Description

Flat Formwork Fixtures {FLAT TIE FOR FORM}

The present invention relates to a flat formwork fixing device, and more particularly, to a flat plate formwork fixing device that can quickly maintain the spacing of the formwork while the formwork can be quickly installed.

Generally, formwork is used to make concrete into structures of constant shape and dimension. The formwork is made of a plurality of panels (panel) to each other to form the same shape and shape as the concrete structure, and then the poured concrete is configured to harden and dismantle. Such formwork uses plywood to which a release agent is applied or steel sheet made of steel.

On the other hand, in order to obtain a concrete structure of the desired dimensions, it is important to manufacture the formwork accurately according to the designed dimensions, and among them, it is very important to keep the spacing between the panels constant according to the designed dimensions. Normally, a flat form fixture, called a "flat tie", is used to keep the two panels evenly spaced. As shown in Fig. 1, the form fixing device is a thin, thin and long steel rod, and at each end, a hole 3 into which a wedge W called a wedge pin is fitted is formed. It is.

The flat formwork fixing device 1 is fitted to both holes 3 while being disposed in the upper or side surfaces or the fixing holes P1 formed in the panel P. The spacing of the panels P is kept constant by the wedges W supported by P).

However, this conventional flat formwork fixing device is inserted into the fixing hole (P1) formed in the panel (P) at the time of maintaining the interval of the panel (P), and then the wedge (W) in both holes (3) again. It is pointed out that the work is cumbersome, such as need to plug in. In particular, it has been pointed out that the conventional form fixing device is difficult to accurately maintain the spacing of the panel (P) according to the designed dimensions as the wedge (W) moves from the hole (3).

Accordingly, the present invention has been made to solve the above-mentioned disadvantages, the object of the present invention is to provide a flat form die fixing device that can quickly perform the gap-keeping operation of the panel.

Another object of the present invention is to provide a flat formwork for fixing the panel can be precisely spaced.

♣ Explanation of symbols for the main parts of the drawing ♣

10; Body 12: support hole

14: fixing hole 20: holder portion

22: first finger 24: second finger

30: protrusion

In order to achieve the above object, the present invention, a flat form die fixing device for maintaining the spacing of the formwork panel, the elongated flat body; First fingers protruding from both ends of the body; It characterized in that it comprises a second finger protruding facing the first finger at intervals so as to support the panel with the first finger.

Preferably, the body has a plurality of support holes are further formed to support the panel by inserting a wedge, and a plurality of fixing holes are further formed to fix the fastening means to the other support, both ends of the body The portion is characterized in that the protrusion is further formed to protrude in the opposite direction to the first finger.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the plate-shaped formwork fixing device according to the present invention in detail as follows.

Figure 2 is a perspective view showing the configuration of a flat formwork fixing device according to the present invention, Figure 3 is a cross-sectional view showing an example of the use of the present invention. According to this, the formwork fixing device of the present invention has a flat body (10). The body 10 is thin and thin and consists of a long length, it is composed of steel (鋼材). Here, the length of the body 10 is of course composed of several sizes.

On the other hand, holder portions 20 are formed on both sides of the flat body 10, respectively. The holder 20 is configured to support the top or bottom or side end of the panel P, and is composed of a first finger 22 and a second finger 24 facing each other at intervals. The first finger 22 is formed by bending both ends of the body 10 in one direction, and the second finger 24 is formed by cutting the body 10 and then bending it in one direction. The first finger 22 and the second finger 24 are configured to support the top or bottom or side ends of the panel P disposed at intervals as shown in FIG. 3. In the present invention is shown to support the top and bottom of the panel (P). Here, the interval between the first finger 22 and the second finger 24 is configured to be determined according to the thickness of the panel (P).

Again, referring to FIG. 2, a support hole 12 is formed in the body 10 between the first finger 22 and the second finger 24, and the second finger 24 and the second finger 24 are formed. It can be seen that the fixing hole 14 is formed in the body 10 therebetween. As shown in FIG. 3, the support hole 12 is configured such that a wedge pin, that is, a wedge W can be fitted thereto. The support hole 12 supports the support force of the body 10 with respect to the panel P by inserting the wedge W into the support hole 12 as necessary and supporting the panel P again. Used to increase

And the fixing hole 14 is configured to be fitted with a fastening means (C), such as nails, screws, as shown in FIG. Fixing hole 14 can be nailed, etc., if necessary, it can be fixed by driving on another support (J). In particular, the fixing hole 14 when fixing the device of the present invention to the bottom of the panel (P), it is possible to fix the body 10 to the bottom surface through the fastening means (C) such as nails.

Next, looking at the use of the flat formwork fixing device of such a configuration with reference to Figure 3, first arrange the two panels facing each other according to the designed dimensions. Then, the upper or lower end or side end of the panel P is supported by both holder portions 20 of the formwork. In Figure 3 of the present invention is shown as supporting the top and bottom of the panel (P) with a formwork fixing device.

As such, the panels P supported by the first and second fingers 22 and 24 of the holder part 20 while supporting the panels P facing both holder parts 20 of the form fixing device are It is firmly arranged at regular intervals. Here, if necessary, the wedge W may be inserted into the support hole 12 to support the panel P, thereby increasing the holding force of the fixing device with respect to the panel P. In addition, a nail may be inserted into the fixing hole 14. Of course, by fixing it to the bottom surface can also increase the holding capacity of the fixing device for the bottom surface.

On the other hand, Figures 4 and 5 are a perspective view and a cross-sectional view showing another embodiment of the present invention. According to this, the formwork fixing device of another embodiment has a protruding projection (30) protruding in the opposite direction to the holder portion 20 on both ends of the body (10). When the protrusions 30 support the upper end of the panel P with the fixing device of the present invention as shown in FIG. 5, the lower panel P is guided while guiding the lower end of another panel P stacked on the upper side. ) To align with The protruding protrusion 30 is formed by cutting the first finger 22 of the holder 20 and then bending it in a direction opposite to the first finger 22.

The present invention of such a configuration is to support the top or side end or the bottom of the panel (P) facing through the holder portion 20 formed on both sides of the body 10 to quickly maintain the interval of the panel (P) It has the advantage of being able to keep the gaps between the panels accurately and at the same time.

In the above described a preferred embodiment of the present invention by way of example, the scope of the present invention is not limited only to this specific embodiment, it can be appropriately changed within the scope described in the utility model registration claims.

The flat formwork fixing device of the present invention as described above, by forming a holder portion consisting of the first and second fingers on both sides of the body, by using it to maintain the gap of the panel by supporting the top or side end or bottom of the panel facing The advantage is that the work can be done quickly while at the same time maintaining the exact spacing of the panels.
