It is to be placed.

  As shown in FIGS. 1 and 2, the foundation frame 110 is a rectangular concrete frame, and is made of a cocoon-shaped precast concrete product whose upper and lower surfaces are open. As will be described later, the foundation frame 110 is embedded in six installation holes excavated on the ground surface where the capacitor is installed. As will be described later, the foundation frame 110 is filled with a concrete material (fixing material) 112, whereby the support column 120 is erected and fixed at a predetermined position and height in the foundation frame 110.

  The support 120 is a support member that plays a role of supporting the storage battery support frame 140. In this embodiment, as shown in FIGS. 1 and 2, an H-section steel is used as the support 120. The lower part 120a of the support column 120 is inserted into the foundation frame 110, and the upper part 120b of the support column 120 protrudes from the opening on the upper surface of the foundation frame 110 (FIGS. 2A and 3). As will be described later, a height adjusting member (erection member) 130 is attached to the middle side surface of the support column 120 in the vertical direction (FIGS. 2 and 3).

  As shown in FIGS. 1 to 3, the height adjustment member (construction member) 130 has a role of aligning the height H (FIGS. 3A and 3B) from the ground to the upper ends of the six columns 120. It is the member which fulfills. Its shape is L-shaped, and its length is longer than the length of one side of the foundation frame 110. A bolt hole is formed in the flange 130a of the height adjusting member 130, and is attached to the side surface of the column 120 via two bolts 122 in a state of being laid on the upper surface of the foundation frame 110 (FIGS. 2 and 2). 3). Since the height adjusting member 130 is installed on the upper surface of the foundation frame 110, as will be described later, the lower portion 120a of the support column 120 is filled until the foundation frame 110 is filled with a concrete material (fixing material) and solidified. Can be maintained in the base frame 110. In addition, although the material of the height adjustment member 130 of this embodiment is stainless steel, you may use the aluminum which can ensure predetermined intensity | strength, the coated plain steel, etc.

  As shown in FIG. 1, the battery support frame 140 is constructed so as to be supported on the upper ends of the six columns 120. More specifically, the capacitor support frame 140 includes two girder members 140a, three horizontal members 140b that connect the girder members 140a, and four flat brace members 140c. The beam member 140a and the horizontal member 140b are fixed to the upper ends of the respective columns 120 via fixing bolts (not shown). Further, the flat brace material 140c is fixed to a gusset plate attached to the end of the beam member 140a by a fixing bolt 142. Further, a brace material 146 is provided at each column position. One end of the brace material 146 is fixed to the vicinity of the upper end portion of the support column 120 via a fixing bolt 144, and the other end is fixed to the lower surface of the beam member 140a or the horizontal member 140b via a fixing bolt 144. The girder material 140a, the horizontal frame material 140b, and the flat brace material 140c play a role of placing a capacitor (not shown), and the brace material 146 plays a role of increasing the mechanical strength and earthquake resistance of the capacitor frame 100. In addition, although the material of the capacitor | condenser support frame 140 of this embodiment is stainless steel, you may use aluminum, common steel, etc. as mentioned above.

  Next, the construction method of the battery stand 100 according to the embodiment of the present invention will be described with reference to the drawings.

The construction method of the battery stand 100 according to the embodiment of the present invention is as follows:
(A) a step of burying six foundation frames 110 on the ground surface;
(B) inserting the column 120 into the foundation frame 110;
(C) fixing the height adjusting member (erection member) 130 to the side surface of the support column 120 and erection the height adjusting member 130 on the upper surface of the foundation frame 110;
(D) attaching a capacitor support frame (heavy object support frame) 140 to the upper end of each support 120;
(E) filling the concrete material (fixing material) 112 in the foundation frame 110;
including.

  The step (A) will be described. In the step (A), six installation holes are excavated at equal intervals (3 × 2) vertically and horizontally on the ground surface where the capacitor base 100 is provided (FIGS. 1 and 4A). The foundation frame 110 is buried, and the gap between the foundation frame 110 and the installation hole is reliably backfilled (FIG. 3).

  Next, the said process (B) is demonstrated. In the step (B), the lower portion 120 a of the support column 120 is inserted into the foundation frame 110.

  Next, the said process (C) is demonstrated. In the step (C), a height adjusting member (erection member) 130 is provided on the side surface of the column 120 so that the height H (FIGS. 3A and 3B) from the ground to the upper end of each column 120 is aligned. The height adjustment member 130 is installed on the upper surface of the foundation frame 110 by fixing. For example, the height of the top surfaces of the six foundation frames 110 may not be uniform due to unevenness in the ground surface where the capacitor base 100 is provided or due to different depths of the installation holes. For example, when the height of the upper surface of one of the six base frames 110 is higher by Δh than the other portions, the height adjusting members 130 at the 120 struts are attached to the mounting positions of the other struts 120. It is mounted at a position higher than Δh. By doing so, the heights H up to the upper ends of the six columns 120 can be made uniform. Since the length of the height adjusting member 130 is longer than the outer length of the foundation frame 110 (FIG. 2), the height adjusting member 130 can be installed on the upper surface of the foundation frame 110. Thus, before the concrete material (fixing material) 112 is filled in the foundation frame 110 in the step (E) by the height adjusting member 130, the support column 120 can be temporarily supported in the foundation frame 110. it can. As shown in FIG. 3B, when a long hole 120c is formed in the side surface of the support 120 and the height adjusting member 130 is attached through the long hole 120c, the height adjusting member at the time of temporary support is provided. The final height fine adjustment of 130 can be easily performed.

  Next, the said process (D) is demonstrated. In the step (D), the capacitor support frame 140 is attached to the upper end of each column 120. More specifically, as shown in FIG. 1, the beam member 140a and the horizontal member 140b are attached to the upper end of each column 120 via a fixing bolt (not shown). Further, the four flat brace members 140c are attached to the end portions of the beam member 140a by the fixing bolts 142 through the gusset plates. Further, one end of the twelve brace members 146 is attached to the vicinity of the upper end portion of the support column 120 via a fixing bolt 144, and the other end of the brace member 146 is attached to the lower surface of the beam member 140a or the horizontal member 140b via the fixing bolt 144. Install.

  Next, the said process (E) is demonstrated. In step (E), a concrete material (fixing material) 112 is filled into the foundation frame 110. Since the upper ends of the columns 120 are temporarily supported by the height adjusting member (erection member) 130 in a state in which the heights are aligned, the foundation frame is re-adjusted without adjusting the height of the column 120 again. 110 can be filled with a concrete material (fixing material) 112. By filling the foundation frame 110 with the concrete material (fixing material) 112, the mechanical strength and the earthquake resistance of the battery stand 100 can be improved. In addition, you may use a mortar as a fixing material.

  As described above, in the construction method of the battery stand 100 according to the embodiment of the present invention, the foundation frame 110 is embedded in the ground surface, and the support 120 and the battery support frame 140 are assembled and then the concrete material is placed in the foundation frame 110. (Fixing material) 112 is filled and installed. The conventional gantry with the concrete foundation requires a special builder for concrete foundation construction, and the gantry is installed after the concrete foundation is stabilized, which takes time and cost. In the construction method of the battery gantry 100 according to the embodiment of the present invention, the capacitor gantry 100 can be simply installed without applying the concrete foundation that has been necessary in the past. Construction costs can be reduced.

  Moreover, the construction method of the battery stand 100 according to the embodiment of the present invention uses the height adjusting member (erection member) 130 to increase the height H from the ground to the upper end of each column 120 (FIG. 3A). , (B)) can be easily arranged. In a conventional gantry with a concrete foundation, if the heights of the columns are not uniform, it is necessary to remove the concrete foundation and re-install it, which takes time and cost. On the other hand, in the battery stand 100 according to the embodiment of the present invention, the ground surface of the place where the battery stand 100 is provided is uneven or the depth of the installation hole for burying the foundation frame 110 is different. Even when the height positions of the upper surfaces of the six foundation frames 110 are not aligned, the height from the ground to the upper end of each column 120 can be obtained by attaching the height adjusting member (erection member) 130 to the side surface of the column 120. H (FIGS. 3A and 3B) can be easily arranged. For this reason, the distortion of the whole battery stand 100 supported by the plurality of support columns 120 can be easily eliminated.

  In addition, the column 120 of the battery stand 100 according to the embodiment of the present invention is firmly supported by the concrete material (fixing material) 112 filled in the foundation frame 110 after the height adjustment, and thus a large-sized battery Even when a heavy object is placed, the structure is excellent in mechanical strength and earthquake resistance.

  In addition, this invention is not limited to the said embodiment, A various deformation | transformation and application are possible. For example, in the present embodiment, the configuration of the capacitor stand 100 on which the capacitor (not shown) is mounted has been described, but a heavy object other than the capacitor can also be mounted. For example, a disaster prevention radio, a security camera, lighting, or the like may be placed. In addition, the length of the support 120 and the size of the capacitor support frame 140 can be changed in view of the size of the object to be placed on the gantry, the application, and the like.

  In the present embodiment, a height adjusting member (an erection member) is provided on the side surface of the column 120 so that the height H (FIGS. 3A and 3B) from the ground to the upper end of each column 120 is aligned. Although the form which fixes 130 was demonstrated, when the height of the upper surface of each foundation frame 110 was able to be equalized at the time of embedding the foundation frame 110 in the installation hole, it is not necessary to adjust height.

  Further, in the present embodiment, as shown in FIG. 3B, a long hole 120c is formed in the side surface of the support column 120, and a height adjusting member (erection member) 130 is attached through the long hole 120c. However, any mechanism that can adjust the height of the mounting position of the height adjusting member 130 can be used as appropriate. For example, a plate in which a long hole is formed on the side surface of the column 120 may be attached, and the height adjusting member 130 may be attached through the long hole.

  In the present embodiment, as shown in FIGS. 1 and 3A, the form in which the upper part is supported by the brace material 146 has been described. However, the weight of the object placed on the gantry is small, and the brace material 146 is used. The brace material 146 may not be provided if the mechanical strength and the earthquake resistance are maintained even without the brace.

  Moreover, in this embodiment, as shown in FIG. 1, FIG. 4 (a), about the form which excavated six installation holes for embedding the foundation frame 110 in the ground surface of the place in which the electrical storage stand 100 is provided.
