Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1, in this embodiment, a water-proof structure for a drain pipe and a floor slab hanging hole includes a floor slab 1 and a drain pipe 2 installed in the floor slab hanging hole, the drain pipe 2 is provided with a water-stop ring 3 attached to a lower surface of the floor slab 1 for blocking a bottom end of the hanging hole, the hanging hole is composed of an upper section and a lower section, a lower section of the hanging hole is a straight hole, an upper section of the hanging hole is a bell mouth 4, a grouting layer 5 wrapped on an outer peripheral surface of the drain pipe 2 is provided in the straight hole, an upper surface of the grouting layer 5 is lower than a top end surface of the straight hole to form a certain height difference with the bell mouth, a first leakage-blocking layer 6, a cement mortar layer 7 and a cement-based water-proof layer 8 are sequentially provided on the grouting layer 5 and around the drain pipe 2 from bottom to top, and an upper surface of the first leakage-blocking layer 6 is flush with an upper surface of the floor slab 1.
In the utility model, the water stop ring 3 which is attached to the lower surface of the floor slab 1 is arranged on the drain pipe 2 and is used for plugging the bottom end of the hanging hole (namely plugging the lower surface of the floor slab), so that when the grouting layer 5 is poured into the hanging hole, the grouting layer is prevented from leaking from the bottom end of the hanging hole to influence the forming of the grouting layer, the traditional hanging hole template is replaced, time, labor and money are saved, and the hanging hole template is not required to be dismantled in the later period. The hanging hole consists of an upper section and a lower section, the lower section of the hanging hole is a straight hole, and the upper section of the hanging hole is a bell mouth, so that the leak stopping layer 6 is in close contact with the floor slab 1. The upper surface of the grouting layer 5 is lower than the top end face of the hanging hole, and a certain height difference is formed between the upper surface of the grouting layer 5 and the top end face of the hanging hole, so that the grouting layer 5 is in close contact with the first leakage blocking layer 6 conveniently. On grout layer 5 and drain pipe 2 is all around by supreme first leaking stoppage layer 6, cement mortar layer 7 and the cement base waterproof layer 8 of setting gradually down, through the setting of cement mortar layer and cement base waterproof layer, to the seam crossing that drain pipe 2 was wrapped up by first leaking stoppage layer 6 form the protection once more, avoid here the seepage condition to appear. Thereby effectively solving the problem that the joint of the drain pipe and the floor slab hanging hole is leaked.
In the scheme, the grouting layer 5 is a grouting material, the grouting material takes a high-strength material as an aggregate, cement as a bonding agent, and the grouting material has the characteristics of no shrinkage, micro expansion, no aging, no pollution to water quality and the surrounding environment, good self-sealing property and the like, and has the advantages of reliable quality, low cost, convenience in use and the like in the aspect of construction, so that the grouting material is adopted as a first layer structure for installing and fixing the drainage pipe and the floor slab hanging hole and preventing seepage. The first leakage stopping layer 6 is a leakage stopping king which integrates inorganic, alkali-free, waterproof, moistureproof, anti-seepage and leakage stopping, can be quickly solidified, and has the density and the strength far higher than those of the existing high-grade concrete, so that the leakage stopping king is used as a second layer structure for installing and fixing the drainage pipe and the floor slab hanging hole and preventing seepage.
In this embodiment, the water stop ring 3 is an annular boss structure composed of an upper ring plate and a lower ring plate, a through hole matched with the outer diameter of the drain pipe 2 is formed in the water stop ring axis, a counter bore is formed in the upper ring plate axis, and the diameter of the counter bore is larger than that of the hanging hole, so that a cavity for accommodating the partial grouting layer 5 is formed on the lower surface of the floor slab 1.
The annular boss structure that the water stop ring 3 adopts the upper and lower crown plate to constitute supports the upper ring plate through tightly tightening the lower crown plate on drain pipe 2, makes the upper ring plate upper surface closely laminate with 1 lower surface of floor to carry out the shutoff to hanging hole bottom, prevent to leak thick liquid. Through set up the counter bore on the upper ring plate axis, and the counter bore diameter is greater than and hangs the hole diameter, when hanging the hole in the pouring grout layer 5, the grout layer 5 after condensing forms annular arch on floor lower surface, and its vertical plane is the style of calligraphy of falling T. The annular bulge of the grouting layer replaces the existing hanging hole template, the structure of the existing hanging hole after plugging is changed, and the bonding surface of the grouting layer and the lower surface of the floor slab is increased, so that the leakage of the joint of the drain pipe and the hanging hole of the floor slab is further prevented.
In this embodiment, the upper surface of the cement mortar layer 7 is a concave arc surface to form an R-angle treatment at the inner corner of the upper surface of the drain pipe 2 and the first leakage blocking layer 6, and the cement-based waterproof layer 8 is an arc surface corresponding to the upper surface of the cement mortar layer 7.
Like this, carry out R angle through cement mortar layer 7 to drain pipe 2 and the first leaking stoppage layer 6 upper surface reentrant corner department and handle to form the one deck protection to it, rethread cement base waterproof layer 8 protects cement mortar layer parcel drain pipe and seam crossing, further prevents the seepage.
In this embodiment, the cement mortar layer 7 completely covers the upper surface of the first leakage blocking layer 6 and extends outward, and the cement-based waterproof layer 8 completely covers the upper surface of the cement mortar layer and extends outward.
Like this, pack the horn mouth through first leaking stoppage layer 6, flush the back with the floor upper surface, can protect the edge of horn mouth once more, avoid water to appear the seepage from the horn mouth edge.
In the present embodiment, a second leakage blocking layer 9 is provided between the cement mortar layer 7 and the cement-based waterproof layer 8.
The second leaking stoppage layer 9 also adopts the leaking stoppage king, and according to the characteristics of the leaking stoppage king, the upper surface of the cement mortar layer 7 subjected to the R angle treatment is coated with the leaking stoppage king to form a layer of protection again, so that the leakage is further prevented.
In the present embodiment, the side surface of the bell mouth 4 is roughened.
Therefore, the horn mouth 4 on the floor slab 1 is more firmly adhered to the first leaking stoppage layer 6, and water is prevented from leaking between the horn mouth of the floor slab and the first leaking stoppage layer.
Finally, it is noted that the above-mentioned embodiments illustrate rather than limit the utility model, and that, while the utility model has been described with reference to preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the utility model as defined by the appended claims.
