Gliding resistant foundation structure

Abstract

The invention discloses an anti-sliding foundation structure. An anti-sliding toe (2) is made of armor plate; the upper part of the anti-sliding toe penetrates deeply into a foundation base (1), and the lower part is inserted in the foundation of the base. In order to fixedly combine the anti-sliding toe with the foundation base, the upper part of the anti-sliding toe (2) is provided with a bent segment (3). In order to improve the anti-sliding ability, the invention can adopt the following proposals: the upper part of the anti-sliding toe (2) is shortened, the top is provided with the armor plate (4), and the armor plate (4) is provided with anchor reinforcing steel bars (5). The foundation bottom surface is added and provided with the embedded armor plate anti-sliding toe, so that the invention can not only effectively increase the anti-sliding ability of the foundation to reduce the amount of foundation concrete but also greatly improve the anti-sliding reliability of the foundation to ensure the design to be more economic and reasonable as the armor plate anti-sliding toe is fixedly combined with the foundation base.

Description

technical field [0001] The invention relates to a building foundation structure, in particular to an anti-sliding foundation structure. Background technique [0002] With the development of building technology today, new building structure types are constantly emerging. The arched grid structure that has appeared in recent years has attracted more and more attention because of its large span, no internal columns, and fast construction. However, when this type of structure is adopted, the horizontal thrust acting on the top surface of the foundation is also much larger than the traditional structure due to its structural characteristics. In order to ensure the anti-slip capability of the foundation, the traditional structure is adopted in the prior art, as shown in Figure 4; the other is a structure with an anti-slip toe that the applicant applied for in October 2006, such as Figure 5 shows. [0003] For the traditional foundation mechanism, as shown in Figure 4, its effect...

Problems solved by technology

The traditional foundation mechanism is to increase the self-weight of the foundation to increase the value of Gμ, but the increase in self-weight has caused a lot of waste of concrete; for the foundation structure with an anti-slip toe, as shown in Figure 5, the soil on the bottom surface of the foundation will be The anti-slip toe produces a force that is opposite to the horizontal thrust of the base top, that is, P, and the resultant force of the horizontal thrust becomes (E at -P), obviously, after the denominator horizontal thrust is reduced, the anti-sliding ability of the foundation has been significantly improved, but since the anti-sliding toe is still made of concrete, its joint with the concrete bottom is not firm, It is easy to crack or even break, thereby reducing the anti-slip ability of the foundation
