Technical Field

[0001] The utility model relates to the technical field of roof drainage, in particular to a roof drainage structure. Background Art

[0002] Roofing refers to the surface of the roof of a building. When designing and constructing the roof, a roof drainage system needs to be arranged to ensure that rainwater and other accumulated water can be drained away quickly to prevent water from damaging the structure and interior of the building.

[0003] The roof drainage system commonly used at present usually includes two parts: a through-floor pipe embedded in the floor slab and penetrating the floor slab, and a floor drain installed in the low-lying part of the roof to collect rainwater. The floor drain is connected to the through-floor pipe, so that rainwater and other accumulated water on the roof can be discharged through the through-floor pipe. However, in the actual construction, due to inaccurate height design of the through-floor pipe, there is a height difference between the top of the through-floor pipe and the final finished surface of the roof. In order to make the height of the drain outlet of the floor drain consistent with the pre-designed drain outlet elevation after installation, it is usually necessary to connect the pipe or cut a section of the through-floor pipe to meet the installation requirements of the floor drain.

DETAILED DESCRIPTION

[0026] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0027] like Figure 1 to Figure 5 As shown, a roof drainage structure 100 of an embodiment of the utility model comprises a pre-buried pipe 1 and a floor drain 2; the pre-buried pipe 1 is pre-buried in the floor slab, and its length is less than the thickness of the floor slab; the floor drain 2 comprises a drain portion 21 and a connecting portion 22; a plurality of drain ports 211 are provided on the peripheral side wall of the drain portion 21, a drain channel 212 is provided in the drain portion 21, each of the drain ports 211 is communicated with the drain channel 212, a connecting channel 221 is provided in the connecting portion 22, and the drain channel 212 is communicated with the connecting channel 221; an external thread 222 is provided on the peripheral side wall of the connecting portion 22, an internal thread 11 is provided on the inner wall of the pre-buried pipe 1, and the connecting portion 22 is threadedly connected to the pre-buried pipe 1;

[0028] The length of the connecting portion 22 is defined as L1, the length of the embedded pipe 1 is defined as L2, and 0.5*L2≤L1≤0.8*L2.

[0029] Based on the above technical solution, the roof drainage structure 100 includes a pre-buried pipe 1 and a floor drain 2, and the floor drain 2 includes a drainage portion 21 and a connecting portion 22. Through the threaded connection between the connecting portion 22 and the pre-buried pipe 1, the connecting portion 22 can adjust its relative height with the pre-buried pipe 1, so that the overall height of the roof drainage structure 100 is adjustable, thereby avoiding the need for the pre-buried pipe 1 to be cut or connected so that the height of the drainage port 211 of the floor drain 2 after construction and installation is consistent with the pre-designed drainage port elevation. The height of the drainage port 211 can be adjusted simply by adjusting the connecting portion 22. In addition, the lengths of the connected connecting portion 22 and the embedded pipe 1 are limited to avoid the length L1 of the connecting portion 22 being close to the length L2 of the embedded pipe, thereby avoiding interference between the connecting portion 22 and subsequent pipes when moving downward; and avoiding the length L1 of the connecting portion 22 being too short, resulting in the overall length of the connecting portion 22 after being connected to the embedded pipe 1 being insufficient to make the height of the drain port 211 consistent with the designed drain elevation; and when pouring the floor slab and constructing the roof waterproof layer, the floor drain 2 can be adjusted to block debris by using the side walls below the drain port 211 and the side walls of the connecting portion 22 to prevent construction materials, debris, etc. from entering the embedded pipe 1 and subsequent pipes from the drain port.

[0030] Preferably, if Figure 1 As shown, in this embodiment, the internal thread 11 is only provided at the middle and upper part of the inner wall of the embedded pipe 1 , and the lower part of the embedded pipe 1 is not provided with an internal thread, so that the subsequent pipeline can be inserted into the embedded pipe 1 and sleeved with the embedded pipe 1 .

[0031] Furthermore, if Figure 4 As shown, the bottom heights of the plurality of drain ports 211 are consistent, so as to facilitate positioning during production and processing and to facilitate stable drainage.

[0032] Furthermore, if Figure 5 As shown, a plurality of drain ports 211 are evenly spaced along the circumference of the drain portion 21, so that the floor drain 2 can collect rainwater from all directions to ensure drainage efficiency.

[0033] Furthermore, if Figure 2 As shown, when pouring concrete for the floor slab, if the concrete is not vibrated and compacted, the concrete cannot be tightly bonded inside, and leakage is likely to occur between the periphery of the embedded pipe 1 and the floor slab; a water stop strip 3 is sleeved on the periphery of the embedded pipe 1 to improve the stability of the connection between the embedded pipe 1 and the poured concrete, making the pre-embedded pipe 1 and the floor slab denser, thereby preventing rainwater from leaking downward from the gap between the periphery of the embedded pipe 1 and the floor slab.

[0034] Furthermore, if Figure 4As shown, the diameter of the drainage portion 21 gradually increases from top to bottom to improve drainage efficiency, and the diameter of its bottom end is equal to the diameter of the connecting portion 22, which facilitates the docking and positioning of the drainage portion 21 and the connecting portion 22 during processing and production.

[0035] Furthermore, if Figure 1 to Figure 3 As shown, the axial direction of the embedded pipe 1 is usually perpendicular to the floor slab, so that the drainage is smooth and the drainage efficiency is guaranteed, and the required length of the embedded pipe 1 is the shortest, which can reduce the construction cost; and in order to ensure that the embedded pipe 1 does not deviate during the construction process, it is necessary to fix the embedded pipe 1 to the formwork of the roof to be poured, therefore, a connecting structure 5 is provided on the outer peripheral ring of the bottom end of the embedded pipe 1, so as to facilitate the connection and fixation of the embedded pipe 1 to the formwork, so as to avoid shaking and deviation of the embedded pipe 1 during the pouring process.

[0036] Furthermore, if Figure 3 As shown, in order to facilitate the connection between the connecting structure 5 and the template, a plurality of connecting holes 51 are arranged at intervals on the connecting structure 5, and the connecting holes 51 penetrate the two side surfaces of the connecting structure 5 in the axial direction of the embedded pipe 1, so that fasteners can be used to pass through the connecting holes 51 to connect the connecting structure 5 and the template, thereby completing the connection between the embedded pipe 1 and the template.

[0037] Furthermore, when the embedded pipe 1 and the subsequent pipeline are connected, a sleeve method is usually used, that is, the subsequent pipeline is inserted into the embedded pipe 1, and the gap between the two is filled with waterproof materials and adhesives such as glue, but the sleeve joint is prone to leakage due to material aging and other reasons; in this embodiment, the lower inner wall of the embedded pipe 1 is provided with a waterproof ring 4, and the waterproof ring 4 is extended along the radial direction of the embedded pipe 1 toward the central axis of the embedded pipe 1, and a channel for rainwater to flow is formed in the middle, and the top surface of the waterproof ring 4 guides water to move to the channel instead of falling vertically to the sleeve joint position of the embedded pipe 1 and the subsequent pipeline, thereby avoiding rainwater erosion of glue and other materials at the sleeve joint position, and avoiding leakage at the sleeve joint of the embedded pipe 1 and the subsequent pipeline, thereby eliminating the leakage problem caused by aging of glue or insufficient glue at the sleeve joint position of the embedded pipe 1 and the subsequent pipeline. The common waterproof strip can form the annular waterproof ring 4 in this embodiment by docking at both ends.

[0038] The working process of the utility model is as follows: before pouring the floor slab, the connecting portion 22 of the floor drain 2 is connected to the embedded pipe 1, and the position of the floor drain 2 is adjusted so that the height of the drain port 211 is higher than the designed drain elevation, and the embedded pipe 1 is connected and fixed to the template of the floor slab to be poured through the connecting hole 51 of the connecting structure 5; then the floor slab is poured and the roof waterproofing layer and other roof construction are carried out. After the roof construction is completed, the floor drain 2 is rotated so that the height of the drain port 211 is consistent with the designed drain elevation, and rainwater and other accumulated water on the roof are collected at the floor drain 2, enter the floor drain 2 through the drain port 211, and pass through the drain channel 212, the drainage channel 221 and the embedded pipe 1 in turn, so as to be discharged to the subsequent rainwater pipe or other pipes, thereby completing the roof drainage.

[0039] In summary, the embodiment of the utility model provides a roof drainage structure 100, which includes a pre-buried pipe 1 and a floor drain 2. Through the threaded connection of the connecting part 22 in the pre-buried pipe 1 and the floor drain 2, the overall height of the roof drainage structure 100 can be adjusted, and then the pre-buried pipe 1 with a length less than the thickness of the floor slab can be used for pre-buried, avoiding the need to cut or connect the pre-buried pipe 1. Only by adjusting the height of the connecting part 22 relative to the pre-buried pipe 1, the height of the drain port 211 can be changed to make it consistent with the pre-designed drain port height; rainwater gathers at the floor drain 2, and the water is discharged through the drain port 211, the drain channel 212, the connecting channel 221 and the pre-buried pipe 1 in sequence, thereby realizing roof drainage.

[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
