Description
Technical field
The present invention relates to a kind of arch bridge, particularly relate to a kind of bamboo wood structural system composed of bar People's Bank of China arch bridge.
Background technology
Arch bridge is a kind of common bridge form.In the long span bridge beam, generally adopt steel and/or steel concrete as the bridge construction material.But,, can adopt timber as the bridge construction material as span less pedestrian bridge or Landscape Bridge.In People's Bank of China's arch bridge, generally adopt arched girder or freely-supported crossbeam as primary structure member, the also employing barnacle arch that has is as stress system.The barnacle arch adopts more than the area of horn of plenty at some stone materials, still, because stone material is also bigger to the processing and the difficulty of construction of arch bridge stone material from great, so speed of application is slower, and constructs and need use heavy duty equipment often, and cost is higher.If adopt steel to build People's Bank of China's arch bridge, need to girder steel by designing requirement carry out in advance radian processing or the mode by assembling form arch, this is disadvantageous to industrial batch production, and its maintenance costs is also higher.For steel concrete People's Bank of China arch bridge, need formwork during construction, need form removal after the construction, not only construction is complicated, and the duration is longer.Even adopt prefabricated arched girder, its prefabricated time is also longer.For the wood arch bridge, much all adopting anticorrosion carpentery workshop is raw material, and generally all adopts arched girder as force structure.But anticorrosion carpentery workshop is a kind of deep processing timber, and its price is more expensive, and as outdoor anticorrosion wood, special control is not passed through in expanding with heat and contract with cold of himself, and deformation ratio is more serious, and is very unfavorable to the pedestrian bridge that span is big slightly, so its span is more limited.If with anticorrosion wood as the bigger pedestrian bridge of span, the prefabricated processing of its stressed arched girder with is connected comparatively difficultly, this also is one of limited reason of anticorrosion wood arch spanning degree.
Summary of the invention
It is bigger to the objective of the invention is to overcome the existing prefabricated difficulty of People's Bank of China's arch bridge, and construction is complicated, and the time is long, the primary structure member deadweight is bigger, and defectives such as not environmental protection of material provide a kind of component quality light, construction is easily simple, raw material and cheap bamboo wood structural system composed of bar People's Bank of China arch bridge.
Technical scheme of the present invention is: it comprises bridge pier, the bamboo arch ring, the bamboo bridge panel, the bamboo bridge panel support, the bamboo railing, the bamboo arch ring is by at least three bamboo arch ring laths that are arranged in parallel, connector bolt and bamboo link crossbeam and constitute, bamboo arch ring lath head and the tail connect by bolt, the middle part also connects by bolt, bamboo links crossbeam and passes gap (bamboo arch ring radian is fixed) between each bamboo arch ring lath end, each independent bamboo arch ring is coupled together, the bamboo arch ring is affixed by steel connector and bridge pier, the bamboo bridge panel support is fixed in bamboo arch ring side, on the bamboo arch ring, the bamboo bridge panel is fixed on the bamboo bridge panel support the outer side guard board of the montant of bamboo railing and bamboo arch ring by bolt.
Described bamboo bridge panel, bamboo bridge panel support, bamboo arch ring lath and bamboo link crossbeam and are made by the bamboo plywood material.
Described bamboo railing is connected by nailing with the bamboo handrail by bamboo montant, bamboo tabula and combines.
Described bamboo links crossbeam should use waterproofing materials (for example glass fabric) parcel.
Described bamboo arch ring lath also should be used waterproofing materials (for example glass fabric) parcel.
Described bamboo bridge panel should be fixed on the bamboo bridge panel support by nailing.
Described bamboo arch ring lath, except that the bamboo arch ring lath of end, the physical dimension of each bamboo arch ring lath and connecting hole position are all suitable identical, and four bolts hole of symmetry are in twos arranged on the single bamboo arch ring, so that bolt connects.
Described bamboo bridge panel support should be fixed in bamboo arch ring side by nailing, and forms cambered surface in the position that the bamboo bridge panel is installed, to make things convenient for the installation of bamboo bridge panel.
The outer side guard board of described bamboo arch ring should select for use glue bamboo (promptly gluing together bamboo wood) to make.
Bamboo wood structural system composed of bar of the present invention People's Bank of China arch bridge has the following advantages: (1) has overcome shortcomings such as bigger, the single primary structure member build of common arched girder arch bridge deadweight is big, processing or constructional difficulties, the construction period is long, horizontal thrust is bigger, can either guarantee the span of pedestrian bridge, being convenient to processing and construction again, is permanent or the fine selection of interim pedestrian bridge; (2) production and processing can realize modularization, and simple and fast is installed, and uses manpower and material resources sparingly; (3) structural safety, the moulding gracefulness is succinctly attractive in appearance, and manufacturing specification can be varied; Be convenient to adopt standardization member, standardization modulus to design and construct; (4) adopt bamboo wood as main raw material(s), its raw material sources are wide, and be renewable resource, advantages such as bamboo has fast growth, the cycle of becoming a useful person is short, output is big, China is that maximum in the world bamboo produces one of state, occupied the about 1/5 to 1/4 of world's bamboo resource, so the bamboo wood source is secure; What is more important, bamboo wood are green materials, and its manufacturing process low-carbon environment-friendly is pollution-free, meets the requirement of sustainable development.
