The front-side metal skin 42 is disposed above the back-side metal skin 41 at an interval. Similar to the back side metal skin 41, the front side metal skin 42 is made of, for example, a galvanized steel plate, a coated steel plate, a Galvalume steel plate (registered trademark), SGL (registered trademark), a stainless steel plate, or the like.

  The front metal shell 42 is provided with a plurality of protrusions 421 that protrude upward. As shown in FIG. 1, each of the plurality of protrusions 421 extends in the length direction of the sandwich panel 4, and more specifically, the entire length of the sandwich panel 4 in the length direction (that is, the girder direction). Continuous. The plurality of protrusions 421 are arranged at a constant interval in the width direction of the sandwich panel 4 (that is, the beam direction).

  The core material 43 is filled between the back side metal skin 41 and the front side metal skin 42. The core material 43 is comprised with the material which has heat insulation. The core material 43 is made of, for example, a foamable resin having excellent heat insulating properties such as polyisocyanurate foam or rigid polyurethane foam, or an inorganic material such as rock wool or gypsum board.

  As shown in FIG. 3, the first connection portion 51 is formed at one end portion of the both ends in the width direction of the sandwich panel 4, and the second connection portion 52 is formed at the other end portion. . The 1st connection part 51 and the 2nd connection part 52 are formed in the structure which can be connected mutually, Thereby, the some sandwich panel 4 is connected by the beam direction. The sandwich panel 4 of the present embodiment is fixed to the flange portion 324 of the upper chord member 32 by driving the fixing tool 6 from above in a state where the first connection portion 51 and the second connection portion 52 are connected. . In the sandwich panel 4, the fixing tool 6 is driven at a position corresponding to the upper chord member 32 in the length direction. Thereby, the sandwich panel 4 can connect the plurality of beams 3 to each other.

  Thus, in the building of this embodiment, the plurality of structures 1 are connected by the sandwich panel 4 having excellent mechanical strength. For this reason, according to the building of this embodiment, many main buildings which become essential for a general building become unnecessary, and it can be set as the building excellent in cost and workability. The sandwich panel 4 includes a core material 43 having heat insulation properties. For this reason, only by installing the sandwich panel 4 on the beam 3, it is possible to impart heat insulation performance to the roof, and it is not necessary to perform the work of laying the heat insulating material along the bottom of the roof, thereby improving the workability.
