Description

Technical Field

[0001] The utility model relates to the technical field of elevator shaft construction, in particular to a shrinkage template used for elevator shaft construction. Background Art

[0002] Formwork engineering is a temporary support system for cast-in-place concrete, which is extremely important for controlling the shape of the structure and the main structure. Most elevator shafts are equipped with partition beams. At least two areas of the elevator shaft need to be repaired. At the same time, it involves elevator track construction, repeated erection of shaft frames, and limited operating space. In order to ensure the installation of formwork in the elevator shaft, an operating platform is required. The hydraulic climbing formwork platform used is 2.3m wide and 16.1m high, covering 3-4 storeys in total. Combined with the actual situation on the project site, tilting, collision with upper beams and refuge beams, and steel formwork tension screws often occur during the climbing process. The rod collides with the longitudinal reinforcement of the shear wall and cuts off the main reinforcement, and the verticality and flatness of the template are difficult to control. At the same time, the construction progress of the elevator shaft on site is seriously delayed because the concrete needs to reach the standard strength before the reinforcement binding work of the upper layer can be started. It is difficult to effectively connect the relevant construction processes. The house formwork project is the key force-bearing part in the construction. The change of force mode will increase the difficulty of formwork construction. In the past, the design and construction of the building formwork project could not meet the force requirements, which made the design of the template not match the project, the force was uneven, and the formwork support was unstable. The traditional engineering construction method has limitations, which is not conducive to the development of construction. The lack of reasonable application of new technologies in various construction links seriously affects the quality and efficiency of construction. Utility Model Content
