Technical Field
[0001] This utility model relates to the field of steel frame technology, specifically to a simple-supported T-beam steel frame with uniform cross-section that eliminates the need for post-installed longitudinal reinforcing bars. Background Technology
[0002] Simply supported T-beams are a structural type used in small and medium-span bridges. The main materials are steel bars and concrete. The fabrication process of precast beams usually includes steps such as steel bar processing, assembly and welding, concrete pouring and prestressing tensioning. Among these, steel bar processing and assembly are key links, which directly affect the quality and efficiency of precast beams. In traditional construction methods, these tasks are mainly done manually, which is time-consuming, labor-intensive and difficult to guarantee quality.
[0003] However, due to the complexity of T-beam structures, the shapes and sizes of reinforcing bars vary, and machinery cannot meet all the requirements for processing reinforcing bars, which limits the full automation rate of reinforcing bar cage production. To address this, a simple supported T-beam reinforcing bar cage with uniform cross-section that eliminates the need for post-threading of longitudinal reinforcing bars is proposed. Utility Model Content
[0004] In order to solve the technical problems existing in the prior art, the present invention provides a simple supported T-beam reinforcement cage with uniform cross-section that eliminates the need for post-installation longitudinal reinforcement.
[0005] To solve the above technical problems, this utility model provides the following technical solution: a simply supported T-beam reinforcement skeleton with uniform cross-section and no need for post-reinforcing longitudinal bars, comprising a top plate transverse portion and a web longitudinal portion. The top plate transverse portion is provided with two sets, which are installed above the web longitudinal portion by interlocking. The top plate transverse portion and the web longitudinal portion cooperate to form a simply supported T-beam reinforcement skeleton. The top plate transverse portion includes a first top plate transverse bar, a second top plate transverse bar, a first top plate longitudinal bar, and a second top plate longitudinal bar. The first top plate transverse bar and the second top plate transverse bar are connected opposite each other. The first top plate longitudinal bar and the second top plate longitudinal bar are interlocked inside the first top plate transverse bar and the second top plate longitudinal bar, respectively. The web longitudinal portion includes web stirrups, web top reinforcement bars, and web bottom reinforcement bars. The web top reinforcement bars and the web bottom reinforcement bars are respectively located at the top and bottom of the web stirrups. The first top plate transverse bar and the second top plate transverse bar overlap above the web top reinforcement bars.
[0006] Preferably, the first and second transverse reinforcing bars of the top slab have the same specifications, and the lower ends of the first and second transverse reinforcing bars of the top slab are staggered.
[0007] Preferably, the ends of the first and second transverse reinforcing bars of the top slab are connected by welding, and the lower ends of the first and second transverse reinforcing bars of the top slab are misaligned and abutted, and fixed by welding.
[0008] Preferably, both the first and second transverse reinforcement bars of the top slab are bent into shape, and the first and second longitudinal reinforcement bars of the top slab are vertically aligned with each other as the first and second transverse reinforcement bars of the top slab are bent.
[0009] Preferably, at least three sets of top-layer reinforcing bars are provided in the web, and the three sets of top-layer reinforcing bars are respectively provided on both sides and the middle of the top of the web stirrups.
[0010] Preferably, the longitudinal portion of the web further includes longitudinal reinforcing bars, and the longitudinal reinforcing bars of the web are provided in two sets, which are respectively provided on both sides of the inner wall of the web stirrups.
[0011] Preferably, the longitudinal portion of the web further includes a top plate transverse reinforcement stabilizing bar, which is located at the intersection of the lower ends of the first and second top plate transverse reinforcement bars, and is welded to both the first and second top plate transverse reinforcement bars.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. This utility model provides a top plate transverse section, which includes a first top plate transverse reinforcement, a second top plate transverse reinforcement, a first top plate longitudinal reinforcement, and a second top plate longitudinal reinforcement. The first top plate longitudinal reinforcement and the second top plate longitudinal reinforcement are respectively interspersed inside the first top plate transverse reinforcement and the second top plate transverse reinforcement. The first top plate transverse reinforcement and the second top plate transverse reinforcement overlap the top layer reinforcement of the web longitudinal section and are connected by welding. The top plate transverse section and the web longitudinal section are both prefabricated by mechanization and then installed on the web longitudinal section by lateral assembly and welding, which improves the mechanization rate of irregular steel bars, reduces production time, and improves the yield rate.
[0015] 2.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments, highlighting the above and other technical features and advantages of the present invention. However, the following embodiments are merely preferred embodiments of the present invention and are not exhaustive.
[0025] Example:
[0026] like Figure 1 - Figure 6As shown, this utility model provides a simple-supported T-beam reinforcement cage with uniform cross-section and no need for post-reinforcing longitudinal bars, including a top plate transverse part 1 and a web longitudinal part 2. The top plate transverse part 1 has two sets, which are installed above the web longitudinal part 2 by interlocking. The top plate transverse part 1 and the web longitudinal part 2 cooperate to form a simple-supported T-beam reinforcement cage. The top plate transverse part 1 includes a first top plate transverse bar 11, a second top plate transverse bar 12, a first top plate longitudinal bar 13, and a second top plate longitudinal bar 14. The first top plate transverse bar 11 and... The second top plate transverse reinforcement 12 is connected in opposite directions. The first top plate transverse reinforcement 11 and the second top plate transverse reinforcement 12 are respectively interspersed with the first top plate longitudinal reinforcement 13 and the second top plate longitudinal reinforcement 14. The longitudinal part of the web plate 2 includes web plate stirrups 21, web plate top reinforcement 22 and web plate bottom reinforcement 23. The web plate top reinforcement 22 and the web plate bottom reinforcement 23 are respectively set at the top and bottom of the web plate stirrups 21. The first top plate transverse reinforcement 11 and the second top plate transverse reinforcement 12 overlap above the web plate top reinforcement 22.
[0027] The first transverse reinforcement 11 and the second transverse reinforcement 12 of the top slab have the same specifications. The lower ends of the first transverse reinforcement 11 and the second transverse reinforcement 12 of the top slab are staggered. By staggering them, the lower ends of the first transverse reinforcement 11 and the second transverse reinforcement 12 of the top slab will not interfere with each other and will remain in an extended state.
[0028] The ends of the first top plate transverse reinforcement 11 and the second top plate transverse reinforcement 12 are connected by welding. The lower ends of the first top plate transverse reinforcement 11 and the second top plate transverse reinforcement 12 are misaligned and abutted and fixed by welding. After welding connection, the first top plate transverse reinforcement 11 and the second top plate transverse reinforcement 12 form a whole, so that the transverse part 1 of the top plate can be fitted on the upper part of the longitudinal part 2 of the web.
[0029] The first transverse reinforcement 11 and the second transverse reinforcement 12 of the top slab are both bent. The first longitudinal reinforcement 13 and the second longitudinal reinforcement 14 of the top slab are vertically aligned with the first transverse reinforcement 11 and the second transverse reinforcement 12 of the top slab as they are bent. The first longitudinal reinforcement 13 and the second longitudinal reinforcement 14 of the top slab work together to support the first transverse reinforcement 11 and the second transverse reinforcement 12 of the top slab, so that several groups of the first transverse reinforcement 11 and the second transverse reinforcement 12 of the top slab are combined into a whole.
[0030] At least three sets of top-layer web reinforcement 22 are provided. The three sets of top-layer web reinforcement 22 are respectively provided on both sides and the middle of the top of the web stirrups 21. The top-layer web reinforcement 22 provided at the middle position inside the second top-layer transverse reinforcement 12 corresponds to the position of the first top-layer transverse reinforcement 11 and the second top-layer transverse reinforcement 12. The first top-layer transverse reinforcement 11 and the second top-layer transverse reinforcement 12 are kept in the middle of the web stirrups 21 under the corresponding indication of the top-layer web reinforcement 22, so as to avoid the deviation of the top-layer transverse part 1 relative to the web longitudinal part 2.
[0031] The longitudinal part 2 of the web plate also includes longitudinal reinforcement bars 24 of the web plate. There are two sets of longitudinal reinforcement bars 24 of the web plate. The two sets of longitudinal reinforcement bars 24 of the web plate are respectively set on both sides of the inner wall of the web plate stirrups 21. The longitudinal reinforcement bars 24 of the web plate connect the side walls of several sets of web plate stirrups 21, so that several sets of web plate stirrups 21 further form an integral whole and improve the structural strength.
[0032] The longitudinal portion 2 of the web also includes a top plate transverse reinforcement stabilizing bar 25. The top plate transverse reinforcement stabilizing bar 25 is located at the intersection of the lower ends of the first top plate transverse reinforcement 11 and the second top plate transverse reinforcement 12. The top plate transverse reinforcement stabilizing bar 25 is pre-installed inside the web stirrups 21. Before the lower ends of the first top plate transverse reinforcement 11 and the second top plate transverse reinforcement 12 of several groups of top plate transverse portions 1 intersect, the top plate transverse reinforcement stabilizing bar 25 is raised to the position above the intersection. The top plate transverse reinforcement stabilizing bar 25 is simultaneously welded to the first top plate transverse reinforcement 11 and the second top plate transverse reinforcement 12. The bottom of several groups of top plate transverse portions 1 are connected by welding the top plate transverse reinforcement stabilizing bar 25 to the first top plate transverse reinforcement 11 and the second top plate transverse reinforcement 12.
[0033] The ends of the first transverse reinforcement 11 and the second transverse reinforcement 12 of the top slab are both kept inside the web stirrups 21. During the subsequent pouring process, the first transverse reinforcement 11 and the second transverse reinforcement 12 of the top slab can be better connected to the web stirrups 21 by fusing with the concrete, thereby obtaining better structural strength.
[0034] The above description is merely a preferred embodiment of the present utility model and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present utility model, all of which will fall within the protection scope of the present utility model.
