Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to a verticality positioning device for a steel casing. Background Art
[0002] In pile foundation engineering, it is necessary to bury a steel casing before opening a pile hole to prevent surface water and sundries from flowing into the drill hole. In addition, the steel casing also plays a role in positioning and guiding the center of the drill hole.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the following will clearly and completely describe the technical solutions of the embodiments of the present disclosure with reference to the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts fall within the scope of protection of the present disclosure.
[0023] Please refer to Figures 1-3 , a verticality positioning device for a steel casing 4, including two fixing parts 1 for connecting with the soil, and a transmitting part 2 and a receiving part 3 are respectively arranged on the two fixing parts 1; the transmitting part 2 includes a first vertical rod 21 arranged on the fixing part 1, and two laser transmitters 22 are arranged on the first vertical rod 21; the receiving part 3 includes a second vertical rod 31 fixedly arranged on the fixing part 1, two laser receivers 32 are arranged on the second vertical rod 31, and a warning lamp 33 is also arranged on the second vertical rod 31.
[0024] Through the arranged transmitting part 2 and receiving part 3, first insert the fixing part 1 equipped with the receiving part into the soil, and then insert the fixing part 1 equipped with the transmitting part 2 into the opposite side of the steel casing 4, so that the laser emitted by the laser transmitter 22 can be tangent to the outer surface of the steel casing 4. If the steel casing 4 is in an inclined state and the laser is blocked by the steel casing 4, one of the laser transmitters 22 cannot receive the laser, and the warning lamp 33 is in an extinguished state; when both laser transmitters 22 can receive the laser, it indicates that the steel casing 4 is in a vertical state at this time, and the warning lamp 33 is in a lit state.
[0025] Further, the fixing part 1 includes a fixing plate 11, and a plurality of fixing rods 12 are arranged at the bottom of the fixing plate 11. Each fixing rod 12 is inserted into the soil to fix the fixing plate 11. The end of each fixing rod 12 is provided with a pointed shape. The fixing plate 11 should be kept in a horizontal state, and the levelness of the fixing plate 11 can be measured by using a spirit level, or the spirit level can be directly installed on the fixing plate 11.
[0026] Further, the first vertical rod 21 is slidably arranged on the fixing plate 11. Thereby, the position of the laser transmitter 22 can be adjusted to facilitate precise adjustment so that the laser is tangent to the outer wall of the steel casing 4.
[0027] Furthermore, the laser emitter 22 is slidably disposed in a chute 24 on the first vertical rod 21, and a locking device is provided on each of the first vertical rods 21. Due to the complex construction site conditions, the light emitted by the laser emitter 22 may be blocked by objects at the site. At this time, the laser emitter 22 can be slid to adjust its position, which is more convenient for operation and practical use. Correspondingly, the laser receiver 32 should cover the range where the laser emitter 22 moves, that is, after the laser emitter 22 adjusts its position, the laser receiver 32 can still receive the laser.
[0028] Furthermore, the locking device includes a bolt 23 threadedly connected to the laser emitter 22, and the end of the bolt 23 passes through a slot 25 on the first vertical rod 21. Loosen the bolt 23 so that the head of the bolt 23 is separated from the first vertical rod 21, and the laser emitter 22 can slide in the chute 24. When adjusted to a suitable position, tighten the bolt 23, and fasten the laser emitter 22 through the frictional force between the head of the bolt 23 and the first vertical rod 21.
[0029] Working principle: First, insert the fixing part 1 equipped with the receiving part into the soil, then insert the fixing part 1 equipped with the emitting part 2 into the opposite side of the steel casing 4. Move the first vertical rod 21 and adjust the laser emitter 22 to a suitable position so that the laser emitted by the laser emitter 22 can be tangent to the outer surface of the steel casing 4. If the steel casing 4 is in an inclined state and the laser is blocked by the steel casing 4, then one of the laser emitters 22 cannot receive the laser, and the indicator light 33 is in an extinguished state; when both laser emitters 22 can receive the laser, it indicates that the steel casing 4 is in a vertical state at this time, and the indicator light 33 is in a lit state. The structure of the present utility model is simple and easy to operate, and can quickly determine whether the verticality of the steel casing 4 is qualified, improving the construction efficiency and the quality of the pile foundation.
[0030] Only some exemplary embodiments of the present utility model have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present utility model, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present utility model.
