Description

[Detailed Description of the Invention] [Technical Field] This invention relates to a ceiling base panel mounting structure used in buildings such as residences.

[Background technology]

Conventionally, as shown in FIG. 5, as a ceiling base panel mounting structure for attaching a ceiling base panel to a lattice beam, a hanging tree support 5 is installed horizontally between the lower chord members 2 of a pair of lattice beams. A hanging tree 6 was attached with a fixing tool 8, and a ceiling base panel 7 was attached to the hanging tree 6 with a fixing tool 8.

However, this structure requires a large number of parts,
The amount of time and effort required for construction was also inefficient. Therefore, in order to solve this problem, a panel fixture 4 as shown in FIG. 3 was proposed. This panel fixture 4 is attached to the flange 2 of the lower chord member 2 of the lattice beam.
an inner vertical plate portion 4a having an engaging convex portion 4d that engages with the inner surface of the flange 2a; and an outer vertical plate portion 4b extending from the inner vertical plate portion 4a and pressed against the outer surface of the flange 2a.
and a panel mounting piece portion 4c bent and extending from the outer vertical plate portion 4b. To install the panel fixture 4, the inner vertical plate portion 4a and the outer vertical plate portion 4b, which are integrally molded, are press-fitted and fixed to the flange 2a of the lower chord member 2, and the panel fixture 4 is
This is completed by fixing the ceiling base panel 3 to the panel mounting piece 4c.

However, in this structure, the work effort is saved as the number of parts is reduced, and the installation of the panel fixture 4 is also easier, but the ceiling base panel 3
When attaching a ceiling finishing material (not shown) such as gypsum board to the panel, there was a problem in that the panel fixture 4 would come off due to impact from below, such as when nailing.

[Purpose of invention]

The object of this invention is to provide a ceiling base panel mounting structure that allows the ceiling base panel and ceiling finishing material to be easily and reliably fixed.

[Disclosure of invention]

The ceiling base panel mounting structure of this invention consists of a lattice beam having a bottom chord member with an engaged groove formed on the outer surface of the flange by joining a pair of channel members back to back in the upper and lower sides, and a lattice beam that is in contact with the inner surface of the flange. an inner vertical plate portion; an outer vertical plate portion provided with a cut and raised piece extending from the inner vertical plate portion, abutting the outer surface of the flange, and engaging upwardly in the engaged groove;
The present invention is provided with a panel fixture consisting of a panel mounting piece bent and extending from the outer vertical plate, and a ceiling base panel fixed to the panel mounting piece.

According to the configuration of this invention, the panel fixture can be fixed by fitting the integrally molded inner and outer vertical plate portions of the panel fixture to the flanges of the bottom chord of the lattice beam. It can be done easily and reliably. In addition, an upwardly cut and raised piece is provided on the outer vertical plate part, and this cut and raised piece is engaged with the engaged groove formed on the outer surface of the flange of the lower chord of the lattice beam, so that it can be attached to the ceiling base panel. When installing a ceiling base material, even if an impact is applied from below, such as nailing, the upward cut-and-raised piece resists the impact and the panel fixture does not come off.

Embodiment An embodiment of this invention will be described based on FIGS. 1 and 2. This ceiling base panel mounting structure includes a lattice beam having a lower chord member 2 in which an engaged groove 2b is formed on the outer surface of the flange 2a by joining a pair of groove members back to back vertically;
an outer side provided with an inner vertical plate part 1a that contacts the inner surface of the inner vertical plate part 1a, and a cut and raised piece 1e that extends from the inner vertical plate part 1a, contacts the outer surface of the flange 2a, and engages upwardly in the engaged groove 2b; The panel mounting device 1 includes a vertical plate portion 1b, a panel mounting piece portion 1c bent and extending from the outer vertical plate portion 1b, and a ceiling base panel 3 fixed to the panel mounting piece portion 1c. It is something.

The panel fixture 1 is formed by bending a steel plate. The inner vertical plate portion 1a has a flange 2a of the lower chord member 2 by bending.
An engaging convex portion 1d that engages with the flange 2a is provided and is in pressure contact with the flange 2a. The outer vertical plate portion 1b has an upwardly cut and raised piece 1e so as to be able to engage with the engaged groove 2b formed on the outer surface of the flange 2a of the lower chord member 2.
is provided. The panel attachment piece 1c is provided with a plurality of fastener insertion holes 1f through which fasteners (not shown) such as nails for attaching the ceiling base panel 3 can be inserted.

The lower chord member 2 forms a part of the lattice beam,
It is formed by joining a pair of channel members vertically back to back. An engaged groove 2b is formed on the outer surface of the flange 2a of the lower chord member 2 by joining a pair of groove members.

The ceiling base panel 3 is formed by assembling wood or the like in a lattice shape, and a ceiling base material (not shown) such as gypsum board is attached as necessary.

A method for attaching the ceiling base panel 3 and ceiling finishing material according to this embodiment will be explained. With the cut-and-raised piece 1e provided on the outer vertical plate part 1b of the panel fixture 1 raised, insert the integrally molded inner and outer vertical plate parts 1a and 1b into the flange 2a of the lower chord member 2 with a hammer. etc. to make it fit. Cut-and-raised piece 1
e is positioned in advance so that it engages with the engaged groove 2b on the outer surface of the flange 2a when fitted. After the panel mounting tool 1 is fixed to the flange 2a of the lower chord member 2, the ceiling base panel 3 is fixed to the panel mounting piece part 1c with a fixing tool. Ceiling base panel 3
Once it is fixed, attach the ceiling finishing material from below with nails, etc. Installation is now complete.

According to this configuration, the panel fixture 1 can be fixed simply by fitting the integrally formed inner and outer vertical plate portions 1a and 1b of the panel fixture 1 to the flange 2a of the lower chord member 2 of the lattice beam. The attachment 1 can be easily and reliably attached. Further, an upwardly cut and raised piece 1e is provided on the outer vertical plate portion 1b, and this cut and raised piece 1e is engaged with an engaged groove 2b formed on the outer surface of the flange 2a of the lower chord member 2 of the lattice beam. Therefore, when attaching the ceiling base material to the ceiling base panel 3, even if it receives an impact from below such as nailing, the upward cut and raised piece 1e will resist the impact and the panel mount 1 will come off. Never.

In addition, in the above embodiment, the panel mounting tool 1
An engaging convex portion 1d provided on the inner vertical plate portion 1a of
was provided by bending a part of the inner vertical plate part 1a, but before the bending process, a steel material was attached to the inner vertical plate part 1a by welding to form an engaging protrusion. A portion 1d may also be formed. In addition, without providing the engaging convex portion 1d, the cross-sectional shape of the inner vertical plate portion 1a is made approximately semi-elliptic, and an opening is provided at the tip thereof, and the flange 2 is opened from the opening.
a, and press the flange 2a with elastic force to fix the panel fixture 1.

[Effect of idea]

According to this devised ceiling base panel mounting structure,
The panel fixture can be fixed by fitting the integrally molded inner and outer vertical plates of the panel fixture to the flanges of the bottom chord of the lattice beam.
Panel fixtures can be installed easily and reliably. In addition, an upwardly cut and raised piece is provided on the outer vertical plate part, and this cut and raised piece is engaged with the engaged groove formed on the outer surface of the flange of the lower chord of the lattice beam.
When installing a ceiling base material to a ceiling base panel, even if it receives an impact from below, such as nailing, the upward cut-and-raised piece will resist the impact and the panel fixture will not come off. There is.
