Description

Technical Field

[0001] The present invention relates to an attachment structure for a lip channel-shaped steel material, an attachment body, and an installation structure of the attachment body, which can be attached to various lip channel-shaped steel materials.

Background Art

[0002] Conventionally, there has been an attachment body attached to a lip channel-shaped steel. For example, as shown in FIG. 11, the attachment body 13 described in Patent Document 1 includes a pair of locking plate portions 14, 14 respectively locked to the back surfaces of a pair of opposing plate portions 11a, 11a, 12a, 12a (lip portions) of the first base body 11 and the second base body 12 (lip channel-shaped steel), a clamping plate portion 15 disposed so as to cross the groove portions 11b, 12b between the opposing plate portions on the front surface side of the pair of opposing plate portions 11a, 11a, 12a, 12a, and a shaft portion 16 connecting the locking plate portions 14, 14 and the clamping plate portion 15 through the groove portions 11b, 12b. The attachment body 13 is attached to the base bodies 11, 12 by clamping the opposing plate portions 11a, 11a, 12a, 12a with the pair of locking plate portions 14 and the clamping plate portion 15. The clamping plate portion 15 of the attachment body 13 has a first clamping plate portion 15a, 15a on the central side and a second clamping plate portion 15b, 15b on both end sides in the opposing direction of the pair of opposing plate portions 11a, 11a, 12a, 12a. By forming the back sides of the first clamping plate portion 15a and the second clamping plate portion 15b in a stepped shape, the attachment body 13 can correspond to two types of base bodies 11, 12 having different shapes of the opposing plate portions 11a, 12a as long as the widths of the groove portions 11b, 12b of the base bodies 11, 12 are the same.

[0003] In addition, the wiring and pipe support 22 described in Patent Document 2 shown in FIG. 12 is also an attachment body attached to the lip channel steel 21, and includes a support portion 23 for supporting the wiring and pipe materials, and an arcuate extension plate portion 24 extending from the support portion 23. The support portion 23 is composed of a support main body portion 23a and a tightening portion 23b. Further, a connecting protrusion 24a is provided at one end of the extension plate portion 24, and a gap between the other end of the extension plate portion 24 and the support main body portion 23a serves as a lip hooking portion 25. Therefore, to attach this wiring and pipe support 22 to the lip channel steel 21, the connecting protrusion 24a is positioned at the corner portion 21a at the bottom of the lip channel steel 21, and then the extension plate portion 24 is elastically deformed so as to be bent, and the lip hooking portion 25 is hooked on the lip portion 21b of the lip channel steel 21. At this time, the extension plate portion 24 is in a tensioned state between the bottom wall 21c and the lip portion 21b of the lip channel steel 21 due to its elastic restoring force, and thereby, the extension plate portion 24, and thus the wiring and pipe support 22, is attached to the lip channel steel 21.

Summary of the Invention

Problems to be Solved by the Invention

[0005] By the way, in the attachment member 13 described in the conventional Patent Document 1, although it could be shared by the base bodies 11 and 12 (lip groove steel) with different shapes of the opposing plate portions 11a and 12a (lip portions), it could not be shared by the base bodies (lip groove steel) with different widths of the groove portions 11b and 12b (the interval between a pair of opposing lip portions). Further, in the wiring and pipe support member 22 described in Patent Document 2, when attaching to the lip groove steel 21, it was not affected by the interval between a pair of opposing lip portions 21b and 21b, but the interval between the bottom wall 21c of the lip groove steel 21 and the lip portion 21b corresponded only to the lip groove steel 21 within the range where the extending plate portion 24 could elastically contact (the range where the extending plate portion 24 was in a stretched state).

[0006] This invention has been made to solve the above-described conventional problems, and its object is to provide an attachment portion structure to a lip groove steel material, an attachment body, and an installation structure of the attachment body that can be attached without being restricted by the interval between a pair of lip portions of the lip groove steel material and the interval between the bottom wall and the lip portion.

Means for Solving the Problems

[0007] The attachment portion structure to a lip groove steel material, the attachment body, and the installation structure of the attachment body according to this invention are configured as follows in order to achieve the above object. That is, The attachment structure to the lip channel-shaped steel according to the invention described in claim 1 is the attachment structure of the attachment body attached to the lip channel-shaped steel to the lip channel-shaped steel. Here, the lip channel-shaped steel includes a bottom wall, a pair of side walls standing from both ends of the bottom wall and facing each other, a flange portion extending inward from both tips of the pair of side walls, and a pair of lip portions extending so as to be folded back from the side walls with a bent portion bent from the tip of the flange portion toward the bottom wall. Therefore, the attachment structure includes an arrangement space forming portion that forms an arrangement space in which one of the pair of lip portions is arranged, and an opening through which the lip portion can pass in order to insert the one lip portion into the arrangement space. The arrangement space forming portion includes a base wall that abuts against the outer surface of the tip portion of the side wall on which the one lip portion is provided and sandwiches the tip portion of the side wall and the one lip portion in a state where the one lip portion is arranged in the arrangement space, and an opposing wall that abuts against the outer surface of the bent portion of the one lip portion. Further, the arrangement space forming portion includes a first movement restricting portion that restricts movement of the attachment body in a direction approaching the bottom wall of the attachment body from the side far from the bottom wall and opposing the one lip portion. And the arrangement space forming portion includes a second movement restricting portion that restricts movement of the attachment body in a direction away from the bottom wall of the attachment body from the side close to the bottom wall and opposing the one lip portion.

[0008] According to this attachment structure, the attachment structure includes an arrangement space forming portion that forms an arrangement space in which one of the lip portions in the lip channel-shaped steel is arranged, and an opening. Through the opening, the one lip portion is inserted into the arrangement space. And the arrangement space forming portion includes a base wall and an opposing wall. By the base wall and the opposing wall, the attachment body is prevented from moving in a direction facing each other between the pair of lip portions of the lip channel-shaped steel. Further, the arrangement space forming portion includes a first movement restricting portion and a second movement restricting portion. By the first movement restricting portion and the second movement restricting portion, the attachment body is restricted from moving in a direction orthogonal to the bottom wall of the lip channel-shaped steel. Thus, the movement of the attachment body is restricted, and the attachment body is attached to one of the lip portions of the lip channel-shaped steel.

[0009] Further, the attachment portion structure to the lip groove-shaped steel material according to the invention described in claim 2 is the attachment portion structure to the lip groove-shaped steel material described in claim 1, and as the opposing wall, it includes an elastic piece having an elastic restoring force. Therefore, when this elastic piece is pushed by the one lip portion entering the arrangement space from the opening portion and elastically deformed, the one lip portion is arranged in the arrangement space, and the elastic piece abuts against the bent portion of the one lip portion arranged in the arrangement space.

[0010] Further, the attachment portion structure to the lip groove-shaped steel material according to the invention described in claim 3 is the attachment portion structure to the lip groove-shaped steel material described in claim 2. In order to correspond to a plurality of types of lip groove-shaped steel materials in which the distance between one of the side walls and the bent portion and / or the tip position of the bent portion with respect to the flange portion are different, the elastic piece has a plurality of opposing surfaces that abut against the outer surface of the bent portion and a second movement restricting portion that is formed to protrude continuously with the opposing surface.

[0011] Further, the attachment portion structure for the lip groove-shaped steel material according to the invention described in claim 4 is the attachment portion structure of the attachment body attached to the lip groove-shaped steel material. Here, the lip groove-shaped steel material includes a bottom wall, a pair of side walls that stand up from both ends of the bottom wall and face each other, a flange portion that extends inward from both tips of the pair of side walls, and a pair of lip portions that are folded back from the side walls by a bent portion that is bent from the tip of the flange portion toward the bottom wall. Therefore, the attachment portion structure includes an arrangement space forming portion that forms an arrangement space in which one of the pair of lip portions is arranged, and an opening through which the one lip portion can pass for insertion into the arrangement space. The arrangement space forming portion includes an abutting portion on one side that abuts on the outer surface of the connecting portion between one of the side walls and the flange portion, the outer surface of the portion extending from the tip portion of one of the side walls to the flange portion, or the outer surfaces of the tip portion of one of the side walls and the flange portion. Further, the arrangement space forming portion includes an elastic piece having an elastic restoring force. Therefore, when the elastic piece is pushed by the one lip portion entering the arrangement space from the opening and elastically deformed, the one lip portion is arranged in the arrangement space, and the elastic piece abuts on the tip portion of the bent portion of the one lip portion arranged in the arrangement space and presses the one lip portion toward the side of the abutting portion on one side.

[0012] According to this attachment portion structure, the attachment portion structure includes an arrangement space forming portion that forms an arrangement space in which one of the lip portions in the lip groove-shaped steel material is arranged, and an opening. Through the opening, one lip portion is inserted into the arrangement space. And the arrangement space forming portion includes an abutting portion on one side and an elastic piece, and the abutting portion on one side and the elastic piece sandwich one lip portion, whereby the attachment body is attached to one lip portion.

[0013] Further, the attachment structure to the lip groove-shaped steel material according to the invention described in claim 5 is the attachment structure to the lip groove-shaped steel material described in claim 1, and in order to correspond to two types of lip groove-shaped steel materials with different intervals between one of the side walls and the bent portion, as the opposed wall, an extended wall extending toward the bottom wall, and an elastic piece having an elastic restoring force that extends from the extended wall with the bottom wall side as the base end and the tip side projects into the arrangement space are provided. Therefore, a first restricting portion as the second movement restricting portion for one of the two types of lip groove-shaped steel materials is provided on the extended wall for one of the two types of lip groove-shaped steel materials. And a second restricting portion as the second movement restricting portion for the other of the two types of lip groove-shaped steel materials is provided on the elastic piece for the other of the two types of lip groove-shaped steel materials.

[0014] Further, the attachment structure to the lip groove-shaped steel material according to the invention described in claim 6 is the attachment structure to the lip groove-shaped steel material described in any one of claims 1 to 3, and the arrangement space forming portion includes a side wall inner surface contact portion that is between the base wall and the bottom wall and contacts the inner surface of one of the side walls. Therefore, the space between the tip of the base wall and the side wall inner surface contact portion becomes the opening.

[0015] Further, the attachment body according to the invention described in claim 7 is an attachment body provided with the attachment structure to the lip groove-shaped steel material described in any one of claims 1 to 4.

[0016] Further, the attachment body according to the invention described in claim 8 is an attachment body provided with the attachment structure to the lip groove-shaped steel material described in claim 6 and a holding portion for holding wiring and piping materials.

[0017] Further, the installation structure of the attachment body according to the invention described in claim 9 is an installation structure of an attachment body in which an attachment body provided with the attachment structure to the lip groove-shaped steel material described in any one of claims 1 to 4 is attached to one lip portion of the lip groove-shaped steel material in a state of being located on the flange portion side away from the bottom wall.

Advantages of the Invention

[0018] According to the attachment structure to the lip channel steel material, the attachment body, and the installation structure of the attachment body according to the present invention, the attachment body can be attached to one of the lip portions regardless of the bottom wall of the lip channel steel material, so that the attachment body can be attached to various lip channel steel materials without being restricted by the distance between the pair of lip portions or the distance between the bottom wall and the lip portion.

Embodiments for Carrying Out the Invention

[0020] Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

[0021] Figs. 1 to 9 show an embodiment of the present invention. In the figures, reference numeral 1 denotes a lip groove-shaped steel material used, for example, as a ceiling base material. 2 denotes an attachment body attached to the lip groove-shaped steel material 1. 3 denotes the attachment structure of the attachment body 2 to the lip groove-shaped steel material 1.

[0022] The lip groove-shaped steel material 1 includes a bottom wall 1a, a pair of side walls 1b, 1b that stand up from both ends of the bottom wall 1a and face each other, and a pair of lip portions 1c, 1c. Here, the pair of lip portions 1c, 1c extend so as to be folded back from the side walls 1b, 1b by flange portions 1d, 1d that extend inward from both tips of the pair of side walls 1b, 1b and bent portions 1e, 1e that are bent from the tips of the flange portions 1d, 1d toward the bottom wall 1a.

[0023] The attachment structure 3 includes an arrangement space forming portion 4 that forms an arrangement space 4a in which one of the pair of lip portions 1c of the lip groove-shaped steel material 1 is arranged, and an opening 5 through which the lip portion 1c can pass in order to insert one of the lip portions 1c into the arrangement space 4a. Here, in a state where one of the lip portions 1c of the lip groove-shaped steel material 1 is arranged in the arrangement space 4a, the arrangement space forming portion 4 includes a base wall 4b that abuts on the outer surface of the tip portion of the one side wall 1b provided with the one lip portion 1c and sandwiches the one lip portion 1c, and an opposing wall 4c that abuts on the outer surface of the bent portion 1e of the one lip portion 1c. Further, the arrangement space forming portion 4 includes a first movement restricting portion 4d that restricts movement of one of the lip portions 1c of the lip groove-shaped steel material 1 in a direction approaching the bottom wall 1a of the attachment body 2, facing from the side far from the bottom wall 1a. And the arrangement space forming portion 4 includes a second movement restricting portion 4e that restricts movement of one of the lip portions 1c of the lip groove-shaped steel material 1 in a direction away from the bottom wall 1a of the attachment body 2, facing from the side close to the bottom wall 1a.

[0024] Specifically, the arrangement space forming portion 4 (mounting portion structure 3) includes, as the opposing wall 4c, an elastic piece 4f having an elastic restoring force. Therefore, as this elastic piece 4f is pushed by one lip portion 1c entering the arrangement space 4a from the opening 5 and elastically deformed, one lip portion 1c is arranged in the arrangement space 4a, and the elastic piece 4f is in a state of elastic deformation and abuts against the bent portion 1e of one lip portion 1c arranged in the arrangement space 4a.

[0025] More specifically, the arrangement space forming portion 4 (mounting portion structure 3) includes, as the opposing wall 4c, an extending wall 4g extending toward the bottom wall 1a, and the elastic piece 4f having an elastic restoring force that extends from the extending wall 4g with the bottom wall 1a side as the base end and the tip side protruding into the arrangement space 4a, in order to correspond to two types of lip groove-shaped steel materials 1, 1 having different intervals between one side wall 1b and the bent portion 1e (the bent portion 1e of one lip portion 1c). Therefore, a first restricting portion 4h as a second movement restricting portion 4e is provided on the extending wall 4g for one of the two types of lip groove-shaped steel materials 1, 1 for that one lip groove-shaped steel material. And a second restricting portion 4i as a second movement restricting portion 4e is provided on the elastic piece 4f for the other of the two types of lip groove-shaped steel materials 1, 1 for that other lip groove-shaped steel material.

[0026] Also, in order to correspond to a plurality of types of lip groove-shaped steel materials 1, 1 having different intervals between one side wall 1b and the bent portion 1e (the bent portion 1e of one lip portion 1c), and / or (in the illustrated embodiment, and) different tip positions of the bent portion 1e with respect to the flange portion 1d, the elastic piece 4f has a plurality of opposing surfaces 4j that abut against the outer surface of the bent portion 1e and the second movement restricting portions 4e (specifically, the second restricting portions 4i) that are formed to protrude so as to be continuous with the opposing surfaces 4j.

[0027] Further, the arrangement space forming portion 4 (mounting portion structure 3) includes a side wall inner surface abutting portion 4k that is between the base wall 4b and the bottom wall 1a of the lip groove-shaped steel material 1 and abuts against the inner surface of one side wall 1b. Therefore, the space between the tip of the base wall 4b and the side wall inner surface abutting portion 4k becomes the opening 5.

[0028] Further, reference numeral 6 in the figure indicates the installation structure of the attachment body 2. In this installation structure 6, the attachment body 2 having the attachment portion structure 3 is attached to one lip portion 1c of the lip groove-shaped steel member 1 in a state of being located on the flange portion 1d side away from the bottom wall 1a.

[0029] Specifically, the attachment body 2 includes the attachment portion structure 3, a holding portion 7 for holding wiring and piping materials (wiring materials or piping materials), a fixing portion 8 to a suspension bolt, and a seat portion 9 for wiring and piping materials for tying and holding the wiring and piping materials. That is, this attachment body 2 is also a wiring and piping material holder for holding wiring and piping materials.

[0030] The holding portion 7 is formed in a substantially U shape by a pair of opposing facing pieces 7a, 7a and a connecting piece 7b connecting these facing pieces 7a, 7a at the lower end. The wiring and piping materials (not shown) are held by being placed in the inner wiring and piping material receiving portion 7c.

[0031] The fixing portion 8 to the suspension bolt includes a bolt seat portion 8a in which one of the pair of facing pieces 7a, 7a (the right facing piece in FIG. 3) extends downward beyond the connecting piece 7b, and sandwiching portions 8b, 8b that project from the bolt seat portion 8a to the opposite side of the wiring and piping material receiving portion 7c and sandwich a suspension bolt (not shown).

[0032] The seat portion 9 for wiring and piping materials is provided on the other facing piece 7a of the pair of facing pieces 7a, 7a on the opposite side of the wiring and piping material receiving portion 7c. This seat portion 9 for wiring and piping materials is supported by leg portions 9a, 9a protruding from the other facing piece 7a. The wiring and piping materials (not shown) are tied to the seat surface (front surface) of the seat portion 9 for wiring and piping materials by a fastening member (not shown) such as a binding wire or a binding band wound around the back side of the seat portion 9 for wiring and piping materials.

[0033] In the attachment structure 3, the base wall 4b that constitutes the aforementioned arrangement space forming portion 4 is composed of a portion of the bolt seat portion 8a that extends downward beyond the connecting piece 7b. The first movement restricting portion 4d is composed of the connecting piece 7b. The extending wall 4g as the opposing wall 4c is formed so as to extend from the first movement restricting portion 4d (connecting piece 7b) to the side opposite to the other opposing piece 7a, and on the surface of the extending wall 4g facing the arrangement space 4a side, there is an opposing surface 4m that abuts against the outer surface of the bent portion 1e of the lip groove-shaped steel material 1. A window 4n is provided in the extending wall 4g so as to communicate the inside and outside of the opening 5. The first restricting portion 4h as the second movement restricting portion 4e is formed so as to protrude from the extending wall 4g toward the arrangement space 4a side on both the left and right sides of the extending wall 4g sandwiching the window 4n.

[0034] Also, an elastic piece 4f as the opposing wall 4c extends from the lower edge of the window 4n of the extending wall 4g, and on the surface of the elastic piece 4f facing the arrangement space 4a side, there are opposing surfaces 4j (specifically, one opposing surface 4p and the other opposing surface 4q) that abut against the outer surface of the bent portion 1e of the lip groove-shaped steel material 1. And as described above, the second restricting portion 4i (specifically, one second restricting portion 4r and the other second restricting portion 4s) as the second movement restricting portion 4e is formed to protrude continuously from the opposing surface 4j (one opposing surface 4p and the other opposing surface 4q).

[0035] Also, the arrangement space forming portion 4 includes an extension portion 4t that bends and extends from the tip of the extending wall 4g so as to face the first movement restricting portion 4d, and the tip portion of the extension portion 4t becomes the aforementioned side wall inner surface abutting portion 4k.

[0036] Therefore, this mounting portion structure 3 (mounting body 2) corresponds to a relatively large-sized lip portion 1f (lip portion 1c), a medium-sized lip portion 1g (lip portion 1c), and a small-sized lip portion 1h (lip portion 1c). The base wall 4b and the first movement restricting portion 4d are common. For the large-sized lip portion 1f, an extension wall 4g is provided as the opposing wall 4c, and a first restricting portion 4h is provided as the second movement restricting portion 4e (see Fig. 6). For the medium-sized lip portion 1g, an elastic piece 4f (specifically, one opposing surface 4p of the elastic piece 4f) is provided as the opposing wall 4c, and a second restricting portion 4i (specifically, one second restricting portion 4r) is provided as the second movement restricting portion 4e (see Fig. 8). For the small-sized lip portion 1h, an elastic piece 4f (specifically, the other opposing surface 4q of the elastic piece 4f) is provided as the opposing wall 4c, and a second restricting portion 4i (specifically, the other second restricting portion 4s) is provided as the second movement restricting portion 4e (see Fig. 9). However, for the large-sized lip portion 1f, since the elastic piece 4f also abuts against the outer surface of the bent portion 1e of the lip portion 1f, in addition to the extension wall 4g, the elastic piece 4f also functions as the opposing wall 4c (see Fig. 7).

[0037] Next, the operation and effect of the mounting portion structure 3 on the lip groove-shaped steel member 1 having the above configuration, the mounting body 2 provided with the mounting portion structure 3, and the installation structure 6 of the mounting body 2 will be described. The mounting portion structure 3 includes a layout space forming portion 4 that forms a layout space 4a in which one lip portion 1c of the lip groove-shaped steel member 1 is arranged, and an opening 5. Through the opening 5, one lip portion 1c is inserted into the layout space 4a. Here, the layout space forming portion 4 includes a base wall 4b and an opposing wall 4c. By these base wall 4b and opposing wall 4c, the mounting body 2 is prevented from moving in the direction in which the pair of lip portions 1c, 1c of the lip groove-shaped steel member 1 face each other. Further, the layout space forming portion 4 includes a first movement restricting portion 4d and a second movement restricting portion 4e. By these first movement restricting portion 4d and second movement restricting portion 4e, the mounting body 2 is restricted from moving in a direction orthogonal to the bottom wall 1a of the lip groove-shaped steel member 1. In this way, the movement of the mounting body 2 is restricted, and the mounting body 2 is attached to one lip portion 1c of the lip groove-shaped steel member 1.

[0038] Incidentally, the arrangement space forming portion 4 (mounting portion structure 3) also has the following configuration. That is, the arrangement space forming portion 4 is provided on the outer surface of the connecting portion between one side wall 1b and the flange portion 1d in the lip groove-shaped steel material 1, the outer surface of the portion extending from the tip portion of one side wall 1b to the flange portion 1d, or the outer surface of the tip portion of one side wall 1b and the flange portion 1d (in the illustrated embodiment, the outer surface of the portion extending from the tip portion of one side wall 1b to the flange portion 1d), and has a one-side contact portion (in the illustrated embodiment, the portion extending from the base wall 4b to the first movement restricting portion 4d). Then, when the elastic piece 4f constituting the arrangement space forming portion 4 is pushed by one lip portion 1c entering the arrangement space 4a from the opening 5 and elastically deformed, one lip portion 1c is arranged in the arrangement space 4a, and the elastic piece 4f, in the elastically deformed state, the portion from the opposing surface 4j to the second restricting portion 4i of the elastic piece 4f abuts against the tip portion of the bent portion 1e of one lip portion 1c arranged in the arrangement space 4a, and presses one lip portion 1c toward the side of the one-side contact portion (see FIGS. 8 and 9). That is, the arrangement space forming portion 4 includes a one-side contact portion and an elastic piece 4f, and the one-side contact portion and the elastic piece 4f sandwich one lip portion 1c, whereby the attachment body 2 is attached to one lip portion 1c.

[0039] Therefore, according to the mounting portion structure 3 for the lip groove-shaped steel material 1, the mounting body 2 having the mounting portion structure 3, and the installation structure 6 of the mounting body 2, the mounting body 2 can be attached to one lip portion 1c regardless of the bottom wall 1a of the lip groove-shaped steel material 1, and the mounting body 2 can be attached to various lip groove-shaped steel materials 1 without being restricted by the interval between the pair of lip portions 1c, 1c and the interval between the bottom wall 1a and the lip portion 1c. In particular, when the lip groove-shaped steel material 1 is used as a ceiling base material, since the mounting body 2 is attached away from the bottom wall 1a, interference between the screws for fixing the ceiling to the ceiling base material (lip groove-shaped steel material 1) and the mounting body 2 can be avoided.

[0040] Note that the present invention is not limited to the above-described embodiments, and various other modifications are possible. For example, as shown in FIG. 10, in the lip channel steel member 1, the flange portion 1d of the lip portion 1c may be formed in an arc shape instead of a straight line shape.

[0041] Further, in addition to the attachment portion structure 3, the attachment body 2 includes a holding portion 7 for holding wiring and piping materials, a fixing portion 8 to a suspension bolt, and a seat portion 9 for wiring and piping materials for tying up the wiring and piping materials. However, one or more of these may be omitted.

[0042] Also, two sets of opposing surfaces 4j and second restricting portions 4i are provided on the elastic piece 4f, but one set may be provided, or three or more sets may be provided.

[0043] Further, the arrangement space forming portion 4 includes an extending wall 4g and an elastic piece 4f as opposing walls 4c, but one of the extending portion 4g and the elastic piece 4f may be omitted.

[0044] Also, the arrangement space forming portion 4 includes a side wall inner surface contact portion 4k, but this side wall inner surface contact portion 4k may be omitted.
