Abstract

PROBLEM TO BE SOLVED: To solve a problem in conventional movement of a heavy block where in it is necessary to recess a hanging anchor burying part such as a top surface of the block for the height of a hanging ring part, which complicates forming to increase cost, and it is further necessary to produce an anchor hanger apart from the concrete block body. SOLUTION: From a tip part of a main body wherein an engagement hole 1a to be engaged with a hook part 5 of a hanging wire is provided, open branches 2 opening at a predetermined angle extends downward almost vertically with respect to the main body kept in horizon. A bent hook body 3 is provided on respective tip parts of the open branches 2. The bent hook body 3 is inserted into a hooking hole 8 provided on a predetermined position on a back surface or the like of the block in such a way of forming an acute angle from an opening part at an interior angle in order to hang and move the block. During forming the block, the hanging anchor burying part is formed by recessed for the height of the hanging ring.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for easily moving a concrete block to a predetermined position, an apparatus therefor, and a block provided with a hooking structure corresponding to the apparatus.

[0002]

2. Description of the Related Art Conventionally, a heavy block is moved by forming a suspension ring on an upper portion at the time of molding the block, embedding a suspension anchor having a lower portion in an anchor shape at a predetermined position of the block, and suspending a hook such as a crane. A method has been adopted in which the suspension ring is hung on the body and lifted and moved.

[0003] In addition, a stacking block provided with reinforcing bar insertion holes penetrating vertically in parallel to the left and right,
A pair of left and right forks are inserted deeply into the reinforcing bar insertion holes, and a holding member provided on the upper part of the fork and a hanging metal provided on a holding mechanism for holding the block by the fork are provided.
There is also a method of lifting and moving.

[0004]

However, in the conventional suspension anchor embedding method, if the suspension anchor is simply embedded, the suspension ring portion protrudes from the upper surface of the concrete block or the like, and is joined to the upper and lower blocks to be stacked. Since the projecting suspension anchors hinder the stacking of the blocks, it becomes necessary to form the suspension anchor embedded portion such as the upper surface of the block by recessing the height of the suspension ring portion, which complicates the molding. There was a problem.

[0005] In addition, since a suspension anchor must be manufactured separately from the concrete block main body, there is a problem that the cost is increased accordingly.

[0006] Further, the method of using the reinforcing bar insertion hole is as follows.
It cannot be applied to a concrete block which requires a complicated clamping mechanism requiring skill in operation, and which has an independence in stacking fitting and does not need to provide a reinforcing reinforcing bar insertion hole.

[0007]

SUMMARY OF THE INVENTION According to the present invention, there is provided a main body having a base portion provided with an engaging hole for engaging with a hook of a hanging wire. Inserting and hooking the bent hook body of the hanging metal fitting having the bent hook body formed at each end of the expanding branch to be expanded into the hook hole provided at a predetermined position such as the back surface of the block from the opening at an acute angle from the opening. It is designed to be lifted and moved.

[0008] With this configuration, a complicated work such as a complicated formwork or spacer is not required, such as forming the suspension anchor embedded portion by the height of the suspension ring portion at the time of forming the block. The main body can be formed without specially forming the structure of the lifting portion only by setting the fitting block forming the shape at a predetermined position in the mold.

Further, the hanging fitting is suspended substantially perpendicularly to the horizontal body from a tip end of the main body having an engagement hole with a hook of a hanging wire at the base, and is expanded downward by a predetermined angle. By adopting a simple shape with bent hooks at each end of the expanding branch, it is possible to insert the bent hooks into the engaging holes of the target block without performing complicated operations such as holding the target block. The target block can be moored at the hook of the suspension wire.

[0010] Further, a block anchoring structure is formed at a distal end portion of the expanding branch that hangs down at a substantially right angle with respect to the horizontal body and expands downward, so that the base engaging hole has a hook of the hanging wire. When the hook is hung on the portion, the bent hook body is inclined in a direction supporting the weight of the block to further deepen and strengthen the hook.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a hanging bracket main body in the block moving device according to the present invention, which is formed with expansion branches 2 and 2 that hang down at substantially right angles to the horizontal body 1 and expand downward. The bent hooks 3 are formed.

Reference numeral 6 denotes an example of a block to be moved, in which a fitting recess 61 and a fitting protrusion 62 are formed on the upper surface, and a corresponding fitting protrusion 63 and a fitting recess 64 are formed on the bottom surface. It is formed such that the fitting recess 61 is fitted to the fitting projection 63 on the bottom of the upper block and the fitting projection 62 is fitted to the fitting recess 64 of the bottom of the upper block at the time of stacking, so that the engaging force is applied. Since a predetermined retaining wall is formed only by stacking and stacking the bottom surface of the upper block on the upper surface of the lower block, the reinforcing bar insertion hole is not formed.
The front surface 65 is provided with a decoration 7 imitating a stone wall and a frame-shaped design.

On the back surface 66 of the target block 6, a bent hook engaging hole 8 formed by making an inner angle 67 an acute angle from the opening is formed at a predetermined balance position on the left and right sides.

On the other hand, an engaging hole is formed in the base of the hanging metal body 1.
1a, 1b and 1c are drilled, and one of them is
One is selected and is engaged with the hook 5 of the suspension wire via the auxiliary wire 4.

That is, when the engaging hole 1a is selected, the gravity of the block 6 supported by the expanding branches 2 and 2 causes the distal end 11 of the main body 1 to be pushed down, and the expanding branch The blocks 6 are lifted up with the rear end 66 raised gently and the back surface 66 is gently inclined. However, when the engagement hole 1c is selected, the load applied to the front end 11 of the main body 1 is reduced. Therefore, the back surface 66 of the block 6 is lifted almost vertically.

The hanging bracket body can be formed very easily by using a metal plate as shown in the figure, but it is a matter of course that other materials may be used.

The bent hooks 3, 3 are connected to the expanding branches 2, 2,
May be left in the shape of a hook, but in this case, the engaging hole 8 formed in the target block 6 must be formed in a shape inclined in a C-shape, so that it is particularly necessary to increase the engaging force. In the case where there is no bent portion, as shown in FIG.

According to the present invention, the above-structured hanging fitting is connected to the hook 5 of the hanging wire of the lifting / moving device such as a crane or a hoist via the auxiliary wire 4, and is connected to the engaging hole provided in the block. By simply inserting the hook portion of the bent hook 3, it is possible to reliably support the weight of the block and lift and move the block to a predetermined position.
