Description
Technical field
The present invention relates to a kind of bamboo wood building, more particularly to a kind of main structure sphere net suitable for Long Span Roof Structures
Structure type, node connection and its installation method of shell.
Background technology
At present, the main material of Building Trade in China is based on concrete and steel, and either the prefabricated processing of steel construction is also
It is pouring for concrete structure, belongs to the industry of high pollution, highly energy-consuming, and does not meet the target of national sustainable development.
In this year, with the proposition of green building theory, green building is increasingly subject to social extensive concern.It is light-duty in recent years
Timber structure is increasingly favored by people, however, China's Forest Resources are very deficient, and trees cycle of becoming a useful person is longer, thus
Construction timber is very limited, and the unfavorable exploitation of production line, therefore, it is difficult to widely popularize light-duty wooden.And simultaneously, the bamboo wood in China
Resource is very abundant.Becoming a useful person, the cycle is short, bamboo wood fertility is strong, tension, compressive property are strong, can be that a large amount of construction of bamboo structure carry
For the raw material of abundance.To sum up, bamboo wood is developed and utilized, it is to realize building environmental protection that bamboo wood is widely used in into building structure field
Green, the requisite measure for ensureing social sustainable development.
Bamboo wood building it is long-standing with the topic of sustainable development, bamboo wood has many good qualities, as it is in light weight, solid, have it is tough
Property, it is a very environmentally friendly construction material, bamboo wood building has the unrivaled superiority of other building materials：
1 resource is renewable.Bamboo wood is a kind of fabulous renewable resource, can forever continue and use again.Bamboo wood possesses growth cycle
It hurry up, yield high-performance.
2 environment-friendly products are pollution-free.Bamboo wood is extremely important member to the balance of oxygen and carbon dioxide in large natural environment
Element, carbon sequestration capacity are strong.As construction material, masonry, coagulation great soil group are far smaller than in terms of energy consumption, pollution during construction
Building, it is good green material.
3 tensions, resistance to compression.Bamboo has very high intensity, and tensile strength is 2 times of steel, and compression strength is concrete
2 times.
4 shock resistances are strong.Due to light weight, elasticity is good, and the function of seismic resistance of bamboo is very prominent, even in strong ground
Earthquake centre overall structure deforms, and also will not fall apart or collapse.
5 traditional ＆ are modern to be combined.Bamboo wood building is reasonable application of the conventional art in modern building design, when having complied with
The trend in generation.
However, the bamboo structure in engineering is mainly based on the less structure of span, but be difficult in some special forms at present
Used in the space structure such as reticulated shell of formula.And in some public buildings（Such as cinema, large-scale meeting-place, exhibition center）,
The space form of large span has larger demand.
The content of the invention
The present invention is in view of the above-mentioned problems, propose a kind of structure type and method of bamboo rib-ring-shaped sphere net case.
To achieve the above object, the technical scheme is that：A kind of bamboo rib-ring-shaped sphere net case, it is rib-ring-shaped by top

The multiple broadwise annular construction members of secondary connection, purlin is connected in the radial bars between two layers of broadwise annular construction member and forms purlin ring, broadwise
Connected by steel node between bar, between radial bars and broadwise bar, be bolted between purlin and radial bars respectively；It is described
Lowermost strut system includes one and links annular construction member by laterally linking the transverse direction that is formed of bar head and the tail, supports in more Y types, more
Y types lower supporting rod, more vertical supportings, multiple steel nodes；The vertical supporting passes through on outermost broadwise bar annular construction member
Steel node is connected with the rib-ring-shaped sphere bamboo net in top, in Y types support by the broadwise burr of two layers of outermost to the steel section on component
Point is connected with the rib-ring-shaped sphere bamboo net in top, is supported in Y types and connects Y types lower supporting rod by steel node and laterally link bar, perpendicular
It is connected to support and Y types lower supporting rod by steel node with concrete foundation；The radial bars, broadwise bar, purlin, vertical supporting, Y
Strut, Y types lower supporting rod, the horizontal mao bamboon bar for linking bar and being treated using passing through in type.
The steel node is divided into：Centroid, internal layer annular component node, intermediate layer annular construction member node, outer annular
Component node, Y types support node, V-type base node；The Centroid connects all radial bars；The internal layer annular construction member
Node, intermediate layer annular construction member node, outer annular component node are pre-manufactured steel node.
The quantity of the radial bars of the rib-ring-shaped sphere bamboo net in top in the Y types in lowermost strut system with supporting, under Y types
The quantity of strut is identical.
The quantity of broadwise bar in each broadwise annular construction member of the rib-ring-shaped sphere bamboo net in top and lowermost strut body
The lateral ties bar quantity of system is identical.
A kind of preparation method of mao bamboon bar for bamboo rib-ring-shaped sphere net case, it is characterised in that：
1）Processing early stage of mao bamboon bar：When the juice sugar content of mao bamboon cane is relatively low, bamboo wood is gathered in cutter, by mao bamboon
Sub- end is whittled into inclined plane shape, prevents that rainwater from entering and rhizome lower caustically, by the time of sub- drying 2-3 weeks of mao bamboon, for filtering
Except sugar remaining in juice, preservative treatment then is carried out to bamboo wood, culm bar is erected in wooden barrel, from top to bottom by barrier film
Perforation, from top to penultimate ring, is subsequently poured into impregnating fluid, after the completion of, by last septal perforator, and collect residual
Remaining liquid；
2）Make mao bamboon bar：Installation mao bamboon boom end connector, pre-buried otic placode at mao bamboon bar both ends, and three steel bushings are set

Year, and the term of validity for passing through the bamboo wood safeguarded is 10 years or so.
Rib-ring-shaped network structure in the present invention is the primary structure part of the force of space structure, in vertical load or ought be held
When by evenly loads such as wind loads, radial direction rod member bears larger pressure, and most of load is transferred into Y type branch by node
Support and vertical supporting.Purlin and ring rod member are then rib-ring-shaped sphere net case to being formed radially the lateral support of Dual Stabilization
Globality provides good ring Confinement effect.When wind load is born, radial direction bamboo bar tension, and ring rod member, purlin
Pressure suffered by bar then forms stable clossing pressure ring, and belt tie-rod also form one layer of clossing pressure ring, be advantageous to prevent
Structure is started by wind suction and causes to destroy.
