AI Technical Summary
Technical Problem
The lack of easily adjustable, highly applicable, expandable and reusable lateral restraint devices in existing structural tests has led to frequent out-of-plane instability problems of components.
Method used
An assembled adjustable lateral constraint device was designed, including an adjustable-length crossbeam and horizontal and diagonal support rods. The length and angle of the support rods are adjusted by bolt connection and roller structure, which is suitable for test components of different sizes and types.
Benefits of technology
It enables easy adjustment of the support rod length and angle, prevents out-of-plane instability of the test component, improves the accuracy and reusability of the test, and reduces friction error.

Abstract
本发明公开了一种用于结构试验的装配式可调节侧向约束装置。结构的拟静力试验是目前研究结构或结构构件受力及变形性能时应用最广泛的方法之一。本发明包括横梁，所述横梁两端水平夹持固定于反力架立柱翼缘之间，横梁长度可调节；所述横梁上固定连接有水平支撑杆，水平支撑杆长度可调节；所述横梁上转动连接有斜向支撑杆，所述斜向支撑杆长度、角度可调节。本发明调节简便，可以在不拆卸的情况下调节支撑杆长度及角度，便于不同尺寸的试件试验；具有较大的承载能力，可有效防止试验试件发生平面外失稳。
