Description

Technical Field

[0001] This application relates to the technical field of support devices for profiled steel sheets in steel structures, and in particular to a downward deflection support device for profiled steel sheets in steel structures. Background Technology

[0002] In modern building construction, steel structure technology has been widely applied. Among these, profiled steel sheets, as the supporting structure for concrete floors, play a crucial role in improving construction efficiency and ensuring project quality. With the development of the construction industry, the requirements for construction speed and cost control are becoming increasingly stringent. Traditional construction methods are gradually revealing many shortcomings, necessitating more efficient and economical solutions to meet the growing market demand. Especially in high-rise building construction, ensuring the stability of profiled steel sheets during concrete pouring and preventing sagging deformation has become a key technical challenge.

[0003] Currently, temporary support using timber is commonly used to address the deflection problem of profiled steel sheets. In practice, construction workers place timber under the profiled steel sheets and adjust their position and number to achieve effective support. Alternatively, fixed metal supports are used, which are welded or bolted to the floor slab to provide support for the profiled steel sheets. However, these methods each have limitations and are difficult to fully adapt to the complex and ever-changing actual construction environment.

[0004] The main drawbacks of the aforementioned traditional support methods are inconvenient construction and significant resource waste. On the one hand, timber support requires extensive manual labor, and the installation and dismantling process is cumbersome, especially when adjusting the support length quickly for different floor heights, leading to low construction efficiency. On the other hand, timber is a disposable material that cannot be reused, increasing the overall project cost. While fixed metal supports can be used multiple times, their rigid structure makes them difficult to adjust flexibly according to actual needs, resulting in poor applicability. To address the resource waste caused by traditional support methods, this application provides a steel structure profiled steel sheet downward deflection support device. Utility Model Content

[0005] To address the resource waste caused by traditional support methods, this application provides a deflection support device for profiled steel sheets in steel structures.

[0006] This application provides a deflection support device for profiled steel sheets in steel structures, which adopts the following technical solution:

[0007] A steel structure profiled steel sheet downward deflection support device includes a main support rod and sleeve portions disposed at both ends of the main support rod. A folding frame is fixedly connected to one end of each sleeve portion away from the main support rod. The sleeve portion is slidably disposed along the length direction of the main support rod and forms a detachable fixed connection with it. A positioning pressure ring portion is slidably disposed on the sleeve portion and can form a locking engagement with the sleeve portion. When the folding frame is unfolded in the direction away from the sleeve portion, it forms a support portion, and the positioning pressure ring portion is located on the back side of the unfolding direction of the folding frame and forms an abutting engagement with the folding frame. When the folding frame is folded in the direction close to the sleeve portion, it can form an insertion fixed engagement with the positioning pressure ring portion.

[0008] By adopting the above technical solution, the sliding and detachable fixed connection between the main support rod and the sleeve allows the length of the support device to be adjusted according to actual needs, improving the applicability of the device. The unfolded folding frame forms a support part, which can provide effective support when the steel structure profiled steel sheet deflects downwards, preventing deformation. The abutting cooperation between the positioning pressure ring and the folding frame ensures the stability of the folding frame after unfolding, while the insertion and fixed cooperation between the folding frame and the positioning pressure ring when folded facilitates the storage and transportation of the device, improving the convenience of use.

[0009] Preferably, the sleeve includes a sleeve body and a fixing ring. The sleeve body is slidably disposed along the length direction of the main support rod and forms a detachable fixed connection with it. The fixing ring is fixedly connected to the end of the sleeve body away from the folding frame. A first fixing bolt is threaded onto the fixing ring, and the first fixing bolt passes through the sleeve body and forms an abutting fit with the main support rod.

[0010] By adopting the above technical solution, the sliding and fixed connection between the main support rod and the sleeve body makes the length of the support device adjustable, thereby adapting to the support requirements in different scenarios. The first fixing bolt threaded on the fixing ring forms an abutment fit with the main support rod to ensure structural stability, while facilitating disassembly and adjustment of position.

[0011] Preferably, the folding frame includes a ring frame fixedly connected to the end of the sleeve body and a frame rod rotatably connected to the ring frame. Multiple frame rods are evenly distributed. The positioning pressure ring abuts against the back side of all the frame rods in the unfolding direction, and any frame rod, when folded, forms an insertion and fixed fit with the positioning pressure ring.

[0012] By adopting the above technical solution, the folding frame consists of a ring frame fixed to the end of the sleeve body and multiple evenly distributed frame rods rotatably connected to the ring frame. The positioning pressure ring abuts against the back side of all the frame rods in the unfolding direction to ensure that the frame rods can maintain a stable support state when unfolded. At the same time, when the frame rods are folded up, they can form an insertion and fixed fit with the positioning pressure ring, thereby realizing the compact fixation of the folding frame in the non-use state, improving the portability and storage efficiency of the device.

[0013] Preferably, the positioning pressure ring includes a collar, and the collar is slidably disposed on the sleeve body. The collar is provided with a second fixing bolt and a pressure block. The second fixing bolt is threadedly connected to the collar and forms an abutment fit with the sleeve body. Multiple pressure blocks are provided, and each pressure block has a slot on the side near the folding frame. The frame rod is inserted into the slot after being folded up.

[0014] By adopting the above technical solution, the collar of the positioning pressure ring is slidably set on the sleeve body, so that its position can be adjusted according to actual needs. At the same time, the second fixing bolt forms an abutment fit with the sleeve body, thereby achieving precise positioning. The slot design on the multiple pressure blocks allows the frame rod to be stably inserted into the slot in the retracted state, effectively preventing the frame rod from loosening and improving the overall stability of the device.

[0015] Preferably, the main support rod has a flat portion along the axial direction, and the inner wall of the sleeve has a guide groove along the axial direction, with the main support rod and the guide groove forming an embedded sliding fit.

[0016] By adopting the above technical solution, the main support rod and the sleeve body can be effectively improved by the sliding fit of the flat part and the guide groove, thus avoiding the loosening of the connection or failure of the support due to the radial rotation between the main support rod and the sleeve body. At the same time, this design makes the length adjustment of the main support rod more precise, improving the reliability and ease of operation of the overall device.

[0017] Preferably, the end of the sleeve body near the support rod has a fixed threaded hole that forms a threaded connection with the second fixing bolt.

[0018] By adopting the above technical solution, a fixed threaded hole is opened at one end of the sleeve body near the frame rod, so that the second fixing bolt can form a threaded connection with the sleeve body through the fixed threaded hole. When the folding frame is unfolded to form a support part, the fixed threaded hole can be used to make the positioning pressure ring part stably fixed on the sleeve body, thereby improving the reliability of the overall device.

[0019] Preferably, a scale is provided on the main support rod along its length.

[0020] By adopting the above technical solution, the sliding fit between the main support rod and the sleeve body can realize the adjustment of the length of the support device, while the setting of the scale makes it easy to accurately control and read the length of the main support rod extending relative to the sleeve body, thereby improving the installation accuracy.

[0021] Preferably, a limiting rope is fixedly connected between adjacent support poles.

[0022] By adopting the above technical solution, a limiting rope is fixedly connected between adjacent support poles, which can effectively prevent excessive displacement or scattering of the support poles during the unfolding or retraction process, thereby improving the stability and reliability of the overall structure.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Through the sliding fit between the main support rod and the sleeve, the length of the support device can be adjusted according to actual needs, thus adapting to the support needs of different floor heights. Furthermore, the device can be used multiple times, significantly reducing costs and resource waste compared to traditional timber support methods.

[0025] 2. When the folding frame is unfolded, the positioning pressure ring abuts against the back side of all the frame poles in the unfolding direction, which can achieve a stable support effect, thereby effectively preventing the profiled steel sheet from deflecting and deforming during concrete pouring. At the same time, the folding frame can be folded up when not in use, and is fixed by the slot of the positioning pressure ring and the frame pole to form an interlocking fit. The structure is compact and easy to transport and store. Attached Figure Description

Detailed Implementation

[0033] The following is in conjunction with the appendix Figure 1 - Appendix Figure 6 This application will be described in further detail.

[0034] This application discloses a deflection support device for profiled steel sheets in a steel structure.

[0035] Reference Figure 1 and Figure 2 A steel structure profiled steel sheet downward deflection support device includes a main support rod 1 and sleeve parts 2 disposed at both ends of the main support rod 1. The end of any sleeve part 2 away from the main support rod 1 is fixedly connected to a folding frame 3. The sleeve part 2 includes a sleeve body 21 and a fixing ring 22. The sleeve body 21 forms a sliding fit with the main support rod 1 and forms a detachable fixed connection with it. The fixing ring 22 is fixed on the sleeve body 21 at the end away from the folding frame 3. A first fixing bolt 221 is threadedly connected to the fixing ring 22 and passes through the sleeve body 21 and abuts against the main support rod 1. A positioning pressure ring part 4 is slidably disposed on the sleeve body 21 and forms a locking fit with the sleeve body 21. When the folding frame 3 unfolds in the direction away from the sleeve body 21 to form a support part, the positioning pressure ring part 4 slides to the back side of the unfolding direction of the folding frame 3 and forms an abutment fit with the folding frame 3. When the folding frame 3 is folded in the direction close to the sleeve body 21, it can form an insertion fixed fit with the positioning pressure ring part 4.

[0036] In practical use, the sliding fit between the main support rod 1 and the sleeve body 21 allows the length of the support device to be adjusted to meet the support requirements of different floor heights, thus enabling the device to be used multiple times and avoiding resource waste. After the length is determined and adjusted, the first fixing bolt 221, which is threaded onto the fixing ring 22, passes through the sleeve body 21 and abuts against the main support rod 1 to prevent the main support rod 1 from continuing to slide inside the sleeve body 21 when the support device is working. The fixing ring 22 is set at the end of the sleeve body 21 to enhance the structural strength of the end of the tube and prevent deformation of the end of the sleeve body 21 during use. The design of the folding frame 3 at both ends, which can be unfolded and retracted, makes the support device easy to support and store. At the same time, the positioning pressure ring 4 forms an abutment fit with the folding frame 3 when it is unfolded, and forms an insertion and fixing fit with it when it is retracted, ensuring the stability of the folding frame 3 in both unfolded and retracted states.

[0037] Reference Figure 2 and Figure 3The folding frame 3 includes a ring frame 31 fixedly connected to the end of the sleeve body 21 and multiple shaft joints 32 fixedly connected to the ring frame 31. Generally, 4-6 shaft joints 32 are provided and evenly distributed on the ring frame 31. A rectangular frame rod 33 is rotatably connected to any shaft joint 32. The positioning pressure ring part 4 includes a collar 41 that forms a sliding fit with the sleeve body 21. Multiple pressure blocks 42 are integrally formed on the collar 41, and a rectangular slot 421 is opened on the side of any pressure block 42 near the support seat. The slot size of the slot 421 matches the cross-sectional size of the frame rod 33. When the folding frame 3 is unfolded, the positioning pressure ring part 4 abuts against the back side of all the frame rods 33 in the unfolding direction. At the same time, the second fixing bolt 411 threadedly connected to the collar 41 forms an abutting fit with the sleeve body 21. When the folding frame 3 is folded, the slot 421 and the frame rod 33 form an insertion fit, and the second fixing bolt 411 also forms an abutting fit with the sleeve body 21.

[0038] In practical use, the support rod 33 unfolds along the direction away from the sleeve body 21 via the shaft joint 32 to provide support. At the same time, the positioning pressure ring 4 slides on the sleeve body 21 to the back side of all the support rods 33 in the unfolding direction and abuts against it. At this time, the second fixing bolt 411 forms an abutting engagement with the sleeve body 21, thereby restricting the support rod 33 and preventing the support device from becoming unstable due to the rotation of the support rod 33 during support. When the support rod 33 retracts along the direction close to the sleeve body 2 via the shaft joint 32, the positioning pressure ring 4 slides on the sleeve body 21 to a position close to the end of the support rod 33, so that the support rod 33 and the slot 421 on the positioning pressure ring 4 form an insertion engagement. At this time, the second fixing bolt 411 also forms an abutting engagement with the sleeve body 21, thereby fixing the retracted support rod 33 and preventing the support rod 33 from opening on its own.

[0039] Reference Figure 2 and Figure 4 In other embodiments, a fixed threaded hole 211 is provided at one end of the sleeve body 21 near the frame rod 33. The second fixing bolt 411 can form a threaded connection with the sleeve body 21 through the fixed threaded hole 211. A limit rope 331 is fixedly connected between adjacent frame rods 33. In actual use, when the frame rod 33 is unfolded to provide support, the positioning pressure ring 4 abuts against the frame rod 33 and the second fixing bolt 411 forms a threaded connection with the sleeve body 21 through the fixed threaded hole 211. The threaded connection is more stable and firm, thereby ensuring that the folding frame 3 remains reliably fixed when subjected to greater pressure. In addition, the limit rope 331 can effectively prevent the frame rod 33 from excessively shifting or spreading during unfolding or retracting, thereby improving the stability and reliability of the overall structure.

[0040] Reference Figure 5 and Figure 6The main support rod 1 also includes two radially symmetrical planar portions 11 about the main support rod 1. The inner wall of the sleeve body 21 also has a corresponding guide groove 212 along the axial direction. The main support rod 1 and the guide groove 212 form an embedded sliding fit. In other embodiments, a scale 111 is provided on the two symmetrical planar portions 11 about the main support rod 1 along the length direction of the main support rod 1.

[0041] In practical use, the flat portion 11 on the main support rod 1 and the guide groove 212 in the sleeve body 21 are used to form an embedded sliding fit between the main support rod 1 and the guide groove 212, thereby preventing the main support rod 1 from rotating in the sleeve body 21, improving the stability of the overall structure, and avoiding positional deviation caused by the rotation of the main support rod 1 in the sleeve body 21. In other embodiments, a scale 111 is provided on the flat portion 11 to facilitate precise control and reading of the length of the main support rod 1 extending relative to the sleeve body 21, thereby improving installation accuracy.

[0042] The implementation principle of this application embodiment is as follows: the main support rod 1 and the sleeve body 21 form a sliding fit and a detachable fixed connection, so that the length of the support device can be adjusted according to actual needs. After the length of the support device is determined and adjusted, the first fixing bolt 221, which is threaded to the fixing ring 22, passes through the sleeve body 21 and abuts against the main support rod 1 to prevent the main support rod 1 from continuing to slide inside the sleeve body 21 when the support device is working. In addition, a fixing ring 22 is set at the end of the sleeve body 21 to enhance the structural strength of the end of the tube body and prevent the end of the sleeve body 21 from deforming during use.

[0043] When the folding frame 3 is unfolded, the support rods 33 provide support. Simultaneously, the positioning ring 4 slides onto the sleeve body 21 to the back side of all the support rods 33 in the unfolding direction and abuts against them. At this time, the second fixing bolt 411 forms an abutment fit with the sleeve body 21, preventing the support device from becoming unstable due to rotation of the support rods 33. When the folding frame 3 is folded, the positioning ring 4 slides onto the sleeve body 21 to a position near the end of the support rods 33, so that the support rods 33 and the slots 421 on the positioning ring 4 form an insertion fit. At this time, the second fixing bolt 411 also abuts against the sleeve body 21. The abutting fit is formed to fix the folded frame rod 33 and prevent it from opening on its own. In other embodiments, when the frame rod 33 is unfolded, the positioning pressure ring 4 abuts against the frame rod 33, and the second fixing bolt 411 forms a more stable threaded connection with the sleeve body 21 through the fixing threaded hole 211, ensuring that the folding frame 3 remains stable when subjected to greater pressure. At the same time, the limiting rope 331 is fixedly connected between adjacent frame rods 33 to prevent the frame rod 33 from excessively shifting or spreading during unfolding or folding, thereby improving the stability and reliability of the overall structure.

[0044] The flat portion 11 on the main support rod 1 engages with the guide groove 212 inside the sleeve body 21, forming an embedded sliding fit between the main support rod 1 and the guide groove 212. This prevents the main support rod 1 from rotating inside the sleeve body 21 and avoids positional deviations caused by the rotation of the main support rod 1 inside the sleeve body 21. In other embodiments, the scale 111 on the flat portion 11 facilitates precise control and reading of the length of the main support rod 1 extending relative to the sleeve body 21, thereby improving installation accuracy.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
