Description

[Detailed description of the invention] The hanging device of the present invention is capable of suspending and transporting building columns, frame materials such as rice cakes, panels such as wall panels, floor panels, roof panels, and other building components using a crane. It is used when constructing a building, and the workability of this work,
The purpose is to improve safety.

Conventionally, when suspending a construction component, the construction component C is suspended from the wire rope 1 of the crane body A via an intervening device B, as shown in Fig. 10. When the wind blows, the building components C swing, rotate, or turn under the pressure of the wind, making it difficult to move the construction components C to a predetermined position. It may collide with structures, electric wires, adjacent structures, etc., damaging these objects or damaging the building component C itself.

At the same time, construction site work is exposed to danger due to the heavy construction components C swinging, rotating, and turning, which poses a safety problem at the construction site.

In addition, when the wind is particularly strong, the above conditions exceed the limits, making it impossible to work, and it is necessary to suspend or stop the work until the wind subsides, which also has the disadvantage of reducing work efficiency. be.

The suspension device of the present invention eliminates the above-mentioned conventional drawbacks, and allows construction materials C to be lifted from the crane body A via an intervening tool B.
In this hanging device, a pair of upper and lower core members D are formed so that the legs can be fixed freely from a substantially parallel state to a V-shaped state, and two blades F with a sheet material E stretched between them. An air resistance body G, which is arranged oppositely on the left and right, and is formed by forming two left and right blades F, F so that the legs can be fixed freely in a substantially parallel state to an angular shape, is attached to an interposer B or a building member C. It is characterized by being provided on one side of the.

Hereinafter, the present invention will be explained in detail based on the drawings.

1 and 2 show an embodiment of the present invention, in which an air resistance element G is provided on one side of a building member C made of a panel.

The air resistance element G is made of iron or plastic whose base part is supported by a pin on a substantially groove-shaped base body 4 provided with a clamping body 3 that can be expanded or contracted by screws 2, 2, and whose legs can be freely opened from a substantially parallel state to a V-shaped state. A pair of upper and lower core materials consisting of D, etc., and a sheet material E consisting of cloth, synthetic resin (e.g. polyvinyl chloride), aluminum foil, etc.
Two blades F, which are stretched with The blades F, F are fixed in the spread state using a fixture 5.

The fixture 5 has horizontal shafts 8, 8 which can be extended and fixed between vertical shafts 7, 7, each having a bent part 6 above and below which is fitted into the free end of the core material.

Fits into the free end of D to securely hold the blades F and F in an expanded state.

Note that the air resistance element G can be assembled by removing the fixture 5 and attaching the blade F,
It is convenient because the blades F can be compressed inwardly in the horizontal direction, and each blade F can be compressed inwardly in the vertical direction, making it possible to transport, store, etc. in a compact state.

Furthermore, when the hanging device according to the embodiment of the present invention is used, when the wind blows, wind pressure acts on the air resistance element G, and the attitude of the building member C is changed so that the side on which the air resistance element G is installed is on the leeward side. Since the wind pressure is constant along the flow direction, the wind pressure applied to the building member C is reduced, and the building member C does not move, rotate or turn, and therefore,
Workability and safety are improved, and the structure of the already erected building, electric wires, adjacent structures, or the building component C itself is not damaged.

In addition, in this embodiment, depending on the strength of the wind, the blades F,
It is convenient because the angle of F can be adjusted, and since the air resistance element G can be detachably attached to the building member C using the clamping body 3, it goes without saying that the air resistance element G can be used repeatedly. be.

3 to 5 show different embodiments of the present invention, in which an air resistance element G is provided on one side of the interposer B.

The interposer B of this embodiment includes the wire rope 9 of the crane main body A, the horizontal rod 10, a pair of auxiliary ropes 11 and 11 for supporting the horizontal rod 10 on the wire rope 9, and the locking of the lower surface of the horizontal rod 10. It hangs from the receiving part 12.12 and hangs from the hanging ropes 13, 13 that hold the building component C,
An air resistance element G consisting of vanes F and F is provided at one end of the horizontal rod 10.

In the figure, 14 is a balancer for keeping the weight and balance of the air resistance body G.

The configuration of the air resistance body G of this embodiment is approximately the same as the configuration of the air resistance body G of the other embodiment described above, and a pair of upper and lower legs are formed at one end of the horizontal rod 10 so that they can be opened vertically. A pair of blades F, F with a sheet material E stretched between the core material and D, is formed so that the legs can be opened freely by supporting a pair of bases on the left and right with pins,
A fixture 5 is used to hold the blades F, F in an expanded state.

FIG. 4 shows a state in which the fixture 5 is removed and the blades F, F are retracted, which is extremely easy to handle when transported and stored together with the horizontal rod 10.

6 to 9 show still another embodiment of the present invention, in which a blade F is provided with a sheet material E stretched between a core material and D on one side of a horizontal rod 10 in an intervening tool B; An air resistance body G is provided in which F is formed so that its legs can be freely spread and fixed to the left and right.

The core material is made of a flexible material such as iron or FRP, and is fitted into the pipe body 16 slidably on the horizontal rod 10 and fixed with screws 15, and four core materials are attached to the pipe body 16. D, D, D
The base of is rotatably mounted.

Reference numeral 17 denotes a support arm, one end of which is rotatably attached to the middle of the core member, and the other end rotatably attached to the distal end of the horizontal rod 10.

The mounting piece 18 that rotatably supports the support arm 17 is formed obliquely horizontally outward at a certain angle with respect to the axial direction of the horizontal rod 10, and the support arm 17 itself has a mounting portion to the mounting piece 18. It is bent outward at a certain angle in the vicinity.

In this embodiment, as shown in FIG.
7 stands up and has a pair of upper and lower core members, D opens its legs up and down and the blades F open, the mounting pieces 18 are formed diagonally outward, and the support arms 17 are bent. As a result, the pair of blades F and F also open to the left and right, forming an air resistance element G.

Also, as shown in FIG. 9, when the tube body 16 is slid toward the center of the horizontal rod 10, the support arms 17 and 17 lie down, and the pair of upper and lower core members, D, closes, and each core member, D, D,
D converges to a state along the horizontal rod 10.

In addition, in FIGS. 8 and 9, illustration of the sheet material E is omitted for the sake of explanation.

If the length of the support arm 17 and the length from the part where the support arm 17 of the core material is attached to the free end are made the same, as shown in Fig. 9, when the core material of the blade F is converged, Since the end of the core material does not protrude from the end of the horizontal rod 10, handling during transportation and storage is improved.

In each of the above-mentioned embodiments of the present invention, the case where the building member C is a panel is exemplified, but the present invention is not limited to this in any way, and the building member C may be a column, a beam, etc. Of course it's a good thing.

As mentioned above, the hanging device of the present invention is a hanging device in which building members are hung from the side of a crane via an intervening device, and the legs can be fixed freely from a substantially parallel state to a ＼-shaped state. Two blades with sheet material stretched between the pair of upper and lower core materials formed are placed opposite each other on the left and right sides.The two blades on the left and right sides are formed so that they can be fixed freely from a substantially parallel state to a V-shaped state. The air resistance element is provided on one side of the intervening tool or building member, so when using the air resistance element, each core material can be expanded to spread the blades. When transporting and storing, each core material can be gathered together and the blades can be folded into a compact form for handling, which makes handling extremely convenient, and the blades are less likely to be damaged.

In addition, when the wind blows, wind pressure acts on the air resistance element, and the posture of the building component remains constant along the direction of the wind flow, with the side where the air resistance element is installed facing downwind, reducing the wind pressure that the building component receives. Also, the building components do not swing, rotate or pivot,
It improves the workability of transporting building parts and building and assembling work, and improves the safety of work at the building site, and also improves the workability of building parts, the structure of the already erected building, the adjacent structures, or the building parts. It cannot be damaged itself.

Further, even if strong winds blow, there is no need to interrupt or stop the work, so work efficiency is improved in that sense as well.

In addition, since the air resistance element is used with two blades spread apart in a V-shape, the outer surfaces of the two blades can receive wind resistance even in a light breeze, and the posture of the building component is always maintained. can be kept constant along the wind flow direction.
