[detailed description of the invention]
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain this utility model, be not used to limit this utility model.
Embodiment 1
As it is shown in figure 1, the special ruler of the measurement slump of this utility model offer, including base 1, support member 2 and ruler 3.
Support member 2 includes the first support 21 and the second support 22, the bottom of the first support 21 is fixing with base 1 to be connected, one end of second support 22 is fixedly attached on the first support 21, and the vertical height of the bottom surface of the second support 22 and base 1 is highly consistent with the slump bucket for testing slump；Ruler 3 can be vertically arranged on the second support 22 up or down.
Preferably, special ruler also includes quill 4 and the bolt (not shown) being mechanically connected with quill 4.Ruler 3 is flexibly connected with the second support 22 by quill 4, and ruler 3 is positioned by bolt, and this position fixing process is essentially consisted in when ruler 3 moves up and down in quill 4 and positioned by bolt.The location moving up and down cooperation bolt of ruler 3, it is achieved the accurate measurement to slump.
Preferably, the second support 22 is provided with movable guiding rail 5, and movable guiding rail 5 extends to the two ends of the second support 22, and quill 4 drives ruler 3 to move along movable guiding rail 5.Ruler 3 can on horizontally disposed second support 22 transverse shifting, ruler 3 can vertically move by the vertical direction again, the combination of horizontal and vertical motion, facilitates the special ruler measurement to slump.
Preferably, the second support 22 includes left branch 221 and right branch 222.One end of right branch 222 is fixing with the first support 21 to be connected, and the other end of right branch 222 is connected by rotating shaft (not shown) with left branch 221, and left branch 221 is rotated centered by rotating shaft by rotating shaft.The special ruler of the measurement slump that the present embodiment provides designs for folding, ruler 3 can be moved adjacent to one end of the first support 21 when not in use by quill 4, left branch 221 carries out 90 degree of rotations by rotating shaft to base 1 direction so that left branch 221 is parallel to the first support 21.Special ruler after folding, space occupancy rate is low, is transporting and is depositing in process not easily damaged, it is ensured that the measuring accuracy of this special ruler and service life thereof.
Further, base 1 is metab 1, for instance the ferrum adopting proportion bigger makes base 1.Support member 2 is wooden support member.Ruler 3 is wooden ruler.Base 1 that quality is bigger and the less support member 2 of quality and ruler 3, facilitate special ruler location in use, will not produce because of support member 2 and ruler 3 mass are excessive, cause measuring inaccurate, and wooden support member and wooden ruler cost of manufacture relatively low.
Preferably, the first support 21 and/or the second support 22 are bar shape.
Usually, in slump measurement process, the height of the slump bucket of use is 300mm, and therefore the second support 22 could be arranged to 300mm with the vertical height of the bottom surface of base 1.It should be appreciated by those skilled in the art that the setting with the vertical height of the bottom surface of base 1 of second support 22 is only in order to explain this utility model, not in order to limit this utility model, this vertical height can be changed along with the change of the height of slump bucket.Further, the measurement scope of ruler 3 can be 0-300mm.
When the special ruler using the measurement slump of this utility model offer carries out the measurement of slump, step is as follows:
1, before test, slump cylinder is inside and outside cleans, and is placed on the flat board that water moistened (should pad with Polypropylence Sheet during flat board water suction), steps on tight footboard.
2, concrete representative sample divides three layers load in cylinder, and every layer of loading is slightly greater height than 1/3 that cylinder is high, uniformly plugs and pounds repeatedly on the cross section of each layer with tamper, for instance 25 times.Plug and pound and carry out in concrete entire area, along helix by edge to center, when plugging and pounding bottom, be inserted to bottom, when plugging and pounding other two-layer, this layer should be inserted and insert lower floor about 20～30mm, plugging and pounding and vertically downward (except marginal portion), must not must impact.When plugging and pounding top layer, the concrete of loading should exceed slump nozzle, adds mixture at any time with plugging and pounding in process.After top layer plugs and pounds, action tamper sawed and rolls, remove unnecessary concrete, polish nozzle with steamed bun cutter, shave the mix around at the bottom of cylinder.Then vertically mention slump cylinder immediately, carry cylinder and complete in 5～10s, and make concrete not by transverse direction and twisting force.Should complete in 150s from starting to be charged to the proposition slump cylinder process of haveing suffered.
3, slump cylinder is placed on one side of cone concrete sample, then special ruler the present embodiment provided is placed on flat board and near cone concrete sample, the wooden ruler that slides make bottom ruler with sample tip contact, the numerical value that now crossbeam bottom surface and ruler intersect on corresponding ruler is concrete slump, is accurate to 1mm.
The special ruler of the measurement slump that the present embodiment provides is when carrying out the measurement of slump, simple to operate, and accuracy of measurement is high, can guarantee that slump can be measured timely and accurately；Folding design facilitates the transport of special ruler and deposits.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equivalent replacement and improvement etc. made within spirit of the present utility model and principle, should be included within protection domain of the present utility model.
