Description

Equipment is kept somewhere in a kind of dry concrete test block

Technical field

The utility model relates to a kind of concrete strength testing apparatus of field of civil engineering, is specifically related to a kind of dry concrete test block and keeps somewhere equipment.

Background technology

Dry concrete is the concrete (sometimes the slump be 0mm) of the slump less than 10mm.Because the concrete slump is little, leaves and takes method according to the test block of plastic concrete (slump is greater than 30mm) and can't carry out.It is several that the placement method of existing dry concrete test block mainly contains compacting process, pressurization and vibratory drilling method:

(1) compacting process.After compacting process mixes and stirs the dry concrete material exactly, toward the standard die trial (during the filler of 150mm * 150mm * 150mm) with drill steel insert real (in case of necessity with hand beat, drill steel hits reality) method make the concrete test block forced shaping.The test block that this method is kept somewhere, though inner very closely knit, the intensity of the dry concrete that records is well below actual strength.

(2) pressurization.Pressurization is exactly when test block forming, adopts stressed method to make the concrete test block forced shaping.The test block that this method is kept somewhere, internal voids is many, the test block leakiness, the intensity of the dry concrete that records is well below actual strength.

(3) vibratory drilling method.Vibratory drilling method is exactly when test block forming, adopts the method for vibrations to make the concrete test block forced shaping.The test block that this method is kept somewhere, internal voids is many, the test block leakiness, the intensity of the dry concrete that records is well below actual strength.And test block when keeping somewhere grout spray contaminated environment easily.

Above method all can not be reacted the strength character of dry concrete truly, and the concrete just main performance index of intensity.This makes promoting the use of of dry concrete be restricted.

Summary of the invention

In order to overcome above-mentioned the deficiencies in the prior art part, the utility model provides a kind of dry concrete test block to keep somewhere equipment, and existing V-B consistometer is transformed, and the indwelling problem of dry concrete test block is well solved.

The utility model is achieved by the following technical solution: equipment is kept somewhere in a kind of dry concrete test block, comprise V-B consistometer, base is arranged on the V-B consistometer, motor and bumper are housed on the base, but the scale bar of up-down adjustment is arranged at V-B consistometer top, the lower end of scale bar is fixed with transparent gland, on the transparent gland counterweight is housed, be fixed with the die trial pallet above the described bumper, die trial pallet internal fixation has the standard die trial, the standard die trial be positioned at transparent gland under, the lower surface of described transparent gland is fixed with cushion pad, the shape of described cushion pad is the circle that adapts with transparent gland, and the centre of cushion pad has and the identical square hole of standard die trial inner chamber cross sectional dimensions.

Described die trial pallet is the box body of upper end open, box body two ends jug; Both sides are fixed with clamp above the described die trial tray substrate, on the clamp on arbitrary limit or both sides screw hole I are arranged, and are fixed with baffle plate above the die trial tray substrate, and the clamp on baffle plate and both sides surrounds and forms and the suitable space of standard die trial shape; On the base plate of described die trial pallet mounting hole is arranged, on the header board of die trial pallet screw hole II is arranged.

The lining plank that can split is arranged in the square hole of described cushion pad, and lining plank is the square plate suitable with square hole.

The beneficial effects of the utility model are: adopt structure of the present utility model, concentrated the method for pressurization and vibration, and can keep somewhere concrete test block with the concrete standard die trial, make the fine moulding of dry concrete, the intensity that can truly reflect dry concrete has been utilized existing V-B consistometer equipment simultaneously, and is simple and practical, with low cost, be convenient to engineering and use.

Embodiment

Equipment is kept somewhere in a kind of as shown in drawings dry concrete test block, comprise V-B consistometer 1, base 11 is arranged on the V-B consistometer 1, motor 12 and bumper 13 are housed on the base 11, but the scale bar 14 of up-down adjustment is arranged at V-B consistometer 1 top, the lower end of scale bar 14 is fixed with transparent gland 15, on the transparent gland 15 counterweight 5 is housed, by bolt die trial pallet 2 is arranged above the described bumper 13, die trial pallet 2 internal fixation have standard die trial 3, the standard die trial 3 preferred 150mm * 150mm * 150mm specifications that adopt, 28 days the intensity of concrete that this specification standards test block records is concrete strength, the intensity that other test block draws must just be not easy to the engineering practical application through converting.

Standard die trial 3 be positioned at transparent gland 15 under, the lower surface of described transparent gland 15 is fixed with cushion pad 6, the shape of described cushion pad 6 is the circles that adapt with transparent gland 15, and the centre of cushion pad 6 has and the identical square hole of standard die trial 3 inner chamber cross sectional dimensions.Because the space was bigger when the dry concrete material was gone into mould, closely knit must have a process.When concrete material was just gone into mould, it was suitable for reading generally all to exceed mould, can make top transparent gland 15 be in non-equilibrium state like this, and grout is overflowed.In addition, keep somewhere in the test block operating process, because the vibration of bumper 13, gland 15 certainly will produce with standard die trial 3 and collide, and sends noise.So, cushion pad 6 is made by the thick rubber blanket of 10mm, the outside is circular, diameter is 220mm, there are 150 * 150 square holes the centre, stick with glue and be connected on formation on the gland 15, its effect one is gland and die trial collision when avoiding duty, the 2nd, avoid the grout ejection in the dry concrete test block indwelling process.

As shown in Figure 1 and Figure 2, the lining plank 4 that can split is arranged in the square hole of cushion pad 6, lining plank 4 is square plates suitable with square hole.Lining plank is that the length of side is that 150mm, thickness are the square plate of 10mm, can use the steel plate processing and fabricating, also can be with not making with other materials processing of concrete generation chemical action.Its effect is after concrete material is compacted sinking, fills up the gap between transparent gland 15 and the concrete material.

As Fig. 4, Fig. 5, die trial pallet 2 shown in Figure 6 are box bodys of upper end open, box body two ends jug 24; Both sides are fixed with four clamps 21 above described die trial pallet 2 base plates, wherein on Yi Bian two clamps 21 screw hole I 21.1 is arranged, be fixed with baffle plate 25 above die trial pallet 2 base plates, baffle plate 25 surrounds formation and the suitable space of standard die trial 3 shapes with the clamp 21 on both sides; Two mounting holes 23 are arranged on the base plate of described die trial pallet 2, screw hole II 22 is arranged on the header board of die trial pallet 2.Die trial pallet 2 is formed by Q235 steel plate processing and fabricating, is used for fixing concrete standard die trial 3, and energy and bumper 13 are connected into an integral body when making standard die trial 3 duties, during off working state, and can be for convenience detach.

During use, pass through mounting hole 23 with screw or bolt, die trial pallet 2 is installed and is fastened on the bumper 13, to fill the standard die trial 3 of concrete material then and put into die trial pallet 2, the clamp 21 that is installed in baffle plate 25 and both sides surrounds in the space of formation, and screw in respectively in two screw hole I 21.1 and the screw hole II 22 with screw, standard die trial 3 is fastened in the pallet.Adjust scale bar 14 afterwards, transparent gland 15 is placed on standard die trial 3 tops, it is suitable for reading that cushion pad 6 is adjacent to die trial, just can carry out the indwelling operation of dry concrete reference block then.
