Description

The connector for a concrete form

The present invention relates to a formwork connector, and more particularly, to a method of manufacturing a formwork connector, which is capable of easily connecting and fixing adjacent formwork panels when a standardized formwork panel is vertically or horizontally extended, So as not to interfere with the installation.

Generally, in order to cast concrete during construction of a building, a frame is formed with a certain size of formwork, and concrete is laid on the inner side to form a structure of the building in the form of a form.

In this case, the form is spanned by a plurality of panels of a certain size, and when the concrete is poured, a high internal pressure is generated in the form due to the weight of the concrete, so that the form is pushed or partially deformed, .

Accordingly, in order to prevent the form from being pushed out, a plurality of legs are fixed to the outer surface of the form, and the flat tie is inserted and fixed to maintain the spacing of the form.

It is used to support the load of the building. In case of the outer walls and inner walls that block the wind, it is necessary to place the concrete with a considerably thick space and to construct the concrete by durable concrete to withstand the load of concrete until it is fully cured. It is general to provide reinforcement support means.

However, since it is not necessary to support a large load in the case of the inner wall other than the load-bearing wall, it is less likely to support the form because the width is not thick. However, after the concrete curing is completed during the construction, There was an inconvenience to do.

If a cement board made of cement and a styrofoam board can be used as a formwork, it would be easier to construct the interior finishing material without removing the formwork. In this construction, the adjacent formwork panel is connected and fixed But it is not necessary to protrude from the inner wall surface and to remove it after construction.

(Patent Document 1) Korean Patent Registration No. 10-0511462-0000 (Aug. 24, 2005) (Patent Document 2) Korean Patent Registration No. 10-1320697-0000 (Oct. 15, 2013) (Patent Document 3) Korean Patent Registration No. 10-1375463-0000 (March 11, 2014) (Patent Document 4) Korean Patent Registration No. 10-1386757-0000 (April 11, 2014)

SUMMARY OF THE INVENTION The present invention has been developed in order to solve the above problems, and it is an object of the present invention to provide a method and apparatus for forming a plurality of dies in a mold, And to develop a mold connector that does not protrude to the inner wall surface after curing and does not need to be removed.

In order to accomplish the above object, the present invention provides a cement board and a styrofoam board, wherein the cement board and the styrofoam board layer form a dowel, and when the concrete is cured, For example. The form connector has a rectangular plate shape and has a thickness equal to or less than that of the cement board. The form connection port is spaced inward from both ends of the back surface of the body, And a retaining plate having a front center portion integrally connected to the gap retaining portion and elongated in an up-and-down direction and having chamfer portions formed at an upper end and a lower end corner thereof.

In addition, a partition is formed to protrude rearward from the center of the rear surface of the body and to extend downward, and a lower wedge portion is formed with a first wedge portion.

In addition, the partition portion may extend to an upper portion, and a second wedge portion having a narrow width may be formed at an upper end thereof.

As described above, according to the present invention, the mold is mounted on the corner where the formwork panels forming the four formers meet, so that the formwork is not displaced due to the pressure and the inner wall is closed There is an effect that the construction is easy.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown.

FIG. 1 is a perspective view of an embodiment of the present invention, FIG. 2 is a rear perspective view of an embodiment of the present invention, FIG. 3 is a state of use according to an embodiment of the present invention, 11 and a styrofoam board 12 serves as a formwork and is used as a mold connection when the concrete is cured and used as an inner wall finishing material.

Here, the formwork connector 2 has a rectangular plate shape and includes a body 21 having a thickness equal to or smaller than that of the cement board 11. [ The mold connector has a gap holding portion 22 spaced inwardly from both ends of the back surface of the body 21 and extending rearward to a length equal to the thickness of the styrofoam board 11, And a locking plate 23 having a front central portion integrally connected to the gap holding portion 22 and elongated vertically and having a chamfer 231 at an upper end and a lower end corner.

The formwork connector 2 may be mounted at the edge of the four formwork panels 1 as shown in the figure, or may be formed on the side where the two formwork panels 1 meet.

The styrofoam board 12 is provided with an insertion groove 121 into which the gap holding portion 22 is inserted, As shown in Fig.

The seating groove 111 may be formed directly on the styrofoam board 12 in the process of mounting the formwork connector 2 in the case of the insertion groove 121.

At this time, the styrofoam board 12 is positioned inside the concrete where the concrete is laid, so that the outer cement board 11 is prevented from getting wet by the concrete laid thereon, and the outer cement board 11 is required to have an additional inner wall finishing work It is to be able to change the wallpaper by acting as a finishing material as it is.

At this time, the adhesiveness to the styrofoam board 12 with the concrete is reduced, but the solid tie is maintained by the flat tie mounted to maintain the spacing of the formwork, and the wall is completed.

FIG. 4 is a rear perspective view according to another embodiment of the present invention, and FIG. 5 is a rear perspective view of a rear body according to another embodiment of the present invention, And a partition (24) in which a first wedge portion (241) having a narrow width is formed is further formed; The partition portion 24 is extended to the upper portion and the second wedge portion 242 is formed at the upper end thereof.

In the embodiment, as shown in FIG. 3, when the formwork connector 2 is positioned at the boundary where the edges of the four formwork panels 1 meet, it can be seated at the correct position.
