Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a limiting support mechanism for a support frame. Background Art

[0002] With the gradual development of building construction, long-span trusses are used more frequently. Due to the long length and large mass of long-span trusses, in order to facilitate the construction of trusses more conveniently, in actual construction, trusses are generally spliced in segments. To facilitate the construction of trusses more conveniently, a relatively common existing truss construction method is to hoist the segmented trusses to the corresponding installation positions through hoisting equipment to complete the splicing of multiple segmented trusses. During the splicing process, it is usually necessary to use a support frame to support the segmented trusses. The support frame is generally arranged on a roadbed box. In order to prevent the support frame from sliding on the roadbed box and affecting the truss splicing, the support frame is generally limited.

[0003] The relatively common existing limiting method is to set a clamping plate on the support frame and then weld the clamping plate to the roadbed box so that the roadbed box and the support frame are connected into a whole, so that the support frame will not slide or shift on the roadbed box before the splicing is completed. However, although the support frame can be more stable by setting the clamping plate to clamp the support frame and welding the clamping plate to the roadbed box, additional welding work is required when limiting the support frame, and when the support frame is removed after the truss splicing is completed, a cutting tool is also required to cut off the clamping plate connected between the roadbed box and the support frame, which greatly increases the workload of construction workers.

In addition, the terms "first" and "second" are only used for distinction in description and do not have special meanings.

[0031] Since the more commonly used existing way to limit the support frame is to set a clamping plate on the support frame and then weld the clamping plate to the roadbed box, making the splicing of the truss segments more stable. However, after the truss splicing is completed, a cutting tool is still needed to cut off the clamping plate connected between the roadbed box and the support frame before the support frame can be removed, which greatly increases the workload of the construction workers.

[0032] Therefore, this embodiment provides a support frame limiting and supporting mechanism. On the one hand, it is more convenient to use it to limit the support frame and can limit the six degrees of freedom of the support frame. On the other hand, after the truss splicing is completed, the support frame can be removed without using a cutting tool to disconnect the connection between the support frame and the roadbed box, reducing the workload of the construction workers.

[0033] Please refer to Figures 1 - 4, A limiting support mechanism for a support frame includes a roadbed box 1, a clamping member 2, and a limiting component. The support frame 100 is placed on the roadbed box 1, the limiting component is installed on the roadbed box 1, the clamping member 2 clamps the support frame 100, and the limiting component limits the clamping member 2, thereby realizing the limitation of the support frame 100.

[0034] Further, please refer to Figure 1 and Figure 2 , the support frame 100 has four support columns 101, and the four support columns 101 are all placed on the upper cover plate of the roadbed box 1. The four support columns 101 are arranged at the four corners, and the support column 101 is provided with a plug-in member 1001. The clamping member 2 is clamped to the plug-in member 1001 to limit the support column 101 and prevent the support frame 100 from shaking.

[0035] Preferably, the plug-in member 1001 is cylindrical and welded to the support column 101.

[0036] Further preferably, the plug-in member 1001 is arranged in the lower region of the support column 101, and the bottom surface of the plug-in member 1001 is flush with the bottom of the support column 101, that is, the bottom surface of the plug-in member 1001 is attached to the upper cover plate of the roadbed box 1.

[0037] In this embodiment, plug-in members 1001 are provided on both side surfaces of the support column 101 facing away from the other support columns 101. Appropriately, the plug-in members 1001, the clamping members 2, and the limiting components correspond one by one. The clamping member 2 is clamped to the plug-in member 1001, and the limiting component limits the clamping member 2, pressing against each support column 101 in two directions to provide a supporting force for the four support columns 101 to approach each other, preventing the support columns 101 from shaking and improving the stability of the support frame 100.

[0038] Optionally, a plurality of plug-in members 1001 can also be evenly spaced around the support column 101. Appropriately, the plug-in members 1001, the clamping members 2, and the limiting components correspond one by one. The clamping member 2 is clamped to the plug-in member 1001, and the limiting component limits the clamping member 2, pressing against each support column 101 in four directions to provide a supporting force for the four support columns 101 to approach each other, preventing the support columns 101 from shaking and further improving the stability of the support frame 100.

[0039] Further, please refer to Figure 3 , the clamping member 2 includes a connected clamping plate 21 and a limiting plate 22, and the clamping plate 21 and the limiting plate 22 are arranged in an L shape. The clamping plate 21 is provided with a first clamping hole 211. The plug-in member 1001 extends into the first clamping hole 211 and circumferentially abuts against the hole wall of the first clamping hole 211, and the clamping plate 21 is closely attached to the support column 101 to increase the contact area with the support column 101.

[0040] Further, please refer to Figure 3 and Figure 4 . The limiting plate 22 is provided with a second clamping hole 221. The second clamping hole 221 communicates with the first clamping hole 211. During the process of the plug-in member 1001 extending into the first clamping hole 211, the bottom of the plug-in member 1001 gradually extends into the second clamping hole 221 until the circumferential wall of the plug-in member 1001 abuts against the hole wall of the second clamping hole 221, further increasing the contact area with the support column 101.

[0041] The limiting assembly includes an abutting plate 31 and a pressing plate 32. The abutting plate 31 abuts against one end of the limiting plate 22 away from the clamping plate 21, capable of restricting two degrees of freedom of the support column 101. The pressing plate 32 is arranged on the side of the abutting plate 31 close to the limiting plate 22, and the pressing plate 32 is slidably arranged on the abutting plate 31 in the vertical direction. During the splicing process of the truss, the pressing plate 32 moves downward to press the limiting plate 22, capable of restricting four degrees of freedom of the support column 101. After the splicing of the truss is completed, the pressing plate 32 rises to release the limiting plate 22, and the support frame 100 is removed.

[0042] Exemplarily, the abutting plate 31 is welded to the upper cover plate of the roadbed box 1. Further optionally, a clamping groove is provided on the upper cover plate, and the abutting plate 31 is clamped in the clamping groove.

[0043] In other feasible embodiments, the abutting plate 31 is slidably arranged on the upper cover plate of the roadbed box 1.

[0044] The limiting assembly further includes a driving unit for driving the pressing plate 32 to rise or fall on the abutting plate 31.

[0045] This embodiment provides a driving method for the pressing plate 32. Specifically, the driving unit includes a first driving member, a lead screw nut 33 and a lead screw 34. The first driving member is installed on the upper cover plate or the abutting plate 31. The lead screw nut 33 is screwed onto the lead screw 34, and the lead screw nut 33 is fixedly connected to the pressing plate 32. The first driving member is configured to drive the lead screw nut 33 to rotate axially, so that the lead screw nut 33 drives the pressing plate 32 to rise or fall.

[0046] The first driving member can be a rotary cylinder or a rotary motor.

[0047] In other feasible embodiments, the driving unit may further include a second driving member. The second driving member is installed on the upper cover plate or the abutting plate 31, and the output end of the second driving member is drivingly connected to the pressing plate 32. The second driving member is configured to directly drive the pressing plate 32 to rise or fall.
