Description

[Detailed description of the invention] This invention relates to a connecting metal fitting for connecting the roof panel that forms the floor of the upper floor to the roof edge that serves as the base of the ceiling of the lower floor. To reliably connect a ceiling edge for a downstairs ceiling base to a floor panel whose edge is a groove-shaped material used for an upstairs floor, which can be easily formed without loss and with a small number of processing steps.

Conventionally, in order to connect a ceiling edge for a downstairs ceiling base to an upstairs floor panel, a connecting tool 1 as shown in FIG. Insert one of the pieces 2, 2 through the joint between a pair of adjacent panels 3°3 as shown in FIG. As shown in FIG.
The roof edge 7 is suspended and supported from the panel 3 by driving nails into it, but this connector 1 needs to be bent into a complicated shape, and its development is shown in Figure 4. As shown, there was a problem in that the cutting loss was large.

The present invention has been devised in view of the above points, and will be described in detail below based on the embodiments shown in the figures.

The floor panel 10 that forms the upper floor is constructed by a channel member 12 made of steel and having a U-shaped cross section fixed to the lower end of the surface member 11 with an upper horizontal piece 13 with its opening opened outward. The pair of floor panels 10 are connected with the upper horizontal piece 13 and the lower horizontal piece 14 of the channel member 12 facing each other.

As shown in FIG. 5, the connector 15 is formed by drilling a hole in a single rectangular metal plate, and has an opening at one end of the rectangular metal plate at one end in the longitudinal direction. The other end is divided into an upper piece 17 and a lower piece 18 by a slit 16 that reaches approximately the middle in the width direction of the metal plate, and the upper piece 17 is folded at right angles to the lower piece 18 on a line including this slit 16. It is curved.

Further, elongated holes 19 and 20 are bored in the width direction of the lower piece 18, and the lower piece 18 is divided into a main piece 21 and a stone piece 22. A nail hole 23 is bored in each of the pieces 22, and a through hole 24 is bored in the main piece 21, into which a rod-shaped jig called a shino is inserted.

As shown in FIG.
Insert the upper piece 17 through the joint 30 formed between the two lower horizontal pieces 14, hook the upper piece 17 onto the upper surface of one of the lower horizontal pieces 14, and then insert the lower side of the groove-shaped member 12 as shown in FIGS. 7a and 7b. A jig 31 is inserted into the through hole 24 of the lower piece 18 protruding from the top, and the jig 31 is turned to bend the main piece 21 at a substantially right angle to the stone piece 22 through the elongated holes 19 and 20 arranged vertically. The main piece 21 and the stone piece 22 are made to face the outer surface of the edge 25 used as a ceiling base on the lower surface of the floor panel 10, respectively, and nail holes 2 are provided in both the left and right pieces 21 and 22.
3, nails 26 are driven into the field edge 25 to suspend and fix the field edge 25 to the floor panel 10.

The main piece 21 can be used even if it is bent in either direction as shown in FIGS. 8a and 8b.

As described above, the present invention uses bent rectangular metal plates as connection plates, so there is less board loss and the connection strength between the floor panel and the roof edge is high.

Here, if the width of the slit 16 is set slightly narrower than the width of the lower horizontal piece 14, when the connecting tool 15 is hooked on the groove-shaped member 12, the edge of the lower horizontal piece 14 will bite into the slit 16, and the connecting tool 15 will be cut into the slit 16. is securely fixed to the groove-shaped member 12.

The connector 35 shown in FIG. 9 is formed by bending a rectangular metal plate into an L-shape and cutting out the lower part of one side piece 36. A notch 39 is provided in the upper part of the notch 38, and A nail hole 40 is provided in the lower part of the lower and other side pieces 37.

This connector 35 has a notch 39 inserted into the lower horizontal piece 14 of one of the groove-shaped members 12 as shown in FIG. A nail 26 is driven into one side wall from below the notch 39, and the lower part of the other side piece 37 is fixed to the side surface of the field edge 25 with the nail 26.

In the figure, 28 is a ceiling plate.
