Technical Field

The utility model relates to a pier stud detection area, concretely relates to vertical degree measuring device of pier stud.

Background

The vertical degree of a pier column is an important index for pier column construction, and the conventional method for measuring the vertical degree of the pier column comprises the following three steps: the method comprises the following steps that firstly, a plumb line method is used for testing under a windless condition, a plumb line hammer is hung along a pier column testing part, after the plumb line hammer is stable, the horizontal distance from the upper part of the pier column to a plumb line and the horizontal distance from the lower part of the pier column to the plumb line within a testing range are measured by using a measuring ruler, and meanwhile, the height of the pier column within the testing range is measured; the theodolite plumb method comprises the steps that a plumb line provided by a theodolite is utilized, the horizontal distance from the upper part of a pier column to the plumb line and the horizontal distance from the lower part of the pier column to the plumb line in a test range are measured by a straight steel ruler, two distance values are read through the intersection point of the plumb line in an instrument telescope and the straight steel ruler, and the height of the pier column in the test range is measured at the same time; and thirdly, erecting the total station on the front side of the pier stud test by using a parallel distance method of the total station, measuring the horizontal distance from the upper part to the instrument and the horizontal distance from the lower part to the instrument in the test range of the structure by using the prism-free distance measurement function of the total station, and measuring the height of the pier stud in the test range by using the total station.

However, in the three methods, the plumb method is susceptible to windy weather and the plumb line is stationary and consumes a long time, and the theodolite plumb method and the total station parallel distance method require the use of theodolite or total station equipment, and the test process is complicated.

Therefore, it is necessary to develop a device for measuring the vertical degree of a pier in order to solve the above problems.

Disclosure of Invention

The utility model aims at providing a pier stud verticality measuring device to solve the problem that exists among the prior art.

In order to realize the utility model discloses the technical scheme that the purpose and adoption are such, a pier stud straightness measuring device, including triangle base, laser instrument and scale.

The triangle base is arranged in one side of pier stud and has the clearance with the pier stud, and the upper surface of triangle base is the horizontality, and the laser instrument is installed at triangle base upper surface.

The graduated scale level sets up and is close to the bottom of pier stud, and the one end of graduated scale supports tightly and its length direction is unanimous with the radial of pier stud with the lateral wall of pier stud.

When the pier stud is in a measuring state, a vertical laser line emitted by the laser instrument is tangent to the side wall of the pier stud close to the top of the pier stud, a gap exists between the vertical laser line and the side wall of the pier stud close to the bottom of the pier stud, and the vertical laser line is marked on the graduated scale.

Further, the triangular base is provided with a leveling device.

Further, the vertical laser line emitted by the laser instrument is LD green light.

The technical effect of the utility model is undoubted, the vertical laser line that the device adopted the laser instrument to send is measured, has solved the plumb line method and has easily received the long problem of duration of windstorm weather influence and plumb line pendulum static, and laser instrument easy operation, and the test procedure is more convenient, high-efficient in theodolite plumb method and total powerstation square method relatively.

Fig. 1 is a schematic view of the device of the present invention.

In the figure: triangle base 1, laser instrument 2, scale 3, pier stud 4 and vertical laser line 5.

Detailed Description

The present invention will be further described with reference to the following examples, but it should not be construed that the scope of the present invention is limited to the following examples. Various substitutions and modifications can be made without departing from the technical spirit of the invention and according to the common technical knowledge and conventional means in the field, and all shall be included in the scope of the invention.

The embodiment discloses a pier stud verticality measuring device, which comprises a triangular base 1, a laser instrument 2 and a graduated scale 3.

Referring to fig. 1, the triangular base 1 is arranged on one side of the pier stud 4 and has a gap with the pier stud 4, the upper surface of the triangular base 1 is horizontal, and the laser instrument 2 is arranged on the upper surface of the triangular base 1. In this embodiment, the laser 2 is an automatic laser bonding level.

The triangular base 1 is provided with a leveling device, and in the embodiment, the leveling device selects a leveling nut.

The horizontal setting of scale 3 just is close to the bottom of pier stud 4, and the one end of scale 3 supports tightly and its length direction is unanimous with pier stud 4's radial with the lateral wall of pier stud 4, and scale 3 has certain rigidity.

Have inclination pier stud 4 when measuring state, the vertical laser line 5 that laser instrument 2 sent is tangent with the lateral wall that pier stud 4 is close to its top, and this one side and the horizontal plane of pier stud 4 form the acute angle, and there is the clearance vertical laser line 5 and pier stud 4 are close to the lateral wall of its bottom, and vertical laser line 5 is beaten on scale 3.
