Description

Technical Field

[0001] This utility model belongs to the field of building drainage technology, and in particular relates to an expansion joint for building drainage eaves gutters. Background Technology

[0002] In building roof drainage systems, eaves gutter expansion joints are important structures used to cope with drainage structure deformation and prevent cracking. Due to factors such as temperature changes, foundation settlement, and thermal expansion and contraction of materials, buildings will experience slight displacement. Expansion joints can prevent the gutter from cracking due to stress concentration and ensure normal drainage function.

[0003] Because the expansion joint is filled with a padding material to prevent dust and impurities from falling in, the dust and impurities accumulate over a long period of time and are difficult to collect and remove, thus increasing the difficulty of cleaning. To address this, we propose an expansion joint for building drainage eaves gutters that filters dust and impurities, thus solving the shortcomings of existing technologies. Utility Model Content

[0004] The purpose of this utility model is to provide an expansion joint for building drainage eaves gutters, which filters dust and impurities in the gaps, thereby facilitating centralized treatment and solving the aforementioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A building drainage eaves gutter expansion joint includes an expansion joint opened at the bottom of the inner cavity of the eaves gutter. One side of the eaves gutter is located at the top of one side of the wall and is integrally cast. A reinforcing rib is pre-embedded and cast at the bottom of the inner cavity of the expansion joint. An expansion plate is welded to the top of the reinforcing rib. A filling pad is embedded in the inner surface of the expansion plate. A filter screen is detachably connected to the top of the expansion plate. Concrete is poured into the inner cavity of the expansion joint. A waterproof coating is applied to the concrete and the top of the expansion plate.

[0006] Preferably, the inner cavity of the telescopic plate is provided with an embedding groove, and the filling pad is filled in the embedding groove.

[0007] Preferably, the concrete fills the interior of the reinforcing bars, and the top end face of the concrete is flush with the bottom of the eaves gutter cavity.

[0008] Preferably, the filter screen is a filter screen structure, the filter screen is inclined, and the filter screen is fixedly connected to the top end face of the telescopic plate by mounting screws.

[0009] Preferably, the gap between the filter screen and the telescopic plate is filled with a filler strip, and the top end face of the filler strip is flush with the top end face of the concrete.

[0010] Preferably, the filter screen protrudes from the top end face of the concrete by a distance of 0.5 cm to 1 cm.

[0011] The beneficial effects of this utility model are: 1. This utility model uses reinforcing ribs pre-embedded in the inner cavity of the expansion joint, and an expansion plate welded to the outer surface of the reinforcing ribs to support the expansion plate. Then, sealing tape is used to bond the expansion plate to the top, and concrete is poured into the inner surface of the expansion joint to limit and fix the expansion plate. A filling pad is filled into the inner surface of the expansion plate to filter dust and impurities. At the same time, a filter screen is installed on the top of the expansion plate to facilitate the centralized cleaning of impurities and dust. 2. This utility model provides a filling pad that is easily installed and removed from the embedding groove. 3. This utility model uses a filter screen with an inclined design to filter dust and impurities. The inclined design also helps the dust and impurities to slide off, and the flowing water helps the impurities to move away. 4. This utility model prevents dust accumulation in the gap between the filter screen and the telescopic plate by filling the gap with a filler strip, thereby reducing dust accumulation.

[0014] In the following description, embodiments of the building drainage eaves gutter expansion joint of this utility model will be described with reference to the accompanying drawings. Example 1

[0015] Figure 1-4This invention illustrates an embodiment of an expansion joint for a building drainage eaves gutter, comprising an expansion joint 3 formed at the bottom of the inner cavity of the eaves gutter 2. One side of the eaves gutter 2 is located at the top of one side of the wall 1 and is integrally cast. A reinforcing rib 4 is pre-embedded at the bottom of the inner cavity of the expansion joint 3, and an expansion plate 5 is welded to the top of the reinforcing rib 4. A filling pad 6 is embedded in the inner surface of the expansion plate 5, and an embedding groove is provided in the inner cavity of the expansion plate 5. The filling pad 6 is filled in the embedding groove, which allows for easy installation and removal of the filling pad 6. A filter screen 7 is detachably connected to the top of the expansion plate 5. The filter screen 7 protrudes from the top end face of the concrete 9 by 0.5 cm to 1 cm. The filter screen 7 is a filter structure with an inclined design and is fixedly connected to the top end face of the expansion plate 5 by mounting screws. The filter screen 7 is a filter structure with an inclined design to filter dust and impurities. The inclined design also helps dust and impurities slide off, facilitating their flow in running water. The inner cavity of the expansion joint 3 is filled with concrete 9. The concrete 9 and the top of the expansion plate 5 are coated with a waterproof coating 8. Reinforcing ribs 4 are pre-embedded in the inner cavity of the expansion joint 3, and the expansion plate 5 is welded to the outer surface of the reinforcing ribs 4, thus supporting the expansion plate 5. Sealing tape is then used to adhere the top of the expansion plate 5, thereby pouring concrete 9 onto the inner surface of the expansion joint 3 to limit and fix the expansion plate 5. A filling pad 6 is filled into the inner surface of the expansion plate 5 to filter dust and impurities. The filter screen 7, installed on top of the expansion plate 5, facilitates the centralized cleaning of impurities and dust through filtration. Example 2

[0016] Figure 1-4 This invention illustrates an embodiment of an expansion joint for a building drainage eaves gutter, comprising an expansion joint 3 formed at the bottom of the inner cavity of the eaves gutter 2. One side of the eaves gutter 2 is located at the top of one side of the wall 1 and is integrally cast. A reinforcing rib 4 is pre-embedded and cast at the bottom of the inner cavity of the expansion joint 3. An expansion plate 5 is welded to the top of the reinforcing rib 4. A filling pad 6 is embedded and filled on the inner surface of the expansion plate 5. A filter screen 7 is detachably connected to the top of the expansion plate 5. A filling strip 10 is filled in the gap between the filter screen 7 and the expansion plate 5. The top end face of the filling strip 10 is flush with the top end face of the concrete 9. By filling the gap between the filter screen 7 and the expansion plate 5 with the filling strip 10, dust accumulation in the gap between the filter screen 7 and the expansion plate 5 can be avoided, thereby reducing dust accumulation. The inner cavity of the expansion joint 3 is filled with concrete 9, which fills the interior of the reinforcing rib 4. The top end face of the concrete 9 is flush with the bottom of the inner cavity of the eaves gutter 2. A waterproof coating 8 is applied to the top of the concrete 9 and the expansion plate 5.

[0017] Working principle: In use, the reinforcing rib 4 is pre-embedded in the inner cavity of the expansion joint 3, and the expansion plate 5 is welded to the outer surface of the reinforcing rib 4 to support the expansion plate 5. Then, the top of the expansion plate 5 is bonded with sealing tape, and concrete 9 is poured on the inner surface of the expansion joint 3 to limit and fix the expansion plate 5. The filling pad 6 is filled on the inner surface of the expansion plate 5 to filter dust and impurities. At the same time, the filter screen 7 is installed on the top of the expansion plate 5, and the filter screen 7 facilitates the centralized cleaning of impurities and dust. The filter screen 7 is inclined to filter dust and impurities, and the inclined design also helps the dust and impurities to slide off. With the flow of water, it also helps the impurities to flow away.
