Description

  The present invention relates to a concrete formwork method including installation of an interior / exterior base member and a formwork panel and an interior / exterior base member used for concrete formwork in construction work, and more particularly, to a method used for a corner.

In the conventional method using concrete formwork, after placing the concrete frame and removing the formwork, lay the base material with a wooden frame on the concrete placement surface, and nail the interior and exterior materials on this. The inner and outer materials are fixed with a light steel frame, and the inner and outer materials are fixed with tapping screws, or the adhesive is applied in a dumpling form and the inner and outer materials are directly pressed.
In addition, when heat insulation is applied, concrete is placed in a state where a heat insulation board made of synthetic resin foam or the like is nailed in advance on the inner surface of the mold plate, and only the plywood is removed after the concrete is hardened. A concrete wall is formed, and after that, a base material for the interior and exterior materials is also assembled and the interior and exterior materials are attached.
As described above, in concrete formwork, it is necessary to fix the interior and exterior members after placing concrete. However, in recent years, as the most rational method, the slats constituting the formwork are used as the foundation of the interior and exterior. There is a construction method. In this method, a foamed plastic insulation board, which is a laminate of foamed plastic insulation, wood wool board, and new building material board, is used as a slab for concrete formwork that can also be used as a base material for interior and exterior materials. The inner and outer materials are finished on the surface without removing the weir plate. In this construction method, a heat insulating material is used for the dam plate, so that the heat insulating work can be performed at the same time.

However, this construction method requires the rigidity and strength sufficient for deformation and breakage of the slats in the formwork. However, the foamed plastic insulation that forms the slats is weak because the panel itself is weak. In other words, it has to be bonded and integrated with another composite plate, which increases the economic burden. In addition, there are many problems related to storage of parts, labor costs, transportation costs, materials, etc. during formwork during construction. These problems are caused by the use of strong slats as the foundation of the interior and exterior, but from the viewpoint of rational work processes, the interior and exterior foundations are formed on the concrete frame when placing concrete. It is desirable to maintain the advantage of
In view of such problems, the inventor of the present application provided a groove having a rectangular cross section in the sill plate of the formwork panel in Patent Documents 1 and 2 below, and fitted an interior / exterior base member that fits into the groove. Is proposed as a formwork for both interior and exterior substrates. This interior / exterior foundation combined form is designed to remove the formwork panel leaving only the interior / exterior foundation member after placing the concrete frame, and the strength of the slats can be maintained by the vertical grooves and the interior / exterior foundation member, The base of the interior and exterior can be formed on the concrete frame at the time of casting.

(Embodiment 1)
FIGS. 1A and 1B are partially enlarged perspective views of the interior / exterior foundation / member frame 20 constituting the interior / exterior foundation / formwork panel X according to Embodiment 1 as seen from different directions. The interior / exterior base member 20 is a long member formed of a synthetic resin, and is formed in an L shape having a hollow cross-sectional shape. In other words, this cross-sectional shape is formed into a hexagonal shape with one angle of 270 degrees and the remaining angle of 90 degrees. The two surfaces sandwiching the corner of 270 degrees form the front surface 21 for attaching the interior and exterior, the two surfaces parallel to the front surface form the back surface 22, and the surfaces connected to both edges of the front surface 21 and the back surface 22 are side surfaces. 23 is formed. The interior / exterior base member 20 is used for a corner formed at 90 degrees, and when the rear surface 22 is aligned with the corner, the front surface is parallel to the two concrete wall surfaces adjacent to the corner. . In addition, if the angle of the corner is changed, the cross-sectional shape of the inner / outer base member 20 may be changed as appropriate, and in this case, as a rule, the front surface is formed to be parallel to the concrete wall surface. Screw holes 21 a are provided at equal intervals in the longitudinal direction on the front surfaces 21 of the inner / outer base member 20.

Furthermore, on the back surface 22 side, strip-like anchor portions 22b that protrude in the back surface direction so as to be orthogonal to the back surface 22 are provided at equal intervals in the longitudinal direction.

  FIG. 2 shows a partially enlarged perspective view of the formwork panel 10 constituting the interior / exterior base / formwork panel X. FIG. The formwork panel 10 is composed of a synthetic resin-made bending plate 11 bent at a right angle. Outer frames 13, which stand up at right angles, are integrally formed on both end surfaces of the dam plate 11. Since this formwork panel 10 is for the corner, the surface adjacent to the outer corner becomes the placement surface. Further, a vertical groove 12 in which the front surface 21 and the side surface 23 of the inner / outer base member 20 can be fitted is formed on the side of the corner portion where the baffle plate 11 is bent. A screw fixing through hole 12a through which a screw passes is formed on a surface of the bottom surface of the vertical groove facing the screw hole 21a when the inner / outer base member 20 is fitted, and a foam tie through hole 21b. A second foam tie through-hole 12b, which is a hole through which the base end portion of the foam tie passes, is formed on the surface opposite to the surface.

Next, the formwork method of a concrete structure using the interior / exterior base combined formwork panel X including the formwork panel 10 and the interior / exterior base member 20 having the above-described configuration will be described. First, the inner / outer base member 20 is fitted into the vertical groove of the mold panel 10 and is engaged with the screw hole 21a of the inner / outer base member 20 through a bolt or the like from the screwing through hole 12a of the mold panel 10 to form the mold. The frame panel 10 and the interior / exterior base member 20 are fixed integrally to form the interior / exterior base / form frame panel X. This operation is usually performed at a factory or the like, not at the site, and is carried into the site. Next, the interior / exterior substrate / formwork panel X is fixed by a built-in supporter, and concrete is placed. FIG. 3 shows a partially enlarged perspective view showing a state in which the interior / exterior substrate / formwork panel X is built and concrete is placed, and FIG. 4 is a plan view of this state. Here, as the formwork panels other than the interior / exterior base / formwork panel X, a general formwork panel is used here for convenience of explanation, but a flat surface is disclosed in JP-A-2006-9570. It is preferable to use an interior / exterior substrate / formwork panel and use an interior / exterior substrate / formwork panel Y, which will be described later, at the protruding corner. As shown in FIG. 4, the interior / exterior substrate / formwork panel X built before placing concrete is attached with a separator S through a separator through-hole 11a and a separator through-hole 12b. When the tie F is attached, the lateral end thick material H is fixed by a supporting work provided at a predetermined interval.
After placing the concrete, after curing and hardening the concrete, remove the support. In this state, the interior / exterior base member 20 is fixed to the concrete frame by the separator S and the anchor portion 22b. Next, the bolts etc. which fix the formwork panel 10 and the interior / exterior base member 20 are removed, and the formwork panel 10 is removed while leaving the interior / exterior base member 20 in the concrete frame. Thereafter, the interior and exterior are fixed to the interior and exterior base member 20 using the screw holes 21a and the finishing work is performed.

  By the way, when removing the formwork panel 10 from the interior / exterior base member 20 as shown in the plan view of FIG. 5, when the formwork panel 10 is moved in the direction of removing the formwork panel 10 (movement direction A). It is necessary that the side surface 23 of the inner / outer base member 20 does not support. As shown in FIG. 5, the side surface 23 of the interior / exterior base member 20 according to the present embodiment has a movement direction A as a bisector of both wall surfaces, and a boundary with the front surface with respect to a straight line along the movement direction. Since it is inclined to the outside by an angle α, the formwork panel 10 can be easily pulled out. The side panel 23 can remove the formwork panel 10 if the angle α is 0 ° or more. Moreover, the moving direction A can be changed as appropriate, and the range of the angle of the side surface 23 will change accordingly.

  Next, the formwork method of another concrete structure using the interior / exterior foundation combined formwork panel X will be described. In addition, the anchor part 22b shall not be formed in the interior / exterior base member 20 used here. First, the interior / exterior foundation member 20 and the formwork panel 10 are joined together to form the interior / exterior foundation combined formwork panel X. Next, the interior / exterior underlaying formwork panel is built in the shape of a housing. At this time, as shown in FIG. 6, the heat insulating plate D is sandwiched between the placement surface side of the formwork panel 10. Then, separator S, foam tie F, lateral end thick material H, etc. are installed, fixed by supporting work, and concrete is cast and cured. Thereafter, the heat insulating plate D and the interior / exterior base member 20 are left in the concrete frame, and the interior / exterior material is fixed to the interior / exterior base member 20 and finishing work is performed. Since the inner / outer base member 20 and the heat insulating plate D are fixed by the separator S, the nut fixing the separator S and the inner / outer base member 20 is loosened, and the inner / outer base member 20 and the heat insulating plate D are loosened. It is possible to adjust the unevenness by inserting inclusions such as packing. At this time, since the side surface through-hole 23a is provided on the side surface of the inner / outer base member 20, the adjustment work can be easily performed using a tool such as a spanner from the hole.

In addition, the formwork panel 10 in the present embodiment is cut from the state of FIG. 7A at the construction site as shown in FIG. 7B, and the plate body 13a constituting the outer frame is separately fixed to the cutting edge. Then, it can be used after adjusting the interval. The same applies to the formwork panels in other embodiments described below.
Furthermore, as shown in the exploded partial perspective view of FIG. 8A, the inner / outer base member 20 may be configured by two members 20A and 20B having a rectangular cross section. By combining 20A and 20B, as shown in FIG. 8B, the same shape as the above-described inner and outer base member 10 can be realized. At this time, the joint surface 10d forms a split surface. Since 20A and 20B are fixed to the formwork panel 10 and fixed to the concrete frame, it is not necessary to fix them to each other.
Moreover, in the said embodiment, although the interior / exterior foundation | substrate member 20 and the formwork panel 10 were integrated previously in the factory etc., the interior / exterior foundation | substrate member 20 was previously installed using the separator S in this field, and this The formwork panel 10 may be attached to the inner / outer base member 20. At this time, the attachment efficiency between the separator S and the inner / outer base member 20 can be increased by the side surface through-holes 23 provided in the side surface of the inner / outer base member 20.
