Embodiment Construction
[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific installation methods. The main components of the structural system include extended longitudinal reinforcement 1, reinforced concrete upper column 2, reinforced concrete lower column 3, H-shaped steel 4, 2 steel plates 7 with bolt holes and 2 sealing plates 10 with grouting holes. The construction sequence of the structure of the present invention As follows:
[0030] 1. In addition to on-site extended longitudinal reinforcement 1, use gasket 5 and nut 6 to tighten on steel plate 7 with bolt holes, and both sides of H-shaped steel 4 are sealed with steel sealing plates 10 with grouting holes, and then grouting through grouting holes 11 In addition, all components are prefabricated in the factory, and the size and spacing of bolt holes 8 reserved on the extended longitudinal bars 1 and steel connectors should meet the structural requirements. The rei...

The invention discloses a detachable assembly type splicing node for reinforced concrete columns by adopting steel connecting pieces. The splicing node mainly comprises a reinforced concrete upper column, a reinforced concrete lower column, steel connecting pieces, outward extending longitudinal ribs and two steel sealing plates with grouting holes, wherein by outwards extending the longitudinal ribs of the reinforced concrete columns, firstly the outward extending longitudinal ribs of the reinforced concrete columns are inserted into bolt holes of the steel connecting pieces and are screwed up by nuts and spacers, then the two sides of the steel connecting pieces are sealed by the steel sealing plates with holes, and grouting is implemented through the grouting holes, so that the reinforced concrete columns can be spliced. When the reinforced concrete columns are changed, the reinforced concrete columns are separated from the steel connecting pieces by cutting the steel sealing plates, cleaning mortar and disassembling the nuts, so that the disassembly and replacement of the upper column and the lower column are realized. According to the splicing node, the all used members are assembled and connected on site, the onsite welding work and template engineering can be reduced, the construction industrialization assembly efficiency can be improved, and a novel energy-saving, environment-friendly and detachable construction concept of the construction members is reflected.
Description
technical field [0001] The invention belongs to the technical field of engineering structures, and is particularly applicable to the field of on-site splicing operations between reinforced concrete columns in multi-high-rise building structures. Background technique [0002] my country's building construction is mainly based on on-site construction. This traditional production method is not highly industrialized, the design and construction are relatively extensive, the quality of construction products is unstable, the construction efficiency is low, the demand for labor is large, the loss of materials and the amount of construction waste And energy consumption is relatively large, can not meet the sustainable development construction requirements of energy conservation and environmental protection. With the acceleration of the process of "construction industrialization and housing industrialization" in our country, the trend of housing industrialization is becoming more and ...
