[Background Art and Problems to be Solved by the Invention]
2. Description of the Related Art In recent years, in residential buildings and the like, light metal aggregates have been used as shafts such as pillars (referred to herein as “shaft members”). Unlike the reinforced concrete or wooden shaft member, this metal shaft member has the advantage that it can be recycled and can be used effectively.
[0003]
With reference to FIG. 4, a conventional heat insulating panel mounting structure in which a heat insulating panel 70 in which a plate-like face material 71 and a heat insulating layer 72 are laminated is attached to a shaft assembly member 81 will be described.
In FIG. 4, first, the two heat insulation panels 70 are brought into contact with the end surfaces from the outdoor side (indicated by reference symbol β), and the side end portions of the respective heat insulation panels 70 are fixed to the shaft assembly member 81 using screws N01. To wear.
Next, a barrel edge 82 is disposed on the side end portion of each heat insulation panel 70, and the drum edge 82 is fixed to the shaft assembly member 81 from above the heat insulation panel 70 using a screw N02.
FIG. 4 also shows a state in which the exterior material 91 is attached to the outdoor side of the trunk edge 82 and the interior material 92 is attached to the indoor side (indicated by the symbol α) of the shaft assembly member 81.
[0004]
However, this heat insulation panel mounting structure has the following disadvantages.
That is, the screws N01 and N02 are driven into the shaft assembly member 81, and the tip end side is exposed in the internal space E of the shaft assembly member 81. The temperature of the exterior material 91 is the temperature on the outdoor side β, and the temperature of the space γ between the heat insulating panel 70 and the interior material 92 is close to room temperature. For this reason, especially in winter, the temperature difference between the space γ and the tips of the screws N01 and N02 is large, and as a result, condensation occurs on the tip side of each screw (the portion exposed to the relatively hot space γ). End up.
[0005]
This condensation occurs constantly when the temperature difference between the outdoor side β and the indoor side α is large, for example, during winter heating, because the indoor side α is high humidity, and moisture due to the condensation is generated by the shaft assembly member. 81 is gradually corroded. Such corrosion not only prevents the shaft member 81 from being recycled, but also causes damage to the shaft member 81 (ie, a decrease in structural strength) when the corrosion is severe.
[0006]
An object of the present invention is to provide a fastener that is exposed to the internal space of a shaft assembly member when the heat insulation panel and the trunk edge are fixed to the shaft assembly member made of metal using a nail or a screw as a fastener. The purpose of this is to prevent the occurrence of condensation on the tip side of the slab.
Another object of the present invention is to prevent the above-mentioned condensation from occurring, thereby preventing the corrosion of the shaft assembly member, thereby preventing the shaft assembly member from being damaged by the corrosion and ensuring the recycling of the shaft assembly member. There is to do.
[0007]
[Means for Solving the Problems]
In the heat insulating panel mounting structure of the present invention, a heat insulating panel in which a face material and a heat insulating layer are laminated on a shaft member made of metal and has a heat insulating layer deficient portion at least at an end, the face material is the shaft. The present invention is applied to the structure attached at the heat insulating layer defect portion so as to face the assembly member, or the structure in which the face material has a plate shape and the plate-like face material is abutted.
[0008]
In the present invention, the heat insulation panel is fixed to the shaft assembly member by the first stopper in the heat insulation layer defect portion. In addition, a crosspiece is disposed in the heat insulation layer deficient portion, and the crosspiece is fixed to the shaft assembly member by a second stopper through the face material. Further, a barrel edge is arranged on the outdoor side of the pier, and the barrel edge is fixed to the pier by a third stopper so that the tip of the barrel edge does not reach the frame assembly member.
[0009]
The present invention can be applied not only to ordinary houses but also to simple buildings that are demolished in a short period of time, and can also be applied to roofs and the like in addition to walls.
In the present invention, as the shaft assembly member, a cross-section having a C-shape, H-shape, U-shape, square, or the like is used, and the material is not particularly limited as long as it is a metal, and iron, stainless steel, aluminum, copper Various materials such as various alloys are used, and those obtained by plating or painting are also used.
When the cross section of the shaft assembly member is C-shaped, H-shaped or U-shaped, the shaft member is constructed in such a direction that the opening is perpendicular to the surface to which the heat insulating panel is attached. An interior base material and an interior material are attached to the indoor side of the shaft assembly member. A plurality of (for example, two) shaft assembly members can be used as a set. For example, a structure in which two shaft assembly members having a C-shaped cross section are brought into contact with each other so that the opening side faces each other, and the mutual contact surfaces are perpendicular to the front surface (or back surface) of the heat insulation panel.
[0010]
In the heat insulating panel in the present invention, the face material and the heat insulating layer are laminated, and the heat insulating layer deficient portion is formed at the end. If this heat insulation layer defect | deletion part is a site | part corresponding to a frame assembly member, it can also be provided in parts (for example, center part) other than the edge part of a heat insulation panel. The heat insulating panel is attached between the shaft assembly members by fixing the face material of the heat insulation layer deficient portion to the shaft assembly members. When the heat insulating panels are adjacent to each other, the face materials at the opposite side end portions of the two heat insulating panels can be abutted with each other, or can be fixed to the shaft assembly member so as to overlap each other.
As the face material, a plate-like face material treated as a fixed length plate such as a plywood or an inorganic board, a sheet-like face material treated as an indefinite length such as paper or a plastic film, or the like is used. If the structural face material described in the specifications of Housing Finance Corporation is used as the face material, a heat-insulating load-bearing wall structure can be constructed.
Specific examples of the face material include plywood, veneer board, structural plywood, particle board, hard board, sizing board, inorganic board such as gypsum and calcium silicate, hard wood cement board, lath sheet, paper board, synthetic resin such as polyethylene and polyester. Examples thereof include films or sheets, liner paper, kraft paper, paper such as calcium carbonate mixed paper, metal foil such as iron, aluminum, and stainless steel, or a laminate thereof.
[0011]
What can be used for conventional heat insulation panels as a heat insulation layer, for example, hard polyurethane foam, isocyanurate foam, styrene foam, polyethylene foam, phenol foam, foamed rubber and other plastic heat insulation materials, glass wool, rock wool and other inorganic materials Fiber-based heat insulating materials, organic fiber-based heat insulating materials such as cellulose fibers, etc. can be used, and these include paper such as liner paper and kraft paper, synthetic resin films such as polyethylene film and polyester film, iron and aluminum, A laminate heat insulating board in which a metal foil such as stainless steel or a laminate to which a vapor deposition layer is added is laminated on one side or both sides can also be used.
A heat insulation layer defect | deletion part can also be created by removing the heat insulation layer of the part corresponding to a frame member of the edge part of the heat insulation panel which consists of a surface material and a heat insulation layer of the same area, for example. Moreover, it can also form by affixing the heat insulation layer with narrow vertical width or horizontal width on a face material.
[0012]
In the present invention, as the pier, one having a low thermal conductivity such as natural wood, synthetic wood (MDF, LVL, etc.) is used.
The pier is arranged along the shaft assembly member, and the heat insulating panel is attached to the shaft assembly member so that the face materials of the opposite side ends of the two heat insulation panels are abutted or overlapped with each other. And is fixed to the shaft assembly member by the second stopper through the face material.
The width of the pier is smaller than the width of the framing member and needs only to have a size that can be accommodated in the heat insulation layer deficient portion. The size is preferably accommodated. Further, the thickness of the crosspiece is appropriately selected, but it is preferable that the thickness of the crosspiece is the same or about half the thickness of the heat insulating layer.
On the other hand, the trunk edge is fixed to the frame assembly member so as to cover the second stopper along the pier. As the body edge, in addition to those having a low thermal conductivity such as natural wood and synthetic wood, a metal having a high thermal conductivity (for example, the same as the above-mentioned shaft assembly member) can be used. It is necessary to attach so that it does not contact 2 fasteners.
[0013]
As the stopper, for example, a screw or a nail is used. The thickness, length, and material of the fastener are appropriately selected according to the material, thickness, etc. of the metal constituting the shaft assembly for the first and second fasteners, and the third fastener. Is appropriately selected according to the material, thickness and the like of the trunk edge. Specifically, as the stopper, in addition to metals such as iron, stainless steel, copper, and aluminum, those made of non-metal such as engineer plastic, FRP, and ceramic can be used.
In addition, a normal screw can be used for the screw, and the screw head may be any shape such as round, pan, flat, cheese, hex, hexagon, square, etc., minus hole, plus hole, hexagon hole on the screw head upper surface It suffices if processing such as a square hole, ULR, LH, etc. is performed and can be screwed by turning with a tool. Further, the shape of the tip of the screw may be any shape that is normally used, such as a cutting edge or a pointed tip. The thread portion may be a full screw or a half screw, and may be any one of a single thread, a double thread, a high / low thread, and the like.
[0014]
The first stopper is only for fixing the heat insulating panel to the shaft assembly member, and preferably the metal material constituting the shaft assembly member so that the tip of each stopper reaches the shaft assembly member. It can be attached so that the tip penetrates through the thickness and the tip is exposed to the inner wall space or the inner space of the shaft assembly member. In the case where the face material is in the form of a sheet such as paper, an adhesive, a pressure-sensitive adhesive, and a double-sided pressure-sensitive adhesive tape can be used as the first stopper.
[0015]
In the present invention, for example, when each of the first to third stoppers is made of a screw having a high thermal conductivity, the heat of the shaft assembly member is transmitted to the first stopper and the second stopper, The heat of the exterior member attached to the trunk edge is transmitted to the third stopper, but the first and second stoppers and the third stopper are thermally insulated by the crosspiece. Even if the trunk edge is made of metal, the thermal conductivity of the pier is relatively small, so heat exchange between the first and second fasteners and the third fastener is limited by the pier. . Therefore, for example, even when the indoor side temperature is high and the outdoor side temperature is low (that is, when the temperature of the frame member is high and the temperature of the exterior material is low), the temperatures of the first and second fasteners The gradient does not become small, and the temperature gradient of the third stopper does not become small, and no condensation occurs on the first and second stoppers.
[0016]
【Example】
An embodiment of the present invention will be described below with reference to FIGS.
As shown in FIG. 1, first, a plurality of longitudinally arranged shaft assembly members 1 (only one is shown in FIG. 1) are provided with two heat insulating panels 2, 2 (in FIG. 1, a part of each side end). Is attached with the end of the face material butted (ie, one left butted to the other right). This heat insulation panel 2 is formed by forming a heat insulating layer 22 made of rigid polyurethane foam on a plate-like face material 21 made of a structural plywood shown as a structural face material in the specifications of the Housing Finance Corporation, It has the heat insulation layer defect | deletion part Q so that the both ends of the plate-shaped surface material 21 may protrude. And each plate-like surface material 21 of the two heat insulation panels 2 is fixed to the shaft assembly member 1 with a first stopper (screw N1) in the heat insulation layer deficient portion Q.
[0017]
In this embodiment, a lip groove steel having a C-shaped cross section is used as the shaft assembly member 1. The shaft assembly 1 is arranged such that the C-shaped opening surface is perpendicular to the mounting surface of the heat insulating panel 2. Although not shown in FIG. 1, the screw N <b> 1 is struck so as to be exposed in the internal space E of the shaft assembly member 1 with an interval in the length direction of the shaft assembly member 1.
[0018]
Next, the wooden pier 3 is accommodated in the space formed by the heat insulation layer deficient portion Q of the opposite heat insulation panel, and the shaft is interposed by the second stopper (screw N2) via the plate-like face material 21. Fastened to the assembled member 1. In this embodiment, the thickness of the pier 3 is the same as the thickness of the heat insulating layer 22, the width is smaller than the width of the shaft assembly member 1, and two heat insulations are made so as not to form a gap between the end surfaces of the heat insulating layers. The width is the same as the width of the space (groove) formed by the layer defect portion Q. Although not shown in FIG. 1, the screw N <b> 2 penetrates the plate thickness of the shaft assembly member 1 with an interval in the length direction of the shaft assembly member 1, and the tip side of each screw is the interior of the shaft assembly member 1. A plurality of hits are made, for example, in rows (1 row, 2 rows, etc.) so as to be exposed to the space E.
[0019]
Further, a barrel edge 4 is arranged on the opposite side (outdoor) of the heat insulating panel 2 to the shaft assembly member 1 side, and a third fastener ( Fastened with screws N3). Here, in this embodiment, the trunk edge 4 is made of wood, and is arranged as a vertical trunk edge so as to overlap with the pier 3. Although not shown in FIG. 1, the screw N3 is struck so as to be spaced apart in the length direction of the shaft assembly member 1 so as not to come into contact with the screw N2, and so that the tip does not reach the shaft assembly member. ing.
[0020]
After fixing the trunk edge 4 in this way, the exterior material 5 is attached from the outdoor side of the trunk edge 4. An interior material 6 is also attached to the indoor side of the shaft assembly 1.
FIG. 2 is a cross-sectional view perpendicular to the length direction of the shaft assembly member 1 showing the mounting structure of the heat insulation panel 1 configured as described above.
In the conventional wall structure, since the body edge is fixed to the frame assembly member, long nails and screws must be used, and the weight of the entire wall acts directly on the nails and screws. In the present invention, when the weight of the exterior material is extremely heavy, there is a risk that the barrel edge may shift downward, but in the present invention, the pier is fixed to the frame member and the barrel edge is fixed. Since the structure is fixed to the pier, nails and screws can be shortened to increase the strength of the support structure.
Although this embodiment is an example of a structure in which a heat insulation layer defect portion is provided at both end portions of the heat insulation panel, a heat insulation layer defect portion may be provided in the center of the heat insulation panel. In this case, the manner of attaching the crosspiece and the trunk edge can be made in the same manner as the panel structure in which the heat insulation layer deficient portions are provided at both end portions of the heat insulation panel.
[0021]
FIGS. 3A to 3D are cross-sectional views perpendicular to the length direction of the shaft assembly member showing the mounting structure of the heat insulating panel different from that in FIG. In these drawings, the same reference numerals as those in FIG. 2 are used for the components other than the pier and the trunk edge, and the exterior material 5 and the interior material 6 are not shown.
In FIG. 3 (A), the thickness of the pier 3a is the same as the thickness of the heat insulating layer 22 as in FIG. 2, but the width of the trunk edge 4a is wider than the width of the pier 3a. Is different. Even if a gap is generated between the heat insulating layer 22 and the pier 3a due to the variation in construction, the mounting structure in FIG. 3A can obtain higher airtightness between the indoor side and the outdoor side.
[0022]
In FIG. 3 (B), the width of the trunk edge 4b is the same as the width of the groove formed by the two heat insulation layer deficient portions Q, as in FIG. It differs from FIG. 2 in that it is thin and part of the trunk edge 4b is accommodated in a groove formed by two heat-insulating layer deficient portions Q. In this case, the screw (N2) for stopping the pier 3b can be shortened and the holding force is increased.
[0023]
In FIG. 3C, the thickness of the crosspiece 3c and the shape of the trunk edge 4c are different from the trunk edge 4 of FIG. That is, in FIG. 3C, the trunk edge 4c has a convex cross section, and the wide portion is formed wider than the groove width formed by the two heat insulation layer deficient portions Q. The shape is housed. FIG. 3 (C) has the structure of FIGS. 3 (A) and 3 (B), and can obtain higher airtightness and holding force between the indoor side and the outdoor side.
[0024]
In FIG. 3D, the thickness of the pier 3b is thinner than the thickness of the heat insulation layer 22, and the width of the trunk edge 4b is the groove width of the space formed in the two heat insulation layer deficient portions Q (the width of the pier 3d). ) Is narrower than. The mounting structure of FIG. 3D has the advantage that the weight of the barrel edge is reduced, the weight of the entire wall is suppressed, and the barrel edge 4d having various widths can be used.
[0025]
