Description

Technical Field

[0001] The utility model relates to the technical field of assembled prefabricated beam production equipment, in particular to a hydraulically adjustable prefabricated beam reinforcement cage frame. Background Art

[0002] In the production of industrialized prefabricated beams, the assembly of steel cages has always been the focus and difficulty. The accuracy of steel cage assembly affects the final yield of prefabricated beams, and the reuse rate of steel cage frames affects the cost of prefabricated beams. Since fixed steel frames are generally used in the production of prefabricated beams, the accuracy of steel bar assembly and welding is very high, and only prefabricated beams with one cross-section can be processed. Therefore, improving the accuracy of assembly welding and improving the turnover rate of steel cage frames have become very critical points in the construction of steel cage assembly.

[0003] CN114407191A discloses a jig for making a pre-set box girder reinforcement skeleton, which can adjust the distance and angle of the first positioning rod and the second positioning rod on both sides relative to the bottom plate reinforcement positioning structure to correspond to the cross-sectional shape of the box girder reinforcement cage, and has a certain degree of versatility, but has the following disadvantages: 1. The position of the web reinforcement positioning structure is not adjustable, so the upper and lower positions of the web reinforcement of the prepared reinforcement cage are determined, and the spacing is not adjustable; 2. The angle of the web reinforcement positioning structure is not adjustable. If the web reinforcement has a double layer, it is not easy to place it on the inclined web reinforcement positioning structure; 3. The gantry frame structure is adopted, which is bulky and has a relatively fixed size. Once it is manufactured, it cannot be expanded. Utility Model Content
