Embodiment 1

[0031] A steel structure measuring method, the method uses a steel structure positioning device to position a steel column 15. Such as figure 2 As shown, the positioning device of the steel structure includes a prism 13 , a connecting rod 12 , a connecting frame and a second bolt 8 . The connecting frame includes a connecting plate 1 and a bracket 2, the connecting plate 1 is located at the upper end of the supporting frame 2 and is welded with the supporting frame 2. The lower end of the connecting rod 12 passes through the center of the connecting plate 1 and is welded with the connecting plate 1 . The upper end of the connecting rod 12 is fixedly connected with the prism 13 . The positioning device of the steel structure also includes four positioning rods 3 which are evenly distributed along the circumference of the connecting frame. Specifically, each positioning rod 3 is welded to the end of the bracket 2 respectively. A positioning portion is slidably connected to a...

Embodiment 2

[0044] Such as Figure 6 As shown, the difference between this embodiment and Embodiment 1 is that this embodiment also includes a rotating shaft, a gear 19 , a first rack 17 and a second rack 18 . In this embodiment, there are two positioning rods 3, and the two positioning rods 3 are perpendicular to each other and are not on the same horizontal plane. The central point of each positioning rod 3 coincides with the axis of the connecting rod 12 . The interior of the positioning rod 3 is hollow to form an accommodating chamber 23 , and the upper end surfaces of the left and right sides of the positioning rod 3 are provided with strip-shaped grooves 21 , and the strip-shaped grooves 21 communicate with the accommodating chamber 23 . A gear 19 is rotatably connected to the middle of the accommodation chamber 23 through a rotating shaft, and a spring 20 is arranged in the accommodation chamber 23, and the spring 20 is fixedly connected to the rotating shaft. A first rack 17 is ...

Abstract

The invention belongs to the field of devices for measuring distance, level or azimuth, and specifically discloses a method for measuring a steel structure, comprising the following steps: (1) installing a total station; (2) installing a steel structure on the upper end of the steel structure to be measured for positioning The position of the positioning part of the device, and measure the vertical height D from the positioning part to the steel structure; (3) measure the vertical height H and the lateral offset distance L of the positioning part of the steel structure positioning device through a total station; (4) calculate the Measure the inclination angle β of the steel structure, β=arctan(H / L); (5) Calculate the vertical height h1 from the positioning part to the center of the steel structure, h1=sinβ*D; (6) Calculate the height h of the steel structure, h =H-h1. Through this method, it is very convenient to realize the measurement of steel structures to ensure the quality of high-rise buildings.

Description

technical field [0001] The application of the present invention relates to the field of devices for measuring distance, level or orientation, and in particular to a method for measuring steel structures. Background technique [0002] With the development of the economy and the progress of society, more and more large buildings begin to appear. For these large buildings, not only are their heights getting higher and higher, but also the shapes of these buildings are becoming more and more colorful. Therefore, for the construction of these buildings The shape of the building materials is not only the current ordinary shape of the material, the shape of the material is also more and more diverse. And because of the high height of these buildings, the connection and positioning of the various materials is particularly important during construction. [0003] Steel structure is a structure composed of steel materials, which is one of the main types of building structures. The st...
