Description

  The present invention relates to a mold for concrete molding.

A formwork (also referred to as a panel formwork form) used for conventional concrete molding and its connector will be described.

As shown in FIG. 9 (N), the conventional formwork has a wooden edge rib (38c) (also referred to as a crosspiece) for reinforcing and connecting the end of the bottom plate (2) by screw nails (39b). It is fixed and processed to a certain size (for example, a width of about 600 mm × 2700 mm). Further, for the connection of the formwork, a method is generally adopted in which the edge ribs (38c) are brought into contact with each other and the round nail (40b) is driven and fixed.

The above method is convenient and convenient, but in the work of connecting the formwork, the front and back of the formwork plate (2) to be connected and the vertical alignment of the left and right are manually performed and connected with one hand. Grab the edge ribs and drive and fix the round nail (40b) with the other hand. This operation is troublesome and requires a skilled person. Further, since the front and rear surface alignment and the left and right vertical alignment of the molds to be connected are made by visual adjustment, there is a drawback that it is difficult to maintain a certain accuracy.

Therefore, in the connection of piers having a formwork configuration, the piers to be connected are grasped with one hand, and a generally vise-shaped connecting tool is fitted into the piers with the other hand and screwed into a screw bolt. A connecting tool called a crosspiece clamp that fastens and fixes a nut is used. (For example, refer nonpatent literature 1.) However, although the said connection tool has the advantage which does not need the nail | punch nail extraction operation | work between piers, it connects in order to fasten and fix the nut which screws a pedestal to a screw bolt. There is a drawback that the connecting surfaces of the piers are in close contact with each other, making it difficult to disassemble the formwork. In addition, the connecting tools used in large numbers have a large volume and are heavy, so that it is difficult to hang them on the waist and work.

Further, the formwork fixed to the wooden edge rib (38c) with screw nails (39b) or round nails shown in FIG. 9 (N) is advantageous in reducing transportation costs and storage after completion of construction on site. Therefore, the edge rib (38c) is removed from the weir plate (2), but the tip of the insulator bar (36b) is inserted between the weir plate (2) and the edge rib (38c), and the principle of the insulator is introduced. It takes time and effort to extract the screw nail (39b). Further, there is a disadvantage that the dam (2) and the edge rib (38c) are damaged by an impact when the tip of the insulator bar (36b) is inserted between the dam (2) and the edge rib (38c).

Therefore, recently, as shown in FIG. 9J, in order to improve the construction accuracy and construction efficiency, a cross section having a predetermined length is fixed to one side of a substantially L-shaped shape by a metal material. The countersunk bolts (39a) through-holes are provided at regular intervals in the one fixed piece, and the guide pin (41a) insertion holes are provided at regular intervals in the other fixed piece. The form frame which fixed the edge rib (38a) to the edge part of a dam plate (2) with the countersunk head bolt (39a) is used. However, the countersunk head bolt (39a) for fixing the weir plate (2) and the edge rib (38a), once used, a locking groove into which a locking part such as a screwdriver provided on the countersunk head bolt (39a) fits. Is buried in concrete, the idle rotation of the countersunk bolt (39a) cannot be prevented, and it is difficult to remove the weir plate (2). In view of this, a bolt has been proposed in which a piercing piece 6 that bites into the weir plate (2) is formed on the head of the bolt 5 to prevent idling. (For example, refer to FIG. 2 of Patent Document 7).

The connection between the molds is because the edge ribs (38a) included in the molds are strongly clamped by a connecting tool (40a) obtained by bending a round steel bar called a clip fitting shown in FIG. 9 (J). There is a drawback that it becomes difficult to disassemble the mold because the connecting surfaces of the edge ribs (38a) to be connected are in close contact with each other. Therefore, in order to facilitate disassembly of the formwork, as shown in FIG. 9M, an edge rib made of aluminum in which a space is provided in the central portion of the connecting surface between the connecting edge ribs (38b) and the contact surface is reduced. (38b) has been developed.

Since the connector (40a) obtained by bending the round bar steel is heavy, it is difficult to hang it on the waist and use it. Therefore, a connector made of synthetic resin, in which a guide pin, an arm, and a sandwiched portion are integrally processed, has been proposed. ing. (For example, refer to Patent Document 3.)

The above-mentioned weir board (2) is generally about 1800 mm in length and about 600 mm in width and about 12 mm in thickness. Has been.

Marui Sangyo Co., Ltd. (Marui Construction Parts General Catalog No. 71, page 71, piercing clamp)

The present invention provides a panel form mold (1) and a connecting tool (20) for facilitating the work of assembling and disassembling a form for forming concrete. The conventional form is shown in FIG. In order to improve the construction accuracy and construction efficiency as shown in Fig. 1, one side of the fixed piece with a cross section having a predetermined length made of a metal material and having a substantially L-shaped one side as a fixed piece and the other side as a connecting piece A countersunk plate (2) is provided with edge ribs (38a) provided with countersunk bolts (39a) through holes at regular intervals and guide pins (41a) insertion holes at regular intervals on the other connecting piece. A formwork is used in which the connection surfaces of the (cut face) and the edge rib (38a) are aligned and fixed with a countersunk head bolt (39a) or a tapping screw. However, in the connection of the formwork, the edge ribs (38a) to be connected are strongly sandwiched by the connecting tool (40a) shown in FIG. The ribs (38a) are in close contact with each other, and there is a defect that makes the mold disassembly work difficult. Therefore, it is an object to provide a gap between the edge ribs (38a) and to connect the edge ribs (38a) by pressing them with a hexagon bolt.

Further, in the conventional mold, the end portion of the edge rib (38a) may be deformed in a wave shape due to an impact caused by the work of disassembling the mold, and the connecting tool (40a) is difficult to be fitted in the expanded portion due to the deformation. There were difficulties.

Furthermore, since the slat (2) deteriorates due to the frequency of use of the mold, the slat (2) is periodically replaced, but the slat (2) and the edge rib (38a) are fixed. When the countersunk head bolt (39a) is used once, the locking groove of a screwdriver such as a screwdriver is filled with concrete, and the countersunk head bolt (39a) cannot be prevented from rotating, making it difficult to rotate the nut. . For this reason, it is an object to make the nut rotation work easy by the fixing bolt (29) which is fixedly fixed to the dam plate (2) and stops idling.

Furthermore, since the connecting tool (40a) called the clip metal fitting is heavy and has a large volume, it is difficult to work with the connecting tool (40a) used in large numbers on the waist. Further, as shown in FIG. 9K, in the connecting work of the metal edge ribs (38a), the guide pins (41a) are inserted into the guide pin (41a) insertion holes provided between the edge ribs (38a). (41a) With the arm (41b) in a horizontal state, the guide pin (41a) is inserted, and then the edge ribs (38a) are clamped together so as to be attached to the end of the arm (41b). When hitting the landing portion (41c) with a hammer, noise due to clapper, clapper and metal sound is generated, which may be a pollution problem, and it is difficult to use in a residential area.

Therefore, as shown in FIGS. 2 and 5, the guide pin (21) is inserted into the insertion hole (10) for inserting the guide pin (21) between the edge ribs (3) to be connected, and the inserted guide pin (21). A locking pin (24) is inserted into a through hole (23) provided in the tip end portion (22a), and a hexagonal bolt (27) is screwed into the rear end shaft of the guide pin (21). The bolts (27) were tightened to fix the edge ribs (3) to reduce the weight and prevent noise.

In the formwork in which the plate (2) and the wooden edge rib (38c) are fixed by the screw nail (39b) or the round nail shown in FIG. 9 (N), the plate (2) after completion of construction. Since it is difficult to pull out the nail for removing the wooden edge rib (38c) fixed to the board, the board (2) and the wooden edge rib (38c) are transported in a fixed state. Thereby, there existed a fault that conveyance work and packing storage became disadvantageous by the relationship of volume. Therefore, as shown in FIG. 2 (C1), the fixing bolt (29) is used as an object for facilitating separation of the dam plate (2) and the edge rib (38c).

As shown in FIG. 10, the conventional form for entering sumi is composed of a panel form (1) and a base plate (2), and a base part (2) of a base plate (2) having a width of about 150 mm. An L-shaped steel (42) is fixed to the corner portion) side by a countersunk head bolt (39a), and a connecting edge rib (38a) having a substantially L-shaped cross section at the opposite end of the fixing. ) Is realized. As shown in FIG. 3, by fixing the joining rib (4) to the joining of the entering summit portion (corner portion), the slat plate (2) having a width of about 150 mm and the edge rib (38a) The problem was to eliminate the need for

In a building construction site, the formwork is often carried or hand-held, and the edge rib (3) connecting piece as shown in FIG. 2 (A) or (B) in order to make the formwork lighter as much as possible. The problem was to form a reinforcing edge (8) at the end of (7), increase the section modulus of the edge rib (3), thereby reducing the thickness and reducing the formwork.

In the panel form frame (1) and the connector (20) thereof according to the present invention, the panel form frame (1) (the panel form frame (1) may be referred to as a form frame). As shown in FIG. 2, a plywood (2) end of the wood plywood or synthetic resin (wood plywood or synthetic resin plate or the like is also referred to as a control panel) and the above-mentioned pegs (2) are about 12 mm thick. In order to facilitate the connection, the insertion holes (10) for inserting the guide pins (21) are formed at a regular interval (for example, holes 13Φ150 pitch), or a substantially L-shaped edge rib (3) or a rectangular shape. A wooden edge rib (3c) is fixed to the end of the dam plate (2).

As shown in FIG. 2, the connector (20) for connecting the panel form mold (1) has a substantially L-shaped edge rib (3) provided in the panel form mold (1) to be connected. ) Or guide pins (21) provided between the rectangular wooden edge ribs (3c), and the cores of the insertion holes (10) are made to coincide with each other and fixed at the same time.

There are three types of edge ribs provided in the panel form frame (1): a synthetic resin edge rib (3), a metal edge rib (3), and a wooden edge rib (3c). Yes, the proper use is determined by the installer or the designer according to the use of the structure or the construction content.

The panel form (1) using the synthetic resin edge rib (3) or the metal edge rib (3) according to the present invention shown in FIG. The fixing bolt through-hole (11) is formed in the fixing piece (5) on one side, in which the cross section having a predetermined length is substantially L-shaped and one side is the fixing piece (5) and the other side is the connecting piece (7). ) Are formed at regular intervals, and a reinforcing edge (8) projecting in the same direction as the fixed piece (5) is formed at the end of the other connecting piece (7), and the connecting piece (7) And an edge rib (3) in which insertion holes (10) for inserting guide pins (21) are formed at regular intervals (for example, holes 13Φ150 pitch), and a mold as shown in FIG. The position where the edge of the slat (2) is left a little to avoid the edge ribs (3) that are connected when the frame is disassembled from being pressed against each other at the contact part (37) In other words, the crest plate (2) having a fixing hole (31b) for fixing the edge rib (3) at a position slightly apart from the joint portion (28) of the cuff plate (2), and the head having a substantially truncated cone shape. A fixing bolt (29) formed by forming a substantially pyramid-shaped wedge-shaped fixing portion (31a) below the portion (30) and forming a male screw on the lower shaft portion (32) of the fixing portion (31a); As shown in FIG. 4 (E2), the fixing bolt through hole (11) provided in the edge rib (3) and the fixing hole (31b) provided in the dam plate (2) are matched, The fixing bolt (29) is inserted from the side of the dam plate (2), hammered with a hammer or the like to fix the fixing bolt (29), and the nut (33) is screwed onto the fixing bolt (29). Thereby, it becomes possible to provide a clearance gap between the said edge ribs (3) to connect. Further, since the fixing bolt (29) is used to fix the weir plate (2) and the edge rib (3), the fixing bolt (29) is not idle, and the nut (33) can be easily rotated.

The panel form frame (1) shown in (A1) of FIG. 2 is attached to the edge rib (3) fixed to the back surface of the board (2) when the board (2) and the edge rib (3) are fixed. A tapping screw (29a) is inserted into the fixing bolt through hole (11) provided, and is fixed by tightening with a screwdriver. As a result, there is a feature that no trace of the fixture remains on the concrete surface. Moreover, since the tapping screw (29a) is a ready-made product, it is inexpensive and easily available.

As shown in FIG. 2, the edge rib (3) fixed to the panel form frame (1) and the plate (2) is fixed to the end of the connecting piece (7) of the edge rib (3). ), The end of the connecting piece (7) is strengthened by forming the reinforcing edge (8) protruding in the same direction. Thereby, since a section modulus becomes large, the thickness of the said edge rib (3) is made thin, and the weight of a panel form frame (1) is made light.

The panel form frame (1) provided with the wooden edge rib (3c) according to the present invention shown in FIG. 2 (C) has a rectangular cross-section having a predetermined length and a fixed piece on one side. (5), the other side is the connecting piece (7), and the other side connecting piece (7) is provided with insertion holes (10) for inserting guide pins (21) at regular intervals (for example, holes 13Φ150 pitch). 8 comprising a wooden edge rib (3c), a screw nail (29c) for fixing the edge rib (3c) to the weir plate (2), and the weir plate (2), (H) As shown in an example, in order to avoid the edge ribs (3c) that are connected at the time of mold form dismantling from pressing against each other at the abutting portion (37), the position where the end of the dam plate (2) is left a little, In other words, the edge rib (3c) is aligned with the position slightly separated from the joint (28) of the weir plate (2), and the weir plate 2) driving the screw nails (29c) from the side to fix. Thereby, a clearance gap can be provided in the said panel form mold (1) connection part to connect two or more. Therefore, the mold disassembly work is facilitated by providing the gap.

The panel form frame (1) provided with the wooden edge rib (3c) according to the present invention shown in (C1) of FIG. 2 is fixed to one side having a predetermined length and a substantially rectangular cross section. (5), the other side is a connecting piece (7), fixing bolt through holes (11) are drilled at a fixed interval on one side fixing piece (5), and a guide is provided on the other side connecting piece (7). A wooden edge rib (3c) formed by inserting insertion holes (10) for inserting pins (21) at regular intervals, and an edge rib (3) when disassembling the mold as shown in FIG. 3c) In order to avoid pressing each other at the abutting portion (37), the end of the slat (2) is slightly left, in other words, slightly apart from the joint (28) of the slat (2). The crest plate (2) having fixing holes (31b) for fixing the edge rib (3c) at positions at regular intervals, and a substantially frustoconical head (3 0) A fixing part (31a) having a substantially truncated pyramid-shaped wedge shape is formed below, and a fixing bolt (29) formed by forming a male screw on the lower shaft part (32) of the fixing part (31a) is provided. As shown in (E2), the fixing hole (31b) provided in the dam plate (2) and the fixing bolt through hole (11) provided in the edge rib (3c) are matched to each other, and the dam plate ( 2) The fixing bolt (29) is inserted from the side and struck with a hammer or the like, and the fixing bolt (29) is fixedly fixed and screwed onto the nut (33). That is, it is almost the same as the panel form (1) shown in FIG. 2C, and the difference is that a screw nail (29c) as a fixing tool is used as the fixing bolt (29). As a result, the fixing bolt (29) is fixedly fixed to the dam plate (2), so that the fixing bolt (29) is not idle and the nut (33) can be rotated easily. Further, by removing the edge rib (3c) from the weir plate (2), the volume becomes about 1/3, which is advantageous in carrying work and packing storage. Further, the fixing bolt (29) fixed and fixed to the dam plate (2) can be easily removed by tapping the end of the fixing bolt (29) with a plastic hammer or the like, and can be reused. is there.

The panel form frame (1) used for the entrance smear part (corner part) shown in FIG. 3 has a central piece having a substantially U-shaped cross section having a predetermined length made of a synthetic resin material or a metal material. (6), fixing bolt through holes (11) are drilled at regular intervals in the fixing piece (5) on one side, the fixing piece (5) on one side and the connecting piece (7) on the other side, A reinforcing edge (8) projecting in the same direction as the main body (6) is formed at the end of the other connecting piece (7), and a guide pin (21) is inserted into the connecting piece (7). Holes (10) are drilled at regular intervals, and furthermore, to prevent the connecting piece (7) from being pushed by the adjacent edge rib (3) or the wooden edge rib (3c) when the mold is disassembled. The joining rib (4) provided with the protruding portion (9) slightly extending from the main body portion (6) is connected to the end of the dam plate (2). The combined outer surface (the side in contact with the concrete) of (small surface) and the joint ribs (4) the body portion (6), fixed by a fixing bolt (29). Thus, the panel forming mold (1) is used to fix the joining rib (4) to the entering summit portion (corner portion) of the baffle plate (2). ) Is realized. That is, the fixing piece (5) on one side of the joining rib (4) is fixed to the dam plate (2), the connecting piece (7) on the other side of the joining rib (4), and the counterpart panel type By joining and fixing the connecting piece (7) of the edge rib (3) or the wooden edge rib (3c) provided in the frame (1), the joining of the entering sumi portion (corner portion) and the edge rib (3) Realize the connection. Thereby, there exists the characteristic which can use the same joining rib (4) for joining of a wall form frame and a slab form frame, or joining of a wall form frame and a wall form frame.

The fixing bolt (29) according to the present invention shown in FIG. 4 forms a substantially pyramid-shaped wedge-shaped fixing portion (31a) below the substantially truncated cone-shaped head (30), and the fixing portion (31a) below. A male screw is formed on the shaft (32). As a result, the fixing bolt (29) is fixed to the base plate (2) by inserting the fixing bolt (29) into the fixing hole (31b) provided in the base plate (2) and hitting it with a hammer or the like. Fix it. Therefore, the rotation of the nut (33) is facilitated, so that the nut (33) of the fixing bolt (29) is left in a state in which the slat (2) is left after placing the concrete as shown in (H) of FIG. It is possible to rotate a plurality of connected panel foam frames (1) by removing the edge rib (3c) on one side, thereby inserting the guide pin (21) insertion hole (10 on the other edge rib (3c). ), The tip of the insulator bar (36b) is inserted, the support base (36a) is placed on the bottom plate (2) from which the edge rib (3c) has been removed, and the insulator bar (36b) is placed on the support base (36a) as a fulcrum. The panel form (1) can be easily peeled by pressing the rear end. From the second sheet, the first edge rib (3c) removed first is returned to its original position, the tip of the insulator bar (36b) is inserted into the guide pin (21) insertion hole (10), and the concrete surface (43) is inserted. By pressing the rear end of the insulator bar (36b) at the fulcrum, the panel form (1) can be easily peeled off. In addition, since the fixing portion (31a) of the fixing bolt (29) is formed in a substantially truncated pyramid-shaped wedge shape, the fixing bolt (29) can be easily removed without being damaged many times. There is a feature that can be reused.

The connector (20) according to the present invention shown in FIGS. 5 and 2 is formed by forming a taper with a small tip at the tip (22a) of the cylindrical tube having a predetermined length by a synthetic resin material or a metal material. A through hole (23) for inserting the locking pin (24) into the tip end portion (22a) is drilled, and a female screw to which a hexagon bolt (27) is screwed is formed at the rear end portion of the cylindrical tube. The guide pin (21), the head (30) for locking the turning tool, the hexagonal bolt (27) having a locking portion such as a locking groove or a hexagonal hole, and an iron wire of about 4 mm are roughly shown. A locking pin (24) that is bent into a P-shape and has a taper that reduces the tip of the curved P-shape, and a movable member provided at the rear end of the guide pin (21) (25) or a round washer (26), on the panel formwork (1) Inserting the guide pin (21) into the insertion hole (10) for inserting the guide pin (21) provided between the wooden edge ribs (3c) or the edge ribs (3), and inserting the guide pin (21) Hexagon bolt screwed through the movable member (25) or round washer (26) provided at the rear end of the guide pin (21) by inserting the locking pin (24) into the emerging through hole 23 When rotating (27), the movable member (25) or the round washer (26) moves forward, and the slats (2) fixed to the wooden edge ribs (3c) or edge ribs (3). , The hexagon bolt (27) stops rotating, and the connection and fixation are realized in a state where the edge ribs (3c) or the gaps between the edge ribs (3) are held. Thereby, the joining property of the weir plates (2) is improved. Moreover, the formwork dismantling work is facilitated.

Further, the connecting tool (20) has a weight and volume of about 1/3 compared to the conventional connecting tool (40a) shown in FIG. Making it easier to work with. Moreover, since the connection work of metal edge ribs (3) provided in the panel form frame (1) by using the connection tool (20) hardly generates noise, it is useful for noise prevention.

Further, the connector 20 has a feature that the allowance (21t) can be widened or narrowed within a certain range by moving the movable member (25) or the round washer (26) forward and backward. Further, since the hexagon bolt (27) is screwed into the cylinder of the guide pin (21), the thread portion does not appear on the surface of the guide pin (21), so that the insertion hole for inserting the guide pin (21) is inserted. (10) The sliding with the side surface is good, and the guide pin (21) can be easily removed when the mold is disassembled. In addition, since the guide pin (21) can be easily removed, the movable member (25) can be replaced to connect a steel formwork or the like called a metal foam that has been used frequently.

The connector (20) made of synthetic resin pulls out the guide pin (21) inserted into the guide pin (21) insertion hole (10) between the edge rib (3) or the wooden edge rib (3c) to be connected. The tip of the guide pin (21) may be hit with a plastic hammer or the like, and it is desirable to protect the tip with the buffer member (22b). Further, the use of the movable member (25) or the round washer (26) is not particularly limited, and either one may be used. (For example, if a round washer (26) is used, the movable member (25) is unnecessary.)

A panel form frame (1) according to the present invention has a substantially truncated pyramid shaped wedge-shaped fixing portion (31a) formed below a substantially truncated cone-shaped head portion (30), and the lower shaft portion of the fixing portion (31a). The fixing bolt (29) for fixing the dam plate (2) and the edge rib (3) or the wooden edge rib (3c) by the fixing bolt (29) in which the male screw is formed on (32) is used as the dam plate (2). Since it is fixed and fixed to the surface, it will not rotate freely. This speeds up the attaching or removing operation of the edge rib. Moreover, by removing the edge rib from the dam plate (2), the volume becomes about 1/3, which is advantageous in carrying work and packing storage.

Moreover, since it is possible to rotate the nut (33) of the fixing bolt (29) with the siding plate (2) left after the concrete is solidified, a plurality of connected panel forms as shown in (H) of FIG. Remove the edge rib (3c) on one side of the mold (1), insert the tip of the insulator bar (36b) into the guide pin (21) insertion hole (10) provided on the other side edge rib (3c), The panel form frame (1) can be easily peeled by pressing the rear end of the insulator bar (36b) with the dam (2) from which the edge rib (3c) on one side is removed as a fulcrum. From the second sheet, the first edge rib (3c) removed first is returned to its original position, the tip of the insulator bar (36b) is inserted into the guide pin (21) insertion hole (10), and the concrete surface (43) is inserted. By pressing the rear end of the insulator bar (36b) at the fulcrum, the panel form frame (1) can be easily separated. This facilitates and speeds up the formwork disassembly work. In addition, damage to the panel form (1) is reduced, and the number of diversions is increased.

The connector (20) shown in FIG.5 and FIG.2 is for inserting the guide pins (21) provided between the wooden edge ribs (3c) or the edge ribs (3) provided in the panel form frame (1). The guide pin (21) is inserted into the insertion hole (10), and the locking pin (24) is inserted into the through hole 23 that appears as a result of the insertion, and is provided at the rear end of the guide pin (21). When the hexagon bolt (27) screwed through the movable member (25) or the round washer (26) is rotated, the movable member (25) or the round washer (26) moves forward, and the wooden edge When the slats (2) fixed to the ribs (3c) or the edge ribs (3) are brought into contact with each other, the rotation of the hexagon bolt (27) stops and the gap between the edge ribs is maintained. Since it is connected and fixed, the formwork dismantling work is facilitated. In addition, since it is possible to adjust the gap (21t) shown in FIG. 5 within a certain range, a steel mold called a metal foam that has been frequently used by replacing the movable member (25). Etc. can also be used for connection. Furthermore, as compared with the conventional connector (40a) shown in FIG. 9, the volume and weight are reduced to about 1/3, and it becomes easy to hang many used connectors (20) on the waist.

In recent years, housing damage due to storms, earthquakes, fires, tsunamis, etc. has been conspicuous, and the Great East Japan Earthquake has caused serious problems such as rubble crossing the Pacific Ocean. For this reason, RC (steel reinforced concrete) rigidly-attached detached houses with a fireproof structure that is not flowed by water have been evaluated from the wooden structure. However, it is difficult for RC detached houses to spread due to the lack of formwork carpenters, which is an important task. Therefore, the formwork assembling work and the disassembling work are facilitated and expedited by a combination method in which the panelform formwork 1 and its connector 20 can be easily connected to each other. This will be useful for future disaster prevention housing or reconstruction housing after the Great East Japan Earthquake.
