Description

Technical Field

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

[0002] The wet-laying method is a widely used method for installing waterproof membrane rolls. During installation, after preparing the substrate, the adhesive mortar is prepared according to the specified ratio. Once prepared, the mortar is evenly sprayed onto the substrate, and then the waterproof membrane roll is laid. Spraying and laying are done simultaneously, with minimal intervals between applications. In existing methods, workers first apply the mortar with a trowel before laying the waterproof membrane, resulting in long intervals, low efficiency, and difficulty in ensuring the quality of the waterproof membrane roll installation. 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 trolley, which comprises a base frame and a handle. The base frame has downward-facing rollers, and a support frame is located at the front of the base frame. A hopper is mounted on the support frame, and a discharge port is located on the bottom of the hopper. The length of the discharge port is along the width of the base frame. A rotating rod is located at the discharge port and is rotatably connected to the inner walls on both sides of the discharge port via bearings. One end of the rotating rod passes through the hopper and is connected to a motor, which is fixed to the base frame. A support rod is located on the base frame, behind the hopper. A waterproof membrane roll is sleeved on the support rod, and a pressure roller is hinged to the rear of the base frame.

[0006] Preferably, the support frame is a rectangular frame, with the hopper gradually tapering downwards to the discharge port.

[0007] Preferably, the rotating rod is a rotating shaft or an auger screw.

[0008] Preferably, the bottom frame is provided with symmetrical connecting plates at the rear, and both connecting plates are hinged to connecting rods, with the two connecting rods respectively hinged to both ends of the pressure roller.

[0009] Preferably, the support rod passes through both sides of the bottom frame, and nuts are provided at both ends of the support rod.

[0010] The waterproof membrane laying device of the present invention can lay the waterproof membrane while spraying the slurry, which improves the construction efficiency. The hopper discharge port is equipped with a rotating rod to prevent uneven feeding and to prevent the slurry from accumulating at the discharge port. It can evenly spray the adhesive slurry onto the base layer and ensure the construction quality of the waterproof membrane. Attached Figure Description

Detailed Implementation

[0016] 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.

[0017] This embodiment includes a trolley, which comprises a base frame 1 and a handle 2. The base frame 1 has downward-facing rollers 3, and the handle 2 is located at the front end of the trolley, allowing the trolley to be pushed or pulled. A support frame 4 is located at the front of the base frame 1, and a hopper 5 is mounted on the support frame 4. The hopper 5 has an opening at its upper end and is used to hold the slurry. A discharge port 6 is located on the bottom surface of the hopper 5, with its length extending along the width of the base frame 1. The length of the discharge port 6 is slightly less than the width of the base frame 1, but can be equal to the width of the waterproof membrane. In this embodiment, the support frame 4 is a rectangular frame, and the hopper 5 gradually tapers downwards to the discharge port 6, allowing it to be secured to the support frame 4. A rotating rod 7 is provided at the discharge port 6. The rotating rod 7 is rotatably connected to the inner walls on both sides of the discharge port 6 via bearings. The rotating rod 7 can rotate at the discharge port 6. The function of the rotating rod 7 is to prevent the slurry from accumulating or clogging at the discharge port 6. At the same time, the rotation of the rotating rod 7 can also make the slurry drip down evenly. Preferably, the rotating rod 7 is a rotating shaft or an auger screw. In this embodiment, a rotating shaft is used, as shown in the attached figure. Figure 4 As shown. One end of the rotating rod 7 passes through the hopper 5 and is connected to a motor 8. The motor 8 is fixed on the base frame 1, and the rotating rod 7 is driven to rotate by the motor 8.

[0018] A waterproof membrane roll 10 is provided behind the hopper 5. The waterproof membrane roll 10 is sleeved on a support rod 9 and can rotate around the support rod 9. The support rod 9 is located behind the hopper 5, and its two ends pass through both sides of the bottom frame 1. Nuts 14 are provided at both ends of the support rod 9. By tightening the nuts 14, the support rod 9 can be fixed together with the bottom frame 1. By unscrewing the nuts 14, the support rod 9 can be pulled out from the bottom frame 1.

[0019] A pressure roller 11 is hinged to the rear of the bottom frame 1. The pressure roller 11 is used to compact the waterproof membrane. Connecting plates 12 are symmetrically provided at the left and right ends of the bottom frame 1. The two connecting plates 12 are respectively hinged to connecting rods 13. The two connecting rods 13 are respectively hinged to the two ends of the pressure roller 11, and the pressure roller 11 can rotate.

[0020] During construction, slurry is placed in hopper 5, waterproof membrane roll 10 is fitted onto support rod 9, the waterproof membrane is pulled out and placed under pressure roller 11 and the end of the waterproof membrane is pressed down, motor 8 is turned on to rotate rod 7, and at the same time the trolley is slowly pulled forward, the slurry falls onto the base layer from discharge port 6, and then the waterproof membrane is laid on the slurry, and then compacted by pressure roller 11. The spraying of slurry, laying and compaction of waterproof membrane are completed in one go, greatly improving construction efficiency.
