Description

Technical Field

[0001] This utility model relates to the field of waterproof membrane laying technology, and in particular to a portable handheld device for flattening waterproof membranes for color steel roofs. Background Technology

[0002] Waterproof membrane flattening device is a key tool in building waterproofing construction. Its core function is to use mechanical pressure to make the waterproof membrane adhere to the substrate (such as roof, basement, etc.) without gaps, eliminate air residue and ensure the membrane is dense, thereby ensuring the continuity and airtightness of the waterproof layer.

[0003] In complex construction scenarios, such as roofs with ridges (e.g., gable roofs), handheld waterproof membrane flattening devices are widely used due to their lightweight and flexible characteristics. However, traditional handheld devices have significant technical limitations: their pressure rollers typically employ a fixed-angle design (e.g., single-roller or parallel double-roller structure), making dynamic angle adjustment impossible based on the slope of the ridge (often symmetrically arranged in a figure-eight shape). When facing roof ridges with varying slopes or irregular shapes, poor contact between the fixed pressure roller and the membrane, along with deviations in the angle between the roller and the slope, can lead to localized blistering, curling, or even tearing of the membrane, compromising the integrity of the waterproofing layer. Utility Model Content

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. The term "embodiment" as used herein refers to a particular feature, structure, or characteristic that may be included in at least one implementation of the present invention.

[0025] Example 1

[0026] Reference Figures 1-5 This embodiment provides a portable handheld color steel roof waterproof membrane flattening device, specifically including a base plate 1, a flat roller 2 for flattening the membrane connected to the base plate 1, and a figure-eight roller 3 for pressing the sides of the roof ridge. The figure-eight roller 3 is connected to an angle adjustment mechanism, and a locking mechanism for fixing the angle adjustment mechanism is provided on the top of the base plate 1.

[0027] An inner rod is rotatably connected inside the figure-eight pressure roller 3. One end of the inner rod is fixedly connected to a rotating shaft 8, which is hinged to the bottom of the base plate 1. One side of the rotating shaft 8 is connected to an angle adjustment mechanism. The angle adjustment mechanism includes a meshing rack 401 and a gear 402. The rack 401 is slidably connected to the base plate 1, and one side of the gear 402 is fixedly connected to the rotating shaft 8. Several insertion holes 403 are provided on the side of the rack 401 located above the base plate 1. The locking mechanism includes a fixing block 501 fixedly connected to the base plate 1. A pin 502 is slidably connected inside the fixing block 501, and the pin 502 cooperates with the insertion holes 403 to fix the rack 401. A spring 503 is fitted on the pin 502 to prevent it from disengaging from the insertion hole 403.

[0028] The base plate 1 adopts a rectangular design or a V-shaped cross-section design. A through hole is provided on the base plate 1, and the rack 401 is located in the through hole and slidably connected to the base plate 1. The part of the rack 401 located above the base plate 1 is provided with a protrusion plate to limit the range of motion of the rack 401.

[0029] The rack 401 has teeth on both sides of the portion below the base plate 1, which mesh with two gears 402 respectively. Multiple insertion holes 403 are evenly spaced. When the pin 502 is pulled out of the insertion hole 403, one of the figure-eight pressure rollers 3 is turned by hand. Under the action of the two gears 402 and the rack 401, the two figure-eight pressure rollers 3 open or close simultaneously to achieve angle adjustment. The pin 502 is inserted into different insertion holes 403 to correspond to different opening angles.

[0030] A U-shaped plate 6 is fixedly connected to the base plate 1. Side plates 7 are slidably connected to both ends of the U-shaped plate 6. An inner rod is fixedly connected to one side of the side plate 7, and the inner rod is rotatably connected to the flat pressure roller 2. A handle 9 is fixedly connected to the top of the base plate 1. The flat pressure roller 2 is cylindrical.

[0031] The flat pressure roller 2 and the figure-eight pressure roller 3 rotate along the axis of the inner rod. The inner rod is equipped with a limiting device to restrict the axial sliding of the flat pressure roller 2 and the figure-eight pressure roller 3 on the inner rod. Both ends of the U-shaped plate 6 are provided with cavities, and the side plate 7 can slide in the cavity to realize the height adjustment of the flat pressure roller 2. The side plate 7 and the U-shaped plate 6 are fixedly connected by bolts.

[0032] Example 2

[0033] The difference between this embodiment and Embodiment 1 is that the flat pressure roller 2 is shaped like a truncated cone. The inclined structure of the truncated cone pressure roller can gradually disperse the pressure from the center to the edge, avoiding local over-pressure or under-pressure. Compared with the cylindrical pressure roller, it can compress the waterproof membrane more densely, adapt to complex construction scenarios, improve construction efficiency, reduce membrane damage and enhance compaction uniformity.

[0034] Working principle: When laying the waterproof membrane at the roof ridge, first, pull the pin 502 to disengage it from the insertion hole 403. Adjust the angle of the figure-eight rollers 3 according to the slope of the roof ridge, ensuring that the two figure-eight rollers 3 fit as closely as possible to the roof ridge. Then, loosen the pin 502 and finely adjust the angle of the figure-eight rollers 3 so that the pin 502 inserts into the nearest insertion hole 403, thereby fixing the rack 401 and achieving angle adjustment of the figure-eight rollers 3. Adaptively adjust the height of the two flat rollers 2 according to the height of the flat areas on both sides of the roof ridge to facilitate pressing the membrane. After the above adjustments are completed, hold the handle 9 and press down while pushing back and forth along the roof ridge to press and lay the waterproof membrane.

[0035] Importantly, although only a few embodiments are described in detail in this disclosure, those who consult this disclosure will readily understand that many modifications are possible without substantially departing from the subject matter described in this application, such as changes in the size, structure, shape, and proportion of various elements, as well as variations in temperature, pressure, installation arrangement, material use, color, orientation, etc.; for example, an element shown as integrally formed may be composed of multiple parts or elements, and the position of the elements may be inverted or otherwise altered; therefore, all such modifications should be included within the scope of this invention, and other substitutions, modifications, alterations, and omissions may be made in the design, operation, and arrangement of the exemplary embodiments without departing from the scope of this invention.
