[0002] In the construction process of basement structure, a common practice is to first use mechanical equipment to excavate the foundation pit, and then start the construction of the main structure of the basement; after the main structure of the basement is completed, it enters the stage of external wall waterproofing, which is a key step to ensure that the basement is not eroded by external moisture. External wall waterproofing usually includes two main measures: applying waterproof coating and laying waterproof membrane.

DETAILED DESCRIPTION

[0020] Example 1 This embodiment provides a double-head waterproofing coiled material 10, with overlapping parts on both sides of the edges. Each overlapping part has an upper and lower layer structure; an overlapping area is provided in the overlapping part, and the overlapping area is composed of the area between the upper and lower layer structures.

[0021] When overlapping, adjacent double-ended waterproof membranes 10 are connected in a predetermined direction by gluing. Figure 1 As shown, the first double-head waterproof membrane ( Figure 1 The upper structure 11 of the double-headed waterproof membrane 10 on the right side of the middle is pasted on the second double-headed waterproof membrane ( Figure 1 In the corresponding side overlap area of ​​the double-headed waterproof membrane 10 on the left side, the lower structure 12 of the second double-headed waterproof membrane is pasted on the corresponding side overlap area of ​​the first double-headed waterproof membrane.

[0022] The above-mentioned double-head waterproof coiled material 10 includes a base material layer, a waterproof coating, a reinforcing fiber mesh layer, and an adhesive layer. The base material layer is made of a high molecular polymer material, has high strength, high elongation and good anti-aging performance, and serves as the main structure of the waterproof coiled material to provide basic physical strength and durability. The waterproof coating is tightly coated on both sides of the base material layer, and is composed of a synthetic resin or rubber material with excellent water resistance. The waterproof coating contains a microporous structure or a cross-linked network structure to effectively prevent water penetration, while maintaining a certain air permeability to prevent internal water vapor accumulation. The reinforcing fiber mesh layer is embedded between the base material layer and the waterproof coating, and is woven from high-strength fibers such as polyester fibers, glass fibers or aramid fibers, and is used to enhance the tensile strength and dimensional stability of the entire coiled material, ensuring long-term reliability under complex stress conditions.

[0023] The adhesive layer is arranged on the overlapped part, specifically on both sides of the upper structure 11 and the lower structure 12. The adhesive layer is composed of asphalt, polymer modified asphalt, etc. The adhesive layer is heated and melted to achieve the adhesion of the overlapped parts of the adjacent double-headed waterproof membranes 10.

[0024] In the above technical solution, the upper structure 11 and the lower structure 12 of the overlapping parts of adjacent double-headed waterproof membranes 10 are pasted to each other to increase the pasting area of ​​the overlapping parts, so that the bonding between adjacent double-headed waterproof membranes 10 is tighter; this tight bonding helps to enhance the bonding strength and improve the overall stability of the double-headed waterproof membrane 10; when subjected to external force, the adjacent double-headed waterproof membranes 10 are less likely to fall off or loosen, thereby ensuring the durability of the waterproof or protective effect.

[0025] Example 2 This embodiment provides a splicing device for splicing a double-headed waterproofing membrane 10 as described in Embodiment 1, comprising: a moving mechanism 20, a liftable unwinding mechanism 30, a bidirectional motion mechanism 40, a heating mechanism 50, and at least two sets of clamping mechanisms 60.

[0026] like Figure 2 As shown, the moving mechanism 20 is an automatic moving vehicle. The moving mechanism 20 includes a frame 21 with a hollow structure, and moving members 22 installed on both sides of the frame 21. The moving member 22 is a moving wheel.

[0027] The retractable unwinding mechanism 30 is assembled at the front end of the frame 21 along the traveling direction and is located in the hollow structure. The unwinding mechanism 30 is configured to unwind the double-headed waterproofing roll 10. The double-headed waterproofing roll 10 is unwound from the hollow structure.

[0028] The bidirectional motion mechanism 40 is installed at the rear end of the frame 21 along the travel direction. The bidirectional motion mechanism 40 is used to achieve movement in two directions. Figure 2 As shown, a linear motion module is used for implementation, which is a prior art and will not be described in detail here.

[0029] The heating mechanism 50 is in transmission connection with the bidirectional motion mechanism 40. The heating mechanism 50 comprises: a first lifting assembly 51, and a heating assembly 52 arranged at the output end of the first lifting assembly 51. That is, under the action of the first lifting assembly 51 and the bidirectional motion mechanism 40, the heating assembly 52 can realize movement in three directions, and the directions in the three directions are perpendicular to each other. The first lifting assembly 51 can be realized by a cylinder or the like.

[0030] At least two sets of pressing mechanisms 60 are correspondingly arranged on both sides of the heating mechanism 50 and are transmission-connected to the bidirectional motion mechanism 40 .

[0031] In the above technical solution, the height of the unwinding mechanism 30 is first adjusted, and the moving mechanism 20 is controlled to lay the first double-headed waterproofing membrane on the ground according to the laying requirements. This automated process can significantly improve the laying efficiency and accuracy, reduce manual labor intensity, and improve the overall construction quality and progress.

[0032] Then, when laying the second double-headed waterproof membrane, the upper structure 11 in the overlapping part of the first double-headed waterproof membrane is opened; the walking mechanism is arranged to contact the surface of the first double-headed waterproof membrane, and the unwinding mechanism 30 is arranged to unwind the second double-headed waterproof membrane along the advancing direction, and the lower structure 12 of the second double-headed waterproof membrane is stacked with the lower structure 12 of the first double-headed waterproof membrane; the walking mechanism limits the first double-headed waterproof membrane, so that the first double-headed waterproof membrane is not easy to shift during the subsequent laying process, thereby ensuring the accuracy and consistency of the laying; it facilitates the alignment of the second double-headed waterproof membrane and the first membrane that are unwound subsequently, and reduces the laying problems caused by the misalignment of the membranes.

[0033] Finally, while the second double-ended waterproofing membrane is unrolled, the first double-ended waterproofing membrane and the second double-ended waterproofing membrane are overlapped by using the pressing mechanism 60 and the heating assembly 52 .

[0034] In a further embodiment, the unwinding mechanism 30 includes: two groups of installation frames 31 , the same number of lifting members 32 as the installation frames 31 , two groups of power members 33 , and a rotatable unwinding roller 34 .

[0035] like Figure 3 As shown, two sets of mounting frames 31 are respectively arranged on both sides of the frame 21. Each lifting member 32 is installed in each mounting frame 31. The lifting member 32 is slidably connected to the inner wall of the mounting frame 31. The lifting member 32 is a lifting column. A stopper 321 is provided at the bottom of the lifting member 32, and the stopper 321 is used to limit the lifting member 32 to prevent it from being separated from the mounting frame 31.

[0036] The output end of each group of power members 33 is connected to the lifting member 32. The power member 33 is configured to drive the lifting member 32 to rise and fall. The power member 33 is a cylinder or the like. The end of the unwinding roller 34 is rotatably connected to the lifting member 32. The unwinding roller 34 is driven to rotate by a motor.

[0037] In the above technical solution, when the walking mechanism is moving, the unwinding roller 34 rotates to unwind the double-headed waterproofing coiled material 10. The height of the unwinding roller 34 is adjusted by the lifting and lowering of the lifting member 32: when unwinding, the unwinding roller 34 is close to the ground, which facilitates the double-headed waterproofing coiled material 10 to be directly laid on the ground; when unwinding is finished, the unwinding roller 34 is away from the ground, which is convenient for transportation.

[0038] That is to say, when unwinding, the unwinding roller 34 is adjusted to a position close to the ground, so that the double-headed waterproofing coil 10 can be laid directly and smoothly on the ground, reducing the intermediate links and transfer steps, thereby improving the laying efficiency. When the unwinding roller 34 is close to the ground, the friction and drag force on the coil during the laying process are reduced, thereby reducing the risk of damage and scratches to the coil, and ensuring the quality and integrity of the coil. The precise adjustment of the lifting member 32 ensures the height stability of the unwinding roller 34, thereby ensuring the stability and flatness of the coil during the laying process. The design of the lifting member 32 allows the height of the unwinding roller 34 to be adjusted according to actual needs, thereby adapting to different heights, different terrains and different laying requirements, and improving the flexibility and adaptability of the equipment.

[0039] In a further embodiment, the heating assembly 52 includes: a first rotating base 521 and a heating element 522. The first rotating base 521 is connected to the first lifting assembly 51, and the first rotating base 521 is an electric rotating base. The heating element 522 is connected to the first rotating base 521. The heating element 522 is configured to heat the overlapped portion. The heating element 522 is electrically heated, and the heating element 522 has a flat heating surface, which is used to heat the overlapped portion so that the adhesive layer on the overlapped portion melts and the adjacent double-headed waterproof membranes 10 are adhered together.

[0040] In the above technical solution, the position and angle of the heating element 522 are first adjusted by using the bidirectional motion mechanism 40, the first lifting assembly 51, and the first rotating base 521, so that it contacts the upper surface of the lower structure 12 of the second double-headed waterproof membrane; and by using the movement of the walking mechanism, the heating element 522 heats the lower structure 12 of the second double-headed waterproof membrane that is unwound in sequence along the laying path, and the adhesive layer of the lower structure 12 of the second double-headed waterproof membrane melts and is pasted together with the lower structure 12 of the first double-headed waterproof membrane to complete the preliminary overlap.

[0041] By adjusting the position and angle of the heating element 522, it is ensured that the heating element 522 is in close contact with the upper surface of the lower structure 12 of the second double-headed waterproofing membrane, thereby achieving precise heating. This helps to avoid the problems of heat loss and uneven heating, and improves heating efficiency and quality. The position and angle of the heating element 522 are adjustable, so that it can adapt to double-headed waterproofing membranes 10 of different widths, thicknesses and shapes, as well as different laying paths and terrain conditions. This flexibility helps to expand the scope of application of the equipment and improve the utilization rate of the equipment.

[0042] The movement of the walking mechanism and the heating process of the heating element 522 are carried out simultaneously, so that the laying and overlapping of the double-headed waterproofing coiled material 10 can be carried out continuously without interruption. This greatly improves the construction efficiency and shortens the construction period. The overlapping method while moving helps to ensure that the overlapping between the double-headed waterproofing coiled materials 10 is tight and uniform, avoiding water leakage caused by poor overlapping. At the same time, the precise heating of the heating element 522 also helps to improve the bonding strength between the coiled materials and ensure the construction quality.

[0043] In a further embodiment, the clamping mechanism 60 includes: a second lifting assembly 61 that is transmission-connected to the bidirectional motion mechanism 40, and a clamping assembly 62 that is disposed at the output end of the second lifting assembly 61. That is, under the action of the second lifting assembly 61 and the bidirectional motion mechanism 40, the clamping assembly 62 can realize movement in three directions, and the directions in the three directions are perpendicular to each other. The second lifting assembly 61 can be realized by a cylinder or the like.

[0044] like Figure 4 and Figure 5 As shown, the pressing assembly 62 includes: a second rotating base 621, a mounting base 622, a frame 623, and a pressing member 624. The second rotating base 621 is connected to the second lifting assembly 61. The second rotating base 621 is an electric rotating base. The mounting base 622 is connected to the second rotating base 621. The frame 623 is installed on the mounting base 622. An accommodating space is set in the frame 623. The pressing member 624 is installed in the accommodating space and is rotatably connected to the frame 623. The pressing member 624 is a roller.

[0045] In the above technical solution, the position and angle of the pressing member 624 are first adjusted by using the bidirectional motion mechanism 40, the second lifting assembly 61, and the second rotating base 621, so that there is pressure between the pressing member 624 and the upper surface of the lower structure 12 of the second double-headed waterproofing membrane; the pressing member 624 rolls forward under the drive of the traveling mechanism. The pressing members 624 arranged on both sides of the heating member 522 press the first double-headed waterproofing membrane and the second double-headed waterproofing membrane.

[0046] The pressing piece 624 fits the first double-headed waterproofing coiled material and the second double-headed waterproofing coiled material tightly together, reducing the air gap between them. The two pressing pieces 624 respectively press the unmelted and melted coiled materials, so that the system can more accurately control the processing status of the coiled materials at different stages. For the unmelted coiled materials, the pressing piece 624 can ensure that it fits the heating element tightly, thereby improving the heat transfer efficiency. For the melted coiled materials, after the coiled materials are melted, the pressing piece 624 can ensure that the melted adhesive layer is evenly distributed between the coils, thereby enhancing the bonding quality and strength and improving the overall performance of the waterproof layer. The rolling forward of the pressing piece 624 ensures the flatness and stability of the coiled materials during the laying process. It avoids the problem of poor overlap or water leakage caused by the movement or deformation of the coiled materials during the heating process.

[0047] In a further embodiment, Figure 6 As shown, the overlapping device further includes two sets of guiding mechanisms 70. The two sets of guiding mechanisms 70 are respectively installed on both sides of the unwinding mechanism 30. The guiding mechanisms 70 are arranged to guide the double-headed waterproofing membrane 10 when the double-headed waterproofing membrane 10 is unrolled.

[0048] like Figure 7 As shown, the guide mechanism 70 includes: a base plate 71, a bracket 72, a first guide roller 73, a second guide roller 74, and a third guide roller 75. The base plate 71 is fixedly mounted on the frame 21. The bracket 72 is provided on the base plate 71. The first guide roller 73 and the second guide roller 74 are arranged in parallel and rotatably connected to the bracket 72. The upper outer surfaces of the first guide roller 73 and the second guide roller 74 together constitute a guide surface. The third guide roller 75 is arranged above the guide surface. There is a gap between the third guide roller 75 and the guide surface. The gap is provided to accommodate the lower structure 12 in the double-headed waterproof membrane 10.

[0049] In the above technical solution, when the second double-headed waterproofing coil is unrolled, the lower structure 12 in the overlapped part on both sides thereof is placed in the above gap to separate the upper structure 11 and the lower structure 12 in the overlapped part, so as to facilitate the stacking of the lower structure 12 of the second double-headed waterproofing coil with the lower structure 12 of the first double-headed waterproofing coil, and facilitate the subsequent pressurization of the heating element 522 and the pressing of the pressing element 624. The above process separates the upper and lower structures 12 of the overlapped part through the first guide roller 73, the second guide roller 74, and the third guide roller 75, and quickly and accurately completes the stacking and preparation of the coil, providing convenience for the subsequent heating and pressing steps; and instead of manual labor, the automated processing can greatly improve production efficiency and reduce the time and labor required for manual operation.

[0050] In addition, since the pressing member 624 is subsequently provided, the pressing member 624 presses and positions the lower structure 12 of the second double-headed waterproofing membrane that has been laid on the ground, and the pressing member 624 cooperates with the guiding mechanism 70 to achieve accurate stacking of the lower structure 12 of the second double-headed waterproofing membrane with the lower structure 12 of the first double-headed waterproofing membrane. Moreover, with the action of the traveling mechanism, the pressing member 624 also moves with it, and pushes away the upper structure 11 of the second double-headed waterproofing membrane that has been laid on the ground, thereby improving the separation effect of the upper structure 11 and the lower structure 12 in the overlapped portion of the second double-headed waterproofing membrane.

[0051] In a further embodiment, the guide mechanism 70 further includes: a first transmission member 76, a second transmission member 77, a third transmission member 78, a fourth transmission member 79 and a driving member 710. The first transmission member 76 and the second transmission member 77 are respectively disposed at the ends of the first guide roller 73 and the second guide roller 74. The third transmission member 78 is disposed between the first transmission member 76 and the second transmission member 77 and is meshedly connected to the first transmission member 76 and the second transmission member 77. The fourth transmission member 79 is transmission-connected to the first transmission member 76 or the second transmission member 77. The driving member 710 is transmission-connected to the fourth transmission member 79. The driving member 710 is a motor.

[0052] In the above technical solution, the fourth transmission member 79 is driven to rotate by the driving member 710, and then the first transmission member 76 (or the second transmission member 77) is driven to rotate, and then the third transmission member 78 is driven to rotate, and then the second transmission member 77 (or the first transmission member 76) is driven to rotate, and the first guide roller 73 and the second guide roller 74 are driven to rotate. Through the rotation of the first guide roller 73 and the second guide roller 74, a stable driving force can be provided, so that the lower structure 12 of the overlapped part of the second double-headed waterproof coiled material can be separated from the coiled material smoothly and continuously, and transported along a predetermined path. This helps to ensure that the lower structure 12 will not be stuck, offset or torn during the transportation process, thereby improving the stability and reliability of coiled material processing.

[0053] Through the guidance of the first guide roller 73, the second guide roller 74, and the third guide roller 75, the lower structure 12 can be accurately transported to a position opposite to the first double-head waterproofing membrane lower structure 12, so that the two can be accurately stacked. This stacking method not only helps to maintain the flatness and tightness of the membrane, but also ensures the bonding effect between the membranes, thereby improving the overall quality and performance of the waterproof layer.

[0054] In a further embodiment, Figure 8As shown, the guide mechanism 70 further includes: a slide groove, a slider 711, a telescopic member 712, and a support frame 713. The slide groove is arranged in the support frame 72. The slider 711 is arranged in the slide groove and is slidably connected to the slide groove; a through hole is arranged in the slider 711. The telescopic member 712 is arranged in the slide groove and its output end is connected to the slider 711; the telescopic member 712 is a cylinder. The telescopic member 712 drives the sliding and lifting. The support frame 713 is arranged on the side of the support frame 72; the third guide roller 75 is hinged to the support frame 713 through the through hole.

[0055] In the above technical solution, the telescopic member 712 drives the slider 711 to rise and fall, and then the slider 711 drives the third guide roller 75 to rotate, thereby adjusting the contact pressure between the third guide roller 75 and the lower structure 12 of the overlapping portion of the second double-headed waterproof coiled material. This pressure adjustment helps to ensure that the coiled material maintains a stable tension and speed during the conveying process, thereby avoiding problems such as deviation, tearing or accumulation of the coiled material due to excessive or insufficient tension.

After the lower structure 12 of the second double-headed waterproofing roll is unwound, it contacts the lower structure 12 of the first double-headed waterproofing roll, and is melt-bonded under the action of the heating component 52; Step three: place the upper structure 11 of the first double-headed waterproof membrane on the lower structure 12 of the second double-headed waterproof membrane, and use the heating component 52 to melt and bond the two; place the upper structure 11 of the second double-headed waterproof membrane on the upper structure 11 of the first double-headed waterproof membrane, and use the heating component 52 to melt and bond the two, thereby completing the overlap of the first double-headed waterproof membrane and the second double-headed waterproof membrane.
