detailed description

The structure and technical effects to be achieved of the present invention will be described below with specific embodiments in conjunction with the accompanying drawings, but the selected embodiments are only for illustration and explanation, and are not intended to limit the scope of the present invention.

As shown in FIG. 1 , the present invention provides an assembled oblique triangular folding special-shaped aluminum plate molding system, which includes a keel structure 1 , several aluminum plate structures 2 and a transition structure 3 between them.

As shown in Figure 2 and Figure 3, the keel structure 1 is located on the outdoor side of the building, including a number of vertical supporting corbels (not shown in the figure, which are existing structures), corresponding to the horizontal span of the building, and the adjacent supporting corbels Several transverse keels 11 are arranged between the legs, and square links are adopted in the present embodiment. Preferably, in order to achieve a slender cross-section of the large-span transverse keels 11, adjacent transverse keels 11 are connected by vertical suspenders 12, and threaded sleeves 13 are provided on the top and bottom surfaces of the transverse keels 11 to connect the suspenders 12. The uppermost suspender 12 is connected to the steel beam at the top of the building, and the lowermost suspender 12 is connected to the steel beam at the bottom of the building. The suspender + horizontal large-span transverse keel support force system reasonably solves the requirements of structural force and architectural effect, and the suspender 12 effectively transfers the vertical load from bottom to top to the upper main structural beam. The boom 12 can effectively control the vertical deformation of the large-span transverse keel 11, and the large-span transverse keel 11 only needs to resist the load in the horizontal direction, so that the cross-section of the transverse keel 11 can be small in the vertical direction, and the horizontal dimension can be determined according to its span Determined with the size of the horizontal load, the flat cross section of the transverse keel 11 can effectively meet the slender architectural visual effect. The threaded sleeve 13 and the horizontal large-span transverse keel 11 are fixed with locking gaskets. There is a through hole on the keel corresponding to the position of the threaded sleeve 13. The diameter of the through hole is larger than that of the threaded sleeve 13. On the one hand, in order to absorb the deviation of the opening On the other hand, it can effectively alleviate the problem that the horizontal deformation of the large-span transverse keel 11 causes the suspender 1 to be bent. Open vertical slots on the connecting lug plate at the bottom of the suspender 12 to adapt to the vertical deformation of the upper main structure beam and avoid the failure of the suspender 12 under pressure. The horizontal large-span transverse keel 11 resists the load in the horizontal direction, and the large through-hole structure on the transverse keel 11 corresponding to the position of the threaded sleeve 13 of the suspender 12 can effectively alleviate the bending problem of the suspender 12 . The boom 12 is installed from top to bottom, relying on the boom 12 to hang the horizontal large-span transverse keel 11 to control the vertical deformation. The suspender + steel keel supports the steel structure system with reasonable force, safe and reliable, convenient installation, and transparent architectural effect.

After the upper and lower hyperbolic aluminum plates are twisted and formed, they are welded and spliced along the joints of the upper and lower aluminum plates. The lower aluminum plate 26 is welded and formed, and the triangular folded aluminum plate structure is finished. Since the upper aluminum plate 25, the lower aluminum plate 26 and the sealing plate 27 form a whole, the aluminum plates support each other and form a strong rigidity to resist external loads. The triangular folded aluminum plate structure itself does not need keel support to achieve a large span The effect of the folded triangular aluminum plate structure on the facade can also be made into an inclined shape to achieve the effect of enriching the building facade.
