The present invention enables different numbers of heat exchanging bodies to be provided in one kind of tank floor member, improves versatility by widening a set range for heat exchanging capacity, and facilitates the manufacture, storage, and maintenance of the tank floor member. This tank floor member (20) having a rectangular plate shape constitutes the entirety or a portion of a floor part (F) of a tank (S) in which a medium (M) including a liquid and/or a solid can be filled, wherein tubular heat exchanging bodies (H) which perform heat exchange with the medium (M) are installed in a first direction (Ra) in the floor part (F), and the tank floor member (20) is provided in plurality in the first direction (Ra) to form a row-shaped part (21). The tank floor member (20) has: a first primary surface (22) which can form a floor surface (Fa) of the floor part (F); a second primary surface (23) which can form the floor surface (Fa) of the floor part (F); a pair of outer-side ends (24) disposed in the first direction (Ra); and a pair of joining-side ends (25) disposed in a direction perpendicular to the first direction (Ra) and shaped to be joined to each other, wherein one or more receiving grooves (26) which can receive and hold the heat exchanging bodies (H) in the first direction (Ra) are formed in each of the first primary surface (22) and the second primary surface (23), and the number of receiving grooves (26) formed in the first primary surface (26) and the number of receiving grooves (26) formed in the second primary surface (23) are different from each other. |
