Description
Technical field
The utility model relates to civil engineering material experimental provision field, specifically a kind of concrete slump detection dress
It sets.
Background technique
Civil engineering material refers to that for a variety of materials in civil engineering, concrete is a kind of important civil engineering material
Material, concrete slump are primarily referred to as the plasticizing capacity and pumpable performance of concrete, and the factor for influencing concrete slump is main
There are gradation differentials, water content, the weighing deviation of weighing apparatus, the dosage of additive, is easy the temperature etc. of ignored also cement.
Existing experimental provision is mostly made of circular platform type slump cone, funnel, tamper and graduated scale.Slump cone bottom
Two sides are equipped with firm banking and need operator to slam firm banking with both feet when in use, and another people fills concrete sample
Enter in cylinder and consolidate, then lift slump cone, measuring cylinder is high and difference in height after collapsing between concrete sample highest point, i.e.,
For the slump value of the concrete sample.
Existing apparatus is too simple, there is, needs more manual operation, slump cone more demanding to experimental situation ground
Bottom and ground face contact loosely, the disadvantages of elevation carrection is inaccurate.
Utility model content
To overcome the shortcomings of existing experimental provision and inherent shortcoming, the utility model proposes a kind of integral type Control Measures for Concrete Slump
Spend detection device.
In order to solve the above technical problems, the utility model is achieved using following technical scheme:
1, a kind of integral type concrete slump detection device, it is characterised in that: including bottom plate, be vertically installed on bottom plate
Fixed link slidably connects telescopic rod in fixed link, connects laser range finder on telescopic rod, and the probe of laser range finder is the bottom of towards
Plate, the other end of telescopic rod are fixed with circular platform type slump cone.
Bottom plate is chosen as rectangle iron plate, is separated by concrete with ground, avoids ground dry and wet degree and dust impurity pair
The influence of concrete workability, and guarantee the stability of device.
Preferably, telescopic rod is fixed in fixed link by sliding sleeve, and height of the sliding sleeve on telescopic rod is adjustable.
Preferably, telescopic rod and circular platform type slump cone are welded to connect.
Telescopic rod left end is connected with sliding sleeve, and laser range finder is arranged in the middle part of optional telescopic rod, and right end and circular platform type collapse
Cylinder welding is spent, telescopic rod can drive slump cone to move left and right, while can also be allowed to move up and down with sliding sleeve.
Preferably, circular platform type slump cone two sides are fixed with fixed pedestal.Before experiment starts, rotary table is tied down with fixing bolt
The fixed pedestal of type slump cone two sides, is fixed on slump cone on bottom plate.
It preferably, further include funnel, funnel detachable connection is at the top of circular platform type slump cone.Facilitate to circular platform type
Concrete sample is added in slump cone and is consolidated with tamper until filling it up with slump cone.
Laser range finder is ranging phase method instrument, to the distance between measuring instrument position and lower section object:
What is measured after slump cone raises up for the first time is distance of the instrument according to bottom plate, when laser range finder is moved to concrete sample
What is measured when top is instrument according to the distance at the top of concrete sample.
The utility model has the beneficial effects that
The advantages of slump that is convenient, accurately detecting cement concrete that the utility model has, reduction manual operation.
Detailed description of the invention
Fig. 1 is the utility model general front view.
Fig. 2 is the utility model slump cone lifting operation schematic diagram.
Fig. 3 is the utility model laser range finder operation schematic diagram.
Specific embodiment
Shown in Fig. 1, the utility model includes fixed link 1, telescopic rod 2, sliding sleeve 3, laser range finder 4, bottom plate 5, funnel
6, circular platform type slump cone 7, fixing bolt 8 and fixed pedestal 9.Fixed link 1 is fixed on bottom plate 5, and telescopic rod 2 passes through sliding sleeve
3 are connected with fixed link 1, and sliding sleeve 3 can move up and down in fixed link 1.Laser range finder 4 is set to 2 middle part lower section of telescopic rod.
Circular platform type slump cone 7 is welded on 2 right end of telescopic rod, becomes an overall structure.Before experiment starts, sliding sleeve 3 is adjusted, makes to justify
Bench-type slump cone 7 is contacted with bottom plate 5, and the fixed pedestal 9 of circular platform type slump cone two sides is tied down with fixing bolt 8, makes to collapse
Degree cylinder is fixed on bottom plate.Funnel 6 is added at the top of slump cone, and concrete sample is added and is consolidated with tamper and collapses until filling it up with
Degree of falling cylinder.
The utility model slump cone shown in Fig. 2 is lifted operation schematic diagram, withdraws funnel, releases bottom fixing bolt 8 about
Beam adjusts sliding sleeve 3 and is lifted slump cone, concrete is made to generate slump phenomenon because of self weight.Fixed sliding sleeve 3, protects telescopic rod 2
Hold fixed height, reuse laser range finder 4 measure at this time instrument according to the distance of bottom plate.
The operation schematic diagram of the utility model laser range finder shown in Fig. 3, adjusts telescopic rod 2, and mobile laser range finder 4 arrives mixed
Right above solidifying soil test specimen, instrument is measured according to the distance at the top of concrete sample.
Instrument finally is subtracted according to the distance at the top of concrete sample according to the distance of bottom plate with instrument again, and the coagulation can be obtained
The slump value of native test specimen.
