Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a steel bar truss floor deck parapet construction structure. Background Art

[0002] As the protective structure surrounding a building's roof, a parapet wall primarily protects personnel and serves as a decorative element for the building's facade. Many building parapet walls exceed one meter in height. During parapet construction, cantilevered scaffolding is required for external formwork support. This not only increases construction time and costs, but also poses safety risks and presents significant construction difficulties. To accelerate construction progress and ensure safety, a formwork-free parapet wall construction structure is needed.

[0003] Steel truss floor decks are a composite load-bearing slab composed of welded steel trusses and a base plate. They are widely used in prefabricated steel structures. The steel truss floor deck itself serves as the formwork, eliminating the need for new formwork and the formwork process. Furthermore, it allows for mechanized production, significantly improving labor productivity.

[0004] Therefore, how to design a new parapet wall structure using reinforced truss floor decking to solve the problem of needing to set up cantilever scaffolding for external formwork support during the construction of the above-mentioned parapet wall has become a difficulty in the current construction. Utility Model Content

[0005] The purpose of the utility model is to provide a steel bar truss floor deck parapet construction structure to solve the problems raised in the above background technology.

[0007] In a preferred embodiment, a plurality of steel truss floor decks are arranged in sequence along the horizontal direction, a tie steel bar is provided for every three steel truss floor decks, and two groups of back-to-back connecting angle steels are provided for every six steel truss floor decks. The two groups of connecting angle steels are welded to connect all the steel truss floor decks together.

[0008] In a preferred embodiment, the lower portion of the steel truss floor deck is a 300 mm high guide wall, in which vertical steel bars are arranged, and the vertical steel bars extend into the lower roof panel.

[0009] In a preferred embodiment, roof panel reinforcement bars are arranged in the lower roof panel, and the roof panel reinforcement bars extend and are anchored into the guide wall.

[0010] In a preferred embodiment, a edging steel plate is provided on the outer side of the lower roof panel, which extends upward to cover the lower roof panel. Its covering height is the same as that of the lower roof panel, and the edging steel plate is welded to the outer side of the lower roof panel.

[0011] In a preferred embodiment, the structure of the ground anchor is an inverted U-shape, and a ground anchor is provided at every interval of three steel truss floor decks.

[0012] Compared with the prior art, the beneficial effects of the present invention are:
