Technical Field
[0001] This utility model relates to the field of waterproof construction, specifically a waterproof membrane laying device. Background Technology
[0002] Waterproof membrane is a flexible building material product that can be rolled up, with asphalt or polymer-based waterproof materials impregnated on a substrate. It is mainly used in building walls and roofs to resist external rainwater and groundwater seepage. Waterproof membrane is the first line of defense in the entire waterproofing project and plays a crucial role in the overall waterproofing process. Waterproof membranes are divided into two types according to the application method: cold-applied and hot-applied. Hot-applied waterproof membranes require heating the application surface during application, while cold-applied waterproof membranes are self-adhesive, with an isolation layer separating the adhesive layer of the waterproof membrane. To improve the efficiency, convenience, and environmental friendliness of construction, cold-applied waterproof membranes have been widely used.
[0003] A search revealed a patent document with publication number CN220976016U, which discloses a waterproof membrane laying device. The device includes a frame body with a fixed connecting rod fixedly connected to its inner top. The fixed connecting rod has several threaded through holes on its surface. A movable sleeve block is movably fitted onto the outer surface of the fixed connecting rod. Positioning bolts are movably connected to the inside of the movable sleeve block and the inner side of the threaded through holes. A connecting handle is fixedly connected to one side of the movable sleeve block. This waterproof membrane laying device, through the mutual transmission between the active bevel gear, the connecting transmission mechanism, and the first driven bevel gear, enables the pressure roller to press down and tighten the waterproof membrane body during rotational laying, while the take-up roller rotates stably. This allows for stable winding of the isolation layer of the waterproof membrane body, ensuring stable laying of the waterproof membrane body.
[0004] While the existing technology can facilitate the laying of waterproof membranes, it has been found in application that the width of the waterproof membrane is fixed, and in some cases, the laid waterproof membrane exceeds the edge and needs to be cut. The existing technology can only be used for direct laying of the membrane. Therefore, a new waterproof membrane laying device is proposed to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a waterproof membrane laying device to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:

A waterproof membrane roll is assembled and installed in the middle of the arms. Vertical frames are symmetrically fixedly connected between the arms and the pressure roller corresponding to the waterproof membrane roll. Two horizontal bars are fixedly connected in parallel between the vertical frames. A knife holder is assembled and installed on the horizontal bars. A cutter is fixedly installed on the knife holder by a first bolt. A storage groove is fixedly connected between the vertical frames and the pressure roller corresponding to the two arms.
[0008] As a further embodiment of this utility model: the waterproof membrane roll is threaded onto the mounting shaft, and two conical clamps are fixedly installed on the mounting shaft at both ends of the waterproof membrane roll by the second bolts. The conical clamps are clamped on the inner cavity of the waterproof membrane roll.
[0009] As a further embodiment of this utility model: one end of the mounting shaft is hinged to the first rotating seat, and the other end of the mounting shaft is fixedly mounted on the second rotating seat by a third bolt. Both the second rotating seat and the first rotating seat are rotatably mounted to the boom.
[0010] As a further improvement of this utility model: both ends of the tool holder are provided with open clamping grooves that are adapted to the crossbar, and the openings of the open clamping grooves are locked by a fourth bolt.
[0011] As a further improvement of this utility model: the blade holder is provided with a groove corresponding to and adapted to the cutting blade, and the first bolt passes through both the cutting blade and the blade holder.
[0012] As a further embodiment of this utility model: the bottom surface of the boom is fixedly connected to an auxiliary support leg that is inclined thereto, and the auxiliary support legs are rotatably connected together by an auxiliary roller.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This utility model involves passively unwinding the waterproof membrane roll. The entire device is moved by pushing the handle, and the pressure roller presses the waterproof membrane onto the ground for laying.

[0023] 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.
[0024] Please see Figs. 1-5 In this embodiment of the utility model, a waterproof membrane laying device includes symmetrically arranged arms 1, with pressure rollers 2 rotatably connected between the bottom ends of the arms 1, and handles 3 fixedly connected between the top ends of the arms 1. A waterproof membrane roll 4 is assembled and installed in the middle of the arms 1. A vertical frame 5 is symmetrically fixedly connected between the arms 1 and the pressure rollers 2 corresponding to the waterproof membrane roll 4. Two horizontal bars 6 are fixedly connected in parallel between the vertical frames 5. A knife holder 7 is assembled and installed on the horizontal bars 6. A cutter 9 is fixedly installed on the knife holder 7 by a first bolt 8. A storage groove 10 is fixedly connected between the two arms 1 and the vertical frames 5 and the pressure rollers 2.
[0025] The waterproof membrane roll 4 is passively unwound, and the entire device is moved by pushing the handle 3. The pressure roller 2 presses the waterproof membrane onto the ground, thereby laying the waterproof membrane. The laying process is carried out by cutting the waterproof membrane with the cutter 9 to remove excess width, and collecting it through the storage groove 10. Cutting can be done at the same time as laying, thus avoiding the problem of mismatched laying width.
[0026] The waterproof membrane roll 4 is threaded onto the mounting shaft 11. The mounting shaft 11 is fixedly mounted with two conical chucks 20 at both ends of the waterproof membrane roll 4 by the second bolts 12. The tail end of the conical chuck 20 and the mounting shaft 11 are provided with round holes for the second bolts 12 to pass through. The end of the second bolts 12 is threaded with a nut. The conical chucks 20 are clamped on the inner cavity of the waterproof membrane roll 4.
[0027] One end of the mounting shaft 11 is hinged to the first rotating seat 13, and the other end of the mounting shaft 11 is fixedly mounted on the second rotating seat 15 by the third bolt 14. The end of the mounting shaft 11 overlaps with the end of the second rotating seat 15 and both have a round hole for the third bolt 14 to pass through. The end of the third bolt 14 is threaded with a nut. Both the second rotating seat 15 and the first rotating seat 13 are rotatably mounted to the boom 1.
[0028] The mounting shaft 11 and the second rotating seat 15 are assembled together. In the disassembled state, the mounting shaft 11 can be tilted relative to the first rotating seat 13, which makes it easier to pass the waterproof membrane roll 4 through the mounting shaft 11 and clamp and fix it with the tapered chuck 20, which facilitates the installation and replacement of the waterproof membrane roll 4.
[0029] Both ends of the tool holder 7 are provided with open clamping slots 16 that are compatible with the crossbar 6. The opening of the open clamping slot 16 is locked by the fourth bolt 17. The tool holder 7 is provided with a round hole for the fourth bolt 17 to pass through at the opening of the open clamping slot 16. The end of the fourth bolt 17 is threaded with a nut. The fourth bolt 17 can lock the two sides of the open clamping slot 16 to form a clamping and fixing effect.
[0030] The fourth bolt 17 is used to lock the opening clamping groove 16 and the crossbar 6 for clamping and fixing. By loosening the fourth bolt 17, the knife holder 7 can move along the crossbar 6 through the opening clamping groove 16, which makes it easy to adjust the cutting position and control the paving width after cutting.
[0031] The cutter holder 7 is provided with a groove 21 that corresponds to and fits the cutter 9. The first bolt 8 passes through both the cutter 9 and the cutter holder 7. Both the cutter 9 and the cutter holder 7 are provided with round holes for the first bolt 8 to pass through. The end of the first bolt 8 is threaded with a nut.
[0032] The cutter 9 is positioned by setting the groove 21, thereby increasing the stability of the installation of the cutter 9 and the cutter holder 7.
[0033] The bottom surface of the boom 1 is fixedly connected to an auxiliary support leg 18 that is inclined to it, and the auxiliary support legs 18 are rotatably connected together by an auxiliary roller 19.
[0034] The auxiliary rollers 19 and auxiliary legs 18 provide auxiliary support for the boom 1, which is supported and facilitates the pushing and moving of the device.
[0035] The working principle of this utility model is as follows:
[0036] In use, the mounting shaft 11 and the second rotating seat 15 are assembled. In the disassembled state, the mounting shaft 11 can be tilted relative to the first rotating seat 13, so that the waterproof membrane roll 4 can be easily threaded onto the mounting shaft 11 and clamped and fixed by the conical chuck 20. At this time, the mounting shaft 11 is reset and fixed to the first rotating seat 13 by the third bolt 14. At this time, the fourth bolt 17 can be loosened so that the knife holder 7 can slide along the crossbar 6, thereby adjusting the position of the cutter 9. Then the fourth bolt 17 is tightened and clamped and fixed to the crossbar 6 through the open clamping groove 16. At this time, the waterproof membrane roll 4 is led out, cut by the cutter 9 and pressed onto the pressure roller 2. It is then pushed by the handle 3 to be laid. The cut waterproof membrane falls into the collection groove 10 and is collected.
