Technical Field
[0001] This utility model relates to the field of architectural design technology, and in particular to a modular waterproof structure for architectural roof design. Background Technology
[0002] In building construction, roof waterproofing is a crucial aspect. Currently, there are various types of roof waterproofing structures, among which prefabricated waterproofing structures have gained some application in the construction field due to their advantages such as convenient construction and shorter construction period.
[0003] Existing waterproofing structures often use simple bolt connections to assemble the panels at the joints. Over time, gaps easily appear at these joints, allowing rainwater to seep into the roof structure and cause leaks. This affects the building's usability and increases future maintenance costs. Therefore, we propose a modular waterproofing structure for roof design. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a modular waterproof roof structure for building design, which solves the technical problem of poor sealing performance of existing modular waterproof roof structures, which leads to easy rainwater seepage into the roof. It achieves the goal of adding a sealing structure at the joints of the panels, thereby improving the sealing performance of the entire device and effectively preventing rainwater leakage.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Example 1
[0028] Existing prefabricated roof waterproofing structures suffer from poor sealing performance, leading to easy rainwater seepage. This embodiment provides a prefabricated roof waterproofing structure design. Please refer to [reference needed]. Figure 1 - Figure 5 This design incorporates a sealing structure at the joints of the panels, thereby enhancing the overall sealing performance and effectively preventing rainwater leakage. The building's modular waterproof roof structure includes a top plate 2 movably mounted on top of the panel 1. The panel 1 is fixed to the top plate 2 with bolts, allowing for assembly of the panel 1 and top plate 2 and facilitating their transport. The side of the panel 1 is equipped with a rainwater collection mechanism 3, and the top plate 2 has a sealing and reinforcement mechanism 4 that seals the joints where the two top plates 2 are pressed together. The collection mechanism 3 not only collects and utilizes rainwater but also filters impurities from it, improving recycling efficiency. The sealing and reinforcement mechanism 4 seals the joints of the panels, enhancing waterproofing and improving the overall structural strength of the panel assembly.
[0029] Existing waterproof structures often use simple bolts to connect panels. Over time, due to various factors, these bolts loosen at the joints, causing gaps between the panels. Rainwater seeps into the roof structure through these gaps, leading to leaks. This not only interferes with the building's normal use but also increases subsequent maintenance costs. To address these issues, a sealing and reinforcement mechanism 4 includes multiple sets of connecting bolts 41 connected above two sets of top plates 2. Two sets of fixing blocks 42 are installed at the top of the top plates 2. Connecting rods 43 are rotatably installed inside the fixing blocks 42. A sealing strip 44, adapted to the top of the top plate 2, is installed at the other end of the connecting rod 43. The sealing strip 44 is embedded in the circular grooves at the top of the two sets of top plates 2, thereby improving the installation stability of the sealing strip 44. Reinforcing components to stabilize the splicing plate 1 and the top plate 2 are provided on the inner side of the splicing plate 1. The two sets of top plates 2 are assembled together by connecting bolts 41. After the initial assembly is completed, the sealing strip 44 is embedded into the round groove at the top of the top plate 2 by rotating the connecting rod 43, thereby sealing the joint and improving the waterproof effect.
[0030] Existing waterproof structural panels are mostly connected using bolts or clips. However, simple connections cannot effectively reinforce the panels, making it difficult for them to form a stable whole under external forces, thus reducing the reliability and durability of the waterproof structure. To address these issues, a reinforcement component is proposed. This component includes two sets of fixing columns 4011 installed on the inner side of the splicing plate 1. The two sets of fixing columns 4011 are fixed together by fixing bolts, thereby improving the overall assembly stability of the device. A top block 4012 is installed at the top of the fixing column 4011. A reinforcing rod 4013, which is connected to the inner side of the top plate 2, is rotatably installed inside the top block 4012. The reinforcing rod 4013, the fixing column 4011, and the top plate 2 form a triangular structure, thereby reinforcing the top plate 2 and the splicing plate 1 and improving the stability of the installation. During the installation of splicing panel 1 and top panel 2, two sets of fixing columns 4011 are connected by fixing bolts, and the reinforcing rod 4013 is rotated so that its top end abuts against the inner side of top panel 2. The top end of the reinforcing rod 4013 is then fixed to the inner side of top panel 2 with fixing bolts, thereby improving the stability of waterproofing.
[0031] Example 2
[0032] Based on Example 1, such as Figure 1 - Figure 5 As shown, the existing prefabricated waterproof roof structure has poor sealing performance, which makes the roof prone to rainwater infiltration. However, the existing roof structure has almost no dedicated collection structure, and only the water is simply diverted to the ground through the eaves. There is a lack of effective collection and storage planning for rainwater, which makes it impossible to achieve efficient utilization of rainwater resources. Therefore, this device is also equipped with a structure for collecting rainwater.
[0033] Currently, most existing roof structures are not equipped with dedicated rainwater harvesting systems. Rainwater is simply channeled through simple eaves and eventually discharged directly to the ground. This method lacks a systematic plan for the effective collection and proper storage of rainwater, resulting in the inability to fully and efficiently utilize rainwater resources. In order to solve the above problems... The collection mechanism 3 includes two sets of guide frames 31 installed at the top of the top plate 2. The bottom of the inner side of the guide frame 31 is distributed at an angle, so that rainwater can be concentrated and flow to the outlet of the guide frame 31, improving the rainwater collection effect. A diversion plate 32 is installed on the side of the splicing plate 1, and a collection box 33 connected to the diversion plate 32 is installed on the side of the splicing plate 1. A liquid collection pipe 34 is connected to the bottom of the collection box 33. Two sets of support rails 35 are fixedly installed inside the collection box 33. A filter plate 36 is slidably connected on the support rails 35. The filter plate 36 is distributed directly below the connection between the collection box 33 and the diversion plate 32, which can filter the collected rainwater, prevent debris from being collected simultaneously with the rainwater, and improve the utilization effect of rainwater. Through the guiding effect of the guide frame 31, rainwater on the top plate 2 can be diverted into the inside of the guide plate 32, and then flow into the collection box 33. During the rainwater collection process, the filter plate 36 can filter the impurities in the rainwater, improving the rainwater recycling efficiency. The filter plate 36 adopts a pull-out installation, which makes it easy to replace.
