Prefabricated bearing platform form and mounting method thereof

Abstract

The invention discloses a prefabricated bearing platform form and a mounting method thereof. The prefabricated bearing platform form comprises a plurality of plate bodies which are in sequential matched end-to-end connection, wherein upper concave tongue-and-groove openings or lower concave tongue-and-groove openings are formed in two sides of the plate bodies, and the upper concave tongue-and-groove openings and the lower concave tongue-and-groove openings are matched with each other; and when the plate bodies are in matched connection with the adjacent plate bodies, the upper concave tongue-and-groove openings in the plate bodies are spliced with the lower concave tongue-and-groove openings of the adjacent plate bodies. The mounting method of the prefabricated bearing platform form comprises the following steps: pouring of a bedding layer of a bearing platform; lofting of the bearing platform; hoisting and splicing of the plate bodies; axis location; elevation review, back-filling treatment; and pouring of the bearing platform after back-filling and compacting. The prefabricated bearing platform form replaces a brick membrane, shortens the foundation construction period, can effectively save the labor force and raw materials particularly for foundations with tight schedules and poor foundation soil qualities, decreases cost and increases benefits, and has good economic benefits and social benefits.

Description

technical field [0001] The invention relates to the field of building formwork, in particular to a prefabricated platform formwork and an installation method thereof. Background technique [0002] In the foundation construction stage of existing buildings, brick tire formwork is widely used in the underground structure to serve as the outer formwork; especially when the foundation cap, foundation beam and bottom plate are integrated, and the supported formwork cannot be removed, brick tire formwork must be used ; In addition, when the slope of the foundation pit is not enough and there is not enough formwork operating surface at the bottom of the foundation pit, brick tire formwork is also required. [0003] The traditional brick formwork construction method is to use blocks to build masonry after the earthwork is excavated to the elevation and the cushion construction is completed, and the inside of the brick formwork is plastered with cement mortar; after the brick wall re...

Problems solved by technology

[0004] The traditional brick formwork wall needs to wait until the masonry shear strength meets the requirements before backfilling and compacting the outer area, which seriously affects the foundation construction process; moreover, when the geological conditions are poor, the brick formwork is prone to collapse phenomenon; in addition, the traditional brick tire formwork masonry method has many disadvantages such as heavy on-site masonry workload, high material consumption, and difficult quality control.
