Description

Technical Field

[0001] This utility model relates to the technical field of concrete performance testing equipment, and in particular to a digital direct-reading slump measuring bucket. Background Technology

[0002] Slump refers to the workability of concrete, including its water retention, fluidity, and cohesiveness. Good workability directly affects the construction process and uniform compaction of concrete. Concrete slump is influenced by many factors such as mix proportions, admixtures, transportation distance, and climatic conditions. During construction, a suitable slump must be selected based on the construction location, pouring method, and technological requirements to ensure smooth pouring and construction quality. For some construction locations, such as underwater concrete pouring for bored piles, or pouring methods such as truck-mounted concrete pumping or high-rise concrete pumping, the slump requirements before pouring are more stringent, and slump control is particularly important, directly affecting the smoothness of the concrete pouring process and the guarantee of construction quality.

[0003] Currently, the slump measuring instruments used in engineering all use steel rulers for reading, which is inconvenient to use and results in large measurement errors.

[0004] Therefore, it is necessary to develop a digital direct-reading slump measurement bucket to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to design a digital direct-reading slump measuring bucket to solve the above problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] A digital direct-reading slump measuring bucket, comprising:

[0008] funnel;

[0009] Slump cone; the slump cone is connected to the bottom of the funnel;

[0010] Slide chute; The slide chute is horizontally installed on the upper side wall of the slump bucket, and an observation slot is provided inside the slide chute along its length.

[0011] Laser rangefinder; the laser rangefinder can be slidably placed in a groove and measures vertically downwards.

[0012] The beneficial effects of this utility model are as follows:

[0013] The chute is horizontally installed on the upper side wall of the slump bucket. The laser rangefinder is housed in the chute and can slide along the length of the chute. When measuring data, the laser rangefinder is moved directly to the highest point of the slumped concrete to read the slump value corresponding to that highest point. The measurement is convenient, quick, and the data is accurate.

[0014] In addition, this application has a simple structure, is easy to manufacture, has low cost, is convenient to use, and has an overall beautiful appearance. The digital direct-reading design not only provides convenience for the production, transportation and sales of slump measuring instruments, but also for their use on construction sites.

[0028] Funnel 1;

[0029] Slump bucket 2; Slump bucket 2 is connected to the lower opening of funnel 1 (funnel 1 can be used only temporarily with its lower opening aligned with the upper opening of slump bucket 2, and can be held by hand); Funnel 1 and slump bucket 2 are both frustum-shaped structures, and the axis of funnel 1 is set to coincide with the axis of slump bucket 2.

[0030] Slide 5; Slide 5 is horizontally installed on the upper side wall of slump bucket 2. An observation slot 53 is provided in slide 5 along its length. Slide 5 includes an outer wall 51 and two sliding plates 52. The outer wall 51 is formed into a rectangular ring structure. The two sliding plates 52 are horizontally installed on the long side of the inner side of the outer wall 51. The length of the sliding plates 52 is the same as the length of the long side of the inner side of the outer wall 51. The two sliding plates 52 are set at the same height. The observation slot 53 is set between the two sliding plates 52. The laser rangefinder 4 is slidably placed inside the outer wall 51 and above the two sliding plates 52.

[0031] Laser rangefinder 4; Laser rangefinder 4 is slidably placed in the slide groove 5 and measures vertically downward; The measurement zero point of laser rangefinder 4 is the top height position of slump bucket 2;

[0032] Mounting seat 7; Mounting seat 7 is installed on the upper side wall of slump bucket 2. Mounting seat 7 has a horizontally provided mounting groove, and one end of sliding groove 5 is inserted into the mounting groove.

[0039] 3. Quickly pull up the slump bucket 2 and let the concrete collapse freely. After the collapse stabilizes, place the slump bucket 2 on the ground. Then move the laser rangefinder 4 along the length of the chute 5 until it is above the highest point of the collapsed concrete. Read the value corresponding to the laser rangefinder 4 at this time, which is the measured concrete slump.

[0040] 4. After the test is completed, clean the slump bucket 2 and funnel 1 to ensure that the instruments are clean, and store and preserve the instruments in a unified manner.
