Description

Technical Field

[0001] The present invention relates to the on-site detection technology of the strength and residual stress of glass curtain walls, and specifically relates to a rigid integral tooling detection device and a detection method for on-site detection of glass strength and residual stress. Background Art

[0002] As an important material integrating structure and function, glass materials have been widely used in the construction field. When glass is subjected to tensile stress, it will continuously undergo elastic deformation until it reaches the failure limit and breaks. Moreover, the brittle characteristics of glass are obvious, the tensile strain limit value is low, and the strength shows significant non-uniformity. Therefore, the mechanical properties and residual stress of glass materials directly affect the durability and safety of glass. The on-site detection of components in actual engineering structures is particularly important and urgent.

[0003] It has been proven that the fracture strength of brittle materials such as glass can be estimated through simple contact tests. According to the Hertz indentation theory, the local strength of glass is usually controlled by the critical stress state. Based on this, the relationship between the local strength of glass and the critical indentation load is established to evaluate the local strength of glass. Therefore, the glass indentation method realizes the micro-damage on-site detection of the mechanical properties and residual stress of glass components. With the help of a spherical indenter loading device, standard test samples and laboratory conditions are not required.

[0004] However, some limitations and deficiencies have emerged in the existing glass on-site detection devices and methods. 1. Insufficient rigidity and stability of the adsorption structure: The existing devices use simple fixed bases and brackets, with insufficient rigidity. During detection, the reaction force will cause deformation and loosening of the equipment, thus introducing errors; 2. Poor adsorption effect: The existing devices use suction cups to adsorb on the glass surface, relying on rotating the handle to apply pressure, with poor pressure control accuracy, low efficiency, and dependence on manual operation, which is not suitable for on-site operation; 3. The adjustment of the measuring point position is not flexible enough: Once the existing devices are installed, only a single measuring point can be detected. For the detection of multiple measuring points at different positions, the detection device must be repeatedly disassembled and assembled, and the procedure is relatively cumbersome; 4. The test lacks key parameters: The existing devices lack recommendations for relevant parameters such as indenter size and indentation depth for the detection of glass strength and residual stress; 5. There is uncertainty in obtaining the critical load: The existing devices need to obtain the critical load to test the glass strength, and the critical load needs to use an acoustic emission signal device to obtain the sound signal generated when the glass crack initiates, which will be affected by noise and affect the detection results. Summary of the Invention

[0005] Objective of the Invention: The present invention provides an on-site inspection rigid integral tooling inspection device and method for the mechanical properties of glass, which overcomes the limitations of insufficient rigidity and poor adsorption force of traditional devices, adapts to glass plates with different inclination angles, overcomes the limitations of the use scenario, simplifies manual operation, and realizes on-site inspection; realizes multi-measurement point displacement adjustment, realizes one-time fixation and multi-point detection; the indenter of the portable mechanical property tester adopts a replaceable spherical tungsten carbide indenter, which provides the key parameters of the indenter size and the penetration depth into the glass required for testing, and further improves the testing efficiency and accuracy.

[0006] Technical Solution Adopted by the Present Invention: An on-site inspection rigid integral tooling inspection device and method for the mechanical properties of glass, including a suction cup tooling, a suction cup, a dovetail slider, a portable mechanical property tester, a suction cup fixing bolt, a slider fixing bolt, and a tester fixing bolt;

The suction cup tooling is connected to the dovetail slider through a slider fixing bolt. The dovetail slider is connected to the portable mechanical property tester through a tester fixing bolt and moves in the X and Y coordinates during the measurement of the portable mechanical property tester to realize the position adjustment of the test point; the portable mechanical property tester is equipped with a spherical indenter, and the vertical downward pressure of the spherical indenter is controlled by an electronic device to contact the surface of the glass to be inspected, realizing micro-damage measurement.

[0008] Preferably, there are a total of four suction cups, and there are a total of two suction cup toolings as the force-bearing members of the entire structure. The suction cup tooling is a structure with a middle web and steel profiles at both ends. A bolt hole is opened at the lower end of the concave side of the steel profiles at both ends of the suction cup tooling, and each bolt hole is installed with a suction cup. A through hole is left in the web of the suction cup tooling for connecting the dovetail slider.

[0009] Preferably, the suction cup tooling is made of 304 stainless steel, with long-term reliability.

[0010] Preferably, the length L1 of the main structure of the suction cup tooling is 332 mm, the width W1 is 80 mm, and the height H1 is 60 mm;

[0011] The length L2 of the middle connecting plate of the main structure of the suction cup tooling is 192 mm, the width W1 is 10 mm, and the height H1 is 60 mm;

[0012] Each end of the main structure of the suction cup tooling is provided with a steel profile; the length L3 of each steel profile is 70 mm, the width W2 is 80 mm, the height H1 is 60 mm, and the thickness Z1 of the connecting plate is 10 mm; a groove is provided inside the steel profile, and the depth D1 of the groove along the length direction is 60 mm, the depth along the width direction is D2 is 60 mm, and the depth D3 along the height direction is 50 mm;

[0013] On both sides of the intermediate connecting plate of the main body structure, there is an M8 through-hole respectively. The distance T3 from the center of the hole to the edge of the connecting plate in the height direction is 30 mm, the distance T2 from the edge in the length direction is 56 mm, and the hole pitch T1 is 80 mm.

[0014] On the bottom plate of the steel groove at both ends of the main body structure, there is an M16 through-hole. The distance S1 from the center of the through-hole to the outer edge of the steel in the length direction is 30 mm, and the distance S2 from the edge in the width direction of the steel is 40 mm.

[0015] The intermediate connecting plate of the main body structure and the steel at both ends are connected by fillet weld A, and the leg size hf is 5 mm; the side plate and the bottom plate of the steel at both ends adopt a V-shaped groove and are connected by butt weld B.

[0016] Preferably, when the suction cup tooling uses a 2.5-mm indenter to detect the strength of ordinary glass, the indentation depth is 20 μm and the deformation is 0.87 μm; when using a 2.5-mm indenter to detect the strength of tempered glass, the indentation depth is 23 μm and the deformation is 1.02 μm; when using a 5-mm indenter to detect the strength of tempered glass, the indentation depth is 30 μm and the deformation is 1.33 μm; the deformation is less than 5% of the indentation depth. The suction cup tooling provides sufficient test stiffness for the equipment and ensures the accuracy of the test.

[0017] Preferably, the diameter of the suction cup is 160 mm.

[0018] Preferably, when the suction cup vertically detects the glass, the required adsorption force is 800 N and the actual safety adsorption force is 2000 N; when horizontally detecting the glass, the required adsorption force is 100 N and the actual safety adsorption force is 1600 N; the suction cup provides sufficient adsorption force for glass at different inclination angles and ensures the test stability of the device.

[0019] A detection method using the above-mentioned on-site detection rigid integral tooling detection device for glass mechanical properties includes the following steps:

[0020] Step 1: Fix the device and locate the measurement point

[0021] Fix the test equipment and the glass to be tested; during the test, manually control the displacement to roughly align the indenter with the center of the measurement point; then precisely adjust the position of the indenter through the rotating threads at both ends of the dovetail slider to ensure that it is on the same vertical line as the center of the test point, that is, align with the center of the point to be tested.

[0022] Step 2: Determine the key test parameters

[0023] Use a 2.5-mm diameter tungsten carbide spherical indenter to test the local strength of ordinary glass or the residual stress of tempered glass, and use a 5-mm diameter spherical indenter to test the local strength of tempered glass.

[0024] The radius of the initial annular crack needs to be obtained during the test process; when the initial annular crack of the glass appears under the action of a 2.5 mm indenter, the indentation depth is between 20 μm and 25 μm; when the initial annular crack of the glass appears under the action of a 5 mm indenter, the indentation depth is between 22 μm and 29 μm; before the formal test, select the minimum indentation depth within this range and gradually increase it until the initial annular crack appears.

[0025] Step 3: Test and determine the radius of the initial annular crack

[0026] Adopt the single - loading method. When the maximum indentation depth is reached, the loading stops and the unloading starts until the load is 0 kgf and the test stops; both the loading rate and the unloading rate are set to 0.01 mm / min.

[0027] Use an electronic digital magnifier to measure the radius of the initial annular crack that appears during the indentation test. Take the average value of 3 - 5 effective initial annular crack radii as the calculated value of the initial annular crack radius of the glass to be tested.

[0028] Step 4: Calculate the glass strength and residual stress

[0029] Substitute the calculated value of the initial annular crack radius of the glass to be tested into Equation (1) for calculation to obtain the local strength of the glass to be tested; measure the local strengths of tempered glass and ordinary glass, and then substitute them into Equation (2) to obtain the residual stress of the tempered glass.

[0030] The representative value of the test index is taken as the average value of the local strengths measured for 3 pieces of the same batch of glass at the same critical indentation depth, and the number of measurement points for each piece of glass is 3 - 5.

[0031]

[0032] In the formula, A c is the radius of the measured initial annular crack; R is the radius of the indenter; E * is the equivalent elastic modulus when the tungsten carbide indenter contacts the glass, which is a fixed value.

[0033] σ r = σ′0 - σ0 (2)

[0034] In the formula, σ′0 is the local strength of the tempered glass; σ0 is the local strength of the ordinary glass; σ r represents the average stress in the process zone, that is, the residual stress.

[0035] Preferably, in the on - site inspection rigid integral tooling inspection method for the mechanical properties of the glass, the indentation depth is gradually increased by 1 μm each time.

[0036] The beneficial effects of the present invention:

[0037] (1) The rigid integral tooling is stable and reliable. A stable and reliable sucker tooling structure is adopted, which has high rigidity and is not prone to deformation. Four suckers provide sufficient adsorption force between the sucker and the glass. Especially when facing the vertical glass detection, this set of rigid integral tooling can provide sufficient rigidity to ensure the accuracy of detection.

[0038] (2) Simplify manual operation. The sucker is pressurized by a vacuum pump, which does not rely on manual labor and is convenient for on-site detection. The portable mechanical property tester is directly connected to the computer to quickly analyze the detection results and obtain the results.

[0039] (3) The measuring point position can be adjusted flexibly. The portable mechanical property detector can move along the X and Y direction sliding guides on the dovetail slider, which is convenient for testing different positions of the glass after the tooling is fixed; there are scales marked on the dovetail slider, and the position of the indenter can be accurately adjusted through the rotating threads at both ends of the slider, with an accuracy of 0.1 mm, providing accurate positioning for the measuring point calibration.

[0040] (4) High detection efficiency. Select the indenter with appropriate size according to the strength or residual stress of the tested glass, and then confirm the indenter penetration depth parameter into the glass, which improves the testing efficiency.

[0041] (5) The test results are accurate and reliable. When the initial indentation depth is small, record the radius of the circular crack in the stable area through the electronic digital magnifier, and the strength and residual stress of the glass can be obtained by using the formula.

When the maximum penetration depth is reached, the loading stops and the unloading starts until the load reaches 0 kgf and the test stops; the loading rate and the unloading rate are both set to 0.01 mm / min; Use an electronic digital magnifier to measure the radius of the initial circular crack that appears during the indentation test, and take the average value of 3 - 5 effective initial circular crack radii as the calculated value of the initial circular crack radius of the glass to be tested; Step 4: Calculate the glass strength and residual stress Substitute the calculated value of the initial circular crack radius of the glass to be tested into Equation (1) for calculation to obtain the local strength of the glass to be tested; measure the local strength of tempered glass and ordinary glass, and substitute it into Equation (2) to obtain the residual stress of tempered glass; The representative value of the test index is taken as the average value of the local strengths measured for 3 pieces of the same batch of glass at the same critical penetration depth, and the number of measurement points for each piece of glass is 3 - 5; Where A c is the radius of the measured initial annular crack; R is the radius of the indenter; E * is the equivalent elastic modulus when the tungsten carbide indenter contacts the glass, which is a fixed value; σ r = σ′0 - σ0 (2) In the formula, σ′0 is the local strength of tempered glass; σ0 is the local strength of ordinary glass; σ r represents the average stress in the process zone, which is the residual stress.
