TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method for forming a curtain wall.
[0002]
[Prior art]
As for the cubic elements constituting a conventional curtain wall, aluminum fins, which are unlikely to generate rust even when exposed to the weather, are often used, and the back side of the aluminum cubic elements is also exposed indoors. .
However, metal such as aluminum is a good conductor of heat, and heat is easily transmitted to the outside through metal parts such as aluminum cubic. For this reason, in the winter season, the cubic is cooled, dew condensation is likely to occur on the exposed portion exposed to the indoor side of the cubic, and there is much waste of air conditioning costs such as heating costs.
Further, since the image as a metal material is exposed to the interior of the room, a cold image may be associated with the appearance of the metal material, so that a warm image is desired.
[0003]
In order to solve the problems of the conventional aluminum cubicle, a wooden cubicle is known (for example, see Patent Document 1).
According to such a cubic, since the cubic itself has a high heat insulating property, it is difficult for cold air to be transmitted to the indoor side, and the occurrence of dew condensation is prevented. In addition, there is an effect that the wooden cubicle is exposed to the interior of the room to make it look better.
[0004]
FIG. 7 shows a schematic view of the side of the cubic as described above. Here, a state where the entire curtain wall 10 receives the wind indicated by the arrow B, which blows toward the indoor direction, is shown.
In this case, the cubic 11 bends toward the indoor side, and deforms as shown by the broken line in FIG. As described above, in order to minimize the deformation due to the deflection of the cubicle 11 when the curtain wall 10 is subjected to the wind, the expected dimension H of the cubicle 11 projecting to the indoor side is particularly suitable for the wooden cubicle. As a result, it was necessary to secure dimensions larger than those made of metal.
[0005]

[0006]
[Problems to be solved by the invention]
If the expected size of the partition constituting the curtain wall is increased, the size of the interior is reduced by that amount, so that the space efficiency in the interior is deteriorated and the appearance is poor.
[0007]
[Problems to be solved by the invention]
Its purpose is to make it look good as a wooden cubicle in appearance, and to prevent heat transfer and condensation of cold air, and to reduce the expected size of the cubic by ensuring sufficient strength. Another object of the present invention is to provide a room that can secure a large indoor space.
[0008]
The present invention has the following configuration to achieve the above object.
That is, according to the method of the present invention, a metal core member extending in the longitudinal direction and a metal core member provided around the metal core member, And a covering wooden member.
By adopting this configuration, since the outer periphery of the cubic is made of wood, conduction of the outside air can be prevented, and dew condensation can be prevented to make the cubic excellent in appearance, and the metal core member has a cubic shape. Since the strength can be increased, the expected size of the cubicle toward the indoor side can be reduced as compared with the case where the cubic is formed only by wood.
[0009]
Further, the wooden member includes one member and another member integrally joined at a joint surface formed along the longitudinal direction.
According to this, by making the periphery of the metal core member sandwiched between one member and another member, it is possible to easily manufacture a wooden cubicle in which the metal core member is sealed.
[0010]
The metal core member includes one member having an engagement portion engageable with each other and another member, and each member of the metal core member is attached to each member constituting the wooden member. In this case, each of the cubic members may constitute one member and another member.
According to this, it is possible to prevent the members constituting the metal core member from being separated from each other, and also to prevent the wooden members to which the members constituting the metal core member are attached from being separated from each other. it can.
[0011]
Further, a concave portion extending in the longitudinal direction is formed on each joining surface of the one member and the other member of the wooden member, and one member or another member of the metal core member is formed in each concave portion of the wooden member. May be stored and attached.
According to this configuration, the metal core member and the wooden member can be easily attached.
[0012]
Further, it is preferable that one member and the other member of the metal core member are provided with screw holes extending in the longitudinal direction, respectively.
According to this configuration, when the bracket used for attaching the cubic to the building frame is attached to the end of the cubic, if the screw hole is used to attach the bracket, the bracket mounting hole is provided on the cubic. There is no need to form such a member, and the device can be easily mounted on a cubic. Further, a through bolt penetrating the cubic in the longitudinal direction can be screwed into the screw hole. By passing such a through-bolt through the whole stake, the strength of the stake can be further increased.
[0013]
Each of the engagement portions of the metal core member is formed in a hook shape.
By adopting such a configuration, when the members constituting the cubicle are integrally mounted, the members can be slid along the joint surface and can be mounted, and the joining surfaces of the wooden members are separated from each other. If the hook-shaped engaging portion is engaged in such a direction as to prevent the movement, the cubic separation can be prevented.
[0014]
The joining surfaces of the one member of the wooden member and the other member are adhered to each other with an adhesive, and a portion other than the engaging portion of the one member of the metal core member and the other member is A gap is provided so as not to contact each other.
That is, the members are joined together by the wooden members. In other words, if an adhesive is applied to the wooden members and the wooden members are joined together, the wooden members have a stronger adhesive force than the metal core members are adhered to each other. it can.
[0015]
In addition, if the wooden member is made of laminated wood, it is possible to provide a cubic having greater strength than the case where the wood material is used. In addition, since the laminated wood is generally less expensive than the solid wood, the cost can be reduced.
[0016]
According to the method of manufacturing a cubic according to the present invention, in the method of manufacturing a cubic constituting a curtain wall, a joining that joins two wooden members that are long columnar members and are made of wood A long metal core member having a groove-shaped concave portion formed on the surface thereof and an engaging portion engageable with each other is formed in the concave portion of each wooden member, and the wooden members are joined. The surface is coated with an adhesive to a portion other than the portion where the metal core member is attached, the engaging portions of the metal core members are engaged, and the bonding surface of the wooden member to which the adhesive is applied is applied. It is characterized in that they are bonded by applying pressure.
According to this method, in a cubicle having advantages of a wooden cubicle such as preventing dew condensation without conducting outside air and being excellent in appearance, a cubic which has increased strength and shortened an expected width to the indoor side. Can be easily manufactured.
[0017]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 shows a front view of the curtain wall. FIG. 2 is a cross-sectional view of the curtain wall cut along the AA plane.
First, the configuration of the entire curtain wall will be described.
The curtain wall 10 has a panel plate 15 (hereinafter, sometimes referred to as a glass plate) such as a glass plate mounted in each frame 13 formed by arranging the cubic 11 as a vertical bar and a horizontal bar (so-called blind). It is configured.
[0018]
Next, the structure of the curtain wall and the cubic will be described with reference to FIG.
The glass plate 15 forming the outer wall surface is sandwiched and fixed between the ridge member 30 and the outdoor side of the ridge 11. The ridge member 30 is a thin plate made of metal, and is mainly made of aluminum or the like. When the pressing edge member 30 is made of aluminum, the strength for holding down the glass can be secured. In addition, since such an edge member 30 is resistant to corrosion, it does not corrode due to wind and rain.
A connecting member 32 for connecting between the ridge 11 and the ridge member 30 made of aluminum is provided between the indoor side surface of the ridge member 30 and the ridge 11.
[0019]
The connecting member 32 is a component provided to connect the metal edge member 30 and the ridge 11, and includes a metal inner portion 34, a metal outer portion 35, an inner portion and an outer portion. And a band-shaped heat insulating member 36 made of a synthetic resin and connected in a longitudinal direction. As described above, by blocking the heat conduction between the ridge 11 and the pressing member 30 by the heat insulating member 36, dew condensation or the like on the cubicle 11 on the indoor side can be prevented. Hook-shaped portions 32a and 30a are provided on the outer side of the connecting member 32 and on the indoor side of the ridge member 30, respectively, and the connecting member 32 and the ridge member 30 are engaged with each other. They are connected by 32a and 30a.
[0020]
On the indoor side of the inside portion 34 of the connecting member 32, two slit portions 38 opened along the longitudinal direction of the cubic 11 are provided. The indoor-side end of the inner portion 34 including the slit portion 38 is inserted into a mounting groove recessed along the longitudinal direction on the outdoor-side end surface 11a of the cubic 11. An unillustrated fixing tool (for example, a screw or the like) is inserted into the slit portion 38, and the connecting member 32 and the ridge 11 are attached by the fixing tool.
[0021]
The glass plate 15 is a double glass composed of two glass plates 15a and 15b. A sealing member 42 and a pressing member 44 are sandwiched between the indoor side of the glass plate 15 and the cubicle 11 and between the outdoor side of the glass plate 15 and the edge member. The holding member 44 holds the glass plate 15, and the sealing member 42 prevents water from entering between the ridge 11 and the pressing member 30.
[0022]
It should be noted that the attachment structure between the cubic member 11 and the ridge member 30 and the attachment structure between the blind stitch 12 and the ridge member as described above employ exactly the same structure. And description is omitted.
[0023]
Next, the partition 11 will be described.
The cubic 11 has a configuration in which a wooden member 50 made of wood is arranged on an outer peripheral portion, and a metal core member 52 made of metal such as iron or aluminum is arranged on a central portion.
In addition, although the wooden member in this embodiment employs a laminated wood, it may be a glued wood instead of a laminated wood.
[0024]
The wooden member 50 is formed by bonding two pillar-shaped members (one member 50a and another member 50b) extending along the longitudinal direction and bonding them together. The joining surface 55 where the two members 50a and 50b are joined is formed along the expected width direction of the cubic.
[0025]
At the center of the joint surface 55 of each of the wooden members 50a and 50b, there are provided concave portions 56a and 56b formed along the longitudinal direction so as to be recessed in a direction away from the facing member.
In other words, it can be said that a hole 56 formed so as to penetrate in the longitudinal direction is formed in the central portion of the integrally formed wooden member 50.
[0026]
The metal core member 52 provided at the center of the wooden member 50 is disposed integrally with the two members 52a and 52b engaged with each other.
In the recesses 56a, 56b of the two wooden members 50a, 50b, metal core members 52a, 52b formed so as to be engageable with each other are housed and attached.
The metal core members 52a and 52b are mounted in the recesses 56a and 56b by screws 59 such as wood screws. However, the metal core members 52a and 52b may be attached using an adhesive, or the screws 59 and the adhesive may be used in combination.
[0027]
The shape of the metal core member will be described.
The metal core members 52a and 52b are provided on the base member 60 mounted on the inner wall surfaces of the concave portions 56a and 56b of the members 50a and 50b of the wooden member 50, and protrude toward the metal core member facing the base member 60. The projection 62 has a hook-shaped portion 64 projecting in a direction perpendicular to the projection 62, that is, a direction parallel to the joining surface 55, and a screw hole 66 formed in the center of the projection 62. ing.
[0028]
Both ends of the base 60 in the width direction (prospect direction of the cubic) project along the rising portions of the recesses 56a and 56b toward the facing metal core member side to form a thick portion 69 formed to be thick. Is formed.
Further, a hole 71 for screwing a self-tapping screw is formed in the thick part 69 of the present embodiment.
[0029]
The protruding portion 62 is provided at a position shifted by a predetermined distance from the vicinity of the center of the base portion 60 in the width direction (estimated direction of the cubic) to the end side.
At this position, the hook portions 64 of the metal core member at the facing positions are arranged in the direction facing each other, so that the hook portions 64 are engaged with each other and joined.
[0030]
When the wooden members 50a and 50b are joined to each other, the metal core members 52a and 52b (tip portions of the thick portions 69) are formed with a slight gap x without abutting. Good.
That is, the joining between the wooden members 50a and 50b is made very firmly by the adhesive, but the joining between the metals becomes very weak only by the adhesive unless welding, brazing or the like is performed. When the metals having low adhesive strength are in contact with each other, the bonding between the joining surfaces of the wooden members 50a and 50b on the same plane as the contact surface of the metal can be easily peeled off. The metal core members are provided so as not to contact each other.
[0031]
Note that, in the metal core member 52, the hook-like portions 64, which are engagement portions that engage with each other, do not need to be formed continuously in an elongate direction, for example, at a predetermined interval in the longitudinal direction of the metal core member. The hook portions 64 may be formed every other time.
[0032]
Next, the upper or lower end of the cubic will be described with reference to FIG.
As shown at the upper or lower end of the ridge 11, the length of the metal core member 52 in the longitudinal direction is formed to be shorter than the length of the wooden member 50 in the longitudinal direction by y.
The difference y between the length of the wooden member 50 and the length of the metal core member 52 is such that even when the metal core member 52 thermally expands due to a temperature change, the metal core member 52 is positioned on the upper or lower surface of the wooden member 50. It is preferable that the length is set so as not to protrude from the projection.
[0033]
The upper end and the lower end of the cubic 11 need to be attached with a bracket (metal fitting for mounting the skeleton) 74 for attaching to the skeleton (not shown) of the building. It is preferable that the metal core member 52 be provided to save time and effort when attaching the bracket 74.
That is, in the case of a wooden cubicle without a metal member as a core as in the conventional case, it was necessary to use a wood screw for mounting the bracket or to drill a hole for passing a bolt. However, according to the present embodiment, the process for attaching the bracket 74 does not have to be performed on the cubicle 11.
[0034]
The bracket 74 shown in FIG. 3 has a shape obtained by bending a plate-shaped metal piece at a right angle. One surface 74a is a mounting surface for the cubicle 11, and the other surface 74b is orthogonal to the one surface 74a. Is the mounting surface of the building to the skeleton.
[0035]
The attachment of the bracket 74 will be specifically described.
A bolt 76 is screwed into the screw hole 66 of the metal core member 52 and screwed. The upper end or the lower end of the bolt 76 is inserted into a through hole 77 formed in the bracket 74, penetrated, and fastened by a nut 78.
Further, a small hole portion 79 for screwing the tapping screw 80 is formed in the bracket 74. The tapping screw 80 screwed into the small hole portion 79 penetrates into the hole portion 71 formed in the thick portion 69 of the metal core member 52 while cutting a screw groove, and is screwed with the metal core member 52. For this reason, the bracket 74 is firmly fixed to the post 11.
[0036]
It is preferable that the length of the bolt 76 is formed so as to penetrate the entire length of the ridge 11. That is, the strength of the cubic 11 is increased by using a bolt 76 longer than the cubic 11 as a core material.
[0037]
Further, the metal core member 52 is provided so as not to protrude from the end of the wooden member 50, and the end of the metal core member 52 and the end of the wooden member 50 are connected so that the metal core member 52 is not exposed. It is also suitable to insert a wooden filling member between them (not shown). In FIG. 3, the shape is such that wood is embedded in the portion of y.
In such a case, the bracket 74 for attaching the building to the skeleton may be attached to this wooden filling member with a wood screw or the like. In this way, by completely covering and hiding the metal core member with wood, the appearance can be further improved.
[0038]
Next, a method of manufacturing the cubic device according to the above-described embodiment will be described with reference to FIGS.
First, as shown in (a), two long columnar wooden members 50 made of laminated wood are prepared. Here, the facing surfaces of the members 50a and 50b are formed as a joining surface 55 to be joined to each other.
Next, as shown in (b), concave portions 56a and 56b, which are grooves for accommodating the metal core member 52 along the longitudinal direction, are formed in the central portion of the joining surface 55 of each member 50a and 50b. .
[0039]
The metal core member 52 is formed by extrusion or the like separately from the wooden member 50 so as to have a shape capable of engaging with each other (c).
[0040]
Subsequently, as shown in (d), the bases 60 of the metal core members 52a, 52b are fitted into the concave portions 56a, 56b of the members 50a, 50b of the wooden member 50, and the respective members 50a of the wooden member 50 are fitted with wood screws or the like. , 50b and the respective members 52a, 52b of the metal core member 52 are fixed.
Subsequently, an adhesive is applied to the joining surface 55 of the members 50a and 50b of the wooden member 50 to which the members 52a and 52b of the metal core member 52 are attached.
Then, as shown in (e), the wooden members 50a and 50b are pressed together by applying pressure while the hook portions 64 of the metal core member are engaged with each other so that they cannot be separated from each other.
This completes the production of the cubic 11.
[0041]
Next, another embodiment of the metal core member different from the above-described embodiment will be described. Note that, here, only the cubic is illustrated, and the configuration as the curtain wall is not illustrated. In addition, the same components as described above are denoted by the same reference numerals, and description thereof will be omitted.
[0042]
The metal core member 85 shown in FIG. 5 is not provided with an engaging portion, and instead employs a structure for further increasing the strength of each metal core member. Specifically, the metal core members 85a and 85b do not have the protrusions 62 and the hook-like portions 64 shown in FIG. 2 and have a plate-like steel material between the base portion 60 and the thick portion 69. Is formed.
A steel material 88 that is stronger than the metal core member 85 is stored in the steel material storage recess 86. The steel material 88 is formed in a long plate shape, and is attached to the metal core member 85 by screws 89.
By providing such a metal core member 85, the strength of the entire metal core member is increased, so that the expected size can be further reduced.
[0043]
Further, the curtain wall constituting each of the screens as described above is not limited to the configuration in which the glass plate 15 is fixed by using the aluminum edge member 30 as shown in FIG.
That is, as shown in FIG. 6, the ridge member that sandwiches the glass plate 15 may be configured as a wooden ridge member 90 in a curtain wall. 6, the same components as those shown in FIG. 2 are denoted by the same reference numerals, and description thereof is omitted.
[0044]
Note that the present invention has been described as a cubic. However, this is not limited to a case where the curtain wall is used as a vertical crossbar, but is a concept including a case where it is used as a horizontal crossbar (so-called blind).
[0045]
Although the present invention has been described in various forms with reference to the preferred embodiments, the present invention is not limited to the embodiments, and it goes without saying that many modifications can be made without departing from the spirit of the invention. .
