Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction, specifically to a compaction device for waterproof membrane compaction in green roofs to prevent edge curling. Background Technology
[0002] A green roof is a roof where planting soil is laid on the waterproof layer of a building's roof or the top slab of an underground project, and plants are planted on it to achieve waterproofing, heat preservation, heat insulation, and ecological environmental protection.
[0003] Before planting, a waterproof layer must be laid on the roof. The waterproof layer is mostly made of asphalt and waterproof cloth. During the laying process, the melted asphalt acts as an adhesive, and the waterproof cloth is also sprayed with a blowtorch to make its outer surface sticky. The two work together to complete the waterproofing of the roof.
[0004] However, after the waterproofing is laid, due to prolonged exposure to the elements and the influence of weather and environment, some parts of the waterproofing fabric may develop curling edges. If this is not addressed, rainwater will accumulate along the curled edges during the rainy season, slowly seeping in and affecting the overall waterproofing effect and reducing the overall service life.
[0005] Therefore, a practical and easy-to-install anti-warping compaction structure is needed. Utility Model Content
[0006] To address the aforementioned problems, this utility model provides a compaction device for waterproof membrane compaction in green roofs to prevent edge curling.
[0007] This utility model is achieved through the following technical solution:
[0008] A compaction device for waterproof membrane on green roofs to prevent edge curling includes a fixed frame, which is generally inverted U-shaped. A friction block is fixedly installed on one side of the fixed frame, and a pressing block, which is T-shaped, is set inside the fixed frame. An adjusting screw is screwed onto the fixed frame, one end of which is rotatably connected to the side wall of the pressing block. A rotating disk is rotatably connected to one side of the adjusting screw. A spring cylinder is fixedly installed on the inner wall of the fixed frame, and a T-shaped slide rod is slidably connected inside the spring cylinder. A first spring is set inside the spring cylinder, and one end of the T-shaped slide rod is fixedly connected to the side wall of the rotating disk. T-shaped grooves are respectively set on both sides of the pressing block, and a second spring is set inside the T-shaped groove. A T-shaped slider is slidably connected inside the T-shaped groove. An insertion frame is fixedly installed on the side wall of each T-shaped slider. Several splicing plates are inserted between two adjacent insertion frames, and a rubber pressure strip is fixedly installed on one side of each splicing plate.
[0009] Preferably, a limiting block is fixedly installed on one side of the splicing plate, and a limiting groove is provided on the other side of the splicing plate. Each limiting block is inserted into the corresponding limiting groove and slidably connected thereto. Each limiting block is covered with an extruded rubber layer.
[0010] Preferably, multiple pressure bars are fixedly installed on one side of the splicing plate. Each pressure bar consists of two L-shaped bars, one of which is made of steel and the other is made of soft rubber.
[0011] Compared with existing technologies, the advantages of this utility model are: the device is equipped with a spring cylinder, which uses the first spring inside to ensure that the adjusting screw is kept stably locked, avoiding loosening due to external factors and causing safety hazards. At the same time, it is easy to install and simple to use. The use of several splicing plates makes it easy for operators to control the distance. The installation of several pressure rods can ensure that the pressing is carried out normally and avoid the situation of insufficient compaction due to defects in the waterproof layer.

Detailed Implementation
[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:
[0017] like Figure 1 , Figure 2 , Figure 3As shown, a compaction device for waterproof membrane on green roofs to prevent edge curling includes a fixing frame 1, which is generally inverted U-shaped. A friction block 2 is fixedly installed on one side of the fixing frame 1. A pressing block 3, which is T-shaped, is provided inside the fixing frame 1. An adjusting screw 4 is screwed onto the fixing frame 1. One end of the adjusting screw 4 is rotatably connected to the side wall of the pressing block 3. A rotating disk 5 is rotatably connected to one side of the adjusting screw 4. A spring cylinder 6 is fixedly installed on the inner wall of the fixing frame 1. A T-shaped slide rod 7 is internally slidably connected. A first spring 8 is installed inside the spring cylinder 6. One end of the T-shaped slide rod 7 is fixedly connected to the side wall of the rotating disk 5. T-shaped grooves 9 are respectively provided on both sides of the clamping block 3. A second spring 10 is installed inside the T-shaped groove 9. A T-shaped slider 11 is slidably connected inside the T-shaped groove 9. A plug-in frame 12 is fixedly installed on the side wall of each T-shaped slider 11. Several splicing plates 13 are inserted between two adjacent plug-in frames 12. One side of each splicing plate 13 has A rubber pressure strip 15 is fixedly installed. During operation, the device is installed at the edge of the rooftop by the friction block 2 and the clamping block 3. The fixing frame 1 is then fastened to the edge wall. The adjusting screw 4 is rotated to ensure that the clamping block 3 is tightly fitted to the wall, thus ensuring overall fixation. A spring 6 and a first spring 8 are also provided. The elasticity of the first spring 8 is used to constantly press the adjusting screw 4 to prevent it from loosening and causing safety hazards. Several splicing plates 13 are spliced together. The appropriate splicing length is selected according to the distance between the two walls of the rooftop. After splicing, both ends are inserted into the corresponding insertion frames 12. During the insertion process, since the insertion frames 12 are close to the wall, they need to be pulled outward. This will compress the second spring 10. After installation, the elasticity of the second spring 10 can be used to press the edge of the waterproof layer, thus preventing it from warping.
[0018] A limiting block 16 is fixedly installed on one side of the splicing plate 13, and a limiting groove 17 is provided on the other side of the splicing plate 13. Each limiting block 16 is inserted into the corresponding limiting groove 17 and slidably connected with it. Each limiting block 16 is wrapped with a compression rubber layer, which allows several splicing plates 13 to be spliced. At the same time, in order to avoid the pressure, the length of several splicing plates 13 after splicing should be kept between 1m and 1.5m.
[0019] Multiple pressure rods 14 are fixedly installed on one side of the splicing plate 13. Each pressure rod 14 consists of two L-shaped rods. The L-shaped rod fixed to the splicing plate 13 is made of steel, while the other L-shaped rod is made of soft rubber. By using multiple pressure rods 14, the pressing work can be carried out over a wider range, avoiding unevenness at the ends caused by the adhesion of the waterproof cloth itself, thus completing the pressing work better.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
