Description

  The present invention relates to a concrete mold.

The structure of the formwork using the conventional pier fixed formwork for concrete molding will be described with reference to FIGS.
The pier fixed formwork is a lavan plywood (sometimes referred to as a control panel) or a synthetic resin plate 2 or the like. It is fixed. As for the connection of the pier fixed formwork, the piers 67 fixed to the edges of the adjacent pier fixed form frames are butt-joined, and a nail 74 is driven into and fixed to the pierced crosspieces 67 and connected to a desired position. By inserting the screw portions 55 of the cones 54 to be screwed into the both ends of the round separator 53 into the separator holes 57 provided in the connected fixed board frame 2, the screw portions 55 of the cone 54 excluding the barrier plate 2 are inserted. The horizontal butterfly material fastener 69 (also referred to as a foam tie) is screwed and fixed, and the horizontal butterfly material 14 that supports the back portion of the fixed frame frame is disposed above and below the horizontal butterfly material fastener 69, In general, a method of tightening and fixing the horizontal butterfly material 14 by rotating a nut 19 screwed through a seating tool 10 to be inserted into the threaded portion of the horizontal butterfly material fastener 69 is generally used.
However, in this construction method, after the fixed frame 67 fixed mold frame on the opposite side is arranged, the screw portion 55 of the cone 54 screwed to the round separator 53 fixed to the fixed frame 67 fixed mold frame and the opposite fixed frame mold Aligning with the separation hole 57 provided in the frame, the piercing frame fixed plate 2 opposite to the screw portion 55 of the cone 54 is sandwiched, and the horizontal butterfly material fastener 69 ( This is also called a foam tie.) The screw portion 55 of the cone 54 that is fixed to the crosspiece fixed form frame arranged on one side is fixed because a plurality (about 5 to 6) of screw portions 55 are fixed. It is difficult to match with a plurality of (about 5 to 6) separator holes 57 provided on the side fixing frame.
Also, in the part dismantling of the formwork, the place where the lever bar cannot be hooked has a problem that the formwork may be damaged by forcibly removing the crosspiece and forcibly inserting the tip of the lever bar into the joint between the slats 2 .
Further, when the conventional round separator 53 is used, if the tightening force of the nut 19 screwed into the thread portion of the lateral butterfly material fastener 69 becomes excessive, the swash plate 2 becomes the lateral butterfly material 14 as shown in FIG. There is a drawback that it is pulled to the side and deformed into a curved shape.

FIG. 19 is a perspective view showing an example of a state in which the connecting portion of the conventional pier fixed formwork is connected with a nail, and the opposite hands are obtained by holding the piers 67 fixed to the edge of the fixed pedestal frame with one hand. A method of driving the nail 74 with a hammer is common. However, in this method, due to vibration when the nail 74 is driven with a hammer, the mutually connected piers 67 are slightly moved in different directions, and the slats 2 are likely to be mistaken or stepped. For this reason, a connecting tool called a vise-like crosspiece clamp (PAT) is on the market (refer to page 71 of Non-Patent Document 1 for a crosspiece clamp).
In addition, with regard to the connection of the fixed frame frames to be connected, in the work of driving and fixing the nails 74 at the same time as performing the level and face-to-face adjustment between the fixed frame frames 67 of the fixed frame type, an experienced technician is required, There is a difficulty in securing employment of workers.
Furthermore, since the pier 67 serving as the skeleton of the pier fixed formwork is made of wood, it has a disadvantage that it is bent by drying and the strength becomes unstable due to deformation such as torsion or nodes.

  Hereinafter, an example of a conventional concrete forming mold and its connecting tool will be described with reference to FIGS. 18 and 20 to 22.

In the H joint 70 shown in FIG. 18, a partition portion 71 and a fixing portion 72 are integrally formed of a steel plate of about 1 mm, and a nail hole 73 is provided in the fixing portion 72.
This H-joint 70 is used for the purpose of connecting and mating the panels 2 of the panel or the synthetic resin plate having a thickness of about 12 mm. However, since the accuracy of the seam portion where the plates 2 are connected to each other is inferior, There are disadvantages that are not suitable.

20 and 21 are reference views showing a connection state in which a clip metal fitting 75 is used in a conventional edge rib 76 fixed mold, and the rib fixed mold is a cue such as a panel (Lawan plywood) or a synthetic resin board. A substantially L-shaped edge rib 76 is fixed to the edge of the back surface of the plate 2 with a countersunk bolt 77, and a vertical butterfly material is disposed and fixed to the middle part.
The edge rib 76 fixed formwork is mainly used for formwork of residential buildings, but in Japanese residential buildings, since the wall and the slab (floor) on the upper floor are integrally constructed, after concrete casting However, although the formwork dismantling material is moved to the upper floor, the slab (floor) on the upper floor becomes an obstacle, and there is a difficulty that heavy machinery cannot be used for unloading work. Therefore, it is required to make it lighter by hand.
The clip metal fitting 75 includes an insertion shaft portion 79 that is inserted into a hole between the edge ribs 76 to be connected by processing a bar having high rigidity such as iron, and an arm 80 that extends perpendicularly from the insertion shaft portion 79. The arm 80 is formed of a generally curved holding portion 81 formed integrally with the arm 80.
As a result, the insertion shaft portion 79 is inserted in a state where the arm 80 of the clip metal fitting 75 is horizontally inserted into the connection hole between the edge ribs 76 to be connected, and the holding portion 81 supported by the arm 80 extending at a right angle from the insertion shaft portion 79 is provided. The hammer is struck with a hammer and the edge ribs 76 are sandwiched with excessive strength. Therefore, as shown in FIG. 21, there is a difficulty that the gap between the edge rib 76 and the edge rib 76 cannot be maintained and is deformed.
In addition, if the sandwiching width 82, which is the thickness dimension of the sandwiched object, is too wide, a gap is formed between the connecting board 2 and the connecting board 2, and the liquid portion of the concrete (cement nose) protrudes from the gap and protrudes from the concrete surface. There is a difficulty that can form burr.
Further, a retaining hole 78 for a screwdriver or the like is provided on the head of the countersunk bolt 77 used for fixing the weir plate 2 and the edge rib 76, and once used, the retaining hole 78 is filled with concrete, and the weir plate 2 There is a drawback that it becomes difficult to remove the flat bolt 77 by rotating the flat bolt 77 and the nut together at the time of replacement. Therefore, there is a difficulty that the countersunk bolt 77 that has been removed cannot be reused.

FIG. 22 is a perspective view showing a connection state of the resin mold 92 and its mold connector, and the mold connector 83a shown in FIG. 22 (22a) is inserted into the connection hole 86 between the edge ribs 85. The arm 91 extends from the insertion shaft portion 87 at a right angle, and the holding portion 90 is formed integrally with the arm 91.
About this, in order to pinch the front-end | tip part of edge ribs 85, a clearance gap may be made in the part 84 part of resin-molding molds to connect, Therefore, as shown in FIG. There has been proposed the formwork coupler 83b in which a male screw is formed at the distal end of the insertion shaft portion 88 to be inserted into the coupling hole 86, and is tightened and pressed with a nut 89 to close the gap between the baffle plates 84 (for example, (See FIG. 4 of Patent Document 5.)
In addition, since the slat plate 84 and the edge rib 85 are formed integrally with the resin molding die 92, there is a difficulty in that the severing slat plate 84 cannot be replaced.
Further, the mold connecting tool 83b takes time and labor for screwing the nut 89, and when disassembling the mold after solidifying the concrete, the male screw at the tip of the insertion shaft portion 88 and the connecting hole 86 between the edge ribs 85 are provided. However, since it is difficult to slip due to friction, it takes time for the extraction work, and there is a difficulty that the screw portion is damaged due to friction between the connecting hole 86 of the edge ribs 85 and the screw portion at the tip of the insertion shaft portion 88.

  The butter material that supports the back of the formwork includes a square pipe such as a steel pipe, a vinyl chloride pipe, and an aluminum pipe, and generally a single pipe of 48.6φ is mainly used. However, recently, square pipes such as light PVC pipes and aluminum pipes have attracted attention.

Issued by Marui Construction Parts Catalog No.9 / Marui Sangyo Co., Ltd. Product catalog No.3, formwork, Okabe Co., Ltd.

The present invention has been made in view of the above-described points. Conventionally, an edge rib is fixed to the back surface of a lauan plywood having a thickness of about 12 mm (hereinafter also referred to simply as a panel) or a synthetic resin board. As shown in FIG. 2 to FIG. 4, the panel form mold 1 of the present application, which is slightly different from the edge rib fixed mold form, has protrusions on both outsides of the adjacent panel form mold 1 edge ribs 3. 20 and FIG. 21, which is a formwork connecting tool of FIG. 20, or the formwork connecting tool shown in FIG. 22 cannot be used.

In a conventional formwork such as a pedestal fixed formwork or an edge rib fixed formwork, there is a problem that there is not enough space between connecting parts that connect adjacent formwork, so that the insulator bar cannot be inserted.

Since concrete structures (frames) in Japanese residential buildings are constructed with the wall and the slab (floor) directly above the floor, when the formwork material after dismantling the formwork is moved to the floor directly above, Since the slab (floor) becomes an obstacle and it is difficult to use heavy machinery, the panel form 1 is moved by hand, and it is required to reduce the weight of the panel form 1 as much as possible.
In addition, in the conventional edge rib fixed formwork, since the conventional countersunk head bolt is used to fix the sill plate 2 and the edge rib, concrete is filled into the retaining holes 78 of the countersunk head bolt driver, etc. once used. By doing so, it becomes impossible to hook a screwdriver or the like that stops the countersunk head bolt from rotating. For this reason, there has been a difficulty that the countersunk head bolt is difficult to be removed or tightened by turning the countersunk head bolt and the nut together (idle rotation).

The present invention has been made in view of the above-described points, and a mode for solving the above-described problems will be described with reference to FIGS. In addition, the one-side drawing of the symmetrical part which does not interfere with description is abbreviate | omitted.
The board 2 constituting the panel form 1 is a lauan plywood (hereinafter sometimes referred to simply as a panel) having a thickness of about 12 mm or a synthetic resin board, and the edge rib 3 fixed to the board 2 is used. Presupposes the use of metal or synthetic resin.
Furthermore, it is assumed that the material used for the connector 6 that connects the adjacent panel form frame 1 edge ribs 3 to each other is made of metal or synthetic resin.

The panel form frame 1 is used for inserting the fixing bolt 5 into the fixed side 46 of the forming material provided with the protruding portion 4 on the inner corner surface side of the end portion of the connection side 47 having a substantially L shape composed of the fixed side 46 and the connection side 47. The holes 43 are provided at regular intervals, and the edge ribs 3 in which the holes 44 for inserting the connector 6 guide pins 21 are provided at regular intervals on the coupling side are fixed to the coupling portion of the dam plate 2. Accordingly, the protrusion 4 is provided on the inner corner surface side of the end portion of the connection side 47 that is substantially L-shaped, so that the section modulus is increased and the lightened edge rib 3 is fixed, so that the panel form 1 is lightened. However, since there are the protrusions 4 protruding on both outer sides of the edge ribs 3 to be connected, the conventional connector cannot be used, and the connector 6 of the present application is used.
Further, as shown in FIG. 2, a gap is provided between the edge ribs 3 in order to insert the plate separator 7 between the panel form frame 1 edge ribs 3 and to facilitate disassembly of the formwork.

As shown in FIG. 8, the fixing bolt 5 for fixing the panel form frame 1 sill plate 2 and the edge rib 3 has a head portion 38 having a substantially conical dish shape, a body portion 39 having a substantially truncated pyramid wedge shape, and a screw portion 40 having a truncated cone shape. A male screw that is screwed into the nut 41 is integrally formed. As a result, the fixing bolt 5 is inserted into a hole 42 provided in advance on the dam plate 2 and the head 38 of the fixing bolt 5 is struck with a hammer or the like so that the head portion 38 and the body portion 39 are formed. Since the fixing bolt 5 and the nut 41 rotate together in order to bite and fix on the weir plate 2, the rotation (idle rotation) in which the fixing bolt 5 and the nut 41 rotate together is eliminated.
Therefore, as shown in FIG. 15, after the concrete is solidified, the connecting tool 6 is removed, and the nut 41 for fixing one edge rib 3 is rotated with the panel form frame 1 retaining plate 2 left, and the edge rib 3 is removed. The tip of the insulator bar 58 is inserted into the hole 44 for inserting the connector 6 guide pin 21 provided on the other edge rib 3, and the remaining panel form frame 1 slat plate 2 is used as a fulcrum for the reaction force. According to the principle of the insulator, the panel form frame 1 and the board 2 are easily peeled off (demolded).

As shown in FIG. 7, the connecting tool 6 is inserted into a guide pin 21 to be inserted into the hole 44 between the edge ribs 3 to be connected, and an insertion hole 23 for inserting a receiving pin 29 provided at the tip of the guide pin 21. A receiving pin 29 to be inserted and a screw bolt 26 screwed to the rear end portion via the movable member 25 are configured.
As a result, the connecting tool 6 guide pin 21 is inserted into the hole 44 between the adjacent panel form frame 1 edge ribs 3, and the receiving pin 29 is inserted into the insertion hole 23 for inserting the receiving pin 29 that appears. The movable member 25 advances by inserting and rotating the screw bolt 26 screwed to the rear end portion of the guide pin 21 via the movable member 25, and presses and holds the edge ribs 3 together. That is, there is a feature that the screw bolt 26 screwed to the rear end portion of the guide pin 21 via the movable member 25 is pressed and clamped by rotating.
Further, there is a feature that the movable member 25 is moved by rotating the screw bolt 26 so that the clamping range 25s (clamping margin) can be narrowed widely.
Further, when the receiving pin 29 inserted into the insertion hole 23 for inserting the receiving pin 29 at the tip end portion of the guide pin 21 abuts against the edge rib 3, the guide pin 21 and the screw bolt 26 rotate together. ), The screw bolt 26 can be tightened with one hand using a screwdriver such as a screwdriver.

As shown in FIG. 5, the horizontal butterfly material fastener 8 is fitted with a fitting member formed by bending a metal plate of a desired size into a substantially unequal side L-shape consisting of a fitting side 30 and a connecting side 31. A fitting body 15 having a hole 44 through which the guide pin 21 is inserted in the side 30 and a hole 16 for inserting a connecting bolt 18 for connecting a shaft bolt 17 called a foam tie (registered trademark) to the connecting side 31 is formed. The bolt insertion hole 16 and the female screw provided in the base portion 56 of the shaft bolt 17 are matched with each other and connected by the connecting bolt 18.
As a result, the connecting tool 6 guide pin 21 is inserted into the hole 44 for inserting the connecting tool 6 guide pin 21 provided between the adjacent panel form frame 1 edge ribs 3, and the connecting tool 6 guide that appears as a result of the insertion. The pin 21 can be used by being fitted to the tip.

The plate separator 7 is formed of a metal material or a synthetic resin material with holes for inserting guide pins 21 at both ends of a strip-shaped separate member having a desired length, and is positioned inwardly (wall-centered) from the hole. Specifically, the groove of the cross-sectional defect portion 12 that makes it easy to bend and cut at a position slightly inward (wall center) from the concrete surface side of the panel form frame 1 siding plate 2 is approximately V-cut. To form.
As a result, the plate separator 7 is sandwiched between the edge ribs 3 of the panel form frames 1 to be connected, and the connector 6 guide pin 21 is inserted into the edge ribs 3 and the hole 44 for inserting the guide pin 21 of the plate separator 7. And pressed together with the plate separator 7. When the guide pin 21 insertion hole 32 provided in the horizontal butterfly material fastener 15 is fitted to the connecting pin 6 guide pin 21, the horizontal butterfly material clamp 8 is also held together. be able to.
Therefore, by fixing the panel foam frame 1 edge ribs 3 to each other, the plate separator 7 and the horizontal butterfly material fastener 8, the horizontal butterfly material fastener 8 and the horizontal butterfly material 14 are in the middle of the panelform mold frame 1. Since it is only necessary to support the concrete load acting on the rib 49, the load applied to the horizontal butterfly material fastener 8 and the horizontal butterfly material 14 is reduced. Useful for weight reduction by changing cross-sectional properties or cross-sectional shape.

The horizontal butterfly material temporary placement tool 9 shown in FIG. 6 is the tip of the guide pin 21 that appears when the connecting tool 6 guide pin 21 is inserted into the hole 44 through which the guide pin 21 between the panel form frame 1 edge ribs 3 is inserted. The guide pin 21 insertion hole 36 provided in the horizontal butterfly material temporary placement tool 9 is fitted into the part, and the receiving pin 29 is inserted into the insertion hole 23 for insertion of the receiving pin 29 that appears by fitting into the hole 36. The screw bolt 26 inserted and screwed through the movable member 25 is rotated and clamped to the female screw 22 provided at the axial center of the rear end portion of the guide pin 21.
As a result, in the work of attaching or removing the long and heavy horizontal butterfly material 14, work safety and work efficiency are improved by temporarily placing the work in a place where it cannot be reached.

FIG. 16 is an explanatory view showing a hanging tool 59 used for disassembling a form made up of a conventional round separator 53 and a panel form mold 1 and a state of disassembling the form, and the hanging of the present application shown in FIG. The stopper 59 includes a latch bolt 60 having one base portion and the other screw portion, a nut 62 screwed into the screw portion, and one end portion of a metal plate having a cross section of about 4 mm × 32 mm and a desired length. And a bolt receiving plate 61 in which a hole for inserting the retaining bolt 60 is drilled, and a hole for inserting the tip of the insulator bar 64 at the other end is provided. The base of the retaining bolt 60 is inserted and fixed in the hole for 60 insertion.
As a result, the fasteners 59 are fixed at the positions required for disassembling the molds in the holes 44 for inserting the guide pins 21 provided between the edge ribs 3 of the panel form frames 1 to be connected to each other, and the concrete is placed and solidified. In the subsequent operation of disassembling the control panel form 1, the lever bar 64 provided on the latch 59 bolt receiving plate 61 fixed between the edge ribs 3 of the connected control panel form 1 is inserted into the hole for inserting the tip. As shown in FIG. 16 (16 b), a support base 63 is provided on the panel form frame 1 on the side to which the latch 59 is not fixed, and the support base 63 is inserted into the lever bar 64. The panel form 1 is easily peeled (demolded) by pinching the end of the insulator bar 64 to the fulcrum.
Therefore, by making mold form dismantling easy, the damage to the panel form mold 1 is reduced, and the number of times the panel form form 1 is transferred is increased.

  As shown in FIG. 17, in a mold using a conventional round separator 53, a female portion provided on a screw portion 55 of a cone 54 and a base portion of a horizontal butterfly material 69 that are screwed to the round separator 53 with the sill plate 2 interposed therebetween. Screws are fixed to the screws, the horizontal butter material 14 is arranged above and below the horizontal butter material fasteners 69, and the nuts 19 that press the seat 10 inserted into the horizontal butter material fasteners 69 are tightened by hand. As a result, tightening of the nut 19 may not only apply an excessive tensile force to the round separator 53, but also a part of the dam plate 2 is drawn toward the side of the horizontal butterfly 14 as shown in FIG. Although it was difficult to deform into a curved shape, by using the plate separator 7 of the present application, the edge ribs 3 that sandwich the plate separator 7 between the panel form frame 1 edge ribs 3 and the horizontal butterfly material fastener 8 fit The body 15 is pressed and clamped together, and the horizontal flap 14 is arranged above and below the horizontal flap fastener 8. Since the horizontal flap member 14 by pressing the tightening nut 19 through the seat member 10 which inserted in the lateral flap member fastening tool 8 to resist compression, has the characteristic that does not affect the sheathing board 2.

The present invention uses the connector 6 in the panel form 1 and presses and clamps the adjacent panel form 1 border ribs 3 with screw bolts 26 as shown in FIGS. Thus, it is possible to provide the protruding portions 4 that protrude on both outer sides of the edge ribs 3 to be connected. For this reason, the inner corner surface of the end portion of the connecting side 47 having a substantially L shape including the fixed side 46 and the connecting side 47 is provided. There is a feature that the panel form frame 1 is lightened by providing a protruding portion 4 having a substantially waste-fold shape on the side and fixing the edge rib 3 having a large and small section modulus to the dam plate 2.
In addition, the fixing bolt 5 for fixing the board 2 and the edge rib 3 of the panel form 1 is fixed to the board 2 in advance with the fixing bolt 5 having a portion in contact with the board 2 formed in a substantially truncated pyramid wedge shape. When the fixing bolt 5 is inserted into the hole 42 for inserting the fixing bolt 5 and struck with a hammer or the like, the fixing bolt 5 is fixed by biting the dam plate 2.
Therefore, there is no rotation (idle rotation) in which the fixing bolt 5 and the nut 41 rotate together, and the fixing or removing operation of the dam plate 2 and the edge rib 3 is facilitated.

As shown in FIGS. 1 and 2, in the connector 6 of the present invention, plate separators 7 are sandwiched between adjacent ribs 3 of panel form frames 1 to be connected to each other, and provided on the edge ribs 3 and the plate separators 7. The guide pin 21 is inserted into the inserted hole 44 for inserting the guide pin 21, and the hole 32 provided in the horizontal butterfly material fastener 8 fitting body 15 is formed at the tip of the guide pin 21 that appears when the guide pin 21 is inserted. The receiving pin 29 is inserted into the insertion hole 23 for inserting the receiving pin 29 that is inserted into the distal end portion of the guide pin 21 and appears by fitting, and the female provided at the axial center of the rear end portion of the guide pin 21. By rotating a screw bolt 26 to be screwed onto the screw 22 via the movable member 25, the panel form frame 1 edge ribs 3 sandwiching the plate separator 7 and the horizontal butterfly material fastener 8 fitting body 15 together. There is a feature of pressing and clamping.
In addition, the receiving pin 29 inserted at the tip of the connector 6 guide pin 21 abuts against the edge rib 3 in the operation of connecting the panel form frame 1 edge ribs 3 to each other, whereby the screw bolt 26 and the connector 6 guide. By preventing co-rotation (idle rotation) of the pins 21 rotating together, the screw bolt 26 screwed to the rear end portion of the guide pin 21 via the movable member 25 is rotated with one hand by a screwdriver such as a screwdriver. There exists the characteristic which pressed and clamped the said panel form frame 1 edge ribs 3 mutually.

When comparing the conventional clip metal fitting 75 with the connector 6 of the present application, as shown in FIG. 20 and FIG. 21, the conventional connector called the clip metal fitting 75 has a required round length of about 13 mm and a high rigidity. Since the arm 80 extending at a right angle from the insertion shaft 79 and the sandwiching portion 81 continuous to the arm 80 are integrally processed into a substantially curved shape by steel, the connecting hole for connecting adjacent edge ribs 76 to each other The connecting shaft 79 is inserted by inserting the insertion shaft portion 79 with the arm 80 of the clip metal fitting 75 in a horizontal state, and striking the substantially curved holding portion 81 with a hammer or the like, and rotating the insertion shaft portion 79 around the rotation shaft. Since the ribs 76 are clamped by elastic pressure, the edge ribs 76 that are connected by excessive pressure may be deformed. In addition, the use of the clip fitting 75 causes noise when the roughly curved holding portion 81 is strongly struck with a hammer or the like.
In that respect, the connector 6 according to the present application rotates a screw bolt 26 screwed to the rear end portion of the guide pin 21 via the movable member 25 to the rear end portion of the guide pin 21 as shown in FIGS. When the movable member 25 advances and is pressed and pinched, the protruding portion 4 protruding outside the ends of the edge ribs 3 to be connected can be pressed and pinched without getting in the way, and almost no noise is generated. There is a feature that does not.
Further, in the connector 6 according to the present application, the receiving pin 29 inserted into the distal end portion of the guide pin 21 abuts on the edge rib 3 to prevent the guide pin 21 and the screw bolt 26 from rotating together (idling). By doing so, there is a feature that can be tightened with one hand using a screwdriver such as a screwdriver.
Furthermore, the connector 6 according to the present application can be used for connecting a resin mold (refer to FIG. 22) in which the support plate 84 and the edge rib 85 are integrated, or a steel mold called metal form (not shown). There are features.

Then, the receiving pin 29 is inserted into the insertion hole 23 for inserting the receiving pin 29 that appears when the guide pin 21 is fitted into the distal end portion, and the rear end portion of the guide pin 21 is interposed via the movable member 25. The screw bolt 26 to be screwed is rotated and clamped. This operation is sequentially repeated up to the position for repeated use, and the opposite partner panel form 1 is connected to the opposite form of the panel form by substantially the same procedure. The horizontal butterfly material 14 that supports the back portion of 1 is disposed above and below the horizontal butterfly material fastener 8, and the nut 11 that is screwed into the horizontal butterfly material fastener 8 is rotated to press and fix the horizontal butterfly material 14. This completes the solid formwork assembly for concrete placement (see FIGS. 11 and 12).
Note that the horizontal butterfly material temporary placement tool 9 shown in FIG. 3 is temporarily placed at a position where the hand can reach in a place where the hand cannot reach, thereby improving work safety and work efficiency.

The panel foam mold 1 is lightened by fixing the edge ribs 3 with a large section modulus and lightening to the dam plate 2. Specifically, by providing the substantially waste-shaped protruding portion 4 on the inner side of the connection side 47 of the substantially L-shaped edge rib 3 composed of the fixed side 46 and the connection side 47, the section modulus increases. The specified strength is maintained and the weight of the edge rib 3 is reduced. However, in order to be able to provide the projecting portions 4 projecting on both outer sides of the edge ribs 3, the connecting tool 6 that is pressed and clamped by the screw bolt 26 of the present application is used.
Further, the fixing bolt 5 shown in FIG. 8 for fixing the board 2 and the edge rib 3 of the panel form 1 is inserted into a hole 42 provided in the board 2 in advance, and the fixing bolt 5 is inserted into the fixing bolt 5. By hitting with a hammer or the like and biting into and fixing on the dam plate 2, the fixing bolt 5 and the nut 41 are not rotated (idle).
Therefore, the rotation of the fixing bolt 5 and the nut 41 is eliminated, so that the nut 41 is left in a state in which the panel 2 of the panel 1 is left after the concrete is solidified as shown in FIG. The panel form 1 is peeled off by removing the edge rib 3 and inserting the tip of the lever bar 58 into the hole 44 for inserting the guide pin 21 provided on the edge rib 3 on the counterpart side. .
Further, since the fixing bolt 5 and the nut 41 are not rotated (idly rotated), the work of replacing the damaged dam plate 2 becomes efficient.

As shown in FIG. 7, the connector 6 has a taper that has a taper that decreases in diameter as it approaches the tip of a cylindrical member having a required outer diameter of about 13 mm and an inner diameter of about 6 mm. A guide pin 21 provided with an insertion hole 23 for insertion of a receiving pin 29 and a female screw 22 formed on the axial center of the rear end portion having a predetermined length from the insertion hole 23;

A movable member 25 formed by drilling a hole through which the screw bolt 26 is inserted in the shaft center;
It is constituted by a screw bolt 26 that is screwed to a female screw 22 provided at the axial center of the guide pin 21 via a movable member 25 that is fitted to the rear end portion of the guide pin 21.
As a result, a hooking portion such as a screwdriver is hooked on the hooking hole 27 of a screw bolt 26 screwed to the female screw 22 provided on the shaft center of the rear end portion of the connector 6 guide pin 21 via the movable member 25. There is a feature that the movable member 25 is moved by rotating the screw bolt 26 to widen or narrow the clamping range 25s (clamping margin).
Further, in the rotation operation of the connecting tool 6 screw bolt 26, the receiving pin 29 inserted into the tip end portion of the guide pin 21 comes into contact with the edge rib 3, so that the guide pin 21 does not rotate. There is a feature that the screw bolt 26 can be tightened with one hand by a tool.
Further, since the receiving bolt 29 inserted into the guide pin 21 and the screw bolt 26 screwed through the movable member 25 movable back and forth are rotated to be pressed and clamped, the tightening force of the screw bolt 26 can be manually adjusted. There is a feature that can be adjusted.

The plate separator 7 is a support tool that supports the spacing between the ribs 3 of the panel forming mold 1 that are connected to face each other, and acts on the panel forming mold 1 that is connected by using the plate separating 7. The concrete load to be concentrated is concentrated on the plate separator 7, and the load is concentrated on the connector 6 guide pin 21 as a shearing force. Therefore, since the horizontal butterfly material fastener 8 and the horizontal butterfly material 14 need only support the concrete load acting on the intermediate rib 49, the concrete load acting on the horizontal butterfly material fastener 8 and the horizontal butterfly material 14 is Will be reduced.
Therefore, it helps to reduce the weight of the horizontal butterfly material fastener 8 and the horizontal butterfly material 14.
In addition, the work efficiency is improved because the sandwiching operation between the panel form frame 1 edge ribs 3 to be connected and the plate separator 7 and the horizontal butterfly material fastener 8 are sandwiched at the same place.

A substantially V-cut cross-sectional defect portion 12 that can be bent and cut is formed at a position about 1 mm from the concrete surface side of the frame 1 siding plate 2 toward the wall center.
Therefore, it is preferable to use a synthetic resin that does not generate rust from the cut portion in the concrete-released base finish. However, in order to prevent the occurrence of water leakage after the concrete is hardened, it is desirable that the embossed unevenness be uniformly processed over the entire peripheral surface portion.
The use of the synthetic resin plate separator 7 can provide the same strength as that of a conventional cold-worked metal round separator, and the post-treatment of the portion cut from the concrete surface can be omitted. is there.

A state in which the surface is used as a fulcrum of reaction force and the surface is scooped with a lever bar 66 is shown.
This makes it difficult to disassemble the mold by tangling the plurality of separator holes 57 provided in the panel form mold 1 sill plate 2 and the threaded portions 55 of the cone 54 screwed into the round separator 53 so as to stick to each other.
Further, an insulator bar 66 is inserted between the concrete 52 surface and the panel form 1 and the separator hole 57 provided in the siding plate 2 and the threaded portion 55 of the cone 54 are adhered to each other by forcibly squeezing the separator hole 57. The side portion 65 is cut to allow play in the separation hole 57. For this reason, when the separator plate 57 is used about 4 to 5 times, the separation hole 57 is gradually enlarged, so that replacement of the dam plate 2 is required.

As shown in FIG. 1 and FIG. 2, the panel separator 7 is sandwiched between the ribs 3 of the panel form 1 to be connected by the panel form 1 and the connector 6 of the present invention, and the edge that sandwiches the plate separator 7. By sandwiching the ribs 3 and the horizontal butterfly material fasteners 15 together, the assembling work becomes rational.
In addition, the edge rib 3 is lightened by providing a substantially waste-shaped protruding portion 4 that protrudes toward the inner corner surface side of the connecting side 47 end of the edge rib 3 that is fixed to the panel form 1, thereby increasing the section modulus. There is a feature that the weight of the panel form 1 is slightly reduced.
A receiving pin 29 is inserted into the distal end portion of the guide pin 21 to be inserted into the hole 44 between the panel form frame 1 edge ribs 3 to be coupled in the coupling tool 6, and movable to the rear end portion of the guide pin 21. There is a characteristic that the movable member 25 is moved by rotating the screw bolt 26 screwed through the member 25, and the clamping range 25s (the clamping margin) can be adjusted to be wide and narrow.
Further, in the tightening operation of the bolt 26 that presses the movable member 25 of the connector 6, the receiving pin 29 inserted into the distal end portion of the guide pin 21 comes into contact with the edge rib 3 to By preventing the screw bolts 26 from rotating together (idling), the screw bolts 26 can be tightened with one hand using a screwdriver such as a screwdriver.
Further, in the work of disassembling the formwork, the latch 59 is inserted into the hole 44 for inserting the guide pin 21 provided on the edge rib 3 from the side between the adjacent panel form mold 1 edge ribs 3. The end of the lever bar 64 is inserted into the hole for inserting the lever bar 64 provided in the latch 59 and fixed by the nut 62, and the side where the latch 59 is not fixed. The panel form 1 is easily peeled (demolded) by disposing the support base 63 on the panel form 1 and turning the end of the insulator bar 58 with the support base 63 as a fulcrum. To do. (See Figure 16)

Further, the use of the conventional round separator 53 means that a plurality (about 5 to 6 places) of round separators 53 fixed to the opposing one side mold base plate 2 and the other side mold base plate 2 ( There is a problem that it takes time to work with a plurality of (about 5 to 6) separator holes 57 provided in the return mold). On the other hand, the above-mentioned difficulty is solved by using the panel form 7 and the plate separator 7 by sandwiching the plate 7 between the adjacent panel form 1 and the edge rib 3 of the present application. There is a feature to let you.
Further, as shown in (4b) of FIG. 4, the panel form 1 edge rib 3 and the conventional resin mold frame 92 can be connected, and the resin mold frames 92 shown in FIG. It has the feature that it can be used to connect steel molds that are foam (registered trademark).

  The present invention relates to a concrete mold.

The structure of the formwork using the conventional pier fixed formwork for concrete molding will be described with reference to FIGS.
The pier fixed formwork is a lavan plywood (sometimes referred to as a control panel) or a synthetic resin plate 2 or the like. It is fixed. As for the connection of the pier fixed formwork, the piers 67 fixed to the edges of the adjacent pier fixed form frames are butt-joined, and a nail 74 is driven into and fixed to the pierced crosspieces 67 and connected to a desired position. By inserting the screw portions 55 of the cones 54 to be screwed into the both ends of the round separator 53 into the separator holes 57 provided in the connected fixed board frame 2, the screw portions 55 of the cone 54 excluding the barrier plate 2 are inserted. The horizontal butterfly material fastener 69 or foam tie (registered trademark) is screwed and fixed to the upper and lower sides of the horizontal butterfly material fastener 69, and the horizontal butterfly material 14 that supports the back portion of the fixed frame frame is disposed. In general, a method of tightening and fixing the horizontal butterfly material 14 by rotating a nut 19 screwed through a seating tool 10 to be inserted into the threaded portion of the horizontal butterfly material fastener 69 is generally used.
However, in this construction method, after the fixed frame 67 fixed mold frame on the opposite side is arranged, the screw portion 55 of the cone 54 screwed to the round separator 53 fixed to the fixed frame 67 fixed mold frame and the opposite fixed frame mold Aligning with the separation hole 57 provided in the frame, and sandwiching the berth fixed mold frame board 2 on the opposite side to the screw portion 55 of the cone 54, the horizontal butterfly material fastener 69 or the screw portion 55 of the cone 54 Form tie (registered trademark) is screwed and fixed, but there are a plurality (about 5 to 6) of screw portions 55 of the cone 54 that are fixed to a piercing fixed form frame arranged on one side, and so on. It is difficult to match with a plurality of (about 5 to 6) separator holes 57 provided on the side fixing frame.
Also, in the part dismantling of the formwork, the place where the lever bar cannot be hooked has a problem that the formwork may be damaged by forcibly removing the crosspiece and forcibly inserting the tip of the lever bar into the joint between the slats 2 .
Further, when the conventional round separator 53 is used, if the tightening force of the nut 19 screwed into the thread portion of the lateral butterfly material fastener 69 becomes excessive, the swash plate 2 becomes the lateral butterfly material 14 as shown in FIG. There is a drawback that it is pulled to the side and deformed into a curved shape.

FIG. 19 is a perspective view showing an example of a state in which the connecting portion of the conventional pier fixed formwork is connected with a nail, and the opposite hands are obtained by holding the piers 67 fixed to the edge of the fixed pedestal frame with one hand. A method of driving the nail 74 with a hammer is common. However, in this method, due to vibration when the nail 74 is driven with a hammer, the mutually connected piers 67 are slightly moved in different directions, and the slats 2 are likely to be mistaken or stepped. For this reason, a connecting tool called a vise-like crosspiece clamp (PAT) is on the market (refer to page 71 of Non-Patent Document 1 for a crosspiece clamp).
In addition, with regard to the connection of the fixed frame frames to be connected, in the work of driving and fixing the nails 74 at the same time as performing the level and face-to-face adjustment between the fixed frame frames 67 of the fixed frame type, an experienced technician is required, There is a difficulty in securing employment of workers.
Furthermore, since the pier 67 serving as the skeleton of the pier fixed formwork is made of wood, it has a disadvantage that it is bent by drying and the strength becomes unstable due to deformation such as torsion or nodes.

  Hereinafter, an example of a conventional concrete forming mold and its connecting tool will be described with reference to FIGS. 18 and 20 to 22.

In the H joint 70 shown in FIG. 18, a partition portion 71 and a fixing portion 72 are integrally formed of a steel plate of about 1 mm, and a nail hole 73 is provided in the fixing portion 72.
This H-joint 70 is used for the purpose of connecting and mating the panels 2 of the panel or the synthetic resin plate having a thickness of about 12 mm. However, since the accuracy of the seam portion where the plates 2 are connected to each other is inferior, There are disadvantages that are not suitable.

20 and 21 are reference views showing a connection state in which a clip metal fitting 75 is used in a conventional edge rib 76 fixed mold, and the rib fixed mold is a cue such as a panel (Lawan plywood) or a synthetic resin board. A substantially L-shaped edge rib 76 is fixed to the edge of the back surface of the plate 2 with a countersunk bolt 77, and a vertical butterfly material is disposed and fixed to the middle part.
The edge rib 76 fixed formwork is mainly used for formwork of residential buildings, but in Japanese residential buildings, since the wall and the slab (floor) on the upper floor are integrally constructed, after concrete casting However, although the formwork dismantling material is moved to the upper floor, the slab (floor) on the upper floor becomes an obstacle, and there is a difficulty that heavy machinery cannot be used for unloading work. Therefore, it is required to make it lighter by hand.
The clip metal fitting 75 includes an insertion shaft portion 79 that is inserted into a hole between the edge ribs 76 to be connected by processing a bar having high rigidity such as iron, and an arm 80 that extends perpendicularly from the insertion shaft portion 79. The arm 80 is formed of a generally curved holding portion 81 formed integrally with the arm 80.
As a result, the insertion shaft portion 79 is inserted in a state where the arm 80 of the clip metal fitting 75 is horizontally inserted into the connection hole between the edge ribs 76 to be connected, and the holding portion 81 supported by the arm 80 extending at a right angle from the insertion shaft portion 79 is provided. The hammer is struck with a hammer and the edge ribs 76 are sandwiched with excessive strength. Therefore, as shown in FIG. 21, there is a difficulty that the gap between the edge rib 76 and the edge rib 76 cannot be maintained and is deformed.
In addition, if the sandwiching width 82, which is the thickness dimension of the sandwiched object, is too wide, a gap is formed between the connecting board 2 and the connecting board 2, and the liquid portion of the concrete (cement nose) protrudes from the gap and protrudes from the concrete surface. There is a difficulty that can form burr.
Further, a retaining hole 78 for a screwdriver or the like is provided on the head of the countersunk bolt 77 used for fixing the weir plate 2 and the edge rib 76, and once used, the retaining hole 78 is filled with concrete, and the weir plate 2 There is a drawback that it becomes difficult to remove the flat bolt 77 by rotating the flat bolt 77 and the nut together at the time of replacement. Therefore, there is a difficulty that the countersunk bolt 77 that has been removed cannot be reused.

FIG. 22 is a perspective view showing a connection state of the resin mold 92 and its mold connector, and the mold connector 83a shown in FIG. 22 (22a) is inserted into the connection hole 86 between the edge ribs 85. The arm 91 extends from the insertion shaft portion 87 at a right angle, and the holding portion 90 is formed integrally with the arm 91.
About this, in order to pinch the front-end | tip part of edge ribs 85, a clearance gap may be made in the part 84 part of resin-molding molds to connect, Therefore, as shown in FIG. There has been proposed the formwork coupler 83b in which a male screw is formed at the distal end of the insertion shaft portion 88 to be inserted into the coupling hole 86, and is tightened and pressed with a nut 89 to close the gap between the baffle plates 84 (for example, (See FIG. 4 of Patent Document 5.)
In addition, since the slat plate 84 and the edge rib 85 are formed integrally with the resin molding die 92, there is a difficulty in that the severing slat plate 84 cannot be replaced.
Further, the mold connecting tool 83b takes time and labor for screwing the nut 89, and when disassembling the mold after solidifying the concrete, the male screw at the tip of the insertion shaft portion 88 and the connecting hole 86 between the edge ribs 85 are provided. However, since it is difficult to slip due to friction, it takes time for the extraction work, and there is a difficulty that the screw portion is damaged due to friction between the connecting hole 86 of the edge ribs 85 and the screw portion at the tip of the insertion shaft portion 88.

  The butter material that supports the back of the formwork includes a square pipe such as a steel pipe, a vinyl chloride pipe, and an aluminum pipe, and generally a single pipe of 48.6φ is mainly used. However, recently, square pipes such as light PVC pipes and aluminum pipes have attracted attention.

Issued by Marui Construction Parts Catalog No.9 / Marui Sangyo Co., Ltd. Product catalog No.3, formwork, Okabe Co., Ltd.

  The present invention has been made in view of the above-described points. Conventionally, an edge rib is fixed to the back surface of a lauan plywood having a thickness of about 12 mm (hereinafter also referred to simply as a panel) or a synthetic resin board. As shown in FIG. 2 to FIG. 4, the panel form mold 1 of the present application, which is slightly different from the edge rib fixed mold form, has protrusions on both outsides of the adjacent panel form mold 1 edge ribs 3. 20 and FIG. 21, which is a formwork connecting tool of FIG. 20, or the formwork connecting tool shown in FIG. 22 cannot be used.

  In a conventional formwork such as a pedestal fixed formwork or an edge rib fixed formwork, there is a problem that there is not enough space between connecting parts that connect adjacent formwork, so that the insulator bar cannot be inserted.

Since concrete structures (frames) in Japanese residential buildings are constructed with the wall and the slab (floor) directly above the floor, when the formwork material after dismantling the formwork is moved to the floor directly above, Since the slab (floor) becomes an obstacle and it is difficult to use heavy machinery, the panel form 1 is moved by hand, and it is required to reduce the weight of the panel form 1 as much as possible.
In addition, in the conventional edge rib fixed formwork, since the conventional countersunk head bolt is used to fix the sill plate 2 and the edge rib, concrete is filled into the retaining holes 78 of the countersunk head bolt driver, etc. once used. By doing so, it becomes impossible to hook a screwdriver or the like that stops the countersunk head bolt from rotating. For this reason, there has been a difficulty that the countersunk head bolt is difficult to be removed or tightened by turning the countersunk head bolt and the nut together (idle rotation).

The present invention has been made in view of the above-described points, and a mode for solving the above-described problems will be described with reference to FIGS. In addition, the one-side drawing of the symmetrical part which does not interfere with description is abbreviate | omitted.
The board 2 constituting the panel form 1 is a lauan plywood (hereinafter sometimes referred to simply as a panel) having a thickness of about 12 mm or a synthetic resin board, and the edge rib 3 fixed to the board 2 is used. Presupposes the use of metal or synthetic resin.
Furthermore, it is assumed that the material used for the connector 6 that connects the adjacent panel form frame 1 edge ribs 3 to each other is made of metal or synthetic resin.

The panel form frame 1 is used for inserting the fixing bolt 5 into the fixed side 46 of the forming material provided with the protruding portion 4 on the inner corner surface side of the end portion of the connection side 47 having a substantially L shape composed of the fixed side 46 and the connection side 47. The holes 43 are provided at regular intervals, and the edge ribs 3 in which the holes 44 for inserting the connector 6 guide pins 21 are provided at regular intervals on the coupling side are fixed to the coupling portion of the dam plate 2. Accordingly, the protrusion 4 is provided on the inner corner surface side of the end portion of the connection side 47 that is substantially L-shaped, so that the section modulus is increased and the lightened edge rib 3 is fixed, so that the panel form 1 is lightened. However, since there are the protrusions 4 protruding on both outer sides of the edge ribs 3 to be connected, the conventional connector cannot be used, and the connector 6 of the present application is used.
Further, as shown in FIG. 2, a gap is provided between the edge ribs 3 in order to insert the plate separator 7 between the panel form frame 1 edge ribs 3 and to facilitate disassembly of the formwork.

As shown in FIG. 8, the fixing bolt 5 for fixing the panel form frame 1 sill plate 2 and the edge rib 3 has a head portion 38 having a substantially conical dish shape, a body portion 39 having a substantially truncated pyramid wedge shape, and a screw portion 40 having a truncated cone shape. A male screw that is screwed into the nut 41 is integrally formed. As a result, the fixing bolt 5 is inserted into the hole 42 provided in advance in the dam plate 2 and the head 38 of the fixing bolt 5 is struck with a hammer or the like so that the head 38 and the body 39 are formed. In order to bite and fix on the weir plate 2, the co- rotation (idle rotation) in which the fixing bolt 5 and the nut 41 rotate together is eliminated.
Therefore, as shown in FIG. 15, after the concrete is solidified, the connecting tool 6 is removed, and the nut 41 for fixing one edge rib 3 is rotated with the panel form frame 1 retaining plate 2 left, and the edge rib 3 is removed. The tip of the insulator bar 58 is inserted into the hole 44 for inserting the connector 6 guide pin 21 provided on the other edge rib 3, and the remaining panel form frame 1 slat plate 2 is used as a fulcrum for the reaction force. According to the principle of the insulator, the panel form frame 1 and the board 2 are easily peeled off (demolded).

As shown in FIG. 7, the connecting tool 6 is inserted into a guide pin 21 to be inserted into the hole 44 between the edge ribs 3 to be connected, and an insertion hole 23 for inserting a receiving pin 29 provided at the tip of the guide pin 21. A receiving pin 29 to be inserted and a screw bolt 26 screwed to the rear end portion via the movable member 25 are configured.
As a result, the connecting tool 6 guide pin 21 is inserted into the hole 44 between the adjacent panel form frame 1 edge ribs 3, and the receiving pin 29 is inserted into the insertion hole 23 for inserting the receiving pin 29 that appears. The movable member 25 advances by inserting and rotating the screw bolt 26 screwed to the rear end portion of the guide pin 21 via the movable member 25, and presses and holds the edge ribs 3 together. That is, there is a feature that the screw bolt 26 screwed to the rear end portion of the guide pin 21 via the movable member 25 is pressed and clamped by rotating.
Further, there is a feature that the movable member 25 is moved by rotating the screw bolt 26 so that the clamping range 25s (clamping margin) can be narrowed widely.
Further, when the receiving pin 29 inserted into the insertion hole 23 for inserting the receiving pin 29 at the tip end portion of the guide pin 21 abuts against the edge rib 3, the guide pin 21 and the screw bolt 26 rotate together. ), The screw bolt 26 can be tightened with one hand using a screwdriver such as a screwdriver.

As shown in FIG. 5, the horizontal butterfly material fastener 8 is fitted with a fitting member formed by bending a metal plate of a desired size into a substantially unequal side L-shape consisting of a fitting side 30 and a connecting side 31. A fitting body 15 having a hole 44 through which the guide pin 21 is inserted in the side 30 and a hole 16 for inserting a connecting bolt 18 for connecting a shaft bolt 17 called a foam tie (registered trademark) to the connecting side 31 is formed. The bolt insertion hole 16 and the female screw provided in the base portion 56 of the shaft bolt 17 are matched with each other and connected by the connecting bolt 18.
As a result, the connecting tool 6 guide pin 21 is inserted into the hole 44 for inserting the connecting tool 6 guide pin 21 provided between the adjacent panel form frame 1 edge ribs 3, and the connecting tool 6 guide that appears as a result of the insertion. The pin 21 can be used by being fitted to the tip.

The plate separator 7 is formed of a metal material or a synthetic resin material with holes for inserting guide pins 21 at both ends of a strip-shaped separate member having a desired length, and is positioned inwardly (wall-centered) from the hole. Specifically, the groove of the cross-sectional defect portion 12 that makes it easy to bend and cut at a position slightly inward (wall center) from the concrete surface side of the panel form frame 1 siding plate 2 is approximately V-cut. To form.
As a result, the plate separator 7 is sandwiched between the edge ribs 3 of the panel form frames 1 to be connected, and the connector 6 guide pin 21 is inserted into the edge ribs 3 and the hole 44 for inserting the guide pin 21 of the plate separator 7. And pressed together with the plate separator 7. When the guide pin 21 insertion hole 32 provided in the horizontal butterfly material fastener 15 is fitted to the connecting pin 6 guide pin 21, the horizontal butterfly material clamp 8 is also held together. be able to.
Therefore, by fixing the panel foam frame 1 edge ribs 3 to each other, the plate separator 7 and the horizontal butterfly material fastener 8, the horizontal butterfly material fastener 8 and the horizontal butterfly material 14 are in the middle of the panelform mold frame 1. Since it is only necessary to support the concrete load acting on the rib 49, the load applied to the horizontal butterfly material fastener 8 and the horizontal butterfly material 14 is reduced. Useful for weight reduction by changing cross-sectional properties or cross-sectional shape.

The horizontal butterfly material temporary placement tool 9 shown in FIG. 6 is the tip of the guide pin 21 that appears when the connecting tool 6 guide pin 21 is inserted into the hole 44 through which the guide pin 21 between the panel form frame 1 edge ribs 3 is inserted. The guide pin 21 insertion hole 36 provided in the horizontal butterfly material temporary placement tool 9 is fitted into the part, and the receiving pin 29 is inserted into the insertion hole 23 for insertion of the receiving pin 29 that appears by fitting into the hole 36. The screw bolt 26 inserted and screwed through the movable member 25 is rotated and clamped to the female screw 22 provided at the axial center of the rear end portion of the guide pin 21.
As a result, in the work of attaching or removing the long and heavy horizontal butterfly material 14, work safety and work efficiency are improved by temporarily placing the work in a place where it cannot be reached.

FIG. 16 is an explanatory view showing a hanging tool 59 used for disassembling a form made up of a conventional round separator 53 and a panel form mold 1 and a state of disassembling the form, and the hanging of the present application shown in FIG. The stopper 59 includes a latch bolt 60 having one base portion and the other screw portion, a nut 62 screwed into the screw portion, and one end portion of a metal plate having a cross section of about 4 mm × 32 mm and a desired length. And a bolt receiving plate 61 in which a hole for inserting the retaining bolt 60 is drilled, and a hole for inserting the tip of the insulator bar 64 at the other end is provided. The base of the retaining bolt 60 is inserted and fixed in the hole for 60 insertion.
As a result, the fasteners 59 are fixed at the positions required for disassembling the molds in the holes 44 for inserting the guide pins 21 provided between the edge ribs 3 of the panel form frames 1 to be connected to each other, and the concrete is placed and solidified. In the subsequent operation of disassembling the control panel form 1, the lever bar 64 provided on the latch 59 bolt receiving plate 61 fixed between the edge ribs 3 of the connected control panel form 1 is inserted into the hole for inserting the tip. As shown in FIG. 16 (16 b), a support base 63 is provided on the panel form frame 1 on the side to which the latch 59 is not fixed, and the support base 63 is inserted into the lever bar 64. The panel form 1 is easily peeled (demolded) by pinching the end of the insulator bar 64 to the fulcrum.
Therefore, by making mold form dismantling easy, the damage to the panel form mold 1 is reduced, and the number of times the panel form form 1 is transferred is increased.

  As shown in FIG. 17, in a mold using a conventional round separator 53, a female portion provided on a screw portion 55 of a cone 54 and a base portion of a horizontal butterfly material 69 that are screwed to the round separator 53 with the sill plate 2 interposed therebetween. Screws are fixed to the screws, the horizontal butter material 14 is arranged above and below the horizontal butter material fasteners 69, and the nuts 19 that press the seat 10 inserted into the horizontal butter material fasteners 69 are tightened by hand. As a result, tightening of the nut 19 may not only apply an excessive tensile force to the round separator 53, but also a part of the dam plate 2 is drawn toward the side of the horizontal butterfly 14 as shown in FIG. Although it was difficult to deform into a curved shape, by using the plate separator 7 of the present application, the edge ribs 3 that sandwich the plate separator 7 between the panel form frame 1 edge ribs 3 and the horizontal butterfly material fastener 8 fit The body 15 is pressed and clamped together, and the horizontal flap 14 is arranged above and below the horizontal flap fastener 8. Since the horizontal flap member 14 by pressing the tightening nut 19 through the seat member 10 which inserted in the lateral flap member fastening tool 8 to resist compression, has the characteristic that does not affect the sheathing board 2.

The present invention uses the connector 6 in the panel form 1 and presses and clamps the adjacent panel form 1 border ribs 3 with screw bolts 26 as shown in FIGS. Thus, it is possible to provide the protruding portions 4 that protrude on both outer sides of the edge ribs 3 to be connected. For this reason, the inner corner surface of the end portion of the connecting side 47 having a substantially L shape including the fixed side 46 and the connecting side 47 is provided. There is a feature that the panel form frame 1 is lightened by providing a protruding portion 4 having a substantially waste-fold shape on the side and fixing the edge rib 3 having a large and small section modulus to the dam plate 2.
In addition, the fixing bolt 5 for fixing the board 2 and the edge rib 3 of the panel form 1 is fixed to the board 2 in advance with the fixing bolt 5 having a portion in contact with the board 2 formed in a substantially truncated pyramid wedge shape. When the fixing bolt 5 is inserted into the hole 42 for inserting the fixing bolt 5 and struck with a hammer or the like, the fixing bolt 5 is fixed by biting the dam plate 2.
Accordingly, there is no co- rotation (idle rotation) in which the fixing bolt 5 and the nut 41 rotate together, and the fixing or removing operation of the dam plate 2 and the edge rib 3 is facilitated.

As shown in FIGS. 1 and 2, in the connector 6 of the present invention, plate separators 7 are sandwiched between adjacent ribs 3 of panel form frames 1 to be connected to each other, and provided on the edge ribs 3 and the plate separators 7. The guide pin 21 is inserted into the inserted hole 44 for inserting the guide pin 21, and the hole 32 provided in the horizontal butterfly material fastener 8 fitting body 15 is formed at the tip of the guide pin 21 that appears when the guide pin 21 is inserted. The receiving pin 29 is inserted into the insertion hole 23 for inserting the receiving pin 29 that is inserted into the distal end portion of the guide pin 21 and appears by fitting, and the female provided at the axial center of the rear end portion of the guide pin 21. By rotating a screw bolt 26 to be screwed onto the screw 22 via the movable member 25, the panel form frame 1 edge ribs 3 sandwiching the plate separator 7 and the horizontal butterfly material fastener 8 fitting body 15 together. There is a feature of pressing and clamping.
In addition, the receiving pin 29 inserted at the tip of the connector 6 guide pin 21 abuts against the edge rib 3 in the operation of connecting the panel form frame 1 edge ribs 3 to each other, whereby the screw bolt 26 and the connector 6 guide. By preventing co-rotation (idle rotation) of the pins 21 rotating together, the screw bolt 26 screwed to the rear end portion of the guide pin 21 via the movable member 25 is rotated with one hand by a screwdriver such as a screwdriver. There exists the characteristic which pressed and clamped the said panel form frame 1 edge ribs 3 mutually.

When comparing the conventional clip metal fitting 75 with the connector 6 of the present application, as shown in FIG. 20 and FIG. 21, the conventional connector called the clip metal fitting 75 has a required round length of about 13 mm and a high rigidity. Since the arm 80 extending at a right angle from the insertion shaft 79 and the sandwiching portion 81 continuous to the arm 80 are integrally processed into a substantially curved shape by steel, the connecting hole for connecting adjacent edge ribs 76 to each other The connecting shaft 79 is inserted by inserting the insertion shaft portion 79 with the arm 80 of the clip metal fitting 75 in a horizontal state, and striking the substantially curved holding portion 81 with a hammer or the like, and rotating the insertion shaft portion 79 around the rotation shaft. Since the ribs 76 are clamped by elastic pressure, the edge ribs 76 that are connected by excessive pressure may be deformed. In addition, the use of the clip fitting 75 causes noise when the roughly curved holding portion 81 is strongly struck with a hammer or the like.
In that respect, the connector 6 according to the present application rotates a screw bolt 26 screwed to the rear end portion of the guide pin 21 via the movable member 25 to the rear end portion of the guide pin 21 as shown in FIGS. When the movable member 25 advances and is pressed and pinched, the protruding portion 4 protruding outside the ends of the edge ribs 3 to be connected can be pressed and pinched without getting in the way, and almost no noise is generated. There is a feature that does not.
Further, in the connector 6 according to the present application, the receiving pin 29 inserted into the distal end portion of the guide pin 21 abuts on the edge rib 3 to prevent the guide pin 21 and the screw bolt 26 from rotating together (idling). By doing so, there is a feature that can be tightened with one hand using a screwdriver such as a screwdriver.
Furthermore, the connector 6 according to the present application can be used for connecting a resin mold (refer to FIG. 22) in which the support plate 84 and the edge rib 85 are integrated, or a steel mold called metal form (not shown). There are features.

On the fixed side 46 of the substantially L-shaped material, holes 43 for inserting the fixing bolts 5 for fixing to the bottom plate 2 are provided at regular intervals, and the projection 4 having a generally waste folding shape is formed on the inner corner surface side of the end of the connecting side 47. A panel form frame formed by fixing the edge rib 3 having a predetermined length in which holes 44 for inserting the connector 6 guide pins 21 are provided at regular intervals to the substantially end face of the back plate 2 back surface connecting portion. 1 and
As shown in FIG. 7, an insertion hole 23 for inserting a receiving pin 29 is provided at the rear of the tapered portion having a taper that decreases in diameter as it approaches the tip of a cylindrical member having a desired length. A receiving pin 29 is inserted into an insertion hole 23 for inserting a receiving pin 29 behind the tapered portion into a guide pin 21 provided with a female screw 22 at the axial center of the rear end portion having a certain length, and the guide pin A connector 6 in which a screw bolt 26 is fitted to the rear end portion of 21 via a movable member 25;
A plate separator provided with holes through which the connector 6 guide pins 21 are inserted at both ends of a belt-like member having a rectangular cross section with a thickness of about 4 mm and a width of about 30 mm, which supports between opposing molds. 7 and
As shown in FIG. 5, a hole 44 through which the guide pin 21 is inserted into a fitting member formed in a substantially unequal side L-shape composed of a fitting side 30 and a connecting side 31 is drilled in a metal plate having a desired dimension, The fitting body 15 in which a connecting bolt 18 insertion hole for connecting to a shaft bolt 17 called a foam tie (registered trademark) is drilled in the connecting side 31 is connected to the hole 56 for inserting the connecting bolt 18 and the base 56 of the shaft bolt 17. A horizontal butterfly material fastening tool 8 which is matched with a female screw provided on the joint and connected by a connecting bolt 18 for connection,
As shown in FIG. 2, in the state where the plate separator 7 is sandwiched between the panel form frame 1 edge ribs 3 to be connected, the edge ribs 3 and the hole 44 for inserting the guide pin 21 provided in the plate separator 7. The connector 6 guide pin 21 is inserted. Then, the hole 32 provided in the horizontal butterfly material fastener 8 fitting body 15 is fitted to the distal end portion of the guide pin 21 at the distal end portion of the guide pin 21 that appears when the connecting pin 6 guide pin 21 is inserted. Include. Then, the receiving pin 29 is inserted into the insertion hole 23 for inserting the receiving pin 29 that appears when the guide pin 21 is fitted into the distal end portion, and the rear end portion of the guide pin 21 is interposed via the movable member 25. The screw bolt 26 to be screwed is rotated and clamped. This operation is sequentially repeated up to the position for repeated use, and the opposite partner panel form 1 is connected to the opposite form of the panel form by substantially the same procedure. The horizontal butterfly material 14 that supports the back portion of 1 is disposed above and below the horizontal butterfly material fastener 8, and the nut 11 that is screwed into the horizontal butterfly material fastener 8 is rotated to press and fix the horizontal butterfly material 14. This completes the solid formwork assembly for concrete placement (see FIGS. 11 and 12).
Note that the horizontal butterfly material temporary placement tool 9 shown in FIG. 3 is temporarily placed at a position where the hand can reach in a place where the hand cannot reach, thereby improving work safety and work efficiency.

The panel foam mold 1 is lightened by fixing the edge ribs 3 with a large section modulus and lightening to the dam plate 2. Specifically, by providing the substantially waste-shaped protruding portion 4 on the inner side of the connection side 47 of the substantially L-shaped edge rib 3 composed of the fixed side 46 and the connection side 47, the section modulus increases. The specified strength is maintained and the weight of the edge rib 3 is reduced. However, in order to be able to provide the projecting portions 4 projecting on both outer sides of the edge ribs 3, the connecting tool 6 that is pressed and clamped by the screw bolt 26 of the present application is used.
Further, the fixing bolt 5 shown in FIG. 8 for fixing the board 2 and the edge rib 3 of the panel form 1 is inserted into a hole 42 provided in the board 2 in advance, and the fixing bolt 5 is inserted into the fixing bolt 5. By hitting with a hammer or the like to bite and fix on the dam 2, the fixing bolt 5 and the nut 41 do not rotate together (idle).
Accordingly, since the joint bolt 5 and the nut 41 are not co- rotated (idle), the nut 41 is left in a state in which the panel 2 of the panel 1 is left after the concrete is solidified as shown in FIG. The panel form 1 is peeled off by removing the edge rib 3 and inserting the tip of the lever bar 58 into the hole 44 for inserting the guide pin 21 provided on the edge rib 3 on the counterpart side. .
In addition, since the joint bolt 5 and the nut 41 do not co- rotate (idle), it is possible to efficiently replace the damaged damage plate 2.

As shown in FIG. 7, the connector 6 has a taper that has a taper that decreases in diameter as it approaches the tip of a cylindrical member having a required outer diameter of about 13 mm and an inner diameter of about 6 mm. A guide pin 21 provided with an insertion hole 23 for insertion of a receiving pin 29 and a female screw 22 formed on the axial center of the rear end portion having a predetermined length from the insertion hole 23;
A substantially P-shaped receiving pin 29 inserted into the insertion hole 23 for inserting the receiving pin 29 provided at the rear of the tapered portion, and a substantially end-cap-shaped fitting fitted to the rear end portion of the guide pin 21. A movable member 25 formed by drilling a hole through which the screw bolt 26 is inserted in the shaft center;
It is constituted by a screw bolt 26 that is screwed to a female screw 22 provided at the axial center of the guide pin 21 via a movable member 25 that is fitted to the rear end portion of the guide pin 21.
As a result, a hooking portion such as a screwdriver is hooked on the hooking hole 27 of a screw bolt 26 screwed to the female screw 22 provided on the shaft center of the rear end portion of the connector 6 guide pin 21 via the movable member 25. There is a feature that the movable member 25 is moved by rotating the screw bolt 26 to widen or narrow the clamping range 25s (clamping margin).
Further, in the rotation operation of the connecting tool 6 screw bolt 26, the receiving pin 29 inserted into the tip end portion of the guide pin 21 comes into contact with the edge rib 3, so that the guide pin 21 does not rotate. There is a feature that the screw bolt 26 can be tightened with one hand by a tool.
Further, since the receiving bolt 29 inserted into the guide pin 21 and the screw bolt 26 screwed through the movable member 25 movable back and forth are rotated to be pressed and clamped, the tightening force of the screw bolt 26 can be manually adjusted. There is a feature that can be adjusted.

The plate separator 7 is a support tool that supports the spacing between the ribs 3 of the panel forming mold 1 that are connected to face each other, and acts on the panel forming mold 1 that is connected by using the plate separating 7. The concrete load to be concentrated is concentrated on the plate separator 7, and the load is concentrated on the connector 6 guide pin 21 as a shearing force. Therefore, since the horizontal butterfly material fastener 8 and the horizontal butterfly material 14 need only support the concrete load acting on the intermediate rib 49, the concrete load acting on the horizontal butterfly material fastener 8 and the horizontal butterfly material 14 is Will be reduced.
Therefore, it helps to reduce the weight of the horizontal butterfly material fastener 8 and the horizontal butterfly material 14.
In addition, the work efficiency is improved because the sandwiching operation between the panel form frame 1 edge ribs 3 to be connected and the plate separator 7 and the horizontal butterfly material fastener 8 are sandwiched at the same place.

Hereinafter, this embodiment will be described in more detail with reference to FIGS.
It is assumed that the horizontal butterfly material 14 that supports the back of the panel form 1 is a single tube 48.6φ and the intermediate rib 49 is a crosspiece 67. Further, as shown in FIG. 17, the conventional round separator 53 is a type in which a cone 54 having a substantially truncated cone shape is screwed and fixed to both ends of a round separator 53 on male screws provided with round threads on both ends of a round steel. It is assumed that is used.
In addition, the one-side drawing of the symmetrical part which does not interfere with description is abbreviate | omitted.

The guide pin 21 is inserted into the hole for inserting the guide pin 21 provided in the guide pin 21 and is inserted into the front end portion of the guide pin 21 that appears as a result of the insertion. The receiving pin 29 is inserted into the insertion hole 23 for inserting the receiving pin 29 that appears when the hole 32 is fitted into the distal end portion of the guide pin 21, and is fitted into the rear end portion of the guide pin 21. The state which pressed and clamped by rotating the screw volt | bolt 26 which presses the back part of the movable member 25 to perform is shown.

The plate separator 7 is formed of a metal material or a synthetic resin material with holes for inserting guide pins 21 at both ends of the belt-like shape having a desired length. A substantially V-cut cross-sectional defect portion 12 that can be bent and cut is formed at a position about 1 mm from the concrete surface side of the frame 1 siding plate 2 toward the wall center.
Therefore, it is preferable to use a synthetic resin that does not generate rust from the cut portion in the concrete-released base finish. However, in order to prevent the occurrence of water leakage after the concrete is hardened, it is desirable that the embossed unevenness be uniformly processed over the entire peripheral surface portion.
The use of the synthetic resin plate separator 7 can provide the same strength as that of a conventional cold-worked metal round separator, and the post-treatment of the portion cut from the concrete surface can be omitted. is there.
The cross-sectional dimension of the plate separator 7 is preferably about 2.3 mm thick x about 30 mm wide in the case of a metal material, and about 5 mm thick x about 30 mm wide in the case of a synthetic resin material.
