Description

Description: TECHNICAL FIELD The present invention relates to a laying structure of a roof panel laid on a roof skeleton for improving heat insulation of a roof of the building, protecting the roof skeleton, and the like. More specifically, the present invention relates to an edge stop structure around a laid roof panel.

[Prior art] Conventionally, a roof panel having heat insulating property is laid on the roof of a building to improve the heat insulating property of the roof and reduce bending stress generated in the roof frame due to a temperature difference between the inside and outside of the building.
Protection of the roof frame is being carried out.

As the rim structure of the roof panel, the following is conventionally employed.

The first is as shown in FIG.
A curb block 3 is fixed to the roof frame 1 with mortar (mortar dango) along the periphery of the roof panel 2 laid on top of each other, and a jaw projecting from the top of the curb block 3 toward the roof panel 2. The edge of the roof panel 2 can be pressed by the part 4.

The second is as shown in FIG.
The periphery of the roof panel 2 laid on top of each other
This is to hit the parapet 5 around the roof.

[Problems to be Solved by the Invention] However, the following problems remain in the conventional rim structure.

First, in the first rim structure, since the jaw 4 above the curb block 3 protrudes above the roof panel 2, a strong wind pressure is applied thereto in a strong wind such as a typhoon. Lie down and roof panel 2
And the roof panel 2 is scattered. Further, even if the curb block 3 does not fall down, the jaw 4 of the curb block 3 merely covers the edge of the roof panel 2 and is not interconnected. Due to the vibration of the roof panel 2,
The roof panel 2 may come off from the jaw 4 of the curb block 3 and fly.

The above problem can be alleviated to some extent by making the curb block 3 heavy and increasing the width of the bottom surface. However, the heavy curb block 3 deteriorates workability, and increasing the bottom width of the curb block 3 requires the roof panel 3. The area where heat insulation and protection cannot be performed is expanded.

On the other hand, in the second rim structure, the peripheral edge of the roof panel 2 is merely abutted against the parapet 5 and is not supported at all, so that the roof panel 3 is more scattered than the first rim structure. There is a problem that easily occurs.

The present invention has been made in view of the above-mentioned conventional problems, and has an object to be solved by providing a roof panel rim structure having excellent wind resistance and excellent heat insulation and protection effects. is there.

[Means for Solving the Problems] Means taken in the present invention to solve the above problems will be described with reference to the drawings. In the invention of claim 1, for example, as shown in FIG. A plurality of rectangular roof panels 2 are connected to each other and laid, and a long edge member 6 having a C-shaped cross section is provided around the laid roof panels 2.

It is something that has taken.

Further, in the invention of claim 2, as shown in FIG. 1, a plurality of rectangular roof panels 2 are connected to each other and laid. A long edge material 6 which is equal to or less than the height of the panel 2
In this case, a means is adopted to provide a roof panel rim structure in which each roof panel 2 located on the periphery and the edge material 6 are connected by a connecting tool 7.

[Embodiment] FIGS. 1 to 3 show an embodiment of the present invention, in which 2 is a roof panel, and 6 is a long edge material.

The roof panel 2 has a rectangular shape, and has a protective material 9 integrally provided on the upper surface of a heat insulating material 8 as particularly clearly shown in FIG.

As the heat insulating material 8 of the roof panel 2, a synthetic resin foam plate is usually used. As this synthetic resin foam board,
For example, extruded expanded polystyrene plate, bead expanded polystyrene plate, expanded polyethylene plate, rigid expanded polyurethane plate,
A foamed vinyl chloride plate or the like is used, but an extruded foamed polystyrene plate is preferable because it is excellent in strength, hardly absorbs moisture, and has a long-term stable heat insulating effect. The thickness of the heat insulating material 8 varies depending on the climatic conditions of the construction area, the required heat insulating performance, and the like.
It is about 0 mm.

Examples of the protective material 9 for the roof panel 2 include a cement mortar plate, a cement concrete plate, a synthetic resin-containing cement mortar plate, a fiber-reinforced cement mortar plate,
Natural stone plates, artificial stone plates, ceramic plates and the like can be mentioned. The thickness of the protection member 9 varies depending on the allowable weight, the rooftop usage, and the like, but is generally about 5 to 50 mm.

The roof panel 2 has a square shape and the size is
In the case of a square, the size is preferably about 300 × 300 to 900 × 900 mm.

As shown in FIG. 2, the roof panel 2 is connected to each other by a connecting member 7 and is laid on the roof frame 1 provided with a waterproof layer 10 on the surface. In FIG. 2, reference numeral 5 denotes a parapet, and reference numeral 11 denotes a level adjusting material for keeping each roof panel 2 horizontal.

As clearly shown in FIGS. 1 and 2, an edge 6 is assigned to the periphery of the roof panel 2 laid on the roof frame 1. The panel and the panel are connected by a connector 7.

As shown in FIG. 1, the edge member 6 in this embodiment is made of a material having a C-shaped cross section, and is provided with its opening facing the roof panel 2 side.

Examples of the edge member 6 made of the C-shaped section material include an extruded product of a metal such as aluminum or stainless steel or a synthetic resin. When the rim 6 is made of a synthetic resin, for example, polypropylene, medium-low pressure polyethylene, nylon, polyester, FRP, vinyl chloride, ABS resin, polystyrene, polycarbonate, polyacetal, or the like can be used.

The rim 6 is long and has a length equal to or longer than at least two roof panels 2. In addition, in order to further enhance the edge stop effect of the roof panel 2, the edge member 6 preferably has a length equal to or longer than the length of the three roof panels 2.

The connecting member 7 is as shown in FIG. 3, and includes a disc-shaped receiving plate 12 and a disc-shaped holding plate 13 slightly larger than the receiving plate 12.
And a screw 14 for fastening the two.

Holes 15 and 16 are provided in the center portions of the receiving plate 12 and the holding plate 13, respectively, and the screw 14 is screwed into the hole 16 through the hole 15. Further, the receiving plate 12 is provided with four semicircular partitioning plates 17 standing at positions where the receiving plate 12 is divided into four equal parts.

In this embodiment, the connecting member 7 is made of metal. In particular, the partition plate 17 of the receiving plate 12 is formed by making a semicircular cut in the partition plate 12 and folding the cut. The metal constituting the connecting member 7 is preferably a metal which is hardly corroded even when exposed to the weather, such as stainless steel and aluminum.

However, the connecting tool 7 in the present invention is not limited to metal, but may be made of synthetic resin as long as necessary strength can be obtained. That is, the connecting member 7 can be an injection-molded product of the same synthetic resin as the synthetic resin that can be used for the edge member 6.

Here, returning to FIG. 1 and FIG. 2, the connection state of the roof panel 2 and the edge member 6 located at the peripheral edge will be described.

At the corner of the heat insulating material 8 of each roof panel 2 located at the peripheral edge, a cut is made at a height substantially equal to the upper end of the edge material 6 on one side.
A portion of the receiving plate 12 sandwiched between the partition plates 17, 17 is inserted into the cut portion 18. That is, one partition plate 17 is sandwiched between the adjacent roof panels 2, and the other two partition plates 17 positioned at right angles to the partition plate 17 are brought into contact with the peripheral edge of the roof panel 2. In this way, approximately 1/4 of the receiving plate 12 is inserted into each cutout 18. Further, the edge member 6 side of the receiving plate 12 enters the inside of the edge member 6 having a C-shaped cross section.

On the other hand, the holding plate 13 straddles two adjacent roof panels and the edge member 6 and is located on the upper surfaces thereof. Then, the screws 14 are inserted through the holes 16 (see FIG. 3) of the holding plate 13 and screwed into the holes 15 (see FIG. 3) of the receiving plate 12 to fasten the two adjacent roof panels. 2 and the upper piece of the edge material 6 are simultaneously held between the receiving plate 12 and the holding plate 13 and are connected to each other.

In the above connection, the height of the edge member 6 is preferably equal to or less than the height (thickness) of the roof panel 2.
That is, it is preferable that the rim 6 does not protrude above the upper surface of the roof panel 2, thereby reducing the positive pressure applied to the rim 6 during strong winds and further preventing the rim 6 from coming off the roof panel 2 due to wind pressure. It can be prevented reliably.

The partition plate 17 of the receiving plate 12 is used for the connecting operation described above.
This facilitates the positioning when the sheet is inserted into the cut portion 18 of the roof panel 2 and is not essential, but is preferably provided to facilitate the connection operation.

Further, one of the four partition plates 17 of the receiving plate 12 is provided with the edge material 6.
Therefore, only three of the partition plates 17 can be used. However, the connection between the roof panel 2 and the edge member 6 located at the above-described peripheral edge, as in this embodiment,
Even if the receiving plate 12 having the four partition plates 17 is used, the connection is not hindered, and if the connecting member 7 of the receiving plate 12 having the four partition plates 17 is used, the roof at the center portion is used. This is preferable because it is convenient for connecting the panels 2 together.

That is, the notch 18 similar to that described above is provided at the corner of each roof panel 2, and the space between the partition plates 17 is formed at the location where the corners of the four roof panels 2 are concentrated as described above. The roof plate 2 at the center can be connected by placing the receiving plate 12 and inserting the corners of the four roof panels 2 between the receiving plate 12 and the holding plate 13. in this case,
The space between the partition plates 17 of the receiving plate is inserted into the cutouts 18 of the four roof panels 2 respectively.

FIGS. 4 and 5 show a second embodiment of the present invention, in which the receiving plate 12 of the connecting member 7 is different from that described in FIGS. 1 to 3. FIG.

That is, the receiving plate 12 in the present embodiment has a shape in which the side to be the roof panel 2 is semicircular, and the side to be the edge material 6 has a shape obtained by bending a rectangular plate material, and is particularly the edge material 6 side. The side is a supporting portion 19 which is bent upward in a C-shape so as to correspond to the inner surface of the edge material 6. Also, there are only two partitioning plates 17 in the direction parallel to the edge material 6, and the cutout portion of the roof panel 2 is provided.
The teeth 20 project upward from the portion of the receiving plate 12 inserted into the inside 18.

When the connecting member 7 having such a receiving plate 12 is used, it cannot be used for connecting the roof panels 2 in the center part.
By 19, the connection between the edge member 6 and the connecting member 7 is further strengthened. In addition, the fastening of the screw 14 causes the teeth 20 to bite into the upper surface of the notch 18 at the corner of the roof panel.
And the connection of the roof panel 2 is further strengthened.

In FIG. 4 showing this embodiment, the case where the edge material 6 and the roof panel 2 are connected at the corner portion of the roof panel 2 is shown. In addition to or instead of this, the center of the side edge of the roof panel 2 is used. It is also possible to connect to the edge material 6 at the portion.

FIG. 6 shows a third embodiment of the present invention, in which the edge material 6 is made of the same material as the conventional curb block 3 (see FIG. 8).
It is a block having a shape with a jaw 4 protruding upward.

Also in this embodiment, the edge material 6 is long as described above, and the cut portion 18 formed at the corner of the roof panel 2 has substantially the same height as the lower surface of the jaw 4 of the edge material 6. Is formed.

The edge member 6 in the present embodiment can be made of concrete or the like, and the weight of the edge member 6 can stabilize the support of the roof panel 2 located on the periphery. Further, in the present embodiment, the partition plate 17 of the receiving plate 12 located on the side of the edge material 6 is used.
Is unnecessary, but in the case of a metal as shown in FIG. 3, the partition plate 17 on the side of the edge member 6 can be folded and used.

FIG. 7 shows another embodiment of the rim 6 used in the present invention, which is almost the same as that shown in FIGS. 1 and 4, except that a recess 21 is formed at the bottom. It has become something.

When the edge material 6 having such a concave portion 21 is used, for example, when the edge material 6 is fixed on the roof frame 1 with a fixing material such as a mortar dango, the fixing material bites into the concave portion 21 so that the fixing force is improved. preferable.
