JIA RANXU / WU YABO / CHEN ZHONG / YE WENQI / SHAO ZHIBING

The invention belongs to the technical field of industrial factory building construction, and discloses a high-altitude overweight frame beam two-way bailey formwork steel platform and a construction method. The platform comprises a two-way bailey formwork steel platform body, the two-way bailey formwork steel platform body comprises concrete frame columns, a transverse frame beam bailey steel platform is arranged between the left and right adjacent concrete frame columns, and a longitudinal frame beam bailey steel platform is arranged between the front and back opposite concrete frame columns. Bailey truss main beams are arranged on the two sides of the longitudinal frame beam Bailey steel platform and the two sides of the transverse frame beam Bailey steel platform. Bailey steel platforms are adopted in the longitudinal and transverse supporting modes, and compared with an original combined type high and large formwork supporting steel platform, assembling is more convenient and faster; a beret steel platform formwork supporting platform is adjusted from a lower chord member to an upper chord member, the space used for formwork supporting of a frame beam is deducted, the operation space on each side is expanded to 1000 mm from original 500 mm, and the space of the whole operation platform is doubled.

本发明属于工业厂房施工技术领域，公开了一种高空超重框架梁双向贝雷支模钢平台及施工方法。该平台包括双向贝雷支模钢平台本体，双向贝雷支模钢平台本体包括混凝土框架柱，左右相邻的两个混凝土框架柱之间设置有一个横向框架梁贝雷钢平台，前后相对的两个混凝土框架柱之间设置有一个纵向框架梁贝雷钢平台，纵向框架梁贝雷钢平台与横向框架梁贝雷钢平台的两侧均设置有贝雷架主梁。本发明纵横向支撑方式均采用贝雷钢平台，对比原有的组合式高大支模钢平台，其拼装更为方便快捷；贝雷钢平台支模平台由下弦杆调整为上弦杆，扣除掉框架梁的支模所用空间，每侧操作空间由原来的500mm扩大至1000mm，整个操作平台空间扩大一倍。
