[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a metal roof installation structure in which a roof material is installed in a tight frame on a roof base.
[0002]
[Prior art]
Generally, the roof is affected by external factors such as outside air temperature, solar radiation heat, wind and rain, etc., so it is necessary to reduce the influence on the indoor environment by filling the insulation between the roofing material and the roof base. . In particular, since the roof surface of a metal roof is likely to become high temperature, it is important to perform heat insulation using a heat insulating material or the like.
[0003]
Since buildings with such metal roofs are laid out in various sizes and uses such as houses, factories, and gymnasiums, the shape of the roofing material is also diverse. Therefore, in recent years, the shape of the heat insulating material disposed between the roof material and the roof base tends to be diversified in correspondence with such various roof materials.
[0004]
[Problems to be solved by the invention]
However, since the heat insulating material is generally formed of a very light material such as a synthetic resin foam material, it may be displaced during installation by simply placing it on the roof base, and the wind blows. And easily scatter. In such a case, it is necessary to return the displaced heat insulating material to the original position, or to collect the heat insulating material scattered by the wind, and the working efficiency is significantly reduced.
[0005]
Therefore, it is required to fix the heat insulating material to the roof base surface. Especially when the shape of the heat insulating material is diversified as described above, in order to fit it with the tight frame and other supporting members successfully, There was a situation that the heat insulating material had to be fixed by processing the shape or taking troublesome work.
[0006]
The present invention has been made in view of the circumstances as described above, and is a metal roof that can easily fix a heat insulating material to prevent displacement movement during laying work and scattering by wind, thereby improving work efficiency. It aims at providing the installation structure of.
[0007]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the metal roof laying structure according to the present invention has a tight frame having a plurality of peak portions at a predetermined interval in the flow direction of the roof gradient and in a horizontal direction perpendicular to the flow direction. It is fixed on the roof base in a state that is continuous in the direction, a heat insulating panel made of foamable resin is placed between the upper and lower tight frames, and the roofing structure is installed on the tight frame. The heat insulation panel is held on the roof base by locking a plurality of connecting projections formed on at least one of the water-side and water-side edges to the peak portion of the tight frame. It is characterized by that.
[0008]
According to the present invention, the heat insulation panel placed on the roof base is held on the roof base by locking at least one of the connection protrusions on the water upper side or the water lower side to the mountain portion of the tight frame. As a result, it is possible to prevent the insulation material from shifting during the laying operation and from being scattered by the wind.
[0009]
Further, in the metal roof laying structure according to the present invention, the heat insulating panel includes connection protrusions on both the water upper side and the water lower side, and the length in the flow direction of the heat insulation panel excluding the water upper connection protrusion is It is characterized by being formed so as to be less than the inner method between tight frames.
[0010]
In other words, this metal roof laying structure is such that the heat insulation panels are placed in a row between the upper and lower tight frames fixed continuously in the horizontal direction. In this case, in order to lock the connection projections of the heat insulation panel to the peak portions of the upper and lower tight frames, first, the water-side connection projections are first locked to the water-side tight frame, and then the underwater side The connecting protrusion is locked to the underwater tight frame, and is slightly lowered in the flow direction. As a result, the water-side and water-side connection protrusions of the heat insulation panel are fixed to the upper and lower tight frames to prevent the wind from scattering.
[0011]
Furthermore, in the installation structure of the metal roof according to the present invention, the heat insulating panel includes connection protrusions on both the water upper side and the water lower side, and the plurality of heat insulating panels are connected to the water upper connection protrusion and the water lower side. The protrusions are connected to each other in the flow direction and the tight frame fixing interval in the flow direction is such that the connection protrusions at the upper end and the connection protrusion at the lower end of the plurality of connected heat insulating panel materials are respectively It is set so that it may become the space | interval which can be latched to the peak part of each tight frame.
[0012]
That is, this metal roof laying structure is one in which a plurality of heat insulation panels are placed between upper and lower tight frames fixed continuously in the horizontal direction. In this case, the plurality of heat insulation panels are connected in the flow direction by fitting the water-side connection protrusions and the water-side connection protrusions of each heat insulation panel. Further, the upper and lower connecting protrusions of the plurality of connected heat insulation panels are respectively held on the top and bottom of the tight frame and held on the roof base. Thereby, a heat insulating material is fixed on a roof base | substrate, and scattering by a wind etc. is prevented.
[0013]
As a specific configuration of the connection protrusion in the metal roof installation structure, the connection protrusion on the water upper side has a substantially trapezoidal cross section having the same bottom surface as the heat insulation panel main body portion, and the connection on the under water side It is preferable that the protrusion is formed so as to have a concave portion having an inverted concave cross section that covers the convex portion from above.
[0014]
According to this, the heat insulation panels placed in the flow direction are only subjected to the operation of covering the water-side connection protrusion of the water-side heat insulation panel with the water-side connection protrusion of the water-side heat insulation panel. Since each can be connected, the number of construction steps can be reduced, and the work of placing the heat insulation panel becomes easy.

The illustrated roofing material 1 is corrugated in a cross-sectional tile shape and is formed of a coated steel plate. A heat insulating panel 3 is placed between the upper and lower tight frames 2 fixed on the roof base 4.
[0019]
The heat insulation panel 3 is a molding material made of a foamable resin. The heat insulating panel 3 has a top surface side of the main body 31 formed in a cross-sectional tile shape corresponding to the cross-sectional shape of the roofing material 1, and peak portions 31 a provided corresponding to the intervals between the peak portions 21 of the tight frame 2. Yes. In addition, the bottom surface side of the main body 31 is formed of a smooth surface along the four roof foundation surfaces. Both side edges of the main body 31 are formed so that a tile-shaped cross section is continuous on the top surface side when a plurality of the heat insulating panels 3 are placed in the horizontal direction.
[0020]
The heat insulation panel 3 is formed with a plurality of connection protrusions 32 and 33 on both the water-side and water-side edges of the main body 31. The connection protrusions 32 and 33 are formed at the positions of the peaks 31a of the main body 31, respectively.
[0021]
Furthermore, the heat insulation panel 3 is formed so that the length A in the flow direction of the heat insulation panel 3 excluding the water-side connecting projection 32 is equal to or less than the inner method between the upper and lower tight frames 2 (see FIG. 2). .
[0022]
Such a heat insulation panel 3 is placed between the upper and lower tight frames 2 by the following procedure. As shown in FIG. 1, the fixing interval between the tight frames 2 is set to approximately the length of one heat insulating panel 3 to fix the tight frames 2 on the roof base 4. Between the tight frames 2, the heat insulating panels 3 are continuously placed in a row.
[0023]
At this time, each heat insulation panel 3 is mounted so that the peak portion 21 of the tight frame 2 positioned on the water side and the connection protrusion 32 on the water side are locked with each other. First, the water-side connecting projection 32 is inserted into the tight frame 2 from obliquely below. When the water-side connecting projection 32 is fitted into the peak portion 21 of the tight frame 2 and the edge of the main body 31 comes into contact with the peak portion 21, the heat insulation panel 3 is lowered along the roof base 4, The connecting projection 33 is inserted into the peak portion 21 of the tight frame 2 located on the water side. Then, by slightly lowering the main body 31 of the heat insulating panel 3 in the flow direction, the underwater connecting projection 33 is engaged with the peak portion 21 of the tight frame 2.
[0024]
By forming the water-side connecting projection 32 a little longer than the water-side connecting projection 33, the heat-insulating panel 3 has both the connecting projections 32, 33 locked to the peaks 21 of the upper and lower tight frames 2. And held on the roof base 4. Thus, since the heat insulation panel 3 latched by the tight frame 2 on both the upper and lower sides is stable on the roof base 4, it is prevented from being scattered by the wind during the laying operation.
[0025]
By repeating this procedure, the heat insulating panels 3 are placed in order from the eaves side on the roof base 4 toward the ridge side. After the heat insulation panel 3 is placed on the roof base 4, the roof material 1 is fixed on the tight frame 2. At this time, the roof material 1 is positioned such that the cross-sectional shape thereof matches the tile shape on the top surface side of the heat insulating panel 3. Therefore, the roof material 1 can be easily installed.
[0026]
As described above, in the first embodiment, the fixing interval between the upper and lower tight frames 2 is set to the length of one heat insulating panel 3. However, the fixing interval of the tight frame 2 can be further expanded depending on load conditions such as wind load and snow load. In this case, if a metal roof is installed using the same members as those used in the first embodiment, a new heat insulating panel or the like is not required separately, and the economy is improved. Therefore, in the following second embodiment, a metal roof laying structure in which the same heat insulating panel 3 as described above is used and the fixing interval of the tight frame 2 is further expanded will be described.
[0027]
FIG. 4 is a perspective view showing a metal roof laying structure according to the second embodiment. The tight frame 2 fixed in the flow direction of the roof slope is the same as the tight frame 2 in the first embodiment, and the trapezoidal peaks 21 are formed at predetermined intervals. As shown in the figure, the fixed interval of the tight frame 2 is set to approximately twice the length of the fixed interval in the first embodiment. The tight frame 2 is fixed with screws or the like on the roof base 4 in a state of being continuous in the horizontal direction.
[0028]
Two heat insulation panels 3 are placed between the upper and lower tight frames 2 in the flow direction. Here, the fixing interval between the tight frames 2 in the flow direction is such that the upper and lower connecting protrusions 32 and 33 are connected to each other at the peak portions 21 of the upper and lower tight frames 2 in a state where two heat insulating panels 3 are connected. It is the interval which can be locked to. That is, the length of the connecting portion of the connecting protrusions 32 and 33 when the heat insulating panels 3 are connected corresponds to the width of the tight frame 2.
[0029]
Thus, it is the convex part 321 and the concave part 331 which were formed in the connection protrusions 32 and 33, respectively, which can connect the upper and lower heat insulation panels 3. FIG.
[0030]
The water-side connecting projection 32 formed on the heat insulating panel 3 includes a convex portion 321 having the same bottom surface as the main body 31. The convex portion 321 protrudes from the distal end side of the connecting projection 32 having a substantially trapezoidal cross section.
[0031]
On the other hand, the connecting projection 33 on the water side is provided with a concave portion 331 having a reverse concave shape in cross section that covers the convex portion 321 from above. The inner peripheral surface of the concave portion 331 is formed to match the outer shape of the convex portion 321. As a result, the water-side connection protrusion 32 and the water-side connection protrusion 33 of the heat insulating panel 3 can be fitted into each other.
[0032]
Further, in a state where these heat insulating panels 3 are connected, each of the upper connecting protrusion 32 and the lower connecting protrusion 33 is held on the roof base 4 by engaging with the peak portion 21 of the tight frame 2. Yes.
[0033]
In the present embodiment, such a heat insulating panel 3 is placed between the upper and lower tight frames 2 in the following procedure.
[0034]
First, the connecting projection 33 on the underwater side of the underwater heat insulating panel 3 is inserted and locked obliquely from above to the mountain portion 21 of the tight frame 2 located on the underwater side.
[0035]
Subsequently, the water-side connection projection 32 of the water-side heat insulation panel 3 is inserted and locked obliquely from below to the peak portion 21 of the tight frame 2 located on the water side.
[0036]
And the connection protrusions 32 and 33 located in the intermediate part of the water-side heat insulation panel 3 and the water-side heat insulation panel 3 are mutually fitted. At this time, the connection protrusion 32 on the water side of the water-side heat insulation panel 3 is fitted on the connection protrusion 33 on the water side of the water-side heat insulation panel 3 so as to cover it.
[0037]
With the connection protrusions 32 and the connection protrusions 33 fitted, the water-side and water-side heat insulation panels 3 are lowered along the roof base 4 at the same time. Is in close contact with the roof base 4, and the upper and lower connection projections 32 and 33 of the heat insulation panel 3 are engaged with the peaks 21 of the upper and lower tight frames 2 and held on the roof base 4. In this way, each heat insulation panel 3 hold | maintained on the roof base | substrate 4 prevents shifting during a laying operation | work and scattering by a wind.
[0038]
After repeating such a procedure and placing the heat insulation panel 3 on the roof base 4, the roof material 1 is fixed on the tight frame 2 and installed. At this time, the roof material 1 is positioned so that the cross-sectional shape thereof matches the tile shape on the top surface side of the heat insulating panel 3, and the laying operation is easy. And between the roofing material 1 and the roof base | substrate 4 is filled with the heat insulation panel 3, and the roof in which the roofing material 1 was wound can obtain heat insulation performance.
[0039]
In addition, when the fixing interval of the tight frame 2 is further expanded, the connection protrusions 32 and 33 of the heat insulation panel 3 are fitted and connected to each other in the same manner as described above, and the heat insulation panel placed between the tight frames 2 is connected. It is also possible to increase the number of the three flow directions.
[0040]
As described above, the metal roof laying structure according to the present invention can be used when the heat insulation panels 3 are placed in a single row between the tight frames 2 or when the heat insulation panels 3 are placed in a plurality of rows. In addition, it is possible to suitably carry out by preventing scattering by wind during the laying operation. In any case, the same heat insulating panel 3 can be used, and it is not necessary to prepare a new heat insulating panel separately.
[0041]
【The invention's effect】

The heat insulation panel is held on the roof base by locking the ridge to the peak portion of the tight frame. In this case, since the connection protrusion is provided integrally with the heat insulating panel, the heat insulating panel can be held on the roof base without increasing the number of parts, and scattering due to wind during installation work can be prevented.
[0042]
In addition, when a plurality of connection protrusions are formed on both the water-side and water-side edges of the heat insulation panel, the heat insulation panel can be more stably fixed to the tight frame.
[0043]
Furthermore, when the water-side connection protrusion and the water-side connection protrusion of such a heat insulation panel are formed in a shape that can be fitted to each other, a plurality of heat insulation panels placed in the flow direction are connected to each other. It becomes possible to connect. Therefore, even when the fixed interval of the tight frame is widened, the metal roof can be installed using the same heat insulating panel, and the economic efficiency is improved. In this case, the fixing interval of the tight frames in the flow direction is an interval at which the connecting projections at the upper ends and the connecting projections at the lower ends of the plurality of connected heat insulating panels can be locked to the mountain portions of the upper and lower tight frames, respectively. Thus, the connected heat insulation panel is hold | maintained on a roof base | substrate by each upper and lower tight frames, and a slippage movement and scattering by a wind are prevented.
