JP 2007-297860 A Registered Utility Model No. 3164020

  In the bolt body holding mechanism as in Patent Documents 1 and 2, both holding portions (notches) joined to hold the bolt body are formed so as to substantially match the outer shape of the bolt body. That is, the lateral width of the bolt head housing portion of the bolt body is formed to be substantially the same as the two-surface width (minimum width) of the bolt body having a regular hexagonal head. Therefore, when the facing walls are brought close to each other and joined, the bolt body is in a predetermined posture (that is, the bolt head short axis can be fitted into the width of the holding portion, and the bolt head short axis is in the width direction of the holding portion) The side of the bolt body and the side edge that borders the holding portion are in contact with each other, and the bolt head cannot be disposed inside the holding portion. Therefore, when the head of the bolt body is accommodated in the holding portion, both facing walls must be brought close to each other and joined while maintaining the short axis of the bolt head parallel to the width direction of the holding portion. In particular, when an operator works at a high place on the roof, the bolt body so as to maintain the bolt head in a predetermined posture simultaneously with the step of bringing a pair of facing walls into close proximity (or fastening). Since it has to be held by hand, there is a problem that work efficiency is greatly reduced.

  Further, in the conventional bolt body holding mechanism, the facing wall is fastened as it is without the operator noticing that the bolt head is displaced from the predetermined posture and the bolt body is not completely fitted in the holding portion. There was a risk of it. In such a case, since the side edge that borders the holding portion of the facing wall between the facing walls bites the bolt head side surface, the proximity and joining of the facing walls become insufficient. Therefore, for example, in the fixing bracket as in Patent Document 1 or 2, the fixing pressure of the gob portion is insufficient and the fixing bracket is detached from the roof, or the bolt body is easily removed upward from the holding portion. May fall out of the fixing bracket together with the bolt body, which may cause a later accident, which is a big problem.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a bolt body holding mechanism that makes it possible to more easily and stably hold a bolt body between facing walls, and An object of the present invention is to provide a fixture having a bolt body holding mechanism.

And the fourth width (w4) is larger than the minimum distance (s).

  The bolt body holding mechanism according to claim 3 is the bolt body holding mechanism according to claim 2, wherein the fourth width (w2) is larger than the minimum distance (s) and smaller than the maximum distance (t). To do.

  The bolt body holding mechanism according to claim 4 is the bolt body holding mechanism according to any one of claims 1 to 3, wherein the other holding portion has the same shape as one holding portion, The bolt head accommodating portions are partially overlapped with each other, and the overlap width is larger than the minimum width (2 s) of the bolt head and smaller than the maximum width (2 t).

  The bolt body holding mechanism according to claim 5 is the bolt body holding mechanism according to claim 1 or 2, wherein the entire width (w1 + w2) of one bolt head housing portion is larger than the minimum width (2s) of the bolt head. It is smaller than the maximum width (2t), and the total width (w3 + w4) of the other bolt head accommodating portion is larger than the maximum width (2t) of the bolt head.

  The bolt body holding mechanism according to claim 6 is the bolt body holding mechanism according to any one of claims 1 to 5, wherein the bolt head has a regular hexagonal shape, and the minimum distance is the two-surface width of the bolt head. The maximum distance is a half width of the diagonal distance of the bolt head.

  The fixing bracket according to claim 7 is a fixing bracket for connecting the installation body and the folded plate roof, and a pair of divided bodies fastened to each other by fastening means so that the facing walls are close to each other; The holding part for holding the goby part of the folded plate roof by bringing the pair of divided bodies close to each other and the bolt body to which the installation body is attached are provided to hold between the pair of divided bodies. And a bolt holding mechanism according to any one of claims 6 to 6.

  The fixing bracket according to an eighth aspect of the present invention is the fixing bracket according to the seventh aspect, wherein the pair of divided bodies includes an upper wall extending in a separation direction from an upper end of the facing wall and a separation direction from both side ends of the facing wall. And a holding portion is cut out at an edge portion between the facing wall and the upper wall.

  According to the bolt body holding mechanism of the present invention (Claim 1), the first width (w1) of the bolt head accommodating portion of one holding portion is larger than the minimum distance (s) of the bolt head and the bolt head. And the second width (w2) is larger than the maximum distance (t). That is, when the operator manually places the bolt body on one holding part, when the short axis (minimum width) of the bolt head is inclined from the width direction of the holding part, the outer surface of the bolt head is The bolt body rotates around the bolt axis by coming into contact with the side edge of one width (w1) (the outer surface of one facing wall). The bolt head is arranged while rotating in the holding portion in a predetermined posture without being obstructed by the side edge of the second width (w2). Therefore, the bolt body can be easily accommodated in the holding portion so that the bolt head short axis is aligned parallel to the width direction of the holding portion.

According to the further feature (Claim 2) of the bolt body holding mechanism of the present invention, in addition to the above-described effects, the following operational effects are obtained. That is, the bolt head housing part of the other holding part has a third width (w3) facing the first width (w1) and a fourth width (w4) facing the second width (w2), The third width (w3) is larger than the maximum distance (t), and the fourth width (w4) is larger than the minimum distance (s). That is, the relationship between each width and the bolt head shape is expressed by the following equation.
(Formula 1) s <w1 <t
(Formula 2) w2> t
(Formula 3) w3> t
(Formula 4) w4> s
By forming each width of the bolt head receiving part so as to satisfy the above formula, the bolt body is guided to a predetermined posture and easily accommodated in the holding part by a series of operations to bring a pair of facing walls close and join. can do. Therefore, just before the facing wall comes close and the holding part joins, even if the short axis (minimum width) of the bolt head is inclined from the width direction of the holding part between the pair of facing walls, The bolt head can be guided so that the bolt head short axis is aligned parallel to the width direction of the holding portion, and the bolt body can be corrected to a predetermined posture.

  More specifically, since the first width (w1) of one bolt head accommodating portion is smaller than the maximum distance (t) of the bolt head, when the pair of facing walls are close to each other and joined, The side edge on the first width (w1) side that borders the bolt head housing portion (that is, the outer surface of the facing wall) abuts on the side surface of the bolt head that deviates from a predetermined posture, and rotates the bolt body around the bolt shaft. . At this time, both the second width (w2) opposite to the first width (w1) and the third width (w3) facing the first width (w1) are greater than the maximum distance (t) of the bolt head. By being formed large, the side edge on the second width (w2) side that borders one bolt head housing portion and the side on the third width (w3) side that borders the other bolt head housing portion The bolt body can be rotated to a predetermined posture without bringing the side face of the bolt head into contact with any of the edges. On the other hand, when either one of the second width (w2) and the third width (w3) is smaller than the maximum distance (t) of the bolt head, in the state where the pair of facing walls are sufficiently close to each other, Since the edge abuts against and locks the side of the rotating bolt head in the long axis direction, the bolt body cannot be rotated to a predetermined posture, and the bolt head is bitten between the facing walls. It will be crowded. Further, if the first width (w1) and the fourth width (w4) are smaller than the minimum distance (s) of the bolt head, the bolt head cannot be fitted into the holding portion.

  Therefore, by configuring the bolt head accommodating portion of the holding portion facing to each other as described above, the bolt head is guided to a predetermined posture and the holding portion of the holding portion is guided by a series of operations for bringing the pair of facing walls close and joined. The bolt body can be accommodated in the holding portion by correcting the deviation of the posture of the bolt head at the time of joining. That is, according to the bolt body holding mechanism of the present invention, the labor of maintaining the bolt body in a predetermined posture is reduced, and the burden of installation work is reduced. In addition, the bolt head is bitten between facing walls and the installation is poor. Can be prevented.

  According to another feature of the bolt body holding mechanism of the present invention (Claim 3), the fourth width (w2) is formed to be larger than the minimum distance (s) of the bolt head and smaller than the maximum distance (t). As a result, the side edge on the first width (w1) side that borders one bolt head housing portion and the side edge on the fourth width (w4) side that borders the other bolt head housing portion are bolt heads. It is possible to contact the side surface of the part. That is, since the rotational force in the same direction is applied to the bolt head from both one side and the other side, the bolt head can be rotated more reliably to a predetermined posture.

  According to another feature of the bolt body holding mechanism of the present invention (Claim 4), the other holding portion has the same shape as the one holding portion, and the one and the other bolt head housing portions are mutually connected. In the state where the bolt head is held in the bolt head housing portion by partially overlapping, the overlap width is larger than the minimum width (2 s) of the bolt head and smaller than the maximum width (2 t). The moving distance in the width direction of the head is limited within a predetermined overlapping width. That is, it is possible to reduce the looseness of the bolt body in the holding portion.

  According to the fixing bracket of the present invention (Claim 7), the above effect can be exhibited as the fixing bracket by incorporating the bolt body holding mechanism of the present invention. That is, the fixing bracket of the present invention can simplify the connecting operation between the goby portion of the folded plate roof and the installation body. Furthermore, in the fixing bracket, the gob portion can be securely held between the divided bodies, and the bolt body attached to the installation body can be firmly held, so that the installation work of the installation body should be carried out reliably. Is possible.

Folds over the lower edge. That is, the facing wall 111, the upper wall 112, the side wall 113, and the bottom wall 114 constitute a frame structure that can support each other. The first and second bent pieces 112a and 114a and the end and upper and lower edges of the side wall 113 are preferably in close contact with each other in order to reduce the shakiness of the divided body 110. If the upper wall 111 or the bottom wall 114 is in a supporting relationship with each other, the upper wall 111 or the bottom wall 114 may be separated to some extent.

  FIG. 6B shows a cross-sectional shape of the divided body 110 in a side view (cross section BB in FIG. 4A). As shown in FIG. 6B, the upper end of the facing wall 111 and the base end of the upper wall 112 are bent at the edge portion 116. In the edge portion 116, the facing wall 111 is gently raised from the outer surface near the upper end (to the other facing wall 111 side) to form a raised portion 116a. Further, at the edge portion 116, the upper wall 112 is bent downward so as to be gently curved in the vicinity of the proximal end, and a curved portion 116b is formed at an angle where the facing wall 111 and the upper wall 112 intersect. As will be described later, the raised portion 116a and the curved portion 116b are provided on the edge portion 116, so that the goby portion P1 can be more stably sandwiched between the two divided bodies 110. Furthermore, the facing wall 111 is refracted inward at the upper edge of the accommodation opening 118b to form a bent portion 111a.

  Further, FIG. 6C shows a cross-sectional shape of the divided body 110 in a plan view (C-C cross section of FIG. 4B), and the tips of both side walls 113 (that is, opposite to the facing wall 111) The end portion is folded outward at a substantially right angle to increase the strength against bending in the vertical direction to form a third bent piece 113a.

  Next, the holding part 117 that functions as a bolt body holding mechanism and is notched and formed in the edge part 116 between the facing wall 111 and the upper wall 112 of the divided body 110 will be described in detail. When the two divided bodies 110 and 110 ′ are fastened and combined, the holding portion 117 has both facing walls of the pair of divided bodies 100 and 110 ′ that are close to each other with the bolt body 200 for fixing the installation body. 111 can be held or supported. That is, when the facing walls 111 and 111 ′ of the pair of divided bodies 110 and 110 ′ face each other and are combined, the holding portions 117 are joined to form an accommodation space that can hold and support the bolt body 200. In the present embodiment, the holding portion 117 formed on one facing wall 111 and the holding portion 117 formed on the other facing wall 111 are formed with the same size and shape.

  FIG. 7 is a partially enlarged view (front view) of the holding portion 117 formed on the facing wall 111. The holding portion 117 is continuous with the bolt head accommodating portion 117a capable of accommodating the head 201 of the bolt body 200 formed by cutting out in the vicinity of the upper end of the facing wall 111 of the divided body 110, and the bolt head accommodating portion 117a. And a bolt shaft portion insertion portion 117b through which the shaft portion 202 of the bolt body 200 cut out at the base end of the upper wall 112 can be inserted. The bolt shaft portion insertion portion 117b is notched in a semicircular shape (plan view) with a diameter d through which the bolt shaft portion 202 can be inserted, as shown in FIG. The diameter d is preferably set to be slightly larger than the diameter of the bolt shaft portion 202 in order to support the bolt body 200 so as not to rattle.

  As shown in FIG. 7, the holding portion 117 is a convex cutout formed in the facing wall 111 in the front view and capable of accommodating the bolt head 201 and the shaft portion 202. The bolt head accommodating portion 117a is a lower notch having a rectangular width w1 + w2 and height h1 that accommodates the bolt head 201. On the other hand, the bolt shaft insertion portion 117b is a rectangular upper notch having a width d (<w1 + w2) and a height h2 for accommodating the base of the bolt shaft portion 202. And the holding | maintenance part 117 combines these upper notches and lower notches. The height h1 corresponds to the axial thickness of the bolt head 201 so that the head 201 of the bolt body 200 can be accommodated. The height h2 corresponds to the distance between the lower notch and the outer surface of the upper wall 111. Further, the height h2 is set so as to form the upper wall 112 on the bolt head housing portion 117a so as to restrict the axial movement of the bolt head 201 housed in the bolt head housing portion 117a. What is necessary is just to be shortened or extended from the form of FIG.

  The bolt shaft insertion portion 117b is disposed at the approximate center of the facing wall 111. The bolt shaft portion insertion portion 117b has a center line c that matches the center axis of the inserted bolt 200, and is formed with a width d symmetrically from the center line c. On the other hand, the bolt head housing portion 117a has a first width w1 on one side (right side in FIG. 7) extending in a direction orthogonal to the center line c of the bolt shaft insertion portion 117b along the bolt shaft, and the other side. It has a second width w2 (> w1) (left side in FIG. 7) and extends in the left-right width direction with a full width w1 + w2. The left width w2 is larger than the right width w1 by a width Δw. In other words, the convex-shaped holding portion 117 is not symmetrical and extends on the other side by the width Δw. In other words, it arrange | positions so that the center of the bolt head accommodating part 117a may shift | deviate to the side with respect to the centerline c of the bolt shaft part insertion part 117b left-right symmetric.

  In this embodiment, since one holding part 117 and the other holding part 117 have the same shape, the first width w1 of one holding part 117 matches the fourth width w4 of the other holding part 117. In addition, the second width w2 of the one holding portion 117 matches the third width w3 of the other holding portion 117. The side edge on the first width w1 (fourth width w4) side of the facing wall 111 that borders the bolt head housing portion 117a is 117w1 (117w4) and the second width w2 (third width w3). The side edge on the side is defined as 117w2 (117w3).

  Here, the minimum distance from the center of the bolt head 201 to its outer surface is defined as s, and the maximum distance from the center of the bolt head to its outer surface is defined as t. In this embodiment, since the bolt head 201 has a regular hexagonal shape, the minimum distance s is half of the two-face width of the hexagon bolt head, and the maximum distance t is half of the diagonal distance of the hexagon bolt head. (See FIG. 11). In the present specification, the minimum width 2s and the maximum width 2t of the bolt head 201 are also expressed as a short axis and a long axis.

The first width w1 (or the fourth width w4) on the right side in FIG. 7 is formed to be larger than the minimum distance s of the bolt head 201 and smaller than the maximum distance t. On the other hand, the second width w2 (or the third width w3) on the left side is designed to be larger than the maximum distance t. That is, the relational expression between each width and the bolt head shape in the present embodiment is as follows.
(Formula 5) s <w1 = w4 <t
(Formula 6) w2 = w3> t

  Since the bolt head accommodating portion 117a of the holding portion 117 is designed in the above range according to the shape and size of the bolt head 201, the bolt head 201 is fitted in the bolt head accommodating portion 117a in a predetermined posture. Can be guided. That is, when the operator pushes the bolt body 200 into the one holding portion 117 by hand, when the short axis of the bolt head 201 is inclined from the width direction of the holding portion 117, the outer surface of the bolt head 201 is The bolt body 200 rotates around the bolt shaft portion 202 by coming into contact with the side edge 117w1 having one width w1. The bolt head 201 is guided by the side edge 117w1 without being obstructed by the side edge 117w2 of the second width w2, and the one holding portion 117 is in a posture in which the short axis of the bolt head 201 is parallel to the width direction. Fits in.

  In the holding portion 117 of the present embodiment, the first width w1 and the fourth width w4 are slightly larger than the minimum distance s and the second width w2 in order to reduce rattling of the bolt body 200 to be accommodated. The third width w3 is only slightly larger than the maximum distance t. This “slightly large width” is a width that can accommodate the bolt head with a slight difference, and in a broad sense, the minimum distance of the bolt body and the first width and the fourth width are interpreted to be substantially equal. You can also.

  The divided bodies 110 and 110 ′ of this embodiment are obtained by bending (or pressing) and punching a plate-shaped SUS material, but the present invention is limited to the manufacturing method and material of the embodiment. It is not something. For example, a casing having a bent piece can be formed by welding a plurality of SUS plates as in the present embodiment. Further, as a difference between the one divided body 110 and the other divided body 110 ′, there is a fastening nut 119b welded to the inner surface of the facing wall 111, but a fastening hole 119a is formed instead of welding the fastening nut 119c. However, a fastening nut can also be used as a separate body. That is, it is possible to make one divided body 110 and the other divided body 110 'completely the same shape. Alternatively, in the present embodiment, the one divided body 110 and the other divided body 110 ′ are the same size and shape, but it is also possible to change one dimension in accordance with the application or the like.

  FIG. 8 is a side view of the installation structure 10 in which the fixing bracket 100 is disposed on the folded plate roof P. FIG. As shown in FIG. 8, the folded plate roof P is provided with a goby portion P1 formed by folding a metal roof. This goby portion P1 extends from the top of the folded plate roof P, and bulges laterally at the top. Moreover, the goby part P1 is a long body formed along the folded plate roof, and extends in a direction penetrating through the notch (accommodating opening 118b) of each side wall 113 of the fixture 100. And the fixing metal fitting 100 is being fixed to the folded-plate roof P by pinching this goby part P1 between the facing walls 111 of a pair of division body 110,110 '. That is, the facing walls 111 of the pair of divided bodies 110 and 110 ′ are close to each other, and the nail part P <b> 1 of the folded plate roof P is held by the holding part 118. More specifically, the root of the goby portion P1 is pinched by a pair of concave and convex pinching pieces 118a, and the swollen upper portion of the goby portion P1 is placed inside the pair of divided bodies 110 and 110 ′ via the accommodation opening 118b. It is arranged.

  Further, according to FIG. 8, the raised portions 116 a protruding from the outer surfaces of the pair of divided bodies 110, 110 ′ are in contact with each other at the upper ends of the facing walls 111. That is, the base of the goby portion P1 is pinched by the pinching piece 118a with the raised portion 116a as a fulcrum so that the facing walls 111 are not in surface contact with each other. Therefore, the force is concentrated on the pinching piece 118a without dispersing the force on the entire facing wall 111, and the goby portion P1 is pinched more firmly. Further, the degree of contact of the raised portion 116a can be visually recognized from above by the curved portion 116b provided on the edge portion 116.

  FIG. 9A is a longitudinal sectional view taken along the center of the bolt body 200 of the installation structure 10 of FIG. 8, and FIG. 9B is a transverse sectional view thereof. As shown in FIG. 9 (a), the fastening bolt 119c passes through the fastening hole 119a of one divided body 110 and is screwed to the fastening nut 119b of the other divided body 110 ', thereby dividing the divided bodies 110, 110'. Is concluded. And as shown to Fig.9 (a) and (b), it hold | maintains by the both holding parts 117 which one and other division body 110,110 'joined so that the axial part 202 of the bolt body 200 may face upwards. . The head portion 201 of the bolt body 200 is housed in the bolt head housing portion 117a, and the bolt shaft portion 202 penetrates the bolt shaft portion insertion portion 117b. The bolt body 200 is supported and held between the divided bodies so that 201 faces vertically upward. At this time, one and the other bolt shaft portion insertion portion 117b are joined so as to match each other to form a circular hole having a diameter d (<s) on the top surface, and the edge (one and the other of the circular holes) The inner surface of the upper wall 112 engages with the bolt head 201 to limit the upward movement of the bolt body 200. Further, at the lower edge of the bolt head accommodating portion 117a, the end surface of the facing wall 111 supports the bolt head 201 from below. That is, the holding portion 117 restricts the axial movement of the bolt head 201 by the end face of the facing wall 111 and the inner surface of the upper wall 112 and holds the bolt body 200 so as not to be pulled up and down.

  FIG. 10 is a schematic view showing a form in which the holding portions 117 (bolt head accommodating portions 117a) of one divided body 110 and the other divided body 110 'in FIG. 9B are joined. In FIG. 10, one bolt head housing portion 117a is represented by a solid line, the other bolt head housing portion 117a is represented by a dotted line, and the bolt body 200 is represented by a virtual line. One and the other holding part 117 partially overlap each other. The width of the overlapping portion of one bolt head housing portion 117a and the other bolt head housing portion 117a is w1 + w4. Moreover, the full width of the joined bolt head accommodating part 117a is w2 + w4. In other words, in the joined one and other holding parts 117 in FIG. 10, the bolt shaft insertion part 117b is joined in a substantially matched manner, whereas the bolt head housing part 117a is joined with being shifted in the width direction. ing.

  11 is a cross-sectional view taken along line EE in FIG. According to FIG. 11, in the fastening state of the divided bodies 110 and 110 ′ (or the holding state of the bolt body 200), the bolt head 201 of the bolt body 200 has a two-surface width 2 s in the width direction of the holding portion 117. And it has diagonal distance 2t along the opposing axis a orthogonal to this. That is, the short axis of the bolt head 201 is held in a posture parallel to the width direction of the holding portion 117 so that the minimum width side surface of the bolt head 201 can be fitted into the width of the bolt head housing portion 117a. ing. The first width w1 and the fourth width w4 are larger than the minimum distance s of the bolt body 200 and smaller than the maximum distance t. On the other hand, the second width w2 and the third width w3 are larger than the maximum distance t of the bolt body 200.

  In this embodiment, the overlap width of the bolt head accommodating portion 117a of the one and the other holding portions 117 is larger than the minimum width (two-surface width) 2s of the bolt head 201, and the maximum width is the bolt head. The maximum width (diagonal distance) of 201 is smaller than 2t. That is, the side edges 117w1 and w4 of the first width w1 and the fourth width w4 are arranged close to the two side surfaces of the bolt head 201 in the width direction, respectively. That is, when a rotational force is applied to the bolt body 200, the end surfaces of the one and other side edges 117w1 and 117w4 are disposed so that the two side surfaces of the bolt head 201 can be locked from both sides. In the holding unit 117. Therefore, the bolt body 200 is supported and held by the joined holding portion 117 so as not to rotate.

  In this embodiment, as shown in FIGS. 10 and 11, the overlapped portion of the bolt head accommodating portion 117 a of the joined holding portion 117 is set to be substantially equal to the minimum width (two-surface width) of the bolt body 200. (S to w1, w4). Thereby, both the end surfaces of the one and the other edge portions 117w1 and 117w4 can be engaged with both side surfaces of the bolt head 201, and rattling in the rotation direction of the bolt body 200 is reduced.

  Hereinafter, with reference to FIG. 12, a method for constructing the installation structure 10 for attaching the installation body by attaching the fixing bracket 100 to the seam P1 of the folded plate roof P will be described.

  First, as shown in FIG. 12 (a), with the facing wall 111 of one divided body 110 and the other divided body 110 ′ facing each other, between the one divided body 110 and the other divided body 110 ′. The bolt body 200 is disposed, and the upper part of the swollen portion P1 that is swollen is brought close to the divided body 110, 110 ′ through the housing opening 118b of the clamping unit 118 along the opposing axis. At this time, by visually observing the slit 123a and the notch 123b of the center aligning portion 123 provided on the bottom wall 114 from the opening 115 or the confirmation window 122, by aligning with the ruled line arbitrarily marked on the folded plate roof P The fixing bracket 100 can be easily aligned along a predetermined direction.

  Next, as shown in FIG. 12B, the alignment shaft 121 (or alignment hole 120) of one divided body 110 is changed to the alignment hole 120 (alignment shaft 121) of the other divided body 110 ′. Insert. In this manner, the divided bodies 110 and 110 ′ are brought closer together with the facing positions thereof aligned, the fastening bolt 119c is inserted into the fastening hole 119a of one divided body 110 from the opening 115, and the shaft portion of the fastening bolt 119c is inserted into the other side. Screw into the fastening nut 119b of the divided body 110 ′. Then, the bolt body 200 is disposed and held in the holding portion 117 so that the raised portions 116a of the edge portions 116 of both the divided bodies 110 and 110 'are brought into contact with each other.

  In this state where the one and the other facing walls 111 are joined to each other, the fastening nut 119b is tightened with a tool or the like, and the base of the goby portion P1 is clamped by the pair of clamping pieces 118a, thereby fixing the fixing bracket 100. It fixes to the goby part P1 of the folded-plate roof P. FIG. At this time, the fastening state of the fastening means 119 can be confirmed by observing the inside of each of the divided bodies 110 and 110 ′ through the confirmation window 122 from above. Further, the contact state of the pair of facing walls 111 (the raised portions 116 a) or the accommodated state of the bolt body 200 can be viewed from above via the curved portion 116 b of the edge portion 116. In this way, the installation of the installation structure 10 on the folded plate roof P is completed. Then, a desired installation body (for example, the solar panel installation device Q) can be fixed to the installation structure 10 via the bolt body 200 located at the top of the fixture 100.

  It should be noted that the method described here is only one example, and it goes without saying that a person skilled in the art can implement the method by changing the order or adding other steps or omitting other steps. Nor.

  FIGS. 13A to 13C show a predetermined posture (that is, the minimum width of the bolt head) by guiding the bolt head 201 of the bolt body 200 in a series of operations for bringing the pair of facing walls 111 close to each other and joining them. FIG. 6 is a schematic diagram showing each process of the bolt body holding mechanism that is aligned in the direction perpendicular to the opposing axis of the facing wall and fitted into the holding portion 117. In particular, the bolt body holding mechanism functions to correct the posture even when the bolt head 201 is deviated from a predetermined posture immediately before joining (or fastening) the pair of facing walls 111. .

  In FIG. 13A, in the initial posture of the bolt body 200, the bolt head 201 is disposed in a direction in which the diagonal line is orthogonal to the opposing axis of the facing wall 111. In this state, the one and the other divided bodies 110 and 110 'are brought close to each other so that the bolt shaft portion 202 is disposed in the bolt shaft portion insertion portion 117b.

  Next, as shown in FIG. 13 (b), when the two facing walls 111 are brought relatively close to each other, the first width w1 of the one and the other bolt head housing portion 117a and (at the diagonal position of the first width). Since the fourth width w4 is smaller than the maximum distance t of the bolt head 201, the side edge 117w1 and the side edge 117w4 (that is, the outer surface of the facing wall 111) bordering the one and other bolt head accommodating portions 117a are predetermined. The bolt body 200 is brought into contact with both sides (opposite outer sides) of the bolt head 201 displaced from the posture almost simultaneously, and the bolt body 200 is rotated around the bolt axis (or the center line c) in the arrow direction. At this time, both the second width w2 opposite to the first width w1 and the third width w3 at the diagonal position of the second width w2 are formed to be larger than the maximum distance t of the bolt head. The outer edge of the bolt head 201 is not brought into contact with any one of the side edge 117w2 that borders one bolt head housing portion 117a and the side edge 117w3 of the other bolt head housing portion 117a. The bolt body 200 can be rotated to a predetermined posture by being guided by 117w1 and 117w4.

  Then, as shown in FIG. 13C, the bolt head 201 is guided by the side edges 117w1 and 117w4 of both facing walls 111, and the diagonal line (long axis) of the bolt head 201 is aligned along the opposing axis. Thus, the two facing walls 111 substantially come into contact with each other in the vicinity of the edge portion 116. In this arrangement state, even if a rotational force is applied to the bolt body 200, the bolt head 201 is locked by the end surfaces of the side edges 117w1 and 117w4 of both divided bodies 110 and 110 '. That is, the bolt body 200 is fitted and held in the holding portion 117 in a predetermined posture in a non-rotating state.

  For ease of explanation, the bolt head 201 is arranged to have a maximum width 2t in the width direction of the holding portion 117, but when the bolt head 201 is deviated from a predetermined posture, that is, If the bolt head 201 does not have the minimum width 2 s in the width direction of the holding portion 117, the bolt body holding mechanism operates in the same manner as described with reference to FIGS. And function. Or, in the initial posture of the bolt head 201, when the short axis of the bolt head 201 is parallel to the width direction of the holding portion 117, or when the short axis is slightly inclined from there, naturally, the edge of the facing wall The bolt head 201 is guided into the bolt head accommodating portion 117a without contacting any of the portions 117w1 and 117w4. Alternatively, it is possible for the operator to bring the pair of facing walls 111 close together in a state where the bolt body 200 is first accommodated in one holding portion 117, but the posture of the bolt body 200 immediately before joining the facing walls 111. The posture can be corrected in the case of deviation.

  The shape of the bolt head that can be used in the bolt body holding mechanism of the present invention is not limited to the regular hexagon described above. That is, hexagon bolts are most commonly used to fix the installation body, but the bolt body holding mechanism of the present invention has the same function even if a bolt body having a head shape other than the hexagon bolt is used. Can be demonstrated.

  For example, FIGS. 14A to 14C are views showing a process of housing a bolt body 200 ′ having a square bolt head 201 ′ in the bolt head housing portion 117 a. In this bolt head 201 ', the maximum width corresponds to the diagonal distance, and the minimum width corresponds to the two-surface width. And each width | variety of the bolt head accommodating part 117a was formed according to this. Since each process is the same as FIGS. 13A to 13C, detailed description thereof will be omitted. However, as shown in FIGS. 14A to 14C, the outer surface of the bolt head 201 ′ has side edges 117w1 and w4. , The bolt head 201 ′ is rotated, and the short axis of the bolt head 201 ′ is guided so as to face the width direction of the bolt head accommodating portion 117a.

  FIGS. 15A to 15C are views showing a process of housing the bolt body 200 ″ having the oval bolt head 201 ″ in the bolt head housing portion 117a. The bolt body 200 ″ is a shaft body in which a shaft is fixed to an elliptical disk having a predetermined thickness. In the bolt head 201 ″, the maximum width corresponds to the major axis diameter, and the minimum width corresponds to the minor axis. It corresponds to the diameter. And each width | variety of the bolt head accommodating part 117a was formed according to this. Similarly to the embodiment of FIGS. 13 and 14, as shown in FIGS. 15A to 15C, the bolt head 201 ″ is brought into contact with the outer edges 117w1 and w4 of the bolt head 201 ″. The bolt head 201 ″ was rotated and guided so that the short axis of the bolt head portion 201 ″ was directed in the width direction of the bolt head housing portion 117 a.

  In other words, the bolt body holding mechanism according to the present invention has each width of the bolt head housing portion as long as the bolt head has a planar shape having a minimum distance s (short axis) and a maximum distance t (long axis). By setting, the bolt head can be guided and accommodated in the holding portion. That is, the bolt body in the present invention means a shaft body having a shaft portion that can fix the installation body and a head portion that can be housed in the bolt head housing portion, and includes a so-called “non-standard bolt”. It is.

  FIG. 16 shows a form in which an example installation body is attached to the installation structure 10 of one embodiment of the present invention. The installation body is a solar panel installation device Q, and includes a rail body Q1, a support body Q2 disposed on the rail body Q1, and a solar panel Q3 supported by the support body Q2. The rail body Q1 is arranged on the bolt shaft portion 202 of the bolt body 200 extending from the top of the fixing metal fitting 100 attached to the seam portion P1 of the folded plate roof P via the fixing hole formed therein, and the bolt shaft portion 202 The installation body is fixed to the fixing bracket 100 by screwing the nut onto the fixing bracket 100. That is, in FIG. 16, the folded-plate roof P and the installation body Q are connected by the fixing metal fitting 100 (or installation structure 10) of one Embodiment of this invention. In addition, the solar panel installation apparatus Q of FIG. 16 is only an example of an installation body, and you may attach any member on a roof as needed.

  Hereinafter, the operation and effect of the fixture 100 (or the bolt body holding mechanism) according to the embodiment of the present invention will be described.

  In the fixing bracket 100 according to the embodiment of the present invention, the first width w1 of the one bolt head housing portion 117a is larger than the minimum distance s of the bolt head 201 and smaller than the maximum distance t, and the second width w1. The width w2 is formed larger than the maximum distance t. The third width w3 of the other bolt head housing portion 117a is larger than the maximum distance t, and the fourth width w4 is larger than the minimum distance s and smaller than the maximum distance t. Therefore, as described with reference to FIG. 13, when the bolt body 200 is accommodated in the holding portion 117 with the pair of facing walls 111 brought close to each other, the short axis (the outermost axis) of the bolt head 201 is interposed between the pair of facing walls 111. The bolt head 201 is arranged so that the minor axis of the bolt head 201 is aligned in parallel with the width direction of the holding portion 117 even when the small width is inclined from the width direction of the holding portion 117. , And the bolt body 200 can be reliably accommodated in the holding portion 117 by rotating it to a predetermined posture in which the bolt body 200 can be fitted in the holding portion 117. At this time, since the rotational force is applied to the bolt head 201 from both one side and the other side by the side edges 117w1 and 117w4, the bolt head 201 can be rotated more reliably to a predetermined posture.

  Furthermore, the other holding portion 117 has the same shape as the one holding portion 117, and the one and other bolt head accommodating portions 117a and 117a partially overlap each other, and the overlapping width (w1 + w4) is It is larger than the minimum width 2s and smaller than the maximum width 2t. Thereby, in the state which hold | maintained the bolt head 201 in the bolt head accommodating part 117a, the movement distance to the width direction of the bolt head 201 is restrict | limited within predetermined overlap width (w1 + w4). In particular, in this embodiment, since the overlap width (w1 + w4) and the minimum width 2s of the bolt head 201 are substantially equal (or the overlap width is slightly wider than the minimum width), the bolt body 200 is within the holding portion 117. It effectively reduces rattling.

  Therefore, according to the bolt body holding mechanism of this embodiment and the fixing bracket 100 including the mechanism, the bolt body 200 is guided and held to a predetermined posture by a series of operations for bringing the pair of facing walls 111 close to each other and joining them. The displacement of the posture of the bolt head 201 can be corrected so as to be accommodated in the portion 117. Then, it is possible to reduce the burden of installation work by eliminating the trouble of maintaining the bolt body 200 in a predetermined posture, and to prevent the installation of poor installation by biting the bolt head 201 between the facing walls 111.

  Although the bolt body holding mechanism and the fixture 100 of the embodiment of the present invention have been described, the present invention is not limited to the above embodiment. For example, as the simplest configuration, if the first width w1 and the second width w2 of the bolt accommodating portion of the holding portion of at least one facing wall satisfy Expressions 1 and 2 (corresponding to claim 1 of the present invention), the bolt There is a remarkable effect that the body can easily be fitted into one holding part, which is not found in the prior art, and can be one solution to the problem of the present invention. Furthermore, if it is the range which satisfy | fills Formula 1-Formula 4 mentioned above, a bolt body holding | maintenance mechanism functions so that the attitude | position of a bolt body can be corrected at the time of joining of a facing wall similarly to one Embodiment. That is, in this invention, the 1st-4th width | variety of a bolt head accommodating part is not limited to the range of Formula 5 and 6 of one Embodiment. For example, with reference to FIGS. 17 to 19, another example (modified example 1) in which the third width w3 and the fourth width w4 are changed from the above embodiment will be described.

(Modification 1)
As shown in FIGS. 17 and 18, the first width w1 is formed to be larger than the minimum distance s of the bolt head 201 and smaller than the maximum distance t. On the other hand, the second width w4, the third width w3, and the fourth width w4 are designed to be larger than the maximum distance t. That is, the relational expression between each width and the bolt head shape in the modification is as follows.
(Formula 7) s <w1 <t
(Formula 8) w2, w3, w4> t

  In FIG. 18, the bolt head 201 is arranged in a predetermined posture in which the minor axis of the bolt head 201 faces the width direction in the bolt head housing portion 117a. At this time, in order to stop the rotation of the bolt body 200, the side edge 117w1 having the first width w1 is disposed in the vicinity of the outer surface of the bolt head 201. That is, when a rotational force is applied to the bolt body 200, two corners of the side edge 117w1 end surface (that is, the inner surface of the facing wall and the edge of the outer surface) can come into contact with one side surface of the bolt head 201. is there. More specifically, when the bolt head 201 tries to rotate clockwise, the outer surface of the bolt body head 201 comes into contact with the corner of the side wall 117w1 end surface on the facing wall inner surface side (left side), while When trying to rotate clockwise, the outer side surface of the bolt body head 201 comes into contact with the corner on the outer surface side (right side) of the facing wall. That is, since the first width w1 is smaller than the maximum distance t of the bolt head 201, the corners of the bolt body 201 cannot pass through the first width w1, and thus the bidirectional rotation of the bolt body 200 is limited. . Therefore, also in this modification, the bolt head 201 is supported and held in the holding portion 117 so as not to rotate, as in the above-described embodiment.

  FIGS. 19A to 19C show the bolt body holding mechanism in a predetermined posture by guiding the bolt head 201 (that is, the direction in which the minimum width of the bolt head is orthogonal to the opposing axis of the facing wall). FIG. 11 is a schematic diagram showing each step of being aligned and fitted into a holding portion 117.

  In FIG. 19A, as in FIG. 13A, in the initial posture of the bolt body 200, the bolt head 201 is arranged such that the diagonal line is perpendicular to the proximity direction (opposite axis) of the facing wall 111. Yes. In this state, the one and the other divided bodies 110 and 110 'are brought close to each other so that the bolt shaft portion 202 is disposed in the bolt shaft portion insertion portion 117b.

  Next, as shown in FIG. 19B, when the two facing walls 111 are brought relatively close to each other, the first width w1 of one bolt head housing portion 117a is smaller than the maximum distance t of the bolt head 201. The side edge 117w1 that borders the one bolt head accommodating portion 117a abuts on one side surface of the bolt head 201 that is deviated from a predetermined posture, and the bolt body 200 is bolted in the arrow direction (or center line c). Rotate around. At this time, both the second width w2 opposite to the first width w1 and the third width w3 at the diagonal position of the second width w2 are formed to be larger than the maximum distance t of the bolt head. Without bringing the outer surface of the bolt head 201 into contact with either the side edge 117w2 that borders one bolt head housing portion 117a and the side edge 117w3 that borders the other bolt head housing portion 117a, The bolt body 200 can be rotated to a predetermined posture (see FIG. 19C).

  That is, if the first width w1 is formed so as to be able to contact at least the side surface of the bolt head 201, the bolt head 201 is guided at the time of approaching and joining the facing wall 111, and the bolt body 200 is in a predetermined posture. It can be accommodated in the holding part 117. This means that the second width w2, the third width w3, and the fourth width w4 can be extended to the left and right ends of the facing wall 111 (or part of both side walls 113). Even in such a case, as described with reference to FIG. 18, both ends of the bolt head 201 can be locked at the end face of the side edge 117 w 1. The body 200 is held in the holding portion 117 in a non-rotating state.

(Modification 2)
Further, the bolt body holding mechanism of the present invention is not limited to the fixing metal fitting 100 of the above-described embodiment, and can be adopted for various fixing metal fittings. For example, in place of the bolt support portion (15) or the bolt holding recess (13) of the fixing metal fitting of Patent Document 1 or 2, the effect of the present invention can be achieved by adopting the bolt body holding mechanism of the present invention. Is possible. Therefore, the fixing bracket of the present invention can take various modes as long as those skilled in the art can assume.

  The present invention is not limited to the above-described embodiments and modifications, and can be implemented in various modes as long as they belong to the technical scope of the present invention.
