[0018] Example 1

[0019] like Figure 1-2 The semi-automatic steel bar processing frame of a large cantilever cap beam shown in the figure can improve the production efficiency and quality of the semi-finished steel bar cage of the cap beam, which includes a bottom mold frame 1, and a fixed end side mold frame 2 and a movable end side mold frame 3 arranged in parallel on the bottom mold frame 1, one end of the fixed end side mold frame 2 is provided with an end limit mold frame 4 close to the movable end side mold frame 3 to form an open top working area, the end limit mold frame 4 and the fixed end side mold frame 2 are provided with a fixed working platform 5 that is mutually connected and used for workers to pass through, and when avoiding the working area, the end limit mold frame 4 and the fixed end side mold frame 2 are provided with a fixed working platform 5 that is mutually connected and used for workers to pass through. The working area is also provided with a working platform step ladder 6 for workers to enter the fixed working platform 5; a jacking mechanism 31 is provided on the mobile end side formwork 3, and a corbel limit baffle 32 located above the working area is provided on the top of the jacking mechanism 31, and a transverse support rod 33 for placing the cap beam reinforcement skeleton piece is provided on the corbel limit baffle 32. During the construction process, the height of the transverse support rod 33 can be raised and lowered by controlling the jacking mechanism 31, which is convenient for lifting out the semi-finished cap beam reinforcement cage, reducing the lifting height of the truss crane, and improving work efficiency. The labor cost is reduced to a certain extent; the mobile end side formwork 3 is also provided with a mobile working platform 34 on the side close to the working area, and the position of the mobile end side formwork 3 is adjusted to cooperate with the main reinforcement positioning tooth plate 12 on the bottom formwork 1 to realize the accurate positioning and pre-fixation of the cap beam reinforcement skeleton piece; the top of the bottom formwork 1 is provided with a distribution beam, and the distribution beam is located at a position away from the end limit formwork 4, and the distribution beam is sequentially provided with a pier column reinforcement reservation device 11 and a main reinforcement positioning tooth plate 12 in the direction away from the end limit formwork 4. Specifically, Both the pier column reinforcement pre-reserved device 11 and the main reinforcement positioning tooth plate 12 have multiple positioning grooves for the main reinforcement and assembled pier column reinforcement to pass through. The positioning grooves are used to accurately locate the main reinforcement, stirrups and prestressed pipe positions of the cap beam to avoid conflicts with the position of the pier column main reinforcement during overall lifting, which greatly improves the processing accuracy of the semi-finished product of the cap beam reinforcement cage and the on-site lifting efficiency; the fixed end side formwork 2 is provided with a stirrup positioning tooth plate 21 on the side close to the working area, and the top of the fixed end side formwork 2 is equipped with a cantilever storage crane 7 for placing welding equipment.

[0020] During implementation, first, the cap beam reinforcement skeleton plate placed in the working area is lifted up by controlling the jacking mechanism 31 using the transverse support rod 33, and then the mobile end side formwork 3 is adjusted to cooperate with the main reinforcement positioning tooth plate 12 on the bottom formwork 1 to accurately position and pre-fix the cap beam reinforcement skeleton plate, and the stirrup positioning tooth plate 21 on the fixed end side formwork 2 is used to accurately position and fix the stirrups, and then the main reinforcement positioning tooth plate 12 on the bottom formwork 1, the pier column reinforcement reservation device 11 and the stirrup positioning tooth plate 21 on the fixed end side formwork 2 are used to perform the accurate positioning and laying of the cap beam main reinforcement and the subsequent sleeve connection work, and finally, with the assistance of the fixed working platform 5 and the mobile working platform 34, all the steel sleeve connections, welding and binding are completed to obtain the cap beam reinforcement cage. After the construction of the semi-finished cap beam reinforcement cage is completed, the height of the transverse support rod 32 is lowered by controlling the jacking mechanism. The semi-finished cap beam reinforcement cage with a lowered height is convenient for the truss crane to take out, and the lifting height of the truss crane is also reduced, thereby reducing the height requirement for the reinforcement yard construction, directly reducing the construction cost of the reinforcement processing yard, and shortening the construction period of the reinforcement yard. The entire operation process is mostly carried out on the fixed working platform 5 and the mobile working platform 34, which can reduce the long-term high-altitude operation of construction personnel and thus reduce safety risks.

[0021] As a preferred solution of the above embodiment, the fixed end side mold frame 2 is connected to the cantilever storage crane 7 via a slide rail 8, which is convenient for moving the cantilever storage crane 7 and further facilitates the welding operation.

[0022] As a preferred solution of the above embodiment, the cantilever storage crane 7 has a welding equipment placement area 71 and a tool placement area 72 .

[0023] Of course, the present invention may have many other implementation modes. Without departing from the spirit and essence of the present invention, technicians familiar with the field may make various corresponding changes and deformations based on the present invention, but these corresponding changes and deformations should all fall within the scope of protection of the claims attached to the present invention.
