Description

Technical Field

[0001] The utility model relates to the technical field of building roof drainage, in particular to an embedded drainage device for a concrete roof. Background Art

[0002] When the flat roof of an existing building leaks, water will accumulate inside, that is, below the waterproof layer and above the structural layer. This leaking water enters the room through cracks and holes in the structural layer, affecting normal life and causing disputes. More seriously, the concrete structural layer is carbonized faster under the long-term erosion of water, and the internal steel bars corrode and expand, thus shortening the overall life of the building and bringing structural safety hazards.

[0003] There are two current maintenance technical solutions: the first is to dig the upper waterproof layer and insulation layer to the concrete structure layer, drain and dry manually, and restore to the original state. This renovation method is destructive, and its cost is usually several times or even dozens of times higher than the original investment, consuming a lot of labor and material costs; the second is to drill holes from the lower room upwards to drain, and then plaster and restore to the original state after draining. This method is a great improvement over the first method, but the disadvantage is that it will cause the lower room to be dirty, and the room cannot be used normally during drainage, and there is no long-term mechanism. Due to the construction period, it cannot be completely drained and then plastered and blocked, and the full cycle performance and convenience are not considered. Utility Model Content

[0004] The purpose of the utility model is to overcome the defects of the prior art and provide a concrete roof embedded drainage device.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A building roof embedded drainage device is installed on a water-containing roof. The roof is provided with a drainage hole that penetrates the concrete from the concrete slab. The drainage device is installed at one end of the drainage hole close to the ground, and comprises: a threaded tube, a sealing member sleeved on the outer edge of the threaded tube, and a fixing member.

[0007] As a preferred technical solution, the fixing member is a nut column, which is sleeved on the outside of the threaded tube and fixed to the gap between the linkage seal, concrete and the drainage device by tightening.

[0008] As a preferred technical solution, a gasket is provided between the nut column and the sealing member.

[0009] As a preferred technical solution, an evaporation plate is arranged at one end of the toothed tube away from the wall.

[0010] As a preferred technical solution, a gap is left between the evaporation plate and the end of the intermediate tube away from the wall.

[0011] As a preferred technical solution, the evaporation plate is installed and fixed on one end of the intermediate tube through an evaporation plate fixing piece.

[0012] As a preferred technical solution, the evaporation plate fixing member is fixedly connected to the side of the intermediate tube.

[0013] As a preferred technical solution, the evaporation plate fixing member is symmetrically arranged with respect to the intermediate tube.

[0014] As a preferred technical solution, one end of the toothed tube away from the wall is connected to a drain pipe.

[0015] As a preferred technical solution, the end of the drainage pipe away from the toothed tube is connected to a vacuum negative pressure water absorption device.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] The utility model uses embedded organized water diversion, which is placed inside the concrete to discharge the accumulated water that enters the waterproof layer in an organized and controllable manner, and is left inside the concrete for a long time after drainage. It effectively eliminates the problems of the prior art in terms of destructive renovation of the roof, incomplete and uncontrollable drainage, and lack of convenience for the full-cycle use of the building.

[0025] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and a specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0026] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0027] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0028] Example 1

[0029] The embedded drainage device for concrete roof comprises a threaded pipe 1, a sealing member 2, a gasket 3, a nut column 4, an evaporation plate 5 and an evaporation plate fixing member 6.

[0030] For the roof with water on the upper part, drill a hole upward from the lower part of the concrete slab. After drilling through the concrete, embed the toothed tube 1, seal 2, and gasket 3. Tighten the nut column 4 to link the seal 2 to seal the gap between the concrete 7 and the drainage device. Water can only flow from the toothed tube 1.

[0031] like Figure 5 As shown, the water on the roof can be quickly drained by connecting the intermediary pipe 1 and the drainage pipe 8 connected to the intermediary pipe 1 to the vacuum negative pressure water suction equipment.

[0032] Example 2

[0033] For roofs with water on the upper part, drill holes upward from the lower part of the concrete slab, and after drilling through the concrete, insert the toothed tube 1, seal 2, and gasket 3. Tighten the nut column 4 to link the seal 2 to seal the gap between the concrete 7 and the drainage device. Water can only flow through the toothed tube 1. In this state, the evaporation plate 5 and the evaporation plate fixing 6 are not installed.

[0034] like Figure 5 As shown, the water stored in the upper part is discharged in an organized manner through the intermediary pipe 1 and the drainage pipe 8 connected to the intermediary pipe under the action of gravity, and the drainage process does not affect the normal use of the lower room.

[0035] Example 3

[0036] After the above-mentioned scenario of Embodiment 1 or Embodiment 2, when the water inside the concrete roof is drained and only sporadic dripping occurs, the device is not dismantled as a whole, but only the temporary drainage pipe 8 is removed, and the evaporation plate 5 is installed through the evaporation plate fixing member 6. The device enters the long-term working mode.

[0037] like Figure 6As shown, in the long-term working mode, sporadic dripping water evaporates naturally on the evaporation plate 5. Under the connection of this device, the internal and external pressures of the roof are balanced, eliminating the bulging and cracking problem of the roof waterproof layer caused by the difference in internal and external pressures, thereby extending the working life of the roof waterproof layer.

[0038] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
