[0003] [Patent Document 1] JP 2017-57640 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in conventional center-post foundations, the exposed surface that is exposed along the floor surface is formed of a smooth metal plate, so that when the center post is not installed during normal times, it may become wet and slippery due to rain, etc. Therefore, it is considered to provide a non-slip protrusion on the exposed surface of the center-post foundation, but such a protrusion may reduce adhesion with the center post and waterproof board, affecting the waterproof board device's waterproof performance. [Means for solving the problem]

[0005] The present invention was created in consideration of the above-mentioned actual situation and with the aim of solving these problems.The invention of claim 1 is a center pillar base that supports the center pillar of a waterproof board device in an upright manner in an attachable and detachable manner, and comprises a base accommodating portion recessed into a floor portion and a base main body accommodated in the base accommodating portion, and the base main body has a first surface portion capable of supporting the center pillar in an upright position, and a second surface portion provided on the back side of the first surface portion and unable to support the center pillar in an upright position, and is configured to be switchable between a first state in which the first surface portion is exposed along the floor surface of the floor portion and able to support the center pillar in an upright position, and a second state in which the second surface portion is exposed along the floor surface and unable to support the center pillar in an upright position. The invention of claim 2 is a center column base as described in claim 1, characterized in that the base body can be switched between the first state and the second state based on a rotation operation with a rotation axis as a fulcrum. The invention of claim 3 is a center column base as described in claim 2, characterized in that the base body is connected to the base accommodating portion via a first pivoting support shaft and a second pivoting support shaft which are perpendicular to each other, and the base body is permitted to be inserted and removed from the base accommodating portion based on a rotation operation of the base body about the first pivoting support shaft, and the first surface portion and the second surface portion are permitted to be inverted based on a rotation operation of the base body about the second pivoting support shaft. The invention of claim 4 is the center pillar base according to any one of claims 1 to 3, characterized in that the second surface portion has a protrusion for preventing slipping. The invention of claim 5 is the center pillar base according to any one of claims 1 to 3, characterized in that the second surface portion is made of the same floor material as the floor portion. Effect of the Invention

[0006] According to the invention of claim 1, the base body of the center column base is configured to be switchable between a first state in which the first surface portion is exposed along the floor surface and the center column can be supported in an upright position, and a second state in which the second surface portion is exposed along the floor surface and the center column cannot be supported in an upright position. Therefore, it is possible to provide an anti-slip protrusion on the second surface portion or to form the second surface portion from any material without affecting the water-stopping performance. In addition, according to the invention of claim 2, the base body can be switched between the first state and the second state based on a rotation operation about a rotation axis, making it easy to switch between the first state and the second state. In addition, according to the invention of claim 3, the base body is permitted to be inserted and removed from the base accommodating section based on the rotation operation of the base body about the first rotating support shaft, and the first surface portion and the second surface portion are permitted to be inverted based on the rotation operation of the base body about the second rotating support shaft, so there is no need to secure rotation space for the base body within the base accommodating section, and as a result, the center column base including the base accommodating section can be made compact. According to the invention of claim 4, the second surface portion has a protrusion for preventing slipping, so that slipping of the second surface portion during normal operation when the center pillar is not installed can be suppressed. According to the invention of claim 5, the second surface portion is made of the same floor material as the floor portion, thereby improving the design of the floor portion during normal times when the center pillar is not installed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] [Waterproof board device] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. First, a waterproof board device 1 of a connected type to which a center pillar base 20 according to an embodiment of the present invention is applied will be described. In Fig. 1, 1 is a waterproof board device, and the waterproof board device 1 includes guide rails 2L, 2R, a center pillar 10, and waterproof boards 3A, 3B, and 3C.

[0009] In the following description, the width direction (longitudinal direction) of the waterproof boards 3A, 3B, 3C may be referred to as the left-right direction, the thickness direction of the waterproof boards 3A, 3B, 3C may be referred to as the front-rear direction, and the height direction of the waterproof boards 3A, 3B, 3C may be referred to as the up-down direction. In the front-rear direction, the side of the waterproof boards 3A, 3B, 3C that receives water pressure may be referred to as the outdoor side (front side), and the side that prevents water from entering may be referred to as the indoor side (rear side).

[0010] The guide rails 2L, 2R are, for example, extruded shapes or bent sheet metal, and are erected on both the left and right sides of the entrance 4. For example, the guide rails 2L, 2R in this embodiment are attached to the front faces of the side walls 5L, 5R arranged on both the left and right sides of the entrance 4, but they may also be attached directly to the inner surfaces of the side walls 5L, 5R, attached via shaped steel, or embedded in the side walls 5L, 5R.

[0011] The center column 10 is, for example, an extruded member or a bent sheet metal, and is detachably installed on the floor 6 of the entrance 4 between the pair of guide rails 2L, 2R. The center column 10 has a flange portion 10a at the lower end, and is fixed to the floor 6 via a pair of front and rear bolts 11 that penetrate the flange portion 10a from above. The center column 10 of this embodiment is fixed to the floor 6 (center column base 20) via two front and rear bolts 11, but the number and fixing positions of the bolts 11 are not limited to this, and can be appropriately changed depending on the shape of the center column 10, etc. For example, the center column 10 may be fixed to the floor 6 (center column base 20) with a total of four or more bolts 11 by arranging two or more bolts 11 at the front and rear of the center column 10.

[0012] The waterproof boards 3A, 3B, and 3C of this embodiment are, for example, metal panel materials, and are composed of a set of three sheets that can be stacked vertically in series and can be fitted together or separated from each other. Such split waterproof boards 3A, 3B, and 3C can be stored compactly in a warehouse when removed, and can be easily transported when used and removed.

[0013] Both widthwise ends of the waterproof boards 3A, 3B, 3C are inserted into the insertion grooves M formed in the guide rails 2L, 2R and the center post 10, and are thereby held so as to block the entranceway 4. Specifically, when both widthwise ends of the waterproof boards 3A, 3B, 3C are inserted from above into the insertion grooves M of the guide rails 2L, 2R and the center post 10, starting from the lower waterproof boards 3A, 3B, 3C, the waterproof boards 3A, 3B, 3C are guided by the guide rails 2L, 2R and the center post 10 to move downward, and are stacked in order to form a waterproof wall W at the entranceway 4.

[0014] In this embodiment, waterproof walls W are formed between the left guide rail 2L and the center post 10, and between the right guide rail 2R and the center post 10, but the number of waterproof boards 3A, 3B, 3C forming each waterproof wall W is not limited to three, but may be one or two, or may be four or more.

[0015] Furthermore, at least the lower end surface of the waterproof board 3A located at the lowest level is provided with a waterproof material 3a that abuts against the floor surface 6a of the floor section 6. The waterproof material 3a is made of a rubber-like elastic material, and by elastically abutting against the floor surface 6a, it suppresses water leakage between the lower end surface of the waterproof board 3A and the floor surface 6a. Therefore, it is desirable that the floor surface 6a be as smooth as possible.

[0016] [Middle pillar base] Next, the center pillar base 20, which is a main part of the present invention, will be described with reference to FIG. 2 and subsequent figures.

[0017] 2 to 6, a center column base 20 for detachably supporting the center column 10 is embedded in the center column erection position of the floor section 6. The center column base 20 includes a base receiving portion 21 recessed in the floor section 6, and a base main body 22 received in the base receiving portion 21.

[0018] The base accommodating section 21 includes an anchor member 23 that is driven into the recess 6b of the floor section 6, a metal box 24 that has a box shape that opens upward and is fixedly supported by the anchor member 23 in the recess 6b, and a filler 25 such as mortar that is filled between the recess 6b and the box 24. Note that a water-stopping material (rubber elastic member) (not shown) that elastically abuts against the side surface of the base main body 22 can be provided on the side wall portion (circumferential edge portion) of the box 24 that accommodates the base main body 22 in order to improve water-stopping performance.

[0019] The base body 22 comprises a first surface 26 capable of supporting the center column 10 in an upright position, and a second surface 27 provided on the back side of the first surface 26 and unable to support the center column 10 in an upright position. The first surface 26 is formed of a flat metal plate and has two screw holes 26a into which the above-mentioned bolts 11 are screwed. The second surface 27 has a rectangular recess 27a, and the surface of the second surface 27 is formed by an engagement member 28 that is fitted into the recess 27a. As the engagement member 28, for example, one having a non-slip projection 28a on the surface or one made of the same floor material as the floor section 6 can be selected as shown in FIG. 6(a).

[0020] The base body 22 can be switched between a first state (see Figs. 2 to 4, Fig. 5(d), and Fig. 6(b)) in which the first surface portion 26 is exposed along the floor surface 6a of the floor portion 6 and can support the center column 10 in an upright position, and a second state (see Figs. 5(a) and 6(a)) in which the second surface portion 27 is exposed along the floor surface 6a and cannot support the center column 10 in an upright position. According to such a center column base 20, since the second surface portion 27 of the base body 22 can be in an exposed state during normal times when the center column 10 is not installed, it is possible to provide a non-slip protrusion 28a on the second surface portion 27 or to form the second surface portion 27 from any material without affecting the water-stopping performance.

[0021] 5(a) to 5(d), the base body 22 is switched between a first state and a second state based on a rotation operation about the rotation support shafts 31 and 32. The base body 22 in this embodiment is connected to the base housing section 21 via a first rotation support shaft 31 and a second rotation support shaft 32 that are perpendicular to each other, and the base body 22 is allowed to be inserted and removed from the base housing section 21 based on a rotation operation of the base body 22 about the first rotation support shaft 31, and the first surface section 26 and the second surface section 27 are allowed to be inverted based on a rotation operation of the base body 22 about the second rotation support shaft 32.

[0022] With such a center column base 20, there is no need to secure rotation space for the base main body 22 within the base accommodating section 21, so not only can the center column base 20 including the base accommodating section 21 be made compact, but the base main body 22 can be held non-rotatable within the base accommodating section 21.

[0023] More specifically, the base main body 22 is connected to the base housing portion 21 via a hinge 33. The hinge 33 includes a fixed piece 34 fixed to one end of the base housing portion 21 and a movable piece 35 rotatably connected to an upper end of the fixed piece 34 via a first rotating support shaft 31 which is a hinge shaft.

[0024] Fig. 5(a) shows the center pillar base 20 in the second state, and in this state, as shown in Fig. 6(a), the second surface portion 27 of the base body 22 is exposed along the floor surface 6a. In this state, when the base body 22 is lifted by inserting a finger or a tool into the gap C secured between the base body 22 and the base housing portion 21, the base body 22 rotates about the first rotating support shaft 31 and can be put into an upright position as shown in Fig. 5(b). The base body 22 in the upright position can be rotated about the second rotating support shaft 32, and when it is rotated 180° about the second rotating support shaft 32 as shown in Fig. 5(c), the second surface portion 27 and the first surface portion 26 are inverted. Thereafter, when the base body 22 is accommodated in the base accommodation section 21 by a rotation operation with the first rotation support shaft 31 as a fulcrum, the center column base 20 enters the first state as shown in Fig. 5(d). In this state, the first surface section 26 of the base body 22 is exposed along the floor surface 6a, so that the center column 10 can be supported upright via the bolt 11.

[0025] According to the present embodiment configured as described above, the center column base 20 supports the center column 10 of the waterproof board device 1 in an upright manner in an attachable and detachable manner, and comprises a base accommodating portion 21 recessed in the floor portion 6 and a base main body 22 accommodated in the base accommodating portion 21. The base main body 22 comprises a first surface portion 26 capable of supporting the center column 10 in an upright position, and a second surface portion 27 provided on the back side of the first surface portion 26 and unable to support the center column 10 in an upright position. The base main body 22 is configured to be switchable between a first state in which the first surface portion 26 is exposed along the floor surface 6a of the floor portion 6 and is able to support the center column 10 in an upright position, and a second state in which the second surface portion 27 is exposed along the floor surface 6a and is unable to support the center column 10 in an upright position. Therefore, it is possible to provide an anti-slip protrusion 28a on the second surface portion 27 or to form the second surface portion 27 from any material without affecting the water-stopping performance.

[0026] Furthermore, since the base body 22 can be switched between the first state and the second state based on a rotation operation about the rotation support shafts 31, 32 as fulcrums, the operation of switching between the first state and the second state can be easily performed.

[0027] In addition, the base body 22 is connected to the base housing section 21 via a first pivot shaft 31 and a second pivot shaft 32 that are perpendicular to each other, and the base body 22 is allowed to be inserted into and removed from the base housing section 21 based on the rotation of the base body 22 about the first pivot shaft 31, and the first surface section 26 and the second surface section 27 are allowed to be inverted based on the rotation of the base body 22 about the second pivot shaft 32, so there is no need to ensure a rotation space for the base body 22 within the base housing section 21. This not only makes it possible to make the center column base 20 including the base housing section 21 compact, but also makes it possible to hold the base body 22 in the base housing section 21 in a non-rotatable state.

[0028] [Other embodiments] Next, a center pillar base 20B according to a second embodiment of the present invention will be described with reference to Figures 7 and 8. However, the same reference numerals as in the first embodiment are used for the configurations common to the first embodiment, and the description of the first embodiment may be used.

[0029] 7 and 8, the center pillar base 20B of the second embodiment differs from the first embodiment in that the base body 22B is rotated around only one rotation shaft 36. That is, the base body 22B is rotatably connected to the base housing portion 21B via one horizontal rotation shaft 36, and the first surface portion 26B and the second surface portion 27B are allowed to be inverted based on the rotation of the base body 22B around the rotation shaft 36. According to the second embodiment of the center column base 20B, although it is necessary to secure space for rotation of the base main body 22B within the base accommodating section 21B, it is possible to switch between a first state in which the first surface portion 26B is exposed along the floor surface 6a of the floor section 6 and the center column 10 can be supported in an upright position (see Figures 7(c) and 8(b)), and a second state in which the second surface portion 27B is exposed along the floor surface 6a and the center column 10 cannot be supported in an upright position (see Figures 7(a) and 8(a)).
