Description

Assembled horizontal tie rod assembly in concrete wall formwork

technical field

The invention relates to the technical field of cast-in-place concrete construction of buildings, in particular to a self-assembled horizontal tie rod assembly in a support formwork of a concrete wall.

Background technique

In the cast-in-place concrete structure, the side formwork of the vertical members (such as walls, columns, deep beams, etc.) bears a large horizontal thrust of the unconsolidated concrete. In order to solve the problem of formwork, it is more effective to use a steel horizontal rod to bear the horizontal force. At present, there are many construction methods for horizontal rods, but they always pay attention to one and the other, and cannot be solved well. It seems that as long as the horizontal rod can be combined with the side mold, the force transmission is reliable, and the disassembly and assembly operations are convenient, but this is not the case. The best idea is: it can locate the two rows of steel bars in the vertical member in the mold, so that the vertical side position of the row of steel bars and the distance in the template meet the requirements of the specification, and can meet the requirements of the double-row steel bar structure of the wall. It can also be combined with the formwork, and it is easy to assemble and disassemble, and the location is flexible; it must also be able to meet the horizontal tie force requirements in the formwork, so that the force transmission is reliable; for walls with waterproof requirements, It is also necessary to meet the water-stop requirements for the wall after pouring.
