The present invention relates to a concrete block assembly for an arch structure that has a structure in which a plurality of concrete blocks are connected in an arch direction and is used to construct an arch structure such as an arch bridge, an arch girder, an open tunnel, and an arch structure constructed using the same It relates to a construction method, specifically, it has a configuration in which a plurality of concrete blocks are sequentially arranged in the direction in which an arch is formed ("arch direction") and the concrete blocks are connected with a rotatable external hinge connector, so that the concrete block is an external hinge connector Prevents damage to the upper part of the concrete block or lifting at both ends of the arch structure when the concrete block assembly for arch structure is lifted in an arch shape by having a segmented structure that can rotate freely with In addition, since the concrete block at both ends of the arch direction is integrally provided with guide cone members, there is no need for wire pulling that pulls both ends of the arch structure when the arch structure is mounted on the foundation. "Using an external hinge connector, which can efficiently and firmly combine adjacent arch structures in the transverse direction by using an external hinge connector when a plurality of arch structures are arranged in the transverse direction." It relates to a concrete block assembly for building an arch structure having a block connection structure, an arch structure constructed using the same, and a construction method thereof.

As a bridge or medium- and small-scale open-covered tunnel, an arch-shaped arch structure curved upwards convexly is used. Republic of Korea Patent No. 10-1157638 discloses that a plurality of concrete blocks having a rectangular cross section are arranged in a row in an arch direction, and the plurality of concrete blocks are integrated using a fiber mesh connecting material to form an assembly, and then transported to the site. A technique for constructing arch structures such as bridges, tunnels, and arched roofs is introduced by lifting them with a crane and installing them to form an arch. For convenience, an assembly made by integrating a plurality of concrete blocks is described as a "block assembly", and an arch-shaped structure made by lifting the block assembly is described as an "arch structure".

In this prior art, since the connecting material is made of a fiber mesh, it has only a purpose and function for simply connecting a plurality of concrete blocks, and there is no function of reinforcing the rigidity of the block assembly in the arch direction. As an alternative to this problem, a technology of connecting concrete blocks with reinforcing bars and installing steel wires in the arch direction has been proposed. In the case of this prior art using reinforcing bars and steel wires, although it is effective for reinforcing the rigidity of the block assembly, when the block assembly is lifted to create an arch structure in the shape of an arch, tension is generated in the reinforcing bars or steel wire, which may cause local damage to the concrete block this is very high In addition, when an arch structure is made by lifting the block assembly, the concrete blocks located at both ends of the arch structure in the arch direction are lifted upward due to tension generation.

In this case, when the arch structure is mounted on the base located on both sides of the arch direction, in order to maintain the arch shape of the arch structure as designed and ensure that both ends are accurately positioned on the base, both ends of the arch structure are placed at the center of the arch. In other words, it is necessary to perform a wire pulling operation in which the wire is pulled in the central direction by tying the wire to both ends of the arch structure, which causes inconvenience in construction and consequently increases the construction cost and air time. do. In addition, in the process of making both ends of the arch structure positioned on the base, the arch structure may be overturned, or both ends may not be accurately positioned on the base.

In constructing a structure using an arch structure, when arranging and integrating a plurality of arch structures side by side in the transverse direction (direction orthogonal to the arch direction), it is convenient and efficient to And it is necessary to firmly integrate, and the prior art does not yet provide a sufficient solution for this.

By being embedded in the concrete when the concrete is poured on the 100, the anchor function to further strengthen the integration between the block assembly 100 and the concrete to be poured on the block assembly 100 is exhibited. Although not illustrated in drawings. When the external hinge connector (2) is coupled to the hinge fixing anchor plate (3) in which the transverse binding fastening holes (32) are not formed at both ends in the transverse direction and the transverse ends do not protrude outside the transverse edge of the concrete block Also, the same method as described with reference to FIGS. 7 to 9 is applied.

10 is a schematic perspective view showing that a plurality of concrete blocks 1 are bent in various shapes in a state in which they are integrally connected by an external hinge connector 2, and as shown in the drawings, the block of the present invention In the assembly 100 , the adjacent concrete blocks 1 may be rotated in the vertical direction to be bent by using the portion where the two plate members are connected in the external hinge connector 2 as a hinge point. When the block assembly 100 is completed, it is placed on the ground in the same state as in FIG. 1 . In order to construct a structure such as a bridge using the block assembly 100, an external hinge connector 2 is used using a lifting device such as a crane. The block assembly 100 is lifted in the upper state. Since the adjacent concrete blocks 1 in the block assembly 100 are connected in a form that can be rotated and bent in the vertical direction at the point where they are connected to each other, when the block assembly 100 is lifted, the external hinge connector (2) The first rotating body 21 and the second rotating body 22 are connected to each other as a hinge point so that the both sides of the concrete block 1 rotates, and accordingly, it is naturally bent at the hinge point between the concrete blocks 1 The block assembly 100 forms an arch structure having an arcuate shape conforming to the designed shape as shown in FIG. 2 . In the present invention, it is possible to prevent the occurrence of a phenomenon in which local damage is caused to the concrete block due to tension generated in the reinforcing bar or steel wire when the block assembly is lifted and made into an arch shape and the phenomenon that both ends of the arch structure are indented. do.

On the other hand, in the present invention, the end concrete block positioned at each of both ends of the arch direction of the block assembly 100 may be integrally provided with a guide cone member 4 as necessary. 11 is a schematic perspective view of the circle B portion of FIG. 1 showing the installation configuration of the guide cone member 4, and FIG. 12 is a schematic lateral side view of the portion shown in FIG. . In the case of an end concrete block located at both ends of the block assembly 100 in the arch direction, an expansion flange part 120 extending in a vertical direction is further formed on the upper body 12, and the expansion flange part 120 has The guide cone member 4 may be integrally provided in a shape protruding toward the end in the arcuate direction. The guide cone member 4 may be formed of a conical member that becomes sharper toward the end in the arcuate direction. The guide cone member 4 may be provided in plurality.

When the guide cone member 4 is provided in this way, as shown in FIG. 12 , the arcuate side of the end concrete block moves in the arch direction of the adjacent concrete block while the weight of the guide cone member 4 acts in the vertical direction. It naturally comes into close contact with the side and helps greatly in forming the designed arc shape of the block assembly 100 . That is, a vertical load is applied to the end concrete block in the vertical direction as shown in FIG. 12 by the weight of the guide cone member 4 provided in the end concrete block. The moment force due to the weight in the expressed form acts. This moment force causes the end concrete block to adhere well to the adjacent concrete block in the arch direction without being lifted up. Therefore, the block assembly 100 naturally forms an arch shape conforming to the design without lifting both ends in the arch direction, and when installing the arch structure having an arch shape on the base part 5, both ends of the arch structure The advantage of being able to improve the efficiency of the installation work is exhibited by eliminating the need for a wire pulling operation to pull it toward the center of the arch.

Hereinafter, a process of constructing an arch structure such as a tunnel or a bridge by making the block assembly 100 of the present invention into an arch-shaped arch structure and arranging a plurality of them consecutively in the lateral direction will be described.

13 is a schematic perspective view showing a state of constructing an arch structure by lifting the block assembly 100 of the present invention and installing it between the base parts 5, and in FIGS. 14 and 15, respectively, the circle of FIG. 13 A schematic lateral side view of part D is shown. 14 shows a state before the guide cone member 4 is inserted into the guide hole 50 , and FIG. 15 shows a state after the guide cone member 4 is inserted into the guide hole 50 .

When the guide cone member 4 is provided in the end concrete block, the end concrete blocks are in contact. A guide hole 50 into which the guide cone member 4 is inserted is concavely formed on the upper surface of the base 5 . In this configuration, when the block assembly 100 in an arcuate state is mounted on the base 5 , the guide cone member 4 is inserted into the guide hole 50 and fixed. After the guide cone member 4 is inserted into the guide hole 50 , if necessary, the guide hole 50 is filled with a filling material such as mortar so that the guide cone member 4 is inserted into the guide hole 50 . fasten firmly.

The coupling configuration of the guide cone member 4 and the guide hole 50 exhibits the advantage of allowing the block assembly 100 to be mounted on the base part 5 at a predetermined position more easily. When the size of the guide hole 50 is sufficiently large, the guide cone member 4 is easily inserted into the guide hole 50 even if an error occurs during manufacturing or construction, and the block assembly 100 is positioned at the base ( 5) is mounted on In this way, when the block assembly 100 is mounted on the base 5, the guide cone member 4 is firmly fixed in a state inserted into the guide hole 50, so that during the mounting process of the block assembly 100, conduction, etc. can effectively prevent accidents from occurring. In particular, since the upper surface of the base part 5 in contact with the end concrete blocks 1-3 as shown in the drawings is made of an inclined surface, when the block assembly 100 is mounted on the base part 5, the guide cone The member 4 is easily inserted into the guide hole 50 in an oblique direction. When the diameter of the guide hole 50 and the diameter of the guide cone member 4 are made the same, the block assembly 100 is placed in an accurate position while the guide cone member 4 is fitted and fixed in the guide hole 50 . However, if the size of the guide hole 50 is sufficiently large as mentioned above, the block assembly 100 is not placed in the correct position immediately after the guide cone member 4 is inserted into the guide hole 50, but manufacturing or construction Even if a time error occurs, the guide cone member 4 can be easily inserted into the guide hole 50 , and after the guide cone member 4 is inserted into the guide hole 50 , the position of the block assembly 100 . After adjustment, by filling the guide hole 50 with a filler such as mortar and fixing the guide cone member 4 in the inserted state in the guide hole 50 , the block assembly 100 can be firmly installed.

As illustrated in FIG. 13 , the block assembly 100 is lifted into an arch shape and installed between the base portions 5 at both ends in the arch direction, and a plurality of block assemblies 100 are sequentially arranged in the transverse direction, such as tunnels, bridges, etc. Build an arch structure.
