预制方案对装配式剪力墙工程造价的影响分析

Analysis of the Influence of Prefabrication Scheme on the Cost of Prefabricated Shear Wall

文中对装配式剪力墙与传统剪力墙经济性进行对比分析,并开展预制率对装配式剪力墙结构经济效益的影响研究。结果表明,装配式建筑的人工费及设备费总造价均比传统现浇结构总造价低,其分部工程费和材料费用远远高于传统现浇结构体系的总造价,增幅分别达到39%、51%。装配式建筑分部工程中的钢筋混凝土及预制混凝土均比传统现浇结构总造价高,其现浇构件及砌筑工程费用均低于传统现浇结构体系的总造价。每提升1%的预制率,分部工程费用及材料费分别增加260万元、335万元;每提升1%的预制率,人工费用及设备费分别降低21万元、2.9万元。

In this paper,the economy of prefabricated shear wall and traditional shear wall is compared and analyzed,and the influence of prefabricated shear wall rate on the economic benefit of prefabricated shear wall structure is studied.The results show that the total cost of labor and equipment is lower than the total cost of traditional cast-in-place structure,and the cost of engineering and material is much higher than the total cost of traditional cast-in-place structure system,with an increase of 39%and 51%respectively.The total cost of reinforced concrete and precast concrete is higher than that of traditional cast-in-place structure,and the cost of cast-in-place components and masonry is lower than that of traditional cast-in-place structure system.For each 1%increase in prefabrication rate,the division engineering cost and material cost increased by 2.6 million yuan and 3.35 million yuan respectively.For every 1%increase in prefabrication rate,labor costs and equipment costs are reduced by 210,000 yuan and 29,000 yuan respectively.
