Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a formwork apparatus used for constructing an outer wall of a building or the like.

(Prior Art) For example, in a makeup work for an outer wall of a building, a decorative material is sprayed directly or indirectly through a base material onto a concrete mortar wall surface, a masonry block wall surface, or other wall surface that has been subjected to a rubbing process. The method of applying by attachment is adopted. However, if it is too thin, strength, weather resistance, luster retention, etc. are insufficient, unevenness is likely to occur, and cracks are also likely to occur.

(Technical problem) The present invention was made in order to solve the above-mentioned problems, and the purpose thereof is to make it possible to give a desired thickness to a molding material for forming a new wall surface, and to provide a base for concrete mortar or the like. It is an object of the present invention to provide a formwork device for wall surface construction, which has excellent adhesion to the surface, is evenly finished, is less likely to cause cracks, and can form a wall surface having good weather resistance and water resistance.

(Technical Means) The above-mentioned objects are combined in a substantially lattice shape, and a fixed frame member 3 which is attached to the wall surface base material 1 by a fastener 2 such as a screw or a nail with a substantially constant gap therebetween, and a surface of the wall surface base material. The mold surface 4 having a smooth, regular or irregular pattern is detachably fitted to the fitting portion 5 formed on the fixed frame member and set at a substantially constant position with respect to the wall surface base. Can be reached by means of a formwork device configured with

In the above, the wall surface substrate 1 is a surface for placing concrete mortar, a block wall surface, a target portion thereof, and other wall surfaces for forming a new wall surface.

(Example) Hereinafter, description will be given with reference to the drawings. The device of the present invention attaches the surface slab 6 to the wall surface substrate 1 with a substantially constant gap G,
It is for injecting the molding material F into the gap between the base 1 and the surface plate 6. The illustrated fixed frame member 3 is a vertical and horizontal crosspiece 1.
It is a combination of 3 and 14 in a grid pattern, and the grid's eyes are face plates 6
It is almost the same type as. The vertical rails 13 and the horizontal rails 14 of the member 3 are formed by a cross-section substantially U-shaped or H-shaped material in which parallel inner edge portions 7 and outer edge portions 8 are connected by a narrow intermediate portion 9. The fixed frame member 3 having such a cross-sectional shape can be formed by extrusion molding of synthetic resin or a metal mold material. Particularly, the resin-made one is suitable for the device of the present invention because it can be deformed according to the unevenness of the wall surface base.
Since the intermediate portion 9 has a narrow width, it has a groove shape, and constitutes the fitting portion 5 into which the edge 15 of the face plate 6 is fitted.

The stopper 2 is a member for attaching the fixed frame member 3 to the base wall surface 1, and is made of wood screws, concrete nails, etc. Small holes 16 for passing this are provided in the vertical 13 and the horizontal rails 14 at substantially equal intervals. There is. Reference numeral 17 is a screw hole provided on both sides of the outer edge 8 of each of the crosspieces 13 and 14, into which a set screw 12 for fixing the surface plate 6 described later is screwed.

The surface slab 6 mentioned above has a smooth surface as shown in FIG. 1 facing the wall surface base 1, or a regular surface such as tile-like 18 or brick-like 18 'as shown in FIGS. 3 and 4. Formed with a tough transparent material (including translucent), which has a geometrical pattern surface or a formwork surface 4 having an infinite irregular pattern 19 as shown in FIG. What was done is the best. With the transparency, the state of the molding material F injected into the gap G can be observed and adjusted. The face plate 6 is fitted to the groove-like fitting portion 5 at the edge 15, and the set screw
It is tightened at 12, but in order to obtain a tight seal between the fitting portion 5 and the edge 15, packing for sealing the groove bottom and the inside where the edge 15 contacts
Ten are provided. The packing 10 is also provided on the surface of the fixed frame member 3 in contact with the base 1.

When attaching the face plate 6, reinforcing braces 20 are used as necessary to withstand the pressure of the molding material F injected into the gap G. Either the long set screw 12 or the stopper 2 of the fixed frame member 3 may be used for the attachment. Also, it must be done before mounting the surface slab 6, but a fixed anchor 11 having a length that is driven into the wall surface base 1 and projects to a length that fits between the base 1 and the surface slab 6 is suitable. Used in combination. As the anchor 11, a flat screw, which has a large number of adhesive surfaces with the molding material F and which is unlikely to rust, is used. twenty one
Is an injection port, which is provided by partially notching or opening the upper edge of the face plate 6.

(Operation) The apparatus of the present invention configured as described above operates as follows in wall construction.

At the time of construction, a fixed frame member 3 is attached to the wall surface base material 1 from the bottom by a predetermined number of steps by a stopper 2, and the anchors 11 are driven into the base material 1 in the grid pattern. A face plate 6 is attached to the fixed frame member 3 by a fitting portion 5, and a hose is introduced from an injection port 21 at an upper edge of the face plate 6 into a gap G between the mold face 4 of the face plate 6 and the wall surface base 1. The molding material F is injected in the shape of a circle and fills the entire area of the lattice. Injection can be done by connecting a funnel-shaped one to a hose-shaped one and by hand, or by using equipment such as a compressor and airless. After the filling, the mold making material F is flatly pressed and adjusted by a metal iron, a spatula, etc., and solidified.

When the filling with the molding material F is completed and solidified, the face plate 6 is removed, and then the fixed frame member 3 is removed. Since the mark after removing the fixed frame member 3 is the joint P, fill the caulking agent,
Finish coating is applied to the front surface of the newly formed wall surface (Fig. 6). If the caulking agent is made different in color from the mold making agent F, a change in design is provided, and if the caulking agent is made the same color, it is suitable for orders in which the joints are not desired to stand out. Of course, the caulking agent plays a role of waterproofing treatment.

In addition, as a mold making material, a cement filler (undercoating material, undercoating material), a sealer (undercoating material) or a premix material such as a mixture of them with a wall surface undercoating 1 such as concrete for covering the undercoating 1 Water resistant materials with excellent adhesion are suitable. For finishing, for example, a spray material such as enameled is used, which is painted by a roller or a spray.

(Effect) Therefore, according to the present invention, the molding material F that forms a new wall surface can be made to have a desired thickness, can be well adhered to the base 1 such as concrete, can be finished evenly, and cause cracks. A formwork device capable of forming a wall surface that is difficult, weather resistant, and has good water resistance is obtained, and a remarkable effect is obtained in practical work.
