Description

Technical Field

[0001] This utility model relates to the technical field of concrete mixture spread measurement tools, and in particular to an auxiliary measuring device for concrete mixture spread. Background Technology

[0002] The spreadability of concrete mixtures is an important indicator of their workability. Standards stipulate that during the spreadability test, after the concrete mixture stops spreading or has continued spreading for a predetermined time, the maximum diameter of the spread surface and the diameter perpendicular to the maximum diameter should be measured using a steel ruler, and their average value should be taken as the spreadability test result. However, in actual testing, there are protrusions in the middle of the spread concrete, and the concrete surface is uneven. This means that relying solely on visual inspection and a steel ruler is insufficient to accurately locate the spread boundary. Furthermore, it is difficult to ensure the steel ruler is level during testing, leading to inaccurate results. Additionally, after measuring the maximum diameter, its vertical position cannot be accurately determined, resulting in significant uncertainty in the test results. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an auxiliary measuring device for the spread of concrete mixture in order to overcome the shortcomings of the existing technology.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a concrete mixture expansion auxiliary measuring device, including a transverse positioning device and a longitudinal positioning device. The transverse positioning device includes a horizontal bar, one end of which is provided with a fixed bar, and the other end of which is slidably connected with a first sliding bar. The fixed bar and the first sliding bar are both arranged perpendicularly to the horizontal bar.

[0005] A slider is slidably connected to the center of the crossbar, the vertical section of the slider is perpendicular to the crossbar, and a slot is provided on the slider;

[0006] The longitudinal positioning device includes a longitudinal rod that passes through the slot, and both ends of the longitudinal rod are slidably connected to a second sliding rod.

[0007] By adopting the above technical solution, the horizontal positioning device is fixed at one end and moves freely at the other end. The maximum diameter boundary is quickly located by the fixed rod and the sliding rod. At the same time, since the horizontal bar is suspended above the concrete mixture, its level is controlled by the fixed rod and the sliding rod. The protruding concrete mixture will not affect the level of the bar. After the maximum diameter boundary is located, the length of the horizontal bar between the fixed rod and the sliding rod can be measured with a steel ruler to prepare for obtaining the maximum diameter.

[0008] At the same time, the longitudinal positioning device is quickly connected to the slot. The slider ensures that the longitudinal positioning device moves perpendicular to the crossbar, thereby quickly positioning the diameter perpendicular to the maximum diameter. The length of the longitudinal rod between the two longitudinal sliding rods is measured with a steel ruler to obtain the diameter perpendicular to the maximum diameter.

[0009] Furthermore, the left and right ends of the opening of the slot described in this utility model are connected to limit blocks by springs;

[0010] By adopting the above technical solution, the longitudinal rod can be easily connected and disconnected under the action of external force. Not only can the slider be moved by pushing the longitudinal rod, but it can also be prevented from coming out of the slot under the weight of the longitudinal rod itself, which is very convenient.

[0011] Furthermore, the fixing rod described in this utility model has a hollow structure, and a fixing stake is installed inside the fixing rod to facilitate ground fixing.

[0012] Furthermore, the top of the fixed pile described in this utility model is provided with a circular force-bearing flat cap, which facilitates fixing by hammering when necessary.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model introduces a transverse positioning device with one end fixed and the other end freely movable. The maximum diameter boundary is quickly located by means of a fixed rod and a sliding rod. By suspending the structure, the length of the horizontal bar between the fixed rod and the sliding rod can be measured with a steel ruler to prepare for obtaining the maximum diameter.

[0015] 2. By introducing a slider, the longitudinal positioning device is ensured to move perpendicular to the crossbar, thereby quickly positioning the diameter perpendicular to the maximum diameter. The length of the longitudinal rod between the two longitudinal sliding rods is measured with a steel ruler to obtain the diameter perpendicular to the maximum diameter, thus solving the problem that conventional measurement cannot accurately locate the diameter perpendicular to the maximum diameter.

[0016] 3. By introducing a slider with one open end, the longitudinal positioning device can be easily placed or removed. After testing, the lateral and longitudinal positioning devices can be placed in parallel, reducing the space occupied by the device and making it easy to store. Attached Figure Description

[0023] like Figure 1 The present invention is an auxiliary measuring device for the spreadability of concrete mixture, including a transverse positioning device and a longitudinal positioning device. The transverse positioning device includes a horizontal bar 1, one end of which is provided with a fixed bar 2, and the other end of which is slidably connected with a first sliding bar 3. The fixed bar 2 and the first sliding bar 3 are both arranged perpendicularly to the horizontal bar 1.

[0024] A slider 4 is slidably connected to the center of the crossbar 1. The vertical section of the slider 4 is perpendicular to the crossbar 1, and a slot 5 is provided on the slider 4.

[0025] The longitudinal positioning device includes a longitudinal rod 6 that passes through the slot 5, and a second sliding rod 7 is slidably connected to both ends of the longitudinal rod 6.

[0026] The opening of the slot 5 is connected to limit stops 9 by springs 8 at both ends. The fixing rod 2 is a hollow structure, and a fixing post 10 is installed inside the fixing rod 2. A circular force-bearing cap 11 is provided at the top of the fixing post 10.

[0027] Working principle:

[0028] The fixed rod at one end of the horizontal positioning device is fixed at the end of the maximum diameter of the diffused concrete. The maximum diameter boundary is quickly located by the sliding rod. At the same time, since the horizontal bar is suspended above the concrete mixture, its level is controlled by the fixed rod and the sliding rod. The concrete mixture protruding in the middle will not affect the level of the horizontal bar. After the maximum diameter boundary is located, the length of the horizontal bar between the fixed rod and the sliding rod can be measured with a steel ruler to prepare the maximum diameter.

[0029] Next, the longitudinal rod of the longitudinal positioning device is quickly connected to the slot. The slider ensures that the longitudinal positioning device moves perpendicular to the crossbar, thereby quickly positioning the diameter perpendicular to the maximum diameter. The length of the longitudinal rod between the two longitudinal sliding rods is measured with a steel ruler to obtain the diameter perpendicular to the maximum diameter.

[0030] After the measurement is completed, forcefully remove the longitudinal rod from below the slot for easy storage.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
