Abstract

PURPOSE: To lay a slope face block on a face of slope by arranging the hanging-up part capable of hanging down the slope face block in a desired inclined state on a hanging arm of a hanging-up tool having a block support member projected in the horizontal direction, and hanging the support member up by inserting the support member into a through hole vertivally arranged in the slope face block. CONSTITUTION: The central part of a block holding member 7 of a hanging-up tool (a) having a block support member 2 projected in the horizontal direction, is supported by a hanging arm 4. Balance adjusting hanging-up holes 5' are bored at prescribed intervals in the hanging arm 4. A through hole 3 is vertically arranged in a slope face block (b) so that the support member 2 is inserted into it. After being raised by the proper hanging-up hole 5', the block (b) is hung up while still inclining along a face 1 of slope, and is carried and lowered to a laying place still in its state to be thereby easily laid by only the series of operation.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a method for laying slope blocks, a slope block lifting tool used for laying the slope blocks, and a slope block lifting tool used to lift and move the slope blocks. This is related to the slope block.

[Conventional technology]

Conventionally, in order to lay slope blocks, the slope blocks were lifted up by a lifting device, moved to a predetermined position, and then lowered to lay the slope blocks.

[Problem that the invention seeks to solve]

In this case, since the conventional block lifting tool is a type of lifting tool that clamps and holds the block between opposing clamping arms, the block is first lowered onto the slope in an upright position, and the lifting tool is removed. The blocks had to be knocked down and laid.

That is, if the block is lowered while aligned with the slope, the clamping arms on the lower side of the block will get in the way when the lifting tool is removed, making it impossible to lay the block.

In addition, the method of hanging by tying with wire has the disadvantage that the wire may not come out, and the method of hanging by attaching anchor bolts to the block has the disadvantage that the anchor bolt part is repaired with mortar after installation, which makes it look unsightly. was there.

If it is possible to lower the slope block while maintaining the same slope as the slope, and in that case, the slope block can be lowered without any lifting equipment members on the ground side of the slope block. If it is possible to pass reinforcing bars while suspended, the slope block can be lowered down the slope and the installation can be completed immediately, making it possible to perform the installation work extremely efficiently. .

The present invention provides a laying method, a lifting tool, and a block that solve this problem.

The slope block b and the block lifting tool a are fixed by the connecting tools 13 a and 13 b, and the lifting member 5 provided on the hanging arm 4 is used to lift the block lifting tool a to a lifting machine such as a crane truck. When used and lifted, the slope block b is lifted horizontally and at a desired inclination, that is, slope 1 inclination, due to the setting of the 5° position of the lifting hole.

If the slope block b is lowered in this state, the entire surface of the slope block b will be grounded as there is no member of the block lifting tool a below the slope block b.

At this time, the block support member 2 is a rod-shaped pipe with holes opened at both ends, and the through hole 3 of the slope block b is also opened at both ends, so the reinforcing reinforcing bars C are left hanging as shown in Figure 3. It can be inserted as is.

If the block support member 2 is not a pipe, reinforcing steel C
However, if the through hole 3 is large, it can be inserted into the gap below or on the side.
It is also possible to lower the block support member 2 after inserting the tip thereof, pull out the block support member 2, and then slide it down to a predetermined position.

Therefore, in this state, finishing work required for laying, such as filling with mortar, can be performed.
