Description

[Detailed description of the invention] [Technical field] This invention relates to a horigotatsu whose main body is installed under the floor.

[Background technology]

Traditionally, horigotatsu, which are installed under the floor and have a heater box installed at the bottom, have been widely used.

In such a horigotatsu, as shown in FIG. 3, reinforcing rods 14 are provided along the width direction on the outer surface of the bottom plate 12 in order to prevent the bottom plate 12 of the main body 11 installed under the floor from being pushed through and to prevent it from bending. has been done.

As shown in FIG. 4, this reinforcing rod 14 has rising pieces 14a at both ends, and a punch-in prevention portion 14c that holds the bottom plate 12 along the width direction of the bottom plate 12.
and a deflection preventing part 14b extending downward from the punching preventing part 14c and protruding parallel to each other, and the rising pieces 14a are formed into a groove shape, and bolts 15 and nuts 16 are attached to the outer surfaces of the peripheral walls 13, 13 facing each other. It is fixed with the fixing device.

However, as shown in FIG.
In order to install the reinforcing rung 14 protruding from the bottom surface, an extra depth under the floor is required by the protrusion length A, and in places where the depth under the floor is not sufficient, the protrusion length A of the reinforcing rung 14 is required. It got in the way and made the work complicated.

[Purpose of invention]

The purpose of this invention is to provide a hori kotatsu which can prevent the bottom plate from being pushed through and from bending without requiring an extra depth under the floor.

[Disclosure of invention]

The Horigotatsu of this invention consists of a main body installed under the floor, a reinforcing deflection prevention beam that also serves as a slat support, and is installed on the inner surface of the bottom plate of the main body and between the inner surfaces of the opposing peripheral walls. It is provided with a flat plate-like punch-out prevention plate having rising pieces at both ends thereof, which are arranged on the outer surface of the bottom plate corresponding to the mounting position of the deflection prevention beam and fixed to the outer surface of the opposing circumferential wall of the main body.

In this way, according to this invention, the reinforcing and anti-deflection slats that also serve as slatted slats are installed on the inner surface of the bottom plate of the main body, which not only prevents the bottom plate from sagging, but also includes the slats on the bottom surface of the bottom plate. There is no need to take extra depth under the floor for installation as there is no protrusion. In addition, this deflection prevention beam can also be used as a support for slats, eliminating the need for special members for installing the slats.

In addition, since a flat plate-shaped punch-through prevention plate is installed on the outer surface of the bottom plate corresponding to the mounting position of the deflection prevention beam, punch-through of the bottom plate can be reliably prevented without taking up extra space on the bottom surface of the bottom plate.

An embodiment of the present invention will be described with reference to Fig. 1 and Fig. 2. That is, as shown in Fig. 1, the sunken kotatsu is composed of a main body 1 installed under the floor,
A peripheral wall 5 is disposed on the inner surface of the bottom plate 2 of the main body 1 and faces the bottom plate 2.
The deflection prevention rungs 3 are installed between the inner surfaces of the bottom plate 2 and the perimeter walls 5 and 5 of the main body 1. The deflection prevention rungs 3 are installed on the outer surface of the bottom plate 2 at the positions corresponding to the positions of the deflection prevention rungs 3.
and a flat puncture prevention plate 4 having raised pieces 4a at both ends fixed to the outer surface of the floor board 5.

As shown in FIG. 2, the deflection prevention lever 3 is fixed to the inner surface of the bottom plate 2 of the main body 1 from the outer surface of the bottom plate 2 with screws 6 or the like.

Further, as shown in FIG. 2, the punch-through prevention plate 4 is formed of a thin metal plate, etc., and the punch-through prevention plate 4 is inserted into the blind nut 7 buried in the hole in the peripheral wall 5. It is fixed to the main body 1 by inserting a bolt 8 into the hole provided at the end of the rising piece 4a and screwing the groove of the bolt 8 into the groove of the blind nut 7.

When installing the main body 1 under the floor, a deflection prevention lever 3 is fixed in advance to the inner surface of the bottom plate 2, and then a punch prevention plate 4 is fixed to the outer surface of the bottom plate 2, and then the main body 1 is installed under the floor.

In this way, since the deflection-preventing step 3 and the stepping-through preventing plate 4 do not protrude from the lower surface of the bottom plate 2, the bottom plate 2 can be prevented from bending or stepping through without requiring extra depth under the floor. In addition, since the punch-through prevention plate 4 is arranged at a position corresponding to the mounting position of the deflection-prevention lever 3 through the bottom plate 2 of the main body 1, its strength is increased, and the bottom plate 2 can be reliably prevented from punching through and bending. I can do it.

Incidentally, the deflection-preventing step 3 can also be used as a slat receiving step for holding a slat on its upper surface, and also serves as a positioning member for a heater box installed at the bottom of the main body 1.

[Effect of idea]

According to the Horigotatsu of this invention, a reinforcing and anti-deflection slat that also serves as a slat support is installed on the inner surface of the bottom plate of the main body, which not only prevents the bottom plate from sagging, but also has a slat on the underside of the bottom plate. There is no need to take extra depth under the floor for installation as there is no protrusion.
In addition, this deflection prevention beam can also be used as a support for slats, eliminating the need for special members for installing the slats.

In addition, since a flat plate-shaped punch-through prevention plate is installed on the outer surface of the bottom plate corresponding to the mounting position of the deflection prevention beam, punch-through of the bottom plate can be reliably prevented without taking up extra space on the bottom surface of the bottom plate.
