Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a multi-layered water-permeable block molding apparatus having a reinforcing layer and a multi-layered water-

The present invention relates to a permeable block disposed on a road surface, and more particularly, to a multi-layered permeable block molding apparatus having a permeable layer and a reinforcing layer stacked thereon and having a reinforcing layer which is excellent in durability and long- Layered pitcher block.

Blocks used for roadway and walkway pavement provide the convenience of mobility of vehicles and pedestrians, and play a fundamental role in clearing the environment. There are various kinds of these blocks. Among them, the cement block is filled with cement and mortar, and then the pigment and pigment are put into a mold, followed by compression molding.

However, the cement block has a disadvantage in that the production cost is low and the surface strength is high, but the permeability is low. When the road surface is covered with an impervious layer, the groundwater becomes scarce, and when rain falls, the rainwater flows down to the river, causing natural disasters such as river flooding. This problem gets worse as urbanization progresses.

Accordingly, various attempts have been made to prevent the increase of surface runoff of surface water including rainwater and the like, and a permeable block having permeability has been developed and used in the field of press block. The water-permeable block is made to allow rainwater to permeate into the sidewalk and penetrate into the sidewalk block, and has innumerable voids therein.

These permeable blocks have conventionally been manufactured using cement and basic aggregate, and nowadays products with more various functions are being developed. For example, Korean Utility Model Registration No. 20-236949 discloses a sidewalk block having a plurality of perforation holes. The perforation hole of the sidewalk block is for smooth pitching.

However, the conventional water permeable block is focused only on the passage of rainwater, and most of the mechanical strength is insufficient. That is, it is easily damaged by the load of the vehicle or the pedestrian, so the life span is short and frequent maintenance is required.

Although various types of molding apparatuses for forming the water-permeable block have been used, most of the molding apparatuses have a limited production speed, and there is a limit in that a permeable block having a multi-layer structure can not be manufactured.

Hereinafter, one embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a cross-sectional view for explaining a lamination structure of a multilayer permeable block 10 having a reinforcing layer manufactured by the molding apparatus according to the first and second embodiments of the present invention.

As shown in the drawing, the multi-layer water permeable block 10 having a reinforcing layer has a laminated structure of a reinforcing layer 11, a center permeable layer 13, and an upper permeable layer 15. The reinforcing layer 11, the central permeable layer 13 and the upper permeable layer 15 have different porosity and characteristics.

The reinforcing layer (11) serves to improve the strength of the multi-layer permeable block (10) as a layer in contact with the surface to which the block is applied. For example, to prevent the permeable block 10 from being broken or broken by a load when a load is applied from the top of the multilayer permeable block 10. The density of the reinforcing layer 11 is larger than that of the central permeable layer 13 and the upper permeable layer 15, and the permeability thereof is almost zero.

The upper permeable layer 15 is a layer exposed to the upper part of the ground, for example, providing a flat walking surface that the pedestrian can step on. In particular, innumerable voids are formed in the upper water-permeable layer 15 to receive the rainwater and induce the lower part.

The central permeable layer 13 is a permeable layer sandwiched between the upper permeable layer 15 and the reinforcing layer 11 and has a porosity relatively higher than that of the upper permeable layer 15. [ The central permeable layer 13 receives the rainwater passing downward through the upper water permeable layer 15 and guides the rainwater to the ground surface (not shown). Part of the rainwater absorbed in the central permeable layer 13 may remain inside the void of the central permeable layer 13 because the lower portion of the central permeable layer 13 is the reinforcing layer 11. [

The interface between the reinforcing layer 11, the center permeable layer 13, and the upper permeable layer 15 is not planar, but the aggregates of the respective layers are entangled. Since the aggregate is mixed at the interface of each layer as described above, there is no fear of separation because of the interlayer bonding force. This lamination pattern is realized by a multi-layered waterproofing block molding apparatus 20 to be described later.

FIG. 2 is a structural view for explaining a configuration of a multi-layered waterproofing block molding apparatus having a reinforcing layer according to a first embodiment of the present invention.

As shown in the drawing, the multi-layered waterproofing block molding apparatus 20 according to the present embodiment includes first, second and third aggregate supplying units 30, 40 and 50, a press forming unit 60, an aggregate loading unit 70, A molding frame 74, and a chain conveyor 77. [ The molding apparatus 20 having such a structure has a structure for continuously producing the multilayer permeable block 10 having a reinforcing layer shown in Fig.

First, the first aggregate supply unit 30 has a supply hopper 31, an aggregate conveyor 32, and a metering hopper 33. The first aggregate supplying unit 30 may serve to supply the aggregate for the reinforcing layer 11 (hereinafter, the first aggregate).

The supply hopper 31 receives the first aggregate supplied from the outside and puts it down on the aggregate conveyor 32. The aggregate conveyor 32 horizontally moves the first aggregate supplied from the feed hopper 31 and guides it to the quantitative hopper 33.

The metering hopper 33 receives the first aggregate supplied through the aggregate conveyor 32 and injects the metered amount into the conveying case 72 waiting in the vertical lower portion thereof. A shutter 33a is provided at the lower end of the metering hopper 33 for this purpose. The shutter 33a is opened / closed by the shutter driving portion 33b and keeps the amount of the first aggregate to fall down to a constant level.

The second aggregate supply unit 40 supplies the aggregate (hereinafter referred to as second aggregate) constituting the central permeable layer 13 and includes a supply hopper 41, an aggregate conveyor 42, a metering hopper 43 . The supply hopper 41 receives the second aggregate supplied from the outside and guides it to the lower portion. The aggregate conveyor 42 discharges the second aggregate, which is disposed very close to the lower end of the supply hopper 41 and accommodated in the supply hopper 41, in the right direction in the figure. The second aggregate flows in the right direction by the action of the aggregate conveyor 42, hits the cover 41a, and enters the quantitative hopper 43. [

A shutter 43a is provided at the lower end of the metering hopper 43. [ The shutter 43a determines the amount of the second aggregate that is opened and closed by the shutter driving unit 43b and falls downward. It is a matter of course that the transport case 72 must be in a standby position before the second aggregate is discharged from the quantitative hopper 43 in the vertical lower part of the fixed amount hopper 43. [ The position of the carrying case 72 is controlled by a loading actuator 71, which will be described later.

The third aggregate supplying unit 50 has the same structure as the first aggregate supplying unit 30 and is installed on the opposite side of the second aggregate supplying unit 40 with the press forming unit 60 interposed therebetween. The third aggregate supplying unit 50 is for supplying the aggregate constituting the upper water permeable layer 15 (hereinafter referred to as a third aggregate) and includes a feed hopper 51, an aggregate conveyor 52, and a metering hopper 53.

The feed hopper 51 receives the third aggregate from the outside and moves it to the aggregate conveyor 52. The aggregate conveyor 52 horizontally moves the third aggregate and puts it into the quantitative hopper 53. [ A shutter 53a is provided at the lower end of the metering hopper 53. [ The shutter 53a opens and closes by the shutter driving unit 53b and regulates the amount of discharged third aggregate. It is a matter of course that the conveying case 72 should be standing on the vertical lower portion of the quantitative hopper 53 before the third aggregate drops from the quantitative hopper 53.

In this embodiment, two of the carrying cases 72 are provided. The left case 72 in the drawing interlocks with the first and second aggregate supplying parts 30 and 40 and the right carrying case 72 interlocks with the third supplying part 50.

The press-formed portion 60 is provided on a vertical upper portion of a forming mold 74 to be described later. As shown in Fig. 5D, the press forming portion 60 is formed in the molding space 74b of the molding mold 74, (A) is completed and the aggregate (A) is pressed to obtain a molded product. The obtained molded product is, of course, the multi-layered waterproofing block 10.

The press forming portion 60 includes a hydraulic press 62 fixed to the frame 61 and a pressing head portion 63 fixed to the lower end of the ram 62b of the hydraulic press 62. The ram 62b is a piston rod that ascends and descends in the vertical direction when the hydraulic press is operated.

A plurality of pressure plates 63a are provided at the lower end of the pressure head portion 63. [ The pressure plate 63a is a rectangular plate having a predetermined thickness and width and enters downward into the mold frame 74 to press the aggregate. It goes without saying that the width of the pressure plate 63a corresponds to the width of the molding space 74b.

On the other hand, a mold frame 74 is fixed to a vertical lower portion of the press-formed portion 60. The forming mold 74 is held horizontally while being fixed between the both side horizontal bands 73a and 73b. Further, a grid-shaped partition wall 74a is built in the inside of the forming mold 74. The partition wall 74a serves to provide a plurality of molding spaces 74b in the mold frame 74. [ The molding space 74b is open to the bottom as well as the bottom.

The reason for opening the upper portion of the molding space 74b is to receive the aggregate and the reason for opening the lower portion is to pull the molded article, that is, the water permeable block 10 in the direction of the arrow z, as shown in Fig. 5E .

A base table 75 is horizontally installed on the lower portion of the mold frame 74. The support table 75 is a plate-shaped member that moves up and down with being supported by the lift actuator 76. The forming table 74 is fixed to the horizontal tables 73a and 73b so that when the lower table 75 is lowered, the lower table 75 is separated from the forming table 74. [ If the molded article is contained in the mold 74, the molded article falls from the mold 74 to the bottom.

When the support table 75 is raised, the support table 75 is brought into close contact with the bottom surface of the molding frame 74, blocking the lower part of the molding space 74b so that the inserted aggregate does not come off.

A chain conveyor 77 is installed on both sides of the support table 75. The chain conveyor 77 is a conveying means for conveying the plurality of conveying plates 78 in the horizontal direction. The conveying plate 78 is a rectangular plate having a predetermined thickness and is conveyed along a predetermined path while being put on the chain conveyor 77.

Particularly, the conveying plate 78 passes through the upper portion of the lowered table 75 during conveyance. That is to say, in a state in which the base table 75 is located at the bottom dead center, the transfer plate 78, which has been moved on the left chain conveyor 77 in the figure, rises to the top of the base table 75. Even if the leading end of the conveying plate 78 in the conveying direction enters the upper portion of the supporting table 75, the trailing end of the conveying plate 78 can continuously receive the conveying force from the chain conveyor 77.

The conveying plate 78, which has been raised in advance on the support table 75, is pulled out in the rightward direction in the conveying direction front end portion in contact with the chain conveyor 77 on the right side in the figure.

It is needless to say that the upper surface of the support table 75 located at the bottom dead center should be located at the same height as the conveying surface of the chain conveyor 77 so that the above process can be performed.

Horizontal bars 73a and 73b are provided on the upper portion of the chain conveyor 77. The horizontal bands 73a and 73b are arranged in a straight line with the forming mold 74 interposed therebetween. A sliding surface 73c is provided on the upper surface of each of the horizontal tables 73a and 73b. The sliding surface 73c guides the linear movement of the carrying case 72. [

Quantitative hoppers 33 and 43 are positioned vertically above the sliding surface 73c of the left horizontal table 73a and other quantitative hoppers 53 are positioned vertically above the right horizontal table 73b. As a result, the carrying case 72 can be positioned in the vertical lower part of the quantitative hoppers 33, 43 and 53 while being supported by the sliding surface 73c.

An aggregate loading unit 70 is installed on each of the horizontal bases 73a and 73b. The aggregate loading section 70 serves to receive the aggregate dropped from the quantitative hoppers 33, 43 and 53 and to supply the aggregate to the forming mold 74. The aggregate loading unit 70 includes a loading actuator 71 and a carrying case 72.

The loading actuator 71 has a cylinder 71a and a piston rod 71b and makes the carrying case 72 reciprocate. The carrying case 72 slides forward and backward by the loading actuator 71. The maximum forward conveying point of the conveying case 72 is the vertical upper portion of the forming die 74 and the maximum retreat point is the vertical lower portion of the quantitative hoppers 33 and 53. The detailed configuration of the carrying case 72 is shown in Figs. 3 and 4. Fig.

Figs. 3 and 4 are views for explaining the structure of the carrying case 72 shown in Fig.

As shown in the figure, the carrying case 72 includes a case body 72a fixed to an end of a piston rod 71b of a loading actuator, a sliding plate 72d slidably supported in the case body 72a, And a side actuator 72e fixed to the outer wall of the case body 72a. A pair of stirring parts 72r provided inside the case body 72a, and a motor 72g.

The case body 72a takes the form of a rectangular frame and has an internal space 72b that is opened up and down. The inner space 72b is a cavity in which the first, second and third aggregates are successively contained.

A guide groove 72c is formed in the inner wall surface of the case body 72a. Although the figure shows that the guide grooves 72c are formed only on one inner wall surface, the guide grooves 72c are arranged on the inward facing surfaces facing each other in parallel and opposed to each other.

In addition, in the case body 72a, a through opening slit 72u having a predetermined width is provided at a lower end of a surface on which the piston rod 71b is fixed. The opening slit 72u is a horizontally extending through-hole and allows the sliding plate 72d to pass therethrough. The sliding plate 72d passes through the opening slit 72u and is supported by the guide grooves 72c at both ends in the width direction thereof.

Reference numeral 72q denotes a shaft hole. The shaft hole 72q is a hole in which the shaft 72s of the agitating portion 72r is fitted while being fitted. The shaft 72s is rotatable by the motor 72g while being supported by the shaft hole 72q.

The sliding plate 72d is a plate-shaped member having a predetermined width and thickness and is slidable in the direction of arrow d or in the opposite direction with both end portions in the width direction being supported by the guide groove 72c. The sliding plate 72d blocks the lower portion of the case body 72a while being completely inserted into the inner space 72b. For example, the aggregate introduced into the inner space 72b is supported so as not to fall downward. When the sliding plate 72d is drawn out in the direction of the arrow d, the lower part of the case body 72a is opened and the aggregate drops down.

The side actuator 72e has a cylinder 72v and a piston rod 72w and is fixed horizontally to the outer wall surface of one side of the case body 72a. A connector 72f is fixed to the end of the piston rod 72w of the side actuator 72e.

The connector 72f is a member for connecting the piston rod 72w and the sliding plate 72d and transmits the power of the side actuator 72e to the sliding plate 72d so that the sliding plate 72d contacts the side surface of the case body 72a Thereby opening and closing the lower portion.

On the other hand, the stirring portion 72r has a shaft 72s which is rotatably fitted in the shaft hole 72q and a plurality of stirring blades 72t fixed to the outer peripheral surface of the shaft 72s. Particularly, one end of the shaft 72s extends to the outside of the case body 72a and has sprockets 72m, 72k and 72n at its extended ends.

Reference numeral 72g denotes a motor. The motor 72g is for driving the stirring portion 72r and transmits power to the stirring portion 72r through the chain 72p as shown in Fig.

Referring to Fig. 4, a motor 72g is fixed to one side of the outer surface of the case body 72a, and a drive sprocket 72h is mounted on a drive shaft of the motor 72g. The first and second driven sprockets 72k and 72m are fixed to the shaft 72s of one of the two agitating parts 72r and the third driven sprocket 72n is mounted to the other shaft.

The drive sprocket 72h and the first driven sprocket 72k, the second driven sprocket 72m and the third driven sprocket 73n are connected through a chain 72p. As a result, the rotational force output by the operation of the motor 72g is transmitted to the both-side agitating portion 72r through the chain, and agitates the agitating material charged into the case main body 72a.

5A to 5E are views for explaining the operating principle of the carrying case 72 shown in Fig. For convenience of explanation, a description will be made with reference to a carrying case 72 installed on the left side of FIG.

5A and 5B, when the first aggregate is inserted into the carrying case 72 waiting on the one horizontal base 73a, the loading actuator 71 operates to move the carrying case 72, In the direction of arrow a. The carrying case 72 is located in the vertical upper portion of the forming mold 74 waiting. At this time, since the sliding plate 72d is closed, the aggregate does not spill downward.

When the conveying case 72 is correctly positioned on the vertical upper portion of the mold frame 74, the stirring portion 72r is operated to stir the first aggregate and at the same time, the sliding plate 72d is rotated by the side actuator 72e Move in the direction of arrow b. As the sliding plate 72d moves in the direction of arrow b, the first aggregate falls downward and fills the interior of the mold frame 74. It goes without saying that the lower part of the forming mold 74 is blocked by the transfer plate 78 at this time.

When the introduction of the first aggregate is completed, the empty carrying case 72 is moved in the direction of the arrow c in FIG. 5D to move to the vertical lower portion of the quantitative hopper 43, and then the second aggregate is supplied. If the second aggregate is filled in the case body 72a, the above operation is repeated to supply the second aggregate into the forming mold 74. [ Since the first aggregate has already been injected into the molding space 74b, the second aggregate covers the upper portion of the first aggregate.

Subsequently, the conveying case 72 is moved to the vertical upper portion of the forming die 74 in a state in which the third aggregate is filled in the carrying case 72 standing on the opposite side horizontal base 73b, Put it on top of aggregate.

If all of the first, second, and third aggregates have been put into the mold 74 through the above process, the pressure head 63 is lowered to urge the aggregate downward with the pressure plate 63a. The aggregate is made of the multi-layer watertight block 10 shown in Fig. 1 as it is squeezed under high pressure inside the mold 74. The method of pressing the aggregate to form a block of a desired shape takes the conventional method.

When the molding is completed, the pressing head portion 63 is raised and the support table 75 is lowered. As the support table 75 descends, the multi-layer waterproofing block 10 inside the molding space 74b falls in the direction of the arrow z.

When the support table 75 reaches the bottom dead center, the conveying plate 78 is pulled out in the direction of the arrow k by the chain conveyor 77 and conveyed along the remaining conveying path. At this time, it is a matter of course that the multi-layer water-permeable block 10 is mounted on the transfer plate 78.

FIG. 6 is a plan view schematically showing another example of a multi-layered waterproofing block molding apparatus having a reinforcing layer according to a second embodiment of the present invention, and FIGS. 7 and 8 are views for explaining the operation of the molding apparatus shown in FIG. 6 Side view.

Hereinafter, the same reference numerals as those of the above-mentioned reference numerals denote the same members having the same function, and repetitive description thereof will be omitted.

As shown in the figure, the multi-layered waterproofing block molding apparatus 20 according to the second embodiment includes a turntable 81, a rotation motor 83, a plurality of molds 74, first, 40, and 50, a press-formed portion 60, a mold support plate 85, a support table 75, a lifting actuator 76, and a discharge portion. In addition, the discharge section includes a horizontal discharge actuator 87 and a pushing body 88.

First, the turntable 81 is a disk-like member which is horizontally held with respect to the paper surface and rotates stepwise by 90 degrees by a rotation motor 83, and has four forming molds 74 at the edges thereof. Four molds 74 are arranged at an angle of 90 degrees with respect to the rotational axis of the rotary motor 83. [ The respective shaping molds 74 are moved in the direction of the rotation of the turntable 81 so that the quantitative hoppers 33, 43 and 53 of the first, second and third aggregate supply sections 30, After stopping at the lower part of the vertical, it rotates by 90 degrees and then rotates by 90 degrees.

While the shaping mold 74 is stopped at the vertical lower portion of the quantitative hoppers 33, 43 and 53, the first, second, and third aggregates are put in, and the press molding section is operated to compress the aggregate.

The casting mold supporting plate 85 is a plate-shaped member horizontally fixed to the lower portion of the turntable 81 and supports the lower part of the casting mold 74 to block the aggregate inside the molding mold from falling downward. The lower end of the forming mold 74 always abuts against the upper surface of the forming mold supporting plate 85 and slides.

The support table 75 is a member positioned so as to be able to move up and down on the vertical lower portion of the press-formed portion 60, and has the above-described elevating actuator 76 at the lower portion thereof. Needless to say, the lifting and lowering operation is performed by the operation of the lifting actuator 76.

Normally, the support table 75 maintains the same height as the casting mold supporting plate 85 in a raised state and supports the casting mold when the casting mold 74 reaches the lower portion of the press forming portion 60. In addition, the same height is maintained while the pressing head portion 63 is lowered and presses the aggregate.

After the press forming of the aggregate is completed, the support table 75 is lowered in the z direction in FIG. 8 by the action of the elevating actuator 76, so that the molded product, that is, .

On the other hand, the discharge actuator 87 is mounted horizontally on the bottom surface of the mold support plate 85 and has a pushing body 88 at the end of the piston rod 87a. The pushing body 88 is moved in the radial direction of the turntable 81 in accordance with the operation of the ejecting actuator 87 and the multi-layer watertight block 10 supported on the base table 75 in the lowered state is conveyed to the chain conveyor 77 on the transfer plate 78. Thus, the molding apparatus according to the second embodiment performs the operation of molding the multi-layer water-permeable block 10 while the turntable 81 rotates stepwise.
