As shown in FIG. 10 , the packing heat insulating material 7 has a flat plate shape elongated along the longitudinal direction A and is configured to be housed in the heat insulating material housing portion 6 . The packing heat insulating material 7 is a foamed resin heat insulating material, and for example, a known material such as plate-like polyethylene foam, polystyrene foam, or urethane foam can be used. The packing heat insulating material 7 is fixed by bonding the lower surface 7c to the upper surface portion 3b1 with an adhesive, a double-sided tape, or the like. A plurality of grooves 7c1 arranged at predetermined intervals along the longitudinal direction A are formed in the lower surface 7c of the packing heat insulating material 7. As shown in FIG. These grooves 7c1 extend along the width direction B. As shown in FIG. Further, the groove 7c1 is formed in a shape that allows the reinforcing rib 6b to be just fitted. That is, the groove 7c1 is formed deeper at both ends in the width direction B than at the central portion. Since the central portion of the groove 7c1 in the width direction B is shallower than both ends in this way, it is possible to suppress the packing heat insulating material 7 from bending at the groove 7c1 portion. Therefore, the packing heat insulating material 7 becomes easy to handle. The depth of both ends of the groove 7c1 in the width direction B is smaller than the thickness of the packing heat insulating material 7 (thickness in the vertical direction C). Thereby, the side surface of the packing heat insulating material 7 in the width direction B is not divided in the longitudinal direction A by the groove 7c1. That is, when the packing heat insulating material 7 is accommodated in the heat insulating material accommodating portion 6, the heat insulating line is not cut off at the side surface 21f.

At one end (left end in FIG. 10) of the packing heat insulating material 7 in the longitudinal direction A, a fourth connecting protrusion 7a is formed to protrude leftward along the longitudinal direction A.

The fourth connecting convex portion 7a of the other packing heat insulating material 7 (on the right side in the figure) is fitted into the connecting fourth concave portion 7b of the packing heat insulating material 7, and the packing heat insulating materials 7 are also connected to each other.

As shown in FIGS. 4 and 7, the lower surface 3c of the dovetail barb portion 3 is formed with a mounting groove 3c1 which is disposed closer to the packing body 2 in the width direction B and extends along the longitudinal direction A. ing. As shown in FIG. 2, the mounting groove 3c1 is arranged at a position where it can face the upper surface of the outer peripheral foundation 104 in the vertical direction C when the basic packing 1 is arranged on the outer peripheral foundation 104. As shown in FIG. A long belt-shaped seal member 8 is arranged along the longitudinal direction A in the mounting groove 3c1. That is, the lower surface 3c of the dovetail barb portion 3 is provided with the seal member 8 extending along the longitudinal direction A near the packing body 2. As shown in FIG.

As shown in FIG. 7, the sealing member 8 is composed of, for example, a flat base portion 8a made of synthetic resin and elongated in the longitudinal direction A, and a sealing portion 8b formed on the lower surface 8a1 of the base portion 8a. ing. The sealing member 8 is arranged so that the lower surface 8b1 of the sealing portion 8b protrudes downward from the lower surface 3c of the dovetail barb portion 3, and the upper surface 8a2 of the base portion 8a is attached to the bottom surface of the mounting groove 3c1 with adhesive, double-sided tape, or the like. glued and fixed. The seal portion 8b in the present embodiment is a gel-like body made of a material that is gel-like at room temperature and has a thermoplastic resin as one main component. As used herein, the term "gel-like" means a gel-like state. Moreover, the term "gel" means "a solidified state having a structure in which colloidal particles or macromolecular solutes lose their independent motility due to interactions and are aggregated". In addition, the sealing portion 8b does not have to be particularly gel-like as long as it has either flexibility or elasticity. That is, the sealing portion 8b may be made of rubber, foamed resin, or the like. Alternatively, the sealing member 8 may be composed of only the sealing portion 8b without the base portion 8a.

Moreover, in the width direction B, the width of the mounting groove 3c1 is slightly larger than the width of the seal member 8. As shown in FIG. As a result, the gap in the width direction B between the seal member 8 and the mounting groove 3c1 serves as a clearance for the seal portion 8b of the seal member 8 when the base packing 1 is arranged on the outer periphery foundation 104. As shown in FIG. Therefore, it is possible to prevent the dovetail barb portion 3 and the packing main body 2 from being arranged so as to be lifted from the upper surface of the outer peripheral foundation 104 .

Next, a state in which a plurality of basic packings 1 are coupled (connected) in the longitudinal direction A will be described below with reference to FIGS. 8 and 9. FIG. 8 and 9, the basic packing 1 is drawn with the four elastic members 14 removed in order to facilitate understanding of the structure when the packing main bodies 2 are connected.

The base packing 1 is normally placed on the perimeter foundation 104 and fixed by being sandwiched between the base 120 and the perimeter foundation 104 . That is, when a plurality of foundation packings 1 are arranged between the outer peripheral foundation 104 and the foundation 120, as shown in FIG.
