Description

Technical Field

[0001] A waterproof membrane suspension construction device is disclosed, relating to the field of building construction, specifically, a construction device for waterproof membranes on basement side walls or culvert exterior walls. Background Technology

[0002] In the construction of waterproof membrane on the exterior walls of basements, a common method is to erect double-row ground-supported scaffolding on one side of the exterior wall to be waterproofed, with workers applying the waterproof membrane on the scaffolding. However, the bottom of the foundation pit on the outside of basements is generally uneven, and the soil is soft and often accompanied by water accumulation, making the erection of ground-supported scaffolding difficult and posing certain safety risks. In addition, the erection of ground-supported scaffolding requires investment in materials and labor, and it must pass inspection before it can be put into use, resulting in high costs and long time consumption. Utility Model Content

[0003] The technical problem this utility model aims to solve is to provide a device that allows for the installation of waterproof membrane on basement side walls or culvert exterior walls without the need for scaffolding, addressing the aforementioned shortcomings. The technical solution is as follows:

[0004] A waterproof membrane suspension construction device, the key technologies of which include a membrane container, a suspension device, and a pressing device, wherein the membrane container has an opening on one side, and stiffening rings are respectively set at both ends of the body, and a cross is set in the inner ring of the stiffening ring; the suspension device includes a force-bearing rod and a lifting cable, the lifting cable is respectively set at both ends of the membrane container, and the other end of the lifting cable is respectively fixed to the end of the force-bearing rod; the pressing device has a variable rod fixed at the top of the cross, a pressing roller installed at the lower end of the variable rod, a small crossbar installed between the center of the cross and the variable rod, a spring installed between the lower end of the cross and the variable rod, control ropes are provided at both ends of the pressing roller, the vertical rod of the cross extends downward to be flush with the pressing roller, and a ring is provided at the end of the vertical rod, and the other end of the control rope is threaded through the ring.

[0005] Compared with the prior art, the present invention has the following beneficial effects:

[0006] 1. The design of the roll material container, suspension device, and pressing device in this utility model enables the construction of waterproof roll material on the side walls of basements or the outer walls of culverts without the need for scaffolding. This eliminates the safety risks of ground-mounted scaffolding, saves on material and labor costs associated with erecting ground-mounted scaffolding, and completely solves the problem of high costs and long construction time associated with erecting ground-mounted scaffolding.

[0007] 2. The roll material container is a three-quarters hollow cylinder made of sheet metal. The opening is ground smooth and evenly coated with wax oil to ensure that the roll material falls smoothly and at a uniform speed during construction.

[0008] 3. The roll container has rings on both sides, and the sheet metal of the roll container is welded to the rings. The cross is fixed inside the rings to ensure that the rings do not deform. The cross is slightly thicker than the rings to facilitate the subsequent connection of the variable rod.

[0009] 4. The pressing roller is connected to the roll container via a variable rod. The variable rod is a cantilever rod with its rear end fixed to both sides of the roll container, forming a triangle with the small crossbar and the crossbar of the roll container. The front cantilever is the cantilever end, and the middle of the cantilever end is connected to the lower part of the crossbar of the roll container via a spring. The spring is in a tensioned state. The cantilever ends of the variable rods at both ends of the roll container are connected to the two ends of the pressing roller.

[0010] 5. The vertical bar of the cross-shaped container extends downwards, with the extension length being flush with the cantilever end of the variable bar. A ring is provided at the end of the extension end, and the control ropes at both ends of the pressure roller can change the direction of force through the ring to be flush with the downward direction of the device.

[0015] Reference Figures 1-3A waterproof membrane suspension construction device, the key technology of which includes a membrane container 13, a suspension device, and a pressing device. The membrane container 13 has an opening on one side, and stiffening rings 5 ​​are welded and fixed to both ends of the body. A cross 4 is welded and fixed to the inner ring of the stiffening ring 5 to prevent deformation of the stiffening ring 5. A load-bearing shaft 15 is set at the center of the cross 4. The suspension device includes a force-bearing rod 2 and a lifting cable 3. The lifting cable 3 is fixed to the load-bearing shaft 15 at both ends of the membrane container 13. The other end of the lifting cable 3 is fixed to the end of the force-bearing rod 2. A lifting ring 1 is provided at the center of the force-bearing rod 2. The lifting ring 1 is connected to other lifting devices. Fixed cables 8 are also provided on the load-bearing shafts 15 at both ends of the material container 13. The other end of the fixed cables 8 is tied to a fixed point on the ground. The pressing device is a variable rod 6 fixed at the top of the cross 4. A pressing roller 7 is installed at the lower end of the variable rod 6. A small crossbar 9 is installed between the center of the cross 4 and the variable rod 6. A spring 10 is installed between the lower end of the cross 4 and the variable rod 6. Control ropes 12 are provided at both ends of the pressing roller 7. The vertical rod of the cross 4 extends downward to be flush with the pressing roller 7. A ring 11 is provided at the end of the vertical rod. The other end of the control rope 12 is threaded through the ring 11. The ring 11 acts like a fixed pulley to change the direction of the control rope 12.

[0016] During construction, such as Figure 4 As shown, the waterproof membrane 14 is placed into the body of the membrane container 13 through the opening. The end of the waterproof membrane roll is pulled out from the opening and hangs downwards. The device is connected to other lifting devices (manual pulling or electric hoist) through the lifting ring 1, and fixed to the ground below by the fixing cable 8. The stiffening ring 5 of the membrane container 13 is kept close to the exterior wall 16 to be constructed. Since the pressing roller 7 connected to the variable rod 6 protrudes further towards the side to be constructed than the stiffening ring 5, the upper end of the variable rod 6 is fixed and the lower end is movable. Under the traction of the spring 10 (initially in a tensioned state) and the control rope 12, the movable end of the variable rod 6 deforms, so that the pressing roller 7 can firmly press the waterproof membrane 14 onto the surface of the exterior wall 16 to be constructed. As the lifting device slowly lifts the device, the waterproof membrane 14 can be uniformly pasted onto the surface of the exterior wall 16 to be constructed.

[0017] If the waterproof membrane 14 is found to be loosely adhered during construction, manually pull the control rope 12. Under the reaction force of the spring 10, the variable rod 6 will cause the pressing roller 7 to press repeatedly to ensure that the waterproof membrane 14 is firmly bonded to the exterior wall 16 to be constructed. After the waterproof membrane 14 is installed, if the exterior wall 16 to be constructed is not yet completed, the lifting device will release its force and descend. After replacing the waterproof membrane 14, place the end of the membrane on the pressing roller 7, pull the control rope 12 to actively deform the variable rod 6, ensuring that the pressing roller 7 does not contact the completed waterproof surface. When it rises to the height of the completed waterproof (ensuring the overlap length of the waterproof membrane 14), release the control rope 12 to bond the old and new waterproof membranes. Repeat the construction until the waterproof membrane of the wall to be constructed is installed to the top.
