More specifically, the invention relates to a pre-assembled column structure of a rebar type using a ring plate and a sloped beam assembly structure using the same, wherein the rebar type assembly is formed by a ring plate connecting a main rebar, a tie rebar configured to surround the main rebar, and a rebar type assembly formed by installing a grid-type bracket at the location where the beam of the rebar type assembly is to be installed, thereby enabling the installation of a beam formwork or PC beam with a U-shaped cross-section of various depths or widths, and thus making beam assembly easier.

[0003] In particular, among reinforced concrete prefabricated construction methods, pre-assembled reinforced concrete column structures ensure self-supporting capabilities, allowing multiple construction processes to be carried out simultaneously and significantly shortening the construction period.

[0004] In a pre-assembled column structure, a bracket is installed at the location where a beam is to be joined. An example of such a bracket is Public Patent No. 10-2012-0099822. In the above-mentioned public patent, a column head plate (15), which serves as a base for attaching the beam (41), is welded to the main reinforcing bar in the panel zone portion where the beam is joined. Additionally, a column head reinforcing plate (16) is additionally welded inside the column head plate to transfer the stress of the beam to the opposite beam, and necessary beam brackets are welded to the outer surface of the panel zone column head plate in the 4, 3, and 2 directions.

[0005] Another prior art is published patent No. 10-2020-0069282. This prior art provides an angle-type pre-assembled column comprising: four primary main angles that are vertically spaced apart from each other at the corner positions of a column, with a portion bent at 90° having an arc shape; a plurality of auxiliary reinforcements arranged parallel to the four primary main angles; a cross-shaped connecting beam provided between the four primary main angles to fix a composite beam; and a support bracket that is coupled to connect the four primary main angles to support the cross-shaped connecting beam.

Specific details for implementing the invention

[0026] The present invention will be described in detail below with reference to embodiments shown in the attached drawings, but the presented embodiments are exemplary for a clear understanding of the present invention and the present invention is not limited thereto.

[0027] The technical configuration of the present invention according to the following preferred embodiments is described in detail as follows.

[0028] FIG. 1 is a perspective view of a grid-type bracket of the present invention, FIG. 2 is an exploded perspective view of FIG. 1, and FIG. 3 is a cross-sectional view of FIG. 1.

[0029] In the pre-assembled column structure of the reinforcing bar type using the ring plate of the present invention, a grid-type bracket (30) is installed at the height where the beam formwork (20) is joined in the reinforcing bar type assembly (10) to facilitate the assembly of the beam formwork (20).

[0030] As shown in FIGS. 1 and 2, the grid-type bracket (30) of the present invention consists of a grid-type diaphragm plate (330) formed in a grid shape and a mounting plate (340) configured to be mounted on the grid-type diaphragm plate (330).

[0031] The grid-type diaphragm plate (330) is formed in a grid shape of vertical plates, with a square formed in the center and both ends protruding outward. As shown in FIG. 2, this grid-type diaphragm plate (330) is composed of a pair of parallel plates (330a) spaced apart by a certain distance and a pair of parallel plates (330b) spaced apart by a certain distance and arranged perpendicularly to the one-side plate (330a). The one-side plate (330a) and the other-side plate (330b) each have a connecting groove (333) (334) formed at the upper and lower portions of the intersecting parts, respectively, so that the connecting grooves (333) (334) can be joined so that they interlock, thereby allowing it to function as a diaphragm that penetrates the internal cross-section of the reinforcing bar assembly (10).

[0032] Additionally, the mounting plate (340) is formed in the shape of a horizontal plate with a square through hole (341) formed in the center, and is configured to be supported by a grid-shaped diaphragm plate (330) so as to be stably supported so that the beam formwork (20) can be mounted on the upper part.

[0033] FIG. 4 is a perspective view of one embodiment of a reinforced pre-assembled column structure using the ring plate of the present invention.

[0034] As shown in FIG. 4, the pre-assembled column structure of the reinforcing bar type using the ring plate of the present invention has a grid-type bracket (30) installed at the height where the beam formwork (20) is joined in the reinforcing bar type assembly (10) to facilitate the assembly of the beam formwork (20).

[0035] At this time, four reinforcing bars (10) are formed so that the main reinforcing bars (120) are each configured at the corners of the squares forming the columns, and the main reinforcing bars (120) are also configured with a gap between each corner main reinforcing bar (120) and the main reinforcing bar (120).

[0036] A reinforcing bar assembly (10) is formed by such a main reinforcing bar (120), a tie reinforcing bar (130) configured to wrap around the main reinforcing bar (120) at regular intervals along the length of the main reinforcing bar (120), and a ring plate (110) connecting the main reinforcing bars (120) at equal or unequal intervals along the height of the main reinforcing bar (120).

[0037] The ring plate (110) of the reinforcing bar assembly (10) is made of a square horizontal plate-shaped plate with a through hole (111) formed in the center, and the main reinforcing bar (120) is joined to the outer surface of the ring plate (110) by means such as welding and fixed.

[0038] The ring plate (110) has a through hole (111) formed in the center so that the concrete can be poured without interruption during concrete pouring, and serves to allow the main reinforcing bar (120) to be joined and fixed.

[0039] At this time, when reinforcing bars (120) are arranged, a groove (116) is formed on the outer surface of the ring plate (110) as shown in Fig. 5, and the bars are inserted into the groove (116) and fixed by means of welding or other methods.

[0040] As shown in FIG. 5, the connection between the main reinforcing bar (120), the ring plate (110), and the main reinforcing bar (120) and the grid-type diaphragm plate (330) can be made by welding the parts of the main reinforcing bar (120) that are in contact with it and the ring plate (110) and the grid-type diaphragm plate (330) that are in contact with it.

[0041] FIGS. 5 to 8 are perspective views of various embodiments of a reinforced pre-assembled column structure using the ring plate of the present invention. FIGS. 5 to 8 show the mounting plate (340) disassembled for convenience.

[0042] In addition, to prevent the welding heat of the main reinforcing bar (120), as shown in FIG. 6, the joint between the main reinforcing bar (120) and the ring plate (110) and the main reinforcing bar (120) and the grid-shaped diaphragm plate (330) is configured such that a sleeve (170) of a certain length in the shape of a tubular body is fitted onto the main reinforcing bar (120), and the sleeve (170) can be welded to the ring plate (110) and the grid-shaped diaphragm plate (130) respectively to be joined.

[0043] The sleeve (170) is made of a hollow cylindrical tube and can be welded in advance to the ring plate (110) and grid-shaped diaphragm plate (330) at the location where the main reinforcing bar (120) is to be joined, and then the main reinforcing bar (120) is inserted into the sleeve (170) and joined by additional welding, or the sleeve (170) can be inserted into the main reinforcing bar (120) in advance and then the sleeve (170) can be welded to the ring plate (110) and grid-shaped diaphragm plate (330) to fix it.

[0044] Additionally, as shown in FIGS. 7 and 8, a clip-shaped fixing clip (180) with an opening formed on one side is attached to the ring plate (110) and the grid-shaped diaphragm plate (330) to which the main reinforcing bar (120) is joined, respectively, and the main reinforcing bar (120) is fitted into the fixing clip (180) and the open end of the fixing clip (180) is fastened with a bolt (186) to secure it.

[0045] At this time, the fixing clip (180) may be configured such that the opening faces the inner center of the cross-section of the reinforcing bar assembly (10), as in FIG. 7, or such that the opening of the fixing clip (180) faces outward, as in FIG. 8, to facilitate fastening the bolt (186).

[0046] In particular, as shown in FIG. 7, when the opening of the fixing clip (180) is configured to face the inner center of the cross-section of the reinforcing bar assembly (10), the fixing clip (180) located on the grid-shaped diaphragm plate (330) is configured to be located at the upper and lower parts of the grid-shaped diaphragm plate (330), respectively, so that the opening side of the fixing clip (180) comes into contact with the upper and lower parts of the grid-shaped diaphragm plate (330), thereby making welding joint easy.

[0047] Additionally, when the fixing clip (180) is configured such that the opening faces the inner center of the cross-section of the reinforcing bar assembly (10), as shown in FIG. 7, the fixing clip (180) located on the ring plate (110) may have a certain section of cut (181) formed from the end inward at a certain height, so that the ring plate (110) is fitted into the cut (181) and welded together.

[0048] FIG. 9 is a perspective view illustrating an embodiment in which the height of the diaphragm plate is different in a reinforced pre-assembled column structure using the ring plate of the present invention.

[0049] In the present invention, as shown in FIG. 9d, when the depth of the beam formwork (20) connected to the reinforcing bar assembly (10) is different, the grid-type diaphragm plate (330) is configured such that one or more protrudes upward from the outer side of the part where the one-sided plate (330a) and the other-sided plate (330b) intersect have the same or different heights, and the mounting plate (340) is segmented to cover the upper part of each pair of one-sided plates (330a) or a pair of other-sided plates (330b), so that it is formed into a unit segment plate (340a), thereby making it possible to easily connect the beam formwork (20) even if the depth of the cross-section of the beam formwork (20) is different.

[0050] A pair of one-sided plates (330a) or a pair of other-sided plates (330b) can be configured so that their longitudinal ends protrude upward, as shown in FIGS. 9a to 9c, thereby allowing the height at which the beam formwork (20) is mounted to be adjusted.

[0051] At this time, to support both sides in the width direction of the beam formwork (20), the one-sided plate (330a) must have the same height on a pair of opposing end sides on one side or the other side in the length direction, and the other-sided plate (330b) must also have the same height on the opposing sides.

[0052] In this way, since the height of the upper portions of the one-sided plate (330a) and the other-sided plate (330b) may differ, the mounting plate (340) is segmented by each side and composed of four unit segment plates (340a), each formed to cover the upper portions of a pair of one-sided plates (330a) or a pair of other-sided plates (330b).

[0053] Additionally, as shown in FIG. 9b, since a central opening may be created when the height of the upper portions of the one-sided plate (330a) and the other-sided plate (330b) differs, a side closing member (390) can be configured to consist of a vertical finishing plate (391) that finishes the ends of a pair of one-sided plates (330a) and a pair of other-sided plates (330b), and a corner finishing plate (392) with an L-shaped cross-section that connects the ends of adjacent one-sided plates (330a) and other-sided plates (330b).

[0054] FIG. 10 is a perspective view illustrating a sloped beam formwork assembly structure using a reinforced pre-assembled column structure using a ring plate of the present invention.

[0055] The pre-assembled column structure-beam formwork joint structure using the grid-type bracket (30) of the present invention is configured such that the grid-type bracket (30) is installed on the reinforcing bar assembly (10) and the beam formwork (20) is installed on the grid-type bracket (30).

[0056] In the present invention, the beam formwork (20) is formed to have a U-shaped cross section, so that a deck or the like is mounted on the upper part and concrete is poured inside the U-shaped cross section. After installing a grid-shaped bracket (30) on a rebar-shaped assembly (10), the end of the beam formwork (20) having a U-shaped cross section is installed to be mounted on the upper part of a mounting plate (340).

[0057] Accordingly, in the present invention, a finishing member (40) is configured on the upper part of the grid-type bracket (30) to connect the side portions between the beam formwork (20) mounted on the grid-type bracket (30) of the reinforcing bar assembly (10) and the adjacent beam formwork (20).

[0058] As shown in Fig. 10, the side end of an adjacent beam formwork (20) is finished with a finishing member (40), so that the gap between adjacent beam formworks (20) can be finished with the finishing member (40), making it possible to construct even if the width of the beam formwork (20) is different from the width of the reinforcing bar assembly (10).

[0059] As shown in the illustration, the finishing member (40) has both ends joined to the side ends of adjacent beam formwork (20) by means of bolting, etc., thereby connecting the adjacent beam formwork (20) and finishing the space between the adjacent beam formwork (20) and the rebar-type assembly (10), making it easy to pour concrete.

[0060] Such a finishing member (40) is configured to have an L-shaped cross section consisting of a one-sided beam joint (410) and a other-sided beam joint (420) extending perpendicularly from one end of the one-sided beam joint (410), so that the one-sided beam joint (410) is connected to the side of the end of the one-sided beam formwork (20) and the other-sided beam joint (420) is connected to the side of the end of the other-sided beam formwork (20).

[0061] Additionally, if the width of the cross-section of the beam formwork (20) is smaller than the width of the reinforcing bar assembly (10), the finishing member (40) is configured to have a W-shaped cross-section by forming an angle joint (430) having an L-shaped cross-section between the one-sided beam joint (410) and the other-sided beam joint (420), and the angle joint (430) may be configured to be spaced apart from the main reinforcing bar (120) located at the corner by the thickness of the cover.

[0062] In particular, the finishing member (40) is formed with a mounting member (460) in an outer horizontal direction on the upper part, and a mounting member (260) is formed on the outer side of the upper part of the beam formwork (20) so that a deck or the like can be mounted by protruding horizontally outward. The mounting member (460) is connected to the end of the mounting member (260) of the beam formwork (20) adjacent to the upper part, so that the upper surface of the mounting member (260) and the upper surface of the mounting member (460) coincide, thereby maintaining integrity when mounting the deck and preventing concrete from leaking out when pouring concrete.

[0063] FIG. 11 is a perspective view illustrating an assembly method of one embodiment of a reinforced pre-assembled column structure using the ring plate of the present invention.

[0064] As shown in FIG. 11(a), a reinforcing bar assembly (10) is installed, consisting of a main reinforcing bar (120) formed vertically, a tie reinforcing bar (130) configured to wrap around the main reinforcing bar (110) at regular intervals along the length of the main reinforcing bar (120), and a ring plate (110) connecting the main reinforcing bars (120) at equal or unequal intervals along the height of the main reinforcing bar (120). Then, as shown in FIG. 11(b), a grid-shaped diaphragm plate (330) is fixed to the main reinforcing bar (110) by means such as welding. Afterward, as shown in FIG. 11(c), a mounting plate (340) is installed to complete the assembly. At this time, if necessary, a finishing member (40) may be installed in advance on the mounting plate (340) as shown in FIG. 11(d).

[0065] The pre-assembled column structure with a rebar type using a ring plate according to the present invention as described above, and the sloped beam assembly structure using the same, are formed by installing a rebar type assembly consisting of a main rebar, a tie rebar configured to surround the main rebar, and a ring plate connecting the main rebars, and a grid-type bracket at the location where the beam of the rebar type assembly is to be installed, thereby enabling the installation of beam formwork or PC beams with various depths and widths, and allowing the bracket to serve as a bracket for connecting beams to the pre-assembled column structure. In particular, even when the depth or width of the beam cross-section differs, the beam formwork can be easily joined to the pre-assembled column structure without using brackets of different specifications for each beam formwork, thus providing a very useful effect of simplifying construction of the joint and ensuring structural safety.

[0066] Although the present invention has been described in detail with reference to the presented embodiments, those skilled in the art may make various modifications and variations without departing from the technical spirit of the present invention by referring to the presented embodiments.
