Description
Technical field
The utility model relates to the concrete cracking measuring technology, and particularly a kind of circular ring type is induced accelerate concrete split test device.
Background technology
The concrete works crack is modal to be the contraction fissure that causes and the load crack of being caused by the external loads effect because concrete self drawdown deformation suffers restraints.The cracking problem that is caused by contraction is having a strong impact on the safety and durability of concrete works, in order in building construction, better to avoid the appearance of crackle, need carry out accurately quantitative test to concrete cracking resistance, and then eliminate cracking hidden danger in the design in the early stage.In the existing measuring technology, can early detect crackle at the stress concentrated position by non-circular ring type device, but inhomogeneous because cracking being sentenced outer position constraint, be difficult to reflect concrete cracking resistance comprehensively; Though do not provide even constraint and there is the induction type circle ring device, cracking time is long, and crackle the position occurs at random, also is unfavorable for making the evaluation to crack-resistant performance of concrete.
Summary of the invention
The purpose of this utility model is to provide a kind of circular ring type to induce accelerate concrete split test device, and this device can quick and precisely test out cracking time and the cracking position of concrete sample, and then concrete cracking resistance is made an appraisal.
For achieving the above object, the utility model is achieved by the following technical solutions.
A kind of circular ring type is induced accelerate concrete split test device, it is characterized in that, comprise base, suit fixedly has inner ring sleeve and outer ring set on the described base, looping space between described inner ring sleeve and the described outer ring set, circumferentially be evenly equipped with stress induced generator on the inwall of described outer ring set, the outer wall of described outer ring set is provided with the handle of symmetry.
Characteristics of the present utility model and further the improvement are:
(1) described inner ring sleeve is concentric suit with described outer ring set, and described outer ring set is connected by two semi-ring covers and forms, and an end of described two semi-rings connects by hinge, and the other end connects by bolt.The characteristics of the technical program and further the improvement are:
(a) described outer ring set is fixed on the described base by four circumferential outer ring set gib screws.
(b) described inner ring sleeve is fixed on the described base by four circumferential inner ring sleeve gib screws.
(2) described stress induced generator is uniform four angle steel that are welded on the described outer ring set inwall.
(3) post foil gauge on the outer wall of described inner ring sleeve.
A kind of circular ring type of the present utility model is induced accelerate concrete split test device, comprise base, suit fixedly has inner ring sleeve and outer ring set on the described base, looping space between described inner ring sleeve and the described outer ring set, circumferentially be evenly equipped with stress induced generator on the inwall of described outer ring set, the outer wall of described outer ring set is provided with the handle of symmetry; During test, spray release agent on the inwall of ring set outside earlier, install inner ring sleeve and outer ring set, again with the concreting of suitable match ratio in annular space, after the stipulated time, catch handle, take off outer ring set, concrete sample is positioned over maintenance in the prerequisite, observe the crackle time of occurrence; This utility model can quick and precisely test out cracking time and the cracking position of concrete sample, and then concrete cracking resistance is made an appraisal.
