Joining member (300, 400)

The coupling member 300 includes a fixing pin 310 fitted into the insertion hole 122 and the through hole 222.

5 is a stud bolt 320 that fits into a fixing pin 310, which is a coupling member 300, and mounting grooves 116, 226 of the side surfaces of the flat portions 110 and 210 of the upper and lower blocks 100 and 200. Indicates.

The fixing pin 310 has a body 311 having a constant diameter and having rigidity, and an adhesive elastic body 312 formed at both ends of the body 311.

The close contact elastic body 312 is made of an elastic material, and has a hopper shape that increases in diameter toward both ends, and preferably, the through hole 222 of the pillar part 220 and the insertion hole 122 of the support walls 120 and 121. By being fitted to both, consequently, the pillar portion 220 and the supporting walls 120. 121 are all supported at the same time to further improve the bonding strength.

1 and 3, the coupling member 400 includes anchor bolts 410 and 412 formed at one end thereof, tie bars 420 and 422 having one end connected to the anchor bolts 410 and 412, respectively, and a tie. The other end of the bars 420 and 422 is composed of a turn buckle 430 coupled together.

The other ends of the anchor bolts 410 and 412 are embedded in the support wall 121 of the upper block 100 and the flat plate 210 of the lower block 200, respectively.

By rotating the turn buckle 430, the length of the tie bars 420 and 422 can be adjusted to adjust the tension between the support wall 121 of the upper block 100 and the flat plate 210 of the lower block 200. In addition to controlling the bonding strength, it is possible to adjust the inclination of the upper block 100 with respect to the lower block 200. Accordingly, for example, when adjusting the angle of the flat plate 110 of the upper block 100 in the curved section, it can be simply adjusted using the turn buckle 430.

Hereinafter, the assembly of the expandable block device having the above-described structure will be described.

FIG. 6 illustrates an example of a state of coupling using the extended block device of FIG. 1.

The pillar 220 of the lower block 200 is inserted into the receiving groove 150 of the upper block 100, and the end portions of the support walls 120 and 121 of the upper block 100 have a jaw 223 as shown in FIG. 4. Is supported in contact with

Next, the fixing pin 310 is forcibly pushed in from the insertion hole 122 of the support wall 121. Accordingly, one of the close contact elastic bodies 312 of the fixing pin 310 is shrunk and the insertion hole 122 of the support wall 121, the through hole 222 of the pillar portion 220 and the insertion hole of the support wall 120. The through-hole 222 and the insertion hole 122 are brought into close contact with the inner surface of the through-hole 222 and the insertion hole 122 while being sequentially spread horizontally, and the other close elastic body 312 is also the through-hole 222 and the insertion hole 122. Close contact with the inner surface.

In this state, a constant gap is formed between the outer surface of the pillar portion 220 and the inner surface of the support walls 120 and 121, as described above, the injection hole 114 formed in the surface of the flat plate portion 110 Communicate with the gap.

Accordingly, fillers such as silicon or mortar are injected through the injection holes 114 to further strengthen the coupling between the pillars 220 and the support walls 120 and 121.

As described above, the anchor bolt 410 is embedded in the outer surface of the support wall 121 of the upper block 100, the anchor bolt 412 is embedded in the surface of the flat plate 210 of the lower block 200 Since it is in a fixed state, as described above, the first bar is coupled to the ring of tie bars 420 and 422 to the ring of each anchor bolt (410, 412). At this time, the turn buckle 430 is loosely released as much as possible so that the tie bars 420 and 422 and the anchor bolts 410 and 412 are easily coupled.

When the tie bars 420 and 422 and the anchor bolts 410 and 412 are coupled, the turn buckle 430 is turned to adjust the tension between the pillar 220 and the support walls 120 and 121.

In this way, one module in which the upper block 100 and the lower block 200 are combined is assembled.

Next, assembling a plurality of modules as shown in Figure 6 to complete the assembly. In detail, the mounting grooves 116 and 226 formed on the side surfaces of the flat parts 110 and 210 of the upper and lower blocks 100 of the assembled module have a stud bolt 320 as shown in FIG. 5 (b). One end is fitted and then arranged as shown in FIG.

Subsequently, when the filler (grout) such as mortar is filled in the gap between the modules through the non-shrink grouting operation, the head of the stud bolt 320 has a large diameter, so that the filler is hard to fall off, and thus the flat parts 110 and 210 are separated from each other. It is connected reliably.

Preferably, a connection through hole may be formed in a side surface of the flat plate 210 of the lower block 200, and a tensile strand may be inserted into the connection through hole to more closely couple the adjacent lower block 200.

FIG. 7 shows another example of a state of coupling using the expandable block device of FIG. 1, and FIG. 8 is a perspective view of the gap control member 500.

According to this embodiment, the extended block device 1000 may be installed in a curved section.

In this case, the spacing control member 400 of FIG. 8 may be installed between the adjacent expandable block devices 1000, and a simple mold may be installed at the lower portion thereof, and then the non-contraction grout may be poured.

Here, as shown in FIG. 8, the gap control member 500 includes a pair of diaphragms 510 and 520 and a plurality of bolts 530 and diaphragms 510 and 520 connecting the diaphragms 510 and 520. A nut 550 to adjust the position of the bolt 530 relative to.

Referring to FIG. 8 (b), the distance between the diaphragms 510 and 520 may be adjusted by adjusting the length of the bolts 530 between the diaphragms 510 and 520. That is, by increasing the lengths of the bolts between the diaphragms 510 and 520 in the order of the bolts 531, the bolts 532, and the bolts 533, the diaphragms 510 and 520 have a shape that gradually opens up. At each of the bolts (531, 532, 533) to tighten the pair of nuts (550) on the front and rear of the diaphragm (510, 520) to fix the position.

As such, the interval control member 500 having the adjusted interval may be inserted into a gap between the expandable block devices of FIG. 8 to easily control the interval.

Although the above has been described with reference to the preferred embodiment of the present invention, various changes are possible at the level of those skilled in the art.

For example, in the above embodiment, the coupling member 400 mentioned an anchor bolt formed at one end and a turn buckle structure for tension adjustment.
