Embodiment 1

[0037] The construction technology of the simply supported beam method cantilevered corridor formwork support system provided in this embodiment includes the following steps:

[0038] (1) Pre-embedded cantilevered I-beam pressure ring

[0039] The pressure ring is pre-embedded in advance on the floor where the cantilevered I-beam needs to be supported, and the diameter of the U-shaped steel bar pull ring is 16mm.

[0040] (2) Selection and welding of simply supported I-beam

[0041] According to the drawings and design requirements, two 20a# I-beams of sufficient length are selected to be stacked as simply supported I-beams, and the two I-beams are welded firmly to form a whole.

[0042] (3) Simply supported I-beam hoisting

[0043] Use the tower crane to hoist the welded I-beam to the floor where the cantilevered I-beam needs to be erected and fix it. The length of overlap with the structure is 400mm to ensure the overall stability of the simply supported I-beam.

Abstract

The invention discloses a simply-supported beam method cantilever connecting corridor formwork support system construction technology. The technology comprises the following steps of cantilever I-shaped steel compression ring embedding, simply-supported I-shaped steel selecting and welding, simply-supported I-shaped steel hoisting, cantilever I-shaped steel hoisting, formwork support system building, rebar installing, concrete pouring and simply-supported beam formwork support system dismantling. According to the simply-supported beam method cantilever connecting corridor formwork support system construction technology, the support system cantilever length is reduced, the torque is reduced, and therefore the frame cantilever length is reduced to support the loaded formwork support system.

Description

technical field [0001] The invention relates to a construction technique for a formwork support system of a cantilevered corridor with a simply supported beam method, and belongs to the technical field of building construction. Background technique [0002] In recent years, fire-fighting corridors are generally installed in high-rise and super-high-rise buildings to meet fire protection requirements. Usually, the fire-fighting corridors are close to the buildings so that the overhang length of the formwork support system is small. With the various changes in the design, fire-fighting corridors far away from the building have also begun to appear, and there is a certain degree of difficulty in the construction of the formwork support system with a large cantilever distance. Therefore, it is necessary to develop a fire-fighting corridor formwork support system suitable for such situations. Contents of the invention [0003] The technical problem to be solved by the present ...
