Abstract
Description
[Technical Field]
[0001] The present invention relates to a fixture that is fixed to the surface of a foam insulation layer of a wall, and also to a wiring / piping material holder device that installs wiring / piping material on the installation surface of a wall. [Background technology]
[0002] Conventionally, various fixtures, including boxes, wiring and piping holders, and their bases, are fixed to the installation surface of building walls. In particular, walls may be composed of a base wall and a foam insulation layer. In such cases, the fixtures must be fixed to the surface of the foam insulation layer without excessively crushing the foam insulation layer.
[0003] For example, Patent Document 1 discloses a wiring box and a box abutment as fixed bodies to be fixed to the installation surface of a structure. In the following paragraphs, the reference symbols of Patent Document 1 are shown in parentheses. A wiring box (10) is attached and fixed to a concrete wall (26) with fixing nails (23) with a heat insulating material (27) interposed between the wiring box (10) and the concrete wall (26). The box abutment (24) is cylindrically formed from a synthetic resin material. The fixing nails (23) can be inserted axially into the box abutment (24). The following describes a method for attaching a wiring box (10) to a concrete wall (26) with a heat insulating material (27) interposed between the rear side of the wiring box (10) and the concrete wall (26) as a structure. The heat insulating material (27) is fixedly disposed on one side of the concrete wall (26) as a structure, and two through-holes (28) are formed through the heat insulating material (27). The through holes 28 correspond to the mounting portions 22 formed at the upper and lower ends of the back surface of the wiring box 10. One end of each box abutment 24 is then snapped off so that the axial length of the box abutment 24 and the thickness of the insulation 27 are approximately equal. The mounting portions 22 located at the upper and lower ends of the wiring box 10 are then aligned with each box abutment 24. The fixing nails 23 are then inserted into the box abutment 24 through the insertion holes 21, and the box abutment 24 guides the fixing nails 23 perpendicular to the concrete wall 26. The heads 23a of the fixing nails 23 are then struck with a hammer or the like to drive the tips of the fixing nails 23 into the concrete wall 26, and the heads 23a of the fixing nails 23 are then placed in the recesses 20. Then, the other end of the box abutment body 24 protruding from the surface of the insulating material 27 engages with the mounting portion 22 and abuts against the back surface of the wiring box 10. As a result, the wiring box 10 is attached and fixed to the concrete wall 26 with the insulating material 27 interposed between the wiring box 10 and the concrete wall 26.At this time, the pair of box abutments 24, each having a length approximately equal to the thickness of the insulating material 27, secures the wiring box 10 to the concrete wall 26 while maintaining a distance equal to the thickness of the insulating material 27. As a result, the back surface of the wiring box 10 is prevented from pressing against the insulating material 27 when the fixing nails 23 are driven in, and the insulating material 27 is prevented from being compressed and deformed.

[0005] With the fixing body (wiring box and / or box abutment) of Patent Document 1, after inserting the box abutment into the foam insulation layer (thermal insulation) and aligning the wiring box to the fixing position, it is necessary to maintain the posture and position of the wiring box with one hand while operating the fixing nail and tool (hammer or screwdriver) to drive the fixing nail with the other hand. In particular, it is difficult to handle the fixing nail and tool simultaneously with one hand, which makes the workability poor.

[Effects of the Invention]
[0019] According to the fixture described in claim 1, the fixture has an insertion tube portion protruding in the axial direction from the back side of the main body portion. The tip of the insertion tube portion has a tapered surface inclined relative to the axial direction so as to form a tapered shape from the axial portion to the tip. This press-fit guide portion guides the insertion tube portion into the foam insulation layer when pressed. This allows the fixture to be easily positioned on the surface of the foam insulation layer when the back side of the fixture is pressed toward the foam insulation layer. The fixture also has a temporary attachment portion that, when pressed into the foam insulation layer, creates a temporary attachment state that prevents the fixture from falling off the foam insulation layer due to at least its own weight. This allows the user to easily fix the fixture to the wall by inserting and driving a screw into the insertion channel formed in the insertion tube portion from the surface side of the wall without holding the fixture by hand, using a screw and a tool. Therefore, the fixture of the present invention improves the workability of fixing the fixture to the surface of the foam insulation layer of the wall.
[0020] According to the fixed body described in claim 2, in addition to the effect of the invention of claim 1, the cylindrical wall of the press-fit guide portion becomes gradually thinner toward the tip, so that it is possible to form a press-fit guide portion with a tapered surface at the tip of the insertion cylindrical portion while ensuring the diameter of the insertion path through which the screw is inserted.
[0021] According to the fixture described in claim 3, in addition to the effects of the inventions of claims 1 and 2, a dam portion is formed with a plate-shaped receiving surface facing the insertion tube portion in the radial direction. As a result, when the insertion tube portion is press-fitted into the foam insulation layer, the receiving portion acts to receive the foam insulation layer, which deforms and expands in the radial direction of the insertion tube portion (perpendicular to the axial direction of the tube). In other words, deformation of the foam insulation layer in the direction away from the insertion tube portion in the radial direction due to press-fitting of the insertion tube portion into the foam insulation layer can be reduced. As a result, a compressed region is formed in the foam insulation layer between the receiving portion and the insertion tube portion, which improves the pressure contact force between the insertion tube portion and the foam insulation layer and contributes to maintaining the temporary attachment state.
[0022] According to the fixed body described in claim 4, in addition to the effects of the invention of claim 3, by arranging multiple dam portions to surround the periphery of the insertion tube portion, it is possible to control the deformation of the foamed insulation layer around the insertion tube portion and effectively improve the pressure contact force.
[0023] According to the fixing body described in claim 5, in addition to the effects of the invention of claim 1 or 2, when the insertion tube portion is pressed into the pilot hole of the screw formed in the foam insulation layer, the temporary attachment portion is pressed against the foam insulation layer, thereby effectively forming a temporary attachment state.
[0024] According to the fixture described in claim 6, in addition to the effects of the invention of claim 1 or 2, when the insertion part serving as a temporary attachment part is pressed into the foam insulation layer, resistance is generated when the tip of the sensing part abuts the surface of the foam insulation layer, allowing the user to sense that the insertion part has been inserted into the foam insulation layer beyond the required insertion length. The user can stop pressing the insertion part into the foam insulation layer at the appropriate time and carefully drive the screws thereafter, preventing the fixture from crushing the foam insulation layer too much.
[0025] According to the fixed body described in claim 7, in addition to the effects of the invention of claim 1 or 2, the abutment portion extends on the same plane and more than half of the area of the back surface of the main body portion is recessed below the abutment portion, so that even if the abutment portion digs into the surface of the foamed insulation layer, the deformed foamed insulation layer escapes into the recess on the back surface of the main body portion, thereby reducing the amount of crushing of the foamed insulation layer.
[0026] According to the wiring and piping material holder device of claim 8, by using the fixed body and the wiring and piping material holder in combination, the effect of the invention of claim 1 can be achieved as a wiring and piping material holder device. Furthermore, the temporary screw holding portion temporarily holds the screw inserted into the insertion path, eliminating the need for the user to hold the screw by hand. Furthermore, the temporary attachment portion can maintain a temporary attachment state by suspending the wiring and piping material holder on the screw temporarily held by the temporary screw holding portion and inserted into the fixing portion. This allows the user to easily fix the wiring and piping material holder device to a wall by operating a tool without having to hold the wiring and piping material holder device and screws by hand. Therefore, the wiring and piping material holder device of the present invention improves the workability of wiring and piping material installation work on a wall.
[0027] According to the wiring / piping material holder device of claim 9, by using a fixed body and a wiring / piping material holder in combination, the effect of the invention of claim 1 can be achieved as a wiring / piping material holder device. Furthermore, the temporary screw holding portion temporarily holds the screw inserted into the insertion path, eliminating the need for the user to hold the screw by hand. Furthermore, the fixed body and wiring / piping material holder can be assembled to each other, and the temporary attachment portion can maintain a temporary attachment state when the fixed body and wiring / piping material holder are assembled. This allows the user to easily fix the wiring / piping material holder device to a wall by operating a tool, without having to hold the wiring / piping material holder device and screws by hand. Therefore, the wiring / piping material holder device of the present invention improves the workability of wiring / piping material installation work on a wall.
[0028] According to the wiring and piping material holder device of claim 10, the fixed body is provided with a temporary attachment portion that allows the fixed body to be temporarily attached to the installation surface while the back side of the fixed body is abutted against the installation surface to prevent it from falling off the installation surface due to its own weight. Furthermore, the temporary screw holding portion temporarily holds the screw inserted into the insertion path, eliminating the need for the user to hold the screw by hand. The wiring and piping material holder is placed in an installation area formed on the front side of the fixed body, and is fixed to the installation surface together with the fixed body by the inserted screw via the fixing portion. At this time, the temporary attachment portion allows the wiring and piping material holder to be temporarily attached while hanging from the screw temporarily held by the temporary screw holding portion. This allows the user to easily fix the wiring and piping material holder device to the installation surface of a wall by operating a tool without having to hold the wiring and piping material holder device and screws by hand. Therefore, the wiring and piping material holder device of the present invention improves the workability of wiring and piping material installation work on installation surfaces.
[0029] According to the wiring and piping material holder device described in claim 11, in addition to the effect of the invention of claim 10, when the installation surface of the wall is set on the surface of the foam insulation layer, the insertion portion as a temporary attachment portion is pressed against the installation surface from the surface side of the wall and inserted into the foam insulation layer, making it possible to easily form a temporary attachment state by pressing the insertion portion against the foam insulation layer.
[0030] According to the wiring and piping material holder device described in claim 12, in addition to the effects of the inventions of claims 8, 9 and 11, the area facing the surface of the foam insulation layer on the back side of the fixed body is larger than the contact area of the wiring and piping material holder abutting against the placement area, so the crushing resistance to the foam insulation layer is greater than when the wiring and piping material holder is fixed directly to the surface of the foam insulation layer, making it easier to sense when the foam insulation layer is starting to crush, and making it possible to stop driving in screws before the foam insulation layer is crushed too much.

[0032] An embodiment of the present invention will be described below with reference to the drawings. The shapes of the drawings referred to in the following description are conceptual or schematic diagrams for explaining preferred shapes and dimensions, and the dimensional ratios do not necessarily correspond to the actual dimensional ratios. In other words, the present invention is not limited to the dimensional ratios shown in the drawings. Furthermore, the up, down, left, and right directions in the present invention are merely concepts indicating relative positions, and needless to say, these directions can be interchanged and applied.
[0033] [Fixed body] The fixed body 110 of one embodiment of the present invention is fixed to the installation surface of the wall 11, either alone or in combination with other fixtures. That is, the fixed body 110 may be configured to have some functionality, such as a wiring and piping material holder or a wiring box function, or may be configured to be fixed to the installation surface of the wall together with other fixtures having desired functionality to assist in the installation of the fixtures on the installation surface. In this embodiment, the fixed body 110 is fixed to an installation surface defined on the surface of the foam insulation layer 15 of the wall 11 together with a wiring and piping material holder 130, and is used to install wiring and piping materials 17. Here, in this embodiment, the wall 11 is composed of a base wall 13 and a foam insulation layer 15 that form a ceiling, as shown in FIG. 4 , and the installation surface is defined on the downward-facing surface of the foam insulation layer 15. However, the fixed body 110 of this embodiment is not limited to this application and may be used for other applications. Below, each component of the fixed body 110 of the present invention is described.
[0034] First, the configuration of a fixed body 110 according to one embodiment of the present invention will be described with reference to Figures 1 to 3. Figures 1(a) and 1(b) are perspective views of the fixed body 110. Figures 2(a) to 2(d) are front, rear, plan, and side views of the fixed body 110. Figures 3(a) and 3(b) are AA and A'-A' cross-sectional views of the fixed body 110.
[0035] As shown in FIGS. 1 to 3 , the fixed body 110 includes a main body 111, an insertion tube 113 protruding from the rear surface of the main body 111 in the axial direction, a plurality of dam portions 117 protruding from the rear surface of the main body 111 so as to surround the insertion tube 113, and a sensing portion 118 disposed protruding further toward the rear surface than the abutting portion 112 of the main body 111 and protruding less than the insertion tube 113 and the dam portions 117. The fixed body 110 is preferably integrally molded from a rigid synthetic resin material. The fixed body 110 is provided with a temporary attachment portion that, when the insertion tube 113 is press-fitted into the foamed insulation layer 15, prevents the fixed body 110 from falling off the foamed insulation layer 15 due to at least its own weight (preferably including the weight of the screw and / or wiring / piping material holder 130). Here, when the fixing body 110 is pressed from the wall surface side against the surface of the foamed insulation layer 15, the insertion portion that is mainly inserted into the foamed insulation layer 15 is the insertion tube portion 113 and the dam portion 117 that extend in the axial direction from the back surface side of the main body portion 111. A temporary attachment portion can be formed in at least a part of the insertion portion (mainly the tube shaft portion 114 of the insertion tube portion 113).
[0036] The main body 111 has a front surface and a back surface and is a rectangular plate extending in a planar direction. Here, the front surface of the main body 111 faces the front side of the wall 11 when fixed to the wall 11, and the back surface faces the surface of the wall 11. The main body 111 is configured to be fixed to the wall 11 with its back surface abutting against the surface of the foamed insulation layer 15 (as the installation surface). The main body 111 has an abutment portion 112 on its back surface that abuts against the surface of the foamed insulation layer 15. This abutment portion 112 is defined by the tip surface of a flange that rises from the back surface at the outer periphery of the main body 111. The abutment portion 112 extends on the same plane, and more than half of the area of the back surface of the main body 111 is recessed relative to the abutment portion 112. On the other hand, the surface of the main body 111 is provided with an arrangement area 111a in which a device (wiring / piping material holder 130) with desired functionality is arranged. In this embodiment, the placement area 111a includes lines for aligning the base 131 of the wiring / piping material holder 130, as shown in Fig. 2. As will be described later, the placement area 111a allows the wiring / piping material holder 130 to be aligned and placed in two different placement orientations (see Figs. 15 and 16).
[0037] The insertion tube portion 113 is a hollow cylindrical body extending approximately vertically from the center position of the back surface of the main body portion 111, and has openings at the base end and the tip end through which screws pass. The insertion tube portion 113 extends along a cylindrical axis direction perpendicular to the plane of the main body portion 111 (or the same plane on which the abutment portion 112 extends).
[0038] The insertion tube portion 113 includes a tube shaft portion 114 extending in the tube axial direction from its base end toward the tip end, a press-fit guide portion 115 connected to the tip end of the tube shaft portion 114, and having a tapered surface inclined with respect to the tube axial direction so as to form a tapered shape distal to the tube shaft portion 114, and guiding the insertion of the insertion tube portion 113 into the foamed insulation layer 15 by press-fitting, and an insertion path 116 penetrating the insertion tube portion 113 (and the fixed body 110) along the entire tube axial direction and into which a screw is inserted to be driven from the surface side of the main body portion 111. In this embodiment, the length of the tube shaft portion 114 in the tube axial direction is greater than the length of the press-fit guide portion 115 in the tube axial direction. The tube shaft portion 114 has an axial length and an outer diameter that allow it to be press-fitted temporarily against the foamed insulation layer 15 when the insertion tube portion 113 is press-fitted into the foamed insulation layer 15 (through the pilot hole 12 for the screw). That is, in this embodiment, a temporary attachment portion is defined on at least a part of the outer surface of the cylindrical shaft portion 114 having a predetermined outer diameter.
[0039] As shown in FIG. 3, the tapered surface of the press-fit guide portion 115 is inclined at a larger angle relative to the cylindrical axis direction than the cylindrical shaft portion 114. In this embodiment, the cylindrical shaft portion 114 may have the same diameter along the entire cylindrical axis direction, but may be configured to increase in diameter toward the base end at a gentler angle than the tapered surface of the press-fit guide portion 115 (see FIG. 23). In this embodiment, the insertion path 116 may have the same diameter along the entire cylindrical axis direction, but may be configured to gradually decrease in diameter toward the tip (see FIG. 23). In this embodiment, the cylindrical shaft portion 114 and the insertion path 116 are configured to have the same diameter continuously along the cylindrical axis direction, so that the press-fit guide portion 115 is formed on the outer surface of the tip portion of the cylindrical wall, which is gradually thinned toward the tip. At the tip of the insertion cylindrical portion 113, the outer diameter of the press-fit guide portion 115 at the tip is approximately equal to the diameter of the insertion path 116 (the inner diameter of the cylindrical wall). That is, the outer diameter of the tip of the insertion tube portion 113 is small, making it easy to insert into the foam insulation layer 15. In addition, it is preferable that the diameter of the outer surface of the tip of the press-fit guide portion 115 be set to within 110% of the maximum diameter of the screw. This prevents the screw from rattling inside the insertion path 116.
[0040] Furthermore, the main body 111 is provided with a temporary screw holding portion 119 that temporarily holds a screw inserted into the insertion path 116. The temporary screw holding portion 119 is formed by a substantially rectangular hole that communicates with the insertion path 116 and is smaller than the cross-sectional shape (perpendicular to the cylindrical axis) of the insertion path 116. The temporary screw holding portion 119 is large enough to allow a screw to be press-fitted and inserted therein, and is configured to temporarily hold the screw. That is, the user can insert the tip of a screw shank into the insertion path 116, causing the temporary screw holding portion 119 to temporarily hold the screw in the fixed body 110. In this embodiment, the temporary screw holding portion 119 is formed at the end of the insertion path 116, but it may also be formed at a location midway along the insertion path 116 (see FIG. 23 ) or at an adjacent location outside the insertion path 116.
[0041] The dam portion 117 is a thin plate-like member having a leading edge and protruding from the rear surface of the main body portion 111. The dam portion 117 is configured to bite into the foamed insulation layer 15 from its leading edge when the insertion tube portion 113 is press-fitted into the foamed insulation layer 15. In other words, the dam portion 117 extends along the axial direction of the tube, approximately parallel to the insertion tube portion 113. The dam portion 117 is plate-shaped and has a receiving surface 117a that faces the outer peripheral surface of the insertion tube portion 113 from the radially outside. A plurality of dam portions 117 are arranged around the periphery of the insertion tube portion 113. In this embodiment, four dam portions 117 are arranged diagonally opposite each other around the main body portion 111. As will be described later, the dam portion 117 functions to reduce deformation of the foamed insulation layer 15 in a direction radially away from the insertion tube portion 113 when the insertion tube portion 113 is pressed into the foamed insulation layer 15 (see Figures 7(b) and 8). The multiple dam portions 117 also function as anti-rotation devices that restrict rotation of the fixed body 110 around the insertion tube portion 113 inserted into the foamed insulation layer 15.
[0042] The sensing portion 118 is formed as a rib (or rib tip surface) that protrudes from the back surface of the main body portion 111. The rib extends diagonally on the back surface of the rectangular main body portion 111 and is connected to the flange (contact portion 112), the insertion tube portion 113, and the dam portion 117, reinforcing the structure of the fixed body 110. The tip surface of the rib forms an inclined surface so that the amount of protrusion toward the back surface increases as it approaches the insertion tube portion 113 (center). Furthermore, the tip surface of the rib is formed narrow so that it bites into the foam insulation layer 15 when pressed against it.
[0043] The sensing portion 118 is formed to protrude further toward the back side than the abutting portion 112 of the main body portion 111, and is capable of sensing that the insertion portion (at least the insertion tube portion 113) has been inserted into the foam insulation layer 15 to an insertion length greater than that required for the insertion portion to function as a temporary attachment portion. In particular, the sensing portion 118 is positioned closer to the back side of the main body portion 111 than the tip of the insertion portion, and the distance in the axial direction between the sensing portion 118 and the tip of the insertion portion (the tip of the insertion tube portion 113) is greater than the insertion length required for temporary attachment. Then, as the insertion portion (the insertion tube portion 113 and the weir portion 117) is inserted into the foam insulation layer 15, when the tip (the rib tip surface) of the sensing portion 118 abuts against the surface of the foam insulation layer 15, resistance is generated against the insertion of the insertion portion into the foam insulation layer 15. After generating resistance, the sensing portion 118 is configured to be able to move further toward the foam insulation layer 15 and penetrate into the foam insulation layer 15. At this time, because the tip of the sensing part 118 forms an inclined surface, the sensing part 118 gradually penetrates into the foam insulation layer 15, and the resistance increases as the sensing part 118 penetrates further. The user can feel the increase in resistance when screwing in the screw, and can prevent the fixing body 110 from being pushed in too far and crushing the foam insulation layer 15 too much.
[0044] Next, with reference to Figures 4 and 5, a fixing structure in which the fixing body 110 is fixed to the wall 11 will be described. Figure 4 is a schematic perspective view of the fixing structure. Figures 5(a) and 5(b) are a BB cross-sectional view and a B'-B' cross-sectional view of the fixing structure. Here, the wall 11 is made of a hard base wall 13 and a foam insulation layer 15 formed on the surface of the base wall 13. This base wall 13 may be a concrete wall. The foam insulation layer 15 may also be a spray-applied foam insulation material such as urethane foam formed on the surface of the base wall 13.
[0045] As shown in Figures 4 and 5, the fixed body 110 is fixed to the surface of the foam insulation layer 15 of the wall 11. The abutment portion 112 of the fixed body 110 abuts against the surface of the foam insulation layer 15, and the insertion tube portion 113 and the weir portion 117, which serve as the insertion portion of the fixed body 110, are inserted into the foam insulation layer 15. At this time, the tip of the insertion tube portion 113 (insertion portion) is spaced apart from the surface of the base wall 13. In other words, the protrusion amount of the insertion tube portion 113 is smaller than the thickness of the foam insulation layer 15. Furthermore, the sensing portion 118 penetrates into the foam insulation layer 15. A screw penetrates the insertion path 116 of the insertion tube portion 113 and is driven in until the tip of the screw reaches the base wall 13. Here, the tip of the screw is screwed into the base wall 13, firmly fixing the fixed body 110 to the wall 11. In particular, since the insertion tube portion 113 is spaced apart from the surface of the base wall 13, the screw is not overtightened with an excessive tightening torque, preventing the screw hole from being damaged (so-called stripping of the screw). Furthermore, the placement area 111a of the main body 111 of the fixing body 110 faces the surface of the wall.
[0046] 5(a), in this fixing structure, the abutting portion 112 extending on the same plane preferentially abuts against the surface of the foamed insulation layer 15, and a recessed portion recessed further than the abutting portion 112 and having an area of more than half the back surface of the main body portion 111 is spaced apart from the surface of the foamed insulation layer 15. In other words, even if the abutting portion 112 bites into the surface of the foamed insulation layer 15, the deformed foamed insulation layer 15 escapes into the recessed portion on the back surface of the main body portion 111, thereby reducing the amount of crushing of the foamed insulation layer. Furthermore, because the fixing body 110 is fixed to the surface of the foamed insulation layer 15 in a manner that avoids excessive screwing, excessive crushing of the foamed insulation layer 15 in the thickness direction is suppressed.
[0047] Next, a method for fixing the fixing body 110 to the surface of the foamed heat insulating layer 15 of the wall 11 will be described with reference to FIGS.
[0048] First, a fixing position corresponding to the center point of the fixed body 110 is determined, and the fixing position is marked on the surface of the wall 11. Based on the marked position, a drill is used to form a pilot hole 12 in the wall 11 for inserting the screw and the insertion tube portion 113. Depending on the length of the screw, the pilot hole 12 preferably penetrates the foam insulation layer 15 and reaches the base wall 13. The diameter of this pilot hole 12 is smaller than the maximum diameter of the screw shank. Specifically, the diameter of the pilot hole 12 is preferably 70 to 90% of the diameter of the screw shank.
[0049] Next, as shown in FIG. 6, the fixed body 110 is held, and the back surface of the main body 111 is brought into contact with the surface of the foamed insulation layer 15 in a substantially parallel relationship. The fixed body 110 is pressed against the surface of the foamed insulation layer 15 so that the insertion tube portion 113 of the fixed body 110 is inserted into the pilot hole 12. As shown in FIG. 7(a), the insertion tube portion 113 is press-fitted into the pilot hole 12, and the pilot hole 12 is forced open to expand its diameter, thereby deforming the foamed insulation layer 15 in the direction away from the insertion tube portion 113. At this time, the press-fit guide portion 115 gradually forces open the pilot hole 12, allowing the insertion tube portion 113 to be inserted smoothly.
[0050] Similarly, the dam portion 117 is inserted into the foam insulation layer 15 by piercing it. When the fixing body 110 is pressed further against the surface of the foam insulation layer 15, the insertion portion (insertion tube portion 113 and dam portion 117) moves further in, and the sensing portion 118 abuts against the surface of the foam insulation layer 15, as shown in FIG. 7(b). The user can sense that resistance to the movement of the insertion portion of the fixing body 110 has occurred or that this resistance has increased as a result of the sensing portion 118 abutting against the surface of the foam insulation layer 15. At this point, the user can sense by touch that the insertion portion has been inserted into the foam insulation layer 15 by more than the insertion length required for temporary attachment, and that a temporary attachment state has been formed in which the fixing body 110 is at least prevented from falling out of the foam insulation layer 15 due to its own weight. The user then stops pushing the fixing body 110.
[0051] 7(b) and 8 show the relationship between the insertion portion of the fixed body 110 and the foamed insulation layer 15 in a temporarily attached state. In this temporarily attached state, the temporary attachment force is generated mainly by the force of the elastically expanded pilot hole 12 returning to its original shape, causing the foamed insulation layer 15 to press against the outer circumferential surface of the tubular shaft portion 114. Furthermore, as shown in FIGS. 7(b) and 8, in this temporarily attached state, the receiving surface 117a of the weir portion 117 receives a portion of the foamed insulation layer 15 that has expanded and deformed around the tubular shaft portion 114 of the insertion tubular portion 113, compressing the foamed insulation layer 15 between the tubular shaft portion 114 and the receiving surface 117a, making it relatively dense. The locally dense foamed insulation layer 15 improves the pressure contact force between the foamed insulation layer 15 and the tubular shaft portion 114, effectively preventing gaps from forming around the tubular shaft portion 114 and reducing the temporary attachment force.
[0052] In this way, by inserting the insertion tube portion 113 into the pilot hole 12, it is possible to accurately determine the temporary attachment position relative to the pilot hole 12. Furthermore, when the foamed insulation layer 15 is a sprayed foam insulation material, the foamed insulation layer 15 actually has an uneven surface, but by temporarily attaching it at one point, the insertion tube portion 113 and the pilot hole 12, it is possible to prevent tilting and misalignment due to the uneven surface.
[0053] With the fixing body 110 temporarily attached to the surface of the foam insulation layer 15, the user can release the fixing body 110 and prepare screws and tools. Then, the user inserts the screw into the insertion path 116 of the insertion tube portion 113 of the fixing body 110 from the surface side of the wall. At this time, the screw is held in the screw temporary holding portion 119 of the main body portion 111, so the screw will not fall even if the user releases the screw. As shown in Figure 9, when the user operates a tool (such as a screwdriver or power tool) to screw the screw, the screw penetrates the foam insulation layer 15 and is screwed into the pilot hole 12 of the base wall 13. At this time, multiple weir portions 117 prevent the fixing body 110 from rotating together with the screw.
[0054] When the head of the screw abuts against the surface of the main body 111 of the fixed body 110, the engagement between the sensor 118 and the foam insulation layer 15 creates new resistance to the screw's screwing (or the movement of the inserted portion). Sensing this resistance allows the user to carefully perform the subsequent screwing operation. That is, the user can operate the tool at a slower speed than before the resistance caused by the sensor 118 occurred, and continue to screw the screw until the abutment portion 112 abuts against the surface of the foam insulation layer 15, thereby moving the inserted portion further into the wall 11. At this time, the screw begins to thread, causing the fixed body 110 to move in the screwing direction. By visually checking this movement, the user can stop the screwing operation or carefully perform the subsequent screwing operation. In particular, the sensor 118 can detect when the abutment portion 112 is separated from the surface and stop the screwing operation before the abutment portion 112 sinks in too far. The sensor 118 can be positioned to ensure sufficient travel distance.
[0055] When the abutment portion 112 abuts against the surface of the foam insulation layer 15, further resistance is generated in the screw rotation (or movement of the inserted portion). The user stops the screw rotation operation as soon as they sense the generation of this second resistance. This prevents the abutment portion 112 from over-compressing the foam insulation layer 15 while fixing the fixing body 110 to the surface of the foam insulation layer 15. As a result, a fixed structure can be constructed in which the fixing body 110 is fixed to the installation surface of the wall 11, as shown in FIG. 4.
[0056] The above explanation is merely one example of a method for fixing the fixing body 110, and each step may be changed. For example, the fixing body 110 may be pressed against the surface of the foamed insulation layer 15 in a state where the screw is first held in the screw temporary holding portion 119, thereby forming a temporary attachment state.
[0057] In a conventional box abutment (fixed body) such as that described in Patent Document 1, if screws are used instead of fixing nails, and the box abutment abuts the concrete wall and the box bottom wall as a result of the screw being turned, and the user continues to turn the screw without noticing, or realizing too late, the screw, whose forward threading is restricted, may spin freely in the same position relative to the concrete, losing its grip on the concrete and weakening its fixing force, which could lead to it coming out. In contrast, in this embodiment, the sensor 118 abuts against the foam insulation layer 15 before the abutment portion 112 abuts against the foam insulation layer 15, thereby notifying the user of the progress of the insertion portion of the fixed body 110 and allowing the user to stop the press-fit operation before the tip of the insertion tube portion 113 abuts against the base wall 13. In particular, the sensor 118 temporarily stops the fixing body 110 when the abutting portion 112 is separated from the installation surface. This allows the insertion portion of the fixing body 110 to be advanced little by little, preventing excessive crushing of the foam insulation layer 15. In other words, the sensor 118 not only indicates the temporary attachment position to the user, but also allows for an extra stroke of movement. The user can then carefully rotate the screw to properly secure the fixing body 110 to the wall 11. In other words, an extra stroke is ensured to stop the screw from rotating between the start of further pushing in of the insertion portion of the fixing body 110 and the abutting portion 112 abutting the surface of the foam insulation layer 15. This makes it easy for the user to determine when to stop the screw's rotation, preventing excessive crushing of the foam insulation layer 15 or the screw from spinning freely.
[0058] The following describes the effects of the fixed body 110 according to one embodiment of the present invention.
[0059] The fixed body 110 according to one embodiment of the present invention is provided with an insertion tube portion 113 that protrudes in the axial direction from the back side of the main body portion 111. The tip of the insertion tube portion 113 is provided with a press-fit guide portion 115 that has a tapered surface that is inclined with respect to the axial direction so as to form a tapered shape at the tip end beyond the axial portion 114, and that guides the insertion of the insertion tube portion 113 into the foamed insulation layer 15. That is, when the back side of the fixed body 110 is pressed toward the foamed insulation layer 15, the press-fit guide portion 115 guides the insertion of the insertion tube portion 113 into the foamed insulation layer 15, thereby making it easy to position the fixed body 110 at a fixed position on the surface of the foamed insulation layer 15. The fixed body 110 is also provided with a temporary attachment portion (such as the axial portion 114) that, when the insertion tube portion 113 is press-fitted into the foamed insulation layer 15, creates a temporarily attached state that prevents the fixed body 110 from falling out of the foamed insulation layer 15 due to its own weight. This allows the user to easily fix the fixture 110 to the wall 11 by operating a screw and a tool to insert and drive a screw into the insertion path 116 formed in the insertion tube portion 113 from the surface side of the wall, without having to hold the fixture 110 by hand. Therefore, the fixture 110 of this embodiment improves the workability of the fixing work to the surface of the foam insulation layer 15 of the wall 11.
[0060] [Wiring / piping material holder device] As one example of use of the fixed body 110 of this embodiment, a wiring and piping material holder device 100 for disposing wiring and piping material 17 on a wall 11 to be disposed will be described. The wiring and piping material holder device 100 of one embodiment of the present invention is a device comprising the fixed body 110 and a wiring and piping material holder 130 used to hold the wiring and piping material 17 and dispose the wiring and piping material 17 on a structure. In other words, the wiring and piping material holder device 100 is a device for disposing the wiring and piping material 17 on the disposing surface by holding the wiring and piping material 17 while being fixed to the disposing surface of the wall 11 that constitutes the structure. However, it goes without saying that this embodiment is merely one example of the present invention, and its use and configuration are not limited as long as they do not deviate from the technical scope of the present invention.
[0061] Fig. 10 is an exploded perspective view of the wiring / piping material holder device 100. As shown in Fig. 10, the wiring / piping material holder device 100 is composed of a fixed body 110 and a wiring / piping material holder 130, which can be assembled together.
[0062] The wiring and piping material holder 130 is separate from the fixed body 110 and is configured to be used in conjunction with the fixed body 110 to hold the wiring and piping material 17 and arrange the wiring and piping material 17 on an arrangement surface. Hereinafter, with reference to FIGS. 11 to 14, a wiring and piping material holder 130 according to one embodiment of the present invention will be described. FIGS. 11(a) and 11(b) are perspective views of the wiring and piping material holder 130 according to one embodiment of the present invention. FIG. 12 is a front view of the wiring and piping material holder 130. FIGS. 13(a) to 13(d) are plan, left side, right side, and bottom views of the wiring and piping material holder 130. FIGS. 14(a) and 14(b) are DD and D'-D' cross-sectional views of the wiring and piping material holder 130.
[0063] The wiring / piping material holder 130 is fixed to a structure and is configured to hold or grip the wiring / piping material 17 in a holding space serving as a holding portion, thereby arranging the wiring / piping material 17 in a predetermined arrangement direction along the wall surface of the structure. That is, the wiring / piping material holder 130 includes a holding portion 135 that holds the wiring / piping material 17 and a fixing hole 136 that serves as a fixing portion through which a screw is inserted to fix the wiring / piping material to the wall. As shown in FIG. 12 , the wiring / piping material holder 130 is substantially C-shaped in a front view to define an open holding space. In this embodiment, the wiring / piping material holder 130 is integrally molded from synthetic resin, and the belt-shaped portion has flexibility and elasticity.
[0064] The wiring / piping material holder 130 of this embodiment includes a base 131 extending from the base end to the tip, a holding piece 132 extending from the base end to the tip and cooperating with the base 131 to surround the wiring / piping material 17 and hold it along the installation direction, a hinge 133 rotatably connecting the base end side of the base 131 and the base end side of the holding piece 132 to each other, and an auxiliary piece 134 standing up from the inner surface of the base 131 with its tip as a free end. In the wiring / piping material holder 130 of this embodiment, the base 131, holding piece 132, hinge 133 and auxiliary piece 134 are integrally formed.
[0065] As shown in FIGS. 11 to 14 , in the initial state of the wiring / piping material holder 130 (not holding the wiring / piping material 17), an opening is formed between the tip of the base 131 and the tip of the holding piece 132 for introducing the wiring / piping material 17 therein. A holding section 135 is defined inside the base 131 and the holding piece 132, communicating with the opening, as a holding space for holding the wiring / piping material 17. When the base 131 and the holding piece 132 rotate or displace relatively about the hinge 133, the tip of the base 131 overlaps with the tip of the holding piece 132, thereby forming an annular holding section 135 that circumferentially surrounds the wiring / piping material 17. At this time, the holding piece 132 overlaps with the base 131 from the outside (radially outside) of the holding space. 14(a), this closed holding space can be maintained by engagement between the first locking portion (first locking tooth row 131a) of the base 131 and the second locking portion (second locking tooth row 132a) of the holding piece 120. The first locking portion and the second locking portion are released from engagement by moving away from each other in a direction different from the locking direction (i.e., in the radial direction).
[0066] A flat fixing surface is defined on the bottom surface of the base 131. As shown in FIG. 14(b), a recess for accommodating the head of a fixing screw is provided approximately in the center of the extension direction of the base 131. A fixing hole (fixing portion) 136 is formed at the bottom of the recess, penetrating the base 131 from top to bottom and into which the shank of the screw is inserted when fixing to a structure. The fixing surface of the base 131 is disposed so as to abut against the arrangement region 111a of the main body 111. Here, the area facing the surface of the foam insulation layer 15 on the back side of the fixed body 110 is larger than the abutting area of the wiring / piping material holder 130 abutting against the arrangement region 111a.
[0067] FIG. 15 shows a first use example of the wiring and piping material holder device 100 in which the wiring and piping material holder 130 is combined with the fixed body 110. The fixed body 110 and the wiring and piping material holder 130 are combined so that the fixing hole 136 of the base 131 communicates with the opening of the insertion path 116 of the fixed body 110. The wiring and piping material holder 130 can be positioned relative to the fixed body 110 by aligning the contour of the fixing surface of the base 131 with the line of the arrangement area 111a on the surface of the main body 111. FIG. 16 shows a second use example of the wiring and piping material holder device 100 in which the wiring and piping material holder 130 is combined with the fixed body 110. The wiring and piping material holder device 100 in FIG. 16 is obtained by rotating the base 131 90 degrees on the arrangement area 111a in comparison with the use example in FIG. 15, and combining the wiring and piping material holder 130 with the fixed body 110. That is, the arrangement area 111a allows the wiring / piping material holder 130 to be aligned and arranged in two different arrangement directions.
[0068] Next, an installation structure in which a wiring / piping material holder 130 is installed on the installation surface of a wall 11 will be described with reference to Figures 17 to 19. Figure 17 is a schematic perspective view of the installation structure. Figure 18 is a cross-sectional view of the installation structure. Figure 19 is a cross-sectional view of a wiring / piping material installation structure in which wiring / piping material 17 is installed. Here, the wall 11 is made up of a hard base wall 13 and a foam insulation layer 15 formed on the surface of the base wall 13, similar to the fixed structure described above.
[0069] As shown in Figures 17 and 18, the wiring / piping material holder 130 is fixed to the surface of the foam insulation layer 15 of the wall 11. The fixing surface of the wiring / piping material holder 130 is placed on the surface of the main body 111 of the fixing body 110, and the abutment portion 112 of the fixing body 110 abuts against the surface of the foam insulation layer 15. The insertion tube portion 113 and the weir portion 117 as the insertion portion of the fixing body 110 are inserted into the foam insulation layer 15. At this time, the tip of the insertion tube portion 113 (insertion portion) is spaced apart from the surface of the base wall 13. Furthermore, the sensing portion 118 penetrates into the foam insulation layer 15. A screw is driven through the fixing hole 136 and the insertion path 116 until it reaches the base wall 13. Here, the tip of the screw is screwed into the base wall 13, firmly fixing the fixing body 110 to the wall 11. The holding portion 135 of the wiring / piping material holder 130 is exposed on the surface of the wall.
[0070] 5(a), in this installation structure, the abutting portion 112 extending on the same plane preferentially abuts against the surface of the foamed insulation layer 15, and a recessed portion recessed further than the abutting portion 112 and having an area of more than half the back surface of the main body portion 111 is spaced apart from the surface of the foamed insulation layer 15. In other words, even if the abutting portion 112 bites into the surface of the foamed insulation layer 15, the deformed foamed insulation layer 15 escapes into the recessed portion on the back surface of the main body portion 111, thereby reducing the amount of crushing of the foamed insulation layer. Furthermore, because the fixing body 110 is fixed to the surface of the foamed insulation layer 15 in a manner that avoids excessive screwing, excessive crushing of the foamed insulation layer 15 in the thickness direction is suppressed.
[0071] FIG. 19 shows a wiring / piping arrangement structure in which the wiring / piping material 17 is held by the holding portion 135 in the installation structure of FIG. 18 . In this wiring / piping arrangement structure, the wiring / piping material 17 is held in the closed holding portion 135 of the wiring / piping material holder 130. The tip portions of the base 131 and the holding piece 132 overlap, and the second locking tooth row 132a engages with the first locking tooth row 131a from the radially outer side, thereby maintaining the closed state of the holding portion 135. The locking surfaces of the first locking tooth row 131a and the second locking tooth row 131b are locked in the circumferential direction, restricting relative movement of the holding piece 132 with respect to the base 131 in a direction in which the overlap retreats. In addition, the auxiliary piece 134 is located between the outer peripheral surface of the wiring / piping material 17 and the hinge 133. The auxiliary piece 134 prevents the wiring / piping material 17 from escaping from the holding portion 135 into the space on the hinge side, thereby maintaining a firm grip on the wiring / piping material 17 by the wiring / piping material holder 130.
[0072] Next, a method for installing the wiring / piping material holder device 100 on the installation surface of the wall 11 (surface of the foamed heat insulating layer 15) will be described with reference to FIGS.
[0073] First, pilot holes 12 for inserting the screws and insertion tube portions 113 into the wall 11 are formed in the base wall 13 and the foam insulation layer 15. Next, the fixing surface of the base 131 of the wiring / piping material holder 130 is abutted against the placement area 111a of the fixed body 110, and the fixing surface is aligned so that the insertion path 116 and the fixing hole 136 communicate with each other. As shown in FIG. 20 , the screw is passed through the insertion path 116 into the fixing hole 136. At this time, the screw shaft is temporarily held by the screw temporary holding portion 119, so the wiring / piping material holder 130 is suspended by the screw. In other words, because the wiring / piping material holder 130 is supported or temporarily held integrally with the fixed body 110 via the screw, the wiring / piping material holder 130 and the screw will not fall from the fixed body 110 even if the user releases their hands from them.
[0074] As shown in FIG. 20 , the integrated wiring and piping material holder device 100 is held, and the back surface of the main body 111 is positioned substantially parallel to the surface of the foamed insulation layer 15. The wiring and piping material holder device 100 is pressed against the surface of the foamed insulation layer 15 so that the insertion tube portion 113 of the fixing body 110 is inserted into the prepared hole 12. As shown in FIG. 21( a ), the insertion tube portion 113 pushes and expands the diameter of the prepared hole 12, causing the foamed insulation layer 15 to deform in the direction away from the insertion tube portion 113. At this time, the press-fit guide portion 115 gradually pushes and expands the prepared hole 12, allowing the insertion tube portion 113 to be inserted smoothly. Similarly, the weir portion 117 is inserted into the foamed insulation layer 15 by piercing it. When the wiring / piping material holder device 100 is further pressed against the surface of the foam insulation layer 15, the insertion portion (insertion tube portion 113 and weir portion 117) moves further inward, and the sensing portion 118 abuts against the surface of the foam insulation layer 15, as shown in FIG. 21(b). The user can sense that resistance or an increase in resistance has occurred to the movement of the insertion portion of the fixed body 110 due to the sensing portion 118 abutting against the surface of the foam insulation layer 15. At this point, the user can sense by touch that the insertion portion has been inserted into the foam insulation layer 15 to a depth greater than the insertion length required for temporary attachment, and that a temporary attachment state has been formed in which the wiring / piping material holder device 100 will not fall from the foam insulation layer 15 due to its own weight. The user then stops pushing the wiring / piping material holder device 100.
[0075] That is, the temporary attachment portion can maintain the temporary attachment state when the fixed body 110 and the wiring / piping material holder 130 are assembled, and can also temporarily attach the wiring / piping material holder 130 while it is suspended on the screw temporarily held by the temporary screw holding portion. In this temporary attachment state, a temporary attachment force is generated mainly by the force of the elastically expanded pilot hole 12 attempting to return to its original shape, causing the foamed insulation layer 15 to press against the outer peripheral surface of the tubular shaft portion 114. Also, in this temporary attachment state, similar to the embodiment shown in FIG. 8 , the receiving surface 117a of the weir portion 117 receives a portion of the foamed insulation layer 15 that has expanded and deformed around the tubular shaft portion 114 of the insertion tubular portion 113, thereby compressing the foamed insulation layer 15 between the tubular shaft portion 114 and the receiving surface 117a to become relatively dense. In this way, by making the foamed insulation layer 15 locally dense, the pressure contact force between the foamed insulation layer 15 and the tubular shaft portion 114 is improved, and gaps around the tubular shaft portion 114 and a decrease in temporary attachment strength can be effectively prevented.
[0076] With the wiring and piping material holder 100, which temporarily holds the screws, temporarily attached to the surface of the foam insulation layer 15, the user can release the wiring and piping material holder 100 and prepare tools. At this time, the wiring and piping material holder 100 and the screws are temporarily attached to the wall 11, so the wiring and piping material holder 100 will not fall even if the user releases their hands. As shown in FIG. 22 , when the user operates a tool (such as a screwdriver or power tool) to screw the screw, the screw penetrates the foam insulation layer 15 and is screwed into the pilot hole 12 in the base wall 13. At this time, multiple weir portions 117 prevent the wiring and piping material holder 100 from rotating together with the screw.
[0077] When the head of the screw abuts against the base 131, the engagement between the sensor 118 and the foam insulation layer 15 creates new resistance to the screw's screwing (or the movement of the inserted portion). Sensing this resistance allows the user to carefully perform the subsequent screwing operation. That is, the user operates the tool at a slower speed than before the resistance from the sensor 118 occurred, and continues to screw the screw until the abutment portion 112 abuts against the surface of the foam insulation layer 15, moving the inserted portion further into the wall 11. When the abutment portion 112 abuts against the surface of the foam insulation layer 15, further resistance is generated to the screw's screwing (or the movement of the inserted portion). The user stops screwing the screw upon sensing the second resistance. This prevents the abutment portion 112 from over-compacting the foam insulation layer 15 while securing the wiring and piping material holder device 100 to the surface of the foam insulation layer 15. As a result, an installation structure can be constructed in which the wiring / piping material holder device 100 is installed on the installation surface of the wall 11 as shown in FIG.
[0078] Then, by operating the wiring / piping material holder 130 fixed to the wall 11 via the fixed body 110 and holding the wiring / piping material 17 in the holding portion 135, it is possible to construct a wiring / piping material arrangement structure such as that shown in Figure 19.
[0079] [Variations] The present invention is not limited to the above-described embodiment, and various modifications are possible. Modifications of the present invention will be described below. In each modification, components designated by three digits that share the same last two digits have the same or similar characteristics unless otherwise specified, and their description will be omitted.
[0080] (1) The fixed body of the present invention is not limited to the configuration of the above-described embodiment. Figure 23 is a schematic cross-sectional view of a fixed body 210 according to another embodiment of the present invention. The fixed body 210 includes a main body portion 211, an insertion tube portion 213 that protrudes in the axial direction from the back surface of the main body portion 211, a dam portion 217 that protrudes from the back surface of the main body portion 211 and surrounds the periphery of the insertion tube portion 213, and a sensing portion 218 that protrudes further toward the back surface than the abutting portion 212 of the main body portion 211 and protrudes less than the insertion tube portion 213 and the dam portion 217. The insertion tube portion 213 includes a tube shaft portion 214, a press-fit guide portion 215, and an insertion path 216. In this embodiment, the tube shaft portion 214 is adjacent to the press-fit guide portion 215 and expands in diameter toward the base end at a gentler angle than the tapered surface of the press-fit guide portion 215. Furthermore, the insertion path 216 extends so as to gradually reduce in diameter toward the tip. Furthermore, in this embodiment, a temporary screw holding portion 219 for temporarily holding a screw is formed as a protrusion located midway along the insertion path 216. Furthermore, the dam portion 217 is formed in an annular shape extending around the insertion tube portion 213. In other words, the fixing body of the present invention can have various shapes as long as it conforms to the technical concept of the present invention.
[0081] (2) The fixing body of the present invention is not limited to the configuration of the above embodiment. For example, the fixing body may be configured so as to lack some or all of the dam portion, the sensing portion, and the temporary screw holding portion. Even in this case, by inserting at least the insertion tube portion into the foam insulation layer by a predetermined length, the tube shaft portion pressed into the foam insulation layer can form a temporary attachment state as a temporary attachment portion.
[0082] (3) The wiring and piping material holder device of the present invention is not limited to the configuration of the above embodiment. That is, in the wiring and piping material holder device, the wiring and piping material holder may take any different form as long as it is capable of at least holding the wiring and piping material. For example, in the above embodiment, the wiring and piping material holder has a base, holding pieces, and hinges formed integrally, but it may also be a combination of separate parts.
[0083] (4) The wiring and piping material holder device of the present invention is not limited to the configuration of the above embodiment. Fig. 24 shows a wiring and piping material holder device 300 of another embodiment. The wiring and piping material holder device 300 is configured to be temporarily held by a wall 31 that does not have a foam insulation layer. That is, the wiring and piping material holder device 300 comprises a fixed body 310 that is fixed to the wall 31 to hold the wiring and piping material arranged along the installation surface of the wall 31, and a wiring and piping material holder 330 that is separate from the fixed body 310 and is fixed to the wall 31 together with the fixed body 310 to hold the wiring and piping material. The fixed body 310 includes an arrangement area 311a formed on the front side of the fixed body 310 and in which the wiring / piping material holder 330 is arranged, an insertion path 316 that penetrates the fixed body 310 from front to back and into which a screw to be driven into the installation surface is inserted, a temporary screw holding portion 319 formed within or adjacent to the insertion path 316 and that temporarily holds the screw inserted into the insertion path 316, and a temporary attachment portion 320 that allows the fixed body 310 to be temporarily attached to the installation surface while the back side of the fixed body 310 is abutted against the installation surface to prevent it from falling off the installation surface due to its own weight. Here, the temporary attachment portion 320 is made of an adhesive layer that can be adhered to the wall 31 or a magnet that can be magnetically attached to the metal wall 31. The wiring / piping material holder 330 also includes a holding portion 335 that holds the wiring / piping material and a fixing portion 336 that is fixed to the installation surface together with the fixed body 310 by an inserted screw. The temporary attachment portion 320 can be temporarily attached in a state where the wiring / piping material holder 330 is suspended and held by the screw temporarily held by the screw temporary holding portion 319 .
[0084] (5) In the above embodiment, the wall is described as a ceiling wall, but the present invention is not limited to this and may be a wall surface of a vertically erected wall or a sloping wall. The fixing body of the present invention can maintain a temporary attachment state even when fixed to a vertical or sloping installation surface, thereby improving workability.
[0085] The present invention is not limited to the above-described embodiments and modifications, and can be implemented in various forms within the technical scope of the present invention. That is, within the technical scope of the present invention, some of the configurations of the present embodiments may be omitted or modified, or other configurations may be added.
