Description

Technical Field

[0001] This utility model belongs to the field of waterproof membrane sealing technology, and in particular relates to a rolling waterproof membrane sealing tool. Background Technology

[0002] Waterproof membranes effectively prevent water penetration and protect building structures from water damage. As a crucial component of building waterproofing projects, the quality of waterproof membrane installation directly affects the overall quality of the building and also directly impacts maintenance costs. Therefore, the quality of waterproof membrane installation holds an extremely important position in building engineering. Currently, the main methods for waterproof membrane installation include cold bonding, hot bonding, hot-melt bonding, and self-adhesive bonding. During installation, to ensure the continuity and integrity of the waterproof layer, waterproof membranes typically need to be overlapped. Traditional rolling tools are commonly used to seal these overlaps; however, the single-roller operation results in a small contact area, leading to issues such as voids in the overlaps and inadequate edge sealing at the joints. Alternatively, workers may use traditional edge-sealing trowels for sealing. However, traditional edge-sealing trowels have a small contact area with the membrane overlaps, and the sealing direction is difficult to control, making it difficult to guarantee the sealing quality.

[0003] Therefore, there is an urgent need for a simple and reasonably designed rolling-type waterproof membrane sealing tool. By setting up a front rolling roller and a rear right rolling roller or a front rolling roller and a rear left rolling roller, the two rolling operations can effectively solve the problem of hollow areas and roll the membrane overlap joints again to seal the membrane, thereby improving the sealing effect and usage flexibility of the waterproof membrane.

The bolts pass through the countersunk mounting holes on the mounting plate 3-1 and extend into the threaded holes in the first cylindrical rod 3-5 or the second cylindrical rod 3-6 to achieve connection.

[0050] In this embodiment, in actual use, the end of the transverse connecting rod 8-1 is welded to the mounting plate 3-1.

[0051] In this embodiment, during actual use, the rear left roller 3-4 and the rear right roller 2-4 can rotate relative to the rear axle 3-3. The rear axle 3-3 passes through the ends of the two mounting plates 3-1 and is fitted with a rear side nut 3-2. The rear axle 3-3 is mounted on the two mounting plates 3-1, and the rear side nut 3-2 is tightly fitted to the mounting plate 3-1 so that the rear left roller 3-4 and the rear right roller 2-4 are positioned between the two mounting plates 3-1.

[0052] In this embodiment, a stepped portion is formed at the middle large diameter portion 5-1 and the small diameter end portion 5-2 to facilitate the fitting and limiting installation of the first clamping plate 6-1, the supporting connecting plate 6-3 and the second clamping plate 6-2. The end of the small diameter end that extends out of the first clamping plate 6-1 is provided with an upper locking nut 6-5 to lock it in place, thereby realizing the installation of the extension support 6.

[0053] In this embodiment, in actual use, the spring 8-3 can refer to the structure of a conventional exhaust pipe spring in the art. Hooks are provided at both ends of the spring 8-3; one end of the spring 8-3 is hooked into the upper connecting lug 8-4, and the other end of the spring 8-3 is hooked into the lower connecting lug 8-2. In actual use, the tilting requirement of the tool handle 4 can be met by replacing the spring 8-3.

[0054] In this embodiment, in the initial state, when the handle 7 is vertically positioned, the spring 8-3 is in the normal state. When the handle 7 is tilted, the extension support 6 is adjusted to rotate around the small diameter end 5-2. When the extension support 6 rotates around the small diameter end 5-2, the bottoms of the front rolling roller 1-4, the rear left rolling roller 3-4, and the rear right rolling roller 2-4 are aligned, and the spring 8-3 extends. After adjustment, the upper locking nut 6-4 needs to be operated to achieve relative locking of the extension support 6.

[0055] In this embodiment, during actual use, a spring 8-3 is provided, which acts on the rear left rolling roller 3-4 and the rear right rolling roller 2-4 through the lower connecting ear 8-2 and the transverse connecting rod 8-1 to facilitate synchronous adjustment and to facilitate rolling with the front rolling roller 1-4, thereby better acting on the rolling and rolling of the waterproof membrane.

[0056] In this embodiment, the upper locking nut 6-4 is provided so that after the extension support 6 rotates around the small diameter end 5-2 into place, the upper locking nut 6-4 can be tightly fitted to the first clamping plate 6-1, thereby achieving relative locking of the extension support 6.

[0057] In specific use of this utility model, when the waterproof membrane is closed, if the left waterproof membrane overlaps the right waterproof membrane, the operating handle 7 is tilted, and the extension support 6 is adjusted to rotate around the small diameter end 5-2. After it is in place, the upper locking nut 6-4 is tightly attached to the first clamping plate 6-1, thereby realizing the relative locking of the extension support 6 and realizing the adjustment of the tilt angle of the tool until the operation requirements are met. Then the tool is moved to the overlap of the waterproof membrane so that the right side of the rear right rolling roller 2 and the front rolling roller 1 coincide with the overlap seam.

[0058] The tool is manually moved and pressed down by the handle 7. The front rolling roller 1-4 rolls and presses down the overlapping area of ​​the waterproof membrane edge, while the rear right rolling roller 2-4 rolls down and presses down the joint of the waterproof membrane, so as to achieve a tight sealing effect. In this way, the two rolling of the front rolling roller 1-4 and the rear right rolling roller 2-4 not only effectively solves the problem of hollowness, but also compacts the overlapping joint of the membrane again, improving the sealing effect of the waterproof membrane.

[0059] If the right waterproof membrane overlaps the left waterproof membrane, move the tool to the overlap of the waterproof membrane so that the left side of the rear left rolling roller 3 and the front rolling roller 1 coincide with the overlap seam.

[0060] The tool is manually moved and pressed down by the handle 7. The front rolling rollers 1-4 roll and press the overlapping edge of the waterproof membrane, while the rear left rolling rollers 3-4 roll and press the joint of the waterproof membrane, so as to achieve a tight sealing effect and improve the sealing effect of the waterproof membrane.

[0061] In summary, this utility model has a simple structure and reasonable design. By setting the front rolling roller and the rear right rolling roller or the front rolling roller and the rear left rolling roller together, the two rolling processes not only effectively solve the problem of hollowness, but also roll and seal the overlap of the membrane, thereby improving the sealing effect and the flexibility of use of the waterproof membrane.

[0062] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model. Any simple modifications, alterations, or equivalent structural changes made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
