Abstract
The invention discloses an auxiliary porous compactor of a regenerated coarse aggregate concrete briquette, which comprises an impact base plate, an impact guide rod and an impact hammer, wherein the impact guide rod is fixedly arranged on the impact base plate; and the impact hammer is arranged in a step manner and movably arranged on the impact guide rod. The compactor disclosed by the invention can be used for discharging air in gaps among coarse and fine aggregates, can effectively overcome the problem of large coarse friction force on the surface of the regenerated coarse aggregate, and ensures that the briquette is more compact.
Description
Technical field
The present invention relates to a kind of closely knit device of auxiliary porous of regenerated coarse aggregate concrete test block, belong to the concrete strength field tests of civil engineering work subject.
Background technology
At present, along with the further propelling of energy-saving and emission-reduction, regeneration concrete has obtained increasing application at aspects such as construction work, road engineering, hydraulic engineerings.It is made 150mm*150mm*150mm reference block usually in the laboratory when measuring concrete intensity.Need in the test block manufacturing process it is carried out necessary vibrating to reach the packing of design.Because the regenerated coarse aggregate material compared primary with it in the regeneration concrete is coarse, intergranular friction force is big, the traditional Vibration Technology in laboratory can not effectively be vibrated to it, bubble in the test block can not be discharged fully, causes the leakiness of vibrating to influence the intensity test of test block easily.
Summary of the invention
The object of the present invention is to provide a kind of closely knit device of auxiliary porous of regenerated coarse aggregate concrete test block.Closely knit device of the present invention not only can fully be discharged the air in the coarse-fine aggregate slit, and can effectively overcome the big problem of regenerated coarse aggregate rough surface friction force, makes test block more closely knit.
In order to reach above-mentioned purpose, solution of the present invention is:
A kind of closely knit device of auxiliary porous of regenerated coarse aggregate concrete test block comprises and impacts base plate, impact guide rod and ram hammer; Wherein impacting guide rod is fixedly mounted on the impact base plate; The stepped setting of ram hammer, and ram hammer is movably arranged on the impact guide rod.
Offer mounting hole on the described impact base plate, impact guide rod and be fixedly mounted in the mounting hole that impacts base plate.
Described mounting hole is the circular hole of diameter 10mm, and described impact guide rod is a cylindrical steel rod, and long 400mm, diameter are 10mm.
Described mounting hole is a threaded hole, and it is threaded with the impact guide rod.
Described impact base plate is square steel plate, and the length of side is 170mm, and thickness is 10mm.
Offer 8 exhaust holes on the described impact base plate, and be uniform setting.
Described exhaust hole diameter is 10mm.
The upper bottom surface diameter of the ram hammer of described stepped setting is 40mm, and the bottom surface diameter is 60mm, and the centre offers the through hole that diameter is 10mm, ram hammer is linked in impacts on the guide rod.
Beneficial effect of the present invention is: the present invention has overcome traditional vibration compacting device can not be the defective of the abundant vibration compacting of regenerated coarse aggregate concrete test block, closely knit device of the present invention not only can fully be discharged the air in the coarse-fine aggregate slit, and can effectively overcome the big problem of regenerated coarse aggregate rough surface friction force, make test block more closely knit, and method is easy, and is simple in structure.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the structural representation that the present invention impacts base plate.
Embodiment
The closely knit device of auxiliary porous of a kind of regenerated coarse aggregate concrete test block of present embodiment, shown in Figure 2 as Fig. 1, comprise and impact base plate 1, impact guide rod 2 and ram hammer 3; Impacting base plate 1 is square steel plate, and the length of side is 170mm, and thickness is 10mm.Impact on the base plate 1 being evenly equipped with 8 exhaust holes 5, exhaust hole 5 diameters are 10mm.Impact on the base plate 1 also offering mounting hole 4, described mounting hole 4 is the circular hole of diameter 10mm, and described impact guide rod 2 is a cylindrical steel rod, and long 400mm, diameter are 10mm.Mounting hole 4 is a threaded hole, and mounting hole 4 is threaded with impacting guide rod 2, and impact guide rod 2 is fixedly mounted in the mounting hole 4 that impacts base plate 1.Ram hammer 3 is movably arranged on and impacts on the guide rod 2, makes ram hammer 3 impact free-falling on the guide rod 2.Ram hammer 3 stepped settings, the upper bottom surface diameter is 40mm, and the bottom surface diameter is 60mm, and the centre offers the through hole 6 that diameter is 10mm, ram hammer 3 is linked in impacts on the guide rod 2.After the regeneration concrete test block is tentatively vibrated traditionally, the auxiliary closely knit device of present embodiment is placed on to hold the interior length of side of tentatively vibrating be on the steel mold of 150mm*150mm, make its planar central overlapping substantially; Make it along impacting guide rod 2 free-fallings behind the pull-up ram hammer 3, ram hammer 3 final impact base plate 1 under action of gravity forms one-shot, impact energy makes the sample gas inside discharge along 8 exhaust holes 5, the friction force that overcomes simultaneously between the concrete coarse aggregate in the test block is arranged closely it, and bump can make for 8-10 time test block more closely knit.Owing to impact base plate 1 length of side 170mm greater than traditional test block mould length of side 150mm, the closely knit device of this auxiliary porous can not exert an influence to the size of test block in work.The present invention has overcome traditional vibration compacting device can not be the defective of the abundant vibration compacting of regenerated coarse aggregate concrete test block, closely knit device of the present invention not only can fully be discharged the air in the coarse-fine aggregate slit, and can effectively overcome the big problem of regenerated coarse aggregate rough surface friction force, make test block more closely knit, and method is easy, and is simple in structure.
