Description

Technology Field

[0001] The present invention relates to a deep deck reinforcement system having a reinforcing assembly with an integrated support shoe, and more specifically, to a deep deck reinforcement system having a reinforcing assembly with an integrated support shoe that reinforces the ends of a deep deck mounted on both sides of a support beam such as a steel beam or a PC beam. Background Technology

[0002] In the prior art, Patent No. 10-1851824, registered by the present applicant, proposes a ‘continuous end deck plate system with end haunch type utilizing a cap plate’ (hereinafter referred to as the ‘prior art document’).

[0003] The technology disclosed in the prior art literature involves closing the ends of a deep deck with a bent cap plate and fastening a component combining this cap plate and reinforcing steel bars to the upper part of a supporting beam with multiple direct screws, thereby causing the deck to behave like a continuous beam. Through this, the effect of omitting the installation of shoring during long-span construction was partially achieved.

[0004] However, the technology disclosed in the prior art literature has the following limitations.

[0005] First, due to the structural characteristic of the cap plate completely covering the top of the deep deck, it is fundamentally impossible to install additional shear reinforcement to reinforce the shear strength of the slab, and this has the disadvantage of a fatal limitation in that the cap plate technology cannot be applied to structural designs where shear reinforcement is essential.

[0006] Second, since the cap plate has a cross-sectional shape formed with multiple steps, not only is the shape complex, but precise bending and punching processes are required due to the complex shape, which has the disadvantage of high production costs and reduced productivity.

[0007] Third, due to the complex cross-sectional shape of the cap plate, it can only be optimally applied to deep decks with specific corresponding shapes and dimensions, so it is not compatible with deep deck products with different rib shapes or heights, which has the disadvantage of having limited versatility.

[0009] Accordingly, the present invention was devised to solve the problems of the prior art as described above, and aims to provide a deep deck reinforcement system having a reinforcement assembly with an integrated support shoe, wherein a support shoe is integrally installed on the shear reinforcement of a reinforcement assembly composed of an upper reinforcement and a shear reinforcement, and the reinforcement assembly with the integrated support shoe is installed on both deep decks mounted on both sides of a support beam, thereby allowing the deep deck to behave like a continuous beam and enabling simple application to structural designs where shear reinforcement is essential.

[0010] Another objective of the present invention is to provide a deep deck reinforcement system having a reinforcement assembly with an integrated support shoe, which is universally applicable without restrictions on the type of deep deck or the shape of the support member, by having the support shoe integrally formed with the shear reinforcement.

[0011] Another objective of the present invention is to provide a deep deck reinforcement system having a reinforcement assembly with an integrated support shoe, wherein the upper reinforcement for negative moment reinforcement, the shear reinforcement, and the support shoe for deck fixing are provided as completely integrated, thereby minimizing on-site work and significantly improving constructability and quality uniformity. means of solving the problem

[0021] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings.

[0022] The terms used in this invention are defined considering their functions within the invention; however, since these may vary depending on the intentions or practices of the user or operator, the definitions of these terms should be interpreted in a meaning and concept consistent with the technical details of this invention.

[0023] In addition, the embodiments of the present invention are not intended to limit the scope of the rights of the present invention, but are merely exemplary matters of the components presented in the claims of the present invention, and are embodiments that include components that are included in the technical concept throughout the specification of the present invention and can be substituted as equivalents for the components of the claims.

[0024] Additionally, optional terms in the following examples are used to distinguish one component from another, and the components are not limited by said terms.

[0025] Accordingly, in describing the present invention, detailed descriptions of related prior art that may unnecessarily obscure the essence of the invention are omitted.

[0026] The attached drawings, FIGS. 1 to 7, are drawings illustrating a reinforcing bar assembly with an integrated support shoe according to the present invention and a deep deck reinforcing system to which the reinforcing bar assembly is applied.

[0027] As shown in FIGS. 1 to 4, the deep deck (100) according to the present invention is provided by being mounted on each side of a support beam (200), and the deep deck (100) on both sides mounted on the support beam (200) is reinforced by installing a reinforcing assembly (140) across the support beam (200) to connect the deep decks (100) on both sides.

[0028] In particular, the deep deck (100) in this embodiment is installed by being mounted on each side of a single support beam (200) made of a steel frame structure.

[0029] As shown in FIGS. 1 and 3, this deep deck (100), that is, a deep deck, includes an upper deck section (110) formed as a flat surface at regular intervals to prevent sagging and bending phenomena during concrete pouring, a beam deck section (120) that acts as a beam to support the load due to bending moment and provides strength to prevent sagging and bending phenomena during concrete pouring, and a reinforcement section to compensate for the weakness of the tensile stress of the concrete (C) after concrete pouring with a number of reinforcing bars.

[0030] The upper deck section (110) and the beam deck section (120) are preferably made of galvanized steel, and the thickness is preferably around 0.8 mm.

[0031] In addition, the reinforcing bar portion formed in the deep deck (100) is embedded in the concrete (C) poured over the multiple reinforcing bars, thereby not only reinforcing the concrete (C) and the deep deck (100) but also enabling the integrated behavior of the deep deck (100), the concrete (C), and the support beam (200).

[0032] In particular, the reinforcing bar section configured in the deep deck (100) as described above includes a plurality of upper reinforcing bars (131) (132) installed in a horizontal grid shape on the upper part of the deep deck (100) to reinforce the twisting and bending of the support beam (200), a lower reinforcing bar (not shown) installed on the inner lower part of the beam deck section (120) to reinforce the shear force of the support beam (200), and a reinforcing bar assembly (140) installed in a shape-matched manner on the upper surface of the deep deck (100) to reinforce the shear force of the deep deck (100).

[0033] Here, the lower reinforcing bar is a single straight reinforcing bar and can be installed in the longitudinal direction of the deep deck (100) in the groove (121) of the deep deck (100) to connect the deep decks (100) on both sides across the support beam (200) as well as the deep deck (100).

[0034] And, the reinforcing bar assembly (140) to be described later is provided with a lower reinforcing bar (150) parallel to the lower reinforcing bar, and the lower reinforcing bar (150) will be described in detail in the reinforcing bar assembly (140) to be described later.

[0035] Additionally, a plurality of upper reinforcing bars (131) (132) are installed in a grid shape on the upper portion spaced apart from the reinforcing bar assembly (140).

[0036] That is, among the plurality of upper reinforcing bars (131) (132), the first upper reinforcing bar (131) is installed by being arranged in the length direction of the deep deck (100) (left and right length direction of the deep deck (100) installed between the two support beams (200)), and the second upper reinforcing bar (132) is installed by being arranged perpendicular to the first upper reinforcing bar (131) at the bottom of the first upper reinforcing bar (131).

[0037] Additionally, the first upper reinforcing bar (131) is a single straight reinforcing bar and is provided across the upper part of the support beam (200) at the top of the deep deck (100) in parallel with the lower reinforcing bar (150) to be described later, just like the lower reinforcing bar (150).

[0038] Meanwhile, as shown in FIGS. 2 to 4, the reinforcing assembly (140) includes a shear reinforcing bar (142) having a protruding support member (142a) that is inserted and installed in the groove (121) of the deep deck (100), a bent support member (142b) that is formed by bending at both sides of the protruding support member (142a) and is installed by being seated on the upper deck portion (110) of the deep deck (100), and a suspension member (142c) that is formed by bending so as to protrude upward from the deep deck (100) between the two bent support members (142b) and the protruding support member (142a) and has an upper reinforcing bar (141) installed thereon.

[0039] Additionally, the reinforcing bar assembly (140) further includes a support shoe (160) that is integrally formed by penetrating and joining the protruding support portion (142a) of the shear reinforcing bar (142) and is seated and fixed to the upper deck portion (110) of the deep deck (100).

[0040] Thus, the two deep decks (100) mounted on both sides of the support beam (200) are connected by a reinforcing assembly (140) to reinforce the negative moment and shear force acting on the ends of the deep decks (100), and the support shoes (160) are each fixed to the upper deck portions (110) of the two deep decks (100), thereby firmly reinforcing and controlling the reinforcing assembly (140) so that it does not become separated from the deep decks (100) or move horizontally.

[0041] Meanwhile, a plurality of lower reinforcing bars (150) are arranged side by side within the protruding support portion (142a) of the shear reinforcing bar (142). The plurality of lower reinforcing bars (150) penetrate the interior of the protruding support portion (142a) and are arranged in an orthogonal manner, and are welded and fixed to the protruding support portion (142a).

[0042] These lower reinforcing bars (150) are multiple straight reinforcing bars and are installed to connect the deep decks (100) on both sides across the support beam (200) as shown in FIG. 3.

[0043] In addition, as shown in FIGS. 2 and 4, upper reinforcing bars (141) made of straight reinforcing bars are provided on the lower side of the suspension portions (142c) of the shear reinforcing bars (142).

[0044] These shear reinforcing bars (142) are formed by bending to correspond to a cross-sectional shape corresponding to the deep deck (100). That is, a protruding support portion (142a) corresponding to the groove (121) of the deep deck (100) is formed protruding downward in the central part of the shear reinforcing bar (142), and a bent support portion (142b) is formed on both sides of the protruding support portion (142a) that is extended outward and bent to have a shape corresponding to the upper deck portion (110) of the deep deck (100).

[0045] Additionally, between the protruding support portion (142a) and the suspension portion (142c), an inner connecting portion (142d) is formed with a slope that gradually widens outward from the protruding support portion (142a) to the suspension portion (142c) to connect the protruding support portion (142a) and the suspension portion (142c), and between the suspension portion (142c) and the bending support portion (142b), an outer connecting portion (142e) is formed with a slope that gradually widens outward from the suspension portion (142c) to the bending support portion (142b) to connect the suspension portion (142c) and the bending support portion (142b).

[0046] In particular, the upper reinforcing bar (141) is welded and fixed in an orthogonal manner to the lower side of both suspension sections (142c) of the shear reinforcing bar (142), so that the upper reinforcing bar (141) is integrally formed on both suspension sections (142c) of the shear reinforcing bar (142).

[0047] Accordingly, the protruding support portion (142a) and the two bent support portions (142b) of the shear reinforcing bar (142) constituting the reinforcing bar assembly (140) are respectively installed by being fixedly coupled to the groove portion (121) and the upper deck portion (110) of the deep deck (100) in a shape-matched manner.

[0048] In particular, it is preferable that the reinforcing assembly (140) as described above be formed with a length (0.25 to 0.3 L) of 25 to 30 percent of the length (L) of the single deep deck (100) connecting the two support beams (200).

[0049] In addition, among the reinforcing bar assembly (140), the shear reinforcing bar (142) is installed by being arranged from the end of the deep deck (100) toward the center, and the upper reinforcing bar (141) is installed across the support beam (200) between the two deep decks (100) to connect the deep decks (100) on both sides.

[0050] Thus, the reinforcing assembly (140) can firmly reinforce the negative moment and shear force acting on the end of the deep deck (100) by means of the shear reinforcing bar (142) and the upper reinforcing bar (141) integrated with the shear reinforcing bar (142).

[0051] Meanwhile, the support shoe (160) is formed in a rectangular shape like a fedora, as shown in FIGS. 5 to 7.

[0052] Specifically, the support shoe (160) is provided on the upper surface of the deep deck (100) perpendicular to the longitudinal direction of the deep deck (100) (i.e., the direction of the groove (121) of the deep deck (100)) and includes a cover portion (161) that covers across the groove (121) of the deep deck (100), a connecting portion (163) that is formed extending outward from the lower end of the cover portion (161) and is fixed in a seated state on the upper surface of the deep deck (100), and a narrowing portion (161b) formed on the upper surface of the cover portion (161) through which the protruding support portion (142a) of the shear reinforcing bar (142) is connected.

[0053] Here, the cover portion (161) is formed in a trapezoidal shape having a diameter that gradually narrows as it goes from the bottom to the top, as shown in FIG. 5. This cover portion (161) is provided by being seated on both upper deck portions (110) while crossing the groove (121) of the deep deck (100).

[0054] And, a groove (161a) is formed along the length direction, that is, the long direction, in the central part of the upper surface of the cover part (161), and a narrow hole (161b) that penetrates to a certain length is formed in the groove (161a).

[0055] In particular, the narrow section (161b) is formed to have a length smaller than the upper width (outer diameter) of the inner connecting section (142d) connecting the protruding support section (142a) and the suspension section (142c) of the shear reinforcing bar (142).

[0056] Accordingly, the inner connecting portion (142d) of the shear reinforcing bar (142) is fitted into the clamping portion (161b) as shown in FIG. 7 and, as the inner connecting portion (142d) is inserted deeply into the clamping portion (161b) up to the upper part, the outer diameter of the inner connecting portion (142d) is elastically compressed and reduced as it is fitted, so that the protruding support portion (142a) of the shear reinforcing bar (142) protrudes downward from the support shoe (160) and the suspension portion (142c) protrudes upward from the support shoe (160), thereby firmly maintaining the state.

[0057] In addition, the shear reinforcement (142) can adjust the width between the two suspension sections (142c) according to the length of the narrow section (161b), thus providing versatility so that the reinforcement assembly (140) can be easily installed on all deep decks (100).

[0058] And, the support shoe (160) has a side slope surface (162) formed on both sides in the longitudinal direction with a slope corresponding to the slope of the outer connecting part (142e) connecting the suspension part (142c) and the bending support part (142b) of the shear reinforcing bar (142), and a stepped part (162a) is formed in the center of the side slope surface (162) as shown in FIGS. 5 and 6.

[0059] As shown in FIG. 7, the outer connecting portion (142e) of the shear reinforcing bar (142) is fitted and connected to both stepped portions (162a) of the side slope (162), thereby allowing the support shoe (160) and the shear reinforcing bar (142) to be fixed in the correct position.

[0060] In addition, an upper reinforcing bar (141) is installed in the suspension portion (142c) protruding above the cover portion (161) of the support shoe (160). The upper reinforcing bar (141) passes through and crosses between the suspension portion (142c) of the shear reinforcing bar (142) and the cover portion (161) of the support shoe (160), and is welded and fixed to the lower side of the suspension portion (142c) and the upper surface of the cover portion (161) where the upper reinforcing bar (141) contacts, respectively, thereby allowing the support shoe (160), the shear reinforcing bar (142), and the upper reinforcing bar (141) to be formed as a single unit.

[0061] Thus, the upper reinforcing bar (141) is supported in contact with the upper surface of the cover portion (161) of the support shoe (160), and the shear reinforcing bar (142) is suspended through the suspension portion (142c).

[0062] In particular, the support shoe (160) as described above is installed at regular intervals on a plurality of shear reinforcing bars (142) suspended by upper reinforcing bars (141), thereby forming a reinforcing bar assembly (140) in which the shear reinforcing bars (142), upper reinforcing bars (141), and support shoe (160) are integrated into a single module.

[0063] In the process of manufacturing, the shear reinforcing bar assembly (140) is supplied to the site with the shear reinforcing bar (142), the upper reinforcing bar (141), and the support shoe (160) integrated. The upper reinforcing bar (141) is inserted through each of the suspension portions (142c) of the shear reinforcing bar (142) and is integrated by welding and fixing the contact portion between the suspension portion (142c) of the shear reinforcing bar (142) and the upper reinforcing bar (141). Then, the clamping portion (161b) of the support shoe (160) is fitted into the inner connecting portion (142d) of the shear reinforcing bar (142), and the contact portion between the cover portion (161) of the support shoe (160) and the upper reinforcing bar (141) is welded and fixed, thereby integrating the reinforcing bar assembly (140).

[0064] And, the connecting part (163) is a plate bent outward from the lower part of the cover part (161), and is provided to be fixedly connected to the upper deck part (110) through a direct screw (not shown) while in a state of being seated in surface contact with the upper deck part (110) of the deep deck (100).

[0065] The reinforcing bar assembly (140) according to the present invention as described above is supplied to the site as a single integrated module in which the shear reinforcing bar (142), the upper reinforcing bar (141), and the support shoe (160) are mutually combined and fixed during the manufacturing process.

[0066] The reinforcing bar assembly (140) supplied in this manner is installed on the deep deck (100) mounted on both sides of the support beam (200), wherein the protruding support portion (142a) in the center of the shear reinforcing bar (142) is inserted into the groove (121) of the deep deck (100) and the bent support portions (142b) on both sides are seated on the upper deck portions (110) of the deep deck (100) and are reinforced.

[0067] In this process, the connecting portion (163) of the support shoe (160) integrated with the reinforcing bar assembly (140) is placed on both upper deck portions (110) while covering the groove (121) of the deep deck (100), and in this state, the connecting portion (163) of the support shoe (160) is fastened and fixed to the upper deck portions (110) of the deep deck (100) with a direct screw.

[0068] Afterwards, the installation of the reinforcing assembly (140) is completed by welding and fixing a plurality of lower reinforcing bars (150) to the protruding support portion (142a) of the shear reinforcing bar (142) arranged in the groove (121) of the deep deck (100).

[0069] In particular, the lower reinforcing bar (150) arranged as described above is installed to extend across the support beam (200) to the deep deck (100) on the opposite side, thereby reinforcing the negative moment and shear force acting on the end of the deep deck (100).

[0070] In addition, the shear reinforcement (142) and the support shoe (160) of the reinforcement assembly (140) are installed at the end of the deep deck (100), and are installed from the end of the deep deck (100) mounted on the support beam (200) toward the center side with a length (0.25 to 0.3 L) of 25 to 30 percent of the length (L) of the deep deck (100).

[0071] Thus, the shear reinforcement (142) installed at the end of the deep deck (100) reinforces the negative moment and shear force acting on the end of the deep deck (100) together with the lower reinforcement (150), and the support shoe (160) is fixed to the upper deck portion (110) of the deep deck (100) with a direct screw, thereby controlling the reinforcement assembly (140) so that it does not become separated from or move horizontally away from the deep deck (100).

[0072] Afterwards, a separate lower reinforcing bar (not shown) is installed in parallel with the lower reinforcing bar (150) on the lower side of the protruding support portion (142a) of the shear reinforcing bar (142), and a plurality of upper reinforcing bars (131) (132) are installed in a grid shape on the upper side of the reinforcing bar assembly (140).

[0073] At this time, among the plurality of upper reinforcing bars (131) (132), the first upper reinforcing bar (131) is installed by being arranged in the longitudinal direction of the deep deck (100), and the second upper reinforcing bar (132) is installed by being arranged perpendicular to the first upper reinforcing bar (131) at the lower part of the first upper reinforcing bar (131).

[0074] These first upper reinforcing bars (131) are installed parallel to the lower reinforcing bars (150) while crossing the support beam (200) just like the lower reinforcing bars (150), thereby reinforcing the negative moment and shear force acting on the end of the deep deck (100).

[0075] Accordingly, in the present invention, when constructing a reinforcing assembly (140) on a deep deck (100), the shear reinforcing bar (142), the upper reinforcing bar (141), and the support shoe (160) are integrated into a single module, thereby unifying the construction process of the upper reinforcing bar (141) and the shear reinforcing bar (142), which is the most difficult and cumbersome, and reducing the process, it is possible to shorten the construction time and improve the constructability.

[0076] And, since the reinforcing bar assembly (140) is supplied to the site as a single module and placed on the upper deck portion (110) of the deep deck (100), and the construction is completed by only the process of fastening the connecting portion (163) of the shear reinforcing bar (142) to the upper deck portion (110) of the deep deck (100) with a direct screw, the error due to the skill level of the site workers can be reduced and the construction period can be drastically shortened.

[0077] In addition, when concrete is poured on the deep deck (100) on which the reinforcing assembly (140) is installed, the reinforcing assembly (140) is fixed in a semi-rigid state by the strong bonding force of the support shoe (160) which is fastened and fixed to the upper deck portion (110) of the deep deck (100) with a direct screw, and the resistance performance of the negative moment at the end of the deep deck (100) due to the construction load is improved, so that the deflection and positive moment of the central part of the deep deck (100) can be effectively reduced.

[0078] In addition, after the poured concrete (C) hardens, the upper reinforcing bar (141) acts as a permanent negative moment tensile reinforcing bar of the slab, and the shear reinforcing bar (142) acts as a stirrup that resists shear force, so that both the negative moment and shear force can be reinforced simultaneously.

[0079] Although the present invention has been described in detail through specific embodiments, this is for the purpose of specifically explaining the invention, and the invention is not limited thereto. It is evident that modifications or improvements can be made by those skilled in the art within the technical scope of the invention.

[0080] All simple variations or modifications of the present invention fall within the scope of the present invention, and the specific scope of protection of the present invention will be clarified by the appended claims. Explanation of the symbols
