Abstract
The utility model discloses a linked square reticulated single-layer arched reticulated shell roof structure. Multiple groups of box type double-curvature arches in two different directions are connected crosswise and are waved into a reticulated shape. The roof structure is characterized by being formed by assembling X-shaped notes (1), Y-shaped nodes (2) and box type inclined rods (3). The utility model further discloses a manufacturing method of the linked square reticulated single-layer arched reticulated shell roof structure. On the premise that structural requirements are met, the roof structure is convenient to process.
Description
Technical field
The utility model relates to a kind of roofing steel work, is specifically related to a kind of lamella type individual layer arch net shell roof structure.
Background technology
Bent member is of common occurrence in the engineering of large-scale emphasis, and the new airport of bearing with our company in National Stadium and Kunming is representative especially, and feature big, thick, that turn round runs through whole member, and its cross section is box section.Whole arch covering net shell is formed by the box double curvature arch braiding of many groups of two different directions, because of roofing adopts the single layer structure form, each arch intersects to form the lamella shape mutually, in addition because the arch direction is oblique layout, to guarantee the upper and lower plane rounding off (i.e. two arc surfaces) that encircles simultaneously, therefore the box section of each single arch has formed irregular diamond-shaped cross-section form, and is variable section structure; In addition because the node of requirement in the middle part, two ends of arch covering of building is two-way, therefore bring a bigger difficult problem to processing.Which kind of mode roofing adopts carry out segmentation, and whether the segmentation posterior nodal point satisfies the factory process requirement, and how joint form is formulated, and can segmentation satisfy transportation and site operation lifting requirements, and these all are the difficult points of this engineering.
The utility model content
The utility model purpose: the purpose of this utility model is at the deficiencies in the prior art, and a kind of lamella type individual layer arch net shell roof structure easy to process is provided.
Technical scheme: lamella type individual layer arch net shell roof structure described in the utility model, intersect by the box double curvature arch of many groups of two different directions and to link to each other, be woven into nettedly, described roof structure is assembled by X-shaped node, Y shape node and box brace.
The cross section of described X-shaped node, Y shape node and box brace is irregular rhombus, and mouthful variable cross-section that 3000*1000*16 (30)～mouth 2000*1000*16 (30) does not wait is adopted in the cross section, and curved.
In the utility model, utility model people is according to this engineering structures form, satisfying under the prerequisite of code requirement, take all factors into consideration under the condition of factors such as on-site hoisting, member transportation, factory-assembled, technician's combination experience of similar engineering is in the past carried out the analysis-by-synthesis comparison and is expounded through peer review, determine at last X-shaped node, Y shape node and box brace are adopted in this roofing segmentation, segmentation can either be satisfied the requirement of above two aspects like this, also can satisfy designing requirements such as structure and architectural appearance simultaneously.
The preparation method of lamella type individual layer arch net shell roof structure described in the utility model comprises the steps:
(1) adopt computer software that X-shaped node, Y shape node and each member of box brace are carried out setting-out respectively, adopt digital controlling plasma to cut;
(2) form that the member sample is combined with the steel moulding bed is carried out Integrated Checkout;
(3) from block mold single node is taken out one by one, carry out the secondary in-depth, repaint the moulding bed that is suitable for the workshop processing and fabricating separately, so not only improved the precision of making, processing and fabricating efficient also is greatly improved simultaneously; Adopt ground sample method and total powerstation comprehensive detection when detecting in addition, to guarantee the making precision of member;
(4) on the basis that guarantees the single-piece precision, adopt the computer simulation assembling method, whole roofing grid is carried out the regression analysis and the detection of member, improved on-the-spot lifting precision so greatly, solved the limitation of effects limit such as the preframed place of entity.
For avoiding splicing the trueness error of bringing, in the step (1), each member is taked whole blanking, carry out Numerical control cutting between the groove of end face during blanking, to guarantee whole machining accuracy.
Beneficial effect: the utility model compared with prior art, its beneficial effect is: 1, the utility model product is guaranteeing to be convenient to processing under the prerequisite of structural requirement; 2, the utility model method machining accuracy height satisfies the use and the appearance requirement of monolithic architecture.

The specific embodiment
Below in conjunction with accompanying drawing, technical solutions of the utility model are elaborated, but protection domain of the present utility model is not limited to described embodiment.
Certain house-owner of railway terminal main website body structure is rail layer structure, high rack-layer structure, overhead auxilliary building structure and arch covering structure from down to up, totally five layers.Floor height is respectively 9.5m, 12.5m, 5m, 5m, 37m, overall height 69m from bottom to top.Arch covering is a lamella type single-layer lattice shell, and overhead auxilliary building steel frame is as the bearing of arch covering structure and main lateral resistant member.
Wherein roofing adopts the braiding of diamond-shaped cross-section steel member to form, and forms a curved grid arch, this kind form of structure, and each member is all linked with one another, and the required precision that mutual related size is controlled when processing and fabricating is high especially.
Form of structure according to this engineering, the utility model lamella type individual layer arch net shell roof structure, specific constructive form as shown in Figure 1, box double curvature arch by many groups of two different directions intersects continuous, be woven into netted, described roof structure is assembled by X-shaped node 1, Y shape node 2 and box brace 3, and the cross section of X-shaped node, Y shape node and box brace is irregular rhombus.
The preparation method of lamella type individual layer arch net shell roof structure described in the utility model comprises the steps:
(1) adopt computer software that X-shaped node, Y shape node and each member of box brace are carried out setting-out respectively; Each member is taked whole blanking, carry out Numerical control cutting between the groove of end face during blanking;
(2) form that the member sample is combined with the steel moulding bed is carried out Integrated Checkout;
(3) from block mold, single node is taken out one by one, carry out the secondary in-depth, repaint the moulding bed that is suitable for the workshop processing and fabricating separately; Simultaneously single node component is carried out comprehensive detection;
(4) adopt the computer simulation assembling method, whole roofing grid is carried out the regression analysis and the detection of member.
As mentioned above, although represented and explained the utility model that with reference to specific preferred embodiment it shall not be construed as the restriction to the utility model self.Under the spirit and scope prerequisite of the present utility model that does not break away from the claims definition, can make various variations in the form and details to it.
