Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a drain body fixing device applied to a deck plate foundation heat insulating roof construction method.
[0002]
[Prior art]
There is known a deck plate base heat insulating roof construction method in which a roof is formed by laying a heat insulating plate on a deck plate and further waterproofing the heat insulating plate.
[0003]
Since the roof formed by this construction method is a substantially flat land roof surrounded by parapets, a roof drain for rainwater drainage is installed on the roof.
[0004]
However, up to now, almost no roof drain dedicated to such a method has been manufactured, and therefore, a concrete-driving type roof drain is conveniently used for the construction of the roof by this method.
[0005]
As shown in FIG. 9, the concrete driving type roof drain a is bent in a substantially L shape on the back surface of the drain receiving tray c of the drain body b composed of the drain receiving tray c and the drain pipe portion d. A plurality of anchors e are provided. In order to construct the roof drain a, first, a loose fitting hole g through which the drain pipe portion d of the drain main body b can be inserted is drilled in the deck plate f, and then the cross section of the loose fitting hole g on the bottom surface of the hole is substantially omitted. The upper edge of the annular receiving metal h having an L shape is welded. Next, the drain main body b is inserted into the loose fitting hole g from above and the anchor e is mounted on the receiving metal h, whereby the drain main body b is held at a predetermined height position. In this state, a heat insulating plate j is laid on the surrounding deck plate f excluding the drain body b, and a sheet waterproof layer k is further laid on the heat insulating plate j, and the edge of the sheet waterproof layer k is drained. The construction is performed by sandwiching between the upper surface of the tray c and the waterproof layer presser m.
[0006]
[Problems to be solved by the invention]
By the way, in the above-mentioned construction, there is a problem that the anchor e on the back surface of the drain tray c is only mounted on the metal fitting h, and the drain body b cannot be fixed. For this reason, when the drain main body b is attached to the female screw portion n formed on the inner periphery of the drain pipe portion d after the drain main body b is installed, the drain main body b is attached. Oscillates and makes the screwing operation difficult. Further, there is a problem that the upper end of the soot pipe p is not stable even after the soot pipe p is attached.
[0007]
An object of the present invention is to provide a drain body fixing device capable of solving such conventional problems.
[0008]
[Means for Solving the Problems]
The present invention comprises a drain pan and a drain pipe portion coupled downward from the drain pan, and fixes the drain body disposed on the deck plate, and is provided on the back surface of the drain pan. The drain body fixing device is characterized in that a support member extending from the periphery of the drain tray and fixed to the upper surface of the deck plate is directly fixed.
[0009]
Here, the drain body is formed for vertical drainage, and the fixing device can be applied to the drain body for vertical drainage.
[0010]
In such a configuration, with the support member fixed directly to the back surface of the drain tray, the drain body extends from the periphery of the drain tray by inserting the drain body from above into a loose-fitting hole previously formed in the deck plate. The support member comes into contact with the upper surface of the deck plate, and the drain main body is held at a predetermined height position. In this state, the drain body can be easily fixed by fixing the support member to the upper surface of the deck plate by fixing means such as screws or welding.
[0011]
As a means for fixing the support member to the drain tray, a configuration in which the support member is fixed to a screw hole formed on the back surface of the drain tray with a screw may be proposed. Thus, if the support member is screwed to the back surface of the drain pan, the product can be packed with the support member removed from the drain pan at the time of product shipment. Can be easily installed. Here, in the driving-type roof drain, a plurality of screw holes for screwing the anchor e (see FIG. 9) are formed in advance on the back surface of the drain tray, so that the screw holes are used. Thus, if the support member is screwed to the back surface of the drain pan, there is no need to separately process a screw hole in the drain pan.
[0012]
The present invention also includes a drain pan formed in a substantially L-shaped cross section by a horizontal edge portion and a vertical edge portion, and a drain pipe portion coupled backward from the vertical edge portion of the drain tray. A drain body disposed at a corner portion where a horizontal deck plate and a vertical wall surface intersect with each other, the deck extending from the periphery of the drain tray to the back surface of the drain tray The drain body fixing device is characterized in that the supporting members fixed to the upper surface and the wall surface of the plate are directly fixed.
[0013]
Here, the drain main body is formed for horizontal drainage, and the fixing device is configured to be applicable to the drain main body for horizontal drainage.
[0014]
In such a configuration, with the support member fixed directly to the back surface of the drain pan, the drain pan of the drain body is inserted from the front into a loose fitting hole formed in advance on the wall surface of the corner portion. A support member extending from the peripheral edge of the plate abuts against the upper surface and the wall surface of the deck plate, and the drain main body is held at a predetermined position. In this state, the drain body can be easily fixed by fixing the support member to the upper surface and the wall surface of the deck plate by fixing means such as screws or welding.
[0015]
Further, as a means for fixing the support member to the drain tray, a configuration in which the support member is fixed to a screw hole formed on the back surface of the drain tray by a screw may be proposed. Thereby, various effects as described above can be obtained.
