Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to an auxiliary device for laying waterproof membrane. Background Technology

[0002] Waterproof membranes are mainly used in building walls, roofs, tunnels, highways, landfills, etc., to resist external rainwater and groundwater seepage. They are flexible building materials that can be rolled up and serve as a leak-proof connection between the foundation and the building. They are the first line of defense for waterproofing the entire project and play a vital role in the overall project.

[0003] In related technologies, the installation of waterproof membranes typically involves workers unwinding the membrane while simultaneously heating it with a handheld spray gun and then attaching it to the roof.

[0004] However, the process of workers heating the waterproof membrane with handheld spray guns has a low degree of automation, which affects construction efficiency. In addition, the heavy spray guns also increase the burden on workers, which needs to be improved. Utility Model Content

The two support blocks are respectively horizontally rotatably connected to a limiting part for pressing against the waterproof membrane on their respective sides, and the handcart is provided with a driving member for controlling the two support blocks to move closer or further apart.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Reference Figure 1 , Figure 2 A waterproof membrane auxiliary laying device includes a handcart 1, on which an unwinding mechanism 2 is provided. The unwinding mechanism 2 is used to unwind the waterproof membrane, with the waterproof membrane facing forward of the handcart 1 and the adhesive side of the waterproof membrane facing upward.

[0028] Reference Figure 1 , Figure 3 A support tube 3 is horizontally fixedly connected to the front end of the handcart 1. The length direction of the support tube 3 is perpendicular to the forward direction of the handcart 1, and both ends of the support tube 3 are sealed. Multiple flame nozzles 4 are fixedly connected to the lower end of the support tube 3. The multiple flame nozzles 4 are arranged at equal intervals along the length direction of the support tube 3, and the waterproof membrane can pass under the multiple flame nozzles 4 so that the multiple flame nozzles 4 can heat the bonding surface of the waterproof membrane together.

[0029] Reference Figure 1 , Figure 3 The waterproof membrane auxiliary laying device also includes a gas cylinder 5 and an air inlet pipe 6. The gas cylinder 5 is detachably connected to the handcart 1. One end of the air inlet pipe 6 is connected to the nozzle of the gas cylinder 5 through a quick connector, and the other end is fixedly connected to the support pipe 3. At the same time, an adjustment valve 7 is connected to the air inlet pipe 6.

[0030] When laying the waterproof membrane, the regulating valve 7 is opened, and multiple burner nozzles 4 are ignited. The air supply is then adjusted through the regulating valve 7 to regulate the flame size of the burner nozzles 4. Subsequently, the waterproof membrane is unwound by the unwinding mechanism 2, with the bonding surface of the membrane passing under the burner nozzles 4. At this time, multiple burner nozzles 4 heat the bonding surface of the waterproof membrane together. Simultaneously, the handcart 1 is pushed forward to bond the waterproof membrane to the roof. The membrane is then compacted, completing the laying process. This design enables automatic heating during the waterproof membrane laying process, reducing the workload of workers and improving construction efficiency.

[0031] Reference Figure 1 , Figure 2 The front end of the handcart 1 is rotatably connected to a tension roller 8, which is located below the front side of the support tube 3. The waterproof membrane can be wrapped around the tension roller 8 to ensure the tension effect of the waterproof membrane, reduce the risk of wrinkles in the waterproof membrane, and ensure the adhesion between the waterproof membrane and the roof.

[0032] Reference Figure 1 , Figure 3 A support frame 9 is fixedly connected to the handcart 1. The support frame 9 is provided with a limiting groove 10 for the gas cylinder 5 to be tightly inserted, thereby limiting the horizontal direction of the gas cylinder 5. At the same time, the support frame 9 is provided with a limiting strap 11 for binding and fixing the gas cylinder 5 to ensure the fixing effect of the gas cylinder 5.

[0033] Reference Figure 1 , Figure 3 The unwinding mechanism 2 includes two vertically arranged support blocks 21, which are horizontally slidably connected to the handcart 1. The sliding direction of the support blocks 21 is perpendicular to the forward direction of the handcart 1. The handcart 1 is equipped with a drive member 23 for controlling the two support blocks 21 to move closer or further apart. At the same time, the sides of the two support blocks 21 that are close to each other are horizontally rotatably connected to limiting parts 24, which are used to press against the waterproof membrane, thereby fixing the waterproof membrane.

[0034] After the waterproof membrane is bonded to the roof, pushing the trolley 1 forward will cause the waterproof membrane to rotate the limiting part 24, thereby realizing the automatic unwinding of the waterproof membrane and ensuring the tension effect of the waterproof membrane, thus improving the laying effect of the waterproof membrane.

[0035] Reference Figure 1 , Figure 3Each limiting part 24 includes a horizontally arranged rotating shaft 241 and a limiting post 242. One end of the rotating shaft 241 is rotatably connected to the corresponding support block 21, and the other end is coaxially fixedly connected to the corresponding limiting post 242. A conical limiting surface 243 is provided on the side of the limiting post 242 away from the corresponding rotating shaft 241. The limiting post 242 is used to insert into the roll of waterproof membrane, and the limiting surface 243 is interference-fitted with the inner wall of the roll of waterproof membrane to achieve rapid fixation of the waterproof membrane.

[0036] Reference Figure 1 , Figure 3 The driving component 23 includes a reversible motor 231 and a dual-drive screw 232. The reversible motor 231 is fixed to the handcart 1. Both ends of the dual-drive screw 232 pass through corresponding support blocks 21 and are rotatably connected to them. Simultaneously, one end of the dual-drive screw 232 is coaxially and fixedly connected to the output shaft of the reversible motor 231, and the other end is rotatably connected to the handcart 1. By controlling the rotation of the dual-drive screw 232 through the reversible motor 231, the dual-drive screw 232 can control the two support blocks 21 to move closer or further apart, which is beneficial for replacing the waterproof membrane.
