Description

Technical Field

[0001] This utility model relates to the field of construction machinery technology, specifically to a prefabricated building column support device. Background Technology

[0002] Prefabricated buildings refer to buildings where a large amount of on-site work in traditional construction methods is transferred to factories. Building components and accessories are processed and manufactured in factories, transported to the construction site, and assembled on-site using reliable connection methods. Since vertical columns are generally installed as a whole, their stability is not as good as that of concrete-cast columns. Therefore, supports are needed to reinforce the columns.

[0003] For example, the announcement number CN219528522U describes a prefabricated building support column. This device includes a main support column, an adjustable support column at the middle of the bottom end of the main support column, a fixing block fixedly installed at the bottom end of the adjustable support column, and a cross-shaped fixing member fixedly installed at the bottom end of the fixing block. By placing the cross-shaped fixing member on the ground, and then using tools, workers can drill through the four corners of the cross-shaped fixing member into the ground to fix the main support column, thereby achieving convenient installation and disassembly, and a firm fixation.

[0004] During use, the above-mentioned device uses the rotation of the main support column to drive the upper and lower support columns to move up and down via threaded transmission, thereby adjusting the height of the support column. However, since the upper support column lacks a limiting structure, it is easy for the upper support column to rotate along with the main support column when the main support column is rotated, thus preventing the upper support column from extending or retracting. Therefore, we propose a prefabricated building column support device to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a prefabricated building column support device to solve the problem mentioned in the background art that, because the upper support column has no limiting structure, it is easy to rotate the upper support column along with the main support column when rotating, thus causing the upper support column to be unable to extend or retract.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated building column support device, comprising a rotating sleeve;

[0007] Also includes:

[0008] A base plate is located at the bottom of the rotating sleeve. A column is located at the upper center of the base plate and inside the rotating sleeve. The inner wall of the rotating sleeve is provided with internal threads. A screw is provided inside the rotating sleeve and is threadedly connected to the internal threads. The screw extends out of the upper part of the rotating sleeve. A top plate is provided at the upper end of the screw. An anti-slip pad is provided on the upper surface of the top plate. A cross groove is provided inside the screw. A cross rod is provided at the upper end of the column. The cross rod is engaged with the cross groove, and the screw is slidably engaged with the outside of the cross rod through the cross groove.

[0009] Preferably, a bearing is provided between the column and the rotating sleeve.

[0010] Preferably, the outer sides of the rotating sleeve are symmetrically provided with first rotating seats, one end of the first rotating seat is connected to a handle, and the handle swings outside the rotating sleeve through the first rotating seat.

[0011] Preferably, a second rotating seat is provided around the outer periphery of the rotating sleeve. One end of the second rotating seat is connected to a support rod, and the support rod swings outside the rotating sleeve via the second rotating seat. The other end of the support rod is provided with a connecting plate by welding.

[0012] Preferably, the base plate is fixedly connected to the ground by a second bolt.

[0013] Preferably, the connecting plate is connected to the ground by a first bolt.

[0014] Preferably, the outer periphery of the rotating sleeve is provided with limiting blocks, the limiting blocks are located above the corresponding second rotating seat, and the support rod is movably engaged in the slot of the limiting block.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. By setting a column between the rotating sleeve and the base, and setting a bearing on the outside of the column, the rotating sleeve can be rotated. A screw is set inside the rotating sleeve, and a cross groove is set inside the screw. A cross rod is set above the column. The cross rod and the cross groove are movably engaged. When the rotating sleeve drives the screw to rise and fall through the threaded transmission, the engagement of the cross rod and the cross groove can limit the screw, so that the screw will not rotate with the rotating sleeve, thus facilitating the transmission and lifting of the screw.

[0017] 2. By setting threaded holes on the surface of the base plate, bolts are used to fix the base plate to the ground, making the base plate firm. At the same time, a swingable support rod is set around the rotating sleeve. A connecting plate is welded to one end of the support rod and the connecting plate is attached to the ground. The inclined support rod improves the stability of the entire support structure. Threaded holes are set on the surface of the connecting plate. After adjusting the height of the screw, the support rod is flipped down so that the connecting plate is attached to the ground. Bolts are used to fix the connecting plate to the ground, thereby improving the stability of the connecting plate. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] This utility model provides a prefabricated building column support device, which includes a rotating sleeve 1. The main problem addressed by this utility model is that, as mentioned in the background section, the upper support column, lacking a limiting structure, easily rotates along with the main support column, causing the upper support column to be unable to extend or retract.

[0025] For the device provided by this utility model, please refer to Figure 1-4 The following is a detailed introduction.

[0026] The base plate 3 is located at the bottom of the rotating sleeve 1. The base plate 3 is fixedly connected to the ground by the second bolt 18. A column 4 is located in the middle of the upper part of the base plate 3. The column 4 is located inside the rotating sleeve 1. The inner wall of the rotating sleeve 1 is provided with an internal thread 7. A screw 2 is provided inside the rotating sleeve 1. The rotation of the rotating sleeve 1 uses the thread transmission to make the screw 2 rise and fall. The screw 2 is threadedly connected to the internal thread 7. The screw 2 extends out of the upper part of the rotating sleeve 1. A top plate 11 is provided at the upper end of the screw 2. The rise and fall of the screw 2 causes the top plate 11 to be attached to the ceiling for support. An anti-slip pad 12 is provided on the upper surface of the top plate 11 to improve the anti-slip properties of the top plate 11. A cross groove 10 is provided inside the screw 2. A cross rod 6 is provided at the upper end of the column 4. The cross rod 6 is engaged with the cross groove 10. The screw 2 is slidably engaged with the outside of the cross rod 6 through the cross groove 10. A bearing 5 is provided between the column 4 and the rotating sleeve 1.

[0027] To further explain, the outer sides of the rotating sleeve 1 are symmetrically provided with first rotating seats 9. One end of the first rotating seat 9 is connected to a handle 8. The handle 8 swings outside the rotating sleeve 1 through the first rotating seat 9, and the rotating sleeve 1 can be rotated by the handle 8. This can increase the torque to facilitate the rotation of the rotating sleeve 1. When not in use, the handle 8 housing flips over under the action of the first rotating seat 9 and fits against the surface of the rotating sleeve 1 for easy storage.

[0028] To further explain, a second rotating seat 15 is provided around the outer periphery of the rotating sleeve 1. A support rod 14 is connected to one end of the second rotating seat 15, allowing the support rod 14 to swing outside the rotating sleeve 1 via the second rotating seat 15. A connecting plate 16 is welded to the other end of the support rod 14, and the connecting plate 16 is connected to the ground via a first bolt 17. Limit blocks 13 are provided around the outer periphery of the rotating sleeve 1, positioned above the corresponding second rotating seat 15. The support rod 14 is movably engaged with the limit block 13. When not in use, the support rod 14 flips upward and engages with the slot of the limiting block 13, making it easy to store the support rod 14. When the height of the screw 2 is adjusted so that the top plate 11 is against the ceiling, the support rod 14 can be flipped down to attach the connecting plate 16 to the ground. Then, the connecting plate 16 is fixed to the ground with bolts, which can support the entire support structure and improve its stability, and fix the position of the rotating sleeve 1 to prevent the rotating sleeve 1 from rotating and causing the top plate 11 to fall or loosen.
