Abstract
A kind of charger of FRP-concrete bonding interface sliding test macro, comprise base plate, mobile lifting platform, the hollow jack of double acting, sensor, on base plate, have groove, the hollow jack of double acting upper end is fixed by bolts to and loads on support, its movable end is connected with sensor, the other end of sensor is connected with bolt with stationary barrier, the middle part of stationary barrier is connected with positioning screw, end, positioning screw lower end is connected with chuck, in chuck, be provided with collet, adjusting bolt is equipped with in the both sides of chuck. Can controlled loading speed when manual loading of the present invention and realize intermediate suspension state, be conducive to the collection of load and relative displacement data, avoid the vibration of test specimen and the drift of data; Mobile lifting platform plays the effect of lower chuck simultaneously, allows concrete test block in self-balancing state, facilitates test specimen contraposition and adjustment, can ensure not eccentric simultaneously; Load maintainer is simple, can keep away the precision except the data acquisition being caused by loading vibration.
Description
Technical field
The present invention relates to a kind of charger of FRP-concrete bonding interface sliding test macro.
Background technology
In existing FRP-concrete bonding interface sliding test macro (draw and cut test macro), simple shear test adopts electro-hydraulic servo universal material testing system (CSS-280-100) to carry out pull-out test conventionally, it is simple and convenient that the method seems, but the shortcoming can not be ignored is: because servo adopts hydraulic electric motor control, no matter adopt load or displacement Loading Control, cannot suspend and interrupt in universal testing machine load operating process, cause relation corresponding with certain load in the time of the speckle picture that indirect measurement methods such as utilizing Digital Image Correlation Method is recorded to be difficult to set up, be unfavorable for later stage displacement and strain analysis and data preparation.
Summary of the invention
Object of the present invention is just to provide a kind of be conducive to load and the collection of shuffle data store relatively, can avoid test specimen vibration and data drift, and the precision of data acquisition is high, facilitate the charger of the FRP-concrete bonding interface sliding test macro of test specimen contraposition adjustment simultaneously.
The charger of FRP-concrete bonding interface sliding test macro of the present invention, comprise underframe, base plate, mobile lifting platform, the hollow jack of double acting, sensor, base plate is supported by underframe, mobile lifting platform is arranged on base plate below, on base plate, have groove, pass for test specimen, the top of base plate is provided with loading support, the hollow jack of double acting upper end is fixed by bolts to and loads on support, the lower end of the hollow jack of double acting is connected with sensor upper end, the lower end of sensor is connected with stationary barrier bolt, the middle part of stationary barrier is connected with positioning screw by screw thread, the hollow part of the hollow jack of double acting is run through in the upper end of positioning screw, its end, lower end is threaded with chuck, in chuck, be provided with collet, collet is made up of spring leaf and two briquettings, the spring leaf of collet is connected with the suspension hook in chuck, adjusting bolt is equipped with in the both sides of chuck, adjusting bolt is for two briquettings of extrusion spring chuck.
The use procedure of the charger of FRP-concrete bonding interface sliding test macro of the present invention, test specimen is placed on mobile lifting platform, adjusting mobile lifting platform makes test specimen loading end embedding pasting board enter the groove of base plate, mobile lifting platform enters between two briquettings of collet test specimen embedding pasting board, behind location, tightening adjusting bolt can load by the hollow jack of double acting, after off-test, unclamp adjusting bolt, collet unclamps embedding pasting board under the effect of termination spring leaf, and test specimen is taken out in the decline of mobile lifting platform can carry out lower whorl test.
The charger of FRP-concrete bonding interface sliding test macro of the present invention, can controlled loading speed when manual loading and realize intermediate suspension state, be conducive to the collection of load and relative displacement (slippage) data, avoid the vibration of test specimen and the drift of data; Mobile lifting platform plays the effect of lower chuck simultaneously, allows concrete test block in self-balancing state, facilitates test specimen contraposition and adjustment, can ensure not eccentric simultaneously; Load maintainer is simple, can keep away the precision gathering except the data (signal) that caused by loading vibration.
