Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] combine Figure 1-3 As shown, a multifunctional structural test loading system that takes into account the loading tonnage and loading accuracy includes a vertical loading component that can vertically load the test model 14, and also includes a main frame, and the vertical loading component is matched with the main frame. The main frame includes a fixed lateral main seat 4, a bottom reaction force base 2 with a plurality of anchor holes 12, and a plurality of anchors that can lock the test model 14 on the bottom reaction force base 2. The hole 12 matches the prestressed anchor component 13.

[0021] The system also includes a top steel reaction force platform 1 directly above the test model 14 , and the top steel reaction force platform 1 is vertically slidably mounted on the lateral main base 4 .

[0022] The above-mentioned vertical loading ...

Abstract

The invention discloses a multifunctional structure test loading system incorporating loading tonnage and loading accuracy in the technical field of civil engineering. The system includes an upright loading component and a main body frame, and further includes a plurality of pre-stressed anchoring assemblies that can lock a test model on a bottom reaction force base; the system further includes atop steel reaction force platform; the upright loading component includes at least four vertical loading climbing actuators; a plurality of X direction slide guides are arranged on the lower surface of the top steel reaction force platform; a plurality of sliders slidably arranged on the X direction slide guides are further distributed on the lower surface of the top steel reaction force platform;a Y direction slide guide arranged vertically in a staggered manner in space with the the X direction slide guides is installed on each slider; and a vertical loading actuator which is capable of performing vertical double-direction loading on the test model and in slidable cooperation with the corresponding Y direction slide guide is installed on each slider. The loading accuracy, application scope and use efficiency of the structure test loading system are significantly improved.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a multifunctional structural test loading system that takes both loading tonnage and loading accuracy into consideration. Background technique [0002] Structural test technology is one of the important foundations to promote the development of civil engineering disciplines. With the rapid development of my country's social economy, a large number of high, large, special and heavy civil engineering structures have been built one after another. These structural systems are novel, complex in force, difficult in design, and have no existing codes for reference. Their mechanical performance urgently needs to be clarified through structural tests, especially large-scale and multi-dimensional model tests. At the same time, with the continuous improvement of the research level of civil engineering in my country, a large number of major scientific problems that have long plagu...
