Stable building expansion joint structure

Abstract

The invention relates to a stable building expansion joint structure which comprises a floor slab, and an expansion joint is arranged on the floor slab. The outer side of the first metal plate extends to the right side of the expansion joint; the outer side of the second metal plate is folded downwards and abuts against a floor slab on the right side of the expansion joint; a supporting plate is arranged at the bottom of the turnover part of the second metal plate in an upward inclined mode, the supporting reinforcing mechanism comprises a first supporting convex edge fixedly connected to the supporting plate, and a corresponding first supporting shaft is rotatably embedded in the top of the first supporting convex edge; the top end of the first supporting shaft abuts against the lower side face of the first metal plate. The cement mortar layer covers the upper side surfaces of the floor slab, the first metal plate and the second metal plate; and the panel layer is fixedly arranged on the upper side of the cement mortar layer. On the basis that the structural stability is ensured, main components of the structure can be effectively assembled in a hidden mode.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a stable building expansion joint structure. Background technique [0002] Construction expansion joints are expansion joints, which refer to a structural joint set at an appropriate part along the construction joint direction of a building or structure in order to prevent cracks or damage to the structure due to climate temperature changes (thermal expansion, cold contraction). [0003] Among the existing stable building expansion joint structures, there are typically two kinds of covered expansion joints or double-slit expansion joints. The main components used are the cover plates of the covered expansion joint structure or double-slit The base of the expansion joint structure cannot be installed in a concealed manner. With the improvement of people's requirements for architectural decoration, this is undoubtedly unacceptable. [0004] Therefore, on the basis of...
