Problems solved by technology

If it is not cleaned, it will affect the final weighed quality, which will greatly affect the accuracy of the apparent density result
However, cleaning the mortar on the outer surface of the container increases the loss of manpower and material resources, making the process of the apparent density test more complicated

Embodiment 1

[0043] Such as Figure 1 to Figure 2 As shown, an auxiliary device for measuring the apparent density of mortar, including a central annular vertical compression plate 1 tightly sleeved on the mouth of the apparent density barrel, and an outer edge of the central annular vertical compression plate 1 An annular material collection device, the bottom of the material collection device is symmetrically provided with a clamping device for clamping the outer peripheral wall of the apparent density barrel.

[0044] The material collection device includes a peripheral annular vertical baffle 3 located around the central annular vertical compression plate 1, which is connected to the outer edge of the central annular vertical compression plate 1 and the peripheral annular vertical baffle at a certain angle inclined outwards. To the inclined ring plate 2 between the baffles 3 .

[0045] The clamping device includes a support rod 5 that is symmetrically hinged at the bottom of the mater...

Embodiment 2

[0056] Such as image 3 As mentioned above, the difference between this embodiment and Embodiment 1 is that the support rod 5 is T-shaped and hinged to the bottom of the inclined circular plate 2 through a rebound device 4, which has a simple structure and is easy to install.

Embodiment 3

[0058] Such as Figure 4As mentioned above, the difference between this embodiment and Embodiment 1 is that: the support rod 5 is I-shaped, and is hinged to the bottom of the inclined circular plate 2 through two rebound devices 4 .

Abstract

The invention discloses an auxiliary device for measuring mortar apparent density. The auxiliary device comprises a central annular vertical compression plate and an annular material collection device, the central annular vertical compression plate compactly sleeves an opening of an apparent density barrel, the annular material collection device is arranged at the outer edge of the central annular vertical compression plate, and clamping devices for clamping the peripheral wall of the apparent density barrel are symmetrically arranged at the bottom of the material collection device. The invention further provides a method for measuring the mortar apparent density. The device has the advantages of simple construction and convenience in operation, waste caused by scraping of surplus mortar is removed, complex steps cleaning the wall of the apparent density barrel are removed, and accuracy of final test results is ensured.

Description

technical field [0001] The invention belongs to the field of concrete property test experiments, in particular to an auxiliary device and method for measuring the apparent density of mortar. Background technique [0002] The mortar apparent density test is widely used as one of the basic performance testing tests of mortar. At present, there is a 1L container used to measure the apparent density of mortar. According to the "Standards for Basic Performance Tests of Building Mortar" (JGJ / T70-2009), after adding mortar to the container and vibrating it for compaction, it is necessary to scrape off the excess mortar on the surface. However, in the process of scraping, excess mortar will adhere to and remain on the outer surface of the container. If it is not cleaned, it will have an impact on the final weighed quality, which in turn will greatly affect the accuracy of the apparent density result. However, cleaning the mortar on the outer surface of the container increases the ...
