Abstract

The invention discloses a large-size bracket reinforced structure. The large-size bracket reinforced structure comprises a large-size bracket, wherein the large-size bracket is located upstream a wall, the large-size bracket is formed in a way that concrete and various reinforcing bars are mixed and poured, the reinforcing bars include a plurality of rows of horizontal parallel longitudinal horizontal tensile bars and bend bars which are located at the outer edge of the contour of the large-size bracket as well as parallel longitudinal constructional reinforcement bars which are perpendicularto the longitudinal horizontal tensile bars and bend bars as well as a plurality of layers of horizontal hooping bars which are located in the large-size bracket and are longitudinally and verticallyarranged in a horizontal direction, the horizontal hooping bars adopt HRB400 steel bars with the diameter of 20 to 25 mm, and the vertical and longitudinal spacing between adjacent horizontal hoopingbars is 1000 to 1500 mm. The structure has the advantages of construction investment saving, convenience in construction, safety and reliability, and reinforcement parameters are optimized, so that the purpose of economic rationality is achieved.

Description

technical field [0001] The invention relates to a large-volume corbel reinforcement structure, which belongs to the technical field of water conservancy and hydropower engineering. . Background technique [0002] In recent years, my country's water conservancy and hydropower projects are changing with each passing day, and the scale of the project is also expanding. Due to the needs of structural layout, some hydraulic structures will inevitably have some cantilever structures with long spans and large cross-sectional dimensions. Large-volume corbels are more common One type, its structural reinforcement arrangement is also an important and difficult point in engineering technology research. First of all, for large-volume corbels with little load effect, the structural reinforcement calculation is carried out according to the "Code for Design of Hydraulic Concrete Structures" (DL / T5057-2009, hereinafter referred to as "the specification"), and the calculated longitudinal hor...
