Description

Technical Field

[0001] The utility model relates to a building material performance test, in particular to a device for testing the seepage performance of mortar under gravity. Background Art

[0002] Cracks are a common quality problem in construction projects. Their appearance will affect the safety performance and normal use of the project structure. In crack repair operations, the gravity penetration method is often used to directly use mortar repair materials to treat cracks. At present, there is no special report on the test method for the depth of mortar penetration into cracks. The industry usually uses mortar fluidity test to indicate the quality of mortar fluidity, but this test cannot intuitively reflect the maximum depth of the crack that the mortar can flow through under its own weight, so it is difficult to use it to guide the selection of mortar when repairing cracks.

DETAILED DESCRIPTION

[0023] The following will describe the implementation of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention, not for limiting the scope of protection of the present invention.

[0024] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0025] In one embodiment, see Figure 1 As shown, a device for testing the seepage performance of mortar under the action of gravity is provided, comprising a shell 1, a receiving chamber 2 and a test chamber 3 arranged in the shell 1, wherein the receiving chamber 2 is located above the test chamber 3, and a partition component 5 for switching on and off between the receiving chamber 2 and the test chamber 3 is also connected in the shell 1. The receiving chamber 2 is used to receive the mortar 7 to be tested, and the test chamber 3 is filled with a plurality of rigid beads 4 or rigid particles. During the test, the partition component 5 is opened to connect the receiving chamber 2 and the test chamber 3, and the mortar 7 to be tested in the receiving chamber 2 seeps into the pores between the rigid beads 4 or rigid particles in the test chamber 3 under the action of gravity, and the seepage performance of the mortar is characterized by the seepage depth of the mortar 7 to be tested in the test chamber 3 filled with rigid beads 4 or rigid particles. The device has a simple structure and is easy to operate, and can quickly determine the seepage performance of the mortar.

[0026] In one embodiment, the housing 1 includes an upper cylinder 11 and a lower cylinder 12 that are detachably connected. The upper cylinder 11 is provided with a receiving chamber 2 , and the lower cylinder 12 is provided with a testing chamber 3 .

[0027] Such an arrangement makes it easy to load and unload the housing 1, and can quickly switch the upper cylinder 11 and / or the lower cylinder 12 of different sizes and models according to actual test requirements, which is convenient and quick.

[0028] For example, see Figure 2 As shown, the upper cylinder 11 and the lower cylinder 12 are detachably connected by a first fastener 8. Specifically, a first lug 111 extending radially outward is provided at the lower end of the upper cylinder 11, and a second lug 121 extending radially outward is provided at the upper end of the lower cylinder 12. Both the first lug 111 and the second lug 121 are provided with through holes for allowing the first fastener 8 to pass through. During installation, the first lug 111 on the upper cylinder 11 is aligned with the second lug 121 on the lower cylinder 12, and the first lug 111 and the second lug 121 are fixedly connected by the first fastener 8. The first fastener 8 can be a bolt and a nut.

[0029] For example, see Figure 3 As shown, the upper cylinder 11 and the lower cylinder 12 are detachably connected by a snap connection. Specifically, a snap connection sink is provided at the lower end of the upper cylinder 11, and a snap connection protrusion corresponding to the snap connection sink is provided at the upper end of the lower cylinder 12.

[0030] Since the lower cylinder 12 and the upper cylinder 11 are connected in a detachable manner, the upper part of the lower cylinder 12 can be set to an open form, which is convenient for quickly replacing rigid beads 4 or rigid particles of different particle sizes to meet more mortar seepage performance test requirements and has a wider range of applications.

[0031] As a preferred implementation of this embodiment, see Figure 4 As shown, the lower cylinder 12 includes a detachably connected left half 122 and a right half 123. Exemplarily, the left half 122 and the right half 123 are detachably connected by a second fastener 9. After the test is completed, the connection between the upper cylinder 11 and the lower cylinder 12 is first separated, and then the connection between the left half 122 and the right half 123 is separated, so that the rigid beads 4 or rigid particles in the test cavity 3 can be taken out for cleaning, so that the rigid beads 4 or rigid particles can be reused, reducing the test cost.

[0032] In one embodiment, see Figure 1As shown, the particle size of the rigid beads 4 or rigid particles is 5 to 40 mm. Reasonable particle size setting ensures that the mortar can neither penetrate into the bottom of the device nor penetrate into the rigid particles with difficulty, thereby making it easier to distinguish the mortar seepage performance. For example, the test cavity 3 is filled with rigid beads with a particle size of 10 mm.

[0033] In one embodiment, see Figure 3 As shown, the area at the lower part of the shell 1 corresponding to the test cavity 3 is a transparent part, and a plurality of indicator lines 13 are provided at the lower part of the shell 1 corresponding to the test cavity 3. In this way, the seepage depth of the mortar 7 to be tested in the test cavity 3 filled with rigid beads 4 or rigid particles can be obtained by visual observation, and the seepage performance of the mortar can be quickly determined.

[0034] In one embodiment, see Figure 5 As shown, the partition assembly 5 is a plate body 51 radially slidably connected between the accommodating chamber 2 and the test chamber 3. When in use, the plate body 51 is radially slid into the accommodating chamber 2 and the test chamber 3 along the shell 1 to separate the accommodating chamber 2 and the test chamber 3, and then the mortar 7 to be tested is added into the accommodating chamber 2. After the amount of mortar 7 to be tested reaches a preset value, the plate body 51 is radially slid out of the shell 1, so that the accommodating chamber 2 and the test chamber 3 are connected, and the mortar 7 to be tested in the accommodating chamber 2 seeps into the pores between the rigid beads 4 or rigid particles in the test chamber 3 under the action of gravity, and the seepage performance of the mortar is characterized by the seepage depth of the mortar 7 to be tested in the test chamber 3 filled with rigid beads 4 or rigid particles.

[0035] As a preferred implementation of this embodiment, in order to facilitate operation, a handle 52 is fixed to the end of the plate body 51 away from the housing 1 .

[0036] As a preferred implementation of this embodiment, see Figure 3 As shown, a support flange 112 extending radially inward is provided on the inner side of the lower end of the upper cylinder 11 to support the plate body 51 and prevent the plate body 51 from falling.

[0037] In one embodiment, the partition assembly 5 is an on-off valve connected to the housing 1 , and the connection or disconnection between the accommodating chamber 2 and the testing chamber 3 is achieved by opening and closing the on-off valve.

[0038] In some embodiments, see Figure 6 As shown, the partition assembly 5 includes a fixed plate 53, a movable plate 54 and an operating rod 55. The outer edge of the fixed plate 53 is fixedly connected to the inner wall of the housing 1, the movable plate 54 is movably connected to the bottom of the fixed plate 53, and the lower end of the operating rod 55 passes through the fixed plate 53 and is fixedly connected to the movable plate 54;

[0039] The fixing plate 53 has a first mounting hole 532 in the middle for the operating rod 55 to pass through, and a plurality of first through holes 531 are arranged around the first mounting hole 532. For example, there are four first through holes 531, which are evenly distributed around the first mounting hole 532.

[0040] A second mounting hole 542 fixedly connected to the operating rod 55 is provided in the middle of the movable plate 54 , and a second through hole 541 is provided around the second mounting hole 542 at a position corresponding to the first through hole 531 on the fixed plate 53 .

[0041] The movable plate 54 is driven to rotate relative to the fixed plate 53 by rotating the operating rod 55. When the first through hole 531 and the second through hole 541 coincide or partially coincide, the accommodating chamber 2 is connected with the test chamber 3; when the first through hole 531 and the second through hole 541 are offset, the accommodating chamber 2 is disconnected from the test chamber 3.

[0042] Such a configuration has a simple structure, is convenient and quick to operate, and facilitates rapid connection or disconnection of the accommodating chamber 2 and the testing chamber 3 .

[0043] In one embodiment, the upper end of the housing 1 is provided with an opening communicating with the accommodating chamber 2, and a cover plate 6 is connected to the opening. When in use, the cover plate 6 is opened, and the mortar 7 to be tested is added into the accommodating chamber 2 at the upper part of the housing 1.

[0044] The above embodiments are only preferred embodiments for fully illustrating the present invention, and the protection scope of the present invention is not limited thereto. Any equivalent substitution or modification made by a person skilled in the art based on the present invention is within the protection scope of the present invention.
