Abstract
Description
Technical Field
[0001] This utility model belongs to the field of building construction technology, specifically relating to a rapid detection device for the verticality of steel column installation. Background Technology
[0002] Steel structures are widely used in large factories, stadiums, and high-rise buildings due to their significant advantages such as light weight, simple construction, high construction efficiency, and short construction period. Steel structures are mainly composed of steel beams, steel columns, steel trusses, and other components made of shaped steel and steel plates. Among these, the installation of steel columns is of paramount importance, and ensuring the verticality of the steel columns meets requirements is a crucial step, requiring precise measurement.
[0003] In existing technologies, the verticality of steel columns requires the use of multiple theodolites. The theodolites are set up against the side of the column, leveled, and aimed at the bottom edge. By swinging the theodolite lens up and down, the telescope is slowly raised to the top, and the column is observed to see if it deviates from the crosshair center line. Measurements are taken at different positions on the column, and the real-time verticality is then calculated. This method has the advantage of high accuracy, approximately ±3mm / m; however, its disadvantages are equally apparent. It requires specialized technicians to continuously operate the theodolites, resulting in numerous operations and low efficiency, which hinders the improvement of work efficiency. Utility Model Content
[0004] The purpose of this invention is to provide a rapid detection device for the verticality of steel columns. By observing the deviation of the laser spot positions on the top and bottom target plates of the steel column, the verticality of the steel column can be determined, thereby improving the detection speed.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A rapid detection device for the verticality of a steel column includes three mounting rings that are respectively clamped at different heights above and below the steel column. A laser plumb bob is installed on the top mounting ring, and a first receiving target and a second receiving target are installed on the mounting rings at the middle and bottom of the steel column. Each mounting ring includes two flexible clamping strips, and a butt joint is provided at both ends of the clamping strips. Each butt joint is provided with a threaded connection hole, and a connection hole is provided on one of the flexible clamping strips. The first receiving target (6) and the second receiving target are fixed to the flexible clamping strips by screws.
[0007] Furthermore, the mounting ring is provided with a detachable mounting base plate, which includes two connecting rods and a mounting groove disposed between the two connecting rods.
[0008] Furthermore, multiple mounting threaded holes are provided on both sides of the mounting groove.
[0009] Furthermore, the mating connector includes a mating concave head and a mating convex head, and the mating concave head and the mating convex head are respectively disposed at one end of the clamping strip.
[0010] Furthermore, the first receiving target includes a transparent mesh plate, and the second receiving target is aligned with the first receiving target.
[0011] Furthermore, the mounting grooves on the mounting rings at the middle and bottom of the steel column are respectively adapted to the size of the first receiving target and the second receiving target.
[0012] Compared with the prior art, the advantages of this utility model are as follows: This utility model uses independent and detachable mounting rings at different height positions of the steel column. The mounting rings are fixed to the steel column, and a laser plumb bob and a target for receiving laser signals are installed on the mounting rings respectively. The verticality of the steel column is determined by the offset of the laser point position of the laser plumb bob on the target. The measurement is fast and easy to read and simple to operate.

[0024] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.
[0025] like Figures 1-2As shown, a rapid verticality detection device for a steel column 1 includes three mounting rings that are respectively clamped at different heights above and below the steel column 1. A laser plumb bob is installed on the top mounting ring, and a first receiving target 6 and a second receiving target are installed on the mounting rings at the middle and bottom of the steel column 1. The mounting ring includes two flexible clamping strips, and a butt joint is provided at both ends of the clamping strips. A threaded connection hole is provided on the butt joint, and a connection hole is provided on one of the flexible clamping strips. The first receiving target (6) and the second receiving target are fixed to the flexible clamping strips by screws.
[0026] Compared to existing technologies, the verticality detection of steel column 1 requires the use of multiple theodolites. The theodolites are mounted on the side of the steel column 1, leveled, and aimed at the bottom edge. The theodolite lens is then slowly raised to the top by swinging it up and down, observing whether the steel column 1 deviates from the crosshair center line. The scale readings at different positions on the steel column 1 are then taken, and the real-time verticality of the steel column 1 is calculated. This method requires highly skilled operators familiar with the equipment, making it difficult to operate and necessitating professional operator training. In this invention, the verticality detection of steel column 1 is simplified. Three different mounting rings are set at different heights on the steel column 1, and clamps are used to quickly fix the mounting rings to the steel column 1, reducing operational difficulty. A laser plumb bob or target is then fixed to each mounting ring. The verticality deviation of the steel column 1 is determined by the laser signal emitted by the laser plumb bob. The overall operation is simple and easy to implement.
[0027] The mounting ring is equipped with a detachable mounting base plate 2, which includes two connecting rods 3 and a mounting groove 4 between the two connecting rods 3. Multiple threaded mounting holes 5 are provided on both sides of the mounting groove 4. The mounting groove 4 is used to fix a laser plumb bob or to mount a target.
[0028] The mating connector includes a mating concave head 9 and a mating convex head 8, and the mating concave head 9 and the mating convex head 8 are respectively disposed at one end of the clamping strip.
[0029] The first receiving target 6 includes a transparent mesh plate, and the second receiving target is aligned with the first receiving target 6. The mounting grooves 4 on the mounting rings at the middle and bottom of the steel column 1 are adapted to the sizes of the first receiving target 6 and the second receiving target, respectively.
[0030] In practical use, a mounting ring is clamped at three different height positions on the steel column 1. A laser plumb bob should be installed on the highest mounting ring. A first receiving target 6 and a second receiving target are then installed on the second and third mounting rings, respectively. The laser plumb bob emits a laser signal, which passes through the first receiving target 6 and illuminates the second receiving target. By observing the deviation between the laser point on the first receiving target 6 and the laser point on the second receiving target, the verticality deviation of the steel column 1 can be calculated.
[0031] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
