Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an outer wall panel and an outer wall structure.

[0002]

2. Description of the Related Art For an exterior wall panel having a panel frame attached to the back side of a concrete exterior wall material such as GRC, for example, the exterior wall panel is attached to a building frame in order to provide a heat insulating effect. Rock wool was sprayed on the back side, and urethane boards were attached.

[0003]

However, if the thermal insulation is sprayed or attached after the outer wall panel is attached to the building frame, there is a problem that the construction on site requires much time and effort.

Further, since the outer wall panel is fastened to the outer wall material and the panel frame, and the panel frame is connected to a building frame, for example, a steel beam, a heat bridge is generated, and sufficient heat insulating performance can be obtained. There was also a problem that there was no case.

The present invention has been made in view of the above-mentioned conventional problems, and provides an outer wall panel and an outer wall structure capable of saving labor on site and exhibiting high heat insulating performance. As an issue.

[0006]

The above object is achieved by an outer wall panel characterized in that the panel frame is mounted on the rear side of the outer wall material via an outer heat insulating material.

[0007] In this outer wall panel, since the panel frame is attached to the outer wall material via the outer heat insulating material, the exchange of heat between the outer wall material and the panel frame is prevented or suppressed, and therefore, a heat bridge is generated. It becomes difficult to obtain a high heat insulating effect.

[0010] Of course, according to the outer wall panel, since an external heat insulating structure can be used to cover the building frame from the outside with a heat insulating material, internal dew condensation hardly occurs, and a rapid temperature change occurs even when heating and cooling are stopped. This does not occur, and the durability can be increased by protecting the frame.

Moreover, since the heat insulating material is pre-installed in the outer wall panel, if the outer wall panel is installed on site, the heat insulating material can be installed at the same time.
It is possible to save labor on site.

When the panel frame is made of a metal frame, the flow of heat between the outer wall material and the panel frame can be effectively prevented or suppressed by the external heat insulating material.
Further, when the outer heat insulating material is made of a mat-like inorganic fibrous heat insulating material, the fire prevention performance can be enhanced, and the outer heat insulating material can be firmly sandwiched between the outer wall material and the panel frame. In addition, it is possible to omit the on-site refractory treatment for the panel general portion.

Further, the outer wall panel is formed by arranging a plurality of the outer wall panels so as to be adjacent to each other, and the outer heat insulating material of one or both of the adjacent outer wall panels is higher than the rear edge of the outer wall material. In the outer wall structure in which the joints between the adjacent outer wall materials are closed from the back side of the outer wall material by this projection, the heat insulating material is configured in advance as a constituent member of the outer wall panel. The heat exchange between indoors and outdoors can be prevented by this heat insulating material, and a higher heat insulating effect can be obtained. Moreover, the construction only needs to attach the outer wall panel to the site.

Further, when the outer heat insulating materials of the adjacent outer wall panels are provided continuously without being separated from each other, a high heat insulating effect can be obtained even though the heat insulating material is used in advance as a constituent member of the outer wall panel. Obtainable. In particular, when the outer heat insulating material is made of a fibrous heat insulating material, the outer heat insulating materials of the adjacent outer wall panels can be brought into a continuous state by easily buttingly fitting each other.

[0013]

Next, embodiments of the present invention will be described with reference to the drawings.

In the outer wall structure of the first embodiment shown in FIGS. 1 and 4, reference numeral 1 denotes an outer wall panel, and 2 denotes a beam of a building frame. The outer wall panel 1 includes an outer wall material 3 and a panel frame 4.
And an outer heat insulating material 5 as main constituent members. The beam 2 of the skeleton is made of a steel beam, and is made of, for example, an H-beam having upper and lower flanges and a web connecting them.

The outer wall material 3 is made of a concrete-type planar outer wall material such as GRC, and has a thickness of, for example, 60 mm. An anchor 6 is embedded in the outer wall material 3 so that the panel frame 4 can be joined using the anchor 6. The panel frame 4 is made of steel, and an angle iron having an L-shaped cross section is used in a vertical direction.

The outer heat insulating material 5 is made of a mat-like inorganic fibrous heat insulating material such as a rock wool mat. Its thickness is, for example, 20 mm. As shown in FIG. 4, the length in the up-down direction is such that when the outer heat insulating material 5 is arranged along the back surface of the outer wall material 3, the upper edge thereof is the upper edge of the rear surface of the outer wall material 3. The outer wall member 3 is designed to have a dimension protruding above the lower portion and a lower edge protruding below a lower edge on the back side of the outer wall material 3. Also, regarding the length dimension in the left-right direction, in a state where the outer heat insulating material 5 is arranged along the back surface of the outer wall material 3, both side edges are more outward than the right and left side edge portions on the back side of the outer wall material 3. Designed to protrude from In the case of the embodiment, it is designed so as to protrude by half the joint width between the outer wall panels which are attached adjacently in the vertical and horizontal directions or by a somewhat larger dimension.

The outer wall panel 1 has an outer heat insulating material 5 disposed on the back side of the outer wall material 3 and a panel frame 4 disposed on the further rear side of the outer heat insulating material 5.
By using an anchor 6 embedded in the panel frame 4 and tightening it from the back side of the panel frame 4 with a screw fastening member such as a bolt or a nut, the three members are integrally manufactured. The outer heat insulating material 5 is provided between the outer wall material 3 and the panel frame 4.

The outer wall panel 1 is provided with a waterproof material 7 in advance at a portion of the outer wall material 3 which is closer to the rear surface. The water-stopping material 7 is made of an elastic rubber material or the like, and elastically abuts the water-stopping material of the outer wall panel attached adjacently, thereby stopping the joint 9 and stopping the joint 9. Is the same pressure space as outdoors.

The above-mentioned outer wall panel 1 is attached to the frame by fastening the panel frame 4 to the beam 2 of the building frame by fasteners 8 using fasteners 8. Thus, the outer wall is formed by arranging the plurality of outer wall panels in the same manner in the left-right direction and / or the up-down direction. At the same time,
The joints 7 elastically abut each other so that the joint 9 is in a water-stop state, and the outer heat insulating materials 5 and 5 of the adjacent outer wall panels 1 and 1 are provided.
Of the outer wall materials 3 and 3 are closed, and the outer heat insulating materials 5 and 5 of the adjacent outer wall panels 1 and 1 are continuous without being separated from each other. In a state.

A dowel 10 is provided at the upper end of the panel frame 4 of the outer wall panel 1 so as to protrude upward.
A plate 11 with a hole is provided at the lower end of the panel frame 4 of the outer wall panel 1 which is attached adjacent above the outer wall panel 1 so that the dowel 10 is inserted into the hole of the plate 11. By setting, the upper outer wall panel 1 can be easily positioned so as to be flush with the lower outer wall panel. As a result, the upper and lower outer heat insulating materials 5 and 5 are in a continuous state in a good condition.

In the above-mentioned outer wall panel 1 and outer wall structure, since the panel frame 4 is attached to the outer wall member 3 via the outer heat insulating material 5, heat is prevented from flowing between the outer wall member 3 and the panel frame 4. Therefore, heat bridges are less likely to occur, and a high heat insulating effect can be obtained.

Moreover, since the outer heat insulating material 5 is incorporated in the outer wall panel 1 in advance, if the outer wall panel 1 is mounted on the frame, the outer heat insulating material 5 is also mounted at the same time.
Therefore, labor on site can be saved.

Further, since the outer heat insulating material 5 is made of a mat-like inorganic fibrous heat insulating material such as a rock wool mat, the fireproof performance can be improved, and the outer heat insulating material 5 can be connected to the outer wall material 3 and the panel frame 4. , And furthermore, it is possible to omit the on-site fireproof treatment for the panel general part.

In addition, in the outer wall structure formed using the outer wall panels 1, the outer heat insulating materials 5 of the outer wall panels 1 are in contact with each other by attaching the outer wall panels 1. The joints 9 between the outer wall members 3 and 3 of the outer wall panels 1 and 1 adjacent vertically and / or left and right are closed from the back side.
Although it is a constituent member of the above, the exchange of heat inside and outside through the joint 9 can be prevented by the external heat insulating material 5,
An even higher heat insulating effect can be obtained. Moreover, the construction only needs to attach the outer wall panels 1 to the site. Further, since the joint 9 is stopped by the water blocking materials 7, 7, the external heat insulating materials 5, 5 are not wetted by rain or the like.

Further, since the outer heat insulating materials 5 and 5 of the adjacent outer wall panels 1 and 1 are provided in a continuous manner in contact with each other without being separated from each other, there is no place where heat insulation is interrupted in the plane of the outer wall. Although the heat insulating material 5 is configured in advance as a constituent member of the outer wall panel 1, a high heat insulating effect can be obtained.

In the second embodiment shown in FIGS. 5 and 6, in the outer wall panel 1, the edge of the outer heat insulating material 5 is
Is configured not to protrude from the edge on the back side of the camera. In the present embodiment, the outer heat insulating material 5 does not close the joint between the adjacent outer wall materials 3 from behind, but the basic effect is the same as that of the first embodiment. Other configurations are the same as in the first embodiment. In the second embodiment, the outer heat insulating material may be protruded only on the vertical joint side in the same manner as in the first embodiment, or may be formed only on the horizontal joint side in the same manner as in the first embodiment. The outer heat insulating material may be made to protrude at the same time.

Although the embodiment of the present invention has been described above, the present invention is not limited to this, and various changes can be made without departing from the spirit of the invention. For example, in the above embodiment, the outer heat insulating material 5 of the adjacent outer wall panels 1 and 1 is used.
5 are abutted at the widthwise intermediate portion of the joint 9 so as to close the joint 9 from the back side, but only the outer heat insulating material of one adjacent outer wall panel is projected, and the other adjacent The outer heat insulating material of the outer wall panel may not be protruded, so that the joint may be closed from behind by only the outer heat insulating material of the one outer wall material. That is, the position where the outer heat insulating materials of the adjacent outer wall panels are continuously butted without being separated from each other may not be the joint portion, and may be set at a position on the back side of the outer wall material avoiding the joint portion. Is also good. By avoiding the butted portion of the outer heat insulating materials from the joint in this way, the joint can be more reliably insulated.

In the above embodiment, the outer wall panel 1
This shows a case where a concrete-based outer wall material 3 is used, and the present invention is particularly effective when the outer wall material 3 is a concrete-based material. However, the present invention is not necessarily limited to this. Alternatively, the present invention may be applied to an outer wall panel using various types of outer wall materials such as ceramics.
Further, the outer wall panel may be formed using one outer wall material, or a plurality of outer wall materials are combined in a state of being vertically adjacent and / or horizontally adjacent to each other, and the outer wall is formed by a panel frame or the like. The outer wall panel may be formed by integrating materials. Further, the panel frame 4 may have various cross-sectional shapes, and the mounting position and the mounting method on the rear side of the outer heat insulating material 5 may be of various modes.
