摘要
为了解决H型钢梁+叠合板组合楼盖在施工过程中的楼板支撑问题,提出了一种免架体支撑的、端部可调的叠合楼板支撑结构.该支撑结构由端部可调支座和对拼冷弯薄壁C型钢两部分组成.建立13个免架体叠合楼板支撑结构的有限元模型,研究其在施工荷载作用下的受弯承载性能.分别研究C型钢板件厚度、腹板高度和翼缘宽度对支撑结构抗弯承载能力的影响,给出支撑结构的使用意见,结果表明使用意见可以较好地满足施工要求.
Abstract
In order to solve H-type steel beam+laminated slab composite floor's support issues during construction,a new type of floor support structure with no scaffolding support with an adjustable end is proposed.The support structure consists of two parts:adjustable support at the end and thin-walled C-shaped steel.A finite element model of 13 floor support structures with no scaffolding support was established to study their flexural bearing capacity under construction loads.The effects of C-shaped steel plate thickness,web height and flange width on the flexural load bearing capacity of the support structure were studied in models.The results show that the use of the support structure can meet the construction requirements.
