Top-down method formwork construction process

Abstract

The invention discloses a top-down method formwork construction process. The top-down method formwork construction process specifically comprises the following steps of step 1, surveying a line; step 2, building a formwork supporting system; step 3, installing a beam platform and a plate platform formwork; step 4, installing a column formwork; step 5, installing a wall formwork, and step 6, installing a stair formwork. According to the top-down method formwork construction process, working faces of a woodworker and a steel bender are intersected to synchronously carry out respective operations, process arrangement is compact, the woodworker and the steel bender can continuously operate without downtime, the construction speed is high; and then the column formwork and the wall formwork are sealed, the working face of stirrup binding in beam-column joint is sufficient, and quality of the stirrup binding in the beam-column joint part is guaranteed; one-time concrete integral concreting can be adopted, so that setting-up of horizontal construction joints is reduced; when the woodworker is in operation, sawdust and rubbish left by beams and plates can be cleaned by a blower in time, it is guaranteed that no sundries are retained in the formwork during rebar binding, and concrete concreting quality is improved.

Description

technical field [0001] The invention relates to the field of construction, in particular to a formwork construction technology of the reverse method. Background technique [0002] With the great development of construction in various parts of our country, construction engineering has become a popular industry again. Building materials are the basis of construction engineering. Building materials can be divided into structural materials, decorative materials and some special materials. Structural materials include wood, bamboo, stone, cement, concrete, metal, bricks, ceramics, glass, engineering plastics, composite materials, etc.; decorative materials include various coatings, paints, coatings, veneers, tiles of various colors, and special effects Glass, etc.; special materials refer to waterproof, moisture-proof, anti-corrosion, fire-proof, flame-retardant, sound insulation, heat insulation, heat preservation, sealing, etc. [0003] The concrete structure in the building n...

Problems solved by technology

[0003] The concrete structure in the building needs to achieve the effect of fair-faced concrete. The selection of the formwork system is related to the construction progress of this project and the key to the realization of the quality level goal of the "high-quality main body" of the structure. The existing formwork system is installed. Continuous construction is not possible, the work efficiency is slow, it takes a long time, and there are sundries in the formwork, which will affect the quality of subsequent concrete pouring, which brings inconvenience to people
