Description

[0001] DECK FINISHER FOR CONCRETE [0002]

The present invention relates to a quick-speed concrete pavement equipment deck finishing machine,

More particularly, the present invention relates to a deck finishing machine for performing surface planarization of concrete when roads are packed using ultra fast speed concrete, and more particularly to a deck finishing machine for contacting a concrete to remove a surface step occurring during planarization of a concrete surface through a roller Speed concrete pavement equipment deck finer with a polish portion comprising a plurality of rotating poles.

Therefore, in the present invention, the surface flattening work of the concrete road is carried out through the rotation of the wing blade, so that when the road is paved, especially when the road is paved with a very fast curing speed than the ordinary concrete, The problem that the step is not removed due to curing can be solved.

Road paving technology is divided into asphalt pavement method and concrete pavement method.

Asphalt pavement and concrete pavement have advantages and disadvantages. Asphalt pavement is short in construction time and initial construction cost is high, but life span is short in 5 years and durability is weak compared to concrete, There is a drawback that the cost is high.

Concrete pavement is opposite to asphalt process and advantages and disadvantages. It is long durability, 20 years in service life because it is low maintenance cost and low initial construction cost. It takes a long time for concrete to cure, There are disadvantages.

In order to solve the problem of curing time which is a disadvantage of the conventional concrete pavement method, there is a method of using a quick-speed concrete in recent years.

The quick-speed concrete is a special concrete which solves the disadvantages of conventional concrete that should be cured for a long time and the curing time is reduced to 3 to 4 hours.

In the past, asphalt pavement roads accounted for a large share of asphalt pavement due to the low import cost of asphalt in combination with petroleum imports. However, nowadays, there are problems such as maintenance cost due to short maintenance, Roads are increasing trend.

The road paving method using such concrete will be briefly described as follows.

Planarization of concrete pavement is usually carried out by laying concrete to be laid to a certain thickness, vibrating operation to remove gas in concrete by applying vibration to the laid concrete, rolling work to flatten laid concrete, And a surface treatment operation for finely roughening the flattened concrete surface in order to secure a coefficient of friction and prevent noise are sequentially performed.

In this case, Korean Patent Laid-Open Publication No. 10-1995-0029501 (November 22, 1995) (hereafter referred to as Conventional Technology 1)

The above-mentioned prior art 1 has a supporting frame part composed of one side fixed angle and the other side fixing angle which support the whole from one side and the other side, and concrete which is pivotally installed on both side ends of the supporting frame part, And a drive unit fixed to the one fixed angle and driving the roller, and a method of constructing a concrete-laid surface using the same.

The above-mentioned prior art 1 is for rolling work during the flattening operation, and it is troublesome for the operator to directly work the above-mentioned other process by using other facilities. Therefore, the construction time is long, There is a problem that the quality is lowered.

As another conventional technique, there is Korean Patent Laid-Open No. 10-2009-0068877 (Jun. 29, 2009)

The conventional art 2 is a flat work machine for flattening the surface of a concrete, and a vibrator main body of a concrete vibrator is provided together with a main body having a roller for lateral movement, so that a flat work machine capable of simultaneously performing a vibration operation and a rolling operation .

In addition to the vibrating operation and the rolling operation, the above-described prior art 2 has a problem in that the operator must directly perform a planarizing operation using a separate facility.

As in the prior art 1 or the conventional art 2, the equipment for flattening the surface of the concrete pavement is generally called a deck finisher,

The conventional deck finishing is basically provided with a roller for flattening as described above, and a separate configuration for the above-mentioned operations is added or omitted at the front and rear ends of the rollers.

At this time, in the conventional deck finisher, the roller presses the upper portion of the concrete to flatten the concrete, and a step is formed between the roller and the section where the roller passed before due to both side ends of the roller.

If the step is not removed, the height of the surface of the road surface is changed at regular intervals on the road surface to ensure stable driving during driving, and ride comfort is also lowered. In addition, It is essential to remove the rear step.

Therefore, although not shown in the drawing, in order to remove the step, the conventional deck finishing machine is usually provided with a polishing machine for removing a step on the rear side of the roller with respect to the moving direction of the main body.

The abrasive machine is a plate-like member that presses downwardly while passing through a place where a step is formed to remove a step.

However, since the conventional technique is used in a general concrete pavement method, it is not difficult to remove a step in general concrete pavement,

As described above, when the road is packed using the quick-speed concrete, the curing of the concrete is very fast due to the characteristics of the material. Especially, the concrete in the stepped portion is formed in a state where a small amount protrudes from the surface of the concrete. There is a problem that the steps are hardened before the polishing operation after the work and are not removed by the conventional polishing machine.

Accordingly, the present invention has been made to solve the above-mentioned problems,

In order to easily remove the step even if curing is completed in a very early time when the step formed by the roller is completed and the road is packed by using the fast speed concrete, a plurality of suture wing rotating in contact with the surface of the concrete behind the roller Speed concrete pavement equipment deck finishing machine having a trimming section including a plurality of decks.

In addition, the present invention provides a fast-speed concrete pavement having an upward bending portion in front of the rotating direction of the blades so as to prevent the concrete surface from being broken or other stepped portions due to the forward end of the blades in the rotation direction of the blades, It is aimed to provide equipment deck finer.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described with reference to the accompanying drawings.

First, as shown in FIGS. 1 to 5, the fast speed concrete packing equipment deck finer according to the present invention

A main frame 10 disposed in a placement space S in which concrete is placed in a direction orthogonal to the longitudinal direction of the road and a concrete pivotally moved back and forth along the main frame 10, And a packaging unit 20 for carrying out a surface planarization operation in an organized manner.

As shown in FIGS. 1 and 2, a rail (R) provided along the longitudinal direction is installed on both sides of the packaging object (road; installation space), and the main frame 10 is provided with support frames 11).

As shown in FIG. 2, the support frame 11 is provided at its lower portion with a wheel portion 12 which can be moved by the rail R. As shown in FIG.

The main frame 10 has a guide function for reciprocating (lateral movement) of the packaging unit 20 and at the same time, the packaging unit 20 is supported and the packaging unit 20 is transported along the longitudinal direction of the road And has a function of a moving means.

The length of the main frame 10 can be varied according to the road standard and the length of the main frame 10 can be adjusted by a plurality of powders, Or a combination main frame 10.

The main frame 10 is provided with a power unit (not shown) to allow the front and rear wheels to be moved by operating the wheel unit 12, and a driver's seat (not shown) In the case of a small deck finer, the entire deck finishing machine can be operated by using a controller connected by wire or wirelessly.

3, the main frame 10 (see FIG. 2) is provided with guide rails 13 along its longitudinal direction to ensure lateral movement of the packaging unit 20,

The packaging unit 20 is provided on a main body 210 with a wheel 211 coupled to the guide rail 13 for lateral movement.

The guide rails 13 and the wheels 211 for realizing lateral movement of the packaging unit 20 are only examples of moving means and can be realized by various methods such as a belt moving method and a gear moving method.

1 and 3, the packaging unit 20 is connected to a main body 210 and a lower portion of the main body 210 and includes a screw 220 for a concrete package, a vibrator 230, a roller 240, a plucker 250, and a sweeping part 260.

The main body 210 reciprocates along the main frame 10 to move laterally as described above and further includes power means for driving the screw 220, the vibrator 230, the roller 240, (Not shown), and a control panel (not shown).

As shown in FIG. 3, a screw 220 is coupled to the forefront of the front frame 212 connected to the main body 210.

The screw 220 has a spiral wing 221 and is rotated forward to push the poured concrete forward in accordance with lateral movement of the main body 210, thereby adjusting the thickness of the concrete to be primarily flattened.

The number of the screws 220 is not limited. However, as shown in FIGS. 1 and 2, it is preferable that the screws 220 are formed in pairs in consideration of the size of the facility, ease of fabrication, and primary flattening efficiency.

3, a vibrator 230 is disposed behind the screw 220 in the front frame 212. As shown in FIG.

The vibrator 230 applies vibration to the thickness-adjusted concrete through the screw 220 to perform initial compaction, and discharges bubbles and the like in the concrete through vibration.

The vibrator 230 can be used in various ways for bubble removal during the conventional concrete construction,

And a track belt 231 installed in the transverse movement direction of the main body 210 for generating vibration together with the initial compaction operation.

The track belt 231 is provided with a plurality of protrusions 234 and concave portions 234 on the outer circumferential surface of the track belt 231 for vibration generation together with the initial compaction operation while the belt rotates when the main body 210 is transversely moved. (Refer to FIG. 6) is provided, so that the compaction operation is performed, and fine vibration is applied simultaneously with the rotation of the track belt.

An auxiliary frame 213 connected to the main body 210 is provided at the rear of the vibrator 230 and below the main body 210. The auxiliary frame 213 is provided with a roller 240. [

The rollers 240 are provided to rotate in the lateral direction of the main body 210 and have a width in a forward and backward direction and a width corresponding to the main body 210.

The roller 240 rotates during lateral movement of the main body 210 to pressurize the upper surface of the concrete to flatten the surface.

The number of the rollers 240 may be one or more, and the number of the rollers 240 is not limited.

On the other hand, a step D (see FIG. 1) in which the height of the surface of the concrete Co is varied occurs at a portion where both side ends 240A of the roller 240 pass during the planarization work by the roller 240. [

This is due to the viscosity of the concrete itself, and when the rolling operation is carried out with the concrete sticking to the end of the roller 240, a part of the concrete adhered to the end portion is adhered to the concrete surface,

In particular, when the ultra rapid concrete is used, it is necessary to remove the step due to the end of the roller 240 because the viscosity of the acrylic polymer series is increased due to the fast curing effect of the ultra fast speed concrete.

Particularly, when the main frame 10 moves forward in the case of the stepped portion by the front end of the roller 240, the stepped portion is flattened by the roller 240,

In the case of the stepped portion by the rear end of the roller 240, when the roller 240 is moved forward and then moved forward, the stepped portion formed thereon is not removed, which is an obstacle to the planarization of the concrete package.

Therefore, a rear frame 214 connected to the main body 210 is provided at the rear of the roller 240,

A trimming portion 250 for removing the stepped portion is provided under the rear frame 214.

In particular, when the concrete is used at high speed, it is difficult to remove the step when the initial curing is performed in a very short time due to the short curing time.

3 to 5, a plurality of pruning blades 253 rotating in contact with a concrete surface are introduced into the pruning section 250 to be vertically contacted with the pruning blades 253, So that the step is removed by pressurization in which the horizontal contact is made.

4 and 5, the polished portion 250 includes a first vertical frame 251 connected to the rear frame 214 (see FIG. 3) A body 252 coupled to rotate on the first vertical frame 251 and a plurality of pruning blades 253 radially provided on the body 252.

There is no limitation on the number of the impeller blades 253, but it is more preferable that the number of the impeller blades 253 is three or four.

The flat blade 253 is pressed while being repeatedly rotated while passing through the same section during lateral movement of the main body 210 to complete the flattening, and at the portion where the step is formed, the step can be removed through the blow by rotation In the case of packaging using ultra fast speed concrete in which curing takes place very quickly, the effect is very excellent.

Since the curved blade 253 is in the form of a plate and the concrete may be unintentionally pinched or cut due to the end of the curved blade 253 in the rotating direction at the time of rotation, (253A).

Because the upward bent portion 253A causes the connecting portion between the body of the oblique blade 253 and the upward bent portion 253A to have a gentle upward curve, the surface of the concrete is not damaged during rotation of the oblique blade 253, The step is pressed in the diagonal direction when the step portion is rotated, so that the step difference can be completely removed.

Although not shown in the drawing, the oblique blade 253 may be provided at both the oblique end and the forward bent portion.

Also, since the height of the flattened concrete surface can be changed according to the condition of the construction site, the polished portion 250 can adjust the height of the polished wing 253 of the polished portion 250 and the height of the concrete surface Means is further provided.

The height adjusting means may be implemented in various manners such as adjusting the height of the first vertical frame 251 itself or adjusting the height of only the vertical wing 253 coupled to the first vertical frame 251 However,

As shown in FIG. 3, a lift rod 254 connected to the first vertical frame 251 and screwed to the rear frame 214 is provided for easy fabrication and cost reduction of the deck fincher. And a handle 255 for moving up and down the upper arm 254.

During the initial planarizing operation of the roller 240 during the compaction operation using the deck finishing machine, the user may lift the scraper 250 up and move the scraper blade 253 in contact with the ground or other structure After doing so,

When the main frame 10 travels forward, the plaster 250 is lowered in accordance with the height of the flattened concrete surface, and the plucking blades 253 are rotated, and the plastering operation is performed according to the lateral movement of the main body 210 .

Needless to say, it is possible to provide not only a manual operation through the handle 255 but also a separate motor (not shown) in place of the handle to automatically adjust the height.

4 and 5, the polished portion 250 is further provided with a hydraulic cylinder 256 for absorbing vibration as the polished blade 253 rotates.

The hydraulic cylinder 256 is configured to absorb vertical vibration of the body 252 and the trimming blade 253 through hydraulic pressure,

5, a hydraulic cylinder 256 is provided below the first vertical frame 251, and a rotary shaft 252A connected to the body 252 for rotating the vertical wing 253 is connected to the cylinder 252. [ The hydraulic pressure is transmitted to the hydraulic cylinder so that the rotary shaft 252A connected to the body 252 of the vertical wing 253 is stably rotated, So as to absorb the vibration.

In addition, the hydraulic cylinder 256 and the vertical frame 251 may be twisted by the centrifugal force and the vibration due to the rotation of the impeller blade 253. As a reinforcing means for preventing the hydraulic cylinder 256 and the vertical frame 251,

A bearing 258 is provided under the hydraulic cylinder 256. The bearing 258 is coupled to the bracket 259 via a connecting rod 258A.

The bracket is mounted on the hydraulic cylinder 256 and fixed to the first vertical frame 251 so as to prevent twisting due to the centrifugal force of the brush blade 253 and to secure a stronger rigidity, And the lower brackets 259 and 259 'are coupled to each other through the connection rods 258A and 259A in a multi-layered structure, so that the rigidity of the support portion 258 can be more firmly ensured.

Next, the area where the planarization operation is finished through the roller 240 and the straight portion 250 starts to be hardened in a very smooth state. When the road surface is too smooth, the coefficient of friction of the vehicle with the wheel is decreased Thereby reducing the fuel consumption of the vehicle, and the noise caused by the driving of the vehicle is reflected as it is, thereby increasing the noise of the entire road.

In order to solve the above problem, as shown in FIG. 3, a sweeping part 260 connected to the rear frame 214 is further provided at the back of the sewing part 250.

The swash portion 260 includes a second vertical frame 261 connected to the rear frame 214, a hook frame 262 connected to a lower end of the second vertical frame 261, And a woven fabric (263) joined thereto.

The woven fabric 263 may be a nonwoven fabric having a coarse thickness, a cloth, a saddle, or the like. When the main body 210 is transversely moved, the roughness of the woven fabric 263 causes roughness of the surface of the concrete to increase Thereby increasing the coefficient of friction and allowing sound absorption.

Unlike the above-described construction, the swash-up portion 260 can be replaced with various members capable of finely increasing the roughness on the concrete surface.

Reference numerals 264 and 265 denote elevating rods and handles having the same configuration as the height adjusting means 254 provided in the trimming portion 250. [

As described above, when the road is packed using the ultra fast speed concrete, the concrete sticks to the screw 220, the vibrator 230, the roller 240, and the like due to the viscosity, .

Particularly, when the vibrator 230 is constituted by the track belt 231, when the ultra speed concrete is attached to the concave portion 233, vibration occurs together with the initial compaction operation through the protruding portion 234 and the concave portion 233 May be deteriorated.

6, in order to remove concrete adhered to the track belt 231, the elasticity of the elasticity of the elastic member 231 inserted into the recess 233 and contacting the outer circumferential surface of the track belt 231 Piece 238 is introduced.

The elastic piece 238 is provided inside the side frame 215 connected to one side of the front frame 212.

The elastic piece 238 is made of a material having a predetermined elastic force, and it is preferable that the elastic piece 238 is made of a special coating using a special synthetic resin or the like for preventing adhesion of the quick-speed light concrete.

Of course, a special coating may be applied to the outer circumferential surface of the orbiting belt 231 to prevent the adhesion of the quick-speed concrete. However, the coating surface is worn or corroded during long-term use, It is more effective in terms of equipment maintenance cost to replace or re-coat only the elastic pieces 238 rather than to replace or re-use them.

Therefore, it is preferable that the elastic piece 238 is detachably installed inside the side frame 215, and the end of the elastic piece is inserted into the recess 233.

The elastic piece 238 is swinged and displaced by the protrusion 234 as the orbiting belt 231 rotates due to the characteristic of the elastic material, Swing striking is performed on the outer circumferential surface, and the quick-speed concrete secured to the orbital belt is removed by vibration caused by contact with the outer circumferential surface or impact.

When the orbital belt 231 rotates in one direction, the protruding portion 234 and the concave portion 233 pierce the laid concrete 233 and the initial compaction operation is performed. When the orbital belt 231 is used for a long period of time, Speed concrete is adhered to the outer side surface of the concave portion 233, particularly, the concave portion 233, and when the time passes, hardening occurs in the concave portion and the function of the vibrator may be lost.

Accordingly, the present invention solves the above-mentioned problem by repeatedly swinging the protruding portion and the concave portion of the orbiting belt 231 by the elasticity of the elastic piece 238, thereby eliminating the quick-speed concrete fixed by contact and vibration .

Therefore, when the elastic piece 238 is positioned at the same height as the concave portion 233, as shown in [A] of FIG. 6, the elastic piece is restored, The concrete is firstly removed by the contact of the elastic pieces, and at the same time,

6B, the elastic piece 238 is bent in the direction opposite to the elasticity by the projection 234 in accordance with the rotation of the orbiting belt, Progress,

When the elastic piece comes to a position where the contact between the elastic piece and the protruding portion is disconnected, the elastic piece is swung back to its original position by elastic force and inserted into another rotating concave portion 233 to apply a blow to the outer peripheral surface of the orbiting belt 231, And then the third quick-release concrete is removed.

Although only the clockwise rotation of the orbital belt 231 is described in the figure,

As described above, the main body 210 reciprocates and moves along the main frame 10, so that the rotation direction of the orbiting belt 231 will also be continuously changed in the opposite direction,

It is obvious that the elastic piece 238 is displaced upward or downward swing according to the rotation of the orbiting belt 231,

Therefore, the desorption through the elastic piece 238 means that the recess 233 is randomly selected in accordance with the rotation of the orbiting belt 231, and the desorption is progressed repeatedly through contact and striking.

The elastic piece 238 may be provided at any position or any angle inside the side frame 215. It is further preferable that the elastic piece 238 is provided horizontally so that the same swinging displacement occurs in both directions of rotation as shown in the figure.

The deck finisher having the above-described structure performs the flattening operation while the main body 210 transversely moves at the initial position where the concrete is laid. When the main body 210 reaches either side of the main body 210, The lateral movement of the main body 210 is resumed after the main frame 10 moves forward by the set interval.

The concrete poured at the time of the lateral movement of the main body 210 is sequentially connected to the lower portion of the main body 210 to perform the respective operations according to the moving section of the main frame 10, The entire concrete road is finally cured due to the curing time for a predetermined time, thereby completing road pavement construction.

While the present invention has been described with reference to the accompanying drawings, it is to be understood that the present invention is not limited to the details of various modifications, , Changes and substitutions are to be construed as falling within the scope of protection of the present invention.
