Abstract
The utility model relates to a triangular lattice aluminium latticed shell node, which comprises an upper node plate, a lower node plate, bar members, stainless steel screws, washers, nuts, an aluminium node cover plate, an aluminium cover plate, seal gum, seal rubber strips, aluminium press strips of the cover plate and a stainless steel tapping screw. According to design angle, a plurality of groups of holes are drilled on the upper node plate and the lower node plate which are pressed into shapes of circular arcs according to design curvature; the upper surfaces of the bar members are provided with seal grooves which are connected with the aluminium cover plate; after the aluminum cover plate matched with the grooves are embedded into the grooves, the aluminium press strips of the cover plate provided with the seal rubber strips are arranged on the bar members with grooves and fixed by stainless steel tapping screws; both sides of the aluminium press strips are sealed by the seal gum; the aluminum node cover plate is connected with the upper node plate by the stainless steel screw bolts, and the periphery of the aluminium node cover plate is fixed and sealed by the seal gum. The node forming a plate type and the straight members are connected with each other to form a single layer latticed shell with perfect curvature. The utility model has the advantages of light weight structure, corrosion resistance, high stability, and high strength. Because of the specific low temperature characteristics of aluminum products, the utility model is particularly suitable for low temperature areas.
Description
The utility model relates to the node of a kind of large-span space structure and large-scale storage tank top cover, especially triangular mesh aluminium net case node.
Along with science and technology and economy develop in depth, various longspan structure field of applications are more and more wider, use the diameter of various storage tanks also to increase day by day in petrochemical industry and other field.Common used steel design top cover exists all that weight is big, corrosion easily, construction and installation difficulty are big, cost more high weak point, particularly tank top are bearing on the very thin steel tank skin, and tank diameter is big more, and top cover weight is big more to its stability influence.
The purpose of this utility model is, a kind of triangular mesh aluminium net case node is provided, it had both possessed sufficient intensity, anti-corrosion property, leak tightness, can alleviate deadweight, convenient mounting or dismounting again, thereby can successfully be useful on the top cover of various large-span space structures and large-scale storage tank.
For realizing the purpose of above-mentioned utility model, triangular mesh aluminium net case node of the present utility model comprises: go up gusset plate, lower node plate, rod member, bolt, nut, pad and aluminium node cover plate and form.Described upper and lower gusset plate is to be the high-strength aluminium alloy plate material loading and unloading of 6061-T6 in material, form through lathe turning, drill jig boring, the angle in its boring number and every group of hole is decided according to design, upper and lower gusset plate also need strike out circular arc simultaneously, and its punching press curvature is decided according to net shell spherical diameter size; The material of described rod member is the special H-shaped material of 6061-T6 aluminum alloy, and it forms by sawing machine blanking chamfering, milling machine processing, drill jig boring, and the boring number is corresponding with upper and lower gusset plate; Described bolt is stainless steel bolt or galvanized bolt, and nut and pad adopt the material identical with bolt.
As the utility model, described rod member upper surface has the sealed groove that links to each other with the lead-covering plate, after the lead-covering plate that is complementary with groove is put into groove, the skin panel aluminium layering that sealing rubber strip is housed is packed on the reeded rod member, fix with stainless steel self tapping screw, the aluminium layering both sides seal with sealant, thereby play sealing function; Described aluminium node cover plate is to be connected with last gusset plate by stainless steel bolt or galvanized bolt, and periphery is fixing and sealing with sealant.
Adopt the utility model, this gusset-type joint links to each other with straight-bar spare and can form the perfect single-layer lattice shell structure of curvature, and its deadweight is the 1/4--1/8 of steel structure net shell, and anti-corrosion property is good, and construction and installation are simple, the efficient height.
Below in conjunction with drawings and embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is rod member of the present utility model and lead-covering plate connected structure scheme drawing.
Fig. 3 is upper and lower gusset plate boring number, angle of the present utility model and the scheme drawing that strikes out circular arc.
Can see that by Fig. 1 the utility model includes gusset plate 1, lower node plate 2, I shape rod member 3, bolt 4, pad 5, nut 6, aluminium node cover plate 7, lead-covering plate 8, corrosion-resistant steel tie bolt 9, sealant 10, sealing rubber strip 11, stainless steel self tapping screw 12, skin panel aluminium layering 13 and is connected and forms; Last gusset plate 1 is drilled with the array hole with lower node plate 2 by design point of view, and calculating according to net shell spherical diameter that punching press curvature will go up gusset plate 1 and lower node plate 2 strikes out circular arc, I shape rod member 3 upper/lower terminal faces are processed into the array boring that is complementary with last gusset plate 1, lower node plate 2; With stainless steel bolt 4, pad 5, nut 6 last gusset plate 1, lower node plate 2 are connected with I shape rod member 3 then; I shape rod member 3 upper surfaces have the sealed groove (referring to Fig. 2) that links to each other with lead-covering plate 8, lead-covering plate 8 three limits strike out the L type shape that is complementary with groove and are buckled in I shape rod member 3 grooves, sealing rubber strip 11 is contained in earlier on the skin panel aluminium layering 13, pack into together then in I shape rod member 3 grooves, fixing with stainless steel self tapping screw 12, seal with sealant 10 on skin panel aluminium layering 13 both sides again; Last aluminium node cover plate 7 is connected with last gusset plate 1 by stainless steel bolt 9, and aluminium node cover plate 7 peripheries are fixed and sealing with sealant 10, thereby make this gusset-type joint by being connected with straight-bar spare, can form the perfect single-layer lattice shell structure of curvature.
Fig. 3 is the structural representation of upper and lower gusset plate, its boring group number is decided by the design of net shell each several part, net shell centre portion rod member number is 6 bars, boring group number just is 6 groups, marginal portion rod member number is 5 bars, boring progression just is 5 groups, and line of centers angle angle 1, angle 2, angle 3, angle 4, angle 5, the angle 6 in every group of hole are to be decided by design; And upper and lower gusset plate also need strike out circular arc, and its punching press curvature is decided according to net shell spherical diameter size, and promptly net shell spherical diameter is big, and its punching press curvature is just little, otherwise net shell diameter is little, and its punching press curvature is just big.
The utility model uses mounting tools commonly used in installation process, convenient and simple, and the design considerations relative national standards standard of net shell, and good reliability is made the more external similar engineering of cost of installation and reduced at double.
