Embodiment 1

[0027] The high-altitude cantilever structure formwork support and the construction method of the upper protection system of the present invention comprise the following steps:

[0028] a. Position, install embedded parts and leave connecting bolts in advance along with the main structure (on the second floor and the next floor) during construction.

[0029] figure 1 It is a structural schematic diagram of the high-altitude cantilevered structure formwork support and the upper protection system according to the embodiment of the present invention. The pre-embedded part of the double-tensioned steel plate is used, and it is factory-processed according to the width of the beam by connecting four opposite-tensioned bars (the embedded part includes the connecting bolts as a whole). Accurate positioning is carried out according to the special construction plan, and the review is strengthened to ensure that the position of the pre-embedded part is accurate. .

[0030] b. Install t...

Abstract

The invention discloses a high-altitude cantilever structure formwork support and an upper protection system construction method. The high-altitude cantilever structure formwork support and the upper protection system construction method is characterized by comprising the following steps that a, construction positioning is conducted in advance along with a building main body structure, embedded parts are installed, and connecting bolts are reserved; b, cantilever girders and lower inclined struts are installed; c, the support bottom is closed; d, a high-altitude cantilever structure formwork support body is erected; e, acceptance and concrete pouring are conducted; and f, edge protection construction is conducted before modeling construction of an inclined roof on the upper portion of a roof, vertical rods on the outer side continue to be heightened in a staggered mode, the vertical rods on the outer side are connected with newly-added vertical rods above a cornice into a whole, temporary tying is conducted, and it is guaranteed that a protection system is stable and reliable. The high-altitude cantilever structure formwork support and the upper protection system construction method have the advantages that the problems that a high-altitude cantilever structure formwork support system cannot take roots and exert force, and a reliable safety protection system cannot be arranged in upper roof modeling construction are solved, and a large amount of profile steel is not needed; and factory processing is adopted, installation is convenient and fast, turnover use can be achieved, and quality guarantee and construction safety are achieved.

Description

technical field [0001] The invention relates to a formwork system for a high-altitude cantilevered structure, in particular to a construction method for a high-altitude cantilevered structure formwork support and an upper protection system. Background technique [0002] The formwork support and upper protection system of the high-altitude cantilevered structure must bear all the loads transmitted during the formwork installation and concrete pouring during the construction process. It is not only an operating platform, but also a safety protection facility, and it is also a various load bearing system. The safety of the formwork support system is an important part of building construction safety, and it also belongs to the more dangerous sub-item projects exceeding a certain scale in building construction. The main and biggest hazards of using the formwork support system are overall instability, collapse and overturning. It is necessary to ensure that the frame supports the...
