Description

Technical Field

[0001] This utility model relates to the field of roof eaves drainage technology, and more specifically, to a drainage device for building eaves. Background Technology

[0002] Roof eaves drainage systems are an important component of building drainage systems. They are usually installed at the edge of the roof to prevent rainwater from seeping into the building interior or eroding the building structure. They are crucial for protecting the building structure and indoor environment, and can effectively reduce the erosion of the building's appearance by rainwater, thus maintaining the building's aesthetic appeal.

[0003] Patent CN222862718U discloses a roof waterproofing device for building design. It uses equidistantly distributed support components to support a drainage component, which collects and guides rainwater from the eaves. A drainage channel collects the rainwater from the eaves and discharges it through a drainage pipe. A filter screen filters the rainwater entering the drainage channel. However, in this roof waterproofing device, the curved support strip only has a fixed structure on one side. The weight of the water it supports can cause deformation of the curved support strip, potentially damaging the drainage device and preventing effective drainage of the roof eaves. Summary of the Invention

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a drainage device for building eaves.

[0005] A drainage device for building eaves includes a drainage channel and a drainage pipe communicating with and located below the drainage channel; it also includes an upper and lower retaining groove connected to the eaves body and arranged vertically, and a support for supporting the drainage channel;

[0006] One side of the support is engaged with the upper slot, and the other side of the support is engaged with the lower slot through a limiting structure.

[0007] Furthermore, the upper slot is connected to the outer wall of the eaves body; the lower slot is connected to the outer wall of the side wall below the eaves body; the upper slot and the lower slot are located on the same vertical plane.

[0008] Furthermore, the upper and lower slot components have the same structure;

[0009] The upper slot includes a slot body and connecting plates fixed to its left and right sides. The slot body has a T-shaped groove with an opening at the top and an opening on the right side. The connecting plates have connecting holes and are fixed to the outer wall of the eaves body with expansion bolts.

[0010] Furthermore, the support includes a U-shaped support plate, one end of which is flush with the lower slot and fixedly connected to a connecting horizontal plate. The end of the connecting horizontal plate is used to engage with the lower slot. The end of the connecting horizontal plate is T-shaped and is adapted to the T-slot of the lower slot.

[0011] The other end of the U-shaped support plate is flush with the upper slot and is fitted with the limiting structure; the limiting structure includes an integrally arranged T-shaped end, a limiting plate, and a sleeve; the T-shaped end is T-shaped and is used to snap onto the upper slot; the other end of the limiting structure is a hollow sleeve, which is bolted to the top of the U-shaped support plate.

[0012] Furthermore, the U-shaped support plate has a first through hole, and correspondingly, the sleeve of the limiting structure has a second through hole.

[0013] Furthermore, a filter screen is provided inside the flow channel to filter the rainwater flowing into the flow channel; at least one flow pipe is connected to the bottom end of the flow channel.

[0014] Furthermore, a first limiting groove is provided on the side wall of the flow guide channel, and the limiting plate of the limiting structure is engaged in the first limiting groove to limit the flow guide channel.

[0015] Furthermore, an auxiliary plate is also provided above the flow guide groove. The auxiliary plate is located above the upper slot and is used to cover the upper slot.

[0016] Furthermore, the auxiliary plate is a bent plate, the top sidewall of the auxiliary plate is adjacent to the sidewall of the eaves body, and the bottom surface of the auxiliary plate is adjacent to the upper surface of the guide channel near the sidewall of the eaves body.

[0017] Furthermore, the auxiliary plate has a second limiting groove, the width of which is adapted to the limiting plate of the limiting structure; the second limiting groove and the first limiting groove are used together to engage the limiting plate of the limiting structure. That is, the limiting plate of the limiting structure simultaneously limits the flow channel and the auxiliary plate.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This drainage device, used for building eaves, uses a bracket to support the guide channel. One end of the bracket is connected to the lower slot via a connecting horizontal plate, and the other end is connected to the upper slot via a T-shaped end of a limiting structure, forming a double-sided fixing structure. This double-sided fixing method can effectively distribute the supported weight, avoid deformation and damage caused by single-sided fixing, and extend the service life of the drainage device.

[0020] Furthermore, an auxiliary plate is installed above the drainage channel. The auxiliary plate covers the upper card slot to prevent rainwater from directly washing over the upper card slot. At the same time, the auxiliary plate is connected to the eaves body and the drainage channel with structural adhesive, which enhances the drainage performance.

[0021] Furthermore, the guide channel is stably supported and limited by the support components and the limiting structure. The limiting plate of the limiting structure simultaneously engages with the first limiting groove of the guide channel and the second limiting groove of the auxiliary plate, ensuring the stable fixation of the guide channel. At the same time, the upper and lower locking components are fixed to the eaves body with expansion bolts, making installation simple and secure. Attached Figure Description

[0041] 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.

[0042] like Figures 1-5 As shown, this embodiment provides a drainage device for building eaves, including a guide channel 1 and a guide pipe 2 connected to and located below the guide channel 1; it also includes an upper retaining groove 4 and a lower retaining groove 5 connected to the eaves body 3 and arranged vertically, and a support member 6 for supporting the guide channel. One side of the support member 6 is engaged with the upper retaining groove 4, and the other side of the support member 6 is engaged with the lower retaining groove 5 through a limiting structure 7. The guide channel 1 is connected to both sides by the support member 6, which effectively prevents the problem of easy damage to the support strip structure that is fixed only on one side.

[0043] In this embodiment, as Figure 2 , Figure 6 and Figure 7 As shown, the upper slot 4 is connected to the outer wall of the eaves body 3; the lower slot 5 is connected to the outer wall of the side wall below the eaves body 3. The upper slot 4 and the lower slot 5 are located on the same vertical plane, that is, the upper slot 4 and the lower slot 5 are a certain distance apart in the horizontal direction and also a certain distance apart in the vertical direction.

[0044] Specifically, the upper locking slot 4 and the lower locking slot 5 have the same structure. The upper locking slot 4 includes a slot body 41 and connecting plates 42 fixed to its left and right sides. The slot body 41 has a T-shaped groove 411 with an opening at the top and an opening on the right side for easy locking. The connecting plates 42 have connecting holes 421 and are fixed to the outer wall of the eaves body 3 with expansion bolts.

[0045] In this embodiment, as Figure 2 , Figure 6 and Figure 8 As shown, the support member 6 includes a U-shaped support plate 61. One end of the U-shaped support plate 61 is flush with the lower retaining groove 5 and is fixedly connected to a connecting horizontal plate 62. The connecting horizontal plate 62 can be an I-beam. The end of the connecting horizontal plate 62 is T-shaped, adapted to the T-slot of the lower retaining groove 5, and the end of the connecting horizontal plate 62 is used to engage in the lower retaining groove 5. The other end of the U-shaped support plate 61 is flush with the upper retaining groove 4 and is fitted with a limiting structure 7. Wherein, as Figure 2 , Figure 6 , Figure 8 and Figure 9 As shown, the limiting structure 7 includes an integrally arranged T-shaped end 71, a limiting plate 72, and a sleeve 73. The T-shaped end 71 is T-shaped and is used to engage with the upper slot 4. The other end of the limiting structure is a hollow sleeve 73, which is bolted to the top of the U-shaped support plate 61. A first through hole 611 is provided in the U-shaped support plate 61, and correspondingly, a second through hole 731 is provided in the sleeve 73 of the limiting structure 7.

[0046] In this embodiment, as Figure 3 and Figure 4 As shown, a filter screen 8 is installed inside the flow channel 1 to filter rainwater flowing into the flow channel 1; at least one of the flow pipes 2 is connected to the bottom end of the flow channel 1. Specifically, a first limiting groove 11 is provided on the side wall of the flow channel 1, and the limiting plate 72 of the limiting structure 7 is engaged in the first limiting groove 11 to limit the flow channel 1.

[0047] To go further, such as Figures 3-5 As shown, an auxiliary plate 9 is also provided above the guide channel 1. The auxiliary plate 9 is located above the upper retaining slot 4 and is used to cover the upper retaining slot 4, effectively protecting it from rain. The auxiliary plate 9 is a bent plate. The top side wall of the auxiliary plate 9 is adjacent to the side wall of the eaves body 3, and the bottom end face of the auxiliary plate 9 is adjacent to the upper end face of the guide channel 1 near the eaves body 3. Furthermore, a second limiting groove 91 is provided on the auxiliary plate 9, the width of which is adapted to the limiting plate 72 of the limiting structure 7. The second limiting groove 91 and the first limiting groove 11 are used together to engage the limiting plate 72 of the limiting structure 7. That is, the limiting plate 72 of the limiting structure 7 simultaneously limits the guide channel 1 and the auxiliary plate 9.

[0048] When installing the support, first fix the upper slot 4 and the lower slot 5 to the outer wall of the eaves body 3 and the outer wall of the lower side wall of the eaves body 3 respectively according to the design position. Then, snap the T-shaped end of the connecting horizontal plate 62 of the support 6 into the T-shaped groove of the lower slot 5. Next, place the guide channel 1 into the U-shaped support plate 61 of the support 6. Then, put the sleeve 73 of the limiting structure 7 onto the part of the support 6 that is higher than the guide channel 1. At the same time, adjust the position of the guide channel 1 so that the first limiting groove 11 of the guide channel 1 corresponds to the position of the limiting plate 72 of the limiting structure 7. At this time, the T-shaped end 71 of the limiting structure 7 snaps into the T-shaped groove of the upper slot 4. Finally, the auxiliary plate 9 is placed over the upper slot 4 and the guide channel 1. The second limiting groove 91 of the auxiliary plate 9 corresponds to the position of the limiting plate 72 of the limiting structure 7. That is, the limiting plate 72 of the limiting structure 7 is located within the space formed by the first limiting groove 11 of the guide channel 1 and the second limiting groove 91 of the auxiliary plate 9. To ensure the stability of the auxiliary plate 9 installation and the rainproof effect on the upper slot 4, adhesive, such as structural adhesive, is applied to the top side wall and the bottom surface of the auxiliary plate 9. This ensures that the auxiliary plate 9 is adhered and that the connection does not leak.

[0049] The drainage device for building eaves provided in this embodiment consists of multiple sets of equally spaced supporting structures, including the upper retaining groove 4, lower retaining groove 5, and support member 6, along with the limiting structure 7, which together support the drainage channel 1. Rainwater flows down from the eaves and enters the drainage channel 1. After being filtered by the filter screen 8 inside the drainage channel, the rainwater is discharged from the drainage pipe 2 at the bottom of the drainage channel 1. The drainage channel 1 is supported by the support member 6. One end of the support member 6 is engaged in the T-slot of the lower retaining groove 5 via a connecting horizontal plate 62, and the other end is engaged in the T-slot of the upper retaining groove 4 via the T-shaped end 71 of the limiting structure 7. Simultaneously, the limiting plate 72 is engaged in the first limiting slot 11 and the second limiting slot 91 of the auxiliary plate 9 of the drainage channel 1, ensuring the stable fixation of the drainage channel 1. The auxiliary plate 9 covers the upper retaining groove 4 and the drainage channel 1, preventing rainwater from directly washing over the upper retaining groove 4, thus providing rain protection.

[0050] The drainage device for building eaves provided in this embodiment uses a support member 6 to support the guide channel 1. One end of the support member 6 is connected to the lower slot member 5 through a connecting horizontal plate 62, and the other end is connected to the upper slot member 4 through the T-shaped end 71 of the limiting structure 7, forming a double-sided fixing structure. This double-sided fixing method can effectively distribute the supported weight, avoid deformation and damage caused by single-sided fixing, and extend the service life of the drainage device.

[0051] The drainage device for building eaves provided in this embodiment has an auxiliary plate 9 above the guide channel 1. The auxiliary plate 9 covers the upper slot 4 to prevent rainwater from directly washing the upper slot 4. At the same time, the auxiliary plate 9 is connected to the eaves body 3 and the guide channel 1 by structural adhesive, which enhances the drainage performance.

[0052] The drainage device for building eaves provided in this embodiment achieves stable support and limitation for the guide channel 1 through the support member 6 and the limiting structure 7. The limiting plate 72 of the limiting structure 7 is simultaneously engaged in the first limiting groove 11 of the guide channel 1 and the second limiting groove 91 of the auxiliary plate 9, ensuring the stable fixation of the guide channel 1. At the same time, the upper locking member 4 and the lower locking member 5 are fixed to the eaves body 3 by expansion bolts, making the installation simple and firm.

[0053] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
