Embodiment Construction

[0048] Such as Figure 1-11 Among them, a hydraulic self-elevating cantilever heavy-duty arch dam formwork platform, the self-climbing formwork system is provided with multi-layer platforms for construction from top to bottom, and each layer of platforms is connected to the self-climbing formwork system through platform leveling rods 106 , to level the platform. Due to this structure, during the construction process, it is convenient to keep the platform in a horizontal state all the time, so that construction equipment can be placed conveniently, construction operations can be facilitated, and construction safety can be ensured.

[0049] The preferred solution is as figure 1 , 2 In the self-climbing formwork system, the first platform 13, the second platform 14, the third platform 19 and the fourth platform 11 are arranged sequentially from top to bottom;

[0050] The first platform 13 is located on the top of the formwork device 10; it is used for pouring and formwork co...

Abstract

The invention provides a hydraulic self-lifting cantilever heavy arch dam template work platform. Multiple layers of platforms for construction are arranged at a self-climbing template system from top to bottom; each layer of platform is connected with the self-climbing template system through a platform leveling pull rod so as to be used for regulating the platform into a horizontal state. By using a structure of the platforms capable of being leveled, the corresponding horizontal state regulation of the work platform along with the incline of the an arch dam by the work platform of a self-lifting cantilever heavy arch dam template system can be ensured, so that construction personnel are always in a horizontal operation state; the relevant auxiliary construction equipment is always in the horizontal state, so that the construction efficiency is improved; the construction safety is ensured.

Description

technical field [0001] The invention relates to an arch dam construction template, in particular to a hydraulic self-elevating cantilever heavy-duty arch dam template working platform. Background technique [0002] For a long time, the formwork used for concrete pouring of arch dams has been a crane-lifted common dam formwork. Under normal construction conditions, this formwork system can meet the construction requirements of arch dam concrete. However, once the arch dam is in a perennially windy environment or the lifting means are insufficient, the construction safety and construction efficiency of ordinary dam formwork will greatly affect the arch dam concrete construction work. The self-climbing dam formwork technology can well solve the above-mentioned problems of common dam formwork. However, during the climbing process, the automatic climbing formwork technology requires the formwork slab surface to be separated from the concrete surface by a certain distance (about ...
