Description

  The present invention is a base pier for attaching various building interior members such as wooden shafts (trunk edges and studs) for gypsum boards, slats and curtain boxes arranged around sashes to building concrete of buildings. Related to heat insulation measures.

  Conventionally, when the building concrete of a building is finished with interior members such as gypsum board, wallboard, curtain box, etc., as shown in FIG. The pier 1 is arranged. If it does in this way, since it is necessary to support the pier 1 in the state which floated by the thickness of the spraying insulation material layer from the frame concrete 5, the mounting structure of the pier 1 to the frame concrete 5 becomes complicated, and the spraying insulation material (Hard urethane foam) The spray insulation work of 6 is also complicated, and the pier 1 is positioned on the indoor side by the thickness of the spray insulation layer, and the interior space is narrowed. Problems arise.

In order to solve the problem that this indoor space becomes narrow, as shown in FIG. 25, when attaching the pier 1 in front of the frame concrete part and performing the spray insulation work of the frame concrete in the post-construction, The spray insulation material (rigid urethane foam) 6 will not be arranged directly under the pier 1, and the pier 1 also has a certain heat insulation performance, and although the heat insulation performance on the entire heat insulation surface can be secured, for example, When comparing the thermal conductivity with the rigid urethane foam used for spray insulation work, the thermal conductivity of the pier (3 types) is 0.19 W / m · k, and the thermal conductivity of the rigid urethane foam is 0.026 W. The pier has a thermal conductivity of about 7.3 times that of / m · k, and its thermal insulation performance seems to be very low.

  The above two points have no significant influence on the heat insulation performance of the entire building, but it is not preferable in terms of performance although it is a local decrease in heat insulation performance due to the small area occupied by the pier.

  By the way, vacuum heat insulating material (heat insulating material with reduced pressure inside a sealed container formed of a gas barrier film such as resin film or aluminum foil), which is widely used for refrigerators, has heat insulation performance compared to spray heat insulating material. However, even with a thickness of about 5 mm, it has a heat insulation performance comparable to 50 mm of rigid urethane foam.

Therefore, it is considered that a local heat insulation performance degradation due to a small area occupied by the pier can be avoided by arranging a vacuum heat insulating material having a thickness of about 5 mm immediately below the pier. However, when vacuum insulation material is placed directly under the pier, nails are attached to the pier, such as wooden shafts for the gypsum boards (both edges and studs), sashes and curtain boxes placed around the sash. When fixing with a screw or a screw, the gas barrier film of the vacuum heat insulating material may be damaged by a screw or a nail.

  In addition, when using a vacuum heat insulating material as a heat insulating material for a building, a technique that can suppress deterioration of the heat insulating performance of the entire heat insulating panel even if nailing or cutting is already known from Patent Document 1. It has been.

However, in this known technique, a heat insulating material and a cover film covering the heat insulating material are arranged at a plurality of locations on the flat base film, the area where each heat insulating material is arranged is decompressed, and the cover film is fixed to the base film at the periphery. The first vacuum heat insulating material having a vacuum heat insulating portion having a constant height in structure, and the plurality of vacuum heat insulating materials formed in the first vacuum heat insulating material by the vacuum heat insulating portion in the arrangement, shape and dimensions of the vacuum heat insulating portion. A second vacuum heat insulating material with the same configuration set to be fitted in the recess between the two parts is faced, and the vacuum heat insulating part of the second vacuum heat insulating material is fitted between the vacuum heat insulating parts of the first vacuum heat insulating material. The first vacuum heat insulating material and the second vacuum heat insulating material are fixed to each other to form a panel shape, and each vacuum heat insulating portion has an area of about 30 to ²⁰⁰ mm square, or about 10 to 400 cm ^2. It is said .

  Therefore, when nails are driven in, the deterioration of the heat insulation performance of the heat insulation panel as a whole can be suppressed to a small extent, but it is placed directly under the pier having a width of about 50 mm at most, and the local heat insulation due to the small area occupied by the pier It is completely unsuitable for use as a vacuum heat insulating material that avoids performance degradation.

  Invention of Claim 8 is the heat insulation structure of a pier using the heat insulating material for piers of Claim 4 or 5, Comprising: The heat insulating material for piers of Claim 4 or 5 is the building concrete of a building The metal protection plate is buried in the state where it is exposed on the surface of the concrete frame, the pier is fixed on the metal protection plate with an adhesive, and the spray insulation is applied to the surface of the frame concrete. It is constructed in a state where it is exposed from the spraying insulation layer, and building interior members such as wooden shafts, slats and curtain boxes are fixed to the pier with screws or nails.

  Invention of Claim 9 is the heat insulation structure of the pier using the heat insulator for piers of Claim 6, Comprising: The heat insulator for piers of Claim 6 is a metal protection board to the concrete of a building Is exposed on the surface of the frame concrete, and a heat insulating sheet is interposed between the cap nut and the L-shaped bracket for attaching the piercing screw to the cap nut, and the rise of the opposing L-shaped bracket The pier placed between the pieces is fixed on the metal protective plate by bolts passing through them and the nuts screwed to them, and the spray insulation is sprayed on the surface of the concrete frame. It is constructed in a state where it is exposed from the heat insulating material layer, and building interior members such as wooden shafts, slats and curtain boxes are fixed to the pier with screws or nails.

  According to the first aspect of the present invention, there is provided a base heat insulating pier for preventing damage to the vacuum heat insulating material due to screws or nails driven into the pier between the base pier and the vacuum heat insulating material disposed on the back surface thereof. Because it is provided with a metal protective plate, it can be handled in the same way as a conventional base pier, and after bonding the base heat insulating pier to the frame concrete, on the pier, When screwing or nailing building interior parts such as wooden shafts (both edges and studs) for gypsum boards, sashes around sashes, curtain boxes, etc., the screws and nails are inadvertently driven into the vacuum insulation. There is no fear. Therefore, as in the past, after fixing the pier to the concrete frame, even if the spray insulation work is performed, the heat insulation effect by the vacuum heat insulating material arranged under the pier will surely be exhibited, depending on the micro area occupied by the pier A local decrease in heat insulation performance can be reliably avoided.

  The heat insulating pier for ground according to the invention of claim 2 is provided with a first plate portion bent at a substantially right angle to the back surface side and a nail hole folded at a substantially right angle from the front end on both sides of the metal protection plate. Since the support plate composed of the second plate portion is bent and connected, even if an external force acts in the direction of pressing the pier against the surface of the concrete frame for some reason, the first of the support plate The force is transmitted from the plate part to the frame concrete, and the load applied to the pier can be supported by the support plate, so the vacuum heat insulating material is not crushed and the thickness of the vacuum heat insulating material can be kept constant. .

  In addition, even when the frame concrete is a vertical surface such as a wall surface or a beam side surface, by fixing the second plate part to the vertical surface with concrete nails, the building interior base material can be securely fixed, and the building interior base material Even if a tensile force acts on the material, there is no possibility that the base material for building interior will be peeled off from the concrete. Therefore, it is suitable when the building interior member fixed to the pier with screws or nails is a curtain box in which a tensile force acts every time the curtain is opened and closed.

  According to the invention described in claim 3, since the vacuum heat insulating material is housed in the rectangular metal case having a rectangular cross section, for some reason, the pier is pressed against the surface of the frame concrete against the base heat insulating pier. Even if the external force is applied, the force is transmitted from the rectangular cylindrical case to the concrete frame, and the load applied to the pier can be supported by the rectangular cylindrical case, so the vacuum insulation is crushed. Therefore, the thickness of the vacuum heat insulating material can be kept constant.

  In addition, since the surface side plate of the metal square tube case functions as a metal protective plate to prevent damage to the vacuum heat insulating material by screws or nails driven into the pier, the building interior members are screwed into the pier. Or when fixing with nails, there is no risk of inadvertently driving a screw or nail into the vacuum heat insulating material, and the heat insulating effect inherent to the vacuum heat insulating material can be reliably exhibited, and the local area due to the small area occupied by the pier A decrease in heat insulation performance can be reliably avoided.

  In addition, since the projecting pieces with nail holes projecting flush with the back side plate part are connected to both sides of the back side plate part of the rectangular tube case, the surface of the concrete frame looks like a wall surface or a beam side surface. Even if it is a vertical surface, by fixing the projecting piece with a nail hole to the surface of the frame concrete with concrete nails, even if a tensile force acts on the base insulation frame, the base insulation frame will be removed from the frame concrete. There is no risk of peeling.

  According to the invention described in claim 4, the heat insulating material for the pier is embedded in the frame concrete so that the metal protective plate of the vacuum heat insulating material is flush with the frame concrete, and the pier for the base is placed on the metal protective plate. Since it is fixed by an adhesive or the like, the indoor space is not narrowed even if the thickness of the pier is not reduced by the thickness of the pierce heat insulating material.

  In addition, since spray insulation work will be performed after fixing the pier, spray insulation (rigid urethane foam) cannot be installed directly under the pier, but between the pier and the reinforced concrete, rigid urethane foam In addition, since the vacuum heat insulating material having a much higher heat insulating performance is arranged, the heat insulating effect more than the spray heat insulating material layer formed on both sides of the pier is exhibited. In addition, since the spray heat insulating material layer having a thickness required by the spray heat insulation work can be formed on the protrusion with the nail hole, the protrusion with the nail hole does not cause a heat bridge.

  In particular, a metal protective plate that is difficult for screws and nails to pass through is placed between the pier and the vacuum heat insulating material. Therefore, when fixing a building interior member to the pier with a screw or a nail, inadvertently, Or, there is no risk of driving nails into the vacuum heat insulating material, the heat insulating effect inherent to the vacuum heat insulating material can be surely exhibited, and local deterioration of the heat insulating performance due to the small area occupied by the pier can be reliably avoided. is there.

  According to invention of Claim 5, in addition to said effect, a vacuum heat insulating material is accommodated in the metal rectangular tube case with a rectangular cross section, and the surface side board part of a square tube case is made of the metal of a vacuum heat insulating material. Since it is a heat insulating material for piers made of a protective plate, there is no need to bond a vacuum heat insulating material to a metal protective plate, and there is an effect that it is easy to manufacture the heat insulating material for piers.

  According to the sixth aspect of the present invention, in addition to the above-described effect, by fixing the L-shaped bracket to the cap nut with screws, the pier is arranged between the rising pieces of the opposing L-shaped bracket, and the bolt and nut Since it can be fixed with an adhesive, there is no need to use an adhesive on site.

  According to the invention described in claim 7, since the spray insulation work is performed after the base heat insulating pier is bonded to the surface of the concrete frame, the spray heat insulating material cannot be constructed directly under the pier. Since a vacuum heat insulating material that has a much higher heat insulating performance than the spray heat insulating material is arranged between the two, the heat insulating effect more than the spray heat insulating material layer formed on both sides of the pier is demonstrated. Become.

Moreover, since a metal protective plate that is difficult for screws and nails to pass through is placed between the pier and the vacuum heat insulating material, when fixing the building interior member to the pier with screws or nails, accidentally, screws or There is no risk of driving nails into the vacuum insulation material, the heat insulation effect inherent to the vacuum insulation material can be reliably exerted, and local deterioration of the insulation performance due to the small area occupied by the pier can be reliably avoided. .

  According to the eighth aspect of the present invention, the heat insulating material for the pier is embedded in the frame concrete so that the metal protective plate of the vacuum heat insulating material is flush with the frame concrete, and the pier for the base is placed on the metal protective plate. Since it is fixed by an adhesive or the like, the indoor space is not narrowed even if the thickness of the pier is not reduced by the thickness of the pierce heat insulating material.

  In addition, after fixing the base pier to the metal protective plate of the pier thermal insulation embedded in the concrete with adhesive, etc., the spray insulation work will be performed, so the spray thermal insulation directly under the pier However, the vacuum insulation material, which has far higher insulation performance than the spray insulation material, is placed between the pier and the frame concrete, so it is more than the spray insulation layer formed on both sides of the pier. The heat insulation effect is exhibited. In addition, since the spray heat insulating material layer having a thickness required by the spray heat insulation work can be formed on the protrusion with the nail hole, the protrusion with the nail hole does not cause a heat bridge.

  In particular, a metal protective plate that is difficult for screws and nails to pass through is placed between the pier and the vacuum heat insulating material. Therefore, when fixing a building interior member to the pier with a screw or a nail, inadvertently, Or, there is no risk that nails will be driven into the vacuum heat insulating material 2, the original heat insulating effect of the vacuum heat insulating material 2 can be surely exhibited, and the local deterioration of the heat insulating performance due to the small area occupied by the pier is surely avoided. To get.

  According to the ninth aspect of the present invention, in addition to the above-described effects, a crosspiece is arranged between the rising pieces of the L-shaped bracket screwed to the cap nut and fixed with bolts and nuts. There is an effect that it is not necessary to use. In addition, even though the crosspiece is fixed to the L-shaped bracket secured to the cap nut with bolts and nuts, a heat insulation sheet is interposed between the cap nut and the L-shaped bracket, so the L-shaped bracket is heated. Does not cause bridging.

  FIG. 1 shows a base heat insulating pier A according to the present invention, and FIG. 2 shows a heat insulating structure of the pier 1 using the base heat insulating pier A. The base heat insulating pier A prevents damage to the vacuum heat insulating material 2 due to screws or nails 3 driven into the pier 1 between the base pier 1 and the vacuum heat insulating material 2 disposed on the back surface thereof. This is a composite material provided with a metal protection plate 4 for the purpose.

  As the pier 1 for the foundation, in many cases, a solid material (square material) having an appropriate thickness, for example, a thickness of about 20 to 30 mm (preferably about 20 mm) and a width of about 30 to 60 mm (preferably about 50 mm) is used. Although it is used, the material is not limited to a solid material as long as screws and nails 3 are effective, and may be a woody material such as a laminated material, an LVL single plate laminated material, or a plywood. The metal protection plate 4 may be a metal having a hardness that is difficult for screws and nails to penetrate, and may be an iron plate, a steel plate, or the like, but is preferably a stainless steel plate because there is no risk of rusting. The thickness of the metal protection plate 4 is preferably about 2 mm, although it depends on the material. This is because if it is too thin, the screw or the nail 3 can easily penetrate, and if it is too thick, the weight increases, which is uneconomical.

  The vacuum heat insulating material 2 is a heat insulating material having a known structure in which the inside of a sealed container formed of a gas barrier film such as a resin film or aluminum foil is decompressed, and setting it to a thickness of about 5 mm is comparable to a hard urethane foam of 50 mm. It is preferable at the point which can ensure the heat insulation performance to do.

  As shown in FIG. 1, the base heat insulating pier A is bonded to the surface of the skeleton concrete 5 with the pier 1 facing outward, and then, as shown in FIG. 2, the reinforced concrete 5 The surface of the pier 1 is formed with a surface of the pier 1 exposed from the blast insulator layer, and the interior of the pier 1 is a building interior. The structural member is fixed with screws or nails 3 to form a heat insulating structure of the pier 1. As a member for building interior, for example, various members such as a wooden shaft for a gypsum board (trunk edge and studs), a sash and curtain box arranged around the sash are used. 7 is a wooden shaft 8 to which 7 is attached.

  According to the above configuration, the spray insulation material (hard urethane foam) 6 cannot be constructed directly below the pier 1 because the spray insulation work is performed after the base insulation pier A is bonded to the surface of the frame concrete 5. Between the pier 1 and the frame concrete 5, the vacuum heat insulating material 2 having a much higher heat insulating performance than that of the rigid urethane foam is disposed. A heat insulation effect will be exhibited.

  Moreover, since a metal protective plate 4 that is difficult for the screws and nails 3 to pass through is disposed between the pier 1 and the vacuum heat insulating material 2, when the building interior member is fixed to the pier 1 with screws or nails 3. There is no risk of inadvertently driving the screw or nail 3 to the vacuum heat insulating material 2, the heat insulating effect inherent to the vacuum heat insulating material 2 can be surely exhibited, and the local heat insulating performance due to the small area occupied by the pier 1 It is possible to surely avoid the decrease in the above.

FIG. 3 shows another embodiment of the base heat insulating pier A according to the present invention, and FIG. 4 shows the heat insulating structure of the pier 1 using the base heat insulating pier A. In this embodiment, the base heat insulating pier A is substantially perpendicular to the back surface side on both sides of the metal protection plate 4 provided between the base pier 1 and the vacuum heat insulating material 2 disposed on the back surface thereof. It is characterized in that the support plate 9 including the bent first plate portion 9a and the second plate portion 9b with a nail hole turned substantially perpendicularly from the front end thereof is bent and connected.

  According to the above configuration, even if an external force acting in the direction of pressing the pier 1 against the surface of the frame concrete 5 acts on the ground insulation pier A for some reason, the first plate portion 9a of the support plate 9 moves to the frame concrete 5. Therefore, the load applied to the pier 1 can be supported by the support plate 9, so that the vacuum heat insulating material 2 is not crushed and the thickness of the vacuum heat insulating material 2 can be kept constant.

  When the surface of the concrete frame 5 is a vertical surface such as a wall surface or a beam side surface, the second plate portion 9b of the support plate 9 is made of the concrete nail 10 with the concrete nails 10 as shown by phantom lines in FIGS. By fixing to the surface of 5, even if a tensile force acts on the base heat insulating pier A, there is no possibility that the base heat insulating pier A is peeled off from the concrete frame 5.

  Therefore, it is suitable when the building interior member fixed to the pier 1 with screws or nails 3 is a curtain box in which a tensile force acts every time the curtain is opened and closed. The support plate 9 may be provided continuously over the entire length of both sides of the metal protection plate 4, or may be provided locally at intervals in the longitudinal direction of both sides of the metal protection plate 4. Since other configurations and operations are the same as those of the embodiment of FIGS. 1 and 2, the same components are denoted by the same reference numerals and description thereof is omitted.

  FIG. 5 shows another embodiment of the base heat insulating pier A according to the present invention, and FIG. 6 shows the heat insulating structure of the pier 1 using the base heat insulating pier A. In the base heat insulating pier A in this embodiment, the metal protection plate 4 is formed by the surface side plate portion 40a of the rectangular metal case 40 having a rectangular cross section in which the vacuum heat insulating material 2 is accommodated. Projecting pieces 11 with nail holes projecting flush with the back side plate part 40b are connected to both sides of the back side plate part 40b.

  According to the above configuration, since the vacuum heat insulating material 2 is accommodated in the rectangular metal case 40 having a rectangular cross section, the pier 1 is pressed against the surface of the frame concrete 5 against the base heat insulating pier A for some reason. Even if an external force is applied in the direction, the force is transmitted from the rectangular tubular case 40 to the frame concrete 5, and the load applied to the pier 1 can be supported by the rectangular cylindrical case 40. The heat insulating material 2 is not crushed, and the thickness of the vacuum heat insulating material 2 can be kept constant.

  Further, since the front side plate portion 40a of the metal square tube case 40 functions as a metal protection plate 4 for preventing the vacuum heat insulating material 2 from being damaged by the screws or nails 3 driven into the pier 1, When fixing the structural member to the pier 1 with screws or nails 3, there is no risk of inadvertently driving the screws or nails 3 up to the vacuum heat insulating material 2, and the heat insulating effect inherent to the vacuum heat insulating material 2 can be reliably exhibited. Therefore, it is possible to reliably avoid local deterioration of the heat insulation performance due to the small area occupied by the pier 1.

  Moreover, since the projecting pieces 11 with nail holes projecting flush with the back surface side plate portion 40b are provided on both sides of the back surface side plate portion 40b of the rectangular tube-shaped case 40, the surface of the concrete frame 5 is a wall surface. In the case of a vertical surface such as a beam side, as shown by phantom lines in FIGS. Even if a tensile force is applied to the heat insulating pier A, there is no possibility that the base heat insulating pier A is peeled off from the frame concrete 5.

Therefore, it is suitable when the building interior member fixed to the pier 1 with screws or nails 3 is a curtain box in which a tensile force acts every time the curtain is opened and closed. A plurality of projections 11 with nail holes are provided on both sides of the back side plate portion 40b of the rectangular tube case 40 at appropriate intervals in the longitudinal direction, but are provided continuously over the entire length of both sides of the back side plate portion 40b. May be. Since other configurations and operations are the same as those of the embodiment of FIGS. 1 and 2, the same components are denoted by the same reference numerals and description thereof is omitted.

  FIG. 7 shows a heat insulating material B for piers according to the present invention, and FIGS. 8 to 12 show a heat insulating structure of the pier 1 constructed using the heat insulating material B for piers. The heat insulating material B for piers includes a vacuum heat insulating material 2 and a metal protective plate 4 that covers the surface of the heat insulating material B. The metal protective plate 4 has a plurality of nail holes protruding in a flush manner on both sides thereof. The projecting piece 11 and a plurality of anchor projecting portions 12 projecting to the back surface side are provided in a row, and as shown in FIG. 10, the base pier 1 can be fixed on the metal protection plate 4 with an adhesive. As shown in FIG. 12, the metal protective plate 4 prevents the vacuum heat insulating material 2 from being damaged by the screws or nails 3 driven into the pier 1.

  In the illustrated example, the anchor protrusion 12 is composed of a plate portion bent at a right angle from both sides of the metal protective plate 4 to a back surface side and a plate portion folded at a right angle from the tip. The shape and structure of the anchor protrusion 12 can be appropriately changed. The metal protection plate 4 and the vacuum heat insulating material 2 are fixed to each other by an adhesive, but instead of the adhesive, the both sides of the vacuum heat insulating material 2 are sandwiched and fixed by the anchor protrusions 12, By folding a part of the anchor protrusion 12 to the back side of the vacuum heat insulating material 2 and sandwiching the vacuum heat insulating material 2 between the bent portion and the metal protective plate 4, the metal protective plate 4 and the vacuum heat insulating material are sandwiched. The material 2 may be integrated.

  The heat insulation structure of the pier 1 constructed using the above pierce heat insulating material B and its construction procedure will be described as follows. First, as shown in FIG. 8, the heat insulating material B for the timber is fixed to the inner surface of the formwork 13 for placing the concrete with a stopper 14 such as a nail or a screw driven into the protruding piece 11 with a nail hole.

  In this state, the concrete is placed in the mold 13, cured and cured, and then removed from the mold. As shown in FIG. 9, the insulation material B for the pier is placed on the frame concrete 5, and the metal protection plate 4 is mounted on the frame concrete. 5 is embedded in a state of being flush with the surface of 5. As shown in the figure, it is desirable to cut off the tip of the fastener 14.

  Next, as shown in FIG. 10, after fixing the base pier 1 on the metal protective plate 4 with an adhesive, as shown in FIG. A spraying heat insulating material layer having a thickness of about 25 mm by the spraying heat insulating material (hard urethane foam) 6 is formed in a state where the surface of the pier 1 is exposed from the spraying heat insulating material layer.

  After that, as shown in FIG. 12, the building interior member is fixed to the pier 1 with screws or nails 3 to complete the heat insulating structure of the pier 1. As the building interior member, for example, various members such as a wooden shaft (a trunk edge and a stud) for gypsum board, a siding board and a curtain box arranged around the sash are used.

  According to the above configuration, the heat insulating material B for the pier is embedded in the frame concrete 5 so that the metal protective plate 4 of the vacuum heat insulating material 2 is flush with the frame concrete 5, and the metal protective plate 4 is used for the foundation. Since the pier 1 is fixed by an adhesive, the indoor space is not narrowed even if the thickness of the pier 1 is not reduced by the thickness of the heat insulator B for the pier.

After fixing the base pier 1 with the adhesive to the metal protection plate 4 of the pier heat insulation B embedded in the frame concrete 5, the spray insulation work is performed immediately below the pier 1 (see FIG. Hard urethane foam) 6 cannot be constructed, but vacuum insulation 2 having a much higher thermal insulation performance than rigid urethane foam is placed between the pier 1 and the frame concrete 5, so it is formed on both sides of the pier 1 The heat insulation effect more than the sprayed heat insulating material layer made will be exhibited. Also,
Since the spray insulating material layer having a thickness required by the spray insulation work can be formed on the projection 11 with the nail hole, the projection 11 with the nail hole does not cause a heat bridge.
