Joint connecting device suitable for assembly type structure

Abstract

The invention discloses a novel joint connecting device suitable for an assembly type structure. The joint connecting device comprises connecting pieces 1, shear-tension resistant anchoring parts 2, connecting plates 3 and connecting bolts 4 and is characterized in that the connecting pieces 1 are combined in a staggered mode and fixed to the connecting plates 3; shear-tension resistant parts are perpendicularly embedded into the connecting pieces 1 and anchored at the outermost connecting pieces 1 to form the shear-tension resistant anchoring parts 2; and each shear-tension resistant part is formed by overlapping metal layers and fiber layers. The novel joint connecting device suitable for the assembly type structure has the four functions of supporting, force transferring, energy consumption and displacement control and is a high-performance joint connecting device, and the four functions are mainly achieved by the core components, namely the shear-tension resistant anchoring parts 2 in the joint connecting device.

Description

technical field [0001] The present invention relates to the field of construction, and in particular to a novel node connection device suitable for prefabricated structures, which can be applied to prefabricated frame structures, prefabricated frame-shear wall structures, prefabricated frame-core tubes in earthquake-prone areas structure. Background technique [0002] The current prefabricated assembly structure, especially the prefabricated assembly concrete structure, in order to meet the requirements of being equivalent to cast-in-place and ensure the overall performance of the prefabricated assembly concrete structure, the joint structure is very complicated, which has caused many difficulties in design, production, and construction. Restricted the development of construction industrialization. [0003] Taking the common prefabricated concrete structure as an example, the four major technical difficulties encountered in the design, construction and use of the current pr...

Problems solved by technology

However, complicated supports will lead to confusion on the construction site and seriously affect the construction progress

[0005] 2) Compared with the cast-in-place concrete structure, the prefabricated concrete structure has relatively weak nodes and integrity

Therefore, when an earthquake occurs rarely, the interstory displacement of the prefabricated concrete structure is difficult to meet the code requirements, resulting in the collapse of the house

However, overly complex node design and structure will greatly increase the difficulty of construction, thus severely restricting the development of building industrialization.
