Slidable stringer for top formwork platform and its construction method

Abstract

The invention provides a slidable tumbling barrel used for a top formwork platform and a construction method thereof. The slidable tumbling barrel comprises two slide rails and a positioning mechanism on the top formwork platform. Each slide rail is provided with an inner side opposite to the other slide rail and an outer side away from the other slide rail. The positioning mechanism is provided with multiple pull hooks which are arranged on the outer sides of the slide rails in a paired mode. A slide seat is arranged on the two slide rails and provided with a hanging opening which is used for clamping and hanging a tumbling barrel body, the tumbling barrel body is hung under the slide seat and is adjusted along with sliding of the slide seat, and the slide seat is hooked by the corresponding paired pull hooks to be positioned. The top formwork platform is provided with the slide rails, the positioning mechanism and the slide seat, after the tumbling barrel body is hung on the slide seat, long-distance sliding distribution can be achieved, and the technical effects of expanding the distribution range, reducing the number of tumbling barrels and construction cost and reducing the dead weight of the top formwork platform are achieved.

Description

technical field [0001] The invention relates to the technical field of pouring of super high-rise buildings, in particular to a string tube used for a top form platform and a construction method thereof. Background technique [0002] With the continuous construction of super high-rise buildings, new formworks are also continuously derived. In recent years, the top formwork system has become the main formwork system choice in the construction of super high-rise buildings. However, there are many floors under the top formwork system, and the concrete pump pipe can only pour the concrete of the core tube wall through the distributor installed on the top of the top formwork platform; pregnancy. [0003] The stringing tube refers to a tube-shaped object set up to prevent segregation of concrete during the vertical conveying of concrete, and is used to make the concrete slide down through the stringing tube. It is worth noting that the pouring range of the string tubes is only a...

Problems solved by technology

[0004] In view of the foregoing, the present invention provides a slidable stringer for a top mold platform and a construction method thereof, by setting a sliding device for hanging the stringer on the formwork platform, so that the stringer passes through the sliding device It realizes long-distance material distribution by sliding on the top form platform, and solves the problem of high cost caused by the need to set a large number of fixed stringers on the top form platform to complete concrete pouring and the substantial increase in the weight of the top form platform due to the stringing of the tubes. problem, to achieve beneficial technical effects such as increasing the cloth range of stringing tubes, reducing the number of stringing tubes, and reducing the self-weight of the top mold platform
