Description

Technical Field

[0001] The invention relates to the technical field of waterproof coiled material paving, and in particular to a waterproof coiled material paving device. Background Art

[0002] Waterproofing membranes are mainly used in building walls, roofs, tunnels, roads, landfills, etc. They are a kind of flexible building material products that can be rolled into a roll to prevent the leakage of rainwater and groundwater from the outside. As a non-leakage connection layer between the engineering foundation and the building, it is the first barrier for waterproofing the entire project and plays a vital role in the entire project. The main products are asphalt waterproofing membranes and polymer waterproofing membranes.

[0003] Depending on the material, there are two main construction methods for waterproofing membranes: hot melt and cold adhesive. When using the hot melt method, one person is required to spread the waterproofing membrane, one to heat and bake it, one to lay it, and one to use a pressure wheel to remove bubbles; the workers have high labor intensity and are easily burned; at the same time, when the waterproofing membrane is manually melted by flame spraying, the melting time is long, and because the distance between the torch flame and the waterproofing membrane is difficult to control, the flame spraying and melting within the width of the waterproofing membrane is uneven, the temperature is too low, resulting in poor bonding between the waterproofing membrane and the base surface, and the temperature is too high, it is easy to melt through the membrane.

[0004] The existing Chinese invention patent with announcement number CN109610322B discloses an asphalt waterproofing membrane paving equipment and paving method. The equipment includes a rolling steel roller, a traction device, a spray melting device and a paving trolley arranged in sequence along the paving direction of the waterproofing membrane. The traction device includes a reel and two traction rods, one end of the traction rod is rotatably connected to the reel, and the other end of the traction rod is rotatably connected to the paving trolley; the spray melting device includes a plurality of main blowtorches and a plurality of auxiliary blowtorches, and the spraying direction of the main blowtorch is always the radial direction of the waterproofing membrane; the spraying point of the auxiliary blowtorch is close to the junction of the waterproofing membrane and the base surface so that the base surface can be preheated before bonding with the waterproofing membrane.

[0005] Although the above-mentioned waterproofing coiled material paving equipment can meet the laying requirements of the coiled material to a certain extent, it has obvious limitations. It only focuses on laying the waterproofing coiled material on the surface of the base layer, while ignoring the crucial process of hot-melt edge sealing. In actual construction, hot-melt edge sealing plays an irreplaceable role in ensuring the integrity and durability of the waterproofing effect. However, due to the lack of existing inventions and technologies, construction personnel usually need to use separate tools and methods to perform hot-melt edge sealing operations after the coiled material is laid. A common situation is to use a handheld flame spray gun to heat and seal the edges of the coiled material. This method is not only inefficient, but the quality of the edge sealing depends largely on the experience and operating skills of the construction personnel. Due to the uncertainty of manual operation, it is easy to have uneven, discontinuous, or even partially unsealed edge sealing problems, which bury the hidden danger of leakage for waterproofing projects. In addition, the separate edge sealing operation also increases the complexity and time cost of construction and reduces the overall construction efficiency. Moreover, due to the uneven operating levels of different construction personnel, it is difficult to ensure the consistency and stability of the edge sealing effect. Summary of the invention

[0006] The purpose of the present invention is to provide a waterproof coiled material paving device, which can perform hot-melt edge sealing while the waterproof coiled material is being paved, thereby ensuring that the edges of the coiled material are tightly sealed, improving construction efficiency, and ensuring the stability of the quality of the waterproof project.

[0024] A first bidirectional screw 14 is rotatably disposed between the two side connecting plates 10 , and the two mounting plates 12 are respectively threadedly connected to two ends of the first bidirectional screw 14 .

[0025] A pressing cylinder 15 is installed at the bottom of the mounting plate 12 , and the pressing cylinder 15 is arranged opposite to the edge-sealing blowtorch 13 .

[0026] A sleeve 16 is fixedly connected to the bottom of the mounting plate 12 , a telescopic rod 17 is slidably connected inside the sleeve 16 , a spring is connected between the top of the telescopic rod 17 and the sleeve 16 , and the bottom of the telescopic rod 17 is fixedly connected to the pressing tube 15 .

[0027] A sliding rod 18 is fixedly connected between the two connecting plates 2, and two slide plates 19 are slidably sleeved on the sliding rod 18. A second bidirectional screw 20 is rotatably arranged between the two connecting plates 2. The two slide plates 19 are respectively threadedly connected to the two ends of the second bidirectional screw 20. The slide plates 19 are fixedly connected to a limiting plate 21 close to the coil winding drum 3.

[0028] The limiting plate 21 is in an arc-shaped structure.

[0029] A push-pull handle 22 is provided at the rear end of the paving trolley 1 .

[0030] The paving trolley 1 is provided with a gas supply bottle, and the air inlet pipe 7 is connected to the gas supply bottle through an air delivery pipe.

[0031] Working principle:

[0032] The waterproofing coiled material is wound on the coiled material winding drum 3, and the second bidirectional screw 20 is rotated to drive the two slide plates 19 to move, and the spacing between the limiting plates 21 is adjusted. The two sides of the waterproofing coiled material are limited by the limiting plates 21 to prevent the waterproofing coiled material from moving along the coiled material winding drum 3 during the unwinding process; the first bidirectional screw 14 is rotated to drive the two mounting plates 12 to move, so that the edge sealing blowtorch 13 and the pressing cylinder 15 are arranged directly opposite to the edge of the waterproofing coiled material;

[0033] The surface of the waterproof coiled material is sprayed and melted by the main blowtorch 8, and the waterproof coiled material is bonded to the base surface after melting. The waterproof coiled material is laid on the base by pushing the paving trolley 1 and the coiled material winding drum 3 to rotate, and then the laid waterproof coiled material is compacted by the rolling drum 9 to discharge the air therein, so that the waterproof coiled material is firmly bonded;

[0034] As the paving trolley 1 moves forward, the edge sealing blowtorches 13 on both sides heat-melt the joints on the edges of the laid waterproof membrane, so that the waterproof membrane melts and overflows the modified asphalt glue, and then tightly combines with the base layer to achieve edge sealing; the overflowed modified asphalt glue is compacted by the pressing cylinder 15, so that the edge sealing is tighter and the overflowed modified asphalt glue is more evenly distributed.

[0035] The present invention can perform hot-melt edge sealing while the waterproof coiled material is being laid, ensuring that the edges of the coiled material are tightly sealed, effectively preventing moisture from seeping in from the edges, and greatly improving the overall quality and reliability of the waterproof project; the integrated operation avoids the tedious steps of performing edge sealing separately, saves construction time, reduces waiting and connection time between processes, and improves construction efficiency; eliminates the problem of unstable edge sealing quality caused by differences in experience and skills during manual edge sealing, so that each edge sealing can meet the standards of uniformity, continuity and tightness, ensuring the stability of the quality of the waterproof project.
