And if necessary, as shown in FIG. 11D, the hanging tool 52 is attached to the upper end of the band 53 in the figure by hooking the through hole 531 of the band 53 to the claw part 523 of the hanging tool 52. In this manner, for example, by passing a bolt (not shown) through the bolt through hole 524 of the hanger 52, the pipe 5P can be suspended from the ceiling of the building, for example.

However, in the suspension structure shown in FIGS. 10A, 10B, and 11A to 11D, since it is necessary to bend at least three portions of the two covering

pieces

512 and 513 and the band 53, there are many bent portions and the construction time is long. There is a problem that it takes. Further, as shown in FIGS. 11C and 11D, the two

cover pieces

512 and 513 are bent, and the claw portion 514 is deformed into a flat state so that the

cover pieces

512 and 513 can be sufficiently bent. Since it was difficult to do it with bare hands, a tool was necessary. Moreover, it was necessary to work with both hands.

-Overview-
The present invention will be described by taking an embodiment. The fastener 1 of this embodiment is attached with respect to the band 2 used when attaching a to-be-supported object to a structure. As this fastener 1, the thing of the 2nd form of the 1st fastener 1a shown in FIG. 1 and the 2nd fastener 1b shown in FIG. 2 is used. The 1st fastener 1a can also be attached to the 2nd fastener 1b with respect to the band 2 shown in FIG. In particular, as shown in FIGS. 8A, 8 </ b> B, and 9, the second fastener 1 b is attached to the band 2 when the structure is supported using a bolt.

The structure includes, for example, elements constituting the main part of the building (for example, walls, ceilings, floors, columns, beams, roofs) or elements attached to the building (for example, water pipes, drain pipes, gas pipes, Oil supply piping, electrical wiring support members, furniture, handrails, ladders, doors). Further, not only ground structures but also underground structures (for example, basements, tunnels, manholes) are included in the structures. Various structures other than buildings (for example, moving objects such as vehicles, ships, and aircraft) are also included in the structure.

The supported objects include, for example, continuous bodies such as pipes, electrical wiring, electrical wiring supports, suspended ceiling beams, etc., and single bodies (such as lighting equipment, air conditioning equipment, information display devices, speakers) Non-continuous). The supported object of this embodiment is a metal pipe provided with a layer of heat insulating material on the outer periphery.

-band-
The band 2 has a plurality of through holes 21 formed in the longitudinal direction in the same manner as conventionally used. The band 2 is made of metal (specifically, steel strip). Since it is wound around the supported object P, the thickness of the band 2 is set so as not to hinder bending. As shown in FIGS. 3A and 3B, the width and thickness dimensions of the band 2 are constant in the longitudinal direction. The plurality of through holes 21 are formed at regular intervals in the longitudinal direction. Each through hole 21 is an oval hole formed in the width direction of the band 2. Since the band 2 has a constant width dimension and the plurality of through holes 21 are formed at regular intervals in the longitudinal direction, the long band 2 can be rolled up. Thus, by making the band 2 into a roll shape, the band 2 can be carried to the construction site while being in a roll shape, and can be used after being cut into a required longitudinal dimension at the construction site. The band 2 thus formed is advantageous in that the degree of freedom of processing at the construction site is high.

When this band 2 is wound around a supported object P such as a pipe, as shown in FIG. 6A, for example, a portion 2x attached to a ceiling or a wall and the opposite bent along the supported object P The side portion 2y overlaps twice. The fastener 1 is arrange | positioned in the part which this band 2 overlapped like the past.

In addition, the shape of the through-hole 21 is not limited to the oval shape of this embodiment. For example, various shapes such as a circle and a rectangle can be used. In addition, a plurality of through holes 21 can be formed side by side in the width direction of the band 2. Moreover, although the band 2 of the present embodiment is made of metal, it can be made of resin or cloth. Moreover, although the edge 2 of the width direction of the band 2 of this embodiment was linear, it can also be set as the shape which wavy the edge, for example.

-First fastener-
Regarding the fastener 1, first, the first fastener 1a will be described. The first fastener 1a is made of metal (specifically, steel plate). Since the 1st fastener 1a can be formed by cutting and bending a steel plate, it can be manufactured easily. The first fastener 1 a includes at least a base portion 11, a bent portion 12, and a protrusion 13. When the first fastener 1 a is used, the bent portion 12 is locked to the base portion 11. A locking mechanism for this locking will be described later.

The base 11 has a base main body 111 that is a part facing one side of the band 2 (the lower side in FIG. 1B) when attached to the structure. As shown in FIG. 1A, the base body 111 is rectangular in front view. The illustrated horizontal dimension of the rectangle (specifically, the dimension between the inner surfaces of the bent portion 12 and the locking rising piece 112) is a dimension that is equal to or larger than the width dimension of the band 2. Further, the illustrated vertical dimension of the rectangle is smaller than the distance between the centers of the two through holes 21 adjacent in the longitudinal direction of the band 2. As shown in FIG. 1B, the base main body 111 is a flat plate having a constant thickness.

The bent portion 12 is a portion raised from one edge of the base 11 (more specifically, the base main body 111) to the other surface (upper side surface in FIG. 1B) of the band 2 at the time of attachment. The bent portion 12 of the present embodiment is formed at one end edge 111a on the base body 111 in FIGS. 1A and 1B and is raised upward from the base body 111 in FIG. 1B. The bent portion 12 includes a bent portion main body 121 having a base end connected to the base main body 111 and having a constant width dimension, and a tongue piece 122 protruding from the distal end of the bent portion main body 121 and narrower than the bent portion main body 121. Have The tongue piece 122 functions as a locking portion for the base portion 11 as a part of a locking mechanism described later. In the initial state (that is, the state before folding), the base portion 11 and the base end portion of the bent portion 12 intersect at a right angle as shown in FIG. 1B. The bent portion 12 can be made to face the other surface of the band 2 by being folded with respect to the base portion 11.

The bent portion 12 has an inflection portion 123. The inflection portion 123 is formed in the bent portion main body 121 and bends the distal end portion 12b of the bent portion 12 with respect to the proximal end portion 12a. Specifically, as shown in FIG. 1B, the bent portion 12 is a base portion of the distal end side portion 12b with respect to a direction extending with respect to the base portion 11 (base portion main body 111) of the proximal end side portion 12a before being folded back. 11 (base body 111) extends in a direction closer to the locked portion (through hole 112a) located on the base 11 side in the locking mechanism with the inflection portion 123 as a boundary. . The inflection portion 123 is a portion where the bent portion 12 is bent with a certain curvature.

The bending portion 123 is located farther from the base portion 11 than the base end portion 12a and the tip end portion 12b of the bent portion 12 in a state where the bent portion 12 is bent as shown in FIG. 4A. The bent portion 12 in the state is convex. The inflection angle of the inflection portion 123 is 120 ° in the present embodiment, but is not limited to this and can be implemented at various inflection angles. The inflection angle can satisfy both the viewpoint of ease of putting the band 2 into the space between the base 11 and the bent portion 12 (see FIG. 5A) and the viewpoint of ease of folding operation of the bent portion 12. It is desirable to decide on. The range of the inflection angle is desirably 90 ° or more and less than 180 °, and more desirably 100 ° or more and 140 ° or less.

Further, the inclination angle of the distal end portion 12b with respect to the bent portion 12 with respect to the base portion 11 is 30 ° in this embodiment with respect to the bent portion 123. Also regarding this, it is not limited to the angle of this embodiment, It can implement at various angles. This angle is desirably 20 ° or more and 40 ° or less.

As shown in FIG. 4B, the inflection portion 123 is engaged with the locking portion (the tongue piece 122), which will be described later, with respect to the locked portion (through hole 112a), as shown in FIG. 4B. Deforms so that the inflection angle is widened. When the folding part 12 starts to be folded back, as shown in FIG. 4A, the locking part (tongue piece 122) does not interfere with the locked part (through hole 112a). Thereafter, by deforming so as to widen the angle of the inflection portion 123, as shown in FIG. 4B, the locking portion (tongue piece 122) is locked to the locked portion (through hole 112a). Due to the presence of the bent portion 123, the bent portion 12 is simply formed in a flat plate shape, and the bent portion is compared with a configuration in which the bent portion 12 extends straight from the one end edge 111a of the base body 111. Since the front end side of 12 is inclined in a direction to be bent, the bent portion 12 is easily folded back. Moreover, since the amount of protrusion of the bent portion 12 from the base portion 11 can be suppressed in the state before the folding is performed, the bending portion 12 is bent at the inflection portion 123, so that a plurality of fasteners can be stored. It is not bulky and easy to manage.

In this embodiment, the inflection part 123 is formed at one place in the bent part 12. However, the present invention is not limited to this, and the inflection portion 123 may be formed at a plurality of locations. In addition, the inflection part 123 may be formed by bending the bent part 12 or may be formed by bending. Furthermore, the entire bent portion main body 121 or the entire bent portion 12 may be curved, and the entire bent portion may be the inflection portion 123.

-Protrusions-
In the base body 111, the protrusion 13 is located on the outer side in the longitudinal direction of the band 2 from the edge 12c of the bent portion 12 when the bent portion 12 is bent (on the side away from the bent portion 12, as shown in FIG. 1A). (Upper side and lower side). Two protrusions 13 are formed on the upper and lower ends of the base main body 111 in FIG. When the plurality of through holes 21 are formed side by side in the width direction of the band 2, the protrusions 13 can also be formed side by side. The protrusion 13 is raised from the upper and lower end edges 111 c of the base body 111 in FIG. 1A on the other surface side of the band 2, that is, in the same direction as the bent portion 12. However, the position at which the protrusion 13 is raised from the base body 111 is not limited to the end edge (such as the upper and lower edges 111c on FIG. 1A) in the base body 111. For example, as in the second fastener 1b described later, The protrusion 13 can be raised at a position other than the edge of the base body 111.

The projection 13 penetrates the through hole 21 of the band 2 when attached. In the present embodiment, with respect to the vertical dimension on FIG. 1A, the vertical dimension of the bent portion 12 (dimension between the opposing edges 12c) is smaller than the vertical dimension between the two opposing protrusions 13. For this reason, even when the bent portion 12 is folded back, the bent portion 12 is positioned inside the two protrusions 13, so that the protrusion 13 does not interfere with the bent portion 12. For this reason, in-situ processing such as turning back the protrusion 13 to avoid interference is unnecessary, and the construction can be performed simply by passing the protrusion 13 through the through hole 21 of the band 2.

For example, although it is necessary to form a through hole (through hole such as the long hole 125 shown in FIGS. 2B and 2D) or a cutout through which the projection 13 passes through the bent portion 12, the folded portion 12 that is folded back in plan view. The protrusion 13 can also be formed at the overlapping position. In this embodiment, even when the bent portion 12 is folded back, the protrusion 13 passes through the through hole and the notch, so that the protrusion 13 can be prevented from interfering with the bent portion 12 as in the present embodiment.

In the present embodiment, the interval between the two protrusions 13 and the formation interval of the through-hole 21 of the band 2 coincide with each other. However, the present invention is not limited to this, and the through-hole of the band 2 is larger than the interval between the two protrusions 13. It is also possible to reduce the formation interval of 21 (for example, 2: 1). When the band 2 is wound around the supported object (pipe) P, the attachment position of the fastener 1 to the band 2 can be selected finely when the interval between the through holes 21 of the band 2 is small. It can correspond to the supported object (pipe) P.

Further, the edge 12c facing the protrusion 13 in the bent state in the bent portion 12 is located on the rear side in the direction in which a load is applied with respect to at least one of the protrusions 13 when the bent portion 12 is bent. It is in a position where it can contact. In the present embodiment, there is a slight gap between the edge 12 c of the bent portion 12 and the protrusion 13. This positional relationship is effective when the protrusion 13 is positioned above and the bent portion 12 is positioned below. The reason will be described below.

For example, when the supported object (pipe) P is suspended from the ceiling C as shown in FIG. 6A, the left side of FIG. 6A out of the band 2 that is doubled at the portion corresponding to the fastener 1 (1a). A downward force F that tends to slide downward from the portion 2x suspended from the ceiling due to the load of the supported object (pipe) P is applied to the portion 2y positioned at the position. As is clear from FIG. 6C, this downward force F is also applied to the protrusion 13. For this reason, the protrusion 13 is deformed downward. In FIG. 6C, the bent portion 12 is positioned below the upper protrusion 13. For this reason, when the protrusion 13 is slightly deformed and comes into contact with the end edge 12c of the bent portion 12, the downward force F is applied to the bent portion 12 at the contact portion T on the rear side in the direction of the force. I can support it. Therefore, the protrusion 13 reinforced by the bent portion 12 that abuts can counter the downward force F.

As shown in FIG. 6C, the reinforcement is performed by extending the bent portion 12 in a substantially vertical direction while the protrusion 13 extends in a substantially horizontal direction at the time of attachment. Thus, since the protrusion 13 and the bent portion 12 are in a positional relationship (in the present embodiment, they are in a substantially vertical relationship), the protrusion against the force acting in the longitudinal direction of the band 2 (downward force F) 13 can be reinforced by the bent portion 12. The positional relationship in which the protrusion 13 is reinforced by the bent portion 12 in this way is limited to the case where the protrusion 13 is positioned above and the bent portion 12 is positioned below. The position with respect to is not particularly relevant.

-Locking mechanism-
The 1st fastener 1a is provided with the latching mechanism for latching in the state by which the bending part 12 was bent with respect to the base 11. As shown in FIG. This locking mechanism includes a locking portion provided in the bent portion 12 and a locked portion provided in the base portion 11.

The locking portion is configured as a tongue piece 122 formed narrower in the bent portion 12 than the portion adjacent to the locking portion (the bent portion main body 121). On the other hand, the locked portion is raised from an end edge (the other side edge 111b) facing the end edge (one side end edge 111a) where the bent portion 12 is formed in the base body 111. It is configured as a hole (through hole 112a in this embodiment) formed in the raising piece 112 and into which the tongue piece 122 is inserted. When the bent portion 12 is bent, the locking portion (tongue piece 122) is locked to the locked portion (through hole 112a) in the base portion 11 so as to maintain the folded state.

The locking rising piece 112 of this embodiment is raised from the other side edge 111b in FIG. 1A of the base body 111 upward in FIG. 1B, that is, in the same direction as the bent portion 12. Similar to the bent portion 12, the base main body 111 and the latching rising piece 112 intersect at a right angle. The rising height of the locking rising piece 112 from the base body 111 is not particularly limited, and is a height that can ensure the strength of the locking rising piece 112 in a state where the tongue piece 122 is locked to the through hole 112a. I just need it.

The through-hole 112a which is a to-be-latched part is a horizontally long rectangular hole which penetrates the latching rising piece 112 as shown in FIG. 1C. The lower end of FIG. 1C coincides with the upper surface of the base body 111 in the through-hole 112a, and the horizontal dimension in the figure is larger than the width dimension of the tongue piece 122 and the width dimension of the bent body 121. Is also small. The vertical dimension in the figure is a dimension that exceeds the thickness dimension of the tongue piece 122. Preferably, when the tongue piece 122 is inserted as shown in FIG. 4B, the tongue piece 122 can enter from obliquely above. Dimensions.

The deformation of the bent portion 12 when the locking portion (tongue piece 122) is attached to the locked portion (through hole 112a) will be described with reference to FIGS. 4A and 4B. Although illustration of the band 2 is omitted in FIG. 4, in actuality, the band 2 in a state where the protrusion 13 penetrates the through hole 21 is sandwiched between the base portion 11 and the bent portion 12 that is bent. .

First, the operator pushes the bent portion 12 (particularly, the inflection portion 123) indicated by a broken line in FIG. 4A diagonally downward in FIG. 4A. Then, the bent portion 12 is deformed so as to rotate with respect to the base portion 11, and as shown by a solid line in FIG. 4A, the angle between the base portion main body 111 and the base end portion of the bent portion 12 is narrowed from a right angle to an acute angle. At this time, the inflection part 123 has not been deformed yet. Then, the tip edge of the tongue piece 122 abuts on the base 11.

Furthermore, when the operator pushes the inflection part 123, the inflection angle of the inflection part 123 is widened. Accordingly, the tip edge of the tongue piece 122 moves to the right in the figure. Thereafter, the tongue piece 122 is inserted into the through-hole 112 a of the locking upright piece 112. This movement of the tongue piece 122 is performed until the leading edge of the bent portion main body 121 abuts on the latching rising piece 112. As shown in FIG. 4B, the inflection part 123 is deformed to a substantially horizontal state. In this state, the locked state of the bent portion 12 to the through hole 112a is maintained.

Thus, according to the configuration in which the tongue piece 122 and the through hole 112a are combined, it is possible to easily attach the locking portion to the locked portion, and it is advantageous because the locking is ensured. In addition, since the operator only has to press the bent portion 12, it is possible to work with one hand, and both hands are not blocked, so that it is relatively safe. Further, since the operator can work by pressing the inflection part 123 with the thumb, no tool is required.

In addition, the structure using the lock | rock riser piece 112 in which the through-hole 112a was formed is not essential in this invention, The various structure which can lock the base 11 and a bending part is employable. For example, a hook-shaped portion is provided as a locking portion at the tip of the bent portion, and the hook-shaped portion is hooked on the edge of the base 11 as the locked portion so as to be locked. Can be configured. Moreover, as a to-be-latched part, the dovetail groove | channel formed by press work etc. other than the through-hole 112a of this embodiment can also be used. Further, the locking portion is not limited to the one provided in the bent portion 12 itself (tongue piece 122) as in the present embodiment, and a member different from the bent portion 12 connected to the bent portion 12 may be provided. . Further, the locked portion is not limited to a member (through hole 112a) provided in a member (locking rising piece 112) different from the base portion 11 connected to the base portion 11 as in the present embodiment. 11 itself can also be provided.

-Second fastener-
Next, the second fastener 1b will be described. Regarding the second fastener 1b, only a portion added to the first fastener 1a and a portion different from the first fastener 1a will be described. 2A to 2D, parts having the same functions as those of the first fastener 1a are denoted by the same reference numerals.

The second fastener 1b is mainly used when a supported object (pipe) P is attached to a structure using a bolt as shown in FIGS. 8A, 8B, and 9. As shown in FIGS. 2A to 2D, a bolt mounting portion 15 raised in the same direction as the bent portion 12 is provided at an end edge 111d of the base portion 11 in the direction intersecting with the longitudinal direction of the band 2 at the time of mounting. . The bolt mounting portion 15 has a bolt through hole 151 as shown in FIGS. 2A and 2C. By passing the bolt B through the bolt through hole 151, the supported object (pipe) P can be suspended from the ceiling C as shown in FIGS. 8A and 8B. Further, as shown in FIG. 9, a supported object (pipe) P can be attached to a support member X composed of a channel material, an angle material or the like.

Further, as shown in FIGS. 2A, 2B, and 2D, the bolt mounting portion 15 is formed with a rotation preventing projection 152 in the direction of the base portion 11. The anti-rotation protrusion 152 of the present embodiment is formed by being cut and raised from a planar portion in the bolt mounting portion 15. The anti-rotation protrusion 152 serves as a detent that suppresses the rotation of the hexagon nut N by contacting the side surface of the hexagon nut N attached to the bolt B that is passed through the bolt through hole 151. The rotation preventing projection 152 can prevent the hexagon nut N from being loosened and removed from the bolt B due to the influence of vibration or the like, and the supported object P falling together with the band 2 and the fastener 1 can be suppressed. In addition, it is desirable that the anti-rotation protrusion 152 is provided on the lower surface of the bolt attachment portion 15 at the time of attachment. This is because the hexagon nut N and the non-rotating protrusion 152 always come into contact with each other due to the suspended load of the supported object P, so that the anti-rotation can be reliably prevented.

The bolt mounting portion 15 of the present embodiment is composed of a set of two sheets facing each other at an interval slightly larger than the distance between the hexagon nuts N screwed into the bolts B mounted in the bolt through holes 151. . However, it may be formed so that the hexagon nut N is prevented from rotating by contacting the surface or corner of the hexagon nut N. For example, it can be formed only at one location. Moreover, when the nut screwed into the volt | bolt B is other than the hexagon nut N, it can be made into the shape which matched the rotation prevention protrusion with the shape of the said nut.

In the second fastener 1b, one of the protrusions 13 is raised not from the end edge of the base 11 but from a position near the center. Moreover, the bending part 12 in the 2nd fastener 1b of this embodiment is formed more narrowly than the bending part main body 121, as the width dimension of the base end part 124 is shown to FIG. 2B. By narrowing the base end portion 124 in this way, the bent portion 12 can be bent with a smaller force than when the base end portion has the same width as the bent portion main body 121. In addition, two elongated holes 125 are formed in the bent portion main body 121. The inflection part 123 is easily deformed by the long hole 125.

The construction example shown in FIG. 7A uses two first fasteners 1a. Like the construction example shown in FIG. 6A, one of the two is used for binding the band 2 and the other is a hook. The supported object (pipe) P is fixed to the wall W by allowing S to pass therethrough. The construction example shown in FIG. 7B uses one first fastener 1a, and, like the construction example shown in FIG. 6B, this first fastener 1a is fixed to the ceiling C with a ridge S. The supported object (pipe) P is fixed to the ceiling C.

The construction example shown in FIG. 8A uses the first fastener 1a and the second fastener 1b one by one. The first fastener 1a is used for binding the band 2 and the second fastener 1b is used. Bolts (full screw bolts) extending from the ceiling C are penetrated and fastened with nuts (hexagonal nuts) N, whereby the supported object (piping) P is fixed to the ceiling C. The construction example shown in FIG. 8B uses one second fastener 1b, and a bolt (full screw bolt) B extending from the ceiling C is penetrated through the second fastener 1b to form a nut (hexagonal nut). ) The supported object (pipe) P is fixed to the ceiling C by being fastened with N.

The construction example shown in FIG. 9 uses two second fasteners 1b, and bolts (hexagonal bolts) B are passed through the second fasteners 1b and fastened with nuts (hexagonal nuts) N. Thus, the supported object (pipe) P is fixed to the support member X made of a channel material, an angle material, or the like.

Next, a construction method using the band 2 and the fastener 1 of the present embodiment will be described with reference to FIGS. 5A to 5C. First, the band 2 is wound around the support P such as piping. Then, as shown in FIG. 5A, the base 11 of the fastener 1 is opposed to the portion where the band 2 (

portions

2x and 2y shown in FIG. 6A) overlaps after being wound. Then, the protrusion 13 is passed through the through hole 21 of the band 2.

Thus, the 1st fastener 1a can be fixed to the ceiling C, the wall W, etc. by hitting the heel S. Here, when only the band 2 is beaten, the head of the heel S may pass through the band 2 because the thickness of the band 2 is small, and the heel S may come out of the band 2 in some cases. On the other hand, when the first fastener 1a is hammered, the thickness of the first fastener 1a is large, so that the possibility that the heel S will come off can be reduced. Further, since it is not necessary to increase the thickness of the band 2 so that the heel S does not come out, the band 2 does not become difficult to wind around the supported object P.

In addition, the protrusion 13 and the latching rising piece 112 can be used as a misalignment guide for preventing the nailing machine from deviating. Moreover, when using the 2nd fastener 1b, as shown to FIG. 8A, FIG. 8B, and FIG. 9, the bolt B can be attached to the bolt attachment part 15, and the 2nd fastener 1b can be fixed. The bolt B shown in FIGS. 8A and 8B is a full screw bolt having no head and having a thread formed over the entire length. In this way, when using the full screw bolt, after the hexagonal nut N is screwed into the bolt B with the second fastener 1b with the supported object P attached via the band 2 once shifted upward. Then, the second fastener 1b is returned downward so that the hexagon nut 1 comes into contact with the anti-rotation protrusion 152.
