Description

Technical Field

[0001] The invention relates to the technical field related to grouting sleeves, and in particular to a tension and compression test device and a test method for a grouting sleeve. Background Art

[0002] As one of the basic industries of my country's national economy, the construction industry has been showing a trend of vigorous development. In recent years, with the increasing advancement of my country's industrialization process, prefabricated buildings have been vigorously developed. They are energy-saving and environmentally friendly, simple and efficient construction, and low labor demand. They are the main direction of modern construction development. Prefabricated buildings use standardized and modular components and are assembled on site, which greatly shortens the construction period and improves construction efficiency. Especially in large-scale projects such as high-rise buildings, bridges, and factories, prefabricated structures play an important role.

[0003] For prefabricated structures, effective connection between components is a necessary prerequisite for structural safety. Reliable connection of steel bars is the most important in component connection. In order to ensure the reliability of steel bar connection, a variety of connection methods have been developed and applied. Among them, sleeve grouting connection technology is easy to operate, has excellent mechanical properties, wide applicability and low cost. Therefore, sleeve grouting connection technology is widely used in prefabricated buildings.

[0004] The indicators for judging the connection performance of grouting sleeves include: tensile and compressive strength, seismic performance, durability, etc. Among them, tensile and compressive strength is the most commonly used core indicator for evaluating the connection performance of grouting sleeves. Tensile and compressive strength usually requires that the connection strength in the grouting connection performance reaches more than 85% of the design value, and no cracks or damage should occur to ensure the reliability of the connection.

[0005] Although the grouting sleeve connection technology has been widely used, the existing tensile and compression test devices for steel bar grouting sleeve connections still have some limitations in the cyclic tension and compression tests conducted in the laboratory: the structure of the common tension and compression test devices is relatively complex, and the fixing of the steel bars, positioning of the sleeves and grouting operations are cumbersome, resulting in a long test preparation time and reduced test efficiency. The existing tension and compression test devices require multiple processes during assembly and disassembly, which is not conducive to completing multiple tests quickly and efficiently. In particular, when the existing tension and compression test devices conduct tension and compression tests on the grouting sleeves, most of the time, the steel bars need to be welded to the steel plate before the test is carried out, and the steel bars need to be cut during disassembly, resulting in complex test steps and safety hazards.

[0006] Therefore, the tensile and compressive test device of the grouting sleeve in the prior art has the problems of complicated disassembly and assembly test steps and low efficiency. Summary of the invention

[0007] The purpose of the present invention is to solve the problems of complicated disassembly and assembly test steps and low efficiency in the tensile and compressive test device of the grouting sleeve in the prior art.

[0008] To solve the above technical problems, an embodiment of the present invention discloses a tensile and compressive test device for a grouting sleeve, comprising a device bracket, on which a first mounting mechanism and a second mounting mechanism are arranged at intervals, and the two ends of the grouting sleeve to be tested are respectively detachably fixed to the first mounting mechanism and the second mounting mechanism.

[0009] The first mounting mechanism is arranged on one side of the device bracket and is transmission-connected to the power output end of the hydraulic drive component on the device bracket. The first mounting mechanism includes a first main mounting plate and a first fixed anchor group. The first main mounting plate is fixedly connected to the power output end. A first mounting groove is arranged on the first main mounting plate. The first mounting groove extends inward from one side edge of the first main mounting plate and penetrates part of the first main mounting plate. One end of the grouting sleeve to be tested extends into the first mounting groove and is moved and installed along the first mounting groove. The first fixed anchor group is arranged at one end of the grouting sleeve extending out of the first main mounting plate to fix one end of the grouting sleeve to the first main mounting plate.

[0010] The second mounting mechanism is located on the other side of the device bracket away from the hydraulic drive component and is detachably connected to the other end of the grouting sleeve, wherein the second mounting mechanism includes a second main mounting plate and a second fixing anchor group, the second main mounting plate is fixedly arranged on the device bracket and is provided with a second mounting groove, the second mounting groove extends inward from one side edge of the second main mounting plate and penetrates part of the second main mounting plate, the other end of the grouting sleeve extends into the second mounting groove and is moved and installed along the second mounting groove, the second fixing anchor group is arranged at the other end of the grouting sleeve extending out of the second main mounting plate, and fixes the other end of the grouting sleeve to the second main mounting plate.

[0011] By adopting the above technical scheme, during the test process of the tension and compression test device for the grouting sleeve disclosed in the present invention, the two ends of the grouting sleeve to be tested can be detachably and quickly and conveniently installed on the first installation mechanism and the second installation mechanism. Specifically, the first main installation plate on the first installation mechanism has a first installation groove for installing the grouting sleeve, and the second main installation plate on the second installation mechanism has a second installation groove for installing the grouting sleeve. When installing the grouting sleeve, the two ends of the grouting sleeve are inserted into the first installation groove and the second installation groove, and then fixed by the first fixing anchor group and the second fixing anchor group respectively, which simplifies the installation and disassembly process of the device, making the installation and adjustment of the grouting sleeve faster during the test preparation process, shortening the test preparation time. The device can accurately evaluate the performance of the grouting sleeve under tension and pressure, providing reliable data support for engineering applications.

[0012] An embodiment of the present invention also discloses a tensile and compressive test device for a grouting sleeve, wherein the first mounting mechanism also includes a first adjusting portion detachably arranged on one end portion of the grouting sleeve, the first adjusting portion includes a first adjusting screw and two first rotating threaded pressure plates adjustably mounted on the first adjusting screw, the two first rotating threaded pressure plates are arranged at intervals, the outer wall portion of the first adjusting screw is provided with an external thread, the inner wall portion of each first rotating threaded pressure plate is provided with an internal thread matching the external thread, and the end portion of a first rotating threaded pressure plate close to the grouting sleeve can be plugged into one end portion of the grouting sleeve.

[0013] The second mounting mechanism also includes a second adjusting portion detachably arranged on the other end portion of the grouting sleeve, the second adjusting portion includes a second adjusting screw and two second rotating threaded pressure plates adjustably mounted on the second adjusting screw, the two second rotating threaded pressure plates are arranged at intervals, the outer wall portion of the second adjusting screw is provided with an external thread, the inner wall portion of each second rotating threaded pressure plate is provided with an internal thread matching the external thread, and a second rotating threaded pressure plate close to the grouting sleeve is plugged and fixed to the other end portion of the grouting sleeve.

[0014] By adopting the above technical solution, the first adjustment part is set to extend the distance between the top of the first fixed anchor group and the hydraulic drive component. When conducting the compressive strength test of the grouting sleeve connector, the two first rotating threaded pressure plates are rotated so that the top of one of the first rotating threaded pressure plates is tightly attached to the bottom of the power output end of the hydraulic drive component. The compression torque of the hydraulic drive component is directly transmitted to the grouting sleeve, thereby achieving effective pressurization of the grouting sleeve.

[0015] Furthermore, the present invention also discloses a test method for a tensile and compressive test device for a grouting sleeve applied to any one of the above items, the method comprising:

[0016] S1. Move the two ends of the grouting sleeve to be tested from the first mounting slot of the first main mounting plate and the second mounting slot of the second main mounting plate respectively, and make the two ends of the grouting sleeve located in the middle of the first main mounting plate and the second main mounting plate.

[0017] S2. Fix one end of the grouting sleeve extending out of the first main mounting plate by a first fixing anchor group; and fix one end of the grouting sleeve extending out of the second main mounting plate by a second fixing anchor group.

[0018] S3. Fix the first auxiliary mounting plate and the second auxiliary mounting plate to one side of the first main mounting plate and the second main mounting plate respectively, and the first auxiliary mounting plate and the second auxiliary mounting plate respectively cover a part of the first mounting groove and a part of the second mounting groove.

[0019] S4. The power output end of the hydraulic drive component drives the first installation mechanism and one end of the steel bar of the grouting sleeve to move back and forth and perform a tensile test or a compression test.

[0020] By adopting the above technical solution, the mounting grooves on the first main mounting plate and the second main mounting plate, and the subsequent design of the auxiliary mounting plate covering part of the mounting grooves can ensure that the grouting sleeve is in the correct position during the test. This design helps to reduce test errors and improve the accuracy of test results. By fixing the two ends of the grouting sleeve by the first fixed anchor group and the second fixed anchor group, respectively, it can ensure that the grouting sleeve will not move or deform during the test, thereby ensuring the reliability of the test results. Furthermore, the test process can be applied to different types of grouting sleeves and steel bars, and only the position and size of the mounting plate and the fixed anchor group need to be adjusted. And through the close cooperation between the fixed anchor group and the mounting plate, it can be ensured that the grouting sleeve will not fall off or fly out during the test, which helps to ensure the safety of the testers.

[0054] As one of the basic industries of my country's national economy, the construction industry has always shown a trend of vigorous development. In recent years, with the increasing advancement of my country's industrialization process, prefabricated buildings have been vigorously developed. They are characterized by energy saving and environmental protection, simple and efficient construction, and low labor demand. They are the main direction of modern construction development. An important connecting component in prefabricated buildings is the grouting sleeve connector. Although the grouting sleeve connection technology has been widely used, there is still a lack of equipment for cyclic tension and compression tests on grouting sleeves in the prior art. The common tension and compression test method of grouting sleeves is to weld the steel bars at both ends of the grouting sleeve to the steel plate or steel column to ensure the strength during the test. After the test is completed, the steel bars need to be cut and disassembled during the disassembly process, which has the problems of low test efficiency and safety hazards.

[0055] In order to solve the above technical problems, the present invention discloses a tensile and compressive test device for a grouting sleeve, by arranging a first mounting mechanism 200 and a second mounting mechanism 300 on the test device at intervals to respectively fix and mount the two ends of the grouting sleeve 400 for tensile and compressive tests, and the first mounting mechanism 200 and the second mounting mechanism 300 are arranged as a recyclable and disassembled structure, which has the advantages of ingenious structure, convenient and quick disassembly and assembly, and testing.

And one of the first mounting mechanism 200 and the second mounting mechanism 300 is arranged on the power output end 510 of the hydraulic drive component 500. When performing the tension and compression test, when the power output end 510 of the hydraulic drive component 500 controls the first mounting mechanism 200 to move in a direction close to the second mounting mechanism 300, the grouting sleeve 400 performs a compression test, and when the power output end 510 of the hydraulic drive component 500 controls the first mounting mechanism 200 to move in a direction away from the second mounting mechanism 300, the grouting sleeve 400 performs a tensile test.

[0057] It should be further explained that the tension and compression test device disclosed in the present invention can be placed horizontally or vertically.

The hydraulic drive component 500 is fixedly arranged below the crossbeam 130, and its power output end 510 faces one side of the base 110, and the power output end 510 is also fixedly arranged with a first support seat 140, and a plurality of first fixing screws 141 are arranged on the first support seat 140 near the outer periphery. The first mounting mechanism 200 includes a first main mounting plate 210 and a first fixing anchor group 220. The first main mounting plate 210 is fixedly connected to the power output end 510, see Figure 2 The first main mounting plate 210 is provided with a first mounting groove 211 and a plurality of screw mounting grooves 212. The plurality of screw mounting grooves 212 on the first main mounting plate 210 are respectively matched with the plurality of first fixing screws 141 one by one and fixedly connected by fasteners 142. The first adjustment portion 240 of the first mounting mechanism 200 is provided at an end of the first support seat 140 away from the hydraulic drive component 500. The first mounting groove 211 extends inward from a side edge of the first main mounting plate 210 and penetrates a portion of the first main mounting plate 210. One end of the grouting sleeve 400 to be tested extends into the first mounting groove 211 and is moved and installed along the first mounting groove 211. For further information, see Figure 1 and Figure 4 The first fixing anchor group 220 is arranged at one end of the grouting sleeve 400 extending out of the first main mounting plate 210 to fix one end of the grouting sleeve 400 on the first main mounting plate 210 .

[0060] A plurality of second support columns 111 are also provided in the middle part of the base 110, a second support seat 113 is provided on the second support column 111, the second support seat 113 is fixedly connected to the second support column 111, a second mounting mechanism 300 is fixedly provided on the second support seat 113, the second mounting mechanism 300 includes a second main mounting plate 310 and a second fixing anchor group 320, a plurality of second fixing screws 112 are arranged at intervals on the second support column 111, a plurality of screw mounting grooves 212 on the second main mounting plate 310 are respectively matched with the plurality of second fixing screws 112 one by one, and are fixedly connected by fasteners 142, and the second mounting mechanism 300 also includes a second adjustment portion 340 provided at an end of the second support seat 113 away from the base 110.

[0061] For example, in a preferred implementation method disclosed in this embodiment, four support columns 120 are arranged on the base 110, the cross beam 130 is arranged on the top of the four support columns 120, the hydraulic drive component 500 is fixedly arranged below the cross beam 130, the power output end 510 faces the side of the base 110, the power output end 510 is fixedly arranged on the first support seat 140, four first fixing screws 141 are arranged on the first support seat 140, the first main mounting plate 210 is fastened by the four first fixing screws 141 and the fastening bolts, the first main mounting plate 210 has four screw mounting grooves 212 adapted to the four first fixing screws 141, and the second main mounting plate 310 is similarly fixedly arranged on the second support seat 113 of the base 110. With such a structure, after the two ends of the grouting sleeve 400 are respectively fixed to the two ends of the first mounting mechanism 200 and the second mounting mechanism 300, when the power output end 510 of the hydraulic drive component 500 moves upward, it will drive the first support seat 140 and the first mounting mechanism 200 to move upward, and apply tension to the upper end of the grouting sleeve 400 for a tensile test; when the power output end 510 of the hydraulic drive component 500 moves downward, it will drive the first support seat 140 and the first mounting mechanism 200 to move downward, and apply pressure to the upper end of the grouting sleeve 400 for a compression test.

[0062] The second main mounting plate 310 is provided with a second mounting groove 311, which extends inward from one side edge of the second main mounting plate 310 and penetrates a portion of the second main mounting plate 310. The other end of the grouting sleeve 400 extends into the second mounting groove 311 and moves along the second mounting groove 311 for installation. Figure 1 The second fixing anchor group 320 is arranged at the other end of the grouting sleeve 400 extending out of the second main mounting plate 310 to fix the other end of the grouting sleeve 400 on the second main mounting plate 310.

[0063] That is to say, in the scheme disclosed in the present embodiment, a first installation groove 211 is provided on the first main installation plate 210 for the end of the grouting sleeve 400 to be installed in translation. After the end of the grouting sleeve 400 is installed in the first installation groove 211, it is detachably fixedly connected by the first fixing anchor group 220. A second installation groove 311 is provided on the second main installation plate 310 for the end of the grouting sleeve 400 to be installed in translation. After the other end of the grouting sleeve 400 is installed in the second installation groove 311, it is detachably fixedly connected by the second fixing anchor group 320. Therefore, the first fixing anchor group 220 and the second fixing anchor group 320 can be common steel bar anchor heads or mechanical anchor groups, for example, a fixing anchor group composed of a pad and a nut, a fixing anchor group composed of a steel plate and fasteners such as bolts, or a fixing anchor group composed of a steel plate and a clamp. Furthermore, the first main mounting plate 210 and the second main mounting plate 310 may be carbon steel plates, alloy steel plates, hot-rolled steel plates, etc. Those skilled in the art may design and select them according to actual needs, and this embodiment does not specifically limit this.

[0064] Further preferably, see Figure 1 In the tensile and compressive test device of the grouting sleeve disclosed in this embodiment, the first mounting mechanism 200 and the second mounting mechanism 300 are arranged at intervals from each other in the vertical direction, and the spacing dimension of the first mounting mechanism 200 and the second mounting mechanism 300 is smaller than the length dimension of the grouting sleeve 400, and the grouting sleeve 400 is fixed between the first mounting mechanism 200 and the second mounting mechanism 300 in the vertical direction. When viewed in the vertical direction, the first mounting groove 211 and the second mounting groove 311 are both opened to the same side, and the inner peripheral contours of the first mounting groove 211 and the second mounting groove 311 overlap each other in the vertical direction, and the bottom end of the inner peripheral contour is located at the geometric center of the corresponding main mounting plate. It should be noted that the first mounting groove 211 and the second mounting groove 311 are opened to the same side, so that when installing and removing the grouting sleeve 400, the two ends of the grouting sleeve 400 are aligned with the first mounting groove 211 and the second mounting groove 311, and then the grouting sleeve 400 is moved for installation or removal, which has the advantages of simple, quick and convenient disassembly.

[0065] During the test of the tension and compression test device for the grouting sleeve disclosed in the present invention, both ends of the grouting sleeve 400 to be tested can be detachably and quickly and conveniently installed on the first installation mechanism 200 and the second installation mechanism 300. The installation and disassembly process of the grouting sleeve 400 is simplified, so that during the test preparation process, the installation and adjustment of the grouting sleeve 400 are faster, and the test preparation time is shortened. The device can accurately evaluate the performance of the grouting sleeve 400 under tension and pressure, providing reliable data support for engineering applications.

[0066] See also Figure 1 It should be further explained that, since the grouting sleeve 400 is arranged in the vertical direction, the first mounting mechanism 200 and the second mounting mechanism 300 are symmetrical and arranged in opposite directions in the vertical direction, so as to fix the two ends of the grouting sleeve 400, that is, the first mounting mechanism 200 and the second mounting mechanism 300 are arranged with the same structure and opposite directions.

[0067] See next Figure 1 as well as Figure 2 The first mounting mechanism 200 is composed of a first main mounting plate 210 and a first auxiliary mounting plate 230. The first auxiliary mounting plate 230 is arranged on the side of the first main mounting plate 210 where the first fixing anchor group 220 is arranged. The outer peripheral contour size of the first auxiliary mounting plate 230 is smaller than that of the first main mounting plate 210 and at least covers a portion of the first mounting groove 211. In this embodiment, the first main mounting plate 210 and the first auxiliary mounting plate 230 are both rectangular plates. The first auxiliary mounting plate 230 can be set to be one-half, one-third or one-quarter the size of the first main mounting plate 210, and screw mounting grooves 212 are arranged at the four corners of the first main mounting plate 210. The screw mounting grooves 212 are used to fix the first main mounting plate 210. Please refer to Figure 2 The first auxiliary mounting plate 230 extends inward from one side edge of the first main mounting plate 210 to cover a portion of the area where the first mounting groove 211 is located. The length dimension of the first auxiliary mounting plate 230 is equal to or less than the width dimension of the first main mounting plate 210, and the width dimension of the first auxiliary mounting plate 230 is less than the length dimension of the first mounting groove 211. The edge of the first auxiliary mounting plate 230 corresponding to one side edge of the first main mounting plate 210 is provided with an installation avoidance groove 231 corresponding to the screw mounting groove 212.

[0068] For example, in a preferred implementation provided in this embodiment, the first main mounting plate 210 is a square steel plate, and the area of ​​the first main mounting plate 210 is larger than the area of ​​the first auxiliary mounting plate 230. A first mounting groove 211 is provided on one side of the first main mounting plate 210, and the first mounting groove 211 runs through half of the first main mounting plate 210. Figure 2 and Figure 5 The first auxiliary mounting plate 230 is located on the upper side of the first main mounting plate 210 and covers part of the first mounting groove 211. For example, when the size of the first main mounting plate 210 is set to 20cm*20cm, the length of the first mounting groove 211 can be set to 10cm, the width of the first mounting groove 211 is adapted to the outer diameter of the fixed end of the grouting sleeve 400 to be tested, the size of the first auxiliary mounting plate 230 can be set to 20cm*8cm, or the width of the first auxiliary mounting plate 230 can be within 4 to 8cm. Those skilled in the art can design and select according to actual needs, and this embodiment does not specifically limit this.

[0069] Likewise, see Figure 1 and Figure 3 , the setting structure of the second mounting mechanism 300 is the same as that of the first mounting mechanism 200. The second mounting mechanism 300 is composed of a second main mounting plate 310 and a second sub-mounting plate 330. The second sub-mounting plate 330 is arranged on the side of the second main mounting plate 310 where the second fixing anchor group 320 is arranged. The outer peripheral contour size of the second sub-mounting plate 330 is smaller than that of the second main mounting plate 310, and at least covers a part of the second mounting groove 311. Similarly, the second main mounting plate 310 and the second sub-mounting plate 330 are both rectangular plates. The four corners of the second main mounting plate 310 are provided with screw mounting grooves 212. The second sub-mounting plate 330 extends inward from one side edge of the second main mounting plate 310 to cover a part of the area where the second mounting groove 311 is located. Among them, the length dimension of the second sub-mounting plate 330 is equal to or less than the width dimension of the second main mounting plate 310, and the width dimension of the second sub-mounting plate 330 is less than the length dimension of the second mounting groove 311. The second auxiliary mounting plate 330 is provided with an installation avoidance groove 231 corresponding to the screw mounting groove 212 at an edge corresponding to one side edge of the second main mounting plate 310. Similarly, in this embodiment, the second main mounting plate 310 is a square steel plate, the second auxiliary mounting plate 330 is a rectangular steel plate, and the area of ​​the second auxiliary mounting plate 330 is smaller than that of the second main mounting plate 310.

[0070] For example, when the size of the second main mounting plate 310 is set to 20cm*20cm, the length of the second mounting groove 311 can be set to 10cm, the width of the second mounting groove 311 is adapted to the outer diameter of the fixed end of the grouting sleeve 400 to be tested, the size of the second auxiliary mounting plate 330 can be set to 20cm*8cm, or the width of the second auxiliary mounting plate 330 can be within 4 to 8cm. Those skilled in the art can design and select according to actual needs, and this embodiment does not make specific limitations on this.

[0071] With this structural design, the first main mounting plate 210 and the first auxiliary mounting plate 230, the second main mounting plate 310 and the second auxiliary mounting plate 330 can be flexibly assembled, and the effective force-bearing thickness of the mounting plates can be significantly increased by overlapping the two mounting plates, thereby improving the bending resistance of the first main mounting plate 210 and the second main mounting plate 310, and effectively reducing the deformation degree of the first main mounting plate 210 and the second main mounting plate 310 after the grouting sleeve 400 is tensile loaded, thereby extending the service life of the first main mounting plate 210 and the second main mounting plate 310, and enabling the loading test to be carried out more effectively.

[0072] An implementation of this embodiment also discloses a tension and compression test device for a grouting sleeve, see Figure 1 and Figure 4The first fixed anchor group 220 includes a first anchor gasket 221, a first clamping portion 222 and a first anchor body 223. The first anchor gasket 221 is arranged on the side of the first main mounting plate 210 where the end of the grouting sleeve 400 extends out. The first clamping portion 222 is arranged on the side of the first anchor gasket 221 away from the first main mounting plate 210. The first anchor body 223 is at least partially arranged in the clamping space of the first clamping portion 222. The first anchor gasket 221, the first clamping portion 222 and the first anchor body 223 are sequentially detachably sleeved on one end of the grouting sleeve 400. The middle parts of the first anchor gasket 221, the first anchor body 223 and the first clamping portion 222 all have a first through hole 224 for the end of the grouting sleeve 400 to penetrate and connect.

[0073] In the present embodiment, the first anchor gasket 221 can be set as a steel gasket, or can be set as a flexible gasket, such as a rubber gasket, etc. The first anchor body 223 and the first clamping part 222 are set as mutually clampable or detachable structures. For example, a clamping groove can be set on the corresponding outer wall of the first anchor body 223, and a clamping groove can be set on the inner wall of the first clamping part 222. The clamping groove and the clamping groove cooperate with each other to fix the first anchor body 223 and the first clamping part 222 together, and to fix the end of the grouting sleeve 400 located in the middle of the first anchor body 223. Alternatively, in another implementation, the first anchor body 223 is set as a plurality of components, for example, the first anchor body 223 is set as 2, 3, 4 or even more separate components. Those skilled in the art can design and select according to actual needs. For example, in Figure 5 In a disclosed structure, the first anchor body 223 in this embodiment is configured to be composed of three separate components, and the outer wall of each separate component and the inner wall of the first clamping portion 222 are provided with a threaded clamping groove. When fixing the end of the grouting sleeve 400, the three separate components of the first anchor body 223 are first placed in the first clamping portion 222, and the threaded clamping grooves are aligned, and then the first anchor body 223 is rotated and tightened. After the first clamping portion 222 and the first anchor body 223 are rotated and clamped to each other stably, the end of the grouting sleeve 400 is also fixed and installed. For more details, please refer to Figure 4 The first clamping part 222 is configured to be a truncated cone with a concave portion on one side, and the axial cross-section of the first anchor body 223 is a trapezoidal profile. The concave portions of the first anchor body 223 and the first clamping part 222 respectively form clamping spaces that match the shapes of the first clamping part 222 and the first anchor body 223. Through this structure, when the first anchor body 223 and the first clamping part 222 are clamped and fixed, the end of the grouting sleeve 400 is stably clamped.

[0074] Similarly, the structure of the second fixed anchor group 320 is the same as that of the first fixed anchor group 220, and the only difference is that the setting direction is opposite. The second fixed anchor group 320 includes a second anchor gasket (not shown in the figure), a second clamping part (not shown in the figure) and a second anchor body (not shown in the figure). The second anchor gasket is fitted on the side of the other end of the second main mounting plate 310 from which the grouting sleeve 400 extends, the second clamping part is arranged on the side of the first anchor gasket 221 away from the second main mounting plate 310, the second anchor body is at least partially arranged in the clamping space of the second clamping part, and the second anchor gasket, the second clamping part, and the second anchor body are sequentially detachably sleeved on the other end of the grouting sleeve 400. The middle parts of the second anchor gasket, the second anchor body and the second clamping part all have a second through hole for the end of the grouting sleeve 400 to pass through and connect. The second clamping portion is also configured to be a truncated cone with a recessed portion on one side, and the axial cross-section of the second anchor body is a trapezoidal profile, and the recessed portion of the second clamping portion forms a clamping space that matches the shape of the second anchor body.

[0075] The embodiment of the present invention also discloses a tensile and compressive test device for a grouting sleeve, see Figure 1 and Figure 4 The first mounting mechanism 200 further includes a first adjusting portion 240 detachably disposed at one end of the grouting sleeve 400, the first adjusting portion 240 includes a first adjusting screw 241 and two first rotating threaded pressing plates 242 adjustably sleeved on the first adjusting screw 241, the two first rotating threaded pressing plates 242 are arranged at intervals, the outer wall of the first adjusting screw 241 is provided with an outer thread, the inner wall of each first rotating threaded pressing plate 242 is provided with an inner thread adapted to the outer thread, and the end of a first rotating threaded pressing plate 242 close to the grouting sleeve 400 can be plugged into one end of the grouting sleeve 400. For example, the upper end of the grouting sleeve 400 is plugged and fixed to the end of a first rotating threaded pressing plate 242 close to the grouting sleeve 400, and then rotating the other first rotating threaded pressing plate 242 can make the other first rotating threaded pressing plate 242 move up and down along the height direction of the first adjusting screw 241. And before conducting the compression test, a first rotating threaded pressure plate 242 away from one end of the grouting sleeve 400 is rotated to move it upward and the top end is abutted against the bottom of the first support seat 140 of the power output end 510 of the hydraulic drive component 500. Through such a structure, when conducting a compression test, the compression force of the hydraulic drive component 500 can be directly transmitted to the upper end of the grouting sleeve 400 through the first rotating threaded pressure plate 242 and the first adjusting screw 241, and then pressure is directly applied to the upper end of the grouting sleeve 400 to perform a compression test.

[0076] The second mounting mechanism 300 also includes a second adjusting portion 340 detachably arranged on the other end portion of the grouting sleeve 400, the second adjusting portion 340 includes a second adjusting screw 341 and two second rotating threaded pressure plates 342 adjustably sleeved on the second adjusting screw 341, the two second rotating threaded pressure plates 342 are arranged at intervals, the outer wall portion of the second adjusting screw 341 is provided with an external thread, the inner wall portion of each second rotating threaded pressure plate 342 is provided with an internal thread adapted to the external thread, and a second rotating threaded pressure plate 342 close to the grouting sleeve 400 is plugged and fixed to the other end portion of the grouting sleeve 400.

[0077] With this structural design, the first adjustment portion 240 is provided to extend the distance between the top of the first fixed anchor group 220 and the hydraulic drive component 500. When conducting a compressive strength test on the grouting sleeve 400 connector, the two first rotating threaded pressure plates 242 are rotated so that the top of one of the first rotating threaded pressure plates 242 is in close contact with the bottom of the power output end 510 of the hydraulic drive component 500. The compression torque of the hydraulic drive component 500 is directly transmitted to the grouting sleeve 400, thereby achieving effective pressurization of the grouting sleeve 400.

[0078] Next, the state and process of the tensile and compressive test device for the grouting sleeve disclosed in the present invention when the grouting sleeve 400 is clamped and then subjected to the tensile test and the compressive test are briefly described:

[0079] During the installation stage of the grouting sleeve 400, it is necessary to separate the first main mounting plate 210 and the first auxiliary mounting plate 230, separate the second main mounting plate 310 and the second auxiliary mounting plate 330, and use the crossbeam 130 to lift the hydraulic drive component 500 upward so that there is enough space between the first mounting mechanism 200 and the second mounting mechanism 300 to place the grouting sleeve 400, and then place the grouting sleeve 400 vertically, and align the two ends of the grouting sleeve 400 with the first mounting groove 211 of the first main mounting plate 210 and the second mounting groove 311 of the second main mounting plate 310 respectively, and then move, and then fix the end of the grouting sleeve 400 extending out of the first main mounting plate 210 by the first fixing anchor group 220; fix the end of the grouting sleeve 400 extending out of the second main mounting plate 310 by the second fixing anchor group 320, and fix the first auxiliary mounting plate 230 and the second auxiliary mounting plate 330 to one side of the first main mounting plate 210 and the second main mounting plate 310 respectively. When the grouting sleeve 400 is subjected to a tensile test, the power output end 510 of the hydraulic drive component 500 drives the first main mounting plate 210 and the upper end of the grouting sleeve 400 to move upward for the tensile test. During the test, the tensile torque, time and length can be adjusted for separate tests.

[0080] Before performing a compression test on the grouting sleeve 400, it is necessary to rotate the two first rotating threaded pressure plates 242 so that the top of one of the first rotating threaded pressure plates 242 is in close contact with the first support seat 140 at the bottom of the power output end 510 of the hydraulic drive component 500, and the bottom of the other first rotating threaded pressure plate 242 is plugged and fixed to the upper end of the grouting sleeve 400. In this way, when performing a compression test, the pressure output by the power output end 510 of the hydraulic drive component 500 can be directly transmitted to the first rotating threaded pressure plate 242 through the first support seat 140, and finally directly act on the upper end of the grouting sleeve 400 to perform a compression test on the grouting sleeve 400.

[0081] The present invention also discloses a test method for a tensile and compressive test device for a grouting sleeve applied to any one of the above items, see Figure 6 , the method comprising:

[0082] S1. Move the two ends of the grouting sleeve 400 to be tested from the first mounting groove 211 of the first main mounting plate 210 and the second mounting groove 311 of the second main mounting plate 310 respectively, and make the two ends of the grouting sleeve 400 located in the middle of the first main mounting plate 210 and the second main mounting plate 310.

[0083] It should be noted that, before step S1, during the installation stage of the grouting sleeve 400, it is necessary to separate the first main mounting plate 210 and the first auxiliary mounting plate 230, separate the second main mounting plate 310 and the second auxiliary mounting plate 330, and use the crossbeam 130 to lift the hydraulic drive component 500 upward so that there is enough space between the first mounting mechanism 200 and the second mounting mechanism 300 to place the grouting sleeve 400, and then place the grouting sleeve 400 vertically, and align the two ends of the grouting sleeve 400 with the first mounting groove 211 of the first main mounting plate 210 and the second mounting groove 311 of the second main mounting plate 310 for movement. In step S1, the steps of installing the grouting sleeve 400 and removing the grouting sleeve 400 are exactly the same, both of which allow the two ends of the grouting sleeve 400 to move along the first installation groove 211 and the second installation groove 311, which is simple and convenient to install and remove, and finally the two ends of the grouting sleeve 400 are respectively located at the geometric center positions of the first main installation plate 210 and the second main installation plate 310, as shown in FIG. Figure 5 As shown, the upper end of the grouting sleeve 400 is located at the geometric center of the first main mounting plate 210 .

[0084] S2. Fix one end of the grouting sleeve 400 extending out of the first main mounting plate 210 through the first fixing anchor group 220 ; fix one end of the grouting sleeve 400 extending out of the second main mounting plate 310 through the second fixing anchor group 320 .

[0085] In the above step S2, when fixing the end (upper end) of the grouting sleeve 400 extending out of the first main mounting plate 210 by the first fixing anchor group 220, firstly place the first anchor gasket 221 on the side of the first main mounting plate 210 away from the grouting sleeve 400, then sleeve the first clamping part 222 on the upper end of the grouting sleeve 400, and then install the first anchor body 223 on the first clamping part 222 to achieve the installation and fixation of the upper end of the grouting sleeve 400. Then, fix the end (lower end) of the grouting sleeve 400 extending out of the second main mounting plate 310 by the second fixing anchor group 320, firstly place the second anchor gasket on the side of the second main mounting plate 310 away from the grouting sleeve 400, then sleeve the second clamping part on the lower end of the grouting sleeve 400, and then install the second anchor body on the second clamping part to achieve the installation and fixation of the lower end of the grouting sleeve 400.

[0086] S3. Fix the first auxiliary mounting plate 230 and the second auxiliary mounting plate 330 to one side of the first main mounting plate 210 and the second main mounting plate 310 respectively, and the first auxiliary mounting plate 230 and the second auxiliary mounting plate 330 cover a part of the first mounting groove 211 and a part of the second mounting groove 311 respectively.

[0087] In the above step S3, after the first auxiliary mounting plate 230 is fixed to one side of the first main mounting plate 210 and the second auxiliary mounting plate 330 is fixed to one side of the second main mounting plate 310, not only a portion of the first mounting groove 211 and a portion of the second mounting groove 311 are covered, but also the effective force-bearing thickness of the mounting plate is increased, the bending resistance of the first main mounting plate 210 and the second main mounting plate 310 is improved, the service life of the first main mounting plate 210 and the second main mounting plate 310 is extended, and the loading test can be carried out more effectively.

[0088] S4. The power output end 510 of the hydraulic drive component 500 drives the first installation mechanism 200 and one end of the steel bar of the grouting sleeve 400 to move back and forth and perform a tensile test or a compression test.

[0089] It should be noted that in step S4, the power output end 510 of the hydraulic drive component 500 drives the upper end of the grouting sleeve 400 for testing. Those skilled in the art can also set the hydraulic drive component 500 at the lower end for testing, and directly perform stretching when performing a tensile test. When performing a compression test, it is necessary to rotate the two first rotating threaded pressure plates 242 before compression, so that the top of one of the first rotating threaded pressure plates 242 is in close contact with the first support seat 140 at the bottom of the power output end 510 of the hydraulic drive component 500, and the bottom of the other first rotating threaded pressure plate 242 is plugged and fixed to the upper end of the grouting sleeve 400. In this way, when performing a compression test, the pressure output by the power output end 510 of the hydraulic drive component 500 can be directly transmitted to the first rotating threaded pressure plate 242 through the first support seat 140, and finally directly acts on the upper end of the grouting sleeve 400, so as to perform an effective compression test on the grouting sleeve 400.

[0090] By adopting the above method, through the mounting grooves on the first main mounting plate 210 and the second main mounting plate 310, and the subsequent design of the auxiliary mounting plate covering part of the mounting grooves, it can be ensured that the grouting sleeve 400 is in the correct position during the test. This design helps to reduce test errors and improve the accuracy of test results. By fixing the two ends of the grouting sleeve 400 by the first fixed anchor group 220 and the second fixed anchor group 320 respectively, it can be ensured that the grouting sleeve 400 will not move or deform during the test, thereby ensuring the reliability of the test results. Furthermore, the test process can be applied to different types of grouting sleeves 400 and steel bars, and only the position and size of the mounting plate and the fixed anchor group need to be adjusted. And through the close cooperation of the fixed anchor group and the mounting plate, it can be ensured that the grouting sleeve 400 will not fall off or fly out during the test, which helps to ensure the safety of the testers.
