[Detailed Description of the Invention] (Industrial field of application) The present invention relates to a ceiling support for fixing a ceiling frame and a ceiling frame to a side wall of a building.

(Prior art and its problems) Conventionally, when attaching a ceiling to a building, the end portion of the field rim receiver is fixed to a ceiling support fixed to the side wall of the building with nails or the like, and the field rim is fixed to the field edge receiver. Although the ceiling board is attached via the above, when a relatively weak material such as gypsum board is used for the building side wall, the weight of the penetration hole such as a nail on the building side wall is loaded on the nail. There is a risk that the ceiling board may not be supported due to insufficient fixing of the ceiling support tool.

(Object of the Invention) In view of the above-mentioned conventional problems, the present invention provides a ceiling support that can be firmly attached to a building side wall even when a material having relatively low strength is used as the building side wall. The purpose is to do.

(Means for Solving Problems) In order to solve the above conventional problems, the present invention provides that the back surface side of the long plate-shaped support body 2 is an adhesive surface 3 adhered to the building side wall 12. On the adhesive surface 3, a plurality of small recessed lines 4 extending in the longitudinal direction are engraved in parallel at predetermined intervals in the vertical direction, and on the surface side thereof, a pair of upper and lower engaging projections 6 for the field receiver 13 are formed. 6 is provided in a protruding manner, and at a lower end of the support body 2, a substantially L shape for forming a joint concave portion 7 below the support body 2.
The character-shaped step portion 8 is continuously provided toward the front side, the ceiling plate receiving piece 9 is projectingly provided at the lower edge of the step portion 8, and both the upper and lower projecting portions 16 and 16 provided at the end portion of the field edge receiving portion 13. , 28, 28 are engaged with the pair of upper and lower engaging projections 6, 6.

(Embodiment) FIGS. 1 and 2 show a ceiling support 1 as an embodiment of the present invention.
And the rear surface side of the long plate-shaped support body 2 is an adhesive surface 3 to be adhered to the building side wall 12, and the adhesive surface 3 has a plurality of dovetail grooves. -Shaped small concave lines 4 are engraved in parallel lines, and crossing which forms engagement grooves 5 and 5 for engagement with the support body 2 in the vicinity of the upper edge and the lower edge of the surface side thereof. L-shaped engagement protrusion 6,
6 is projectingly provided, horizontally protrudes from the lower end of the support body 2 to the front side, and is bent downward at a right angle to form a joint concave portion 7 below the support body 2. Since the substantially L-shaped step portions 8 are connected to each other and extend horizontally from the lower edge of the step portion 8 to the front side, the ceiling plate receiving piece 9 whose tip portion is slightly bent upward is provided so as to project. is there.

As an example of specific dimensions, the height H of the ceiling support 1 is 43
mm, the width L is 16.5 mm, and the thickness R of the support body 2 is 1.8 m
m, the width h of the small groove 4 is 3 mm, the depth r thereof is 0.8 mm, the depth S of the engaging groove 5 is 1.5 mm, the width T thereof is 1.3 ± 0.2 mm, and the width l of the ceiling plate receiving piece 9 is 12.2. mm.

A ceiling mounting procedure using the ceiling support 1 will be described with reference to FIGS. First, the adhesive surface 3 of the ceiling support 1
Adhesive 11 is applied to and the adhesive surface 3 is adhered to a predetermined position on the side wall 12 of the building. In this case, even when relatively weak materials such as the building side wall 12 and gypsum board are used,
Since only the ceiling support 1 is bonded to it, the building side wall 12 is not damaged by the mounting of the ceiling support 1, and the ceiling support 1 can be firmly bonded. Further, since the adhesive 11 enters into each small groove 4 of the adhesive surface 3, the ceiling support 1 can be more firmly adhered to the building side wall 12.

Next, the bent end 15a of the plate-like connecting metal fitting 15 with the bolt and nut 14 fastened to the end of the rim receiver 13 is bent at a right angle.
After being inserted between the engaging projections 6 and 6 in a state of being slightly inclined, it is made to stand upright, and as shown by the phantom line in FIG. It fits in the engagement grooves 5 and 5. As a result, the field receiver 13 is in a state where the ceiling support 1 is fixed.

Then, the lower end of the hanging metal fitting 20 whose upper end is fastened to the insert nut 18 of the ceiling slab 17 by the bolt 19 and the above-mentioned rim receiver.
Fasten 13 and 13 with bolts and nuts 21 to hold the field receiver 13 in a horizontal state.

After that, clip 22 at the joint-corresponding position on the bottom surface of the field rim receiver 13.
The ceiling is completed by attaching the field edge 23 via the and then attaching the ceiling panel 24 between the ceiling panel receiving piece 9 of the ceiling support 1 and the field edge 23 and between the field edges 23, 23.

The field rim receiver 13 and the hanging metal fitting 20 are made of the same shape member having a substantially U-shaped cross section, and the cost of the parts is reduced by sharing the parts. Also, the ambition
A large number of mounting holes 26 are provided in two rows at predetermined intervals in the longitudinal direction of the hanging metal fitting 13 and the hanging metal fitting 20, and each mounting hole 26 has a circular hole 26a and a long hole which are alternately arranged. The round holes 26a in each row are arranged so as to face the center of the long holes 26b in the adjacent row.

When fixing the field rim receiver 13 and the hanging metal fitting 20 to the bolts and nuts 21, both are relatively moved up and down, left and right, and the bolts are inserted into the overlapped round hole 26a and the elongated hole 26b. Fix it. In this case, since a large number of combinations of the superposed states of the round holes 26a and the long holes 26b can be made, the positional relationship between the two can be finely adjusted.

The long hole 26b provides flexibility in position adjustment, and the round hole 26a prevents displacement of the bolts and nuts inserted therein. Therefore, the above-described vertical and horizontal position adjustment can be easily performed. Since the field receiver 13 and the hanging metal fitting 20 can be securely fixed, and the mounting holes 26 are formed in two rows, the position can be adjusted more finely.

In the above-described embodiment, the width T of both the engaging grooves 5 of the ceiling support 1 is reduced and the tip bent portion 15a of the connecting fitting 15 is fitted thereinto. However, in addition to this, for example, as shown in FIG. 7th
As shown in the figure, the width T of both engagement grooves 5 is increased, and the wide vertical protrusions 28, 28 of the tip ends of the connecting fittings 15 are not bent in the engagement grooves 5 without bending the tip end portions thereof. You may make it insert.

(Effect of the Invention) According to the present invention, the support tool body 2 is formed in the shape of a long plate, and the back surface side thereof is the adhesive surface 3, and the entire back surface of the support tool body 2 is made of an adhesive to the building side wall. Since it adheres to 12, not to mention the case where the building side wall 12 is made of a strong material such as wood or concrete,
Even when the building side wall 12 is formed of a material having relatively low strength such as gypsum board, the support body 2 can be firmly bonded to the building side wall 12 without damaging the building side wall 12.

Further, since a plurality of small concave lines 4 are engraved on the adhesive surface 3 of the support body 2, the adhesive enters the small concave lines 4,
The support body 2 can be more firmly adhered to the building side wall 12.

Further, since the small groove 4 extends in the longitudinal direction of the support body 2, the support body 2, the engaging projections 6, 6, the step portion 8 and the ceiling plate receiving piece 9 are extruded by, for example, an extrusion molding method. The small groove 4 can be engraved at the same time when integrally molded with a mold material, and can be mass-produced at low cost.

Furthermore, both upper and lower protrusions 16, 1 provided at the end of the field receiver 13
By simply engaging 6, 28, 28 with the pair of upper and lower engaging projections 6, 6 of the support body 2, the field receiver 13 can be easily and surely connected to the support body 2.
