DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will now be described in detail with reference to the accompanying drawings. FIG. 1 shows a rear surface exploded perspective view of an air conditioning floor panel base 6 according to the present invention. The air-conditioning floor panel base 6 includes a top plate member 2 made of a steel plate, and a rectangular frame-shaped base frame member 4 joined to the back surfaces of the four sides of the top plate member 2.
And a reinforcing member 5 for reinforcing the top plate member 2 from the back surface.

The top plate member 2 in this embodiment is provided with four blower openings 1 at the corners thereof, and positioning bosses 11 are projected at appropriate positions. Further, holes 13 through which leg holders 12 to be described later are inserted are formed at four corners of the top plate member 2. When a damping steel plate is used as the top plate member 2, it is possible to reduce vibration of the fan unit 7 described later or walking noise.

The underframe member 4 is formed by swelling the bulging portions 14 continuous on four sides by drawing a steel plate, and the leg holders 12 mounted on the corner portions of the bulging portions 14 (see FIG. 2). 3), the supporting leg 3 is held so that the protruding height can be adjusted. This underframe member 4 is joined to the back surface of the top plate member 4 by spot welding, for example, and the joining position is regulated by fitting a boss 11 on the top plate member 2 side into a positioning hole (not shown). Further, the bulging portion 14 of the underframe member 4 has screw holes 15 and 1 for fixing a fan unit 7 described later.
5 are provided at a predetermined pitch.

On the other hand, the reinforcing member 5 is composed of a reinforcing beam member 5A having a longitudinal dimension slightly shorter than the distance between the inner and outer peripheral edges of the underframe member 4, and an auxiliary reinforcing member 5B. The reinforcing beam member 5A is a member having a hat-shaped cross section having a widthwise dimension that does not block the blower opening 1 when joined to the ceiling plate, and spot welding the reinforcing beads 16 provided on the ceiling wall to the ceiling plate. It is fixed to the center of the back surface of the member 2. In FIG. 1, reference numeral 17 denotes a positioning hole into which the boss 11 of the top plate member 2 fits for positioning with the top plate member 2.

Further, the auxiliary reinforcing member 5B is a member having an area capable of filling the space between the ventilation openings 1 of the top plate member 2, and prevents the interference with the ventilation opening 1 at the opposite side edges. An arc-shaped notch 18 for cutting is provided. Further, the auxiliary reinforcing member 5B is bent a plurality of times in parallel with the forming edge of the notch 18 for reinforcement, and is positioned by fitting the positioning hole 19 to the boss 11 and then spotted on the back surface of the top plate member 2. To be joined.

FIG. 2 shows the arrangement of the reinforcing member 5. In this embodiment, the top plate member 2 is reinforced by one reinforcing beam member 5A and two auxiliary reinforcing members 5B and 5B. The reinforcing beam member 5A is arranged so as to cross the center of the top plate member 2. The auxiliary reinforcing member 5B is arranged at the exposed portion of the remaining top plate member 2. In this state, three sides of the ventilation opening 1 of the top plate member 2 which is weak in strength are reinforced by the underframe member 4 and the reinforcing beam member 5A, and the remaining portions are reinforced by the auxiliary reinforcing member 5B. The deformation of the top plate member 2 from the periphery of the ventilation opening 1 is prevented.

On the back surface of the air-conditioning floor panel base 6 formed as described above, as shown by a chain line in FIG. 2, a ventilation grill 20 and a fan unit 7 are mounted. As shown in FIGS. 3 and 4, the fan unit 7 includes a box-shaped casing 8 opened upward,
The erection beam 9 erected between the upper edges of the casing 8.
And a fan main body 10 suspended from the erection beam 9. The fan main body 10 allows a bell mouth 21 fixed to the bottom wall to be opened from an opening (not shown) formed in the center of the bottom wall of the casing 8. It is configured to blow cool air to the side of the ventilation grille 20 through. Further, a sound absorbing material 22 such as glass wool is fixed to the bottom wall of the casing 8 to prevent generation of wind noise.

Further, the erection beam 9 of the fan unit 7
Is formed to have substantially the same size as the groove width of the reinforcing beam member 5A on the base 6 side, and a screw insertion hole 24 is formed in the flange portion 23 in which the upper end edge of the casing 8 is folded outward. In FIG. 3, reference numeral 25 indicates a lead wire for supplying power to the fan body 21.

However, the fan unit 7 is positioned by fitting the erection beam 9 to the reinforcing beam member 5A on the side of the base 6 and then positioning the base by the screw 26 that is inserted through the screw insertion hole 24 of the flange portion 23. It is fixed to the back surface of the base 6 by being screwed into a screw hole 15 provided in the bulge 14 of the base 6.

FIG. 5 shows another embodiment of the floor panel base 6 for air conditioning. In the description of this embodiment, the same components as those in the above-described embodiment are designated by the same reference numerals in the drawings, and the description will be omitted. This embodiment corresponds to an air-conditioning floor panel in which one blower opening 1 is opened, and each component of the underframe member 4, the reinforcing beam member 5A, and the auxiliary reinforcing member 5B is the same as the above-described embodiment. The same is used. Further, the top plate member 2 is provided with one large blower opening 1 at the corner according to the specifications of the air conditioning floor panel, and the configuration other than the blower opening 1 is exactly the same as the above-described embodiment. Has been done.

Further, in this embodiment, the reinforcing beam member 5A is fixed close to the peripheral edge of the air blowing opening 1, and one auxiliary reinforcing member 5B is joined to the remaining portion, and the air blowing opening is formed. A grill mounting member 27 is joined to the peripheral edge of 1.

In this embodiment, the grill mounting member 27
Is formed so that it can also serve as a reinforcing material for the peripheral edge of the blower opening 1. As shown in FIG. 6, the top plate joining piece 28 provided on two adjacent sides and the peripheral edge of the blower opening 1 are reinforced. And a top plate joining piece 28.
Then, the opening reinforcing piece 29 is spot-welded and joined to the back surface of the top plate member 2.

[0022]

As is apparent from the above description, according to the floor panel base for air conditioning of the present invention, it is possible to manufacture products of various specifications by simply selecting the top plate member appropriately. Can be shared, and the manufacturing cost can be reduced.

According to the air conditioning floor panel of the present invention, the erected beam of the fan unit is fitted to the back surface of the reinforcing beam member when the fan unit is fixed,
And, since the casing is fixed to the underframe member, including the floor panel base for air conditioning, the overall strength can be improved, and by fixing the upper end of the casing to the back surface of the underframe member, A well-sealed wind tunnel is formed on the back surface of the base, which makes it possible to effectively prevent the generation of wind noise, and the screws for fixing the fan unit are exposed on the surface of the base. Since it does not, it is possible to enhance the aesthetics. Furthermore, a reinforcing beam with a hat-shaped cross section
To fit the erection beam in the groove of the member,
The thickness can be reduced and it can be used for double floors with a low floor space.
Can respond.
