Description

[Detailed description of the invention] (Field of industrial application) The present invention has a parting edge and an adjustment bolt screwed into the parting edge, so that it can The present invention relates to a ceiling partitioning device for a building, which enables efficient formation of ceiling partitions with high precision and excellent appearance.

(Structure) The ceiling parting device 1 for a building according to the present invention (hereinafter referred to as the device) has leg pieces 7, 7 on the top and bottom of a base plate 5 that can receive a wall plate 4, the tip portions 6 of which can come into contact with the wall base surface 17. It is made of light metal and has a groove 11 recessed in the longitudinal center of the board 5, and a support piece 9 that supports the end of the ceiling plate 8 from below at the upper end of the board 5. a parting edge 2; adjustment bolts 3 screwed together at required intervals in the groove 11 portion so as to pass through the groove bottom 12 of the groove 11; Wall subsurface 1 at section 16
7, and at its base end 19 there is an engaging portion 2 that can engage with an engaging portion of a rotating tool such as a screwdriver.
0, and is characterized in that the adjustment bolt 3 is provided with a nail hole 21 that passes through it in the axial direction.

(Function) The adjusting bolt 3 is rotated as appropriate depending on the degree of unevenness of the wall base surface 17, and the parting edge 2 is adjusted so that the board surface 25 is in contact with the inner surface 27 of the wall board 4 in the required state. After adjusting the position so that they touch each other, and then fixing the adjustment bolt 3 to the wall base 17 using the nail 22 that passes through the nail hole 21 of the adjustment bolt 3,
The parting edge 2 is fixed in position to the wall base surface 17 in accordance with the tensioned state of the wall board 4. In this state, the wall base surface 17 receives the inner surface 27 of the wall board 4, and the support piece 9 supports the end portion 28 of the ceiling board 8 from below.

(Example) Examples of the present invention will be described below based on the drawings.

1-2, the device 1 of the invention comprises a parting edge 2 and an adjustment bolt 3. As shown in FIGS.

The parting edge 2 is made of a light metal such as aluminum, and has legs on the top and bottom (in this example, the top and bottom ends) of the base plate 5 that can receive the wall board 4, so that the tip part 6 can come into contact with the wall base surface. The pieces 7, 7 are bent to face each other, and a ceiling plate fitting groove 10 is continuously provided in the upper end portion of the substrate 5, the support piece 9 supporting the end portion of the ceiling plate 8 being a component. ing. Further, a groove 11 having a rectangular shape, for example, is recessed in the longitudinal center portion of the substrate 5, and protrusions 13, 13 are opposed to each other on both sides of the bottom surface 12 of the groove 11. It is provided. In the groove 11, threaded holes 15 into which the adjustment bolts 3 can be screwed are provided at required intervals over the entire width of the groove bottom 12 and the inner surfaces of both the protrusions 13, 13.

The adjustment bolt 3 can come into contact with the wall base surface 17 at its tip 16, and its base end 19
is provided with an engaging portion 20, for example, a rectangular blind hole, which can be engaged with an engaging portion of a rotary tool such as a screwdriver, and a nail hole 21 penetrating in the axial direction at the bottom of the blind hole. is drilled. In this embodiment, the length of the adjustment bolt 3 is such that the length of the fixing nail 22 is determined even when the adjustment bolt 3 is screwed into the screw hole 15 and its tip 16 is not in contact with the wall base 17. The nail head 23 is set to fit within the groove 11 (see FIG. 4).

Next, the method of forming a ceiling parting using the apparatus 1 of the present invention will be explained with reference to FIGS. 3 and 4. In order to form the ceiling parting, first, the parting edge 2 is fixed in the horizontal direction at a required height position on the wall base surface 17. At that time, the adjustment bolt 3 shall be screwed into the screw hole 15 in advance, and the parting edge 2 should be aligned with the wall base surface 17 so that the leg pieces 7, 7 face the wall base surface 17.
is applied to. In this state, the adjustment bolt 3 is rotated as appropriate depending on the degree of unevenness of the wall base surface 17, and the parting edge 2 is adjusted so that the board surface portion 25 is vertical.
After that, the adjustment bolt 3 is fixed to the wall base using the nail 22 inserted through the nail hole 21 of the adjustment bolt 3. After the parting edge 2 is fixed in this manner, the inner surface 27 of the upper end portion 26 of the wall plate 4 is brought into contact with the substrate surface portion 25, and the fitting groove 10
The end portion 28 of the ceiling board 8 is fitted into the support piece 9 to support the end portion 28, and the wall board 4 and the ceiling board 8 are
When fixed to the parting edge 2 or the ceiling base material 29, etc.,
The required ceiling parting 30 will be formed. Note that when the protrusions 13, 13 are provided at the bottom of the groove 11 as in this embodiment, even if the thickness of the groove bottom 12 is not large, the adjustment bolt 3 can be stably inserted into the screw hole. 15 can be screwed together. Furthermore, the protrusions 13, 13 also function as reinforcing ribs, making the parting edge 2 extremely stable in terms of strength.

(Effects of the invention) As a result of the device of the present invention comprising a parting edge and an adjustment bolt screwed into the parting edge, the adjustment bolt can be rotated as appropriate depending on the degree of unevenness of the ground beneath the wall. Accordingly, the position of the substrate surface portion that receives the wall board can be easily adjusted to match the state in which the wall board is installed. The facing edge receives the wall board at its base and also supports the end portion of the ceiling board by means of a support piece.

For this reason, when using the apparatus of the present invention, it is possible to efficiently form a ceiling partition with high precision and excellent appearance, regardless of whether or not the wall base surface is uneven.
