Abstract
Description
Technical Field
[0001] This application relates to the field of mortar bond strength testing technology, and in particular to a lightweight mortar bond strength field testing fixture system. Background Technology
[0002] The tensile bond strength of building mortar is an important indicator for evaluating its performance. This indicator not only affects the reliability of mortar in practical applications, but is also a key parameter for evaluating the quality of building mortar. When testing the bond strength of mortar, it is necessary to use a strength testing fixture to assist in the testing operation.
[0003] While existing mortar bonding strength testing fixtures can effectively fix the test block placement plate, they often rely on manual adjustment and fixation around the test block placement plate. This results in poor automatic adjustment and fixation around the placement plate, limited multi-directional positioning and fixation, and inadequate adjustment and positioning for placement plates of different widths. Consequently, the fixtures become less efficient at adjusting and testing placement plates of different sizes. Utility Model Content
[0004] This application provides a lightweight mortar bonding strength field testing fixture system to solve the problems that the test block placement plate is usually adjusted and fixed manually, which has poor automatic adjustment and fixing effect on the four sides of the placement plate, poor multi-directional limiting and fixing effect on the placement plate, and poor adjustment and limiting effect on placement plates of different widths.
[0005] This application provides a lightweight mortar bonding strength on-site testing fixture system, including a fixture body, an adjusting rod slidably connected to the outer wall of the fixture body, a connecting frame fixedly connected to the top of the adjusting rod, a testing machine body slidably connected to the outer wall of the connecting frame, a pull-out block telescopically connected to the outer wall of the testing machine body, a sample placement plate placed on the outer wall of the fixture body, a test block located below the pull-out block adhered to the outer wall of the sample placement plate, a threaded slider slidably connected to the outer wall of the fixture body, a clamping rod located on one side of the sample placement plate fixedly connected to the outer wall of the threaded slider, and a connecting block slidably connected to the outer wall of the fixture body at one end of the clamping rod.
[0006] Preferably, there are two sets of sample placement plates, and the positions of the two sets of sample placement plates are symmetrical about the central axis of the fixture body. The test block is distributed in a straight line on the outer wall of the sample placement plate.
[0007] Preferably, the movement trajectory of the pulling block is cross-shaped.
[0008] Preferably, a servo motor is provided on the outer wall of the fixture body, and the output end of the servo motor is fixedly connected to a threaded rod that is threadedly connected to the outer wall of the threaded slider.
[0009] Preferably, the threaded rod is provided in two sets, and the two sets of threaded rods rotate in opposite directions.
[0010] Preferably, the outer wall profile of the clamping rod is L-shaped.
[0011] Preferably, a fixing groove is provided at the connection between the outer wall of the clamp body and the threaded slider, and a connecting groove is provided at the connection between the outer wall of the clamp body and the connecting block.
[0012] Beneficial effects:
[0013] While existing mortar bonding strength testing fixtures can effectively fix the test block placement plate, they often rely on manual adjustment and fixation around the test block placement plate. This results in poor automatic adjustment and fixation around the placement plate, limited multi-directional positioning and fixation, and inadequate adjustment and positioning for placement plates of different widths. Consequently, the fixtures become less efficient at adjusting and testing placement plates of different sizes.
[0014] When it is necessary to improve the adjustment and fixation of mortar placement plates of different sizes in different positions using a fixture, the sample placement plate is placed on the surface of the fixture body, and the servo motor is turned on. The rotation of the threaded rod drives the threaded slider to slide along the inner wall of the fixing groove, and drives the clamping rod to slide synchronously. At the same time, under the connection of the clamping rod, the connecting block is driven along the inner wall of the connecting groove. This allows the placement plate to be clamped and fixed in different positions under the centering sliding of the clamping rod, and achieves the effect of adjusting and limiting the placement plates of different widths, thereby improving the efficiency of mortar bonding strength testing.

[0029] This utility model provides, for example Figure 1-4 The lightweight mortar bonding strength field testing fixture system shown includes a fixture body 1, an adjusting rod 2 slidably connected to the outer wall of the fixture body 1, a connecting frame 3 fixedly connected to the top of the adjusting rod 2, a testing machine body 4 slidably connected to the outer wall of the connecting frame 3, a pulling block 5 telescopically connected to the outer wall of the testing machine body 4, a sample placement plate 6 placed on the outer wall of the fixture body 1, a test block 7 located below the pulling block 5 adhered to the outer wall of the sample placement plate 6, a threaded slider 10 slidably connected to the outer wall of the fixture body 1, a clamping rod 12 located on one side of the sample placement plate 6 fixedly connected to the outer wall of the threaded slider 10, and a connecting block 13 slidably connected to the outer wall of the fixture body 1 at one end of the clamping rod 12.
[0030] Among them, there are two sets of sample placement plates 6, and the positions of the two sets of sample placement plates 6 are symmetrical about the central axis of the fixture body 1. The test block 7 is distributed in a straight line on the outer wall of the sample placement plate 6.
[0031] This allows the test blocks 7 to be arranged in a straight line on the outer wall of the sample placement plate 6, thereby increasing the number of mortar tests.
[0032] The movement trajectory of the pulling block 5 is cross-shaped.
[0033] This allows for testing each mortar test block individually by setting the movement trajectory of the pull block 5 in a cross shape.
[0034] The outer wall of the fixture body 1 is provided with a servo motor 8, and the output end of the servo motor 8 is fixedly connected to a threaded rod 9 that is threadedly connected to the outer wall of the threaded slider 10.
[0035] The threaded rod 9 is designed to drive the threaded slider 10 to slide.
[0036] The threaded rod 9 is provided in two sets, and the two sets of threaded rod 9 rotate in opposite directions.
[0037] This allows for the relative sliding of two sets of threaded sliders 10 by setting two sets of threaded rods 9 with opposite rotation directions.
[0038] The outer wall contour of the clamping rod 12 is L-shaped.
[0039] The L-shaped outer contour of the clamping rod 12 facilitates the improvement of synchronous positioning of the placement plate in different orientations.
[0040] The outer wall of the clamp body 1 is provided with a fixing groove 11 at the connection between the outer wall of the clamp body 1 and the threaded slider 10, and the outer wall of the clamp body 1 is provided with a connecting groove 14 at the connection between the outer wall of the clamp body 1 and the connecting block 13.
[0041] The setting of the fixing groove 11 and the connecting groove 14 is conducive to achieving the effect of limiting the sliding of the clamping rod 12.
[0042] Working principle: When using this lightweight mortar bonding strength field testing fixture system, to improve the adjustment and fixation of mortar placement plates of different sizes in different positions, the sample placement plate 6 is placed on the surface of the fixture body 1, and the servo motor 8 is turned on. Through the rotation of the threaded rod 9, the threaded slider 10 is driven to slide along the inner wall of the fixing groove 11, and the clamping rod 12 is driven to slide synchronously. At the same time, under the connection of the clamping rod 12, the connecting block 13 is driven along the inner wall of the connecting groove 14, so that under the centering sliding of the clamping rod 12, the placement plate is clamped and fixed in different positions, and the effect of adjusting and limiting the placement plate of different widths is achieved, thereby improving the efficiency of mortar bonding strength testing.
[0043] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
