Connecting structure and connecting method of skeleton type exterior enclosure wall and main body

Abstract

The invention discloses a connecting structure and a connecting method of a skeleton type exterior enclosure wall and a body. The connecting structure includes skeleton vertical columns, support seatthrough connecting pieces and built-in fittings, the built-in fittings are pre-buried in main body floors, and connecting lug plates of the built-in fittings are located outside the body. One ends ofthe support seat through connecting pieces are in rigid connection with the skeleton vertical columns, and the other ends of the support seat through connecting pieces are fixedly connected with the connecting lug plates. A vertical column support seat connecting method with the advantages of reliable force transferring, simple structure and convenient construction is provided for an exterior enclosure system of a prefabricated building through the improvement of the connecting design of support seat joints of the skeleton vertical columns.

Description

technical field [0001] The invention relates to the field of construction, in particular to a connection structure and connection method between a skeleton type peripheral protective wall and a main body. Background technique [0002] The design of the skeleton-type outer enclosure wall of the prefabricated building mainly includes the design of the skeleton member (column) and the connection design. The connection between the column and the main body is an important link in the structural design of the outer enclosure system. In the curtain wall engineering design, the curtain wall design is an independent special design, mainly considering the economics of a single project, not considering the rationality of related professional design, especially in the design of column supports, different structural forms, the main structure and support pre-design Embedded effects are also different. Commonly used column structure models include single-span structure, or double-span (lo...

Problems solved by technology

[0011] For the calculation results of the above three commonly used column structure models, it can be seen from Table 1-Table 3 that: ① the reaction force of the support of the single-span beam structure in the story is uniform, but the column cross-section is relatively large, which costs more materials; ② the double-span in the story The reaction force coefficient of the beam structure support changes the most, and the embedded parts are not fully utilized; ③The reaction force of the middle support of the double-span beam structure in the story (acting on the lower part of the beam) will have a torsion effect on the main structure floor beam, which will affect the main structure (or Anchorage components) are safe; ④ three calculation models, after comparative analysis of safety and economy, it is advisable to choose a single-support multi-span hinged continuous beam structure; , and the damage of local components or supports will cause the failure of the model mechanism and continuous damage
