[0004] The existing technical solution has the following defects: in the process of measuring the wall flatness by using the ruler, in order to ensure the accuracy of the wall flatness data, the plug ruler needs to be used to measure multiple points multiple times, which is complicated and low in efficiency. CONTENT OF THE UTILITY MODEL

[0005] The application provides a wall flatness measuring instrument for building construction, which can quickly and accurately measure the wall flatness.

[0006] The above technical purpose of the application is achieved by the following technical solution:

[0008] By adopting the above technical solution, the installation plate, the fixed plate, the partition plate and the measuring element are arranged, a plurality of measuring elements are arranged in the length direction of the installation plate, the sliding distance of the measuring element is used to read the wall flatness data when the measuring assembly measures the wall flatness, and the sliding of the plurality of measuring elements can accurately display the wall flatness under the length of the installation plate, which is convenient for comparison and recording, and the efficiency is higher than that of using the ruler and the plug ruler to repeatedly measure the flatness of different points.

[0009] Optionally, one end of the fixed plate is a protruding end located outside the installation plate, and the end face on the same side of the measuring element and the protruding end is processed to form a protruding arc surface.

[0010] By adopting the above technical solution, the protruding arc surface has a larger contact area with the wall when measuring the wall flatness, so that the measurement result is more accurate.

[0011] Optionally, the protruding arc surface is provided with an anti-skid pad.

[0018] By adopting the above technical scheme, the connecting groove and the connecting piece can connect two different measuring assemblies in the length direction to form a whole, and when the wall flatness of a long distance is measured, the measuring assemblies can be connected to measure the flatness at one time, thereby improving the measurement efficiency, and the separate measuring assemblies occupy less space and are convenient to transport.

[0020] By adopting the above technical solution, and by setting a locking plate, a hinge post, and a coil spring, when the connector is inserted into the connecting groove, the end face of the connector contacts and slides relative to the end face of the locking plate, compressing the coil spring until the end face of the connector abuts against the end face of the connecting groove. The end face of the locking plate then locks the connector in place, thus fixing the connector and reducing the possibility of separation of two different measuring components during the measurement process.

[0021] Optionally, the end face of the locking plate located in the connecting groove is machined to be chamfered.

[0022] By adopting the above technical solution, the chamfering makes it easier to rotate when connecting or disassembling two different measuring components, thus improving the efficiency of installation or disassembly.

[0023] In summary, this application has the following technical effects:

[0024] 1. By setting up an installation plate, a fixing plate, a partition plate, and measuring components, and by setting multiple measuring components along the length of the installation plate, the wall flatness data is read by the sliding distance of the measuring components when the measuring component measures the wall flatness. The simultaneous sliding of multiple measuring components can accurately display the wall flatness along the length of the installation plate, which is convenient for comparison and recording. At the same time, compared with using a straightedge and feeler gauge, it is more efficient to repeatedly measure the flatness at different points.

[0025] 2. By setting a protruding curved surface, the contact area with the wall is larger when measuring wall flatness, making the measurement results more accurate;

When facing long-distance wall flatness measurement, flatness measurement can be carried out at one time by connecting multiple measuring components, improving measurement efficiency. At the same time, individual measuring components occupy little space and are easy to transport. Attached Figure Description

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] This application discloses a wall flatness measuring instrument for building construction, referring to... Figure 1 and Figure 2 The measuring instrument includes a measuring component 1 and a connecting structure 2 mounted on the measuring component 1. The measuring component 1 can measure the flatness of the wall surface in the vertical or horizontal direction. Compared with using a straightedge and feeler gauge to measure the flatness data point by point, the measuring component 1 can display the flatness data over a distance at once, improving measurement efficiency. The connecting structure 2 allows multiple measuring components 1 to be combined in the length direction to meet the flatness measurement of a wall surface with a certain span. The independent measuring component 1 is convenient for transportation.

[0032] Combination Figure 1 and Figure 2 The measuring component 1 includes two parallel and spaced strip mounting plates 11. A fixing plate 12 is fixedly connected to the end of each of the two mounting plates 11. The fixing plate 12 is a strip plate with its surface perpendicular to the length direction of the mounting plates 11. The side wall of the fixing plate 12 is fixed to the opposite end of the two mounting plates 11. The length direction of the fixing plate 12 is perpendicular to the length direction of the mounting plates 11. The surface of the fixing plate 12 is flush with the end faces of the two mounting plates 11. One end face of the fixing plate 12 is a protruding end 121, and the protruding end 121 is located outside the mounting plates 11.

[0033] Combination Figure 1 and Figure 2 Multiple partition plates 13 are provided between two mounting plates 11. The surface of the partition plates 13 is perpendicular to the length direction of the mounting plates 11, and the sidewalls of the partition plates 13 are fixed to the opposite surfaces of the two mounting plates 11. The multiple partition plates 13 are evenly distributed between the two mounting plates 11, dividing the space between the two mounting plates 11 into individual mounting cavities 112. A measuring element 14 is slidably disposed in each mounting cavity 112. The measuring element 14 is a square column, and its length direction is parallel to the length direction of the fixed plate 12. The opposite sidewalls of the measuring element 14 slide against the opposite surfaces of the two mounting plates 11 within the mounting cavity 112. Both ends of the measuring element 14 are located outside the mounting plates 11, and the distance from the protruding end 121 to the sidewall of the adjacent mounting plate 11 is less than the distance from the end face of the measuring element 14 on the same side to the sidewall of the adjacent mounting plate 11.

[0034] Combination Figure 1 and Figure 2The end face of the measuring element 14, which is located on the same side of the mounting plate 11 as the protruding end 121, is processed into a protruding arc surface 141. When measuring the flatness of the wall surface, the protruding arc surface 141 has a larger contact area with the wall surface, making the measurement results more accurate. An anti-slip pad is provided on the protruding arc surface 141, which can reduce the possibility of the measuring instrument slipping during the measurement process.

[0035] Combination Figure 1 and Figure 2 Each mounting cavity 112 has two mounting plates 11 with strip-shaped sliding holes 111 on their surfaces. The sliding holes 111 connect the two surfaces of the mounting plates 11. The length direction of the sliding holes 111 is parallel to the length direction of the fixed plate 12. A sliding plate 143 is provided on the side wall where the measuring element 14 slides against the mounting plate 11. The surface of the sliding plate 143 is perpendicular to the length direction of the measuring element 14. The sliding plate 143 is adapted to the sliding hole 111 and is slidably disposed in the sliding hole 111. The sliding plate 143 is away from the protruding arc surface 141. A tension spring 15 is provided in the sliding hole 111. One end of the tension spring 15 is fixedly connected to the surface of the sliding plate 143, and the other end is fixedly connected to the end wall of the sliding hole 111. The tension spring 15 is located on the side of the sliding plate 143 closer to the protruding arc surface 141. The tension spring 15 can reset the measuring element 14 after the measuring instrument finishes measuring, which is convenient for the next measurement.

[0036] Combination Figure 1 and Figure 2 The measuring component 14 is provided with a scale 142 on the side wall where it slides and fits against the mounting plate 11. The flatness data of the wall surface can be observed by using the side wall of the mounting plate 11 as a reference. When the protruding arc surface 141 is flush with the end face of the fixing plate 12, the scale 142 returns to zero.

[0037] Combination Figure 1 and Figure 2 The connecting structure 2 includes a connector 21 disposed on the surface of a fixed plate 12 at one end of the measuring component 1 along its length. The connector 21 is away from the measuring component 14, and its length is parallel to that of the fixed plate 12.

A connecting groove 22 is provided on the end face of the fixed plate 12 at the other end of the measuring component 1 along its length. The opening of the connecting groove 22 is away from the protruding end 121, and the connecting groove 22 communicates with the surface of the fixed plate 12 away from the measuring component 14. The connecting groove 22 is adapted to the connector 21, and the connector 21 can be inserted into the connecting groove 22, thereby combining the two measuring components 1 along their length.

[0038] Combination Figure 1 and Figure 2The end face of the fixing plate 12 away from the protruding end 121 is provided with fixing holes 23 at intervals from the connecting groove 22. The fixing holes 23 and the connecting groove 22 are connected to form a connecting notch 24. A strip-shaped locking plate 25 is rotatably installed in the connecting notch 24 and the fixing holes 23. A hinge post 26 is fixedly connected to the side wall of the locking plate 25. The axis of the hinge post 26 is perpendicular to the side wall of the locking plate 25 and perpendicular to the length direction of the fixing plate 12. The end of the hinge post 26 away from the locking plate 25 is rotatably embedded in the wall of the fixing hole 23. One end of the locking plate 25 protrudes from the connecting notch 24 and is located in the connecting groove 22, and the other end is located outside the end face of the fixing plate 12.

[0039] Combination Figure 1 and Figure 2 A coil spring 27 is fitted around the periphery of the hinge post 26. One end of the coil spring 27 is fixed to the side wall of the locking plate 25, and the other end is fixed to the wall of the fixing hole 23. When the connector 21 is inserted into the connecting groove 22, the end face of the connector 21 contacts and slides relative to the end face of the locking plate 25, compressing the coil spring 27 until the end face of the connector 21 abuts against the end face of the connecting groove 22. The end face of the locking plate 25 then locks the connector 21 in place, thus fixing the connector 21. The end face of the locking plate 25 located in the connecting groove 22 is chamfered to facilitate sliding.
