Embodiment Construction

[0026] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only for explaining the present invention, and are not intended to limit the scope of the present invention.

[0027] see figure 1 , a cup base support column installation structure, including a cup base 1 and a support column 2, a grouting material 3 is poured between the cup base 1 and the support column 2, and the cup base 1 is provided with a cup insert 4. The cup opening rib 4 passes through the cup opening foundation 1 and connects with the support column 2 .

[0028] In this structure, the cup mouth insertion rib 4 is provided in the cup mouth foundation 1, so that the ability to resist the pull-out force on the support column 2 is greatly improved. At the same time, because the cup mouth insert rib 4 is used to transmit the tension of the support column 2, the force is clear, quantitative calculation can be realized,...

Abstract

The invention discloses a mounting structure for a cup foundation and a support column and a construction method. The mounting structure comprises the cup foundation and the support column. A grouting material is poured in the position between the cup foundation and the support column. A cup inserting rib is arranged in the cup foundation and penetrates out of the cup foundation to be connected with the support column. The problem that the capacity, for resisting the uplift force of a support column, of a cup foundation in the prior art is insufficient is solved. The cup inserting rib is used for transferring the tension of the support column, stress is clear, and the capacity for resisting the uplift force of the support column is greatly improved.

Description

technical field [0001] The invention relates to the technical field of civil engineering, relates to a cup opening foundation support column installation structure, and also relates to a construction method based on the cup opening foundation support column installation structure. Background technique [0002] The mechanical characteristics of foundations such as power transmission towers and herringbone column substation frames are: small vertical loads and large horizontal loads. In the design, the foundation with strong anti-overturning ability, large horizontal load and resistance to uplift force should be used first. [0003] At present, the substation structure generally adopts the herringbone column structure, and the existing herringbone column frame foundation mainly adopts the cup foundation and the flange foundation, and the connection methods of the two foundations and the support column also have their own shortcomings. [0004] The flange foundation requires b...
