Description

Technical Field

[0001] The utility model relates to the technical field of waterproof coiled materials, in particular to a self-adhesive waterproof coiled material. Background Art

[0002] Adhesive waterproofing membrane is a kind of waterproof material, which is usually used in waterproofing projects in buildings. It is usually made of polymer modified asphalt or other synthetic polymer materials, with adhesive on the surface, which is convenient for sticking to the surface of the building structure during construction.

[0003] In order to facilitate storage and transportation, the coils are usually packaged into rolls. The existing Chinese patent with the authorization announcement number CN219824062U discloses a self-adhesive film waterproofing coil. It is provided with a specific composite material layer, so that it has good waterproof performance and also has the characteristics of heat resistance, heat preservation and flame retardancy. However, the protective coiled material after packaging lacks the restraint of the packaging film and lacks restrictions during use, and is prone to scattering and deformation, and even causing damage to the coiled material. In addition, during the construction process, it cannot be guaranteed that the coiled material is completely attached to the surface of the building structure, and bubbles or gaps are easily generated, which affects the waterproof effect.

[0004] In summary, the current self-adhesive waterproof membrane still has the following defects during installation and use at the user end:

[0005] (1) The protective rolls after packaging lack the restraint of the packaging film and are not restricted during use, so they are easy to scatter and deform, and even cause damage to the rolls;

[0006] (2) During the construction process, it is not possible to ensure that the membrane is completely attached to the surface of the building structure, which may easily generate bubbles or gaps, affecting the waterproofing effect; Utility Model Content

[0007] In order to overcome the above-mentioned defects of the prior art, the inventors conducted in-depth research and completed the present utility model after paying a lot of creative work.

[0008] Specifically, the technical problem to be solved by the utility model is to provide a self-adhesive waterproof membrane to solve the problem that the current self-adhesive waterproof membrane lacks the restraint of a packaging film and is not restricted during use, so it is easy to scatter and deform, and even cause damage to the membrane. In addition, during the construction process, it cannot be guaranteed that the membrane is completely attached to the surface of the building structure, and bubbles or gaps are easily generated, which affects the waterproof effect.

[0009] In order to solve the above technical problems, the technical solution of the utility model is:

[0010] A self-adhesive waterproofing coiled material comprises a base and a winding roller, wherein the winding roller is mounted on the top of the base, a winding mechanism is arranged on the top of the base, the winding mechanism comprises a protective member, the protective member comprises a sleeve column, one end of the sleeve column is hinged to the top of the base, a traction shaft is movably connected to the inner side of the sleeve column, a spring is arranged on the outer side of the traction shaft and in the sleeve column, a deflection shaft is connected to the end of the traction shaft away from the sleeve column, one end of the deflection shaft is also hinged to the top of the base, and a spring is fixedly mounted on the other end of the deflection shaft. The first pressing cylinder is arranged in parallel with the winding roller. The winding roller can be driven by an external motor to wind up the waterproof coil by rotating. The sleeve can be deflected at an angle on the base to form a triangular structure together with the traction shaft and the base. When the device is not in use, the spring is in an extended state, pushing the deflection axis connected to the traction shaft to deflect toward the side close to the base to limit the coil after unwinding. The first pressing cylinder is arranged in parallel with the winding roller, so that the coil on the winding roller is not easily deformed when passing through the first pressing cylinder.

[0011] As an improved technical solution, a threaded shaft is movably connected to the inner side of the first pressing barrel, and the threaded shaft runs through the entire first pressing barrel. The threaded shaft is arranged parallel to the winding roller. A thread is provided on the outer side of the first pressing barrel. The first pressing barrel is located on the outer side of the threaded shaft where no thread is provided, and the threaded shaft can rotate on the inner side of the first pressing barrel.

[0012] As an improved technical solution, the end of the threaded shaft away from the first pressing barrel is threadedly connected to the second pressing barrel, and the threaded shaft runs through the entire second pressing barrel. A slider is movably connected to the top of the second pressing barrel and the top of the base. The slider is connected to the second pressing barrel through the deflection shaft. A thread that matches the threaded shaft is provided on the inner side of the second pressing barrel, and when the threaded shaft rotates, it moves along the outer side of the threaded shaft toward the side of the first pressing barrel. The deflection shafts are arranged parallel to each other, and the slider can move along the groove in the base.

[0013] As an improved technical solution, a guide shaft is provided on the inner side of the slider and on the top of the base, and the guide shaft runs through the entire slider. The deflection shaft is hinged to the top of the base through the guide shaft. When the deflection shaft deflects, the guide shaft is the center of the circle, and the deflection angle of the deflection shaft is always the same, so that the first pressing barrel and the second pressing barrel are always on the same straight line.

[0014] As an improved technical solution, the winding mechanism also includes a coil body, which includes a main substrate, an air supply cavity is opened on the inner side of the main substrate, an airbag area is arranged on the top of the main substrate, the airbag area is communicated with the inside of the air supply cavity, a first isolation layer is arranged on the side of the airbag area away from the main substrate, and the airbag area is located at the bottom of the first isolation layer in the winding mechanism. The airbag area can act as a pressure balance regulator during the construction process to ensure that the coil can apply pressure evenly when it is attached to the surface of the building structure to avoid the occurrence of bubbles or gaps. The number of airbag areas can be cut and divided according to actual usage requirements.

[0015] As an improved technical solution, a deformation zone is provided on the side of the main substrate away from the airbag zone, and an adhesive layer is provided on the inner side of the deformation zone. The adhesive layer fills the inner side of the deformation zone, and the adhesive layer is made of synthetic polymer glue material. When the airbag zone expands, the deformation zone can be deformed so that the adhesive layer can be bonded to the surface of the building. The synthetic polymer glue in the adhesive layer is a special glue, which is usually made of synthetic polymer as the main component, with appropriate amounts of additives and solvents added, and is produced through special processing. The synthetic polymer glue has excellent bonding properties and weather resistance.

[0016] As an improved technical solution, a second isolation layer is provided on the side of the main substrate facing away from the first isolation layer, and the adhesive layer is located between the main substrate and the second isolation layer. The first isolation layer and the second isolation layer can isolate the waterproof layer in the main substrate from the building structure and prevent the adhesive in the adhesive layer from penetrating into the interior of the building material.

[0017] As an improved technical solution, the first isolation layer and the second isolation layer are made of the same material, specifically one of glass fiber cloth, polypropylene film, and polyethylene film, and the thickness of both is 0.5mm to 1.5mm. The thickness of the first isolation layer and the second isolation layer can be determined according to actual use requirements. Thinner models may be more suitable for use on flatter surfaces, and can better fit the surface of the building structure, while reducing the impact of additional thickness on the construction process. Thicker models may be more suitable for use on uneven or concave and convex surfaces, and can fill the unevenness of the surface, increase the contact area between the waterproof membrane and the surface of the building structure, and improve the isolation effect.

[0018] After adopting the above technical solution, the beneficial effects of the utility model are:

[0019] (1) When the self-adhesive waterproofing membrane is in use, the angle of the sleeve column hinged on the top of the base is deflected to adapt to the size of the main body of the unrolled membrane. When there is no restriction of the packaging film, the spring in the sleeve column recovers and stretches, pushing the deflection axis connected to the traction shaft to deflect toward the side close to the base, thereby restricting the unrolled membrane and making it less likely to be damaged or deformed.

[0020] (2) The first pressing cylinder and the second pressing cylinder are always in the same straight line and parallel to the guide axis through the deflection axis, thereby meeting the protection requirements for coil bodies of different lengths.

[0021] (3) The number of airbag areas can be cut and divided according to actual usage requirements, and the airbag areas are inflated through the interconnected air supply cavity, acting as a pressure balance regulator during the construction process to ensure that the roll material can apply pressure evenly when it is attached to the surface of the building structure, avoiding the occurrence of bubbles or gaps, and ensuring the waterproof effect.

[0034] The inner side of the sleeve column 311 is movably connected with a traction shaft 312, and a spring 313 is arranged on the outer side of the traction shaft 312 and in the sleeve column 311. The end of the traction shaft 312 away from the sleeve column 311 is connected to a deflection shaft 314, and one end of the deflection shaft 314 is also hinged on the top of the base 1, and the other end of the deflection shaft 314 is fixedly installed with a first pressing cylinder 315. The first pressing cylinder 315 is arranged in parallel with the winding roller 2, and the winding roller 2 can be driven by an external motor to rewind the waterproofing coil by rotation. The sleeve column 311 can be deflected at an angle on the base 1 to form a triangular structure with the traction shaft 312 and the base 1.

Example 2

[0039] like Figures 1 to 5 The second embodiment of the utility model is shown together, and the difference between this embodiment and the first embodiment is that:

[0040] The winding mechanism 3 also includes a coil body 32, which includes a main substrate 321. An air supply cavity 322 is opened on the inner side of the main substrate 321. An air bag area 323 is arranged on the top of the main substrate 321. The air bag area 323 is communicated with the inside of the air supply cavity 322. A first isolation layer 324 is arranged on the side of the air bag area 323 away from the main substrate 321. The air bag area 323 is located at the bottom of the first isolation layer 324 in the winding mechanism 3.

The number of air bag areas 323 can be cut and divided according to actual usage requirements.

[0041] A deformation zone 325 is provided on the side of the main substrate 321 facing away from the airbag zone 323, and an adhesive layer 326 is provided on the inner side of the deformation zone 325. The adhesive layer 326 is filled on the inner side of the deformation zone 325. The adhesive layer 326 is made of a synthetic polymer glue material. When the airbag zone 323 expands, the deformation zone 325 can be deformed so that the adhesive layer 326 can be bonded to the surface of the building. The synthetic polymer glue in the adhesive layer 326 is a special glue, which is usually made of a synthetic polymer as the main component, with an appropriate amount of additives and solvents added, and is produced through special processing.

The first isolation layer 324 and the second isolation layer 327 can isolate the interaction between the waterproof layer in the main substrate 321 and the building structure, and prevent the adhesive in the adhesive layer 326 from penetrating into the interior of the building material.

[0043] The first isolation layer 324 and the second isolation layer 327 are made of the same material, specifically one of glass fiber cloth, polypropylene film, and polyethylene film, and the thickness of both is 0.5mm to 1.5mm. The thickness of the first isolation layer 324 and the second isolation layer 327 can be determined according to actual usage requirements. Thinner models may be more suitable for use on flatter surfaces and can better fit the surface of the building structure while reducing the impact of additional thickness on the construction process. Thicker models may be more suitable for use on uneven or concave and convex surfaces and can fill in the unevenness of the surface, increase the contact area between the waterproof membrane and the surface of the building structure, and improve the isolation effect.

[0044] During use, the main substrate 321 in the coil body 32 is used as the basis, and the first isolation layer 324 and the second isolation layer 327 are used on both sides to increase its structural strength and improve its wear resistance. The deformation zone 325 opened at the bottom of the main substrate 321 makes the coil body 32 have good deformation performance and can adapt to the exterior surfaces of buildings of different shapes. The adhesive layer 326 made of synthetic polymer glue has excellent bonding performance and weather resistance, and can better fit the building with the first isolation layer 324 and the second isolation layer 327 of different thicknesses and the same material. The waterproof membrane can be applied to the surface of the building structure to reduce the impact of the extra thickness on the construction process, or is suitable for use on uneven or concave-convex surfaces, can fill the uneven surface, increase the contact area between the waterproof membrane and the surface of the building structure, so as to improve the isolation effect; and the number of air bag areas 323 that can be cut and divided according to actual use needs and the air bag areas 323 are inflated through the interconnected air supply cavity 322 to act as a pressure balance regulator during the construction process to ensure that the membrane can apply pressure evenly when it fits the surface of the building structure to avoid bubbles or gaps and ensure the waterproof effect.
