[Detailed Description of the Invention] <Field of Application of the Invention> The present invention is applicable to concrete covers for U-shaped grooves,
Alternatively, the present invention relates to a reinforcing bar clamping mechanism that is useful when installing reinforcing bars in a formwork device when molding concrete products such as concrete blocks.

<Background technology and its problems> A method is known in which a metal plate is bent into a box shape as a formwork for forming concrete products, and concrete is poured into the formwork together with reinforcing bars or alone and hardened. .

By the way, in order to set the above-mentioned reinforcing bars in the formwork, it is necessary to install supports etc. in the formwork so that they are placed in the middle of the concrete. There was a risk that the installation position would be misaligned when it was inserted.

<Object of the present invention> The present invention has been proposed in view of the above-mentioned circumstances, and allows for easy setting of reinforcing bars in formwork, as well as accurate setting of reinforcing bars while supporting them during concrete pouring. It is an object of the present invention to provide a device which can perform setting and which does not cause displacement of reinforcing bars even if vibration is applied especially when concrete is poured.

<Example> Next, an example of a formwork apparatus for arranging reinforcing bars using the reinforcing bar clamping mechanism of the present invention will be described as shown in the drawings.

Fig. 1 is a partially exploded exploded plan view showing the formwork components, Fig. 2 is a schematic perspective view showing the state before assembly, Fig. 3 is a schematic perspective view showing the tightened state, and Fig. 4 is a side view. FIG. 5 is a plan view, FIG. 6 is a side view showing an expanded state, and FIG. 7 is a plan view.

In these figures, 1 is a formwork body, which is formed by notching a metal plate such as an iron plate, and in the case of the illustrated example, a front wall 3, a rear wall in the four sides of a bottom plate 2 formed as a rectangular flat plate. section 4, left side wall section 5 and right side wall section 6
are installed in succession.

Each of these side wall portions 3, 4, 5, 6 is provided with folding lines 7, 8, 9, 10 at the boundary with the bottom plate 2, and each of these folding lines 7, 8, 9, 10 It is bent into an L shape and stands upright.

In addition, in the case of the illustrated example, the front and
A folding line 7 provided at the base of each rear side wall portion 3, 4,
Both end portions of 8, that is, left and right side wall portions 5 and 6
Cuts 7A, 7B, 8A, 8B are formed in the proximal extending direction of each side edge 5a, 5b and 6a, 6b, so that the folds formed at the base of the left and right side walls 5, 6 are Curves 9 and 10 are the front and rear side walls 3,
It is arranged to be formed at a position slightly closer to the inside than each side edge 3a, 3b and 4a, 4b of 4. Therefore, when the side walls 3, 4, 5, and 6 are bent and erected, the left and right side walls 5,
The side edges 5a, 5b and 6a, 6b of 6 are pressed against the inner surfaces 3c, 4c of the front and rear side walls 3, 4.

In addition, each of the bent and erected side wall portions 3, 4,
As mentioned above, since the flat metal plates 5 and 6 are bent and erected from the folding lines 7, 8, 9, and 10, the elastic force of the metal plates themselves generates bending reaction force on each side wall. The force that causes 3, 4, 5, and 6 to move outward is maintained.

Next, reference numerals 11, 12, 13, and 14 are reinforcing portions, and in the case of the illustrated example, each one side edge 11a, 12a, 13a, 14a of the thick long metal plate is attached to the outside near the tip of each side wall portion. Attached by welding to the side surface, each of both end portions 11B, 1 of each reinforcing portion 11, 12, 13, 14
1C, 12B, 12C, 13B, 13C, 14
B, 14C are the attached side wall parts 3, 4,
It is arranged so as to protrude from both sides of 5 and 6. In addition, each of the above-mentioned both end portions 11B, 11C, 12
B, 12C, 13B, 13C, 14B, 14C have pin insertion holes 15, 1 formed vertically through them.
6, 17, 18, 19, 20, 21, and 22 are provided in a protruding manner. Of the reinforcing parts, the mounting height positions of the reinforcing parts 11 and 12 attached to the front and rear side walls 3 and 4 are approximately the same height position, and the mounting height positions of the reinforcing parts 11 and 12 attached to the left and right side walls 5 and 6 are approximately the same height position. The installation height position of each reinforcing part 13, 14 is the above-mentioned reinforcing part 1.
1 and 12 are attached at positions shifted upward or downward by their wall thickness. Therefore, each reinforcing portion 11, 12, 13, 14 has both end portions 11B,
11C, 12B, 12C, 13B, 13C, 14
The through holes 15 and 19, 16 and 21, 17 and 20, 18 and 2 are located so that B and 14C are adjacent to each other and overlap each other vertically.
2, each side wall portion 3, 4,
5 and 6 are assembled and installed at predetermined positions.

Next, 23 is a fixing pin, and each of the corresponding pin insertion holes 15 and 19, 16 and 21, 17 and 2
0, 18, and 22, and the distal end portion of this pin 23 has a tapered portion 23A, and the remaining base end portion fits into each of the holes 15 to 22. The diameter shaft portion 23B is formed. Therefore, the pin 23 is connected to each hole 1.
5 to 22 is the state in which the equal diameter shaft portion 2 is inserted.
In the state where 3B is fitted, each corresponding hole 15
and 19, 16 and 21, 17 and 20, and 18 and 22 have their axes aligned with each other, and each side wall portion 3, 4, 5, 6 is tightened and fixed in a predetermined position.

On the other hand, in a state where the tapered portion 23A of the pin 23 fits into each of the holes 15 to 22, each hole 1
A gap is maintained between the circumferences of the holes 5 to 22 and the outer circumference of the tapered portion 23A, so that each side wall portion 3,
4, 5, and 6 are bent outward by the gap due to the bending reaction force of the metal plate itself, and the opening side is enlarged.

Therefore, when concrete is to be poured and molded using the formwork apparatus having the above configuration, first, the formwork 1 is firmly assembled and fastened to a predetermined assembly size before concrete is poured. The tightening and fixing operation of this formwork is performed using each of the four fixing pins.
Through holes 15 and 19, 16 and 21, 1 corresponding to 3
7 and 20, 18 and 22 are press-fitted, and the equal diameter shaft part 2
3A fits into each of these holes.

Then each of the holes 15 and 19, 16 and 21, 17
and 20, 18, and 22 are in a state where their axes are aligned, and the respective side wall portions 3, 4, 5, and 6 are firmly tightened and fixed. In this state, concrete is poured into the formwork 1 through the opening opening above it, or after reinforcing bars are placed, concrete is poured in and cured to harden the concrete, thereby forming the mold.

Next, in order to take out the concrete molded product from the formwork 1 after the above-mentioned forming, each of the holes 15, 19, 1
6 and 21, 17 and 20, and 18 and 22, respectively, and the fixed pin 23 with the equal diameter shaft portion 23B fitted in each of these holes, is inserted into each of these pins 2.
A tool or a push-back member of a device (not shown) is pressed against the tip of the taper portion 23A of No. 3, that is, the lower end in the figure, to push each pin 23 upward in the figure, and the holes 15 and 19, 16 and 21, 17 and 20, and 1
8 and 22 to fit the tapered portion 23A. Then, the outer periphery of the fixing pin 23, that is, the tapered portion 23
A gap is maintained between the outer periphery of A and the hole periphery of each hole 15 to 22, so that each side wall portion 3,
4, 5, and 6 are bent outward by the bending reaction force caused by the bending lines 7, 8, 9, and 10, and are deformed so as to widen the upper part of the formwork 1. Therefore, the concrete molded product and each side wall portion 3, 4, 5, 6 are easily separated,
Since the opening side of the formwork 1 is widened, the concrete molded product can be easily taken out from the formwork 1.

After the molded product has been taken out, the mold 1 is cleaned and then tightened and fixed to a predetermined assembly size in order to be used for molding again.
3 from the upper end and open each hole 15 and 19, 16 and 2.
1, 17 and 20, and 18 and 22, and each pin 23 is inserted into the hole up to its equal diameter shaft portion 23B, the corresponding holes 15 and 19, 16, 21, 17 20, 18, and 22 are in a state where their axes are aligned, and each side wall portion 3, 4,
5 and 6 are tightened and fixed at predetermined assembly positions.

Next, an example of an automated device for manufacturing a concrete molded product using the formwork 1 will be described.

FIG. 8 is a diagram showing the formwork lifting and unloading device 100,
This device is used to move formwork 1 into which concrete has been poured from a continuous production line to a position on the side of the line, or to install formwork 1 from a position on the side of the line to a position on the line for use in the next manufacturing process. This is the device.

In the illustrated example, only the formwork latching mechanism part of this device 100 is clearly shown, but the entire device is configured to be movable between a position on the line and a position to the side of the line by means of guide rails and moving rollers (not shown). It is something that will be done.

That is, in the illustrated example, the support frame 101, which is formed in a downward U-shape, is supported by a moving mechanism (not shown) so as to be movable between a position on the line and a position on the side of the line. This frame 101 has one hanging frame 102.
The middle part of one arm 104 is rotatably supported by a fulcrum shaft 105 on a projecting piece 103 that projects further, and the middle part of the other arm 108 is supported on a projecting piece 107 that projects from the other hanging frame 106. is rotatably supported by a fulcrum shaft 109. Further, at the lower ends of each of the arms 104, 108, formwork hooks 110, 11 extending in the horizontal direction are provided.
1 is formed, and these hooking portions 110, 111 can hook the flange-like reinforcing portions 11 and 12 or 13 and 14 formed on the periphery of the formwork 1 so as to sandwich them from both sides. There is. A link arm 1 is provided between a portion of one arm 104 slightly closer to the lower end than the pivot portion and the upper end of the other arm 108.
Both ends of the arm 104 are pivotally connected, and a hydraulic cylinder 114 is connected between the upper end of one arm 104 and a protrusion 113 formed in the middle of the support frame 101. That is, when the hydraulic cylinder 114 is extended, one arm 1
04 is rotated counterclockwise in the figure around the fulcrum shaft 105, and as a result, the link arm 112
The other arm 108 is rotated clockwise in the figure about a fulcrum shaft 109 via the fulcrum shaft 109. As a result, the formwork hanging parts 110, 111 provided at the lower ends of each arm 104, 108 are closed so as to be close to each other, and hooked onto the flange-like reinforcement parts 11, 12 or 13, 14 of the formwork 1 described above. It is now possible to stop it. Further, contrary to the above, when the hydraulic cylinder 114 is driven to shorten, each of the arms 104 and 108 is moved to the formwork retaining portion 1 at the lower end.
The legs 10 and 111 are opened so as to separate from each other, and are detached from the reinforcing parts 11 and 12 or 13 and 14 of the formwork 1, so that the formwork 1 can be released. Although the formwork hooking parts 110 and 111 are not necessarily clear from the drawing, since they are formed in a long shape extending in the horizontal direction, the reinforcing parts 11 and 12 of the formwork 1
Or, the state of engagement with respect to 13 and 14 is stabilized.

Next, FIGS. 9 to 11 show an example of a mold clamping device 200 (the same mold loosening device is also used) for assembling and tightening the mold 1.

A fixed support frame 201 is supported by a base (not shown). Reference numeral 202 denotes a movable frame, which can be raised and lowered in the vertical direction by a driving means such as a hydraulic cylinder (not shown). In the illustrated example, a top plate 203 and a bottom plate 204 are installed on the top and bottom surfaces of the movable frame 202, and support four rotating shafts 205, 206, 207, and 208 so as to be rotatable. . These rotation axes 205
~208 have passive gears 205A, 206A, 207A, and 208 located at the same height near the upper end, respectively.
A is fixed to the drive shaft, and each of these gears 205A to 20
8A is meshed with a drive gear 210 that is driven and fixed to a rotation shaft 209 that is rotated by a motor (not shown). That is, each of the passive gears 205A to 208A is rotated by the drive gear 210 driven by the rotational force of the motor, and each of the rotation shafts 205
-208 are designed to be rotated at the same time in the same mode.

In addition, a rotation transmission mechanism 214 is connected to and connected to the lower ends of each of the rotation shafts 205 to 208 by means of gears 211, 212, 213, and a chain (not shown) that is meshed and rotated between these gears 211 and 212 and 212 and 213. A pin engaging portion 215 provided at the rotating end and detachable from the pin 23 of the formwork 1 can be rotated. Although the rotation transmission mechanism 214 is shown in the drawing only as being provided at the lower end of the rotating shaft 205, a mechanism with the same configuration is provided at the lower end of each of the other three rotating shafts 206 to 208. There are also locations nearby. That is, the pin engaging portion 214 engages with four mold clamping pins 23 provided at the four corners of the formwork 11, and these pins 23
The formwork 1 can be tightened by screwing it forward. Moreover, when loosening the formwork 1, the pin 23 is screwed back in the opposite manner to the above, and the formwork 1 can be loosened.

Next, FIGS. 12 to 14 show an apparatus 300 for taking out concrete products from the formwork 1. This take-out device 300 is a device for sucking and releasing a concrete product, which has been put into the formwork 1, cured and hardened, and released from the formwork 1 after the formwork 1 is loosened. In the example shown,
A movable wheel 302 is attached to the main frame 301, and is configured to be rotated by a motor 303 so as to be movable between a position on the line and a position to the side of the line along a guide rail (not shown).

An elevating frame 305 that is moved vertically by a hydraulic cylinder 304 is disposed and supported below the main frame 301, and a guide rod 306 that is erected from this frame 305 is inserted through a guide hole 307 of the main frame 301. Vertical movement at a predetermined position is realized. Further, below the elevating frame 305,
A concrete product adsorption section 308 is provided protrudingly using the lower surface 308A as an adsorption surface. This suction part 30
Numeral 8 communicates with a compressor (not shown), and by pasting a highly sealing material such as rubber around the periphery of the suction surface, it is possible to suction and suction concrete products. In addition, this suction part 308
A guide rod 309 passes through a guide hole (not shown) in the elevating frame 305, and also passes through an insertion hole 310 in the main frame 301 and protrudes upward.
A locking portion (not shown) is provided at the upper end and is locked to the main frame 301 to prevent it from falling off downward. Further, although not shown, a resilient material such as a coil spring is interposed between the lifting frame 305 and the suction part 308, and provides a buffer when the suction part 308 is pressed against the upper surface of the concrete product. It is beginning to take effect.

In the above configuration, when the formwork 1 with the formed concrete product still housed in the final formwork is sent along the line to a position below this take-out device 300, the formwork 1 is placed on the line. It is fixed by suction from the lower surface side by an electromagnet (not shown), and when the hydraulic cylinder 304 is driven to extend, the suction part 308 is lowered together with the elevating frame 305, that is, toward the upper surface of the concrete product in the formwork 1. When the suction part 308 reaches the upper surface of the concrete product in the formwork 1 and the elevating frame 305 is further lowered, the elastic force of the elastic material interposed between the elevating frame 305 and the adsorbing part 308 described above is absorbed. As a result, the suction portion 308 is strongly pressed against the concrete product. In this state, when a compressor (not shown) is operated and the concrete product is sucked from the suction section 308, the concrete product becomes adsorbed by the suction section 308. Therefore, in this state, when the hydraulic cylinder 304 is shortened and the elevating frame 305 is pulled upward, only the concrete product is moved to the suction part 30, since the formwork 1 is suctioned and fixed by the electromagnet as described above.
8, and is lifted upward while being adsorbed to formwork 1.
It will be taken out from inside and released from the mold. next,
When the moving motor 303 is driven while the concrete product is still adsorbed, and the moving wheel 302 is rotationally driven, the entire main frame 301 is moved along a guide rail (not shown), and is moved from the position on the line to the line. The concrete product can be transported to a lateral location. Then, at this position on the side of the line, the hydraulic cylinder 304 is extended again, the elevating frame 305 is lowered, and the concrete product adsorbed on the suction section 308 lands, and when the compressor is further stopped, the concrete product is transferred to the suction section. 308, and the mold release process can be completed.

Next, FIG. 15 shows a vacuum cleaner 40 for cleaning the inside of the formwork 1 after taking out the concrete product.
It indicates 0.

That is, at the lower end of a rotating shaft 401 rotated by a motor (not shown), a base end is attached to a tightening metal fitting 402.
A rotating brush 404 is formed by attaching a large number of steel wire rods 403, which are fastened together with the tip end as a free end, and which are attached in a bundle to form a bundle of a large number of steel wire rods 403 arranged in several different stages in the axial direction and arranged around the axis as a whole. This brush 404 is movable up and down by a hydraulic cylinder (not shown), and is adapted to remove concrete scum and the like by rotating and sliding in contact with the formwork 1.

Then, the inside of the mold 1 that has been cleaned is subjected to a coating process of applying mold release oil prior to the next molding process, and is then coated with a mold clamping device 200 shown in FIGS. 9 to 11. The mold can be clamped by screwing the pin 23 forward.

Then, concrete is poured into the formwork 1 after the above-mentioned oil application for the next molding.

That is, FIGS. 16 to 18 show a concrete charging hopper 500. FIG. This hopper 500 is used to charge a predetermined amount of concrete base into the formwork 1 which has been clamped into a predetermined shape, and weighs the concrete base fed from a mixer (not shown) to form a single concrete product. A suitable amount of concrete base material can be poured into the formwork 1. That is, in the illustrated example, a hopper 500 whose inner wall surface 501 is downwardly contracted has a slide opening/closing lid 502 at its lower end.
The lid 502 is opened and closed by a hydraulic cylinder (not shown). Further, a frame 503 extends on one side of the hopper 500, and a balance weight 504 is attached near the tip of the frame 503. Also,
The above hopper 500 and the above balance weight 504
A fulcrum 505 is provided at an intermediate position to be rotatably engaged with a fulcrum member provided on a base (not shown). When the hopper 500 is empty, due to the weight of the balance weight 504,
The balance weight 5 is centered around this fulcrum 505.
The 04 side is lowered and the hopper 500 side is lifted upward.

Further, when a concrete base material is fed into the hopper 500 and a predetermined amount necessary for forming is introduced, the hopper 500 side is lowered around the fulcrum 505 and the balance weight 504 side is lifted upward. When such seesaw movement is detected and the hydraulic cylinder (not shown) is extended, the opening/closing lid 502 opens the lower end opening of the hopper 500, and the concrete base material can be placed into the formwork 1 located below. can. When the inside of the hopper 500 becomes empty after loading, the balance weight 504 side is lowered and the hopper 500 side is lifted up, and by detecting this seesaw movement, the hydraulic cylinder is operated to shorten, and the opening/closing lid 502 can be closed.

As described above, a predetermined amount of concrete base material is placed in the formwork 1, and then reinforcing bars are supplied and arranged in the formwork 1.

Next, FIGS. 19 to 21 show an automatic reinforcing bar installation device 600 equipped with a reinforcing bar clamping mechanism according to the present invention. This device 600 grasps grid-shaped reinforcing bars stacked on the side of the line one by one and supports them so that they are installed at predetermined positions in the formwork 1 on the line, and supports the concrete pouring process in the previous process. This function is to place reinforcing bars at predetermined positions in the concrete base that has been poured. Alternatively, reinforcement may be arranged in the formwork in advance before concrete is poured.

In the illustrated example, the device 600 has the following functions:
Four movable wheels 602 are pivotally supported on a support frame 601, and are in rotational contact with a guide rail 603 fixedly disposed on a base (not shown), so that they can freely reciprocate between a position on the line and a position on the side of the line. . Further, four guide rods 604 are suspended below the support frame 601, and an elevating frame 605 is attached so as to be movable up and down. Note that a hydraulic cylinder 606 is disposed between the lift frame 605 and the support frame 601. Additionally, four support rods 607 are attached to this elevating frame 605.
is hanging downward. Each of these rods 607
The rods 607 are supported in a distributed manner by two movable rods 609 and 610, which can be moved horizontally towards and away from each other by rotating the operating handle 608, so that the installation spacing between the rods 607 can be easily adjusted by operating the handle 608. It's getting old. That is, one movable rod 609 has a female threaded portion 612 screwed onto a rotary male threaded shaft 611 that is integrated with the handle 608, and the other movable rod 610 has a male threaded shaft 611 that is integral with the handle 608.
A female threaded portion 616 is screwed onto a rotary male screw shaft 615 having a passive gear 614 that meshes with a drive gear 613 pivotally connected to the tip of the handle 6.
When rotating 08, each rotating male screw shaft 612 and 615
is reversed so that the moving rods 609 and 610 can be moved relative to each other. Further, an operating arm 619 is attached to each of the support rods 607. The operating arm 619 is rotatably supported in the middle by a fulcrum pin 617 and has a recess 618 for hooking a reinforcing bar on one side of the tip. Further, a hydraulic cylinder 620 for operation is provided between the base end of each arm and the midway portion of each rod 607. That is, when the hydraulic cylinder 620 is extended, the operating arm 619 is rotated clockwise in FIG. When the cylinder 620 is driven to shorten, the tip of the arm 619 closes between the rod 607 and the reinforcing bar. Note that each of the hydraulic cylinders 620 is set to operate in a coordinated manner, and each operating arm 619 is configured to open and close at the same time. As a result, the reinforcing bars (not shown) are moved to a position above the lattice-shaped reinforcing bars (not shown) that have been stacked in advance on the side of the line, and the hydraulic cylinder 620 is activated to lower the elevating frame 605, and the tip of the reinforcing bar clamping mechanism 600 is attached to the topmost reinforcing bar. Then, each hydraulic cylinder 620 is shortened and driven to close the operating arm 619 and the reinforcing steel is latched.Then, the elevating frame 605 is raised and the movable wheel 602 is rotated by a motor (not shown) to bring it onto the line. is moved along the guide rail 603 to a predetermined position. Then, the elevating frame 605 is lowered again from above the formwork 1 that has been previously installed on the line, and the operating arm 619 is opened with the reinforcing bars installed at predetermined positions within the formwork 1. Reinforcing bars can be installed inside the formwork 1.

22 and 23 illustrate a concrete surfacing apparatus 700. This device is a device for leveling and finishing the surface of the concrete within the formwork after concrete is poured into the formwork 1. In the illustrated example, this device 700 is configured such that a roller 702 that rolls against a fixed guide rail 701 is driven by a motor (not shown), and supports a support frame 702 so that it can move within a range that covers the formwork area.
It is attached to 03. A vertical rod 704 is attached to this frame 703 so that its height can be adjusted manually, and its vertical position can be freely adjusted.The middle part of a horizontal rod 705 is fixed to the lower end of this rod. A flat synthetic rubber spatula 706 is clamped and fixed by a fixing plate 707 between them. Therefore, by driving the roller 702 and reciprocating it, the spatula 706 can flatten the concrete surface within the formwork.
