Problems solved by technology

Otherwise, the requirements of the building size cannot be guaranteed; at the same time, if the deviation is too large, the intersecting openings of the rods connected to it will not be able to fit, which will affect the construction.
[0007] The drum-shaped welding ball is a partially flattened closed sphere with a smooth surface, lack of measurement reference points, difficult positioning, and low installation efficiency

Embodiment Construction

[0038] according to figure 1 As shown, the drum-shaped welding ball 1 is welded together by a drum-shaped shell 2 and a hemispherical shell 3 . combine Figure 2~5 As shown, the preferred embodiments of the present invention are further described in detail.

[0039] The first step is to level the site and lay steel plates 5 for assembling;

[0040] The second step is to adjust the assembly posture of the unit on the CAD model, provide the coordinates of the center of the welding sphere 10 and the relative height difference 11, and provide the coordinates of the measurement control point 15 of the drum surface 4;

[0041] In the third step, according to the coordinates of the center of sphere coordinates 10 and the coordinates of the measurement control point 15 of the drum-shaped surface 4, utilize the measuring instrument to release the coordinates of the center of the sphere projection point 6 and the coordinates of the measurement control projection point of the drum-shap...

Abstract

The invention belongs to the technical field of steel structures, and particularly relates to a steel structural drum-shaped welding ball positioning regulating method. The steel structural drum-shaped welding ball positioning regulating method comprises the following steps: firstly, drawing a cross curve on a drum-shaped surface of a welding ball by taking the circle centre of the drum-shaped surface as a central point, and making a mark at the position which is away from the centre of the cross curve by a certain fixed value to serve as a measurement control positioning point of the drum-shaped surface; secondly, projecting a given measurement control projection point on a steel plate on the ground by utilizing a measurement instrument; thirdly, determining the supporting height of a steel pipe, and hoisting and placing the welding ball in place; and fourthly, regulating a ball body to determine the drum-shaped surface by utilizing the tools, such as angular steel, a line hammer and a horizontal guiding rule; and the steel structural drum-shaped welding ball positioning regulating method has the beneficial effects that the positioning regulating method is accurate and reliable, and the assembling precision is ensured.

Description

technical field [0001] The invention belongs to the technical field of steel structures, and in particular relates to a method for adjusting the positioning of drum-shaped welding balls in steel structures, mainly aiming at the installation and positioning of drum-shaped welding balls in space steel structures. Background technique [0002] In the field of building steel structures, when the number of joints at the joints is large, the welding ball connection method is often used instead of the pipe-pipe intersecting welding form. [0003] The shape of the welding ball is a smooth sphere. For the upper and lower chord positions of the roof, sometimes the outline of the sphere exceeds the outer skin of the building. In order to meet the requirements of building size and building energy efficiency, it is necessary to reduce the thickness between the upper and lower skins of the roof structure. [0004] Without affecting the safety of the structure, one of the ways to reduce t...
