The utility model discloses a flat roof deck drainage system belongs to the technical field who constructs drainage system, including many slopes type flat roof deck that catchments, catchment and all install the hydrocone type type water drainage tank that catchments on every base of slope position of type flat roof deck in many slopes, the hydrocone type is catchmented type water drainage tank and is included water catch bowl and rainbow suction hood, the tank bottom of water catch bowl is equipped with the delivery port that communicates with the roof drainage pipe, rainbow suction hood installs on the tank bottom of water catch bowl with opening state down, and rainbow suction hood covers the delivery port of water catch bowl, simultaneously, has seted up the inlet opening on rainbow suction hood's the wall body. The utility model relates to a flat roof deck drainage system, not only the drainage is quick, owing to cancelled eaves gutter, gutter, has effectively avoided flat roof deck's the various phenomenons of leaking, seep water moreover, has simplified roofing construction process simultaneously, has reduced roofing construction cost.
Description
Technical field
The utility model discloses a kind of flat roof deck drainage system, belongs to the technical field of architectural drainage system.
Background technology
The roof drainage of current flat roof deck, the method of general employing is that flat roof structure looks for slope, rainwater is pooled in eaves gutter, gutter along roof pitch, and the rainwater in eaves gutter, gutter is by overboard chieftain, and rain water on roof is entered surface drainage system with vertical rain pipe by roof drain.Because eaves gutter, gutter structure comparison are complicated, thin portion structure in work progress once due to constructor careless, will cause leak in a large number, seep water phenomenon, the leaking of eaves gutter, gutter, to seep water, the mistake water pipe that particularly gutter center is set a roof beam in place leaks, seeps water is the common fault being difficult in building construction overcome, and the maintenance items of headache the most in building construction guarantee is fulfiled by Ye Shi unit in charge of construction.
Utility model content
The purpose of this utility model is to provide a kind of flat roof deck drainage system, applies the flat roof deck of this drainage system, effectively can avoid variously leaking, seep water phenomenon, can simplify roofing construction operation simultaneously, reduce roofing construction cost.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of flat roof deck drainage system, is communicated with roof drainage pipe, comprises many slopes water collection type flat roof deck, bottom each slope of many slopes water collection type flat roof deck, position is all provided with hydrocone type water collection type rhone; Hydrocone type water collection type rhone comprises catch basin and syphon hood; The bottom land of catch basin is provided with the delivery port be communicated with roof drainage pipe; Syphon hood is arranged on the bottom land of catch basin with downward opening state, and the delivery port of catch basin covers by syphon hood, meanwhile, the wall body of syphon hood offers inlet opening.
As the further setting of such scheme, the notch edges of described catch basin, to turning up, forms a circle boss.
Described boss is horizontal ledge.
Described inlet opening is positioned on the position close to syphon hood opening.
A kind of flat roof deck drainage system of the utility model, eliminate eaves gutter, the gutter in conventional flat roof deck drainage system, roof slope making is arranged by roof drainage pipe and is carried out looking for slope, is catchmented in the roofing list slope of routine and change many slopes into and catchment, and adopt siphon principle in time rain water on roof to be got rid of (namely direct rain water on roof is pooled to hydrocone type water collection type rhone carry out draining).The main performance of a kind of flat roof deck of the utility model drainage system carries out draining when amount of precipitation is less in gravity drainage mode, siphonage will be formed once amount of precipitation larger (when rainwater face exceedes the syphon hood perforate in catch basin) rainwater, utilize siphonage, accelerate the flow velocity of water in roof drainage pipe, quick drain rain water on roof.
In a word, a kind of flat roof deck drainage system of the utility model, not only draining is quick, and owing to eliminating eaves gutter, gutter, effectively prevent flat roof deck variously to leak, seep water phenomenon, simplify roofing construction operation simultaneously, reduce roofing construction cost.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model (arrow in figure represents water (flow) direction);
Fig. 2 is that A-A in Fig. 1 is to structural representation;
Fig. 3 is the structural representation (arrow in figure represents water (flow) direction) that in the utility model, hydrocone type water collection type rhone matches with many slopes water collection type flat roof deck when installing.
Detailed description of the invention
Shown in composition graphs 1, Fig. 2, Fig. 3, a kind of flat roof deck drainage system of the utility model, is communicated with roof drainage pipe 3, comprises many slopes water collection type flat roof deck 1, bottom each slope of many slopes water collection type flat roof deck 1, position is all provided with hydrocone type water collection type rhone 2; Hydrocone type water collection type rhone 2 comprises catch basin 21 and syphon hood 22; The bottom land of catch basin 21 is provided with the delivery port 23 be communicated with roof drainage pipe 3; Syphon hood 22 is arranged on the bottom land of catch basin 21 with downward opening state, and the delivery port 23 of catch basin 21 covers by syphon hood 22, meanwhile, the wall body of syphon hood 22 offers inlet opening 24.
In the present embodiment, the notch edges of catch basin 21, to turning up, forms a circle boss 25.Boss 25 is preferably designed for horizontal ledge.Inlet opening 24 is positioned on the position close to syphon hood 22 opening.
In the utility model, many slopes water collection type flat roof deck 1 is looked for slope to arrange by roof drainage pipe 3 carrying out looking for slope, be directly pooled to by rain water on roof in the hydrocone type water collection type rhone 2 that is communicated with corresponding roof drainage pipe 3.In the present embodiment, the upper end of catch basin 21 is arranged in the roof construction layer 11 of many slopes water collection type flat roof deck 1, is equipped with roof waterproof layer 12 above roof construction layer 11.Do water-tight process between roof waterproof layer 12 and catch basin 21, the connection between roof drainage pipe 3 and the delivery port 23 of catch basin 21 adopts glue bonding.
In the present embodiment, the material of catch basin 21 is preferably pottery, man-made stone or stainless steel products, simplifies site operation, reduces site operation node, makes whole roof drainage system more smoothly without ponding, thus avoid further variously leaking, seep water phenomenon.Reduce cost, a drain gully is set for 18 meters of spacing (maximum roofing area is 200 square metres), native system catchments compared with water discharge method with existing gutter, construction costs can be reduced: one, cast-in-situ concrete gutter beam, 18.00*0.25*0.5=2.25, with 1500 yuan every cube calculating, cost is 3375 yuan; Gutter facade cement mortar is whitewashed, 18.00*0.50*2.00=18 ㎡, and with 45 yuan every square calculating, cost is 810 yuan; Gutter facade waterproof coiled material, 18.00*0.50*2.00=18 ㎡, with 75 yuan every square calculating, cost is 1350 yuan, need increase this device and be about 350 yuan, and that is every drain gully can save the construction costs of 5185 yuan.
Above-described embodiment only illustrates inventive concept of the present utility model for explaining, but not the restriction to the utility model rights protection, all changes utilizing this design the utility model to be carried out to unsubstantiality, all should fall into protection domain of the present utility model.
