Abstract

PURPOSE:To make dimensional adjustment easy and to improve efficiency in execution of work by a method wherein wale-connecting members and a diagonal member are provided, and jacks are provided to an upper space and to a lower space respectively on their end parts near the corner. CONSTITUTION:A corner block 2 is formed of wale-connecting members 3 and 4 that are bonded together at one end at a right angle, and is reinforced with a diagonal member 5 that is provided diagonally to connect the wale-connecting members. An upper space 3a is formed to the wale-connecting member 3 so that the end part of a wale 1a can be connected thereto. A lower space 4a is formed to the wale-connecting member 4 so that the end part of another wale 1b can be connected thereto. a jack 6 is provided to the upper space 3a on the end part near the corner, and another jack is provided to the lower space 4a on the end part near the corner. Spacers 8 formed of aluminium blocks or the like are placed in a space on the end of the wale 1a. Then gaps are finally filled by driving the jacks 6.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Use) The present invention relates to corner blocks for mountain retaining shoring.

(Prior Art) Auxiliary pieces are generally used at the corners of conventional mountain shoring in order to make the standard dimensions of the restoration correspond to the dimensions of the site.

However, this method increased the number of bolts and had poor workability.

(Problems to be Solved by the Invention) It is an object of the present invention to provide a corner block for mountain retaining shoring that solves the following two conventional problems, facilitates dimensional adjustment, and improves workability.

(Means for Solving the Problems) In order to achieve the following two objects, the present invention includes: 1. A pair of diagonal connecting members connected at right angles, and a diagonal shrine for diagonally connecting and reinforcing the diagonal connecting members. and an upper space formed in one of the ribbed connecting members, a lower space formed in the other ribbed connecting member, an end closer to the corner of the upper space, and an end closer to the corner of the lower space. This paper proposes a corner block for mountain retaining shoring consisting of a fixed jack.

(Function) (+) Since the corner block of the present invention is equipped with a special stiffener, dimensional adjustment is easy.

(2) The corner block of the present invention has extremely good workability, especially since the dimensions can be adjusted from the angle ζ.

(Example) The corner block of the mountain retaining shoring according to the present invention will be described below according to an example shown in the drawings.

1 and 2 show corner blocks of the present invention,
The corner block (2) has a pair of perpendicular joints (,3X/]) connected at right angles.

The abdominal connection members (3×4) are diagonally connected and reinforced by diagonal members (5).

A two-stage space (3a) is formed in one of the ventral connecting members (3), so that the end of the detachable S (Ia) can be attached thereto.

In addition, a lower space (4a) is formed in the other ventral connection member (4), so that the end of the other detachable S (Ib) can be attached thereto.

Next, a jack (6) is provided at each of the corner end of the upper space (3a) and the corner end of the lower space (4a).

The functions of the corner blocks of the mountain retaining shoring according to the present invention shown in the second embodiment are as follows.

In other words, in the upper space (3a) there is one side S (1a).
and the lower space (4a) has the other end of the S (1
The ends of b) are each attached.

In this state, the standard dimensions of S (Ia) (Ib) generally do not match the on-site dimensions.

Therefore, for example, a spacer (8) such as an aluminum block is inserted into the space at the end of the S (1a).

Next, the jack (6) is driven to finally fill the gap.

(Effects of the Invention) The embodiments of the corner flock of the mountain retaining support of the present invention are as described above, and the effects thereof are listed below.

(1) The corner flock of the present invention is particularly equipped with jacks, so that size adjustment is easy.

(2) The corner block of the present invention has extremely good workability, especially since the dimensions can be adjusted by jacking.

Claims (1)

[Claims] 1. A pair of ventral connection members connected at right angles, a diagonal member that diagonally connects and reinforces the ventral connection members, an upper space formed in one of the ventral connection members, and another ventral connection. A corner block of a mountain retaining support consisting of a lower space formed in a timber, and a jack provided at each of the corner end of the upper space and the corner end of the lower space.
