Description

The present invention relates to an installation structure in which an installation body is installed on a construction material, an installation body used in the installation structure, and an installation method for the installation body.

Conventionally, various installation means have been used to support and secure the installation body to construction materials (general structures) such as studs and wall materials behind walls. In particular, when the construction material, a pillar material, and the wall material fixed to the front of the pillar material are separated by furring strips or the like, the installation position in the front-to-rear direction of the installation body is determined taking into account the distance between the front of the pillar material and the back of the wall material.

Patent Document 1 discloses an installation structure for an arrangement body in which the arrangement position of the arrangement body is determined based on the front surface of the pillar material when a wall material is fixed to the front surface of the pillar material at a position separated from the front surface of the pillar material. In the following paragraphs, the reference numerals of Patent Document 1 are shown in parentheses. The arrangement body (100) comprises a housing-shaped arrangement body main body (110) and an arrangement body support (120) that supports the arrangement body main body (110). The arrangement body support (120) is a long plate that is L-shaped in a plan view and extends from its base end to its tip, and is composed of an abutment portion (121) located at its base end and arranged to abut against the side surface (P1) of the pillar material (P), and a support portion (122) that is longitudinally extended from the abutment portion (121) toward its tip (or the side of the pillar material (P)). The installation support (120) has a protrusion (123) that can selectively protrude laterally from the abutment portion (121) so as to abut against the front surface (P2) of the pillar material (P). The protrusion (123) rotates in a direction opposite to the support portion (122) about the hinge portion (123b) as an axis, and can protrude laterally at a substantially right angle from the abutment portion (121). In the protruding state of the protrusion (123), the abutment surface (123a) of the protrusion (123) faces the same direction as the back surface of the support portion (122), and can abut against the front surface (P2) of the pillar material (P). In the installation structure (10), the installation body (100) is disposed relative to the pillar material (P) so that the abutment portion (121) of the installation body support (120) abuts against the side surface (P1) of the pillar material (P) and the abutment surface (123a) of the protrusion (123) abuts against the front surface (P2) of the pillar material (P). That is, in the installation body (100) and its installation structure (10) of Patent Document 1, the position of the front surface portion (110) of the installation body main body (110) is determined based on the front surface (P2) of the pillar material (P).

As an example of a structure in which a gap is formed between the front surface of a column material and the back surface of a wall material, Patent Document 2 discloses a partition wall structure in which two rows of studs are arranged in a staggered pattern between upper and lower runners, and wall materials are fixed to the front (or back) of the wall materials in each row. In the following paragraphs, the reference numbers for Patent Document 2 are shown in parentheses. The partition wall (1) structure of Patent Document 2 comprises upper and lower runners (11, 12), a number of studs (15, 16, 17) arranged side by side at a predetermined interval and erected between the upper and lower runners (11, 12), and a pair of gypsum boards (22, 23) attached to the front and back surfaces so that the studs (15, 16, 17) are installed inside.

The installation body of Patent Document 1 is positioned by abutting the protruding portion of the installation body support against the front surface of the pillar material. However, in the conventional technology, when installing an installation body in a structure in which a wall material is already fixed to the front side of the pillar material, it is difficult to use the protruding portion to align the body with the front surface of the pillar as a reference. Similarly, when installing an installation body in a partition wall structure having two or more pillar materials at the front and rear, as in Patent Document 2, it is difficult to perform positioning with the installation body of Patent Document 1 because the front surface of the pillar material is used as a reference.

The present invention has been made to solve the above problems, and its purpose is to provide an arrangement body installation structure that makes it easier to position the arrangement body in the front-to-rear direction, an arrangement body used in the arrangement body installation structure, and an installation method for the arrangement body.

The arrangement installation structure according to claim 1 is an arrangement installation structure including a front wall having a wall surface on a front side, a rear wall facing the front wall and having a wall surface on a rear side, a plurality of pillars erected at intervals in a back-of-wall space between the front wall and the rear wall, and an arrangement arranged at a predetermined position in the back-of-wall space and having a front surface facing the front wall,

In other words, the arrangement body installation structure of the present invention does not align the arrangement body based on the front surface of the first pillar material against which the front wall abuts, but aligns the arrangement body based on the front surface of the second pillar material against which the rear wall on the side against which the front surface of the arrangement body abuts, so that even when the front wall is erected, it is possible to easily position the arrangement body in the front-to-rear direction by utilizing the gap.

According to the invention described in claim 2, the alignment section determines the installation position of the arrangement body in the front-to-rear direction based on the rear surface of the pillar material, and aligns the front surface of the arrangement body to a position rearward of the rear surface position of the front wall. In other words, the arrangement body installation structure of the present invention aligns the arrangement body not based on the front surface of the pillar material on which the front wall is formed, but based on the rear surface of the pillar material, making it possible to easily position the arrangement body in the front and rear directions even when the front wall is erected.

According to the invention described in claim 3, in addition to the effects of the inventions of claims 1 and 2, a gap is formed between the back surface of the front wall and the front surface of the arrangement body, and the arrangement body is allowed to slide forward until the front surface of the arrangement body reaches the back surface of the front wall. This makes it possible to adjust the front-to-rear position of the arrangement body as necessary, even after the arrangement body is fixed to the pillar material, and arrange the arrangement body so that it abuts against the back surface of the front wall.

According to the invention described in claim 4, the arrangement is provided with an alignment means formed on the side of the arrangement body and for determining the longitudinal arrangement position of the arrangement body relative to the pillar material using the rear surface of the pillar material as a reference. The arrangement body is aligned with the rear surface of the pillar material by the alignment means, and the arrangement body is supported on the pillar material by the support device, making it possible to easily align the arrangement body and install it in a predetermined position.

According to the invention described in claim 5, the positioning unit determines the installation position of the arrangement body using the rear surface of the first pillar material or the front surface of the second pillar material as a reference surface, and the front surface of the arrangement body can be positioned rearward of the rear surface position of the front wall. In other words, the installation method of the present invention does not align the arrangement body to the reference surface of the front surface of the first pillar material against which the front wall abuts, but aligns the arrangement body using the rear surface of the first pillar material as a reference surface, or aligns the arrangement body using the second pillar material against which the rear wall on the side against which the front surface of the arrangement body abuts as a reference surface. Therefore, even when the front wall is erected, it is possible to easily position the arrangement body forward and backward by utilizing the gap.

According to the invention described in claim 6, the positioning unit determines the installation position of the arrangement body based on the rear surface of the pillar material, and the front surface of the arrangement body can be aligned to a position further back than the rear surface of the front wall. In other words, the installation method of the present invention does not align the arrangement body based on the front surface of the pillar material on which the front wall is formed, but aligns the arrangement body based on the rear surface of the pillar material, so that even when the front wall is erected, it is possible to easily position the arrangement body front and rear.

The installation body 100 of one embodiment of the present invention is mainly arranged on construction materials such as studs behind a wall, and an installation body that allows devices such as switches and outlets to be attached to the surface of the wall material is installed in the space behind the wall. The "installation body" in this invention is arranged on a pillar material (construction material), and in this embodiment, a combination of a box 101 and a support device 102 is shown, but it also includes a form that does not include a box (only the support device 102). In this embodiment, the "installation body" is exemplified as a box 101 for wiring, but the installation body of the present invention is not limited to a box. The "installation body" of the present invention may be a member other than a box, such as a cable holder or a pipe clip. Alternatively, when the "installation body" is a form that does not include a box, the "installation body" may be interpreted as a support device or support body itself for supporting the box.

The installation body 100 of one embodiment of the present invention is a device for constructing an installation body installation structure 10 and/or a support structure 11 for arranging equipment, etc., and comprises a box 101, which is the installation body main body, and a support device 102. Figure 1 is an exploded perspective view of the installation body 100 (or support device 102) of one embodiment of the present invention. As shown in Figure 1, the installation body 100 comprises a box 101, which is the installation body main body that is placed behind a wall, and a support device 102 that is fixed to a pillar material, which is a construction material, and supports the box 101. Each component will be described in detail below.

The box 101 constituting the arrangement 100 of one embodiment will be described with reference to Figures 2 to 4. Figure 2 is a schematic perspective view of the box 101 from the front. Figures 3(a) to 3(d) are plan, front, side and rear views of the box 101. Figure 4 is a cross-sectional view of the box 101 taken along lines A-A and B-B.

2 to 4, the box 101 is in the shape of a bottomed box, and has a rectangular bottom wall extending vertically and horizontally, and side walls erected from the inner surface of the bottom wall. Here, the vertical direction (or vertical axis direction) of the box 101 in a front view corresponds to the extension direction of the pillar material, and the left-right direction (or horizontal axis direction) in a front view corresponds to the extension direction of the support arm portion 132. An opening is provided on the front surface, which is the opposite side of the bottom wall, bordered by the tip edge of the side wall. In addition, a flange 101a is provided at the tip of the side wall, extending outward from the opening so as to abut against the back surface of the front wall (wall material) constructed in front of the construction material. In addition, a pair of device mounting portions 101b are formed on the edge end faces on both the upper and lower sides of the opening as a pair of holes for mounting wiring devices such as outlets and switches.

The box 101 has a reference position at its center 101c, which is the reference for positioning. The center 101c (reference position) of the box 101 is an index for determining the position of the box 101 in the plane of the front wall. That is, the reference position of the box 101 is located at the height and horizontal position coordinates that are preset when the installation structure is designed. Here, this reference position coincides with the center of the wall hole drilled in the front wall. In addition, two attachment holes 101d are drilled in the bottom wall of the box 101 for attaching the box 101 to the support arm 132 of the support body 130 with a screw (or tapping screw). In other words, the attachment portion is the portion where the box 101 is attached to the support arm 132 through the two attachment holes 101d. These two attachment holes 101d are arranged side by side in the horizontal axis direction, sandwiching the center of the bottom wall. In the box 101 of this embodiment, the center 101c and the attachment hole 101d (attachment portion) coincide in the height direction. However, as shown in FIG. 20, the two may differ in height.

As shown in FIG. 4, the box 101 of this embodiment is composed of a box body 101e made of synthetic resin and a sound-insulating cover 101f made of a sound-insulating material. That is, the sound-insulating cover 101f is attached to the exterior of the box body 101e. The sound-insulating cover 101f is made of a soft rubber material with a specific gravity of 2 or more so as to have sound-insulating properties, and is formed in a bottomed box shape with an opening on the front, and houses and covers the box body 101e made of synthetic resin. The flange 101a is formed as a part of the sound-insulating cover 101f, and functions to seal the wall hole by coming into close contact with the periphery of the wall hole when installed, as described later.

The installation body of this embodiment is not limited to the above embodiment. For example, the installation body may be provided with fire resistance. Specifically, in order to provide fire resistance, the peripheral wall of the installation body may be made of steel, or the installation body may be provided with an additional member such as a thermally expandable putty. In general, an installation body provided with fire resistance or sound insulation performance has a higher weight than one that does not have such performance.

Next, the support device 102 and its components will be described with reference to Figures 5 to 12. Figure 5 is a schematic perspective view of the support device 102. Figures 6(a) to 6(c) are plan, front, and side views of the support device 102. Figures 7(a) to 7(c) are C-C and D-D cross-sectional views of the support device 102. Figures 8(a) and 8(b) are schematic perspective views of the base body 110 as viewed from the front and rear. Figures 9(a) to 9(c) are plan, front, and side views of the base body 110. Figure 10 is a schematic perspective view of the support body 130. Figures 11(a) to 11(c) are plan, front, and side views of the support body 130. Figure 12 is a schematic diagram showing an engagement pattern by the connection mechanism of the base body 110 and the support body 130.

The support device 102 is configured in a longitudinal shape so as to support the box 101 to the side of a pillar material, which is a construction material, while being fixed to the pillar material. As shown in Figures 5 to 7, the support device 102 includes a base body 110 as a fixed part that is fixed to the pillar material, and a support body 130 for supporting the box 101. The support device 102 is configured by assembling the support body 130 to the base body 110 via a connecting mechanism. The connecting mechanism movably connects the base body 110 and the support body 130.

As shown in Figures 8 and 9, the base body 110 is a plate piece bent into an L-shape in plan view. The base body 110 has one side surface facing the side (extension direction of the support 130) and the other side surface (or fixed surface) facing the pillar material, and is equipped with a base portion 111 extending from the rear end to the front end, and an addressing portion 112 bending and extending from the front end of the base portion 111 to the opposite side of the extension direction of the support 130.

The base 111 is made of a rectangular flat plate and has multiple fixing holes 111a for fixing to the side of the pillar material with fixing screws. The fixing holes 111a are round holes and long holes formed above and below the base 111. In addition, the base 111 has a scale 111b formed adjacent to the fixing hole 111a. The scale 111b indicates the distance from the front edge of the base 111. When a furring strip is installed between the front surface of the pillar material and the front wall, the fixing position of the base 111 can be shifted to the front side of the pillar material by the thickness of the furring strip using the scale 111b. In addition, the base 111 is configured as a connected part so that the connecting part 131 of the support 130 is connected on the opposite side to the fixed surface. That is, in the base body 110, the base 111 functions as a fixed part that is fixed to the outer surface of the pillar material and as a connected part to which the support 130 is connected.

In addition, one side of the base 111 (facing the support 130) is provided with a pair of rails 115 extending forward and backward, and a plurality of locking pieces 116 formed along the extension direction of the rails 115. These rails 115 and locking pieces 116 can function as part of a connecting mechanism that connects the support 130 to the base body 110. As described below, the rails 115 preferably have a length in the forward and backward directions that can guide the movement of the support 130 until the arrangement body 100 reaches the rear surface position of the front wall (or abuts against the rear surface). On the other hand, the other side of the base 111 can function as a fixed surface that is fixed to the outer surface of the pillar material.

As shown in FIG. 9(b), the pair of rails 115 are L-shaped protrusions extending in the front-rear direction of the base 111, extending substantially perpendicularly from the base 111 plane in front view and bending in a direction opposite to each other (up-down direction). The front and rear of the pair of rails 115 are open so that the plate-shaped connecting parts 131 can be inserted in a sliding manner. A notch 111c is formed on the side of the base 111 facing each rail 115. As described later, the pair of rails 115 are configured to hold the support 130 between the rails 115 and guide the sliding movement of the support 130 in the front-rear direction by inserting the connecting parts 131 of the support 130 between the opposing rails 115. Also, as shown in FIG. 9(c), a plurality of locking pieces 116 are formed on the leading edge of each rail 115 in front view. Each locking piece 116 is composed of a rear base end 116a connected to the tip edge of the rail 115, and a long and thin claw portion 116b extending forward from the base end 116a. The base end 116a extends substantially parallel to the plane of the base 111, and the claw portion 116b is inclined so as to approach the plane of the base 111. The claw portion 116b has a free end at its tip facing forward. As will be described later, the tip of the claw portion 116b is inserted into the locking hole 133 of the connecting portion 131 and is locked to the end face of the locking hole 133 as a restricting portion. In this embodiment, four locking pieces, a first locking piece 1161, a second locking piece 1162, a third locking piece 1163, and a fourth locking piece 1164, are formed in this order from the front side of the base 111. The first locking piece 1161 and the third locking piece 1163 are formed on the upper rail 115, and the second locking piece 1162 and the fourth locking piece 1164 are formed on the lower rail 115.

The addressing portion 112 is applied to the outer surface of the post material (construction material) to which it is fixed, and assists in the attachment of the base body 110. In particular, the addressing portion 112 is applied to a surface (front or rear surface) of the post material that is different from the direction in which the support arm portion 132 (or the main body of the installation body) extends. In addition, the addressing portion 112 is applied to a reference surface of an arbitrarily selected post material, so that the front position of the installation body 100 to be installed can be aligned to a position that is further back from the rear surface position of the front wall (see FIG. 14). In other words, the addressing portion 112 temporarily holds the base body 110 against the post material, and can also function as an alignment portion that determines the installation position of the installation body 100 based on the outer surface of the post material. In addition, the addressing portion 112 is designed to be compact with a vertical width that fits within the range of the vertical width of the box 101, which is the main body of the installation body.

The allocation portion 112 bends at a right angle from the front edge of the base 111 in the opposite direction to the extension direction of the support 130, and extends from the base end (on the base 111 side) to the tip. The allocation portion 112 consists of a rectangular long portion 113 located on the upper side in the vertical width direction and a rectangular short portion 114 located on the lower side. The long portion 113 has an extension length that exceeds half the width of the front surface of the pillar material to be allocated, and the short portion 114 has an extension length that does not exceed half the width of the front surface of the pillar material to be allocated. Both the long portion 113 and the short portion 114 extend at a position that is shifted from the vertical direction with respect to the reference position (center) of the vertical width of the box 101 and the support 130. Due to the relationship between the position and shape of the long portion 113 and the short portion 114, when two mounting bodies 100 are installed at the same height against one pillar material, the mounting portions 112 of the base body 110 can be mounted simultaneously on the same surface of the pillar material without interfering with each other (see FIG. 21). In other words, the mounting portions 112 are configured so that when the mounting portions 112, 112 of the two mounting bodies 100, 100 are mounted on the front surface of the pillar material, the mounting portions 112, 112 do not overlap with each other, and the main body portions (boxes 101, support bodies 130) of the two mounting bodies 100, 100 can be positioned at the same position in the height direction of the pillar material.

In addition, two types of screw holes 113a, 113b are provided in the long portion 113 of the fitting portion 112 as pilot holes for fixing screws. One of the two screw holes 113a, 113a is formed to be positioned at the width center of the pillar material having a first pillar width (e.g., 45 mm), and the other screw hole 113b is formed to be positioned at the width center of the pillar material having a smaller second pillar width (e.g., 40 mm). In other words, the screw holes 113a, 113a and the screw hole 113b are formed at positions offset in the height (vertical width) and horizontal (horizontal width) directions to accommodate the two types of pillar widths. This arrangement allows the fitting portion 112 to be stably attached to the pillar material.

Furthermore, the alignment portion 112 is provided with a mechanism for aligning the installation height of the installation body (reference position of the box 101 or the support arm portion 132). The alignment portion 112 of the base body 110 (fixed portion) is provided with a reference position display portion 117 that indicates the reference position 1012c (center) of the vertical width of the second form of box 1012 (see FIG. 20) in which the attachment portion 1012d and the reference position 1012c (center of the vertical width) are shifted in the height direction. As shown in FIG. 20, the reference position display portion 117 is formed by the lower edge of the alignment portion 112 (or the base body 110) and is determined according to the shape and dimensions of the box 1012. In other words, when the alignment portion 112 is aligned to the front or rear surface of the pillar material, the height position of the reference position display portion 117 and the center of the aligned box 1012 are the same. In addition, the fitting portion 112 of the base body 110 (fixed portion) is provided with a second reference position display portion 118 that indicates the reference position (center 101c) of the box 101 where the attachment portion (101d) is at the same height as the reference position (center 101c) of the vertical width. The second reference position display portion 118 is a notch provided at the tip edge at approximately the center of the vertical width direction of the fitting portion 112. As shown in FIG. 15, when the fitting portion 112 is fitted to the front surface of the pillar material, the height position of the second reference position display portion 118 is the same as the height of the reference position (center 101c) of the arranged box 101 and/or the support arm portion 132. The second reference position display portion 118 also functions as an attachment portion display portion that displays the height position of the attachment portion (101d) of the box 101.

The support 130 is a long plate that is L-shaped in plan view and extends from its base end to its tip. The support 130 is composed of a connecting part 131 located at its base end and fixed to the side of the construction material via the base part 111 (connected part) of the base body 110, and a support arm part 132 that extends longitudinally from the connecting part 131 to its tip (or the side of the pillar material). In other words, the support 130 is bent in an L shape, and the short piece-shaped connecting part 131 and the long piece-shaped support arm part 132 are connected at approximately right angles. The support arm part 132 has a vertical width direction perpendicular to the extension direction. The extension direction corresponds to the horizontal direction when the installation body 100 is installed on the construction material, and the vertical width direction corresponds to the vertical (perpendicular) direction when the installation body 100 is installed on the construction material.

The connecting portion 131 is made of a rectangular flat plate that is shorter than the support arm portion 132. The connecting portion 131 has a plurality of locking holes 133 drilled therein as part of the connecting mechanism. Each locking hole 133 is formed at a position where the locking piece 116 can be inserted when the connecting portion 131 is held between a pair of rails 115, 115 of the base portion 111 of the base body 110. The plurality of locking holes 133 are composed of two first locking holes 1331 located at the top and bottom on the front end side and two second locking holes 1332 located at the top and bottom on the rear end side. The first locking holes 1331 are round holes, and the second locking holes 1332 are long holes extending in the front and rear directions. The connecting portion 131 can be fixed to the side of the construction material by driving fixing screws into these locking holes 133, even if it is used alone.

The support arm 132 is made of a long rectangular flat plate, and is configured to extend away from the connecting portion 131 and support the box 101 on its front side. A plurality of long hole-shaped attachment holes 135 for fixing the box 101 are drilled in the center of the vertical width of the support arm 132. In addition, above and below the attachment holes 135, long holes extending in the width direction and long holes extending in the extension direction are formed, respectively. These long holes are not used to fix the box 101, but can be used when changing to another type of attachment body, such as a clip-shaped attachment body.

In other words, in the support device 102 of this embodiment, the base body 110 has an addressing portion 112 that is addressed to the wall fixing surface (front surface of the pillar material) of the construction material to which the wall material is fixed, and by addressing the addressing portion 112, the base portion 111 as the connected portion is positioned on the side of the surface that intersects with the wall fixing surface, and the support body 130 is assembled to the base body 110 so that the support arm portion 132 is spaced away from the side of the intersecting surface of the construction material.

The base body 110 and the support body 130 that constitute the support device 102 in this embodiment are obtained by bending and drilling SUS material, but the present invention is not limited to the manufacturing method and materials of one embodiment. For example, instead of metal materials such as SUS material, it is also possible to form the support device by molding hard resin, etc.

Next, the connecting mechanism that connects the base body 110 and the support body 130 will be described with reference to Figures 7 and 12. The connecting mechanism is a mechanism that is composed of the rail 115 and the locking piece 116 of the base body 110 (base portion 111) and the locking hole 133 of the support body 130 (connecting portion 131).

As shown in FIG. 7(a), the base body 110 and the support body 130 are connected by inserting the connecting portion 131 of the support body 130 between a pair of rails 115, 115 of the base body 110. The tip portions of the base 111 and the rail 115 sandwich the connecting portion 131 from the front and back, so that the connecting portion 131 is held by the base 111 (connected portion) so that it does not fall. The rail 115 guides the sliding of the support body 130 in the forward and backward directions by sandwiching the connecting portion 131 between them when the connecting portion 131 is connected to the base 111 (connected portion). Similarly, the locking piece 116 and the locking hole 133 (particularly the elongated second locking hole 1332) can guide the linear sliding of the support body 130 in the forward and backward directions.

7B, the tip of one of the locking pieces 116 is disposed in the locking hole 133. Since the locking piece 116 is inclined so as to have a free end on the front side, the movement of the connecting part 131 to the front side is not locked. In other words, the connecting mechanism allows the support body 130 to move relative to the base body 110 toward the front side. The support body 130 can move forward relative to the base body 110 until the surface of the support arm part 132 abuts against the rear end surface of the rail 115. On the other hand, when the support body 130 moves rearward relative to the base body 110, the locking piece 116 moves forward relative to the locking hole 133, and the claw part 116b of the locking piece 116 abuts against the front end surface of the locking hole 133 and is locked. In other words, the end surface of the locking hole 133 functions as a restricting part that restricts the support body 130 from moving rearward relative to the base body 110. Here, the one-to-one engagement between one locking piece 116 and one locking hole 133 restricts relative movement. This prevents the support 130 from moving rearward more than necessary and becoming detached from the base body 110. In other words, the connection mechanism allows the support 130 to be easily assembled by sliding it forward relative to the base body 110. Furthermore, after assembly, if the support 130 is slid relative to the base body 110 in the opposite direction to the mounting direction, the base body 110 and the support 130 are restricted from separating from each other.

Figure 12 illustrates an engagement pattern by the connecting mechanism of the base body 110 and the support body 130. Here, four stages of engagement patterns (one-to-one combinations of the locking piece 116 and the locking hole 133) are illustrated. Figure 12 (a) shows the connecting mechanism in the first engagement position where the first locking piece 1161 is engaged with the end face of the upper first locking hole 1331. After the first locking hole 1331 of the support body 130 slides forward from the first engagement position, the support body 130 is restricted from retracting from the first engagement position. The first engagement position shown in Figure 12 (a) is an engagement pattern that locks the support body 130 at the frontmost side (the state where it has moved the most in the direction approaching the wall material). Figure 12 (b) shows the connecting mechanism in the second engagement position where the second locking piece 1162 is engaged with the end face of the lower first locking hole 1331. After the first locking hole 1331 of the support 130 slides forward from the second engagement position, the support 130 is restricted from moving backward from the second engagement position. FIG. 12(c) shows the coupling mechanism in the third engagement position where the third locking piece 1163 is engaged with the end face of the upper second locking hole 1332. After the front end of the second locking hole 1332 of the support 130 slides forward from the third engagement position, the support 130 is restricted from moving backward from the third engagement position. FIG. 12(d) shows the coupling mechanism in the fourth engagement position where the fourth locking piece 1164 is engaged with the end face of the lower first locking hole 1331. After the first locking hole 1331 of the support 130 slides forward from the fourth engagement position, the support 130 is restricted from moving backward from the fourth engagement position. The fourth engagement position shown in FIG. 12(d) is an engagement pattern that locks the support 130 at the rearmost side. That is, in this embodiment, the restricting portion of the connecting mechanism makes it possible to gradually lock the support 130 that retreats relative to the base body 110. This more reliably prevents the support 130 from detaching backward from the base body 110. The combination of the fourth locking piece 1164 and the first locking hole 1331 ultimately functions as a blocking means that prevents the support 130 from detaching from the base body 110.

Next, referring to Figures 13 to 15, we will explain one embodiment of a support structure 11 in which an arrangement body 100 (box 101 and support device 102) is arranged on a pillar material 17, which is a construction material. Figure 13 is a schematic perspective view from the front of the support structure 11. Figure 14 is a plan view of the support structure 11. Figure 15 is a front view of the support structure 11.

The support structure 11 is a structure in which an arrangement 100 is supported on a pillar material 17. The support structure 11 includes a pillar material 17 arranged behind a wall, a support device 102 fixed to the pillar material 17 on the back side of the wall material (front wall 18), and a box 101 supported by the support device 102 in the space on the back side of the wall material. This support structure 11 is a structural portion that does not include wall material in front of and/or behind the pillar material 17, and the imaginary line in FIG. 14 indicates the position where the wall material (front wall 18) in the support structure 11 is constructed. In this embodiment, the front wall 18 is planned to be constructed at a position separated from the front surface of the pillar material 17.

In the support structure 11 of this embodiment, the base 111 of the base body 110 is fixed to the side of the pillar 17 (facing the box 101), and the fitting portion 112 is fixed to the front of the pillar 17. As shown in FIG. 14, the base 111 is fixed to the side of the pillar 17 by passing a fixing screw through the fixing hole 111a. In addition, the support body 130 is assembled to the base body 110 via a connecting mechanism. The support arm 132 extends horizontally in the extension direction of the pillar 17 so as to be spaced apart from the pillar 17 to the side. Note that here, the base 111 of the base body 110 is fixed to the side of the pillar 17 with a fixing screw using the fixing hole 111a, but instead, the fitting portion 112 of the base body 110 may be fixed to the front of the pillar 17 with a fixing screw using the screw hole 113a of the fitting portion 112. Alternatively, both the fixing hole 111a and the screw hole 113a may be used to fix the base 111 to the side of the pillar 17 and the fitting portion 112 to the front of the pillar 17.

The box 101 is attached to the support arm 132 at a predetermined position in the longitudinal direction with screws. Specifically, the attachment hole 101d of the box 101 as the attachment portion is aligned in the height direction and horizontal direction with the attachment hole 135 as the attachment portion, and is attached with screws. As shown in FIG. 15, in the support structure 11 of this embodiment, the center 101c (reference position) in the vertical width direction of the box 101 is at the same position in the height direction as the attachment hole 135 (attachment portion) of the support arm 132 and the attachment hole 101d (attachment portion) of the box 101. The second reference position display portion 118 formed on the allocation portion 112 indicates the height of the center 101c of the box 101.

In the support structure 11, the box 101 of the arrangement 100 is not fixed in the front-rear direction, but is movably supported by the support device 102. As shown in FIG. 14, a gap is formed between the front surface of the box 101 (arrangement body) and the back surface position of the front wall 18 (to be erected), and the support 130 is connected to the base body 110 in a state in which it is allowed to move in the approaching direction relative to the back surface position of the wall material. That is, in the support structure 11, the box 101 and the support 130 are positioned rearwardly away from the back surface position of the front wall 18, so that the box 101 and the support 130 do not interfere with the front wall 18 when erecting the front wall 18. In addition, after the front wall 18 is erected, the box 101 and the support 130 can be operated to move in the approaching direction to reliably abut the front surface of the box 101 against the back surface of the front wall 18.

Figure 16 shows an arrangement body installation structure 10 in which a plurality of pillar materials, including at least a first pillar material 17-1 and a second pillar material 17-2, are arranged in a staggered pattern at intervals, and a front wall 18 and a rear wall 19 are formed in front and behind the first pillar material 17-1 and the second pillar material 17-2, and two arrangement bodies 100, 100' are arranged on the structure. That is, the arrangement body installation structure 10 includes a front wall 18 having a wall surface on the front side, a rear wall 19 facing the front wall 18 at a distance and having a wall surface on the rear side, a first pillar 17-1 abutting the back surface of the front wall 18 in the back-wall space between the front wall 18 and the rear wall 19 and standing apart from the rear wall 19, a second pillar 17-2 abutting the back surface of the rear wall 19 in the back-wall space and standing apart from the front wall 18, and first and second arrangement bodies 100, 100' arranged at predetermined positions in the back-wall space and having a front surface facing the front wall 18. Here, the first arrangement body 100 has a structure similar to the arrangement body 100 described above, but the second arrangement body 100' has a structure partially different from the arrangement body 100 described above in terms of a connecting mechanism. In addition, furring strips may be interposed between the front wall 18 and the first pillar material 17-1, and/or between the rear wall 19 and the second pillar material 17-2. In this case, since the furring strips are interpreted as part of the wall material or pillar material, it can be said that the front wall 18 and the first pillar material 17-1 (the rear wall 19 and the second pillar material 17-2) are abutted via the furring strips.

With regard to the first arrangement body 100 of the arrangement body installation structure 10, the first arrangement body 100 is fixed to the second pillar material 17-2 with the front surface of the first arrangement body 100 aligned at a position further rearward than the rear surface position of the front wall 18. At this time, the arrangement body 100 is positioned in the front-to-rear direction by the alignment portion 112 being aligned to the front surface of the second pillar material 17-2 as an alignment portion. In other words, the arrangement position of the first arrangement body 100 is determined based on the front surface of the second pillar material 17-2. With this arrangement body 100, the support body 130 is allowed to move closer to the front wall 18.

On the other hand, the second arrangement 100' of the arrangement installation structure 10 is fixed to the first pillar 17-1 with the front surface of the second arrangement 100' aligned to a position further rearward than the rear surface of the front wall 18. At this time, the arrangement 100' is positioned in the front-rear direction by the alignment portion 112 being aligned to the rear surface of the first pillar 17-1 as an alignment portion. In other words, the arrangement position of the second arrangement 100' is determined based on the rear surface of the first pillar 17-1. In this arrangement 100', the support 130 is allowed to move closer to the front wall 18. The connection mechanism of the second arrangement 100' is configured so that the free end of the engagement piece faces in the opposite direction to the front-rear direction with respect to the base body 110 in Figures 8 and 9.

17 shows a front view of the first arrangement 100 in a state in which the device I is attached to the arrangement installation structure 10 in FIG. 16. That is, in the arrangement installation structure 10 in FIG. 17, the device I is attached to the arrangement 100. Here, the device I is a wiring device such as an outlet cover or a switch, but is depicted diagrammatically in the drawing. In the arrangement installation structure 10 of this embodiment, two wall holes 18a are drilled at predetermined positions in the front wall 18, and as shown in FIG. 17, the center 101c (reference position) of the box 101 is aligned with the center of each wall hole 18a. Then, the box 101 faces the wall surface through the wall holes 18a. At this time, the front surface of the flange 101a of the box 101 abuts against the back surface of the front wall 18 without any gaps over the entire circumferential direction. Furthermore, the device I is attached to the box 101 through the device mounting portion 101b of the box 101 and the mounting screw (screw). The fastening force of the mounting screw clamps the periphery of the wall hole 18a of the front wall 18 between the fixture I and the flange 101a. That is, in the installation structure 10, the front surface of the box 101 is securely abutted against the back surface of the front wall 18, providing a shielding effect that leads to sound insulation and fire resistance. Although not shown, the second installation 100' in which the fixture I is installed is similar to the first installation 100.

Next, referring to FIG. 18, we will explain how to install the first mounting body 100 on the second pillar material 17-2 to construct the mounting body installation structure 10 and install the device I.

First, in order to determine the placement position of the front of the box 101 at a position set back in the front-rear direction from the back surface position of the front wall 18 (to be erected), the reference surface of the pillar material to which the alignment portion (allocation portion 112) of the base body 110 is to be aligned is determined, taking into consideration the front-rear width of the box 101 (or the arrangement body 100). In this method, the front surface of the second pillar material 17-2 is selected as the reference surface. Next, based on the installation height of the device I (center position), a scribing line is formed on the outer surface (preferably the front surface) of the second pillar material 17-2. Then, the alignment portion (allocation portion 112) is abutted against the reference surface of the second pillar material 17-2, and the front surface of the arrangement body 100 is aligned at a position rearward of the back surface position of the front wall 18.

Next, as shown in FIG. 18(a), the base body 110 is fixed to the second pillar 17-2 at a predetermined height position according to the marking line of the second pillar 17-2. In this process, the user can easily hold the base body 110 in place by placing the addressing portion 112 of the base body 110 on the front surface of the second pillar 17-2 and pressing the addressing portion 112 against the second pillar 17-2 from the wall surface with his or her hand. In particular, since the long portion 113 of the addressing portion 112 has an extension length that exceeds half the width of the front surface of the pillar 17-2, the task of addressing the addressing portion 112 to the front surface of the pillar 17-2 is easy. In addition, by aligning the second reference position display portion 118 with the marking line, the center 101c (reference position) of the box 101 can be aligned to the desired height position (the center position of the instrument I or the wall hole 18a). Then, the base body 110 is fixed to the second pillar 17-2 as a fixed part by driving a fixing screw into the fixing hole 111a of the base 111. With the base body 110 fixed to the second pillar 17-2, the connecting part 131 of the support body 130 is inserted from rear to front between the pair of rails 115 of the base 111, so that the support body 130 is assembled to the base body 110. At this time, the insertion amount is adjusted according to the front-to-rear width of the box 101 so that the front position of the box 101 is at least behind the rear position of the front wall 18 to be erected. By determining the position of the support arm 132 as far forward as possible, the amount of movement in the space behind the wall can be reduced. That is, with the arrangement 100 of this embodiment, when the base body 110 as the fixing part is fixed to the second pillar material 17-2, the height position of the reference position of the arrangement 100 (center 101c of the box 101) and the front-to-rear position of the front of the arrangement 100 (front of the box 101) can be adjusted to the desired positions.

In the next step, the box 101 is fixed with screws to a predetermined position in the extension direction of the support arm 132. At this time, the attachment hole 135 (attached part) in the center of the vertical width of the support arm 132 and the attachment hole 101d (attachment part) of the box 101 are aligned and fixed with screws. This positions the reference position of the box 101 at the same height as the scoring line, and the support structure 11 of the arrangement 100 is constructed.

In the next step, as shown in FIG. 18(b), the front wall 18 is constructed so that its back surface abuts against the front surface of the first pillar 17-1, and the rear wall 19 is constructed so that its back surface abuts against the rear surface of the second pillar 17-2. A wall hole 18a is drilled in the front wall 18, with its center at the same height as the scribed line. The tool mounting part 101b on the front side of the box 101 is exposed to the wall surface through the wall hole 18a. Next, as shown in FIG. 18(b), a mounting screw is passed through the mounting hole of the tool I from the wall surface and screwed into the tool mounting part 101b of the box 101.

Then, from the state shown in FIG. 18(b), the mounting screw is screwed in so as to move the support 130 together with the box 101 closer to the front wall 18. Then, as shown in FIG. 18(c), the mounting screw is tightened so that the flange 101a of the box 101 and the device I clamp the front wall 18. This allows the flange 101a of the box 101 to be in close contact with the back surface of the front wall 18, and the installation structure 10 can be constructed with the wall hole 18a sealed. Note that in the method of this embodiment, the installation body 100 is installed on the second pillar material 17-2, and then the front wall 18 and rear wall 19 are constructed. However, even after at least the front wall 18 is constructed, the installation body 100 can be arranged on the second pillar material 17-2 by utilizing the space (gap) between the front wall 18 and the front surface of the second pillar material 17-2.

19(a)-(c) show the steps of a method for constructing an installation structure 10 by installing the second installation body 100' on the first pillar material 17-1 and installing the instrument I. In this method, in order to determine the placement position of the front of the box 101 at a position set back in the front-rear direction from the rear surface position of the front wall 18 (to be erected), the reference surface of the pillar material to which the alignment portion (appointment portion 112') of the base body 110' is applied is determined, taking into account the front-rear width of the box 101 (or the second installation body 100'). In this method, the rear surface of the first pillar material 17-1 is selected as the reference surface. Next, a score line is formed on the outer surface (preferably the rear surface) of the first pillar material 17-1 based on the installation height of the instrument I (center position). Then, the alignment portion (the alignment portion 112') is brought into contact with the reference surface of the first pillar 17-1, and the front surface of the arrangement 100' is aligned to a position rearward of the rear surface position of the front wall 18. The subsequent steps are the same as those in the method for the first arrangement 100. Note that in the method of this embodiment, the arrangement 100 is installed on the first pillar 17-1, and then the front wall 18 and rear wall 19 are constructed, but even after at least the front wall 18 is constructed, the arrangement 100 can be arranged on the first pillar 17-1 by utilizing the space (gap) on the rear side of the first pillar 17-1.

That is, the method of the present invention can be expressed as follows based on the above embodiment.

(1) In a structure having a front wall having a wall surface on the front side, a rear wall facing the front wall at a distance and having a wall surface on the rear side, a first pillar member abutting the back surface of the front wall in a wall-back space between the front wall and the rear wall and standing apart from the rear wall, and a second pillar member abutting the back surface of the rear wall in the wall-back space and standing apart from the front wall, the method comprises installing an installation body at a predetermined position in the wall-back space before at least one of the walls is installed, with the front surface facing the front wall,
The mounting body includes an alignment unit that determines the mounting position of the mounting body using the rear surface of the first pillar as a reference surface for alignment, or an alignment unit that determines the mounting position of the mounting body using the front surface of the second pillar as a reference surface for alignment,
A step of positioning the alignment portion against the reference surface, and positioning the front surface of the arrangement body at a position rearward of the rear surface position of the front wall by applying the alignment portion to the reference surface of the pillar material;
The method further includes a step of fixing the mounting body to a pillar material that serves as the reference surface.

(2) A method of installing an installation body on a lateral side of a pillar material that is disposed in a back space of a front wall having a wall surface on the front side and abuts against the back surface of the front wall, with the front surface facing the front wall, comprising:
The arrangement includes an arrangement body and a support device that supports the arrangement body and is fixed to the pillar, the support device including an alignment section that determines a front-rear direction arrangement position of the arrangement body relative to the pillar using a rear surface of the pillar as a reference plane,
a step of positioning the front surface of the installation body to a position rearward of a rear surface position of the front wall by placing the positioning portion against the reference surface;
A step of fixing the mounting body to the pillar material;
The method includes a step of forming a through hole (wall hole) in the front wall erected on the front surface of the arrangement body to expose a portion of the front surface of the arrangement body to the wall surface, and sliding the arrangement body forward through the through hole until the arrangement body reaches the rear surface position of the front wall.

The following describes the effects of the arrangement installation structure 10 (or arrangement 100) according to one embodiment of the present invention.

According to the arrangement body installation structure 10 of this embodiment, the arrangement position of the arrangement body 100 can be determined by the alignment portion (alignment portion 112) in the first arrangement body 100 based on the front surface of the second pillar material 17-2 as a reference, and the front surface of the arrangement body 100 can be aligned to a position rearward of the rear surface position of the front wall 18. In other words, the arrangement body installation structure 10 of this embodiment does not align the arrangement body 100 based on the front surface of the first pillar material 17-1 against which the front wall 18 abuts, but aligns the arrangement body 100 based on the second pillar material 17-2 against which the rear wall 19 on the side against which the front surface of the arrangement body 100 does not face is abutted. Therefore, even when the front wall 18 is erected, it is possible to easily position the arrangement body 100 forward and backward by utilizing the gap.

In addition, in the second arrangement body 100', the arrangement position of the arrangement body 100 can be determined based on the rear surface of the first pillar material 17-1 by the alignment section (alignment section 112), and the front surface of the arrangement body 100 can be aligned to a position further rearward than the rear surface position of the front wall 18. That is, the arrangement body installation structure 10 of this embodiment does not align the arrangement body 100 based on the front surface of the first pillar material 17-1 on which the front wall 18 is formed, but aligns the arrangement body 100 based on the rear surface of the first pillar material 17-1, so that even when the front wall 18 is erected, it is possible to easily position the arrangement body 100 front to back by utilizing the gap.

The present invention is not limited to the above embodiment, and various embodiments and modifications may be made within the technical scope of the present invention. In other embodiments, components that share the same last two digits of the reference number have the same or similar characteristics, unless otherwise specified, and some of the descriptions thereof will be omitted.

(1) The present invention is not limited to the above embodiment and can take various forms. The support structure using the support device 102 of the above embodiment can take various forms, such as the support structures 21 and 31 shown in Figures 20 and 21. In other words, the support device of the present invention can be used in response to various situations. In the support structures 21 and 31 shown in Figures 20 and 21, the fixing screw passes through the screw hole 113a instead of the fixing hole 111a, thereby fixing the fitting portion 112 to the front surface of the pillar material 17, thereby fixing the support device 102 to the pillar material 17.

(2) The present invention is not limited to the above embodiment, and can take various forms. Figure 22 shows an arrangement (support device 402) of another embodiment of the present invention. The support device 402 is configured as a longitudinal flat plate, and includes a short fixed portion 410 on the base end side and a long support arm portion 432 extending adjacent to the fixed portion 410 (base portion 411). Here, in the arrangement of this embodiment, the fixed portion 410 is defined as the alignment portion. Figure 23 shows an arrangement installation structure 40 in which the arrangement (support device 402) is installed on a pillar material 17. In the arrangement installation structure 40, the rear surface of the pillar material 17 is defined as the reference surface, the fixed portion 410 as the alignment portion is assigned to the rear surface of the pillar material 17, and the arrangement is aligned so that the front surface of the arrangement (front surface of the box 401) is behind the wall material 18.

(3) The present invention is not limited to the above embodiment and may take various forms. In the above embodiment, the alignment is performed by applying the application part as an alignment part to the front or back surface of the pillar material, but the present invention is not limited to this. For example, only the support body 130 shown in FIG. 10 may be used for the arrangement. When the front surface of the second pillar material is the reference surface, the front edge or front end face of the connection part 131 is aligned with the front position (front edge of the side surface) of the second pillar material as an alignment part when the connection part 131 of the support body 130 is applied to the side surface of the second pillar material. Also, when the rear surface of the first pillar material is the reference surface, the rear edge of the connection part 131 of the support body 130 or the rear surface of the support arm part 132 is aligned with the rear surface position (rear edge of the side surface) of the first pillar material as an alignment part when the connection part 131 of the support body 130 is applied to the side surface of the first pillar material.

(4) The present invention is not limited to the above embodiment and may take various forms. In the above embodiment, the support device is configured to be fixed to the construction material in a cantilevered state via the fixing portion, but the present invention is not limited to this. For example, as shown in FIG. 24, the support device 202 may be configured to be provided with fixing portions (base body 210, connecting portion 231) on both ends of the support arm 232, and the support device 202 may be configured to be fixed between two columnar construction materials in a cantilevered state.

(5) The present invention is not limited to the above embodiment, and can take various forms. In the above embodiment, the locking piece of the connecting mechanism is provided on the base body, and the locking hole is provided on the support body, but the two may be provided in the opposite order.

(6) The present invention is not limited to the above embodiment, and may take various forms. In the above embodiment, the locking piece of the connecting mechanism abuts against the end face of the locking hole, thereby acting as a detent for the support body to return backward relative to the base body. However, this detent may be omitted, and the connecting mechanism may support the support body so that it can slide relative to the base body in both directions, toward and away from the wall material.

(7) The present invention is not limited to the above embodiment and can take various forms. In the above embodiment, the relative movement is restricted by the one-to-one engagement relationship between one locking piece and one locking hole of the connecting mechanism, but multiple locking pieces and multiple locking holes may be designed to act simultaneously.

(8) The present invention is not limited to the above embodiment and may take various forms. In the above embodiment, one mounting body (box) is arranged on one support or support arm, but multiple mounting bodies (e.g., boxes 101, 1012) of the same shape or different shapes may be attached to one support or support arm.

The present invention is not limited to the above-described embodiments and modifications, but may be implemented in various forms within the scope of the present invention.
