Description

[Detailed Description of the Invention] When concrete, plaster, etc. are used for the frame or outer layer of a building, a formwork is installed, and after solidification, the formwork is removed and the surface is coated as necessary. Mortar painting is usually done, but it is not easy to level and draw lines at the external or internal corners of buildings, and even if you do it by applying wooden planks, it is difficult to use a trowel for leveling. Handling requires considerable skill, and in the case of protruding corners, construction time is reduced because it is necessary to prepare one side of the corner, wait for it to solidify, and then prepare the other side and draw the corner lines. On the other hand, drawing out lines at inside corners was difficult due to the lack of a reference line, which lowered construction efficiency.

The demand for improving construction efficiency arises not only from the social perspective of a shortage of construction workers, but also from the perspective of construction speed, and a solution has been desired.

As a result of various studies on these points, the inventor invented the method described below and succeeded in solving the above problems.

The content of the present invention will be explained using the drawings.

When pouring concrete (cement mortar or plaster may be used in addition to concrete, but we will explain below when using concrete), form the protruding corners using templates 1, 1, etc. as shown in Figure 1. For example, when assembling the formwork 8 used for forming the inside corner as well as the outside corner with the templates 1, 1 as shown in Fig. 2, etc. Space A (Space A may be the entire space, or it may be a space created around a core, but below we will explain the case where the entire space is a space). Concrete is poured and a building is formed. In the case of Figure 1, the building's projecting corner is formed, and in the case of Figure 2, the building's projecting and entering corners are formed. Examples include:

In these cases, the mortar (mortar includes cement mortar, gypsum mortar, etc., but hereinafter simply referred to as mortar) at the projecting or entering corner of the building and its surroundings is leveled, and the corner lines are long if used with a trowel, etc. Skill is required to apply the length of the timber and how to handle it in combination with a trowel, and it generally takes a long construction time to finish the two corners using only the length of the timber.

In the case of the present invention, concrete is poured with the corner edge finishing embedding material and the spacer temporarily fixed against the inner corner of the formwork 8, and the concrete is set together with the corner edge finishing embedding material. , After that, remove the formwork 8 and the spacer, fill the recessed part outside the corner edge finishing embedded molding part where the spacer was with concrete or mortar, and fill it along the line of the molding material. By finishing this, we were able to solve the above problems.

The shape of the embedded molding material for corner edge finishing used here is the embodiment shown in FIGS. 1 to 3, etc.

In the case of the shape shown in FIG. 3, it consists of a narrow rectangular plate 3 and wide rectangular plates 3', 3'',
They are arranged radially in three directions on each long side, and plates 3' and 3'' intersect with the protruding corner 2 at approximately 90 degrees, and plate 3 intersects with plates 3' and 3'' at approximately 135 degrees. The free end of the cage plate 3 is pressed against the corner 82 of the formwork 8 shown in FIG. 1 Lower right state) Plate body 3',
Spacers 5, 5 are provided between 3'' and the formwork to fix the position of plates 3', 3'' (as shown in the top left of the figure).
Concrete is poured into the space inside the formwork 8, and after the concrete 9 has solidified, the formwork is removed and brought to the upper left position in Figure 5, and the spacer is removed and the concrete is brought to the lower right position in the same figure. go. Next, the concave portion 7 is filled with mortar so as to embed the corner edge finishing embedding material 4, and while applying a trowel to the long sides of the plate body 3, the area around the protruding corner is smoothed, and the finished portion 7 is smoothed. By completing ', the state shown in FIG. 5 1' can be obtained. The thickness of the finished portion 7 is 1 to 30 mm, preferably 2 to 5 mm.

By using this method, it was possible to finish the projecting corner 2 of the building beautifully and quickly.

When a formwork having the shape shown in FIG. 2 is used, the projecting corner of the building is formed in the same manner as described above (in the case of FIG. 1), but the internal corner is formed by forming the projecting corner inside the formwork 8. At 82', a narrow rectangular plate 3 and a wide rectangular plate 3', 3'' are radially integrated on their long sides, and the plates 3', 3'' are approximately connected to the inner corner 2'. same
The board 3 intersects at an angle of 90 degrees with the boards 3' and 3'' at an angle of approximately 45 degrees. Place the pressing plates 3' and 3'' parallel to the formwork templates 1, 1 so that their free ends are in contact with each other (Fig. 4, 2), and pour concrete into the space inside the formwork 8. After the concrete 9 has solidified, remove the formwork and remove the spacers 5, 5 one after another to create a concave part 7 and bring it to the state shown in Fig. 5-2, and embed the corner edge finishing embedding material 4'. By filling the recess with mortar, applying a trowel to the long sides of the plate body 3, leveling the area around the inside corner, and completing the finished part 7', the state shown in Fig. 5 2' can be obtained. . By using this method, the interior corner 2' of the building was successfully finished beautifully and quickly. The spacer used here is necessary only for positioning the plates 3', 3'', and may be made of a metal plate, a plastic plate, a foamed plastic plate, or the like as appropriate.

When FIG. 4 3 is used instead of FIG. 4 1 as the corner edge finishing embedded material used in the formwork 8 of FIG. 1,
That is, when using the plate 3 shown in FIG. 4 1 having projections 6 extending toward the inner corners of the plates 3' and 3'', the plate 3 shown in FIG. 4 3 is used.
The spacers 5, 5 are fixed to the corner 82 in the state shown in FIG. After that, mortar is filled so as to embed the outer recessed part 7 of the corner edge finishing embedding material 4'', and when finishing in the same manner 7, the protrusion 6 is buried in the mortar, and the corner edge finishing embedding material 4'' is The fixation of the embedded mold material is further improved.

In addition, if the rectangular plates 3, 3', and 3'' have holes of appropriate size, the mortar connection with the concrete on both sides of the plate will be improved, and the fixation of the embedded material for corner edge finishing will be improved. This helps improve the protrusion 6.
It is also valid for Furthermore, instead of using spacers, it is also effective to integrally form positioning feet on the rectangular plates 3' and/or 3''.

The method for temporarily fixing the above-mentioned shapes and spacers to the formwork is not particularly limited, but ordinary means such as adhesives, adhesives, nailing, etc. are sufficient.
The fixing method does not limit the invention.

The contents of the present invention have been described in detail above, but the gist of the present invention is to form an external corner 2 or an internal corner 2' of a building 9 made of concrete or the like using templates 1, 1... In a method of forming a corner of a building in which a formwork 8 is assembled and concrete or the like is poured into the formwork 8, a narrow rectangular plate 3 and a wide rectangular plate 3', 3'' are used. radially in three directions on each long side of
The plate 3 has an angle that approximately bisects the angle formed by the plates 3' and 3'' at the outer or inner angle, and the corner edge finishing embedding is fixedly integrated therewith. The free end of the long side of the plate 3 of the embedded mold material 4 or 4' is brought into contact with the inside corner 82 of the form 8 for forming the outside corner 2 or the outside corner 82' of the form 8 for forming the inside corner 2'. ,
The plates 3', 3'' are temporarily fixed in parallel to the surfaces of the formworks 8, 8 with spacers 5, 5 interposed between them, and then the formwork 4 or 4' and the spacers are placed in the formwork 8. After pouring the concrete, etc. with the remaining portions 5 and 5, and after the concrete, etc. begins to solidify, the formwork 4 is removed, excluding the formwork 8 and the spacers 5, 5.
Or a building made of concrete, etc., in which the concave portion 7 formed on the side of the plate 3 of 4' is filled with concrete, etc., and the mortar surface is smoothed along the free edge of the plate 3 to form a protruding or inward corner. By using this method, it has become possible to quickly and beautifully finish the corners of buildings, which are particularly important in appearance.
