Description

Technical Field

[0001] The invention belongs to the field of steel structure installation and construction, and in particular relates to a measuring tool for adjusting the verticality of a steel column. Background Art

[0002] Generally, a magnetic plumb bob is used to measure the verticality of a single-story steel column with a relatively low height. This instrument uses the principle that the plumb bob's deadweight pulls a line to form a vertical line to measure verticality. The magnetic plumb bob is fixed to the highest end of the steel column, the plumb bob is pulled down, and the plumb bob is gently touched by hand to make it still. A steel ruler (or steel tape measure) is used to measure the distance between the magnetic plumb line and the steel column.

[0003] At least measure the distances of the top, middle and bottom points. Take the maximum value as the judgment standard. This method will cause the plumb line to shake due to the large height of the steel column, and outdoor construction is usually accompanied by a breeze, so it is difficult for the plumb line to measure accurately in this environment. Summary of the invention

[0004] The purpose of the present invention is to provide a measuring tool for adjusting the verticality of a steel column in order to overcome the problems of the prior art. The measuring tool ensures the stability of the output laser light, thereby improving the accuracy of the measurement result.

[0006] A measuring tool for adjusting the verticality of a steel column, the measuring tool comprising a shell, a magnet and a laser; the magnet is arranged on the side wall of the shell; the laser is located inside a cavity formed by the shell, and is connected and fixed to the shell via a support rod; a counterweight ball is arranged at the end of the laser, and the light emitting end of the laser emits light through a light emitting hole at the top of the shell; and the support rod is connected to the laser via a ball joint connector.

[0007] According to a preferred embodiment, a groove structure is provided on the side wall of the shell, and the magnet is embedded in the groove structure.

[0014] Beneficial effects of the present invention: The measuring tool of the present invention eliminates the plumb line used in traditional technology and adds a laser line to control verticality.

The housing 201 is used to provide structural support for the magnet 202 and the laser 203.

[0022] Preferably, the magnet 202 is disposed on a side wall of the housing 201 .

[0023] Furthermore, a groove structure is provided on the side wall of the housing 201, and the magnet 202 is embedded in the groove.

[0024] By embedding the magnet 202 on the housing 201 , the measuring tool 200 can be attached to the steel column 100 to be measured by magnetic force.

[0025] Preferably, the laser 203 is located inside the cavity formed by the shell 201 and is connected and fixed to the shell 201 via a support rod 205 .

[0026] A weighted ball 204 is disposed at the end of the laser 203, and the light-emitting end of the laser 203 emits light through a light-emitting hole 206 at the top of the housing 201. For example, the weighted ball 204 may be made of ceramic.

[0027] The support rod 205 is connected to the laser 203 via a ball joint connector.

[0028] Thus, the laser line emitted from the light-emitting end of the laser 203 is always kept in a vertical state by the connection between the weight ball 204 at the end of the laser 203 and the support rod 205, thereby overcoming the problem of inaccurate measurement caused by the shaking of the pendulum in the prior art.

[0029] Preferably, the light exit hole 206 is a trumpet-shaped structure.

Furthermore, three points at different heights above the steel column 100 can be selected to measure the distance between the laser line and the steel column 100 at each point, so as to evaluate whether the steel column 100 is in a vertical state.

[0034] That is, the measuring tool 200 of the present invention eliminates the plumb line of the traditional technology and adds a laser line to control the verticality. The measuring tool 200 mainly consists of three components, namely a magnet 202, a laser 203 and a counterweight ball 204.

Under the action of the deadweight ball 204, the laser 203 is perpendicular to the ground, ensuring that the light source can always be perpendicular to the ground. The measuring tool 200 is placed at the bottom of the column, and the distance between the laser line and the steel column 100 at the upper, middle and lower positions of the steel column 100 can be used to complete the verticality evaluation of the steel column 100.
