Background technique

With the development of the economy and the progress of society, more and more large-scale buildings have begun to appear. For these large-scale buildings, not only their heights are getting higher and higher, but also the shapes of these buildings are becoming more and more colorful. 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 various materials during construction is particularly important.

Steel structure is a structure composed of steel materials and is one of the main types of building structures. The steel structure is mainly composed of steel beams, steel columns, steel trusses and other components made of section steel and steel plates. The positioning accuracy of the steel column is an important factor affecting the project quality and construction cost.

The Chinese Patent Publication No. CN105258685A discloses a steel column positioning and measuring device, which is used in conjunction with a total station.

Although the above-mentioned patent can find the center of the steel structure, it is only applicable to the steel structure in which the axis of the steel structure is perpendicular to the horizontal plane. Besides, the existing steel structure has an extra lining plate on its end face except the steel column, and the above-mentioned measuring device cannot be applied to the steel structure with the lining plate.

Utility model content

The purpose of the utility model is to provide a positioning device for a steel structure, which can position an inclined steel structure.

In order to achieve the above purpose, the basic scheme of the present invention is as follows: the positioning device of the steel structure includes a prism, a connecting rod and a connecting frame, the middle part of the connecting frame is fixedly connected with the lower end of the connecting rod, and the upper end of the connecting rod is fixedly connected with the prism, Also includes a plurality of positioning rods, the positioning rods are evenly distributed along the circumference of the connecting frame; the number of the positioning rods is at least three; each positioning rod is slidably connected to one end of the positioning rod away from the connecting frame with a positioning portion, and the end of the positioning rod A support is provided on the lower side of the part.

The working principle of this basic scheme is as follows: In this scheme, the connecting frame is fixed at the end of the steel structure, and then the support is placed at the end of the steel column, and the positioning part is slid along the positioning rod to make the positioning part and the inner lining plate. offset, and adjust the distance between the positioning part and the connecting rod. When the lengths of multiple positioning parts from the connecting rod are the same, it means that the center of the steel column is collinear with the axis of the connecting rod. By determining the position of the prism, the cylinder can be further determined. center.

The beneficial effects of adopting this basic scheme are: 1. In this scheme, the number of positioning rods is at least three and the positioning rods are evenly distributed along the circumferential direction of the connecting frame, and the positioning part on each positioning rod is used to connect with the inner wall of the lining plate If the distance between the positioning part of each positioning rod and the connecting frame is the same, it means that the center of the positioning frame is coincident with the center of the steel column.
