Therefore, in building engineering, it is necessary to detect the wall thickness to ensure the quality and safety of the building. The mainstream detection methods include: direct measurement method, ultrasonic detection method, electromagnetic wave detection method, steel bullet impact method, optical measurement method, etc.

[0003] In building engineering, since most of the building wall surfaces are uneven, the direct measurement method and the electromagnetic wave detection method are more commonly used. Due to the low accuracy of the electromagnetic wave detection method, in actual operation in building engineering, the direct measurement method is still used, that is, tools such as a scale and a tape measure are used to measure the wall thickness one by one.

[0004] When directly measuring with a scale and a tape measure, when facing the walls at some indoor doors and windows, since there are mostly corner walls at the doors and windows, affected by the occlusion of the corner walls, it is mostly impossible to directly measure the wall thickness.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Refer to Figures 1-9 , a wall thickness detection device for building engineering quality supervision. In order to be able to directly measure the thickness of the wall at the doors and windows in the building and the connected corner walls, while reducing the number of measurements and reducing errors, a basic scale main body is set here. The basic scale main body includes a pad rack 1 and a first scale 2. The pad rack 1 is a horizontal frame body, and the first scale 2 is arranged in contact with the outer wall of the pad rack 1;

[0035] Measurement mechanism, the measurement mechanism includes a guide component 3 and an outer wall measurement component 4. The guide component 3 is arranged on the frame body of the pad rack 1, and the outer wall measurement component 4 is fixedly connected to the guide end of the guide component 3, so that the outer wall measurement component 4 can move along the frame body of the pad rack 1;

[0036] Corner wall rear positioning mechanism, the corner wall rear positioning mechanism includes an inner wall positioning frame 5 and a corner wall surrounding mechanism 6. The inner wall positioning frame 5 includes a starting frame 51 and a scale flush pad 52. The starting frame 51 is arranged on one side of the pad rack 1, and the connection part between the starting frame 51 and the pad rack 1 is located at the zero scale position of the first scale 2. The outer wall measurement component 4 is facing the starting frame 51;

[0037] The corner wall surrounding mechanism 6 includes an extended fitting frame 61 and a corner wall surrounding component 62. One end of the extended fitting frame 61 is connected to the end of the starting frame 51 away from the first scale 2, and the extended fitting frame 61 is parallel to the starting frame 51. A scale alignment pad 52 is arranged at the end of the extended fitting frame 61, and the scale alignment pad 52 and the zero scale of the first scale 2 are in the same vertical plane. The corner wall surrounding component 62 is arranged between the starting frame 51 and the extended fitting frame 61, and the corner wall surrounding component 62 and the extended fitting frame 61 can be extended synchronously. The corner wall surrounding component 62 and the extended fitting frame 61 can be adjusted for extension according to the thickness of the corner wall, so that the extended fitting frame 61 surrounds the outside of the corner wall, and the scale alignment pad 52 at the end of the extended fitting frame 61 presses against the inner wall of the wall to be measured, making the zero scale of the first scale 2 and the inner wall of the wall to be measured in the same plane. The corner wall surrounding component 62 fits and surrounds the outside of the corner wall. At this time, after the outer wall measuring component 4 moves on the guiding component 3 and fits against the outer wall of the wall to be measured, the outer wall measuring component 4 reads the value on the first scale 2.

[0038] The extended fitting frame 61 includes a movable insertion frame 611 and a connecting spring 612. Both the starting frame 51 and the movable insertion frame 611 are L-shaped frames, and the end of the frame body of the movable insertion frame 611 is movably inserted into the end of the starting frame 51. The connecting spring 612 is arranged at the movable connection between the movable insertion frame 611 and the starting frame 51.

[0039] Among them, the end of the frame body of the movable insertion frame 611 is a round shaft insertion rod, and the round shaft insertion rod is movably inserted into the end of the starting frame 51. The connecting spring 612 is arranged around the round shaft insertion rod, and both ends of the connecting spring 612 are respectively connected to the end of the frame body of the movable insertion frame 611 and the end of the starting frame 51. The scale alignment pad 52 is arranged at the end of the movable insertion frame 611. When pulling the movable insertion frame 611 away from the starting frame 51 to adapt to the thickness of the corner wall, the connecting spring 612 can be extended, and when releasing the movable insertion frame 611, the movable insertion frame 611 is pulled back to its original position by the pulling force of the connecting spring 612, which is convenient for the movable insertion frame 611 and the starting frame 51 to respectively fit against the inner and outer walls of the corner wall. As Figure 9 shown, at this time, the plane where the scale alignment pad 52 fits against the inner wall of the corner wall and the zero scale of the first scale 2 are in the same vertical plane, thus determining the zero scale point when measuring the thickness of the wall to be measured.

[0040] The starting frame 51 and the movable insertion frame 611 are in a group of two, and two groups are arranged in parallel on the upper and lower sides of one end of the cushion frame 1. The corner wall surrounding component 62 is located between the two groups of parallel starting frames 51 and movable insertion frames 611. The corner wall surrounding component 62 located between the two groups of starting frames 51 and movable insertion frames 611 is protected by the starting frame 51 and the movable insertion frame 611.

[0041] The corner wall surrounding assembly 62 includes a positioning base rod 621, a tension spring 622, an extension assembly 7, and a second scale 623. Two positioning base rods 621 are arranged in parallel as a group. One is arranged at the end of the cushion rack 1, and the other is arranged on the scale-flush cushion block 52. The extension assembly 7 is slidably mounted on the two positioning base rods 621. The tension spring 622 is arranged around the outside of the positioning base rod 621, and the tension spring 622 acts on the extension assembly 7 to keep the extension assembly 7 tending to move towards the cushion rack 1. The second scale 623 is arranged on the extension assembly 7. When inserting the starting rack 51 and the movable insertion rack 611 into the outside of the corner wall, the corner wall will squeeze the extension assembly 7 to move. At this time, the extension assembly 7 moves on the positioning base rod 621 and pulls the tension spring 622 to stretch, enabling the extension assembly 7 to fit the cross-sectional side wall of the corner wall.

[0042] The extension assembly 7 includes a fixed rack 71, a movable rack 72, and an extension spring 73. The fixed rack 71 is sleeved on one positioning base rod 621, the movable rack 72 is sleeved on the other positioning base rod 621, and one side of the movable rack 72 is movably inserted into the fixed rack 71 through a shaft body. The extension spring 73 is arranged between the fixed rack 71 and the movable rack 72, and the extension spring 73 is arranged around the outside of the shaft body of the movable rack 72. The movable rack 72 moves synchronously with the scale-flush cushion block 52 and the movable insertion rack 611. At this time, the extension spring 73 will also stretch, so that the length of the entire extension assembly 7 increases to adapt to the cross-sectional width of the corner wall.

[0043] Among them, as Figure 9 shown, the second scale 623 is fixedly arranged at the lower end of the fixed rack 71, and the zero scale of the second scale 623 is in the same vertical plane as the inner wall of the fixed rack 71. The movable rack 72 fits the top surface of the second scale 623, and the frame body of the movable rack 72 is in the same vertical plane as the scale-flush cushion block 52. When the movable rack 72 extends on the second scale 623, when the movable rack 72 fits the inner wall of the corner wall, the inner wall of the fixed rack 71 fits the outer wall of the corner wall. The thickness of the corner wall can be obtained through the reading of the movable rack 72 on the second scale 623.

[0044] As Figure 9 shown, both the fixed rack 71 and the movable rack 72 are right-angle racks. When the fixed rack 71 and the movable rack 72 extend and fit on the outside of the corner wall, the right-angle parts of the fixed rack 71 and the movable rack 72 will completely fit the corner of the corner wall, realizing a detailed fit to the corner of the corner wall, and it is more convenient to read through the second scale 623. In addition, as Figure 9 shown, if the side wall part of the cross-section of the corner wall is uneven, since both the fixed rack 71 and the movable rack 72 are right-angle fitted to the inner and outer walls of the corner wall and the reading is carried out through the second scale 623 on the fixed rack 71, the influence caused by the unevenness of the cross-section part of the corner wall can be avoided.

[0045] The guiding component 3 includes a guiding groove 31, a guiding rod 32 and a movable block 33. The guiding groove 31 is formed along the frame body of the cushion rack 1. The guiding rod 32 is arranged inside the guiding groove 31. The movable block 33 is movably arranged in the guiding groove 31, and the guiding rod 32 penetrates through the movable block 33. The outer wall measuring component 4 is arranged on the movable block 33, so that the outer wall measuring component 4 can slide in the guiding groove 31 along with the movable block 33, and is used to control the outer wall measuring component 4 to be away from the zero scale of the first scale 2. Thus, when the outer wall measuring component 4 is attached to the outer side of the wall, the edge of the outer wall measuring component 4 can be directly opposite to the scale on the first scale 2, and the thickness reading can be obtained intuitively.

[0046] The outer wall measuring component 4 includes a penetrating slide carriage 41 and an elastic extrusion member 42. The penetrating slide carriage 41 is movably inserted on the movable block 33, and the penetrating slide carriage 41 vertically penetrates through the guiding groove 31. The elastic extrusion member 42 is arranged between the penetrating slide carriage 41 and the movable block 33. In the normal state, the end of the penetrating slide carriage 41 does not penetrate through the guiding groove 31, which facilitates the sliding of the penetrating slide carriage 41 and the movable block 33 in the guiding groove 31. When it is necessary to use the penetrating slide carriage 41 to attach to the outer wall of the wall to be measured, the penetrating slide carriage 41 can be pushed to penetrate through the movable block 33 and the guiding groove 31. At this time, the frame body of the penetrating slide carriage 41 passing through the guiding groove 31 is attached to the wall on the other side of the cushion rack 1, so as to facilitate the penetrating slide carriage 41 to point to the first scale 2 and complete the reading.

[0047] The elastic extrusion member 42 includes a positioning rod 421 and an extrusion spring 422. The positioning rod 421 is horizontally arranged on the movable block 33. The penetrating slide carriage 41 is slidably arranged on the positioning rod 421, and the end of the penetrating slide carriage 41 penetrates through the movable block 33 and the guiding groove 31. The extrusion spring 422 is arranged around the outer side of the positioning rod 421, and one end of the extrusion spring 422 is connected to the movable block 33, and the other end is connected to the penetrating slide carriage 41, so that the penetrating slide carriage 41 keeps a tendency to be away from the movable block 33. After the reading is completed, under the elastic force of the extrusion spring 422, the penetrating slide carriage 41 is driven to reset.

[0048] Working principle: Pull the movable insert frame 611 on the starting frame 51 away from the starting frame 51. At this time, the connecting spring 612 stretches, and the movable frame 72 will move away from the fixed frame 71 synchronously with the movable insert frame 611. At this time, the extension spring 73 will also stretch. When the distance between the movable frame 72 and the fixed frame 71 is appropriate, the movable frame 72 and the fixed frame 71 can be inserted into the inner and outer sides of the corner wall. At this time, release the movable insert frame 611. Under the double pull of the connecting spring 612 and the extension spring 73, the movable frame 72 fits against the inner wall of the corner wall, and the fixed frame 71 fits against the outer wall of the corner wall. Then push the starting frame 51 and the movable insert frame 611 to make the scale leveling pad 52 at the end of the movable insert frame 611 abut against the corner of the wall to be measured and the corner wall. After completion, the pad frame 1 will fit against the outer wall of the corner wall. At this time, the first scale 2 fits against the outer wall of the corner wall. Since the zero scale of the first scale 2 and the scale leveling pad 52 are in the same plane, the zero scale of the first scale 2 and the inner wall of the wall to be measured are in the same plane. Pull the movable block 33 to slide in the guide groove 31 of the pad frame 1 and let the through carriage 41 slide to the outer wall of the wall to be measured. Then push the through carriage 41 to make the through carriage 41 pass through the guide groove 31 and abut against the outer wall of the wall to be measured. At this time, the thickness of the wall to be measured can be determined by the reading of the through carriage 41 on the first scale 2, and the thickness of the wall to be measured can be obtained intuitively. In addition, since the zero scale of the second scale 623 and the inner wall of the fixed frame 71 are in the same vertical plane, and the fixed frame 71 fits against the outer wall of the corner wall, the zero scale of the second scale 623 fits against the outer wall surface of the corner wall. The movable frame 72 fits against the inner wall of the corner wall, and the frame body of the movable frame 72 and the scale leveling pad 52 are also in the same vertical plane. At this time, the thickness of the corner wall can be determined by reading the reading of the movable frame 72 on the second scale 623, and the thickness of the corner wall can be obtained intuitively. Therefore, there is no need to calculate the wall thickness by measuring the values at multiple positions such as the wall and the corner wall, reducing the complexity of the operation process and reducing errors.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention.
