Problems solved by technology

In the general design, the tensile performance of the anchored concrete structure is increased by increasing the use of the anchored steel structure of the reaction frame, increasing the buried depth, and laying multiple layers of steel plates on the anchored concrete structure, but this also results in a low material utilization rate. , huge structure and poor economy

Abstract

The invention discloses a system and method of enhancing the tensile property of a ground-counter reaction rack. The system comprises an anchoring steel structure, an anchoring concrete structure and an enhanced twisted steel prestress system. An operating method successively comprises the following steps of: bolting and welding the anchoring steel structure; mounting the enhanced twisted steel prestress system; pouring concrete of the anchoring concrete structure; tensioning the prestressed twisted steel; and performing anchoring. The impact effect of arranging the enhanced twisted steel prestress system on the maximum principal stress of the lower anchor concrete structure under the maximum design load is compared and analyzed by means of finite element calculation. The system and method disclosed by the invention have the beneficial effects that the prestress anchoring system is used in an anchoring structural design of the ground-counter reaction rack, so that the stress characteristic of the anchoring concrete structure is optimized, the tensile stress of the anchoring concrete structure is remarkably reduced, the tensile property of the ground-counter reaction rack is enhanced, and the safety coefficient of the structure is increased; the use level of a material of the anchoring steel structure is reduced, the using efficiency of the material is fully exerted, and the economical benefit is good.

Description

technical field [0001] The invention relates to the field of structural design of a ground anti-reaction frame, in particular a system and method for enhancing the tensile performance of a ground anti-reaction frame. Background technique [0002] The reaction frame is often used for calibration and verification of jacks, and is also used for tensile and compressive performance tests of concrete structures and steel structures. Experimental testing institutions and scientific research institutes of universities are generally equipped as routine testing and testing instruments. There are two main structural forms of commonly used reaction frames: self-reflective and ground-trans. The self-reflection reaction frame achieves the effect by providing reaction force by itself, and the ground reaction reaction frame mainly acts on the anchored concrete structure with good anchoring effect to provide reaction force, so the reaction frame and the foundation are in good condition.
