Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus used for the construction work of building materials such as panels and studs of steel-framed reinforced concrete buildings, and particularly when building middle-rise and low-rise buildings,
The present invention relates to a working device that can be folded and carried, and can be easily moved and installed even in a narrow space or an outer wall portion near a pillar.

[0002]

2. Description of the Related Art Conventionally, in order to improve the efficiency of large-scale work when constructing a high-rise building, a work device of this type has a portable switch panel at hand, which extends forward and backward on a trolley traveling forward, backward, leftward and rightward. There have been proposed various types of working devices called robots in which an arm moves up and down, and a material gripping means whose angle can be adjusted vertically and horizontally is provided on the tip side of the arm.

[0003]

However, the conventional robot working apparatus as described above is heavy and bulky and cannot be lifted when building a low-rise narrow building without a large work lift. Is. Furthermore, even if the robot arm itself is expandable and contractible, it does not rotate and bend in the horizontal direction, so it is difficult to construct an outer wall panel approaching a pillar through a narrow gap between the inner working floor and the next house. This was accompanied by an inevitable result of relying on the heavy labor of skilled workers.

The present invention has been made in view of the problems of the prior art, and is easily disassembled by removing the members of the apparatus to form columns (posts) between the upper floor and the beams. A horizontal arm composed of a plurality of parts that are fixed by crimping and pivotally attached to a column can be manually pivoted and folded freely within a 360 ° range, and the arm can be placed at any position whose radius is the entire length of the arm. The material is designed not to be moved and arranged, and is intended to be installed while moving around even in a narrow position on the back side of an obstacle such as a pillar or a material stack.

[0005]

In order to achieve the above-mentioned object, a working apparatus for construction according to the present invention has a jack having a pedestal arranged on the floor at the lower end of a post made of a circular tube, and the upper end of the post. A height adjuster equipped with a crimping and locking part whose upper end is fixed to a beam or the like is provided on the part. A rotatable sleeve shaft is provided at a desired height position of the post, and a first arm is horizontally fixed to the sleeve shaft. A bearing piece is projectingly provided at the tip of the first arm, and a support shaft provided by the projecting piece of the shaft rod is axially inserted into the bearing piece. At a position diametrically opposed to the support shaft position of the shaft rod, a projecting piece is projected to raise the support shaft, and the support shaft has a second
The bearing piece protruding from the base end of the arm is interposed. A bearing piece provided at the tip of the second arm is provided with a protrusion with a support shaft provided at the base end of the third arm, and three arms are provided so as to be pivotable and turnable.

A winch is suspended from the tip of the third arm by a rope, and several kinds of gripping means for gripping a material such as a floor plate are selectively provided at the lower end of the wire rope of the winch. Then, the cord pulled out from the winch is adjusted by moving it up and down so as to fit the material by grasping the material with a portable switch board provided at the base end through a hanging metal fitting provided on the arm.

[0007]

[Operation] The post is temporarily erected at the floor position directly below the beam within the range to be constructed, and the adjuster screwed on the upper end of the post is rotated and raised, and the locking part at the upper end of the adjuster is brought into contact with the lower surface of the beam. . Then, the jack at the lower end of the post is rotated to crimp and lock the locking portion to the beam member.

The first arm base end is bolted to a bracket provided on the sleeve shaft of the upright post. A support shaft provided on a shaft rod is inserted into the bearing piece at the tip of the first arm from the upper side, and is pivotally attached over an angle range of 180 °.
The bearing piece provided at the base end of the second arm is inserted into the support shaft provided at the position opposite to the bearing piece of the shaft rod from the upper side, and 180
It is pivotally pivoted over an angle range of °. When the floor area of the building to be constructed is small or the panel is laid within the narrow floor area to make the work easier, it is sufficient to install up to the second arm. This is because the first arm can be pivotally arranged in all directions by the sleeve shaft, and the second arm can be rotated until it overlaps with both side surfaces of the first arm because the rod is interposed. This is because it can be folded and the material can be moved and disposed at any position within the first and second length ranges.

When a bearing piece is provided at the tip of the second arm and a support shaft of the base end of the third arm is inserted and pivotally attached to the bearing piece from above, the third arm is perpendicular to both sides of the second arm. Rotate to the direction. When the second and third arms are lightly pushed by hand, the material can be moved to a desired position while easily turning with respect to the post.

A winch suspended from the arm tip by a rope is provided, and a gripping means is provided at the lower end of the wire rope of the winch. When the material is grasped by the grasping means, the material is lifted to a desired height and moved while being operated by a winch switch.

There are several kinds of gripping means for the material. In the case of the floor panel, one or two gripping means are used to move horizontally to the disposing position while holding horizontally, and in the case of the wall panel, the longitudinal direction. It facilitates installation work by gripping one end and moving it while suspending.
