[0036] See also Figures 1 to 5 The present invention provides an upper and lower double drainage device for an upright roof and a construction method, wherein the roof includes a roof panel 4 and a roof structure layer arranged on the roof panel 4, and the drainage device includes: a lower drainer 2 arranged in the roof panel 4, the lower drainer 2 is arranged to penetrate the roof panel 4, the drainage port of the lower drainer 2 is arranged on the top surface of the roof panel 4, a plurality of adjustment members 3 connected to the top of the lower drainer 2, the support height of the adjustment member 3 is adjustable, and an upper drainer 1 is partially inserted in the lower drainer 2, the upper drainer 1 is connected to the adjustment member 3, and the support height of the adjustment member 3 is adjusted so that the drainage port of the upper drainer 1 can be located on the top surface of the roof structure layer.

[0037] Preferably, the roof structure layer includes a concrete roof panel 4, a slope layer 5, an insulation layer 6, a leveling layer 7, a waterproof layer 8, an isolation layer 9, and a concrete protective layer 10 from top to bottom. The lower drainer 2 is placed in the roof panel 4, and the bottom of the lower drainer 2 passes through the bottom of the roof panel 4. The slope layer 5 is then used to guide the rainwater that has penetrated into the structural layer to the drain port of the lower drainer 2 for discharge. The upper drainer 1 is arranged below the concrete protective layer 10, and a slope is provided above the concrete protective layer 10 at the drain port. The slope is used to input external rainwater into the drain port for drainage.

[0038] Furthermore, by setting the upper drainer 1 parallel to the roof, rainwater on the roof can be quickly drained, and then the lower drainer 3 is flush with the edge of the waterproof layer 8 to drain the rainwater that has penetrated into the waterproof layer 8, thereby solving the problem that rainwater cannot be discharged in time, causing water to seep into the waterproof layer 8 and cause damage.

[0039] In a specific embodiment of the present invention, the lower drain 3 includes a second connecting plate and a jacket drain pipe installed at the bottom of the second connecting plate, and an opening is provided on the second connecting plate at a position corresponding to the pipe opening of the jacket drain pipe.

[0040] Furthermore, the second connecting plate is a steel plate disc with an inner diameter of 115 mm, an outer diameter of 170 mm, and a thickness of 10 mm.

[0041] Furthermore, by making the diameter of the outer drain pipe larger than that of the inner drain pipe, the inner drain pipe can enter the outer drain pipe after installation. When the inner drain pipe drains water, the water flow can be directly discharged from the outer drain pipe. The drainage position is covered with wire mesh to avoid blockage. The spacing between the drainage outlets is not less than 2 cm, and the upper end of the outer drain pipe extends out to the height of the floor.

[0042] In a specific embodiment of the present invention, the upper drainer 1 includes a first connecting plate and an inner drain pipe installed at the bottom of the first connecting plate, and an opening is provided on the first connecting plate at a position corresponding to the pipe opening of the inner drain pipe.

[0043] Preferably, an opening corresponding to the inner drain pipe is provided on the first connecting plate so that rainwater on the roof can flow into the inner drain pipe from the opening to avoid rainwater accumulation on the connecting plate. The first connecting plate 1 is a steel plate disc with an inner diameter of 75 mm, an outer diameter of 160 mm and a thickness of 10 mm.

[0044] Furthermore, the first connecting plate and the second connecting plate are made of steel plates, and a wire mesh is arranged between the two. The first connecting plate and the second connecting plate are wrapped with the wire mesh to effectively prevent concrete blocks and other foreign objects from entering between the first connecting plate and the second connecting plate to cause blockage, and 2 cm pebbles are arranged around the wire mesh for filtering to further prevent the outer wire mesh of the device from being blocked. The inner drainage pipe is a 75 mm diameter iron circular pipe, and the outer drainage pipe is a 100 mm diameter iron circular pipe. There is an offset part between the inner drainage pipe and the outer drainage pipe. The purpose of the offset part is to discharge hidden water between the floor structure layer and the protective layer to avoid serious quality problems caused by long-term water accumulation.

[0045] In a specific embodiment of the present invention, the inner drain pipe portion extends into the lower drain 2.

[0046] Furthermore, the inner drain pipe partially extends into the lower drain 2 so that rainwater will not flow out of the lower drain 2 when discharged from the inner drain pipe, thereby preventing rainwater from overflowing from the drain pipe.

[0047] Furthermore, a wire mesh is arranged between the lower drain 2 and the inner drain pipe, which is helpful to avoid blockage of the offset part. By rotating the positive and negative wire sleeves, the distance between the inner drain pipe and the outer drain pipe structure can be adjusted according to the thickness of the construction layer.

[0048] In a specific embodiment of the present invention, a drainage space for draining rainwater from the waterproof layer is provided between the inner drainage pipe and the outer drainage pipe.

[0049] Furthermore, the drainage space provided between the inner drainage pipe and the outer drainage pipe can be used to discharge rainwater that has penetrated the waterproof layer from the drainage space, thereby reducing the problem of water accumulation in the waterproof layer and achieving the effect of reducing the rapid aging of the waterproof layer.

[0050] In a specific embodiment of the present invention, the outer contours of the second connecting plate and the first connecting plate are circular.

[0051] In a specific embodiment of the present invention, the adjusting member 2 includes a first bolt column connected to the bottom of the first connecting plate, a second bolt column connected to the top of the second connecting plate, and a positive and negative thread sleeve threadedly connected to the first bolt column and the second bolt column.

[0052] Furthermore, there are multiple first bolt columns and second bolt columns and positive and negative thread sleeves, which can be arranged according to construction requirements.

[0053] In a specific embodiment of the present invention, the positive and negative thread sleeve drives the first bolt column and the second bolt column to move closer to or away from each other in the positive and negative thread sleeve through rotation, so that the upper drainer 1 can be adjusted to a height with the lower drainer 3 .

[0054] Furthermore, the height between the upper drainer 1 and the lower drainer 3 can be adjusted by rotating the forward and reverse wire sleeves, so that after the lower drainer 3 is fixed in the placement groove, the upper drainer 1 can be adjusted in height according to the position of the roof and be parallel to the roof.

[0055] In a specific embodiment of the present invention, the adjusting member 2 is vertically arranged between the upper drainer 1 and the lower drainer 3 .

[0056] A vertical double drainage device for a roof and a construction method thereof, comprising the following steps:

[0057] Step 1: When constructing the roof panel 4, bury the lower drain 2 in the roof panel 4, make the drain port on the top surface of the lower drain 2 flush with the top surface of the roof panel 4, and let the bottom of the lower drain 2 extend from the bottom of the roof panel 4;

[0058] Step 2: Install the upper drain 1 to the top of the lower drain 2 through the adjusting member 3, and adjust the supporting height of the adjusting member 3 according to the height of the roof structure layer to be constructed, so that the top surface of the upper drain 1 is flush with the top surface of the roof structure layer to be constructed;

[0059] Step 3: Wrap the isolation net on the outer side of the upper drain 1 and the adjusting member 3;

[0060] Step 4: construct the roof structure layer on the roof panel 4.

[0061] Furthermore, a rain grate is set on the top of the upper drain 1 to cover the drain outlet. The rain grate can block external debris to prevent debris from entering the drain outlet and causing blockage. An isolation net is wrapped around the outer side of the upper drain 1 and the adjusting member 3, and then pebbles of 2 cm in size are arranged around the isolation net for filtering to further prevent the probability of the outer isolation net of the device being blocked. The top of the upper drain pipe 1 is made flush with the edge of the groove on the roof through the adjusting member 3 to achieve timely discharge of rainwater on the roof. Then, an offset part is left between the upper drain pipe 1 and the lower drain pipe 2, and the hidden water between the protective layers is quickly discharged by using the offset part. The bottom of the lower drain pipe 2 is connected to the vertical drain pipe in the middle to achieve the effect of outputting the input rainwater downward, and then the roof panel concrete is poured on the roof.

[0062] The beneficial effects of the upright roof up-and-down double drainage device and construction method of the present invention are as follows:

[0063] 1. By welding the inner sleeve drainage pipe and the first bolt column to the bottom of the first connecting plate, the three are connected to obtain an upper drainage body for outputting rainwater on the floor slab, which can quickly drain the rainwater on the roof and prevent the rainwater on the roof from penetrating into the waterproof membrane and causing damage to the waterproof membrane, thereby preventing the penetrated rainwater from affecting normal living.

[0064] 2. By setting staggered spaces between the inner drainage pipe and the outer drainage pipe, the hidden rainwater between the floor structure layer and the protective layer can be discharged through the staggered spaces to avoid serious quality problems caused by long-term water accumulation.

[0065] 3. The upper and lower drainage devices can be adjusted to the construction height according to the roof design through the positive and negative thread sleeves. The structure is simple and easy to install.
