JPS60184113A - Bracing method for extension pier - Google Patents

Abstract

PURPOSE:To simplify a work, by a method wherein a chain, having a mounting metal with a turn-buckle, is installed in a bracing manner to the upper and the lower frame on the steel pillars of the titled pier, and the length of a brace is regulated and tightening is effected by the use of the turn-buckle. CONSTITUTION:An uppermost plate is disposed to steel skeletons 1, a hook is engaged with a bored hole in the plate 2 to mount a high-strength chain 3 to a pillar of the steel skeleton 1, and the suspending chain 3 is extended to place bail cans 9 on a pit excavation bottom. Thereafter, after pit excavation is carried out to a given depth, the chain 3 is moved from a position, shown by a dotted line, to a position shown by a solid line, and through control of a turn- buckle 5, the length of a brace is regulated and tightening is performed to mount the plate 2 to the lower end thereof. Further, the same works are repeated in order.

Description

[Detailed description of the invention] The present invention relates to a place construction method for a boarding pier.

The conventional pier place is published by Angle.

Channel material or round steel is used. These steel materials have problems such as a large unit weight, a large amount of welding work required, and the need to provide work scaffolding for this purpose. In addition, as the root-cutting and mountain-stopping work progresses, the strut beams, etc. become intertwined in a complicated manner, and if rearranging occurs, the place must be cut and reattached, which takes two hours and a lot of work. It costs a lot.

The same thing happens when working on underground structures.

The present invention was made mainly in view of the above-mentioned circumstances, and its gist is that a high-strength chain having a mounting bracket with a turnbuckle mechanism at the lower end is attached to the top and bottom of the steel columns of the pier. The chain is installed in the form of a place between the installed mounting plates, and the length adjustment and tightening of the chain place are performed at the same time by operating the turnbuckle, thereby completely eliminating the difficulties in the conventional construction method.

This will be explained in detail below based on the drawings.

That is, Figures 1a to 1e are overall views and detailed views of each main part of the access pier completed using the construction method of the present invention. 3 indicates a high-strength chain installed in a place between the mounting plates 2, 4 indicates a cover plate, and b
In the detailed view of Fig. w, 5 indicates a turnbuckle inserted to introduce tension into the high-strength chain 3;
indicate the respective chassocles.

The high-strength chain 3 is attached to the column of the steel frame 1 by hooking the hook 3' at its upper end into the hole in the mounting plate 2 disposed on the top of the steel frame 1, and attaches its lower end to the mounting plate 2 disposed at the bottom of the opposing steel frame. It is assembled against.

A mounting bracket with a turnbuckle mechanism (turnbuckle 5, shackle 6, and shortening to be described later) is attached to the lower end of the high-strength chain 3 via a length adjustment shortening 8, but only this bracket 41 is attached in advance. Mounting plate 2
It may be attached to the side.

The length adjustment shortening 8 is used to roughly adjust the length, and the turnbuckle 5 is operated to tighten (apply a predetermined tension).

Next, the above-mentioned place construction method will be explained based on the process flowchart shown in FIG.

First, the uppermost mounting plate 2 is placed on the steel frame 1, and the chain 3 is attached to it using the hook 3'fJI.

The hanging chain 3 is stored in the bale can 9 for li.
Cut the root and place it at the bottom. When the chain 3 is cut to a predetermined position, the chain 3 is moved from the dotted line to the solid line position and its lower end is attached to the mounting plate 2. (4 times) Repeat this from now on. (Figure C) According to the construction method of the present invention described above, various features as listed below will be exhibited.

(1) Unlike conventional angle materials, channel materials, or round steel, there is no welding work required to erect a scaffold for installation, and there are advantages in that the installation work is simple and no scaffolding is required.

(2) Welded items are difficult to repurpose because they are too small to cut, but since they are chains, they can be taken off and repurposed, which is incomparably advantageous in terms of material costs.

(3) No welding or lifting required (workability is extremely good).

(You can easily change the 4-inch container.
