Description

Mid-mist support tie for top-down lift

The present invention relates to a mast middle support tie of a top-down lift suitable for the top-down method, which greatly shortens the air by constructing both underground and ground structures simultaneously when constructing large buildings. will be.

The mast of the top-down lift is unlike the usual lift mast fixed to the ground, so the mast itself must be able to rise and fall according to the depth of the construction site in the basement. It was not possible to use the mast lift support tie of a conventional lift, which simply connected the mast to the building being constructed.

Because the top-down lift is the mast itself, which is raised and lowered by the mast brake kit with the mast driving device. Because it is.

The purpose of the present invention is to prevent the shaking of the mast moving up and down in the top-down lift, as well as to support the mast middle support tie of the top-down lift, which can support the mast to move smoothly. To provide.

The present invention, as illustrated in FIGS. 3 and 4, has the pillar member (at both ends of the bracket 14 having a shape surrounding the pillar members 12 and 12 'on one side of the mast 10). 12) The upper guide rollers 18, 20 and the lower guide roller 22, which are in contact with one pillar member 12, on both inner sides of both wing brackets 16 and 16 'extending toward the 12 and 12' sides. The upper guide rollers 18 ', 20' and the lower guide rollers 22 ', 24' are attached to each other so as to rotate freely and contact the other pillar member 12 '. Is attached to rotate freely, the one of the upper guide rollers 18, 20 and the lower guide rollers 22, 24 and the other of the upper guide rollers 18 ', 20' and lower Between the guide rollers 22 'and 24', intermediate guide rollers 26, 28, 26 ', and 28' are rotatably attached in a direction orthogonal to their axial directions. On both sides of the bracket 14 The fixed parts 32, 32 ', 34, 34', each of which has a pin insertion hole 30 is fixed.

In the present invention, the intermediate guide rollers 26, 28, 26 ', and 28' are pivots 36 fixed in a direction transverse to both wing brackets 16 and 16 ', respectively. ), 36 'are formed in the upper and lower ends of both support bodies 40 and 40', each of which is composed of two support plates 38a and 38b fitted in the center thereof. The middle guide rollers 26, 28, 26 ', and 28' at both the upper and lower ends of both supports 40 and 40 'are swingable with the center axis as In other words, when the pillar members 12 and 12 'of the 10 are moved up and down, that is, at the moment when they start moving upward and downward, only the middle guide roller of one of the upper and lower portions is the pillar of the mast 10. The pillar member 12 of the mast 10 is in contact with the members 12, 12 'and the intermediate guide roller on the other side is momentarily not in contact with the pillar members 12, 12' of the mast 10. ), (12 ') and the mechanical forces between the brackets (14) The pillar members 12 and 12 'of the mast 10 can be lifted and lowered more smoothly.

In the drawings, reference numeral 42 is a connector for fixing the bracket 14 to the underground side wall of the destroyed construction site, 44 is a fixing pin, 46 is a locking pin, and 48 is a mast 10 which raises and lowers itself. The mast bracket includes a mast drive device.

This invention is a pillar member 12, 12 'on one side of the mast 10, which is raised and lowered by the mast bracket kit 48 fixed to the ground as illustrated in the first, third and fourth degrees Top guide rollers 18, 20 constructed so as to be freely rotated on the upper and lower portions of both wing brackets 16 and 16 'at both ends of the bracket 14, which is fixed to the base wall of the construction site. ), (18 '), (20') and lower guide rollers (22), (24), (22 '), (24') and intermediate guides arranged freely in a direction perpendicular to their axial direction Since the rollers 26, 28, 26 ', and 28' are rotated in the longitudinal direction, the mast 10 can be held so as not to be shaken, as well as the mast 10. Allows you to move up and down smoothly.

The present invention is the pillar members 12, 12 'on one side of the mast 10, which is raised and lowered by the mast bracket kit 48 fixed to the ground upper, lower guide rollers 18, ( 20, 22, 24, 18 ', 20', 22 ', 24', and images of supports 40, 40 'pivoted to allow swing. The middle guide rollers 26, 28, 26 ', and 28' are arranged at the lower end, and are made of a bracket 14 fixed to the base side wall of the construction site. 10) to support the shaking and the smooth movement of the mast (10), as well as to facilitate the movement, especially when the mast (10) starts to move up and down, the intermediate guide roller (26) is allowed to swing the shock (26) ), (28), (26 '), by buffering (28') has the advantage of not giving a mechanical flock.
