Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a ceiling base panel attachment tool for attaching a ceiling base panel to a beam made of shaped steel or the like.

[Background technology]

Conventionally, when attaching a ceiling base panel to a shaped steel beam, the ceiling base panel is attached via a hanging tree to a hanging tree bracket that spans between the beams, but this has the problem of requiring a large number of parts and construction man-hours. .

Therefore, we devised a ceiling base panel mount to attach the ceiling base panel directly to the beam. In this case,
Since it is time-consuming to make bolt holes etc. in the beams, we considered attaching the ceiling base panel fixtures by sandwiching the flanges of the beams.

However, there are, for example, lattice beams and floor beams to which ceiling base panels are attached, and the shapes of the parts to which ceiling base panels are attached are significantly different between these beams. That is, in the case of a lattice beam, a ceiling base panel is attached to the bottom chord, but the bottom chord has an H-shaped cross section and the flange is oriented vertically. On the other hand, the floor beams have an I-shaped cross section and the flanges are oriented horizontally.

As a result, the same ceiling base panel fixtures cannot be used for both lattice beams and floor beams, and both types of beams are often used in one building, which increases the number of types of components and makes cost estimation, component management, and construction difficult. There was a problem with poor sex etc.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a ceiling base panel mounting tool that can be easily attached to both a beam having a vertical flange and a beam having a horizontal flange, and can be used to attach a ceiling base panel.

[Disclosure of the invention]

The ceiling base panel fixture of the present invention includes: a beam-standing flange clamping part consisting of two clamping pieces folded back into an inverted U-shape; and a ceiling panel mounting part extending from the lower end of one of the clamping pieces. and a beam horizontal flange mounting part having a clip pinching margin that is bent horizontally from the lower end of the other clamping piece and extends laterally beyond the clamping piece.

According to the structure of the present invention, when installing on a beam having a vertical flange such as a lattice beam, the ceiling base panel is hooked in an inverted U-shape to the vertical flange of the beam in a clamping state. Install the fixture. Attach the ceiling base panel to the ceiling base panel mounting area using nails or other fixing devices. When installing on a beam with a horizontal flange, such as a floor beam, place the beam horizontal flange mounting part on the horizontal flange of the beam. Then, the clip pinching margin portion of the beam horizontal flange mounting portion is held in a state of being overlapped with the horizontal flange of the beam by a U-shaped clip made of a spring material or the like. In this way, it can be attached to both beams with vertical flanges and beams with horizontal flanges. Furthermore, when attaching to any beam, it can be attached by simply sandwiching the beam flanges, so there is no need for bolt hole machining or screwing work, and the installation work is simple.

Embodiment An embodiment of the present invention will be described based on FIGS. 1 to 3. Figure 1A shows the case where the ceiling base panel fixture 1 is used to attach the ceiling base panel 2 to the beam 3 that will become the floor beam, and Figure 1B shows the case where the ceiling base panel 2 is attached to the lower chord member 4a of the beam 4 that will become the lattice beam. Shows how to install.

As shown in FIG. 1, this ceiling base panel fixture 1 includes a beam-standing flange clamping part 5 consisting of two clamping pieces 5a and 5b that are folded back into an inverted U shape.
A ceiling base panel mounting portion 6 extends to the lower end of one clamping piece 5a, and a clip pinching margin is bent horizontally from the lower end of the other clamping piece 5b and extends laterally beyond the clamping pieces 5a and 5b. The beam horizontal flange mounting portion 7 has a portion 7a.

The beam standing flange holding part 5 and the beam horizontal flange mounting part 7 are formed by bending a single metal plate such as a spring material. The lower end of one of the clamping pieces 5a extends longer than the other clamping piece 5b, and a ceiling base panel mounting portion 6 is joined to the extended portion with a joining tool 8 such as a rivet. Ceiling base panel mounting part 6
is bent into an L shape and provided with a plurality of fastener insertion holes 9. As shown in FIG. 1B, the beam horizontal flange mounting portion 7 is provided with a plurality of locking protrusions 10 located at the clip pinching margin 7a.

The clip 11 is made of a leaf spring or the like that is folded back into a U-shape, and can be held in a state where the horizontal flange 3a of the beam 3 and the clip pinching margin 7a are overlapped.

In FIG. 1A, a beam 3 serving as a floor beam is made of I-section steel and has a horizontal flange 3a. The ceiling base panel 2 is constructed by assembling vertical and horizontal wooden frame members 2a and 2b in a lattice shape (see FIG. 3), and a ceiling surface material (not shown) is pasted thereon. When installing on such a beam 3, place the beam horizontal flange placement part 7 of the ceiling base panel fixture 1 on the horizontal flange 3a of the beam 3, and use the clip 11 to connect the clip pinching margin 7a and the horizontal flange 3a of the beam 3. Insert. At this time, the tip of the clip 11 is inserted into the clip pinching margin 7.
It engages with the locking protrusion 10 of a. The ceiling base panel attachment part 6 is fixed to the frame material 2a of the ceiling base panel 2 with fixing tools such as nails.

In FIG. 1B, the lower chord member 4a of the beam 4, which is a lattice beam, has an H-shaped cross section made by vertically welding channel members, and has an upright flange 4b. When installing on such a beam 4, use the ceiling base panel mount 1.
The beam upright flange holding portion 5 is engaged with the upright flange 4b in a sandwiched state. In this case, the beam standing flange clamping part 5 is rigid enough to be clamped by being driven in with a mallet or the like.

Note that the beam 3 in FIG. 1A and the beam 4 in FIG. 1B are provided in parallel in the same building as shown in FIG. 2, and are used to attach the same ceiling base panel 2. 12 is an outer wall panel.

In this way, the same ceiling base panel fixture 1 can be used to attach both the beams 3 and 4, the beam 4 having the vertical flange 4b (FIG. 1B) and the beam 3 having the horizontal flange 3a (FIG. 1A). Can be installed. Therefore, the number of types of components such as hardware is reduced, and cost estimation, construction, component management, etc. are facilitated. Furthermore, when attaching to either beam 3 or 4, it is only necessary to drive in the beam standing flange clamping part 5 or the clip 11 and clamp it, so there is no need for bolt hole drilling or screw fastening work, and the installation is easy. .

In the above embodiment, the beams 3 and 4 are floor beams or lattice beams, but they may also be roof beams, and as long as the beams have horizontal flanges or vertical flanges, they can be attached to the ceiling base. Panel mounts can be used.

〔Effect of the invention〕

When the ceiling base panel fixture of the present invention is installed on a beam having a vertical flange such as a lattice beam, the inverted U-shaped beam vertical flange clamping part is hooked onto the vertical flange of the beam in a clamping state. Install the base panel mounts. Attach the ceiling base panel to the ceiling base panel mounting area using nails or other fixing devices. When installing on a beam with a horizontal flange, such as a floor beam,
Place the beam horizontal flange mounting part on the horizontal flange of the beam. Then, the clip pinching margin portion of the beam horizontal flange mounting portion is held in a state of being overlapped with the horizontal flange of the beam by a U-shaped clip made of a spring material or the like. In this way, it can be attached to both beams with vertical flanges and beams with horizontal flanges. Also, when installing on any beam,
It can be installed by simply inserting the beam flange, so
There is no need for bolt hole machining or screw tightening work, and the installation work is simple.
