Description
Technical Field
[0001] The present invention relates to the technical field of building component detection, in particular to a device for detecting strength of assembled building components. Background Art
[0002] Prefabricated building components (hereinafter referred to as building components) refer to building structural parts that are pre-processed and manufactured in factories. Building components have been widely used in the field of modern construction due to their advantages such as high efficiency, environmental protection, and controllable quality. As the core component of prefabricated buildings, the quality and strength of building components are directly related to the safety and stability of the entire building structure. Therefore, strength testing of building components is required.
[0003] When testing the strength of building components, multiple test points are usually marked on the building components. The operator then controls the rebound hammer to perform strength tests on the multiple test points of the building components in sequence. Finally, the test data of the rebound hammer is analyzed to determine whether the strength of the building components is qualified.
[0004] The following problems may exist when conducting strength tests on building components: 1. To ensure the accuracy of the strength test results of building components, a large number of test points usually need to be marked on the building components. When the operator controls the rebound hammer to perform strength tests on multiple test points on the building components in sequence, there may be a problem of a small inclination angle between the rebound hammer and the component surface due to human fatigue, which in turn leads to a large discreteness of the rebound value, affecting the accuracy of the test results; 2.

[0029] The embodiments described below are exemplary and are only used to explain the present invention, and are not to be construed as limiting the present invention. If no specific techniques or conditions are specified in the embodiments, the techniques or conditions described in the literature in the art or the product instructions shall be followed.
[0030] See Figure 1 A strength testing device for prefabricated building components includes an integrated board 1, a rebound hammer 5 is distributed on the front side of the integrated board 1, two fixed units 2 arranged symmetrically on the left and right are installed at the front end of the integrated board 1, an adjustment unit 3 is installed in the middle of the front end of the integrated board 1, a calibration unit 4 is installed on the adjustment unit 3, the adjustment unit 3 is used to adjust the position of the calibration unit 4, and the calibration unit 4 and the rebound hammer 5 are connected.
[0031] The present invention is used to detect the strength of building components. The present invention can quickly and stably install the rebound hammer 5 at the detection position corresponding to the surface of the building component, and by adjusting the position of the rebound hammer 5, the rebound hammer 5 can perform strength detection on each detection point of the building component in turn, preventing the rebound hammer 5 from forming a small inclination angle with the component surface due to human fatigue. The present invention can also make the rebound hammer 5 perpendicular to the surface of the building component, thereby ensuring the accuracy of the strength detection result of the building component.
[0032] Specifically, the integrated board 1 is first placed at a position corresponding to the inspection position of the building component, so that the rebound hammer 5 corresponds to the inspection position of the building component, and then the integrated board 1 and the building component are fixed together by the fixing unit 2, so that the rebound hammer 5 is installed at the inspection position corresponding to the building component, and then the control and adjustment unit 3 adjusts the position of the rebound hammer 5 in sequence through the calibration unit 4, so that the rebound hammer 5 can be moved to the corresponding position of each inspection point of the building component in sequence, and the control and adjustment unit 3 uses the calibration unit 4 to make the rebound hammer 5 perform strength detection on each inspection point of the building component, and the calibration unit 4 can make the rebound hammer 5 perpendicular to the surface of the building component. After the strength detection of each inspection point of the building component is completed, the integrated board 1 is removed from the building component by controlling the fixing unit 2, and the detection data of the rebound hammer 5 is manually analyzed to determine whether the strength of the building component is qualified, thereby realizing the strength detection of the building component.
[0033] See Figure 1 and Figure 2 The fixing unit 2 includes an annular cylinder 21 which is slidably installed at the left and right ends of the front side of the integrated board 1 through multiple guide rods. An annular groove is provided on the front side of the annular cylinder 21. A sealing filling ring 23 made of rubber is installed in the annular groove through a tightening mechanism 22, and the tightening mechanism 22 is connected to the integrated board 1. The tightening mechanism 22 is used to press the sealing filling ring 23 against the surface of the building component. A sealing plate 24 is slidably installed on the inside of the annular cylinder 21, and a pull rod 25 is fixedly installed on the rear side of the sealing plate 24. The rear end of the pull rod 25 slides back and forth through the integrated board 1, and a limiting mechanism 26 for limiting the position of the pull rod 25 is installed on the rear side of the integrated board 1 corresponding to the position of the pull rod 25; wherein, the size of the cavity inside the annular cylinder 21 is set to be larger.
[0034] The fixing unit 2 is used to quickly fix the integrated board 1 on the building component; specifically, when the integrated board 1 is placed at a position corresponding to the detection position of the building component, the front side of the annular cylinder 21 and the front side of the sealing filling ring 23 are attached to the surface of the building component, and the integrated board 1 is manually pressed forward so that the integrated board 1 presses the sealing filling ring 23 against the surface of the building component through the tightening mechanism 22. Since the surface of the building component is uneven and the sealing filling ring 23 is made of rubber, when the integrated board 1 is pressed forward, the tightening mechanism 22 can also squeeze the sealing filling ring 23 in the direction close to the building component, so that the sealing filling ring 23 fills the uneven surface of the building component, thereby forming a sealed cavity inside the annular cylinder 21.
[0035] Then, the pulling rod 25 is manually controlled to move backward, so that the pulling rod 25 drives the sealing plate 24 to move backward, and the air pressure inside the annular cylinder 21, between the sealing plate 24 and the building component is reduced. The limiting mechanism 26 can limit the position of the pulling rod 25, so that the pulling rod 25 cannot move forward, and the size of the cavity inside the annular cylinder 21 is set larger, so that the annular cylinder 21 can be stably fixed on the building component, and the integrated board 1 can be quickly fixed at a position corresponding to the detection position of the building component.
[0036] After the strength test of multiple test points of the building component is completed, the position of the pull-out rod 25 is no longer limited by controlling the limit mechanism 26, and the pull-out rod 25 is manually pushed forward, so that the pull-out rod 25 drives the sealing plate 24 to move forward, so that the annular cylinder 21 is no longer fixed on the building component, and the integrated board 1 can be quickly removed.
[0037] See Figure 2 and Figure 3 The tightening mechanism 22 includes a tightening ring 221 fixedly mounted on the rear side of the sealing filling ring 23, and the tightening ring 221 is slidably mounted in the annular groove. A transmission ring 223 is slidably mounted on the rear side of the tightening ring 221 through multiple circumferentially evenly arranged elastic tightening rods 222, and the transmission ring 223 is distributed in the annular groove. A plurality of circumferentially evenly arranged arc grooves are opened on the rear side of the transmission ring 223, and an arc slider is slidably mounted in the arc groove through an arc-structured return spring 224. A transmission rod 225 is fixedly mounted on the rear side of the arc slider, and the rear side of the transmission rod 225 slides back and forth through the annular cylinder 21 and is fixedly connected to the integrated board 1.
[0038] The tightening mechanism 22 is used to press the sealing filling ring 23 against the surface of the building component; specifically, when the integrated board 1 is manually pressed forward, the integrated board 1 drives the transmission ring 223 to move forward through the transmission rod 225, and since the sealing filling ring 23 is in contact with the surface of the building component, the transmission ring 223 moves forward relative to the tightening ring 221, and at the same time the elastic tightening rod 222 is compressed, so that the tightening ring 221 presses the sealing filling ring 23 against the surface of the building component under the elastic action of the elastic tightening rod 222. At the same time, as the compression amount of the elastic tightening rod 222 increases, the tightening ring 221 can squeeze the sealing filling ring 23 forward, so that the sealing filling ring 23 fills the uneven surface of the building component. When the integrated board 1 is removed from the building component, the transmission ring 223 can return to its initial position backward under the action of the elastic tightening rod 222.
[0039] See Figure 3 A plurality of circumferentially evenly arranged toggle block groups 211 are fixed in the annular groove of the annular cylinder 21. Each group of toggle block groups 211 includes a plurality of toggle blocks evenly arranged front and back, and the two adjacent toggle blocks are staggered in the circumference, and the front and rear ends of the opposite sides of the two adjacent toggle blocks are set as inclined surfaces.
[0040] See Figure 3 A plurality of circumferentially evenly arranged matching column blocks 226 are fixedly mounted on the outside of the transmission ring 223. The matching column blocks 226 are used to cooperate with the inclined surface of the toggle block to drive the transmission ring 223 to rotate back and forth.
[0041] When the transmission ring 223 moves forward relative to the clamping ring 221, the transmission ring 223 drives the matching column block 226 to move forward. When the matching column block 226 moves to the corresponding position of the toggle block, the matching column block 226 and the toggle block inclined surface cooperate to drive the transmission ring 223 to rotate and compress the reset spring 224. Since the two adjacent toggle blocks are arranged circumferentially staggered, when the matching column block 226 moves to the corresponding position of the next adjacent toggle block, the matching column block 226 and the toggle block inclined surface cooperate to drive the transmission ring 223 to rotate to the initial position.
[0042] There are multiple toggle blocks, so that the transmission ring 223 drives the sealing filling ring 23 to rotate back and forth through the elastic holding rod 222 and the holding ring 221. At the same time, since the sealing filling ring 23 is in contact with the surface of the building component, the reciprocating sealing filling ring 23 can clean the impurities between it and the surface of the building component, ensuring that the sealing filling ring 23 can be closely fitted with the surface of the building component, and further ensuring that the annular cylinder 21 can be stably fixed on the building component. When the transmission ring 223 returns to its initial position, the transmission ring 223 can also rotate to its initial position under the action of the return spring 224.
[0043] See Figure 2 、 Figure 4 and Figure 5 The limiting mechanism 26 includes a connecting sleeve 261 fixedly installed on the rear side of the integrated board 1 through multiple fixing rods, and the pulling rod 25 is located in the connecting sleeve 261. A plurality of circumferentially evenly arranged limiting blocks 262 are radially slidably installed on the inner side of the connecting sleeve 261. The plurality of limiting blocks 262 radially slide on opposite sides to penetrate the connecting sleeve 261 and are connected to the connecting sleeve 261 with a guide spring 263.
[0044] See Figure 4 and Figure 5 The part of the pull rod 25 located on the rear side of the integrated board 1 is fixedly installed with multiple groups of ratchet groups 251 that are evenly arranged circumferentially. Each group of ratchet groups 251 includes multiple ratchets evenly arranged front and back. The ratchets are used to cooperate with the limit block 262 to limit the position of the pull rod 25; wherein the ratchets can move backward relative to the limit block 262.
[0045] The limiting mechanism 26 is used to limit the position of the pull-out rod 25; specifically, when the integrated board 1 is manually pressed forward, the integrated board 1 drives the connecting sleeve 261 to move forward relative to the pull-out rod 25 through the fixed rod. When the connecting sleeve 261 drives the limiting block 262 to move to the position corresponding to the ratchet, the limiting block 262 moves away from the pull-out rod 25 under the action of the ratchet and stretches the guide spring 263, thereby not interfering with the manual forward pressing of the integrated board 1.
[0046] When the pulling rod 25 is manually controlled to move backward, the pulling rod 25 drives the ratchet to move backward relative to the limit block 262. When the pulling rod 25 drives the ratchet to move to the corresponding position of the limit block 262, the limit block 262 moves again in the direction away from the pulling rod 25 under the action of the ratchet and stretches the guide spring 263, so as not to interfere with the backward movement of the pulling rod 25. When the manually controlled pulling rod 25 drives the sealing plate 24 to move backward, the limit block 262 can be moved to the front side of the ratchet corresponding to its position at this time under the action of the guide spring 263. The limit block 262 and the ratchet cooperate to prevent the pulling rod 25 from moving forward, thereby limiting the position of the pulling rod 25.
[0047] See Figure 4 and Figure 5 Two symmetrically arranged unlocking column blocks 264 are fixedly installed on the back sides of multiple limit blocks 262. An unlocking sleeve 265 is provided on the outside of the connecting sleeve 261 through multiple connecting springs 267 to slide up and down. An unlocking plate 266 is fixedly installed on the front side of the unlocking sleeve 265 corresponding to the position of the unlocking column block 264. The front end of the unlocking plate 266 is set to an inclined surface that matches the unlocking column block 264.
[0048] When the strength test of multiple test points of the building component is completed, the unlocking sleeve 265 is manually pressed forward and the connecting spring 267 is compressed, so that the unlocking sleeve 265 drives the unlocking plate 266 to move forward, and then the inclined surface of the unlocking plate 266 and the unlocking column block 264 cooperate to drive multiple limit blocks 262 to move away from each other and separate from the ratchet, thereby quickly releasing the limit on the pull-out rod 25, and then the pull-out rod 25 can be manually pushed forward, so that the pull-out rod 25 drives the sealing plate 24 to move forward, so that the annular cylinder 21 is no longer fixed on the building component, and the integrated board 1 can be quickly removed, further increasing the efficiency of the strength test of the building component.
[0049] See Figure 1 、 Figure 2 and Figure 6The calibration unit 4 includes a connecting plate 41 installed on the adjustment unit 3. The middle part of the front end of the connecting plate 41 is connected to the rebound test hammer 5. Two calibration plates 42 symmetrically arranged up and down are installed on the front side of the connecting plate 41 through a connecting piece, and the front end of the calibration plate 42 is set to be used for grinding the surface of the building component. The rear side of the two calibration plates 42 is installed with a matching mechanism 45, which is used to drive the calibration plates 42 to move back and forth up and down.
[0050] See Figure 1 、 Figure 2 and Figure 6 The adjustment unit 3 includes an adjustment slide frame 31 that is slidably installed left and right in a square hole preset in the middle of the integrated board 1. An adjustment plate 33 is slidably installed up and down in the adjustment slide frame 31 through an adjustment member 32. The front end of the adjustment plate 33 is slidably installed with a transmission plate 35 through two elastic pressing rods 34 arranged symmetrically on the left and right, and the rear ends of the two elastic pressing rods 34 slide back and forth through the adjustment plate 33 and are fixedly installed with a pressing plate 36. The front end of the transmission plate 35 is hinged with a U-shaped frame 37, and the connecting plate 41 is rotatably installed in the U-shaped frame 37; wherein, the transmission plate 35 can rotate left and right based on the hinge between it and the U-shaped frame 37, and the hinge between the transmission plate 35 and the U-shaped frame 37 and the rotation connection between the connecting plate 41 and the U-shaped frame 37 are all connected by torsion springs.
[0051] See Figure 6 A triangular guide plate 421 is fixedly mounted on the back sides of the two leveling plates 42 .
[0052] It should be noted that the adjustment member 32 in the present invention adopts an adjustment screw, which is connected to the adjustment plate 33 by threaded fitting, and the adjustment screw and the adjustment slide frame 31 are rotatably connected. The up and down position adjustment of the adjustment plate 33 is achieved by rotating the adjustment screw. At the same time, a certain friction force is set at the sliding connection between the adjustment slide frame 31 and the integrated board 1. When an external force for moving the adjustment slide frame 31 left and right is applied to the adjustment slide frame 31, the adjustment slide frame 31 can slide left and right relative to the integrated board 1. When no external force for moving the adjustment slide frame 31 left and right is applied, the adjustment slide frame 31 can be in a stationary state relative to the integrated board 1.
[0053] The calibration unit 4 is used to make the rebound hammer 5 perpendicular to the surface of the building component, and the adjustment unit 3 is used to adjust the position of the calibration unit 4; specifically, when the integrated board 1 is fixed at the position corresponding to the building component detection position, the adjustment slide frame 31 is toggled left and right, so that the adjustment slide frame 31 finally drives the rebound hammer 5 to move left and right through the adjustment plate 33, thereby realizing the left and right position adjustment of the rebound hammer 5, and controlling the adjustment member 32 to drive the rebound hammer 5 to move up and down through the adjustment plate 33, so that the rebound hammer 5 can perform strength detection on multiple detection points of the building component in sequence.
[0054] When the strength test is performed on the test points of the building component, the pressing plate 36 is pushed forward, and the pressing plate 36 finally drives the calibrating plate 42 to move forward through the elastic pressing rod 34 and the transmission plate 35. At the same time, since the connecting plate 41 is rotatably installed in the U-shaped frame 37, and the U-shaped frame 37 and the transmission plate 35 are hinged, when the calibrating plate 42 is attached to the surface of the building component, the connecting plate 41 moves forward relative to the calibrating plate 42, and the calibrating plate 42 can calibrate the position of the connecting plate 41 through the connecting piece, so that the calibrating plate 42 and the surface of the building component are parallel, and then the rebound hammer 5 and the surface of the building component are perpendicular.
[0055] At the same time, when the rebound tester 5 moves to the surface of the building component, the matching mechanism 45 can drive the leveling plate 42 to move back and forth up and down, so that the front end of the leveling plate 42 can grind the surface of the building component, thereby removing impurities such as release agent residue or dust on the surface of the building component, ensuring the flatness of the surface of the building component, and increasing the efficiency of the strength detection of the building component. When the two leveling plates 42 move away from each other, the impurity particles generated after grinding the surface of the building component can be moved to the left and right sides of the leveling plate 42 under the action of the triangular structure of the guide plate 421, thereby preventing impurities from remaining at the detection point of the building component, further ensuring the flatness of the surface of the building component. At the same time, the matching mechanism 45 can also keep the two leveling plates 42 in a separated state, which will not affect the strength detection of the building component by the rebound tester 5.
[0056] When the inspection of one inspection point of the building component is completed, the pressing plate 36 is released, so that the pressing plate 36 returns to the initial position under the action of the elastic pressing rod 34, and then the elastic pressing rod 34 drives the rebound tester 5 and the leveling plate 42 to move backward to the initial position through the transmission plate 35.
[0057] See Figure 2 、 Figure 6 and Figure 7 The mating mechanism 45 includes two symmetrically arranged square plates 451 fixedly mounted on the rear sides of the two leveling plates 42. A plurality of mating blocks 452 evenly arranged front and rear are fixedly mounted on the rear end of the square plate 451 near the middle of the connecting plate 41. A separation block 453 is fixedly mounted on the front end of the square plate 451 near the middle of the connecting plate 41. An L-shaped plate 411 is fixedly mounted at the position on the front side of the connecting plate 41 corresponding to the mating block 452. The front and rear ends of the mating block 452 near the middle of the connecting plate 41 and the rear end of the separation block 453 near the middle of the connecting plate 41 are all set to be inclined surfaces that match the vertical section of the L-shaped plate 411.
[0058] See Figure 6 and Figure 7 The connecting member includes two elastic levers 43 symmetrically arranged on the left and right sides of the leveling plate 42 , and the elastic levers 43 are connected to the connecting plate 41 by sliding up and down through the extension spring 44 .
[0059] The matching mechanism 45 is used to drive the leveling plate 42 to move back and forth up and down; specifically, when the connecting plate 41 moves forward relative to the leveling plate 42, and before the rebound tester 5 moves to the surface of the building component, the connecting plate 41 drives the L-shaped plate 411 to move forward relative to the leveling plate 42, and when the vertical section of the L-shaped plate 411 moves to the corresponding position of the matching block 452, the vertical section of the L-shaped plate 411 and the inclined surface of the matching block 452 cooperate to drive the two leveling plates 42 to move away from each other, so that the leveling plate 42 drives the elastic yield rod 43 to move synchronously and compress the extension spring 44, and when the vertical section of the L-shaped plate 411 and the inclined surface of the matching block 452 are separated, the elastic yield rod 43 drives the leveling plate 42 to return to its initial position under the action of the extension spring 44, and there are multiple matching blocks 452, so that the leveling plate 42 can continue to move back and forth up and down.
[0060] When the connecting plate 41 drives the vertical section of the L-shaped plate 411 to move to the corresponding position of the separation block 453, the vertical section of the L-shaped plate 411 can cooperate with the inclined surface of the separation block 453 to drive the two leveling plates 42 to move away from each other, and the vertical section of the L-shaped plate 411 can continue to cooperate with the separation block 453 to ensure that the two leveling plates 42 are always in a state of moving away from each other. Then the connecting plate 41 drives the rebound tester 5 to move to the surface of the building component and perform strength testing on the building component.
[0061] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
