【Example】

 FIG. 1 is an example (A) of a form set including a basic sap (1) and a slab (6) for finishing a mortar mortar in a concrete frame of a stairway waist wall. The basic sap (1) is a rectangle. A metal fixed plate (2) is formed by extending a rectangular fixed wood plate (3) at right angles to one another from one long side of the plate fixed plate (2) with their longitudinal directions parallel to each other. In addition, nail holes (4) are provided at intervals in the longitudinal direction, and elongated holes (5) extending in the direction perpendicular to the longitudinal direction are provided in the other wood plate (3) in the longitudinal direction. It is installed.

[0006] The formwork (6) is configured such that, from one long side of the base plate (7) of the rectangular plate, in this example, the template plates (8) of the rectangular bent plate bent in the shape of a cross section in the longitudinal direction are extended from each other. In this example, it is made of metal extending in a right angle so that the directions are parallel, and a long hole (9) extending in a direction perpendicular to the longitudinal direction is formed in the base plate (7). ) Are provided at positions corresponding to the long holes (5).

An example of using the form set (A) in the above example will be described. In the example of use in FIG. 2 (a), first, the fixed plates of the basic fixed woods (1) and (1) are placed at predetermined positions at the upper end portions on both sides of the concrete frame (F) of the staircase waist wall. (2) and (2) are applied, respectively, and concrete nails (10) and (10) are fixed from the nail holes (4) and (4) of each fixing plate (2) and (2). (11)... And (11) are driven into the frame (F) to temporarily fix the basic fixed trees (1) and (1) at predetermined positions.

Next, the base plates (7) and (7) of the formwork (6) and (6) are placed on the basic wood (1) and the wood boards (3) and (3) of (1). With the lower portions of the templates (8) and (8) abutting on both side surfaces of the frame (F), the upper ends of the templates (8) and (8) are placed at a predetermined height from the upper surface of the frame (F). In this state, in this state, the laminated wooden boards (3), (3) and the base boards (7), (7) are used as fixing means in this example with the clips (12), (12). ).

After the formwork set is attached as described above, mortar (m) is poured into a concave portion surrounded by the mold plates (8), (8) and the upper surface of the frame (F). After the mortar hardens, remove the clips (12) and separate the formwork (6) and (6), then remove the concrete nails (10) and separate the basic wood (1) and (1). In this case, a cop with the same width as the frame (F) is formed.

In the example shown in FIG. 2B, the basic fixed woods (1) temporarily fixed on both sides of the frame (F) in the same manner as in the above (A), the fixed wood boards (3), (1) 3) On the base, the base plates (7) and (7) of the molds (6) and (6) are shifted to the outside as appropriate, and the lower portions of the mold plates (8) and (8) are thereby attached to the frame (F). ) Separately from both side surfaces, and in this state, clamp the wood plates (3), (3) and the base plates (7), (7) with the clips (12), (12). As described above, mortar is injected into the template (8), (8), part of the wood board (3), (3), and the concave portion surrounded by the upper surface and part of both side surfaces of the frame (F). As a result, a broader skirting can be obtained than the frame (F).

In the example shown in FIG. 1C, the basic fixed woods (1) and (1) are temporarily fixed to both sides of the frame (F) so as to protrude upward from the upper surface of the frame (F). The base plates (7) and (7) of the formwork (6) and (6) are shifted inward as appropriate on the wood boards (3) and (3), and the clips (12). 12) If the mortar is injected while being clamped by ..., a narrower skirting can be obtained than the frame (F).

Another embodiment shown in FIG. 3 is applied to a formwork set for finishing mortar on a vertical or horizontal mortar of a concrete body surface such as a column or a beam. The basic set wood (1a) has nail holes (4a). It has substantially the same structure as the basic fixed wood (1) of FIG. 1 comprising a fixed plate (2a) having a shape and a wood plate (3a) having a long hole (5a). A base plate (7a) having an elongated hole (9a)... Having substantially the same structure as the base plate (7) of the mold (6), and a right angle from one long side of the base plate (7a). It consists of an extended rectangular flat plate template (8a).

An example in which the form set (Aa) of the above example is used for vertical finishing with mortar on the side of a concrete skeleton of a pillar will be described as an example. The side of the concrete frame (Fa) of the pillar of the concrete building may not be vertical as designed, and in such a case, the work of correcting the inclined surface to a vertical surface with mortar is being performed. Normally, as for the inclined side surface (S1) of the columnar body, a blackening worker preliminarily prepares the side surfaces (S2), (S4) on both sides of the inclined side surface (S1) as shown in FIGS. Is marked with a vertical reference line (L1), and the distance (d1) from the reference line (L1) to the vertical correction surface (SV1) when the inclined side surface (S1) is corrected vertically is written. Keep it.

Therefore, the wood plate (3a) of the basic wood (1a) and the base plate (7a) of the formwork (6a) are connected to the long holes (5a) (9a),. , And the nut (14a) is loosely screwed and connected, and the pair of fixed plates (2a) and (2a) of the connection set are connected to the inclined side surfaces (S1) of the adjacent side surfaces (S2) and (S4). ) With the leading edges of the template plates (8a) and (8a) being positioned at a distance (d1) from the reference line (L) while abutting against each other, the respective fixing plates (2a) and (2a) Is fixed to the side surfaces (S2) and (S4) of the skeleton by using concrete nails (10a) in the same manner as in the above example, and then the nuts (14a) are fastened.

[0015] The nut (14a)... At the time of tightening, the side surface (S2) is also an inclined side surface to be corrected, and a vertical reference line (L2) is provided on both adjacent side surfaces (S1) and (S3). In the case where the ink is blackened and the distance (d2) from the reference line (L2) to the vertical correction plane (SV2) is entered, the form (6a) with the side surface (S2) is attached to the fixed wood. The mold plate (8a) is slid outward along the plate (3a), and the mold plate (8a) is placed at a distance (d2) from the reference line (L2). 13a) Tighten with nuts (14a).

After attaching the form set as described above, as shown in FIG. 5A, the form forms (8a) and (8a), a part of the fixing plates (2a) and (2a), and the wood plate (3a). ) Is applied to the mortar (m1) in a part surrounded by the side surface and the side surface (S1). After the mortar is hardened, when the form sets are removed, the inclined side surface (S1) is corrected to a vertical surface by the repair concrete layer (m'1) as shown in FIG. A mold (pa) for mortar correction of the adjacent inclined side surface (S2) is formed at the edge of the side surface (S2) of '1).

Next, in order to correct the inclined side surface (S2), a mold set is mounted in the same manner as described above near the side surface (S2) of the adjacent side surface (S3), and the mold plate (8a) and the inclined side surface (S2) are attached. ) And mortar (m2) is applied to the concave portion surrounded by the mold portion (pa). After the mortar is cured, when the form set is removed, the inclined side surface (S2) is corrected to a vertical surface.

[Effect of the invention]

 According to the concrete mortar finishing form set of the present invention, the base plate of the form is slid on a fixed wood board temporarily fixed with nails to the concrete body and fixed by fixing means. By doing so, it is possible to set the template at a desired position, and thereby, in the mortar finishing of the skirting of the reinforced concrete frame of the stairs, the skirting with the same width as the lumped wall by one type of formwork set, Wide and narrow hems can be finished freely, and in the mortar correction of vertical and horizontal surfaces of concrete skeletons such as pillars and beams of buildings, the mortar correction finish on one side may be used next to it. The mold part for mortar correction finishing of the ground can also be formed by mortar, which contributes to the improvement of work efficiency.
