Description
Technical field
The utility model relates to a kind of Automatic continuous test concrete limited expansion rate device.
Background technology
Cement expansive material is a kind of jointless construction that is widely used in super-long structural, underground concrete structure is from waterproof, the additive of preparation expansive concrete, in production and use procedure for swelling agent, it is particularly important testing concrete limited expansion rate, concrete limited expansion rate is an important indicator evaluating swelling agent quality, in < < GB23439-2009 cement expansive material > >, recommended concrete test device and method, it is mainly by the length variations of test limits expansion rod, to characterize the effect of swelling agent, utilize the length of comparator manual test confined expansion bar, because needing testing crew, the method manually measures, on the one hand, the expansivity of test is long interval time, cannot monitor continuously, on the other hand, be easy to be subject to the test error that human factor causes, measuring accuracy is difficult to guarantee.
Summary of the invention
The utility model object is for above-mentioned present situation, aims to provide a kind ofly can automatically gather the time dependent trend of concrete expansion rate the Automatic continuous test concrete limited expansion rate device that test accuracy is high, time saving and energy saving.
The implementation of the utility model object is: a kind of Automatic continuous test concrete limited expansion rate device, confined expansion bar two ends are fixed on steel plate, magnetic stand one, magnetic stand two and magnetic switch are fixed on the steel plate of confined expansion bar two ends, threaded rod one end is threaded with magnetic stand one, the square contact jaw of one end contacts with displacement clock gauge, displacement clock gauge gauge outfit withstands on the square termination of threaded rod, displacement clock gauge is threaded with magnetic stand two, and is fixed by the nut that injects magnetic stand two.
While using the utility model, confined expansion bar in utility model is put into concrete test die moulding together, form removal after concrete reaches strength of mould stripping, by the concrete confined expansion test block two ends steel plate scrub of form removal, then by magnetic stand one, magnetic stand two is fixed on the steel plate at confined expansion bar two ends by confined expansion bar two ends magnetic switch, by threaded rod thread end be screwed into Magnetic gauge stand with internal thread hole in, displacement clock gauge is inserted in Magnetic gauge stand two, and guarantee that displacement clock gauge gauge outfit withstands on the square contact jaw contact of threaded rod, displacement clock gauge gauge outfit withstands on the termination of threaded rod.By upper end nut, fix, concrete sample is put under the maintenance environment of setting and can be carried out Automatic continuous test.
The utility model can be accurately, automatically read continuously the length variations of expansive concrete, thereby draw concrete limited expansion rate, time saving and energy saving, work efficiency is high.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
The utility model is described in detail in detail with reference to the accompanying drawings.
With reference to Fig. 1, confined expansion bar of the present utility model 1 two ends are fixed on steel plate, and magnetic stand 1, magnetic stand 23 and magnetic switch are fixed on the steel plate of confined expansion bar two ends.Threaded rod 4 one end are threaded with magnetic stand 1, and the square contact jaw of one end contacts with displacement clock gauge 6, and displacement clock gauge gauge outfit withstands on the termination of threaded rod.Displacement clock gauge is threaded with magnetic stand 23, and fixing by the nut 5 that injects magnetic stand two.
Magnetic stand one lower end is magnetic apparatus, and upper end is the long rifled tube of 3cm, and magnetic-adsorption is controlled by magnetic switch.Magnetic stand two lower ends are magnetic apparatus, and upper end is round tube, and magnetic-adsorption is controlled by magnetic switch.
Threaded rod 4 thread end are 3cm screw thread, and square contact jaw is 1.5cm*1.5cm square bar baffle plate.
While using the utility model, confined expansion bar in utility model is put into concrete test die moulding together, form removal after concrete reaches strength of mould stripping, by the concrete confined expansion test block two ends steel plate scrub of form removal, then by magnetic stand 1, magnetic stand 23 is fixed on the steel plate at confined expansion bar two ends by confined expansion bar two ends magnetic switch, by threaded rod 4 thread end be screwed into Magnetic gauge stand with internal thread hole in, displacement clock gauge is inserted in Magnetic gauge stand two, and guarantee that displacement clock gauge gauge outfit withstands on the square contact jaw contact of threaded rod, displacement clock gauge gauge outfit withstands on the termination of threaded rod.Fixing by upper end nut 5, concrete sample is put under the maintenance environment of setting and can be carried out Automatic continuous test.
The utility model can be accurately, automatically read continuously the length variations of expansive concrete, thereby draw concrete limited expansion rate, time saving and energy saving, work efficiency is high.
