Adjustable three-dimensional loading test system for reinforced concrete members of different sizes and shapes

Abstract

The invention relates to a combined adjustable three-dimensional loading test system applicable to steel concrete members of different sizes and shapes, comprising an assembled base, on which is provided a circular shape that can move along the left and right directions of the assembled base Structure I, there are three return-shaped structures II inside the return-shaped structure I, wherein the return-shaped structure II in the middle is fixed, and the return-shaped structures II on both sides can be assembled along the The type base moves forward and backward; a lifting test platform is arranged in the space surrounded by three back-shaped structures II, and a rear loading oil cylinder for loading the rear part of the reinforced concrete member is provided on the said back-shaped structure I. Said return-shaped structure II is provided with a side loading oil cylinder and an upper loading oil cylinder for loading the side and top of the reinforced concrete member; the loading oil cylinder is pushed and fixed by a moving fixing device.

Description

technical field [0001] The invention relates to a combined adjustable three-dimensional loading test system applicable to steel concrete members of different sizes and shapes. [0002] technical background [0003] At present, a large number of steel concrete components are used in various projects. In order to meet the needs of different projects, it is necessary to make steel concrete components of different sizes and shapes; in order to ensure the quality and safety of the project, the physical and mechanical parameters of the steel concrete components need to be measured in detail. Reinforced concrete members are required for loading tests. Since steel concrete components have the characteristics of variable size and shape, uncertain loading position, and relatively large yield and failure loads, the loading test of steel concrete components must have large tonnage, high strength, flexible and adjustable loading position, and be suitable for various The shape of the comp...

Problems solved by technology

[0004] Chinese patent ZL201010546650.8 invented a fatigue loading durability test device for steel concrete components. It is more suitable for plate-type reinforced concrete components, and the size cannot be adjusted, so the versatility is poor

[0009] 1) The test device has poor versatility, and the position of the loading frame and the position of the loading cylinder cannot be adjusted arbitrarily according to the shape and size of the steel concrete member;

[0010] 2) The structure of the test device is not compact, the loading space and loading tonnage are small, and the loading test of large-size, large-tonnage, and high-strength steel concrete components cannot be carried out;

[0011] 3) The loading test device cannot achieve self-balancing, and the loading frame cannot be automatically controlled to move and lock. It is inconvenient to install and use, and the flexibility is poor
