交通部建厂工程局思濛工地的广大职工,响应毛主席“工业学大庆”的伟大号召,充分发挥工人、干部和技术人员的积极性,在吸取兄弟单位先进经验基础上,在工业厂房设计中采用了天井式天窗、管式拼装屋架和翻转脱模电热张拉等新技术。在试验和生产实践的基础上,已完成了一套6米柱距、非采暖地区的单层厂房天井式天窗屋盖系统图集,并在五个车间中采用(图1)。这种 The staff of the Construction Engineering Bureau of the Ministry of Transport at Simon Mould Site responded to Chairman Mao’s “Great Daqing” call and gave full play to the enthusiasm of the workers, cadres and technicians. Based on the advanced experience of the fraternal unit, the design of the industrial plant was completed. New technologies such as patio-style skylights, tube-type trussed roof trusses, and roll-away demoulding and electric stretching are used. On the basis of experiments and production practices, a set of atrium skylight roof systems for a 6-meter column spacing and non-heating area has been completed and used in five workshops (Figure 1).
