Description

  The present invention relates to a mold for forming a reinforced concrete structure, a slide method for constructing a concrete mold fixing and fastening structure, a concrete mold and a series of connected concrete unit molds, and transferring them to the upper floor. More specifically, the present invention relates to a new structure that can more easily carry out a continuous work of concrete molds, or a new component that is used to construct a concrete unit mold.

In concrete structures, when placing concrete during the construction of the frame, reinforcing ribs serving as reinforcements are used as the framework of the structure, and on both sides, vertical ribs, intermediate ribs, and upper and lower edge ribs are attached to the slats. The built-in concrete formwork (hereinafter sometimes simply referred to as formwork) is united by connecting them to each other. At this time, the formwork is maintained at the required interval between the opposing concrete formwork. Form tie (registered by Okabe Co., Ltd.) with a round bar-shaped separator placed on top and a screw rod to be mounted on the seat plate on the butter material clamping part, which is a concrete mold clamping bracket used in combination with the round bar-shaped separator. Trademark) (hereinafter simply referred to as foam tie), the opposing concrete formwork is fastened, and the concrete mold is placed when the concrete is placed. Concrete that is constructed by rotating and pressing and fixing the nuts screwed into the thread 杆 of the foam tie while arranging the upper and lower horizontal butter material that supports the back of the concrete form so as to support the load acting on the concrete Concrete structures are constructed by supplying (pouring) concrete between formwork units.

When constructing the above-described concrete formwork as a unit, the outer wall or the like whose upper and lower layers are coplanar generally has a gap of 250 mm or less (see, for example, Non-Patent Document 2) between the wall surface of the frame and the temporary scaffolding. Because it is designed and there is no space for temporary storage such as horizontal flaps when disassembling or assembling the formwork that moves to the upper floor, it is easy to assemble the concrete formwork by handing it up to the upper floor at the same time as disassembly. This method is generally used.

In addition, on the outer wall with the same level in the upper and lower layers, the inner (indoor) side formwork is preceded in order to omit the installation work of the butterfly angle, which is the base material for receiving the external concrete formwork. The upper and lower horizontal material that supports the concrete load by attaching the outer formwork one by one to the separator fixed to the concrete formwork on the inner side in accordance with the hole of the outer formwork siding plate. Is used, and a method of pressing and fixing using a foam tie is adopted. However, in this method, since the entrance and exit of the concrete form follows the internal form, it is easy to cause a difference (step) in the joint part. . In addition, because the space for temporary horizontal material is difficult, the horizontal material is temporarily placed on the scaffold work floor or scaffold work passage, which not only causes problems in ensuring safety during work, but also improves work efficiency. Also decreases. For this reason, the so-called concrete unit form slide method, in which a plurality of concrete forms are connected and unitized into a single unit, is lifted and moved (slid) directly to the upper floor, is attracting attention. Became.

In the installation of the butterfly angle, which is the spread material that receives the formwork related to the slide method of the concrete formwork that has been proposed in the past, after the concrete formwork has been removed, the concrete is placed with a round bar separator that is left at the top. A fastening bracket is screwed onto a thread portion protruding from the surface, and a step tie (registered trademark of Okabe Co., Ltd.), which is a butterfly holding bracket that is a spread sheet material that receives a formwork, is fastened by the fastening bracket. Tighten and fix the butter angle while adjusting the vertical position of the press bracket so that the upper end surface of the butter angle supported by the press bracket matches the top end of the cast slab, and then the concrete mold Slide the frame from the lower floor and lift it, place it on the butterfly angle, adjust the misalignment of the placement surface in the horizontal direction and arrange it on the butterfly angle, which is a spread butterfly material, on nails, scissors, etc. The concrete formwork is positioned and fixed, and then, a round bar separator is inserted into the arranged concrete unit formwork, and a foam tie is screwed onto the shaft foot of the round bar separator. In general, a method of fastening the concrete unit formwork with the foam tie while arranging materials is generally used.

In addition, in order to improve the installation method of the flap angle which is a spread material that receives the concrete formwork, a cut part is provided in the lower part and upper part of the slat plate in a series of concrete unit formwork, and the part can be attached and detached. In other words, a certain range of the upper and lower sides of the formwork can be removed from the vertical ribs (such as piers), and this can be removed when the formwork is disassembled after placing concrete. After separating the horizontal board in the lower part of the concrete unit formwork that has been slid to this part, separating the upper horizontal board part of the possible horizontal board and leaving it on the concrete casting surface, While fixing the formwork by abutting against the left horizontal plate, it is integrated by assembling the lower horizontal plate as the upper horizontal plate, and this is divided into each layer. Return slide method has been proposed Ri. (For example, refer to Patent Document 1.)

Also, in some cases, in the construction method of a series of concrete unit formwork, when constructing a concrete unit formwork, a temporary work scaffold is constructed along the frame surface of the outer wall, etc. whose upper and lower layers are the same surface, but it prevents fall. Since the clearance between the frame wall and the scaffold is 250 mm or less in order to guarantee the safety of the side, the width of the horizontal butter material that supports the load of cast concrete acting on the formwork that is the formwork material It is difficult to secure a temporary space. For this reason, after placing concrete, a temporary placement metal fitting for the formwork butterfly (product name) is fixed to the concrete unit formwork. In order to separate the formwork to be connected to the placing portion, the upper and lower horizontal butterfly materials are removed. After digits, and advantages that moving lifting just above floor with concrete unit formwork one side, the temporary-placed device has been proposed in the mold for Bata material. (For example, see Patent Document 3.)

However, when supporting the concrete unit formwork in the first concrete unit formwork slide method described above, the butterfly angle, which is the flooring material that is attached to the holding bracket, is connected to the top edge of the existing cast concrete that is the foundation. In order to adjust the level, it is necessary to adjust the vertical position of the pressing metal fittings for each level, and it takes time to pass through a single concrete formwork and fix it to the butterfly angle. Since the concrete formwork is connected to the joint part of the concrete formwork and the butterfly angle which is the laying butter material, it is fixed or reassembled using nails, scissors etc. for each level, Damage to the formwork will occur, and it will take time and money to repair it.

Further, in the second concrete unit formwork slide method, it involves a complicated work of separating separable horizontal slats provided in the upper and lower parts of the concrete unit formwork or alternately incorporating them. And has the disadvantage that the structure of the concrete formwork is complicated.

Furthermore, in the transfer of the upper and lower horizontal material in the third concrete unit formwork slide method, the horizontal material was temporarily deposited in a temporary placement metal fitting for the formwork attached to the concrete unit formwork. After that, it is a method to slide the horizontal butter material together with the concrete unit formwork, which is effective in omitting the labor of transferring the horizontal butter material. On the other hand, when using the horizontal butter material once deposited , It will take time to work from returning to the required place.

In addition, when fastening the upper and lower horizontal material that supports the back of the concrete formwork in the concrete unit formwork slide method, the shaft foot part of the cone cup attached to the round bar separator is formed on the concrete unit formwork plate. The horizontal tie material is pressed and fixed by screwing the foam tie into the insertion hole of the separator and the shaft foot part of the cone cup to be attached to the round bar separator protruding from the concrete surface is Since it is difficult to remove the mold by entanglement with the frame slats, a separate shaft foot separator for allowing the shaft foot portion of the cone cup to be separated is connected by screwing, and the concrete formwork is left in the state where the shaft is left. A method is adopted in which the foot separator is removed with a screwdriver tool or the like to facilitate demolding. However, in order to remove the shaft foot separator, the foam tie which becomes an obstacle is released. Therefore, there is a drawback that the horizontal butter material must be moved once.

Furthermore, in the above-described foam tie, the shaft foot of the cone cup attached to the round bar-shaped separator is inserted into the separator insertion hole formed in the concrete formwork, and the foam tie is screwed together. Tighten the nut to fasten the upper and lower horizontal material. If the foam tie is located near the center of the vertical rib or intermediate rib of the concrete formwork, the nut will be overtightened. In order to prevent the deformation of the formwork siding plate from the upper and lower horizontal butter material, it may be deformed into a curved shape. A spacer for preventing the deformation of the dam plate has been proposed. (For example, refer to Patent Document 4.) In order to omit the spacer as another method, a stopper member is fixed to a position defined by a screw rod which is a butter material fastening portion of the concrete mold fastening metal fitting, Concrete form clamps that restrict over tightening of the fence have been proposed. (For example, refer to Patent Document 5.)
JP-A-10-317668 Japanese Utility Model Publication No. 06-008377 Japanese Patent Application Laid-Open No. 09-291701 Japanese Patent Laid-Open No. 2005-171662 JP 2005-61126 A JP 2006-207367 A Published by Okabe Co., Ltd. “Product Catalog NO3 Concrete Form” Issued by the Construction Safety Center Co., Ltd.

The present invention has been made in view of the above-described points. In order to rationalize the construction work of the concrete unit formwork in the construction of the concrete unit formwork, the upper and lower layers of the case have the same wall surface as the outer wall. The concrete formwork assembly and disassembly work is complicated because it is difficult to secure a temporary storage space for formwork materials, such as the gap between the building and the temporary scaffolding is designed to be 250 mm or less to ensure the safety of falling prevention. For this reason, we provide concrete unit formwork slide construction method that moves all together to eliminate the complexity of assembling and disassembling concrete formwork, and new metal fittings used to construct concrete unit formwork. To do.

In the configuration of the concrete unit formwork slide construction method according to the present invention for solving the above-mentioned problems, a concrete unit formwork is constructed on the outer wall or the like whose upper and lower layers are the same surface, and after placing the concrete, This is a slide transfer method, in which the slab-drawing separator or plate-like separator at the top of the already-placed part is left, and a concrete unit formwork support bracket for receiving the formwork is fastened to this separator. The concrete unit mold is slid and placed on the support bracket of the concrete unit mold, and the concrete unit mold is placed on the surface of the concrete frame placed by the fastening bracket provided on the support bracket of the concrete unit mold. This lies in that the lower end of the frame is pressed and sandwiched.

In addition, the hanging bracket is fixed at an appropriate position on the lower end of the concrete unit formwork, and on the other hand, a guide fitting that guides the sling rope corresponding to the hanging bracket is fixed at an appropriate position on the upper end, In the uppermost part of the already placed concrete placement part, a skid metal fitting for stably guiding the concrete unit formwork is attached, thereby improving the safety of the concrete unit formwork lifting work.

In addition, the horizontal butterfly material holding bracket that surrounds and accommodates the upper and lower horizontal flaps that support the concrete load placed on the back of the concrete unit formwork is attached to the vertical ribs or intermediate ribs of the concrete unit moldwork, The horizontal butterfly material is lifted together with the concrete mold and slid and moved while holding the material in the vicinity of the mounting position.

In the support bracket of the concrete unit formwork according to the present invention, it is for receiving and fixing the lower end portion of the concrete unit formwork, and a separator or plate for slab pulling left on the uppermost part of the already placed concrete A fixing leg that is fastened by a fastener that is connected to the separator, and includes a fastener that can be moved forward and backward to press and hold the lower end portion of the concrete unit formwork at the upper part of the fixed leg. With the concrete placement surface of the base as a reference, smoothness is maintained by the operation of fixing the formwork, it is possible to prevent mistakes in the concrete joining surface, and it has the effect of improving construction accuracy and construction efficiency It exists.

In the concrete form clamp fastener according to the present invention, a U-shaped connecting member that is inserted into and connected to a slab pulling separator or plate separator is formed on the slab pulling separator or plate separator. A slit-like through hole is formed to match the slit-like through hole, and a nut is attached to the rear part of the connecting member formed by inserting and connecting a wedge through a seat plate for pressing and fixing the upper and lower horizontal flaps. A screw rod formed by screwing is fixed, and the upper and lower horizontal butterfly members are pressed and fixed by rotation of a nut screwed to the screw rod.

Further, in the above-described connecting member, a separator or plate for slab pulling entangled with a concrete formwork siding plate in a state in which the upper and lower horizontal butter material is stored in the horizontal butter material holding metal fitting that accommodates the upper and lower horizontal butter material. Slab pulling separator or plate separator inserted in the concrete formwork slab so that the unnecessary part of the sheet separator can be twisted off from the fractured part formed at a position where it does not protrude from the concrete surface It is necessary to align the hole core with the axis of the slab pulling separator or plate separator. Therefore, the tip of the connecting member bent into a U shape to be connected to the slab pulling separator or plate separator. Provided with a bearing portion formed in a bowl shape so as to be fitted into the insertion hole of the separator for pulling the slab or the plate-like separator, and the shaft A washer to be engaged with the step portion of the hook portion is fitted, and the bearing portion is inserted into a slab pulling separator or a plate-like separator insertion hole drilled in the concrete formwork plate, and a slab pulling separator or By connecting to the plate separator, the slab pulling separator or the axis of the plate separator is supported by the slab pulling separator or the insertion hole of the plate separator, so that the slab pulling separator or the plate separator Rotation of the slab pulling separator or the unnecessary part of the plate separator can be rotated and twisted in a state where the concrete formwork plate is left behind.

In addition, if the concrete mold fastening bracket is positioned near the center between the vertical ribs or intermediate ribs of the concrete mold, the concrete formwork siding plate may be moved up and down by the side of the horizontal flap In order to prevent such deformation, the distance between the washer provided on the bearing part of the concrete formwork connecting part and the wedge is affected to affect the concrete formwork plate. In other words, in the state where the upper and lower horizontal flaps are pressed and fixed, the contact point where the washer abuts against the concrete formwork and the contact where the wedge contacts the upper and lower horizontal flap member, that is, the distance between the contacts However, by forming it so as to be equal to the expected dimension of the vertical rib or intermediate rib (L in the figure), the wedge is received by the wedges through the upper and lower horizontal flaps. In which resides in that so as not to affect the concrete form dam since.

In the horizontal butterfly material holding metal fitting according to the present invention, the upper and lower horizontal butterfly members are separately supported so as to divide the space on the U-shaped surrounding member having a space portion for accommodating the upper and lower horizontal butterfly materials. The horizontal butter material holding metal fitting provided with an intermediate receiving material and provided with fixing holes or clamping fasteners for fixing to the vertical ribs or the intermediate ribs of the concrete mold on the upper and lower legs of the surrounding member. Then, it is inserted into the upper and lower horizontal flaps fixed by the concrete mold clamps and fixed to the vertical ribs or intermediate ribs of the concrete unit mold. Thus, after curing of the placed concrete is completed, the upper and lower horizontal butter material is released from tightening so that it is stored in the upper and lower horizontal butter material holding metal fittings.

In the concrete unit mold slide method according to the present invention, in order to make it possible to adjust the mounting position on the separator for slab pulling or the plate-like separator as a support fitting for the concrete unit mold receiving the concrete mold. The slab pulling separator or the fixed leg portion straddling the plate-like separator is provided with a reciprocating fastening bracket in such a form that the lower end portion of the concrete unit mold is pressed and held against the concrete frame surface. Thus, the supporting portion of the concrete unit mold can be easily and reliably configured. As a result, construction accuracy and construction efficiency are improved.

Also, when the concrete unit formwork constructed integrally after concrete placement is slid to the upper floor, the slab pulling around the concrete unit formwork plate is made easy to separate and remove the concrete unit formwork. Therefore, when the concrete form clamp fastening metal is released by using the horizontal butterfly material holding bracket, the upper and lower horizontal butterfly material is replaced by the horizontal butterfly material holding bracket. Therefore, separation and demolding of the concrete unit formwork are facilitated by removing unnecessary portions of the separator for separating slabs or the plate-like separator entangled with the concrete unit formwork using a turning tool. In addition, when sliding the concrete unit formwork, it is possible to move it integrally with the concrete unit formwork while holding the upper and lower horizontal flaps in the vicinity of the mounting position, and to fasten the concrete unit formwork In some cases, it is possible to immediately perform the work of tightening the upper and lower horizontal flaps. As a result, on the temporary scaffolding, which is a high-place work, the work of dismantling the horizontal butter or returning (reassembling) it to the required place is omitted, so it is possible to ensure work safety and rational construction. It will be effective.

Further, when the concrete unit mold is slid, a hanging metal fitting is fixed at an appropriate position on the lower end of the concrete unit mold, and on the other hand, a hanging rope corresponding to the hanging metal fitting at an appropriate position on the upper end. On the other hand, by fixing a skid bracket that stably guides the concrete unit formwork to the uppermost part of the already-cast concrete frame, the lifting work during the sliding movement of the concrete unit formwork is fixed. Safety will be improved.

In the support bracket for the concrete unit formwork according to the present invention, when the concrete unit formwork is slid and fixed to the upper floor, the separator for slab pulling is left in the concrete placement part. Alternatively, the fastening bracket used in connection with the plate separator fixes the concrete unit mold support bracket that receives the concrete unit mold, and places the concrete unit mold frame on the concrete unit mold support bracket, The bottom end of the concrete unit formwork is pressed and clamped by the support brackets of the concrete unit formwork, making it easy to fix the formwork assembly, and adjusting the position of the concrete formwork, which previously required labor, The height direction and the connecting direction, that is, the surface that prevents the so-called misalignment of the formwork Since this work follows the existing concrete casting surface as a reference, it is possible to maintain smoothness by the operation of fixing the formwork, and it is possible to prevent mistakes in the concrete joint surface, and to improve construction accuracy and The effect which improves construction efficiency will be acquired.

In the concrete form clamp fastener according to the present invention, a wedge is inserted into a U-shaped connecting portion for inserting and connecting to a slit-like through hole provided in a plate-like separator or a separator for slab drawing. A screw rod formed by screwing a nut through a seat plate for pressing and fixing the upper and lower horizontal butter material is fixed to the rear part of the connecting member provided with a slit-like through hole for connecting together, A structure in which upper and lower horizontal butterfly members are pressed and fixed by nuts screwed into a screw rod, and a hook-shaped bearing for supporting the slab-drawing separator or the center of the plate-like separator at the tip of the connecting member Forming part. Thus, the bearing portion is fitted into a slab-drawing separator or plate-like separator by fitting the bearing portion into a slab-drawing separator or a plate-like separator insertion hole of the concrete formwork plate, thereby separating the slab-drawing separator. Alternatively, since the slab-drawing separator or the axis of the plate-like separator is supported by the insertion hole of the plate-like separator, the unnecessary portion of the slab-drawing separator or the plate-like separator entangled with the concrete formwork slab is removed from the concrete. It is possible to remove the thread from the slab-drawing separator or the rupture portion of the plate-like separator formed at a position where it does not protrude from the surface of the concrete frame in the state in which the formwork plate is left. As a result, the demolding work is simplified, so that the damage to the concrete formwork is reduced and the effect of increasing the number of diversions is obtained.

In addition, a long hole is formed in the lower portion of the wedge connected to the slab pulling separator or plate-like separator of the concrete mold fastening bracket, the horizontal butterfly material temporary catching metal is hooked and fixed, and the lower horizontal butterfly material is temporarily attached. By doing so, when constructing a concrete unit formwork, it is possible to safely and relatively easily install the horizontal butterfly material, which is a long object. A reasonable effect of construction will be obtained.

Further, a washer that is locked to a step provided on the bearing portion of the connecting member of the connecting member of the concrete mold fastening bracket is connected to a contact point that contacts the concrete formwork plate and a separator for slab pulling or a plate-like separator. The contact points where the wedges come into contact with the upper and lower horizontal flaps, in other words, the contact points of the washers that come into contact with the bottom plate and the contact points of the wedges that come into contact with the upper and lower horizontal flaps are the expected dimensions of the vertical ribs and intermediate ribs (in the figure) L). As a result, since the wedge receives the overtightening force of the screw rod through the upper and lower horizontal butter material, it does not affect the concrete formwork plate and forms a flat concrete surface to be defined. .

In the horizontal butterfly material holding metal fitting according to the present invention, the upper and lower horizontal butterfly members are separately supported so as to divide the space on the U-shaped surrounding member having a space portion for accommodating the upper and lower horizontal butterfly materials. The horizontal butter material holding metal fitting provided with an intermediate receiving material and provided with fixing holes or clamping fasteners for fixing to the vertical ribs or the intermediate ribs of the concrete mold on the upper and lower legs of the surrounding member. Then, it is inserted into the upper and lower horizontal flaps fixed by the concrete mold clamps and fixed to the vertical ribs or intermediate ribs of the concrete unit mold. As a result, after curing of the placed concrete is completed, the upper and lower horizontal butter materials are stored in the horizontal butter material holding metal fitting by releasing the fastening of the upper and lower horizontal butter materials. Slightly lift the upper horizontal material stored in the holding bracket to widen the gap between the horizontal materials, turn the tool into the part that protrudes from the slab separator or plate separator, and rotate it. It is possible to break from the rupture part of the separator for slab pulling or the plate-like separator, in other words, it is possible to remove from the rupture part provided at a position not protruding from the concrete housing surface. . As a result, by removing unnecessary parts of the separator or plate separator for slab pulling around the slab of the concrete unit formwork, the separability of the concrete unit formwork is improved and the demolding work is greatly improved. In both cases, there is no excessive impact at the time of demolding, so the damage is reduced, and the effect of increasing the number of diversions of the concrete formwork is obtained. Furthermore, in high-altitude work on temporary scaffolds where there is a high degree of danger, safety management and process management can be performed by eliminating the work of moving the upper and lower horizontal flaps, which are long objects, or returning them to the required locations (reassembling). The cost reduction of the construction cost due to the rationalization of the above etc. is also great, and a dramatic practical effect is obtained.

The concrete unit formwork slide construction method, the concrete unit formwork support metal fitting, the concrete formwork fastening metal fitting, and the horizontal flap material holding metal fitting according to the present invention will be described. This is a basic explanation of using a wooden concrete formwork 1 that has been frequently used in the past, but is not limited to this, and it is also possible to use a concrete formwork made of metal or synthetic resin. Please understand that.

Hereinafter, the concrete unit mold slide method according to the present invention and the parts or component fittings used in the concrete unit mold according to the present invention will be described. However, the present invention is not intended to be understood in a limiting sense. Design changes can be made without departing from the technical idea.

Further, the plate-like separator 2 used in the embodiment, and the receiving plate 3 and the cone cup 4 to be inserted into the plate-like separator 2 are those proposed by the present applicant in Japanese Patent Application Laid-Open No. 2006-207367. The plate-like separator 2 is a plate-like separator 2 that can be easily twisted and cut off by cutting off both end edges at the fractured portion 5 and missing the cross section.

Furthermore, a wooden board or a synthetic resin board 10 is fixed to the vertical rib 6, the upper and lower edge ribs 7, 8, and the intermediate rib 9 as a skeleton by a fixing member such as a screw or a nail. Because the damage or aging is severe with the frequency of use, it will be replaced regularly. Therefore, when the rib material is made of metal, it is difficult to fix with nails and the like, and a countersunk screw bolt is used. However, the driver's locking groove formed on the countersunk head has been placed. The locking groove cannot be used because it is filled with concrete, so the countersunk screw bolt cannot be locked, and when the nut is rotated, it rotates freely (co-rotation), and there is a part along the shaft part of the screw bolt part. By using a flat-headed countersunk screw bolt (not shown), the screw bolt can be prevented from spinning freely. Specifically, a shape in which a flat-headed screw bolt with a flat part of the screw bolt shaft is fitted Are fixed to the vertical rib 6, the upper and lower edge ribs 7, 8 and the intermediate rib 9, and the board 10 such as a wood plywood is fixed, so that the screw bolt can be rotated freely (co-rotation). It will be prevented, to permit sampling of the threaded bolts by rotating only the nut.

Furthermore, the concrete formwork is made of wood or metal, with vertical ribs 6 serving as a skeleton, upper and lower edge ribs 7 and 8 and intermediate ribs 9 and nails or screws on wooden boards or synthetic resin boards 10. However, the present invention is not limited to this, but is not limited to this. Alternatively, it is possible to use a metal form mold or the like.

The concrete unit formwork slide construction method according to the present invention shown in FIGS. 1 to 19 according to the present invention will be described. In the concrete unit formwork, as shown in FIG. The vertical rigs 6 are connected to each other by using appropriate fixing members such as nails, scissors, clip metal fittings, etc., and the concrete placement surface has a predetermined height position from the upper and lower edges. A pair of jointed ground rods 11 and 12 are fixed to each other, and at the lower end, a metal or wooden laid butter material 13 serving as a base for placing the concrete mold 1 to be connected is placed. Are fixed by screws or screw bolts, and the upper and lower horizontal butter materials 14, 15 such as round steel tubes or square steel tubes supporting the load of the concrete to be placed on the back side are strength gauges. It arranged based on, the horizontal flap member and fastened with a separator 16 or the plate-shaped separators 2 and concrete formwork Clamping fixture 17 for the slab pull for tightening a concrete unit formwork.

In addition, the concrete unit mold frame surrounds and accommodates the fixed upper and lower horizontal flaps 14 and 15, so that a substantially horizontal horizontal flap hold metal 18 is surrounded by a concrete mold so as to surround the horizontal flaps. It is attached and fixed to the vertical rib 6 or the intermediate rib 9 of the frame by an appropriate fixing means, for example, a fixing method such as a clamping / fastening hardware or a screw or a screw bolt. As a result, after curing of the placed concrete is completed, when the fastening of the horizontal butter material is released, the horizontal butter material holding metal fitting 18 is stored, and therefore the horizontal butter material 14, 15 is turned from the upper and lower gaps. 19 is inserted, and the slab pulling separator 16 or the plate-like separator 2 entangled with the concrete formwork board 10 is removed by threading from the fracture portion 5 formed at a position not protruding from the concrete surface. As a result, the separability between the concrete and the concrete unit formwork after placing the concrete is improved and the demolding is facilitated, and when the concrete unit formwork is slid, the upper and lower horizontal members 14 and 15 are in the vicinity of the mounting position. Therefore, it is possible to omit the work of disassembling and returning (reassembling) the upper and lower horizontal flap members 14 and 15 to the required place.

Further, a horizontal butterfly material holding metal fitting 18 that surrounds and accommodates the upper and lower horizontal rubber materials 14 and 15 that support the concrete load installed on the back surface of the concrete unit mold is provided at an appropriate position of the concrete unit mold. When the frame is slid, it can be lifted integrally with the concrete unit mold while holding the upper and lower horizontal flap members 14 and 15 in the vicinity of the mounting position. The upper and lower horizontal butterfly members 14 and 15 can be tightened. As a result, in the high place work on the temporary scaffold 20 with a high risk, the work of moving the upper and lower horizontal butterfly 14 and 15 which are long objects or returning (reassembling) to the required place is omitted. The cost reduction of construction costs due to the rationalization of safety management, process management, etc. is also great, and a dramatic practical effect is obtained.

Furthermore, the pressing force of the fastening bracket 22 on the support bracket 21 of the concrete unit mold frame is applied to the concrete unit mold frame on which the spread sheet material 13 serving as a base is fixed at the lower end of the concrete unit mold frame. In order to suspend the concrete unit formwork so that the breathable material 23 for transmitting to the concrete unit formwork is disposed on the side surface of the lower end portion of the concrete unit formwork and to hold the butter material 23 A hook-shaped or generally fishhook-shaped hanging metal fitting 25 as shown in FIGS. 14 and 15 for attaching the sling rope 24 to be used is appropriately positioned on the concrete unit mold frame by a fixing member such as a screw or a screw bolt, for example, 2 or more locations relative to the width of the concrete unit formwork, or just enough to support stability Lance is well arranged and fixed. This speeds up the slinging work at the base of the concrete unit formwork.

In addition, at the top of the concrete unit formwork, a guide fitting 26 for guiding the sling rope 24, which is used for sliding movement of the concrete unit formwork, corresponding to the above-described suspension fitting 25, is provided for the concrete unit formwork. Is fixed at a position where it can be suspended in a well-balanced manner. A skid fitting 28 for stably guiding the movement of the concrete unit formwork is fixed to the uppermost portion of the already-cast concrete frame 27 by a fixing member such as a screw bolt.

The above-described skid fitting 28 is for preventing contact with the slab-drawing separator 16 or the plate-like separator 2 which is left on the uppermost stage for fixing the support fitting 21 of the concrete unit form frame and which protrudes from the concrete casing 27. The fixing position is not particularly limited, and may be fixed at two or more points and at an appropriate position.

In the figure, a skeleton 27 indicates a concrete skeleton, and corresponds to, for example, a foundation that has already been placed or a lower floor at the construction stage. The slab pulling separator 16 shown in FIG. 3 used for holding the slab pulling separator 16 or the plate separator 2 set on the top of the plate separator 2 shown in FIG. A support bracket 21 of a concrete unit mold frame that receives the concrete unit mold frame is mounted on the separator 16 for pulling the slab or the plate-like separator 2 protruding from the casing 27.

As shown in FIG. 3, the slab pulling separator 16 has a small hole 29 into which a nail, a screw bolt or the like is inserted at one rear end portion of the plate-like separator 2, and the slab pulling separator 16 is provided.

By pressing and clamping the lower end of the concrete unit formwork, the height direction and the connecting direction, which is the position adjustment between the concrete formwork, which has been conventionally required, can be prevented. The operation to fix the formwork because the surface-passing work follows the existing concrete placement surface Thus it is possible to allowed to maintain smoothness, resulting prevent tongue and groove concrete beating joint surface, thereby to obtain the effect of improving the construction accuracy and construction efficiency.

Further, the hanging metal fitting 25 is fixed at an appropriate position on the lower end portion of the concrete unit mold, and on the other hand, the slinging rope 24 is guided to an appropriate position on the upper end portion of the concrete unit mold corresponding to the hanging metal fitting 25. On the other hand, the stability of the concrete unit formwork is supported at the time of lifting by attaching the skid metal fitting 28 that stably guides the concrete unit formwork to the uppermost part of the concrete placement part. As a result, work safety will be improved.

Regarding the construction or construction procedure of the concrete unit formwork slide method according to the present invention, first, the slab pulling set on the uppermost part of the concrete frame 27 corresponding to the already-founded foundation was used. The fastening bracket 31 is connected to the separator 16 or the plate-like separator 2, and the fastening bracket 31 is used to position the fixed leg portion 32 of the support bracket 21 of the concrete unit mold frame at a predetermined location. The nut 34 that is screwed into the nut 33 is pressed and clamped.

Thereafter, the spread sheet material 13 serving as a base is placed on the support bracket 21 of the concrete unit formwork, and the first concrete formwork 1 is lifted by hand movement or a hoist, a crane, etc. When the concrete mold 1 is carried into the space formed by the side surface and the fastening bracket 22 and the lower joint rod 12 fixed to the front surface of the siding plate 10 of the concrete mold 1 is placed in the previous concrete placement. When the shaft bolt 36 of the tightening bracket 22 provided on the upper part of the support bracket 21 of the concrete unit mold is rotated by being laid on the spreader material 13 so as to engage with the formed joint groove 35, the above-mentioned With the seat plate 37 attached to the tip of the shaft bolt 36 as it advances, the butter material 23 that supports the air permeability is pressed, and the concrete unit mold The end pressing nip. The existing vertical concrete ribs 6 are fixed to each other by an appropriate fixing means (for example, using a nail, a screw bolt, or a clip metal fitting) while being built in with the concrete molds 1a, 2b in order, so that the existing concrete is provided. The concrete formwork 1 is arranged and fixed on one surface with the housing 27 surface as a reference.

Subsequently, in order to prevent the concrete unit formwork from collapsing, a commercially available temporary metal fitting 38 that is generally used is used, or it is reinforced by an appropriate reinforcing means and vertically (built) adjusted, The edge rib 8 under the concrete mold 1 is laid and fixed to the butter material 13 with screws or screw bolts, etc., and then the cone cup 4 attached to the slab-drawing separator 16 or the plate-like separator 2 and the concrete The concrete mold siding plate 10 is sandwiched by a washer 41 fitted to the bearing portion 40 of the connecting member 39 of the mold fastening metal fitting 17, and the slab-drawing separator 16 or the plate-like separator 2 and the concrete using a wedge 42. The frame fastening metal fitting 17 is connected, and then the horizontal butterfly material temporary fitting metal is inserted into the long hole 43 formed in the wedge 42. 4, and then, while placing the upper and lower horizontal members 14 and 15, the seat plate 45 is rotated vertically from the position of the imaginary line (two-dot chain line) shown in FIG. By rotating and pressing and fixing the nut 47 to be tightened, the nut 47 becomes strong and supports the lateral pressure due to the concrete load. However, the use of the horizontal butterfly material provisional metal fitting 44 is not necessarily essential and may be used according to necessity.

Then, the concrete form 48 on the inner wall side of the concrete case 27a that forms a pair with the concrete unit form frame is arranged at the position of the imaginary line (two-dot chain line) shown in FIG. 19 through the reinforcement as the strength member of the concrete case 27. This will prepare for concrete placement. As a result, the casting surface of the concrete unit formwork forms a continuous surface with the existing concrete frame 27 surface, and it is possible to place it with high accuracy as a smooth continuous surface without causing any confusion in placing.
