Technical Field
[0001] This utility model relates to the field of steel reinforcement cage technology, specifically to a prefabricated uniform cross-section simply supported T-beam steel reinforcement cage. Background Technology
[0002] Precast 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. Therefore, a prefabricated uniform cross-section simply supported T-beam reinforcing bar cage is proposed. Utility Model Content

[0027] 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.
[0028] Example:
[0029] like Figure 1 - Figure 8As shown, this utility model provides a prefabricated uniform cross-section simply supported T-beam reinforcement cage, including a T-beam top plate reinforcement assembly 1 and a T-beam web reinforcement assembly 2. The T-beam web reinforcement assembly 2 is disposed in the middle of the T-beam top plate reinforcement assembly 1. The T-beam web reinforcement assembly 2 and the T-beam top plate reinforcement assembly 1 are overlapped and the T-beam top plate reinforcement assembly 1 and the T-beam web reinforcement assembly 2 cooperate to form a reinforcement cage group. Several groups of reinforcement cages are provided, and the several groups of reinforcement cages are arranged longitudinally at equal intervals. A joint connection part 3 is formed at the overlap of the T-beam web reinforcement assembly 2 and the T-beam top plate reinforcement assembly 1. A connecting bar 4 is inserted into the joint connection part 3, and the connecting bar 4 is connected to the T-beam top plate reinforcement assembly 1 and the T-beam web reinforcement assembly 2 by welding.
[0030] Several groups of simply supported T-beam reinforcement cages, together with connecting bars 4, constitute the simply supported T-beam reinforcement cage.
[0031] The T-beam top slab reinforcement assembly 1 includes top slab transverse reinforcement 11 and top slab longitudinal reinforcement 12;
[0032] Several sets of longitudinal reinforcement bars 12 are provided in the top slab. These sets of longitudinal reinforcement bars 12 are welded to the inside of both sides of the transverse reinforcement bars 11 in the top slab. The number of longitudinal reinforcement bars 12 inside the transverse reinforcement bars 11 is the same on both sides. During operation, the sets of longitudinal reinforcement bars 12 are arranged longitudinally. Each set of longitudinal reinforcement bars 12 is composed of several sets of longitudinal reinforcement bars 121. The longitudinal reinforcement bars 121 in the horizontally arranged sets of longitudinal reinforcement bars 12 are spaced at the same interval. According to the specifications of the reinforcement cage, several sets of transverse reinforcement bars 11 are arranged transversely above the arranged longitudinal reinforcement bars 12. After the transverse reinforcement bars 11 are arranged, a welding robot is used to weld the arranged transverse reinforcement bars 11 and longitudinal reinforcement bars 12. After welding, the transverse reinforcement bars 11 and longitudinal reinforcement bars 12 form a planar mesh.
[0033] like Figure 2 As shown, the planar mesh formed by the transverse steel bars 11 and the longitudinal steel bars 12 of the top slab is bent into a shape using a bending device. After the shape is completed, several groups of longitudinal steel bars 12 on the same side of the transverse steel bars 11 are stacked vertically. In the stacked state, the longitudinal steel bars 121 in each group of longitudinal steel bars 12 are on the same vertical line. When the longitudinal steel bars 121 in the same group of longitudinal steel bars 12 are located at different segments of the transverse steel bars 11, the setting position of the longitudinal steel bars 121 is adaptively adjusted to correspond to the vertical line, so that the longitudinal steel bars 121 on the same vertical line correspond.
[0034] T-beam web reinforcement assembly 2 includes web stirrups 21 and web longitudinal reinforcement group 22;
[0035] Two sets of longitudinal reinforcement bars 22 are provided in the web plate. The two sets of longitudinal reinforcement bars 22 are welded to the inner sides of the web plate stirrups 21 respectively. Each set of longitudinal reinforcement bars 22 consists of several sets of longitudinal reinforcement bars 221. During operation, the longitudinal reinforcement bars 221 in the two sets of longitudinal reinforcement bars 22 are arranged longitudinally. After the arrangement, several sets of web plate stirrups 21 are arranged transversely above the two transverse reinforcement bars 11 of the top plate. After the web plate stirrups 21 are arranged, the arranged web plate stirrups 21 and web plate longitudinal reinforcement bars 221 are welded by a welding robot. After the web plate stirrups 21 and web plate longitudinal reinforcement bars 221 are welded, a planar mesh is formed.
[0036] like Figure 3 As shown, the planar mesh formed by the web stirrups 21 and the longitudinal web bars 221 is bent into a shape by a bending device. The top plate transverse bars 11 and the web stirrups 21 are both formed by bending. The ends of the top plate transverse bars 11 and the web stirrups 21 are welded together after bending. After welding, the top plate transverse bars 11 and the top plate longitudinal bars 12 form a closed loop.
[0037] As shown in the figure, there are several sets of connecting bars 4. These sets of connecting bars 4 are respectively set on the side of the intersection of the top plate transverse reinforcement 11 and the web plate stirrups 21. The connecting bars 4 are simultaneously welded to the top plate transverse reinforcement 11 and the web plate stirrups 21. Under the support of the connecting bars 4, the setting position and setting state of the web plate stirrups 21 and the top plate transverse reinforcement 11 remain fixed, thus forming a complete simply supported T-beam reinforcement skeleton.
[0038] The bottom of the web stirrups 21 is provided with several sets of web bottom bars 5. The several sets of web bottom bars 5 are evenly distributed at the bottom of the web stirrups 21 and are connected to the web stirrups 21 by welding. Under the support of the web bottom bars 5, the structural stability of the formed simply supported T-beam steel reinforcement skeleton is further enhanced. The final simply supported T-beam steel reinforcement skeleton can be used for subsequent pouring operations.

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.
