Description

One touch type turnbuckle connector for euroform}

The present invention relates to a one-touch type turnbuckle connector for Euroform, and more particularly, in the process of installing the turnbuckle for supporting the vertical structure of the Euroform to the vertical structure, it can be easily installed with a one-touch method.

In particular, the present invention simplifies the structure of the connector and enables one-touch coupling using the features of the external shape, greatly improving the convenience of work, shortening the construction period of the building, and minimizing the manufacturing cost of the connector. It relates to a one-touch type turnbuckle connector for Euroform that can reduce the overall construction cost.

When constructing a concrete structure such as a house, building, or apartment, a frame of a shape corresponding to the shape is formed for the structure to be formed, such as a column, floor, wall, etc., and then the kneaded concrete is poured and cured. The frame used is called a formwork.

Such a formwork is manufactured in various forms and materials according to the type, height, shape, etc. of the building to be constructed. Among these forms, a uniformly standardized form is called Euroform.

On the other hand, in general, in order to install the Euroform, a support frame and a support are coupled together with each Euroform, and a wedge-shaped coupling piece or bolt is used.

In particular, the support frame and the support (turnbuckle) are mainly combined by a bolt fastening method. A problem has occurred.

However, the prior art has the following problems.

First, the brace (hereinafter referred to as a 'turnbuckle') is coupled with a fixture installed on the floor and a vertical support by a fitting method.

For example, after installing any one turnbuckle, if a force is applied to the support to install the other turnbuckle, it may occur that the first installed turnbuckle is separated.

Even after all the turnbuckles are installed, this problem may occur equally if the vertical support is shaken by an external factor.

Second, since the fastener is fixed at the end of the brace, the angle of engagement between the support and the brace is determined. Due to this, when the vertical support height is adjusted, the support and the brace cannot be stably combined, and in some cases The bonding itself may not be possible.

Third, since the shape or structure of the support structure is fixed, it is impossible to adjust the support structure according to the field conditions at the work site, and this has a problem in that there are many restrictions in installing the Euroform.

Fourth, for the same reason, since components of different specifications are required according to each construction site and building, there is a problem in that the effect of using the Euroform is offset and disappears.

Examples of the one-touch type turnbuckle connector for Euroform according to the present invention can be applied in various ways. Hereinafter, the most preferred embodiment will be described with reference to the accompanying drawings.

1 is a perspective view showing an embodiment of a turnbuckle connector for a one-touch type Euroform according to the present invention.

Referring to FIG. 1 , the one-touch type turnbuckle connector (A) for euroform includes a fixed support ( 100 ) and a rotation support ( 200 ).

The fixing support 100 is fixedly installed on the vertical structure of the Euroform, and one end of the turnbuckle that is installed obliquely from the bottom surface toward the vertical structure is fitted, and the turnbuckle is coupled to the front (lower right direction in FIG. 1) and the rear (upper left direction in Fig. 1) is fixed to the vertical structure. Here, the method of fixing and installing the fixing support 100 to the vertical structure may use a separate mechanism according to the euroform and the support structure and the needs of those skilled in the art, or various methods such as welding and bolting may be used, so it is not limited to a specific one. It is natural that no

The rotation support 200 is rotatably coupled to the fixed support 100 by the rotation shaft 300, and is naturally rotated upward while being pushed by the pressing force generated when the turnbuckle is installed, and the turnbuckle is fitted to the fixed support. do.

When the turnbuckle is coupled to the fixed support ( 100 ), the pivoting support ( 200 ) rotates downward by its own weight to return to its original position, and then the turnbuckle is prevented from being separated from the fixed support ( 100 ).

In other words, the rotation support 200 rotates by an external force (force generated by the user pushing to engage the turnbuckle) when the turnbuckle is installed, so that the fitting groove is opened, and after the turnbuckle is engaged, it rotates by its own weight The fitting groove can be closed.

In addition, the fixing support 100 has a fitting groove formed in a direction (eg, a horizontal direction) that crosses the inclination direction in which the support force of the turnbuckle with respect to the Euroform is generated, regardless of the coupling angle of the fixing support 100 and the turnbuckle. can be stably bound.

Hereinafter, each configuration will be described in more detail.

FIG. 2 is a perspective view illustrating the fixing support shown in FIG. 1 .

Referring to FIG. 2, the fixing support 100 includes a fixing part 110 fixed to a vertical structure, and a wing part 120 formed by bending forward (lower right direction in FIG. 2) from the fixing part 110. may include

And, the wing part 120 may be formed with a through hole 123 to which the rotation shaft 300 is coupled, and the fitting groove 121 to be fitted with the turnbuckle as described above may be formed to open forward. .

In particular, the fitting groove 121 may be formed in a horizontal direction to cross the support direction of the turnbuckle.

In FIG. 2, the shape of the fixing support 100 is shown in a 'C' shape, but it is deformable depending on the shape of the turnbuckle to which it is coupled. It may be changed to a T' shape, a 'ㅗ' shape, or the like.

As a result, the inner side of the fitting groove 121 is formed in a curved surface, and the portion to be fitted into the fitting groove 121 among the end portions of the turnbuckle is formed in a curved surface, so that the coupled state can be stably supported even if the coupling angle is adjusted. If it is satisfied that there is, it is natural that other structures or forms may be variously changed.

3 is a perspective view illustrating the rotation support shown in FIG. 1 , and FIG. 4 is a view illustrating the talon shown in FIG. 3 .

Referring to FIG. 3 , the rotating support 200 may include a support plate 210 and a talon 220 .

The support plate 210 limits the rotation of the rotation support 200 in the downward direction by its own weight, and as shown in FIG. 1 , may limit rotation in the downward direction rather than the horizontal direction.

To this end, the support plate 210 may be formed in a sufficient size so as to be supported by the wing portion 120 of the fixing support 100 .

The talon 220 is formed on the lower surface of the support plate 210 , and opens and closes the fitting groove 121 according to the rotation of the support plate 210 , and one or more configurations may be possible as needed.

And the front part (lower left in FIG. 3) of the talon 220, that is, the rotation inducing part 221 of the curve in the direction in which the fitting groove 121 is opened may be formed.

At this time, the rotation inducing part 221 may be formed so that the center point C1 is located at a position H higher than at least one of the fitting groove 121 and the center C2 of the rotation shaft, as shown in FIG. 4 .

As such, when the center point C1 of the rotation induction unit 221 is formed at a high position, the rotation support 200 can be rotated in the upper direction more easily and naturally when combined with the turnbuckle.

The function of the rotation induction unit 221 will be described in more detail below.

On the other hand, when the turnbuckle is coupled to the fixing support 100 as described above, it is necessary to prevent the turnbuckle from being separated until the concrete pouring is completed and the Euroform is dismantled.

To this end, the present invention may protrude the separation preventing part 222 at the end of the rotation inducing part 221 formed on the talon 220 .

In other words, when the turnbuckle is moved forward to be separated, it is possible to restrict the rotational support 200 from rotating upward while the separation preventing unit 222 is caught on the turnbuckle.

At this time, in order to ensure a certain level of fluidity in the movement of the turnbuckle, and to allow the rotation support 200 to smoothly return to the original position regardless of the movement of the turnbuckle, the inner part (222a) connected to the separation prevention part 222 can be formed as a curve.

In addition, the talon 220 may be formed with a through hole 223 through which the rotation shaft 300 is through-coupled.

Meanwhile, in FIG. 3 , the support plate 210 and the talon 220 are shown to be fitted in such a way that the coupling portion 224 is fitted into the coupling groove 214 , but the present invention is not limited thereto. It can be manufactured in one piece.

On the other hand, when the turnbuckle is coupled or when the operator wants to separate the turnbuckle, if the rotation support 200 is rotated excessively, it may not be able to return to the original position by its own weight.

Hereinafter, a method of limiting the rotation angle of the rotation support 200 in order to solve this point will be looked at.

5 is a partially enlarged view illustrating the rotation range of the rotation support shown in FIG. 1 .

Referring to FIG. 5 , the fixed support 100 is pivotally coupled to the talon 220 , and at least one of the support plate 210 and the talon 220 of the rotation support 200 is the talon 220 . It may be formed to limit the opening angle of the

For example, the support plate 210 is limited in rotation while one side (left in FIG. 5) end portion (a) is supported by the wing portion 120 as shown in the enlarged portion, the support plate 210 is in the front-rear direction (left-right direction in FIG. 5). In particular, by adjusting the position of one end portion, it is possible to adjust the rotatable range of the rotation support 200 .

As another example, the rotation of the talon 220 is limited while the outer surface of the rear (left in FIG. 5) is supported by the inner surface of the fixing unit 110 as shown in the enlarged portion, and the rear shape of the talon 220 is changed By doing so, it is possible to adjust the rotatable range of the rotation support 200 .

In this way, if the rotation support 200 is restricted from rotating beyond the vertical direction when opened, it is possible to sufficiently ensure that the rotation support 200 is moved to the original position by its own weight.

6 and 7 are views for explaining the method of use of Fig. 1, and Figs. 8 and 9 are field photos showing the state in which Fig. 1 is constructed.

First, the turnbuckle 400 is formed of a tube and a fitting pin 410 is formed at the end of the turnbuckle 400 to protrude from both sides. The structure of such a turnbuckle 400 is only an example, and may be deformed in various forms, and as described above, when the form of the turnbuckle 400 is deformed, the form of the turnbuckle connector (A) may also be deformed correspondingly.

As shown in FIGS. 8 and 9, the turnbuckle connector (A) of the present invention is fixed to a frame installed in a vertical structure, and when you want to support this frame with a turnbuckle 400, the turnbuckle as shown in the upper part of FIG. When the 400 is moved to the rotation support 200 side, the fitting pin 410 comes into contact with the rotation induction part 221 of the talon 220 .

After that, if the turnbuckle 400 is continuously moved as shown in the lower part of FIG. 6, the talon 220 is rotated upward by the movement of the fitting pin 410, and as shown in the upper part of FIG. 7, the fitting pin ( 410 may be inserted into the fitting groove 121 .

Finally, when the fitting pin 410 is completely fitted into the fitting groove 121, the rotation support 200 rotated in the upper direction is rotated in the lower direction by its own weight, and the turnbuckle 400 is completely coupled. can be

At this time, since the support force by the turnbuckle 400 is applied in the oblique direction (box-shaped arrow in FIG. 7), it can be stably supported.

In addition, since the outer circumferential surface of the fitting pin 410 is curved and the inner circumferential surface of the fitting groove 121 is also curved, even if the coupling angle of the turnbuckle 400 is changed, the coupled state can be stably maintained.

When the turnbuckle 400 is separated, the operator rotates the rotation support 200 in the upper direction while holding the support plate 210 of the rotation support 200 to open the fitting groove 121, then the turnbuckle ( 400) can be easily separated.

As a result, since the turnbuckle connector (A) of the present invention is possible with only one operation even when the turnbuckle 400 is coupled as well as separated, the installation and disassembly of the turnbuckle 400 can be made easily and quickly.

FIG. 10 is a diagram illustrating another embodiment of FIG. 1 .

Referring to FIG. 10 , the rotating support 200 may not include the support plate 210 , but may be configured only with the talon 220 .

In other words, the rotation support 200 of the present invention is shaft-coupled to the fixing support 100 to rotate in a limited range, and may be formed to open and close the fitting groove 121 according to the rotation angle.

At this time, the fixing support 100 may be provided with a lower stopper 125 for limiting the downward rotation of the talon 200 and an upper stopper 126 for limiting the upward rotation of the talon 200 .

For example, the lower stopper 125 and the upper stopper 126 may include protrusions formed to protrude inward from the wing portion 120 of the fixing support 100 .

In addition, a handle portion 225 that the operator can hold may be formed on one side of the talon 220 so that the talon 220 can be rotated upward according to the needs of the operator.

In the above, a one-touch type turnbuckle connector for Euroform has been described according to the present invention. Those skilled in the art to which the present invention pertains will understand that the technical configuration of the present invention may be implemented in other specific forms without changing the technical spirit or essential characteristics of the present invention.

Therefore, it should be understood that the embodiments described above are illustrative in all respects and not restrictive.
