Abstract

PURPOSE:To easily arrange reinforcements in a lattice type by dropping a lower and an upper side reinforcement oriented in two orthogonal directions into recessed grooves and orienting them in parallel during the reinforcements fall by their dead weight along the respective lower or upper guide bar surfaces on an inclined frame fabricated in site. CONSTITUTION:Plural upper reinforcements 2-2 oriented in an inclined orthogonal direction are mounted on a reinforcement storing base 19 of the inclined upper side part of the upper guide bars 8 to be lowered by their dead weights to the inclined lower side. A descending reinforcement 2-2 falls into a recessed groove 9' having no guide piece 10' on the inclined lowest step. The reinforcement 2-2 pushes down the arm of a hinge 12' downward and the guide piece 10' is raised at an inclined lower side edge of the recess 9' to open the recess 9'. A next descending upper reinforcement 2-2 touches this rising guide piece 10' and falls into a recess 9' one step upper. In this way, while plural upper reinforcements 2-1 descend from the upper surface of the inclined upper guide bars 8, they fall sequentially from a recessed groove 9' into the adjacent upper recess 9' to insert the reinforcements 2-2 into all the recesses 9'. A group of upper side reinforcements 2-2 kept at a specified interval and in parallel to each other is formed in the direction orthogonal to a group of lower side reinforcements 2-1.

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method and apparatus for arranging reinforcing bars in a lattice pattern for assembling large prefabricated lattice-shaped reinforcing bars in a ground assembly process.

[Problems to be solved by this invention]

The present invention proposes a method and apparatus for arranging reinforcing bars in a lattice pattern for assembling large prefabricated lattice-shaped reinforcing bars each weighing approximately 10 tons in a semi-automated ground assembly process.

[Means to solve the problem]

The present invention is a method for arranging reinforcing bars in a lattice pattern for assembling lattice reinforcing bars in the ground assembly process, in which a plurality of lower guide strips and upper guide strips are arranged in the ground at predetermined intervals and have grooves in the width direction for holding reinforcing bars. They are arranged on the assembly frame in directions orthogonal to each other, the assembly frame is tilted in the direction of the lower guide strip, and a plurality of lower reinforcing bars are placed on the upper end of the inclined lower guide strip, oriented in the direction perpendicular to the inclination. , lower it by its own weight along the upper surface of the guide strip, drop one of the lower reinforcing bars into each groove, then tilt the foundation assembly frame toward the upper guide strip, and place multiple upper reinforcing bars at the upper end of the inclined upper guide strip. The method is characterized in that the reinforcing bars are placed in a direction perpendicular to the inclination, are lowered by their own weight along the upper surface of the guide strip, and one of the upper reinforcing bars is dropped into each groove. Another invention is a lattice-like arrangement device for reinforcing bars for assembling lattice-like reinforcing bars in a ground assembly process, which comprises a ground assembly frame that can be tilted in two orthogonal directions, and a ground assembly frame that is tiltable in two orthogonal directions; It has a plurality of lower guide strips and upper guide strips oriented in the direction, and each of the lower guide strips and the upper guide strip has a width that allows one of the reinforcing bars oriented in the direction perpendicular to the slope to fall down the sloped upper surface by its own weight. A reinforcing bar holding part with a guide piece that stands up on the inclined lower edge of the groove is provided at a predetermined interval. When there is no reinforcing bar, the guide piece stands up to open the groove, and when a reinforcing bar enters, the load causes the guide piece to fall down and close the groove, and the reinforcing bar holding part of the upper guide line moves downward to the next inclined position. When there is no reinforcing bar in the side groove, the guide piece falls down and closes the groove, and when reinforcing bar enters, the load causes the guide piece to rise and open the groove. shall be.

Figure 1 shows that in the ground assembly process, prefabricated reinforcing bars 3 are assembled in large rows in a semi-automated process, and are hoisted onto a stock frame 5 using a large crane 4, etc., and stocked, thereby reducing the time lag between assembling and installing the reinforcing bars. The aim is to eliminate this problem.

The ground assembly frame 1 of this reinforcing bar lattice arrangement device has a rectangular shape as shown in Figures 1 and 2, and telescopic columns 6 are attached to the lower parts of two adjacent sides, so that it can be tilted in two orthogonal directions. Possible and not possible.

A plurality of lower guide strips 7 and upper guide strips 8, which are parallel to the sides and oriented in mutually orthogonal directions, are arranged on the flat upper surface of the mount with their upper surfaces aligned in one plane.

FIG. 3 shows a state in which the telescopic struts 6 are extended and contracted to tilt the ground assembly frame 1 in the direction of the lower guide strip. The upper surface of the lower guide strip 7 has a fourth
As shown in FIG.
1 maintains a predetermined interval and is provided between the intersection with the upper guide strip 8. Note that this groove 9 has a depth that is approximately twice the diameter of the reinforcing bar 2. A hinge 12 parallel to the guide strip 7 is rotatably attached to a position below the slope of the groove 9 of the lower guide strip 7 with a pin 13 .

The inclined lower part of this hinge 12 forms a balance load 14 part, the upper part forms an arm 15 projecting from the concave groove 9 position, and the guide piece 10 is attached to the upper end of this hinge 12 with a pin 16.
It is pivoted so that it can rotate freely.

When the reinforcing bar 2 is not in the groove 9, the hinge 12 stands upright with the balance load 14 at the bottom, and the stopper 17 protruding from the hinge 12 pushes up the guide piece 10, so that the lower edge of the groove 9 A raised groove 9 is opened at the opening. When the reinforcing bar 2 enters the groove 9, the load of the reinforcing bar 2 applied to the arm 15 overcomes the balance load 14, tilts the hinge 12 laterally, and at the same time pushes the guide piece 10 with the stopper 17 to collapse it and close the groove. The upper surface of the lower guide strip 7 is a flat surface. In addition, in FIG. 5, reference numeral 18 denotes a swivel protruding from the guide strip 7 that abuts the upper surface of the guide piece 10.

A plurality of lower reinforcing bars 2-1 are placed on the reinforcing bar 19 on the upper side of the slope of the lower guide strip 7 configured in this way, oriented in the direction orthogonal to the slope as shown in FIG. lower it. In the holding part 11, the guide piece 10 rises at the lower edge of the groove 9 and opens the groove 9, so that the reinforcing bar 2-1 descending along the upper surface of the inclined lower guide strip 7 first reaches the uppermost inclined stage. It hits the guide piece 10 and falls into the groove 9.

The reinforcing bar 2 that has entered the groove 9 presses down the arm 15 of the hinge 12 with its load, causing the hinge 12 and the guide piece 10 to fall down, making the upper surface of the guide strip 7 a flat surface. Therefore, the reinforcing bar 2-1, which then descends on the upper surface of the guide strip 7, falls into the groove 9 located one step below. In this way, in the process of descending on the upper surface of the lower guide strip 7, the plurality of lower reinforcing bars 2-1 fall one after another from the groove 9 located at the upper level of the slope to the groove 9 located at the lower level, and all the grooves are The reinforcing bars 2-1 are housed in 9, forming a group of lower reinforcing bars 2-1 that are arranged in parallel at a predetermined distance in one direction.

After arranging the lower reinforcing bars 2-1 in one direction, the base assembly frame 1 is tilted in the direction of the upper guide strip 8 by extending and contracting the telescopic columns 6, as shown in No. 60. As shown in Fig. 7.8, on the upper surface of the upper guide strip 8, there is a reinforcing bar holding portion 11° provided with a groove 9' in the width direction of the guide strip 8 and a guide piece 10° on the lower edge of the groove 9'. The distance is maintained. Note that this groove 9' has a depth approximately equal to the diameter of the reinforcing bar 2.

Between the two concave grooves 9' and 9' of the upper guide strip 8, a hinge 12'' parallel to the guide strip 8 is rotatably attached with a pin 13''.The inclined upper side of the hinge 12'' is The balance load consists of a 14" portion, the lower part has an arm 15" extending from the concave groove 9" at the lower inclined position, and the guide piece 10" is pivotally attached to the upper inclined part of the hinge 12° with a pin 16". It is.

When the reinforcing bar 2 is not inserted into the groove 9' on the lower side of the slope, the hinge 12' falls sideways due to the balance load 14', the guide piece 10' falls over the groove 9' and closes, and the guide strip 8 of-
Let F-plane be a flat surface. Reinforcement bar 2 is placed in the concave groove 9゜ at the bottom of the slope.
When the load is applied to the arm 15'', the hinge 12' is raised, and at the same time the lower surface of the guide piece is moved to the stopper 17.
Push it down with ゛, stand the guide piece 10゜ on the inclined lower edge of the groove, and open the groove 9゜.

As shown in Fig. 6, a plurality of upper reinforcing bars 2-2 oriented perpendicular to the inclination are placed on the reinforcing bar mounting stand 19 on the two sides of the upper guide strip 8 constructed in this way, and the self-weight is applied in the downward direction of the inclination. to lower it. Initially, the upper surface of the upper guide strip 8 is a flat surface, so the reinforcing bar 2-2 that descends first falls into the concave groove 9' to which the guide piece 10' at the lowest stage of the slope is not attached. This reinforcing bar 2-2 pushes down the arm 15'' with the hinge 12°, and pushes the guide piece 10'' up against the inclined lower edge of the groove 9'' to open the groove 9''. Therefore, the upper reinforcing bar 2-
2 comes into contact with this raised guide piece 10'' and falls into the concave groove 9'' one step above.In this way, the plurality of upper reinforcing bars 2-
In the process of descending on the upper surface of the inclined upper guide strip 8, the reinforcing bars 2 fall one after another from the grooves 9' located at the lower level of the slope to the grooves 9' located at the upper level one after another. -2
are accommodated, and a group of upper reinforcing bars 2-2 is formed which are arranged in parallel at a predetermined interval in a direction orthogonal to the group of lower reinforcing bars 2-1.

The upper and lower reinforcing bars arranged in this manner are fixed at their intersections by binding with binding wires, etc., to form lattice reinforcing bars 3.

[For production]

This invention consists of the above configuration. According to this method of arranging reinforcing bars in a lattice pattern, the lower reinforcing bars and the upper reinforcing bars oriented in two orthogonal directions are formed into concave grooves in the process of descending under their own weight on the lower or upper guide strips of the inclined foundation frame, respectively. The upper and lower reinforcing bars can be arranged in a grid pattern.

Therefore, even if the reinforcing bars are thick and heavy, it is possible to assemble the lattice-shaped reinforcing bars in the ground assembly process using a simple device without requiring excessive labor.

In addition, in the lower and upper guide strips of this assembly device, a guide piece rises at the lower edge of the groove into which the reinforcing bars are to be dropped, opening the groove, and reliably guides the reinforcing bars descending on the upper surface of the guide strip. It is dropped into the groove and held, allowing for accurate alignment of the reinforcing bars. Furthermore, when arranging the lower reinforcing bars first, the guide piece of the upper guide strip closes the groove and forms a flat surface, so that it does not interfere with the lowering and arrangement of the lower reinforcing bars. When arranging the upper reinforcing bars, the recessed groove of the lower guide strip contains the reinforcing bars and the guide piece closes to form a flat surface, which does not interfere with the lowering and arrangement of the upper reinforcing bars.

The lattice-shaped reinforcing bars, which are formed by binding the intersections of the upper and lower reinforcing bars arranged in a lattice pattern, can be lifted upward by a crane or the like, and easily separated by rotating the guide pieces from the holding parts of the upper and lower guide strips.

〔Effect of the invention〕

As mentioned above, this method of arranging reinforcing bars in a lattice pattern does not require excessive labor even with large diameter reinforcing bars, and can be easily arranged in a lattice pattern. Enables assembly of grid-shaped reinforcing bars.

Further, the arranging device according to the present invention has a simple mechanism and is easy to operate, and can reliably arrange reinforcing bars in a grid pattern.
