Description

Technical Field

[0001] This utility model relates to the field of building waterproofing engineering technology, specifically a waterproofing membrane laying device for building waterproofing engineering. Background Technology

[0002] Waterproof membrane is a widely used waterproof material in the construction industry, especially suitable for areas prone to water erosion such as roofs, basements, and bathrooms. Among them, self-adhesive waterproof membrane is widely used due to its convenient construction and excellent waterproof performance. Self-adhesive waterproof membrane has a self-adhesive layer, which can be directly bonded to the substrate during laying. It is also highly adaptable to the substrate. When laying self-adhesive waterproof membrane, simply lay the membrane flat on the substrate and then gently press it down. No additional hot pressing equipment or process is required.

[0003] However, when laying self-adhesive waterproof membrane, it is usually done manually. At least two workers are needed to carry the waterproof membrane, remove the release paper, and manually press the waterproof membrane down. The amount of manual labor is large, resulting in low work efficiency. Utility Model Content

[0030] 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.

[0031] Example

[0032] Please see Figure 1-5 In this embodiment of the utility model, a waterproof membrane installation device for building waterproofing projects includes a mobile trolley 100, side frames 200, a guiding mechanism 300, and a first leveling mechanism 400. A push rod 110 is fixedly connected to the top surface of the mobile trolley 100, allowing workers to pull or lift the device. Two side frames 200 are fixedly connected to the top surface of the mobile trolley 100, and an installation roller 210 is rotatably connected between the top ends of the two side frames 200. The outer wall of the installation roller 210 is used to fit the waterproof membrane body 700. A guiding mechanism 300 is provided at the front end of the top surface of the mobile trolley 100. The guiding mechanism 300 includes a first guide roller 310, a second guide roller 320, and two support frames 330. The bottom ends of both support frames 330 are fixedly connected to the top surface of the mobile trolley 100, and a first connecting block 340 is fixedly connected to the top end of each of the two support frames 330. The bottom surfaces of both first connecting blocks 340 are provided with... The two ends of the connecting block 350 and the guide roller 310 are rotatably connected to the side walls of the two connecting blocks 340 respectively. The two ends of the guide roller 320 are rotatably connected to the side walls of the two connecting blocks 350 respectively. A motor 360 is fixedly connected to the outer side wall of one of the connecting blocks 350. The motor shaft of the motor 360 passes through the side wall of the connecting block 350 and is connected to one end of the guide roller 320. A first leveling mechanism 400 is provided on the front end of the moving trolley 100. The first leveling mechanism 400 includes a top frame 410. Two electric telescopic rods 420 are fixedly connected to the bottom surface of the top frame 410. A fixed plate 430 is fixedly connected to the output end of the two electric telescopic rods 420. A scraper 440 is fixedly connected to the bottom surface of the fixed plate 430. Two connecting rods 450 are fixedly connected to the side wall of the top frame 410. The other ends of the two connecting rods 450 are fixedly connected to the side walls of the two support frames 330 respectively.

[0033] Specifically, during installation, the paper tube of the rolled waterproof membrane body 700 is placed over the outer wall of the installation roller 210. The end of the waterproof membrane body 700 is pulled out and passed between the guide roller 1 310 and the guide roller 2 320, then passed under the scraper 1 440 and attached to the installation position. A section of the release paper on the bottom surface of the waterproof membrane body 700 is torn off and wound around the outer wall of the guide roller 2 320. The two electric telescopic rods 1 420 are extended to make the bottom of the scraper 1 440 tightly adhere to the surface of the waterproof membrane body 700, ensuring that the waterproof membrane body 700 is in close contact with the ground. The system controls the moving trolley 100 to travel in a straight line, while simultaneously starting motor 360 to drive guide roller 320 to rotate. This causes the torn release paper to wrap around the outer wall of guide roller 320. Guide rollers 310 and 320 are in contact with both sides of the waterproof membrane body 700, ensuring that the waterproof membrane body 700 is flat and wrinkle-free. During the movement, scraper 440 maintains close contact with the waterproof membrane body 700, scraping and driving the waterproof membrane body 700 forward to ensure the flatness of the waterproof membrane during the laying process.

[0034] like Figure 3 As shown, in this embodiment, the bottom surfaces of the two connecting blocks 340 are provided with sliding grooves 341, and the top surfaces of the two connecting blocks 350 are fixedly connected with round rods 351. The two round rods 351 are slidably connected to the two sliding grooves 341 respectively, and the outer walls of the two round rods 351 located inside the sliding grooves 341 are fitted with return springs 352.

[0035] In this embodiment, due to the elastic extension and contraction characteristics of the reset spring 352, the top surface of the second connecting block 350 is in close contact with the bottom surface of the first connecting block 340 when there is no external force. As the laying progresses, the outer wall of the second guide roller 320 gradually accumulates the thickness of the release paper, causing the second connecting block 350 to drive the second guide roller 320 to move downward. The reset spring 352 contracts, so that the second guide roller 320 and the first guide roller 310 always maintain an appropriate distance, ensuring that the flatness of the waterproof membrane body 700 is not affected.

[0036] like Figure 2 and Figure 4As shown, in this embodiment, a second leveling mechanism 500 is fixedly connected to the bottom surface of the top frame 410. The second leveling mechanism 500 includes two electric telescopic rods 510. The top ends of the two electric telescopic rods 510 are fixedly connected to the bottom surface of the top frame 410. A rectangular strip 520 is fixedly connected to the output end of the two electric telescopic rods 510. A strip groove is opened on the bottom surface of the rectangular strip 520. A lead screw 530 is rotatably connected in the strip groove. A separator ring is sleeved and fixed at the center position on the outer wall of the lead screw 530. The threads at the left and right ends rotate in opposite directions. The outer walls of the lead screw 530 are symmetrically connected to two moving blocks 550. The bottom surfaces of the two moving blocks 550 are fixedly connected to connecting plates 560. The bottom surfaces of the two connecting plates 560 are fixedly connected to scraper 2 570. The end side of the rectangular bar 520 is fixedly connected to motor 2 540. The motor shaft of motor 2 540 is connected to one end of the lead screw 530. The outer walls of scraper 2 570 and scraper 1 440 are provided with flexible pads to avoid wear on the waterproof membrane body 700.

[0037] In practice, after the mobile trolley 100 lays the waterproof membrane body 700 along a straight line, the waterproof membrane body 700 is cut off. Then, the two electric telescopic rods 420 are retracted, causing the scraper 440 to move upward. The mobile trolley 100 is then controlled to travel in the opposite direction to the starting point. During this process, if air bubbles are encountered, the motor 540 is started to drive the lead screw 530 to rotate. Through threaded engagement, the two moving blocks 550 move towards each other. Then, the electric telescopic rod 510 is extended, so that the bottom ends of the two scrapers 570 are in contact with the surface of the laid waterproof membrane body 700. The motor 540 is then started to drive the lead screw 530 to rotate in the opposite direction, causing the two moving blocks 550 to move away from each other, thereby expelling the air bubbles.

[0038] like Figure 2 and Figure 5 As shown, in this embodiment, a compaction mechanism 600 is fixedly connected to the side wall of the mobile trolley 100 away from the first leveling mechanism 400. The compaction mechanism 600 includes two mounting plates 610. The side walls of the two mounting plates 610 are fixedly connected to the side wall of the mobile trolley 100. Support plates 620 are fixedly connected to the outer walls of the two mounting plates 610. Electric telescopic rods 630 are fixedly connected to the bottom surfaces of the two support plates 620. Fixed frames 640 are fixedly connected to the output ends of the two electric telescopic rods 630. Pressure rollers 650 are rotatably connected between the two inner side walls of the fixed frame 640.

[0039] In practice, after the mobile trolley 100 has laid a waterproof membrane body 700 along a straight line, the mobile trolley 100 is controlled to travel in the opposite direction to the starting point, and the two electric telescopic rods 630 are controlled to extend, so that the surface of the pressure roller 650 is in close contact with the surface of the waterproof membrane body 700. As the mobile trolley 100 moves, the pressure roller 650 compacts the waterproof membrane body 700 after the air bubbles are expelled.
