Description

Border block of assembled type

The present invention relates to an assembly type boundary block, and more particularly to an assembled boundary block in which an upper body and a lower body are combined by a coupling unit. The present invention also relates to a coupling unit, an upper body, and a lower body provided in such an assembled boundary block.

In general, a boundary block is a block installed between a roadway and a roadway to distinguish between roadway and roadway.

As shown in FIG. 1, the boundary block 10 is a block formed integrally with concrete or stone or the like, and is generally formed into a hexahedral shape.

In order to construct the boundary block 10, the foundation layer 2 is formed by placing concrete on the foundation gravel layer 1, the support layer 3 having a predetermined width is formed on the foundation layer 2 by concrete, Thick mortar layer 4 is formed. The upper surface of the mortar layer 4 is formed to be horizontal so that the boundary block 10 provided on the mortar layer 4 can be leveled. On the other hand, the height of the support layer 3 and the mortar layer 4 is determined according to the height of the boundary block 10 to be applied.

Subsequently, after placing the boundary block 10 on the mortar layer 4, the bottom layer 5 is formed by pouring concrete in front of the boundary block 10. The bottom layer 5 is formed up to a predetermined height of the boundary block 10. The bottom layer 5 prevents the boundary block 10 from moving forward. On the other hand, the boundary block 10 is installed continuously along the road.

After the bottom layer 5 is formed, the backing soil layer 6 and the base sand layer 7 are sequentially formed on the back side of the boundary block 10, and then the interlocking block 8 (the press plate) is provided.

Such boundary blocks are disclosed in Korean Patent Application Nos. 10-2007-0067509, 10-2007-0104103, 10-2008-0002077, and the like.

As described above, most of the boundary blocks 10 are made of concrete or stone. The boundary blocks 10 are damaged due to aging with time, corrosion due to exposure to air pollution, It can be broken. In addition, even if it is not damaged or broken, the upper portion may be discolored and the appearance may not be good.

Thus, if the boundary block 10 is damaged, broken or discolored, the boundary block 10 must be separated from the bottom layer 5 and the mortar layer 4 for the replacement. This separation operation is not easy because of the coupling force between the boundary block 10 and the bottom layer 5 and the coupling strength between the boundary block 10 and the mortar layer 4, There is a problem that it is consumed. The replacement work usually costs about 130,000 to 150,000 won per 1m.

However, since the upper part of the boundary block 10 is exposed to the outside, it is likely to be damaged or damaged, while the lower part of the boundary block 10 is embedded in the concrete, so that breakage or damage is relatively small. Typically, 99% of the damage / breakage occurs at the top of the boundary block 10.

In the case where only a part of the boundary block 10 is broken or damaged, for example, even if only the upper part of the boundary block 10 is broken or damaged, the entire boundary block 10 must be replaced and only the damaged or damaged part can be replaced There is a problem that maintenance and repair costs of the boundary block 10 are increased. Also, there is a problem that the replaced boundary block 10 can not be recycled.

On the other hand, the boundary block 10 must be firmly coupled to the neighboring boundary block 10 to function properly as the boundary block 10. Neighboring boundary blocks 10 are coupled by mortar, which has the problem of weakening over time.

The connecting portion 653 is provided so as to penetrate through the elongated holes 652 and 654 to insert the inserting portion 651 and the supporting portion 655, Lt; / RTI > That is, the connection portion 653 is installed so as to penetrate the long hole 652, is assembled with the insertion portion 651, and the connection portion 653 is installed to penetrate the long hole 654 and assembled with the support portion 655.

The connecting portion 653 is horizontal with the upper surface 21 and the lower surface 41 in the same manner as the connecting portion 150. When the insertion portion 651 is inserted into the upper and lower engagement grooves 42 and 22, the connection portion 653 has a length extending outward beyond the side surfaces 44 and 24.

The coupling member 650 engages the upper and lower bodies 40 and 20 with the same principle as the coupling member of the second embodiment. That is, by inserting the bolt into the bolt hole 656 so as to press the side surface 44 (24), the insertion portion 651 engages the lower body 20 and the upper body 40. It is the same as in the above-described embodiment that the packing member 60 can be installed in the insertion portion 651.

As such, the boundary block according to the present invention is manufactured in a state where the upper and lower bodies 40 and 20 are separated from each other in the factory, and then bonded in the field. Since the upper and lower bodies 40 and 20 are coupled by the bolts 57 and the fixing plate 70, the bolts 57 and the fixing plate 70 are disassembled even after the construction so that the upper and lower bodies 40 and 20 Can be separated. Accordingly, when the upper body 40 is damaged or damaged, or when the upper body 40 is discolored, only the upper body 40 may be replaced. As described above, since the entire upper boundary body 40 can be replaced without replacing the entire boundary block, the replacement cost is much smaller than in the conventional case.

In addition, when only the upper body 40 is replaced with respect to the existing boundary block 10, the construction period is greatly reduced and the social cost loss due to the replacement work can be greatly reduced, and the construction is simple and easy.
