A reinforcing device of concrete wall steel meshes comprises an H steel, a plurality of reinforcing ribs mounted on the H steel and connecting plates mounted at two ends of the H steel. Flange plates of the H steel are symmetrically provided with a plurality of screw connecting holes used for connecting screws, and the screws are arranged in the screw connecting holes symmetrically. The connecting plats are provided with connecting plate screw holes used for connecting to connecting plates of another H steel. The reinforcing device is simple in structure and convenient to use, deformation of the concrete wall steel meshes is reduced, and the problem of mesh shifting, deforming or even collapsing since meshes are fixed by wind cables are solved; in addition, working efficiency and construction quality are improved, construction process is faster, and safety of high-altitude operations is guaranteed.

The invention provides a corrugated plate-shaft type pull rod connecting structure for prefabricated part connection. The corrugated plate-shaft type pull rod connecting structure comprises prefabricated parts, corrugated plates, shaft pull rods, universal hinges, pre-buried straight steel plates and bolts. The top plate and the bottom plate of the prefabricated part are connected with the corrugated plate through the pre-buried straight steel plates and the bolts respectively. And the shaft pull rod is connected with the universal hinge. Bolts penetrate through the hole channels so that the shaft pull rods can be connected with the top and bottom plates of the prefabricated parts and the pre-buried straight steel plates. Through corrugated compression and expansion of the corrugated plates, extension of the shaft pull rods and rotation of the universal hinges, vertical, transverse and rotary displacement differences between the adjacent prefabricated parts are achieved, overlarge local ...
