Problems solved by technology

Disadvantages of this measurement method: First, the installation accuracy is low
Especially when installing on windy days, the line pendant swings a lot and it is difficult to locate; 2. The installation efficiency is low
During the measurement process, the position of the center of the circle needs to be determined by three points, which is time-consuming and labor-intensive

Embodiment

[0018] Example: such as Figure 1-Figure 3 As shown, the base part is composed of a fastener 1, a base bracket 2, a foot screw 3, a base plate 4, a ball joint 5, a connecting screw 6, and a chute block 7. The structure of the fastener 1 is exactly the same as that of the scaffold fastener on the construction site, and it can rotate 360 ​​degrees at the connection with the base bracket 2 . There is a foot screw 3 between the base bracket 2 and the base plate 4, and the distance between the base bracket 2 and the base plate 4 can be adjusted by rotating the foot screw 3, so that the air bubble of the circular level 14 is centered, thereby ensuring that the base plate 4 Level. The screw rod upper end of base plate 4 bottoms has ball joint 5, can rotate 360 ​​degrees. The connecting screw 6 can move in translation along the chute block 7, and the chute block 7 is fixed on the bottom surface of the base plate 4 and can rotate around one end of the chute block 7. Tightening the c...

Abstract

The invention relates to a steel ball positioning device used for a space steel structure. The steel ball positioning device comprises a support. A positioning rod is arranged at the top end of the support, the top end coordinate of the positioning rod can be adjusted through the support, and the periphery of the positioning rod is provided with three positioning blocks which are distributed in an equilateral triangle mode; the positioning blocks are matched with screw rods in a threaded mode, the screw rods are connected with a triangular frame arranged on the support, and the positioning blocks can move along the rod shaft center lines of the screw rods; and the top ends of the screw rods are provided with tapered gears A which are engaged with tapered gears B arranged on the support. The steel ball positioning provided by the invention can improve steel ball installation precision and installation efficiency.

Description

technical field [0001] The invention relates to the construction field, in particular to a steel ball positioning device for space steel structures. Background technique [0002] Spatial grid steel structures have been widely used in long-span public buildings in recent years, such as airport terminals and gymnasiums. The space grid steel structure is composed of round steel pipes and hollow steel balls, and the round steel pipes meet at the steel balls. The space grid steel structure has the characteristics of a large number of members and nodes, and a large number of members intersecting at the same node. In order to solve the problem of multi-bar intersection connection, hollow steel balls are set at the intersection of the bars. In the construction process of space grid steel structure, the installation and positioning of steel balls is very critical, and the workload is heavy and cumbersome. The spatial positioning of the steel ball should be determined by the three-...
