Description

Technology Field

[0001] This invention relates to a reinforcing structure for the joint of a deck plate, and more specifically, to a reinforcing structure for the joint of a deck plate that can prevent the collapse of the deck plate during the construction process of a reinforced concrete structure by providing deck beam supports upright at each end of the deck beam yoke member so as to support the lower panel of a deck slab positioned to be close to the joint. Background Technology

[0003] Generally, reinforced concrete structures are composite structures that utilize both concrete, a compression material, and reinforcing bars, a tension material. They are constructed by preparing formwork using materials such as plywood or lumber, arranging reinforcing bars within the formwork, and repeating the process of pouring and curing concrete, followed by the removal of the formwork.

[0004] Formwork is a temporary structure provided to shape and dimension concrete while it is still fluid until it is cured, and formwork construction is essential for reinforced concrete structures.

[0005] In the prior art, an assembled beam deck plate of Registered Patent Publication No. 10-2236580 (March 31, 2021) was proposed to be applicable to the construction of beams of various specifications, but there was a problem in that concrete poured through the gaps leaked during the process of assembling multiple side plate units to correspond to the height of the beam.

[0006] In addition, when concrete is poured and vibration-compacted on the deck slab and deck beam of a reinforced concrete structure, there was a cause for the side panels of the deck beam at the joint, which is the inner connection part of the deck slab and deck beam, to bulge outwards on both sides, and various troubles occurred, such as the deck slab at the joint also being crushed downwards, leading to the collapse of the structure.

[0027] As shown in FIGS. 1 to 9, the joint reinforcement structure (A) of the deck plate according to the invention is designed to further prevent various troubles, such as deformation where the side plate (SP) of the deck beam (DB) in the joint (JT), which is the inner connection part of the deck slab (DS) and the deck beam (DB) used as temporary materials during the concrete pouring process, bulges outwards on both sides, and the deck slab (DS) in the joint (JT) also gets crushed downwards. It is provided so that the joint (JT) between the deck slab (DS) and the deck beam (DB) of the deck plate (DP) is reinforced.

[0028] The above joint reinforcement structure (A) is provided with a deck beam yoke (10) on the lower part of the bottom plate (UP) of the deck beam (DB), and each end of the deck beam yoke (10) is provided with a left and right extension (110) that extends laterally than the width of the bottom plate (UP) of the deck beam (DB).

[0029] In each of the above left and right extensions (110), a deck beam support (20) is provided vertically upward, and the upper part of each of the above deck beam supports (20) is provided to support a slab yoke (30) provided on the lower part of the deck slab (DS). At this time, it is preferable to provide the deck slab (DS) and the deck beam (DB) with steel plates, and it is even more preferable to maintain a thickness of 1.2 mm.

[0030] On both sides of the deck beam yoke (10), square fasteners (120) are provided to fix the deck beam (DB) with a width equal to the width (W) of the deck beam (DB).

[0031] The above square fixing member (120) has a square through hole (121) formed that penetrates from the top to the bottom, and a triangular reinforcing member (122) is provided on one side of the square through hole (121). A yoke wedge (123) is hammered and fixed from the top to the bottom of the square through hole (121), thereby causing the reinforcing member (112) to move along the length direction of the deck beam yoke material (10) by the yoke wedge (123), that is, to move from the outside to the inside of the deck beam (DB) and be tightened and fixed.

[0032] The deck beam support (20) provided on each of the above left and right extensions (110) is intended to prevent bulging of the side panel (SP) of the deck beam (DB) of the joint section (JT), and by being provided close to the side panel (SP) of the deck beam (DB), it is much more effective for reinforcing the joint section (JT) of the deck beam support (20).

[0033] It is preferable that two or three pipe supports (PT; Pipe Support) be provided in the longitudinal direction of the deck beam yoke (10) at the bottom of the deck beam (DB) under panel (UP; Under Panel) to ensure stable support, and in some cases, as shown in FIG. 9, a number of pipe supports (PS; Pipe Support) may also be provided at the bottom of the slab (SB).

The upper part of the male screw rod (220) is provided with a U-head (221) to support the slab yoke member (30). The male screw rod (220) is provided with a height adjustment part (222) so that the slab yoke member (30) can be fastened to the lower panel (BP) of the deck slab (DS). That is, even if the gap or height between the upper part of the deck yoke member (10) and the lower part of the deck slab (DS) is different, it is properly aligned and supported in an optimal state without shaking.

[0035] The lower end of the square coupling member (211) provided at the lower end of the deck support member (210) has a wedge penetration hole (211-1) formed that penetrates from one side to the other, and the two sides of the deck beam yoke member (10) are fitted into the square coupling member (211) of the deck support member (210), and the lower end of the deck support member (210) is fixed to both sides of the deck beam yoke member (10) by inserting a deck wedge (213) from one side to the other through the wedge penetration hole (211-1).

[0036] The above deck wedge (213) is provided with a wedge body (213-1) that gradually widens from one side to the other, and the upper part of the wedge body (213-1) is provided to have a horizontal shape and the lower part to have an inclined shape so that it can be easily fitted.

[0038] A first inclined section (213-6) is provided on the lower side of the wedge body (213-1) equipped with the above-mentioned curved pressure section (213-5) in a shape that gradually narrows from one side toward the other side, and a second inclined section (213-7) having a gentle slope toward the above-mentioned catch groove (213-3) is provided at the end of the first inclined section (213-6) so that the wedge body (213-1) can move upward during the fitting process and sufficiently press the bottom surface of the deck beam yoke (10).

[0039] The lower portion of the male screw rod (220) is provided with a locking portion (223) that protrudes outward from the outer surface, so that when the lower portion of the male screw rod (220) provided with the locking portion (223) is inserted from the upper portion of the deck support (210), two rows of guide rings (212) are provided to be pressed against the upper portion of the deck support (210), thereby preventing the male screw rod (220) from being separated and detached from the deck support (210).

[0040] The two rows of guide rings (212) provided to be attached to the upper part of the deck support (210) are provided to be pressed inward from the outer surface, and thus have a shape that protrudes toward the center from the inner circumference of the deck support (210), so that the lower end of the male screw rod (220) is caught by the provided catch (223).

[0041] The joint reinforcement structure (A) of the above-mentioned deck plate can prevent various troubles from occurring, such as the side panel (SP) of the deck beam (DB) in the joint section (JT), which is the inner connection part of the deck slab (DS) and the deck beam (DB), becoming bulged on both sides and the deck slab (DS) in the joint section (JT) being crushed downwards, when concrete (C) is poured into the deck slab (DS) and deck beam (DB) of the deck plate (DP) and vibration compaction is performed during the construction of the reinforced concrete structure (RC), thereby preventing safety accidents caused by the collapse of the deck plate (DP) in the reinforced concrete structure (RC).
