Embodiment Construction
[0031] figure 1 , figure 2 and image 3 It is a schematic diagram of an embodiment of the connection node of the slot-and-key type prefabricated component of the present invention. The longitudinal edge of the prefabricated concrete component 1 is provided with transverse grooves 2, which are arranged alternately with the protrusions 3; The transverse grooves 2 intersect; the protrusions of the prefabricated components on one side of the node extend into the grooves of the prefabricated components on the other side, and there is at least one longitudinal hole at the near edge of the prefabricated components on both sides that is partially or completely overlapped together to form a superimposed longitudinal Concrete is poured in the superimposed longitudinal hole 5 and the node gap to form a slot-and-key node.
[0032] The connection method of the slot-and-key type prefabricated component connection node is characterized in that it includes the following steps: (1) transpor...

The invention relates to a notch-key type prefabricated member connection node and a connection method thereof, which belong to the technical field of architectural structures. The node comprises prefabricated concrete members and cast-in-place concrete, each prefabricated member is provided with a plurality of vertical through holes parallel with the surface along the length direction, and the vertical edge of the prefabricated member is provided with spaced horizontal notches which intersect outer vertical holes, so that the notches and projections of the edge of the prefabricated member are alternately distributed; the projections of one prefabricated member of the node are inserted into the notches of the other prefabricated member of the node, at least one part or all of the vertical holes of the two prefabricated members are superposed, concrete is poured into the superposed vertical holes, and thereby the notch-key type node is formed. The fabrication method includes the following steps: the prefabricated concrete members are transported to a site and assembled, the notches and projections of the neighboring prefabricated members are engaged with each other, part or all of the vertical holes of the edges of the two members are superposed, concrete is poured into the superposed vertical holes of the two prefabricated members of the node and the node area, and thereby the notch-key type prefabricated member connection node is formed. The notch-key type prefabricated member connection node is used for connecting a prefabricated concrete vertical member with a horizontal member, and can enhance the integrity and structural properties of assembled integrated concrete structures and promote the development of building industrialization.
Description
technical field [0001] The invention belongs to the technical field of engineering structures, and in particular relates to a slot-and-key type prefabricated component connecting node and a connecting method for assembling integral concrete structural components. Background technique [0002] Prefabricated concrete structure is a structural form suitable for industrialization, and it is also the development direction of housing industrialization. The joint connection structure between prefabricated components in precast concrete structures determines the overall performance of the structure. Existing prefabricated concrete structure nodes are generally the weak link of the assembled monolithic structure, which affects the mechanical performance, is easy to crack, and affects the service performance. Contents of the invention [0003] The invention solves the problem of weak joint connection among traditional prefabricated concrete structural components, and provides a slo...
