Description

Technical Field

[0001] This utility model belongs to the field of waterproof construction, and in particular relates to a waterproof membrane support tool. Background Technology

[0002] When applying waterproof membrane to the side walls of a structure, the membrane needs to be laid downwards from the top of the structure. Sometimes, two workers lift the membrane from the top while others pull it down from below. Because the membrane is heavy, this method is labor-intensive, requires many workers, and is costly. Various waterproof membrane support devices exist to address this issue, but most are complex in structure, require counterweights, and involve cumbersome installation procedures. Summary of the Invention

[0003] The problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a waterproof membrane support tool.

[0004] This invention is achieved through the following technical solution:

[0005] A waterproof membrane support tool includes a bottom frame with omnidirectional brake wheels. Support columns are vertically positioned upwards at the left and right ends of the rear of the bottom frame, with symmetrically welded arc-shaped hooks on the support columns. A movable shaft is placed on each arc-shaped hook. Support frames are symmetrically welded forward at the left and right ends of the front of the bottom frame. Each support frame includes a horizontal support rod and an oblique support rod. The oblique support rods are angled upwards, and the angle between the oblique support rods and the horizontal support rods is obtuse. The horizontal support rods are welded to the bottom frame. Bearings are welded to the upper ends of the oblique support rods. A rotating shaft is installed between the two bearings, allowing the rotating shaft to rotate within the bearings. The height of the rotating shaft is higher than the height of the movable shaft.

[0006] Preferably, the angle between the inclined support rod and the horizontal support rod is 120°-150°.

[0007] Preferably, the arc-shaped hook is an iron bent hook.

[0008] The tool of this invention has a simple structure, is easy to operate, is lightweight, and is easy to move. It does not require counterweight, as the waterproof membrane itself can act as counterweight, reducing the steps of placing and removing counterweight. It is simple and practical, and has more practical applications than existing support devices. Attached Figure Description

[0011] Figure 3 This is a schematic diagram of the structure after removing the movable shaft in this embodiment.

[0012] In the diagram, 1 is the bottom frame, 2 is the omnidirectional brake wheel, 3 is the support column, 4 is the arc-shaped hook, 5 is the movable shaft, 6 is the horizontal support rod, 7 is the diagonal support rod, 8 is the bearing, and 9 is the rotating shaft. Detailed Implementation

[0013] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0014] This embodiment includes a bottom frame 1, which is a rectangular frame. A universal brake wheel 2 is provided on the bottom frame 1. The bottom frame 1 can be moved by the universal brake wheel 2, and the bottom frame 1 can also be stopped by the braking function of the universal brake wheel 2.

[0015] Support columns 3 are vertically installed at the left and right ends of the rear of the bottom frame 1. Symmetrically welded arc-shaped hooks 4, made of bent iron, are mounted on the support columns 3. Movable shafts 5 are placed on the arc-shaped hooks 4, and these shafts are used to thread waterproof membrane. After the waterproof membrane is fitted onto the movable shafts 5, it can rotate around them. The support columns 3 not only support the arc-shaped hooks 4 but also act as pushers for the bottom frame 1; grasping the support columns 3 allows the bottom frame 1 to be moved.

[0016] Symmetrical support frames are welded forward at both ends of the front of the bottom frame 1. Each support frame includes a horizontal support rod 6 and an inclined support rod 7. The horizontal support rod 6 is welded to the bottom frame 1, and the inclined support rod 7 extends obliquely upward and forward from the bottom frame 1. The angle between the inclined support rod 7 and the horizontal support rod 6 is obtuse, preferably 120°-150°. A bearing 8 is welded to the upper end of the inclined support rod 7, and the outer ring of the bearing 8 is welded to the inclined support rod 7. The outer ring of the bearing 8 cannot rotate. A rotating shaft 9 is installed between the two bearings 8 on the two inclined support rods 7, allowing rotation within the bearings 8. The height of the rotating shaft 9 is higher than the height of the movable shaft 5, which improves the stability of the entire support tool during construction.

[0017] During construction, the bottom frame 1 is placed on the top surface of the structure and pushed to the edge of the top surface. The rotating shaft 9 extends forward slightly beyond the top edge of the structure, stopping the bottom frame 1. The waterproof membrane is then fitted onto the movable shaft 5, which is then placed on the arc-shaped hook 4. A section of the waterproof membrane is pulled forward and draped upward over the rotating shaft 9, then allowed to hang naturally after passing over the shaft 9. Workers at the side walls of the structure pull the waterproof membrane, and then the waterproof membrane is laid step by step. Using this embodiment, the tool eliminates the need for manual installation of the waterproof membrane and the need for counterweights, as the waterproof membrane itself acts as a counterweight, preventing the tool from tipping forward. The waterproof membrane is easy to install, the bottom frame 1 has a simple structure, is lightweight, easy to move, and simple and convenient to operate.

[0018] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; those skilled in the art should understand that modifications can still be made to the technical solutions described in the above embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
