DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drain mounting apparatus for draining a concrete surface which is cast on a plate having a predetermined unevenness.

[0002]

2. Description of the Related Art It is common practice to cast concrete on corrugated plate-shaped structural material commonly referred to as a deck plate and use it as a floor, a roof, or the like. Takes a lot of trouble. In the conventional method, a short cylindrical sleeve is interposed at the lower end of the drain port of the drain body, and the fixing bracket is fixed with a long screw bolt or the like, and then placed around the drain mounting hole on the plate surface. It is a method of welding concrete or attaching it with a tapping screw and casting concrete while covering the drain port.

[0003] This method requires many setups,
In addition, there is a problem in that work such as welding is also required, which requires extra work. On the other hand, actual fairness 1
No. 26826 proposes a device for fixing a roof drain, but it does not require welding or threading, but the procedure for assembling the components is difficult, and it is difficult to change it especially when it is desired to change the thickness of concrete. was there.

[0006]

FIG. 1 is an exploded view of an embodiment of a drain mounting apparatus according to the present invention. As shown in FIG. 2, a mounting opening d is opened in a plate D called a deck plate formed in a trapezoidal waveform, and the apparatus is mounted on the upper surface side.

The support plate 10 rests on the plate D. The support plate 10 has an annular portion 11 having substantially the same diameter as the mounting port d (strictly, the inner diameter is the same), and has a length corresponding to two or three waveforms so as to be stably mounted on the waveform of the plate D. Having. The annular portion 11 is at least one above and below the plate surface.
It is necessary to have an annular frame shape protruding in the direction. The illustrated annular portion may be a short cylinder or annulus into the opening 12 in the center of the plate.
However, it is of course also possible to use one formed simultaneously with the opening 12 by press molding or the like.

The drain 40 is located at a predetermined height above the plate D.
The tubular member 20 is attached to the support plate 10 with a stopper 21 in order to support the support member 10. In order to prevent the cement mortar from leaking from the mounting opening d of the plate D, the lower end portion 22 of the tubular member 20 is fitted into the mounting opening d and closed. Therefore, there may be a gap between the lower end portion 22 and the mounting opening d to such an extent that the mortar stops. Tubular member 20 at the upper end 2 abuts the lower end 22 to the drain downward
Up to three dimensions, that is, heights can be arbitrarily set.

Since the tubular member 20 can be made of an easily processed pipe such as a vinyl chloride pipe, a pipe cut according to the thickness of the concrete surface to be cast on the plate can be used. Be free. The stopper 21 may be a bolt or a screw.
The cylindrical member 20 is screwed into the screw holes 13 to tighten the cylindrical member 20 from the outside in the radial direction.

A connecting means 30 is used for connecting the drain 40 to the tubular member 20. This coupling means 30
Is a lower locking tool 31 formed at the end with a stepped portion 34 which is locked to the lower end 22 of the tubular member 20, and an end 35 at the upper side of the drain.
, And an upper locking tool 32 and a connecting tool 33 thereof. Each of the upper and lower locking members 31 and 32 may have a three-pronged shape.
And a small hole 37 is formed in the upper part. Note that the end of the lower locking member 31 hardly comes out of the cylindrical member 20.

Reference numeral 38 denotes a wing nut, which is screwed into the external thread 39 of the coupling tool 33. The coupling member 33 has a length corresponding to the length (height) of the tubular member 20. Also 41
Is a drain port provided in the center of the drain, 42 is a pipe connected thereto, 43 is an anchor bolt attached to the drain 40, 44 is a strainer, and 45 is a ridge on the outer periphery of the drain port.

In order to mount the drain 40, the tubular member 20 cut into a predetermined length is inserted into the annular portion 11 of the support plate 10, and the lower end 22 of the cylindrical member 20 fits into the mounting opening d. Is fixed to the support plate 10 by the stopper 21. This operation may be performed on the plate D, but need not be, and may be performed in another place.

[0013] Then fitted to the upper end 23 of the tubular member 20 in the ridges 45 on the outside of the drainage port 41 by placing the drain 40, the lower end 22 of the cylindrical member 20 both ends of the lower fastener 31
And the upper locking tool 32 is attached to the upper part of the connecting tool 33 and locked on the upper side of the drain 40 to be fixed, and the drain 40, the tubular member 20 and the support plate 10 are integrally connected. State.

The above operation can be performed on the plate D,
It is performed in a completely different place, that is, the support plate 10 and the cylindrical member 2
It is also possible to assemble the 0 and the drain 40 integrally with each other in advance by the coupling means 30, and then install the assembly on the plate D later.

The lower end 22 of the cylindrical member 20 is attached to the mounting port d.
Concrete C is poured onto the plate D in a state where it is fitted to the plate D, the upper surface thereof is aligned with the upper surface of the drain, the concrete is cured, and then the coupling means 30 is removed. The removal is easy because the upper and lower locking tools 31, 2 and the connecting tool 33 can be separated by removing the nut 38.

[0016]

The apparatus according to the present invention comprises a lower locking member 3 of the coupling means 30.
1 is engaged with the lower end portion 22 of the tubular member 20, and the tubular member 20 and the drain 40 are integrated, so that the entire apparatus is assembled in another place, and then transported onto the plate D and to the mounting port d. The workability is very good because it is sufficient to put on the plate so as to fit. In addition, the height of the drain 40 can be easily adjusted by the length of the tubular member 20, so that the apparatus can perform all operations very easily by one person.

[0017]

According to the present invention, the cylindrical member 20 is fixed to the support plate 10 by the stopper 21 and the drain 40 is fixed to the cylindrical member 20 by the coupling means 30. The positional relationship between the components is naturally determined, and the components can be easily attached in a step-by-step operation, so that no skill is required.
0 makes it possible to assemble them together in advance, so that the procedures for adjustment, handling and installation are completely renewed, making it very easy. By replacing the tubular member 20, the thickness of the slab can be reduced. This type of device has an epoch-making effect in combination with being easily adaptable and being able to perform all operations only from the plate.
