1.屋顶空心板改为柔性接头,在支撑空心板处铺一层油毡,缝内填以可塑性材料,使每块空心板两端可自由伸缩,这样气温升高时,屋盖产生的温度应力大大减小。为保证房屋抗震能力,用屋顶圈梁将空心板箍住,并沿房屋长向在板缝内加筋,既能使空心板自由伸缩,又能保证房屋的整体性。 2.建议推广双层屋面。五层住宅楼如改为双层屋面,每平方建筑面积仅增加投资2元左右,也可作反辐射层(涂刷铝基反光材料)。
1. The roof hollow slab is replaced with a flexible joint, a layer of linoleum is placed on the supporting hollow slab, and the plastic material is filled in the seam so that the ends of each hollow slab can be freely retracted, so that the temperature stress generated by the roof when the temperature rises. Greatly reduced. In order to ensure the earthquake resistance of the house, the hollow slab is hooped with a roof ring beam and reinforced in the slab seam along the length of the house. This not only enables the hollow slab to flex freely, but also ensures the integrity of the house. 2. It is recommended to promote double roofing. If a five-storey residential building is changed to a double-storey roof, it will only increase investment by about 2 yuan per square meter of building area, and it may also be used as a counter-radiation layer (painted aluminum-based reflective material).
