[0036] The embodiments of the present invention are described below with reference to the accompanying drawings.

[0037] An embodiment of the present invention proposes an exterior wall waterproofing membrane construction device for laying waterproofing membranes on exterior walls. Compared with the prior art method in which a scaffolding needs to be erected first, a treatment agent needs to be applied to the wall base layer before laying the membrane, and the waterproofing membrane needs to be baked by fire during laying, the exterior wall waterproofing membrane construction device in the present application does not require the erection of a scaffolding. The waterproof coating can be directly applied to the laying surface of the waterproofing membrane, and the waterproofing membrane can be laid on the wall after being heated to a set temperature. This effectively reduces the workload and operating difficulty of workers, improves the laying quality and construction efficiency, avoids high-altitude operations and open flame operations, and improves operational safety.

[0038] like Figures 1 to 4 As shown, an embodiment of the present invention provides an exterior wall waterproofing membrane construction device, including a load-bearing frame 1 and a support frame 8. The support frame 8 is provided with a traction mechanism 81. The traction mechanism 81 is connected to the load-bearing frame 1 through 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:

[0039] The roll material installation groove 13 is provided at the bottom end of the load-bearing frame 1 and is used to place the rolled waterproof roll material 10;

[0040] A paint installation groove 14 is provided at the top of the load-bearing frame 1, and a waterproof paint box 2 is provided inside the paint installation groove 14. A strip-shaped discharge port is provided at the bottom of the waterproof paint box 2. A roller brush 4 is rotatably provided at the strip-shaped discharge port, and the roller brush 4 is partially embedded in the strip-shaped discharge port.

[0041] The heating guide roller 3 is rotatably connected to one side of the load-bearing frame 1 and is gap-fitted with the roller brush 4. The outer edge of the heating guide roller 3 extends out of the load-bearing frame 1 and is used to heat, guide and roll the waterproof roll 10 extending from the roll installation groove 13.

[0042] 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, and its free end passes through the gap between the heated guide roller 3 and the roller brush 4 and extends to the side of the load-bearing frame 1 close to the wall 9. During this process, the waterproof membrane 10 contacts the heated guide roller 3 and the roller brush 4 at the same time, and drives the roller brush 4 to rotate, so that the waterproof coating on the roller brush 4 is evenly coated on the paving surface of the waterproof membrane 10, and the heated guide roller 3 is used to heat the waterproof membrane 10 to a set temperature that meets the paving requirements; by fixing the support frame 8 on 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 heated guide roller 3 is used to apply lateral pressure to the waterproof membrane 10 during the lifting process, so that the waterproof membrane 10 is tightly paved on the wall 9 while continuously extending upward; the entire process can be completed by one person, realizing fast and high-quality paving of the waterproof membrane 10, eliminating the need for scaffolding erection, manual application of waterproof coating and open flame operation, significantly improving construction efficiency and reducing safety hazards.

[0043] In the above embodiment, the roll material installation groove 13 is adapted to the shape and size of the rolled waterproof roll material 10 and can stably support the waterproof roll material 10 to ensure that it remains stable during the unwinding process;

[0044] The above-mentioned paint installation groove 14 is arranged above the coil installation groove 13, and a waterproof paint box 2 is arranged inside it; in order to ensure that the waterproof paint can be evenly applied to the entire width of the waterproof coil 10, the length of the strip discharge port of the waterproof paint box 2 and the length of the rolling brush are adapted to the width of the waterproof coil 10; preferably, the waterproof strip box is detachably arranged in 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 coil 10; the waterproof paint is contained in the waterproof paint box 2, and in order to facilitate the addition of waterproof paint, in a specific embodiment In the example, the waterproof coating box 2 adopts a rectangular cavity structure with an upper opening; the strip discharge port is set at the bottom of the waterproof coating box 2 and has a flow regulation function, which can adjust the flow rate of the waterproof coating flowing out of the strip discharge port as needed; the roller brush 4 is a supporting product of the waterproof coating box 2. Preferably, the roller brush 4 is detachably set on the waterproof coating box 2. The roller brush 4 and the waterproof coating box 2 can adopt an axial hole connection structure or other connection methods. As long as the roller brush 4 can be axially rotated at the strip discharge port, its connection method is common in the existing technology and will not be described here. Through the axial rotation of the roller brush 4, the waterproof coating in the waterproof coating box 2 can be continuously dipped and transferred to the outside to be coated on the paving surface of the waterproof coiled material 10.

[0045] It should be noted that in this embodiment, the heated guide roller 3 is capable of axial rotation relative to the support frame 1 about its rotation axis. The direction of its rotation axis is parallel to the rotation axis of the roller brush 4 and is also parallel to the width direction of the waterproofing membrane 10. When the waterproofing membrane 10 is placed, the paving surface of the extended waterproofing membrane 10 faces the roller brush 4. When its free end passes through the gap between the heated guide roller 3 and the roller brush 4 and bypasses the heated guide roller 3, the paving surface now faces the outside of the support frame 1. By precisely positioning the heated guide roller 3 so that its outer edge extends beyond the support frame 1, the heated guide roller 3 is able to press the waterproofing membrane 10 against the wall 9, thus achieving the rolling function of the heated guide roller 3. Furthermore, the heated guide roller 3 also has a heating function. Specifically, the heated guide roller 3 can use electrical heating to heat and soften the waterproofing membrane 10, enabling it to better bond with the waterproof coating and adhere tightly to the wall 9.

[0046] In the embodiment of the present application, 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.

[0047] In the embodiment of the present application, there is sufficient space between the heating guide roller 3 and the coil installation groove 13 to facilitate the waterproof coil 10 to extend from the coil installation groove 13 toward the heating guide roller 3.

[0048] Furthermore, in the embodiments of the present application, Figure 1 、 Figure 2As shown, the exterior wall waterproofing membrane construction device in the present application also includes a secondary pressure roller 5 and a movable bracket 6. The movable bracket 6 is movably connected to the load-bearing frame 1. The secondary pressure roller 5 is rotatably connected to the end of the movable bracket 6 away from the load-bearing frame 1, and can be moved closer to or away from the load-bearing frame 1 under the drive of the movable bracket 6. The portion of the waterproofing membrane 10 after it passes the heated guide roller 3 is the intended paving section. The secondary pressure roller 5 is located between the intended paving section and the load-bearing frame 1 and is connected to the paving section in a rolling manner. By setting the secondary pressure roller 5, it can cooperate with the heated guide roller 3 to make the paving of the waterproofing membrane 10 more uniform and dense. Specifically, after the heated guide roller 3 lays the waterproofing membrane 10 on the wall 9, as the load-bearing frame 1 is lifted, the secondary pressure roller 5 rolls the waterproofing membrane 10 again to ensure the paving quality of the waterproofing membrane 10. At the same time, the secondary pressure roller 5 is set at the end of the movable bracket 6 away from the load-bearing frame 1, and can be moved closer to or away from the load-bearing frame 1 under the drive of the movable bracket 6 to achieve the waterproofing membrane 10. Automatic adjustment of the lateral pressure of the waterproofing membrane 10; specifically, when the wall surface is uneven or the resistance of the wall surface changes during the paving operation, the secondary pressure roller 5 will automatically adjust the lateral pressure applied to the waterproofing membrane 10 according to the reaction force given by the wall surface through the movable connection between the movable bracket 6 and the load-bearing frame 1. For example, when encountering a raised part of the wall surface, the secondary pressure roller 5 will be subjected to a large reaction force, and the movable bracket 6 will move slightly accordingly, causing the secondary pressure roller 5 to slightly move away from the raised part, thereby reducing the pressure on the raised part; conversely, when encountering a recessed part of the wall surface, the secondary pressure roller 5 will move 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 relatively appropriate contact pressure with the waterproofing membrane 10, ensuring the paving quality of the waterproofing membrane 10.

[0049] Furthermore, in the embodiments of the present application, Figure 2As shown, the movable bracket 6 includes an elastic member 61, a sliding member 62 and a limiting member 63 connected in sequence from top to bottom; the two ends of the elastic member 61 are respectively connected to the load-bearing frame 1 and the sliding member 62; one end of the sliding member 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 member 62; one end of the limiting member 63 is fixed to the load-bearing frame 1, and the other end is provided with a sliding groove that slides with the slider. Through the above technical scheme, when the secondary pressure roller 5 is subjected to different reaction forces from the wall 9, the limiting member 63 is prompted to rotate along the hinge point between it and the load-bearing frame 1, and under the action of the elastic member 61, the slider is caused to slide along the slide 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 upward at an angle to the outside of the load-bearing frame 1, and an arc-shaped slide groove is provided at its end, and the slider of the slide member 62 can automatically slide along the arc-shaped slide groove; when the secondary pressure roller 5 is subjected to a larger reaction force from the wall 9, the secondary pressure roller 5 slides to the side close to the load-bearing frame 1 and away from the wall 9 through the slide member 62; when the secondary pressure roller 5 is subjected to a smaller reaction force from the wall 9, the slide member 62 slides to the side close to the wall 9 and away from the load-bearing frame 1 driven by the elastic member 61.

[0050] Furthermore, in the embodiments of the present application, Figure 2 As shown, the coiled material installation groove 13 is rotatably provided with an auxiliary roller 7, and the auxiliary roller 7 is in rolling connection with the waterproof coiled material 10; because in actual work, the waterproof coiled material 10 is generally arranged in a roll, and its automatic end can be stretched to make it rotate in the coiled material installation groove 13, by providing the auxiliary roller 7, the friction resistance of the waterproof coiled material 10 when rotating in the coiled material installation groove 13 can be reduced, so that the waterproof coiled material 10 can be evenly and continuously unrolled and laid on the wall 9.

[0051] Further, in the embodiments of this application, Figure 3 As shown, a heating rod 21 is provided at the bottom of the paint box. Specifically, the heating rod 21 utilizes electrical heating, and its temperature can be adjusted via voltage, maintaining the waterproof paint within the waterproof paint box 2 at a set temperature, ensuring the quality of the waterproof paint application. Furthermore, the heating guide roller 3 also utilizes electrical heating, which maintains the waterproofing coil 10 at a suitable laying temperature, thereby replacing the traditional flame-heating method and improving the safety of the waterproofing coil 10 laying operation. By providing the heating rod 21 and the heating guide roller 3, the heating and application of the waterproofing paint and the heating and laying of the waterproofing coil 10 are effectively integrated, significantly reducing the labor difficulty and workload, and improving construction efficiency.

[0052] Further, in the embodiments of this application, Figure 2As shown, the load-bearing frame 1 includes a side frame 11 and a limiting cross bar 12 . The two side frames 11 are connected by a plurality of limiting cross bars 12 to form a coil installation groove 13 and a paint installation groove 14 ; the auxiliary roller 7 is rotatably connected to the limiting cross bar 12 . Specifically, the limiting cross bars 12 are respectively connected to the top of the side frame 11 and the two sides of the square of the top width, forming a coil installation groove 13 and a paint installation groove 14, which include at least four limiting cross bars 12, wherein at least one limiting cross bar 12 corresponding to the coil installation groove 13 is provided with an auxiliary roller 7, and the size of the space enclosed by the limiting cross bar 12 and the auxiliary roller 7 is adapted to the shape of the waterproof coil 10; preferably, the cross section of the limiting cross bar 12 forming the coil installation groove 13 is circular to facilitate the installation of the auxiliary roller 7; the auxiliary roller 7 can be arranged along the length direction of the limiting cross bar 12, or a plurality of auxiliary rollers 7 can be evenly dispersed along the length direction of the limiting cross bar 12; the cross section of the limiting cross bar 12 corresponding to the paint installation groove 14 can be set to square and circular as needed, both of which can be adapted to the shape of the waterproof paint box 2. Preferably, the limiting cross bar 12 corresponding to the paint installation groove 14 is snap-connected with the waterproof paint box 2, so that the waterproof paint box 2 can be detachably and stably arranged in the paint installation groove 14.

[0053] Based on the above embodiment, the limiting crossbar 12 preferably comprises a plurality of detachably connected pipe segments, with adjacent segments connected by bolts. By selectively adjusting the number of pipe segments in the limiting crossbar 12, the distance between the two side frames 11 can be controlled to form different lengths of the coil installation slots 13 and the paint installation slots 14, adapting to the installation requirements of waterproofing coils 10 of different widths, thereby expanding the applicability of the device.

[0054] Further, in the embodiments of this application, Figure 2 、 Figure 3 As shown, the load-bearing frame 1 has a narrow upper part and wide lower part structure, and the load-bearing frame 1 narrows on the side above the heating guide roller 3 away from the heating guide roller 3; the traction rope 813 is connected to the end of the top of the load-bearing frame 1 away from the heating guide roller 3 in a direction inclined to the wall 9; through the above arrangement, the pulling direction of the traction mechanism 81 and the gravity direction of the load-bearing frame 1 form a certain angle, so that the load-bearing frame 1 is against the side of the wall 9 at an inclined angle, and by reasonably setting the inclination angle and the moving range of the secondary pressure roller 5, the load-bearing frame 1 can form a certain lateral pressure on the wall under the action of the pulling force of the traction mechanism 81, and the heating guide roller 3 and the secondary pressure roller 5 can apply sufficient lateral pressure to the waterproof membrane 10 to lay it more tightly on the wall 9.

[0055] In an optional 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, and 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 narrowed width of the load-bearing frame 1 is adapted to the set inclination angle to ensure that the heating guide roller 3 can be pressed against the wall 9 through the waterproof membrane 10 at the inclination angle; the traction rope 813 is connected to the limiting cross bar 12 at the end of the top of the paint installation groove 14 away from the heating guide roller 3.

[0056] Further, in the embodiments of this application, Figure 4 As shown, the support frame 8 also includes an upper leg 82, a telescopic rod 83 and a lower leg 84, and the upper leg 82 and the lower leg 84 are connected by the telescopic rod 83; the upper leg 82 is a door-type structure, used to be supported on the wall 9; the lower leg 84 is used to be connected to the ground; the traction mechanism 81 is arranged on the telescopic rod 83, including a power disk 811, a guide wheel 812 and a traction rope 813, one end of the traction rope 813 is wrapped around the power disk 811, and the other end is connected to the load-bearing frame 1 after passing through the guide wheel 812 at the top of the telescopic rod 83. Specifically, the telescopic rod 83 includes several telescopic joints, which can be extended and retracted as needed to make the length of the telescopic rod 83 meet the use requirements; the power disk 811 is fixed to one end of the telescopic rod 83 close to the lower leg 84, and an electric winch or a manual winch can be used; the guide wheel 812 is set at a set position on the telescopic rod 83 that does not affect its telescopic function, such as the connection part between the top of the telescopic rod 83 and the upper leg 82, so that the traction rope 813 between the top guide wheel 812 and the load-bearing frame 1 can extend in a direction inclined to the wall 9; when in use, the bottom end of the upper leg 82 is placed on the top surface of the wall 9, the top guide wheel 812 is located above the wall 9, and the telescopic rod 83 is placed on the top surface of the wall 9. 83 extends from top to bottom in a direction inclined to the wall 9, so that the lower support leg 84 is in contact 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 to prevent it from sliding during use, the lower support leg 84 is a pipe fitting arranged 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 construction of the waterproof membrane 10 can be achieved by lifting the load-bearing frame 1; at the same time, after the construction of one part of the wall 9 is completed, the position of the support frame 8 can be quickly moved to the next intended construction part, which can be completed by one person, and is simple to use and easy to operate.

[0057] The present application also provides a method for constructing an exterior wall waterproofing membrane, which uses the above-mentioned exterior wall waterproofing membrane construction device and includes the following steps:

[0058] S1. Set up the support frame 8 on top of the wall 9 to be constructed, and adjust the length of the telescopic rod 83 so that the other end is stably fixed on the ground;

[0059] In the embodiment of the present application, the telescopic rod 83 has a locking function and can be locked automatically after the length adjustment is completed; the telescopic rod 83 has a set inclination angle, so that the upper leg 82 and the lower leg 84 are staggered in the vertical direction and fixed to the top of the wall 9 and the ground respectively;

[0060] S2, placing the load-bearing frame 1 outside the intended construction site and connecting the load-bearing frame 1 via the traction rope 813;

[0061] Specifically, the length of the traction rope 813 is adjusted through the power disc 811 so that it can be connected to the load-bearing frame 1 on the ground;

[0062] S3, place the waterproof coiled material 10 in the coiled material installation groove 13, place the waterproof coating box 2 in the waterproof coating groove, and preheat the heating guide roller 3 and the heating rod 21;

[0063] Specifically, the heating guide roller 3 and the heating rod 21 are heated to a set temperature and maintained.

[0064] S4, pulling the free end of the waterproof membrane 10 around the heated guide roller 3 and extending vertically to the ground;

[0065] 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 length of the initial section of the waterproof membrane 10 to be laid on the bottom of the wall 9 .

[0066] S5, manually apply waterproof coating to the bottom of the wall 9, the coating height is the same as the initial length of the waterproof membrane 10;

[0067] S6, control the traction rope 813 to tighten, so that the heating guide roller 3 and the secondary pressure roller 5 press against the waterproof membrane 10 at the bottom of the wall 9;

[0068] When the traction rope 813 drives the load-bearing frame 1 off the ground, the load-bearing frame 1 is pressed against the wall through the waterproof membrane 10 under the action of the pulling force, 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.

[0069] S7, operating the traction mechanism 81 to complete the laying of the waterproof membrane 10 within the set width range from bottom to top;

[0070] Under the action of the traction mechanism 81, the load-bearing frame 1 moves slowly from bottom to top, and the waterproof membrane 10 continues to rotate and unwind. After being rolled by the heated guide roller 3 and the secondary pressure roller 5, it is laid over the entire height range of the wall 9, achieving a close fit between the waterproof membrane 10 and the wall 9.

[0071] S8, move the support frame 8 and the load-bearing frame 1 to the next intended construction site, and repeat the above steps to complete the laying of the waterproof membrane 10 in the entire range of the wall 9.

[0072] 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, and the support frame 8 and the load-bearing frame 1 are moved to the next intended construction location, and the above steps are repeated to lay the waterproof membrane 10 of the set width again until the waterproof membrane 10 is laid in the entire width and height range of the wall 9 according to the set requirements, and the construction of the waterproof membrane 10 of the wall 9 is completed.

[0073] The advantages and positive effects of the present invention are:

[0074] (1) By setting up a support frame and a load-bearing frame, the load-bearing frame can be lifted by a traction mechanism, and the waterproof membrane can be laid during the lifting process, eliminating the scaffolding erection process, reducing construction costs and improving construction efficiency;

[0075] (2) By setting up the coil material installation groove, the paint installation groove, the roller brush and the heating guide roller, the waterproof paint can be evenly applied to the paving surface of the waterproof coil material before the waterproof coil material is laid. At the same time, the waterproof coil material 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 the open flame operation, but also effectively integrates the waterproof paint application and the waterproof coil material laying operation, significantly reduces the labor difficulty and workload, and further improves the construction efficiency.

[0076] (3) By setting up a heated guide roller and a secondary pressing roller, the waterproof membrane is rolled twice in succession, ensuring that the waterproof membrane is tightly attached to the wall and improving the laying quality of the waterproof membrane.

[0077] The embodiments of the present invention are described in detail above, but the contents described are only preferred embodiments of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
