Description
Technical field
The present invention relates to structural engineering technical field, be specially a kind of board plug type band enhancement mode wooden construction Tenon node.
Background technology
China's timber buildings is with a long history, and there is distribution all parts of the country, and timber buildings accounts for more than 50% of whole ancient architecture, and its outstanding skill and technique has high history, historical relic, art and scientific value.The most outstanding feature of Traditional Wood structure is exactly the type of attachment that the framework of post and beam composition adopts Tenon, just find a large amount of wooden construction Tenon connected nodes in Chinese cities before more than 7000 years, between Chinese ancient timber timber compoment subsequently, generally adopt mortise-tenon joint.Tenon just refers to the needs of the connection according to component, and tenon is made in the termination of one of them component, and fourth of the twelve Earthly Branches mouth is made in another component junction, the combination then through these two positions and the node that coupled together by component.Develop into the modern wood structure of today, form of structure constantly changes, and performance is become better and better.In Traditional Wood structure Tenon node, be located in the tenon of mouth inside, the fourth of the twelve Earthly Branches, main is exactly be delivered on post by its band load performance by effect load thereon, therefore higher band load performance guarantee, tenon keeps comparatively tight combination with fourth of the twelve Earthly Branches mouth inwall under external force all the time, and by friction, and mechanical rotation power consumption, finally reach good damping antidetonation object.
Because the traditional living of China is accustomed to, there is the timber frame load bearing constructions such as a large amount of wooden construction, brick timber framed construction and civil structure in vast rural area.Live alone because these buildings are resident, all not through regular seismic design, a large amount of casualtiess and economic asset loss is often caused in earthquake, these building structure are usually because the destruction of node causes in the destruction of earthquake, due to these elemental destruction, add various human factor, and the inherent shortcoming of timber self and deficiency, after tenon and fourth of the twelve Earthly Branches mouth come in contact crimp, tenon width increases and highly reduces, fourth of the twelve Earthly Branches mouth width increases, the connection compactness of tenon and fourth of the twelve Earthly Branches mouth declines, thus reduce the anti-bending strength of mortise-tenon joint node, common failure mode has fourth of the twelve Earthly Branches mouth to expand, tenon is extracted, tenon root fractures, destruction cut off by tenon, and the conquassation of tenon band etc., the reduction of joint behavior, the most direct consequence is exactly the framework reduction of structural stability and increasing of lateral displacement under level cooperation effect, thus strengthen structural damage until collapse.But simultaneously, along with the transformation of China's timber resources the relation between supply and demand, current timber industry aptitude source is transitioned into artificial forest by traditional wildwood, compared with wildwood timber resources, in these timber, juvenile wood proportion is large, and fast growth, cycle of becoming a useful person are short, and its density is lower, mechanical property is poor, especially band load performance is low, and self deficiency of timber exacerbates the deficiency of Tenon joint behavior especially.As the joinery and its construction that wooden construction node is conventional, current Wood in Common Use is on the market adopted to be difficult to the requirement meeting concerned countries standard criterion, more cannot meet the shockproof requirements of highlight lines area building construction simultaneously, therefore the reinforcing of Tenon node be strengthened and just seem by for important.
The reinforcing mode that traditional wooden construction Tenon node is conventional mainly contains following several:
1, the dog described in " a kind of wooden construction antidetonation power consumption dog (patent No. 2013200120080) " is reinforced;
2, " a kind of Tenon node (patent No. 200720032298.X) of the large timber frame of historic building structure of flat steel reinforced ", " a kind of steel and wood composite formula bracing means (patent No. 2014201110165) of historic building fire prevention ", " bracing means (patent No. 200920108275.1) for historic building structure end bay Tenon node ", " bracing means (patent No. 200920108276.6) for internal mortise-tenon joints on wooden-structural ceiling of ancient building ", " bracing means (patent No. 200920108277.0) for tenon-mortise crossing node in middle of wood structure of antique building ", and the flat steel reinforced described in " wood structure node movable bolt hole earthquake-proof reinforced flat iron (patent No. 201020625251.6) ",
3, the curved plate described in " the wooden construction Tenon node (patent No. 201120137388.1) that a kind of curved plate that consumes energy is reinforced " is reinforced;
4, the metal node fastener described in " a kind of reinforcing of wooden construction Tenon node and energy-consumption shock-absorption device (patent No. 201320561955.5) " is reinforced;
5, the carbon fiber wrapped strengthening described in " the Tenon node (patent No. 200720032300.3) of the large timber frame of a kind of carbon cloth reinforced historic building structure ".
Mostly there is following shortcoming in these reinforcing modes:
1. wooden construction Tenon joint reinforcing strengthens the dog in place, band steel, curved plate, metal gusset plate, carbon fiber be all outside exposed, node good looking appearance after reinforcing is low, poor with the outward appearance coordinating and unifying of wood materials, lose the construction aesthetic perception of wooden construction itself;
2., from appearance, adopt steel structure member to strengthen wooden construction node, easily make people produce the sensation of Wood construction safety of structure difference, do not utilize promoting the use of of environmental protection low-carbon wood structural construction;
3. adopt metal connecting piece, need to adopt extra antirust treatment and the working service measure in later stage, technique is loaded down with trivial details.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, propose a kind of board plug type band enhancement mode wooden construction Tenon node, based on the architectural effect of Traditional Wood structure, reinforcing material is buried underground and is hidden in tenon intra-node, do not affecting on the basis of visual appearance, improving the mechanical property of node.
