[0002] To fully develop and utilize underground space, single-story or multi-story basements are often considered during the renovation of residential buildings, industrial parks, public buildings, and old communities. To prevent rainwater and groundwater infiltration, waterproof membranes need to be laid on the exterior walls of the basement. Traditional construction methods require scaffolding, applying a treatment agent to the base layer before laying the membrane, and heating the membrane surface with fire during installation. This method not only relies heavily on manual labor, resulting in high labor intensity, high construction costs, and low efficiency, but also makes it difficult to control the quality of manual waterproof membrane installation, and poses significant safety hazards for workers performing tasks at heights and using open flames.

The roller brush is partially embedded in the strip-shaped discharge port.

[0008] A heated guide roller is rotatably connected to one side of the support frame and gap-fitted with the roller brush. The outer edge of the heated guide roller extends out of the support frame and is used to heat, guide, and roll the waterproof membrane extending from the membrane mounting groove.

[0009] Furthermore, it also includes a secondary pressure roller and a movable support, the movable support being movably connected to the load-bearing frame; the secondary pressure roller is rotatably connected to the end of the movable support away from the load-bearing frame, and can move closer to or further away from the load-bearing frame under the drive of the movable support.

[0010] Furthermore, the movable support includes an elastic element, a sliding element, and a limiting element connected sequentially from top to bottom; the two ends of the elastic element are respectively connected to the load-bearing frame and the sliding element; one end of the sliding element is hinged to the load-bearing frame, and the other end is rotatably connected to the secondary pressure roller, and a slider is provided in the middle of the sliding element; one end of the limiting element is fixed to the load-bearing frame, and the other end is provided with a groove that slides with the slider.

[0011] Furthermore, the roll installation groove is rotatably equipped with an auxiliary roller, which is in rolling connection with the waterproof roll.

[0012] Furthermore, a heating rod is provided at the bottom of the waterproof coating box.

[0013] Furthermore, the load-bearing frame includes side frames and limiting crossbars, and the two side frames are connected by a plurality of limiting crossbars to form the roll material mounting groove and the paint mounting groove; the auxiliary roller is rotatably connected to the limiting crossbars.

[0015] Furthermore, the load-bearing frame has a structure that is narrower at the top and wider at the bottom, and the load-bearing frame narrows on the side away from the heating guide roller in the direction above the heating guide roller; the traction rope is connected to the top end of the load-bearing frame away from the heating guide roller in a direction inclined to the wall.

[0016] Furthermore, the support frame also includes an upper support leg, a telescopic rod, and a lower support leg, with the upper support leg and the lower support leg connected by the telescopic rod; the upper support leg is a portal frame structure used for support against the wall; the lower support leg is used to connect to the ground; the traction mechanism is located on the telescopic rod and includes a power disc, a guide wheel, and a traction rope, with one end of the traction rope wrapped around the power disc and the other end passing over the guide wheel at the top of the telescopic rod and then connected to the load-bearing frame.

Detailed Implementation

[0027] The embodiments of this utility model will now be described with reference to the accompanying drawings.

[0028] This utility model provides an external wall waterproof membrane construction device for laying waterproof membrane on external walls. Compared with the existing technology, which requires scaffolding to be erected first, a treatment agent to be applied to the wall base before laying the membrane, and the membrane to be heated by fire during laying, the external wall waterproof membrane construction device of this application eliminates the need for scaffolding. The waterproof coating can be directly applied to the laying surface of the waterproof membrane, and the membrane can be heated to a set temperature before being laid on the wall. This effectively reduces the workload and operation difficulty for workers, improves the laying quality and construction efficiency, avoids working at heights and open flames, and enhances operational safety.

[0029] like Figures 1 to 4 As shown, this utility model embodiment proposes an external wall waterproof membrane construction device, including a load-bearing frame 1 and a support frame 8. The support frame 8 is equipped with a traction mechanism 81, which is connected to the load-bearing frame 1 via a traction rope 813, and is used to drive the load-bearing frame 1 to be lifted along the wall 9; the load-bearing frame 1 includes:

[0030] The roll installation groove 13 is located at the bottom of the load-bearing frame 1 and is used to place the roll of waterproof membrane 10.

[0031] The paint installation groove 14 is set at the top of the load-bearing frame 1. A waterproof paint box 2 is provided inside the groove. A strip-shaped discharge port is provided at the bottom of the waterproof paint box 2. A roller brush 4 is rotatably installed at the strip-shaped discharge port. The roller brush 4 is partially embedded in the strip-shaped discharge port.

[0032] The heating guide roller 3 is rotatably connected to one side of the support frame 1 and is in clearance fit with the roller brush 4. The outer edge of the heating guide roller 3 extends out of the support frame 1 and is used to heat, guide and roll the waterproof membrane 10 that extends from the membrane installation groove 13.

[0033] Through the above technical solution, the rolled waterproof membrane 10 can be placed in the membrane installation groove 13 of the load-bearing frame 1. Its free end extends to the side of the load-bearing frame 1 near the wall 9 after passing through the gap between the heating guide roller 3 and the roller brush 4. During this process, the waterproof membrane 10 simultaneously contacts the heating guide roller 3 and the roller brush 4, driving the roller brush 4 to rotate, so that the waterproof coating on the roller brush 4 is evenly coated on the laying surface of the waterproof membrane 10. At the same time, the heating guide roller 3 heats the waterproof membrane 10 to the set temperature that meets the laying requirements. By fixing the support frame 8 to the wall 9 and controlling the traction mechanism 81 on the support frame 8 to lift the load-bearing frame 1 through the traction rope 813, the heating guide roller 3 applies lateral pressure to the waterproof membrane 10 during the lifting process, so that the waterproof membrane 10 is tightly laid on the wall 9 while continuously extending upward. The whole process can be completed by only one person, realizing the rapid and high-quality laying of the waterproof membrane 10, eliminating the need for scaffolding erection, manual application of waterproof coating and open flame operations, significantly improving construction efficiency and reducing safety hazards.

[0034] In the above embodiments, the roll installation groove 13 is adapted to the shape and size of the rolled waterproof roll 10, and can stably support the waterproof roll 10 to ensure that it remains stable during the unwinding process.

[0035] The aforementioned paint installation groove 14 is positioned above the roll material installation groove 13, and a waterproof paint box 2 is installed inside it. To ensure that the waterproof paint can be evenly applied across the entire width of the waterproof roll material 10, the length of the strip-shaped outlet and the length of the rolling brush of the waterproof paint box 2 are adapted to the width of the waterproof roll material 10. Preferably, the waterproof strip box is detachably installed within the paint installation groove 14, and different waterproof paint boxes 2 can be selectively installed as needed to adapt to different widths of the waterproof roll material 10. The waterproof paint box 2 contains waterproof paint, and for easy addition of waterproof paint, in a specific embodiment... In this example, the waterproof coating box 2 adopts a rectangular cavity structure with an open top; the strip-shaped outlet is located at the bottom of the waterproof coating box 2 and has a flow rate adjustment function, which can adjust the flow rate of waterproof coating flowing out of the strip-shaped outlet as needed; the roller brush 4 is a matching product of the waterproof coating box 2. Preferably, the roller brush 4 is detachably mounted on the waterproof coating box 2. The roller brush 4 and the waterproof coating box 2 can adopt a shaft hole connection structure or other connection methods, as long as the roller brush 4 can rotate axially at the strip-shaped outlet. The connection method is common in the prior art and will not be described in detail here. Through the axial rotation of the roller brush 4, it can continuously pick up the waterproof coating in the waterproof coating box 2 and transfer it to the outside to coat the surface of the waterproof membrane 10.

[0036] It should be noted that in this embodiment, the heating guide roller 3 can rotate axially relative to the support frame 1 around its rotation axis. The direction of its rotation axis is parallel to the rotation axis of the roller brush 4, and both are parallel to the width direction of the waterproof membrane 10. When placing the waterproof membrane 10, the extended surface of the waterproof membrane 10 faces the roller brush 4. After its free end passes through the gap between the heating guide roller 3 and the roller brush 4, it passes around the heating guide roller 3, at which point the surface faces the outside of the support frame 1. By precisely setting the position of the heating guide roller 3 so that its outer edge extends out of the support frame 1, it is ensured that the heating guide roller 3 can press the waterproof membrane 10 against the wall 9, realizing the rolling function of the heating guide roller 3. At the same time, the heating guide roller 3 also has a heating function. Specifically, the heating guide roller 3 can use electric heating to heat and soften the waterproof membrane 10, so that it can better bond with the waterproof coating and adhere tightly to the wall 9.

[0037] In this embodiment, the gap between the heating guide roller 3 and the roller brush 4 is set according to the thickness of the waterproof membrane 10. The gap is not greater than the thickness of the waterproof membrane 10 and should not be too small, so as not to affect the smooth passage of the waterproof membrane 10.

[0038] In this embodiment, there is sufficient space between the heating guide roller 3 and the roll material mounting groove 13 so that the waterproof roll material 10 can extend from the roll material mounting groove 13 toward the heating guide roller 3.

[0039] Furthermore, in the embodiments of this application, such as Figure 1 , Figure 2 As shown, the exterior wall waterproof membrane construction device in this application also includes a secondary pressure roller 5 and a movable support 6. The movable support 6 is movably connected to the load-bearing frame 1. The secondary pressure roller 5 is rotatably connected to the end of the movable support 6 away from the load-bearing frame 1, and can move closer to or away from the load-bearing frame 1 under the drive of the movable support 6. The part of the waterproof membrane 10 after passing over the heating guide roller 3 is the section to be laid. The secondary pressure roller 5 is located between the section to be laid and the load-bearing frame 1, and is rolled and connected with the section to be laid. By setting the secondary pressure roller 5, it can cooperate with the heating guide roller 3 to make the laying of the waterproof membrane 10 more uniform and dense. Specifically, after the heating guide roller 3 lays the waterproof membrane 10 on the wall 9, as the load-bearing frame 1 is lifted, the secondary pressure roller 5 rolls the waterproof membrane 10 again to ensure the laying quality of the waterproof membrane 10. At the same time, the secondary pressure roller 5 is set at the end of the movable support 6 away from the load-bearing frame 1, and can move closer to or away from the load-bearing frame 1 under the drive of the movable support 6 to achieve the effect of waterproof membrane laying. The waterproof membrane 10 features automatic adjustment of lateral pressure. Specifically, when the wall surface is uneven or the resistance changes during installation, the secondary pressure roller 5 automatically adjusts its lateral pressure on the waterproof membrane 10 based on the reaction force from the wall, via the movable connection between the movable bracket 6 and the load-bearing frame 1. For example, when encountering a protruding part of the wall, the secondary pressure roller 5 experiences a larger reaction force, and the movable bracket 6 moves slightly away from the protruding part, thus reducing the pressure on the protruding part. Conversely, when encountering a recessed part of the wall, the secondary pressure roller 5 moves closer to the recessed part under the action of the movable bracket 6, increasing the pressure on the recessed part. Through this automatic adjustment mechanism, the secondary pressure roller 5 can always maintain a suitable contact pressure with the waterproof membrane 10, ensuring the installation quality of the waterproof membrane 10.

[0040] Furthermore, in the embodiments of this application, such as Figure 2As shown, the movable support 6 includes an elastic element 61, a sliding element 62, and a limiting element 63 connected sequentially from top to bottom; the two ends of the elastic element 61 are respectively connected to the load-bearing frame 1 and the sliding element 62; one end of the sliding element 62 is hinged to the load-bearing frame 1, and the other end is rotatably connected to the secondary pressure roller 5, and a slider is provided in the middle of the sliding element 62; one end of the limiting element 63 is fixed to the load-bearing frame 1, and the other end is provided with a groove that slides with the slider. Through the above technical solution, when the secondary pressure roller 5 is subjected to different reaction forces from the wall 9, the limiting member 63 rotates along its hinge point with the load-bearing frame 1, and under the action of the elastic member 61, the slider slides along the groove within a set range to move closer to or away from the wall 9. Specifically, one end of the limiting member 63 is connected to the load-bearing frame 1, and the other end extends obliquely upward to the outside of the load-bearing frame 1. Its end is provided with an arc-shaped groove, and the slider of the sliding member 62 can slide automatically along the arc-shaped groove. When the secondary pressure roller 5 is subjected to a large reaction force from the wall 9, the secondary pressure roller 5 slides towards the side closer to the load-bearing frame 1 and away from the wall 9 through the sliding member 62. When the secondary pressure roller 5 is subjected to a small reaction force from the wall 9, the sliding member 62 slides towards the side closer to the wall 9 and away from the load-bearing frame 1 under the drive of the elastic member 61.

[0041] Furthermore, in the embodiments of this application, such as Figure 2 As shown, the roll installation groove 13 is rotatably equipped with an auxiliary roller 7, which is rotatably connected to the waterproof roll 10. In actual work, the waterproof roll 10 is generally rolled up. By stretching its automatic end, it can be rotated in the roll installation groove 13. By setting the auxiliary roller 7, the frictional resistance of the waterproof roll 10 when it rotates in the roll installation groove 13 can be reduced, so that the waterproof roll 10 can be evenly and continuously unrolled and laid on the wall 9.

[0042] Furthermore, in the embodiments of this application, such as Figure 3 As shown, a heating rod 21 is provided at the bottom of the paint box. Specifically, the heating rod 21 uses electric heating, and the heating temperature can be adjusted by voltage to maintain the waterproof paint in the waterproof paint box 2 at the set temperature, ensuring the coating quality of the waterproof paint. Furthermore, the heating guide roller 3 also uses electric heating, which keeps the waterproof membrane 10 at a suitable laying temperature, thus replacing the traditional flame heating method and improving the safety of the waterproof membrane 10 laying operation. By setting up the heating rod 21 and the heating guide roller 3, the heating and coating of the waterproof paint and the heating and laying of the waterproof membrane 10 are effectively integrated, significantly reducing the labor difficulty and workload, and improving construction efficiency.

[0043] Furthermore, in the embodiments of this application, such as Figure 2As shown, the load-bearing frame 1 includes a side frame 11 and a limiting crossbar 12. The two side frames 11 are connected by several limiting crossbars 12 to form a roll material installation groove 13 and a paint installation groove 14. The auxiliary roller 7 is rotatably connected to the limiting crossbar 12. Specifically, the limiting crossbars 12 are respectively connected to the top of the side frame 11 and both sides of the top width square, forming a roll material installation groove 13 and a paint installation groove 14. At least four limiting crossbars 12 are included, wherein at least one limiting crossbar 12 corresponding to the roll material installation groove 13 is provided with an auxiliary roller 7, and the size of the space enclosed by the auxiliary roller 7 is adapted to the shape of the waterproof roll material 10. Preferably, the cross section of the limiting crossbar 12 forming the roll material installation groove 13 is circular to facilitate the installation of the auxiliary roller 7. The auxiliary roller 7 can be arranged along the length of the limiting crossbar 12, or multiple rollers can be evenly distributed along the length of the limiting crossbar 12. The cross section of the limiting crossbar 12 corresponding to the paint installation groove 14 can be set to square or circular as needed, both of which can be adapted to the shape of the waterproof paint box 2. Preferably, the limiting crossbar 12 corresponding to the paint installation groove 14 is engaged with the waterproof paint box 2, so that the waterproof paint box 2 can be detachably and stably installed in the paint installation groove 14.

[0044] Based on the above embodiments, preferably, the limiting crossbar 12 includes several detachably connected pipe segments, with adjacent pipe segments connected by bolts. By selectively setting the number of pipe segments of the limiting crossbar 12, the distance between the two side frames 11 can be controlled to form roll material installation grooves 13 and paint installation grooves 14 of different lengths, adapting to the laying requirements of waterproof roll materials 10 of different widths, thus improving the applicability of the device.

[0045] Furthermore, in the embodiments of this application, such as Figure 2 , Figure 3 As shown, the support frame 1 has a structure that is narrow at the top and wide at the bottom. The support frame 1 narrows on the side away from the heating guide roller 3. The traction rope 813 is connected to the top of the support frame 1 away from the heating guide roller 3 along the direction inclined to the wall 9. With the above arrangement, the pulling direction of the traction mechanism 81 forms a certain angle with the gravity direction of the support frame 1, so that the support frame 1 is inclined against the side of the wall 9. By reasonably setting the inclination angle and the movement range of the secondary pressure roller 5, the support frame 1 can form a certain lateral pressure on the wall surface under the action of the pulling force of the traction mechanism 81. The heating guide roller 3 and the secondary pressure roller 5 can apply sufficient lateral pressure to the waterproof membrane 10 and lay it more tightly on the wall 9.

[0046] In one alternative technical solution of the above embodiment, the side frame 11 is a frame structure that is narrow at the top and wide at the bottom. The load-bearing frame 1 is provided with a paint installation groove 14 on the side above the heating guide roller 3 away from the heating guide roller 3. The narrowing width of the load-bearing frame 1 is adapted to the set tilt angle to ensure that the heating guide roller 3 can abut against the wall 9 through the waterproof membrane 10 at the tilt angle. The traction rope 813 is connected to the limiting crossbar 12 at the top of the paint installation groove 14 away from the heating guide roller 3.

[0047] Furthermore, in the embodiments of this application, such as Figure 4 As shown, the support frame 8 also includes an upper support leg 82, a telescopic rod 83, and a lower support leg 84. The upper support leg 82 and the lower support leg 84 are connected by the telescopic rod 83. The upper support leg 82 is a portal frame structure used for mounting on the wall 9. The lower support leg 84 is used to connect to the ground. The traction mechanism 81 is set on the telescopic rod 83 and includes a power disc 811, a guide wheel 812, and a traction rope 813. One end of the traction rope 813 is wrapped around the power disc 811, and the other end passes around the guide wheel 812 at the top of the telescopic rod 83 and is connected to the load-bearing frame 1. Specifically, the telescopic rod 83 includes several telescopic joints, which can be extended or retracted as needed to ensure the length of the telescopic rod 83 meets usage requirements; the power disc 811 is fixed to one end of the telescopic rod 83 near the lower support leg 84, and can be an electric winch or a manual winch; the guide wheel 812 is set in a position that does not affect the telescopic function of the telescopic rod 83, such as the connection between the top of the telescopic rod 83 and the upper support leg 82, so that the traction rope 813 between the topmost guide wheel 812 and the load-bearing frame 1 can extend in the direction inclined to the wall 9; in use, the bottom end of the upper support leg 82 rests on the top surface of the wall 9, the topmost guide wheel 812 is located above the wall 9, and the telescopic rod... 83 extends from top to bottom along the direction inclined to the wall 9, so that the lower support leg 84 contacts and connects with the ground, thereby fixing the support frame 8; preferably, in order to ensure that the lower support leg 84 has sufficient contact area with the ground and prevent it from sliding during use, the lower support leg 84 is a pipe set perpendicular to the wall 9; through the above technical solution, the support frame 8 can be installed conveniently and quickly, and the load-bearing frame 1 can be stably suspended on one side of the wall 9, and then the waterproof membrane 10 can be constructed by lifting the load-bearing frame 1; at the same time, the position of the support frame 8 can be quickly moved to the next construction site after the construction of one part of the wall 9 is completed, which can be completed by a single person, and is simple and easy to operate.

[0048] This application also proposes a method for constructing an exterior wall waterproof membrane using the aforementioned exterior wall waterproof membrane construction device, comprising the following steps:

[0049] S1. Erect a support frame 8 on the top of the wall 9 to be constructed, and adjust the length of the telescopic rod 83 so that its other end is stably fixed on the ground.

[0050] In this embodiment, the telescopic rod 83 has a locking function and can lock itself after the length adjustment is completed; the telescopic rod 83 has a set tilt angle so that the upper support leg 82 and the lower support leg 84 are staggered in the vertical direction and fixed to the top of the wall 9 and the ground respectively.

[0051] S2. Place the load-bearing frame 1 outside the proposed construction site and connect the load-bearing frame 1 with the traction rope 813.

[0052] Specifically, the length of the traction rope 813 is adjusted by the power disc 811 so that it can be connected to the load-bearing frame 1 on the ground;

[0053] S3. Place the waterproof membrane 10 in the membrane installation groove 13, place the waterproof coating box 2 in the waterproof coating tank, and preheat the guide roller 3 and heating rod 21.

[0054] Specifically, the heating guide roller 3 and the heating rod 21 are heated to a set temperature and maintained.

[0055] S4. The free end of the traction waterproof membrane 10 passes around the heated guide roller 3 and extends vertically to the ground;

[0056] It is understandable that when the load-bearing frame 1 is placed on the ground, the length of the waterproof membrane 10 extending vertically to the ground is the initial length of the waterproof membrane 10 to be laid on the bottom of the wall 9.

[0057] S5. Apply waterproof coating manually to the bottom of wall 9, with the coating height being the same as the initial section length of waterproof membrane 10;

[0058] S6. Control the traction rope 813 to tighten, so that the heated guide roller 3 and the secondary pressure roller 5 abut against the waterproof membrane 10 at the bottom of the wall 9;

[0059] When the traction rope 813 lifts the load-bearing frame 1 off the ground, the load-bearing frame 1, under the action of the pulling force, presses against the wall through the waterproof membrane 10, thereby pressing the waterproof membrane 10 against the wall through the heated guide roller 3 and the secondary pressure roller 5, so that the initial section of the waterproof membrane 10 is laid on the wall 9.

[0060] S7. Run the traction mechanism 81 to lay the waterproof membrane 10 within the set width range from bottom to top;

[0061] Under the action of the traction mechanism 81, the load-bearing frame 1 moves slowly from bottom to top, and the waterproof membrane 10 rotates and unrolls continuously. After being rolled by the heated guide roller 3 and the secondary pressure roller 5, it is laid on the wall 9 within the entire height range, so as to achieve a tight fit between the waterproof membrane 10 and the wall 9.

[0062] S8, move the support frame 8 and the load-bearing frame 1 to the next construction site, and repeat the above steps to complete the laying of the waterproof membrane 10 in the entire range of the wall 9.

[0063] Specifically, after the waterproof membrane 10 is laid to the top of the wall 9 within the set width range, the waterproof membrane 10 is manually cut off, and the support frame 8 and load-bearing frame 1 are moved to the next construction site. The above steps are repeated to lay the waterproof membrane 10 of the set width again until the entire width and height range of the wall 9 is covered with waterproof membrane 10 according to the set requirements, thus completing the construction of the waterproof membrane 10 of the wall 9.

[0064] The advantages and positive effects of this utility model are:

[0065] (1) By setting up support frames and load-bearing frames, the load-bearing frames can be lifted by a traction mechanism, and waterproof membrane can be laid during the lifting process, which eliminates the scaffolding erection process, reduces construction costs, and improves construction efficiency.

[0066] (2) By setting up a roll installation groove, a paint installation groove, a roller brush and a heating guide roller, the waterproof paint can be evenly applied to the surface of the waterproof roll before it is laid. At the same time, the waterproof roll and the waterproof paint are heated to the set temperature that meets the laying requirements by using the heating guide roller and the heating rod. This not only avoids open flame operations, but also effectively integrates the application of waterproof paint with the laying of waterproof roll, which significantly reduces the difficulty and workload of labor and further improves the construction efficiency.

[0067] (3) By setting up heated guide rollers and secondary pressure rollers, the waterproof membrane undergoes two rolling operations, ensuring that the waterproof membrane adheres tightly to the wall and improving the laying quality of the waterproof membrane.

[0068] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made in accordance with the claims of this utility model should still fall within the patent coverage of this utility model.
