Supporting device and fixing structure for road deformation joint concrete formwork

HU JIANKANG / TAO LIYE

The invention relates to a supporting device and a fixing structure for a road deformation joint concrete formwork. The supporting device comprises a supporting working part, and further comprises a handheld rotating part connected with the supporting working part so as to change the supporting working angle of the supporting working part, the supporting working part is H-shaped and comprises twoparallel and opposite light round bars, and the middle parts of the two light round bars are connected through a torque transmission connecting rib; the handheld rotating part is in a T shape and comprises an extension rod and a rotating handle rod transversely arranged at one end of the extension rod, the other end of the extension rod is connected to the middle of the torque transmission connecting rib, and the extension rod is parallel to the two polished round bars. The supporting device is simple in structure, effective in supporting, convenient to use and disassemble, capable of effectively improving construction efficiency, capable of being recycled after being disassembled and capable of saving cost; and when the supporting device is used, the supporting working part extends into the position between two end formworks in the mode of being parallel to the two spaced end formworks, and then effective supporting and fixing can be achieved by rotating the handle rod by 90 DEG.

本发明涉及一种道路变形缝混凝土模板支持装置及固定结构，支持装置包括支撑工作部；还包括与所述支撑工作部相连的手持转动部以便改变支撑工作部的支撑工作角度，所述支撑工作部呈H形，包括两平行正对的光圆棒料，两光圆棒料的中部之间通过传扭连接筋相连；所述手持转动部呈T形，包括延伸杆和横置于延伸杆一端的转动手柄杆，延伸杆的另一端连接于传扭连接筋的中部，延伸杆平行于两光圆棒料。本发明的支撑装置结构简单，支撑有效，使用和拆卸都很方便，可有效提高施工效率，拆卸之后也可以再次循环利用，节约成本，使用时，将支撑工作部以平行于两间隔的端模板的形式伸入到两端模板之间，再通过转动手柄杆转动90°即可实现有效支撑固定。
