Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a rooftop waterproof joint through which pipe materials such as air conditioning liquid pipes and distribution pipes are inserted.

<Prior art> When pipe materials such as air conditioning liquid pipes and distribution pipes are connected to a tank installed on a rooftop, a roofed collection room called a dovecote is constructed on the rooftop, and the collection room is In addition, there is a system in which a large number of pipes run downward and branch pipes are pulled out in the middle of each pipe to provide necessary air conditioning control to each floor.
In this system, each pipe of the pigeon house and the tank are communicated with each other through a connecting pipe provided on the roof surface. By the way, such a pigeon coop is constructed by first forming the roof and then pouring and splicing, which is time-consuming as it is necessary to incorporate formwork and reinforcing bars, and further requires connecting pipes exposed on the roof. Therefore, there are disadvantages in construction, such as piping loss and damage.

Therefore, there is a construction method that uses a waterproof joint to directly pull out the pipe material to a position near the tank. This method has the technical difficulty of having to align the waterproof joint almost exactly with the pulling position of the pipe material, but
The drawbacks of pigeon coops listed above can be corrected.

<Problems to be solved by the invention> By the way, in the construction method using such a waterproof joint, the waterproof sheet y laid on the roof wall x,
It is necessary to hold it around the periphery of the waterproof joint.

If such retention is performed by known means,
The configuration is as shown in FIG.

That is, in this product, a screw rod b is erected on the upper surface of the seat holder flange a, a sheet presser c is inserted through the screw rod b, is mounted on the sheet holder flange a, and is projected onto the sheet holder c. A nut d is screwed into the threaded rod b and tightened, and the waterproof sheet y is held between the sheet receiving flange a and the sheet presser c.

By the way, with such a configuration, the screw rod b gets in the way and the edge of the waterproof sheet y is pushed against the sheet receiving flange a.
Therefore, it is not possible to insert the sheet deeply between the sheet pressers c. For this reason, the waterproofing of the roof wall x becomes insufficient.
In addition, since the waterproof sheet y is held between the sides of the screw rod b, the tightening pressure of the nut d is sufficient to hold the waterproof sheet y.
However, there are disadvantages such as the fact that the sheet y is likely to be insufficiently clamped.

The object of the present invention is to provide a waterproof sheet holding device that is suitable for roof-top waterproof joints and has the above-mentioned drawbacks corrected.

<Means for solving the problem> The present invention is a sheet protruding from the outer peripheral surface of the waterproof joint main body, which is inserted into the roof wall x in the vertical direction and embedded, and into which the pipe material passes. A receiving flange, locking protrusions protruding from the outer circumferential surface of the waterproof joint main body at predetermined intervals on the receiving flange, and a locking protrusion that is placed on the edge of the waterproof sheet laid on the sheet receiving flange. A fixation comprising a sheet presser and a bolt which is disposed between the sheet presser and the locking protrusion, and whose inner end abuts the lower surface of the locking protrusion and which presses against the upper end of the sheet presser and is screwed in the vertical direction. It is composed of a ring.

<Function> The waterproof sheet y is deeply interposed on the sheet receiving flange of the waterproof joint body, and furthermore, the sheet presser is mounted on it. When the bolts of the fixing ring are tightened and screwed together, the inner end of the fixing ring comes into pressure contact with the locking protrusion of the waterproof joint body from below, and the lower end of the bolt comes into contact with the upper end of the sheet presser. Therefore, the waterproof sheet is pressed into contact with the waterproof sheet y by applying pressure from directly above it.

<Embodiment> An embodiment of the present invention will be described with reference to the accompanying drawings.

Reference numeral 1 denotes a tubular waterproof joint body, with a sheet receiving flange 2 protruding outward from the middle thereof, and its upper and lower ends being squeezed to form an upper edge 3 and a lower edge 4;
An inner circumferential groove 5, which is the main part of the present invention, is provided in the waterproof joint main body 1 between the upper edges 3 and 4, each having an inner diameter that allows a pipe material 30 such as an air conditioning pipe material to be loosely inserted therein. The inner circumferential groove 5 is covered and shielded from the inside with a protective cover 6, and a liquid is injected into the liquid injection hole 4a formed in the lower edge 4, and a heat insulating material 7 such as polyurethane foam is injected into the inner circumferential groove 5. It's filling.

Note that if the pipe material 30 passing through the waterproof joint body 1 is of a type that does not require heat insulation treatment, such as a distribution pipe, there is no need to fill the inner circumferential groove 5 with a heat insulating material. . Furthermore, the structure of the waterproof joint body 1 may be such that the inner circumferential groove 5 is not provided.

The upper end edge 3 has an inner circumferential surface with an upwardly expanding slope, so that an annular packing 14 having a wedge-shaped cross section can be fitted between the tube member 30 and the upper end edge 3, as will be described later. Further, a male screw is provided on the outer periphery of the upper edge 3.

The waterproof joint main body 1 having the above-mentioned configuration has a roof wall x
When constructing the rooftop wall x, the sheet receiving flange 2 is inserted and embedded in the required position vertically, and the upper surface of the sheet receiving flange 2 is exposed from the rooftop wall x. A waterproof sheet y is placed on the sheet receiving flange 2, and a caulking material 9 is supplied between the end portion of the waterproof sheet y and one circumference of the waterproof joint main body for waterproofing.

Next, a waterproof sheet holding device, which is a main part of the present invention, will be explained.

On the waterproof sheet y is an annular sheet presser 1 having an L-shaped cross section and having a rubber gasket 10a on the lower surface.
0 is loaded. The upper end of the sheet presser 10 is
Receiving groove surface 10 for abutment of a bolt 12 to be described later
b is formed.

Furthermore, locking protrusions 8 are protruded from the outer peripheral surface of the waterproof joint main body 1 at predetermined intervals.

Furthermore, a fixing ring 11 is arranged between the receiving groove surfaces 10b of the locking protrusion 8, and the fixing ring 11
At the inner end of the locking projection 8, locking protrusions 11a that abut the locking protrusions above and below are provided at equal intervals from the locking protrusions 8. Further, screw holes 11b are formed in the fixing ring 11 at predetermined intervals, and the screw holes 11b are formed at predetermined intervals.
A bolt 12 is screwed into.

After rotating the fixing ring 11 so that the locking protrusion 11a and the locking protrusion 8 are aligned vertically, the lower end of the bolt 12 is inserted into the receiving groove surface 10 of the sheet presser 10.
When the user gets on the vehicle and screws the bolt, the fixing ring 11 rises relative to the bolt 12, and the locking tip 1
1 a comes into contact with the lower surface of the locking protrusion 8 . When the bolts 12 are further tightened, the waterproof sheet y is pressed against the upper surface of the sheet receiving flange 2 by the lower surface of the sheet presser 10. Therefore, the waterproof sheet y is securely held,
This prevents it from rising.

After inserting the pipe material 30 into the waterproof joint main body 1, an annular packing 14 is fitted between the inner surface of the upper edge 3 and the outer circumference of the pipe material 30, and further the upper edge 3
The waterproof cover 15 is screwed onto a screw formed on the outer periphery of the waterproof cover 15.

The waterproof cover 15 has an inverted cup shape,
A through hole 16 is formed in the center base, and after passing the pipe material 30 inserted into the waterproof joint main body 1 through the through hole 16, a female screw 17 is attached to the outer periphery of the upper edge 3.
are screwed together and connected on the waterproof joint main body 1.
In such a connected state, the cover portion 18 on the periphery hangs down to the outside of the sheet presser 10 and the fixing ring 11 to cover them. Further, a protrusion 19 for receiving caulking is provided on the upper part of the waterproof cover 15,
A caulking material 20 is supplied between the inner surface of the protrusion 19 and the outer periphery of the tube material 30. When the waterproof cover 15 is in the tightened state, the upper wall of the cover 15 comes into contact with the annular gasket 14 .

In the above configuration, the caulking material 20 and the annular packing 14 prevent raindrops from leaking between the pipe material 30 and the heat insulating material 7. In addition, the waterproof cover 1
The cover portion 18 and the caulking material 9 of No. 5 prevent raindrops from entering from the sides.

In addition, 25 is a sleeve, roof wall x
This is to correct the unevenness between the wall thickness of the waterproof joint body 1 and the length of the waterproof joint body 1, thereby providing versatility to the waterproof joint body 1.

The above embodiment is applied to a non-pedestrian rooftop where no one rides on the rooftop.

In the case of constructing a rooftop surface for pedestrians, the covering part 18 of the waterproof cover 15 is omitted, and a cinder concrete layer and a finishing material layer are sequentially added on top of the waterproof sheet y laid on the rooftop wall x. It is formed. This point is different from the construction of the non-walking rooftop, but the construction can be performed in the same manner in other respects. The waterproof sheet holding device can also be applied to a waterproof joint installed on a rooftop surface for walking.

<Effects of the invention> As described above, in the present invention, since there are no obstructions such as bolts between the sheet receiving flange 2 of the waterproof joint body 1 and the sheet presser 10, the edge of the waterproof sheet y can be deeply interposed. Therefore, water leakage from between the waterproof sheet y and the sheet receiving collar 2 can be prevented as much as possible. Further, since the sheet presser 10 is pressurized by a bolt from directly above it, the pressing force against the waterproof sheet y is large. Therefore, the waterproof sheet y has excellent effects such as reinforcing the waterproof ability.
