High-rise residential long-span interval corridor high-altitude formwork steel platform construction method

Abstract

The invention relates to a high-rise residential long-span interval corridor high-altitude formwork steel platform construction method. The construction method includes the following steps: step 1: asteel platform is deep designed and processed; step 2: hoisting and anchoring of a section steel main beam are conducted; step 3: installation of a section steel secondary beam is conducted; step 4: inclined support setting of the section steel main beam is conducted; step 5: plane protection setting is conducted; step 6: external protection frame erection is conducted; step 7: formwork support frame erection is conducted; step 8: beam and slab formwork installation is conducted; step 9: beam and slab reinforcement binding is conducted; step 10: concrete pouring is conducted; step 11: formworkremoval is conducted; step 12: corridor decoration construction is conducted; step 13: peripheral support removal is conducted; and step 14: steel beam removal is conducted. According to the technical scheme, a large-span steel beam is used as a main force-bearing component of a supporting platform, and a certain number of transverse connection steel secondary beams are set among steel beams to form a complete and reliable structural construction formwork steel platform.

Description

technical field [0001] The invention relates to a construction method, in particular to a construction method of a high-altitude formwork steel platform with a large-span interval corridor for high-rise residential buildings, and belongs to the technical field of construction industry. Background technique [0002] With the rapid development of today's domestic economy, people's requirements for living needs have also increased, which has also objectively promoted the rapid construction of residential projects. According to the limited supply of land resources, more and more high-rise residential projects are rapidly rose from the ground. High-rise residences can provide the largest amount of housing supply in a limited area, and as the height of the residence increases, the design of fire escapes becomes more and more important, and its design requirements become more and more stringent. Therefore, in some high-rise buildings In residential buildings, it is inevitable to s...

Problems solved by technology

The height of residential floors is generally about 2.9 meters, and the height of the 12 floors exceeds 30 meters. According to the conventional construction measures of the main structure, it is obviously difficult, long-term, costly and risky to build a formwork support frame body exceeding 30 meters. , and does not have universal operability; therefore, there is an urgent need for a new solution to solve the above technical problems
