Abstract
The utility model belongs to a prefabricated floor slab, mainly solving the problem of water leakage of a slit between the prefabricated floor slabs. The utility model is characterized in that the utility model comprises the prefabricated floor slab whose one side is provided with an outwards convex water channel and the other side is provided with an outwards extended cover slab of the water channel. Leaked water flows into the water channel from the interior of the slit of the upper part between the prefabricated floor slabs is drained through a drain system, and the leaked water can not flow to a position under the floor slab from the slit of the lower part; in addition, the floor top does not need to be treated in the mode of three-oil and three-coating. The utility model has the advantages of simple structure, leakage resistance, and floor top manufacturing cost saving.
Description
The utility model relates to a kind of precast floor slab, and the particularly a kind of slit of the ponding on the floor between floor that prevent flows to the precast floor slab of underfloor.
Existing precast floor slab mostly is made of the cuboid plate that contains some through holes, its weak point is that the outside of precast floor slab is not provided with tank or tank cover plate, thereby, there are the slit between precast floor slab all the time in roof that is made of some precast floor slabs or ground, when having ponding on roof or the ground, just have part ponding and leak into the below of precast floor slab from this slit, make troubles for the resident living of living in the below and cause certain loss by the application of anti-leakage layers damaged.In addition, existing roof need carry out three oily three felts to be handled, and manufacturing cost is increased.
The purpose of this utility model is exactly to provide a kind of the water that oozes down from slit between precast floor slab to be got rid of at above-mentioned weak point, makes the leakproof precast floor slab of this infiltration stream less than the floor below.
Technical solution of the present utility model is: a kind of leakproof precast floor slab, comprise precast floor slab, and it is characterized in that: be provided with the tank of outside protrusion in a side of described precast floor slab, opposite side is provided with outwardly directed tank cover plate.
Tank section described in the utility model technical solution can be for trapezoidal.
The side of the tank cover plate described in the utility model technical solution and the angle between the base are 75 °～80 °, and the precast floor slab side and the angle between the base of tank top are 75 °～80 °.
The utility model is owing to be respectively equipped with tank and tank cover plate in the both sides of precast floor slab, thereby in use, the tank cover plate and the tank of two adjacent precast floor slabs match, simultaneously on the crossbeam of load precast floor slab, be provided with tank, therefore, damaged and when ponding is arranged when the application of anti-leakage layers of roof, just have of the slit infiltration of part ponding from top between the precast floor slab, and flow in the tank of precast floor slab, flow into again in the crossbeam tank at tank two ends after how amassing, discharge by drainage channel at last.This part infiltration is just no longer flowed out from the slit of lower part between the precast floor slab, thereby has fundamentally solved the seepage problem of precast floor slab, removed precast floor slab below resident because of infiltration to its worry of bringing, also reached the purpose of this utility model.Owing to only need processing such as jointing between precast floor slab, and do not need three oily three felts to handle, therefore can reduce manufacturing cost.Because the cross section of precast floor slab tank can be for trapezoidal, therefore, delivery is comparatively convenient in the mill.Because the angle between precast floor slab tank cover plate side and the base can be 75 °～80 °, between the precast floor slab side of tank top and the base angle be 75 °～80 °, therefore, precast floor slab butt joint back forms the wedge groove, is convenient to construction and jointing.
The drawing of accompanying drawing is described as follows:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a crossbeam section structure schematic diagram.
The utility model is described in further detail below in conjunction with accompanying drawing: as shown in Figure 1 and Figure 2, the middle part of precast floor slab 2 is identical with common precast floor slab.The section of tank 3 is convenient to delivery in the mill for trapezoidal.Flume wall and precast floor slab 2 are connected as a single entity.The height of tank 3 account for flume wall high 1/2, the flume wall height accounts for 2/3 of precast floor slab 2 thickness.Tank cover plate 1 is connected as a single entity with precast floor slab 2, and it highly accounts for 1/3 of precast floor slab 2 thickness.Tank cover plate 1 matches with tank 2 and flume wall.The side of tank cover plate 1 and the angle on base are 75 °～80 °, and precast floor slab 2 sides and the angle between the base of tank 3 tops also are 75 °～80 °, and therefore, the top in the construction between the precast floor slab 2 forms wedge, but convenient construction and jointing like this.The upper central of crossbeam 4 is provided with tank 5.In use, crossbeam 4 is used to support precast floor slab 2, and like this, the two ends of tank 3 just in time is in the top of tank 5, and tank 3 is vertical mutually with tank 5, and therefore, the infiltration in the tank 3 just can flow in the tank 5, discharges through the drainage system of tank 5 terminations again.
