Description

TECHNICAL FIELD The present invention relates to a concrete mold fixing and fastening structure, a concrete mold and a concrete mold fixing and supporting bracket, and more particularly to a novel structure and a supporting metal that can more easily perform a continuous operation of a concrete mold. It is.

  When placing concrete in the construction of a wall in a concrete structure, after the reinforcement reinforcement as a skeleton of the structure is completed, concrete formwork (hereinafter referred to simply as formwork) is placed on both sides. In this case, separate members are arranged between the opposing concrete molds so as to maintain the molds at a required interval, and the concrete molds opposed by the separate members are arranged. Tighten and place and fix the butter material that supports the back of the concrete formwork so as to support the load acting on the concrete formwork when placing the concrete, and the concrete formwork unit constructed in this way is placed between the concrete formwork units. By supplying (pouring), the construction of the concrete structure is performed.

There are roughly two types of separate members used in the construction of the above-mentioned concrete formwork into units, that is, there are rod-like separators (round separators) and plate-like separators. Depending on the form of the concrete formwork or depending on the design of the enforcer, the formwork that is frequently used in the past is easy to manufacture the formwork, nailing to connect the formwork, etc. For this reason, concrete plywood made of wood plywood is often used because of its ease of work and ease of handling such as transportation and handling during construction due to its wooden form and light weight.

When the concrete formwork is woody in this way, for example, a rod-shaped separator as shown in an example in Japanese Patent Application Laid-Open No. 2004-027592 or “Product Catalog NO3 Concrete Formwork” (issued by Okabe Co., Ltd.) In a rod-shaped separate member in which a through-hole is drilled by a drill at a required pitch, and a screw at both ends is engraved in the through-hole of a concrete formwork that is used and arranged opposite to the reinforcement bar After inserting the screws so that each screw protrudes from the bottom plate and connecting the adjacent molds with nails or connecting metal fittings, a foam tie (trade name) is screwed to the screw, and then the concrete is placed on the foam tie. Place and fix the horizontal butter material that supports the concrete load acting on the formwork during installation, and tighten the concrete formwork continuously Construction of the mold is being carried out as.

  By the way, in the case of using the above-mentioned wooden concrete formwork, it is necessary to perform a plurality of drilling operations for inserting the rod-shaped separate member used to maintain the interval of the concrete formwork, In addition, the rod-shaped separate member must be inserted into the above-described insertion hole provided in the support plate of the concrete formwork that is arranged across the reinforcing bar reinforcement, and the insertion hole lacks accuracy. Therefore, it takes time for the work, that is, in assembling the formwork, workers are placed in pairs on both sides of the opposing formwork, and these workers are punched in the formwork arranged at intervals. It takes time to insert the rod-shaped separator while confirming the inserted insertion hole and screw the foam tie (trade name).

  Furthermore, a fixing metal member called a foam tie (trade name) is arranged on the threaded portion of the bar-shaped separator (round separator) by which a butter material for supporting the load due to the weight of the concrete acting on the formwork is fixed and tightened. It is necessary to stop, but there is a problem that this and the above-mentioned workers need to work in pairs, and when formwork is connected (unitized) such as fixing butter material to this foam tie In any work, such as mounting the rod-shaped separator (round separator) on the mold, screwing the rod-shaped separator (round separator) to the foam tie (trade name), fixing and fastening the butter material, etc. It takes time, and in particular, the screwing operation will affect the efficiency of construction, and it will be peeled off because the threaded portion of the bar separator (round separator) is entangled with the multiple insertion holes mentioned above Damage due to sexual deterioration Luo depletion as is severe concrete form, in addition, since the required workers in pairs will lead to labor costs increase.

  Further, in the case of using a metal concrete formwork for the purpose of reducing the labor of manufacturing the concrete formwork, enabling repeated use and reducing the cost, Japanese Patent Application Laid-Open No. 2001-027044 As can be seen in Japanese Patent Application Laid-Open No. 2002-174030, for example, most cases use plate-like separators (hereinafter also referred to as plate separators). The plate separator is tightly sandwiched between the concrete molds, and the concrete molds are fastened together with clip metal fittings for fastening the concrete molds for unitization, and further provided on the ribs of the concrete molds. Using the clip holes, a horizontal unit is attached to construct a unit.

  In addition, a corner foam is generally a connecting member at a corner portion of a concrete formwork such as a metal foam, in which a joining rib provided with a clip hole is fixed to a formwork base plate formed at a right angle or a suitable angle. This is to reduce the weight and simplify the form.

In addition, when using a metal concrete formwork, a plate separator is used as a separate member to maintain the spacing of the concrete formwork (when using a wooden concrete formwork) In some cases, plate separators are also used.) In order to sandwich the ribs on both ends of the concrete mold, there is a gap corresponding to the thickness (thickness) of the separator between the concrete molds after construction. After the concrete filled between the concrete molds is filled in this gap, it will overflow from the gap, and after the concrete is solidified, it overflows from the gap to the construction surface where the mold is removed Since the solidified concrete is formed as burrs and smoothness is required for the casting surface, the (斫) has caused the allowed to lower the workability because of the required work. In addition, the horizontal butterfly material for supporting the metal concrete formwork is fixed by using a clip hole different from the clip hole for fixing the plate separator provided on the vertical rib of the concrete formwork. Therefore, the work is complicated.

In rare cases, even when a metal concrete formwork is used, there is a case where construction is performed using a rod-like separator as in the case of the wooden concrete formwork described above. As described above, it is difficult to form through holes similar to the case of using a wooden concrete formwork, to make the separator insertion work complicated, and to close the through holes when unnecessary.

In addition, for concrete formwork, when the formwork is removed or dismantled after placing concrete, a plurality of screw parts connecting the bar separator (round separator) and the butterfly material clamp or foam tie (product name) are entangled with the dam plate. The mold is easy to hurt because it gives an impact to demolding, and when the cone cup is not used, this unnecessary screw part is hit with a hammer, bent and cut. (Round Sepa) may be separated by rotation. It also causes water leakage.

Further, in a commonly used cone cup (P-con or wooden shell) attached to the end of the separator, the separator is screwed into the cone cup formed by fitting a connection nut or a connection screw. Therefore, after the concrete is solidified, it must be removed by using a turning tool, which requires work.

For this reason, in recent years, corn cups made of synthetic resin have been used to eliminate the need to remove the corn cup. A gap is formed in the water, and rainwater enters from here to lose waterproofness, which causes water leakage.

However, the present invention is not limited thereto, and can be appropriately modified without departing from the technical idea of the present invention. Of course. In addition, unitization of the concrete formwork in one side is demonstrated for the simplification of description.

Hereinafter, embodiments of a concrete mold fixing and fastening support metal fitting according to the present invention will be described with reference to FIGS. 1 to 7 and FIG. 8 or reference numerals. The butterfly material clamp 20 bears the load on the intermediate rib 3 through the butterfly material.

As shown in FIG. 1, when the concrete formwork 1 is continuously constructed, a plurality of concrete formwork 1 are prepared against each other by sandwiching the reinforcing concrete reinforcing material (not shown). A plate separator 10 is inserted between the vertical ribs 2 of the concrete mold 1 to be sandwiched between the adjacent concrete molds 1 and 1a, and the clip holes 7 formed in the vertical rib 2 are used. Then, the concrete formwork 1 is constructed as a unit while the concrete formwork 1 is fastened integrally.

That is, the concrete formwork 1 has a structure in which vertical ribs and horizontal ribs as reinforcing materials are fixedly provided on one surface side of the dam plate 4 as a basic structure regardless of whether the material is made of wood or metal. Or, if necessary, a structure in which the surface of the peg 4 is replaced with a plywood or synthetic resin peg on the surface in contact with the concrete with rivets, screws or bolts. As shown in FIG. 6, on one side of the slat plate 4, the vertical rib 2 made of L-shaped steel as a reinforcing material is fixed at a position slightly retracted from the edge of the slat plate, in other words, The vertical rib 2 is configured such that the peripheral edge of the slat plate 4 slightly protrudes, and the slat plate 4 is fixed to the vertical rib and the horizontal rib, and the vertical rib 2 in this formwork, For details, see Forming a plurality of grooves 5 which is fitted a plate separator at appropriate intervals sheathing board protruding from the longitudinal ribs 2 existing on both sides in contact with preparative frame.

The groove 5 described above is formed in a direction perpendicular to the direction in which the longitudinal ribs 2 extend, the width h is set to a dimension in which the plate separator 10 is fitted, and the depth t is 1 of the thickness of the plate separator 10 described above. / 2, and the plate-like separator 10 is held by the groove 5 formed in the adjacent concrete formwork, so that when the concrete formwork is continuously arranged, there is a gap between the concrete formwork. This eliminates the occurrence of burrs due to the overflow of concrete from the gap, and ensures a smooth casting surface.

However, it is also possible to provide the groove 5 only in one of the vertical ribs 2 ′ in the concrete formwork. In this case, the depth t of the groove 5 is equal to the plate separator 10 alone. Of course. Furthermore, the grooves 5 are basically formed by cutting the vertical ribs 2 ′ from the above viewpoint, but the gap formed by the plate separator 10 when the plate separator 10 is sandwiched between the molds. From the viewpoint of preventing the overflow of the concrete, a thin plate is provided on the contact surface of the vertical rib 2 ′ so that a sufficient space (space) is provided in the vertical rib 2 for installing the plate separator 10. It is possible to form a groove by pasting, and such a configuration is effective for a metal concrete formwork.

As shown in FIG. 4, the plate-like separator 10 inserted between the concrete molds 1 has the thickness dimension of the structure to be constructed and the thickness of the concrete mold 1 (the thickness of the siding board 4 and the vertical rib 2). And having a length that sufficiently protrudes from the edge surface of the vertical rib 2, the both ends of the plate separator 10 are broken inside the casting surface when the concrete casting is completed (after the concrete is solidified). A through notch groove 12 is formed for cutting, and a through hole 13 through which a leg portion of the clip metal fitting 6 is inserted at a position corresponding to the position corresponding to the clip hole 7 formed in the vertical rib 2 of the concrete mold 1. Further, a tab 16 is formed by forming a square locking hole 14 at the outer end of the through hole 13.

That is, as shown in the embodiment of FIG. 4, it is recommended to form the ring-shaped tab (tongue piece) 16 by U-shaped slit tab 16 less molding or cutting. A notch groove 17 is formed in the base for facilitating bending, and the plate-like separator 10 can be temporarily fixed to the concrete formwork 1 by holding the slit tab 15 in the vertical rib 2. It becomes possible, and the latching hole 14 of the butterfly material clamp 20 described later is defined. This makes it possible to improve workability when constructing the concrete formwork 1 as a unit.

The portion of the plate separator 10 that is buried in the concrete formwork is provided with a binding hole 18 for binding and fixing with a wire to the reinforcing bar, and the central portion protrudes outward to receive the cone cup. In the vicinity of the end position of the end edge 19, a fracture notch groove 12 is formed in the vicinity of the end position of the end edge 19 in order to break the portion protruding from the concrete placement surface of the plate-like separator 10 after solidifying the concrete. Further, it is preferable that the both end edges 19 are formed by being slightly bent, so that the thickness of the plate separator 10 is not unnecessarily increased (without an increase in weight). Sufficient buckling strength as 10 is provided, and this angle of bending is used for stacking and stacking the plate separator 10 for storage, transportation and the like. Since there is required which does not cause, in particular, but not limited to, preferably set to approximately 60 degrees.

The cross-sectional shape of the plate separator used in Examples 1 to 4 is determined by the load acting on the mold, but the thickness at the notch groove is about 2 mm and the width is about 40 mm. The thickness is preferably about one third of the plate thickness.

Next, when the unitization of the concrete formwork is completed, the butter material is fixed to the concrete formwork 1. For this purpose, the butter material is fastened using the locking holes 14 of the plate separator 10 to fix the butter material. The metal fitting 20 is connected. The characteristic structure of the butterfly material clamp 20 is shown in FIG. That is, the butterfly material clamp 20 has a main body portion 21 formed by bending flat steel, and has a planar shape having a parallel fitting inlet 23 into which a hook-shaped curved head portion 22 and a taper pin 24 described later are inserted. It has a flat and substantially C-shape, and the tail portion is formed as an inclined portion 25 slightly downward so that the contact state between the oblique side of the taper pin 24 and the inner surface of the bent portion is in proper contact, and A protrusion 26 for preventing a seat plate metal member 27 from coming into contact with a later-described butterfly member is formed.

On the butterfly material clamp 20, a seat plate metal fitting 27 that abuts against the butter material and presses the butter materials 8 and 9 against the concrete mold 1 is effective for allowing the butterfly material clamp 20 to move up and down and back and forth. This is an indirect fitting for pressing a horizontal flap that is movable up and down and back and forth, in which an insertion port 28 is formed and bent reinforcing ribs are formed on both left and right edges of the insertion port 28.

The taper pin 24 associated with the butterfly material clamp 20 according to claim 1 is formed with a stopper 29 whose lower end edge (narrow width portion) is bent in a direction perpendicular to the taper surface, so that the taper pin 24 is prevented from falling off the fitting opening 23. Further, when the taper pin 24 is inserted into the insertion port 23 of the main body portion 21, an arc-shaped cutout portion 30 for facilitating the rotation operation of the taper pin 24 is formed. ing. By adopting such a configuration as the butterfly material fastening bracket 20, the seat plate bracket 27 and the taper pin 24 are integrally configured.

  Next, in order to explain the assembly procedure for unitizing the concrete form mentioned above, prepare the required number of concrete forms with the bar arrangement, and first build the first concrete form, The plate-like separator 10 is fitted into the vertical rib 2 of the frame 1, in other words, the groove 5 provided in the dam plate. First, a cone cup 31 that protects the fracture notch groove 12 from being buried in the concrete is inserted into the plate-like separator 10 from both sides, and in this state, the end surface of the cone cup 31 abuts against the sill plate of the mold 1. Fit into groove 5. The end portion of the plate-like separator 10 is in a state in which the outer portion protrudes from the vertical rib 2 from the locking hole 14, and more specifically, the root portion of the U-shaped slit tab 15 formed in the plate-like separator 10, that is, In other words, the length of the plate-like separator 10 is determined in consideration of such a state. In such a state, the tab 16 of the plate separator 10 is bent to temporarily fix the plate separator 10 itself to the vertical rib 2, and an adjacent concrete form is built while aligning the position of the plate separator 10. The formwork is fixed by a conventionally known clip metal fitting 6. As a result, the formwork is connected in a state where no gap is formed between the concrete formwork, and when the unitization is completed while repeating this procedure sequentially, it acts on the concrete formwork. Fix the butterfly material 8, 9 that supports the load.

  Various shapes such as round pipe, square pipe, and angle are used as the butter material. Pipe material is used in FIG. 1 (a), and angle material is used in FIG. 1 (b). An example is shown. The hook-shaped curved head portion 22 of the butterfly material clamp 20 is hooked in the locking hole 14 of the plate separator 10 and the butter materials 8 and 9 are arranged above and below the plate separator 10. The holding metal fitting 33 formed by bending the side butter material is prepared and supported. As shown in FIG. 1, the holding bracket 33 is sandwiched between the plate-like separators 10 and holds the protruding portion of the clip 6 in a backrest. The receiving portion of the lower butter material 9 is shaped like a butter material. It is preferable to form so as to tie together.

  Next, in the state where the butterfly material clamp 20 is hooked in the locking hole 14 of the plate-like separator 10, the taper pin 24 is pulled up until the stopper 29 part hits the U-shaped main body part 21, and further the notch part. 30 is rotated to position the phantom line in the figure, and then the seat plate metal fitting 27 is moved backward, and the lower butter material 9 is disposed on the holding metal fitting 33 described above, and then the seat plate metal fitting 27 is attached. In this state, the taper pin 24 is moved from the position of the phantom line to the position indicated by the solid line from the position of the phantom line in FIG. When the head is driven, the seat plate metal part 27 moves, and the butter members 8 and 9 are firmly pressed against the vertical ribs 2 of the concrete mold frame and fastened and fixed.

  Therefore, the plate separator provided in the vertical rib 2 of the concrete mold 1 is not attached as in the prior art when attaching the butter material that supports the load acting on the concrete mold, that is, the load generated when placing concrete. The work of tightening and fixing the butter material using the clip hole 7 using the dedicated butter material mounting bracket is omitted, so the workability is dramatically improved and the load acting on the concrete formwork is reduced. However, since the load acting on the intermediate rib 3 is transmitted to the plate separator via the butter material, a stable support structure is obtained. In addition, it is necessary to dismantle the concrete formwork after the cast concrete is solidified. However, by removing the taper pin 24 of the butter material fastening bracket 20, the butter member is tightened by the seat plate bracket 27. Therefore, by performing a procedure reverse to the above-described operation of fixing the butter material, the workability can be greatly improved since the removal can be performed in a short time.

  Furthermore, after the concrete curing period (after hardening), the concrete formwork 1 is disassembled, but dismantling is performed by a procedure reverse to the assembly procedure described above. After the removal of the formwork, the plate-like separator protrudes from the concrete placing surface, but it breaks from the break notch groove 12 formed in the separator as in the conventional case. That is, the separator projecting from the concrete placement surface is alternately and repeatedly bent to cause breakage due to plastic deformation and tear, thereby facilitating the removal operation of the cone cup 31. The dent of the corn cup left on the concrete casting surface is filled with mortar for the purpose of waterproofing or anticorrosion.

  In the above-described implementation, the main body portion 21 of the butterfly material clamp 20 is formed of flat steel, but round steel can also be used, that is, as shown in FIGS. The butter material fastening bracket 20 is bent in half so as to form a long and short leg with a gap between round steel bars, and the side portion of the other long leg portion 34 is bent by bending the tip portion 36 on one short leg side. The hook 39 is formed by bending the distal end of the long leg portion 34 into a substantially U shape. Further, the plate separator 10 is different from the above-described implementation in that the locking hole 14 becomes an arc-shaped locking hole 44.

A substantially U-shaped member 40 is fixed to the lower surface on the long leg 34 side by an appropriate means such as welding, and abutted with the vertical rib 2 of the concrete mold 1 on the lower upper surface of the U-shaped member 40. The groove 41 is formed, the opposite side is slightly bent upward, and the support plate 43 formed with the groove 42 into which the taper pin 37 is fitted is fixed. When the material fastening member 20 is locked in the locking hole 44 of the plate-like separator 10, the butter material fastening member 20 is prevented from rotating around the hook 39 by its own weight. Furthermore, a guide plate 46 is fixed to the inner surface of the fitting inlet 38 of the butter material fastening fitting 20 so as to assist smooth operation when the taper pin 37 is fitted.

  The taper pin 37 to be inserted into the insertion port 38 of the butterfly material fastening bracket 20 has a substantially triangular shape, and a stopper 47 for preventing the dropout from the insertion port 38 is formed on the tip triangular portion. An arc-shaped cutout groove 30 is formed on the upper side so as to engage with the round steel of the main body and rotate. When the butter members 8 and 9 are pressed and fixed using the butter material fastening bracket 20, a seat plate bracket 48 that presses the butter members 8 and 9 is mounted. In order to attach to the attachment 34 from the side, a transverse window 49 is formed at the center, and ribs 50 and 51 are formed at both ends, and the rib 50 is a taper pin 37. It is designed to act as a guide. However, when the butter members 8 and 9 are made of steel, the seat plate metal 48 directly presses the butter member 9 with the taper pin 37 described above, for example, as shown in FIG. It should be understood that this is not essential because it is possible.

  The case where the butterfly material clamp 20 is used will be described. As described above, the formwork is assembled in the same manner as the continuous construction of the concrete formwork 1. The hook 39 of the locking hole 44 of the plate-like separator 10 mounted between the molds and the hooks 39 of the material fastening fittings 20 is fitted, and the support plate 43 is brought into contact with and fixed to the vertical ribs 2 of the concrete mold 1. Next, the taper pin 37 is moved to the position of the imaginary line shown in FIG. 8 in order to engage the arc-shaped cutout portion 30 with the main body portion 35, and the butter material 9 disposed below is placed on the U-shaped member 40. Subsequently, the upper butter material 8 is disposed. At this time, if the butter material is only the lower part, it is placed on the upper part of the butter material fastening fitting 20 via the spacer 52, and then the seat plate fitting 48 for pressing the rear surface of the butter material 9 is attached to the main body portion 35. After the taper pin 37 is mounted from the side, the taper pin 37 is rotated and dropped into the fitting port 38, and its head is hit and fixed.

  Further, the example shown in FIG. 8B shows an example in which a steel angle material is used as the butter material, and the concrete formwork is fastened and fixed by the same method as described above.

  FIGS. 11 to 13 and FIG. 7 show another embodiment of the tightening structure according to the present invention, and the concrete formwork 1 has the same configuration as that of the first embodiment, so that the description thereof is omitted. To do. The plate-like separator 11 used in this embodiment has the thickness dimension of the structure to be constructed and the thickness of the concrete formwork (corresponding to the thickness of the concrete formwork) and the clip hole 7 drilled in the vertical rib. The through hole 13 is drilled at a position corresponding to the above, and a foldable tab 53 is formed at the end portion. Further, the buried portion is formed in the same manner as in the first embodiment.

  The body portion 55 of the butterfly material 20 is bent so as to form a slit gap 57 for inserting a taper pin 56, which will be described later, in a middle portion of a metal round bar, and one leg portion 58 is compared with the other. The planar shape is formed in a generally J shape by extending the end portion of the leg portion 58 in a direction perpendicular to the leg portion 58, and a locking portion 59 (fitting) that is inserted into the clip hole 7 is bent. In addition, a slit-like through hole 61 into which a fitting / tightening pin 60 is inserted is formed in the locking portion 59, and a butter material is fastened to the lower surface of the leg portion 58. In order to prevent the metal fitting 20 from rotating, a detent plate 62 which is in contact with the vertical rib 2 of the concrete mold 1 is fixed. The rotation stop plate 62 can be provided at an intermediate position of the leg portion 58 so as to abut against the vertical rib. Further, if the butter material fall prevention plate 54 is fixed to the upper portion of the leg portion 58, it is useful for safety measures. .

Further, the seat plate metal 63 and the taper pin 56 which are in contact with the butter materials 8 and 9 attached to the butter material fastening fitting 20 and press the butter material against the concrete mold 1 are of a general structure conventionally known.

The taper pin 56 inserted into the slit gap 57 has a substantially triangular shape, and is preferably connected to the seat plate metal fitting 63 by a chain or the like in order to prevent dropping.

The pin 60 for fitting and fastening to be fitted into the slit-like through hole 61 provided in the locking portion 59 is a substantially triangular flat plate shape, and a head portion 64 bent at the upper end portion is formed. A small hole 65 is formed in the head 64, and a support fitting 66 for supporting the butter material is hooked in the small hole 65. The support fitting 66 includes a hook-shaped top portion formed in a substantially L shape, a horizontal portion that supports the butter material 9, and a vertical portion that continues the horizontal portion. Although this support metal fitting 66 is not essential, it is recommended because the work of attaching the butter material 9 can be performed safely by providing the support metal fitting 66. In addition, the cone cup 31 in the figure is a cone cup for filling a waterproof material to prevent the separator from being buried in the concrete in which the fracture notch groove 12 portion of the separator is placed and for the rust prevention treatment of the fracture portion of the separator. It is.

    The advantage in this embodiment is that the plate-like separator 11 can be shortened, and there is an advantage that a portion to be broken at the time of demolding, in other words, a portion to be discarded can be reduced. As can be understood from the illustrated embodiment, the plate-like separator shape is a plate-like shape for fixing the butterfly material clamp 20 to the clip hole 7 formed in the longitudinal rib 2 of the opposing mold. It is sufficient that the length of the separator is formed so as to maintain the dimension required for the clip hole 7.

Next, in order to explain the assembly work procedure for unitizing the concrete formwork, the required number of concrete formwork is prepared with the reinforcement arrangement in the same manner as in the previous embodiment, and the first concrete formwork is first prepared. The plate-like separator 11 equipped with the cone cup 31 is fitted into the groove provided in the siding plate 4 of the concrete mold 1. A portion of the vertical rib 2 where the pinching portion 59 of the butterfly material 20 is inserted into the clip hole 7 and the pin 60 is fitted. The butterfly material clamp 20 is prevented from rotating. Next, the support member 66 made of butter material is mounted in the small hole 65 provided in the head 64 of the pin 60 for fitting and fastening.

  Next, the lower butter material 9 is temporarily placed on the support metal fitting 66 and the upper butter material 8 is placed on the main body portion 55, and then the seat plate metal fitting 63 is mounted on the main body portion 55. The lower butter material 9 is transferred to the receiving portion formed on the lower surface of the seat plate metal fitting, and then the taper pin 56 is inserted into the slit gap 59 provided in the main body portion 55, and the head is hit and driven. Fasten and fix the flaps 8 and 9.

  The cone cup 31 fitted to the separator 11 can also adopt various configurations. In the illustrated embodiment, a slit-shaped through hole 61 that is inserted into the separator 11 is provided at the bottom. A trapezoidal shape having a wall surface perpendicular to the bottom portion and an inclined outer casing, and a bent edge tab 32 is formed on the side in contact with the separator 11 at the opening end of the right-angle wall. When the mold is removed after installation and the cone cup 31 remaining on the casting surface is removed, it can be easily removed by hooking a bar on the bent edge 32 and peeling it off. .

  Moreover, the butterfly material clamp 20 shown in FIGS. 14 to 16 and FIG. 7 will be described. However, the concrete mold 1, the plate-like separator 11, and the taper pin 56 have substantially the same form as that used in the third embodiment, and therefore description thereof is omitted.

The main body 67 of the butterfly material clamp 20 is formed with a metal plate cut into a mold shape shown in FIG. 14 so that the metal plate is bent in a substantially U shape from the middle portion, and is sufficiently sensitive to sandwich the vertical rib 2 of the mold. The bent portion 69 is formed at an angle with which the back portion of the taper pin 56 comes into contact, and a clip hole 7 formed in the vertical rib 2 is used at the position of the head (tip portion). A through hole for fixing is formed. A substantially U-shaped support fitting 70 for supporting a butter material is fixed to one leg portion of the main body 68, and a groove 71 fitted into the vertical fitting and a taper pin 56 is inserted into the support fitting. And an L-shaped connecting rod 74 for fastening the butter material fastening bracket 20 to the vertical rib 2 of the mold frame. 74 is formed with a pin hole 76 through which a fixing pin 75 for fastening is inserted.

  Further, a taper pin 56 for inserting the butter members 8 and 9 is inserted into the slit gap 68 of the butter member fastening bracket 20. A flat cross section for guiding the taper pin and pressing the butter member is a co- A seat plate metal fitting 77 having a letter shape and bent at an upper portion of approximately 90 ° is fitted into the slit gap 68. Although not shown, it is preferable that the taper pin 56 and the seat plate metal member 77 are connected to each other by a chain in consideration of workability (prevention of dissipation) during use.

Further, the shape of the seat plate metal fitting 77 may be the shape of the seat plate metal fitting 48 shown in the second embodiment described above, but it is designed to be small in size so that it can be easily carried and carried at the construction site. Although this member is not necessarily required, it is an indirect member required for protecting the wear of the butter material. When this seat plate metal fitting 77 is omitted, the width dimension of the slit gap 68 for inserting the taper pin 56 is set to the thickness of the taper pin. Adjust according to.

The procedure for assembling the concrete form into a unit is almost the same as that of the above-described embodiment, and thus the description thereof is omitted.

Hereinafter, an embodiment of a concrete mold fixing and fastening support metal fitting according to the present invention will be described with reference to FIGS. 18 to 21 or reference numerals. However, the butter material fixing and fastening support metal fitting is for supporting the load received by the intermediate rib. A metal material is used for the member used for this, but the cone cup 79 is made of synthetic resin.

The plate separator 78 is formed by cutting a thick metal plate into a predetermined size as shown in FIG. 21 and bending the edge 80 at an obtuse angle to prevent buckling and receiving the cone cup 79 in the buried portion of the concrete. This bending angle is not particularly limited because it is not necessary to cause trouble in stacking and packing the plate-like separator 78 for storage, transportation, etc., but it is about 45 degrees. In addition, the folded fore edge accepts the cone cup 79, and this position becomes the cross-sectional defect fracture portion 81, and the shaft can be rotated (twisted) to be cut off. When the separator 78 is a precious metal, the cone cup 79 is not required, and thus the cutout position is an effective dimension of the structure to be built. To form a locking projections 83 in both wings of the order.

The butter material fastening support fitting is a connecting plate 89 in which a metal plate having the same thickness as the plate separator 78 is about 1.5 times the width of the plate separator 78 and the length is cut about three times this. An insertion receiving port 84 for receiving the above-described locking projection of the plate-like separator is formed in the plate tip, and a clip hole 85 for fitting the edge rib 2 is formed in the retracted portion, and the retracted portion will be described later. A flat steel plate is cut into a predetermined length on a connecting plate 89 formed with an elongated slide through hole 87 required to prevent the cover socket 86 from coming off, and a receiving port for insertion of the taper pin 37 is formed by bending in parallel from the center portion. In consideration of the space required for fastening the butter material, it is sandwiched and welded or welded by the fastening member 82. The tail of the fastening member 82 is formed in accordance with the angle of the back of the taper pin 37.

The above-described cover socket 86 is a metal fitting that fits the engagement protrusion 84 of the plate-like separator into the insertion receiving opening 84 of the connecting plate 89 and fixes the periphery of the fitting, and has a rectangular shape. A rod pin 92 for preventing disengagement is inserted into the slide through hole 87 and fixed to the cover socket, and a fool hole is drilled on this side surface for insertion into the clip hole 85 of the edge rib 2. Also, on the lower side of the lower part, a horizontal butterfly support / body support member (arm) 90 is fixed by welding or welding, and a short belt plate for holding the body support and the vertical of the taper pin in the horizontal buttery reception part. A metal separate plate (pressing plate) 91 having grooves 88 formed in the terminal is integrated by welding or welding. The horizontal butterfly receiving / body support member 90 also has a structure for preventing the movement of the cover socket when the horizontal butterfly material is fixed.

The cone cup 79 is formed by thickening the bottom of the truncated cone-shaped cup to form an insertion port for the plate-shaped separator. This is also achieved by rotating the axis of the unnecessary portion of the plate-shaped separator 78 after solidifying the concrete. It is a divertable form in which the cone cup is naturally removed at the same time as the separator is cut off by rotating together.

The concrete formwork assembling procedure is as follows: the first concrete formwork is built, the plate-like separator 78 through which the cone cup 79 is inserted and the horizontal butterfly fastening support metal body are connected, or the groove of the concrete formwork plate 4 When inserted into the drill hole from the side and sandwiched between the concrete cup 79 and the cover socket 86 and then temporarily fixed, the second concrete mold 1 is installed, and the clip 6 is fitted into the clip hole 7 of the edge rib 2 to form a plate separator. At the same time as 78 is fixed, the plate surface of the concrete mold 1 and the vertical position adjustment are naturally fixed. While repeating this, the butter materials 8 and 9 are arranged, the taper pin 37 is dropped and the pressure is arranged. The straight line of the formed formwork is held and the load of the intermediate rib 3 is supported. However, when the butter material is only the lower part, a separate metal fitting (spacer) is provided on the upper part. ) 52 to bite

  After the concrete curing period (after solidification), the concrete mold 1 is removed in the reverse procedure of assembly, but the plate-like separator 78 remains protruding from the concrete surface on the concrete placement surface. The unnecessary portion of the separator 78 is rotated and broken by using a tool by human power, and particularly preferably, the unnecessary portion may be broken by rotating the unnecessary portion using an impact wrench. The cone cup 79 can also be peeled off from the concrete surface and collected at the same time, and workability can be improved. The cone cup 79 removed together may be collected in a timely manner and reused.

  What is characteristic in this embodiment is that the separator is provided with a thickness that maintains the strength necessary to withstand the load of the placed concrete acting on the separator, while reducing the width, thereby reducing the width of the concrete. The broken portion 81 of the plate-shaped separator 78 can be made by rotation (twisting), and in addition, the cone cup 79 can be removed simultaneously by this twisting. Further, if the protruding portion of the separator is removed in advance, the mold removal work is facilitated.

  Hereinafter, embodiments of the concrete mold fixing and fastening support metal fitting according to the present invention will be described with reference to FIGS. 21 to 23 and FIGS. 24 and 25 or reference numerals. And a one-piece structure. In addition, a metal material is used as a member used for the concrete mold fixing and fastening support bracket, and a synthetic resin material is used for the cone cup 98.

When the vertical rib 2 is made of metal, this concrete formwork is turned to the plate separator 93 and positioned on a slat plate in which an arcuate cut groove 95 is cut at a dimension position where the tool can be inserted. Or, if the vertical rib 2 is fixed with bolts, etc., and is made of wood (crosspiece), the cut groove 94 of the vertical rib 2 is turned and cut to a size that allows insertion of a tool, and the insertion portion of the plate-shaped separator 93 has an arc shape. Are fixed with screws, bolts, or the like to face the end face of the slat plate in which the kerf 95 is formed.

The plate-shaped separator 93 has the same form as that of the fifth embodiment with respect to the concrete buried portion. On the outside from the concrete surface, a slit-shaped insertion effective for pressing the taper pin 56 is formed by sandwiching the concrete mold 1, butter material 8, 9 and the seat plate metal fitting in the cone cup 98. Thereby, it becomes an integral structure with the butterfly material clamping support portion.

Since the cone cup 98 used for this has the same form as that used in Example 9 described later, the description thereof is omitted.

Further, when the edge rib 2 of the joint portion is a wooden pier, the seat plate metal piece 56 and the taper pin 63 are the same as those used in the above-described third embodiment, and the description thereof is omitted.

Furthermore, when the vertical rib 2 of the joint portion is a metal L shape, the metal plate is bent into an L shape as shown in FIG. 24 and FIG. 25 to receive the butter material at the lower portion and the vertical rib 2 is sandwiched. Therefore, a sandwiching and seating plate metal fitting 96 is used in which a groove contact opening is formed in a substantially concave curved portion at the portion contacting the vertical rib 2.

As for the concrete formwork assembly work procedure, when the edge rib 2 of the concrete formwork is a wooden pier, the first concrete formwork 1 is built and the cone cup 79 is installed in the arc-shaped cut groove 95 shown in FIG. The second sheet-like separator 93 is positioned, and the second concrete form 1a is built and connected with a nail rod 97 or the like, and this procedure is sequentially repeated to support the load members 8 and 9 that support the load acting on the concrete form. Fix it.

Further, when the edge rib 2 is a metal L-shape, the plate-shaped separator 93 in which the cone cup 79 is mounted is positioned in the arc-shaped cut groove 95 of the baffle plate in which the first concrete form 1 is built, The second concrete mold 1a is built and connected by using the clip metal fitting 6, and the butter members 8 and 9 supporting the load acting on the concrete mold are fixed while sequentially repeating this procedure.

As for the formwork dismantling, after the concrete curing period (after hardening), the concrete formwork 1 is demolded in the reverse procedure of assembly in the same manner as in Example 6, but the difference from Example 6 is that After removing 9, the unnecessary part protruding from the concrete surface of the plate-like separator 93 is cut off using a turning tool 146 while leaving the formwork left. As a result, the releasability of the formwork is remarkably improved, so that disassembly is facilitated, and the holding property of the concrete formwork is also improved.

Hereinafter, an embodiment of a concrete mold fixing and fastening support metal fitting according to the present invention will be described with reference to FIGS. 27 to 30 or reference numerals. The plate separator 101 has an integral structure with a butter material fastening support portion. Moreover, although the metal material is used for the member used for the concrete mold fixing fastening support bracket, the cone cup 98 has the same form as that used in Example 9 which will be described later, so that the description is omitted. To do.

This concrete form fixing / fixing support metal fitting is difficult to use the horizontal butter material because the space between the concrete frame surface and the temporary scaffolding, etc. is narrow and the work space cannot be secured in the concrete formwork assembly work such as the outer wall. Alternatively, the concrete formwork 1 has a structure in which the intermediate rib 3 is used sideways and is fixed to the L-shaped edge rib 2 with bolts or welding to eliminate the need for the horizontal butter material 8 and 9 so that it can be used when impossible. It is.

The sandwiching seat plate 110 is a metal fitting for fixing the intermediate rib 3 with a bolt. The intermediate rib 3 is used when a square pipe or a pier is used.

Since the plate-like separator 101 does not use a butter material, the concrete buried portion including the cone cup 98 is the same form as the plate-like separator used in Example 6 above, and the description is omitted. The fastening portion of the concrete mold 1 has a slit-shaped through-hole 107 for inserting the taper pin 102 at a position where an effective dimension for sandwiching and pressing the mold frame and the pressure-resistant seating metal fitting 104 is secured. There is.

The pressure bearing plate metal fitting 104 described above is formed in a substantially U-shaped flat cross section so that the edge rib 2 facing the metal plate of a required dimension as shown in FIG. A circular insertion port 103 into which a turning tool 146 can be inserted in consideration of rotating and twisting unnecessary portions of the separator 101 is drilled, and fixing holes 105 through which bolts and the like are inserted are drilled on both side surfaces.

The taper pin 102 has a general form in which the taper pin 56 used in the third embodiment is reduced in size by cutting a metal plate into a taper shape. The taper pin 102 is used to fasten the vertical rib 2 or the butter material via the pressure bearing plate metal fitting 104.

The concrete formwork assembling procedure is as follows. After mounting a sheet material for placing the concrete formwork 1, the first concrete formwork 1 is installed, and the cone cup 98 is inserted into the arc-shaped cut groove 95 shown in FIG. Is positioned, the second concrete mold 1a is built, the pressure-resistant seating plate metal fitting 104 is tightly attached to the edge rib 2, and the taper pin 102 is attached to the insertion port 107 of the plate-like separator 101. The unitization of the concrete formwork is completed by repeating the insertion and pressurization sequentially. Further, by using the clip hole 7 of the edge rib 2 of the fixing rib 105 edge rib 2 of the pressure bearing plate metal fitting 104, the pressure bearing plate metal fitting 104 can be moved to the upper floor while holding the unit mold frame by fixing it with bolts or the like. It becomes easy.

The work procedure for dismantling the concrete formwork is as follows. After the curing period of the placed concrete (after curing), the taper pin 102 is removed, and the tool 151 is inserted and fitted into the plate-like separator 101 insertion port 103 of the pressure-resistant seat plate metal fitting 104. Then, by removing the unnecessary portion of the separator protruding from the concrete surface by rotational twisting, the mold can be easily removed and the cone cup 98 is automatically peeled off. At this point, the unitized formwork can be easily slid to the upper floor (replacement movement), and if it does not slide (replacement movement), the pressure-resistant seat plate metal fitting 104 is removed and demolded to the extent that it can be carried out. .

Hereinafter, an embodiment of a concrete mold fixing and fastening support metal fitting according to the present invention will be described based on FIGS. 32 to 36 or reference numerals, but the plate separator 111 has an integral structure with a butterfly material fastening support part. Moreover, although the metal material is used for the member used for the concrete mold fixing fastening support bracket, the cone cup 98 has the same form as that used in Example 9 which will be described later, so that the description is omitted. To do.

The description will be made on the assumption that the vertical ribs 2 of the concrete formwork used for this are made of a wood material or a metal material cavity, and the siding plate 4 is a wood plywood or a synthetic resin plate.

The plate-shaped separator 111 has a cross-sectionally broken fracture portion in which both edges are cut off for cutting and cutting, in order to insert a receiving plate 113 for receiving the cone cup 98 into a concrete buried portion by cutting flat steel into a required dimension. 81 is engraved, the formwork crest 4 is fitted to the outside, a latching hole 119 for attaching the butter receiver 115 is drilled, and the taper pin 56 for pressing the butter members 8 and 9 is inserted further outward. By engraving the opening 117, the plate separator 111 itself is integrated with the butterfly material tightening support portion.

The cross-sectional defect fracture portion 81 described above will not be described since it has a common shape.

In order to lock the cone cup 98, the receiving plate 113 used for this is engraved with a groove opening that fits into the cross-sectional defect portion 81 of the plate-like separator 111 in the metal plate, and can be bent to prevent detachment. The slit tab 114 is engraved.

Further, the cone cup 98 used for this is formed in a truncated cone shape, and is provided with a slit-shaped through-hole 100 having an arc-shaped depression along an axial center through which the plate-shaped separator 111 is inserted. A flange-like projecting bearing 99 that fits into a groove 95 formed in the slat plate 4 is formed on the contact surface of the slat plate.

The butter metal fitting 115 used for this purpose is for preventing the plate-like separator 111 from coming off and receiving the horizontal butter material 9 by disassembling the barrier plate, and this butter metal fitting 115 is made of a metal round bar as shown in the figure. The end portion 124 is formed in a taper shape so as to facilitate insertion of the tip portion into the locking hole 119 of the plate-shaped separator 111, and the end portion 124 is formed in a substantially rectangular shape to prevent the horizontal butter material 9 from slipping down. Protrusions are formed.

Since the seat plate metal fitting 63 and the taper pin 56 used for this are the same as those used in the sixth embodiment, the description thereof is omitted.

The concrete formwork assembly procedure is as follows. When the vertical ribs 2 of the concrete formwork are wooden piers or metal hollow pipes, the first concrete formwork 1 is built and the cone cup 95 is inserted into the arc-shaped kerf 95. When the plate-like separator 111 to which 98 is attached is positioned and the insertion portion of the butter metal fitting 115 is inserted into the retaining opening 119, the separator is clamped to the siding plate 4 and then connected to the second concrete formwork 1a is connected with a built-in nail rod 118 or the like, and this is sequentially repeated, but the butter materials 9 and 8 are arranged above and below the separator, and the taper pin 56 is inserted and pressurized to support the concrete formwork to be fixed. .

In this case, the plate-like separator 111 can be used not only at the joint part where the concrete mold is connected but also at the center part or at a required position.

As for the formwork dismantling work, the concrete formwork 1 is removed in the reverse procedure of the assembly in substantially the same manner as in Example 6, but the difference is that a butter metal fitting 115 for preventing the falling of the butter material 9 is attached. Therefore, it is to improve the safety of work.

Hereinafter, an embodiment of a concrete mold fixing fastening metal fitting according to the present invention will be described with reference to FIGS. Further, the plate-like separator 111 has an integral structure with the butterfly material clamping support portion. Moreover, a metal material is used for the member used for a concrete form-fixation fixation support metal fitting.

The vertical ribs 2 of the concrete mold used for this will be explained on the premise that the siding board 4 is formed of a wooden plywood or a synthetic resin board with a metal material having the shape of an L shape or a square pipe.

The plate separator 111 is substantially the same as that used in the eighth embodiment, and the difference is that the latch 119 for latching the butter metal fitting 115 is not required.

Since the receiving plate 113, the cone cup 98, and the taper pin 56 used for this are the same as the products used in the ninth embodiment, the description thereof is omitted.

The sandwiching and catching metal fitting 120 for connecting the concrete formwork 1 is a fitting in which a metal round bar having a diameter of about 13 mm is bent upward from the butter material placement portion and inserted into the clip hole 7 of the vertical rib 2. The main shaft portion 116 of the sandwiching butter receiving metal fitting 120 is formed as shown in FIG. The butter material placing portion is kept horizontal by contacting the vertical rib 2. Further, the end portion 134 forms a protrusion that is bent slightly upward to prevent the butter material 9 from falling.

A slit-shaped through-hole 121 for inserting the fastening pin 122 is formed at the tip of the fitting shaft portion 123.

The clamping pin 122 is formed by cutting and forming a flat steel plate having a thickness of 4 mm, a width of 25 mm, and a length of 65 mm into a slit-like through-hole 121 so as to be tapered. Further, in consideration of workability (prevention of dissipation), it is preferable to connect the fastening pin 122 and the sandwiching butterfly fitting 120 with a thin wire rope or the like.

The feature of this embodiment resides in the sandwiching and receiving butter receiving bracket 120 in which the portion for sandwiching the vertical ribs of the concrete mold and the butter receiving portion are integrated.

The concrete formwork assembling procedure is to insert the first concrete formwork 1, insert the plate-shaped separator 111 with the cone cup 98 set in the arc-shaped cut groove 95, and use scissors (not shown). Next, the second concrete form 1a is erected, and the sandwiching and butterfly fitting 120 is inserted, and the clamping pin 122 is inserted and continuously provided. While repeating this procedure in sequence, the butter members 8 and 9 that support the load acting on the concrete formwork are fixed.

The concrete mold 1 used for this will be described on the assumption that the vertical rib 2 uses a wood material or a metal material cavity, and the support plate 4 uses a wood plywood or a synthetic resin plate.

The plate-like separator 125 is substantially the same as that used in the ninth embodiment, except that a butter metal fitting 130 is attached to the outside of the concrete formwork plate 4 and a connection pin 131 is inserted to the outside. A slit-like connection receiving port 126 for engraving is provided.

Batter material tightening support metal fitting main body 127 connected to plate-like separator 125 is formed by cutting a metal strip having a thickness of about 4.5 mm and a width of about 16 mm into a required size, and sandwiching the upper and lower sides of the separator from the center to form two layers. In order to fit the bent end portion to the slat plate 4, a bearing portion 113 cut in a hook shape is formed, and a kerf 142 to which a round washer 141 for receiving the slat plate 4 is fitted behind is formed. A slit-shaped through-hole 129 for connecting the plate-shaped separator 125 with a dimension for fitting the butter receiving metal fitting 130 is secured on the rear side, and the butter materials 8 and 9 on the rear side are pressed and fastened. For this purpose, a slit-shaped through hole 128 for inserting the taper pin 56 which is effective is formed, and the upper and lower members are squeezed and squeezed in order to facilitate the operation of the taper pin 56 at the rear end portion 132.

The above-described butter receiving bracket 130 is formed by cutting a flat steel having a thickness of about 4.5 mm and a width of about 16 mm into a required size, and bending an insertion portion 143 to be attached to the butter material tightening support bracket main body 127 into a rectangular ring shape. In order to place the butter material 9 on the lower side, a butter material receiving portion that is bent horizontally is formed, and this end portion 135 is slightly bent upward to prevent the butter material 9 from falling. Protrusions are formed. The use of the butter metal fitting 130 is for receiving the butter material 9 and for preventing the fall, and is preferably used at an appropriate location. Further, the location where the butter metal fitting 130 is not used is shown in FIG. The seat plate metal 63 and the taper pin 56 shown in FIG.

Since the receiving plate 113 used for this is the same as that used in the ninth embodiment, and the cone cup 79 is the same as that used in the fifth embodiment, the description thereof is omitted.

In addition, the connection pin 131 used for this is formed by tapering the tip of a flat steel cut into a thickness of 4 mm, a width of 25 mm, and a length of about 80 mm, so that the operation of the connection pin 131 is smooth.

The concrete mold assembly work procedure is as follows. The first concrete mold 1 is built, the plate-like separator 125 in which the cone cup 79 is set in the arc-shaped cut groove 95 of the baffle plate 4 is positioned, and the butter material tightening support metal fitting body The part 127 is inserted and the connection pin 131 is inserted and pressurized, so that the separator is clamped to the dam plate. Depending on the situation, the separator is temporarily attached using a clamp (not shown) and then connected to the second sheet. The concrete mold 1a is connected with the built-in nail bar 118 or the like, and this procedure is sequentially repeated to fix the butter materials 8 and 9 that support the load acting on the concrete mold.

In this case, the plate-like separator 125 can be used at the center or an appropriate position, not necessarily the joint where the concrete mold is connected.

As for the formwork dismantling, after the concrete curing period (after hardening), the concrete formwork 1 is demolded in a procedure almost the reverse of the assembly work described above.

Hereinafter, an embodiment of a cone cup according to the present invention will be described based on FIG. 45, FIG. 46 or reference numerals. Further, the cone cup 136 used for this can be used in place of the cone cup 79.
