Description

  The present invention relates to a heat insulating structure that reduces heat transfer between the inside and outside of a steel frame combined reinforced concrete wall-type structure building.

  The heat insulating structure of a building is excellent in the energy saving effect of the building, and has recently been applied to a building such as a house. Insulation of a building needs to suppress heat transfer such as heat conduction, heat radiation, and heat convection between the inside and outside of the building as much as possible, so that the entire outdoor side of the building is covered with heat insulating material. The outer insulation structure to be constructed and the inner insulation structure to be constructed so as to cover the entire indoor side of the building with a heat insulating material have been proposed.

  Such a structure that covers the entire building with the heat insulating material can suppress the heat transfer between the inside and the outside, improve the efficiency of air conditioning and heating, and increase the energy saving effect. For example, in Patent Document 1, a heat insulating material is also used on the inside and outside of a reinforced concrete wall using a heat insulating material that also serves as a formwork, and the outer peripheral portion of the reinforced concrete structure is insulated by placing a heat insulating roof plate. Points are listed.

  However, it may be structurally difficult to cover the entire building with a heat insulating material without a gap. For example, in reinforced concrete structures and steel structures, structures that protrude outward, such as balconies, fences, parapets, and outer corridors, are often constructed, and the thermal insulation effect is reduced by the thermal bridge phenomenon that causes heat transfer through such protruding structures. become. In addition, since a mounting portion such as a window frame cannot be covered with a heat insulating material, a thermal bridge phenomenon is likely to occur and the heat insulating effect is reduced.

  For such a thermal bridge phenomenon, for example, in Patent Document 2, an outer heat insulating forming tool configured by inserting an upper end support bar and a lower end support member that form a through hole in a heat insulating plate to support a protruding structure is disclosed. Have been described. Further, Patent Document 3 describes that a projecting structure is constructed by constructing a double wall for exterior by a double beam provided in parallel with a frame beam with a heat insulating layer sandwiched between outer wall surfaces of the frame. Moreover, in patent document 4, the point which improved the heat insulation of the whole building by covering the whole parapet with a heat insulating material is described.

JP 2007-162252 A Japanese Patent No. 3958335 Japanese Patent No. 4025910 Japanese Patent No. 4198141

  The above-mentioned thermal bridge phenomenon is a phenomenon in which heat moves between the outside and the inside through a member having good thermal conductivity. However, since the above-described protruding structure is exposed to the outside, there is a difference between the protruding structure and the internal structure. When heat transfer occurs between them, it is inevitable that the heat insulation effect between the outside and inside of the building is reduced.

  In Patent Document 2, although a heat insulating plate is provided between the protruding structure and the heat insulating effect is enhanced, a thermal bridge phenomenon occurs through the upper end supporting bars and the lower end supporting material, and the heat insulating effect is reduced accordingly. Moreover, in patent document 3, although the heat insulation effect is acquired, the cost burden for constructing a double beam must be large. In Patent Document 4, although the thermal bridge phenomenon through the parapet can be surely prevented, the external design of the parapet is restricted because it is covered with the heat insulating material, and the consumption of the heat insulating material increases, and the cost burden increases accordingly.

  Therefore, an object of the present invention is to provide a heat insulating structure for a steel frame combined reinforced concrete wall type structure capable of suppressing such a thermal bridge phenomenon and exhibiting a sufficient energy saving effect.

  The heat insulating structure of the steel-framed reinforced concrete wall structure building according to the present invention includes a foundation part in which heat insulating material is provided in layers on both sides of the foundation concrete and a soil part in which the heat insulating material is laid so as to cover the lower surface of the soil concrete. An underfloor structure, an outer wall structure in which a heat insulating material is disposed so as to cover at least the outer surface of the reinforced concrete, a roof structure in which a heat insulating material is laid so as to cover the roof surface, and a slab structure that is connected to the outer wall structure. And a steel frame combined reinforced concrete wall structure with a steel structure that supports the roof structure, wherein the member attached to the outer wall structure or the roof structure is made of a long fiber reinforced curable resin foam. It is characterized by being attached via a member. Furthermore, the attachment member is closely fixed between the heat insulating materials on the outer wall structure, and an exterior material is attached to the attachment member via an attachment fitting. Furthermore, a window frame is attached to the outer wall structure via the attachment member. Furthermore, it has a parapet structure projecting around the roof structure, and the parapet structure is attached to a plurality of support members fixed to the roof structure via long fiber reinforced curable resin foam. And the heat insulating material is arrange | positioned between the said roof structures. Furthermore, the parapet structure includes a frame member fixed to the support member and an exterior material attached so as to cover the frame member.

  By having the above configuration, a thermal bridge phenomenon occurs in a long fiber reinforced curable resin foam having mechanical strength comparable to that of wood used for wood structure materials and lower thermal conductivity than wood. Since it is provided at the location, it is possible to suppress the thermal bridge phenomenon and enhance the heat insulation effect.

  That is, since the member attached to the outer wall structure or the rooftop structure is attached via an attachment member made of a long fiber reinforced curable resin foam, the thermal fiber phenomenon that tends to occur in the attachment portion is caused by the long fiber reinforced curable resin foam. It becomes possible to suppress by the attachment member which consists of a body.

  In the outer wall structure, a thermal bridge phenomenon occurs through the mounting member that holds the heat shield sheet and the exterior material. However, if the mounting member is made of a long fiber reinforced curable resin foam, the heat insulating effect can be further enhanced. In addition, a thermal bridge phenomenon occurs when the metal frame member of the window frame comes into contact with the wooden structure member of the wall structure in the mounting portion of the window frame. If an attachment member made of a resin foam is provided and the window frame is attached, the attachment member acts so that the thermal bridge phenomenon is blocked and the heat insulation effect is enhanced.

  In addition, in the rooftop structure, a thermal bridge phenomenon occurs through the surrounding parapet structure, but multiple mounting members that support the parapet structure on the rooftop structure are fixed via long fiber reinforced curable resin foam. And if a heat insulating material is arrange | positioned between a rooftop structure and a parapet structure, it will act so that the thermal bridge phenomenon between a parapet structure and a rooftop structure may be interrupted | blocked, and the heat insulation effect will increase.

  As described above, by installing a mounting member made of long fiber reinforced curable resin foam with high mechanical strength and low thermal conductivity on the mounting part that cannot be covered with a heat insulating material, the thermal bridge phenomenon is blocked. Further, the heat insulating effect by the heat insulating material can be further improved, and an excellent energy saving effect can be exhibited.

The embodiments described below are preferable specific examples for carrying out the present invention, and thus various technical limitations are made. However, the present invention is particularly limited in the following description. Unless otherwise specified, the present invention is not limited to these forms.

  FIG. 1 is a schematic configuration diagram relating to an embodiment of the present invention. The steel frame combined reinforced concrete wall structure shown in FIG. 1 includes an underfloor structure 1 formed by placing concrete on the ground, a floor structure 2 constructed on the upper portion of the underfloor structure 1, and an upper portion of the underfloor structure 1.

  In the underfloor structure 1, foundation concrete 10 and soil concrete 11 made of reinforced concrete are formed on the ground by a known construction method. A plurality of formwork unit panels 12 are arranged on both sides of the foundation concrete 10 without gaps and joined. The formwork unit panel 12 is a plate-shaped heat insulating material made of a foamed synthetic resin material, and is used as a formwork when placing concrete. After the foundation concrete 10 is formed, the formwork unit panel 12 is joined as it is on both sides. Used as a heat insulating structure.

  As the foamed synthetic resin material used as the heat insulating material, a known material may be used, and examples thereof include polystyrene foam, polypropylene foam, polyethylene foam, polyurethane foam, phenol foam, and acrylic foam. Moreover, a nonflammable inorganic foam material can also be used. Polystyrene foam is preferable from the viewpoints of heat insulation and processability.

  Further, a plate-like heat insulating material 13 is laid on the lower surface of the interstitial concrete 11 without any gap, and heat transfer between the outside and the inside of the underfloor structure 1 by covering the foundation concrete 10 and the interstitial concrete 11 with the heat insulating material. Suppresses the heat insulation effect.

  The floor structure 2 is supported by a steel floor bundle 20 erected on the soil concrete 11, and a large pull 21 is horizontally arranged on the large pull 21. And the floor board 23 is arranged and attached to the upper surface of the joist 22 in the shape of a plane. In the floor structure 2, since the heat insulating material is provided in the underfloor structure 1, the heat insulating material is not provided.

  The outer wall structure 3 is constructed of a frame using known steel frames such as columns, beams, girders and braces, and a reinforced concrete wall 30 is formed along the outer wall surface. The reinforced concrete wall 30 is constructed by placing reinforcing bars by a known construction method and placing concrete. Similar to the underfloor structure 1, the formwork unit panels 31 are arranged on both sides of the reinforced concrete wall 30 so as to cover the entire surface. The formwork unit panel 31 is a plate-like heat insulating material made of a foamed synthetic resin material like the formwork unit panel 12, and is used as a formwork when placing concrete, and after the reinforced concrete wall 30 is formed. Is used as a heat insulating structure in a state where it is directly joined to both sides.

  An interior material 32 is attached to the inside of the outer wall structure 3 so as to cover the formwork unit panel 31, and a heat shield sheet 35 and an exterior material are provided on the outside of the outer wall structure 3 so as to cover the formwork unit panel 31. 33 is attached. A ventilation layer 34 is formed between the heat shield sheet 35 and the exterior material 33, and air is constantly circulated through the ventilation layer 34 to release moisture inside the mold unit panel 31 to the outside and the exterior material. 33 heat can be dissipated.

  FIG. 2 is a partially enlarged cross-sectional view along the vertical direction (FIG. 2A) and a partially enlarged cross-sectional view along the horizontal direction (FIG. 2B) regarding the holding structure of the exterior material 33 and the heat shield sheet 35. An attachment member 36 for holding the exterior material 33 and the heat shield sheet 35 is fixed between the formwork unit panels 31 which are heat insulating materials. A mounting bracket 37 is screwed to the mounting member 36. The mounting bracket 37 is a narrow plate-like body extending in the vertical direction of the outer wall structure, and is formed in a stepped shape by bending both side portions. The exterior material 33 is fixed and held on both side portions of the mounting bracket 37, and the heat shield sheet 35 is pressed and held between the mounting member 36 and the mounting bracket 37.

  As a material used for the attachment member 36, a material having high heat insulation and high mechanical strength is used, and a long fiber reinforced curable resin foam is preferable. The long fiber reinforced curable resin foam is formed by embedding a large number of inorganic or organic long fibers in a hard urethane resin or a hard polyester resin provided with foamability by aligning them in the length direction of the main yarn. It has similar mechanical strength and lower thermal conductivity than wood. For example, a thermosetting resin foam made of a hard urethane resin reinforced with long glass fibers (eg, FFU (registered trademark) manufactured by Sekisui Chemical Co., Ltd.) has a specific gravity and mechanical strength comparable to wood. And thermal conductivity is less than half that of wood. Therefore, by using such a material for the attachment member 36, the thermal bridge phenomenon that occurs through the structural material of the holding structure of the exterior material 33 can be suppressed.

  FIG. 3 is a plan view, a front view, and a side view relating to the attachment member 36. The attachment member 36 has a through hole 36a into which a fixing screw is inserted at the center, and the four side surfaces 36b of the attachment member 36 are curved so as to bulge.

The attachment member 36 is fitted into a gap formed between the formwork unit panels 31 and is fixed to the reinforced concrete wall 30 by a fixing screw 36c inserted into the through hole 36a. The side surface 36b of the mounting member 36 is pressed into contact with the formwork unit panel 31 to be deformed into a flat shape and is in close contact with no gap.

  The through hole 36a is filled with a resin material, the mounting surface of the mounting bracket 37 of the mounting member 36 is formed in a flat shape, and the outer surfaces of the mounting member 36 and the formwork unit panel 31 are substantially flush. . The heat shield sheet 35 attached so as to cover the outer surface of the mounting member 36 and the formwork unit panel 31 is fixed to the mounting surface of the mounting member 36 with a fixing portion 37a at the center of the mounting bracket 37 by a fixing screw. It is held by. The holding portions 37b on both sides of the fixed portion 37a are formed to be bent in a stepped shape, and the exterior member 33 comes into contact with the mounting surface of the holding portion 37b and is held by screws. Since the holding portion 37 b of the mounting bracket 37 is formed in a stepped shape, a gap is formed between the exterior material 33 and the heat shield sheet 35 to form the ventilation layer 34.

  A part of the outer wall structure 3 has a rectangular opening and a known window frame 38 is attached thereto. A mounting member 39 is joined and fixed in a frame shape to the inner periphery of the opening, and the window frame 38 is mounted via the mounting member 39. The material used for the attachment member 39 is a long fiber reinforced curable resin foam similar to that of the attachment member 36. Therefore, the attachment member 39 has a specific gravity and mechanical strength comparable to that of wood, and conducts heat. The rate is less than half that of wood. By using such a material for the attachment member 39, it is possible to suppress the thermal bridge phenomenon that occurs from the window frame 38 through the structural material of the outer wall structure 3.

  FIG. 5 is a partially enlarged cross-sectional view of the attachment portion of the window frame 38. The attachment member 39 is fixed to the inner peripheral surface of the opening of the outer wall structure 3, and the metal frame member 38 a and the resin frame member 38 b of the window frame 38 are fixed to the attachment member 39 with screws or the like. Since the metal frame member 38a having a high thermal conductivity is fixed to the mounting member 39, the thermal bridge phenomenon is suppressed and the interior material 32 is in contact with the resin frame member 38b having a low thermal conductivity. The thermal bridge phenomenon through the interior material 32 is suppressed. Therefore, it is possible to enhance the heat insulation effect at the attachment portion of the window frame 38.

The attachment member 64 penetrates the insertion hole 31a and protrudes outward from the frame member. 60 is fixed to the protruding tip.

  Since the attachment member 64 is made of a long fiber reinforced curable resin foam, it is excellent in heat insulation and mechanical strength, and acts to suppress the movement of heat between the parapet structure 6 and the outer wall structure 3. . Moreover, since the attachment member 64 is joined to the insertion hole 31a of the formwork unit panel 31 of the outer wall structure 3 without a gap, it is possible to suppress the movement of heat through the joined portion and to improve the heat insulating effect. .
