1、濟(jì)南防水http://www.liveevil.cn/介紹改變預(yù)留施工縫的支座支承情況,改為簡(jiǎn)支支座,斷開負(fù)筋,調(diào)整此處板底筋(配筋量增大)和負(fù)筋(配筋量減小)。這樣,改變了樓板受力狀態(tài),應(yīng)重新設(shè)計(jì)計(jì)算,并征得設(shè)計(jì)單位同意。
Jinan waterproof construction joints introduce change to reserve a seat support cases, instead of simply supported seat, disconnect negative reinforcement, reinforcement bottom plate adjustment here (reinforcement volume increases) and
negative reinforcement (reinforcement volume decreases). Thus, changing the floor by the force of the state, should be re-design calculations, design units and obtain consent.
2、濟(jì)南防水談到降低標(biāo)高,此調(diào)整影響結(jié)構(gòu)抗震性能很小,因?yàn)闃欠克椒较蚩咳α豪Y(jié),豎向靠構(gòu)造柱拉結(jié)。
Jinan waterproof Speaking lower elevation, this adjustment affects small seismic performance, because the building horizontally by Rachel ring beam, vertical structural columns by Rachel.
3、濟(jì)南防水建議施工縫處澆筑混凝土?xí)r,可先澆筑圈梁混凝土,后澆筑現(xiàn)澆板混凝土,直接在截面處設(shè)置現(xiàn)澆板的垂直側(cè)模,將混凝土振搗密實(shí)。
Jinan waterproof construction joints recommend pouring concrete ring beam can be pouring concrete, after pouring concrete Slab, Slab set directly in the cross section perpendicular to the side of the mold, the vibration compacting
concrete.
4、濟(jì)南防水http://www.liveevil.cn/提醒大面積樓層結(jié)構(gòu)設(shè)計(jì)時(shí),應(yīng)該沿縱向每隔20米左右設(shè)置一條施工縫,這樣做既能保證原設(shè)計(jì)力學(xué)假定,又能消除現(xiàn)澆板收縮裂縫,同時(shí)也能解決由于屋面現(xiàn)澆板熱脹引起的頂層窗洞口處出現(xiàn)八字縫。
Jinan waterproof remind large floor design, it should set about 20 meters along the longitudinal construction joints every one, so do not only ensure that the original design of the mechanical assumption, but also to eliminate Slab shrinkage cracks, but also to solve because of the roof Cast the hole at the top of the window plate thermal expansion joints caused by the emergence of character.
