Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is a rail in which a large number of arms are projected in a cantilever shape on the outside of a construction site constructed at a construction site, and the arms are bridged over the arms and supported around the construction site. The present invention relates to a building material transportation method in which a hoist is driven to travel and a building material is hoisted by the hoist and at the same time, the building material is transported to a required location.

[0002]

2. Description of the Related Art The inventor of the present invention has invented a device for hoisting a building material by a hoist that hangs wheels on a rail supported around a site structure in such a manner and drives the rail to travel like a monorail, and at the same time conveys the building material to a required place. , Actual Kaihei 4-72
994. This rail is continuous over the entire circumference of the building frame including the corner, eliminates wheel slippage at that corner, increases the radius of curvature at the corner so that the hoist can travel smoothly, and
The number of hoist wheels hooked on the rail is one.

In order to increase the radius of curvature of the rail whose axial center direction changes at the corner, it is necessary to lengthen the arm that supports the rail and project it largely outside the site structure. If the length of the arm is increased, the tip of the arm tends to bend, making it impossible to lift heavy building materials. Also, if the number of wheels supporting the hoist on the rail is small, heavy building materials cannot be lifted. As described above, the rail is largely curved at the corner, and in the conventional device in which the number of wheels supporting the hoist is small, the building material that can be lifted and transported is limited to a small and lightweight building material.

Therefore, the present inventor decided to separate the two linear rails 15 and 16 whose directions intersect at the corners 22 and 23 of the site structure 11 from each other while using a plurality of hoist wheels. In the corner 22, an auxiliary rail 42 supported by a horizontally rotating rotary arm 43 is provided between the linear rails 15 and 16, and the hoist 19 is transferred from the one linear rail 15 to the auxiliary rail 42. , Rotating the rotation arm 43 around the support column 35,
The auxiliary rail 42 and the hoist 19 are rotationally moved and connected to the other linear rail 16, and the hoist 1 which is rotationally moved is connected.
9, the auxiliary rail 40 is rotatably supported horizontally in the arm 41 provided between the linear rails 15 and 16 at the entry corner 23,
A switchable rail is devised in which the hoist 19 transferred from one linear rail 15 to the auxiliary rail 40 is rotationally moved together with the auxiliary rail 40 around the pin 54 and transferred to the other linear rail 16 to be connected. Japanese Patent Application No. 5-261
No. 02.

[0005]

However, in the switchable rail, an auxiliary worker who switches the direction of the auxiliary rails 40 and 42 is required, and the construction material 20 is attached to the rope 39 that moves up and down from the hoist 19. It is not possible for the lifting worker to carry out on-site material transfer work alone.

[0006]

SUMMARY OF THE INVENTION Therefore, according to the present invention, the rails at the corners are not made switchable, but the bow rails disclosed in Japanese Utility Model Laid-Open No. 4-72994 are used to reinforce the wheels of the hoist and to reinforce the rails to bear the weight of the hoist. (EN) A structure for improving rails for supporting rails so that a heavy rail can be easily arranged.

Connecting material 2
A sub plate 28 is attached to and screwed to the rail 7, and (4) the linear rails 15 and 16 and the corner rail 1 are inserted through the sub plate 28.
