Description

Technical Field

[0001] This invention relates to the field of elevator shaft formwork technology, and in particular to a rapid formwork structure for elevator shafts and its construction method. Background Technology

[0002] Elevator shaft formwork systems play a vital role in construction. They not only ensure construction quality and progress but also improve construction efficiency and reduce unnecessary workload and labor costs. During use, attention must be paid to the inspection and maintenance of the formwork, and operations must be strictly carried out in accordance with design and construction requirements. In general, elevator shaft formwork systems are one of the most important building construction tools, playing a significant role in improving construction quality and efficiency.

[0003] Chinese patent CN101824910B proposes a rapid formwork construction method for elevator shafts. First, a support frame consisting of a bottom stretcher, middle columns, and a top work platform is constructed at the bottom of the elevator shaft. The top work platform is matched to the size of the elevator shaft. The lower end of the bottom stretcher rests against the elevator door, and its upper end rests on the elevator shaft wall opposite the door. The upper end of the middle column is hinged to the bottom surface of the top work platform. The lower end of one set of middle columns is hinged to the upper frame of the bottom stretcher, while the lower end of the other set is secured to the bottom stretcher. Then, inner and outer wall formwork and external scaffolding are constructed on the top work platform for pouring the elevator shaft walls. After pouring one floor of the elevator shaft, the inner wall formwork is moved inward away from the wall, and the outer wall formwork is removed. The support frame is then raised one floor using a vertical lifting device. The inner wall formwork is then moved outward closer to the wall, and the outer wall formwork is repeatedly constructed to complete the pouring of the next floor's elevator shaft walls.

[0004] The above solution allows for rapid formwork construction of elevator shafts from bottom to top without the need for repeated assembly and disassembly of supporting scaffolding and wall formwork. This effectively increases the construction speed of elevator shafts, reduces the labor intensity of workers, improves construction efficiency, reduces construction costs, and ensures operational safety. However, the above solution requires manual fixing of the formwork structure, which not only requires a large amount of labor but also easily leads to insecure fixing of the formwork structure, posing certain safety hazards and reducing the safety of the rapid formwork structure in elevator shafts. Summary of the Invention

[0005] The purpose of this invention is to provide a rapid formwork structure for elevator shafts and its construction method in order to solve the above-mentioned problems. This device utilizes the cooperation between the lifting assembly, the electric hydraulic cylinder, the fixing plate, and the fixing pin to fix the rapid formwork structure.

[0016] As a preferred embodiment of the present invention, a rapid formwork construction method for elevator shafts includes the following steps:

[0017] S1: The workers use the connecting components to fix the formwork components. The workers place the installation base on one side of the elevator shaft body, start the electric hydraulic cylinder, the electric hydraulic cylinder drives the fixing plate to adjust downward, the fixing plate drives the fixing pin to adjust downward, and insert the four fixing pins into the soil to fix the rapid formwork structure.

By inserting multiple fixing pins into the soil, the rapid formwork structure can be fixed. It is not necessary for workers to manually knock the fixing pins to fix the rapid formwork structure, so that the rapid formwork structure is fixed more firmly and the stability of the rapid formwork structure of the elevator shaft is improved.

[0021] By setting up the cooperation between the bidirectional electric telescopic rod, T-shaped plate, locking block, connecting block and locking slot, the bidirectional electric telescopic rod can drive the distance between the two T-shaped plates. The two T-shaped plates drive the locking block to adjust, which can adjust the locking block into the inside of the locking slot to fix the connecting block. This makes it easier to connect the quick formwork structure and the lifting component, making the connection more solid and convenient, and improving the practicality of the quick formwork structure.

[0022] By setting up a second motor, a winding wheel, a connecting shaft, an adjusting belt, and a placement box, the second motor can drive the winding wheel to rotate. The two winding wheels can wind up the adjusting belt, which can lift and lower the placement box, placing the material inside the placement box for feeding. This makes feeding more convenient and improves the ease of use of the elevator shaft's rapid formwork structure. Attached Figure Description
