Problems solved by technology

The connection of the space pipe truss is basically fully welded, so that there are intersecting openings between the pipes. Due to the irregularity of the space truss, the intersecting openings are also intricate and intersecting, which brings about the intersecting openings of the pipe trusses. The problem of difficult positioning

Embodiment Construction

[0019] Below in conjunction with specific embodiment, further illustrate the present invention. It should be understood that these examples are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the teachings of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of the present application.

[0020] Such as Figures 1 to 3 As shown, a method for locating intersecting openings of pipe trusses includes a horizontal frame 4, a semi-cylindrical gauge block 2 and an inclinometer 3. The horizontal frame 4 is equipped with a cam 5, and the cams 5 at both ends are parallel to each other. The semi-cylindrical gauge block 2 is a half-cylinder that is equally divided along the axis, the upper and lower semicircular surfaces o...

Abstract

The invention relates to a method for positioning a through hole of a pipe truss. The method comprises a horizontal frame, a semi-cylindrical gauge block and an inclinometer, wherein the semi-cylindrical gauge block is a semi cylinder which is uniformly distributed along an axis, the upper semi-round surface and the lower semi-round surface of the semi-cylindrical gauge block are vertical to an equipartition surface, and the radius of the protruded semi cylinder of the semi-cylindrical gauge block is matched with the curve of a through hole of a pipe truss chord member. The method comprises the following steps that the pipe truss chord member is installed on the horizontal frame and is fixed; the semi-cylindrical gauge block is clamped in the through hole of the pipe truss chord member; the inclinometer is used to measure the inclination angles of the axial equipartition surface and two semi-round surfaces of the semi-cylindrical gauge block; the pipe truss chord member is adjusted to the required position and is welded with a pipe truss base rod into a whole; and the previous steps are repeated, and all the pipe truss chord members are welded on the pipe truss base rod. The method has the advantages that the splicing precision of the through hole of the pipe truss is increased, the relative processes for positioning the through hole of the pipe truss are reduced, the speed for positioning the through hole of the pipe truss is increased, and the accuracy for positioning the through hole of the pipe truss is ensured.

Description

technical field [0001] The invention belongs to the technical field of intersecting opening measurement of pipe trusses, in particular to a positioning method for intersecting openings of pipe trusses. Background technique [0002] The space tube truss structure has the advantages of light weight, high rigidity, stable structure, good seismic performance, beautiful appearance, flexible installation methods, and easy to improve the processing and installation quality of components. In recent years, it has developed rapidly in the fields of civil and commercial construction in my country. Fast, they are widely used in the roof structure of various buildings, such as: stations, airports, stadiums and so on. The connection of the space pipe truss is basically fully welded, so that there are intersecting openings between the pipes. Due to the irregularity of the space truss, the intersecting openings are also intricate and intersecting, which brings about the intersecting openings...
