BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for suspending a folded material used for a roof material or the like.

[0002]

2. Description of the Related Art Folded materials are sometimes used as roof materials for buildings, etc., and when they are manufactured, transported, lifted during roof erection or replacement work, etc., they are gripped and lifted and moved to a desired location. There is a need to.

As shown in FIG. 12, for example, the folded material 1 is formed of a formed metal plate, and a pair of rising pieces serving as peaks is formed on both left and right sides with a valley in the middle. It is a long one in which the folded portion 2 is formed by further bending the tip.

In order to move the folded material 1 having such a shape, conventionally, as shown in FIG. 12, for example, as shown in FIG. 12, a plurality of folded materials 1 are stacked, and a bundled member 20 such as a nylon sling is formed as one bundle. The folded material 1 is wound around and bundled in the width direction, the hanging portion 20a at the end of the nylon sling is protruded upward, and a hook of a lifting machine such as a crane is hooked on the hanging portion 20a to be lifted and moved. doing.

[0005] In this case, since the folded material 1 has an open cross-section having an inverted chevron shape as a whole, when the right and left rising pieces are pushed from the outside to the valley side, they are easily crushed and deformed by an externally applied force. It's easy to do. For this reason, for example, the spacing member 22 using a pipe or the like is inserted inside the folded material 1 in the width direction like a holding rod to prevent deformation.

[0006]

Each time the folded material 1 is lifted, a spacing material is provided on the middle side to prevent deformation.
It is necessary to manually insert the 22 and not only takes time to fix it, but also a binding member with nylon sling etc.
In order to attach 20, the manual work of hand-drawing is required, the workability is not good, and labor and time are required.

When the folded material 1 is lifted while being inclined in the length direction, a binding member such as a nylon sling is used.
Since 20 is simply wound around the folded material 1, the folded material 1 may slip off from the binding member 20, and in order to prevent this, it is necessary to hold down the end of the folded material 1. It is necessary to separately provide members.

Further, if the binding member 20 made of nylon sling or the like protrudes outward from the side of the folded material 1, if a plurality of folded materials 1 are laid in parallel as a roof material or the like, a The next folded material 1 is arranged next to the folded material 1
When trying to lay the folded material 1, it may hit the folded material 1 already laid and interfere with this, and the next folded material 1 may not be laid smoothly, and the workability is not good.

An object of the present invention is to eliminate the inconveniences of the prior art, and when lifting a folded material, there is no need for a manual drawing operation using a binding member or the like or an operation for attaching a spacing material, thereby improving workability.

The object of the present invention is that the opposing gripping means arranged and attached to each arm are mutually connected by guide means.

Third, the gripping means is arranged such that a pair of gripping means is disposed on each of the folded portions on the left and right sides of the folded material, and the gripping means is connected on each side by guide means.

According to the first aspect of the present invention, if the folded portions formed at the ends of the rising pieces on both the left and right sides of the folded material are respectively gripped by the gripping means, the gripping means can be used to hold the folded portions by the arms. As a result, the gripping means is firmly fixed to the folded portions on the left and right sides of the folded material. This eliminates the need for cumbersome manual work for attaching the gripping means to the folded material, improves workability, and makes it easy to lift the folded material by lifting it with a lifting machine or the like via the hanging piece attached to the arm. Yes, there is no danger of falling on the way,
It is safe.

Further, the gripping means is constituted by a mechanism such as a clamp which grips the folded portion of the folded material from the inside in the vertical direction and has no portion protruding outward from the folded portion, so that the folded material already laid is provided. For example, when laying the next folded material in parallel, such as when laying in parallel, since the gripping means gripping the folded material does not have a portion protruding outward, just lower the suspended folded material as it is, Easy to lay.

The arms are formed of bar-shaped members, and the two are rotatably connected in a cross shape, and the ends of the arms are urged between the arms in the direction of the folded portions on both the left and right sides of the folded material. A spring is provided, and a gripping means is attached to the tip of each arm. Therefore, the tip of the arm is pressed in the direction of the folded portions on the left and right sides of the folded material by the elasticity of the spring. Therefore,

[0021]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a perspective view showing a first embodiment of a folded material suspending device according to the present invention. The suspended device 3 has, as a basic configuration, a folded portion formed at the end of a rising piece on both the left and right sides of the folded material 1. A gripping means 4 for gripping each of the grippers 2, an arm 5 to which the gripping means 4 is attached at the tip and pressing it in the direction of the folded portion 2, and a hanging piece 12 attached to the gripping means 4 or the arm 5. Main components.

In the first embodiment, the arm 5 has a predetermined length of 2 mm.
The two bar-shaped members 6a and 6b are crossed at the center and overlapped, and the overlapping portion is rotatably mounted on a pin 7 so as to be rotatable. Shaped member 6
A tension spring 8 for urging the bar-shaped members 6a, 6b in such a direction as to open outward is inserted between the bar-shaped members 6a, 6b.

A gripping means 4 by a clamp 9 is rotatably attached to the tip of each of the bar-shaped members 6a and 6b via a mounting hardware 10. In the example shown in FIG. 1, the clamp 9 has a U-shaped main body 9a attached to a mounting hardware 10 with its opening facing outward, and a screw 9c projects from the upper part of the main body 9a into the main body 9a. A plate-shaped pressing piece 9b was attached to the tip of the screw 9c.

As described above, a pair of clamps 9 are disposed on the left and right sides of the overlapped portion of the bar-shaped members 6a and 6b, which are the arms 5, respectively. Guide rods 11 serving as guide means are slidably mounted on the left and right sides between the mounting hardware 10 to be attached to the members 6a and 6b, and the clamps 9 on the left and right sides are mounted.
Are arranged in a straight line with each other.

In the first embodiment, the hanging pieces 12 are provided above the overlapping portions of the bar-shaped members 6a and 6b.

Next, a method of lifting the folded material 1 by the lifting device 3 will be described. Although the shape of the folded material 1 is as described above, the folded portion 2 includes a rising portion 2a that rises vertically in the illustrated example, a horizontal portion 2b that is horizontally bent inward from the rising portion 2a, The horizontal portion 2b is further formed with a bent portion 2c in which the tip is bent obliquely downward inward.

The suspending device 3 is set inside such a folded material 1. At this time, the two bar-shaped members 6a and 6b are pushed open so that they are folded flat against the elasticity of the tension spring 8, and the interval between the right and left opposed clamps 9 is reduced, so that the suspension device is provided. 3 is arranged inside the folded material 1.

Then, the right and left clamps 9 are applied to the inside of the folded portion 2 of the folded plate material 1 respectively, and the tension springs 8
When each clamp 9 is pressed against the folded portion 2 by the elasticity of the clamp 9, the horizontal portion 2b and the bent portion 2c of the folded portion 2 enter into the opening of the main body 9a of the clamp 9, and the pressing piece 9b is positioned above the horizontal portion 2b. I do. At this time, the clamps 9 located on the left and right sides are connected by the guide rods 11 on each side, so that the clamps 9 can be set in the folded portions 2 on the left and right sides almost simultaneously without being separated.

When the screw 9c is pushed in this state, the pressing piece 9b presses the horizontal portion 2b, the horizontal portion 2b and the bent portion 2c are sandwiched between the pressing piece 9b and the main body 9a from above and below, and the folded portion 2 is It is fixed to the clamp 9.

Thus, the hook 1 of a lifting machine such as a crane is hooked on the hanging piece 12 to lift the folded material 1. In the suspended state, the folded material 1 is fixed to the right and left by two clamps 2 at each of two places, so that a stable state can be maintained without tilting.

Then, for example, when it is moved to a predetermined laying position such as a roof frame, it is lowered here. At this time,
Since the clamp 9 grips the folded material 1 from the inside, the members of the clamp 9 do not protrude outside the folded material 1, and when the folded material 1 is juxtaposed, the juxtaposed position is set. Even if it is lowered as it is, there are no obstructive objects and good workability of laying work can be achieved.

FIGS. 2 to 4 show a second embodiment of the first embodiment. The basic structure is the same as that of the first embodiment, but the end of the clamp 9 is rotatably pivoted. The upper clamp 9d is formed by upper and lower clamping pieces composed of an upper clamp 9d and a lower clamp 9e, and the upper clamp 9d is provided with a lever 9f for pressing the lower clamp 9e.
A crimping projection 9g made of an elastic member such as rubber is provided on the lower clamp 9e at the tip.

On the other hand, as shown in FIG. 4, the lower clamp 9e is provided with a pressing projection 9h on the folded portion 2 side of the folded material 1 at an upper portion thereof. In the drawing, reference numeral 9i denotes a compression spring biased so as to press the pressing protrusion 9h toward the folded portion 2.
At the tip of the lower clamp 9e, there is provided a locking projection 9j which is rotated upward by the torsion force of the torsion spring 9k and inserted into the inside of the folded portion 2.

In this embodiment, the guide rod 11 is mounted on the upper clamp 9d.

The basic operation for attaching the suspension device 3 of the second example to the folded material 1 is the same as that of the first example, but as shown in FIGS. Then, the upper clamp 9d is pivotally moved upward with its tip centered on the shaft attachment portion, and is opened between the upper clamp 9d and the tip of the lower clamp 9e.

In this state, the locking projection 9j at the tip of the lower clamp 9e is inserted into a gap surrounded by the horizontal portion 2b, the bent portion 2c and the rising portion 2a of the folded portion 2 of the folded plate 1 and pressed. When the tip of the projection 9h contacts the outside of the bent portion 2c, the clamp 9 is pressed in the direction of the folded portion 2 by the pulling force of the tension spring 8, and the locking protrusion 9j is moved upward by the torsion force of the torsion spring 9k. It turns and rises in the gap, and its tip presses against the lower surface of the horizontal portion 2b.

On the other hand, the tip of the pressing projection 9h has a compression spring 9i.
Is pressed to the tip of the bent portion 2c by the elasticity. When the lever 9f provided on the upper clamp 9d is further pushed up from this state, the press-contact protruding portion 9g at the tip rotates downward and press-contacts the upper surface of the horizontal portion 2b. As a result, the folded portion 2 of the plate material 1 has a horizontal portion 2b having a crimping protrusion 9g and a locking protrusion 9j.
As a result, the bent portion 2c is pressed from the inside by the pressing protrusion 9h, and is fixed from above and below by the upper clamp 9d and the lower clamp 9e.

Accordingly, if the hook of a lifting machine such as a crane is hooked on the hanging piece 12 and the folded material 1 is lifted,
Also in the case of the second example, since the folded material 1 is fixed to the right and left at two places each by two clamps 9, a stable state can be maintained without inclining.

Since the clamp 9 does not protrude outward from the folded portion 2 of the folded material 1, when the clamp 9 is arranged side by side with the folded material 1 already laid in the same manner as in the first example, the clamp 9 remains at the juxtaposed position. Even if it is lowered, there is no obstructive object, and the workability of the laying work can be improved.

FIG. 8 shows a third example of the first embodiment. As a structure of the clamp 9, a mechanism for pressing the folded material 1 against the folded portion 2 is a ratchet mechanism instead of the screw of the first example. , A support arm 9 erected from the upper part of a U-shaped main body 9a
m to rotatably support the middle of the lever 9n near its tip,
A pressing rod 9l attached to the lower end of the lever 9n is projected from the upper part of the main body 9a to the inside, and a pressing piece 9b is attached to the lower end. Further, a tension spring 9o is provided between the vicinity of the base end of the lever 9n and the main body 9a. Installing.

Then, a ratchet gear 9p is installed on the upper part of the main body 9a, and a ratchet claw 9q meshing with the ratchet gear 9p is provided on the side of the lever 9n. 9r in the figure indicates a ratchet release button attached to the base end of the lever 9n.

In order to fix the clamp 9 by the ratchet mechanism to the folded portion 2 of the plate material 1, the ratchet release button 9r is operated to release the engagement between the ratchet gear 9p and the ratchet pawl 9q. With the elasticity of the extension spring 9o, the tip of the lever 9n is pulled up with the support point of the support arm 9m as a fulcrum, and the pressing piece 9b is moved to the main body 9
It is located above in a.

Accordingly, the folded portion 2 is inserted into the gap formed between the pressing piece 9b and the lower portion of the main body 9a, and the lever 9n is pulled against the elasticity of the tension spring 9o while the ratchet claw 9q is engaged with the ratchet gear 9p. And pull it up,
The tip of the lever 9n is pulled down with the support point of the support arm 9m as a fulcrum, and the pressing piece 9b is pressed against the upper part of the folded portion 2. As a result, the folded portion 2 is clamped between the pressing piece 9b and the lower portion of the main body 9a from above and below, and is fixed to the clamp 9.

The other operations are the same as those of the first and second examples, and the detailed description is omitted here.

The above-mentioned example is a case where the right and left folded portions 2 of the folded material 1 to which the clamps 9 are fixed are parallel as shown in FIG. 9 (a), but as shown in FIG. 9 (b). In the case where the folded portion 2 is not parallel and has, for example, a flat C-shape, the overlapping position of the two bar-shaped members 6a and 6b is shifted from the center to change the opening angle, so that the left and right clamps 9 are opposed to each other. The spacing can be different in the length direction of the folded material 1,
It is possible to cope with a case where the left and right folded portions 2 are not parallel.

In this case, the two bar members 6a, 6b
If a plurality of bonding holes for polymerization are formed in advance at the center of the plate, an arbitrary one can be selected to quickly deal with a folded material 1 in which the left and right folded portions 2 are not parallel.

In the first embodiment, the arm 5 is formed by crossing bar-shaped members 6a and 6b of a predetermined length. In the second embodiment, the arm 5 is connected to a jack 13a as shown in FIG. 10 as a first example. , 13b made of an elastic member,
The clamps 9 are arranged in parallel with each other, and the clamps 9 are rotatably attached to the ends of the jacks 13a and 13b, respectively, and the opposing members of the clamps 9 attached to the jacks 13a and 13b are mutually connected by the guide rod 11. Connected.

In this case, the hanging pieces 12 are attached to the clamps 9 at diagonal positions.

In order to fix the suspending device 3 to the folded material 1, the jacks 13 a and 13 b are contracted and set inside the folded material 1 with the distance between the clamps 9 attached to both ends thereof being reduced. Then, when the jacks 13a and 13b are extended, the clamp 9 at the tip grips the folded portion 2 in the same manner as in the first embodiment.

When the folded portion 2 of the folded material 1 is not parallel, the jacks 13a, 13
By making the extension lengths of b different, the clamps 9 respectively attached to the tips are arranged at the C-shaped positions.

FIG. 11 shows a second example of the second embodiment, in which one arm 5 is formed of an elastic member such as a jack 13 and the other arm 5 is formed of a bar-shaped member 6 of a predetermined length, and is folded right and left. These jacks are located between the opposing clamps 9, 9 for gripping the part 2.
13 and the bar-shaped member 6 are installed in parallel, and the clamp 9 is rotatably attached to the end of each of the jack 13 and the bar-shaped member 6. Opposing members of the jack 13 and the clamp 9 attached to the bar-shaped member 6 are rotatably connected to each other by a guide rod 11.

As a result, a parallel link is formed by the jack 13, the bar-shaped member 6, and the two guide rods 11. Therefore, when setting the suspension device 3 on the folded material 1, FIG. If the shape of the parallel link is flattened as shown by a chain line, the interval between the opposed clamps 9 can be reduced without contracting the jack 13. Then, after setting it in the middle of the folded material 1,
The clamp 9 can be fixed to the folded portion 2 by extending the jack 13 as necessary.

If the folded portion 2 of the folded material 1 is not parallel, the jack 13 is contracted or extended to make the length different from that of the bar-shaped member 6 as shown in FIG. The clamps 9 respectively attached to the horns can be arranged at the positions of the C-shape.
