Description

Technical Field

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

[0002] Waterproof membranes play a crucial role in building construction, ensuring the safety, durability, and comfort of buildings. They effectively prevent water penetration, protect the building's structure and internal facilities, and prevent water damage. Traditional manual application of waterproof membranes requires multiple steps and multiple people, making the process complex and prone to errors. While various automated waterproof membrane application devices have emerged, most of these devices carry built-in gas cylinders because the asphalt on the membrane surface needs to be heated with flame during application. The fact that these gas cylinders move with the construction team poses a safety hazard that needs to be addressed. 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 laying device.

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

[0005] A waterproof membrane laying device includes a support plate with a push-pull handle fixed upward at the rear end. A take-up drum is installed on the upper surface of the support plate. Two rolling wheels are symmetrically installed downward on both sides of the bottom rear surface of the support plate, and a front rolling wheel is installed downward on the bottom front surface of the support plate. The width of the front rolling wheel is equal to the width of the waterproof membrane, the distance between the two rolling wheels is less than the width of the waterproof membrane, and the wheel spacing between the two rolling wheels is greater than the width of the waterproof membrane. A main gas pipeline is fixed on the upper front surface of the support plate, and several gas branch pipelines are connected to the main gas pipeline. Each gas branch pipeline is connected to a flame gun. A bracket is fixed on the side front of the support plate, and a horizontal suspension shaft is integrally connected to the bracket. A roll of waterproof membrane is sleeved on the suspension shaft, which is located behind the flame gun. The device also includes a gas canister trolley on which a gas canister is placed. A gas hose is wound around the take-up drum, with one end of the gas hose connected to the gas canister and the other end connected to the main gas pipeline.

[0006] Preferably, both the main gas pipeline and the gas branch pipeline are steel pipes.

[0007] Preferably, the distance between the nozzle of the flame gun and the waterproof membrane is 20-30cm.

[0008] Preferably, the flame gun head has an angle of 30-45° with the horizontal plane.

[0009] The waterproof membrane laying device of this invention separates the gas cylinder from the laying device, so the gas cylinder does not move with the construction, thus improving safety. This invention can simultaneously compact the waterproof membrane and its overlaps, allowing for immediate compaction and better adhesion, improving construction efficiency and ensuring construction quality.

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 support plate 1, with a push-pull handle 2 fixed upward at the rear end of the support plate 1. The push-pull handle 2 is used to push the entire device. A take-up reel 3 is installed on the upper surface of the support plate 1. The take-up reel 3 is rotatable, and a gas hose 12 is wound around the take-up reel 3. The function of the take-up reel 3 is to take up and unwind the gas hose 12. Two rolling wheels 4 are symmetrically installed downwards on both sides of the bottom rear surface of the support plate 1, and a rolling front wheel 5 is installed downwards on the bottom front surface of the support plate 1. The rolling front wheel 5 is used to roll the waterproof membrane, and the rolling rear wheel 4 is used to roll the overlap of the waterproof membrane. At the same time, it can roll the edges of the waterproof membrane a second time. Therefore, the width of the rolling front wheel 5 is equal to the width of the waterproof membrane. The distance between the two rolling rear wheels 4 is less than the width of the waterproof membrane. That is, there is a gap between the two rolling rear wheels 4 and they are not connected. The wheel distance between the two rolling rear wheels 4 is greater than the width of the waterproof membrane. The wheel distance mentioned here refers to the distance between the center lines of the two rolling rear wheels 4. In this way, the rolling rear wheels 4 can press the overlap of the waterproof membrane.

[0015] A main gas pipe 6 is fixed to the upper front surface of the support plate 1. Several branch gas pipes 7 are connected to the main gas pipe 6. In this embodiment, three branch gas pipes 7 are connected to the two sides and the middle. Each branch gas pipe 7 is connected to a flame gun 8. Both the main gas pipe 6 and the branch gas pipes 7 are made of steel pipes. The flame gun 8 is located in front of the waterproof membrane, and its position corresponds to the waterproof membrane. The flame gun 8 is used to spray and heat the waterproof membrane. Preferably, the distance between the nozzle of the flame gun 8 and the waterproof membrane is 20-30cm, and the angle between the nozzle of the flame gun 8 and the horizontal plane is 30-45°.

[0016] A bracket 9 is fixed to the front side of the support plate 1. A horizontal suspension shaft 10 is integrally connected to the bracket 9. The suspension shaft 10 is located behind the flame gun 8. The suspension shaft 10 is used to attach the rolled waterproof membrane. The waterproof membrane can rotate around the suspension shaft 10 when it is hung on the suspension shaft 10.

[0017] This embodiment also includes a gas cylinder trolley 11. The gas cylinder is not placed on the support plate 1, but on the gas cylinder trolley 11. The gas cylinder trolley 11 can be any existing trolley used for transporting gas cylinders. A gas hose 12 is wound around the take-up reel 3. One end of the gas hose 12 is connected to the gas cylinder, and the other end of the gas hose 12 is connected to the main gas pipeline 6.

[0018] During construction, the rolled waterproof membrane is first hung on the suspension shaft 10. Then, the membrane is moved forward past the front roller 5 and placed below it. The flame torch 8 is then turned on to heat the asphalt surface of the membrane. The device is slowly pushed forward, and the heated membrane is laid on the ground substrate. The front roller 5 then presses the membrane, followed by the rear roller 4, causing asphalt to overflow at the overlap. This process compacts both the membrane and the overlap, eliminating the need for separate compaction of the overlap and allowing for immediate shaping and better adhesion. During the forward movement of the device, the gas cylinder cart 11 remains stationary. As the distance between the gas cylinder cart 11 and the device increases, the take-up reel 3 rotates to release the gas hose 12 to accommodate the distance change. Once the gas hose 12 released by the take-up reel 3 reaches a certain length, the gas cylinder cart 11 can be pushed to the construction point, and the take-up reel 3 can be rotated to rewind the gas hose 12 before continuing construction.

[0019] 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.
