Non-porous large steel formwork supporting combined fixing structure

HUI YUQING

The invention provides a non-porous large steel formwork supporting combined fixing structure. The non-porous large steel formwork supporting combined fixing structure comprises a dust sticking face steel plate and a horizontal stress rib. The horizontal stress rib is welded on the back surface of the dust-sticking surface steel plate; vertical stress ribs perpendicular to the horizontal stress ribs are further welded to the back face of the dust sticking face steel plate. The vertical stress ribs comprise vertical side ribs and reinforcing vertical ribs 7; the end parts of the reinforcing vertical ribs 7 are welded with the horizontal stress ribs; connecting holes are formed in the vertical stress ribs; the connecting holes are connected through a connecting mechanism and are used for fixing the plurality of vertical stress ribs; the connecting mechanism comprises a set of two connecting plates used for fixing the front faces and the back faces of the vertical stress ribs. Compared with the prior art, the method has the following advantages that a split bolt hole penetrating through a dust sticking surface steel plate and a concrete wall body is omitted, a through-wall bolt does not need to penetrate through during formwork supporting and fixing, dismounting and mounting are convenient and fast, the work efficiency is improved, and a series of problems such as post-treatment of the through-wall bolt hole are solved.

本发明提供了一种无孔大型钢模板支模组合固定结构，包括沾灰面钢板和水平受力肋；所述水平受力肋焊接在所述沾灰面钢板的背面；所述沾灰面钢板的背面还焊接有与所述水平受力肋垂直布置的竖向受力肋；所述竖向受力肋包括竖向边肋和加强立肋7；所述加强立肋7端部与所述水平受力肋焊接；所述竖向受力肋上设有连接孔；所述连接孔通过连接机构连接，用于固定多块所述竖向受力肋；所述连接机构包括一组为两块用于固定所述竖向受力肋正反面的连接板。具有以下优点：本发明取消了穿过粘灰面钢板及砼墙体的对拉螺栓孔，支模固定时，不用穿过穿墙螺栓，拆装方便、快捷，提高工效，减少后期处理穿墙螺栓孔等一系列问题。
