DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temporary fixing device for a drain body applied to a deck plate method.

[0002]

2. Description of the Related Art There is a construction method called a deck plate method in which a roof drain body is buried in concrete poured on a deck plate and the drain body is fixed.

As a temporary fixing device for the drain body used in this method, as disclosed in Japanese Utility Model Publication No. 1-26826, the drain body is inserted into a loose fitting hole a formed in a deck plate p (see FIG. 13). And a mounting flange c provided around the upper edge thereof and locked to the upper surface of the deck plate p
And a cylindrical spacer h which is fitted on the drainage pipe portion f of the drain main body e, and is mounted on the upper surface of the driving fitting so as to surround the cylindrical hole g of the driving fitting d.
A connecting piece i that is attached to the drain body e from above and a connecting piece k that comes into contact with a locking edge j provided on the driving fitting d from below are detachably connected to each other, and the drain body e and the driving fitting d are connected to each other. Has been proposed by the present applicant.

In such a configuration, the drain body e and the driving fitting d are previously connected in a clamping manner by the connecting means m via a cylindrical spacer h, and the driving fitting d is fitted into the deck plate p. After drilling a loose fitting hole a, the concrete blocking cylinder b of the metal fitting d is fitted into the loose fitting hole a, and the mounting piece c is hung on the deck plate p around the hole to perform welding or the like. The connection body is temporarily fixed to the deck plate p by bolting. Next, concrete n is poured into the deck plate p and solidified.
The drain body e is fixed to the concrete n by removing the connecting means m and removing the connecting pieces i and j.

In such a configuration, the position of the drain body e can be accurately and optimally maintained without being affected by the state of the mounting position of the deck plate p. Further, since the construction at the site is almost completed by mounting the connecting body on the deck plate p and driving the concrete n, there is an advantage that the mounting construction can be performed quickly and easily.
