Description

Technical Field

[0001] This utility model relates to the field of building engineering, and in particular to a detachable building support device. Background Technology

[0002] In building construction, especially in the construction of high-rise buildings or large structures, it is often necessary to build a large number of temporary support systems to ensure the stability and safety of the structure.

[0003] Traditional support methods often use steel pipe scaffolding connected with couplers. Although this system is widely used, it has many shortcomings. This design concept pursues the absolute firmness and no displacement of the connection. Since the temporary support system is usually exposed to the external environment, when the temporary support device faces extreme dynamic environments such as wind load, earthquake, impact or temperature change, the external load will force the overall structure to deform. At this point, the connection of the device will generate a large amount of stress due to external loads. At the same time, the stress will be transmitted directly and cannot be released, and will be highly concentrated at the connection point, which is a "mechanical bottleneck". Since the deformation is prevented by rigid constraints, the huge energy cannot be dissipated and can only accumulate continuously inside the connection area. This causes the local stress value in the area to far exceed the average yield strength of the material. This will accelerate the fatigue process of the material. Under cyclic loading, tiny cracks will start and propagate from stress peak points, such as weld edges and around bolt holes. Ultimately, the connection will experience fatigue fracture at a stress level far below the design load, which greatly shortens the safe service life of the structure. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a detachable building support device. This addresses the problem in the aforementioned technical solutions where, under cyclic loading, minute cracks can initiate and propagate from stress peak points, such as weld edges and around bolt holes, ultimately leading to fatigue fracture at the connection points under stress levels far below the design load, significantly shortening the structural service life. A detachable building support device includes a base plate, a column tube fixedly connected to the top of the base plate, a slot formed on the outer side wall of the column tube, a fixing plate fixedly connected to the inner side wall of the column tube, a telescopic rod fixedly connected to the bottom of the fixing plate, a locking block fixedly connected to the fixed end of the telescopic rod, an adjusting rod fixedly connected to the top of the locking block, a tension spring fixedly connected to the bottom of the fixing plate, the end of the tension spring away from the fixing plate being fixedly connected to the top of the locking block, a locking post engaging the column tube through the slot, a pull rod fixedly connected to the side of the locking post away from the column tube, and the bottom outer side wall of the locking block fitting into the top outer side wall of the locking post.

[0005] A protrusion is fixedly connected to the outer wall of the column tube. A spherical joint is fixedly connected to the outer wall of the protrusion away from the column tube. A positioning bolt is rotatably connected through the outer wall of the protrusion. A crossbeam is rotatably connected to the protrusion through the positioning bolt. The end of the spherical joint away from the protrusion is ball-jointed with the end of the crossbeam near the spherical joint. By setting the protrusion, spherical joint, positioning bolt, and crossbeam, it is convenient for the operator to adjust the angle of the crossbeam.

[0006] The outer wall of the crossbeam is provided with a positioning groove to reduce its weight and provide flexible fixing points. The positioning groove makes it easy for installers to make fine adjustments before finally tightening the bolts, which greatly reduces the installation difficulty and improves the construction efficiency.

[0007] A connecting plate is fixedly connected to the end of the column tube away from the base plate. A clamp is snapped into the outer wall of the connecting plate. An anti-slip bushing is fixedly connected to the inner wall of the clamp. A connecting block is fixedly connected to the outer wall of the clamp. A threaded rod is slidably connected to the inner wall of the connecting block. A washer is provided at the end of the threaded rod away from the connecting block. By setting up the clamp, anti-slip bushing, connecting block, threaded rod, and washer, the anti-slip bushing can improve the friction between the clamp and the column tube, thereby preventing displacement when the two column tubes are connected. At the same time, it is convenient to lock rods of different diameters.

[0008] A cable conduit is fixedly connected to the top of the base plate. The cable conduit is located inside the column pipe. By setting up the cable conduit, it is convenient for operators to lay cable lines.

[0009] The top of the base plate has a through-hole for positioning, and the outer side wall of the base plate is fixedly connected with an ear block. By setting the positioning hole and the ear block, the positioning hole and the positioning pin cooperate to achieve multi-directional precise alignment, and the ear block facilitates mechanical hoisting operation.

[0010] The bottom of the base plate is provided with anti-slip serrations to improve the grip of the base plate. By providing anti-slip serrations, the stability of the base plate in different geological environments can be improved.

[0011] In summary: By using a combination of column tubes, slots, fixing plates, telescopic rods, tension springs, locking blocks, adjusting rods, tie rods, and locking posts, rigid connections between tie rods and column tubes are avoided. This significantly reduces stress concentration at the connection points between tie rods and column tubes in extreme environments, thereby reducing the destructive impact of peak loads on the main structure.

[0012] The use of column tubes, protrusions, ball joints, positioning bolts, and crossbeams allows operators to easily adjust the angle of the crossbeams according to the operating environment, thereby improving the environmental adaptability of the device. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0016] like Figure 1 , Figure 2 and Figure 3As shown, this utility model provides a technical solution: a detachable building support device, comprising a base plate 1, with a column tube 2 fixedly connected to the top of the base plate 1. The column tube 2 has an octagonal cross-section to enhance torsional rigidity. The column tube 2 is formed by extrusion of aluminum alloy profiles. Eight slots 3 are provided on the outer wall of the column tube 2, located on the eight outer walls of the column tube 2, and arranged in a linear array along the outer wall of the column tube 2. Taking one slot 3 as an example, the slot 3 is divided into two parts, with the dimension of the end of the slot 3 furthest from the base plate 1 being larger than the dimension of the end of the slot 3 closest to the base plate 1. Fixing plates 4 are fixedly connected to the inner wall of the column tube 2, with the number and position of the fixing plates 4 corresponding to the number and position of the slots 3. Here, one fixing plate is used as an example. Taking plate 4 as an example, a telescopic rod 5 is fixedly connected to the bottom of the fixed plate 4, a locking block 7 is fixedly connected to the fixed end of the telescopic rod 5, an adjusting rod 8 is fixedly connected to the top of the locking block 7, the end of the adjusting rod 8 away from the locking block 7 is located outside the column tube 2, a slot is opened through the outer wall of the locking block 7, a tension spring 6 is fixedly connected to the bottom of the fixed plate 4, the end of the tension spring 6 away from the fixed plate 4 is fixedly connected to the top of the locking block 7, the column tube 2 is clamped with a locking post 10 through the slot 3, a pull rod 9 is fixedly connected to the side of the locking post 10 away from the column tube 2, the slot opened on the bottom outer wall of the locking block 7 matches the top outer wall of the locking post 10, and the outer wall of the locking post 10 matches the inner wall of the slot 3 near the base plate 1, so that the column tube 2 can limit the locking post 10 through the slot 3.

[0017] like Figure 2 , Figure 4 As shown, a protrusion 13 is fixedly connected to the outer wall of the column tube 2. A ball joint 14 is fixedly connected to the outer wall of the protrusion 13 away from the column tube 2. A positioning bolt 15 is rotatably connected through the outer wall of the protrusion 13. A crossbeam 16 is rotatably connected to the protrusion 13 through the positioning bolt 15. The end of the ball joint 14 away from the protrusion 13 is ball-jointed with the end of the crossbeam 16 near the ball joint 14, so that during use, the operator can use the positioning bolt 15 as the axis to finely adjust the angle between the crossbeam 16 and the column tube 2.

[0018] like Figure 1 and Figure 4 As shown, a positioning groove 17 is provided through the outer wall of the crossbeam 16. The positioning groove 17 is designed in a waist shape to reduce its own weight and provide flexible fixing points. The positioning groove 17 is located on the outer wall of the crossbeam 16, providing adjustment margin and allowing installers to make fine adjustments before finally tightening the bolts. This greatly reduces the difficulty of installation and improves construction efficiency. At the same time, the two ends of the positioning groove 17 are usually smooth arc transitions. This shape can significantly reduce stress concentration and prevent cracks from starting and spreading from the hole corner, thereby improving the fatigue life of the component.

[0019] like Figure 4 and Figure 5 As shown, a connecting plate 11 is fixedly connected to the end of the column tube 2 away from the base plate 1. The radial dimension of the connecting plate 11 is larger than the radial dimension of the column tube 2. A clamp 18 is snapped onto the outer wall of the connecting plate 11. An anti-slip bushing 19 is fixedly connected to the inner wall of the clamp 18. The anti-slip bushing 19 is made of wear-resistant polyurethane, which increases the friction between the clamp 18 and the column tube 2, thereby preventing the clamp 18 from detaching when snapping onto the column tube 2. A connecting block 20 is fixedly connected to the outer wall of the clamp 18. A threaded rod 21 is slidably connected to the inner wall of the connecting block 20. A gasket 22 is provided at the end of the threaded rod 21 away from the connecting block 20.

[0020] like Figure 1 , Figure 4 and Figure 6 As shown, a cable conduit 12 is fixedly connected to the top of the base plate 1. The cable conduit 12 is located inside the column tube 2. The radial cross section of the column tube 2 is also octagonal to improve the overall rigidity of the device. At the same time, the operator can install the cable line through the cable conduit 12 to avoid the cable being directly exposed to the outside, thereby improving the service life of the cable.

[0021] like Figure 1 and Figure 6 As shown, a positioning hole 23 is provided through the top of the base plate 1. There are four positioning holes 23, which are located at the four corners of the base plate 1. During use, the operator can adjust the placement angle of the base plate 1 by cooperating with the positioning pin and the positioning hole 23. The outer wall of the base plate 1 is fixedly connected with a lug 24. There are four lugs 24, which are arranged in pairs and located on both sides of the base plate 1 to facilitate the operator to hoist the base plate 1.

[0022] like Figure 1 and Figure 6 As shown, the bottom of the base plate 1 is provided with anti-slip teeth 25. The anti-slip teeth 25 are laser-cut, and there are several anti-slip teeth 25 arranged in a matrix to ensure effective grip under different geological conditions.

[0023] Working principle: like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, in use, the operator lifts the locking block 7 using the adjusting rod 8. During this movement, the locking block 7 compresses the tension spring 6. As the tension spring 6 compresses, its own elasticity gradually accumulates, and the telescopic rod 5 retracts synchronously with the movement of the locking block 7, causing the locking block 7 to move away from the base plate 1. The operator then inserts the locking post 10 into the column tube 2 through the slot 3 at the end away from the base plate 1, and simultaneously moves the locking post 10 towards the base plate 1. Because the two ends of the slot 3 have different dimensions, the locking post 10 moves towards the base plate 1. When the slot 3 is at its lowest point, the inner wall of the column tube 2 engages with the end of the locking post 10 away from the pull rod 9, preventing the pull rod 9 from disengaging from the column tube 2 during use. At the same time, the adjusting rod 8 is released, and under the elastic force of the tension spring 6, the bottom outer wall of the locking block 7 fits against the top outer wall of the locking post 10. Under the elastic force of the tension spring 6, the locking block 7 restricts the position of the locking post 10, preventing the angle of the locking post 10 from changing significantly during use. This prevents the position of the locking post 10 from moving from the bottom of the slot 3 to the top of the slot 3, and thus prevents the locking post 10 from disengaging from the top of the slot 3 from the column tube 2. The tie rod 9 and the locking post 10, together with the slot 3 and the locking block 7, form an "elastic hinge" between the tie rod 9 and the column tube 2, which allows for slight amplitude displacement and rotation. When the device is subjected to load, vibration or thermal deformation, the elasticity of the tension spring 6 can absorb and dissipate some energy, and allow slight adaptive adjustments at the connection between the tie rod 9, the locking post 10 and the column tube 2. This effectively disperses the concentrated stress to a larger contact area, avoids the stress from rising sharply at rigid nodes, and improves the structure's seismic resistance, impact resistance, fatigue life and overall adaptability.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
