Factory prefabricated elevator well foundation pit and mounting method thereof

Abstract

The invention discloses a factory prefabricated elevator well foundation pit, and prefabricating and mounting methods thereof. The elevator well foundation pit adopts a reinforced concrete structure and comprises a top ring beam, a bottom ring beam, four corner columns, walls and a bottom plate; the bottom ring beam is located on the peripheral side of the bottom plate; the upper ends and the lower ends of the corner columns are located at the four corners of the top ring beam and the bottom ring beam correspondingly; the walls are located between the adjacent corner columns, and a cuboid withthe upper end open is defined by the walls, the corner columns, the top ring beam, the bottom ring beam and the bottom plate; and top buried pieces are arranged at the four corners of the top face ofthe top ring beam correspondingly, bottom buried pieces are arranged at the four corners of the bottom face of the bottom ring beam correspondingly, and well inner buried pieces are arranged on the walls and the bottom plate in the foundation pit correspondingly. According to the factory prefabricated elevator well foundation pit, and the prefabricating and mounting methods thereof, the elevatorwell foundation pit is prefabricated in a factory, due to the fact that the elevator well foundation pit is shaped, machined and manufactured in the factory, industrialization can be formed, elevatorwell foundation pits with the same model specification in a batch of orders can be subjected to shaping production, and the speed is high.

Description

technical field [0001] The invention specifically relates to a factory-prefabricated elevator shaft foundation pit. Background technique [0002] The concrete foundation pits of the existing elevator shafts are all manufactured by on-site construction, and the on-site construction has the following defects: [0003] 1. Many processes, long cycle, time-consuming and labor-intensive; [0004] 2. During on-site construction, the on-site pouring quality of concrete and the appearance of the finished surface are always lacking; [0005] 3. When the formwork is supported on site, the noise of the cutting board is large, which is not environmentally friendly; [0006] 4. Affected by the on-site measurement environment, the position of the embedded parts in the shaft foundation pit always deviates; [0007] 5. On-site construction is greatly affected by weather factors. Contents of the invention [0008] The purpose of the present invention is to solve the defects in the prior...
