Abstract

PURPOSE:To repeatedly use temporarily installed materials and instruments as often as possible with a rod for suspension in lifting up to omit complicated traffic lines of each material on turning rod and mechanize the construction in order to pursue the economical effects. CONSTITUTION:A receiving beam 1 for lifting up is divided in the horizontal direction to separate each beam 1A from others in the horizontal direction and keep a distance within which the beam does not contact an upward actual post T of the next section. After an actual post C is erected and jointed in the support space, the receiving beam 1, suspending tool 4 for the receiving beam and the lifting up rod 2 are raised and the beam 1A horizontally separated at the top of the actual post C is closed again to finish the turning of rod.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for climbing a lift-up suspension rod, which is applied to a lift-up construction method in which high-rise and multi-layer lift rods need to be refilled.

[0002]

2. Description of the Related Art FIG. 1 shows, as a first example of a conventional method, a clumping process of a lift-up suspension rod in a lift-up construction method. As shown in FIG.
The wire strand 102 mounted and fixed on 01 is pulled up by the jack 103 mounted on the temporary stage S, and the receiving beam 105, the column 106, and the temporary column 101 on which the stage jack 104 mounted on the temporary column 101 is mounted. At the same time to bring up the state shown in FIG.

At this time, the stage jack 104 is in a loose state so as not to mesh with the rod 109. Next, the main pillar 110 is inserted and fixed between the temporary pillar 101 pulled up as described above and the lower main pillar 107, and then the temporary pillar 101 is actuated by the jack 103 as shown in FIG. It descends and is mounted on the upper part of the main pillar 110, and these pillars are used as reaction force support receivers for the jack 104.
By pulling up the rod 109, the stage S is pulled up to complete a series of operations.

As a second example, as shown in FIGS. 1 (d) and 1 (e), the rod receiving beam 1 installed on the top of the main installation column 111.
When the lift-up of the temporary stage (S) fixed to the jack 114, which is engaged with the rod 113 suspended from 12 and is raised, is completed, the bar 115 is pushed out and the main pillar 1
After the beam end 116 fixed to 11 is chinted and stabilized, the rod 114 receives the rod receiving beam 112 and the rod 1 from the jack 114.
13 is pulled out by a heavy machine and the rod receiving beam 112, the rod 113, and the next nodal column 1 are assembled at the place where the next nodal column 117 is assembled.
As shown in FIG. 1 (b), 17 are combined and transported by a hoist (Ho).
Was inserted into the jack 114, and then the next node pillar 117 was joined to the top of the main installation pillar 111 to perform a series of operations for the next lift-up.

[0005]

In the case of the first example,
Each column must be equipped with a temporary column and a climbing device for the temporary column, and the amount of temporary materials becomes extremely large, which requires a lot of time for equipment and dismantling at the final stage, which is economically burdensome. Is big. In the case of the second example, usually, the rod must be pulled out from the jack, the receiving beam must be removed from the main column, and then the column of the next section must be installed and reassembled.

The present invention has been proposed in view of the above-mentioned problems of the prior art. The object of the present invention is to use temporary materials and machinery as repeatedly as possible to reduce the number of installations and refill. Omit the complicated flow line of each material at the time,
An object of the present invention is to provide a climbing method for a lift-up suspension rod in a lift-up construction method that is suitable for mechanized construction and has excellent workability and economy.

[0007]

In order to achieve the above-mentioned object, according to the method of the present invention, the lift-up receiving beam is divided in the horizontal direction, and the respective divided pieces are separated in the horizontal direction. After maintaining the gap distance that does not contact the next nodal column of the next nodal column, after the completion of the joining of the next nodal column to the holding space, pull up the receiving beam and the receiving beam lift-up rod, and horizontally separate to the top of the next nodal column. The divided pieces are closed again to complete the refilling of the rod.

Further, in the apparatus according to the present invention, the lift-up receiving beam is divided and separated without changing the planar position of the lift-up rod, and the lift-up receiving beam split piece is opened so as to maintain the space through which the column can pass. A beam receiving device having a separating and closing mechanism,
It is characterized by comprising a power receiving means and a power transmission mechanism for separating and closing the receiving beam divided pieces from each other, and a receiving beam suspension including the receiving beam suspension lock means.

[0009]

Since the present invention is constructed as described above,
Operate a gate-type crane on the stage to suspend the column to be built next from the crane and the support beam suspension device in a concentric manner, and suspend the support beam suspension device at the column connection position to receive the beam. After locking the gripping tool with the gripping tool, the load is released by slightly pulling up the receiving beam, and the opposing surfaces of the pair of separating pieces of the lifting beam are lifted by the power means equipped on the receiving beam suspension tool. Separate horizontally so that it does not contact the outer circumference of the main pillar.

Next, the pillar of the next section is suspended from the portal crane and joined to release the engagement between the lift-up jack and the rod, and surrounds the new pillar with the receiving beam and rod locked to the receiving beam suspension. At the top of the new post that has just been pulled up and built up, the power means equipped on the receiving beam suspension is operated in the opposite direction to the front direction, and a pair of separating pieces in the receiving beam for lift-up is operated. , And install the same beam on the top of the new column to complete the reshuffling of the rod,
The lift-up rod is again engaged with the lift-up jack to prepare for the next lift-up.
