Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example (b):

a precast concrete slab capable of draining water in time refers to fig. 1 and 2, and comprises a cross beam 1 and two rib beams 2 which are positioned at the lower end of the cross beam 1 and used for supporting the cross beam 1, wherein the rib beams 2 are arranged along the length direction of the cross beam 1 to support the cross beam 1 and play a role in bearing load; the thickness at both ends of crossbeam 1 is less than the thickness in the middle to form the high inclined plane that both ends are low in the middle, be convenient for make ponding discharge along the inclined plane of crossbeam 1.

Referring to fig. 1, limiting plates 4 are poured around a cross beam 1 through concrete, each limiting plate 4 comprises a first limiting plate 5 and a second limiting plate 6, and the first limiting plate 5 is higher than the second limiting plate 6; and a diversion angle 7 is respectively poured on the lower surface of the beam 1 and under the two second limiting plates 6, so that accumulated water flowing from the inclined surface of the beam 1 to the two ends is discharged from the second limiting plates 6 and drops downwards along the diversion angle 7.

Referring to fig. 1, two water collection tanks 8 have been seted up to crossbeam 1 upper surface, are provided with first water conservancy diversion face 9 on every water collection tank 8 keeps away from the inside wall of second limiting plate 6 respectively, and first water conservancy diversion face 9 inclines along the rivers direction, is convenient for make ponding flow into water collection tank 8 along 1 inclined plane of crossbeam fast.

Referring to fig. 2 and 3, a first drainage hole 10 is respectively formed in the bottom wall of each water collecting tank 8; the first drainage hole 10 penetrates through the cross beam 1 along the thickness direction of the cross beam 1; the bottom wall of each water collecting tank 8 inclines towards the first drainage hole 10, so that water in the water collecting tank 8 is conveniently concentrated and gathered at the first drainage hole 10, and the drainage speed is accelerated; the second wash port 13 has been seted up to 8 diapalls of water catch bowl and the one end that is located first wash port 10, and second wash port 13 slant runs through crossbeam 1 and link up mutually with the inside wall in first wash port 10 to the ponding that the drainage is located 8 diapalls of water catch bowl and is less than first wash port 10 position.

Referring to fig. 3, mounting grooves 12 are respectively formed in the lower surface of the cross beam 1 and at the two first drainage holes 10, and the mounting grooves 12 are communicated with the lower ends of the first drainage holes 10, so that a drainage pipe (not shown) is additionally arranged in the later mounting groove 12 in an adhesive manner, and the first drainage holes 10 are inserted into the drainage pipe; an abutting plug 14 is inserted into the mounting groove 12; impurities such as dust and the like are prevented from blocking the mounting groove 12 to influence the mounting of a subsequent water pipe; the butt stopper 14 lateral wall is provided with two recessed surfaces 15 of stepping down to operating personnel from recessed surface 15 department of stepping down will butt stopper 14 fill in mounting groove 12 fast conveniently.

The working principle is as follows:

the concrete flat plate is erected on a roof, when water is accumulated on the concrete flat plate, the accumulated water flows into the water collecting grooves 8 at two ends along the inclined plane with the high middle part and the low two ends of the cross beam 1, and the inclined bottom wall structure of the water collecting grooves 8 enables the accumulated water to be concentrated at the first drainage hole 10 and to be discharged from the first drainage hole 10; when ponding is too much and spill over the water catch bowl 8, ponding flows out from second limiting plate 6 to along the downward drippage of water conservancy diversion angle 7, thereby finally reach the purpose that the concrete slab can sluiced fast.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
