Description

[Detailed Description of the Invention] The present invention relates to a mounting structure for ceiling panels in prefabricated buildings.

When a refrigerator, refrigerator, etc. is constructed with a heat insulating panel and installed inside a building, a ceiling panel is attached as shown in FIG. 1, which is conventionally common. That is, as shown in FIGS. 1A and 1B, the reinforcing beams 2 extend along the upper and lower sides of the joint ends of the ceiling panel 1.
It is fixed with a heat-insulating penetrating bolt 3, suspended from a building frame (not shown) with a wire 5 using a reinforcing beam 2 or a bolt seat 4, and adjusted with a turnbuckle 6. installed. In such a mounting structure, a reinforcing beam 2 is required, and holes must be drilled in the reinforcing beam 2 and the ceiling panel for the through bolts 3, which deteriorates the insulation properties and makes it difficult to align the positions of these holes during assembly. It was difficult and the workability was poor. Furthermore, if the ceiling is wide, the reinforcing beams 2 must also be connected, making the work even more troublesome.

The purpose of this invention is to eliminate these conventional drawbacks,
To provide a ceiling panel mounting structure which can firmly connect ceiling panels to each other and suspend them from a building frame with a simple operation.

For this purpose, the present invention uses a clamp holder,
It is characterized in that the panels are firmly connected and held by clamping inclined brackets provided near the panel edges by the clamp holders, and the clamp holders are suspended from the frame.

Embodiments of the present invention will be described below with reference to FIGS. 2 to 5.

FIG. 2 generally shows the ceiling panel mounting structure according to the present invention. The ceiling panel 1 is provided with inclined brackets 10 near its edges, and these inclined brackets 10 are designed to hold together a clamp holder 11 which is a feature of the present invention.
That is, by this clamping, a pressing force is exerted on the ceiling panels 1 in the direction of the arrow, and both ceiling panels 1 are firmly connected and held. The ceiling panel 1 is attached by the clamp holder 11 being adjustable and suspended from a building frame (not shown) by a wire 5 via a turnbuckle 6.

The slanted bracket 10 is slanted approximately 30 degrees away from the vertical plane, as shown in FIG. 2, to prevent the clamp body 12 of the clamp holder 11 from sliding upwardly. These inclined brackets 10 are fixed by bolts 8 to nuts 7 buried in advance inside the ceiling panel 1, and a plurality of them are provided at appropriate intervals along the edge of the ceiling panel 1. . Other methods of fixing the inclined bracket 10 to the ceiling panel 1 are also possible, and it is also possible to use a ceiling panel 1' having an inclined bracket part 10' integrally formed on the panel surface plate as shown in FIG. 2a. be. In any case, in order to ensure heat insulation, the ceiling panel 1 must have a structure that does not require drilling holes through the ceiling panel 1 in the thickness direction.

As shown in FIGS. 3 to 5, the clamp holder 11 includes a pair of clamp bodies 12, a suspension part 13,
A pair of link levers 14A and 14B are pivotally connected to the suspension part 13 so that the clamp bodies 12 can swing toward and away from each other while maintaining a parallel state.
and the bolt 1 which is clamped by the clamp body 12.
5 and a nut 16.
As shown in FIG. 5, the clamp body 12 is formed by bending a metal plate such as aluminum into a U-shaped cross section, and the above-mentioned inclined brackets 10 are provided at the lower part of each side edge extending inward. A sloped edge 12A is formed that matches the slope of. The suspension part 13 is a similar metal member, and an opening 18 is formed in the upper part for hooking a hook 17 (FIG. 2) for hanging. The link levers 14A and 14B are parallel to each other and their ends are connected to the clamp body 12.
and the suspension part 13, respectively. Here, the link lever in the upper position is shown as 14A, and the link lever in the lower position is shown as 14B, but these link levers are the same part. Note that it is not always necessary to provide two link levers 14 in parallel at the same location, but at least one link lever 14A is provided on one side of the clamp body 12, and a link lever 14B is provided diagonally on the other side. It suffices if it is pivoted at. Further, the link levers 14A and 14B are supported by a penetrating support pin 1.
9 and 20 and a retainer 21, and a spindle pin receiving hole is formed at a predetermined position of each member. The bolt 15 and nut 16 are separate from the clamp body 12, and the bolt 15 is simply inserted into a hole formed in the clamp body 12, and the nut 16 is screwed onto the opposite side to tighten. However, it is also possible to fix either one to the clamp body 12. In the illustrated embodiment, a positioning claw 12B extending inward is integrally formed with the clamp body 12, and as shown in FIG. Bolts 15 and nuts 16 can be tightened to obtain the required clamping force.

According to the ceiling panel mounting structure having such a structure, the clamp holder 11 is positioned with respect to the inclined bracket 10, and the bolt 15 and nut 16 are
By tightening, the clamp body 12 firmly clamps the inclined brackets 10 together. As a result, a pressing force in the direction of the arrow is applied to the ceiling panel 1 as shown in FIG. 2, and the ceiling panels are firmly connected and held together. Here, if a normal positioning fitting material or a fitting uneven portion shown in FIG. 2a is formed on the rear edge of the ceiling panel 1, the connected state will be further ensured.
Next, the installation of the ceiling panel 1 is completed by suspending the hanging portion 13 from the frame in the conventional manner.
On the contrary, there is no problem even if the above-mentioned operation is performed after first suspending the clamp holder from the frame.

Even if the initial tightening force of the bolts 15 and nuts 16 loosens as time passes after the ceiling panel 1 is suspended, the force due to the downward support weight acting on the clamp body 12 will continue to increase the clamp body 1.
Since it acts in the direction of bringing the ceiling panels 2 closer together, the bonded state of the ceiling panels 2 is sufficiently maintained. In other words, the bolts 15 and nuts 16 prevent the clamp body 12 from separating, thereby preventing the ceiling panel 1 from falling off.

As mentioned above, according to the present invention, the installation of ceiling panels is extremely simple, ceiling panels can be connected to each other at the same time, the workability of assembly is greatly improved, and reinforcing beams etc. are not required, making it possible to install ceiling panels easily. No penetrating holes are required and insulation properties are not compromised. Furthermore, since there is no need for reinforcing beams or bolt seats on the internal surface of the refrigerator, it has many advantages, such as eliminating cold air accumulation and preventing localized freezing.
