Abstract
The utility model discloses a lifting-type slump test bucket, which comprises a test bucket body which is of the shape of a circular truncated cone on the whole. The internal part of the test bucket body is a cavity structure. The upper end surface and the lower end surface of the test bucket body are open. Two lifting handles are arranged on the external side wall of the test bucket body. An operator uses two hands to press the lifting handles, the lower end surface of the test bucket body is kept to be in close contact with the ground surface or a steel plate to prevent grout from leaking and the problem that the test bucket body moves upwards when a tamping stick tamps the grout is solved; the two hands slowly lift up the lifting handles after the filling of the grout is completed, the force is easy to control, the lifting speed is controlled and the operation standardization is facilitated; by adopting the design of symmetrical lifting handles, the two hands of the operator can conveniently press or lift up the lifting handles and the design is compliant with the force applying habit and the operating method of the operator; and the cement grout can be dropped onto concrete as much as possible through the smooth side wall and the test results are guaranteed to be objective and accurate.
Description
Technical field
The utility model relates to the testing tool of a kind of slump in the concrete quality testing process, specifically is meant a kind of pull-type slump test bucket.
Background technology
Concrete is meant by the Binder Materials glued general designation that becomes whole engineered composite material of will gathering materials.Usually concrete one speech of saying is meant with cement makes Binder Materials, and sand, masonry gather materials; Cooperate by a certain percentage with water, through stirring, moulding, maintenance and cement concrete, also can add or not add additive and admixture, also claim normal concrete, it is widely used in civil engineering work.Parameters such as slump, diffusibleness, workability are concrete Specifeca tion speeifications; Slump mainly be meant concrete plasticizing capacity and pumpability can, influence the weighing deviation that slump mainly contains grating variation, water cut, horizontal device, the consumption of additive, the unheeded easily several aspects of temperature of cement in addition; Slump is meant concrete workability; Be exactly to guarantee normally carrying out of construction specifically, comprising concrete water-retaining property, flowability and cohesiveness.Workability is meant whether concrete is easy to constructing operation and performance uniformly densely, is that a very comprehensive performance wherein comprises flowability, cohesiveness and water-retaining property.Influencing workability mainly contains water consumption, water cement ratio, sand coarse aggregate ratio and comprises cement type, aggregate condition, time and several aspects such as temperature, additive.Same cement dosage match ratio is satisfying under the prerequisite of incorporation degree, and the more little concrete strength of slump increases more, and difficulty of construction also can increase, otherwise slump is big more, and concrete strength is low more, and difficulty of construction reduces.Concrete slump should should be taken all factors into consideration when selecting match ratio, and should adopt less slump according to the conditional decisions such as structure section, reinforcing bar content, transportation range, pouring procedure, means of transportation, the ability of vibrating and weather of buildings.Controlling concrete slump is the most basic requirement, also is the important means of ensuring the quality of products.At present the method for testing of slump is: with a trumpet-shaped slump test bucket, tamping behind the penetration concrete pulls up bucket then, and concrete produces the slump phenomenon because of deadweight, and with barrel high height that deducts concrete peak after the slump, its drop is slump.But there is defective in present test bucket, is seated in the closely knit process at tamping rod; Because concrete deadweight causes slump test bucket to move upward easily, slurries spill from the bottom, influence test result; Firmly inhomogeneous when promoting the test bucket simultaneously, pulling speed is difficult to control.
The utility model content
The purpose of the utility model is to overcome present slump test bucket when filling is concrete; The test bucket moves upward voluntarily owing to concrete deadweight and causes space, bottom spillage; Firmly inhomogeneous when promoting the test bucket simultaneously; The unmanageable problem of pulling speed provides a kind of pull-type slump test bucket.
The purpose of the utility model realizes through following technical proposals:
A kind of pull-type slump test bucket comprises that integral body is round table-like test bucket body, and test bucket body interior is a cavity structure, the equal opening in upper surface and lower surface, and the exterior side wall of said test bucket body is provided with two handles.Slump test bucket body integral body is truncated cone-shaped, and it has upper surface and the lower surface that is parallel to each other, and the upper surface is circular charging door, and the lower surface is circular discharging opening; During use, test bucket body is placed on the smooth earth or smooth steel plate of level, steel plate all need be used water-soaked with test bucket body and other apparatus, but can not there be the water that obviously flows on the surface; Concrete divided from the charging aperture of upper surface put into for three times, be about 1/3rd of total amount at every turn, all smash in the direction of the clock 25 times at every turn with tamping rod; At last that the upper surface is unnecessary concrete is removed, is polished, and will test the bucket body then and slowly promote, after promoting fully; Grout on the test bucket body is dropped onto on the concrete, and no longer mobile up to concrete, the height with test bucket body is a benchmark then; Measure concrete peak to the minor increment between the test bucket body upper surface, this distance is slump, is seated in the concrete process at tamping rod; The operator keeps test bucket body lower surface closely to contact with ground or steel plate with the hands by being pressed on the handle, prevents spillage; Overcome tamping rod and in smashing the process of holding, tested the problem that the bucket body moves upward, after filling finished, both hands were slowly mentioned handle; Control is firmly controlled the speed that promotes easily, is convenient to working specification.
Said two handles are symmetrically distributed about the axis of test bucket body.Say that further adopt the handle design of symmetric form, the both hands of being convenient to operating personnel are pushed or upwards promoted, match operation personnel's firmly custom and mode of operation.
Described test bucket body is made up of steel plate, and the sidewall of its internal cavities is smooth curved surface.Further say; Adopt smooth steel plate to process a test bucket body, its inner wall smooth help concrete smash to hold be seated, improve its packing; Minimizing air etc. are to the influence of test result; And smooth sidewall can drop onto grout as much as possible on the concrete, guarantees objective, the accuracy of test result.
The utility model compared with prior art has following advantage and beneficial effect:
A kind of pull-type slump test of 1 the utility model bucket is seated in the concrete process at tamping rod, and the operator is with the hands by being pressed on the handle; Keep test bucket body lower surface closely to contact, prevent spillage, overcome tamping rod and in smashing the process of holding, tested the problem that the bucket body moves upward with ground or steel plate; After filling finished, both hands were slowly mentioned handle, and control firmly easily; The speed that control promotes is convenient to working specification;
A kind of pull-type slump test of 2 the utility model bucket adopts the handle design of symmetric form, and the both hands of being convenient to operating personnel are pushed or upwards promoted, match operation personnel's firmly custom and mode of operation;
A kind of pull-type slump test of 3 the utility model bucket; Adopt smooth steel plate to process a test bucket body, its inner wall smooth help concrete smash to hold be seated, improve its packing; Minimizing air etc. are to the influence of test result; And smooth sidewall can drop onto grout as much as possible on the concrete, guarantees objective, the accuracy of test result.
