adapt to support columns 4 with various different distances, expand the scope of use, improve the reuse rate, and be more flexible in use.

[0051] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
