Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering construction in transportation, in particular to a standardized tire frame for processing and installing prefabricated beam reinforcement bars. Background Art

[0002] The prefabricated small box girder reinforcement tyre is an auxiliary equipment used in the construction of prefabricated box girders, which can improve the efficiency and quality of reinforcement tying and save construction costs. At present, the traditional reinforcement tying method is to tie the bottom web reinforcement on the beam pedestal after the installation of the beam pedestal and the small box girder web formwork, then assemble the end formwork and place the inner formwork, and then tie the top plate reinforcement. The construction sequence is: 1. Installation of the pedestal and web formwork; 2. Tie the bottom web reinforcement and position the prestressed pipe; 3. Installation of the end formwork and anchor pad; 4. Installation of the inner formwork; 5. Tie the top plate reinforcement; 6. Pouring concrete. There are many shortcomings in the traditional prefabricated box girder reinforcement construction, such as the position of the reinforcement processing area and the tying area is not fixed, the semi-finished steel bar is time-consuming and laborious to transport, the thickness of the steel bar protective layer is difficult to control, the steel bar skeleton line shape control is difficult, the steel bar spacing is uneven, the steel bar skeleton is tied on the beam pedestal, the steel plate release agent of the beam pedestal is polluted, and the pedestal turnover cycle is long.

[0003] In response to these problems, special steel bar tying cradles are currently widely used in the construction field. There are mainly two types of self-made prefabricated box girder steel bar skeleton tying positioning cradles. One is a separate cradle with a bottom plate cradle and a web plate cradle separated, such as a prefabricated small box girder steel cage tying cradle disclosed in the existing patent document with announcement number CN220198068U. The other is a cradle in which the bottom plate cradle and the web plate cradle are connected in an articulated manner, such as a prefabricated small box girder steel bar tying bracket disclosed in the existing patent document with announcement number CN216540676U.

[0004] Although the above-mentioned patent documents disclose that the construction processes corresponding to these two types of tire frames have certain advantages over the traditional construction processes in terms of improving construction efficiency and quality. However, during the construction of the separated tire frame, after the bottom plate reinforcement is tied, the web tire frame is slid to the two sides of the bottom plate tire frame, and then the web reinforcement is tied. On the one hand, although the construction efficiency is improved to a certain extent compared with the traditional construction, the improvement effect is limited; on the other hand, because the web reinforcement tire frame slides into place, there will inevitably be errors, which will affect the positioning of the reinforcement, especially the control of the thickness of the protective layer; the tire frame connected by the bottom plate tire frame and the web tire frame in an articulated manner will also affect the work efficiency due to the rotation of the hinge during construction, and the control of the web protective layer is not very ideal.
