Through the tip of heat preservation 3 sets up end cap 5, can be right heat preservation 3 carries out banding and spacing, simultaneously end cap 5 still is used for fixing wash-out pipe 6, in order to guarantee the rivers of heat preservation 3 are unblocked, have solved heat preservation 3 long-term ponding causes that the heat preservation effect weakens and ponding inflation arouses protective layer fracture, uplift and causes the problem of destruction to waterproof layer 2. In addition, compare with traditional drainage structure, the escape canal that this embodiment provided is made and need not to occupy extra time limit for a project, construction convenience.
Specifically, in this embodiment, the main body portion includes a structural layer 1, a waterproof layer 2, and an insulating layer 3, which are sequentially disposed from bottom to top, and in addition, the main body portion may further include, but is not limited to, a slope layer and a leveling layer disposed between the structural layer 1 and the waterproof layer 2, and a protective layer disposed above the insulating layer 3, which is not limited in this application.
In this embodiment, the heat preservation layer 3 can adopt conventional heat preservation board, and the waterproof layer 2 is water proof coating or waterproofing membrane, and this application does not limit this.
In this embodiment, the drainage structure comprises a gutter 4, the gutter 4 is located outside the main body portion, and the gutter 4 is mainly used for collecting rainwater in an organized drainage mode of a roof or floor structure.
Preferably, a plurality of rainwater outlets 7 are further arranged in the gutter 4 and used for guiding rainwater in the gutter 4 to flow into a drainage pipe. In this embodiment, the position of the rain inlet 7 may correspond to the position of the drain pipe 6, so as to rapidly drain the rain water in the insulating layer 3.
Referring to fig. 1, the drainage structure further includes a plug 5, the plug 5 is disposed at an end of the insulating layer 3 and located on the waterproof layer 2, and the plug 5 is mainly used for preventing the insulating board from sliding down and sealing edges of the insulating board.
In this embodiment, the plug 5 is a concrete structure. In this embodiment, the construction of the inverted roof drainage structure follows the following flow: construction preparation → construction of a slope layer → construction of a leveling layer → construction of a waterproof layer 2 → construction of an insulating layer 3 → construction of a protective layer, wherein the construction of the plug 5 is positioned between the construction of the waterproof layer 2 and the construction of the insulating layer 3, and the concrete construction steps are as follows:
after the waterproof layer 2 is constructed, firstly cleaning a surface layer to be used as a base layer of the plug 5;
making a height control ash cake of the plug 5 according to the thickness of the insulating layer 3 and the lowest requirement of slope finding in the design requirement;
then pulling through the wire, hanging a template, and determining the position and the style of the plug 5;
pre-burying construction of the water drain pipe 6 is carried out, and concrete is poured and pounded after the water drain pipe 6 is buried;
and finally, curing the poured and tamped concrete of the plug 5, and laying heat-insulating plates after the templates are disassembled.

In this embodiment, the drainage ditch structure further comprises a plurality of drain pipes 6, the drain pipes 6 stretch out the one end of the plug 5 is bent downwards, so that the rainwater of the heat preservation layer 3 is discharged to the gutter 4.
Further, the outlet pipes 6 are arranged at equal intervals along the extending direction of the plugs 5, so that rainwater in the heat preservation layer 3 flows to the eaves gutter 4 uniformly, and the intervals are attractive. Of course, the drain pipes 6 may also be disposed at unequal intervals or in a certain regular manner along the extending direction of the plugs 5, which is not limited in this application.
Furthermore, the distance between two adjacent water drain pipes 6 is between 1m and 1.5 m.
In this embodiment, the drain pipe 6 is a stainless steel pipe or a PVC pipe.
Compared with the conventional drainage structure, the drainage structure provided by the embodiment has the advantages that the sealing of the heat-insulating layer 3 is made especially for the requirement of the inverted roof on the drainage of the heat-insulating layer 3, the fine structures such as smooth drainage of the water outlet and the like are further improved, and the heat-insulating effect weakening caused by long-term water accumulation of the heat-insulating layer 3 and the damage to the waterproof layer 2 and the cracking and bulging of the protective layer caused by water accumulation expansion can be effectively prevented. Generally, the project is on the roofing because the seepage water that the heat preservation 3 ponding caused, and the later stage is repaired and is dealt with will be very troublesome, not only consumes manpower and time, and large-area repair can cause great economic loss moreover.
Taking the treatment cost of water seepage of one 1 square meter roof as an example:
and (3) roof repair labor cost: 300 yuan/day × 2 × 3 is 1800 yuan;
cost of roof repair materials: 1500 yuan/square meter multiplied by 1 is 1500 yuan;
other expenses for roof repair: 200 yuan
Total cost of repair: 1800+1500+200 ═ 3500 yuan
Then the repair of 1 square meter roofing infiltration will consume 2 workman, and 3 worker days of every person cost 3500 yuan, and the inversion formula roofing drainage structures that adopts this embodiment to provide then can avoid taking place the roofing seepage, greatly saves the repair cost in later stage.
Therefore, compare with domestic traditional inversion formula roofing drainage structures, the inversion formula roofing drainage structures that this embodiment provided can avoid doing the exhaust passage on the roofing and roofing blast pipe is set aside, makes the whole molding of roofing more pleasing to the eye stiff and graceful, also can prevent simultaneously that to store up the rainwater in heat preservation 3 and arouse that long-term ponding is not scattered, both reduces the seepage problem of roofing, also makes the heat preservation of design, waterproof material better exert respective effect. And the leakage problem of the roof is reduced, the service life of the building can be greatly prolonged, and the maintenance cost is reduced.
