Further, if the lower member flange 23 is trapezoidal and the flange hypotenuse 24 is shaped to be parallel to the inclined surfaces 15b and 15c of the steel deck 10 with a gap, the lower member flange 23 becomes the lower member flange. Since it becomes a positioning means at the time of fixing 20 to the mountain top surfaces 13a and 13b, fixing work becomes easy.
In addition, although the above has fixed the lower member 20 ranging over the peak surface 13a and the peak surface 13b formed in the same steel deck 10, this invention is not limited to this, In a pair of adjacent steel decks 10, the lower member 20 may be fixed across the peak surface 13 a of one steel deck 10 and the peak surface 13 b of the other steel deck 10. .
Further, the lower member 20 may be fixed across three or more peak surfaces of the steel deck 10. That is, the length of the lower member 20 is extended to provide two or more lower member flanges 23.
Furthermore, although the upper cylinder part 43 of the upper member 40 is cylindrical, it is not limited to this, It is a material of shapes, such as a square cylinder shape, H-section steel, or C-section steel, Comprising: Anything that can be transmitted is acceptable.
Further, in the above, the facility installation means provided in the upper member is the foundation side installation screw 45, while the installation means provided in the facility 500 such as the solar panel unit is the facility side installation hole 545 (with nut). However, the present invention is not limited to this.

FIG. 12 (a) is a sectional view in front view, and FIG. FIG. 12C is a cross-sectional view in front view showing a modification of the intermediate member that constitutes the equipment installation base of the deck base roof. In addition, the same code | symbol is attached | subjected to the part which is the same as that of Embodiment 1, or an equivalent part, and one part description is abbreviate | omitted.

(Fundamentals for equipment installation)
In FIG. 12A, a deck foundation roof equipment installation foundation (hereinafter referred to as “equipment installation foundation”) 400 includes a steel deck 10 having both ends fixed to a beam 90 of a structure (not shown). The lower member 20 spanned and fixed to the peak surface 13a and the peak surface 13b of the steel deck 10 and fixed to the lower member 20 via the tubular intermediate member 80, and installed on the foundation side And an upper member 40 provided with a working screw 45.
That is, since the intermediate member 80 is formed on the roof heat insulating material 91 and the waterproof sheet 92 installed so as to cover the entire surface of the steel deck 10, the entire upper member 40 is visually recognized on the waterproof sheet 92. . And the waterproof reinforcement sheet 60 is installed ranging over the upper cylinder part 43 and the upper bottom board 41 of the upper member 40. As shown in FIG.

(Intermediate member)
In FIG. 12B, the intermediate member 80 is a pipe (circular steel pipe) and is inserted into the intermediate member installation hole 94 formed in the roof heat insulating material 91. The tapping screw 74 can pass through the pipe of the intermediate member 80 (the inner diameter of the intermediate member 80 is slightly larger than the outer diameter of the tapping screw 74), and the length (height) of the intermediate member 80 is equal to that of the roof heat insulating material 91. The thickness is substantially the same.
In FIG. 12B, in order to exaggerate the arrangement of the members, a gap is drawn between them, but they may be in contact with each other.
In FIG. 12C, the intermediate member 81 is provided with intermediate heat insulating materials 83 at both ends of the intermediate pipe portion 82. An intermediate heat insulating material hole 84 is formed at the center of the intermediate heat insulating material 83 to facilitate penetration of the tapping screw 74.
Therefore, since the intermediate member 80 has a small cross-sectional area, the heat transfer amount from the upper member 40 to the lower member 20 (corresponding to the heat transfer amount from the equipment 500 to the beam 90) is small, but the heat transfer amount is smaller. The intermediate member 81 can be used to suppress it.

(Construction method)
FIG. 13 is a front sectional view for explaining the construction method of the foundation for installing the equipment for the deck base roof shown in FIG. 12 (a). FIG. 13 (a) shows a state in which a waterproof sheet is installed, FIG. 13 (b) shows a state in which an intermediate member installation hole is formed.
The construction method of the equipment installation foundation 400 is such that the longitudinal ends of the pair of beams 90 forming the structure are respectively installed on the steel deck 10 across the mountain top surface 13a and the mountain top surface 13b. And (fixed) the lower member 20 by the tapping screw 72,

Next, when the upper member 40 is placed on the waterproof sheet 92 so that the position of the facility-side installation hole 545 of the facility 500 to be installed matches the position of the foundation-side installation screw 45 of the upper member 40. A step of forming an intermediate member installation hole 94 that reaches the lower member 20 through the roof heat insulating material 91 and the waterproof sheet 92 at the position of the upper member hole 42 of the upper member 40 (see FIG. 13B). When,
Inserting the intermediate member 80 into the intermediate member installation hole 94;
A step of placing the upper member 40 on the intermediate member 80 and fixing the upper member 40 to the lower member 20 via the intermediate member 80 by a tapping screw 74 penetrating the upper member hole 42 and the pipe of the intermediate member 80;
Installing the waterproof reinforcing sheet 60 across a part of the upper cylindrical portion 43 of the upper member 40 and the waterproof sheet 92;
A step of solvent welding or heat welding between the end 61 of the waterproof reinforcing sheet 60 and the upper cylindrical portion 43 of the upper member 40 and between the end 62 of the waterproof reinforcing sheet 60 and the waterproof sheet 92. .

(Function and effect)
As described above, after the waterproof sheet 92 is installed, the facility installation foundation 400 forms the intermediate member installation hole 94, inserts the tubular intermediate member into the intermediate member installation hole 94, and replaces the upper member 40 with the lower member. 20 is fixed through the intermediate member 80 to the same effect as the equipment installation base 200 (can correspond to various installation positions of the equipment side installation holes 545 of the equipment 500, etc.). In addition, the following effects can be obtained.
Since the intermediate member installation hole 94 has a small diameter, the operation is easy. In addition, it is not necessary to install a heat insulating material in the intermediate member installation hole 94 (the upper heat insulating material 50 was necessary in the equipment installation foundation 200 and the equipment installation foundation 300). Is cheaper.
In the above description, each of the plurality of tapping screws 74 passes through the pipe of the intermediate member 80. However, the present invention is not limited to this, and for example, the upper member 40 is placed on one or more intermediate members 80. Then, the plurality of tapping screws 74 may be inserted into the waterproof sheet 92 and the roof heat insulating material 91 without penetrating the pipe of the intermediate member 80.

  Since the present invention is configured as described above, the position of the installation means for installing the equipment can be appropriately set without being restricted by the position of the top surface of the steel deck. It can be widely used as a foundation for the installation of equipment for deck base roofs installed on deck base roofs made of steel decks of various sizes.
