[0002] At present, after the construction of the wall of a civil engineering project is completed, in order to ensure the construction quality, it is necessary to test the flatness of the wall.

[0003] In the prior art, the detection of wall flatness is mostly achieved by relying on a straightedge and a feeler gauge. That is, by attaching the straightedge to the side wall of the wall and then inserting the feeler gauge into the gap between the straightedge and the wall side wall to determine whether the wall flatness meets the requirements. This wall flatness detection method is relatively traditional. Since the feeler gauge has a relatively limited width and a long length, it is necessary to move the feeler gauge along the length direction of the straightedge multiple times to fully detect the wall area covered by the straightedge, which makes the entire wall flatness detection process relatively cumbersome and is not conducive to improving detection efficiency.

DETAILED DESCRIPTION

[0015] The technical solution of the present invention will be further described in detail below in conjunction with specific implementation methods.

[0016] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0017] See also Figure 1 、 Figure 2 as well as Figure 3 This embodiment provides a wall flatness detection device for civil engineering, including a box body 10, a release assembly 20, an elastic support assembly 30, a roller 40 and a marking assembly 50. A notch 102 is opened on one side of the box body 10 along the length direction. The roller 40 is arranged inside the box body 10, and a portion of the roller 40 extends into the notch 102. The elastic support assembly 30 is movably mounted on the inner wall of the box body 10 to provide elastic support for the roller 40. The release assembly 20 is provided in two groups, and the two groups of release assemblies 20 are installed in the box body 10 away from the notch 10 2, and the two groups of release components 20 are respectively located at opposite ends of the box body 10. When the box body 10 is placed on the wall and kept vertical, the two groups of release components 20 are used to release the elastic support component 30, so that the elastic support component 30 and the roller 40 can move from top to bottom along the inside of the box body 10 by virtue of their own gravity. The marking component 50 is arranged inside the box body 10. When the roller 40 moves to an uneven position of the wall and causes the elastic support component 30 to deform, the marking component 50 is used to mark the uneven position of the wall.

[0018] Initially, the elastic support assembly 30 and the roller 40 are located at one end of the box body 10 as a whole. When the wall flatness needs to be tested, the box body 10 can be placed at a certain position on the wall and the box body 10 is distributed vertically, and at the same time, the end of the box body 10 with the elastic support assembly 30 and the roller 40 is facing upwards. Then the staff controls a set of release assemblies 20 located at the bottom of the side wall of the box body 10, and uses the set of release assemblies 20 to release the elastic support assembly 30 and the roller 40. After the elastic support assembly 30 and the roller 40 are released, they move from top to bottom along the inside of the box body 10. When the elastic support assembly 30 and the roller 40 move to the other end of the inside of the box body 10, the staff turns the box body 10 180° and places the box body 10 again at another position on the wall. The support assembly 30 and the roller 40 can be located at the upper end position inside the box body 10 again, and then the staff can release the elastic support assembly 30 and the roller 40 again with the help of the release assembly 20 located below, so that the elastic support assembly 30 and the roller 40 can move from top to bottom along the inside of the box body 10 again; in the process of moving from top to bottom along the inside of the box body 10 after the above-mentioned elastic support assembly 30 and the roller 40 are released, the elastic support assembly 30 always provides elastic support for the roller 40, so the roller 40 can roll downward along the side wall of the wall through the slot 102. When the roller 40 rolls to an uneven position on the wall, it can drive the elastic support assembly 30 to deform, and at the same time use the marking assembly 50 to mark the uneven position so that the staff can intuitively understand the specific uneven position.

[0019] See also Figure 1 as well as Figure 3 In one embodiment, a guide rail 101 is fixedly provided on the inner wall of the box body 10 along the length direction, and the elastic support assembly 30 includes a slider 301, a second elastic member 302, a support rod 303 and a U-shaped bracket plate 306. The roller 40 is rotatably arranged on the inner side of the U-shaped bracket plate 306, and the slider 301 slides with the guide rail 101. One end of the support rod 303 is connected to the slider 301, and the other end passes through the U-shaped bracket plate 306 and movably cooperates with the U-shaped bracket plate 306. One end of the second elastic member 302 is connected to the slider 301, and the other end is connected to the U-shaped bracket plate 306, for providing elastic support to the U-shaped bracket plate 306.

[0020] After the box body 10 is placed on the wall and maintained in a vertical distribution, the slider 301 is released by a set of release components 20 located below, so that the slider 301 can slide downward along the guide rail 101, thereby driving the support rod 303, the U-shaped bracket plate 306 and the roller 40 to move downward along the inside of the box body 10 as a whole. During the movement, the roller 40 rolls downward along the side wall of the wall. When the roller 40 rolls to an uneven position, the U-shaped bracket plate 306 can move adaptively compared to the support rod 303, thereby causing the second elastic member 302 to expand and contract. At this time, the marking component 50 is used to mark the uneven position of the wall.

[0021] See also Figure 3 In one embodiment, the support rod 303 is located on the inner side of the U-shaped bracket plate 306 and is fixed with a first push block 304 and a second push block 305. The first push block 304 and the second push block 305 are respectively located on opposite sides of the support rod 303, and the first push block 304 and the second push block 305 are staggered along the length direction of the support rod 303. The roller 40 is provided with an annular groove 401 on the circumferential side wall. The marking assembly 50 includes a rotating shaft 501, an arc rod 502 and a marking pen 503. , there are two groups of the arc rods 502 and the marking pens 503, and the lines that can be drawn by the two groups of marking pens 503 are different in color. The two groups of marking pens 503 are arranged on the inner side of the annular groove 401, and one end of the two groups of arc rods 502 is respectively connected to one group of marking pens 503, and the other ends extend from the opposite sides of the roller 40 to the position between the first push block 304 and the second push block 305. The side walls of the two groups of arc rods 502 are rotatably connected to the U-shaped bracket plate 306 through a group of rotating shafts 501.

[0022] When the roller 40 rolls to the concave position, the second elastic member 302 can push the U-shaped bracket plate 306 so that the U-shaped bracket plate 306 moves. 06 Compared with the reverse movement of the support rod 303, which in turn drives the roller 40 to move in the reverse direction, the U-shaped bracket plate 306 drives the two groups of arc rods 502 and the two groups of marking pens 503 to move in the reverse direction synchronously when moving in the reverse direction, and one side of the other group of arc rods 501 can act on the second push rod 305 when moving in the reverse direction, and then be pushed by the second push rod 305. Compared with the rotation of the corresponding rotating shaft 501, the other group of arc rods 502 drives the corresponding marking pen 501 to move toward the outside of the annular groove 401 when rotating, and then draws a line at the recessed position to make a mark; since the lines that can be drawn by the two groups of marking pens 503 are different in color, the staff can judge whether the current uneven position is convex or concave according to the specific color of the lines on the wall, which is conducive to quickly formulating subsequent wall repair plans.

[0023] See also Figure 4 In one embodiment, an air passage 1012 is opened inside the guide rail 101, and a group of limiting air bags 1011 are respectively provided at both ends of the guide rail 101 away from the box body 10. The two groups of limiting air bags 1011 are respectively communicated with the air passage 1012. The two groups of release components 20 have the same structure and both include a first elastic member 202, a handle 203, a piston rod 204 and a tube body 205. The tube body 205 is fixedly arranged on the side wall of the box body 10 and communicated with the air passage 1012. One end of the piston rod 204 is connected to the handle 203, and the other end extends into the interior of the tube body 205 and is telescopically matched with the tube body 205. The first elastic member 202 is arranged on the side of the handle 203 away from the piston rod 204, for providing elastic support for the handle 203.

[0024] After the box body 10 is placed on the wall and maintained in a vertical distribution, the two groups of limiting air bags 1011 are in an expanded state, and the slider 301 is located at the upper end of the guide rail 101. The limiting air bag 1011 at the upper end of one side of the guide rail 101 acts on the inner wall of the slider 301 to expand the slider 301, thereby limiting the slider 301 so that the roller 40 is located at the upper inner part of the box body 10. At this time, the staff can pull the handle 203 corresponding to the release assembly 20 located below, thereby driving the corresponding piston rod 204 to move toward the outside of the corresponding tube body 205, thereby extracting the air inside the two groups of limiting air bags 1011 into the corresponding tube body 205 through the air channel 1012, causing the two groups of air bags 1011 to collapse. When the limiting air bag 1011 located above collapses, the expansion state of the slider 301 can be released, and the slider 301 is affected by gravity and moves along the guide rail 101 to When the slider 301 slides to the lower end of the guide rail 101, the staff releases the pulled handle 203, and drives the handle 203 close to the box body 10 under the elastic support of the first elastic member 202, thereby driving the corresponding piston rod 204 to move toward the inside of the corresponding tube body 205, so as to press the air inside the tube body 205 into the two sets of limiting air bags 1011 through the air channel 1012, so that the two sets of limiting air bags 1011 are re-inflated. At this time, the limiting air bag 1011 at the lower end of one side of the guide rail 101 acts on the inner wall of the slider 301 and then expands the slider 301 again, thereby limiting the slider 301, the U-shaped bracket plate 306 and the roller 40 again.

[0025] See also Figure 4 In one embodiment, the release assembly 20 further includes a holding frame 201, which is fixedly mounted on the outer wall of the box body 10. The tube 205, the piston rod 204, and the handle 203 are all disposed on the inner side of the holding frame 201. One end of the first elastic member 202 is connected to the handle 203, and the other end is connected to the inner wall of the holding frame 201.

[0026] When performing a wall flatness test, the staff can alternately hold the holding frames 201 corresponding to the two sets of release components 20, and then press the box body 10 against the side wall of the wall. While holding the holding frame 201, the staff can pull the handle 203 to drive the piston rod 204 to move toward the outside of the tube body 205 to release the slider 301, the U-shaped bracket plate 306 and the roller 40, so that the roller 40 can roll down along the side wall of the wall, thereby completing the wall flatness test.

[0027] In one embodiment, the first elastic member 202 and the second elastic member 302 may be springs or metal springs, which are not limited herein.

[0028] In the embodiment of the present invention, initially, the elastic support assembly 30 and the roller 40 are entirely located at one end of the interior of the box body 10. When it is necessary to detect the flatness of the wall, the box body 10 can be placed at a certain position on the wall so that the box body 10 is distributed vertically, and at the same time, the end of the box body 10 with the elastic support assembly 30 and the roller 40 is facing upward. Then, the staff controls a set of release assemblies 20 located at the lower side wall of the box body 10, and uses the set of release assemblies 20 to release the elastic support assembly 30 and the roller 40. After being released, the elastic support assembly 30 and the roller 40 move from top to bottom along the interior of the box body 10. When the elastic support assembly 30 and the roller 40 move to the other end of the interior of the box body 10, the staff turns the box body 10 180° and places the box body 10 again at another position on the wall. At this time, the elastic support assembly 30 and the roller 40 can be located at the upper end position of the interior of the box body 10 again. Then the staff again uses the release component 20 located at the bottom to release the elastic support component 30 and the roller 40, so that the elastic support component 30 and the roller 40 move from top to bottom along the inside of the box body 10 again; in the process of moving from top to bottom along the inside of the box body 10 after the above-mentioned elastic support component 30 and the roller 40 are released, the elastic support component 30 always provides elastic support for the roller 40, so the roller 40 can roll downward along the side wall of the wall through the slot 102. When the roller 40 rolls to an uneven position on the wall, the elastic support component 30 can be driven to deform, and the marking component 50 is used to mark the uneven position so that the staff can intuitively understand the specific uneven position. Compared with the existing technology, it can realize automatic detection of wall flatness, and can also automatically mark the detected uneven position, which has the advantages of easy operation and high detection efficiency.

[0029] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in this field without departing from the purpose of the present invention.
