Abstract

A kind of charger of FRP-concrete bonding interface sliding test macro, comprise base plate, mobile lifting platform, double acting hollow jack, sensor, base plate has groove, double acting hollow jack 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 stationary barrier bolt, the middle part of stationary barrier is connected with positioning screw, positioning screw lower end is connected with chuck, be provided with collet chuck in chuck, adjusting bolt is equipped with in the both sides of chuck.Can controlled loading speed and realize intermediate suspension state during the utility model manual loading, 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 be in self-equilibrating state, facilitates test specimen contraposition and adjustment, can ensure not eccentric simultaneously; Load maintainer is simple, can keep away the precision except being vibrated the data acquisition caused by loading.

Description

The charger of FRP-concrete bonding interface sliding test macro
Technical field
The utility model 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 usually, the method seems simple and convenient, but the shortcoming that can not be ignored is: because servo adopts hydraulic electric motor to control, no matter adopt load or displacement Loading Control, cannot suspend in universal testing machine load operating process and interrupt, the relation corresponding with certain load when the speckle picture that indirect measurement methods such as utilizing Digital Image Correlation Method is recorded is caused to be difficult to set up, be unfavorable for later stage displacement and strain analysis and data preparation.
Summary of the invention
The purpose of this utility model is just to provide a kind of collection being conducive to load and Relative sliding data, test specimen can be avoided to vibrate and data wander, and the precision of data acquisition is high, the charger of the FRP-concrete bonding interface sliding test macro simultaneously facilitating test specimen contraposition to adjust.
The charger of FRP-concrete bonding interface sliding test macro of the present utility model, comprise underframe, base plate, mobile lifting platform, double acting hollow jack, sensor, base plate is by underframe support, mobile lifting platform is arranged on below base plate, base plate has groove, pass for test specimen, the top of base plate is provided with loading support, double acting hollow jack upper end is fixed by bolts to and loads on support, the lower end of double acting hollow jack 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 double acting hollow jack is run through in the upper end of positioning screw, its lower end is threaded with chuck, collet chuck is provided with in chuck, collet chuck is made up of spring leaf and two pieces of briquettings, the spring leaf of collet chuck is connected with the suspension hook in chuck, adjusting bolt is equipped with in the both sides of chuck, adjusting bolt is used for two pieces of briquettings of extrusion spring chuck.
The use procedure of the charger of FRP-concrete bonding interface sliding test macro of the present utility model, test specimen is placed on mobile lifting platform, adjustment mobile lifting platform makes the embedding pasting board of test specimen loading end enter the groove of base plate, mobile lifting platform makes the embedding pasting board of test specimen enter between two pieces of briquettings of collet chuck, tighten adjusting bolt behind location namely to load by double acting hollow jack, adjusting bolt is unclamped after off-test, collet chuck 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 utility model, can controlled loading speed and realize intermediate suspension state during manual loading, 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 be in self-equilibrating state, facilitates test specimen contraposition and adjustment, can ensure not eccentric simultaneously; Load maintainer is simple, can keep away the precision except the data (signal) caused by loading vibration gather.
