Description

Technical Field

[0001] This application relates to the technical field of building construction, and in particular to a steel structure spiral ramp mounting bracket. Background Technology

[0002] With the development of the national economy and technology, the shapes of more and more public buildings are becoming more and more unique. In order to maintain the overall aesthetics and harmony of the project, and to take into account the characteristics of high traffic flow in public places, a steel structure spiral ramp with beautiful shape, high load-bearing capacity, light weight and quick installation is adopted.

[0003] The steel spiral ramp rises in a spiral shape and tapers layer by layer, resulting in a complex design and low structural redundancy. Furthermore, due to limitations in lifting machinery, the ramp consists of numerous segments. Controlling installation accuracy, minimizing dimensional errors, and ensuring the overall aesthetic appeal during installation posed a significant challenge to the construction team.

[0004] In the process of realizing this utility model, the inventors discovered the following problems with the existing technology: 1. The installation of steel structure spiral ramps is cumbersome, and special tools are often required for installation and disassembly, which makes installation inconvenient; 2. There are poor precision and low accuracy in the installation process, which leads to errors in the installation and docking process and affects the installation efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a steel structure spiral ramp installation bracket to solve the problems mentioned in the background art, such as the inconvenience of installation due to the large number of installation and disassembly tools and the low accuracy during installation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a steel structure spiral ramp installation bracket, including a base, an upper ramp single-tube support rod fixedly connected to the top of the base, a single-tube connecting rod fixedly connected to one side of the upper ramp single-tube support rod, a lower ramp single-tube support rod fixedly connected to the other end of the single-tube connecting rod, an upper ramp support frame fixedly connected to the top of the upper ramp single-tube support rod, upper ramp locking blocks fixedly connected to both sides of the upper ramp support frame, and a rolling slide embedded in the top of the upper ramp support frame. The trough has a pulley slidably connected inside, and an upper ramp clamping plate is rotatably connected to the pulley. A lower ramp support frame is fixedly connected above the lower ramp single-tube support rod. Lower ramp clamping blocks are fixedly connected to both sides of the lower ramp support frame. A lower ramp clamping plate is slidably connected inside the lower ramp support frame. A lifting support rod is fixedly connected above the base. A threaded locking ring is threadedly connected to the top of the lifting support rod. A telescopic rod is sleeved inside the threaded locking ring. A hand chain hoist is fixedly connected to the other end of the telescopic rod.

[0007] More preferably, the single-tube support rod of the uphill ramp is fixedly connected to the single-tube connecting rod of the downhill ramp to form a fixed connection structure, and the single-tube connecting rod is parallel to the base.

[0008] More preferably, the chute is fixedly connected by the cooperation between the embedded ramp support frame and the ramp locking block.

[0009] More preferably, the ramp plate forms a sliding connection structure through the cooperation between the rotating connecting pulley and the sliding groove.

[0010] More preferably, the upper ramp plate and the upper ramp block are attached to each other and are parallel to the lower ramp plate that is attached to the lower ramp block.

[0011] More preferably, the telescopic rod forms a threaded connection structure through the engagement between the threaded locking ring and the lifting support rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. By adding a single-tube connecting rod between the single-tube support rods on the uphill and downhill slopes, the two single-tube support rods can be effectively reinforced, stabilizing the overall structure during installation and preventing wobbling that could affect installation accuracy.

[0014] 2. Adding ramp clips to the ramp support frame to connect the spiral ramp to be installed makes it easy to fix the spiral ramp during operation. After welding, the entire mounting bracket can be easily disassembled. Alternatively, the clips can be replaced with hinges, which can achieve the same purpose. Therefore, hinge connection can be implemented as an alternative solution.

[0015] 3. Adding a chute to the ramp support frame can effectively move the ramp plate longitudinally. Because the spiral ramp has a longitudinal angle difference, the pulley sliding in the chute can effectively move the ramp plate to the upper spiral ramp position to stabilize the installation process.

[0016] 4. The parallel movement of the upper and lower ramp plates and the coordinated longitudinal movement of the chute pulleys effectively fixes the upper and lower parts of the spiral ramp, making it suitable for multi-angle operation.

[0017] 5. A hand chain hoist is added to the top of the mounting bracket to lift the spiral ramp for installation. At the same time, the longitudinal telescopic rod added to the hand chain hoist is fixed in length by a threaded locking ring, which can effectively match the angle of the spiral ramp to make the installation process more stable.

[0022] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 This application will be described in further detail.

[0023] This application discloses a steel structure spiral ramp mounting bracket.

[0024] like Figure 1-3 As shown, this utility model provides a steel structure spiral ramp installation bracket, including a base 1. An upper ramp single-tube support rod 2 is fixedly connected to the top of the base 1. A single-tube connecting rod 4 is fixedly connected to one side of the upper ramp single-tube support rod 2, and a lower ramp single-tube support rod 3 is fixedly connected to the other end of the single-tube connecting rod 4. An upper ramp support frame 5 is fixedly connected to the top of the upper ramp single-tube support rod 2. Upper ramp locking blocks 6 are fixedly connected to both sides of the upper ramp support frame 5. A sliding groove 7 is embedded in the top of the upper ramp support frame 5, and the interior of the sliding groove 7 is slidably connected... There is a pulley 8, which is rotatably connected to an upper ramp clamping plate 9. A lower ramp support frame 10 is fixedly connected above the lower ramp single tube support rod 3. Lower ramp clamping blocks 11 are fixedly connected to both sides of the lower ramp support frame 10. A lower ramp clamping plate 12 is slidably connected inside the lower ramp support frame 10. A lifting support rod 13 is fixedly connected above the base 1. A threaded locking ring 15 is threadedly connected to the top of the lifting support rod 13. A telescopic rod 14 is sleeved inside the threaded locking ring 15. A hand chain hoist 16 is fixedly connected to the other end of the telescopic rod 14.

[0025] like Figure 1 As shown, the single-tube support rod 2 of the uphill ramp is fixedly connected to the single-tube connecting rod 4 of the downhill ramp by cooperating with the single-tube support rod 3 of the downhill ramp to form a fixed connection structure. The single-tube connecting rod 4 is parallel to the base 1. The method of adding the single-tube connecting rod 4 between the single-tube support rod 2 of the uphill ramp and the single-tube support rod 3 of the downhill ramp can effectively strengthen the two single-tube support rods. During the installation process, the overall structure is stable and does not easily shake, thus affecting the installation accuracy.

[0026] like Figure 1 and Figure 3 As shown, the chute 7 forms a fixed connection structure through the cooperation between the embedded upper ramp support frame 5 and the upper ramp locking block 6. The upper ramp locking block 6 is added to the upper ramp support frame 5 to connect the spiral ramp to be installed, which can easily fix the spiral ramp during operation. When the welding is completed, the entire mounting bracket can also be easily disassembled. At the same time, the locking block can be replaced with a hinge. The same purpose can be achieved through the hinge connection. Therefore, the hinge connection can be implemented as an alternative solution.

[0027] like Figure 1 and Figure 3 As shown, the upper ramp plate 9 forms a sliding connection structure through the cooperation between the rotating connecting pulley 8 and the sliding groove 7. The addition of the sliding groove 7 to the upper ramp support frame 5 can effectively enable the upper ramp plate 9 to move longitudinally. Because there is a longitudinal angle difference in the spiral ramp, the upper ramp plate 9 can be effectively moved to the upper spiral ramp position by the sliding of the pulley 8 in the sliding groove 7 to stabilize the installation process.

[0028] like Figure 1 and Figure 3 As shown, the upper ramp plate 9 and the upper ramp block 6 are in contact with each other and are parallel to the lower ramp plate 12 that is in contact with the lower ramp block 11. The parallel movement of the upper ramp plate 9 and the lower ramp plate 12, along with the coordinated longitudinal movement of the slide groove 7 and pulley 8, can effectively fix the upper and lower parts of the spiral ramp, making it suitable for multi-angle operation.

[0029] like Figure 1 and Figure 2 As shown, the telescopic rod 14 forms a threaded connection structure with the lifting support rod 13 through the engagement of the threaded locking ring 15. A hand chain hoist 16 is added to the top of the mounting bracket to lift the spiral ramp for installation. At the same time, the longitudinal telescopic rod 14 added by the hand chain hoist 16 is fixed in length by the threaded locking ring 15, which can effectively match the angle of the spiral ramp to make the installation process more stable.

[0030] The usage and advantages of this utility model: The working process of this steel structure spiral ramp mounting bracket is as follows:

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, first move the mounting bracket to the ramp segment where the spiral ramp needs to be installed. Through model design, find the center of gravity of the ramp segment to be installed and calculate the height difference between the four lifting points.

[0032] Then, four steel wire ropes of the same length are used and a hand chain hoist 16 is set up to facilitate the adjustment of the ramp segment angle, so that the hook is as close as possible to the center of gravity of the diagonal brace. The hand chain hoist 16 is adjusted so that the ramp segment reaches its required installation angle. The lifting position of the hand chain hoist 16 is adjusted by adjusting the length of the telescopic rod 14, and the position is locked by the threaded locking ring 15, and then lifted to the designated position.

[0033] Next, move the upper ramp plate 9 and the lower ramp plate 12 to a position vertically below the hoisting spiral ramp, place the spiral ramp on the upper ramp plate 9 and the lower ramp plate 12, and fix the position of the spiral ramp by the upper ramp block 6 and the lower ramp block 11.

[0034] Finally, six reflective sheets are pasted around each section of the ramp, and the position and height are controlled using a total station. After the positioning is confirmed, the connection between the ramp sections is welded. After the connection between the sections is completed, the hooks are released to install the next ramp section.

[0035] 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.
