Description

Three rows of buckets

Technical Field

The invention relates to a novel roof drain device, namely a three-row bucket, wherein the three-row bucket can quickly collect and discharge the accumulated water on the roof on the premise of fully filtering sundries in the water in the roof area.

Background

The existing roof engineering technical specification and roof construction acceptance specification do not make hard regulation on the water falling hopper, and the reference standard which can be checked at present is GB50345-2012 roof engineering technical specification, and the specification has the following relevant regulations:

4.2.2 roof drainage modes can be divided into organized drainage and unorganized drainage. When organized drainage is carried out, a rainwater collection system is preferably adopted;

4.2.6 when gravity drainage is adopted, the number of vertical rainwater drainage pipes in each catchment area of the roof is not less than 2; the positions of the water falling port and the water falling pipe are determined according to the modeling requirements of the building, the roof catchment condition and other factors.

In fact, there are many roof-mounted falling hoppers, and by taking the falling hopper in an internal drainage mode as an example, a plastic pipe or an iron pipe is basically threaded onto the roof from the indoor, the upper opening is as high as the leveling layer, the coiled material is rolled into the pipe opening, and various water-avoiding devices (such as a water grate) are arranged on the pipe opening. However, such a downpipe has the following disadvantages:

(1) the diameter of the water falling port is the same as that of the drain pipe, and after the waterproof coiled material is rolled into the water falling port, the water inlet is much smaller than the inner diameter of the drain pipe, so that the roof drainage is not facilitated;

(2) the width of the coiled material in the water falling port is limited, and the coiled material is easy to open and warp edges so as to cause leakage;

(3) the maintenance is difficult after leakage, the waterproof maintenance of the coiled material is continuously carried out at the water falling port, the water falling port is smaller, the drainage is not smooth, and water is easy to accumulate on the roof;

(4) the water grate is easy to fall off and lose, so that a water falling port is blocked, and a large area of water is accumulated on a roof;

(5) can only collect roof rainwater and can not solve the problem of water vapor discharge in the heat-insulating layer.

The invention relates to a novel water falling hopper device, namely a three-row hopper, which consists of a base, a main row, a high partition cap or a low partition cap, wherein the base is arranged in a roof structure, the main row is arranged on the base, a water and steam discharging channel is reserved between the main row and the base and can discharge partial accumulated water and moisture in a heat insulation layer, the high partition cap or the low partition cap is arranged on the main row, and the high partition cap or the low partition cap is provided with a water grate, so that roof rainwater can be quickly collected and discharged under the condition of filtering sundries in rainwater.

Disclosure of Invention

The invention mainly aims to solve the problems of leakage of a drain port caused by infirm bonding of coiled materials of the drain port, water storage and the like, and simultaneously assists a double-drain bucket to solve a series of problems that water and moisture in a roof insulation layer cannot be discharged in time and the like. The technical scheme for solving the problems is to develop a novel water falling hopper, namely a three-row hopper, and the structural principle is as follows:

(1) the three rows of hoppers are thick at the top and thin at the bottom, so that roof rainwater can be quickly collected and discharged;

(2) the three-row bucket is provided with a main row and a base double-layer drainage device, the upper layer collects and discharges rainwater, and the lower layer collects and discharges water accumulated in the heat preservation layer;

(3) the separation caps (high separation caps and low separation caps) and the main row are screwed through screw ports to clamp the waterproof coiled material, so that the edge of an opening of the coiled material is prevented from being warped to cause leakage of a water falling port;

(4) the partition caps (high partition caps and low partition caps) are provided with water grates to prevent the water outlet from being blocked;

(5) after the roof is provided with the three rows of hoppers and the two rows of hoppers, the roof steam exhaust holes and the steam exhaust pipes can be omitted, and the roof leakage nodes are reduced.

It should be noted that the double-row bucket is another drainage and steam exhaust device developed based on the same concept as the invention, and is mainly used for draining accumulated water and moisture in the heat insulation layer, but cannot drain roof rainwater, so the best effect can be achieved only by using the double-row bucket and the three-row bucket together.

In the case of the use of three rows of hoppers in combination with other installations, the function of ventilating the roofing insulation is also provided, which is omitted here for brevity since this installation is not in the scope of this application and the installation plan is not yet published.

The three-row bucket base is provided with a reducing pipe which is conveniently connected with a water drop pipe, the upper opening is large, and enough space is provided for quickly collecting and discharging roof rainwater and accumulated water in the heat preservation layer. The base panel below has the base steady strip, and the firm strip is inlayed in structure screed-coat or looking for the slope layer, plays the unable adjustment base effect, and the plane regular slot on the base panel makes things convenient for bonding vapour barrier or inversion waterproof layer. A plurality of partition plates are arranged on the outer wall of the main row, and a drainage groove is formed by two adjacent partition plates and the outer wall of the main row. The main row is arranged in the base, and a drainage and steam exhaust channel is formed between the drainage groove and the base and is used for discharging accumulated water and moisture in the heat preservation layer. The main row panel is provided with a main row stabilizing strip below, the main row stabilizing strip is embedded in the heat-preservation slope finding layer to play a role in fixing the main row, and the regular grooves are formed in the upper portion of the main row panel to facilitate and firmly bonding the roof waterproof layer. The main drainage outfall is provided with internal threads, which is convenient for connecting with the separating caps (high separating cap and low separating cap). The outer opening thread is arranged below the partition cap panel and connected with the screw port of the main row, so that the main row and the partition cap can be connected stably after being screwed, the waterproof coiled material can be clamped, the coiled material at the water falling opening is prevented from being opened and raised, and leakage is prevented. The high-low separating caps are provided with the water grates, and the risk that the water grates of the conventional water falling hopper are easy to fall off and lose is avoided. The three rows of hoppers on the low partition caps are provided with horizontal water grates, and after the three rows of hoppers on the low partition caps are installed, the water grates are as high as the roof waterproof protective layer, so that people can move on the roof conveniently. Three rows of buckets of the high partition cap are provided with three-dimensional water grates, the risk coefficient of blockage by sundries is low, and the three-row bucket is suitable for being installed and used on roofs which are not accessible for a long time.

All parts of the three rows of hoppers are made of ABS plastic processing products, threads are never rusted, the separating caps are damaged, for example, the separating caps can be independently replaced after the water grate is damaged, and the three rows of hoppers are very convenient.

The water leakage of the water falling port is a major cause of roof leakage, and three rows of hoppers are arranged to solve the water leakage of the water falling port and reduce the waterproof maintenance frequency of the roof. Accumulated water in the heat-insulating layer of the roof is drained in time, so that the phenomenon that the building leaks three days in a house one day under rain can be avoided.

In summary, compared with the traditional downpipe, the three-row hopper has the following advantages:

(1) the base has a reducing part, the thin part has the same diameter with the water drop pipe, and the base is conveniently connected with the water drop pipe. The rainwater collecting port is larger than the caliber of the water drop pipe, so that rainwater is collected and discharged;

(2) after the separation caps are screwed and connected with the internal threads of the main row through the external threads, the panel of the separation caps and the panel of the main row clamp the waterproof coiled material, so that the closed end of the coiled material is not easy to open and warp, and the hidden danger of leakage of a water falling port is reduced;

(3) the water grate on the high-separation cap or the low-separation cap is not easy to fall off, and particularly the three-dimensional water grate is arranged around the high-separation cap and is not easy to block, so that accumulated water is not reserved at the roof drain hopper;

(4) the three-row bucket is provided with a main row and base double-layer drainage system, so that roof rainwater can be quickly collected and drained, accumulated water and moisture in the heat-insulating layer can be timely drained by the aid of the two-row bucket, heat-insulating efficiency of the heat-insulating layer can be improved, and service life of the heat-insulating layer can be prolonged;

(5) under the environment of dry air in sunny days, the three rows of hoppers can be combined with other facilities to ventilate the roof heat-insulating layer, and the waterproof and heat-insulating effects of the roof are further improved.
