The beam formwork 1 according to the present invention is formed using a steel plate having a predetermined unit width w. The steel plate is, for example, a steel plate that has a certain width manufactured by roll forming or the like, but is formed long in the longitudinal direction and can be cut and used by the length considering the cross section of the beam desired by the user. In general, since the deck plate is manufactured by folding a steel plate of a certain width, it is difficult to accommodate the change according to the cross-sectional size of the beam. Therefore, the length of the deck plate does not match the length direction of the beam, and the length of the deck plate corresponds to the cross-section size of the beam, and a plurality of deck plates having a certain width are installed to approximate the length of the beam, and then the detailed length is determined at the connection Organize in a way that fits.

As shown in FIG. 2B, the beam formwork 1 cuts a steel plate having a predetermined unit width w by a desired length L and uses it as a unit length. The length (L) corresponds to the sum of the height (a, c) of the beam and the width (b) of the beam. As a result, a beam form using a deck plate that can have various widths and heights depending on the width and height of the beam required for the structure while manufacturing a beam form using a steel plate having a certain width, such as a roll forming steel plate manufactured in a factory. System can be provided.

At this time, the length (l) of the beam becomes a length corresponding to n ㅧ w by connecting a plurality of predetermined width w.

The cut steel plate is formed with a bending groove 13 at a position corresponding to the height and width of the beam in the longitudinal direction. The bent groove 13 may be formed by forming the protrusion 14 of the deck plate and then cutting it into a V shape. In addition, as shown in FIG. 3, the bent groove 13 may be formed together with the protrusion 14 when forming the protrusion by forming a cutout hole in the flat steel plate in advance and then folding.

Here, when connecting a plurality of tech plates, it is not limited to the example of FIG. 4b, and when the tech plate is first bent in a beam shape and connected, as shown in FIG. 4c, at the portions abutting in a protruding shape at both ends of the deck plate. The deck plates adjacent to each other can be connected by spot welding (refer to (a, b) of Fig. 4c) or by overlapping joints at the bottom plate (refer to (c) of Fig. 4c).

The beam formwork 1 is formed by folding a deck plate 10 having a protrusion 14 formed at a predetermined interval and a bent groove 13 formed at a bending position. The beam formwork (1) formed by bending at the position of the bending groove (13) has a bottom portion (12) formed as a deck plate, and is bent from the bottom portion (12) in a bent groove to be installed and formed as a deck plate.

The lower reinforcing section steel 21 and the upper reinforcing section steel 22 are to be installed on the beam formwork 1 after folding the deck plate 10 to form the wall section 11 and the bottom section 12. However, as shown in FIG. 5C, the deck plate may be folded and installed after spot welding is performed in advance at both ends of the deck plate 10 and the position of the bent groove 13.

On the other hand, an end reinforcing plate 23 for reinforcing the end of the beam may be installed at the end of the beam form 1 in the longitudinal direction, and the end reinforcing plate 23 is at the end of the beam in the longitudinal direction. It is configured by being connected to the reinforcing section steel 22 and the lower reinforcing section steel 21.

In addition, the beam formwork 1 may be provided with a lattice reinforcing bar 24 for expanding the support interval of the beam and for shearing reinforcement against a large load. The lattice reinforcing bar 24 is installed on the wall portion 11 of the beam formwork 1 and may be installed between the upper reinforcing section steel 22 and the lower reinforcing section steel 21. As shown in FIG. 5C, the lattice reinforcing bar 24 is installed by welding to the upper and lower reinforcing beams before bending the deck plate 10, and then folding the deck plate to form a beam. It is desirable to do.

Here, the reinforced section steel plays a part of the role of the beam main muscle, and the protrusion of the deck plate is used as a stirrup, which is the shear stiffener of the beam, and a lattice material or a strip plate can be added to further shear reinforcement or to increase the support interval.

An upper reinforcing plate 25 is installed at the upper end of the wall part 11 of the beam form 1. The upper reinforcing plate 25 is arranged at regular intervals along the length direction of the beam and is configured to connect between the upper reinforcing beams 22 to prevent the wall part 11 of the beam from spreading to maintain its shape. do.

On the other hand, since the beam formwork 1 configured as described above has a length l of a beam corresponding to n ㅧ w by connecting a plurality of predetermined width w, it may be insufficient for the actual required length of the structure. In this case, a connection plate (31, 32, 33, 34) is provided as a configuration for covering an amount corresponding to the insufficient length.

It is provided with a column connection plates (31, 32) installed at a portion connected to the column at the end of the beam formwork (1).

It can also be fastened by

As a result, the deck plate formed by cutting into a unit length can be connected to a length corresponding to the length of the beam to form a beam, but it can be smoothly applied to a beam structure having various lengths using a column connection plate. The degree of freedom can be improved.

On the other hand, depending on the load acting on the structure, it is possible to install a sub-beam in the middle of the slab. In the case of installing the sub-beam, the sub-beam formwork 3 of the sub-beam may be formed by the same configuration as that of the above-described beam formwork, and redundant descriptions thereof will be omitted.

As in the case of the column connection plate, a gap may occur between the sub-beam formwork and the beam formwork according to the actual required length of the structure, so the part connected to the sub-beam formwork (3) in the middle of the beam formwork (1) In the sub-beam connection plate (34) can be installed.

Since the configuration of the sub-beam connection plate 34 is substantially the same as that of the column connection plates 31 and 32, a redundant description thereof will be omitted.

In addition, an inserting plate 35 may be installed inside the sub-beam connection plate. The inserting plate 35 is connected to the upper and lower reinforcing section steels of the sub-beam formwork 3 at a connection portion with the beam formwork 1 to reinforce the end of the sub-beam.
