Detailed Description

In order to better understand the technical content of the present invention, specific embodiments are described below with reference to the accompanying drawings.

In this disclosure, aspects of the present invention are described with reference to the accompanying drawings, in which a number of illustrative embodiments are shown. Embodiments of the present disclosure are not necessarily intended to include all aspects of the utility model. It should be appreciated that the various concepts and embodiments described above, as well as those described in greater detail below, may be implemented in any of numerous ways, as the disclosed concepts and embodiments are not limited to any one implementation. In addition, some aspects of the present disclosure may be used alone, or in any suitable combination with other aspects of the present disclosure.

The utility model aims to provide a concrete slump testing cylinder which is mainly applied to slump testing of concrete and aims to solve the problem that the concrete cone slump is influenced by horizontal movement in the process of pulling out the testing cylinder upwards after the concrete is filled, so that the influence on the concrete cone slump is reduced when the testing cylinder is separated from the concrete cone after the concrete is filled.

So, after concrete filling finishes, as long as separate two semi-cylinder bodies in the horizontal direction, alright get rid of the test section of thick bamboo, owing to get rid of the period in the twinkling of an eye alright break away from with the concrete awl, can avoid breaking away from the influence that the in-process touched the concrete awl and caused, consequently can guarantee the accuracy of concrete awl slump result, greatly improve the success rate that slump detected.

Further, in a preferred embodiment, to improve the accuracy of the filling amount of the concrete in the three-time filling process, each half cylinder comprises an inner cylinder 1 and an outer cylinder 2.

Wherein, interior barrel 1 adopts the barrel that the transparent plastic material was made, and interior barrel 1 is set up to the half circular truncated cone barrel, and its lateral wall upper portion and lower part have all seted up the ladder groove, and outer barrel 2 adopts the metal barrel of stainless steel, and outer barrel 2 is set up to the half circular truncated cone barrel to can laminate in 1 outer wall block of barrel and fix on the ladder groove.

Therefore, the middle part of the slump test cylinder is transparent, the filling amount can be conveniently determined when concrete is filled, whether the mixed concrete cone has a cavity or not can be seen, and the manufacturing of the concrete cone is facilitated.

Specifically, the outer cylinder 2 comprises an upper cylinder cover 21 and a lower cylinder cover 22, the upper cylinder cover 21 is fixedly installed on the upper portion of the inner cylinder 1, the lower cylinder cover 22 is fixedly installed on the lower portion of the inner cylinder 1, and the volume of the cavity inside the upper cylinder cover 21 is equal to the volume of the cavity inside the lower cylinder cover 22, which is equal to the volume of the cavity between the upper cylinder cover 21 and the lower cylinder cover 22.

So, the inside appearance chamber of slump test section of thick bamboo just is by even trisection, because concrete filling in-process need divide the cubic evenly to add, the top of lower cover 22 is added for the first time, the bottom of last cover 21 is added to the second time, the top of last cover 21 is added to the third time, then at every turn the loading process need see through the transparent region in barrel 1 middle section just can observe the loading of concrete, fill the back that finishes, also can be under the condition of observing, utilize the rammer to hit about 25 along the even outside-in of section of thick bamboo wall, observe whether evenly distributed of concrete, after the tamping, it can to trowel.

Specifically, the bottom of lower barrel casing 22 has pedal ring 23 to outside horizontal extension, and pedal ring 23 and lower barrel casing 22 integrated into one piece when filling the concrete into the test section of thick bamboo, are stepped on pedal ring 23 by the people's foot to guarantee relatively fixed between test section of thick bamboo and the bottom plate, the concrete can not reveal from the bottom.

As shown in fig. 2 and fig. 3, in order to fasten the two half cylinders, a clamping strip 4 protruding outward is fixedly disposed at the joint of the two half cylinders, and a clamp 5 is slidably clamped outside the clamping strip 4, so that the two half cylinders are fixed to each other to form a truncated cone cylinder with a closed peripheral side.

In a preferred embodiment, a rubber sealing gasket is fixed on the joint surface of the two protruded clamping strips 4, after the two half cylinders are clamped, the rubber sealing gasket is jointed to achieve a better sealing effect, the section of each clamping strip 4 is set to be rectangular or train track-shaped, the hoop 5 surrounds the outer side of each clamping strip 4 and tightly joints the two clamping strips 4 to enhance the sealing performance, and during installation and disassembly, the hoop 5 is installed and disassembled in a sliding mode along the length direction of each clamping strip 4.

Further, the handle 3 is fixedly installed on the outer side wall of the half cylinder body, and people can conveniently hold the half cylinder body.

So, between concrete filling, the slump that assembles the concrete earlier looks at a section of thick bamboo, laminate the tangent plane of two half barrels, then installation clamp 5, slide on the length direction of card strip 4 with clamp 5 block on card strip 4, with two half barrel rigidity, form a complete test section of thick bamboo, then to filling concrete in the test section of thick bamboo, fill the completion back, dismantle clamp 5, people hold handle 3 and pull two half barrels on the horizontal direction backward drawing, so, peel off the barrel from the concrete awl, the concrete is because of the dead weight produces the slump, subtract the height of the post-collapse concrete with barrel height (300mm), be called the slump.

Combine above embodiment, through setting up two half barrels of equidimension, can realize relatively fixed or break away from through clamp 5 between two half barrels, so, the process of breaking away from after filling finishes, then can remove two half barrels along opposite direction on the horizontal direction, then can break away from with the concrete awl in an instant, can avoid breaking away from the in-process and touch the influence that causes the concrete awl, consequently can guarantee the accuracy of concrete awl slump result, greatly improve the success rate that slump detected.

Although the present invention has been described with reference to the preferred embodiments, it is not intended to be limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the utility model. Therefore, the protection scope of the present invention should be determined by the appended claims.
