Abstract

(57) [Summary] [PROBLEMS] To prevent concrete from leaking from the periphery of a drain body when pouring concrete into a deck plate. When a drain body (10) is assembled and fixed to a deck plate (20), an annular body (23) preliminarily wrapped around the outer periphery of a lower spacer (6) punches a part of the deck plate (20). By being interposed between the hole 22 and the lower spacer 6 in a compressed state, it is possible to prevent the concrete from leaking downward.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a roof drain device which is installed as a drainage means when a slab concrete is cast on a deck plate (corrugated steel roof), and particularly to a roof drain fixing device for a deck plate.

[0002]

[Prior art]

 A roof drain fixing device for a deck plate is generally known from, for example, Japanese Utility Model Publication No. 1-282626. As shown in FIG. 4, in this conventional apparatus, a lower spacer 52 penetrating a hole 51 formed by punching a part of a deck plate 50, and a fixing plate 53 installed on the deck plate 50 are provided. A presser plate 57 for externally fitting the drainage port 55 of the drain body 54 and attaching to the upper surface of the fixing plate 53; A connecting piece 59, which comes into contact with a locking edge 58 provided on the metal fitting from below, is connected with a connecting bolt / nut 60/61, and the drain main body 54 and the metal fitting are clamped via a spacer 56, and the drain main body 54 is There is known one that is fixed.

[0003]

[Problems to be solved by the invention]

 In this type of fixing device, a lower spacer 52 is fitted into a hole 51 formed by punching a part of a deck plate 50, and a fixing plate 53 is placed on the deck plate 50 in the hole. By welding, the drain body 54 is set on the deck plate 50. Next, a slab concrete 62 is cast on the deck plate 50.

At this time, in the fixing device, a gap is formed between the periphery of the lower spacer 52 and the hole 51, and there is a possibility that the slab concrete 62 leaks downward, that is, downstairs. Therefore, the gap has to be shielded with a gum tape or the like.

[0005]

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a drain body 10 integrally having a saucer portion 1 and a drainage port 3 opened at a bottom portion 2 of the saucer portion. Is mounted on the fixed plate 5 installed on the deck plate 20 via the short cylindrical spacer 4, and the lower end of the fixed plate 5 faces downward through the deck plate 20. By providing a short cylindrical lower spacer 6 integrally so as to open to the bottom, the drain main body 10 is connected to the lower spacer 6 and the presser plate 7 fitted to the drain main body receiving portion 1. In a roof drain device in which the slab concrete 21 is cast on the deck plate 20 after being fastened and fixed by the connecting bolts / nuts 11 and 12 between the lower spacers 6, The ring body 23 is wrapped around Preparative Le - - des Kkipure wherein a Fudoren fixation device.

In such a configuration, when the slab concrete is cast on the deck plate 20, the lower space is provided between the lower spacer 6 and the hole 22 formed by punching a part of the deck plate 20. The ring body 23, which is circumferentially attached to the outer periphery of the hole, is interposed in a compressed state, so that even if there are irregularities on the periphery of the hole 22, the irregularities are absorbed by the ring body 23. Can be. As a result, a gap due to the irregularities does not occur, and it is possible to prevent the concrete from flowing out of the gap.

[0007]

[Embodiment of the invention]

 Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 shows a state in which a roof drain is mounted and fixed on a deck plate, and FIG. 3 shows a state after completion. 1 and 3, reference numeral 10 denotes a drain body, which is integrally provided with a saucer portion 1 having an open-topped disk shape and a drain port 3 projecting downward from a bottom portion 2 thereof. A holding plate 7 also serving as a protective cover is fitted into the pan opening portion. The drainage pipe opening 3 is tapered as a drain pipe so that the drainage pipe can be externally fitted and connected when the construction is completed (Fig. 3). In addition, there may be a case of an inner fitting connection. In this case, a taper screw (not shown) is provided on the inner peripheral surface of the pipe opening.

In FIG. 1 and FIG. 3, reference numeral 20 denotes a deck plate, and the drain device is provided at a draining position of the deck plate. A hole 22 is made by punching a part of the deck plate 20, and a fixing plate 5 is installed so as to close the hole, and a short cylindrical spacer 4 is integrally mounted on the fixing plate 5. . A hole 24 of the same size as the spacer is formed in the spacer 4 mounting position on the fixed plate surface. Then, the drain main body 10 is fitted and installed on the upper part of the spacer 4. A cylindrical lower spacer 6 having a larger diameter than the spacer 4 is integrally attached to a lower portion of the fixing plate 5. The drain body 10, the drain port 3, the hole 24 of the fixing plate 5, the hole 22 of the deck plate 20, and the lower spacer 6 are set concentrically. For the annular body 23 on the outer periphery of the lower spacer 6, an elastic material made of an elastic rubber or a sponge, which is wrapped around with a double-sided tape, an adhesive or the like, can be suitably used.

The connection bolt 11 is long enough to penetrate through the holding plate 7 and be inserted into the inside of the drain body 10. The connection bolt 11 is fitted with a nut 12 such as a wing nut from the upper end, and the pivot stopper 9 is attached to the lower end. Mounted integrally. Two or more locking rods 8 formed by bending a strip of fixed width are attached to the pivot stopper 9 at equal circumferential intervals.

[0010]

[Action]

 As shown in FIG. 1, the fixing plate 5, the upper spacer 4, and the drain main body 10 are fitted on the deck plate 20, and the connection bolt 11 is closed from the upper part of the drain main body 10 at the lower end in a hanging manner. Inserting the locking rod 8 in the state, with the tip of the locking rod facing the lower edge of the lower spacer 6, and screwing the nut 12, the connecting bolt 11 is gradually pulled up. When the retainer is locked to the lower end edge and further tightened, the drain body 10 is fixed on the fixing plate 5 via the upper spacer 4 and the lower spacer 6 by pulling the holding plate 7 and the locking rod 8.

When mortar is poured onto deck plate 20 in this state, slab concrete 21 flows around lower spacer 6. Even in such a state, the outflow of the concrete can be prevented by the annular body 23 downward. When the slab concrete 21 has been dried and solidified, the nut 12 of the bolt 11 is loosened, and the pivot stopper 9 and the locking rod 8 are removed. Thereafter, the strainer 25 is attached to the drain body 10. (Fig. 3)

[0012]

[Effect of the invention]

 Since the present invention is configured as described above, when the drain main body 10 is assembled and fixed to the deck plate 20, the ring body 23, which is preliminarily wrapped around the outer periphery of the lower spacer 6, is used. By being interposed in a compressed state between the hole 22 from which a part of the hole 20 is punched and the lower spacer 6, even if there are irregularities on the periphery of the hole 22, the irregularities are removed. 23 can be absorbed. Accordingly, a gap due to the unevenness does not occur, and the slab concrete 21 from the gap can be prevented from leaking downward, that is, downstairs. In addition, there is no need to shield the gap with a conventional gum tape or the like, and the work can be performed smoothly, smoothly, and efficiently.
