Description

[Detailed explanation of the idea] For example, when installing a forced air supply/exhaust type combustion equipment such as a gas hot air heater that supplies combustion air from outside and exhausts exhaust gas outdoors to a wall, it is necessary to supply air to the equipment itself. , exhaust pipes, fuel gas supply pipes, etc. are connected, so for safety reasons, it is necessary to securely attach the main body of the device so that it does not move easily.

However, in the past, one end of the L-shaped fixture connected to the device body was screwed directly to the wall surface, so the load of the device body was concentrated on this threaded part, and the material of the wall was affected. In some cases, the installation has a great effect on the strength, and it is especially difficult to install it on earthen walls or concrete walls.

This invention is based on this type of forced air supply/exhaust combustion equipment.
Balanced air supply/exhaust top that can be installed through the wall.
Alternatively, the wall penetrating sleeve used to attach the air supply/exhaust top has a flange at one end that faces the inside of the wall, a male thread on the outer peripheral surface of the other end, and is inserted into a through hole in the wall. We focused on the fact that a nut is screwed into the male threaded part protruding from the through hole, and it is tightened from both the inside and outside of the wall, so it can be installed very firmly regardless of the material of the wall. The purpose was to create a forced air supply/exhaust type combustion equipment for walls that is safe and easy to install, and that can be installed sufficiently firmly without being greatly affected by the material of the wall. Installation is at the point of providing structure.

An embodiment of the present invention will be described based on the drawings. When a forced air supply/exhaust type combustion equipment body B is attached to the inner surface of a wall A, one of the fixing fittings 1 consisting of a wall-side fixing fitting 1a and an equipment-side fixing fitting 1b is used. , the ring portion formed on the wall-side fixing fitting 1a is fitted into the wall penetrating sleeve 2 for mounting the balance type air supply/exhaust top C, and the flange 3 formed at one end of the sleeve 2 and the The ring portion is fastened to the inner surface of wall A at multiple locations in the circumferential direction with screws 4, and screws 5 are secured to one end of this wall side foot fitting 1a and the back of the device main body B. Equipment side fixing bracket 1
b and one end thereof are connected to each other by a screw 6.

In the figure, 7 is a nut screwed onto the male threaded portion 8 on the outer circumferential surface of the sleeve 2, 9 is a tapered washer, 10 is an air supply pipe, and 11
is an exhaust pipe.

FIG. 3 shows another embodiment, in which the wall-side fixture 1a is engaged with a part of the upper half of the flange 3 of the sleeve 2, and a screw 4 passing through both 1a and 3 is attached to the inner surface of the wall A. The feature is that they are fastened together, and the other structures are substantially the same as the previously described embodiments, so explanations will be omitted.

4 and 5 show different embodiments, and FIG. 4 shows a state in which the wall-side fixing fitting 1a is engaged with a part of the upper half of the flange 3 of the sleeve 2, and the flange 3 is penetrated. The wall side fixture 1a is configured to be fastened between the flange 3 and the wall A by screwing in the screw 4 that connects the wall side fixture 1a to the flange. 3, and is configured to be fastened together to the inner surface of wall A with a screw 4 passing through both 1a and 3.

The other configurations are substantially the same as those of the previously described embodiments, so explanations will be omitted.

In any of the above embodiments, if necessary, the side wall fixing metal fitting 1a may be configured to have a shape such as a square ring shape or an inverted U shape that fits into the sleeve 2 in a rotationally prevented manner. You may.

Further, as shown in FIG. 6, the device-side fixing fitting 1b can also be implemented by having one end inserted and connected to the back surface of the device main body B from below (or above).

In short, the structure of mounting a forced air supply/exhaust type combustion device on a wall surface according to the present invention is as follows: The other end of the fixing bracket 1, which connects one end to the forced air supply/exhaust type combustion device main body B, is attached to the wall A.
When inserted into the through hole of the wall A, tightening is fixed on both the inner and outer surfaces of the wall A by the flange 3 formed on one end and the nut 7 screwed onto the male threaded part 8 formed on the outer peripheral surface of the other end. The air supply/exhaust top C or its installation is characterized in that the other end of the fixing fitting 1 is fastened to the inner surface of the wall A via the flange 3 of the wall penetrating sleeve 2. Since the fixture 1 is fastened to the inner surface of the wall A via the flange 3, the force in the direction of separating the device body B from the wall A surface is applied to the inner and outer surfaces of the wall A by the nut 7 and the flange 3. Supply/exhaust top C securely fastened on both sides
or will be supported by a wall-penetrating sleeve 2;
Mounting the device body B using the material of wall A has almost no negative effect on the strength, and even on earthen or concrete walls, special mounting can be done sufficiently firmly without using planks. There is an effect that can be done.

In particular, if the fixture 1 is composed of the wall-side fixture 1a and the device-side fixture 1b connected to the back of the device body B, the above-mentioned installation procedure has fewer restrictions and the workability is further improved. It's something you get.
