Speak of a dangerous house, people associates very easily " project of bean curd broken bits " , this is to use a the most frequent word in recent years. To the building, no matter " bean curd broken bits " appear in which place, can make safe hidden trouble to the building, be serious degree differs only.
In the country " building management provides urban hazard " in, the definition of dangerous building is to point to, "The structure damages badly already or bearing component part already belonged to critical component part, lose structural stability and carrying capacity likely at any time, unwarrantable the building that live and uses security. Unwarrantable the building that live and uses security..
Press the integral structure of the building, the building can be divided bearing for foundation foundation, upside structure and palisade structure 3 component. Say objectively, besides the reason of project quality, sometimes a few changes that environmental element causes explicit condition, also can bring about a building to suffer the destruction of different level.
Building of one point danger
One, the technical standard of appraisal danger building is as follows:
1, foundation foundation and upside bearing structure. Advocate if detect,foundation foundation has without sedimentation, displacement, craze is out of shape wait for evidence, if foundation foundation happens inhomogenous sedimentation be out of shape, right girth and upside structure can cause an effect, the most apparent phenomenon is craze, be close to when bend slope 1% when should cause high vigilance, if break already was close to 10mm, perhaps sedimentation when already causing a building to tilt, bearing to upside the structure basically is the examination bearings column, main wall, bearing the carrying capacity of bridge, construction and join, be out of shape with craze.
2, structure of system of build by laying bricks or stones. Structure of system of build by laying bricks or stones should check freely wall to join place and place of wall body corner have mainly mix without craze be out of shape. If press press wall, column produces an edge to get the break of force direction (perpendicular to break) , and seam bounty at 2mm, seam grow the vertical stroke that exceeds a tall 1/3 to high vigilance is needed when break, if be break of shape of a few moire only (shrinkage crack) or plasterer break is not big question, the component part of body of build by laying bricks or stones of prejudicial press press still should notice whether the examination has horizontal break.
3, ferroconcrete component. Its check a key is pedestal place, suffer pull area and suffer cut an area to whether have craze appearance, and distributing interstitially, trend, width and length. Frame structure should notice to check Bian Zhu, corner post and crucial node place. The building of foundation frame structure and multilayer the building should be checked mainly turn a fission form circumstance of the layer. Ferroconcrete bridge stands in the mid discovery of bridge to break, on one of side direction outspread the 2/3 above that amounts to Liang Gao, seam wide be more than 0.5mm or appear around pedestal cut inclined break, seam bounty at 0.4mm, these break are dangerous break, must take seriously highly. The craze that still must notice to check building shell and room lid additionally and be out of shape circumstance.
Other and tectonic building must notice the item of the examination has:
1, whether does the woodiness that timberwork building wants to check wooden member have the sign such as eat by moth of wet corrupt, bug. The structure that wear tenon should check mortise to whether rupture mainly, whether did tenon division head already become loose lose action.
2, in earthy structure building, body of the foundation that needs wall of key perambulate adobe and earthy wall, wall is damp, foundation has without mousehole, whether does wall body have tilt. Earthy wall has crackle to have nothing to do with, those who be afraid of is to be mixed damply tilt.
Roof tuss part should check staff of collate fluctuation string mainly curve degree and level or the perpendicular system that prop up is effective, also should notice perambulate roof tuss has at the same time tilt without plane phenomenon.
2, the assess method of building risk level
1, it is integrated assess above all, it divides an administrative levels to undertake:
Ground floor second for appraisal of sex of component part danger, part of one's job of its grade assess is critical component part (Td) with blame danger component (Fd) two kinds.
The 2nd administrative levels is building component (foundation foundation, upside bearings structure, palisade structure) dangerous sex appraisal, cent of its grade assess is grade of A, B, C, d4.
The third administrative levels is appraisal of sex of integral building danger, part of one's job of its grade assess is grade of A, B, C, D4.
2, the rate of building danger sex:
Class A: The structure bears the weight of force can satisfy normal use requirement, did not discover critical point, building construction is safe.
B class: The structure bears the weight of power can satisfy normal use requirement basically, individual construction component part is in quicksand, but do not affect main body structure, satisfy normal use requirement basically.
C class: The part bearings the structure bears the weight of force cannot satisfy normal use requirement, local occurrence danger affection, make local dangerous house.
D class: Bearing the structure bears the weight of force already cannot satisfy normal use requirement, affection of building whole occurrence danger, make whole dangerous house.
It is very important to put an end to danger building to lay good foundation
3, the average order of perambulate dangerous house
The dangerous house is with be appraisal unit, undertake according to floor area metric, cent foundation foundation, upside bearings structure, palisade structure undertakes perambulate 3 times partly. The program of survey and measure are by fall and go up, by outside reach inside, chase a layer to undertake. Want the surroundings with perambulate located building and drainage system above all, the 4 large part that are perambulate building next, frontispiece, outside wall and exterior configuration, it is corridor, stair well is mixed then indoor, final perambulate house covers a part.
If ◆ feels this literary works is good, remember nodding assist, comment and transmit; To small make up add leg of drumstick, duck, goose leg.
