Direct throw too wasteful and materials have been used though, but it's still relatively long life for the old material, then we can continue to use, we can take down the sheet made of shelves, benches, chairs and so on. Appears 2, brick and concrete tenements apartment renovation unreasonable, so small and so on, so many people will hit the wall of old, began a series of land and other reconstruction knock, before the old house, the wall bearing play seismic effects, followed by maintaining separate role will be weakened wall will change the beam load and seismic capacity of the wall will be carried out there is a big security risk. 3, the renovation project specialized for such a dangerous and difficult renovation project, we'd better find a more professional company to change the wall to change the beam girder. Liang Xin Li Nanyang wall change is good choice for you. Brick beams, walls change the beam, the beam of the load-bearing walls to change other provisions beam section 1, brick beams, walls change the beam, the beam span load-bearing walls change (crosswise beam short span) for the calculation of the beam; generally cloth advantageous when calculating beam deflection, to consider the beam compression zone Slab (flange); and when the load is greater than or equal 40KN / M greater line load, the height of the beam can take the maximum (the same applies to the cantilever beam) action may be appropriate bagging (1/1000 ~ ~ ~ ~ 3/1000); general main beam greater than or equal to the secondary beam +50 (double ribs take +100); 2, brick beams, walls change Liang load-bearing walls to change the beam for office buildings, shopping malls 8 meters across the beam when the beam takes 300 * 800 poor wall Henan team to change beams, should take 300 * 700, how much money changed Henan wall beams, for some large-span public buildings the width of the beam should be appropriately modified to increase the Henan wall beam method, should take 300 or more, preferably 350,400 to take, because the beam width widening, favorable shear, in line with the principle of "strong shear weak bending" of. 350 wide beam, with four limbs hoop can reduce the diameter of the stirrup, the main beam broadening Henan wall beams change, in favor of the secondary beam of steel anchor.

Door frames can not touch; door frames of these doors are embedded in concrete, if Chaigai, will destroy the building structure, reducing the safety factor. And it destroyed the front of the building structure, re-install the new door is even more difficult. 6. Bathroom and kitchen floor waterproof layer can not touch; on the ground in these places have a waterproof layer, if destroyed, downstairs will become "Water Curtain Cave." Therefore, when you replace the flooring, it must have noticed to damage the waterproof layer.
