Embodiment 1

[0023] Such as Figures 1 to 4 As shown, a ribbed concrete member includes a steel plate 1 rolled as a whole. The steel plate 1 encloses a hollow part that runs through both ends and a member with a closed cross section, such as a column or a plate. The steel plate 1 is provided with a hollow Concrete 1.4 is provided in the hole 1.1 and the rib, the hollow part and the hollow hole 1.1. The rib includes at least two rows of longitudinal ribs 1.3 arranged vertically and at least one row of transverse ribs 1.2 arranged transversely. Between them, the longitudinal rib 1.3 is located between two vertically adjacent holes 1.1 or between the hole 1.1 and the side of the steel plate 1, and the positions of the transverse rib 1.2 and the longitudinal rib 1.3 are aligned. Specifically, the continuous steel strip along the long direction is the longitudinal rib 1.3, which acts as the reinforced steel bar in the reinforced concrete structure; When the rib steel is processed or the struct...

Embodiment 2

[0028] Such as image 3 and 4 As shown, a ribbed concrete member, the member includes four steel plates 1, the four steel plates 1 are tailor-welded into a column or beam with a rectangular cross-section, a hollow interior, and a hollow penetrating through both ends, and the hollow part and the hole Concrete is poured to form ribbed concrete members.

[0029] Other structures are with embodiment 1.

Abstract

The invention provides a rib steel concrete member which comprises a steel plate, the steel plate is enclosed to form a member with a hollow interior, the steel plate is provided with a hollow hole and a rib, and concrete is arranged in the hollow part and the hollow hole. The rib steel concrete member has the advantages that the steel with the best stress performance and external force damage resistance is distributed at the periphery of the member, the concrete with the main compression resistance is wrapped in the middle, and the hollow hole part of the rib steel is also filled with the concrete, so that the rib steel and the concrete are mutually embedded within the range to form a good integral load-bearing member; the rib steel replacing steel bars in the reinforced concrete member is distributed on the outermost side (such as four corners of a rectangular member) of the rib steel member, so that the stress effect of the steel material can be exerted to the maximum extent, core-spun concrete is only pressed and has no cracks, and the four corners which are easily touched by external force are the rib steel and have no damage danger.

Description

technical field [0001] The invention relates to an assembled building component, in particular to a ribbed concrete component. Background technique [0002] Prefabricated reinforced concrete structure is one of the important directions for the development of building structures. It is conducive to the development of building industrialization, improving production efficiency and saving energy, developing green and environmentally friendly buildings, and is conducive to improving and ensuring the quality of construction projects. Compared with the cast-in-place construction method, the prefabricated PC structure is conducive to green construction, because the prefabricated construction can better meet the requirements of green construction, such as land saving, energy saving, material saving, water saving and environmental protection, and reduce the negative impact on the environment. Including reducing noise, preventing dust, reducing environmental pollution, clean transport...
