Problems solved by technology

Therefore, there is a problem that the ring member is expensive but cannot be reused
[0013] (2) Concrete will not corrode, but ring members made of metal may corrode
Such a structure in which the eye member receiving recess must be formed makes concrete block fabrication difficult and increases construction time
[0015] (4) After a large concrete block has been placed in a predetermined position, if a long period of time has elapsed, the ring members are prone to corrosion
Therefore, when the large concrete block needs to be lifted again, it may not be possible to lift the large concrete block
[0016] (5) If the force for fixing the eye member to the large concrete block is insufficient, the eye member may be undesirably removed from the large concrete block while lifting the large concrete block, and thus cause an accident
In this case, large concrete blocks that have been dropped or impacted will become unusable

Abstract

Disclosed herein is a large concrete block for crane lifting. The large concrete block includes a large concrete block body (110) made of concrete, and a connection-wire-rope insert tube (120) made of synthetic resin. The connection-wire-rope insert tube is embedded at a medial portion thereof in the concrete block body in such a way that opposite ends of the connection-wire-rope insert tube are disposed at an upper surface of the concrete block body and oriented upwards. The present invention having the above construction can solve problems which have been caused in the conventional technique that uses a lifting eye member.

Description

technical field [0001] The present invention relates generally to large concrete blocks, methods for manufacturing the large concrete blocks and methods for installing the large concrete blocks, and more particularly to large concrete blocks lifted by a crane. Background technique [0002] Large concrete blocks are widely used in various fields such as port construction work, pipeline work and the like. [0003] Large concrete blocks generally refer to concrete structures. Hereinafter, although a large concrete block used for port construction work will be described as an example of such a large concrete block, the present invention is not limited thereto, and all kinds of concrete structures lifted by a crane fall within the scope of the present invention Inside. [0004] exist figure 1 and figure 2 The large concrete block 10 shown in has an eye member 20 in its upper surface for use when the large concrete block 10 is lifted by a crane. [0005] Since one large conc...
