Problems solved by technology

However, there is a problem that the space grid structure in the prior art is complex to build, and it is difficult to adjust it once the installation is completed. When the structure needs to be fine-tuned locally, it often needs to be redesigned and built as a whole, which is very difficult.

Embodiment Construction

[0016] See attached picture. In this embodiment, taking the two-story grid structure as an example, the construction of the space grid structure is carried out through the following steps: 1) Assembling the ball-spinning adjustment support unit, the ball-spinning adjustment support unit includes steel pipe scaffolding 1, jacking 2 and The steel plate 3, the jacking 2 and the steel plate 3 are connected by bolts to form a detachable supporting platform frame. The lower end of the jacking 2 is a threaded screw 4. The working layer of the scaffold is provided with vertical and longitudinal internal threaded steel pipes, and the screw 4 is screwed into the scaffolding steel pipe Inside, the scaffolding and the jacking bracket form an adjustable movable connection; the steel plate is provided with a cylindrical support steel pipe 5 to support the ball joint; the screw rod is provided with a rotating handle 41;

Abstract

The invention discloses a building method for a space truss with a spiral ball adjusting and supporting unit. The building method comprises the following steps that (1) the spiral ball adjusting and supporting unit is assembled, the spiral ball adjusting and supporting unit comprises a steel pipe scaffold, a jacking bracket and a steel plate, the jacking bracket and the steel plate are connected to form a detachable support platform frame through bolts, the lower end of the jacking bracket is provided with a screw with a thread, the jacking bracket is screwed into a scaffold steel pipe through the screw, so that the scaffold and the jacking bracket are in adjustable movable connection, and the steel plate is provided with a cylinder support steel pipe used for supporting a sphere joint; (2) the structure of the space truss is divided into units, specifically, the whole truss structure is divided into a plurality of basic units according to actual dimension layout; (3) a ground lifting unit is formed in a spliced mode; and (4) lifting of the lifting unit is conducted. During specific work, building of the space truss is conducted according to the steps, and the spiral ball adjusting and supporting unit can adjust and control the height of the sphere joint.

Description

technical field [0001] The invention belongs to the field of construction engineering, and in particular relates to a method for building a space grid with a ball-spinning adjustable support unit. Background technique [0002] The space grid structure is a kind of space bar structure, which has the characteristics of three-dimensional force and can bear the action of all directions, and the grid structure is generally a high-order super-static structure. If a bar partially fails, only one less super-static The number of times, the internal force can be readjusted, the entire structure generally does not fail, and has a high safety reserve. The rods intersecting in the air are both stressed rods and supporting rods. They support each other and work together when working. Therefore, it has good integrity, good stability, and large space rigidity. It can effectively bear asymmetric loads. Concentrated load and dynamic load, and has better seismic performance. At the same time...
