Description

Technical Field

[0001] The present invention belongs to the field of deformation measurement of low-rise shear walls, and particularly relates to a measuring device for shear deformation of low-rise shear walls. Background Art

[0002] Currently, in low-rise large-space buildings and nuclear island plants, due to their large bay and large depth, the shear walls used are generally low-rise shear walls. When studying the seismic performance of low-rise shear walls, the average shear displacement in the rectangular area of the shear wall is one of the main measurement data. Using a wire displacement meter and arranging it along the diagonal of the wall for measurement is the most commonly used method for measuring the shear deformation of low-rise shear walls at present.

[0003] The accuracy of the measuring device for shear deformation of low-rise shear walls and the measurement method determine the accuracy and correctness of the measured data of the wall shear deformation, and thus affect the accuracy of the test results. However, due to problems such as the insufficient accuracy of the commonly used measuring device in the test - the wire displacement meter, and the easy detachment of the wire displacement meter as the wall cracks develop during the test. The deformation data obtained by the current measuring device and method for shear deformation of low-rise shear walls often cannot meet the test requirements.

[0004] Therefore, by improving the measuring device and method for low-rise shear walls to address these problems, especially the systematic errors that are currently relatively common. It will improve the accuracy and correctness of the measured data and provide services for structural tests. Summary of the Invention

[0006] To achieve the above object, the technical solution adopted by the present invention is: A measuring device for shear deformation of low-rise shear walls includes a fixing component, a dial indicator, and a connecting wire. The fixing component is arranged at the four corners of the wall and fixedly connected to the wall. The connecting wire sequentially connects the fixing components located at the four corners of the wall through the dial indicator, and connects the fixing components located at the diagonals among the four corners through the dial indicator, so as to measure the shear deformation of the wall through the dial indicator.

[0007] Further, the fixing assembly includes fixing members, first connecting members and second connecting members. The number of the fixing members is four, and the four fixing members are respectively connected to the four corners of the wall. The number of the first connecting members is four, and dial indicators are arranged on all the four first connecting members. One end of the dial indicator located on the first connecting member is connected to the fixing member through the connecting line to form a rectangle. The number of the second connecting members is two, and dial indicators are arranged on both the two second connecting members. One end of the dial indicator located on the second connecting member is connected to the fixing member through the connecting line to form the diagonal of the rectangle.

[0008] Further, parallel connection holes and oblique connection holes are formed in the fixing member. The number of the parallel connection holes is two, and the two parallel connection holes are respectively located on both sides of the oblique connection hole.

Bolts are respectively passed through the first connection hole and the parallel connection hole and the second connection hole and the oblique connection hole to realize the connection between the first connecting member and the second connecting member and the fixing member.

[0009] Further, the number of the oblique connection holes is two, and the number of the second connection holes is also two. The two oblique connection holes respectively communicate with the two second connection holes.

[0010] Further, the size of the oblique connection hole is larger than that of the second connection hole.

Detailed Embodiments

[0022] The present invention will be further described below with reference to the drawings and specific embodiments.

[0023] As Figures 1-3 shown, a measuring device for the shear deformation of a low-rise shear wall provided by the present invention includes a fixing component 1, a dial indicator 2 and a connecting wire 3. The fixing component 1 is arranged at the four corners of the wall and fixedly connected to the wall. The connecting wire 3 is sequentially connected to the fixing components 1 located at the four corners of the wall through the dial indicator 3, and is connected to the fixing components 1 located diagonally among the four corners through the dial indicator 3 to measure the shear deformation of the wall through the dial indicator 3.

[0024] It can be understood that the connecting line 3 can be a wire, a rope, etc. When the wall undergoes shear deformation, the measuring needle of the dial indicator 2 is pulled by the connecting line 3 to displace, so that the shear deformation is displayed by the dial indicator 2.

[0025] It can be understood that the connection between the fixing component 1 and the wall can be any way such as bolt connection, clamping connection, pasting, etc., as long as the fixing component 1 can be fixedly connected to the wall.

[0026] Furthermore, the fixing component 1 includes fixing members 11, first connecting members 12 and second connecting members 13. The number of fixing members 11 is four, and the four fixing members 11 are respectively connected to the four corners of the wall. The number of first connecting members 12 is four, and dial indicators 2 are arranged on all four first connecting members 12. One end of the dial indicator 2 located on the first connecting member 12 is connected to the fixing member 11 through the connecting line 3 to form a rectangle. The number of second connecting members 13 is two, and dial indicators 2 are arranged on both second connecting members 13. One end of the dial indicator 2 located on the second connecting member 13 is connected to the fixing member 11 through the connecting line 3 to form the diagonal of the rectangle.

[0027] It can be understood that the four first connecting members 12 can be respectively connected to the four fixing members 11, or two first connecting members 12 can be connected to any one fixing member 11, and the other two first connecting members 12 are respectively connected to one fixing member 11, as long as the four fixing members 11 form a sequentially connected rectangle through the four first connecting members 12, the dial indicators 2 located on the first connecting members 12 and the connecting line 3.

[0028] Furthermore, parallel connection holes 111 and inclined connection holes 112 are formed on the fixing member 11. The number of parallel connection holes 111 is two, and the two parallel connection holes 111 are respectively located on both sides of the inclined connection hole 112. A first connection hole 121 is formed on the first connecting member 12, and the first connection hole 121 communicates with the parallel connection hole 111. A second connection hole 131 is formed on the second connecting member 13, and the second connection hole 131 communicates with the inclined connection hole 112, so as to connect the first connecting member 12 and the second connecting member 13 to the fixing member 11 by bolts passing through the first connection hole 121 and the parallel connection hole 111 and the second connection hole 131 and the inclined connection hole 112 respectively.

[0029] It can be understood that when the four first connecting members 12 are respectively connected to the four fixing members 11, the first connection hole 121 on each first connecting member 12 communicates with one parallel connection hole 111 on the fixing block 11. When two first connecting members 12 are connected to one fixing member 11, the first connection holes 121 of the two first connecting members 12 respectively communicate with the two parallel connection holes 111 on the fixing member 11, and the first connecting member 12 is connected to the fixing member 11 by bolts passing through the communicating first connection hole 121 and parallel connection hole 111.

[0030] Further, the number of the obliquely connecting holes 112 is two, and the number of the second connecting holes 131 is also two. The two obliquely connecting holes 112 are respectively communicated with the two second connecting holes 131.

[0031] It can be understood that by setting the number of the obliquely connecting holes 112 and the second connecting holes 131 to two, the stability of the connection between the second connecting member 13 and the fixing member 11 is increased, and relative rotation between the second connecting member 13 and the fixing member 11 is avoided after being fixed by bolts, so as to affect the measurement result.

[0032] Further, the size of the obliquely connecting hole 112 is larger than that of the second connecting hole 131, so that the second connecting hole 131 can move relative to the obliquely connecting hole 112 and then be fixed by bolts, thereby realizing the angle adjustment of the second connecting member 13.

[0033] Further, the fixing member 11 includes a fixing block 113 and a connecting plate 114. The fixing block 113 is connected to the wall body, the connecting plate 114 is connected to the fixing block 113, and the parallel connecting holes 111 and the obliquely connecting holes 112 are both formed in the connecting plate 114.

[0034] It can be understood that the fixing block 113 and the connecting plate 114 can be integrally formed, or can be connected by any means such as welding, clamping, threaded connection, etc.

[0035] Further, the first connecting member 12 includes a first connecting portion 122 and a first clamping portion 123. The first connecting hole 121 is formed at one end of the first connecting portion 122, the first clamping portion 123 is connected to the end of the first connecting portion 122 far from the first connecting hole 121, and the dial indicator 2 is clamped on the first connecting member 12 through the first clamping portion 123.

[0036] Further, the second connecting member 13 includes a second connecting portion 132 and a second clamping portion 133. The second connecting hole 131 is formed at one end of the second connecting portion 132, the second clamping portion 133 is connected to the end of the second connecting portion 132 far from the second connecting hole 131, and the dial indicator 2 is clamped on the second connecting member 13 through the second clamping portion 133.

[0037] It can be understood that in this embodiment, both the first clamping portion 123 and the second clamping portion 133 are annular, and the dial indicator 2 is clamped inside the ring to achieve clamping. In other embodiments, the first clamping portion 123 and the second clamping portion 13 can be of any structure as long as they can connect the dial indicator 2.

[0038] It can be understood that the first connecting portion 122 and the first clamping portion 123 and the second connecting portion 132 and the second clamping portion 133 are integrally formed.

[0039] Further, one end of the first connecting portion 122 where the first connecting hole 121 is opened is at a right angle, and one end of the second connecting portion 132 where the second connecting hole 131 is opened is rounded.

[0040] Further, the surface of the fixing block 113 close to the wall is roughened to increase the friction coefficient.

[0041] The present invention also provides a method for measuring the shear deformation of a low-rise shear wall, including the steps:

[0042] S1, assembling the fixing component;

[0043] Specifically, before the test measurement, first assemble the fixing component, that is, install the first connecting member and the second connecting member on the fixing member.

[0044] S2, installing the measuring part;

[0045] Specifically, install the dial indicator in the first connecting member and the second connecting member, and connect them in sequence through the connecting rope to form a rectangular and diagonal connection form.

[0046] In this embodiment, after installation, pull the connecting rope to drive the measuring rod of the dial indicator to make the reading of the dial indicator half of the full range.

[0047] S3, measuring the shear deformation of the low-rise shear wall;

[0048] Specifically, after installing the measuring part, read the value of the dial indicator, and compare the reading of the dial indicator with the initial reading to obtain the shear deformation of the low-rise shear wall.

[0049] Further, after step S3, there is also included the step:

[0050] S4, the test is over, and the device is disassembled.

[0051] It can be seen from the above embodiments that the present invention measures the deformation of the shear wall by fixing the dial indicator through the fixing component, improving the measurement accuracy. Using 6 measurement data of the rectangular sides and the diagonal to mutually verify the measurement results to ensure the correctness of the deformation measurement results. At the same time, it is relatively easy to implement engineering applications, improving the applicability of the improvement of the shear deformation measurement of the low-rise shear wall.
