Description
Technical field
The invention belongs to the method in wooden dilapidated buildings renovation field, more particularly to a kind of shockproof reinforcing of log cabin.
Background technology
China is located between the most active two violent earthquakes band in the whole world, and circum-Pacific seismic belt is on the point of in east, and western and southwest is happiness
The refined Mediterranean earthquake zone of horse traction, seismic profile scope is wide, and 6 ~ 9 degree of earthquake territories of China mainland account for the 80% of area, hair shake
Frequency is high.The rural area and rural area of China are then earthquake districts occurred frequently.From live seimic disaster census, strong by equal earthquake
Spend under failure condition, the collapse degree of population injures and deaths, building in the unit administrative division of rural area is far above city, poorer
Poor area, it is disaster-stricken more serious.Its main cause is backward in economy, and a large amount of houses owed by a citizen are in mostly wooden tile-roofed house, and house is old to be lacked
Caused by weary earthquake resistant construction, shock resistance difference.Existing common wooden frame structure has following several types：
(1) pin wooden frame (flat roof type).General to make the weak post of brutal or crossbeam buttress shaft, beam-to-column joint is simple, lumber quality compared with
Difference, roof is typically made with mud or lime Jiao's quarrel thick 10 ~ 30cm, therefore roofing weight is larger;House is short and small, roof pitch
It is smaller, it is to avoid tall and big and unstable pediment.
(2) pin wooden frame (slope top formula).This type house, which is divided into, has corridor tall building and without two kinds of corridor tall building, there is the house in corridor tall building
General to have 3 ~ 4 pillars, the house without corridor tall building only has front and rear two pillars, and using various more than the roofing in two kinds of houses
Tile roofing, weight is than larger.
(3) pin wood roof truss.House is taller and bigger, spaciousness, roof truss and pin with wearing feather joint, some node plus dog or
Iron nail is combined.
(4) bucket gallows timber is worn.Vertically and horizontally wooden frame and pin coak combine to form space frame, and crossbeam end is used
Dowel typically has 3 ~ 5 posts through can prevent out of joint per Pin roof trusses, therefore, wear bucket timber framed house connecting structure and
Globality is all stronger, and lateral stability is also preferable, and framework is seen in longitudinally connected good being formed.Mostly one, two-layer structure,
Three layers can also be accomplished.The common premises such as private residence, teaching and office have use.In shape, it is divided to a Po Shui, two Po Shui and four
Slope water form, conventional is two slope boiled water room rooms of the landing of three posts or the landing of five posts.
In the last few years rural area using log cabin all the more common for wearing bucket timber-frame structure because wearing bucket gallows timber bearing system
Separated with building enclosure.Similar modern frame structure, load-bearing is mainly undertaken by wooden frame, and wall is used as building enclosure.Planar cloth
Office is versatile and flexible, can meet different use requirements.There is preferable anti-seismic performance.The node joggle of bucket timber structure is worn, is such as detained
Tenon, double dovetail key, joggle can be with the globalities of enhancing structure, to reduce earthquake;The energy that bean column node absorbs is more；Structure is light, ground
Shake load small；Elasticity is good, and restoring force is big after deformation；Cycle is long, it is not easy to and solid soil resonates.There is wall frame
The feature do not collapsed.Gather materials on the spot and well adapt to various regions weather conditions.Load-bearing structure timber, building enclosure loam wall, soil
Base wall, pebble wall, wood siding wall, bamboo sheathing wall etc., these construction materials are all easier to take in locality.Construction technology letter
It is single.
Although wearing bucket timber structure has preferable anti-seismic performance, in ago earthquake centre, some weaknesses of bucket timber structure are worn
Link still is revealed out.Wear bucket timber structure and destruction occur in ago earthquake centre, these destructions
Mainly there is the following aspects：
(1) pin fractures.The wooden component of bucket is worn in manufacturing process, larger to the section weakening ratio of pillar, tenon mouthful compares comparatively dense.
Wooden frame deformation ratio is larger in earthquake, pin is fractureed at the weakening of section.Such destruction is mainly manifested in floor layer absolute altitude and indulged
At laterally.In addition with because joggle at pin spreading is insecure and fractures.The selection of indivedual pins is improper, is there is larger carrying
On the section of power, exostosis is occurred in that, weak part is formed, pin also easily fractures here in earthquake.
(2) wooden frame destruction caused by the connection of the component such as beam, post, purlin is insecure.Always vertically and horizontally wooden frame and pin connection are used
Be tenon (be generally dovetail).Because the hardness of timber is little, tenon node can loosen after wood shrinkage, if vibrations are compared in earthquake
Greatly, then can occur phenomenon out of joint.Floor layer joist and the dovetail of crossbeam junction are too short, and tenon mouthful is pulled during earthquake, so as to lead
Cause superstructure slump.
(3) roof truss is tilted or collapsed.The reason for roof truss is destroyed is relatively more, wherein most importantly wearing bucket timber framed house
Lateral rigidity is smaller, and particularly longitudinal rigidity is smaller, is swung in earthquake, inclined building after earthquake.Horizontal whole Pin
Gallows timber is not worn a tree, used in making timber for boats and run through, and makes each post and crosshead displacement excessive, causes inclined building or collapses.
(4) suspension column is moved with base for post.When pillar is not connected with base for post (base block) with tenon, pin is directly put
On base for post (base block), occurs the translation changing of the relative positions because horizontal jitter causes between post and base for post during earthquake.Appearance post also
Root is tilted, and pillar hangs empty or fallen.
(5) house height, the slope of roof are more heavier than larger, roof weight, and top heavy causes the destruction in house；Wooden structure
Part is rotten, and some houses are long neglected and in disrepair, and wooden component is rotten to be degraded, and section weakens, and is destroyed first during earthquake and then causes other structures
The destruction of part.
