Cast-in-place concrete early-dismantling formwork system and construction method thereof

Abstract

The invention discloses a cast-in-place concrete early-dismantling formwork system and a construction method thereof. The construction method comprises the steps of installing beam and slab supportingstructures, installing a beam and slab formwork, installing floor supporting structures, assembling a floor formwork and the like. The construction method of the cast-in-place concrete early-dismantling formwork system can achieve early dismantling in the real sense, and the allocation amount of the formworks is reduced by 1/3 to 1/2. The jacking and supporting combination degree is high, installation and disassembly are easy, the stability is high, and the bearing capacity is high. The height of the floor formwork and the height of the beam and slab formwork can be adjusted to meet differentconstruction requirements. Besides, much fewer wood rods, much fewer steel pipes and much fewer wood beams are used, fewer building wastes are generated, the construction environment is clean, neat,beautiful and friendly, it is ensured that the site is cleaned up after construction is finished, and potential safety hazards to workers are reduced. The input cost is reduced, resource waste is reduced, and the construction method of the cast-in-place concrete early-dismantling formwork system has an important significance in energy saving, environmental protection, low carbon and emission reduction.

Description

technical field [0001] The invention relates to a building formwork support system, in particular to a cast-in-place concrete early demolition formwork system and a construction method thereof. Background technique [0002] At present, building construction basically adopts cast-in-place concrete structure engineering construction, and the building formwork structure used for construction is mainly composed of three parts: panels, support structures and connectors. The panel is a load-bearing slab that directly contacts the cast-in-place concrete; the support structure is a temporary structure that supports the panel, concrete and construction loads, ensuring that the building formwork structure is firmly combined without deformation or damage; the connector is the connection between the panel and the support Fittings that connect structures into a whole. [0003] At present, wooden formwork is usually used as the panel, and the supporting structure is generally connected b...
