So to common the person that buy a house, be afraid of the house that buys quality to close nevertheless, so how to detect building quality problem?
One, set out from the foundation, see a basis
Generally speaking, the fundamental form of the building is different, for example high-level residence is about to use picket foundation, box form base, and the villa of low layer and multilayer apartment use a form base commonly, the foundation bore building upside all load, for example self-prossessed, furniture, person is waited a moment, send all active force reliably in foundation, be out of shape when building metope craze, floor, the quality problem such as roofing ooze water is a foundation likely is inhomogenous sedimentation, destroyed building construction and cause.
2, look for break
The person that buy a house discovers wall body occurrence break when test house, this building may be certain link occurrence problem, wall body craze basically has 3 kinds of state:
1, the building is inhomogenous sedimentation the break that cause: Expression is tilt, of tropism of in the right way, well-regulated break. Causing this kind of interstitial main reason is to build the foundation when the house and foundation to was not hit good, the safety to the building and use influential.
2, the break that causes by temperature: Can divide again for two kinds of circumstances, one kind is plaster break only, not experience wall body, this kind of break is mixed to the safety of the building use do not have an influence; Another kind is the R-joining on windowsill, doorcase, may ooze water, the influence is used.
3, the break that the wall body below bridge gets force to cause greatly too: The safety to the building and use influential. The account that produces this kind of break basically has 2, it is the issue gave when the building is designed, pressure of wall body susceptive is too great; The quality that is wall body is bad, bear control capacity too poor.
3, examination building floor
Building floor basically includes two implications: One is the floor of rock-bottom ground and floor. Deciding above all to floor is prefab board still be cast-in-place board. The floor of low layer and tier building basically is prefabricated components, main observation floor has without break, can divide it is two kinds as follows: Get the break that force produces, advocate if foundation is inhomogenous,sedimentation, concrete strength and concrete board thick serious inadequacy, calamity and accident generation; Be not the break of generation getting power: Advocate if be mixed by temperature, systole,expand reach the element such as construction to arise. What because building intensity is mixed,thick serious inadequacy, calamity and accident produce building board is interstitial, bigger to structural influence.
4, see roofing
The housetop great majority of civil residence is flat roof and slope housetop. The function with the mainest roof is waterproof, heat preservation and heat insolation. To carrying the resident of the layer on the head, roofing is a very main quality index. The leakage of roofing appears in the place that the structure changes more, for instance the joint of roof boarding and wall body, adjustable seam, sedimentation seam place to wait.
Not be must when the house has been built go again error correction, be inferior to still be in in building body when building, do monitoring of whole technological process ahead of schedule, begin monitoring to develop business construction in construction period square, set out from detail, watch each part carefully.
