Form board supporting keel connection reinforcement device for concrete pouring and dismantling-free heat preservation form board

Abstract

The invention discloses a form board supporting keel connection reinforcement device for concrete pouring and a dismantling-free heat preservation form board. A keel body, a T-shaped lock rod and a clamping seat are included; the lower end of the T-shaped lock rod is provided with a rectangular clamping head, one end of the clamping seat is provided with steel tie bars extending into concrete, theother end of the clamping seat abuts against the keel body, and a clamping cavity capable of containing the clamping head at the lower end of the T-shaped lock rod is arranged in the clamping seat; astrip-shaped groove is formed in the side, close to the keel body, of the clamping seat, and an inserting slot for the T-shaped lock rod to penetrate is formed in the keel body; at least the part, extending outside the keel body, of the T-shaped lock rod is a threaded section, and a threaded section is sleeved with a locking nut; and the keel body is locked by the locking nut to make fixing between the keel body and the dismantling-free heat preservation form board easier, and disassembly is easier. The supporting keel connection reinforcement device securely fixes the dismantling-free heat preservation form board in a concrete wall through the retaining clamping seat and the steel tie bars, the structure is simple, and the usability is strong.

Description

technical field [0001] The invention relates to a formwork support keel connection and reinforcement device for concrete pouring and a dismantling-free thermal insulation formwork, belonging to the field of construction. Background technique [0002] At present, most of the thermal insulation methods used for the outer wall of reinforced concrete buildings are to support the formwork first and then pour the concrete. After the setting period is reached, the formwork is removed, and then the thermal insulation system is laid on the surface of the formed reinforced concrete outer wall by pasting and post-installing anchors. This method The construction process is complicated and the construction quality of the subsequent insulation system is difficult to guarantee. Therefore, an external wall thermal insulation structure and construction method that uses a dismantling-free thermal insulation formwork on the outside while pouring the reinforced concrete external wall came into ...

AI Technical Summary

Problems solved by technology

This mode of thermal insulation formwork supports connection and fixation has complex procedures and low work efficiency, and it is difficult to control the flatness and width of the plate seams, and there is a hidden danger of water seepage in the holes where the formwork passes through the steel bars.
