Abstract
The utility model provides a cement concrete slump measuring device which comprises a cylinder body, a bottom plate and a measuring device, wherein the cylinder body is connected with the bottom plate by using bolts; the measuring device comprises a vertical range pole, a steel ruler and a horizontal scale; the vertical range pole and the steel ruler are both vertically and fixedly arranged on the bottom plate; and the horizontal scale is sleeved on the vertical range pole to be used for reading the slump of cement concrete. The cement concrete slump measuring device has a simple structure and is convenient to operate; and the measuring device keeps being relatively fixed with a tested body, so that the measurement accuracy is high.
Description
Technical field
The utility model relates to a kind of building materials testing tool, particularly relates to a kind of cement concrete slump measurement mechanism.
Background technology
The slump is an important performance of cement concrete, directly has influence on the plasticizing capacity and the pumpability energy of cement concrete.Existing slump surveying instrument mainly is that the slump is measured tube, its principle of work be with the cement concrete mixture in accordance with regulations method pack in the standard circular cone slump cone, fill strickling after, vertically upward tube is mentioned, move on on one side.The cement concrete mixture is because deadweight will produce the slump phenomenon.Measure the height of downward slump then, this height dimension is exactly the slump.
But such slump is measured tube and had following problem: it is surface level, solid and do not absorb water that the plane that base plate is placed requires, such base plate lacks sign property or uniqueness, the working-yard under various construction environment and condition particularly, the plane that its base plate of the place that in situ test is selected is placed requires the property of there are differences, and is random big.Both spent operating manpowers are tested in shop experiment and working-yard, and the time, test result etc. are compared, and otherness can be bigger.
Slump cone is placed on the base plate center, and the pedal that people's pin is stepped on the slump cone both sides is slump cone fixedly, people charging and tamping cement concrete, and this operation work efficiency is slow and fixedly the slump cone labour intensity of standing for a long time is big; Insert at tamper and to smash in the process, produce certain friction resistance between slump barrel and the cement concrete mixture, slump cone makes progress or move left and right easily, cement concrete cone height increase thereupon or the deflection chassis center outside, cement concrete cone height tends to surpass the calibrated altitude of slump cone 300mm, influence the measurement of its standard cement concrete cone difference in height, can't embody test index really and accurately.
After having lifted from slump cone, in that to measure tube high during with the difference in height that collapses between the cement concrete cone peak of back, graduated scale levelness or graduated scale verticality are for range estimation (gesticulating) method, and be greatly random.The difference reading of scale and cement concrete cone height is not directly perceived, and reading error is also bigger, and slump measuring accuracy is difficult to be accurate in the 1mm of requirement.
The operating space is little, and environment is poor.Adopt fixedly slump cone of pedal that people's pin steps on both sides, personnel operation activity space relative fixed simultaneously, is inserted when smashing the cement concrete mixture in charging with tamper, people's clothing is polluted big, and operation is inconvenience extremely.
The utility model content
The utility model is measured tube to the existing cement concrete slump and is improved, and aims to provide a kind of simple in structure, easy to operate and cement concrete slump measurement mechanism that accuracy is high.
The utility model is by the following technical solutions: a kind of cement concrete slump measurement mechanism, comprise cylindrical shell, base plate and measurement mechanism, and described cylindrical shell is connected by bolt with base plate; Described measurement mechanism comprises vertical mark post, horizontal ruler and steel ruler; Described vertical mark post is parallel with the cylindrical shell central axis with steel ruler and on same plane, is vertically set on the described base plate, and described horizontal ruler is enclosed within on the described vertical mark post.
In the utility model, described cylindrical shell bottom is welded with contiguous block, and contiguous block is provided with bolt hole, and described bolt is fixedly installed on the base plate by welding.
In the utility model, on described cylindrical shell, be provided with two handles.
In the utility model, described vertical mark post and steel ruler welding are arranged on the described base plate, and described horizontal ruler can rotate on described vertical mark post.
Base plate in the utility model is the steel surface plate of standard, is connected by bolt between cylindrical shell and the base plate, and cylindrical shell is sheet steel or other metal truncated cone-shaped tube approved products, its inner wall smooth.2/3rds highly locate two handgrips of peace outside slump cone, are convenient to behind the tamping cement concrete cylindrical shell be mentioned.The cylindrical shell lower end is symmetrically welded with at least 2 contiguous blocks with tubular axis, is provided with bolt hole, is convenient to by the bolt cylindrical shell.Vertical mark post and steel ruler all are to be weldingly fixed on the base plate, keep vertical with base plate, graduated scale levelness and graduated scale verticality are fixed, when measuring that tube is high to try difference in height between the body peak with the back cement concrete that collapses, the difference reading of scale and cement concrete cone height is directly perceived, can reduce the randomness of range estimation, slump measuring accuracy can reach in the 1mm.
In sum, the utility model is a kind of simple in structure, easy to operate and cement concrete slump measurement mechanism that accuracy is high.
Description of drawings
Fig. 1 is a front view of the present utility model.
Fig. 2 is a left view of the present utility model.
Fig. 3 is a vertical view of the present utility model.
Number in the figure: 1-cylindrical shell, 2-handle, 3-steel ruler, 4-base plate, 5-bolt, 6-contiguous block, the vertical mark post of 7-, 8-horizontal ruler, the 9-collar, 10-nut.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Referring to Fig. 1, cylindrical shell 1 bottom is welded with contiguous block 6, is provided with bolt hole on contiguous block 6, and bolt 5 passes bolt hole and cooperates with nut 10 cylindrical shell 1 is fixedlyed connected with base plate 4, and bolt 5 is weldingly fixed on the base plate 4, is provided with two handles 2 on cylindrical shell 1.Referring to Fig. 2 and Fig. 3, vertical mark post 7 is parallel with cylindrical shell 1 central axis with steel ruler 3 and on same plane, is arranged on the base plate 4 by welding, and horizontal ruler 8 is provided with the collar 9, the collar 9 can rotate on vertical mark post 7, and maintenance is with vertical on horizontal ruler 8 and the vertical mark post 7.
The slump process that detects cement concrete is as follows: earlier cylindrical shell 1 is fixedlyed connected by bolt 5 with base plate 4, then cement concrete to be measured is packed in the cylindrical shell and tamping, after cement concrete is filled strickling, contact with the cylindrical shell peak by horizontal ruler 8 one ends, obtain the height of cylindrical shell 1; By handle 2 cylindrical shell 1 is mentioned, cement concrete to be measured is because deadweight will produce the slump phenomenon, range estimation cement concrete examination body no longer collapses, can horizontal ruler 8 will be moved up and down, the peak of one end with the back cement concrete examination body that collapses contacted, and the other end points to steel ruler 3, directly reading, the height of cement concrete examination body after promptly obtaining collapsing, the difference in height that the cylindrical shell and the back cement concrete that collapses try body is the slump of cement concrete.Because cement concrete moisture easily runs off, whole testing process requires to finish in 5 minutes.
