A preferred embodiment of the apparatus for manufacturing a sidewalk block according to the present invention will be described with reference to the drawings, and a plurality of such embodiments may exist, and the object, features and advantages of the present invention will be better understood through these embodiments be able to

1 is a schematic plan view showing an apparatus for manufacturing a sidewalk block according to the present invention, and FIG. 2 is a partial schematic side view showing an apparatus for manufacturing a sidewalk block according to the present invention.

As shown in FIGS. 1 and 2, the apparatus for manufacturing a sidewalk block according to the present invention provides a dry mortar supply unit 100 according to the step-by-step rotation of the center motor M between the upper body B1 and the under body B2. , the dry compaction unit 200, the wet mortar supply unit 300, the mortar crimping unit 600 and the lower mold 80 for completing the sidewalk block 90 while sequentially positioned toward the sidewalk block demolding unit 700, respectively. and a turntable T radially having the mold hole T1 accommodated therein.

That is, according to the step-by-step rotation of the center motor M between the upper body B1 and the under body B2, the turntable T moves the dry mortar supply unit 100, the dry compaction unit 200, and the wet mortar supply unit ( 300), the mortar crimping unit 600, and the sidewalk block demolding unit 700 are sequentially rotated so that the lower mold 80 can be positioned in place, respectively.

Specifically, when the lower mold 80 is placed in the dry mortar supply unit 100, it is composed of, for example, small particles of gravel, sand and cement containing a small amount of moisture (composition and composition ratio are general matters, so the detailed description is After the dry mortar 91 is filled in the lower mold 80, it is moved to the dry compactor 200 and compacted, and again, when the lower mold 80 is placed in the wet mortar supply part 300, for example, For example, it is composed of stone powder, sand and cement containing sufficient water (composition and composition ratio are general matters, so detailed description is omitted), and at the same time, a wet mortar 92 in a dough state with a color is filled on the dry mortar 91, and then The wet mortar 92 is pressed in the mortar crimping unit 600 to allow moisture to penetrate into the dry mortar 91 and to be dehydrated at the same time to provide the sidewalk block 90 that is firmly pressed against each other, and then the sidewalk block demolding unit By demolding through (700) to be dried and cured in a drying room and curing room in the United States, it is possible to complete the firmly reinforced sidewalk block (90).

3A is a front sectional view showing a lower mold 80 applied to the device for manufacturing a sidewalk block according to the present invention, and FIG. 3B is a flow from the lower mold 81 among the lower molds 80 applied to the device for manufacturing a sidewalk according to the present invention. It is a front cross-sectional view showing a state in which the base 83 is spaced apart.

The lower mold 80 applied to the device for manufacturing a sidewalk block according to the present invention has a lower opening portion 81a as shown in FIGS. 90d) The lower formwork 81 that determines the shape of [see Figs. 4a to 4c] and the spaced apart means 82 from the lower end of the lower formwork 81 while having an inner through hole 83a The flow base 83 covering the lower opening 81a, the pins 84 upright on the flow base 83, and the pins 84 are seated on the flow base 83 in the lower formwork 81 and It includes a lower mold exclusive plate 85 that determines the shape of the bottom surface 90b of the sidewalk block 90 while having the lower pinholes 85a through it.

For example, the lower formwork 81 has a structure that determines the shape of the left and right side surfaces 90c and front and rear side surfaces 90d of the sidewalk block 90, such as a square, rectangle, polygon, or oval, of the turntable T. It may be mounted in the mold holes T1, and the flow base 83 covers the lower opening 81a so as to be spaced apart from the lower end of the lower mold 81 by the spacer 82.

At this time, the flow base 83 is usually in contact with the lower end of the lower formwork 81 and tightly covers the lower opening portion 81a, but the force that physically descends to the flow base 83 [descending by foreign substances to be described later] force] is applied, it takes a structure that can be spaced apart from the lower end of the lower frame 81 by the spacing means 82 as shown in FIG. 3B (arrow), and the internal through-hole 83a is formed in FIGS. 8A to 8A to be described later In the mortar crimping unit 600 shown in FIG. 8c , the crimping bundle 61e of the crimping hydraulic means 61 passes to push up the lower mold exclusive plate 85 and the reinforcing plate 86 .

More specifically, the spacing means 82 is sequentially drilled toward the screw groove 82a drilled in the lower end of the lower formwork 81, and the screw groove 82a of the lower formwork 81 from the edge of the floating base 83. The donut-shaped stepped 82d provided by the true optical hole 82b and the narrow hole 82c, the extension spring 82e fitted into the optical hole 82b to be supported by the donut-shaped stepped 82d, and the extension spring 82e It includes a spaced bolt (82f) fastened to the screw groove (82a) of the lower formwork (81) via the narrow hole (82c) while pressing with the donut-shaped step (82d).

While pressing the extension spring 82e fitted in the optical hole 82b with the donut-shaped step 82d, the spacing bolt 82f is fastened to the screw groove 82a via the narrow hole 82c, so that the normal spacing bolt 82f As shown in Fig. 3a by the action and reaction of the supported extension spring 82e, the flow base 83 can be brought into close contact with the lower end of the lower formwork 81 to closely cover the lower opening portion 81a. , when a physically descending force is applied to the flow base 83, as shown in FIG. 3b, the donut-shaped step 82d contracts the extension spring 82e from the lower end of the lower frame 81. can be separated.

On the other hand, the lower mold 80 applied to the device for manufacturing a sidewalk block according to the present invention is interposed between the floating base 83 and the lower mold exclusive plate 85 and has reinforcing pinholes 86a through which the pins 84 pass. The plate 86 may be further included, and further, it may further include liners 87 detachably fixed to the inside of the lower formwork 81 relatively higher than the height of the lower formwork 81 .

When the dry mortar 91 and the wet mortar 92 filled in the lower mold 80 are continuously compressed in the mortar crimping part 600, the phenomenon that the lower mold exclusive plate 85 is deformed by the pressing pressure is prevented by the reinforcing plate ( 86) to ensure lifespan, and furthermore, when the upper mold 62 is in direct contact with the lower mold 80 when the dry mortar 91 and the wet mortar supply part 300 are compressed, the lower mold 80 is deformed. Because the replacement cost increases, the liner 87 (liner 87 made of heat-treated alloy), which is not easily deformed, can be detached from the inside of the lower formwork 81 relatively higher than the height of the lower formwork 81. fixed to ensure longevity.

Preferably, the liners 87 are fitted into the fixing grooves 83c formed along the edges of the flow base 83 .

When the liners 87 are fitted into the fixing grooves 83c formed along the edges of the floating base 83, when a force to physically descend on the floating base 83 is applied, the liners 87 fitted into the fixing grooves 83c are To prevent leakage of the dry mortar 91 (when the flow base 83 simply covers the lower opening 81a of the lower formwork 81) Even if the dry mortar 91 not only escapes into the gap between them, but also the flow base 83 rises again, it is impossible to prevent the continuous separation of the dry mortar 91 by foreign substances caught in the gap between them] .

And, the pin 84 is screwed to the screw hole 83d drilled in the floating base 83 so that the vertical height can be adjusted.

The sidewalk block 90 may have a different height depending on the construction environment. Accordingly, when the vertical drain hole 97 to be described later is formed, the pin 84 is inserted into the screw hole 83d drilled in the floating base 83 according to the height. ) is screwed so that the vertical height can be adjusted so that the sidewalk block 90 of various sizes can be manufactured more effectively.

4A is a perspective view showing a sidewalk block 90 prepared by applying a lower mold 80 applied to the device for manufacturing a sidewalk block according to the present invention, and FIG. 4B is a lower mold 80 applied to the device for manufacturing a sidewalk according to the present invention. It is a plan view and a front cross-sectional view showing the sidewalk block 90 prepared by applying At this time, non-explanatory reference numeral 93 denotes a liquid pigment 93, 94 denotes a powder paint 94, and a two-tone color by a liquid pigment 93 together with a wet mortar 92 in a kneaded state having a color of One Tone Color. Of course, it is possible to make the appearance more beautiful by directing the splendor of the Three Tone Color of the powder paint (94) on the surface of the .

In the lower mold 80 applied to the device for manufacturing a press block according to the present invention, the pin 84 is fixed to the flow base 83 at the same height as the height of the liner 87 .

A typical sidewalk block 90 forms a vertical half drain hole 95 at the edge to provide a drainage path, and is merged with the vertical half drain hole 95 of the adjacent sidewalk block 90 to form a combined drain hole 96. It consists of a structure that completes the

The vertical half drain hole 95 at the edge of the sidewalk block 90 can be easily formed, for example, by embossing the liner 87, but the vertical drain hole 97 in the sidewalk block 90 is formed between the pin 84 and the upper part. It can be completed only by the matching of the mold 62. In this case, even if there is a fine foreign material on the pin 84, the pin 84 is caused by the pressure facing each other between the lower mold 80 and the upper mold 62. There are always cases where it is easily broken and the vertical drain hole 97 cannot be completed.

In the present invention, in a state in which the pin 84 is fixed to the flow base 83 at the same height as the height of the liner 87, a foreign substance is caught on the pin 84, so even if a force is applied to the flow base 83 to descend, the pin ( By separating the flow base 83 from the lower end of the lower frame 81 by the separation means 82 before the 84 is broken, the pin 84 can be protected, thereby fundamentally preventing the pin 84 from breaking. that made it possible to remove it.

Furthermore, it is preferable to further include a tower drainage conduit 99 connected to the vertical drainage hole 97 along the top surface 90a to realize rapid drainage in case of rain.
