Concrete slump measurement mechanism
Technical field
The utility model relates to a measurement mechanism, especially a kind of be mainly used in solving in concrete slump measuring process the manual operation of conventional concrete slump measuring device measure inaccurate, easily to make dirty the concrete slump measurement mechanism of problem of footwear and pin.
Background technology
Concrete slump refers to concrete workability, and namely whether concrete is easy to constructing operation and performance uniformly densely, is a very comprehensive performance.Comprising mobility, cohesiveness and water-retaining property.Affect workability to mainly contain water consumption, water cement ratio, sand coarse aggregate ratio and comprise cement type, aggregate condition, time and the aspect such as temperature, additive.What ensure construction specifically normally carries out key factor.
The measuring method of the tradition slump: such as use the trumpet-shaped slump bucket of a 100mm suitable for reading, end opening 200mm, high 300mm, penetration concrete divides three fillings, the rear beater of each filling hits 25 times, after tamping along the even ecto-entad of bucket wall, floating.Then pull up bucket, concrete is because of deadweight generation slump phenomenon, and deduct the height of the rear concrete peak that collapses with the high 300mm of bucket, be called the slump, if difference is 10mm, then the slump is 10.
The measuring method of the above-mentioned slump is artificial measuring method, and one in measuring process, easily makes the shoes of gauger and pin be made dirty by concrete, is not easy to clean afterwards; Two pull up in the process of bucket, due to artificial factor, be difficult to accomplish that slump bucket pulls up perpendicular to surface level, after namely generation slump bucket front, rear, left and right are waved, favour surface level to pull up, the measuring accuracy of the slump will inevitably be had influence on so to a certain extent.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of improve accuracy of detection and decrease mixed earth to make dirty the concrete slump measurement mechanism of the situation such as pin, footwear.
The utility model solves technical scheme that its technical matters adopts: concrete slump measurement mechanism, comprise horizontal panel, support bar and slump bucket, described support bar hollow and be vertically fixed on surface level edge, vertically offer the slotted eye be communicated with inside at this support bar on the surface, this slotted eye is provided with scale mark; Support bar inside is provided with elevating lever, this elevating lever is provided through slotted eye and the armed lever be fixedly connected with slump bucket; Slump bottom of the barrel lateral surface being provided with wing plate, being combined with the fastener device for compressing wing plate at horizontal panel.
Described fastener device comprises spring and is connected to the buckle at spring two ends, the edge snap-fit engagement of buckle and horizontal panel.
Elevating lever is movably installed with the sleeve be positioned at below armed lever, and this sleeve is fixedly connected with the high bar of the survey parallel with horizontal panel.
Described slump bucket outside surface is provided with the handle being convenient to extract slump bucket.
The beneficial effects of the utility model are: concrete slump measurement mechanism of the present utility model is by the cooperation of surface plate, support bar, slump bucket and fastener device etc., the precision not only making to measure the mixed earth slump improves, and decreases mixed earth and to make dirty the situation such as pin, footwear.When taking off slump bucket, moving upward with elevating lever, avoiding swing, improve measuring accuracy; Simultaneously fastener device compresses wing plate in use, manually need not slam compression by pin, decreases workmen and to make dirty the situation such as pin, footwear.Comprise spring due to described fastener device and be connected to the buckle at spring two ends, the edge snap-fit engagement of buckle and horizontal panel, can compress easily and take off, improve work efficiency.Owing to being movably installed with the sleeve be positioned at below armed lever on elevating lever, this sleeve is fixedly connected with the high bar of the survey parallel with horizontal panel, when needing to measure coagulation degree height, coordinates the scale mark at slotted eye place easily and accurately to measure.Because described slump bucket outside surface is provided with the handle being convenient to extract slump bucket, when needing human assistance to get slump bucket under special circumstances, quite laborsaving convenience.

Embodiment
Below in conjunction with accompanying drawing, the utility model will be further described, but protection domain of the present utility model is not limited to the following stated.
As shown in Figure 1 and Figure 2, concrete slump measurement mechanism of the present utility model, comprise horizontal panel 1, support bar 2 and slump bucket 6, described support bar 2 hollow and be vertically fixed on surface level 1 edge, vertically offer the slotted eye 3 be communicated with inside at this support bar 2 on the surface, this slotted eye 3 is provided with scale mark; Support bar 2 inside is provided with elevating lever 4, this elevating lever 4 is provided through slotted eye 3 and the armed lever 5 be fixedly connected with slump bucket 6; Slump bucket 6 bottom outside face being provided with wing plate 7, being combined with the fastener device for compressing wing plate 7 at horizontal panel 1.Concrete slump measurement mechanism of the present utility model, by the cooperation of surface plate 1, support bar 2, slump bucket 6 and fastener device etc., not only makes the precision measuring the mixed earth slump improve, and decreases mixed earth and to make dirty the situation such as pin, footwear.When taking off slump bucket 6, moving upward with elevating lever, avoiding swing, improve measuring accuracy; Simultaneously fastener device compresses wing plate 7 in use, manually need not slam compression by pin, decreases workmen and to make dirty the situation such as pin, footwear.
As preferably, described fastener device comprises spring 11 and is connected to the buckle 12 at spring 11 two ends, and buckle 12 and the edge snap-fit engagement of horizontal panel 1, can compress easily and take off, improve work efficiency.It should be noted that one of them buckle 12 can be fixed on horizontal panel 1 always in actual mechanical process, the buckle of only operation, drops to prevent bayonet unit.
As preferably, elevating lever 4 is movably installed with the sleeve 9 be positioned at below armed lever 5, this sleeve 9 is fixedly connected with the high bar 10 of the survey parallel with horizontal panel 1, when needing to measure coagulation degree height, the scale mark at slotted eye place is coordinated easily and accurately to measure, when not needing to measure, the high bar 10 of survey can be rotated to out of the way position.
As preferably, described slump bucket 6 outside surface is provided with the handle 8 being convenient to extract slump bucket 6, when needing human assistance to get slump bucket 6 under special circumstances, and quite laborsaving convenience.
More than show and describe ultimate principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and instructions just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
