The purpose of house structure design is to ensure that the constructed structure is safe and applicable, can meet the requirements of various expected functions within the specified period of time, and is economical and reasonable.

[0003] When a house is being built, it is necessary to measure the flatness of the wall surface to ensure that the wall surface is flat after construction. After measuring the flatness of the wall surface with a measuring device, the device needs to be moved to measure other areas. When the measuring device is moved, it is easy for the device to collide with the wall surface, causing damage to the wall surface. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Example 1

[0023] Reference Figure 1-3 , a construction measurement device, comprising a fixing bar 1, wherein:

[0024] Two parallel connecting columns 2 are connected to one side of the fixed bar 1, and one end of each connecting column 2 is connected to a moving wheel 3. Two parallel movable frames 4 are slidably connected to the fixed bar 1, and each movable frame 4 is connected to a laser rangefinder 5. A display 6 is fixedly connected to the fixed bar 1, and a support rod 7 is fixedly connected to the bottom end of the fixed bar 1, and a bottom plate 8 is fixedly connected to the bottom end of the support rod 7. Two symmetrically arranged protective covers 9 are fixedly connected to the fixed bar 1, and each protective cover 9 cooperates with a different laser rangefinder 5.

[0025] Working process: when measuring the flatness of the wall surface, the connecting column 2 contacts the wall surface through the moving wheel 3, and the movable frame 4 is moved. The movable frame 4 drives the laser rangefinder 5 to move, so that the laser rangefinder 5 is separated from the protective cover 9. The two laser rangefinders 5 measure respectively, and the measured data are transmitted to the display 6. The measured data can be clearly known, and the flatness of the wall surface can be judged by the difference of the measured data. When the measuring position of the wall is changed by the moving device of the fixed bar 1, the moving wheel 3 rolls after contacting the wall, and the connecting column 2 rolls with the wall through the moving wheel 3. There will be no collision between the connecting column 2 and the wall, so that the wall surface will not be damaged;

[0026] When measuring a high part of a wall, the device is pushed upward by the support rod 7 to measure the high wall. After the measurement, the movable frame 4 is moved, and the movable frame 4 drives the laser rangefinder 5 to move, so that the laser rangefinder 5 moves to be located in the protective cover 9, and the protective cover 9 protects the laser rangefinder 5.

[0027] Example 2

[0028] After the movable frame 4 drives the laser rangefinder 5 to move, after the laser rangefinder 5 moves to the set position, due to the lack of fixation, the movable frame 4 slides to change the position of the laser rangefinder 5, referring to Figure 2As another preferred embodiment of the utility model, the difference from the embodiment 1 is that the movable frame 4 includes a movable sleeve 41, the movable sleeve 41 can be slidably sleeved on the fixed bar 1, the movable sleeve 41 is fixedly connected to the laser rangefinder 5, the upper end of the movable sleeve 41 is provided with a through hole, the through hole is plugged with a limit pin 42, the limit pin 42 is in contact with the fixed bar 1, the upper end of the movable sleeve 41 is fixedly connected with a spring 43, one end of the spring 43 is fixedly connected to the limit pin 42, the spring 43 is located on the outside of the limit pin 42, and the movable sleeve 41 is fixedly connected to the fixed bar 1. When moving, the limit pin 42 is pulled upward, and the limit pin 42 is separated from the fixed bar 1. At the same time, the limit pin 42 moves upward and pulls the spring 43. The spring 43 generates elastic force after being pulled. After the limit pin 42 is separated from the fixed bar 1, it pushes the movable sleeve 41 to move. The movable sleeve 41 drives the laser rangefinder 5 to move and changes the position of the laser rangefinder 5. After the position of the laser rangefinder 5 is determined, the limit pin 42 is released. Under the action of the elastic force of the spring 43, the limit pin 42 is driven to squeeze the fixed bar 1, so that the movable sleeve 41 does not slide.

[0029] Example 3

[0030] After the moving wheel 3 contacts the wall, the paint on the wall easily adheres to the moving wheel 3, changing the stability of the moving wheel 3 after contacting the wall, making the two laser rangefinders 5 not in the same plane, thereby reducing the measurement accuracy. Figure 3-4 As another preferred embodiment of the utility model, on the basis of embodiment 1, an anti-sticking mechanism 10 is connected to the moving wheel 3, and the anti-sticking mechanism 10 includes a connecting rod 101, one end of the connecting rod 101 is fixedly connected to the base of the moving wheel 3, and the other end of the connecting rod 101 is fixedly connected to a fixed seat 102, and a wiping block 103 is detachably connected to the fixed seat 102, and the wiping block 103 is in contact with the moving wheel 3. The wiping block 103 is a sponge block. The connecting rod 101 is connected to the fixed seat 102, and the fixed seat 102 fixes the wiping block 103 so that the wiping block 103 is in contact with the moving wheel 3. After the moving wheel 3 rolls, relative sliding occurs between the moving wheel 3 and the wiping block 103, and the wiping block 103 cleans the moving wheel 3, so that the powder is separated from the moving wheel 3, so that the two laser rangefinders 5 are in the same plane, thereby improving the measurement accuracy.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
