[0026] In the present solution, when a rectangular building surface to be tested is tested, the guide rail 1 and the support 2 are installed on one side of the building surface to be tested along the length direction of the building surface to be tested, so that a first gap is provided between the top of the first marking component 5 and the building surface to be tested, wherein the first gap is a deformation threshold value of the building surface to be tested that does not need to be repaired; then the support 2 is slid along the guide rail 1, so that the first marking component 5 moves linearly along the building surface to be tested, and when the deformation of the building surface to be tested exceeds the deformation threshold value, the first marking component 5 contacts the building surface to be tested and can leave a mark on the building surface to be tested, wherein the first marking component 5 can be a conventional technical means in the field such as a marking pen, which will not be described in detail here; in the field, the deformation of the building surface to be tested is generally a local arc-shaped convex surface, and when the first marking component 5 contacts the building surface to be tested, according to the curvature of the building surface to be tested, the first marking component 5 can be compressed to make the second The spring 501 is compressed to ensure that the first marking component 5 is always in contact with the deformation area of ​​the building surface to be tested that exceeds the deformation threshold, so that a linear mark is left at the deformation of the building surface to be tested, and the position of the guide rail 1 is adjusted along the width direction of the building surface to be tested, and the support 2 is slid along the guide rail 1 again, so as to comprehensively detect the rectangular building surface to be tested, and the deformation range of the surface to be tested can be intuitively detected according to the mark left on the surface to be tested; wherein, when the first marking component 5 is squeezed by the building surface to be tested, if the squeezing force is too large, the mounting rod 3 will move, so that the first spring 4 is compressed, and the mounting rod 3 is provided to ensure that the first marking component 5 only extends a shorter distance of the second slide groove 301, so that when the deformation is too large, the first marking component 5 can be prevented from breaking, and the range of axial movement of the first marking component 5 along the building surface to be tested is guaranteed, thereby ensuring the marking range.

[0027] In one embodiment of the present invention, a cavity 302 connected to the second slide groove 301 is provided in the mounting rod 3, and the cavity 302 is connected to the second slide groove 301 through a connecting hole 303, and the diameter of the connecting hole 303 is smaller than the diameter of the cavity 302 and the second slide groove 301. A sliding rod 304 is slidably installed in the cavity 302, and an extrusion plate 305 is fixedly connected to the end of the sliding rod 304 away from the second slide groove 301, and the end of the sliding rod 304 close to the second slide groove 301 extends into the connecting hole 303, and a third spring 306 sleeved on the sliding rod 304 is fixedly connected between the extrusion plate 305 and the top wall of the cavity 302, and a spring 306 that can extend To the push rod 502 in the connecting hole 303, when the first spring 4 is in a normal state, a gap is set between the push rod 502 and the sliding rod 304, and a plurality of through grooves 307 connected to the cavity 302 are circumferentially arranged on the mounting rod 3 with the axis of the mounting rod 3 as the center, and a plurality of card slots 202 corresponding to the through grooves 307 are set on the support 2, and a card block 308 that can extend into the card slot 202 is slidably installed in the through groove 307, and a trapezoidal block 309 is fixedly set at the end of the card block 308 extending to the cavity 302, and an inclined surface that matches the inclined edges of the plurality of trapezoidal blocks 309 is set on the extrusion plate 305, and a fourth spring 310 is fixedly connected between the trapezoidal block 309 and the support 2.

[0028] When the deformation height of the building surface to be measured is less than the maximum sliding displacement of the first marking component 5 in the second sliding groove 301, the block 308 is engaged in the slot 202. At this time, only the second spring 501 can be compressed and deformed. When the deformation height of the building surface to be measured exceeds the maximum sliding displacement of the first marking component 5 in the second sliding groove 301, the movement of the first marking component 5 drives the push rod 502 to move until the push rod 502 abuts against the slide bar 304, and drives the slide bar 304 and the extrusion plate 305 to move, so that the inclined surface of the extrusion plate 305 cooperates with the inclined edge of the trapezoidal block 309, thereby extruding the inclined edge of the trapezoidal block 309, so that the trapezoidal block 309 drives the block 308 to move radially along the installation rod 3 to disengage from the slot 202. At this time, the first marking component 5 moves downward and drives the installation rod 3 to move downward to improve the stability of the first marking component 5.

[0030] In this solution, the second marking component 6 can be a conventional technical means in the field such as a marking pen. When the support 2 moves along the guide rail 1, the second marking component 6 contacts the marking surface. If the deformation of the building surface to be measured does not exceed the deformation threshold, the mark of the second marking component 6 on the marking surface is a straight line. If the deformation of the building surface to be measured exceeds the deformation threshold, the first marking component 5 is moved to drive the second marking component 6 to move axially, so that the second marking component 6 can make corresponding marks on the marking surface of the guide rail 1 according to the deformation height of the building surface to be measured, so as to judge the deformation height of the building surface to be measured.

[0034] S2: Slide the support 2 along the guide rail 1 to make the first marking component 5 move linearly along the length direction of the building surface to be tested. When the deformation of the building surface to be tested exceeds the deformation threshold, the first marking component 5 contacts the building surface to be tested and leaves a mark on the building surface to be tested to identify the deformation range of the building surface to be tested, wherein the first marking component 5 drives the fixing rod 503 to move so that the second marking component 6 makes a mark on the marking surface of the guide rail 1 to identify the deformation height of the building surface to be tested; wherein, when the deformation height of the building surface to be tested is less than the first marking component 5 in the second slide groove 301, the second marking component 6 moves to the second slide groove 302. When the maximum displacement of the first marking component 5 is reached, the card block 308 is connected to the card slot 202. When the deformation height of the building surface to be measured exceeds the maximum displacement of the first marking component 5 in the second sliding slot 301, the first marking component 5 moves to drive the push rod 502 to move until the push rod 502 abuts against the slide bar 304, and drives the slide bar 304 and the extrusion plate 305 to move, so that the inclined surface of the extrusion plate 305 cooperates with the inclined edge of the trapezoidal block 309, thereby squeezing the inclined edge of the trapezoidal block 309 so that the trapezoidal block 309 drives the card block 308 to move radially along the installation rod 3 to disengage from the card slot 202.

[0035] S3: Adjust the position of the guide rail 1 along the width direction of the building surface to be tested, and repeat steps S1-S2 to complete the detection of the entire building surface to be tested.
