Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a horizontal member holding device for a crane which is particularly effective in the construction of high-rise buildings.

Conventional technology Traditionally, when constructing a high-rise building, the work of lifting steel frame components such as columns, beams, and flooring upwards was generally done by installing a high-lift jib crane at a high location and lifting the steel frame components suspended by wires. It is suspended from a rope and transported to the desired installation location.

Problems to be Solved by the Invention The above-mentioned work is dangerous and requires specialized workers in important positions, and moreover, the work is difficult in times of strong winds or rain.

In view of the decrease in the number of specialized craftsmen, an object of the present invention is to provide a horizontal member holding device for a crane that allows work to be carried out safely, efficiently, and easily.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention has two sets of a plurality of holding struts suspended in the front and back from an elevating body that is movably suspended from a crane, and these two sets are suspended from each other. A spacing adjustment means for moving the holding columns closer to each other is provided, and supporting claws that can freely move in and out of the holding columns that face each other in the vertical direction at predetermined intervals in the vertical direction of each holding column and can support a horizontal member in a horizontal position are provided on the same plane. This is based on grain weight.

Effect In the above configuration, the elevating body is placed above the flooring materials stacked at regular intervals via railroad ties, etc.! Then, lower the elevating body, insert the holding column into the suspension notch formed on the outer edge or the suspension hole penetrated through the flooring material, and make the retracted support claw protrude below the flooring material. By raising the elevating body, the edge of the notch or the hanging hole can be locked by the support claw, the flooring can be held in a horizontal position in multiple stages, and it can be transported to the desired location. After placing the lowest floor material, the holding column can be pulled out from the notch or hanging hole by retracting the support claw and raising the lifting body, and it can be moved to the desired location sequentially starting from the lower floor material. It can be distributed and unloaded.

In addition, the spacing between the holding columns can be reduced using the spacing adjustment means.
Support on the same plane is achieved by lowering the holding columns from above to both sides of the horizontal beam materials stacked at regular intervals, and by raising the elevating body by protruding support claws below the beam materials. The claws can support one beam in a horizontal position and hold multiple beams. Then, the beam material can be lowered to the target location in order starting from the lowest one.

As shown in FIGS. 13 and 14, each of the holding columns 58A, 58B has openings 67 formed at four regular intervals on the front and rear opposing sides, and the holding columns 58A, 58B correspond to the openings 67. A support claw 57 is attached within 58B so as to be rotatable in the directions of arrows P and Q via a horizontal axis θ8 in the left-right direction. Then, a retraction cylinder 69, which is suspended for each support claw 57 from a bracket above the horizontal shaft 68 within the holding columns 58A, 58B, moves the support claw 57 to a retracted position and an opening facing upward via an operating lever 70. It is configured to be rotatable in the directions of arrows P and Q between a protruding position that protrudes from the portion 67 in the horizontal direction.

According to the above configuration, the overhead crane device 1 is operated, the lifting frame 55 is moved above the group of four stacked flooring materials via the sleepers G, and the lifting frame 55 is lowered by the winch device 51. Each retaining post 58A.

58B into the suspension hole E of the floor material, and when the lower end support claw 55 is lowered below the lowest floor material, all the egress/retraction cylinders 69 are contracted and the support claw 57 is moved back. The winch device 51 rotates in the direction of arrow P from 1 to the protruding position.
The elevating frame 55 is slightly lifted to lift the four floor coverings. At this time, the sleepers G may be removed, and the lifting frame 55 is lifted up and the ceiling crane 1 is operated to transport the flooring to the desired installation location. After making a decision.

First, the lowermost retractable cylinder 69 is extended to return the support claw 57 to the retracted position, the elevating frame 55 is lifted, and the holding supports 58A and 58B are extracted from the hanging hole E. Further, the flooring materials may be conveyed sequentially from the lower tier side, and the flooring materials may be lowered in the same manner.

In addition, this floor material holding device 21 can adjust the spacing between the holding columns 58A and 58B using the spacing adjustment device 59.
The flooring material may have large dimensions, or it may have a notch formed at the edge of the flooring material in place of the hanging hole E. Furthermore, as shown by the imaginary line in FIG. , holding column 5
It is also possible to make the interval between 8A and 58B extremely small and to hold the beam material F in a horizontal position by the support claws 57. Therefore, it is extremely versatile and can perform a wide range of tasks.

In addition, in the above embodiment, the lift frame 55 was provided on the club cart 9 via the lift support 13 and the horizontal beam 19.
The elevating frame 55 may be provided directly on the club cart 9.
