Description

Technical Field

[0001] This utility model belongs to the field of positioning technology for cap beam stirrups, and more specifically, relates to a slidable and fixed platform toothed plate device. Background Technology

[0002] In bridge construction, the cap beam, as a load-bearing component, directly affects the safety and durability of the structure due to the quality of its reinforcing steel reinforcement cage binding. During the reinforcement binding process, the spacing between the main bars and stirrups must be strictly controlled to meet design requirements and specifications. To improve binding efficiency and accuracy, positioning teeth are typically used to spatially position the main bars and stirrups, thereby achieving standardized control of the reinforcement spacing. However, in actual construction, existing positioning teeth are mostly fixed, integrated structures, leading to interference problems when placing stirrups, affecting construction efficiency and quality.

[0003] To address the issue of rebar positioning during the binding of the rebar cage in cap beams, existing technologies commonly employ fixed positioning toothed plate structures. These structures, typically made of metal, feature multiple equally spaced positioning slots for engaging main bars or stirrups, thus achieving standardized control of rebar spacing. By embedding the main bars or stirrups into the corresponding slots, construction workers can accurately control the rebar spacing, avoiding offsets or misalignments that occur during manual binding. Furthermore, this structure possesses a certain degree of rigidity and stability, capable of withstanding the self-weight of the rebars and external forces during construction, thereby ensuring the overall quality of the rebar cage. Some existing technologies also attempt to improve applicability by optimizing the toothed plate arrangement or adding auxiliary support structures. For example, some solutions use multi-segment spliced ​​toothed plates, combining toothed plates of different lengths to adapt to cap beam structures of different sizes. These improvements, to some extent, enhance the flexibility and adaptability of the positioning toothed plates.

[0004] Although existing technologies have made some progress in rebar positioning, there are still many shortcomings in practical applications, especially in the installation of stirrups. For example, since most existing positioning teeth are fixed structures with non-adjustable tooth positions, the positioning teeth on the teeth may physically obstruct the vertical lowering of the stirrups. This obstruction is more pronounced in areas with dense rebar or complex structures, forcing construction workers to temporarily remove part of the teeth to complete the stirrup installation. This not only increases construction steps and reduces efficiency, but also compromises the positioning accuracy of the stirrups after removal, making it difficult to meet design requirements for rebar spacing and affecting the overall structural quality. Furthermore, fixed teeth have poor versatility and are difficult to adapt to different specifications of cap beam structures. This often necessitates redesigning or replacing teeth for projects with different dimensions or rebar layout requirements, increasing equipment costs and management difficulty. At the same time, the installation and dismantling process of teeth is cumbersome, increasing the labor intensity of construction workers and reducing the convenience and safety of construction.
