Detailed Description

The technical solution of the present invention will be described in further detail through the following embodiments.

As shown in fig. 1-3, a slump testing device for fresh concrete comprises a slump barrel 1 made of aluminum alloy or steel, a bottom support 2, a handle 3 and a vibrating rod 4;

the slump cone 1 is a cone barrel structure with the upper end caliber smaller than the lower end caliber, two sides of the upper part of the cone barrel structure are provided with upper handles 11, and the upper handles 11 are in a structure that the U-shaped reverse buckle is fixed on the cone barrel structure; pedals 12 are arranged on two sides of the bottom end of the cone barrel structure.

The collet 2 includes that the upper surface is planar octagon layer board 21, locates be used for pushing down on the layer board 21 the clamp plate 22 of footboard 12 with locate the couple 23 at the layer board 21 back, one side of layer board 21 still is provided with the via hole 24 that is used for passing the stick of vibrating 4, and under fold condition, via hole 24 is coaxial with 5 through-holes on the handle, the couple 23 at the layer board 21 back is rotatory couple, can hide after the rotation in the back space of layer board 21, avoids keeping flat of protruding influence layer board 21.

The lifting handle 3 is a U-shaped lifting handle, the two hanging parts of the lifting handle 3 are respectively hinged to the two horizontal sides of the bottom support 2, and a through hole 5 is formed in the center of the top end of the lifting handle 3.

The vibrating rod 4 is a rod body with scales 6 arranged on the surface, and the diameter of the vibrating rod 4 is smaller than that of the through hole 5 at the top end of the handle 3.

In this embodiment, the pressing plate 22 is a spinning structure, and includes a pressing plate body 221 and a hinge shaft 222, the pressing plate body 221 is hinged to the upper surface of the supporting plate 21 through the hinge shaft 222, the lower edge of the pressing plate body 221 is an inclined surface 223 from inside to outside, and the upper surface of the pedal 12 is an equi-inclined surface structure 121 adapted to the inclined surface 223 of the lower edge of the pressing plate body.

The working principle is as follows:

first step, place the collet on the testboard, detect whether the upper surface of layer board 21 is level, if not level, need more change position or fill up the stopper iron sheet, make the upper surface level, at this moment, handle 3 is folding to be kept flat in one side of collet.

Secondly, the slump bucket is placed on the upper surface of the supporting plate 21, the position of the pedals 12 is adjusted to be aligned with the pressing plate 22, and then the pressing plate 22 is rotated to tightly press and fix the pedals 12.

And thirdly, according to the requirement of technical specification, uniformly filling concrete into the barrel from the top of the slump barrel for three times, so that the filling amount of each layer can be conveniently controlled (the concrete is easily controlled according to scales on the transparent barrel body), leveling the top surface of the slump barrel by using a touch knife after the three-time filling and the inserting and tamping are finished, and placing the slump barrel on one side after the slump barrel is slightly lifted.

And fourthly, measuring the slump of the concrete by using the scales on the vibrating rod.

After the test is finished, the equipment is cleaned, the hook 23 is turned out, the upper handle 11 of the slump bucket 1 is hung on the hook 23, the vibrating rod sequentially penetrates through the through hole 5 and the through hole 24 to enter the slump bucket 1, and the equipment is transferred to a storage position by holding the handle 3.

In the third step, for conveniently reading the scale, the in-process of cubic injection concrete, the vibrating rod can not take out, directly buries in the concrete, nevertheless need keep vibrating rod's straightness that hangs down, and the through-hole position on the accessible handle is centering, like this after taking out the slump bucket, just can direct reading, and is very convenient.
