Description

Device for Fixing and Inducing Wire

More particularly, the present invention relates to a reinforcing bar guiding unit for reinforcing bars to be placed within an allowable tolerance, and a reinforcing bar for guiding the concrete in a state in which the reinforcing bar is disposed within a tolerance range from the rear of the reinforcing bar guiding portion. And a hopper portion spatially spatially concomitantly inserted into the hopper portion.

Cement concrete pavement is a type of packaging that maintains structural stability by reducing the stress caused by the load to less than the bearing capacity of the lower layer by resisting shear or warping caused by traffic load of cement concrete slab.

The cement concrete pavement is generally classified into three types according to the reinforcement reinforcement and joint spacing: non-jointed concrete pavement (JPCP), joint reinforced concrete pavement (JRCP), and continuous reinforced concrete pavement (CRCP).

The JPCP does not have any reinforcement reinforcement, and the occurrence of cracks is artificially controlled by a joint having a certain interval. It is necessary to construct the joint at a proper depth to cause a crack Can be prevented.

However, since the JPCP has a tendency to deteriorate ride quality due to breakage of the joint portion (step, rupture crack, pumping, etc.) over time, a certain amount of longitudinal reinforcement is placed in the center of the cement concrete slab And this method is a jointed reinforced concrete pavement (JRCP).

The longitudinal reinforcing bars of the Jointed Reinforced Concrete Pavement (JRCP) play a role in restricting excessive cracking caused by the tensile force of the lower portion of the slab. Therefore, although the gap between joints is longer than that of non - jointed concrete pavement, there are still problems that structural damage occurs in the line of eye and transverse cracks.

On the other hand, the continuous reinforced concrete pavement (CRCP) is a type of package in which the longitudinal joints are completely removed by installing more longitudinal reinforcing bars than reinforced concrete. Continuous reinforced concrete pavement is good because it has no joints and it has better ride quality than other types of pavement even under heavy traffic volume.

However, in the conventional continuous reinforced concrete pavement, it is general that the concrete is poured into the reinforced bars to which the reinforced concrete is laid. Therefore, as shown in FIG. 1, it is necessary to provide a transverse auxiliary reinforcing bar for supporting the longitudinal reinforcing bar to be positioned at a predetermined position and a support for supporting the transverse reinforcing bar before the concrete is poured, There is a problem that the manual operation is inevitable and the manpower consumption is large and the overall construction speed is slowed down.

In addition, concrete can not be supplied from the side of the packing when the concrete is poured, and it is difficult to construct concrete pavement, tunnel entrance, bridge connection, lane separation, etc. in a tunnel with a very narrow working space. It was difficult to apply to the environment.

In addition, in the conventional continuous reinforced concrete pavement (CRCP), longitudinal reinforcing bars are connected in a folded manner, so that not only a lot of labor is required for working the reinforcing bars, but also the reinforcing bars and concrete are not attached well at the folded portions, There was a problem.

Meanwhile, Japanese Unexamined Patent Publication No. 4036999 discloses a prior art document for solving the above-mentioned problems, including an arrangement method for building a pavement structure, a method of supplying a pavement material, and a material supply device having the device and a pavement function (2007. 11.

In the prior art document 1, as shown in FIG. 2, longitudinal reinforcing bars are arranged side by side so as to provide a space through which the feeder can move, and a support moving means for moving the longitudinal reinforcing bars in a supported state is disclosed However, since the reinforcing bars and concrete were not simultaneously spatially placed, the longitudinal reinforcing bars had to be lowered. Therefore, there has been an inefficiency that a process of tying the longitudinal reinforcing bars and the transverse reinforcing bars together and having a chair at the bottom thereof necessarily has to be accompanied.

Also, the prior art document 2 has a limitation in adjusting the height in the vertical direction according to the condition of the construction site, and it is difficult to flexibly adjust the amount of concrete to be poured, and it is difficult to uniformly install the concrete.

Furthermore, since the above-mentioned prior art documents are operated separately from each other, at least three operators are required to operate the apparatus, and there have been considerable restrictions on the transportation of each apparatus.

Also, after the daily unit process is finished, there is a need to cut the reinforcing bars after moving the equipment to cure the concrete, or to prepare a separate mold.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a reinforcing bar guide fixing device (D) according to the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 2, when the reinforcing roots and the concrete are not simultaneously spatially and temporally placed, the reinforcing rods and the material supplying device for constructing the pavement structure of the prior art document 1, There is a problem that the concrete is poured in a state where it is hung downward.

Therefore, as in the prior art of FIG. 1, there has been an inefficiency that a process of arranging longitudinal reinforcing bars and arranging the lateral reinforcing bars and connecting the longitudinal reinforcing bars and providing a chair below the reinforcing bars must necessarily be inevitably accompanied.

In addition, Prior Art Document 2 discloses only a technical idea to prevent the reinforcing bar from being stuck to the lower portion by applying a tensile force to the reinforcing bars without considering the simultaneity of the reinforcing bars and the pouring of the concrete.

As shown in the perspective view of FIG. 3, the reinforcing bar guide fixing device D of the present invention includes a reinforcing bar guiding part 100 for reinforcing bars to be spaced apart from each other along the longitudinal direction of the road, And a hopper unit 200 which is located behind the reinforcing bars 100 and 100 and places the reinforcing bars within the allowable tolerances.

In this case, the allowable tolerance may vary depending on the width and thickness of the concrete pavement to be laid. However, the tolerance in the present invention is defined as the allowable tolerance within the range of ± 15 mm , And a range within ± 25 mm to the left and right.

Also, the position before the concrete is poured and the position before poured are defined as relative 'forward' and the opposite direction is defined as 'rearward'.

The 'simultaneous' of the present invention means that a specific portion of the reinforcing bar exposed rearward through the reinforcing bar guide portion 100 is positioned in the allowable tolerance in a state where it is not supported by the supporting means such as a spacer or a transverse reinforcing bar And the concrete is poured by the hopper part 200.

That is, the reinforcing bars 100 induce the longitudinal reinforcing bars and are fixed within the allowable tolerances, which is a predetermined horizontal and vertical phase position. As a result, the conventional lateral reinforcing bars and supports for supporting them are unnecessary, The construction speed can be improved.

That is, as shown in FIG. 5, the reinforcing bars are automatically and continuously laid, and the concrete C is simultaneously placed in the hopper portion 200 at the same time, and the reinforcing bars are placed spatially within the allowable tolerance, (C) to be laid, it does not require a separate auxiliary reinforcing bars and supports.

In this case, it is possible to reduce the amount of reinforcing bar and labor required for folding, since it is not necessary to fold the longitudinal reinforcing bars by using reinforcing bars to continuously guide the reinforcing bars, Can be minimized. The reinforcing joint means may be a coupler or the like.

The use of the above-described reinforcing bar connecting means can stably provide continuity and supply the reinforcing rods to the reinforcing bar guide portion 100, thereby shortening the entire construction period and minimizing the amount of reinforcing bar and workload, It is possible to minimize the occurrence of breakage at the site.

As shown in FIG. 7, a plurality of guide tubes 110 arranged in a transverse direction may be provided in the tube frame 120 in the reinforcement guide part 100.

The reinforcing bars 100 may be formed in any shape as long as the reinforcing bars are spaced apart from each other along the longitudinal direction of the road so as to be arranged within the allowable tolerance. However, the reinforcing bars may be formed of a plurality of guide tubes 110 arranged in the transverse direction .

That is, the guide tube 110 has a shape of a hollow tube, through which the longitudinal reinforcing bars are guided, and at the same time, the reinforcing bars are fixed within a tolerance of a predetermined horizontal and vertical position.

In addition, as shown in FIG. 8, the height of the tube frame 120 can be adjusted by the frame supporter 130 provided at both ends of the tube frame 120 so that the reinforcing bars can be placed within the allowable tolerance in the vertical direction.

Specifically, the thickness of the concrete slab of the cement concrete pavement may be varied depending on the situation, and the vertical height of the reinforcing bar may vary depending on the thickness of the slab. Therefore, the frame supporter 130 can adjust the position of the reinforcement guide 100 while moving vertically, thereby overcoming the above-described problem.

9, the plurality of guide tubes 110 of the reinforcing bar guide 100 have a predetermined curvature in a forward horizontal outward direction symmetrically with respect to a pair of guide tubes 110 at the center .

This is to induce deformation of the shape of the reinforcing bar based on the curvature of the guide tube in order to prevent the sagging of the reinforcing bars.

In addition to the above-described configuration, the guide tube 110 may be formed so that the diameter of the guide tube 110 is narrowed toward the end where the reinforcing bar is laid, or the guide tube 110 is inclined upward.

More specifically, the reinforcement guide 100 may have a holding device for fixing the reinforcing bars, and the holding device may be any one of an electromagnet, a rolling device, and a hydraulic device.

That is, after the reinforcing bars are laid from the guide tube 110, the reinforcing bars positioned at the right positions prevent the bent or bent state before being buried in the concrete due to the weight of the concrete (C) The present invention provides a tensile force to the reinforcing bar at the moment when the concrete is poured into the reinforcing bar so that the reinforcing bar is placed in the correct position in the concrete without being bent by the weight of the concrete to be laid.

Thus, since the reinforcing bars can be disposed within the allowable tolerance by the holding device, it is not necessary to perform additional work using the auxiliary reinforcing bars or supports.

The holding device can be driven in various ways that can instantaneously apply a tensile force to the reinforcing bars when the concrete C is laid. As an example, the reinforcing bars may be moved between the two rollers of the rolling device, Pressure can be applied to the reinforcing bars by applying pressure to the reinforcing bars through the hydraulic device, and electromagnets can be installed at the ends of the guide tubes 110 to apply a tensile force to the reinforcing bars.

On the other hand, in the previous continuous reinforced concrete pavement, the longitudinal and transverse reinforcing bars are previously laid out based on the support, and the concrete is poured. Since the concrete is not laid on the front surface, There was a problem that construction was very difficult.

As shown in FIG. 4, the plurality of guide tubes 110 are symmetrically formed so as to have a constant curvature in the outward horizontally outward direction to form a space portion in which the reinforcing bars are not laid. The concrete spreader 300, And the like, the concrete can be poured while traveling along the road from the front.

As a result, it is possible to effectively carry out the construction such as concrete pavement, tunnel entrance, bridge connection, lane separation, and the like in a tunnel with a very narrow working space.

9, each of the plurality of guide tubes 110 may have a tubular trunk 111 extending outwardly to guide the movement of the reinforcing bars at both ends thereof.

The fallopian tube 111 functions to guide the reinforcing bar easily to the inside of the guide tube 110 and to induce the coupler without interference.

Since the reinforcing bar guide fixing device D of the present invention is moved forward in the normal construction process, the tubular member 111 may be provided only in front of the guide tube 110. However, after the one-day installation is finished, , It is preferable to form the trunk tube 111 in the rear side as well.

10, the hopper unit 200 includes a hopper guide body 210 and an upper gate 220. The upper gate 220 moves up and down to adjust the width of the opening. have.

That is, the hopper unit 200 is installed with the concrete through the opening. By adjusting the size of the opening, the thickness of the concrete pavement can be adjusted. In some cases, the concrete is stagnated in the hopper unit 200 The size of the opening can be enlarged to smoothly discharge the concrete.

11, the hopper 200 may have an opening formed by a hopper guide body 210 having a quadrangular cross section and an upper gate 220, and the upper gate 220 may be vertically The width of the opening can be adjusted while moving.

At this time, the upper gate 220 may be provided in a later-described paver 400, and the height of the packaging surface may be adjusted simultaneously.

Further, the upper gate 220 may include a hinge shaft to adjust the size of the opening by adjusting the angle, and the hopper guide body 210 may include a cylinder or a hinge shaft to adjust the sizes of the openings. Can be configured. It will be understood by those of ordinary skill in the art.

Further, the lower end of the upper gate 220 is formed with an inclined portion which is inclined rearwardly, so that it is possible to prevent a phenomenon that the reinforcing bars flow down due to vertical drop when the concrete is poured. Thus, the concrete can be placed in a decelerated state along the inclined portion of the hopper guide body 210 and the upper gate 220.

The hopper guide body 210 may include a quadrangular guide portion 211 and a horizontal residual processing portion 212 coupled to the upper portion of the guide portion 211 to rotate in a vertical direction hingedly.

The remaining portion of the concrete supplied from the spreader 300, which will be described later, is not supplied to the hopper 200, And performs a dropping function.

Specifically, the concrete that has been laid down without falling along the guide portion 211 can be dropped downward by the hinge rotation of the residual processing portion 212.

3, a spreader 300 for supplying concrete to the hopper 200 is integrally connected to the front of the reinforcement guide 100, and the surface of the concrete poured in the rear is flattened The faber 400 can be integrally coupled.

That is, it is possible to integrate the bar reinforcement unit 100, the hopper unit 200, the spreader 300, and the paver 400, which have been conventionally separated and assembled, to integrate the equipment, And it is possible to secure the efficiency of the movement of the reinforcing bar guide fixing device (D).

7, a guide rail 140 is provided at the upper portion of the tube frame 120 of the reinforcement guide part 100 in a longitudinal direction and a driving roller 140 is disposed at a lower end of the conveyor 310 of the spreader 300. [ The driving roller 320 is slid along the guide rail 140 so that the conveyor 310 reciprocates in the lateral direction to supply the concrete.

In other words, the spreader 300 can reciprocate in the lateral direction along the guide rail 140, and prevents the concrete from being over- or under-laid at a specific position of the hopper 200, .

Meanwhile, the paver 400 may be coupled to the frame supporter 130 of the reinforcement guide unit 100. Thus, it is possible to integrate the reinforcement guide 100 and the paver 400 together.

The coupler 160 is coupled to the lower end of the frame supporter 130 by a coupler pin 150. The coupler 160 is coupled to a locking arm 170 provided on the tube frame 120, And can be mutually locked or unlocked.

As shown in FIG. 8, the frame supporter 130 can be pivoted from side to side in relation to the coupler 160 by the coupler pin 150. Accordingly, in order to form a gradient in the left and right direction, the height of one side of the frame supporter 130 is adjusted, and at the same time, the coupler pin 150 is pivoted around the center of the coupler pin 150, 400 can be adjusted.

As shown in FIG. 12, the coupler 160 includes a locking rod 161 to lock or unlock the coupling arm 170 via the locking rod 161. When the locking arm 160 is unlocked from the coupler 160, the paver 400 and the tube frame 120 of the reinforcement guide 100 can be separated from each other.

By separating the locking arm 170 after one day of installation, only the reinforcement guide 100 can be easily transferred.

8, the folding type wheel 190 is provided at the lower part of the reinforcement guide part 100. The folding type wheel is folded at the time of construction to be provided on the side of the frame, and after the completion of the construction, do. The folding wheel 190 may be folded by using a cylinder or the like.

A plurality of reinforcing through holes 181 are formed in the rear of the tube frame 120 of the reinforcement guide 100 to support a section of the concrete to ensure continuity of construction.

Specifically, the mold 180 is provided so that the reinforcing bar can move through the reinforcing through hole 181, so that the end of the concrete pavement surface is supported after one day of construction, so that continuity of construction can be ensured at the end of the pavement surface .

13, the mold 180 is formed of a pair of mold bodies 182 provided on the upper and lower sides, and a plurality of reinforcing through holes 181 The reinforcing groove 181a may be formed at the corresponding position.

That is, the mold 180 is detachably attached to the tube frame 120, and is attached to the tube frame 120. When the construction is interrupted, the mold 180 can be separated to support the section of the concrete. Thus, it is possible to prevent the formwork 180 from being interfered with during the concrete installation process during the construction process.

Therefore, it is preferable to form the mold 180 by a pair of mold bodies 182 so that the mold 180 can be easily separated from the reinforcing bar and fastened to the tube frame 120. In some cases, And a U-shaped reinforcing through hole 181 may be formed on the upper surface.

Also, as shown in FIG. 14, a plurality of reinforcing through holes 181 may be formed in the molding body 182 of the mold 180 so as to open the lower portion.

Thus, the mold 180 can be easily removed only by lifting the mold body 182 upwards after the concrete is poured.

15 is a perspective view showing a state in which a reinforcing bar receiving portion 500 is provided in front of the form after the reinforcing bars are laid and the concrete is laid.

Reinforced concrete can be struck down by the load due to concrete pouring. 16, the reinforcing bar fixing unit D is provided with the reinforcing bar receiving unit 500, and the height of the reinforcing bar supporting unit 500 is adjustable, so that the reinforcing bar can be supported so that the reinforcing bar is positioned within the allowable tolerance even after the concrete is laid .
