Abstract

The utility model discloses a leakage preventing prefabricated plate. One side edge of a plate body of the utility model is provided with a side plate which is of a forked tail shape and is upwards buckled, the other side edge of the plate body is provided with a downwards buckled side plate dovetailing with the upwards buckled side plate, one end edge of the plate body is provided with an end plate which is of a forked tail shape and is upwards buckled, and the other end edge of the plate body is provided with a downwards buckled end plate dovetailing with the upwards buckled end plate. When the utility model is installed, the upwards buckled side plate and the downwards buckled side plate and the upwards buckled end plate and the downwards buckled end plate are buckled and connected, and gap openings are filled with water proofing asphalt. The utility model can thorough prevent roof from leakage and has a good infiltration and leakage preventing effect, and the utility model has the advantages of convenient installation and operation and low construction cost.

Description

Du is leaked precast plate

The utility model relates to the building roofing floor, and specifically a kind of Du is leaked precast plate.

At present, the building roofing seepage is a great problem that building trade is generally acknowledged always, is a main cause that has a strong impact on the construction project quality.Generally big, medium-sized flat roof deck roof of buildings is to piece together lid with the prefabricated plate that the mixed earth of reinforcing bar is made to form, smear seam at the splicing sealing place of prefabricated plate with grout filling again and prevent drain process, though this common roof leakage processing method can prevent roof leakage for the moment, but, time is long slightly owing to be subjected to seasonal temperature to change the influence of expanding with heat and contract with cold, splicing sealing place at prefabricated plate easily cracks, still the roof leakage phenomenon can take place, for further improving the roof leakage performance, building trade is released the method that re-lays the flexible web waterproof on flat roof deck again, for example: alternately lay the multilayer asbestos at roofing, waterproofing materialss such as pitch, though this method has leak preventing effect preferably, but this method troublesome poeration, operating expenses is higher, main is the waterproofing materials poor durability of being laid, and the time has been grown easy aged deterioration and cracked, and still can not thoroughly stop roof leakage, in case roofing generation seepage, it is higher to keep in repair comparatively complexity and maintenance cost.

The purpose of this utility model is to propose a kind of Du with antiseepage seal structure on the basis of existing technology to leak precast plate.

The purpose of this utility model realizes by following technical solution:

A kind of Du is leaked precast plate, it has the plate body in sound insulation hole in being, done at a side of plate body and to have detained side plate, the section of last button side plate is swallow-tail form, another side of plate body do with on the following button side plate that matches of shape of button side plate, during installation, going up the button side plate and detaining the mutual snapping of side plate down between Du's leakage precast plate is again with floating the getting final product of water proofing asphalt filling sealing.

The utility model also has following technical characterictic:

The end of thread plate has been done on the plate body one end limit of leaking precast plate Du, the section of last end of thread plate is swallow-tail form, do the following end of thread plate that the shape with last end of thread plate matches on the other end limit of plate body, during installation, Du is leaked the last end of thread plate and the mutual snapping of following end of thread plate between the precast plate, with floating the getting final product of water proofing asphalt filling sealing.

The utility model is to have done the button side plate respectively and detained side plate down at the dual-side of plate body, and the limit, two ends has been done end of thread plate and following end of thread plate, mutual snapping during installation respectively, again with floating the getting final product of water proofing asphalt filling sealing, good antiseepage leak preventing effect is arranged, and easy to install, operating expenses is low.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the A-A sectional drawing of Fig. 1;

Fig. 3 is a user mode schematic diagram of the present utility model.

Below in conjunction with accompanying drawing the utility model is further described:

A kind of Du is leaked precast plate, it has the plate body 1 in sound insulation hole 2 in being, a side of plate body 1 do section be swallow-tail form on the button side plate 3, another side of plate body 1 do with on the following button side plate 4 that matches of shape of button side plate 3, an end limit of plate body 1 do section be swallow-tail form on end of thread plate 6, do the following end of thread plate 5 that the shape with last end of thread plate 6 matches on the other end limit of plate body 1, to shut out when Lou precast plate is installed on the building 8, going up button side plate 3 and detaining side plate 4 mutual snappings down between Du's leakage precast plate, last end of thread plate 6 and following end of thread plate 5 mutual snappings, the filling sealing is floating gets final product for usefulness water proofing asphalt 7 again.The utility model is skillfully constructed, and is reasonable in design, has good antiseepage leak preventing effect, can thoroughly stop the building roofing seepage after installing and using, and easy for installation, and operating expenses is low, has obvious social and economic benefit.
