JP-A-9-131274

  However, in the conventional example of the above-mentioned Patent Document 1, in the direct placement type in which the bus unit 20 is installed on the soil concrete 21 as shown in FIG. 4, when the bathroom is remodeled, the assembly of the bus unit 20 itself takes about one day. Complete. However, it is necessary to hit the soil concrete 21 in order to secure the strength of the place to be assembled. In this case, it takes several days for the soil concrete 21 to solidify. In the case of renovation work, it takes a few days for it to be completed and used after dismantling. As a result, there is a problem that it takes a long time from dismantling to completion of construction.

  On the other hand, in the suspension type using the suspension base 3 as shown in FIG. 5, the bus unit installation space 30 is opened between the suspension bases 3 and 3 and between the suspension base 3 and the base 2. The lower part of the bus unit installation space 30 generally communicates with the outside air, and the outside air easily goes around the bus unit 20 from below to enter the bathroom. Conventionally, it has been mentioned that it is cold as one of the complaints of users, and it is required to improve heat insulation when renovating.

  The present invention has been made in view of the above circumstances, and the object of the present invention is to shorten the construction period until the bus unit is installed and to easily ensure the airtight insulation at the place where the bus unit is installed. The object is to provide a bus unit installation structure.

  In order to solve the above-described problem, the bus unit installation structure according to the present invention suspends a plurality of suspension bases at intervals between a base surrounding the bus unit installation space of a building, and the suspension base is A plurality of plate heat insulating materials for airtightly covering the bus unit installation space on both sides of the main body portion. And a support for supporting each plate-like heat insulating material is integrally projected from the side surface of the base and the side surface of the main body.

  The present invention can shorten the construction period until the bus unit is installed, and can easily secure the airtight heat insulating property at the place where the bus unit is installed.

It is a perspective view explaining the airtight heat insulation structure of the bus unit installation space of this invention. It is a disassembled perspective view before installation of a plate-shaped heat insulating material same as the above. (A) is sectional drawing which follows the AA line of FIG. 1, (b) is sectional drawing which follows the BB line of FIG. (A) (b) is explanatory drawing of the conventional direct installation type bus unit installation structure. (A) (b) is explanatory drawing of the conventional suspension type bus unit installation structure.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective view of a construction state after the suspension base 3 and the plate-like heat insulating material 9 are installed in the bus unit installation space 30 of the building, and FIG. 2 is an exploded perspective view thereof. 10 in the figure is a pillar.

  A pair of bases 1, 1 facing each other and another pair of bases 2, 2 are installed so as to surround the bus unit installation space 30. The foundations 1 and 2 are each made of a wood-based square, and are laid along the upper surface of the foundation concrete.

  There are two types of bath units 20, one in which the bathtub and the washing place are integrated with the other, and the other in which the bathtub is a separate body and has a bathtub placing portion and a washing place to be placed later. Is not particularly limited.

  The suspension base 3 on which the bus unit 20 is installed includes a long suspension base body 5 and a pair of locking portions 4 provided at both ends in the longitudinal direction of the suspension base body 5.

  Legs 22 (FIG. 3) of the bus unit 20 are placed on the upper surface of the suspension base body 5. In order to support the weight of the bus unit 20, a strong square pipe (square steel pipe) is used for the suspension base body 5. The locking portion 4 is formed in an inverted L shape, is hooked on the upper surface of the base 1 (2), and is fixed with a screw 12.

  In order to shut off the lower outside air side and the upper indoor side in the bus unit installation space 30, the following airtight heat insulating structure is adopted.

  The plate-like heat insulating material 9 is formed or processed into a rectangular plate shape with a predetermined size. As a material for the heat insulating material, a material having low water absorption and strong against aging is suitable. In this example, an extruded polystyrene foam called Styrofoam (trade name) is used. Of course, the present invention is not limited to this, and various heat insulating materials such as other foamed polystyrene and foamed polyurethane may be used.

  In this example, the thickness of the plate-shaped heat insulating material 9 is set to be approximately equal to the thickness of the suspension base body 5.

  The length dimension of the plate-shaped heat insulating material 9 is set equal to the distance between the pair of bases 1 and 1 facing each other, and the width dimension is set equal to the distance between the adjacent suspension base bodies 5 and 5. When the suspension base 3 is arrange | positioned at equal intervals, the width dimension of the plate-shaped heat insulating material 9 is unified by the same width dimension according to this space | interval. In addition, when the suspension stand 3 is arrange | positioned at a different space | interval, it is set as a different width dimension according to the arrangement | positioning.

  The plate-like heat insulating material 9 is supported by a receiving tool. As shown in FIG. 2, the receiver includes a base-side receiver 6 (7) attached to the base 1 (2) and a suspension base-side receiver 8 projecting from the side surface of the suspension base body 5.

  A plurality of base-side supports 6 (a base-side receiver on one base 1 side is not shown) are attached to a plurality of locations on the opposing side surfaces of the pair of bases 1 and 1. The base side receiver 7 (the base side receiver on one base 2 side is not shown) is also attached to a plurality of locations on the opposite side surfaces of the other pair of bases 2 and 2. These base side receiving tools 6 and 7 are made of L-shaped metal fittings having the same structure, the vertical part is fixed to the side surface of the base 1 (2) by a nail or the like, and the base 1 of the plate-like heat insulating material 9 is placed on the horizontal part. (2) The end on the side is supported.

  On the other hand, suspension base side receiving tools 8 protrude from a plurality of locations on the side surface of the suspension base body 5. In this example, a part of the side wall of the square pipe constituting the suspension base body 5 is formed by cutting it into an L shape. That is, the suspension base side receiver 8 is formed integrally with the suspension base body 5. The end of the plate-shaped heat insulating material 9 on the side of the suspension base 3 is supported by these suspension base side receiving tools 8. These suspension base side receivers 8 project from the same height positions as the base side receivers 6 and 7, respectively.

  In construction, first, as shown in FIG. 2, a plurality of suspension bases 3 are suspended with a gap between a pair of bases 1 and 1 facing each other. Thereafter, the plate-like heat insulating material 9 is fitted from above so as to close the space on both sides of the suspension base body 5. At this time, both end portions 9 a and 9 b in the longitudinal direction of the plate-like heat insulating material 9 disposed between the adjacent suspension base main bodies 5 are supported by the base side support 6. The side end portions 9c, 9d of the plate-like heat insulating material 9 are supported by the adjacent suspension base side receiving tools 8. Further, both end portions 9 a and 9 b in the longitudinal direction of the plate-like heat insulating material 9 disposed between the base 2 and the suspension base body 5 adjacent thereto are supported by the base-side support 6. The side end portions 9c and 9d of the plate-like heat insulating material 9 are supported by a base-side support 7 and a suspension base-side support (not shown) opposite to the base-side support 7.

  As a result, the four sides of each plate-like heat insulating material 9 are supported by any one of the receptacles 6 (7, 8). Therefore, as shown in FIG. 1, the bus unit installation space 30 is airtightly closed without a gap by the plate-like heat insulating material 9 between the suspension bases 3. Thereafter, the installation work of the bus unit 20 is completed by placing the leg portions 22 (FIG. 3) of the bus unit 20 on the suspension base body 5.

  Therefore, according to the airtight heat insulating structure of the bus unit installation space 30, it is not necessary to hit the soil concrete required for the conventional direct placement type, so that the construction period can be greatly shortened. In addition, unlike the conventional suspension type, the plate-shaped heat insulating material 9 provides a good and stable airtight heat insulating performance. This makes it difficult for outside air or cold air to enter the bathroom from the lower part of the bus unit installation space 30. In addition, the support 6 (7, 8) that supports the plate-like heat insulating material 9 can be projected using the existing base 1 (2) and the suspension base 3. This eliminates the need for labor and cost for supporting the plate-like heat insulating material 9.

  In addition, since the load of the bus unit 20 is not applied to the plate-shaped heat insulating material 9, an excessive force does not act on the support 6 (7, 8) from above, and the plate by the support 6 (7, 8). There is also an advantage that the stable support of the heat insulating material 9 can be favorably sustained over a long period of time.

  Furthermore, both end portions 9a and 9b of the plate-like heat insulating material 9 are in contact with the bases 1 and 1, respectively, and both side portions 9c and 9d of the plate-like heat insulating material 9 are in contact with the suspension base body 5 or the base 2, respectively. Thereby, the plate-shaped heat insulating material 9 will be in the state by which the movement of the horizontal direction was controlled by the suspension stand 3 and the base 1 (2). As a result, even if an external force such as seismic force is applied from the lateral direction, the plate-like heat insulating material 9 has a structure that is difficult to come off from the support 6 (7, 8).

  In the above-described embodiment, the suspension base side receiver 8 is formed by horizontally cutting down a part of the side wall of the suspension base body 5. However, the present invention is not limited thereto. A configuration in which the metal fitting is fixed to the side surface of the suspension base body 5 is also possible.
