Block attached with stone and apparatus for manufacturing the same}

The present invention relates to a stone-attached block and a block molding frame for manufacturing the same, and more particularly, a stone-attached block and a block molding frame for manufacturing the same, which have a structure in which masonry coupling force can be strengthened by engagement coupling during masonry. It is about.

In general, widely used blocks are manufactured by molding into mortar in a straight line. Recently, blocks with natural stone have been used on the outer surface of the straight block to enable traditional stone wall-type fence facilities. Various methods for manufacturing such natural stone-attached blocks have been proposed, and Korean Patent Publication No. 2002-0002352 discloses a first cement block and a second cement block paired to form a straight block by mutual coupling. have. However, the block disclosed in Korean Patent Laid-Open Publication No. 2002-0002352 manufactures the first cement block and the second cement block, respectively, and then attaches to the mortar secondarily in a fitted state, thereby complicating the manufacturing process. After the paired first and second block moldings are attached to each other, the bonding force between the blocks may be weakened. In addition, such a straight block has a disadvantage in that the masonry strength of the transverse direction due to wind pressure, earthquake, such as a typhoon during the construction of the fence is weak.

The present invention was devised to improve the above problems, and an object thereof is to provide a block with a stone having a structure capable of increasing masonry strength.

Still another object of the present invention is to provide a block forming mold for manufacturing a block having a structure capable of increasing the masonry strength.

Hereinafter, with reference to the accompanying drawings will be described in more detail a block with a stone according to a preferred embodiment of the present invention and a block forming mold for manufacturing the same.

1 is a perspective view showing a block according to an embodiment of the present invention.

Referring to the drawings, the block 10 is formed in a T-shape having a horizontal portion 11 and a first vertical portion 15.

The horizontal portion 11 is a straight portion extending in the horizontal direction of the T-shaped block 10, the first vertical portion 15 is a portion extending to protrude vertically from the horizontal portion (11).

The horizontal portion 11 is formed in a rectangular parallelepiped shape, and grooves 12 are formed in the central portions of both sides so as to extend vertically. The recess 12 may be omitted.

The first vertical portion 15 is formed in a rectangular parallelepiped shape upward from a central portion of the upper surface of the horizontal portion 11 so as to occupy part of the upper surface of the horizontal portion 11.

The first vertical portion 15 is narrower than the length of the horizontal portion 11 in the lateral direction, and the width of the first vertical portion 15 is the same in the front-rear direction.

In the central portion of the upper surface of the first vertical portion 15, a through hole 16 penetrating the horizontal portion 11 vertically from the first vertical portion 15 is formed. The through-hole 16 is to provide a space in which the elements for strengthening the support force of the block or the coupling element for coupling between the blocks when the block 10, like the groove 12 is inserted.

The natural stone 18 is attached to the front surface 13 and / or the rear surface 17 of the block 10 formed by the horizontal portion 11 and the first vertical portion 15 in a tee shape. Of course, instead of the natural stone 18, other members that can enhance artificial stone or other natural beauty can be attached. In addition, of course, in order to use the block 10 for the construction of the outer wall of the building it can be used in the form attached to the natural stone 18 only on the front.

Such a t-shaped block 10 is preferably formed integrally, when the natural stone 18 is made of a double-sided block attached to both sides 13, 17, the front layer 10a, body layer 10b And a back layer 10c.

The body layer 10b is formed of a mortar having a normal gray color, and the front layer 10a and the back layer 10c are mixed with elements having a different color from the body layer 10b, for example, white or other colors. Formed of mortar or other material. When the front layer 10a and the rear layer 10c are formed of white mortar, white cement, sand, and water may be formed by mixing at a known mixing ratio. In the case of manufacturing the block 10 in a wet manner, a material kneaded with sand and cement in a slime state may be used instead of mortar.

The t-shaped block 10 can be constructed by assemble to block the mutual fit.

On the other hand, a cross-shaped block according to another embodiment of the present invention that can be combined with the tee-shaped block 10 to improve the bonding force is shown in FIG. Elements having the same function as in FIG. 1 are denoted by the same reference numerals.

Referring to the drawings, the cross block 20 includes a horizontal portion 11, a first vertical portion 15, and a second vertical portion 25.

The second vertical portion 25 extends downward to protrude a predetermined length from the bottom surface of the horizontal portion 11 which is opposite to the first vertical portion 11 with respect to the horizontal portion 11 so as to have a hexahedral shape.

Preferably, the second vertical portion 25 is preferably formed to have the same size as the first vertical portion 15.

The natural stone 18 is attached to the front surface 23 and / or the rear surface 27 of the block 20 formed crosswise by the horizontal portion 11, the first vertical portion 15, and the second vertical portion 25. It is. As described above, instead of the natural stone 18, other members that may enhance artificial stone or other natural beauty may be attached.

The through hole 26 is formed so as to vertically penetrate the horizontal portion 11 and the second vertical portion 25 from the central portion of the upper surface of the first vertical portion 15.

Such cross-shaped block 20 and te-shaped block 10 may be used in appropriate combination so as to be engaged with each other when constructing a fence or an outer wall.

FIG. 3 is a fragmentary front view showing an example of a fence constructed using the blocks of FIGS. 1 and 2.

As can be seen from the figure, the illustrated masonry structure combines the T-shaped blocks 10 in a row in a horizontal direction so as to expose the natural stone to the front floor for one floor, and the upper T-shaped block layer in contact with the floor. The cross-shaped block 20 is sequentially assembled to a desired height and then tee-shaped block 10 is inserted into the top layer in an inverted form so as to face the bottom layer. The vertical portion of both ends of the fence is finished with a T-shaped block (10).

In the case of the fence constructed in this way, the lines 30 connecting the mutually joining portions of the blocks in the transverse direction are formed in a staggered zigzag form rather than extending in a straight line like a conventional straight block, so that the length of the fence is constructed. The contact area is increased by lengthening the overall length of the joints between the blocks. As a result, it provides much higher strength than straight blocks against impacts applied in the horizontal direction.

In addition, since the lines 40 connecting the coupling portions between the blocks treated with the mortar in the vertical direction are connected in a zigzag form, the coupling force in the longitudinal direction can also maintain the same strength as in the transverse direction.

In addition, the cross-shaped block 20 and the T-shaped block 10 can be constructed by fitting a rectangular fence with only two types of blocks, and in the case of a conventional straight block, an empty space at the end part of a British stacking or a Dutch stacking construction There is an advantage that no quadrant or dividing block required to fill the gap is required.

In addition, the through-holes 16 and 26 formed in the blocks 10 and 20 themselves and the holes 12 formed to face the recesses 12 opposite to each other in the stacked state may extend the extension holes 36 formed vertically. As a reinforcing member, the iron rod 50 and / or mortar may be additionally inserted to reinforce the bonding force of the constructed fence.

On the other hand, the T-shaped block 10 and the cross-shaped block 20 is preferably formed so that they can be fitted to match each other when stacked in the masonry shown.

4A and 4B are front views of the blocks of FIGS. 1 and 2 for explaining the size conditions of the blocks for the blocks of FIGS. 1 and 2 to be mutually matched and engaged when structuring the structure of FIG. 3.

In the drawings, parts denoted by the same letter indicate the same size.

Extension of the vertical portions 15 and 25 with respect to the horizontal portion 11 in each of the blocks 10 and 20 as can be seen through the portions written in English for each portion of the blocks 10 and 20 in the figure. The lengths of the portions e coincide with each other, and the lengths of the portions C extending from the vertical portions 15 and 25 to both ends of the horizontal portions coincide with each other. Various lengths may be applied to each portion of the T-shaped block 10 and the cross-shaped block 20 having such a length ratio. As an example, a part 385 mm, b part 185 mm, c part 96.3 mm, d part 192.4 mm, e part 40 mm, f part 145 mm may be applied. For reference, when a part and b part are applied to 385 millimeters and 185 millimeters, respectively, the rectangular section divided by a dotted line corresponds to a conventional straight block.

In addition, the length of each part of the block 10, 20 is appropriately considered in consideration of the filling amount of the mortar filled for bonding between the cross-shaped blocks of the same type or between the cross-shaped block 20 and the T-shaped block 10. Of course, it can be made slightly different from the above described.

On the other hand, as can be seen through Figures 4a and 4b the block according to the present invention can be kept the same but the contact area of the block is smaller than the conventional straight block partitioned by the dotted line, as a result the contact area between blocks Increase.

An example of a block forming mold for manufacturing such a block is shown in FIG. 5.

Referring to the drawings, the block forming mold 70 for manufacturing a cross-shaped block is provided with a main frame 71 and a hole forming bar 75.

The main frame 71 is formed so that the upper and lower portions thereof are opened but the internal space has a cross shape. The main frame 71 may be formed to be coupled to and separated from a plurality of members. Although not shown, in the case of the main block for the T-shaped block, it is only necessary that the internal space has a T-space corresponding to the T-shaped block.

In the main frame 71, holes 72 are formed in each side wall corresponding to the vertical portion of the block to be formed.

The hole forming bar 75 is formed to penetrate the hole 72 formed in the main frame 71.

A groove pillar protruding pillar member 73 is formed on the side wall of the main body 71 in a direction orthogonal to the side wall on which the hole 72 is formed.

Preferably, the protruding pillar member 73 is formed in a structure that can be detached from the main frame. As an example, a structure that may be detachable by screwing from the outside of the main body 71 to a part of the protruding pillar member 73 may be applied.

The block forming mold 70 is placed on the workbench (not shown) with the steel plate formed in the hole forming bar 75 in the inserted state, and curing by sequentially stacking the material for manufacturing described above inside the block forming mold 70 After curing, by removing the impact to the hole-forming bar 75 by removing it from the block molding frame 70 can be produced the block described above. In more detail, in the manufacture of a double-sided block attached to each side of natural stone, natural stone is properly disposed first, and then filled with sand to a predetermined height so that the natural stone is partially covered, and then the front layer 10a and the body layer 10b. ) Are formed sequentially. After that, the natural stone is disposed on the body layer 10b, and then the rear layer 10c may be formed. Alternatively, in the case of manufacturing a block by using a mortar in a dry method, the block molding frame 70 may be inverted, and then the natural stone 18 may be attached to the secondary.

In this case, it is preferable that an auxiliary member 80 is used to facilitate the attachment of the secondary natural stone.

Auxiliary member 80 is coupled to the bottom of the main body 71 is formed to be able to close the bottom, the upper surface is formed with a plurality of protrusions 81 for forming a natural stone seating groove. Of course, each of the protrusions 81 may be formed in the same or irregular shape.

Preferably, the auxiliary member 80 is formed detachably to the main body (71).

The detachable structure of the auxiliary member 80 with the main frame 71 may be coupled by a screw 85 as shown in the illustrated example, or alternatively by a coupling method (not shown). This can be applied.

When the block is manufactured by the dry method using the auxiliary member 80, the body layer 10b is formed of mortar in a state in which the auxiliary member 80 is coupled to the main body 71 as shown in FIG. The natural stone 18 is disposed on the body layer 10b and then the back layer 10c is formed of a material such as white mortar.

Subsequently, the auxiliary member 80 is dismantled from the main mold 71, and then sand is placed in the natural stone seating groove formed by the protrusion 81 of the auxiliary member 80 in the state in which the main mold 71 is turned over and seated on the work table. The natural stone 18 may be disposed after a predetermined depth, and the natural stone may be partially embedded with a mortar for forming the front layer 10a.

Finally, the hole forming bar 75 may be separated from the main mold 71, and then the blocks cured in the main mold 71 may be separated.

As described so far, according to the block with a stone according to the present invention and a block forming mold for manufacturing the same, the manufacturing is easy and the masonry strength can be increased by the interlocking engagement of the blocks with each other.
