Demolition of rural cottage bearing wall, take reinforced beam OK?
If you want to tear down the load wall length of about 5 meters, you may need a high 400 of the I-beam (small may collapse, waist too big, can not be used), you can not get up. With the crane can, but regardless of soil hanging or foreign crane, probably have to open the house cover, it is estimated that not yet started, you head first big.
Non seismic 6 degrees and above area can use the I-steel beam generation bearing wall bearing, but must be in the wall before the good security measures in the premise, installed and fixed I-beam, and wall.
In the seismic fortification of 6 degrees or more areas should not be removed, otherwise it will increase the spacing between the walls, to weaken the integrity of the building, adverse earthquake, once the earthquake occurred, will reduce the escape time.
It's more feasible to make reinforced concrete beams. When the bottom formwork, the tie bar, the vertical measuring die, the pouring funnel of the inclined funnel and the concrete are poured, when the concrete strength reaches a certain strength, the funnel concrete is timely removed, the design age is disassembled, the bottom mold is taken, the safety measures are carried out, and the bearing wall is disassembled, and the work is done.To remind you whether or steel reinforced concrete beam, to ask a professional architectural design consulting and design personnel to the scene, not to engage in their own, you live than the new building is complex, cumbersome, safety risk, be careful! Earnestly!
