For realizing the rapid construction of individual layer spatial mesh structure, the present invention proposes one and to be threaded individual layer spatial mesh structure.This System structure is simple, easy construction, and bearing capacity is reliable, can improve the economy of structure.Concrete technical scheme is as follows:
One is threaded individual layer spatial mesh structure, comprises elementary cell (1), connecting rod (2) and tapped sleeve (3); Described elementary cell (1) is welded by solder sphere (4) and multiple long thread segment joint (5); Described connecting rod (2) comprises tubular rod segments (7) and short thread segments joint (6), tubular rod segments (7) two ends respectively with short thread segments joint (6) adopt welding manner to be fixedly connected with without the end of thread; Upper to short thread segments joint (6) in connecting rod (2) and elementary cell (1) long thread segment joint (5) is connected by internal thread by sleeve (3).
Described elementary cell (1) has the joint of varying number and different directions according to design in advance, and described solder sphere (4) adopts welding manner to be fixedly connected with long thread segment joint (5) without the end of thread.
Described long thread segment joint (5) forms external screw thread by machining, short thread segments joint (6) forms tooth form by machining, pitch is identical, depth is the external screw thread of long thread segment joint (5) half, sleeve (3) is formed and the identical tooth form of long thread segment joint (5), internal thread that pitch is identical with depth by machining, long thread segment joint (5) is connected by sleeve (3) with short thread segments joint (6), after connection, sleeve mean allocation is on two joints.
Be threaded have power transmission reliable, easy to process, dismantle simple feature, for structure Fast Installation provides technical foundation.
Difform assembled unit can be formed by the connection of multiple different elementary cell, and then easily extensible or be assembled into difform individual layer spatial mesh structure, as Single-Layer Cylindrical Reticulated Shell Structures and Reticulated Domes etc.
The described assembling spatial mesh structure that is threaded, is fixed in lower support structure by support node.Support node can select the spatial mesh structures such as arching pressure bearing to commonly use bearing.
Beneficial effect
The invention has the beneficial effects as follows by being connected threaded joint in solder sphere end with Rod end, welding during script site operation being changed into and is threaded easily, effectively improve the efficiency of construction, shorten construction period, reduce construction cost; It, by prefabrication production and processing, improves precision and the quality of welding effectively.This structure is specially adapted to all types of individual layer spatial mesh structure systems of middle-size and small-size span, as Single-Layer Cylindrical Reticulated Shell Structures and Reticulated Domes etc.

Specific implementation method
Below in conjunction with Fig. 1, Fig. 2 two difform embodiments, in conjunction with its design, processing and installation process, structure of the present invention is described.
Embodiment one:
By the mode of machining after machining or first casting, each component of processing the present invention.For ensureing precision, each component can adopt machining, or casting and the mode that combines of machining are carried out.In addition, weld in factory, can product quality be ensured.
As shown in Figure 1, in the present embodiment, elementary cell (1) has two kinds of structures according to actual needs, a kind of is elementary cell in the middle part of structure, it is provided with the joint in 12 directions, another kind is the joint that the joint of structure periphery is provided with 4 directions, and concrete number and direction can adjust to some extent according to actual conditions.The joint in each direction of the elementary cell in the middle part of structure is all connected with the joint of a structure periphery with sleeve (3) by connecting rod (2), the joint of 12 structure peripheries is connected with sleeve (3) by connecting rod (2) each other, forms a umbrella-shaped structure thus.
Be fixedly connected by welding between solder sphere (4) and long thread segment joint (5), the structure of elementary cell as shown in Figure 3.
The industry such as all machining of the present invention, welding all can be prefabricated in the factory, and reduce job site workload, shorten construction period.
Under concrete installation steps enter:
Tapped sleeve (3) is screwed onto completely on the corresponding long thread segment joint (5) of elementary cell (1), as shown in Figure 5.
