[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0032] In existing technologies, the installation of building waterproofing membranes mostly relies on manual unrolling and laying. Workers need to repeatedly bend over to unfold the rolls and adjust their position. In windy weather, the unfolded membrane is easily blown away, leading to misalignment or material damage, severely impacting construction progress. Especially in large-area flat construction scenarios, traditional manual operation requires multiple people to work together to position and tension the fabric, resulting in high labor intensity and safety hazards.

[0033] To address the aforementioned issues, the applicant observed that the lack of an effective guiding mechanism during manual fabric deployment in traditional construction processes easily leads to deviations in the fabric's unfolding trajectory. Analysis revealed that installing a rigid support structure on the fabric transport carrier can both support the weight of the roll and guide its unfolding direction. Further research showed that integrating the propulsion and fabric release mechanisms into a single design allows the thrust to be directly converted into the fabric's unfolding power, thus enabling manual operation by a single person.

[0034] Therefore, as Figures 1-5 As shown, this utility model proposes a technical solution including a laying pole 1 and a handheld frame 2. A waterproof cloth installation area 5 is set below the laying pole 1, and the handheld frame 2 is located above the laying pole 1 and fixedly connected to the pole. When the operator pushes the handheld frame 2, the laying pole 1 drives the waterproof cloth to complete the continuous laying.

[0035] The laying pole 1 is a rigid support structure that carries the waterproof fabric roll. It can be implemented using a welded rectangular steel pipe frame, with its lateral length matching the width of the waterproof fabric. The waterproof fabric installation area 5 is the roll fixing area located below the pole. Specifically, the waterproof fabric roll mandrel can be fixed using pins or slot structures to ensure stable rotation and release of the roll during movement. The handheld frame 2 is the propulsion mechanism for the operator to apply force. It can be a portal steel pipe frame connected to the laying pole 1 to form a rigid integral structure.

[0036] Specifically, when the operator holds the handheld lever 22 at the top of the second connecting frame 21 and pushes it forward, the laying rod 1 moves the waterproof fabric roll fixed below it synchronously. As the rod moves, the roll generates rolling friction upon contact with the ground, causing the waterproof fabric to automatically unfold along the laying direction. The limiting structure set in the width direction of the laying rod 1 prevents the fabric from shifting laterally, and the rigid connection between the handheld frame 2 and the laying rod 1 ensures the straightness of the fabric release trajectory during the pushing stroke.

[0037] Compared to existing technologies, traditional manual laying requires two people to control the ends of the fabric for positioning. This invention, however, utilizes a rigid laying rod 1 to achieve simultaneous single-handed pushing and fabric guidance. Traditional methods require repeated adjustments to the fabric position under wind interference; the rod's own weight and structural rigidity effectively suppress fabric swaying caused by wind, ensuring the stability of continuous laying.

[0038] Through the above technical solution, this utility model enables continuous laying of waterproof fabric by a single person with one hand, eliminating the physical exertion caused by manually bending over and dragging the fabric. The laying pole 1 simultaneously releases the fabric and controls its trajectory during the advancement process, avoiding fabric wrinkles or overlaps caused by errors in coordination among multiple people in traditional methods. The rigid structure provides stable support under wind conditions, significantly improving the consistency of construction quality.

[0039] See also Figures 1-3 As shown, the present invention further includes a leveling mechanism 3, which is located behind the laying pole 1 and moves with the laying pole 1 to level the waterproof cloth being laid.

[0040] Specifically, such as Figure 1-3 As shown, the leveling mechanism 3 includes a first connecting frame 31 and a brush 32. The first connecting frame 31 is detachably mounted on the laying pole 1, and the brush 32 is fixedly mounted on the first connecting frame 31. The brush 32 is arranged along the width direction of the laying pole 1.

[0041] The leveling mechanism 3 is a device used to eliminate wrinkles or deviations generated during the laying of waterproof fabric. Specifically, it can be achieved by combining a detachable rigid first connecting frame 31 with a flexible brush 32, and perform surface treatment on the laid waterproof fabric by following the movement trajectory of the laying rod 1.

[0042] The first connecting frame 31 is a support structure for fixing the brush 32. It can be made of metal rods or plastic frames spliced ​​together and can be detachably connected to the laying pole 1 by bolts or buckles.

[0043] The brush 32 is a cleaning component with multiple flexible fibers, which can be made of nylon or polypropylene. By arranging them along the width of the laying rod 1 to form a continuous contact surface, it can smooth out the undulations on the surface of the waterproof cloth during movement.

[0044] Specifically, when the laying pole 1 is pushed forward by the handheld frame 2, the leveling mechanism 3 moves synchronously. The first connecting frame 31 is detachably installed at the rear end of the laying pole 1, and the brush 32 is fixedly installed on the first connecting frame 31, with its bristles contacting the unfolded waterproof fabric surface. Since the length direction of the brush 32 is consistent with the width direction of the laying pole 1, the friction generated between the fibers of the brush 32 and the waterproof fabric during the movement can eliminate wrinkles on the fabric surface and push the fabric surface that has shifted due to wind or inertia back to its original position. The linkage between the leveling mechanism 3 and the laying pole 1 avoids manual secondary finishing operations, forming a continuous automatic leveling process.

[0045] Compared with existing technologies, traditional manual laying requires additional workers to manually smooth the fabric surface. However, this utility model completes the smoothing action simultaneously during the laying process through a mechanical linkage structure. That is, through the combination of the rigid first connecting frame 31 and the flexible brush 32, the smoothing action and the laying action form a continuous work flow, eliminating fabric surface defects without interrupting the laying process.

[0046] Through the above technical solution, this utility model can maintain the flatness of the waterproof fabric in windy conditions, eliminating fabric displacement or wrinkles caused by wind disturbance. The synchronous movement mechanism of the leveling mechanism 3 and the laying rod 1 combines the originally step-by-step laying and tidying operations into a single step, reducing the frequency of manual intervention and improving construction continuity. The arrangement of the brushes 32 along the width direction ensures full coverage of the entire waterproof fabric surface, avoiding unevenness in local areas.

[0047] Detailed, such as Figure 1 As shown, the first connecting frame 31 includes a first rod 311 and a second rod 312. The first rod 311 is symmetrically arranged on both sides of the handheld frame 2. The second rod 312 is fixedly arranged at the end of the first rod 311. The second rod 312 is arranged along the width direction of the laying rod 1. The brush 32 is installed on the second rod 312.

[0048] The first rod 311 refers to the support structure symmetrically distributed on both sides of the handheld frame 2. Specifically, it can be implemented using metal tubing or composite material rods. Its symmetrical arrangement can enhance the overall stability of the first connecting frame 31 and prevent the brush 32 from tilting during movement.

[0049] The second rod 312 is a transverse support member connected to the end of the first rod 311. Its arrangement along the width of the laying rod 1 expands the coverage area of ​​the brush 32, ensuring the flatness of the waterproof fabric edges. The brush 32 is a flexible component used to flatten the waterproof fabric. Specifically, it can be implemented using a combination structure of nylon or polyester fiber bristles and a rigid base. It is installed on the second rod 312 by means of a snap-fit, facilitating disassembly and maintenance.

[0050] Specifically, when the handheld frame 2 pushes the laying pole 1, the first pole 311 forms a stable support frame through symmetrical distribution, while the second pole 312 extends along the width of the laying pole 1, driving the brush 32 to continuously smooth the laid waterproof fabric. For example, the end of the first pole 311 is perpendicularly connected to the second pole 312, so that the direction of force applied by the brush 32 is consistent with the laying direction of the waterproof fabric, thereby avoiding wrinkles on the fabric surface caused by uneven force.

[0051] Furthermore, the length of the second rod 312 can be adjusted according to the width of the waterproof fabric, for example, by changing its extension range through a telescopic structure or splicing components, to adapt to the needs of different construction scenarios.

[0052] As a preferred embodiment, such as Figure 1 As shown, the laying pole 1 includes a horizontal bar 11 and a vertical bar 12. The horizontal bar 11 is fixedly installed below the handheld frame 2, and the vertical bar 12 is fixedly installed at both ends of the horizontal bar 11 and is set opposite to the handheld frame 2. The waterproof cloth installation area 5 is located between the vertical bars 12.

[0053] The horizontal bar 11 is a horizontal support structure rigidly connected to the handheld frame 2. It can be made of metal tubing or composite materials and serves to provide an installation foundation for the vertical bar 12 and transmit thrust. The vertical bar 12 is a longitudinal support structure perpendicular to the horizontal bar 11. It can be fixed to both ends of the horizontal bar 11 by welding or bolting, defining the lateral boundary of the waterproof fabric installation area 5 and maintaining the stability of the waterproof fabric when unfolded. The waterproof fabric installation area 5 is the spatial area enclosed by the vertical bars 12 and the horizontal bar 11 on both sides. The spacing of the vertical bars 12 can be adjusted to accommodate waterproof fabric rolls of different widths, providing a directional unfolding path for the waterproof fabric.

[0054] Specifically, when the handheld frame 2 is pushed, the horizontal bar 11 transmits the thrust to the vertical bar 12 through a rigid connection, and the two vertical bars 12 contact the ground to form rolling or sliding support. The waterproof fabric roll is placed in the installation area between the vertical bars 12. As the laying pole 1 moves, the waterproof fabric gradually unfolds from the bottom of the installation area and lies flat on the ground. The length of the horizontal bar 11 can be set as a telescopic structure according to actual needs, for example, by using a telescopic sleeve to expand the width, while the height of the vertical bar 12 can be set to adapt to different terrains or the diameter of the roll.

[0055] Furthermore, the crossbar 11 is preferably a telescopic crossbar 11.

[0056] The telescopic crossbar 11 is a rod-shaped structure with an adjustable length. Specifically, it can be implemented using a sleeve-type telescopic structure or a hydraulic telescopic mechanism. Through the telescopic function, the length of the crossbar 11 can be adapted to the installation requirements of waterproof fabric rolls of different widths.

[0057] Specifically, when different widths of waterproof fabric need to be laid, the telescopic crossbar 11 can be adjusted in length to match the size of the roll material. For example, when unfolding a wider waterproof fabric, the operator can loosen the locking bolts, pull the inner tube outward to the required length, and then re-secure it. When entering narrow spaces, the crossbar 11 can be shortened to reduce the overall width of the equipment. This structure allows the same device to be compatible with multiple specifications of waterproof fabric rolls, avoiding the need to change equipment due to changes in roll width.

[0058] Further details can be found by referring to [link / reference]. Figure 1 As shown, rollers 121 are provided on both sides of the vertical bar 12. The rollers 121 are located in the waterproof cloth installation area 5, and their central axis is consistent with the extension direction of the horizontal bar 11.

[0059] Roller 121 is a circular rotatable component installed on vertical rod 12. Specifically, it can be a rubber wheel or a plastic wheel with bearings. Its function is to contact the ground during the laying process and reduce the friction between the waterproof cloth and the ground by rolling.

[0060] The central axis is aligned with the extension direction of the crossbar 11, meaning the rotation axis of the roller 121 is parallel to the length direction of the crossbar 11. This can be achieved by mounting the roller 121 on a fixed shaft aligned with the extension direction of the crossbar 11, thereby ensuring that the rolling direction of the roller 121 is aligned with the moving direction of the laying pole 1, thus avoiding lateral deviation.

[0061] Specifically, rollers 121 are symmetrically arranged at the bottom of the vertical bar 12. When the handheld frame 2 pushes the laying pole 1 forward, the rollers 121 contact the ground and roll along the laying direction. Since the axis of the rollers 121 is consistent with the extension direction of the horizontal bar 11, the rolling direction of the rollers 121 is always parallel to the moving trajectory of the laying pole 1.

[0062] As a preferred embodiment, such as Figure 1 As shown, the handheld frame 2 includes a handheld rod 22 and a second connecting frame 21. The handheld rod 22 and the crossbar 11 are fixed on both sides of the second connecting frame 21, which is in the shape of a door.

[0063] The handheld lever 22 is a lever-shaped component for the operator to hold. It can be made of metal tubing with anti-slip texture on the surface, which makes it easy to apply force to push the laying pole 1 to move.

[0064] The second connecting frame 21 is a support structure that connects the hand handle 22 and the crossbar 11. Specifically, it can be implemented by welding a portal frame to form a stable support structure. The portal shape is a geometric shape similar to the word "door" formed by the top horizontal part and the two vertical parts of the second connecting frame 21. Specifically, it can be implemented by bending metal profiles or assembling segmented components to enhance structural rigidity and distribute the force.

[0065] Specifically, the handheld lever 22 is rigidly connected to the crossbar 11 via the U-shaped second connecting frame 21. During operation, the operator grips the handheld lever 22 and applies a pushing force, which is transmitted to the crossbar 11 through the U-shaped second connecting frame 21, causing the entire laying pole 1 to move. The two side columns of the U-shaped structure form a stable support with the crossbar 11, preventing deformation caused by uneven stress.

[0066] As a more preferred implementation method, such as Figure 1-3 As shown, the second connecting frame 21 is equipped with an anti-sway mechanism 4 to prevent the waterproof cloth from swaying.

[0067] The anti-sway mechanism 4 includes a clamping plate 41, a connecting rod 42, an elastic element 43, and a lifting handle 44. One end of the connecting rod 42 is fixedly provided with the lifting handle 44, and the other end of the connecting rod 42 passes through the crossbar 11 and is fixedly connected to the clamping plate 41. A pull rod is also provided in the radial direction of the connecting rod 42. One end of the elastic element 43 is connected to the pull rod, and the other end is connected to the crossbar 11.

[0068] The clamping piece 41 is a structure used to clamp and fix the waterproof fabric roll. It can be made of metal or plastic and restricts the displacement of the waterproof fabric in all directions by clamping and pressing.

[0069] Link 42 is a rigid rod that connects the lifting handle 44 and the clamping plate 41. It can be made of stainless steel tube or aluminum alloy rod and is used to convert the manual lifting action into the vertical movement of the clamping plate 41.

[0070] The elastic element 43 is an elastic element that provides a restoring force. Specifically, it can be implemented by using a helical spring or elastic rubber. Through elastic deformation, the clamping piece 41 maintains contact with the waterproof fabric roll without external force, thereby preventing the waterproof fabric roll from moving back and forth.

[0071] The tension rod is a transverse rod extending perpendicular to the connecting rod 42. Specifically, it can be connected to the connecting rod 42 by welding and is used to evenly transmit the tension of the elastic element 43 to the axial direction of the connecting rod 42.

[0072] Specifically, the anti-sway mechanism 4 operates as follows: when the lifting handle 44 is operated, the connecting rod 42 drives the clamping piece 41 to move vertically, at which time the elastic element 43 is compressed or stretched; when the external force is released, the rebound force of the elastic element 43 acts on the connecting rod 42 through the pull rod, causing the clamping piece 41 to automatically reset and press the waterproof cloth. During the laying process, the clamping piece 41 continuously applies lateral restraint force, which can effectively suppress the swaying of the waterproof cloth caused by wind or movement inertia.

[0073] In some embodiments, the preload of the elastic element 43 is adjustable, for example, by changing the initial compression of the spring to accommodate the clamping requirements of waterproof fabrics of different thicknesses. The working surface of the clamping piece 41 may be provided with anti-slip textures, such as transverse grooves or raised particles, to enhance the friction against the waterproof fabric.

[0074] Compared with existing technologies, current waterproof fabric laying devices lack an active anti-sway structure, which can easily lead to laying deviation or wrinkles in windy environments, requiring frequent manual adjustments. This embodiment, through the synergistic action of the clamping plate 41 and the elastic element 43, dynamically constrains the waterproof fabric during the laying process, significantly improving laying stability and reducing external environmental interference.

[0075] In addition, such as Figure 1-3 As shown, the column of the second connecting frame 21 is telescopic.

[0076] Telescopic columns are height-adjustable support structures, typically achieved using sleeve-type telescopic rods secured at different heights by locking bolts or spring clips. This structure allows for adjustment of the overall device height to accommodate different construction workers, improving operational adaptability.

[0077] See also Figures 1-3As shown, a limiting rod 211 is fixedly installed inside the second connecting frame 21. The limiting rod 211 is perpendicular to the column, and the connecting rod 42 passes through the limiting rod 211.

[0078] The limiting rod 211 is a transverse guide component fixed inside the second connecting frame 21, and can be formed by welding a round or square metal rod. The limiting rod 211 forms a sliding fit with the connecting rod 42, limiting the displacement of the connecting rod 42 during movement and ensuring that the clamping piece 41 and the contact surface of the waterproof cloth remain perpendicular.

[0079] Specifically, when the operator pulls the handle 44 to perform a clamping action, the connecting rod 42 moves along the axis perpendicular to the limit rod 211 to prevent the connecting rod 42 from swaying radially.
