Description
Technical field
The invention belongs to Structural Engineering field in the middle of civil engineering, relate to a kind of novel bamboo Cable Structure unit.
Background technology
Bamboo structure is applied more and more wider in the middle of present building, and many small-sized buildings are built by bamboo structure.Bamboo structure has environmental protection, and lightweight has stronger axial push-pull mechanical property simultaneously, so in some provisional buildings, or in the middle of more small-sized building, Application comparison is extensive.Simultaneously the mode of construction of Bamboo structural building is also fairly simple, and the concrete that node processing is relatively common and steel work are also easily a lot, and this construction speed making bamboo structure small building is also than comparatively fast.
Apply more widely although Bamboo structural building has had, but its application is still limited in the middle of more small-sized temporary building at present, seldom have the Bamboo structural building that span is larger, very large reason is that can be applied in the middle of the larger structure of span large across supporting member because the feature of bamboo wood itself is difficult to make.The dome in the India shop in the middle of World Expo makes of bamboo wood, and its establishment utilizing bamboo wood mutual defines large across bamboo structure, but way is cumbersome, does not have applicability widely.So it is very important to design a kind of bamboo structure bearing carrier that the range of application of bamboo structure can be made to be extended in the middle of the larger building of span newly.
Summary of the invention
The object of the invention is to the defect for overcoming prior art and provide a kind of novel bamboo Cable Structure unit, this element can be used in larger load-bearing place of Bamboo structural building span, and bamboo wood can be applied in relatively large building.
For achieving the above object, the present invention is by the following technical solutions:
In order to meet the requirement of large span, and give full play to the rift grain Anti-pull-press performance of bamboo wood, bamboo wood is curved arcuation, if span is excessive, can connector be utilized to couple together according to the curved good bamboo bar of curvature on multistage bamboo bar, form a complete arch.Wherein the connection of two sections of bamboo bars inserts bending steel beam column in the middle of adopting, and stamps pin in bamboo bar junction symmetry, through steel beam column, is used for fixing steel beam column at junction joints cement mortar simultaneously.In order to resist the horizontal thrust at bamboo arch bipod place, in the middle of bipod, use cable wire drawknot.Steel bushing part is enclosed within the pin of bamboo arch, and inner joints cement mortar, cable wire is anchored on steel beam column.The present invention mainly utilizes the Anti-pull-press ability of former bamboo, utilizes connector to make the arch structure of large span former bamboo, and utilizes cable wire drawknot to make it form the bamboo cable elements of self-balancing at bipod place.This element can much use by Pin, jointly as the skeleton of large span architecture dome.
A kind of bamboo Cable Structure unit that the present invention proposes, comprises bamboo bar, cable wire, cement mortar, the first steel beam column, the second steel beam column, steel pin nail and ground tackle, wherein: described multistage bamboo bar span as requested, curves suitable curvature; The junction, end of two sections of adjacent bamboo bars is inserted at the two ends of the first steel beam column respectively, and the junction, end of two sections of bamboo bars and the first steel beam column are followed closely fixing by steel pin, and the junction of the junction inwall of two sections of bamboo bars and the first steel beam column is fixed by cement mortar; Multistage bamboo bar connects and composes arch bamboo bar successively; On the bamboo arch springing of arch bamboo bar, cover has the second steel beam column, and the bamboo arch springing of arch bamboo bar and the second steel beam column junction are fixed by cement mortar, and connected by cable wire between two bamboo arch springings of arch bamboo bar, described cable wire is fixed on bamboo arch springing by ground tackle.
In the present invention, described first steel beam column is two sections of adjacent bamboo bars curve suitable curvature steel pipe in the flexibility of junction.
In the present invention, the junction, end of described first steel beam column and bamboo bar is reserved with pin hole.
In the present invention, described steel pin nail is from top to bottom successively through the reserved pin hole on the pin hole of the junction, end of bamboo bar and the first steel beam column, the reserved pin hole of the opposite side connected everywhere from the end of bamboo bar again passes, and described steel pin nail is arranged vertically with bamboo bar and the first steel beam column.
In the present invention, described second steel beam column is steel bushing part.
According to span needs, determine the shape that bamboo is encircleed and concrete size.Bamboo bar is curved required shape, and the first steel beam column diameter being less than bamboo bar stretches into bamboo bar depths, avoids contacting with ring place, and plugs steel pin nail and fixed by the first steel beam column, two sections of bamboo bars is connected.In order to fix the first steel beam column better, by joints cement mortar in the bamboo bar of junction.Thus form intactly bamboo arch.
Second steel beam column and steel bushing are enclosed within two arch springing places, then utilize ground tackle to fix cable wire, finally joints cement mortar in the second steel beam column is used for fixing bamboo arch, thus forms intactly bamboo Cable Structure unit.
The present invention has following beneficial effect:
As the dome frame member of large-span structure, roof truss members can be similar to and be applied in the middle of the larger Bamboo structural building of span, expanded the range of application of Bamboo structural building.
