That is, the connection block 20 is coupled to the upper end of one end made of pillar blocks 10, and another end made of another pillar block 10 is coupled to the upper portion of the connection block 20. Made of structure.

The pillar block 10 is manufactured in a shape having a flat cross section obtained by dividing the flat cross section of the column.

That is, the pillar block 10 may be manufactured in a shape having an arc-shaped flat cross section obtained by dividing the flat cross section of the circular column, as shown in (a) and (b) of FIG. 3, and (c) and (d). As shown in (e), it may be manufactured in a shape having a rectangular flat cross section obtained by dividing the flat cross section of the square column.

That is, the arc-shaped pillar blocks 11 and 12 are combined in equal numbers to form a cylinder, and the rectangular pillar blocks 13, 14 and 15 are combined in equal numbers to form a square pillar. Will form.

Shear keys 11a, 12a, 13a, 14a, and 15a protruding upward are formed on the upper surfaces of the pillar blocks 11, 12, 13, 14, and 15, and correspondingly, lower ends are formed at the same positions on the lower surfaces. Shear key grooves 11e, 12e, 14e, and 15e into which top shear keys 11a, 12a, 13a, 14a, and 15a are inserted are formed. (See FIG. 7 for shear key grooves.)

In addition, shear keys 21a, 22a, 23a, and 24a formed on the upper surface of the connection block 20 may be inserted into the shear key grooves 11e, 12e, 14e, and 15e. (See FIGS. 10, 11, 13, and 14). )

In addition, the pillar block (11, 12, 13, 14, 15) is formed through the steel wire holes (11b, 12b, 13b, 14b, 15b) in the vertical direction, the pillar block 10 of the upper end and the connection block 20 and the column block 10 of the lower stage can be bound with a steel wire.

In addition, in order to form a hollow pillar having a hollow therein, as shown in (b) and (e) of FIG. 3, an arc-shaped or rectangular hollow ( 12f, 15f) may be formed (exactly an incision for forming the hollow of the pillar, but will be referred to as hollow for convenience).

In addition, in the case of the rectangular pillar blocks 14 and 15, the outer side edges of the pillar may be chamfered as shown in (d) and (e) of FIG. 3. This is to remove the sharp part to improve the safety and aesthetics, and to prevent the edge of the pillar block is easily broken during construction and transportation.

In addition, in the case of the rectangular hollow 15f formed in the rectangular pillar block 15, the corner portions at right angles are filled so as not to have sharp edges on the inner circumferential surface to form obtuse corners. Therefore, it is possible to prevent the occurrence of cracks due to the concentration of stress in the corners.

4 illustrates a state in which the pillar blocks 11, 12, 14, and 15 of the above shapes are coupled to each other to form a pillar.

(A) and (b) of FIG. 4 are examples in which side surfaces of the arc-shaped pillar blocks 11 and 12 are coupled to each other to form a circular column, and (c) and (d) are rectangular pillar blocks 14 and 15. The sides of these fields are combined to form a rectangular column.

When the pillar blocks 11, 12, 14, and 15 are coupled to each other as described above, the shear keys 11c, 12c, and the shear keys 11c, 12c of the other pillar block in the shear key grooves 11d, 12d, 14d, and 15d of one pillar block. 14c and 15c are inserted to suppress lateral flow between the column blocks.

4 (b) and 4 (d) are examples of hollow pillars in which hollows 12f and 15f are formed.

As shown in (b) and (d) of FIG. 4, a circular hollow 12f may be formed in the circular pillar, and a rectangular hollow 15f may be formed in the square pillar. As shown, a rectangular hollow 12f 'may be formed in the circular pillar, and a circular hollow 15f' may be formed in the square pillar.

On the other hand, the pillar blocks forming the same stage as described above, as shown in Figure 6, can be completely engaged with each other by inserting the steel wire 30 in the steel wire hole (11b) by tension. In this case, as described above, the steel wire 30 may couple the upper and lower pillar blocks and the connection block disposed therebetween. (The hollow pillar block 11 having no hollow is described by way of example. However, the same applies to other pillar blocks.)

Meanwhile, as shown in FIGS. 7A and 7C, the shear keys 11c and 14c and the shear key grooves 11d and 14d formed on the side surfaces of the pillar blocks 11 and 14 are the pillar blocks 11. It may be formed throughout the side from the top to the bottom of the (14).

Multiple can be formed. At this time, the position and the number of the shear keys 12c and 15c and the shear key grooves 12d and 15d are the same.

In addition, as shown in Figure 8, the shear key groove 11d may be formed in a wider width than the shear key (11c).

Since the shear key groove 11d is formed wider than the shear key 11c, the tolerance of the size and position of the shear key or shear key groove increases, thereby reducing the possibility of interference between the shear key and the shear key groove when the pillar block 11 is coupled. The pillar block 11 can be more easily coupled. only. At this time, the position of the shear key and the outer end of the shear key groove (end of the outer direction relative to the center of the pillar) should be mutually matched to be in close contact with each other. This is because the above conditions must be satisfied to prevent the flow between the pillar blocks so that the bonding state can be stably maintained. (In the drawing, only the arc-shaped pillar block 11 is not formed. The same applies to the pillar blocks 12, 14 and 15 of the form.)

As shown in FIG. 9, only one shear key 11a and 14a may be formed on the top surface of the pillar blocks 11 and 14, and two or more may be formed as necessary. That is, in the case of the arc-shaped pillar block 11, the shear key 11a may be formed in the middle portion on the concentric circumference adjacent to the outer circumferential surface of the pillar block 11 as shown in (a), (b) As shown in Figure 2 may be formed spaced apart on the same radial line two. In this case, the steel wire hole 11b is formed in equal numbers on both sides of the shear key on the same circumference as the shear key located on the outside.

The protrusions 23i and 24i are formed so that when the rectangular pillar blocks 14 and 15 are inserted into the inner spaces of the reinforcing walls 23g and 24g, the pillar blocks 14 and 15 are inserted into the protrusions 23i and 24i. As the chamfered surface is in close contact with each other, the flow of the pillar blocks 14 and 15 may be suppressed. Thus, the stability of the column is improved.

On the other hand, even in the case of the connecting block may be a circular hollow formed in the circular connecting block, a circular hollow may be formed in the rectangular connecting block is a matter of course. Which type of connection block is to be used depends on the shape of the hollow formed in the column. That is, it is preferable that the hollow shapes of the pillar and the connection block coincide with each other.

FIG. 17 is a rectangular clip 60, in which a steel plate having the same width as the reinforcement walls 23g and 24g (here, means up and down length) is bent into a rectangle (including a chamfer shape of a pillar edge), Flange 61 is formed to be opposite to each other, the flange 61 is coupled by a fastening means, such as bolt 62.

In addition, a protrusion 63 corresponding to the grooves 23h and 24h formed at each center of the outer surfaces of the connection blocks 23 and 24 is formed at the center of each side of the inner side of the rectangular clip 60. That is, the protruding portion 63 performs the same function as the same shape as the protruding portions 23i and 24i of the reinforcing walls 23g and 24g.

FIG. 18 illustrates a structure for connecting the upper end and the lower end of the pillar formed of the pillar block 10 by using the connection block 20 and the clips 50 and 60.

Regardless of the shape of the flat section (regardless of whether it is circular or rectangular), in the case of a simple flat connection block, the connection block 20 is placed on the upper end of the lower end where the column block 10 is coupled as shown in (a). Place it, and put the upper end of another pillar block 10 on the top. In this case, the shear key formed on the upper surface of the lower end is inserted into the shear key groove formed on the lower surface of the connection block 20, and the shear key formed on the upper surface of the connection block 20 is inserted into the shear key groove formed on the lower surface of the upper end to form a column. The lateral behavior of the blocks 10 and the connecting block 20 can be suppressed.

(b) is a case of using the connecting block 20 having the reinforcing wall (21g, 22g, 23g, 24g) formed in the edge, in this case into the space formed by the reinforcing wall (21g, 22g, 23g, 24g) The upper end and the lower end of the pillar block 10 are inserted.

That is, the upper end of the lower end is inserted into the lower space of the connection block 20, the lower end of the upper end is inserted into the upper space of the connection block 20.

Therefore, since the reinforcing walls 21g, 22g, 23g, and 24g surround the interface between the upper end, the connecting block and the lower end of the column, the lateral behavior between the column blocks 10 and the connecting block 20 is completely suppressed. This improves the structural stability of the column.

(c) is a structure for directly connecting the upper end and the lower end consisting of the column block 10, without using the connecting block 20, the shear key of the lower end is inserted directly into the shear key groove of the upper end, the upper The clip (50, 60) wraps the interface between the end and the lower end so as to suppress the transverse flow between the upper and lower ends.

The clips 50 and 60 surround the column, and the flanges 51 and 61 formed at both ends of the clips 50 and 60 are coupled to each other and fastened by fastening means such as bolts 52 and 62 to tighten the perimeter of the upper and lower ends of the column. It is supposed to be.

Therefore, the installation state of the clips 50 and 60 itself is maintained firmly, and as described above, the lateral behavior between the upper and lower pillar blocks 10 can be suppressed to secure the structural strength of the pillar more stably. Can be.

On the other hand, even when using the clip (50, 60), of course, the connection block 20 can be installed between the upper end and the lower end. That is, the clips 50 and 60 are provided in the structure of FIG. Even in this case, the width (up and down length) of the clips 50 and 60 is formed to be the same as the up and down length of the reinforcing walls 21g, 22g, 23g and 24g. The clip 50 and 60 can stably surround the interface.

19 illustrates embodiments of a connection block and a clip applied to a large cross-section pillar.

FIG. 19 (a) shows a hollow blockless connection block 25 and a hollow block 26f having a connection block 25 applied to the large cross-sectional circular pillars shown in FIGS. 10A and 10B. 19 (b) shows that the reinforcing walls 25g and 26g having the structure and function as described above are formed at the edges of the large cross-sectional disk-shaped connecting blocks 25 and 26, and FIG. (C) shows a clip 50 'applied to a large cross-sectional column.

In addition, Figure 19 (d) is a hollow block connecting block 27 and hollow 28f having a connection block 28 is applied to the large cross-sectional rectangular pillar shown in (c), (d) of FIG. 19 (e) shows the formation of the reinforcement walls 27g and 28g having the structure and function as described above at the edges of the large cross-sectional rectangular plate connecting blocks 27 and 28, 19 (f) shows a clip 60 'applied to a large cross-sectional rectangular column.

As shown, even in the case of a large cross section, the connection block 21 having the simple connection blocks 21, 22, 23, 24 and the reinforcing walls 21g, 22g, 23g, and 24g described in FIGS. 22, 23, 24 and the same structure as the clip (50, 60) can be applied as it is.

However, as shown in the drawing, the cross-sectional area of the connection block is expanded to match the enlarged cross-sectional shape and area of the large cross-section pillar, and the circumferential length of the clip is increased.

On the other hand, Figure 20 (a), (b) shows a columnar pillar block, (a) is a columnar pillar block 70 having an arc-shaped flat section, (b) is a rectangular flat It is a columnar pillar block 71 having a cross section.

The columnar columnar blocks 70 and 71 have the same cross-sectional shape and area as the columnar columnar blocks 10 described above, and also have shear keys 70a, 70c, 71a, 71c, shear key grooves 70d, 70e, 71d and 71e, the steel wire holes 70b and 71b, etc. are formed in the same shape.

Further, between the pillar blocks 70 and 71 in such a manner that the shear keys 70c and 71c formed on the side surfaces of the pillar blocks 70 and 71 are inserted into the shear key grooves 70d and 71d of the adjacent pillar blocks 70 and 71. The same applies to the transverse coupling.

In addition, a hollow may also be formed in these columnar pillar blocks 70 and 71.

The columnar pillar blocks 70 and 71 as described above may be used in the case of constructing a pillar of a pier using only one column block. In this case, when the height of the pier pillar is low, the number of pillar blocks to be used can be reduced, so that the pillar construction can be performed more quickly.

In this case, as shown in FIG. 21, the clips 50 and 60 are used to prevent binding and buckling between the pillar blocks 70 and 71. As shown in the drawing, the clips 50 and 60 are installed on the upper and lower portions of the pillar blocks 70 and 71, and in the case where the lengths of the pillar blocks 70 and 71 are further increased, The necessary number of clips 50 and 60 can be provided at appropriate intervals in between.

On the other hand, if the height of the pier pillar is very high to inappropriate to construct the pillar only by stacking the columnar pillar block, a plurality of columnar pillar blocks (70, 71) can be used, in this case using the connection block and clip Thus, the columnar pillar blocks may be stacked in a structure in which (b) or (c) or (a) and (c) of FIG. 18 are combined.

In addition, the columnar pillar block may also form a large cross-section pillar using an intermediate block as shown in Figure 10, in this case, the intermediate block is of course made of a columnar shape.

Meanwhile, FIG. 22 illustrates another assembling form of the column blocks, but illustrates the columnar pillar block 70, but may be similarly applied to the columnar pillar block 10.

This embodiment is characterized in that there is a difference in height between the pillar block 70 is coupled to each other side.

In other words, the side blocks are assembled in a state where they are shifted up and down in a mutually vertical direction so that a step exists between the column blocks 70 coupled to each other.

22 (a) shows an assembly form in which two pairs of quadrangular arc-shaped pillar blocks are divided into two pairs at the same height, and the pairs are coupled with the same height.

In addition, FIG. 22 (b) shows an assembly form in which all four quadrangular arc-shaped pillar blocks are coupled to each other with a step difference. Although an arc-shaped pillar block is illustrated, it can be applied to all pillar blocks having a flat cross-sectional shape by dividing the plane of the pillar such as a rectangular pillar block.

In the embodiment in which the column blocks are coupled with the height difference as described above, the shear key 70a and the shear key groove 70e are formed on the upper and lower surfaces of the pillar block 70, respectively, so that the pillar blocks can be vertically coupled between both sides. In addition, shear key 70c and shear key groove 70d are formed, respectively, so that lateral coupling between the pillar blocks is possible.

The shear key 70c and the shear key groove 70d of the side surface may be formed in plural at regular distances in the vertical length of the pillar block, or may be formed as one over the entire vertical length of the pillar block.

In addition, the clip 50 is fastened to the outer circumference of the pillar blocks 70 coupled as described above to firmly bond the entire pillar.

In addition, when the pillar blocks are coupled to each other in the vertical direction with a step as described above, an empty space is generated between the uppermost pillar blocks and the coping and between the lower pillar blocks and the base portion. Spacer block 80 having the same cross-sectional shape as the pillar block is assembled at the corresponding position.

The spacer block 80 is formed in the same manner as the pillar block, as well as the shape and the steel wire hole of the upper and lower surfaces and both sides as well as the flat cross-sectional shape can be made in the same manner.

As described above, when the pillar blocks are coupled to each other with a step in the vertical direction, the boundary between the upper and lower ends is not formed in one plane, but the position of the blocks is the same. Height), the shear resistance of the column against lateral load (impact) from the outside is increased, thereby improving the structural rigidity of the column.

Also in this case, it is possible to extend the cross-sectional area of the pillar by arranging the intermediate block between the pillar blocks.

As described above, the pillar block, the connecting block, and the intermediate block, which are the main components of the present invention, are standardized and mass produced. Their size, that is, the size of the product is to the extent that it can be transported by using a large truck used in the construction site, it is possible to easily and quickly transport from the manufacturing plant to the construction site.

In other words, the material to be used for the construction of the bridge is ready in advance, when the bridge design is completed, it is possible to immediately assemble the pier satisfying the design specifications by combining the column block, connecting blocks and intermediate blocks as necessary.

Existing prefabricated bridge piers commonly use precast products, but in the past, after the bridge design, the column segment had to be manufactured according to the design specification. The difference is that you can purchase the required pillar block, connecting block and intermediate block to carry out the pier pillar assembly.

That is, the present invention has the effect that the air can be greatly reduced since the construction can be started immediately after the bridge design without the need for a separate period for producing column segments between the bridge design and construction.

In addition, since the pillar block, the connecting block, and the intermediate block of the present invention are smaller than the segments of the conventional prefabricated bridge piers, it is easy to transport and stack in the field, which also helps to shorten the air.

On the other hand, as described above, the present invention is to assemble the pier by combining a plurality of blocks produced in advance relatively small. In addition, it is possible to combine the pillar block, the connecting block and the intermediate block in various ways depending on the site conditions. Although only the case of sequentially repeating stacking of the pillar block and the connection block has been described, depending on the situation, the pillar block and the pillar block, or the connection block and the connection block may be assembled in a manner of sequentially stacking each other.

Therefore, not only the custom assembly is possible through the optimal combination according to various variables such as the size, height, support load of the pier to be constructed, but also the reduction and expansion construction according to the design change can be easily performed.

On the other hand, it is preferable to apply a waterproof material to the interface between the individual blocks, such as between the pillar block and the pillar block, between the pillar block and the connecting block.

As described above, by applying a waterproof material to the connection interface between the blocks to prevent the penetration of moisture into the interior of the pillar can be reduced durability of the pillar.
