Building verticality measuring device
Technical Field
The invention relates to a measuring device, in particular to a building verticality measuring device.
Background
The engineering monitoring means that in the construction process of a building structure, a monitoring instrument is adopted to monitor each control index of a key part, and an alarm is given when a monitoring value is close to a control value, so that the safety of construction is ensured, and the engineering monitoring method can also be used for checking whether the construction process is reasonable.
Perpendicularity measurement is a condition that a measured element on a part maintains a correct 90-degree included angle relative to a reference element. I.e. the degree to which orthogonality between the two elements is maintained.
There are many methods for measuring perpendicularity. There are also special verticality measuring instruments on the market for measuring verticality. However, if the tolerance range is small, a general measuring instrument may not measure the tolerance range. It is recommended that the perpendicularity tolerance be within 0.05mm, or that the measurement be made with a three-coordinate measuring machine. This paper mainly introduces the use of a three-coordinate measuring machine to measure perpendicularity.
At present along with the rapid development of real estate, the security of building construction also receives more and more attention, wherein the straightness that hangs down is the important index of measuring building safety, but present a lot of straightness measurement all be that construction worker climbs to the wall body then down with the plummet, then let another workman observe the distance of deviation in the below, do so not only make the workman on the wall body dangerous, still extravagant manpower goes to observe the reading, waste time again, and the accuracy of measurement still can the deviation moreover, consequently need a high-precision building straightness measuring device that hangs down urgently.

Because still including fixed block 6, first flat board 61, second flat board 63, ruler 64, protractor 65 and spring 66, the left wall fixedly connected with fixed block 6 of the front side of mounting panel 5, the outside sliding connection of fixed block 6 has first flat board 61, first flat board 61 is last to open has a word hole 62, fixed block 6 sliding connection is in first flat board 61 last word hole 62, the top fixedly connected with second flat board 63 of first flat board 61, the front side of second flat board 63 is provided with ruler 64, the right-hand member rotary type of second flat board 63 is connected with protractor 65, the one end of spring 66 is connected with first flat board 61, the other end of spring 66 is connected with the top of sweep 1. Therefore, when the lead weight 510 is stable, a worker can pull the angle square 65 to move rightwards, the angle square 65 drives the second flat plate 63 to move rightwards, the second flat plate 63 drives the first flat plate 61 to move rightwards, meanwhile, the spring 66 is stretched, then the worker can rapidly measure the offset angle and the offset distance by using the angle square 65 and the ruler 64, after reading is completed, the spring 66 drives the first flat plate 61 to reset, the first flat plate 61 drives the second flat plate 63 to move leftwards, and therefore the function of rapid measurement is achieved.
Because the automobile turning plate further comprises a second fixing plate 7, a guide rod 72, a screw 74, a second support plate 75 and a first magnet 76, the second fixing plate 7 is fixedly connected to the right side of the upper portion of the turning plate 1, a guide hole 71 is horizontally formed in the bottom of the second fixing plate 7, the guide rod 72 is connected in the guide hole 71 in a sliding mode, a screw hole 73 is vertically formed in the upper portion of the second fixing plate 7, the screw 74 is matched in the screw hole 73, the screw 74 is in contact with the guide rod 72, the second support plate 75 is fixedly connected to the right side of the upper portion of the guide rod 72, and the first magnet 76 is arranged at the. Therefore, if a large amount of wind blows the lead weight 510 during measurement, a worker can unscrew the screw 74, pull the second support plate 75 to move rightward, and then the guide rod 72 plays a role in guiding, so that the second support plate 75 cannot swing to two sides, the second support plate 75 drives the first magnet 76 to move to the bottom of the lead weight 510, and therefore the lead weight 510 is quickly stabilized, and after the lead weight 510 is stabilized, the first magnet 76 is moved away, and then the screw 74 is screwed, so that the function of quickly stabilizing the lead weight 510 is achieved.
Because still including protective sheath 8 and second magnet 10, the top fixedly connected with protective sheath 8 of swinging arms 55, protective sheath 8 is inside to be opened has cavity 9, and first pulley 59 is located cavity 9, and the bottom right side of protective sheath 8 is provided with second magnet 10. Therefore, the first pull rope 47 is not easy to slide to both sides after the protective sleeve 8 is added, and the lead weight 510 is attracted by the second magnet 10 after the swinging rod 55 is retracted, so that the lead weight 510 is prevented from falling, and the function of protecting workers is realized.
Because still including infrared emitter 12 and transparent baffle 13, vertically open in the plummet 510 has second through-hole 11, is provided with infrared emitter 12 in the second through-hole 11, and infrared emitter 12 shines perpendicularly downwards, is connected with transparent baffle 13 on the drill way of the second through-hole 11 on the plummet 510. The infrared ray emitter 12 emits light to irradiate the ruler 64, thereby realizing a function of improving the accuracy of measurement.
The above examples are merely representative of preferred embodiments of the present invention, and the description thereof is more specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, various changes, modifications and substitutions can be made without departing from the spirit of the present invention, and these are all within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
