Embodiment Construction
[0047] The implementation of the present invention will be described in detail below in conjunction with the drawings and examples.
[0048] The invention is a self-resetting prefabricated assembly frame, that is, the residual deformation of beams and columns is small after loading, and the self-resetting can basically be realized, and the structure has a certain energy consumption capacity at the same time.
[0049] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 , Figure 7 with Figure 8 shown, which includes:
[0050] Two ordinary concrete columns 12;
[0051] The precast concrete beam 1 is set between two ordinary concrete columns 12, and there are through grooves 10 reserved on the sides of both ends, and the two ends are reserved. The height direction of 12 is all vertical, pours and fills up groove 10 with common concrete after installation;
[0052] The beam-end steel plate connectors are arranged at both ends of the precast concre...

A self-resetting frame structure, that is, a frame structure with a certain overall self-resetting ability, which has small residual deformation after loading, can realize self-resetting, and has a certain energy consumption capacity. Prefabricated concrete beams with post-cast concrete grooves reserved for tensioning prestressed steel strands; steel plate connectors arranged at the two ends of the beam and the connection area on the column; high-strength bolts arranged on the steel plate connectors; The section steel between the steel plate connectors and whose length direction is parallel to the precast concrete beam; the stiffeners perpendicular to the steel plate connectors on the column and the profile steel; the high-strength bolts arranged on the steel plate connectors on the column; The direction is parallel to the prestressed steel strand of the precast concrete beam; the clip-type anchor set at the end of the prestressed steel strand in the reserved groove of the precast concrete beam; and, set on the steel plate connector on the column and in the Low retraction clip anchors at the ends of prestressed steel strands.
Description
technical field [0001] The invention belongs to the technical field of construction, in particular to a self-resetting frame structure and a construction method. Background technique [0002] In recent years, the state has required the development of energy-saving and environmental protection industries to promote the structural transformation of the construction industry, which consumes a lot of energy. The prefabricated structure is a structural form that satisfies the industrialized production mode, meets the national requirements for energy conservation and environmental protection, and is the only way for the industrialization of buildings. Prestressed prefabricated concrete structure, as an important structural form of prefabricated structure, has the advantages of fast construction speed, improved site environment, reliable connection, reduced concrete cracks, easy control of construction quality, etc., and has been fully developed and researched. Among them, the "dr...
