[0002] The embedded channel is a concrete embedded part composed of a steel channel and anchor rods. Unlike traditional embedded parts, the T-bolts of the embedded channel can be freely adjusted in the steel channel. Due to its adjustability, the installation process based on the embedded channel saves time and effort, and the economic benefits are particularly outstanding. The embedded channel has a wide range of uses and has a significant impact on the installed components. It will encounter various loads and various forms of damage during use. Its application in many important fields requires extremely strict quality requirements. Therefore, the embedded channel must not have any hidden dangers during the production and installation process, and it is very necessary to perform mechanical testing on the embedded channel before installation.

[0003] The deflection test of the embedded groove is one of the necessary mechanical tests. The deflection test is performed by applying a tensile load at the symmetric center between the two anchor rods. Due to the different models of embedded grooves, the corresponding anchor rod sizes and the distance between the two anchor rods are also different. In the existing technology, when testing the deflection of the embedded groove, various specifications of tooling must be made, which is complicated to install and inefficient, increasing the difficulty and cost of the test, and it is impossible to read the deflection value during the test.

[0025] It should be noted that the following detailed descriptions are all illustrative and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0026] Embodiment 1

[0027] like Figure 1 As shown, this embodiment provides a direct-reading adjustable embedded groove deflection test tool, including a main structure 1 and a digital micrometer assembly 3, the main structure 1 includes a C-shaped groove 12, the top of the C-shaped groove 12 is fixedly connected to the clamping rod 11, the clamping rod 11 is provided with reinforcing ribs inside, and a mounting hole 13 is provided at the bottom, and the digital micrometer assembly 3 is installed on the main structure 1 through the mounting hole 13.

[0028] The digital micrometer assembly 3 includes a micrometer fixing bracket 32, on which a digital micrometer 33 is mounted. A first screw rod 34 is fixedly connected to the top of the micrometer fixing bracket 32, and an adjustable sleeve 31 is threadedly connected to one end of the first screw rod 34 away from the micrometer fixing bracket 32, and a second screw rod 35 is fixedly connected to one end of the adjustable sleeve 21 away from the first screw rod 34, and the second screw rod 35 is threadedly connected to the mounting hole 13. The length of the digital micrometer assembly 3 can be adjusted by rotating the adjustable sleeve 31 to adapt to different lengths of the anchor rod 4.

[0029] The pin of the digital micrometer 33 is pressed against the surface of the embedded groove. The deflection value of the embedded groove can be directly read during the test by the digital micrometer assembly 3, which is simple and convenient, simplifies the test process, and reduces the test cost.

[0030] Both sides of the mounting hole 13 are provided with a slot structure 14, and a clamping mechanism is slidably connected inside the slot structure 14. The bottom of the clamping mechanism is provided with a clamping groove that matches the anchor rod 4 of the embedded channel. The end shape of the anchor rod 4 of the embedded channel of different types is adapted by replacing different clamping mechanisms, and the distance between the two clamping mechanisms is adjusted by sliding the clamping mechanism inside the slot structure 14 to adapt to the anchor rods 4 of different spacings. When measuring different anchor rod 4 spacings and different types of embedded channels, there is no need to replace the test device, which simplifies the test process and improves the test efficiency.

[0031] The clamping mechanism is an anchor rod clamp 2, and the anchor rod clamp 2 includes a toothed T-shaped connector 21 and an anchor rod clamping block 22, and the toothed T-shaped connector 21 is connected to the anchor rod clamping block 22 through an intermediate connecting portion 23. The toothed T-shaped connector 21 includes a horizontal component and a vertical component, the bottom of the vertical component is fixedly connected to the intermediate connecting portion 23, and the top is fixedly connected to the horizontal component, and the two sides of the vertical component form an inverted step structure with the horizontal component. The cross-sectional width of the horizontal component along the horizontal direction is smaller than the width of the slot structure, and its length is greater than the width of the slot structure. It is convenient to put the anchor rod clamp 2 into the slot structure 14 by rotating the toothed T-shaped connector 21, and clamp the slot structure 14 through the inverted step structure.

[0032] The anchor rod clamping block 22 is a cylinder as a whole, and a clamping groove matching the shape of the end of the anchor rod 4 of the embedded channel is provided at its bottom. The intermediate connecting portion 23 is a cylinder, and the diameter of the intermediate connecting portion 23 is smaller than the diameter of the anchor rod clamping block 22, and smaller than the side length of the horizontal component and the vertical component, so that the anchor rod clamp 2 can slide in the slot structure 14 by using the intermediate connecting portion 23 with a small diameter.

[0033] Working principle: When conducting a deflection test on the embedded groove, it is first necessary to select an anchor rod clamp 2 that is compatible with the shape of the end of the anchor rod 4 of the embedded groove to be tested and place it in the groove structure 14. By twisting the toothed T-shaped connector 21, the intermediate connecting part 23 can be rotated relative to the anchor rod clamping block 22, thereby changing the relative position of the toothed T-shaped connector 21 and the anchor rod clamping block 22, so that the transverse part of the toothed T-shaped connector 21 is parallel to the groove structure 14, and the anchor rod clamp 2 is placed in the groove structure 14, so that the intermediate connecting part 23 slides along the groove structure 14 and is positioned to the position of the anchor rod 4 of the embedded groove to be tested. Then, the toothed T-shaped connector 21 is twisted again and rotated 90 degrees so that the transverse part of the toothed T-shaped connector 21 is perpendicular to the groove structure 14, and the anchor rod clamp 2 is pulled toward the outside of the groove structure 14, so that the groove structure 14 clamps the two sides of the vertical part and forms an inverted step with the transverse part. The slot structure 14 is provided with teeth along the slot and the edge of the transverse part of the toothed T-type connector 21, which can increase the friction force and prevent the slot structure 14 and the anchor rod clamp 2 from sliding relative to each other. After the anchor rod clamps 2 on both sides clamp the anchor rod 4 of the embedded groove to be tested, the length of the digital micrometer assembly 3 can be adjusted by rotating the adjustable sleeve 31 to adapt it to the length of the anchor rod 4 of the embedded groove to be tested. Make the thimble of the digital micrometer 33 stand against the surface of the embedded groove, adjust the appropriate reading and reset it. Then, a tensile force can be applied to both ends of the T-bolt 5 and the clamping rod 11 to perform a deflection test, and read the value of the digital micrometer 33.

[0034] When it is necessary to detect embedded grooves of different types, due to the different shapes and sizes of the ends of the anchor rods 4, it is necessary to replace the anchor rod clamp 2. First, push the anchor rod clamp 2 toward the inside of the slot structure 14 to make the slot structure 14 slide from the inverted step to the middle connecting part 23, then twist the toothed T-shaped connector 21 and rotate it 90 degrees so that the transverse part of the toothed T-shaped connector 21 is parallel to the slot structure 14, and then remove the anchor rod clamp 2 for replacement.

[0035] When the shape and size of the end of the anchor rod 4 remain unchanged, but the clamping spacing of the anchor rod 4 is different, it is only necessary to change the relative distance between the two anchor rod clamps 2. First, push the anchor rod clamp 2 toward the inner direction of the slot structure 14, so that the slot structure slides from the inverted step to the middle connecting part 23, and slides in the slot structure 14 using the middle connecting part 23 with a smaller diameter, and after locating the position of the anchor rod 4 of the embedded groove to be inspected, pull the anchor rod clamp 2 toward the outer direction of the slot structure 14, so that the slot structure 14 clamps the two sides of the vertical component and forms an inverted step with the horizontal component.

[0036] In this embodiment, the anchor rod clamping block 2 can be constructed in any suitable shape to adapt to different use environments and expand the scope of use. The shape of the clamping groove at the bottom is also adapted to the end shape of the anchor rod 4 of the different embedded grooves to be detected. For example, when the upper end of the anchor rod 4 is constructed in a T-shape, the clamping groove is constructed as an adapted T-slot.

[0037] The utility model provides a direct-reading adjustable embedded groove deflection test tool, which has a simple overall structure and a scientific and reasonable design. It can clamp embedded grooves of different models and anchor rods with different spacings. The deflection value can be read during the test, which simplifies the test process and reduces the test cost.

[0038] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
