Description

Formwork for concave joint and exposed concrete constructing method using the same

The present invention relates to a mold for concave joints and a method of modularized construction of exposed concrete concave joints using the same. More specifically, the arrangement and arrangement of the cone holes and concave joints become uniform, thereby providing a sense of vibrancy and regularity to the exposed concrete wall. The present invention relates to a formwork for concave joints that can be produced, and a method for modularized construction of exposed concrete concave joints using the same.

Exposed concrete method is a finishing method of construction that reveals the concrete properties, which are the basic aggregates of the building.

In other words, the exposed concrete method is a form that shows the finish with the color and texture of the concrete itself. The exposed concrete method is an architectural form that emphasizes the unique beauty and dignity of the concrete itself by exposing the formwork after it is cast. .

At present, although many architects prefer the exposed concrete method, when performing the conventional exposed concrete method, uneven surface is generated after removing the formwork or the joint is not uniform.

As a result, the hassle and inconvenience of surface repair work must be performed, which inevitably increases time and cost.

In order to overcome this drawback, the recently developed method is the PC method (Precast Concrete).

The PC method is a method of attaching concrete panels made in advance in other places or factories to the inner and outer walls of the steel frame, which is the skeleton of the building, as a finishing material.

In addition to the PC method, cement and natural pulp are compressed and processed into NC boards, and cement boards produced in the same way as general plywood sizes are processed by NC engraving machines. It is a method of attaching to the inner and outer walls of the steel frame as a finishing material.

However, in the case of the above methods, the construction is difficult, and the maintenance is frequent, and most of all, it can be monotonous or crude, so it is difficult to expect a feeling like exposed concrete that consumers think.

As a result, in the near future, research on exposed concrete methods is continuing, and it is common to see them around.

On the other hand, when designing the exposed concrete wall according to the exposed concrete method, three elements of a point, a line, and a surface should be well combined to complete a construction work.

In particular, the arrangement and arrangement of cone holes and concave joints corresponding to points and lines play an important role in producing the liveliness and regularity of exposed concrete walls.

Therefore, the techniques for this are Korean Patent Office Application No. 10-2007-0064301, Korean Patent Office Application No. 10-2007-0064302, Korean Patent Office Application No. 10-2010-0028650, Korean Patent Office Application No. 10-2011- 0084125 and the like.

However, in the case of simply applying the exposed concrete method according to the prior art, including the technology of the above documents, the arrangement and arrangement of the cone hole and the concave joint corresponding to the point and the line as shown in the image shown in Figs. It is difficult to produce the liveliness and regularity of the exposed concrete wall, and this leads to a problem in that the completeness of the building is degraded.

In addition, the conventional formwork has an uneconomical problem because the new formwork should be used by drilling a new hole when the position of the cone hole is changed.

Referring to these drawings, when forming the exposed concrete wall 100 through the exposed concrete concave joint modular construction method using the concave formwork 110 according to the present embodiment, on the surface of the exposed concrete wall 100 It can be seen that the plurality of cone holes 101 and the concave joint 103 are regularly arranged at equal intervals.

As described above, the cone hole 101 and the concave joint 103 formed on the surface of the exposed concrete wall 100 are factors that produce the liveliness and regularity of the exposed concrete wall 100.

Therefore, their management is important, unlike the conventional Figs. 1 and 2, as shown in Figs. 3 and 4, such as the present embodiment, the cone hole 101 and the concave joint 103 on the surface of the exposed concrete wall 100, etc. When arranged at regular intervals, it is possible to produce the liveliness and regularity for the exposed concrete wall (100), which can increase the completeness of the building much higher than the conventional one can enhance the aesthetic beauty of the building.

In particular, the exposed concrete wall 100 is regularly arranged at regular intervals with equal intervals as shown in Figs. 3 and 4 does not require a separate process or complicated method by post-work as before. Therefore, there is an advantage that can shorten the air while improving the work efficiency.

5 is a plan view of a concave formwork according to an embodiment of the present invention, Figure 6 is an image of the enlarged portion of Figure 5, Figure 7 is a partially exploded perspective view of FIG.

Referring to these figures, as a means for making the exposed concrete wall 100 as shown in Figs. 3 and 4, a formwork 110 for concave joints is required.

The concave formwork 110 can be used by connecting the unit size as shown in Figs. 5 and 7 in the lateral direction to match the outer wall size of the building.

The concave formwork 110 is a concave bar for forming a plurality of concave joints coupled to one surface of the formwork body 111 to correspond to the formwork body 111 and the concave joint 103 of the exposed concrete wall ( 113,113 ').

Formwork body 111 may vary from metal to plastic or wood.

Convex bars for forming concave joints 113 and 113 ′ are coupled to the surface of the form body 111 and form concave joints 103 on the exposed concrete wall 100 during concrete curing. The gap between the concave joints 103 on the exposed concrete wall 100 may be regular and uniform only when the gap between the convex forming convex bars 113 and 113 ′ is constant.

In this embodiment, one surface of the convex forming convex bars 113 and 113 ′ in contact with the form body 111 forms a flat plane, and the opposite surface is rounded.

At this time, at least one end portion of the convex forming convex bars 113 and 113 ′ may form an inclined surface 113a which is inclined at an angle of 45 degrees so that the four may cross each other and form a straight line.

Therefore, when four convex forming convex bars 113 and 113 ′ are in contact with each other, as shown in FIGS. 5 and 6, an accurate cross shape can be achieved, and thus the gap between the concave joints 103 on the exposed concrete wall 100 and The shape will be straight and uniform.

In the present embodiment, reference numeral 113 denotes that the inclined surface 113a is formed at both ends, and that the inclined surface 113a is formed only at one end and the other end is treated as one surface is 113 '.

Meanwhile, in the present embodiment, the convex joints 113 and 113 ′ for forming the concave joint may be coupled or bonded to the form body 111 by nails, takapins, bolts, or the like. The former method may be a more convenient method, but ordinary nails may be used instead of bolts.

Although not necessarily, the die body 111 may further include a seat groove 111a in which the convex bars for forming concave joints 113 and 113 'are disposed as shown in FIG. 7.

If the seat groove 111a is formed, the position of the concave joint convex bars 113 and 113 'is not changed, and there is an advantage that it can be fixed at the correct position.
