A construction formwork characterized by comprising a setting scale groove that is horizontally long formed on the front surface of the body and that sets the height of the upper surface of the separator that is fastened to the nut seated in the seating groove of the body. It relates to a separator fixing device.

A mold separator fixing device according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. Detailed technical descriptions of well-known functions and configurations that may unnecessarily obscure the subject matter of the present invention are omitted.

1 to 6 are diagrams showing a mold separator fixing device according to an embodiment of the present invention. FIG. 1 is a perspective view of a separator fixing device for a building form according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view of the separator fixing device for a building form shown in FIG. 3 to 6 are diagrams showing the state of use of the separator fixing device for the building formwork shown in FIG.

As shown in the drawings, the formwork separator fixing device 100 according to the embodiment of the present invention is used for constructing concrete structures such as columns, beams, and walls of various buildings. It fixes the separator 2 used to keep the distance constant, and has a seating groove 4a in which a rectangular nut 3 formed on the end of the separator 2 is seated. has a body 4 whose top is open and both ends spread out in a "V" shape, and a fixing pin 5 formed on the rear surface of the body 4 for binding and fixing the body 4 to the inside of the formwork 1. A separator fixing device comprising:

As shown in FIGS. 1 and 2, the height of the upper surface of the separator 2, which is formed horizontally on the front surface of the body 4 and is fastened to the nut 3 seated in the seating groove 4a of the body 4, is set. A setting scale groove 10 is formed.

A nut 3, which is normally provided on the separator 2, is inserted into the seating groove 4a of the body 4 and disposed. The nut 3 is threaded at the end of the separator 2 so that the nut 3 can be easily inserted into the seating groove 4a even when the seating groove 4a is located forward or rearward from the position of the nut 3. It is configured to be fastened to the portion 2a, transported forward or rearward along the screw portion 2a, set in position, and easily inserted into the seating groove 4a.

Due to the characteristics of the nut 3 as described above, the nut 3 contacts the seating groove 4a during the process of inserting and seating the nut 3 of the separator 2 into the seating groove 4a of the body 4. When the nut 3 rotates and tilts like a "⋄" shape, the width (W) of the nut 3 becomes so large that it is often impossible to insert the nut 3 to the bottom of the seating groove 4a.

If the operator finds that the nut 3 has not been inserted to the bottom of the seating groove 4a, the nut 3 can be positioned correctly and inserted to the bottom of the seating groove 4a, but this is complicated and busy. It is rather difficult to check the correct insertion (entry) of the nut 3 on site, and if the nut 3 is not inserted to the bottom of the seating groove 4a, the position of the separator 2 is slightly high. will be located. In such a case, the stopper 4b formed in the seating groove 4a cannot support the upper part of the separator 2 in the process of narrowing the widened seating groove 4a. There is a risk that the separator 2 may come off due to the external force of .

The mold separator fixing device 100 of the present invention clearly and easily identifies the height of the separator 2 which is inserted into the seating groove 4a of the body 4 and fastened with the nut 3 to be seated by the setting scale groove 10. can do. As shown in FIG. 3, as an example, when the upper surface of the separator 2 is formed higher than the setting scale groove 10, the nut 3 cannot be inserted to the bottom of the seating groove 4a, and the separator is closed. 2 is positioned high, the nut 3 must be re-inserted, and as shown in FIG. , the nut 3 is correctly inserted to the bottom of the seating groove 4a.

Therefore, the operator can easily recognize the inserted state of the nut 3 by the height of the separator 2 which is easily compared with the setting scale groove 10 .

Further, as shown in FIGS. 1 and 2, the setting scale groove 10 is composed of a horizontal plane 11 and an inclined plane 12 formed obliquely upward from the end of the horizontal plane 11 to form a "∠" shape. It is formed.

That is, as shown in FIGS. 3 and 4, since the line of sight of the operator is positioned slightly below the body 4 during operation, the setting scale groove 10 formed on the body 4 is not obstructed and can be clearly identified. It is preferable to form the "∠" shape as described above.

Furthermore, since the body 4 itself is formed a little small, the setting scale groove 10 formed in the body 4 is also formed a little small. A clear identification of the groove 10 is guided.

Further, as shown in FIGS. 1 and 2, an identification band 30 of a predetermined color is laminated on the horizontal surface 11 of the setting scale groove 10 to guide easy identification of the setting scale groove 10 .

That is, as shown in FIGS. 3 and 4, the operator can more clearly identify the setting scale groove 10 by the identification band 30 having a clear hue, so the mold separator of the present invention can be used. Convenient and efficient use of the fixation device 100 can be induced.

On the other hand, as shown in FIGS. 1 and 2, locking projections 21 are formed by punching on both sides of the seating groove 4a of the body 4 so as to protrude inward from the seating groove 4a. A locking groove 22 into which the locking protrusion 21 is inserted is formed in the center of each side surface.

That is, as shown in FIG. 3, when the nut 3 is completely inserted and seated in the seating groove 4a of the body 4 and the widened seating groove 4a is narrowed, the engagement formed in the seating groove 4a is closed. The stopper projection 21 is naturally inserted into the locking groove 22 of the nut 3, so that the nut 3 and the separator 2 are tightly bound and fixed to the body 4. As shown in FIG.

Therefore, as shown in FIG. 6, it is possible to stably prevent the separation of the separator 2 due to the external force of the concrete poured into the mold 1 .

In the mold separator fixing device 100 of the present invention having the above structure, the height of the setting scale groove 10 formed in the front part of the body 4 and the nut 3 inserted into the seating groove 4a of the body 4 are adjusted. The height of the provided separator 2 can be easily compared and identified, and the state of the nut 3 seated in the seating groove 4a can be quickly and clearly determined and dealt with. By solving various problems caused by the inability of the nut to be inserted to the bottom of the seating groove of the body in the above, it is possible to secure excellent durability of the concrete building to be constructed.

In addition, the locking protrusions 21 formed on both sides of the seating groove 4a of the body 4 are inserted into and bound to the locking grooves 22 formed on the nut 3. Since the detachment of the nut 3 can be prevented more stably, the problem that the separator may detach due to the concrete that is poured in the conventional separator fixing device is solved, and the concrete building to be constructed is excellent in durability. There is an effect that can ensure the sex.

Here, the height of the setting scale groove 10 of the body 4 and the height of the separator 2 provided with the nut 3 inserted into the seating groove 4a are compared and identified. If it is formed high, it is recognized that the nut 3 is not inserted into the bottom of the seating groove 4a.

Then, as shown in FIG. 4, the operator corrects the position of the nut 3 and inserts and arranges it in the bottom of the seating groove 4a. Thus, when the nut 3 is inserted to the bottom of the seating groove 4a, the setting scale groove 10 and the separator 2 are positioned on the same line, so the nut 3 is completely inserted into the bottom of the seating groove 4a. You can easily recognize that it has been done.

After that, as shown in FIG. 5, when the seating groove 4a of the body 4 is narrowed using a jig device (not shown), the locking projection 21 formed in the seating groove 4a engages the body 4. Then, as shown in FIG. It is naturally inserted into the retaining groove 22 and tightly bound with the nut 3 to stably fix the separator 2 connected with the nut 3 .

Here, since the nut 3 is inserted into and fixed to the bottom of the seating groove 4a, it goes without saying that the stopper 4b formed in the narrowed seating groove 4a also firmly supports and fixes the separator 2. stomach.

After that, as shown in FIG. 6, the separator 2 is stably prevented from moving up and down by the external force of the concrete poured into the formwork 1, so that the pillars, beams, and walls of the building to be constructed have excellent earthquake resistance. It goes without saying that performance can be ensured.

In addition, the mold separator fixing device 100 according to the present invention further includes an inner circumferential insertion color band 40 .

The inner circumference insertion color band 40 is provided inside the seating groove 4a of the body 4, and is positioned horizontally in a position parallel to the setting scale groove 10, and the nut 3 is in a normal position below the seating groove 4a. It has an easy-to-distinguish hue to confirm that it has been seated on.

Therefore, the inner circumference insertion color band 40 cannot be seen before the nut 3 is completely inserted, but when the nut 3 is completely inserted, the inner circumference insertion color band 40 can be seen from the outside. Therefore, it can be easily recognized from the outside that the nut 3 has been completely inserted.
