Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0030] like Figure 1-14 Shown: a combined network frame 3, including upper chords, diagonal webs, lower chords and gusset plates. The quadrangular pyramidal space grid formed by the combination of the upper chord, the oblique web and the lower chord, the upper chord, the oblique web and the lower chord are connected by gusset plates; the upper chord and the oblique web are compression-resistant Rods 2 made of good materials, the lower chords are pipes 1 with good tensile properties;

[0031] Depending on the position of the upper chord, the opening position and length are also different.

[0032] The gusset plate with the upper chord of the grid in the middle (that is, the gusset plate connecting the 4 upper chord bars) is the upper chord gusset plate a 5 and the upper chord gusset plate d 8; ) is the upper chord gusset plate b 6 and the up...

Abstract

The invention discloses a combined net rack and belongs to the technical field of building combined structures. The net rack is a quadrangular pyramid spatial net rack formed by combining tubes with high tension resistance with members made from other materials with high pressure resistance. Lower chord members are made from the tubes, upper chord members and web members are formed by the members made from the other materials, and all the members are connected through plate-type joints. Supports are arranged in the proper positions of the lower portions of lower chord joint plates, so that the whole structure is fixed to supporting structures. The net rack is suitable for square or rectangular structures such as roofs and canopies. Compared with net racks of traditional steel structures, the net rack has the advantages of being small in steel consumption, low in self weight, simple in structure, convenient to manufacture and mount, low in cost, good in mechanical performance and the like.

Description

technical field [0001] The invention relates to a new type of quadrangular pyramid space combined grid structure used as a roof or canopy, especially a space grid structure composed of pipes with superior tensile strength and rods with better compression resistance , belongs to the technical field of building composite structures. Background technique [0002] At present, the known grid structure is to combine a lot of rods according to a certain combination rule through node connections to form a flat mesh space rod system structure. The member on the upper plane is called the upper chord, the member on the lower plane is called the lower chord, and the member connecting the upper and lower nodes is called the diagonal member. The nodes of the grid structure are generally considered as hinged nodes. The rods mainly bear the axial tensile pressure, and the cross-sectional size is relatively small; the rods support each other, so that the stressed rods and the support system...
