Abstract
Description
Technical Field
[0001] This utility model relates to scaffolding, specifically a fixing device for clamping uprights on cantilever scaffolding. Background Technology
[0002] As one of many types of scaffolding, cantilevered steel pipe scaffolding has been widely used in construction for many years, especially in the construction of medium and high-rise buildings, and has become the most common and mature traditional safety maintenance facility.
[0003] In the construction of cantilever scaffolding, different types of I-beams are selected as cantilever beams according to the design requirements, and the upper scaffolding uprights are erected on them. The traditional construction method is to pre-determine the position of the uprights on the cantilever beams, and then directly position and weld steel pipes or weld short steel bars to the upper part of the I-beams at that point, and then fit the uprights onto the short steel bars. Once the position of the uprights is fixed, it cannot be adjusted. The position of the scaffolding uprights can only be adjusted during construction by adjusting the position of the cantilever section and the anchoring section of the steel section. The error tolerance is low. In addition, the welding operation will burn the I-beams and steel pipes, resulting in material damage that cannot be recycled. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a fixing device for the uprights of a cantilever frame, thereby solving the problems mentioned in the background art, such as the inability to adjust the position of the uprights and the inability to recycle damaged materials.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A fixing device for a disc-lock upright on a cantilever frame includes a top support screw rod, a top support plate, and a disc-lock steel pipe. One end of the top support screw rod is fixedly connected to the top support plate, and the top support plate is clamped onto the cantilever I-beam. The other end of the top support screw rod is screwed to the disc-lock steel pipe.
[0007] Preferably, a pair of clamping plates are provided at opposite ends of the bottom of the top support plate, and a pair of pads are clamped between the pair of clamping plates at both ends of the top support plate and the end of the wing plate of the cantilever I-beam, which makes the installation and disassembly of the top support plate convenient, improves the material turnover rate, and reduces the loss cost.
[0008] Preferably, the pair of clamping plates are symmetrical about the long axis of the cantilevered I-beam, which facilitates the use of pads to ensure that the top support plate is securely installed on the cantilevered I-beam.
[0009] Preferably, the outer surface of the top support screw is provided with an external thread, and the inside of the disc buckle steel pipe is provided with an internal thread that mates with the external thread.
[0010] Preferably, the bottom of the disc buckle steel pipe is provided with a flared tube, the inner diameter of which is larger than the outer diameter of the top support screw.
[0011] Preferably, a pair of top support adjustment members are provided on opposite sides of the outside of the flared tube.
[0012] Preferably, the axis of the top support screw is located along the long axis of the cantilevered I-beam.
[0013] Preferably, the pad is a wooden pad or a rubber pad.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. This device can be used to fix the disc-lock uprights on cantilever scaffolds. It is made by placing the top support plate on the cantilever I-beam, and then ensuring that the cantilever I-beam is centered on the top support plate. Then, a movable wooden wedge is inserted into the gap between the side wing plate of the top support plate and the steel flange of the cantilever I-beam. After ensuring that the connection between them is secure, the disc-lock steel pipe is then sleeved on the top support screw. Then, the top support adjuster is adjusted according to the needs of the construction site to move the disc-lock steel pipe to the appropriate position, thereby completing the fixation of the uprights and the bottom.
[0016] 2. This device can be used to fix the disc-lock uprights on cantilever scaffolds. The height is adjusted and connected to the disc-lock steel pipe and the top support screw through threads. Therefore, the disc-lock steel pipe can be easily removed from the top support screw. Then, the cantilever I-beam and the top support plate are locked together by movable wooden wedges. This allows the cantilever I-beam and the top support plate to be easily removed, thus enabling better reuse and reducing wear and tear costs. Attached Figure Description

[0021] 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.
[0022] Example 1:
[0023] Please refer to the following: Figure 1-3 This embodiment provides a fixing device for the disc-lock uprights on a cantilever frame. One end of the top support screw 1 is fixedly connected to the top support plate 2, and the top support plate 2 is clamped onto the cantilever I-beam 5; the other end of the top support screw 1 is screwed to the disc-lock steel pipe 3. The cantilever I-beam 5 is part of the cantilever frame.
[0024] A pair of clamping plates are arranged opposite each other at both ends of the bottom of the top support plate 2. A pair of pads are clamped between the pair of clamping plates at both ends of the top support plate and the end of the flange of the cantilever I-beam. There is a gap between the end of the flange of the cantilever I-beam 5 and the pair of clamping plates at both ends of the top support plate 2. The pads are clamped in the gap, and the pads are interference fit with the side wall of the gap, so that the top support plate is clamped on the cantilever I-beam. This not only fixes the top support plate, but also facilitates the removal of the top support plate. The pads are made of wood or rubber. The pads ensure that the top support plate 2 is firmly installed on the cantilever I-beam 5 and is easy to remove, which improves the turnover rate of the top support plate 2 and reduces the cost of loss.
[0025] The bottom of the disc-lock steel pipe 3 is provided with a flared tube. The inner diameter of the flared tube is larger than the outer diameter of the top support screw rod 1, which makes it easier to put the disc-lock steel pipe 3 onto the top support screw rod 1 for screwing and improves the installation efficiency. The disc-lock upright is put onto the disc-lock steel pipe 3, and its bottom abuts against the flared tube.
[0026] The surface of the top support screw 1 is provided with external threads, and the inner end of the disc steel pipe 3 is provided with internal threads. The disc steel pipe 3 and the top support screw 1 are connected by the engagement of internal and external threads, which facilitates quick adjustment of the height of the disc steel pipe 3. The axis of the top support screw is located in the direction of the long axis of the cantilever I-beam.
[0027] The cantilevered I-beam 5 is located in the center of the top support plate 2. Ideally, the pair of clamping plates should be symmetrical about the long axis of the cantilevered I-beam 5, so that the top support plate 2 is subjected to relatively symmetrical forces, which also facilitates the installation of the pad plate and improves its stability.
[0028] In other embodiments, a pair of top support adjustment pieces 4 are provided on opposite sides of the flared tube to facilitate adjustment of the height of the disc buckle steel pipe 3, so as to facilitate the positioning and installation of the disc buckle upright.
[0029] Working principle: When positioning and fixing the disc buckle upright, place the top support plate 2 and the top support screw 1 on the cantilevered I-beam 5, ensuring that the cantilevered I-beam 5 is centered on the top support plate 2. Then, insert the pad 6 into the gap between the pair of clamping plates at both ends of the top support plate 2 and the end of the flange of the cantilevered I-beam 5 to ensure a stable connection between the top support plate 2 and the cantilevered I-beam 5. Next, sleeve the disc buckle steel pipe 3 on the top support screw 1, and then rotate the disc buckle steel pipe 3 or the top support adjustment piece 4 on the disc buckle steel pipe 3 according to the needs of the construction site to adjust the height of the disc buckle steel pipe 3, so that the disc buckle steel pipe 3 moves to a suitable position to complete the positioning and installation of the disc buckle upright and the fixing of the bottom of the disc buckle upright. When it is necessary to adjust the position of the disc buckle upright, the top support plate 2 can be quickly removed and the installation position changed, making it extremely convenient to adjust the position of the disc buckle upright.
[0030] This utility model has the following beneficial technical effects: By installing the top support plate on the cantilevered I-beam in a snap-fit manner, it can ensure both the stable installation of the top support plate and its quick removal from the cantilevered I-beam; the disc buckle upright is sleeved on the disc buckle steel pipe, and the disc buckle steel pipe is screwed to the top support screw, allowing for adjustment of the height of the disc buckle steel pipe for positioning and installation fixation of the disc buckle upright; the bottom of the disc buckle steel pipe is provided with a flared tube for quick installation, and the flared tube is also provided with a top support adjustment component for quick rotation of the disc buckle steel pipe, improving the efficiency of installation and disassembly; since the above structure adopts a non-welded connection, installation and disassembly are convenient, so the above structure can be reused, reducing material consumption costs; moreover, the disc buckle upright and the top support screw do not directly contact each other, reducing the wear of the top support screw and effectively realizing the installation, fixation, and position adjustment of the disc buckle upright.
[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
