Specific embodiment

To solve the problems, such as that Shimizu concrete building construction needs secretly to bury rain pipe, the utility model design one kind can connect it is more The roof drain of a charge for remittance gutter, and according to the structure of column and girder, design a kind of construction drainage knot for being embedded in building interior Structure.

Below in conjunction with the drawings and specific embodiments to the utility model proposes roof drain be described in further detail.According to The advantages of explanation and claims below, the utility model and feature will become apparent from.It should be noted that attached drawing is using very Simplified form and using non-accurate ratio, only to mesh that is convenient, lucidly aiding in illustrating the utility model embodiment 's.

Embodiment one

Refering to Fig. 1~Fig. 4, it illustrates the structure of roof drain in the present embodiment 10, Fig. 5, which gives, removes rain after double-edged fine-toothed comb 3 The perspective view of bucket.Roof drain 10 includes：Cavity 1 and the tail pipe 4 connected with cavity 1, cavity 1 have at least two to be interconnected Water inlet, rainwater flows into cavity 1 from each water inlet, and falls into tail pipe 4.Specifically, cavity 1 can be a rectangle stainless steel Pipe, and have there are two water inlet, tail pipe 4 connects at the middle part of rectangle stainless steel tube with rectangle stainless steel tube.Certainly, cavity 1 is gone back Three, four can be designed according to demand, even more water inlets；Such as：When needing to design four water inlets, cavity 1 can For cross tubing string cavity, wherein tail pipe 4 is connected at right-angled intersection.The mode that casting can be used in cavity 1 is molded, also optional With existing tubulose steel.

Further, in order to avoid the blocking of rainwater pipeline, the comb for stopping sundries is both provided in each water inlet Son 3, each double-edged fine-toothed comb 3 can be connect by bolt 5 with cavity 1；Also can be hinged by linkage and cavity 1, double-edged fine-toothed comb 3 Hinged mode can be convenient for raising double-edged fine-toothed comb with cavity 1.

Specifically, having several holes on double-edged fine-toothed comb 3, for the circulation of rainwater, this some holes can be bar shaped as shown in Figure 6 Hole 31 or circular hole.There are two mounting hole 32 on double-edged fine-toothed comb 3, for installation bolt or linkage.

For the ease of the circulation of rainwater, gap, the width in general gap are reserved between the lower end of double-edged fine-toothed comb 3 and cavity 1 Degree, if gap is excessive, may cause sundries to flow into equal to the width of bar hole 31.

For the ease of the installation of double-edged fine-toothed comb 3 and the installation of roof drain itself, each water inlet is both provided with connecting plate 2, even Fishplate bar 2 is welded on cavity 1, and is connect with double-edged fine-toothed comb 3, that is to say, that connecting plate 2 is equipped with threaded hole, and bolt 5 passes through mounting hole 32 screw in the threaded hole on connecting plate 2.If the two is hinge connection, threaded hole and mounting hole 32 are used to fixed hinge Mechanism.

Embodiment two

The present embodiment provides a kind of construction drainage structure, and the roof drain 10 being combined in embodiment.Refering to Fig. 6~ Fig. 7, which respectively show the sectional views and vertical view of construction drainage structure in the present embodiment.The construction drainage structure, including：It is vertical Column 60, girder 80, rain pipe 70 and at least one roof drain 10 as described in embodiment one, girder 80 are connected to column 60 Upper (column 60 is used to support girder 80), the both sides of girder 80 are respectively provided with gutter 90, and rain pipe 70 is embedded in column 60, rainwater Bucket 10 is embedded in girder 80, and connect the gutter of 80 both sides of girder, and the tail pipe 4 is connected with the rain pipe 70.In Fig. 7 Big arrow represents rainwater flow direction, and rainwater catchment flows into roof drain 10 in each gutter, and by water inlet, and rainwater is into one Step is embedded in by tail pipe 4, inflow in the rain pipe 70 in column 60, and rainwater flows to outdoor from rain pipe 70.

Specifically, the rain pipe of stainless steel can be selected in rain pipe 70.

Preferably, girder 80 generally comprises transverse beam and the longitudinal beam intersected with the transverse beam, transverse beam is perpendicular to vertical The crosspoint of Xiang Liang, transverse beam and longitudinal beam is connected on column 60；Construction drainage structure uses two roof drains 10, and buries It is located in transverse beam or longitudinal beam, illustrated in fig. 8 is that two roof drains 10 are embedded in transverse beam, when two roof drains 10 It is embedded in equally applicable in longitudinal beam, since transverse beam here is narrower than longitudinal beam, it is advantageous to be embedded in transverse beam；Into one Step, rain pipe 70 is in Y shapes, and is had there are three interconnected interface, wherein, superposed two interfaces are respectively communicated with one Roof drain 10.So as to which two roof drains 10 have connected the gutter 90 of four water catchment areas, and roof drain 10 and rain pipe 70 are hidden completely In structure, only in gutter side, dew has the opening of double-edged fine-toothed comb 3.

In the present embodiment, rainwater is imported in the inflow rain pipe 70 that roof drain 10 is smoothed out by tail pipe 4, similar to side formula into Water roof drain.Rainwater fluidised form can be divided into following three kinds of situations：

At initial stage rainfall duration, when rainfall is smaller, when rainwater does not flood entire 10 water inlet of roof drain, rainwater enters rain After bucket 10, rain pipe 70 is fallen into from tail pipe 4 by rainwater, has the air gap in roof drain 10 and rain pipe 70, for gas Gas-liquid two-phase liquid, at this moment storm-water system belong to gravity flow system.

When occurring compared with torrential rain, water level is higher in gutter 90, and the water inlet of entire roof drain 10 is flooded by rainwater, rainwater Rainwater is full of in bucket 10 and rain pipe 70, air capacity is considerably less.At this moment storm-water system be pressure current, the head of entire storm-water system Loss is equal to the height difference of rainwater liquid level in gutter 90 to the free surface of the last outlet of system.

Gas is also when rainwater liquid level has just flooded 10 water inlet of roof drain in gutter 90, in roof drain 10 and rain pipe 70 It is not completely exhausted out, storm-water system is in the state of half pressure flow, belongs to pressure flow and the transient state of gravity stream.

Compared with traditional roof drain is installed, the utility model is applied to Shimizu concrete building construction, drainage system against rain structure Simply, pipeline connection is succinct, and the watershed of beam column both sides can link up, and improve the safe and reliable journey of drainage system Degree.Pipeline is imbedded in structure completely, maintains the uniformity of Shimizu concrete building construction style.

Each embodiment is described by the way of progressive in this specification, the highlights of each of the examples are with other The difference of embodiment, just to refer each other for identical similar portion between each embodiment.For system disclosed in embodiment For, due to corresponding to the methods disclosed in the examples, so description is fairly simple, related part is referring to method part illustration .

Foregoing description is only the description to the utility model preferred embodiment, not to any limit of the scope of the utility model Calmly, any change, the modification that the those of ordinary skill in the utility model field does according to the disclosure above content, belonging to right will Seek the protection domain of book.
