A detailed calculation results verified the moment and deflection of lapped connection beam is similar as that of continuous beam. So the continuous beam analytic model is suitable for analyzing roof purlins. However, how to guarantee the stability of the bearing compressed zone without the tension bar in bottom flange greatly affect the use of continuous purlins in project, theoretical analysis is carried out.

对搭接模型和均匀连续梁模型的计算结果进行对比，证明采用均匀连续梁的分析模型可较为准确地描述连续搭接檩条的内力状况；而对于仅在檩条上翼缘附近设置拉条，竖向力作用下如何保证支座区受压下翼缘的稳定性在很大程度上影响着连续檩条在工程中的推广应用，因此对其进行了理论分析。

On both sides of the head, bo palletizer gables and jump out after all, coping with brick and WaiHu bolts into the curve, delicate and elegant, In front of the hall YanXia is WangZhuan grinding and Chuan bent with very precise porch corridor, look up, its monumental made by artificial and materials that, And the bridge of short column and column, is not a simple shu to use a few short wood, but installation high-relief curving flowers.the curving flowers and leaves, Lu carved into a cloud, LiangYun fog, not only can satisfy the structural component of the requirements, and the proper decoration, try and do not provide craftsmanship.

两侧山墙的垛头、博缝及后檐出跳，也都用砖磨成道道内、外弧的曲线，精致而又素雅；厅屋前檐下是把望砖磨成与弯椽配合得极为精确的轩廊，抬头望去令人赞叹不已，其制作所耗费的人工和材料可想而知；还有那梁架上的短柱与蜀柱部位，不是简单地用几根短木，而是安装高浮雕和透雕雕刻成荷叶墩、栌斗、山雾云、抱梁云构件，不仅能满足结构上的要求，又恰到好处的进行了装饰，真可谓两全齐美，别具匠心。
