Embodiment Construction

[0033] The following examples can enable those skilled in the art to understand the present invention more comprehensively, but the present invention is not limited to the scope of the described examples.

[0034] Such as figure 1 , figure 2 A construction method of a cantilevered steel frame plastic formwork shown specifically includes the following steps:

[0035] S1: tower crane for formwork

[0036] S1.1: Lift the formwork tower to the installation area of ​​the formwork by means of a tower crane. The tower adopts several slings, and the slings pass through a number of through holes matched with the slings set on an iron plate and then connect to the formwork , realize the formwork tower crane.

[0037] S2: Assembly of template:

[0038] S2.1: After the formwork is tower craned to the installation area, assemble the formwork in the installation area according to the drawings. They are hingedly connected to the protective outer frame 4 and the stressed channel steel 2...

Abstract

The invention relates to a cantilever type steel frame plastic formwork construction method, which is characterized by concretely comprising the following steps of tower-craning a formwork, assembling a formwork, installing a formwork structure, and disassembling the formwork structure. Pre-buried ribs are embedded into a concrete dam to be poured, and are connected with stressed channel steel and the concrete dam so as to be used as a support for the whole formwork, and the formwork located below is quickly disassembled through fusing joining positions between the pre-buried ribs and the stressed channel steel so as to be moved upwards to build a reservoir dam above, so that the construction efficiency is improved, and the use of the formwork is saved; and the overall protection rack formwork structure is installed by adopting a way of firstly assembling and then hoisting, so that the installation modularity is realized, the installation efficiency of the overall protection rack formwork is improved, and meanwhile, the installation cost of the formwork is reduced.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a construction method of a cantilevered steel frame plastic formwork. Background technique [0002] The formwork support method of the concrete dam surface occupies a very important proportion to the construction cost and progress of the dam, and is very important to the appearance quality of the dam body. Therefore, choosing the appropriate formwork technology to make the formwork technology easy, labor-saving and fast will play a key role in the construction of the concrete dam. [0003] At present, there are mainly three types of concrete dam face formwork: (1) large-format formwork connected by combined steel formwork, which is installed with direct pull bolts to form a semi-cantilever form; (2) flipped formwork, which is a full-cantilever form; (3) multiple Card template, in full cantilever form. [0004] The semi-cantilever formwork and flip formwork are equipped w...
