  An example of the procedure for installing the separator is as follows. A plurality of anchor holes are drilled in the wall of the building, and a plurality of through holes are drilled in the veneer plate of the mold corresponding to the position of the anchor hole. Next, resin anchors and mechanical anchors are installed in the anchor holes, and one clamp metal fitting of the separator is connected to the resin anchors or mechanical anchors, and the other clamp metal fitting exposed from the through hole of the plywood plate is cylindrical. Screw the clamp with the tube engaged. When assembling the formwork, not only do you have to install a considerable number of separators per unit area of the wall, taking into account the position of the reinforcing bars so that they do not collide with the reinforcing bars, but also anchor holes in the building walls When a hole is drilled, it is necessary to avoid the reinforcing bars embedded in the wall. Further, after determining the drilling position for drilling the anchor hole, a plurality of positions corresponding to the anchor hole at any position of the plywood plate corresponding to the drilling position The through hole must be drilled. Accurate positioning (marking out) the drilling position of the anchor hole with respect to the wall and the through hole with respect to the plywood, and ensuring that the parallel state of the wall and the plywood is maintained does not rely on many years of experience in formwork It is the present condition that we do not get.

  As another example of the present invention, the formwork panel is divided into a plurality of sheets in the vertical direction, and these panels are removably inserted between the first and second horizontal members and the vertical material, and are vertically Are supported by the horizontal members and the longitudinal members.

  As another example of the present invention, at least one of the formwork panels is provided with a supply port for placing concrete in a space between the wall surface and the panel, and at least one of the formwork panels is provided with When concrete is placed in the space between the wall surface and the panel, a confirmation window is formed that can confirm the concrete placement state in the space.

  As another example of the present invention, a synthetic resin is applied to the outer peripheral surfaces of the form panels so as to reduce the frictional resistance against the concrete on the opposing surface facing the wall of the panel and increase the strength of the entire panel.

  As another example of the present invention, in the formwork, the number of the first horizontal installation material installed on the formwork panel positioned in the lower vertical direction is higher than that of the first horizontal installation material on the mold panel positioned in the upper vertical direction.

  As another example of the present invention, in the formwork, the longitudinal members are arranged at substantially equal intervals in the horizontal direction, and the vertical members are arranged at substantially equal intervals in the horizontal direction.

  As another example of the present invention, the building is an existing one, and the formwork is used to construct a seismic reinforcing wall made of reinforced concrete made on the wall surface of the existing building.

  According to the mold according to the present invention, a plurality of first horizontal installations that are positioned in front of the mold panel in the front-rear direction, are supported by the longitudinal members, extend in the horizontal direction, and are arranged at a predetermined distance in the vertical direction. Since the first horizontal installation material suppresses the bulging forward of the formwork panels in the front-rear direction due to the side pressure of the concrete when the concrete is placed in the space between the wall surface and the panel, the concrete in the space It is possible to prevent the panel from being deformed forward in the front-rear direction when the is placed. Furthermore, it has a plurality of vertical installation materials that are in contact with the first horizontal installation material and extend in the vertical direction and are spaced apart by a predetermined dimension in the horizontal direction, and concrete is placed in the space between the wall surface and the panel. When the concrete is placed in space, the panels and the first horizontal members are moved forward in the front-rear direction because the vertical members press the bulges of the first horizontal members forward in the longitudinal direction due to the lateral pressure of the concrete. Can prevent deformation. The formwork can sufficiently withstand the lateral pressure of the concrete placed in the space between the wall surface and the panel by using the first horizontal construction material and the vertical construction material. Since the parallel state of the panel and the panel can be maintained, it is possible to reliably add concrete to the wall surface, and to create a new wall as designed by the structural calculation outside the existing wall. The formwork does not need to install multiple separators when assembling it, and not only can save labor and time to install the separator, it also does not need to rely on the experience of formwork carpenters, but in a short time In addition to being able to assemble efficiently, it can be assembled inexpensively without the need for labor.

  A formwork including a plurality of second horizontal installation members which are fixed to the vertical installation material while being positioned in front of the vertical installation material in the front-rear direction and extending in the horizontal direction and spaced apart by a predetermined dimension in the vertical direction includes a wall surface and a panel. When the concrete is placed in the space, the second horizontal members suppress the bulging of the vertical members in the front-rear direction due to the side pressure of the concrete when the concrete is placed in the space between them. It is possible to prevent deformation of the material in the front-rear direction and bending in the lateral direction. The formwork can sufficiently withstand the lateral pressure of concrete placed in the space between the wall and the panel by using these first horizontal members, these vertical members, and these second horizontal columns. Because it is possible to maintain the parallel state of the wall and panel of the building, concrete can be added to the wall of the building without fail, and the structure calculated on the outside of the existing wall is as designed. New walls can be created.

  A formwork in which a support plate that protrudes laterally from the rear wall of the longitudinal member and prevents the formwork panel placed between the longitudinal members from falling into the wall surface side is installed on the longitudinal member. The frame panel is supported by a support plate installed on the longitudinal member, the panel does not fall toward the wall surface, and the parallel state of the wall surface of the building and the panel can be maintained. Because concrete can stay in the space between the concrete and concrete, it is possible to reliably add concrete to the wall of the building, and to create a new wall as designed by the structural calculation outside the existing wall Can do.

  The formwork provided with a plurality of support fittings that are installed on the front plate and are spaced apart from each other by a predetermined dimension in the vertical direction and that support the first horizontal installation material is first supported by the support fittings. Since the abutting state of the horizontally mounted material against the outer surface of the panel is maintained, it is possible to prevent the panel from deforming forward in the front-rear direction due to the side pressure of the concrete when the concrete is placed in the space between the wall surface and the panel. . The formwork uses the first horizontal members, the vertical members, and the second horizontal members that are supported by the support bracket, so that the lateral pressure of the concrete placed in the space between the wall surface and the panel is used. Therefore, it is possible to reliably add concrete to the wall surface of the building, and to create a new wall as designed by the structural calculation outside the existing wall.

  The first and second horizontal members have a fixed plate and first and second side plates, and the longitudinal members can be inserted and removed between the fixed plate of the first horizontal member and the first and second side plates. Between the upper end supported by the first horizontal member, the fixing plate of the second horizontal member, and the first and second side plates so as to be detachable and supported by the second horizontal member. The upper and lower ends of the longitudinal members lined up with a predetermined distance in the horizontal direction are between the first and second side plates and the fixed plate of the first and second horizontal members. The formwork panel can be firmly arranged between the first and second horizontal members and the longitudinal member by being inserted and supported by the horizontal members. The formwork can maintain the parallel state between the wall of the building and the panel, and the concrete can be retained in the space between the wall by the panel. It is possible to make a new wall as designed by the structural calculation outside the existing wall.

  A truss structure in which a vertically erected material is made up of first and second vertical members that extend straight in the vertical direction and a truss member that is positioned between the vertical members and extends in a zigzag direction in the vertical direction. The formwork in which the upper end of the truss structure is fixed to the bottom surface of the slab or beam of the building through fixing means and the lower end of the truss structure is fixed to the floor of the building through fixing means is a wall and a panel. When the concrete is placed in the space, the truss members of these truss structures hold the bulges of the first horizontal laying members forward and backward due to the side pressure of the concrete when the concrete is placed in the space between them. It is possible to prevent the panels and the first horizontal members from being deformed forward in the front-rear direction. Since the formwork can sufficiently withstand the lateral pressure of the concrete placed in the space between the wall surface and the panel by using these first horizontal members and these truss structures, Concrete can be added to the wall without fail, and a new wall can be created outside the existing wall as designed by the structural calculation.

  The truss structure includes a dimension adjuster capable of adjusting its height dimension, the dimension adjuster positioned on the side of the building and fixed on the building and positioned on the side of the first vertical member. A mold frame having an opening capable of adjusting a fixed position in a vertical direction with respect to the first vertical member, the first vertical member being detachably connected to the dimension adjusting material via the opening, is formed by the dimension adjusting material. Since the vertical dimension of the structure can be adjusted, the vertical dimension of the truss structure can be matched with the height dimension of the wall surface of the building, and the truss structure is securely fixed to the building be able to. Since the truss structures hold down the bulges forward of the formwork panels and their first horizontal members in the front-rear direction due to the side pressure of the concrete, when the concrete is placed in the space between the wall and the panel It is possible to prevent the panels and the first horizontal members from being deformed forward in the front-rear direction. Since the formwork can sufficiently withstand the lateral pressure of the concrete placed in the space between the wall surface and the panel by using these first horizontal members and these truss structures, Concrete can be added to the wall without fail, and a new wall can be created outside the existing wall as designed by the structural calculation.

  The formwork panel is divided into a plurality of sheets in the vertical direction, and the panels are detachably fitted between the first and second horizontal members and the vertical member, and are arranged in the vertical direction. The formwork supported by the longitudinal member is formed by dividing the formwork panel divided into a plurality of pieces in the vertical direction into the first and second horizontal members even when the height of the wall surface of the building is large. A panel can be installed in the whole height dimension of a wall surface by arranging in the up-down direction between longitudinal members. The formwork can maintain the parallel state between the wall of the building and the panel, and the concrete can be retained in the space between the wall by the panel. It is possible to make a new wall as designed by the structural calculation outside the existing wall.

  The supply port for placing concrete in the space between the wall surface and the panel is made in at least one of the formwork panels, and when placing concrete in the space between the wall surface and the panel, the concrete into the space Forms in which at least one of the formwork panels has a confirmation window capable of confirming the placement state of the concrete can be easily placed in the space by using a supply port made in the panel. The concrete can be easily applied to the wall of the building. Since the formwork can confirm the concrete placement condition in the space from the confirmation window, concrete can be reliably placed over the entire space, and concrete must be added to the wall of the building. Can do.

  Formwork with synthetic resin applied to these panels, which reduces the frictional resistance against concrete and increases the strength of the entire formwork panel, smoothes the facing surface facing the panel wall surface by applying synthetic resin. Since the frictional resistance against the concrete on the opposing surface is reduced, the panel can be easily removed from the hardened concrete when the formwork is removed after curing the placed concrete. Since the smoothness of the opposing surface of a formwork panel is maintained by a synthetic resin, a used panel can be used repeatedly and the cost concerning a formwork can be held down. In the formwork, the strength of the panel is increased by the synthetic resin, and the panel is prevented from buckling and breakage during use, so the panel can retain the concrete in the space between the wall and the building. It is possible to reliably add concrete to the wall surface.

  The number of installations of the first horizontal installation material with respect to the formwork panel positioned below in the vertical direction is larger than that of the first horizontal installation material with respect to the formwork panel positioned above in the vertical direction. The side pressure of the concrete placed in the space acts greatly on the panel located below, but since there are many installations of the first horizontal installation material for the formwork panel positioned below in the vertical direction, the first horizontal installation material The bulging forward of the panels in the front-rear direction is reliably suppressed, and deformation of the panels in the front-rear direction when the concrete is placed in the space between the wall surface and the panel can be reliably prevented.

  The first horizontal installation material is arranged at the center in the vertical direction of the formwork panel, and the formwork in which these first horizontal installation materials are arranged at both ends in the vertical direction of the formwork panel is the first horizontal installation Since the vertical center part of the panel is pressed by the material and both vertical ends of the panel are pressed, the bulging forward of the panel in the front-rear direction is surely pressed by the first horizontal installation material, and the wall and the panel It is possible to reliably prevent the panel from deforming forward in the front-rear direction due to the side pressure of the concrete when the concrete is placed in the space between them. Even when a plurality of formwork panels are lined up and down, the formwork is pushed by the first horizontal members at the upper and lower ends of each panel. It is prevented by the first horizontal laying material, and leakage of concrete from the abutting portions of these panels can be prevented.

  The formwork in which the longitudinal members are arranged in the horizontal direction at substantially equal intervals, and the vertical frame members are arranged in the horizontal direction at substantially equal intervals, the vertical members are separated in the horizontal direction at substantially equal intervals. The horizontal dimension of the formwork panel can be made the same, and the variation in the strength of each panel due to the different horizontal dimension of the panel can be prevented. It is possible to prevent partial deformation of the panel when concrete is placed in the space. Since the formwork is installed with the vertical installation materials spaced apart at substantially equal intervals in the horizontal direction, the panels and the first horizontal installation material can be uniformly pressed by the vertical installation materials. When the concrete is placed in the space between the panels, it is possible to reliably prevent the panels and the first horizontal members from being deformed forward in the front-rear direction.

  The formwork used to construct the reinforced concrete seismic reinforcement walls made on the wall of the existing building is the existing one, and the structure was calculated on the wall of the existing building using the formwork It is possible to install a new reinforced concrete seismic reinforcement wall as designed. The formwork can efficiently make a reinforced concrete seismic reinforcing wall in a short time, and can make the seismic reinforcing wall inexpensively without requiring labor.

  The details of the mold according to the present invention will be described below with reference to the accompanying drawings such as FIG. 1 which is a front view showing an example of the assembled mold 10A. 2 is a side view of the assembled mold 10A, and FIG. 3 is a partially enlarged perspective view of the first horizontal member 17 and the vertical stud 19 shown as an example. FIG. 4 is a partially enlarged perspective view of the second horizontal member 18 and the vertical stud 19 shown as an example.

  1 and 2, the vertical direction is indicated by arrow A, the horizontal arrow B (only in FIG. 1), and the front-back direction is indicated by arrow C (only in FIG. 2). In FIG. 2, illustration of reinforcing bars embedded in the concrete 13 is omitted. In FIG. 3, a state in which the upper end portion of the vertical stud 19 is fitted into the first horizontal member 17 is indicated by a two-dot chain line, and in FIG. 4, a state in which the lower end portion of the vertical stud 19 is fitted into the second horizontal member 18 is illustrated. Indicated by a two-dot chain line.

  The formwork 10A is assembled at a position spaced apart by a predetermined dimension forward and backward in the front-rear direction of the wall surface 12 of the existing building 11 (building). Used to make 78. A plurality of reinforcing bars (not shown) are arranged at the location where the seismic reinforcement wall 78 is formed, and the mold 10A is assembled, and the space 14 between the wall 12 and the mold 10A (the mold panel 20) (the wall 12). Concrete 13 is placed on the outside. After the cast concrete 13 is cured for a predetermined period, the assembled formwork 10A is removed (disassembled), whereby a reinforced concrete seismic reinforcement wall 78 is made.

  1 and 2, the case where the earthquake-proof reinforcement wall 78 is constructed on the wall surface 12 of the existing wall 16 provided between the pillars 15 of the building 11 is illustrated, By using the mold 10A (including the mold 10B described later), the seismic reinforcement wall 78 can be constructed on the wall surface of any existing wall such as a wall between wall beams and a wall between floor slabs. . The existing walls include all walls such as outer walls, load-bearing walls, partition walls, hanging walls, sleeve walls, and waist walls. The mold 10A includes a first horizontal member 17 (first runner) and a second horizontal member 18 (second runner), a plurality of vertical pillars 19 (vertical members) (studs), and a plurality of molds. The frame panel 20, a plurality of first horizontal columns 21 (first horizontal members), a plurality of truss structures 22 (vertical members), and a plurality of second horizontal columns 23 (second horizontal columns) Construction material).

  The 1st horizontal member 17 (1st runner) is installed in the position spaced apart from the wall surface 12 in the front-back direction, and extended in the horizontal direction. The first horizontal member 17 is made of a metal such as iron, aluminum, brass, or an alloy, and is attached to or detached from the first horizontal member attachment point (the ink marking point) on the slab bottom surface 24 or the beam bottom surface 24 of the building 11. Installed as possible. The location where the first horizontal member 17 is attached to the slab bottom surface 24 and the beam bottom surface 24 (the distance from the wall surface 12 to the front in the front-rear direction) differs depending on the thickness dimension determined by the structural calculation of the newly installed seismic reinforcing wall 78. As shown in FIG. 3, the first horizontal member 17 is formed of a fixed plate 25 and first and second side plates 26 and 27.

  The fixed plate 25 is arranged at a position where the slab bottom surface 24 or the beam bottom surface 24 of the building 11 is positioned and extends straight in the lateral direction. A plurality of fastening holes 28 are formed in the fixing plate 25 at predetermined intervals, and a joining member 29 such as a nail, a bolt, or a screw is driven into the fastening holes 28 and the slab bottom surface 24 or the beam bottom surface 24 of the building 11. Thus, the fixing plate 25 (first horizontal member 17) is firmly fixed to the slab bottom surface 24 and the beam bottom surface 24. The first side plate 26 faces the wall surface 12 and extends downward from one side edge of the fixed plate 25 in the vertical direction, and extends in a straight shape in the lateral direction. The second side plate 27 is located on the opposite side of the first side plate 26 and extends downward in the vertical direction from the other side edge of the fixed plate 25 and extends straight in the lateral direction. The second side plate 27 is formed with a tightening hole 30 penetrating therethrough. The second side plate 27 has a dimension that extends downward in the vertical direction shorter than that of the first side plate 26 that extends downward in the vertical direction.

  The second horizontal member 18 (second runner) is installed at a position spaced apart from the wall surface 12 in the front-rear direction and extends in the horizontal direction. The second horizontal member 18 is made of a metal such as iron, aluminum, brass, or alloy, and is detachably attached to the second horizontal member attachment point (inking point) on the floor surface 31 of the building 11. . The mounting location of the second horizontal member 18 with respect to the floor surface 31 (the distance from the wall surface 12 to the front in the front-rear direction) was determined by the structural calculation of the newly installed seismic reinforcing wall 78 in the same manner as the first horizontal member 17. It depends on the thickness dimension. In addition, the 1st horizontal member attachment location of the slab bottom surface 24 or the beam bottom surface 24 and the 2nd horizontal material attachment location of the floor surface 31 correspond substantially correctly, and the 2nd horizontal material 18 is the 1st horizontal material. It is arranged and fixed in parallel to the material 17. As shown in FIG. 4, the second horizontal member 18 is formed of a fixed plate 32 and first and second side plates 33 and 34.

  The fixed plate 32 is arranged at a position where the floor surface 31 of the building 11 is positioned and extends straight in the lateral direction. A plurality of tightening holes 35 are formed in the fixing plate 32 at predetermined intervals. The fixing plate 32 is fixed by driving a joining member 36 such as a nail, a bolt, or a screw into the tightening holes 35 and the floor surface 31 of the building 11. The plate 32 (second horizontal member 18) is fixed to the floor 31. The first side plate 33 is opposed to the wall surface 12 and extends upward in the vertical direction from one side edge of the fixed plate 32 and extends linearly in the lateral direction. The second side plate 34 is located on the opposite side of the first side plate 33 and extends upward in the vertical direction from the other side edge of the fixed plate 32 and extends straight in the horizontal direction. The second side plate 34 is formed with a tightening hole 37 penetrating therethrough. The first side plate 33 and the second side plate 34 have the same vertical dimension extending downward.

  The vertical pillars 19 (longitudinal members) (studs) are arranged between the first horizontal member 17 and the second horizontal member 18 and extend in the vertical direction. The vertical pillars 19 are arranged between the first horizontal member 17 and the second horizontal member 18 at substantially equal intervals in the horizontal direction. In FIG. 1, the three vertical columns 19 are illustrated, but the number of the vertical columns 19 is not particularly limited, and is calculated by a structural calculation that takes into account the horizontal dimensions and thickness dimensions of the seismic reinforcing wall 78 to be constructed. The number of vertical studs 19 to be used is determined. Moreover, it is not necessary that the vertical pillars 19 are arranged in the horizontal direction at substantially equal intervals, and the vertical pillars 19 may be arranged in different dimensions in the horizontal direction.

  As shown in FIGS. 3 and 4, the vertical spacers 19 are hollow metal tubes having a square cross-sectional shape made of a metal such as iron, aluminum, brass, and an alloy. Other shapes such as metal tubes and metal columns, H-shaped steel, I-shaped steel, and square steel materials can also be used. The vertical pillar 19 includes a front plate 38 and a rear plate 39, and both side plates 40 and 41 extending between the front and rear plates 38 and 39, and an upper end portion 41 supported by the first horizontal member 17 and a second plate. A lower end 43 supported by the horizontal member 18. The front plate 38 faces the first horizontal installation column 21, and the rear plate 39 faces the wall surface 12 of the building 11. The front plate 38 at the upper end portion 42 is formed with a fastening hole 44 penetrating therethrough. The front plate 38 at the lower end 43 is formed with a fastening hole 45 penetrating therethrough. The rear plate 39 is provided with a pair of support plates 46 extending in the lateral direction. The support plate 46 prevents the formwork panel 20 disposed between the vertical pillars 39 from falling to the wall surface 12 side.

  In addition, although the rear plate 39 and the support plate 46 are integrated in the longitudinal pillars 19, a separate support plate may be detachably installed on the rear plate 39. In this case, an L-shaped angle is prepared as a support plate, and a fixing plate of one angle is fixed to one side plate 40 of the vertical stud 19 (fixed by an adjuster bolt or welding), and a fixing plate of the other angle is fixed. The vertical plate 19 is fixed to the other side plate 41 (fixed by an adjuster bolt or welding), and the angle free plate is extended from the rear plate 39 in the lateral direction, so that the angle free plate is used as the support plate 46. .

  As shown by a two-dot chain line in FIG. 3, the longitudinal pillars 19 are configured such that the front and rear plates 38 and 39 and the side plates 40 and 41 of the upper end portion 42 are the first and second fixing plates 25 of the first horizontal member 17.

In addition, the separation dimension from the wall surface 12 of the mounting portion of the truss structure 22 on the surface 24 to the front in the front-rear direction and the separation dimension of the mounting portion of the truss structure 22 on the surface 31 from the wall surface 12 to the front in the front-rear direction are the same.

  Anchor holes (not shown) aligned in the lateral direction are drilled in the truss mounting positions where the slab bottom surface 24 or the beam bottom surface 24 is positioned, and resin anchors or mechanical anchors are installed in these anchor holes. Next, the angle 72 is arranged on the third line so that the upper end portion 70 of the truss structure 22 is accurately positioned on the third line, and the anchor bolt 73 is inserted into the bolt hole formed in the angle 72. The anchor bolt 73 is screwed into the anchor hole, and the angle 72 is firmly fixed to the truss attachment location on the slab bottom surface 24 or the beam bottom surface 24.

  In addition, anchor holes (not shown) arranged in the lateral direction are drilled in the truss mounting positions positioned on the floor surface 31, and resin anchors or mechanical anchors are installed in these anchor holes. Next, the angle 72 is arranged on the fourth line so that the lower end 71 of the truss structure 22 is accurately positioned on the fourth line, and the anchor bolt 73 is inserted into the bolt hole formed in the angle 72. The anchor bolt 73 is screwed into the anchor hole to firmly fix the angle 72 to the truss mounting location on the floor 31.

  Next, an adjuster bolt 74 is screwed into a bolt screw hole (not shown) drilled in the angle 72 and a bolt screw hole (not shown) drilled in the lower end portion of the first vertical member 66, A nut is screwed onto the bolt 74 to firmly fix the lower end portion of the first vertical member 66 to the angle 72. In order to adjust the vertical dimension of the truss structure 22, the fixing position of the upper end portion of the first vertical member 66 with respect to the opening 76 of the dimension adjusting member 69 is determined. After the fixing position is determined, the upper end portion of the first vertical member 66 is firmly fixed to the opening 76 of the dimension adjusting member 69 at the fixing position. The upper end portion of the first vertical member 66 and the dimension adjusting member 69 are fixed via fixing bolts and nuts. Further, an adjuster bolt 74 is screwed into a bolt screw hole (not shown) drilled in the angle 72 and a bolt screw hole (not shown) drilled in the fixed end portion 75 of the dimension adjusting member 69. A nut is screwed onto the bolt 74 to firmly fix the fixed end 75 of the dimension adjusting member 69 to the angle 72.

  If the lower end portion of the first vertical member 66 and the fixed end portion 75 of the dimension adjusting member 69 are fixed to the angle 72 while adjusting the vertical dimension of the truss structure 22, the first vertical member of the truss structure 22 is fixed. 75 abuts on each first horizontal pillar 21. The truss structure 22 prevents the form panel 20 and the first horizontal column 21 from being deformed forward in the front-rear direction and prevents the stacked panels 20a to 20c from collapsing.

  After these truss structures 22 are installed in front of the first horizontal columns 21, a second horizontal column installation process is performed. In the second horizontal installation column installation step (second horizontal installation material fixing step), as shown in FIG. 17, a plurality of second horizontal installation columns 23 (second horizontal installation materials) extending in the horizontal direction are predetermined in the vertical direction. The truss structure 22 is installed in front of the truss structure 22 in the front-rear direction in a state where the dimensions are separated. In the second horizontal installation pillar installation step, the second horizontal installation pillar 23 is firmly fixed to the second vertical member 67 of the truss structure 22 via the fixing bracket 77. These second horizontal columns 23 prevent the truss structure 22 from being deformed forward and backward and bent laterally.

  When the positioning process, horizontal member installation process, vertical column installation process, panel installation process, first horizontal installation column installation process, truss structure installation process, and second horizontal installation column installation process are completed, the form 10A shown in FIG. Is completed. A space 14 in which the concrete 13 is placed is formed between the wall surface 12 and the formwork 10A (formwork panels 20a to 20c). Although not shown in the drawing, an air hole for releasing air existing in the space 14 when the concrete 13 is placed in the space 14 to the outside is formed in any of the form panels 20a. After assembling the mold 10A, a concrete placing process is performed. In the concrete placing step, as shown in FIG. 17, the concrete 13 is placed in the space 14 from the supply port 64 formed in the mold panel 20a. Although the concrete 13 is placed in the space 14 (not shown), a hose extending from the concrete mixer is connected to the supply port 64 of the panel 20a, and the concrete 13 is press-fitted into the space 14 from the supply port 64. The air in the space 14 is exhausted to the outside through the air hole of the formwork panel 16a. In the concrete placing process, the concrete 13 is placed while visually confirming the space 14 from the confirmation window 65 and using the confirmation window 65 to determine the placement state of the concrete 13 into the space 14.

  In the concrete placing process, by using the supply port 64 made in the formwork panel 20a, the concrete 13 can be easily placed in the space 14, and the concrete 13 can be easily added to the wall surface 12 of the building 11. You can hit. In addition, since the concrete 13 can be placed in the space 14 through the confirmation window 65, the concrete 13 can be reliably placed in the entire space 14, and the concrete 13 can be reliably added to the wall surface 12. can do.

  When the concrete 13 is placed in the space by the concrete placing step, the lateral pressure of the concrete 13 that has entered the space 14 acts on the formwork panels 20a to 20c. When the side pressure of the concrete 13 acts on the panels 20a to 20c, the panels 20a to 20c try to bulge forward in the front-rear direction, but the bulges of the panels 20a to 20c are suppressed by the first horizontal pillars 21, and the concrete The deformation of the panels 20a to 20c and the collapse of the stacked panels 20a to 20c due to the 13 side pressure are prevented. Moreover, although the 1st horizontal installation pillar 21 tries to bulge ahead in the front-back direction by the side pressure of the concrete 13, the deformation | transformation of each 1st horizontal installation pillar 21 is prevented by these truss structures 22. FIG. Further, the truss structure 22 tends to bulge forward in the front-rear direction due to the lateral pressure of the concrete 13, but the bulge of each truss structure 22 is suppressed by the second laterally extending columns 23, and the truss structure due to the lateral pressure of the concrete 13. 22 is prevented from being deformed or bent.

  In the mold frame 10A, the first horizontal pillars 21 and the second horizontal pillars 23 serve as lateral presses with respect to the mold panels 20a to 20c, and the truss structures 22 extend in the vertical direction with respect to the panels 20a to 20c. Even if the lateral pressure of the concrete 13 placed in the space 14 acts on the panels 20a to 20c, the panels 20a to 20c are not bent, and the straight state of the panels 20a to 20c can be maintained. it can. Furthermore, since the polyurea resin 63 is applied to the six surfaces 58 to 62 of the panels 20a to 20c, and the bending strength of the panel 20 itself is greatly increased by the cured polyurea resin 63, the lateral pressure of the concrete 13 is increased to each panel 20a. Even if it acts on .about.20c, the panels 20a.about.20c are not bent, and the straight state of the panels 20a.about.20c can be maintained.

  After placing the concrete 13 in the space 14, the concrete 13 is cured for a predetermined period. After the curing period of the concrete 13 elapses, a mold removal process is performed. In the mold removal process, the fixing metal 77 is removed from the second vertical member 67 of the truss structure 22, and the second horizontal pillars 23 are removed from the truss structure 22. After removing the second horizontal pillar 23, the adjuster bolt 74 is removed from the bolt screw hole of the angle 72 and the bolt screw hole of the fixed end portion 75 of the dimension adjusting member 69, and the fixed end portion 75 of the dimension adjuster 69 and The fixing to the angle 72 is released, and the adjuster bolt 74 is removed from the bolt screw hole of the angle 72 and the bolt screw hole of the lower end portion of the first vertical member 66, and the lower end portion of the first vertical member 66 and the angle 72 are The truss structure 22 is removed from the first horizontal column 21.

  After removing the truss structure 22, the anchor bolt 73 is removed from the resin anchor or mechanical anchor in the anchor hole drilled in the truss mounting location of the floor surface 31, and the fixing between the floor surface 31 and the angle 72 is released. The anchor bolt 73 is extracted from the resin anchor or the mechanical anchor in the anchor hole drilled in the truss mounting position on the slab bottom surface 24 or the beam bottom surface 24, and the slab bottom surface 24 or the beam bottom surface 24 and the angle 72 are fixed.

  After removing the angle 72, the first horizontal columns 21 are extracted from between the mounting portion 52 and the pressing portion 53 of the support seat 49, and all the first horizontal columns 21 are removed from the vertical column 19. After removing the first horizontal column 21, the formwork panels 20 a to 20 c are removed from between the vertical columns 19. Since the polyurea resin 63 is applied to the 6 surfaces 58 to 62 of the panels 20a to 20c, and the frictional resistance of the 6 surfaces 58 to 62 is greatly reduced, the cured concrete 13 after curing is the panels 20a to 20c. The panels 20 a to 20 c can be easily removed from the concrete 13 without adhering to the facing surface 57. Moreover, since the extension dimension to the downward direction of the 2nd side plate 27 of the 1st runner 17 is shorter than that of the 1st side plate 26, the panel 20a does not bite into the 1st runner 17, and is fixed to the runner 17, The panels 20a to 20c can be easily removed from the first and second runners 17 and 18.

  After removing the formwork panels 20a to 20c, the joining member 47 is extracted from the binding hole 30 of the first horizontal member 17 and the binding hole 44 of the vertical spacer 19, and the binding hole 37 and the vertical pillar of the second horizontal member 18 are extracted. The bonding member 47 is removed from the 19 tight holes 45 to release the fixing of the first and second horizontal members 17 and 18 and the vertical spacer 19. Next, the vertical spacers 19 are removed from the first and second horizontal members 17 and 18. After removing the vertical pillar 19 from the first and second horizontal members 17, 18, the first horizontal member 17 is removed from the slab bottom surface 24 and the beam bottom surface 24, and the second horizontal member 18 is removed from the floor surface 31. . The joining member 29 is extracted from the binding hole 28 of the first horizontal member 17, the slab bottom surface 24 and the beam bottom surface 24 to release the slab bottom surface 24 and beam bottom 24 from the first horizontal member 17. The joining member 36 is extracted from the binding hole 35 and the floor surface 31 of the second horizontal member 18 to release the fixation between the floor surface 31 and the second horizontal member 18. By removing all the members that form the mold 10A and removing (disassembling) the assembled mold 10A, a newly installed seismic reinforcement wall 78 made of reinforced concrete is produced.

  The formwork 10A uses the first horizontal installation pillar 21 (first horizontal installation material), the truss structure 22 (vertical installation material), and the second horizontal installation pillar 23 (second horizontal installation material). 11 can sufficiently withstand the lateral pressure of the concrete 14 placed in the space 14 between the wall surface 12 and the formwork panel 20, and the parallel state between the wall surface 12 and the panel 20 can be maintained. The concrete 13 can be reliably added to the outer wall 12, and a new seismic reinforcing wall 78 made of reinforced concrete can be made outside the existing wall 16 as designed by the structural calculation.

  The mold 10A does not need to install a plurality of separators when assembling it, and can save labor and time for installing separators, and does not need to rely on the experience of a mold carpenter. In addition to being able to assemble efficiently, it can be assembled inexpensively without the need for labor. Moreover, since it is not necessary to install a separator in the space 14 in the mold 10A, the reinforcing bars arranged in the space 14 do not interfere with the installation of the separator, and the reinforcing bars are arranged freely in the space 14. The seismic reinforcement wall 78 made of strong reinforced concrete can be made.
