Example Embodiment

[0018] The present invention will be described in detail below in conjunction with the technical solution and with reference to the drawings.

[0019] The fully assembled cross concrete composite node proposed by the present invention is as Figure 1~Figure 3 Shown.

[0020] The whole device is mainly composed of precast concrete column 1, precast concrete beam-column node core area 2, precast concrete beam 3, precast concrete beam upper terrace 4, precast concrete beam lower terrace 5, precast concrete beam lower steel plate 6, precast concrete column It is composed of longitudinal reinforcement 7, precast concrete column stirrup 8, precast concrete beam penetrating steel plate 9, concrete beam assembly vertical screw hole 10, and concrete beam assembly horizontal screw hole 11. The precast concrete beam penetrating steel plates 9 all pass through the precast concrete beam-column node core area 2 and are welded into a well-shaped shape. The precast concrete beam penetrating steel...

Abstract

The invention provides a full-fabricated cross concrete combining joint which is mainly composed of a precast concrete column, a precast concrete beam column joint core area, precast concrete beams, precast concrete beam upper halfpaces, precast concrete beam lower halfpaces, precast concrete beam lower steel plates, precast concrete beam center penetrating steel plates and the like. All the precast concrete beam center penetrating steel plates pass through the precast concrete beam column joint core area and are welded to be in the shape of a Chinese character 'jing', and the precast concrete beams are mainly divided into the precast concrete beam upper halfpaces, the precast concrete beam lower halfpaces and concrete-free sections. The full-fabricated cross concrete combining joint has the advantages of being high in bearing capacity, good in plasticity and tenacity, convenient to construct, good in economic effect and the like, and construction speed is high. The full-fabricated cross concrete combining joint can be suitable for the requirement that a modern engineering structure develops towards a large span, towering and heavy loading and bears serious conditions, and meets the requirement for modern construction technology industrialization.

Description

technical field [0001] The invention relates to a novel node of a building structure, in particular to a fully assembled cross-shaped concrete composite node of a prefabricated concrete structure. Background technique [0002] Prefabricated concrete buildings refer to prefabricated concrete components produced in factories. Concrete structure housing buildings designed and constructed through on-site assembly. The assembly methods of components generally include on-site post-casting laminated layer concrete, steel bar anchoring and post-casting concrete connection, etc. The steel bar connection can be connected by sleeve grouting connection, welding, mechanical connection and lap connection of reserved holes. In the 1980s, prefabricated prefabricated large-slab houses, which were popular in my country, had many hidden dangers and defects that affected structural safety and normal use due to poor structural integrity, leakage, and floor cracks, and were gradually replaced by...
