Description

Technical Field

[0001] This invention relates to a beam reinforcement structure and a method for constructing a reinforcement system therein. Specifically, this invention relates to a beam reinforcement structure comprising stirrups with extended portions and a method for constructing a reinforcement system therein. Prior Technology

[0002] In the construction industry, the core framework of a building widely utilizes reinforced concrete systems for support, thereby enhancing the strength and stability of the structure. As mentioned above, in practice, the framework of a reinforced concrete system typically needs to strike a balance between stability and ease of construction. Furthermore, in conventional reinforced concrete systems, the number and density of tied and positioned reinforcing bars increase as the project progresses. Therefore, installing any new reinforcing bars from a previously tied and positioned framework presents a challenge. In particular, long, extended reinforcing bars, such as main beam reinforcement, often need to pass through many gaps in the existing framework and may require bending or insertion at specific angles. As stated above, the complexity of these frameworks, along with the weight and length of the reinforcing bars, often increases the difficulty and complexity of these operations, making the structural engineering extremely labor-intensive and time-consuming, and often requiring highly experienced construction workers.

[0003] Furthermore, in addition to the issues mentioned above, conflicts between the reinforcement system and other planned structures frequently become problems during construction. Poorly designed reinforcement structures may unexpectedly protrude or become visible from the building structure. This can degrade the appearance of the completed building structure and may compromise the integrity and reliability of the overall structure. Therefore, there is a need to develop reinforcement structures and corresponding construction procedures that offer the expected stability and reliability while facilitating construction and minimizing interference with other planned structures. Summary of the Invention

A steel cage composed of a plurality of outer stirrups, such that the pairs of extended portions of each of the outer stirrups are respectively supported on the first auxiliary bars and the second auxiliary bars to form a beam reinforcement base skeleton corresponding to the joint section extending from the column module along the beam extension direction; the inner stirrup framework step, wherein a plurality of inner stirrups are arranged one by one along the beam extension direction or a steel cage composed of a plurality of inner stirrups is arranged such that the inner stirrups are correspondingly arranged in the outer stirrup openings of the outer stirrups; and the beam lower main reinforcement framework step, wherein a plurality of beam lower main reinforcements are arranged one by one through the outer stirrup openings and the joint section or a beam lower main reinforcement module formed by the arrangement of a plurality of beam lower main reinforcements is arranged such that the beam lower main reinforcements or the beam lower main reinforcement module are supported by the lower confinement section and the beam reinforcement base skeleton.

[0019] Various embodiments will be described below, and those skilled in the art should readily understand the spirit and principles of the invention by referring to the description and accompanying drawings. However, while specific embodiments will be described in detail herein, these embodiments are merely illustrative and are not intended to be limiting or exhaustive in any respect. Therefore, various changes and modifications to the invention will be readily apparent and easily achievable by those skilled in the art without departing from the spirit and principles of the invention.

[0020] Referring to Figures 1 and 2, according to one embodiment of the present invention, a beam reinforcement structure 10 along a intended beam extension direction DB is provided, comprising at least one beam reinforcement frame BF. Each of the beam reinforcement frames BF includes at least: an outer stirrup 100 defining the foundation skeleton; an inner stirrup 200 disposed within the outer stirrup 100 to enhance stability; and a stirrup cap assembly 400 for sealing or covering the outer stirrup 100.

[0021] As described above, according to this embodiment, the outer stirrup 100 may have a bottom section 105 for supporting the lower layer of main reinforcement V of the beam, a pair of upright sections 110 and 120 respectively connected to both ends of the bottom section 105, and a pair of horizontally extending sections 130 and 140 respectively extending laterally from the top of the pair of upright sections 110 and 120. The bottom section 105 of the outer stirrup 100 and the pair of upright sections 110 and 120 together define an outer stirrup opening OP1 for defining or limiting the scope of other reinforcing steel components and enclosing the subsequently grouted concrete. As described above, the inner stirrup 200 is disposed in the outer stirrup opening OP1 and positioned based on the outer stirrup 100.

[0022] Specifically, according to this embodiment, as shown in Figures 1 and 2, the inner stirrup 200 disposed in the outer stirrup opening OP1 may have a first vertical bar 210 and a second vertical bar 220, and a bottom intermediate section 205 extending laterally between the first vertical bar 210 and the second vertical bar 220. Similar to the outer stirrup 100, the inner stirrup 200 may be U-shaped, defining the inner stirrup opening OP2 facing away from the bottom section 105. Furthermore, according to this embodiment, to enhance positioning stability, the bottom intermediate section 205 may overlap with the bottom section 105 of the outer stirrup 100. For example, the bottom intermediate section 205 may overlap with the bottom section 105 side-by-side along the beam extension direction DB, but is not limited thereto. In addition, the first vertical bar 210 and the second vertical bar 220 of the inner stirrup 200 can be further lapped with other steel reinforcement components, thereby further strengthening the stability and reliability of the overall beam steel reinforcement structure 10, and these details will be further illustrated in detail in the various forms below.

[0023] Referring again to Figures 1 and 2, the beam reinforcement frame 10 according to this embodiment may further include a first auxiliary reinforcement bar FT1 and a second auxiliary reinforcement bar FT2 extending parallel to the beam extension direction DB of the beam reinforcement frame 10. As described above, the pair of extended portions 130 and 140 of the outer stirrups 100 can be supported by the first auxiliary reinforcement bar FT1 and the second auxiliary reinforcement bar FT2 respectively, such that the first auxiliary reinforcement bar FT1 is positioned within the space of the angle θ1 between the corresponding extended portion 130 and the upright portion 110, while the second auxiliary reinforcement bar FT2 is positioned within the space of the angle θ2 between the corresponding extended portion 140 and the upright portion 120. Therefore, the extended portions 130 and 140 can be supported by the first auxiliary reinforcement bar FT1 and the second auxiliary reinforcement bar FT2, thereby positioning and supporting the entire beam reinforcement frame BF.

[0024] In detail, according to some embodiments, based on considerations such as operational tolerances and practical operation, the included angle θ1 between the corresponding horizontal portion 130 and the vertical portion 110, and the included angle θ2 between the corresponding horizontal portion 140 and the vertical portion 120, can be substantially between 80 degrees and 100 degrees. For example, the included angle θ1 between the corresponding horizontal portion 130 and the vertical portion 110, and the included angle θ2 between the corresponding horizontal portion 140 and the vertical portion 120, can be substantially 90 degrees. As mentioned above, except for the bend at the connection, the general extension direction of the horizontal portion 130 or 140 can be substantially perpendicular or approximately perpendicular to the extension direction of the vertical portion 110 or 120. In other words, the horizontal portions 130 and 140 can extend substantially laterally, such that the free ends Q1 and Q2 of the pair of horizontal portions 130 and 140 are positioned outside the outer stirrup opening OP1.

[0025] As described above, according to this embodiment, the arrangement of the outer stirrups 100 and inner stirrups 200 helps to define the outline of the beam reinforcement structure 10 and helps to limit other reinforcement components. Furthermore, according to this embodiment, referring to Figures 1 and 2, various types of stirrup cap assemblies 400 can be configured to cover the top of the outer stirrup opening OP1, thereby sealing or enclosing the outer stirrup 100 and completing the beam reinforcement structure 10 of this embodiment, which has excellent workability and structural strength.

[0026] For example, as shown in Figures 1 and 2, a stirrup cap assembly 400 according to an embodiment of the present invention includes: a first stirrup cap 410 covering a portion of the outer stirrup opening OP1 facing the upright portion 110, and a second stirrup cap 420 covering a portion of the outer stirrup opening OP1 facing the upright portion 120. Specifically, according to this embodiment, the stirrup cap assembly 400 may not be a single integrally formed stirrup cap spanning the entire outer stirrup opening OP1 to the second auxiliary reinforcement FT2 from the first auxiliary reinforcement FT1, but rather has two independent stirrup caps, thereby respectively covering the top of the intermediate section from the first auxiliary reinforcement FT1 to the outer stirrup opening OP1 and the top of the intermediate section from the second auxiliary reinforcement FT2 to the outer stirrup opening OP1. Continuing from the above, according to some embodiments, at the top of the outer stirrup opening OP1, the first stirrup cap 410 and the second stirrup cap 420 may have at least a portion of their sections overlapping in a direction perpendicular to the beam extension direction DB. Furthermore, the overlapping sections of the first stirrup cap 410 and the second stirrup cap 420 can overlap each other. For example, according to this embodiment, the sections of the first stirrup cap 410 and the second stirrup cap 420 that overlap at the top of the inner stirrup opening OP2 and the top of the outer stirrup opening OP1 can overlap each other, thereby integrating the independent first stirrup cap 410 and the second stirrup cap 420 into a complete stirrup cap assembly 400 spanning the outer stirrup opening OP1. It should be noted that the overlapping sections of the first stirrup cap 410 and the second stirrup cap 420 specifically illustrated herein are merely examples, and the overlapping pattern or range of the two is not limited to the range corresponding to the top of the inner stirrup opening OP2. Furthermore, in some embodiments, the stirrup cap assembly 400 may also be further overlapped with other steel reinforcement components, thereby strengthening and improving the stability and reliability of the overall beam reinforcement structure 10, and these details will be further described in detail in the various embodiments below.

[0027] As described above, according to some embodiments, the first stirrup cap 410 may have a first covering section R1, and a first hook portion G1 and a first hanging portion N1 respectively connected to the opposite ends of the first covering section R1. Similarly, the second stirrup cap 420 may have a second covering section R2, and a second hook portion G2 and a second hanging portion N2 respectively connected to the opposite ends of the second covering section R2. The first hook portion G1 may extend at least partially beyond the outer stirrup opening OP1 and be hung on the first auxiliary reinforcement FT1, and the first hook portion G1 may bend around the first auxiliary reinforcement FT1 so that the free end P1 of the first hook portion G1 points towards the outer stirrup opening OP1. Likewise, the second hook portion G2 may extend at least partially beyond the outer stirrup opening OP1 and be hung on the second auxiliary reinforcement FT2, and the second hook portion G2 may bend around the second auxiliary reinforcement FT2 so that the free end P2 of the second hook portion G2 points towards the outer stirrup opening OP1. Based on this architecture, the construction worker can more easily and securely hang the first stirrup cap 410 and the second stirrup cap 420 on the top of the outer stirrup opening OP1, thereby completing the construction of the stirrup cap assembly 400.

[0028] As described above, referring to Figures 1 and 2, the first stirrup cap 410 and the second stirrup cap 420 can each partially cover a portion of the outer stirrup opening OP1 and, for example, span across a plurality of upper main beam reinforcements T and rest on a plurality of upper main beam reinforcements T, respectively, and bend and turn around the first auxiliary reinforcement FT1 and the second auxiliary reinforcement FT2. Therefore, the first auxiliary reinforcement FT1 can be substantially surrounded and even at least partially closed by the first hook portion G1 of the first stirrup cap 410, and the second auxiliary reinforcement FT2 can be substantially surrounded and even at least partially closed by the second hook portion G2 of the second stirrup cap 420. For example, according to some embodiments, the free ends P1 of the first hook portion G1 and P2 of the second hook portion G2 can even extend beyond the upright portions 110 and 120 and into the outer stirrup opening OP1. Therefore, according to this embodiment, the strength, positioning and stability of the beam steel reinforcement structure 10 tightly fastened by the overall stirrup cap assembly 400 can be enhanced, and the confinement effect of subsequent grouting concrete can be further provided.

[0029] Furthermore, according to this embodiment, the first hanging portion N1 of the first stirrup cap 410, opposite to the first hook portion G1, can extend directly into the outer stirrup opening OP1 from the top towards the bottom portion 105, while the second hanging portion N2 of the second stirrup cap 420, opposite to the second hook portion G2, can extend directly into the outer stirrup opening OP1 from the top towards the bottom portion 105. As described above, the first hanging portion N1 and the second hanging portion N2 correspond to the outer stirrup opening OP1, respectively extending vertically into the outer stirrup opening OP1 from opposite sides towards the upright portion 120 and the upright portion 110. In this regard, please refer to Figure 3 (unassembled state) and Figure 4 (assembled state), which only show the simplified configuration of the outer stirrup 100, inner stirrup 200, first stirrup cap 410, and second stirrup cap 420. It can be seen that the first hanging part N1 can substantially correspond to the second vertical bar 220, and the second hanging part N2 can substantially correspond to the first vertical bar 210.

[0030] Referring to Figures 1 to 4, according to this embodiment, the correspondingly arranged first hanging portion N1 and second vertical reinforcement 220 may be spaced apart in the extending direction of the vertical portions 110 and 120, while the correspondingly arranged second hanging portion N2 and first vertical reinforcement 210 may be spaced apart in the extending direction of the vertical portions 110 and 120. Therefore, the beam reinforcement frame BF according to this embodiment may further include reverse inner stirrups 200'. In detail, the reverse inner stirrups 200' may have a first reverse vertical reinforcement 210' and a second reverse vertical reinforcement 220', and a top intermediate section 205' connecting the first reverse vertical reinforcement 210' and the second reverse vertical reinforcement 220' and extending laterally. The reverse inner stirrups 200' may be U-shaped and define a reverse inner stirrup opening OP2' that opens towards the bottom section 105. As described above, according to this embodiment, the inner stirrup opening OP2 and the reverse inner stirrup opening OP2' can face each other, and the first reverse vertical bar 210' of the reverse inner stirrup 200' can overlap with the first vertical bar 210 of the inner stirrup 200, while the second reverse vertical bar 220' of the reverse inner stirrup 200' can overlap with the second vertical bar 220 of the inner stirrup 200. Furthermore, the top intermediate section 205' of the reverse inner stirrup 200' can also overlap with at least a portion of the first stirrup cap 410 and the second stirrup cap 420, such as the overlapping section of the two. Therefore, even though the first hanging part N1 and the second vertical bar 220 are spaced apart in the extension direction of the vertical parts 110 and 120 according to this embodiment, and the second hanging part N2 and the first vertical bar 210 are spaced apart in the extension direction of the vertical parts 110 and 120, the upper part and the lower part of the beam steel reinforcement frame 10 can still be connected and closed, thereby assembling the beam steel reinforcement frame 10 more stably, and relatively sealing the outer stirrups 100 and inner stirrups 200 and the various beam main bars (such as the upper beam main bar T and the lower beam main bar V) supported thereon.

[0031] As described above, a comparison of the detailed front and perspective views of the exemplary beam reinforcement structure 10 constructed with reference to Figures 1 to 4 is shown in Figure 5. Based on the intermediate lap of the reverse inner stirrups 200', the first stirrup cap 410 and the second stirrup cap 420 covering the upper main reinforcement T of the beam can be indirectly connected to the lower inner stirrup 200 to form a closed structure. Therefore, according to this embodiment, the stability and reliability of the overlapping closure of the overall beam reinforcement structure 10 can be ensured by extending laterally outwards from the stirrup openings OP1 on both sides of the horizontally extended portions 130 and 140, and a reinforcing confinement effect can be provided for subsequent grouting concrete.

[0032] The above description details the beam reinforcement structure 10 according to one embodiment of the present invention. Those skilled in the art should understand that other variations in detail may be made to conform to the spirit of the invention. For example, referring to FIG6, another embodiment of the beam reinforcement structure 20 according to the present invention differs from the beam reinforcement structure 10 in that the correspondingly provided first hanging portion N1 and second vertical reinforcement 220 are not separated in the extension direction of the vertical portions 110 and 120, and the correspondingly provided second hanging portion N2 and first vertical reinforcement 210 are not separated in the extension direction of the vertical portions 110 and 120. Therefore, according to the configuration shown in FIG6, a closed connection structure can be completed without or selectively with reverse inner stirrups 200'.

[0033] In detail, as shown in Figure 6, the first vertical bar 210 and the second vertical bar 220 of the inner stirrup 200 can protrude to the height of the overlapping section of the first stirrup cap 410 and the second stirrup cap 420, opposite to the bottom section 105. Therefore, in essence, the first vertical bar 210 of the inner stirrup 200 can overlap with the second hanging portion N2 of the second stirrup cap 420, and the second vertical bar 220 of the inner stirrup 200 can overlap with the first hanging portion N1 of the first stirrup cap 410. Furthermore, according to this embodiment, the top ends of the first vertical bar 210 and the second vertical bar 220 can also have a first hook F1 and a second hook F2, respectively. Specifically, the beam reinforcement frame 20 may further include a plurality of upper beam main reinforcement bars T, which are provided corresponding to the top of the outer stirrup opening OP1 and extend through the beam reinforcement frame BF, and the first hook F1 and the second hook F2 can be respectively hung on at least one of the upper beam main reinforcement bars T. Therefore, according to this embodiment, the stability and reliability of the overlapping closure of the overall beam reinforcement frame 20 can be ensured under the reverse inner stirrups 200' that extend laterally to both sides of the outer stirrup opening OP1 in the horizontal extension portions 130 and 140 without intermediate connections, and can provide a reinforcing and confinement effect for subsequent grouting concrete.

[0034] Furthermore, referring to FIG7, in another embodiment of the beam reinforcement structure 30 according to the present invention, the entire structure can be connected and closed without intermediate reverse inner stirrups 200' when the first vertical bar 210 and the second vertical bar 220 of the inner stirrups 200 are relatively short. Specifically, the similarity between this embodiment and the beam reinforcement structure 20 described above is that the correspondingly provided first hanging portion N1 and second vertical bar 220 are not separated in the extension direction of the vertical portions 110 and 120, and the correspondingly provided second hanging portion N2 and first vertical bar 210 are not separated in the extension direction of the vertical portions 110 and 120. However, the difference between this embodiment and the beam reinforcement structure 20 described above is that although the first vertical bar 210 and the second vertical bar 220 protrude away from the bottom portion 105, they do not reach the setting height of the overlapping section of the first stirrup cap 410 and the second stirrup cap 420. That is, based on the bottom section 105, the height of the first vertical rib 210 and the second vertical rib 220 is lower than the height of the overlapping section of the first stirrup cap 410 and the second stirrup cap 420. Corresponding to the lowered first vertical rib 210 and the second vertical rib 220, according to this embodiment, the first hanging portion N1 and the second hanging portion N2 can extend deeper into the bottom section 105 and enter the outer stirrup opening OP1. Therefore, the first vertical rib 210 and the second vertical rib 220 protruding away from the bottom section 105 can still overlap with the second hanging portion N2 and the first hanging portion N1 respectively in the extending direction of the upright portions 110 and 120. As mentioned above, according to this embodiment, by overlapping in the extending direction of the upright portions 110 and 120, the first vertical rib 210 can overlap with the second hanging portion N2, and the second vertical rib 220 can overlap with the first hanging portion N1. Therefore, according to this embodiment, under the reverse inner stirrups 200' extending laterally outward from the stirrup openings OP1 in the horizontally extended portions 130 and 140 without an intermediary, the stability and reliability of the overlapping closure of the overall beam reinforcement structure 30 can be ensured, and the reinforcement and confinement effect of subsequent grouting concrete can be provided.

[0035] Next, the application of beam reinforcement structures according to some embodiments of the present invention will be further described with reference to Figures 8 and 9, wherein details or components unrelated to the description of the embodiments will be omitted in the figures to make the figures concise and clear.

[0036] Continuing from the above, according to some embodiments of the present invention, as shown in FIG8, beam reinforcement structures 40, which are the same as or similar to any of the beam reinforcement structures 10, 20, 30 shown in FIG1 to FIG7, can be used in conjunction with floor slab structures FL to construct beams. Wherein, when the beam reinforcement structure 40 is configured in conjunction with a floor slab structure FL, the pair of horizontally extending portions 130, 140 of the outer stirrups 100 can extend laterally into the floor slab structure FL. Continuing from the above, according to this embodiment, even if the thickness TH of the floor slab structure FL in the extending direction of the vertical portions 110, 120 is less than or equal to the length L1, L2 of either of the pair of horizontally extending portions 130, 140 extending laterally from the outer edge of the vertical portions 110, 120. In this embodiment, the two horizontally extending portions 130 and 140 extend laterally in a generally horizontal manner, thus allowing them to be laterally accommodated within the floor slab structure FL. Therefore, they do not bend or extend significantly at an angle or vertically, thereby not protruding or protruding from the floor slab structure FL. Consequently, this embodiment ensures that the beam reinforcement structure 40 and the floor slab structure FL will not interfere or conflict, thereby preventing potential damage to the finished appearance or even the structural stability and reliability.

[0037] Furthermore, according to this embodiment, concrete is poured onto the beam reinforcement frame 40 to form a protective layer PL from the surface of the reinforcement bars to the surface of the concrete. Referring to FIG8, the expected widths W1 and W2 of the protective layer PL, which extends laterally outward from the outer edges of the upright portions 110 and 120 to protect the beam reinforcement frame 40, can be less than the lengths L1 and L2 of either of the two horizontally extending portions 130 and 140 extending laterally from the outer edges of the upright portions 110 and 120. In other words, since, according to this embodiment, the two horizontally extending portions 130 and 140 extend laterally in a generally horizontal manner, they can be laterally accommodated in the floor slab frame FL without protruding or being visible, and the range of the two horizontally extending portions 130 and 140 extending laterally from the outer edges of the upright portions 110 and 120 may not be included within the range of the protective layer PL. Therefore, according to this embodiment, the thickness of the protective layer PL required to protect the two horizontally extending portions 130 and 140 can be reduced or avoided.

[0038] As described above, as shown in Figure 8, according to this embodiment, it is not necessary to provide a corresponding protective layer PL or a thickened floor slab structure FL to protect the two extended portions 130 and 140. Therefore, according to this application, the volume of the protective layer PL and the floor slab structure FL can be reduced, thereby reducing the material used for the protective layer PL and the floor slab structure FL and reducing or avoiding the space occupied by the building structure including the protective layer PL and the floor slab structure FL. In view of this, in addition to reducing construction costs and facilitating construction, the beam reinforcement structure 40 according to this embodiment can further improve the spaciousness of the space next to the building structure and the integrity and aesthetics of the building structure's appearance.

[0039] Next, referring to FIG9, in another embodiment of the present invention, construction can be carried out based on the design of the beam reinforcement structure 50 of the beam reinforcement structures 10, 20, 30, and 40 shown in FIG1 to FIG8, which is the same as or similar to the designs described above. Continuing, since the pair of horizontally extending portions 130 and 140 of the outer stirrups 100 can extend laterally to both sides, approximately perpendicular or nearly perpendicular to the vertical portions 110 and 120, the outer stirrup opening OP1 can remain uninterrupted by the pair of horizontally extending portions 130 and 140. Therefore, when the construction process progresses to the point where beam main reinforcement, such as, but not limited to, upper beam main reinforcement T or lower beam main reinforcement V, needs to be installed, it is more convenient to insert the beam main reinforcement, such as, but not limited to, upper beam main reinforcement T or lower beam main reinforcement V, through the outer stirrup opening OP1. Furthermore, multiple upper beam main reinforcement Ts or lower beam main reinforcement Vs can also be simultaneously suspended and inserted into the outer stirrup opening OP1. As shown in Figure 9, according to this embodiment, the construction process of setting the main reinforcement of the beam can be simplified, and the efficiency and yield of setting the main reinforcement of the beam can be further improved.

[0040] Next, a method for constructing a steel reinforcement system 1000 including a beam reinforcement structure 60 according to an embodiment of the present invention will be described with reference to Figures 10 to 17. In these figures, the auxiliary formwork K on one side is not shown so that the internal beam reinforcement structure 60 can be clearly displayed. Furthermore, according to this embodiment, the method will be described using a beam reinforcement structure 60 that is the same as or similar to the beam reinforcement structure 10 described above as an example.

[0041] Continuing from the above, referring to Figure 10, the structural method may first include, for example, the column module structural step S10: arranging a plurality of main column reinforcement bars C in mutually perpendicular first directions D1 and second directions D2 to construct the column module CM. These main column reinforcement bars C extend along a third direction D3 perpendicular to the first direction D1 and the second direction D2, and the column module CM can be divided along the third direction D3 into a lower confinement section LS and a joint section JS. Continuing from the above, the lower confinement section LS may be configured with at least one stirrup E1 and at least one tie bar E2 to confine the main column reinforcement bars C. Then, continuing to refer to Figure 10, the auxiliary reinforcement setting step S20 can be implemented: based on, for example, the first direction D1 as the beam extension direction DB, corresponding to the joint section JS, a first auxiliary reinforcement bar FT1 and a second auxiliary reinforcement bar FT2 are set parallel to the beam extension direction DB, extending in the opposite direction to the top of the lower confinement section LS. Continuing from the above, unlike typical beam reinforcement bars which must pass through the column formwork CM, in this embodiment, to avoid affecting the subsequent installation of stirrups at the beam-column joints of the column formwork CM, the first auxiliary reinforcement bar FT1 and the second auxiliary reinforcement bar FT2 are not installed through the column formwork CM in this auxiliary reinforcement installation step S20. The first auxiliary reinforcement bar FT1 and the second auxiliary reinforcement bar FT2 can be positioned based on the auxiliary template K and / or the column main reinforcement bar C on the side surface of the column formwork CM by means of leaning, binding, or welding. They can also be selectively further strengthened in subsequent works based on connecting components or by further connecting them through the column formwork CM. As mentioned above, the first auxiliary reinforcement bar FT1 and the second auxiliary reinforcement bar FT2 are used as auxiliary components for subsequent structures and may selectively have similar or weaker structural strength compared to the main structural components, but are not limited to this. In addition, according to some embodiments, in order to facilitate the subsequent construction process, in addition to the first auxiliary reinforcement FT1 and the second auxiliary reinforcement FT2, various auxiliary supports and other objects may also be provided, such as auxiliary support J that intersects the first auxiliary reinforcement FT1 and the second auxiliary reinforcement FT2 perpendicularly. These other variations should be understood by those skilled in the art, and therefore will not be described in detail below.

[0042] Next, referring to FIG11, the structural method according to this embodiment further includes an external stirrup structural step S30: a plurality of external stirrups 100 are arranged one by one along the beam extension direction DB, or a steel cage composed of the plurality of external stirrups 100 is arranged, such that the pair of horizontally extended portions 130, 140 of each of the external stirrups 100 are respectively supported on the first auxiliary bar FT1 and the second auxiliary bar FT2, so as to form a beam steel reinforcement base skeleton RF corresponding to the joint section JS extending from the column module CM along the beam extension direction DB.

[0043] Next, referring to Figure 12, the structural method according to this embodiment further includes the inner stirrup structural step S40: arranging a plurality of inner stirrups 200 one by one along the beam extension direction DB, or arranging a steel cage composed of the plurality of inner stirrups 200, such that the inner stirrups 200 are correspondingly arranged in the outer stirrup openings OP1 of the outer stirrups 100.

[0044] Secondly, referring to Figure 13, the structural method according to this embodiment further includes a beam lower layer main reinforcement structural step S50: entering through the outer stirrup opening OP1 and the joint section JS without stirrups and tie bars, and sequentially setting a plurality of beam lower layer main reinforcements V or setting a beam lower layer main reinforcement module formed by arranging the plurality of beam lower layer main reinforcements V. The plurality of beam lower layer main reinforcements V or the beam lower layer main reinforcement module formed by arranging the plurality of beam lower layer main reinforcements V can be supported by the lower confinement section LS below the joint section JS of the column module CM and the beam reinforcement base skeleton RF.

[0045] As described above, after completing step S50 of placing multiple beam lower main reinforcement bars V through the joint section JS of the column module CM to complete the beam lower main reinforcement structure, according to this embodiment, in step S55 of setting beam-column joint stirrups as shown in Figure 14, a beam-column joint stirrup structure EL containing at least one stirrup E1 can be further set in the joint section JS of the column module CM.

[0046] Then, referring to Figure 15, after the beam-column joint stirrup setting step S55, the structural method of this embodiment further includes the beam upper main reinforcement structural step S60: corresponding to the top of the outer stirrup opening OP1, a plurality of beam upper main reinforcement Ts are set one by one, or a beam upper main reinforcement module formed by arranging the plurality of beam upper main reinforcement Ts is set. Continuing above, the beam upper main reinforcement Ts or the beam upper main reinforcement module formed by arranging the plurality of beam upper main reinforcement Ts can be supported by the beam-column joint stirrup structure EL (e.g., including stirrup E1 and tie bar E2) of the joint section JS after passing through the column module CM, and thus extended along the beam extension direction DB on the joint section JS.

[0047] Furthermore, according to this embodiment, if the beam reinforcement structure 60 is expected to be configured with reverse inner stirrups 200', then referring to Figure 16, the reinforcement method according to this embodiment may also optionally include the reverse inner stirrup reinforcement structure step S70: on the upper main reinforcement T of these beams, a plurality of reverse inner stirrups 200' are successively hung and arranged along the extension direction DB of the beam, or a reinforcement cage composed of a plurality of reverse inner stirrups 200' is hung and arranged. Wherein, as mentioned above, each of these reverse inner stirrups 200' may be U-shaped, and defines a reverse inner stirrup opening OP2' that opens towards the bottom section 105, and the aforementioned inner stirrup opening OP2 and the reverse inner stirrup opening OP2' face each other. As described above, in this configuration, the reverse inner stirrup structure step S70 may further include lapping the first vertical bar 210 of the corresponding inner stirrup 200 with the first reverse vertical bar 210' of the reverse inner stirrup 200', and lapping the second vertical bar 220 of the corresponding inner stirrup 200 with the second reverse vertical bar 220' of the reverse inner stirrup 200'.

[0048] According to some embodiments, in the reverse inner stirrup structure step S70, at least one stirrup E1 and at least one tie bar E2 can be further provided above the joint section JS to further establish the joint section JS in the opposite direction to the upper confinement section HS above the lower confinement section LS, thereby strengthening the positioning of the joint section JS and the upper main reinforcement T of the beam. Continuing above, the setting of the stirrup E1 and tie bar E2 of the upper confinement section HS can be carried out simultaneously with the setting of a plurality of reverse inner stirrups 200' or a reinforcement cage composed of a plurality of reverse inner stirrups 200'. Alternatively, the stirrup E1 and tie bar E2 of the upper confinement section HS can be set first, or a plurality of reverse inner stirrups 200' or a reinforcement cage composed of a plurality of reverse inner stirrups 200' can be set first, followed by the other in sequence. Continuing above, according to different embodiments of the present invention, the setting order of the upper confinement section HS and the plurality of reverse inner stirrups 200' can be selectively adjusted according to requirements.

[0049] Finally, referring to FIG17, the structural method according to this embodiment may further include a cap installation step S80: a plurality of stirrup cap assemblies 400 are provided on the top of the outer stirrup opening OP1 to bridge between the first auxiliary reinforcement FT1 and the second auxiliary reinforcement FT2 and supported by the upper main reinforcement T of the beam, thereby covering the outer stirrup opening OP1. For example, according to this embodiment, the stirrup cap assembly 400 may each include a first stirrup cap 410 and a second stirrup cap 420, and the cap installation step S80 includes: covering a portion of the outer stirrup opening OP1 of the upright portion 110 with the first stirrup cap 410, such that the opposite ends of the first stirrup cap 410 are respectively attached to the first auxiliary reinforcement FT1 and one of the upper beam main reinforcements T; covering a portion of the outer stirrup opening OP1 of the upright portion 120 with the second stirrup cap 420, such that the opposite ends of the second stirrup cap 420 are respectively attached to the second auxiliary reinforcement FT2 and another upper beam main reinforcement T; and overlapping the sections of the first stirrup cap 410 and the second stirrup cap 420 disposed on the upper beam main reinforcements T. Thus, the steel reinforcement system 1000 including the beam steel reinforcement structure 60 can be finally completed.

[0050] Furthermore, according to some embodiments, if stirrups E1 and tie bars E2 are not further installed on the joint section JS in the above-mentioned reverse inner stirrup structure step S70, the upper confinement section HS on the joint section JS can be further established in this cap installation step S80, thereby strengthening the positioning of the joint section JS and the upper main reinforcement T of the beam. Continuing above, the installation of stirrups E1 and tie bars E2 on the upper confinement section HS can be carried out simultaneously with the installation of the stirrup cap assembly 400. Alternatively, the stirrups E1 and tie bars E2 on the upper confinement section HS can be installed first, or the stirrup cap assembly 400 can be installed first, followed by the other sequentially. Continuing above, according to different embodiments of the present invention, the installation order of the upper confinement section HS and the stirrup cap assembly 400 can be selectively adjusted according to requirements.

[0051] According to this embodiment, as shown in the construction framework of the process in Figures 10 to 17, the stirrup cap assembly 400 and the inner stirrup 200 can be bridged by the intermediate reverse inner stirrup 200'. However, according to other embodiments (not shown), if there is no intermediate reverse inner stirrup 200', since the inner stirrup 200 has a first vertical bar 210 and a second vertical bar 220, and the first stirrup cap 410 has a first hanging portion N1 at one end opposite to the first auxiliary bar FT1, and the second stirrup cap 420 has a second hanging portion N2 at one end opposite to the second auxiliary bar FT2, the cap installation step S80 can also include: lapping the first hanging portion N1 extending into the outer stirrup opening OP1 with the corresponding second vertical bar 220; and lapping the second hanging portion N2 extending into the outer stirrup opening OP1 with the corresponding first vertical bar 210. As mentioned above, these variations can be deduced from the descriptions in Figures 1 to 17, and will not be repeated here.

[0052] Referring further to Figure 18, according to one embodiment of the present invention, similar to the configuration shown in Figures 1 to 17, the planned installation block of the joint section JS of the column module CM' may not have stirrups E1 or tie bars E2 in the beam-column joint stirrup structure during the process stage. Therefore, in the process S100 of the construction method of the steel reinforcement system 2000 including the beam steel reinforcement frame 60, the beam main reinforcement module BM, which integrates and arranges multiple beam main reinforcements (e.g., the lower layer main reinforcement V of the beam), can be directly set in the beam reinforcement base skeleton RF constructed by the outer stirrup 100 through the outer stirrup opening OP1. As mentioned above, according to the configuration shown in Figure 18, similar to the application configuration shown in Figure 9, it is more convenient to simultaneously set multiple beam main reinforcements, thereby improving the efficiency and yield of setting multiple beam main reinforcements, and reducing or avoiding the test of the construction worker's skills.

[0053] As shown in Figure 18, details that are the same as or similar to those described with reference to Figures 10 to 17 will not be repeated, and those with ordinary knowledge in the relevant technical field should be able to understand the corresponding details and variations.

[0054] In summary, the beam reinforcement structure and the reinforcement system therein proposed according to the embodiments of the present invention can improve the convenience of the construction process and reduce or avoid interference or conflict between various structures. Therefore, the beam reinforcement structure and the reinforcement system therein proposed according to the embodiments of the present invention can help reduce the materials, costs, and effort required in the construction process, and can further improve the appearance, integrity, and reliability of the completed product.
