Embodiment Construction

[0031] The present invention is further described below in conjunction with embodiment:

[0032] A formwork construction method for a high-altitude large-span cantilevered steel platform, comprising the following steps:

[0033] 1. Construction preparation

[0034] Complete the in-depth design before construction, select suppliers of various materials, prepare construction equipment and other related materials, and organize construction technical workers to make technical disclosures.

[0035] 2. Construction of embedded parts

[0036] 1. The embedded part of the diagonal brace base: it is pre-embedded in the reinforced concrete main beam of the lower layer of the overhanging layer, and the iron plate of the embedded part and the anchor bar are welded and connected in the processing plant, and the weld seam is full. The embedded parts of the diagonal brace base include steel plates and steel bars, the steel plates are welded to the section steel, and the steel bars are welde...

Abstract

The invention discloses a construction method of a high altitude large-span overhanging steel platform formwork. The construction method includes the steps of preparation of construction, construction of embedded parts, installation of primary beam, installation of a large corner single truss, installation of a bracing piece, installation of a secondary beam, laying of a steel plate, welding of an outer frame anti-skid positioning pile, building of an outer frame, installation of a cable-stayed bar, removing and the like. By adoption of the construction method, the construction problem of a structure-complex special-shaped large-span high altitude overhanging structure of hanging garden layer is solved successfully. Machining is simple, the construction is simple and convenient, the safety factor is high, the construction efficiency is high, the influence to a construction working face is extremely low, the influence to the construction period is low, the installation and removing construction are simple and convenient, materials can be repeatedly used for circulation, and the requirement for environmental-protection construction is met.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a construction method suitable for high-altitude and large-span cantilever structures of industrial and civil buildings. Background technique [0002] In recent years, high-altitude and large overhangs are often used in modern architectural design to meet the needs of functional and beautiful appearance. In the middle and top of the towers of public buildings and super high-rise commercial and residential buildings, in order to achieve the architectural effect of openness, transparency and wide vision, sometimes a multi-storey atrium is set up; A cantilever structure that cantilever several meters outside the building plane will be set up to highlight the unique shape and majestic charm of the building. [0003] However, the high-altitude long-span cantilevered steel platform formwork has the characteristics of large span, high height, heavy construction load, and high const...
