Problems solved by technology

[0004] In view of the large amount of steel used in the existing steel structure network frame, the overall rigidity of the steel structure network frame is weakened. During the installation and construction process, there are high requirements for the stop position of the load-bearing scaffolding and on-site mechanical equipment, which increases the difficulty of construction. The problem of large size and reduced work efficiency, the purpose of this invention is to provide a space grid structure and its construction method, using aluminum alloy materials to make rods, which not only reduces the weight of the space grid structure, saves the amount of materials, and reduces the cost, and the structure is simpler than the traditional node structure, and the construction is more convenient

Embodiment 1

[0027] Embodiment 1: This embodiment takes the construction of the decorative grid frame on the top of an energy center building as an example, and the following is combined Figure 1 to Figure 6 Illustrate a kind of space grid structure of the present invention, it is the space grid structure that is assembled into by several grid units 10 continuously; As figure 1 and figure 2 As shown, the grid unit 10 includes several rods 11 radially distributed along its axis ax, and the converging ends of the rods 11 are fixed together by connecting plates 12, and the rods 11 are made of aluminum alloy.

[0028] Since the gas released by the energy center will corrode the traditional steel structure grid, and the long-term sun and rain will also make the traditional steel structure grid rusty, and the space grid structure of this embodiment, on the one hand, is composed of connecting plates 12 Replace the node structure of the traditional steel structure grid (welded steel plate node,...

Embodiment 2

[0036] Embodiment two: if Image 6 As shown, the difference from Embodiment 1 is that the other end of the base plate 1 of the support body 141 is provided with a connecting rod, and the connecting rod is welded on the steel column 2 of the building, so that the space grid structure can be supported on the steel column of the building. 2 on.

Embodiment 3

[0037] Example Three: Combining Figure 1 to Figure 6 Illustrate the construction method of a kind of space grid structure of the present invention, concrete steps are as follows:

[0038] 2. According to the design requirements, a number of rods 11 and connecting plates 12 are prefabricated in the factory. In order to ensure machining accuracy and improve production capacity, this embodiment adopts high-precision CNC lathes and vertical multi-axis machining centers, and is equipped with precision tools to complete the work. The cutting of the word aluminum, side plates and connecting plates 12 to ensure the processing quality and precision requirements of each component;

[0039] 2. During on-site installation and construction, it is first necessary to number each component, and correspond to and classify the design drawings one by one, so that each rod 11 in the grid unit 10 is connected to the connecting plate 12 with bolts, and the rod 11 passes through the support 14 It ...

Abstract

The invention discloses a space truss structure and a construction method thereof, and relates to the technical field of constructional engineering. The problems that an existing steel-structure truss is large in steel consumption, weak in overall rigidity, large in installation and construction difficulty and low in work efficiency are solved. The space truss structure is a space mesh structure formed by continuously splicing a plurality of truss units. Each truss unit comprises a plurality of rod pieces distributed in the axis of the truss unit in the radial direction, wherein the crossed ends of the rod pieces are fixedly connected together through a connecting plate, and each rod piece is made of aluminum alloy. The construction method includes the steps of prefabricating the rod pieces and the connecting plates in a factory, numbering all the components during site installation and construction, making the components correspond to the design drawings one to one, classifying the components, connecting all the rod pieces in the truss units with the connecting plates through bolts, supporting the rod pieces by a concrete structure or a steel column of a building through supports, and then completing splicing and fixing of the space truss structure step by step.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a space grid structure and a construction method thereof. Background technique [0002] The steel structure grid is a space system composed of many components. It has the advantages of good integrity of the space stress system, high rigidity, and good seismic performance. The basic units that constitute the grid include triangular pyramids, triangular bodies, cubes, and truncated Square cones, etc.; the grid members connect the members together through the node structure (welded steel plate nodes, welded hollow ball nodes, bolt ball nodes and welded short steel pipe nodes, etc.) to form a space shape. It varies with the form of the steel structure grid. Usually, the weight of the nodes is generally 20-25% of the total weight of the steel structure grid, and the proportion of steel occupied is relatively large. Moreover, when the building span is large, due to the...
