Description

Description: TECHNICAL FIELD The present invention relates to a heat insulating panel used as a floor panel or the like of a building, and more specifically, a heat insulating material is optimal for a panel frame body (framework frame body). The present invention relates to a technique for filling in a state.

[Conventional technology]

As is well known, various techniques have been proposed for improving the heat insulating property of a wall portion such as a floor panel in a building. As an example, there is a technique as shown in FIG. In this technique, a heat insulation receiving net 51 is stretched over the floor joists 50 ... 50, heat insulating materials 52, 52 are inserted between the floor joists 50 ... 50, and the heat insulating materials 52, 52 are aforesaid. It is supported from below by a net 51.

Further, as another example, as shown in FIG. 9, a heat insulating material 54 ... 54 is inserted between the aggregates 53 ..
Moreover, the face materials 55, 5 are provided above and below the heat insulating materials 54 ... 54, respectively.
5 is fixed.

[Problems to be Solved by the Invention]

However, since the construction shown in FIG. 8 is unavoidable for construction on site, it is not possible to perform precise work. Therefore, the heat insulating material 52 between the floor joists 50 ... However, there is a problem that it is impossible to reliably and completely fill the holes 52. Further, in the structure shown in FIG. 9 above, since the heat insulating materials 54 ... 54 are simply inserted without any means between the respective aggregates 53 ..
A gap is formed between the heat insulating material 54 and the heat insulating material 54, which causes a problem that not only the heat insulating property is deteriorated but also dew condensation is caused.

Further, in both of the above cases, if sufficient quality control is performed, the heat insulating material can be satisfactorily filled. However, quality control for this purpose requires a great deal of cost, and the cost is reduced. It is a big hindrance to the above.

The present invention has been made in view of the above circumstances, and ensures that a heat insulating material is reliably filled between the aggregates of the panel frame body (framework frame body) in a panel manufacturing factory without any on-site construction. It is a technical subject to improve the heat insulating property and reduce the cost.

[Means for Solving the Problems]

Where as a specific means for achieving the above technical problem, a frame structure is formed from a plurality of vertical aggregates and horizontal aggregates,
A heat insulating panel comprising a frame member fixed to at least one surface in the thickness direction of the frame member, and a heat insulating member fitted in a space between the frame members of the frame member. A groove portion is formed on one side edge in the thickness direction of the contact surface of the heat insulating material with the heat insulating material, and the groove portion is formed on one side edge of the contact surface of the heat insulating material with each aggregate in the thickness direction. A convex part to be joined is formed, and the abutting surface of the heat insulating material to each aggregate is a taper surface with a reduced width on the other side in the thickness direction, and a notch groove is formed in the taper surface adjacent to the convex part. Along with the formation, the heat insulating material is being sandwiched and pressure-bonded between the aggregates with the abutting surface being crushed.

[Action]

According to the above means, when the heat insulating material is fitted into the space between the aggregates of the frame frame body that is firmly assembled, each bone is made so that the contact portion of the heat insulating material to each aggregate is crushed. Since it is configured to be sandwiched and crimped between the materials, in detail, the heat insulating material is manufactured to be slightly larger than the space between the aggregates, and the heat insulating material is forcibly inserted into the space. Since the heat insulating material is crushed, no space is formed between the heat insulating material and each aggregate, which improves the heat insulating property and prevents the occurrence of problems such as dew condensation. Furthermore, since the work of sandwiching and crimping the heat insulating material between the respective aggregates of the frame structure as described above can be performed in the factory, the heat insulating panel can be mass-produced and the cost can be reduced. It is also possible to improve the workability on site. Further, since the abutting surface of the heat insulating material is a tapered surface having a reduced width on the other side in the thickness direction, proper fitting can be performed without requiring high processing accuracy when manufacturing the heat insulating material.

Further, in addition to the above configuration, while forming a groove portion on the side edge on one side in the thickness direction of the contact surface with the heat insulating material in the aggregate,
Corresponding to this, a convex portion is formed on the side edge on one side in the thickness direction of the heat insulating material, and the groove portion and the convex portion are configured to engage with each other. At the time of fitting, the convex portion abuts and engages with the groove portion and plays a role of a so-called stopper. It is easily fitted at a predetermined position without excessively fitting and the other side in the thickness direction of the heat insulating material protruding from the frame. Can be fitted to. Then, a notch groove is formed in a portion of the heat insulating material adjacent to the convex portion of the tapered surface, and the end portion on one side in the thickness direction of the tapered surface is not in contact with the convex portion and is not integrated. The taper surface, that is, the contact surface, is easily deformed into a crushed state at the time of fitting.
