DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Example: Figure 1-3As shown, the utility model provides a waterproof device for construction engineering, including a base plate 1, one end of the upper surface of the base plate 1 is fixedly provided with a vertically arranged upright plate 11, and the side wall of the upright plate 11 is rotatably provided with a horizontally arranged placement roller 12, and the end of the base plate 1 away from the upright plate 11 is movably inserted with a placement plate 2 arranged in an inverted U shape, and the two ends of the bottom of the placement plate 2 are located on the lower surface of the base plate 1 and are rotatably provided with a first limiting roller 21, an adjustment component is provided between the placement plate 2 and the base plate 1, a through groove 3 is penetrated at the middle end of the base plate 1, and two symmetrically distributed second limiting rollers 31 are rotatably provided in the through groove 3, and an inverted U-shaped bracket 32 ​​is fixedly provided at one end of the through groove 3 close to the placement plate 2, and a cutting blade 33 is slidably provided on the bracket 32.

[0018] The adjusting assembly includes a screw rod 22, which is threadedly arranged at the middle end of the placement plate 2, and the bottom of the screw rod 22 is rotatably arranged on the bottom plate 1. A rotating wheel 23 is fixedly arranged at the top of the screw rod 22. The screw rod 22 can be driven to move the placement plate 2 with the thread set, thereby driving the placement plate 2 to move up and down along the screw rod 22, thereby limiting the first limiting rod, so that the first limiting roller 21 can effectively resist the coiled material so that it is against the roof ground to be laid, thereby ensuring the uniformity of laying. The arranged rotating wheel 23 can facilitate the staff to directly drive the screw rod 22 to rotate, which is convenient for the staff to operate.

[0019] A slide groove 34 is provided on the top of the bracket 32, and a slider 35 is slidably provided in the slide groove 34. Two symmetrically distributed columns 36 are fixed on the top of the blade 33, and the tops of the two columns 36 pass through the slider 35. The provision of the slider 35 and the column 36 allows the staff to stably pull the blade 33 to move, so that the blade 33 cuts the laid coiled material, so that the cut coiled material can be laid completely. A fixing block 38 is fixed at one end of the two columns 36 passing through the slider 35. The column 36 is located above the bracket 32 ​​and is sleeved with a return spring 37. The two ends of the return spring 37 are respectively against the bracket 32 ​​and the fixed block 38. The provision of the return spring 37 can prevent the blade 33 from falling and contacting and scratching the coiled material when the coiled material is being laid.

[0020] A thread groove 13 is formed at one end of the placement roller 12 away from the vertical plate 11, and a positioning plate 14 is threadedly provided on the thread groove 13. The positioning plate 14 can limit the coil mounted on the placement roller 12 to prevent the coil from falling off due to unrestricted position when the device is used.

[0021] Universal wheels 4 are installed at the four corners of the side wall of the base plate 1. The universal wheels 4 can facilitate the overall movement of the device and improve practicality. A slanted hand carriage 5 is fixedly arranged on one end of the upper surface of the base plate 1 close to the vertical plate 11. The hand carriage 5 can facilitate the staff to pull the device to move and facilitate operation.

[0022] Working principle: In actual use, the waterproof coiled material to be laid is inserted into the placement roller 12, and the positioning plate 14 is rotated to make it move along the threaded groove 13, so that the positioning plate 14 can limit the coiled material sleeved on the placement roller 12 to prevent the coiled material from falling off due to unrestricted positioning when the device is used. Then the staff can first pull one end of the coiled material through the two second limiting rollers 31 and then pull it to the bottom of the first limiting roller 21, aligning its end with the starting point to be laid. At this time, rotating the screw rod 22 can make the placement plate 2 move up and down along the screw rod 22, so that the first limiting roller 21 can effectively resist the coiled material and make it resist the roof ground to be laid. At this time, the hand push frame 5 is used to pull the device to move, so that the waterproof coiled material can be laid by itself, so that the roof can be waterproofed, which improves the convenience of laying waterproof coiled material.

[0023] When the coil needs to be cut at one end of the laying, the staff can directly press down the column 36 to make the blade 33 contact the coil, and then the staff pulls the column 36 to move along the slide 34. At this time, the blade 33 will cut the coil, and the staff does not need to look for tools everywhere to cut the coil completely.

[0024] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
