Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, and in particular to a steel reinforcement quality testing device for building engineering. Background Technology

[0002] In construction engineering, steel reinforcement serves as the primary load-bearing material, and its quality directly impacts the safety and durability of the entire building structure. Therefore, steel reinforcement must undergo rigorous performance testing before being put into use, including tensile strength, yield strength, elongation, and cold bending performance. Currently, common steel reinforcement testing equipment primarily includes tensile testing machines, used to test the longitudinal tensile strength of steel reinforcement.

[0003] In existing technologies, tensile strength testing and cold bending testing of reinforcing bars typically need to be performed on different equipment. This not only increases the complexity of the testing process and the cost of equipment investment, but also makes it difficult to simultaneously evaluate the cold bending performance of reinforcing bars under tensile conditions. Furthermore, tensile testing machines only perform a single tensile strength test, which cannot truly reflect the comprehensive performance of reinforcing bars under complex stress conditions. Utility Model Content

[0004] The purpose of this invention is to provide a steel reinforcement quality testing device for building engineering, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a steel reinforcement quality testing device for building engineering, comprising:

[0006] The tensile testing machine assembly has a worktable, two columns fixed to the top surface of the worktable, a lifting beam set between the two columns, and clamps respectively set on the bottom surface of the lifting beam and the top surface of the worktable.

[0007] The reinforcing bar to be inspected is clamped between two clamping pieces and subjected to longitudinal tensile testing by a tensile testing machine assembly;

[0008] The tensile strength auxiliary testing mechanism includes Z-axis guide rails symmetrically installed on the outer walls of two columns, a lifting beam plate slidably installed between the two Z-axis guide rails, a U-shaped clamping plate clamped to the periphery of the steel bar to be tested, and a hydraulic push-pull rod hinged between the U-shaped clamping plate and the lifting beam plate;

[0009] The hydraulic push-pull rod can apply force to the steel bar under test from multiple angles while it is being stretched, so that the tensile and cold bending test quality of the steel bar can be obtained by applying force to it at different angles through the hydraulic push-pull rod during the stretching process.

[0010] In this preferred embodiment, each column has a fixing plate bolted to its outer wall, and the two Z-axis guide rails are bolted to the surfaces of the two fixing plates respectively.

[0011] In this preferred embodiment, each of the Z-axis guide rails is slidably mounted with a lifting slider, and the lifting beam plate is fixedly mounted together with the two lifting sliders by bolts.

[0012] In this preferred embodiment, the U-shaped clamp is positioned horizontally to hold the reinforcing bars for inspection. The U-shaped clamp and the lifting beam are symmetrically welded with hinged ear plates on opposite sides. The two ends of the hydraulic push-pull rod are respectively hinged to the two sets of hinged ear plates via pins.

[0013] In a preferred embodiment of this scheme, after the U-shaped clamp holds the reinforcing bar for inspection, at least two fastening screws are symmetrically connected through the open end of the U-shaped clamp. Each fastening screw has a threaded end at its free end, and the threaded end extends to the outside of the U-shaped clamp and is locked with a connecting nut.

[0014] In this preferred embodiment, the workbench and the lifting beam are each fixedly mounted with a support base on opposite sides, and the two clamps are respectively fixed on the two support bases.

[0015] In this preferred embodiment, each clamping component includes a finger cylinder directly mounted on the free end of the support base and two clamping plates symmetrically arranged on the free end of the finger cylinder. The inner walls of the two clamping plates are longitudinally provided with clamping grooves for fitting and clamping the reinforcing bars to be inspected.

[0016] In this preferred embodiment, each of the clamping plates has a locking bolt installed through its outer wall, and the free end of each locking bolt passes through a snap-fit ​​groove and abuts against the outer wall of the reinforcing bar to be inspected.

[0017] In this preferred embodiment, both ends of the lifting beam are welded with L-shaped steel plates, and the vertically bent end of each L-shaped steel plate away from the lifting beam extends to the back of the column.

[0018] In this preferred embodiment, a steel wheel is rotatably mounted on the inner wall of the vertically bent end of each L-shaped steel plate, and the steel wheel makes rolling friction contact with the outer wall of the column.

[0019] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0020] This steel reinforcement quality testing equipment for building engineering integrates a tensile auxiliary testing mechanism into the tensile testing machine assembly. This allows the equipment to not only perform routine testing of the longitudinal tensile strength of steel reinforcement, but also to simultaneously apply lateral or inclined bending forces during or independently of the steel reinforcement under tension. This achieves a composite testing function for tensile and cold bending performance, enhancing the comprehensiveness of testing and its applicability in engineering projects. Traditional steel reinforcement testing equipment typically only has a single tensile testing capability and cannot simulate the cold bending performance of steel reinforcement under complex stress states in actual building structures. This solution, however, utilizes a U-shaped clamp, hydraulic push-pull rod, and a liftable lifting beam plate in synergy. This allows the steel reinforcement to be subjected to multi-angle push-pull forces at any set height position while being longitudinally stretched, realistically simulating the stress conditions of steel reinforcement at key structural points such as beam-column joints and bending points, thereby effectively assessing its structural reliability under composite stress states.

[0021] The design, which uses a Z-axis guide rail and a lifting slider to drive the lifting beam plate to slide up and down along the outer wall of the column, allows for flexible adjustment of the force application points of the hydraulic push-pull rod and U-shaped clamping plate in the vertical direction. This enables cold bending testing of the reinforcing bars at different heights, achieving a comprehensive evaluation of the consistency of cold bending performance along the length of the reinforcing bars. This structure allows operators to select testing points according to actual project needs, avoiding the limitations of traditional fixed cold bending devices that can only apply force at a single location, significantly improving the flexibility and specificity of the testing.

[0022] By using hinged lugs at both ends of the hydraulic push-pull rod, which are respectively hinged to the lifting beam and the U-shaped clamp, the push-pull rod can automatically adapt to angle changes during lifting and lowering, achieving dynamic adjustment of the direction of the push-pull force. This achieves the technical effect of applying an inclined bending force to simulate complex loads under the tension of the reinforcing steel. When the lifting beam rises or falls, the hydraulic push-pull rod extends and retracts accordingly, changing its angle with the horizontal plane. This pushes the U-shaped clamp to act on the reinforcing steel in an inclined direction, simulating the asymmetric bending moment of the reinforcing steel in actual structures due to eccentric force or node connections, further enhancing the realism of the test and its engineering guidance significance.

Detailed Implementation

[0032] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0033] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0034] This embodiment provides, for example Figures 1 to 6 The illustrated equipment for testing the quality of reinforcing steel bars in building construction includes a tensile testing machine assembly 1, reinforcing steel bars 7 to be tested, and a tensile auxiliary testing mechanism 8. The tensile testing machine in this embodiment is a conventional testing machine (the lifting action of the lifting beam 4 follows the tensile principle of a conventional tensile testing machine, which will not be elaborated here). The specific model needs to be selected according to the actual application.

[0035] The tensile testing machine assembly 1 includes a worktable 2, two columns 3 fixed to the top surface of the worktable 2, a lifting beam 4 disposed between the two columns 3, and clamping parts 6 disposed on the bottom surface of the lifting beam 4 and the top surface of the worktable 2, respectively. A control panel 5 is installed on the outer wall of one of the columns 3. The control panel 5 contains a PLC for controlling the opening and closing of various electronic devices in this embodiment. The reinforcing bar 7 to be tested is clamped between the two clamping parts 6 and subjected to longitudinal tensile testing by the tensile testing machine assembly 1. The tensile auxiliary testing mechanism 8 includes Z-axis guide rails 10 symmetrically installed on the outer walls of the two columns 3, a lifting beam plate 12 slidably installed between the two Z-axis guide rails 10, a U-shaped clamping plate 13 clamped to the periphery of the reinforcing bar 7 to be tested, and a hydraulic push-pull rod 14 hinged between the U-shaped clamping plate 13 and the lifting beam plate 12.

[0036] In this embodiment, the hydraulic push-pull rod 14 can push and pull force on the steel bar 7 under the tensile test from multiple angles, so that the tensile and cold bending test quality of the steel bar 7 can be obtained by pushing and pulling force at different angles of the hydraulic push-pull rod 14 during the tensile process. When the reinforcing bar 7 is subjected to longitudinal tensile testing to assess its tensile strength, cold bending testing can be performed simultaneously or not. Cold bending testing can be used alone when the reinforcing bar 7 is not under tension. During simultaneous cold bending testing, the reinforcing bar 7 is stretched. At this time, the hydraulic push-pull rod 14 horizontally pushes and pulls the U-shaped clamp 13 as needed, causing the U-shaped clamp 13 to push and pull the reinforcing bar 7, thus testing the cold bending performance at horizontal points. When it is necessary to tilt the reinforcing bar 7 to simulate the load-bearing capacity at different points, the Z-axis guide rail 10 drives the lifting slider 11 to raise and lower the lifting beam plate 12 to select the required height position. When the lifting beam plate 12 rises and falls, the hydraulic push-pull rod 14 synchronously extends and retracts, thus cooperating with the lifting beam plate 12 to create an inclination between the U-shaped clamp 13 and the lifting beam plate 12, tilting upwards or downwards. Figure 3 The upward tilt of the hydraulic push-pull rod 14 causes it to push and pull the U-shaped clamp 13, which in turn pushes and pulls the reinforcing bar 7 under test, thereby detecting the cold bending and simulated load bearing capacity at different points on the reinforcing bar 7. When the reinforcing bar 7 under test is not stretched and is used for cold bending testing alone, the tensile auxiliary testing mechanism 8 can also be used to detect the cold bending performance of the reinforcing bar 7 under test and simulate the load bearing capacity at different points.

[0037] In this embodiment, each column 3 has a fixing plate 9 bolted to its outer wall, and two Z-axis guide rails 10 are bolted to the surfaces of the two fixing plates 9 respectively.

[0038] In this embodiment, a lifting slider 11 is slidably installed on the outer wall of each Z-axis guide rail 10, and the lifting beam plate 12 is fixedly installed together with the two lifting sliders 11 by bolts.

[0039] In this embodiment, the U-shaped clamping plate 13 is positioned horizontally to hold the reinforcing bar 7 for inspection. Hinged ear plates 15 are symmetrically welded to opposite sides of both the U-shaped clamping plate 13 and the lifting beam plate 12. The two ends of the hydraulic push-pull rod 14 are respectively hinged to the two sets of hinged ear plates 15 via pins. The hydraulic push-pull rod 14 is a double-ear type. Furthermore, the specific model of the hydraulic push-pull rod 14 needs to be selected based on the parameters of the reinforcing bar being inspected. The required thrust of the hydraulic push-pull rod 14 needs to be determined based on the material, diameter, and expected bending angle of the reinforcing bar required in the actual construction situation, thus selecting the hydraulic push-pull rod 14 required for the actual situation. The selection of the required model based on the actual situation will not be elaborated further here.

[0040] In this embodiment, after the U-shaped clamping plate 13 clamps the reinforcing bar 7 to be inspected, at least two fastening screws 16 are symmetrically connected through the open end of the U-shaped clamping plate 13. Each fastening screw 16 has a threaded end 17 at its free end, which extends to the outside of the U-shaped clamping plate 13 and is locked with a connecting nut. The design of the fastening screws 16 is to reduce the deformation of the U-shaped clamping plate 13. Through the design of the U-shaped clamping plate 13 cooperating with the fastening screws 16 and the threaded end 17 for locking, the clamping plate can firmly hold the reinforcing bar 7 to be inspected without slippage or deformation, realizing the function of applying a stable bending force to the reinforcing bar and preventing data distortion caused by insecure clamping during the inspection process. This structure effectively enhances the overall rigidity of the U-shaped clamping plate 13, reduces its elastic deformation under stress, ensures that the applied bending force is accurately transmitted to the reinforcing bar body, and improves the inspection accuracy.

[0041] In this embodiment, support seats 21 are fixedly installed on opposite sides of the workbench 2 and the lifting beam 4, and two clamps 6 are respectively fixed on the two support seats 21.

[0042] In this embodiment, each clamp 6 includes a finger cylinder directly mounted on the free end of the support base 21 and two clamping plates 18 symmetrically arranged on the free end of the finger cylinder. The inner walls of the two clamping plates 18 are longitudinally provided with clamping grooves 20 for fitting and clamping the reinforcing bar 7 to be inspected. The model of the finger cylinder needs to be selected according to the actual situation, and the clamping force of the finger cylinder needs to be greater than the tensile force on the reinforcing bar 7 to be inspected.

[0043] In this embodiment, each clamping plate 18 has a locking bolt 19 installed through its outer wall. The free end of each locking bolt 19 passes through the snap-fit ​​groove 20 and abuts against the outer wall of the reinforcing bar 7 to be inspected.

[0044] In this embodiment, L-shaped steel plates 22 are welded to both ends of the lifting beam plate 12. The vertically bent end of each L-shaped steel plate 22 extends away from the lifting beam plate 12 to the back of the column 3. A steel wheel 23 is rotatably mounted on the inner wall of the vertically bent end of each L-shaped steel plate 22, and the steel wheel 23 makes rolling friction contact with the outer wall of the column 3. By hanging the L-shaped steel plate 22 on the back of the column 3, the L-shaped steel plate 22 can limit the lifting beam plate 12 and prevent the lifting beam plate 12 from falling off when the hydraulic push rod 14 pushes it. When the Z-axis guide rail 10 drives the lifting beam plate 12 to move up and down, the steel wheel 23 rolls on the back of the column 3 and moves with the lifting beam plate 12. By installing L-shaped steel plates 22 at both ends of the lifting beam 12 and steel wheels 23 that roll in contact with the outer wall of the column 3 at their vertically bent ends, the entire tensile auxiliary testing mechanism achieves good lateral stability during lifting and stress. This prevents the lifting beam 12 from shifting or falling off due to the thrust of the hydraulic push-pull rod 14, thereby improving the safety and structural reliability of the equipment. The steel wheels 23 roll on the back of the column 3, providing lateral support without affecting the vertical movement of the lifting slider 11.

[0045] In this embodiment, the Z-axis guide rail 10 and the hydraulic push-pull rod 14 are synchronously controlled: Parameters such as the height position and tilt angle to be tested are set according to the testing requirements. These parameters determine the position that the lifting beam plate 12 needs to reach and the angle and length that the hydraulic push-pull rod 14 needs to adjust. The PLC controls the Z-axis guide rail 10 to start working, driving the lifting slider 11 to move up and down along the guide rail, thereby driving the lifting beam plate 12 to the predetermined height position. This process is to ensure that the U-shaped clamping plate 13 can accurately clamp onto the designated position of the reinforcing bar 7 to be inspected. The synchronous PLC control system controls the hydraulic push-pull rod 14 to perform corresponding extension and retraction actions according to the preset angle or displacement requirements. If a horizontal force needs to be applied to the reinforcing bar, the hydraulic push-pull rod 14 maintains its original length or is slightly adjusted; if a tilting force needs to be applied, the hydraulic push-pull rod 14 will automatically extend or shorten according to the required angle to ensure that the U-shaped clamping plate 13 can contact the reinforcing bar at the correct angle and apply the required bending force.

[0046] Working principle

[0047] The steel reinforcement quality testing equipment for this construction project places the steel reinforcement 7 to be tested between the upper and lower clamps 6. The finger cylinder in the clamp 6 is activated to drive the two clamping plates 18 to close, clamping the steel reinforcement. The clamping plates 18 are further locked by the locking bolts 19 to prevent the steel reinforcement from slipping during the tensile process. The tensile parameters (such as tensile speed, maximum tensile force, etc.) of the tensile testing machine assembly 1 are set according to the testing requirements. The tensile testing machine assembly 1 is started, and the lifting beam 4 drives the upper clamp 6 to move upward, applying longitudinal tensile force to the steel reinforcement. The tensile force gradually increases, and the system in the tensile testing machine assembly 1 records the tensile force value and the elongation of the steel reinforcement in real time. When the steel reinforcement reaches its ultimate strength and breaks, the maximum tensile force value is recorded, and the tensile strength of the steel reinforcement is calculated.

[0048] When cold bending and tensile testing are performed simultaneously: During the stretching process of the reinforcing bar, the tensile auxiliary testing mechanism 8 is activated. The PLC in the control panel 5 controls the Z-axis guide rail 10 to drive the lifting slider 11 to slide up and down along the guide rail, causing the lifting beam plate 12 to reach the preset height. The U-shaped clamping plate 13 is clamped at the designated position of the reinforcing bar 7 to be tested. The hydraulic push-pull rod 14 is connected to the lifting beam plate 12 through the hinge ear plate 15, and applies a push-pull force to the U-shaped clamping plate 13. The push-pull direction can be horizontal or inclined (adjusted between the lifting beam plate 12 and the hydraulic push-pull rod 14). The U-shaped clamping plate 13 applies a transverse or inclined force to the reinforcing bar, simulating the cold bending of the reinforcing bar at different stress points in actual engineering. By observing whether cracks, fractures or other defects appear at the bending part of the reinforcing bar, its cold bending performance can be judged. The test can be repeated at different height positions to simulate the cold bending performance of the reinforcing bar at different stress points.

[0049] When cold bending test is performed alone (without tensile test): the steel bar to be tested 7 is clamped between the clamps 6, but the tensioning action is not initiated. The Z-axis guide rail 10 is started to drive the lifting beam plate 12 to the specified height. The U-shaped clamp plate 13 is clamped on the surface of the steel bar. The hydraulic push-pull rod 14 applies the push-pull force. The cold bending stress of the steel bar at different angles and heights is observed to determine its cold bending performance. It can be used to test the cold bending limit and plastic deformation capacity of the steel bar in the unstretched state.

[0050] L-shaped steel plate 22 and steel wheel 23 form the limiting structure of lifting beam plate 12. When the hydraulic push rod 14 applies a thrust, L-shaped steel plate 22 rolls into contact with column 3 through steel wheel 23 to prevent lifting beam plate 12 from falling off. Z-axis guide rail 10 cooperates with lifting slider 11 to ensure that lifting beam plate 12 moves smoothly during lifting. Fixed plate 9 is fixed to column 3 by bolts to ensure the stability of the entire tensile auxiliary detection mechanism 8.

[0051] After the test is completed, shut down the tensile testing machine assembly 1 and the tensile auxiliary testing mechanism 8, remove the broken or deformed reinforcing bar 7, and replace it with a new reinforcing bar for the next round of testing.
