The heat insulating board material installation member 10 includes a film part 11 made of a belt-like sheet, a plate part 12 joined to the long side of the film part 11, and a side opposite to the side where the film part 11 of the plate part 12 is joined. , A bent portion 13 formed so as to be bent substantially perpendicular to the plate portion 12, a first packing portion 14 formed so as to protrude from the main surface of the plate portion 12, and a protruding portion from the bent portion 13. It is comprised from the 2nd packing part 15 formed in this way. In addition, although the film part 11 and the board part 12 are normally joined so that it may become substantially right angle, it does not necessarily need to be right angle.

The film part 11 is composed of a belt-like sheet, and its width is preferably slightly wider than the width of the contact part of the support frame when the film part 11 is brought into contact with the support frame. 80 mm is preferred. The length is preferably 1820 mm or more, for example, and the thickness is preferably 0.1 to 0.4 mm, for example. Such a thin sheet shape is because if the film portion 11 is thick, the height of the floorboard, wallboard, etc. placed on the film portion 11 will be different from the design dimensions, which may hinder the construction. It is. The material of the film part 11 is not particularly limited as long as it has a relatively high strength in a film state, and examples thereof include resins such as polyethylene and polypropylene.

Further, the length of the plate portion 82 is desirably the same as the length of the film portion 81.

Next, the construction method of the building using this heat insulation board member installation member 80 will be described.
FIG. 7 is a cross-sectional view schematically showing a construction method for a building using the heat insulation board material installation member 80, and shows a construction method for installing a heat insulation board material between the pillars of the wall.

As shown in FIG. 7, in the construction method of the present invention, first, the film portion 81 contacts the inner side surface 92a of the pillar 92 facing the building, and the plate portion 82 is placed on the surfaces 92b and 92c adjacent to the inner side surface 92a. The heat insulating board member installation member 80 is disposed on the plurality of pillars 92 so that they come into contact with each other. In order to firmly fix the film part 81, it is fixed using a nail or an adhesive.

Next, a heat insulating board material 91 having a trapezoidal cross section is inserted and fixed between the pillars 92 on which the heat insulating board material installation member 80 is disposed, and finally the wall plate 93 is installed.
At this time, since the first packing portion 83 made of a soft resin is in close contact with the side surface of the heat insulating board material 91 so as to prevent a gap air from entering, it is possible to sufficiently ensure the heat insulating property and the air tightness of the construction portion. .

Moreover, in this heat insulation board material installation member 80, since the escape recessed part 86 for accommodating the 1st packing part 83 is formed in the trapezoid-shaped board part 82, the heat insulation board material installation member shown in FIG. As in the case of 600, when the first packing portion 83 is pushed by the heat insulating board material, the first packing portion 83 can escape and enter the concave portion 86, and the heat insulating board material installation member 80 is disposed. When a heat insulating board material having a trapezoidal cross-sectional view is inserted between the frame bodies, the heat insulating board material and the heat insulating board material having a dimension such that there is no gap between the heat insulating board material and the heat insulating board material installation member 80, and The heat insulation board material can be effectively installed up to a heat insulation board material having a dimension such that the space between the heat insulation board material installation member 600 is the width of the packing part before insertion (l _{3 in} FIG. 6B). Variation in processing dimensions , Variation in dimension between the support frame body, tolerance for contraction of the support frame or insulation board material becomes wide as 0～2L ₃ at maximum.

In order to keep the pressing force of the first packing part 83 sufficiently when pressed by the heat insulating board material, the capacity of the escape recess 86 is preferably smaller than the capacity of the first packing part 83. For example, the depth is preferably 1 to 2 mm.

Further, since the cross-sectional shape of the plate portion 82 is trapezoidal, the first packing portion 83 acts so as to push out the heat-insulating board material having a trapezoidal shape in cross-sectional view (so as to push out toward the wall plate 93). It is possible to prevent a gap from being generated between the floor board and the wall board arranged in the vicinity thereof, and it is possible to prevent condensation or decay of the heat insulating board material or the like. As a result, there is no need to attach a sheet for preventing condensation to the heat insulating board material or the like as in the prior art.
