Description

Technical Field

[0001] This utility model relates to the field of prestressed construction technology in building engineering, and in particular to a prefabricated roof waterproof connection structure. Background Technology

[0002] Precast roofs refer to roof structures that are manufactured and processed in factories or prefabrication sites and then transported to the construction site for assembly. This method improves the efficiency and quality of construction through standardized production. Since roofs are often exposed to the external environment and affected by weather factors such as rain and snow, precast roofs need to use waterproof connection structures. Waterproof connection structures can ensure that the joints of various parts of the roof are not prone to leakage, avoiding structural damage, damage to internal facilities, or mold growth caused by water seepage. The benefits of using waterproof connection structures include enhancing the durability of the roof, extending its service life, improving the living comfort and safety of the building, and reducing later maintenance costs.

[0003] The working principle of existing prefabricated roof waterproof connection structures mainly relies on multi-layer waterproof design and joint sealing technology. First, a layer of waterproof material, such as a waterproof membrane or waterproof coating, is applied during the manufacturing process of the prefabricated roof to ensure that the roof surface is waterproof. At the joints, sealing strips, welding, or overlapping are used to prevent water from seeping through the joints. In addition, the waterproof layer covers the entire roof, including all perforations and joints, forming a continuous waterproof barrier. The roof is also equipped with a drainage system to ensure that water can be drained quickly and to prevent water accumulation and seepage. Finally, a protective layer is covered on the waterproof layer to prevent external damage or the effects of ultraviolet rays. In summary, prefabricated roof waterproof connection structures, through multi-layer waterproof design, joint sealing, continuous waterproof membrane, and drainage system, ensure the waterproof performance of the roof, prevent water penetration, and thus improve the durability of the roof and the comfort of the building.

[0004] The existing technical solutions have the following drawbacks: the existing prefabricated roof structure is prone to water seepage or even leakage due to long-term rain erosion, which greatly reduces the service life of the prefabricated roof. Moreover, due to the complex splicing and installation structure of the prefabricated roof, it is difficult to complete the splicing and installation of the prefabricated roof in a short time. Therefore, a prefabricated roof waterproof connection structure is proposed to solve the above problems. Utility Model Content

A sliding groove is opened on the top of the waterproof membrane 1, and the horizontal splicing plate 2 is slidably connected in the sliding groove.

[0030] The waterproof membrane 1 includes a waterproof coating 15, which is an important component of the surface of the waterproof membrane 1 and serves to prevent water penetration. The coating can be made of waterproof paint, such as polyurethane. The waterproof coating 15 is fixedly connected to the top layer of the waterproof membrane 1. A coated steel plate 16 is fixedly connected to the bottom of the waterproof coating 15. The function of the coated steel plate 16 is to enhance the structural stability of the waterproof membrane 1 and prevent the coating from peeling off due to external forces or climate changes. Two sound insulation layers 17 are fixedly connected to the bottom of the coated steel plate 16. A heat insulation layer 19 is fixedly connected to the side of the two sound insulation layers 17 that are close to each other. The sound insulation layer 17 is mainly used to reduce the impact of noise such as raindrops on the interior of the building, while the heat insulation layer 19 helps to reduce the conduction of heat from the roof and maintain a stable indoor temperature. A waterproof base plate 18 is fixedly connected to the bottom of the sound insulation layer 17. The waterproof base plate 18 is located at the bottom of the waterproof membrane 1 and provides additional waterproof protection to prevent water from penetrating downwards and protect the building structure from moisture damage.

[0031] Reference Figure 2 , Figure 5 The waterproofing mechanism includes a water-guiding block 13, which is fixed to the right side of the waterproofing membrane 1. The water-guiding block 13 guides water flow towards one side of the roof, preventing water from seeping into the joints.

The position of the sliding block can be adjusted by pushing the push button 9, ensuring that protection is provided without affecting subsequent maintenance. The top of the 3 is fixedly connected with a protective groove 6. The design of the protective groove 6 can provide protection for the water guide block 13 and prevent external factors from damaging the water guide block 13 or affecting its normal function. The sliding block 7 is slidably connected inside the protective groove 6. The top of the water guide block 13 is detachably connected with multiple fixing screws 10. The fixing screws 10 are detachably connected through external threads. At the same time, the fixing screws 10 ensure the stability of the splicing mechanism connection. The interior of the longitudinal splicing plate 11 3 and the longitudinal splicing plate 2 4 are provided with multiple screw holes 5. The multiple screw holes 5 correspond to the water guide block 13. The water guide block 13 is detachably connected in the screw holes 5.

[0033] Working principle: The waterproof membrane 1 is horizontally spliced ​​by the horizontal splicing plate 2 located at the bottom of the waterproof membrane 1. Then, the waterproof membrane 1 is vertically spliced ​​with the assistance of the vertical splicing plate 3 and the vertical splicing plate 4 on both sides of the waterproof membrane 1. During the vertical splicing process, a groove is formed between the splicing groove 11 and the splicing groove 22 to provide support for the splicing of the vertical splicing plate 3. At the same time, a groove is formed between the splicing groove 22 and the waterproof splicing groove 14 to provide support for the vertical splicing plate 24. Then, the fixing screw 10 provides additional support for the vertical splicing to prevent the phenomenon of falling off.

[0034] During use, the water guide block 13 provides guidance for water flow. Meanwhile, the protective groove 6 and the limiting groove 8 on the top of the water guide block 13 provide the sliding position and angle for the sliding block 7. The sliding block 7 provides waterproof protection for the water guide block 13 and the fixing screw 10, thereby reducing the difficulty of later maintenance. The push button 9 on the top of the sliding block 7 reduces the difficulty of pushing the sliding block 7 to slide.

[0035] The top waterproof coating 15 of the waterproof board 1 provides a waterproof layer to prevent water from penetrating the waterproof board 1. Then, the coated steel plate 16 at the bottom of the waterproof coating 15 provides a skeleton support for the waterproof board 1. Then, the sound insulation layer 17 and heat insulation layer 19 at the bottom of the coated steel plate 16 provide sound insulation and heat insulation protection, thereby improving the heat preservation effect. Finally, the waterproof base plate 18 at the bottom of the waterproof board 1 provides the final waterproof effect, thereby further improving the practicality of the device.
