Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to a building engineering verticality detection mechanism. Background Technology

[0002] In building construction, to improve the quality of building walls, especially in large-span, high-rise buildings such as large basement buildings or the flatness and verticality of shear walls in high-rise and super high-rise buildings, the verticality of the shear walls can directly cause changes in the overall displacement and tilt of the walls during construction along the high-rise buildings. This leads to changes in the direction of external force release during the load-bearing process of the shear walls, affecting the stability and shear failure resistance of the building. Therefore, to ensure that the quality of the completed building meets the requirements and construction specifications, it is necessary to manually test the verticality of the shear walls before and after construction to check whether the overall angle between the wall and the horizontal plane after completion meets the requirements.

[0003] Chinese patent document CN218120870U discloses a verticality testing mechanism for building engineering quality inspection, including a connecting plate with a groove. A pin is rotatably connected to the groove via a bearing. A hinge plate is fixedly connected to the pin, and a hinge rod is hinged to the hinge plate. A slider is hinged to the hinge rod and slidably disposed within the groove. A positioning mechanism is provided on the slider. This invention fixes the angle between the connecting plate and the hinge plate, allowing the device to be placed in a well-lit area for angle observation, preventing angle changes and ensuring accuracy during testing. The existing technology has the following problems:

[0004] The verticality testing mechanism described in the aforementioned literature requires placing the connecting plate on the building's interior floor and ensuring the hinge plate is tightly against the wall to perform verticality testing. This means that if the building's floor is uneven or even tilted, the verticality test results will be affected, leading to inaccurate measurements. Additionally, the distance between the dial and the hinge plate in the literature requires the testing personnel to align the dial's scale with the hinge plate's angle after each measurement to determine the offset angle. This process is inefficient and may introduce errors. Utility Model Content

[0005] This utility model provides a verticality testing mechanism for building engineering to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A verticality testing mechanism for building construction includes a horizontal frame. A testing mechanism is located on the front bottom side of the horizontal frame, and a wall-mounting mechanism is located on the rear side of the horizontal frame. The testing mechanism includes two hanging plates, both of which are fixedly installed on the front bottom side of the horizontal frame. A connecting rod is fixedly installed between the opposite faces of the two hanging plates. A transparent semi-circular scale is fixedly installed on the right side of the right hanging plate. A bearing collar is sleeved on the outer wall of the connecting rod. A first suspension plate is fixedly installed at the bottom of the bearing collar. An installation cylinder is fixedly installed at the bottom of the first suspension plate. A laser emitter is engaged in the inner cavity of the installation cylinder. The laser emitting end of the laser emitter is located behind the scale line of the transparent semi-circular scale. A second suspension plate is fixedly installed at the bottom of the installation cylinder, and a metal counterweight is fixedly installed at the bottom of the second suspension plate.

[0008] A further improvement of this utility model is that: a threaded hole penetrating its inner cavity is provided on the front side of the mounting cylinder, a threaded rod is threaded on the inner ring of the threaded hole, the rear end of the threaded rod penetrates into the inner cavity of the mounting cylinder and is fixedly bonded with a silicone sheet, the rear side of the silicone sheet is attached to the front side of the laser emitter, and a knob is fixedly installed on the front end of the threaded rod.

[0009] A further improvement of this utility model is that: a movable ring is movably installed on the outer wall of the knob, and an anti-loss rope is fixedly installed on the outer wall of the movable ring; the other end of the anti-loss rope is fixedly connected to the left front end of the mounting cylinder.

[0010] A further improvement of this utility model is that a magnetic positioning plate is fixedly installed at the bottom of the horizontal frame, and the bottom of the magnetic positioning plate is attracted to the rear side of the horizontal metal counterweight.

[0011] A further improvement of this utility model is that a hand handle is fixedly installed on the bottom rear side of the horizontal frame, and the outer wall of the hand handle is covered with an anti-slip rubber sleeve.

[0012] A further improvement of the present invention is that the wall-mounting mechanism includes a vertical plate, which is fixedly installed on the rear side of the horizontal frame. A rubber pad is fixedly bonded to the rear side of the vertical plate, and a plurality of rubber protrusions are provided on the rear side of the rubber pad.

[0013] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0014] 1. This utility model provides a building engineering verticality testing mechanism.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figure 1 , Figure 2As shown, this utility model provides a verticality testing mechanism for building engineering, including a horizontal frame 1. A testing mechanism 2 is provided on the bottom front side of the horizontal frame 1, and a wall-mounting mechanism 3 is provided on the rear side of the horizontal frame 1. The testing mechanism 2 includes two hanging plates 21, both of which are fixedly installed on the bottom front side of the horizontal frame 1. A connecting rod 22 is fixedly installed between the opposite surfaces of the two hanging plates 21. A transparent semi-circular scale 23 is fixedly installed on the right side of the right hanging plate 21. A bearing collar 24 is sleeved on the outer wall of the connecting rod 22. A first suspension plate 25 is fixedly installed at the bottom of the bearing collar 24. An installation cylinder 26 is fixedly installed at the bottom of the first suspension plate 25. A laser emitter 27 is snapped into the inner cavity of the installation cylinder 26. The laser emitting end of the laser emitter 27 is located behind the scale line of the transparent semi-circular scale 23. A second suspension plate 28 is fixedly installed at the bottom of the installation cylinder 26. A metal counterweight 29 is fixedly installed at the bottom of the second suspension plate 28.

[0024] In use, by pressing the wall-mounted mechanism 3 against the surface of the shear wall whose verticality needs to be tested, the horizontal frame 1 is perpendicular to the wall surface at a 90-degree angle. When the shear wall tilts, the suspended metal counterweight 29 can cause the bearing collar 24 to rotate on the outer wall of the connecting rod 22 between the two hanging plates 21. This causes the laser emitted from the front end of the laser emitter 27 inside the mounting cylinder 26 between the first hanging plate 25 and the second hanging plate 28 to pass through the transparent semi-circular scale 23. Since the transparent semi-circular scale 23 is fixedly installed on the right side of the right hanging plate 21, the position of the transparent semi-circular scale 23 will not change. At this time, the inspector only needs to observe the angle at which the laser passes through the transparent semi-circular scale 23 to determine the tilt angle of the wall, without having to lean against the ground to test the verticality of the wall.

[0025] like Figure 3 As shown, the front side of the mounting cylinder 26 has a threaded hole 261 that passes through its inner cavity. The inner ring of the threaded hole 261 is threaded with a threaded rod 265. The rear end of the threaded rod 265 passes through the inner cavity of the mounting cylinder 26 and is fixedly bonded with a silicone sheet. The rear side of the silicone sheet is attached to the front side of the laser emitter 27. The front end of the threaded rod 265 is fixedly mounted with a knob 264. The outer wall of the knob 264 is movably mounted with a movable ring 263. The outer wall of the movable ring 263 is fixedly mounted with an anti-loss rope 262. The other end of the anti-loss rope 262 is fixedly connected to the left side of the front end of the mounting cylinder 26.

[0026] The laser emitter 27 is powered by a button battery. During installation, simply insert it into the mounting cylinder 26, align the threaded rod 265 with the threaded hole 261, and rotate the knob 264. The threaded connection between the threaded rod 265 and the threaded hole 261, along with the silicone pad at its front end, secures the laser emitter 27 to the outer wall, ensuring its stability during use. When it is necessary to disassemble the laser emitter 27 to replace the battery, simply reverse the knob 264 to disengage the threaded rod 265 from the threaded hole 261, allowing the laser emitter 27 to be pulled out of the mounting cylinder 26. The knob 264, once rotated, can be prevented from being lost by using the anti-loss rope 262 on the outer wall of the rotating ring 263 to connect with the mounting cylinder 26, facilitating future use.

[0027] like Figure 4 , Figure 5 As shown, a magnetic positioning plate 11 is fixedly installed at the bottom of the horizontal frame 1. The bottom of the magnetic positioning plate 11 is attracted to the rear side of the horizontal metal counterweight 29. A hand handle 12 is fixedly installed at the bottom rear side of the horizontal frame 1. The outer wall of the hand handle 12 is covered with an anti-slip rubber sleeve. The wall-mounting mechanism 3 includes a vertical plate 31. The vertical plate 31 is fixedly installed at the rear side of the horizontal frame 1. A rubber pad 32 is fixedly bonded to the rear side of the vertical plate 31. Several rubber protrusions 33 are provided on the rear side of the rubber pad 32. The several rubber protrusions 33 are all in contact with the detection wall.

[0028] During testing, the entire horizontal frame 1 can be picked up by holding the handle 12. When testing is not required, the metal counterweight 29 can be rotated clockwise and then attracted and fixed to the magnetic positioning plate 11 at the bottom of the horizontal frame 1 to avoid being shaken during handling. When the wall-mounted mechanism 3 is used to press against the wall, the frictional resistance between the vertical plate 31 and the wall can be increased by the rubber pad 32 on the back of the vertical plate 31 and several rubber protrusions 33 on the back of the rubber pad 32, thereby improving the stability during the verticality testing process.

[0029] The working principle of this building verticality testing agency will be explained in detail below.

[0030] like Figure 1-5As shown, during use, by pressing the wall-mounting mechanism 3 against the surface of the shear wall whose verticality needs to be tested, the horizontal frame 1 is perpendicular to the wall surface at a 90-degree angle. When the shear wall tilts, the suspended metal counterweight 29 causes the bearing collar 24 to rotate on the outer wall of the connecting rod 22 between the two hanging plates 21. This causes the laser emitted from the front end of the laser emitter 27 inside the mounting cylinder 26 between the first hanging plate 25 and the second hanging plate 28 to pass through the transparent semi-circular scale 23. Since the transparent semi-circular scale 23 is fixedly installed on the right side of the right hanging plate 21, its position will not change. At this time, the inspector only needs to observe the angle at which the laser passes through the transparent semi-circular scale 23 to determine the tilt angle of the wall. The laser emitter 27 is powered by a button battery. During installation, simply insert it into the mounting cylinder 26, then align the threaded rod 265 with the threaded hole 261 and rotate the knob 264. The laser emitter 27 can be used to determine the tilt angle of the wall by observing the angle at which the laser passes through the threaded hole 261. The connection utilizes the silicone sheet at its front end to hold the laser emitter 27 against the outer wall, thus securing the laser emitter 27 and ensuring its stability during use. When the laser emitter 27 needs to be disassembled to replace the battery, simply reverse the knob 264 to disengage the threaded rod 265 from the threaded hole 261, allowing the laser emitter 27 to be pulled out of the mounting cylinder 26. The knob 264, which has been rotated off, can be prevented from being lost by using the anti-loss rope 262 on the outer wall of the rotating ring 263 to connect with the mounting cylinder 26, facilitating future use. During testing, the entire horizontal frame 1 can be lifted by holding the handle 12. When testing is not required, the metal counterweight 29 can be rotated clockwise and then attracted and fixed to the magnetic positioning plate 11 at the bottom of the horizontal frame 1, preventing it from being flung around during handling. When the wall-mounted mechanism 3 is used to press against the wall, the rubber pad 32 on the back of the vertical plate 31 and several rubber protrusions 33 on the back of the rubber pad 32 can be used to increase the frictional resistance between the vertical plate 31 and the wall, improving the stability during the verticality testing process.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
