Description

Technical Field

[0001] The invention relates to the technical field of civil engineering prefabricated component installation, and in particular to an installation method for a combined structure of a theme park composite slab and a cast-in-place frame beam. Background Art

[0002] In theme park projects, although most buildings have only one floor, there are many special-shaped structures and they are very complex. There are great limitations in the actual construction process of prefabricated components, especially in the combination of composite slabs and cast-in-place beams. The traditional practice is to tie the frame beam reinforcement first, and then hoist the composite slabs. Due to the structural limitations of the park, most composite slabs have cast-in-place frame beam reinforcements all around. The composite slabs can only be tilted to put in reinforcements in one direction, and the composite slab reinforcements in the other directions must be bent. After the composite slab is hoisted, the slab reinforcements are restored again, resulting in repeated bending of the composite slab reinforcements. In addition, due to the complex structure, the operating space is limited, and some composite slab reinforcements cannot be restored to their original state, seriously affecting the structural safety function. Summary of the invention

[0003] The present invention aims to overcome the defects of the prior art and provide an installation method for a combination structure of a theme park composite slab and a cast-in-place frame beam, so as to solve the problem of repeated bending of composite slab reinforcement in the combination structure of the theme park composite slab and the cast-in-place frame beam.

[0005] The installation method of the combined structure of the theme park composite slab and the cast-in-place frame beam is characterized in that: in step 2, 12 cm high horse stool reinforcement is prepared, and the rear drop beam is supported on the bottom template of each beam to ensure that there is sufficient construction operation space when installing the upper reinforcement of the beam.

[0006] The installation method of the combination structure of the composite slab and cast-in-place frame beam of a theme park is characterized by: in step three, according to the order of the drawing, ensure that the position of each composite slab is consistent with the support formwork. In the process, if the composite slab reinforcement and the frame beam stirrups overlap, the stirrup position needs to be fine-tuned.

[0007] The method for installing a theme park composite slab and cast-in-place frame beam combination structure is characterized in that: in step five, during installation, if there is a conflict between the frame beam steel bars and the frame column steel bars, fine-tuning is performed.

[0008] The installation method of the combined structure of the theme park composite slab and the cast-in-place frame beam is characterized in that after the waist reinforcement and the upper longitudinal reinforcement of the frame beam are installed, the horse stool reinforcement is removed to make the overall steel bar skeleton of the frame beam fall to the bottom.

[0009] The installation method of the combined structure of the theme park composite slab and the cast-in-place frame beam is characterized in that a 3*3*2.5 cm pad is supported at the bottom of the frame beam to ensure the thickness of the steel bar protective layer of the frame beam.

[0010] The beneficial effects of the present invention are as follows: It can be seen from the above technical scheme that the present application provides a method for installing a composite slab of a theme park and a cast-in-place frame beam combination structure. Compared with the traditional method for installing a composite slab of a frame beam combination structure, the composite slab hoisting steps are simplified, part of the labor cost is saved, and the problem of repeated bending or inability to restore the composite slab reinforcement after bending in the composite slab of a theme park and a cast-in-place frame beam combination structure is solved, thereby improving the safety performance of the main structure.
