Overhanging floor below the floor leakage does not

will not leak, overhanging floor where the floor leakage risk is greater, overhanging layer is the roof or top floor outward hanging out of the lower part of the wall. Overhanging layer is easy to leak because the general channel steel are the last to remove, when the external walls have been done, after the removal will leave a number of large square mouth, although the later will make up for these holes, but due to the demolition of the peripheral scaffolding these means that it has come to the end of the time to do things are more scribbling, casually patched up, which in the later stages of water seepage is prone to occur.

The advantages and disadvantages of buying a suspended layer

Buy a suspended layer although the home will be part of the space, but whether it is the traditional I-beam suspension or the new beam side of the pre-embedded suspension, there will be a leakage of water seepage in the later stages of the hidden danger. I-beam overhangs generally need to go through the wall, even if the later repair, but still easy to leak, while the beam side of the pre-embedded overhangs because of the existence of screw holes, the external wall is also easy to leak. No wonder my friend said I'd be guilty if I moved in later.

Want to judge the overhanging layer is actually very simple, overhanging basically not more than 20 meters at a time and in 20 meters or so, and our housing is generally 3 meters a layer, that is to say, every 6 layers of an overhang, the first overhang is in the 6 layer, the second overhang is from the 7th floor to start, so no matter whether it's the 6th floor or the 7th floor, leakage will be more likely to my home, 13 floors belong to the overhanging layer. Some neighborhoods have stores on the 1st floor and separate housing on the 2nd floor, so the overhangs may also be built from the 3rd floor.

Which floor of an overhanging floor will leak

The upper floors of an overhanging floor will leak. Suspended scaffolding generally has two kinds: one is a pick for each layer, the bottom of the uprights on top of the floor, beams or walls and other parts of the building, tilted outward and fixed, in its upper part of the crossbar, paving scaffolding boards to form the construction layer, the construction of a layer of height, to be transferred to the upper layer, and then re-erected scaffolding, to provide the upper layer of the construction; the other kind of multi-layer pick, the full height of the scaffolding is divided into a number of segments, each segment of the erection of a height of not more than 20m, the use of cantilevered beams or cantilevered frame for scaffolding foundation segment cantilevered segment scaffolding, using this method can be set up more than 50m scaffolding, cantilevered scaffolding facade shall be full of scissor braces.

If the project is very urgent outdoor backfill or zero meters below the structural acceptance, then the height of the floor scaffolding for the height of the basement and the height of the first floor and the height of a layer, from the top of the first floor that is the structure of the second floor surface began to build cantilevered shelves, racks of 18m high (which has been taken into account the height of the daughter wall and the height of the body guard railing), the advantage of this is that the floor frame after the dismantling and acceptance of the basement wall waterproofing and acceptance of steps such as waterproofing directly. And outdoor backfill steps, but the disadvantages are equally obvious, a large number of overhanging beams (generally 16 # I-beam or channel steel) a one-time investment, as well as steel wire rope, U-type pulling a one-time investment, and the rest of the increase in labor costs and a certain delay in the construction period. If you are not in a hurry to backfill, it is recommended to build a one-time to the top, the total height of 30m, single-pole double-row scaffolding can be achieved, fast schedule, saving labor, but the disadvantage is that the amount of steel pipe fasteners is too large, the use of a long cycle.
