Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of concrete strength detection, and particularly to a concrete strength detection device for building construction. Background Technique
[0002] As one of the core materials of modern buildings, concrete plays an irreplaceable role in building construction. Concrete is widely used in various key parts of building construction. Its strength grade is closely related to its use. The quality of concrete directly affects the results of construction projects. Therefore, the detection of concrete is essential. And the compressive strength is one of the most important indicators for detecting the quality of concrete, which has an important impact on the durability and safety of concrete structures.
[0003] During the existing concrete strength detection process, generally, the concrete specimen is positioned through a positioning structure, and then a stable downward pressure is applied on its top using a hydraulic cylinder to achieve the strength detection. However, during the detection process, the concrete may be broken into fragments under the action of the downward pressure. The broken fragments may fly onto the body of the detection personnel under the action of the pressure, causing scratches or impacts on the body of the detection personnel, reducing the safety of the detection. Moreover, the flying fragments will also scatter in the surrounding environment. Due to the small volume of the fragments, the scattered fragments greatly increase the cleaning difficulty and reduce the efficiency of concrete detection.
[0004] Therefore, it is necessary to provide a concrete strength detection device for building construction, aiming to solve the above problems. Summary of the Invention

An active connection assembly is provided between the protective frame and the lifting plate.
[0007] As a further solution of the present invention, the positioning component includes four guiding frames circumferentially distributed on the inner wall of the protection frame and four groups of movable modules circumferentially distributed on the support frame. The movable modules correspond to the guiding frames one by one. Each movable module includes two sliding grooves. A cross bar is arranged in the sliding groove, and a sliding seat slidably matched with the cross bar is slidably arranged in the sliding groove. A first spring sleeved outside the cross bar is connected between the sliding groove and the sliding seat. A vertical plate is installed on the sliding seat. A connecting plate is connected between the two vertical plates. An abutting roller is movably arranged on one side of the connecting plate away from the middle of the support frame. A sliding rod is slidably arranged on the vertical plate. One end of the sliding rod close to the middle of the support frame is connected with an abutting plate. A second spring sleeved outside the sliding rod is connected between the abutting plate and the vertical plate.
[0008] As a further solution of the present invention, the movable connection component includes a plurality of limiting holes arranged on the column. Two ends of the top of the protection frame are symmetrically installed with guiding cylinders. Guiding grooves are symmetrically arranged at both ends of the guiding cylinder. Limiting rods are symmetrically and slidably arranged in the guiding cylinder. A third spring arranged inside the guiding cylinder is connected between the two ends of the two limiting rods close to each other. The outer end of the limiting rod is movably matched with the limiting hole. One ends of the two limiting rods located inside the guiding cylinder and close to each other are respectively connected with movable rods slidably matched with the guiding grooves. J-shaped guiding plates movably matched with the movable rods are symmetrically installed on the lifting plate. The J-shaped guiding plate and the lifting plate are connected through a mounting frame.
[0009] As a further solution of the present invention, an observation window is arranged on the front surface of the protection frame.
[0010] As a further solution of the present invention, a plurality of chip collecting grooves are arranged at the center of the bracket component. A cavity is arranged inside the support frame. A plurality of cross plates are horizontally distributed inside the cavity. A drawer is slidably arranged on the cross plate.
[0011] As a further solution of the present invention, the guiding frame is a right trapezoidal frame with an inclined surface facing the middle of the support frame.
[0012] As a further solution of the present invention, the J-shaped guiding plate is composed of an inclined plate and a semi-circular ring.
[0013] As a further solution of the present invention, the length of the guiding groove is the same as the projection length of the J-shaped guiding plate on the horizontal plane.
[0014] As a further solution of the present invention, a plurality of limiting holes are on the same horizontal plane, and the axis of the limiting hole is parallel to the axis of the limiting rod.
[0015] In summary, the embodiments of the present invention have the following beneficial effects compared with the prior art: 1. In the present invention, the guiding frame drives the vertical plate to approach the center of the supporting frame by means of the inclined plane being in movable abutment with the abutting roller and the sliding seat being in sliding fit with the sliding groove. The vertical plate drives the abutting plate to approach the middle part of the supporting frame by being connected to the sliding rod and the second spring, so that the abutting plate closely adheres to the outer wall of the concrete specimen. When the bottom of the protection frame is in fit with the abutting ring groove, the guiding frame stops moving downward. At this time, the positions of the sliding seat and the vertical plate are fixed, and the four walls of the concrete specimen can be positioned. At the same time, by being circumferentially distributed on the abutting plate, the non-centered concrete specimen can be pushed to the center of the supporting frame during the positioning process of the concrete specimen, realizing the automatic centering positioning of the concrete specimen, which is convenient for subsequent strength testing. 2. In the present invention, when the movable rod is in a clamped state with the J-shaped guiding plate, the synchronous lifting and lowering of the protection frame and the lifting plate can be realized. The hydraulic cylinder pushes the lifting plate to move downward by means of the sliding fit between the lifting plate and the column. When the limiting rod corresponds to the limiting hole, the third spring elongates and pushes the limiting rod to move outward, realizing the connection between the limiting rods, so that the protection frame is in a positioned state, and the synchronous movement between the protection frame and the lifting plate is released. After the strength test of the concrete specimen is completed, the lifting plate drives the J-shaped guiding plate to move upward synchronously by being connected to the mounting frame, and the movable rod is re-clamped with the semi-circular ring on the J-shaped guiding plate, realizing the re-synchronous movement of the protection frame and the lifting plate, and the protection frame can be synchronously lifted upward, which is convenient for taking out the tested concrete specimen and cleaning the surface of the supporting frame. 3. In the present invention, during the process of the protection frame moving downward to be positioned, the automatic centering positioning of the concrete specimen can be realized, that is, when performing the strength test on the concrete specimen, the tester only needs to first place the concrete specimen to be tested on the supporting frame, and then control the hydraulic cylinder to push the lifting plate to move downward, then the automatic centering positioning and strength test of the concrete specimen can be realized. There is no need for the tester to perform too many steps, which greatly simplifies the testing steps, and can well avoid the problem that the test result is inaccurate due to inaccurate operation steps, improving the testing efficiency and accuracy of the concrete specimen. 4. In the present invention, through a plurality of chip collecting grooves, it is convenient to guide the waste chips and dust generated during the strength test of the concrete specimen into the drawer, which helps the centralized treatment of waste chips and dust. Through the observation window, it is convenient for the tester to observe the progress of the strength test of the concrete specimen in real time, realizing the effective isolation between the concrete specimen and the tester, and improving the safety of the tester.

Detailed implementation manners
[0024] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0025] The following describes the specific implementation of the present invention in detail with specific embodiments.
[0026] In one embodiment of the present invention, refer to Figures 1 - 3, a concrete strength detection device for building construction, including a support assembly 1. The support assembly 1 includes a support frame 101. A top plate 105 is provided on the support frame 101. Four corners of the support frame 101 are connected to the top plate 105 through columns 104. An abutting ring groove 102 is provided on the support frame 101. A protective frame 3 that is slidably arranged on the column 104 and abuts against the abutting ring groove 102 is provided on the column 104. A positioning assembly 2 for fixing the concrete specimen 7 is provided between the support frame 101 and the protective frame 3. A lifting plate 4 located inside the protective frame 3 is slidably arranged on the column 104. A pressure sensor 401 is provided on one side of the lifting plate 4 close to the support frame 101. A hydraulic cylinder 5 connected to the top plate 105 is arranged on the other side of the lifting plate 4. An active connection assembly 6 is provided between the protective frame 3 and the lifting plate 4.
[0027] In this embodiment, through the positioning assembly 2, the four side walls of the concrete specimen 7 can be abutted to achieve automatic centering and positioning of the concrete specimen 7, avoiding the phenomenon of deviation of the concrete specimen 7 during strength detection, which helps to improve the detection accuracy. Through the cooperation of the protective frame 3 and the abutting ring groove 102, the concrete specimen 7 can be isolated from the external environment, avoiding the problem that the concrete specimen 7 is crushed and ejected during strength detection, resulting in scratches on the testers, improving the safety of the device. At the same time, it is convenient to collect the fragments and dust after the concrete specimen 7 is crushed, avoiding the problem of fragments and dust entering the surrounding environment and causing pollution. Through the cooperation of the lifting plate 4, the pressure sensor 401 and the hydraulic cylinder 5, the concrete specimen 7 can be stably pressurized, facilitating the effective detection of the strength performance of the concrete specimen 7. Through the active connection assembly 6, the orderly downward movement of the protective frame 3 and the lifting plate 4 can be realized, ensuring that the concrete specimen 7 is in a sealed environment before the strength detection of the concrete specimen 7, avoiding the problem that the protective frame 3 and the abutting ring groove 102 may not be effectively matched during the strength detection of the concrete specimen 7, improving the safety of the detection, and having the effects of automatic centering and positioning, safety protection, flexible linkage, stable pressurization, effective detection, reliable structure and convenient operation; Among them, several chip collection grooves 103 are provided at the center of the support assembly 1. A cavity 106 is provided inside the support frame 101. Several horizontal plates 107 are horizontally distributed inside the cavity 106. A drawer 108 is slidably arranged on the horizontal plate 107. Through the several chip collection grooves 103, it is convenient to introduce the waste chips and dust generated during the strength detection of the concrete specimen 7 into the drawer 108, which helps to centrally process the waste chips and dust. An observation window 301 is provided on the front of the protective frame 3. Through the observation window 301, it is convenient for the tester to observe the progress of the strength detection of the concrete specimen 7 in real time, realizing the effective isolation between the concrete specimen 7 and the tester, and improving the safety of the tester.
[0028] In one embodiment of the present invention, refer to Figures 1 - 4 , the positioning assembly 2 includes four guiding frames 211 circumferentially distributed on the inner wall of the protective frame 3 and four groups of movable modules circumferentially distributed on the support frame 101. The movable modules correspond to the guiding frames 211 one by one. Each movable module includes two sliding grooves 201. A cross bar 202 is arranged in the sliding groove 201. A sliding seat 204 slidably matched with the cross bar 202 is slidably arranged in the sliding groove 201. A first spring 203 sleeved outside the cross bar 202 is connected between the sliding groove 201 and the sliding seat 204. A vertical plate 205 is installed on the sliding seat 204. A connecting plate 206 is connected between the two vertical plates 205. An abutting roller 207 is movably arranged on one side of the connecting plate 206 away from the middle of the support frame 101. A sliding rod 208 is slidably arranged on the vertical plate 205. An abutting plate 209 is connected to one end of the sliding rod 208 close to the middle of the support frame 101. A second spring 210 sleeved outside the sliding rod 208 is connected between the abutting plate 209 and the vertical plate 205.
[0029] In this embodiment, in the initial state, the protective frame 3 is at the highest point, and the first spring 203 and the second spring 210 are in their original lengths. At this time, the connecting plate 206 is away from the center of the support frame 101, the abutting plate 209 is close to the center of the support frame 101, and the guiding frame 211 is at the highest point; When it is necessary to position the concrete specimen 7 placed on the support frame 101, the hydraulic cylinder 5 pushes the lifting plate 4 downward. The lifting plate 4 drives the protective frame 3 to slide downward along the column 104 by being connected to the movable connection assembly 6. After the bottom of the inclined surface of the guiding frame 211 contacts the outer wall of the abutting roller 207, the protective frame 3 continues to move downward. The protective frame 3 drives the guiding frame 211 to continue to move downward. The guiding frame 211 drives the vertical plate 205 to approach the center of the support frame 101 by the way of the inclined surface being in movable abutment with the abutting roller 207 and the sliding seat 204 slidingly cooperating with the sliding groove 201. The vertical plate 205 drives the abutting plate 209 to approach the middle of the support frame 101 by being connected to the sliding rod 208 and being connected to the second spring 210; when the abutting plate 209 starts to contact the outer wall of the concrete specimen 7, the guiding frame 211 continues to move downward, so that the vertical plate 205 continues to approach the middle of the support frame 101. Since the abutting plate 209 has already contacted the outer wall of the concrete specimen 7, the second spring 210 is compressed, so that the abutting plate 209 is closely attached to the outer wall of the concrete specimen 7. When the bottom of the protective frame 3 is matched with the abutting ring groove 102, the guiding frame 211 stops moving downward. At this time, the positions of the sliding seat 204 and the vertical plate 205 are fixed, and the four-wall positioning of the concrete specimen 7 can be realized. At the same time, by circumferentially distributing the abutting plates 209, the non-centered concrete specimen 7 can be pushed to the center of the support frame 101 during the positioning process of the concrete specimen 7, realizing the automatic centering positioning of the concrete specimen 7, which is convenient for subsequent strength detection; Among them, the guiding frame 211 is a right trapezoidal frame with an inclined surface facing the middle of the support frame 101, which can be effectively installed on the inner wall of the protection frame 3, and the width of the guiding frame 211 is the same as the width of the abutting roller 207, which can improve the abutting effect of the abutting roller 207.
[0030] In an embodiment of the present invention, referring to Figures 1 - 6 , the movable connection assembly 6 includes a number of limiting holes 601 provided on the column 104. Symmetrically installed at both ends of the top of the protection frame 3 are guiding cylinders 602. Symmetrically provided at both ends of the guiding cylinder 602 are guiding grooves 603. Symmetrically and slidably arranged in the guiding cylinder 602 are limiting rods 604. Connected to one end of the two limiting rods 604 close to each other is a third spring 606 provided inside the guiding cylinder 602. The outer end of the limiting rod 604 is movably matched with the limiting hole 601. Connected to one end of the two limiting rods 604 located inside the guiding cylinder 602 close to each other are movable rods 605 that are slidably matched with the guiding grooves 603. Symmetrically installed on the lifting plate 4 are J-shaped guiding plates 607 that are movably matched with the movable rods 605. The J-shaped guiding plate 607 is composed of an inclined plate and a semi-circular ring. The J-shaped guiding plate 607 is connected to the lifting plate 4 through a mounting frame 608.
[0031] In this embodiment, in the initial state, the protection frame 3 is at the highest point. At this time, the outer end of the limiting rod 604 abuts against the outer wall of the column 104, and the third spring 606 is in a compressed state. The movable rod 605 is located at the semi-circular ring of the J-shaped guiding plate 607, that is, the movable rod 605 and the J-shaped guiding plate 607 are in a clamped state, which can realize the synchronous lifting and lowering of the protection frame 3 and the lifting plate 4; When it is necessary to perform strength detection on the concrete specimen 7 placed on the support frame 101, the hydraulic cylinder 5 pushes the lifting plate 4 to move downward by means of the sliding fit between the lifting plate 4 and the column 104. The lifting plate 4 drives the J-shaped guiding plate 607 to move downward synchronously by means of being connected to the mounting frame 608. The J-shaped guiding plate 607 drives the limiting rod 604 and the protection frame 3 to move downward by means of being clamped with the movable rod 605 and the connection between the guiding cylinder 602 and the protection frame 3. The protection frame 3 drives the guiding frame 211 to move downward synchronously. The guiding frame 211 realizes the automatic centering and positioning of the concrete specimen 7 by means of the movable abutment with the abutting roller 207. When the protection frame 3 is matched with the abutting ring groove 102, at this time, the limiting rod 604 corresponds to the limiting hole 601, and the third spring 606 extends and pushes the limiting rod 604 to move outward, realizing the connection between the limiting rod 604 and the limiting rod 604, making the protection frame 3 in a positioned state, making the concrete specimen 7 in a sealed state. At the same time, the limiting rod 604 releases the clamping between the movable rod 605 and the J-shaped guiding plate 607 by driving the movable rod 605 to move outward synchronously, and releases the synchronous movement between the protection frame 3 and the lifting plate 4; When the hydraulic cylinder 5 continues to push the lifting plate 4 downward, at this time, the protective frame 3 remains stationary, and the lifting plate 4 drives the pressure sensor 401 downward to detect the strength of the concrete specimen 7; After the strength detection of the concrete specimen 7 is completed, the hydraulic cylinder 5 drives the lifting plate 4 to move upward. The lifting plate 4 drives the J-shaped guide plate 607 to move upward synchronously by connecting with the mounting frame 608. The J-shaped guide plate 607 drives the two limit rods 604 to approach each other through the sliding fit between the inclined plate and the movable rod 605 and the sliding fit between the movable rod 605 and the guide groove 603. The limit rods 604 release the connection between the limit rods 604 and the limit holes 601 by approaching each other. The third spring 606 is stressed and contracts, releasing the fixation of the position of the protective frame 3. At this time, the movable rod 605 is re-engaged with the semi-circular ring on the J-shaped guide plate 607, realizing the re-synchronous movement of the protective frame 3 and the lifting plate 4; When the hydraulic cylinder 5 continues to drive the lifting plate 4 to move upward, the lifting plate 4 drives the protective frame 3 to move upward synchronously by engaging with the movable rod 605 through the J-shaped guide plate 607, releasing the fit between the protective frame 3 and the abutting ring groove 102, facilitating the removal of the tested concrete specimen 7 and the cleaning of the surface of the support frame 101; During the downward movement of the protective frame 3 to the positioning position, automatic centering and positioning of the concrete specimen 7 can be achieved. That is, when detecting the strength of the concrete specimen 7, the tester only needs to first place the concrete specimen 7 to be tested on the support frame 101, and then control the hydraulic cylinder 5 to push the lifting plate 4 downward, so as to achieve automatic centering and positioning and strength detection of the concrete specimen 7. There is no need for the tester to perform too many steps, greatly simplifying the detection steps, and can well avoid the problem of inaccurate detection results caused by inaccurate operation steps, improving the detection efficiency and accuracy of the concrete specimen 7; Among them, several limit holes 601 are on the same horizontal plane, and the length of the guide groove 603 is the same as the projected length of the J-shaped guide plate 607 on the horizontal plane, which can ensure the effective cooperation between the movable rod 605 and the J-shaped guide plate 607. The axis of the limit hole 601 is parallel to the axis of the limit rod 604, which can ensure the effective connection between the limit rod 604 and the limit hole 601 and realize the fixation of the position of the protective frame 3.
