DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transport device for transporting building members in a high-rise building or the like horizontally and vertically, and more particularly, to constructing the top floor of a building in advance and lowering the top floor from below. In a construction method for constructing a lower part of the top floor while sequentially ascending upward, the present invention relates to a transfer device for automatically transferring building members horizontally and vertically as the top floor is raised.

[0002]

2. Description of the Related Art When constructing a high-rise building, the top floor of the building is constructed in advance, and the top floor is raised by a jack-up device using support columns supporting the top floor as guides, and the lower part of the top floor is raised. There is a construction method for a high-rise building in which a work space for constructing a lower floor is formed, and building materials are supplied from the above-ground portion to sequentially construct higher floors.

In the construction method described above, a lifting device for transporting building members for constructing a lower floor in a lower working space on the uppermost floor has a temporary lifting lift at a construction site, and particularly transports a long object. There is an existing lift called a long lift, which lifts and lowers a rectangular carrier between two guide rails. A hoist is installed on the ground and the carrier is mounted on the hoist. The lifting wire is wound and the loading platform is raised and lowered to a predetermined height.

In addition, in the above construction method, an overhead traveling crane is installed at the lower part of the top floor, and an electric hoist is attached to an electric trolley on the overhead traveling crane. The material is lifted from outside by a hoist, and the overhead traveling crane travels horizontally to be transported to a predetermined mounting position, and is transferred and transported to another mounting device.

[0005]

As described above, a work space in which a top floor is raised to form a lower floor below the top floor is formed, and the work space is used to supply building members from the ground. However, the conventional transport device described above has the following problems. The unloading lift is for unloading long reinforcing bars and timber on a rectangular loading platform, and the loading is performed by an operator or using a forklift, which requires a lot of labor and a lot of loading time. I need it.

In addition, since the installation place and the lift structure are simple, it is not suitable for loading and transporting a large heavy object, for example, a steel frame column or a girder (including a precast concrete member) used for a frame. . As for the overhead traveling crane, as the height rises with the rise of the top floor, the wire wound on the electric hoist mounted on the electric trolley of the overhead traveling crane is unwound to lift the overhead traveling crane. In order to cope with this, the hoisting machine must be wound with the wire of the final lift, so the winding cylinder for storing the wire becomes large, and the hoisting machine itself becomes considerable weight,
As a result, the electric trolley and overhead traveling crane equipment are heavy and there is a limit to the unloading of the weight of the load, and there is no guide member for the load, so the lifting position to be lifted is unstable, and other transport equipment This makes connection with the camera complicated, and is not suitable for automatic conveyance by automatic control.

The present invention has been proposed in view of the above-mentioned problems of the prior art, and has an object to raise the top floor of a building in advance and construct a lower floor below the top floor. In a transport device that forms building work space and supplies building members from the ground part, the loading time of heavy building members is reduced by interlocking the horizontal transport device and the vertical transport device,
By performing horizontal and vertical conveyance fully automatically,
Another object of the present invention is to provide a horizontal and vertical transport device for transporting building members safely.

[0008]

In order to achieve the above object, a horizontal / vertical transport device according to the present invention raises the top floor of a building to be built in advance and places a lower floor below the top floor. In a horizontal and vertical transport device that forms a work space for constructing and supplies building members from the ground part to the work space, a cargo handling area provided on the ground part, and a horizontal transport means for receiving and transporting the building material from the cargo handling area Vertical transfer means for receiving a building member from the horizontal transfer means and transferring the building member to the work space; first transfer means for transferring the building member from the cargo handling area to the horizontal transfer means; and the horizontal transfer means. And a second transfer means for transferring the building member to the vertical transfer means, and the second transfer means is located in a range connecting the horizontal transfer means and the vertical transfer means. Hanging on the second gate crane and the second gate crane It was constructed by an automatic gripping device.

The horizontal conveying means b is for mounting a building member K over the two-chain chain conveyor arranged in parallel at a fixed interval, and is, for example, a steel column built on one level. The both ends of the column are placed on each chain 14 so that the beam-type bracket of the column does not interfere with the chain conveyor. The building member K is conveyed by the truck e, lifted by the first portal crane a ', and placed on the two-chain conveyor. At this time, the attachment 15 provided on the chain conveyor is stopped at the initial predetermined position, and the lifted building member K is placed at a position where it is hooked on the attachment 15.

Since the attachment 15 is provided at regular intervals in the feed of the chain, a distance measuring device provided on the motor with a speed reducer measures the distance each time the attachment 15 is operated, and the chain is advanced at intervals of attachment. On the other hand, when the building member reaches the tip of the chain conveyor, the chain conveyor operates if the building member is not removed by the interlock at the tip, and if the interlock is malfunctioning, the runaway detection limiter switch is activated do it,
The chain conveyor is configured to stop.
