One extension bar 2 and two outsides of the seam of cross node 1, bolt 4 pass through the first lifting hole(eyelet) 31, extension bar 2 and the cross node of connecting tile 3
1 bolt hole 11 is connected, and connecting angle iron 5 is on the connecting seat 12 of extension bar 2 and through bolt connection;
Described cross node 1 and the bolt hole 11 of the rod end head of extension bar 2 are several, and are equidistantly positioned;Described company
It is several right to connect the first lifting hole(eyelet) 31 on the panel of tile 3, is arranged and is equidistantly positioned in "eight" shape to both sides with the center of plate length.
Embodiment:
Refering to Fig. 1, Fig. 2, Fig. 3, the present invention is used for building curved surface external decoration, and the present invention is with cross node 1, extension bar 2, company
Tile 3 and bolt 4 are connect as bare bones, the lattice framework of curved surface is built into building surface, then will by connecting angle iron 5
Shell decoration panel is mounted on framework, realizes the profile decoration of building curved surface, below by taking present invention application as an example, further
It is described as follows:
The production of parts:
Refering to Fig. 1, Fig. 2, first, the construction drawing of lattice framework is designed according to outside vertical surface of building, is determined by construction drawing
The coordinate position of each cross node 1 of external surface of buildings, and determine by the curved surface of each place coordinate position of cross node 1 short
The axis co-planar of cylindrical bar is non-coplanar, and non-coplanar cross node 1 is determined radial short circle as the curved surface where the node
The radiation angle of mast, produces cross node 1 by construction drawing and marks coordinate position, configure the extension bar 2 of different length, and produce
General connecting tile 3, bolt 4 and connecting angle iron 5 supplies assembled in situ;
The installation of job site:
Refering to Fig. 1, Fig. 2, Fig. 3, corresponding cross node 1 is installed in the node coordinate position marked by construction drawing, selection with
The extension bar 2 configured between adjacent two crosses node 1, the two of cross node 1 and the seam of extension bar 2 are wrapped in two panels connecting tile 3
Outside, is connected, then use with the bolt hole 11 of bolt 4 through the first lifting hole(eyelet) 31, extension bar 2 and cross node 1 of connecting tile 3
Bolt, by connecting seat 12 of the connecting angle iron 5 loaded on extension bar 2, completes the installation of extension bar 2, i.e., one by one successively through the second lifting hole(eyelet) 51
Complete building for building surface curved surface lattice framework;Shell decoration panel is mounted on framework again, and passes through bolt
Shell decoration panel is connected with connecting angle iron 5, finally, the bolt position on connecting angle iron 5 is adjusted by the second lifting hole(eyelet) 51, really
Shell decoration panel is determined in the exact position of lattice framework, realizes decoration of the shell decoration panel in building positive camber.
Refering to Fig. 1, Fig. 2, because the cross node 1 of the present invention is arranged radially for short cylindrical bar, its short cylindrical bar
Axis is parallel with the tangent line of the Focal point building thing surface curve, beneficial to the big complex-curved lattice structure of many flex points, Curvature varying
Frame is built, and curved surface is precisely proper, flex point transitions smooth, with it is simple in construction, shape accurate, easy to adjust, installation effectiveness
The advantage of high and live welding construction.
Refering to Fig. 1, Fig. 2, connecting tile 3 of the invention is the straight panel of arc section, and its panel is provided with the first lifting hole(eyelet) 31,
And lifting hole(eyelet) 31 is several right, arranged with the center of plate length to both sides in "eight" shape and with the bolt hole 11 of extension bar 2 and cross node 1
Correspondence is equidistantly positioned;When two panels connecting tile 3 is wrapped in cross node 1 and two outsides of the seam of extension bar 2, passed through with bolt 4
During the bolt hole 11 of the first lifting hole(eyelet) 31 of connecting tile 3, extension bar 2 and cross node 1, only connection need to be rotated around the axis of extension bar 2
Tile 3, the first lifting hole(eyelet) 31 arranged in "eight" shape can change relative to the position of the bolt hole 11 of extension bar 2 and cross node 1
Become, be easy to wearing for bolt 4 to connect and install;After 4 pretension of bolt on connecting tile 3, extension bar 2 and cross node 1, with special
Torsion spanner, the axis around extension bar 2 rotates connecting tile 3, the effect of the side pressure bolt 4 of the first lifting hole(eyelet) 31 arranged in "eight" shape
Under, you can reach and the axial seam between cross node 1 and extension bar 2 is got rid of to tight purpose.
