Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] see figure 1 and image 3 , a prestressed reinforced concrete cast-in-place steam turbine generator base in this embodiment includes a base plate 5, a frame column 2 and a frame beam 3, and is set in the base plate 5, frame column 2 and frame beam 3 There are prestressed steel bars 1 stretched by post-tensioning method, and prestressed steel bars 1 are unbonded prestressed steel bars.

[0019] The two ends of the prestressed steel bar 1 are respectively anchored to the ends of the base floor 5 , the frame column 2 or the frame beam 3 by tension-end anchors and fixed-end anchors.

[0020] The anchorage at the tension end adopts the existing Type I clip-type anchorage, see Figure 4 , The clip-type anchor is mainly composed of clip, anchor ring I6, anchor pad I7 and spiral rib I8.

[0021] The anchorage at the fixed end adopt...

Abstract

The invention discloses a prestressed reinforced concrete cast-in-place turbine generator base which comprises a base bottom plate, frame columns and frame beams. Prestressed reinforcements tensioned through a post-tensioning method are arranged in the base bottom plate, the frame columns and the frame beams. The two ends of each prestressed reinforcement are anchored at the ends of the base bottom plate or the corresponding frame column or the corresponding frame beam through a tensioned end anchorage device and a fixed end anchorage device. A cavity mold is reserved at the end of the base bottom plate or the corresponding frame column or the corresponding frame beam where each tensioned end anchorage device is located, and the tensioned end anchorage devices are fixed into the reserved cavity mold. Unbounded prestressed reinforcements are adopted as the prestressed reinforcements. The prestressed reinforcements tensioned through the post-tensioning method are arranged in all the components of the turbine generator base, and compared with a common turbine generator base, the turbine generator base has the beneficial effects of being high in integral rigidity, small in overall deformation, small in base vibration and short in production period and reducing cost.

Description

technical field [0001] The invention relates to a prestressed reinforced concrete cast-in-situ steam turbine generator base. Background technique [0002] At present, the general steam turbine base adopts cast-in-place reinforced concrete frame structure, but in order to control the vibration of the base, it is necessary to add a large amount of counterweight to increase the stiffness and weight of the base, which consumes a large amount of steel and concrete materials, and the cost is very high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a prestressed reinforced concrete cast-in-situ steam turbine generator base to solve the problems existing in the prior art. [0004] In order to solve the problems of the technologies described above, the present invention adopts the following technical solutions: [0005] A prestressed reinforced concrete cast-in-situ steam turbine generator foundation includes a foundat...
