Description

Technical Field

[0001] This utility model relates to the technical field of bridge pier verticality detection tools, and in particular to a device for detecting the verticality of ultra-high bridge piers. Background Technology

[0002] When using steel formwork 1 for cast-in-place construction of bridge piers, it is necessary to check the verticality of the piers before pouring. This requires using the outer wall of steel formwork 1 for this check. However, when installing steel formwork 1 upwards, a working platform 2 needs to be installed on its outer side to provide space for workers. After installing the working platform 2, looking upwards from below, the extended platform 2 obstructs the view of steel formwork 1, making it inconvenient to use instruments for measurement when the surrounding space is limited. To solve this problem, we propose a verticality detection device for ultra-high bridge piers.

[0003] In the prior art, Chinese patent document CN210141865U, published on March 13, 2020, discloses a verticality detection device for bridge pier column templates. The template verticality detection device includes a pole, a laser generator, and a first screw and a second screw vertically arranged at both ends of the pole. The laser generator is arranged on the first screw and can move horizontally along the first screw. The second screw is provided with a scale. When the pole is vertically stationary, the rays emitted by the laser generator are directly facing the scale. Its advantages are: simple to manufacture and easy to operate. Only the first and second screws at both ends of the upright need to be tightly attached to the template. The verticality of the template can be read on the scale of the second screw on the lower side. Moving the detection device left and right allows for convenient and quick completion of multiple measurements of the template, avoiding the use of A-frame ladders or climbing up and down for measurement, ensuring the safety and speed of measuring and verifying the verticality of the template during operation. Its disadvantages are: firstly, because the working platform 2 is installed on the outside of the steel template 1, the upright cannot be close to the steel template 1; secondly, the laser generator is suspended on the first screw. If the first and second screws are not aligned, the upright needs to be swung to adjust it. At this time, the laser generator will swing violently, making it impossible to quickly observe whether the laser generator is aligned with the scale on the second screw.

[0004] Additionally, Chinese patent document CN215491574U, published on January 11, 2022, discloses a device for controlling the verticality of pier reinforcement cage hoisting. The device includes a mutually compatible transmitting end and receiving end. A laser emitter is installed inside the transmitting end, and a scale is fixedly connected inside the receiving end. The laser emitter is positioned facing the scale. Its advantages are: by placing the laser emitter on the scale to calibrate the verticality of the reinforcement cage, it can effectively improve the hoisting speed of the pier reinforcement cage and accelerate the construction progress. Its disadvantages are: firstly, the device is not convenient to install on the outer wall of the steel formwork 1; secondly, the laser emitter cannot be easily aligned with the scale.

Detailed Implementation

[0032] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0033] Example 1:

[0034] See Figure 1-7A verticality detection device for ultra-high bridge piers includes a first support 100 and a second support 200. The first support 100 includes a first horizontal bar 110 and a first diagonal bar 150. One end of the first horizontal bar 110 is connected to a first magnetic base 120 via a ball joint 111, and the other end is equipped with a detection component. The first diagonal bar 150 is located below the first horizontal bar 110. The upper end of the first diagonal bar 150 is hinged to the first horizontal bar 110 for vertical swinging, and the lower end is hinged to a horizontal swinging device 160 for vertical swinging. The horizontal swinging device 160 is mounted on a second magnetic base 170. The second support 200 includes a second horizontal bar 210. One end of the second horizontal bar 210 is equipped with a third magnetic base 220, and the upper surface of the other end is provided with a scale 231. The first diagonal bar 150 adopts a telescopic adjustment structure. The first bracket 100 and the second bracket 200 can extend to the outside of the working platform 2. The device can be easily installed on the outer wall of the steel template through the magnetic base, and the position of the detection component can be adjusted through the flat device 160 to make it easy for the detection component to be aligned with the scale 231 on the second bracket 200.

[0035] The first magnetic base 120 is used to connect the first horizontal bar 110 to the steel template 1, and the second magnetic base 170 is used to connect the first diagonal bar 150 to the steel template 1. The first magnetic base 120 and the second magnetic base 170 are existing technologies. The first magnetic base 120 and the second magnetic base 170 are respectively provided with knobs. By rotating the knobs, the magnetic force of the magnetic base can be turned on and off.

[0036] The pendulum device 160 is used to adjust the position of the first diagonal bar 150. By swinging the first diagonal bar 150, the front-to-back position and angle of the first horizontal bar 110 can be adjusted.

[0037] Specifically, see Figure 2 When the lower end of the first diagonal bar 150 is swung inward or outward, since the first diagonal bar 150 can only swing up and down relative to the first horizontal bar 110, the first horizontal bar 110 will move back and forth with the first diagonal bar 150, that is, towards the direction inside or outside the drawing. At the same time, since the lower end of the first diagonal bar 150 deviates from the center vertical line of the ball joint 111, the first horizontal bar 110 will also rotate at a certain angle.

[0038] In this embodiment, the detection component uses a plumb line, which includes a thin line and a plumb bob. The upper end of the thin line is tied to a fixed position on the first crossbar 110, and the plumb bob is tied to the lower end of the thin line.

[0039] In one of the solutions, see Figure 4 , 5The pendulum device 160 includes a fixed base 161 and a slider 164. The fixed base 161 has a limiting groove 162, and the slider 164 is slidably connected to the limiting groove 162. The fixed base 161 is mounted on the second magnetic base 170, and the lower end of the first inclined rod 150 is hinged to the slider 164. By pushing the slider 164, the first inclined rod 150 is moved. Since the first horizontal rod 110 is connected to the first magnetic base 120 via a ball joint 111, the first horizontal rod 110 will swing accordingly, thereby adjusting the position of the detection component and facilitating alignment of the detection component with the scale 231 on the second bracket 200.

[0040] Furthermore, the oscillating device 160 also includes an adjusting screw 165. The fixed base 161 has baffles 163 installed on both sides of the limiting slide groove 162. The adjusting screw 165 passes through the limiting slide groove 162 and is rotatably connected to the baffles 163 on both sides. The adjusting screw 165 is threadedly connected to the slider 164. At least one end of the adjusting screw 165 is equipped with a handle 166. By rotating the handle 166 to rotate the adjusting screw 165, the slider 164 can be driven, resulting in higher adjustment precision and better stability.

[0041] In this embodiment, see Figure 2 The upper end of the first inclined rod 150 is hinged to the first horizontal rod 110 through the first hinge seat 151, and the lower end is hinged to the slider 164 through the second hinge seat 152.

[0042] In this embodiment, see Figure 2 The first inclined rod 150 includes a first sleeve rod 153, a second sleeve rod 154, and a first threaded rod 155. The two ends of the first threaded rod 155 are threadedly connected to the first sleeve rod 153 and the second sleeve rod 154, respectively. By rotating the first threaded rod 155, the first sleeve rod 153 and the second sleeve rod 154 move towards or away from each other, thereby adjusting the length of the first inclined rod 150.

[0043] When using, please refer to Figure 1 , 2 First, install the first support 100 on the upper side of the steel formwork 1 of the pier. Then, connect the first horizontal bar 110 to the outer wall of the steel formwork 1 via the first magnetic base 120. With the magnetic force of the second magnetic base 170 deactivated, place the second magnetic base 170 against the outer wall of the steel formwork 1. Place a spirit level on the first horizontal bar 110. After roughly leveling the first horizontal bar 110 by moving the second magnetic base 170, activate the magnetic force of the second magnetic base 170 and install the first support 100 on the steel formwork 1. Finally, by rotating and adjusting the first positive and negative thread screw 155, fine-tune the up-and-down swing of the first horizontal bar 110 to a horizontal state.

[0044] In this embodiment, a plumb line is used. When installing the second bracket 200, the second bracket 200 is located below the plumb line. After leveling the second bracket 200, the verticality can be detected by indicating the scale 231 at the lower tip of the plumb line.

[0045] In this embodiment, the ball joint 111 is a purchased finished product. One end of the ball joint 111 is connected and fixed to the threaded hole on the first magnetic seat 120 by a screw, and the other end can be welded and fixed to the first crossbar 110.

[0046] Example 2:

[0047] Because using a plumb line requires winding and unwinding a thin rope, it is inconvenient to use. Furthermore, the plumb bob swings freely, and in windy conditions, this continuous swinging affects the efficiency and accuracy of the detection. Therefore, the difference between this embodiment and Embodiment 1 is that the detection component in this embodiment uses a laser emitter 130, which is more convenient to use.

[0048] Specifically, a longitudinal through hole 112 is provided at the end of the first crossbar 110 away from the first magnetic base 120. A limiting screw 113 is screwed onto the first crossbar 110 on one side of the through hole 112. The laser emitter 130 is inserted into the through hole 112 and fixed by the limiting screw 113.

[0049] When using, please refer to Figure 1 , 2 First, install the first support 100 on the upper side of the steel formwork 1 of the pier. Then, connect the first horizontal bar 110 to the outer wall of the steel formwork 1 via the first magnetic base 120. With the magnetic force of the second magnetic base 170 deactivated, place the second magnetic base 170 against the outer wall of the steel formwork 1. Place a spirit level on the first horizontal bar 110. After roughly leveling the first horizontal bar 110 by moving the second magnetic base 170, activate the magnetic force of the second magnetic base 170 and install the first support 100 on the steel formwork 1. Finally, by rotating and adjusting the first positive and negative thread screw 155, fine-tune the up-and-down swing of the first horizontal bar 110 to a horizontal state.

[0050] Then install the second bracket 200, which is located below the plumb bob. After leveling the second bracket 200, the verticality is detected by using the light spot indicator of the laser beam 131 to check the scale 231.

[0051] During this process, there may be instances where the spot of the laser beam 131 fails to fall on the scale 231. In this case, it is necessary to rotate the handle 166, and by moving the slider 164 left and right, rotate the first horizontal bar 110 to adjust the laser beam 131 so that the spot of the laser beam 131 points on the scale 231. After rotating the handle 166, the level of the first horizontal bar 110 will change. Then, rotate the first positive and negative thread screw 155 to level it. After leveling, the verticality can be detected by the position of the spot offset.

[0052] Example 3:

[0053] Based on Embodiment 1 or Embodiment 2, a first level 140 is installed on the upper side of the first horizontal bar 110, so that a spirit level is not needed when leveling the first horizontal bar 110.

[0054] Preferably, the first level 140 is a circular universal bubble level.

[0055] Example 4:

[0056] Based on Example 1, Example 2, or Example 3, see [link to example]. Figure 6 The second support 200 also includes a second inclined rod 250. One end of the second horizontal rod 210 is hinged to the third magnetic base 220 for vertical swinging. The second inclined rod 250 is located on the lower side of the second support 200. The upper end of the second inclined rod 250 is hinged to the second horizontal rod 210 for vertical swinging, and the lower end is hinged to the fourth magnetic base 260 for vertical swinging. The second inclined rod 250 includes a third sleeve rod 253, a fourth sleeve rod 254, and a second threaded screw 255. The two ends of the second threaded screw 255 are threadedly engaged with the third sleeve rod 253 and the fourth sleeve rod 254, respectively. With the above structure, the second horizontal rod 210 can be easily leveled when the second threaded screw 255 is rotated.

[0057] By rotating the second forward and reverse threaded screw 255, the third sleeve 253 and the fourth sleeve 254 move towards or away from each other, thereby adjusting the length of the second inclined rod 250.

[0058] Further, see Figure 7 An observation plate 230 is installed on the upper side of the second crossbar 210 at the end away from the third magnetic base 220, and a scale 231 is set on the observation plate 230. The observation plate 230 is set to increase the observation area and facilitate calibration and observation when using a laser emitter.

[0059] Furthermore, a second level 240 is mounted on the upper side of the second crossbar 210. Similarly, the second level 240 is also a circular universal bubble level.

[0060] The method of use or principle of this utility model:

[0061] See Figure 1 When in use, first install the first bracket 100 on the upper side of the steel formwork 1 of the pier column.

[0062] Specifically, the first horizontal bar 110 is first connected to the outer wall of the steel template 1 via the first magnetic base 120. With the magnetic force of the second magnetic base 170 turned off, the second magnetic base 170 is placed against the outer wall of the steel template 1. By moving the second magnetic base 170 and observing the first level 140, after roughly leveling the first horizontal bar 110, the magnetic force of the second magnetic base 170 is turned on, and the first bracket 100 is installed on the steel template 1. Then, by rotating and adjusting the first positive and negative thread screw 155, the first horizontal bar 110 is adjusted to a horizontal state by fine-tuning its up-and-down swing.

[0063] The second support 200 is installed on the lower side of the steel formwork 1 of the pier column, and the second support 200 is located directly below the first support 100.

[0064] Specifically, the second crossbar 210 is first connected to the outer wall of the steel template 1 via the third magnetic chuck 220. With the magnetic force of the fourth magnetic chuck 260 turned off, the fourth magnetic chuck 260 is placed against the outer wall of the steel template 1. By moving the fourth magnetic chuck 260, the second level 240 is observed. After roughly leveling the second crossbar 210, the magnetic force of the fourth magnetic chuck 260 is turned on, and the second bracket 200 is installed on the steel template 1.

[0065] If the spot of laser beam 131 does not fall on the observation plate 230, turn handle 166 and rotate the first horizontal bar 110 by moving slider 164 left and right, thereby adjusting laser beam 131 so that the spot of laser beam 131 is on the observation plate 230. After turning handle 166, the level of the first horizontal bar 110 will change. Then turn the first positive and negative thread screw 155 to level it. After leveling, the verticality can be detected by the position of the spot offset.

[0066] See Figure 7 When the light spot is located on the zero mark in the middle of the observation plate 230, it indicates that the steel template 1 is in a vertical state. The distance of the light spot from the zero mark in the middle of the observation plate 230 is used to determine whether the verticality of the steel template 1 meets the requirements.

[0067] During inspection, this inspection device can be installed on both sides of the steel formwork 1 to inspect the verticality of the steel formwork 1 in different directions.
