Description

  The present invention relates to a heat insulating reinforcing member suitable for a portion that becomes a thermal bridge of a building, a heat insulating panel using the same, and a heat insulating structure using the heat insulating reinforcing member.

  Conventionally, in a steel structure building and a building using a steel frame, there is a problem that a thermal (cold) bridge is likely to occur because the thermal conductivity of iron is large. In particular, since a heat insulating material cannot be applied inside the groove of the lip groove type steel, there is a problem that the heat insulating performance is partially deteriorated and a thermal bridge is easily formed.

  Also, even if you want to ensure airtightness, heat insulation such as glass wool or foamed plastic does not have flexibility, so it will not be possible to fill the inside of the lip groove steel groove with heat insulation. There is a problem that airtightness cannot be maintained by entering.

  In order to solve such a problem, for example, Japanese Patent Laid-Open No. 5-179723 (Patent Document 1) discloses a film sheet-like synthetic resin material divided into a shape corresponding to the gap inside the gap of the shaft assembly. A wall body filled with a heat insulating material coated with is proposed.

  Japanese Patent Laid-Open No. 10-121649 (Patent Document 2) fills the inside of the grooved frame material by foaming urethane foam, and adheres the urethane foam to the grooved frame material with the adhesiveness associated with foam molding. What has been proposed. Japanese Patent Laid-Open No. 10-169030 (Patent Document 3) discloses that both lip portions facing each other across an opening of a lip groove type steel are bent toward the inner side of the steel material so as to have a cross-sectional shape, and the lip groove There has been proposed one in which a heat-insulating attachment member is press-fitted and attached through an opening of a steel mold.

A lip 2 a of the steel plate 2 is inserted, and a heat insulating material 5 (not shown) is bonded to the connecting portion 1 c of the heat insulating reinforcing member 1 protruding from the upper surface of the floor panel 10 with an adhesive tape 6. The heat insulation reinforcing member 1 of this embodiment is an example in which the connecting portion 1c protrudes in the width direction (left and right direction in FIG. 3).

  The heat insulation reinforcing member 1 shown in FIG. 2 (d) is an example divided into two at a substantially central portion along the axial direction of the grooved steel 2 (the direction from the front side of the paper to the back side of the paper in FIG. 2). In such a configuration, one of the heat insulating reinforcing members 1 divided into two along the axial direction of the grooved steel 2 is configured with the above-described foamed polyethylene foam-based heat insulating material, and the other is replaced with a foamed phenol foam-based heat insulating material. I can do it.

  The foamed phenol foam heat insulating material can be produced by a technique (Neoma Foam (registered trademark)) developed by the present applicant and disclosed in International Publication No. WO-00-1761. This phenolic resin foam is a high-performance phenolic foam corresponding to one type according to the standard of phenol foam heat insulating plate specified in JIS A9511, and has high heat insulation performance and little dimensional change due to heat. It can be preferably used as a material. In addition, the phenol resin foam can be preferably used in a portion where high combustion resistance is required because when the flame acts, the surface only carbonizes and does not spread suddenly and does not dissolve. .

Phenolic resin foam according to the above techniques, and the phenol resin base portion, density and a bubble portion formed from a large number of fine bubbles are phenol foam of ^{10kg / m 3 ~100kg / m 3} , the fine bubbles Hydrocarbon is contained and the average cell diameter is in the range of 5 μm to 200 μm, and the cell walls of most of the fine cells are composed of a smooth phenol resin substrate surface. And despite the fact that the blowing agent is a hydrocarbon, it has a thermal conductivity comparable to that of conventional chlorofluorocarbon-based blowing agents, and there is no change over time in the thermal conductivity, resulting in a mechanical strength such as compressive strength. Excellent and improved brittleness.

  The heat insulating property in the phenol resin foam can be ensured by keeping the average cell diameter as small as 5 μm to 200 μm, preferably as small as 10 μm to 150 μm, and keeping the closed cell ratio as high as 80% or more. In addition, the phenol resin foam has high combustion resistance, and when the flame acts, the surface is merely carbonized and does not spread suddenly and does not melt. Furthermore, no toxic gas is generated.

For example, when the density of the phenol resin foam is set to 27 kg / m ³ , the thermal conductivity at 20 ° C. is 0.020 W / m · K, the compressive strength is 15 N / cm ² , and the thermal deformation temperature is 200 ° C. It is. As for the performance of the above-mentioned phenol resin foam, three types of extruded foamed polystyrene have thermal conductivity: 0.028 W / m · K, compressive strength: 20 N / cm ² , heat deformation temperature: 80 ° C., rigid urethane foam Two types have sufficiently high performance as compared with thermal conductivity: 0.024 W / m · K, compressive strength: 8 N / cm ² , heat distortion temperature: 100 ° C.

  For this reason, in the heat insulation reinforcement member 1 which consists of a phenol resin foam, it is possible to exhibit substantially the same heat insulation performance and combustion resistance performance with a thickness of about 2/3 that of conventional extruded polystyrene and rigid urethane foam. is there.

The opening 3 communicating with the outside air can be easily communicated with a part of the outside by using the heat insulating reinforcing member 1.

  Further, the fitting portion 1a of the heat insulating reinforcing member 1 is fitted into the groove interior 4 of a pair of grooved steel 2 having a lip 2a formed on at least one side of the opening portion 3 in the direction of closing the opening portion 3, and A heat insulating panel B in which the lip 2a of the grooved steel 2 is inserted into the constricted portion 1b of the heat insulating reinforcing member 1 and the connecting portions 1c of the heat insulating reinforcing member 1 are respectively connected to both ends of the heat insulating material 5 by connecting members is easily created. I can do it.

  Further, the constricted portion of the heat-insulating reinforcement member 1 has a lip 2a formed on at least one side of the opening 3 toward the direction of closing the opening 3 and the groove inside 4 of the grooved steel 2 constituting a part of the building. 1b is inserted and the lip 2a of the grooved steel 2 is inserted into the constricted portion 1b of the heat insulation reinforcing member 1, and the connecting portion 1c of the heat insulation reinforcing member 1 is attached to the end of the heat insulating material 5 by the adhesive tape 6 serving as a connecting member. The connected heat insulating structure A can be easily constructed.

  As an application example of the present invention, the present invention can be applied to a heat insulating reinforcing member suitable for a portion that becomes a thermal bridge of a building, a heat insulating panel using the heat insulating reinforcing member, and a heat insulating structure using the heat insulating reinforcing member.
