Problems solved by technology

However, when strong earthquakes occur in prefabricated reinforced concrete structures, the ductility of beam-column self-resetting joints tends to be small and the plastic deformation is large, resulting in cracks, breakage or even collapse of concrete components, which makes post-earthquake repair work difficult or even dangerous. can not fix

Embodiment 1

[0037] See attached figure 1 , The embodiment of the present invention discloses a prefabricated seismic ductile reinforced concrete frame structure, which is constructed on a concrete foundation 3, including: reinforced concrete column 2, anchor rod 16, reinforced concrete beam 1, tie rod 7 and damper 12;

[0038] The reinforced concrete column 2 is arranged vertically, and the bottom end is inserted into the groove formed on the top surface of the concrete foundation 3, and elastic stretchable material 14 is filled between the reinforced concrete column 2 and the groove; the reinforced concrete column 2 is close to the end of the concrete foundation 3 With holes 4;

[0039] The anchor rod 16 passes through the inside of the reinforced concrete column 2 axially, the top end passes through the hole 4 of the reinforced concrete column 2 and is fixed with a disc spring set 5, and the other end passes through the bottom of the reinforced concrete column 2 and is fixed inside the concr...

Embodiment 2

[0055] The difference between this embodiment and the first embodiment is: the position of the hole 4 at the foot end of the reinforced concrete column 2 is different, the opening position is on the left and right sides of the foot end, and the end of the reinforced concrete beam 1 is open The position of the hole 4 is still on the front and rear sides of the beam end; the end of the reinforced concrete column 2 can be replaced with externally installed in order to ensure that the reinforced concrete column 2 is not damaged by bending. Steel pipe protection. During construction, adaptive selection can be made according to specific conditions, with the purpose of making the construction method more convenient.

Embodiment 3

[0057] The embodiment of the present invention discloses a method for constructing a seismically ductile reinforced concrete column and a steel reinforced concrete beam frame, which includes the following steps:

[0058] S1, reinforced concrete beam 1, reinforced concrete column 1, with reserved holes 6 and 4 when prefabricated;

[0059] S2. Pre-bury and fix one end of the anchor rod 16 in the concrete foundation 3, design and reserve the size of the groove, and then pour the concrete foundation 3 into shape. After the concrete foundation 3 reaches the final setting stage, fill the grooves with elastic and stretchable. Sexual material 14;

[0060] S3. Pass the reinforced concrete column 2 through the extended end of the embedded anchor rod 16 and put it into the reserved groove of the concrete foundation 3, and install and fix the disc spring set 5 on the anchor rod 16 extending into the hole 4 top;

[0061] S4. Insert the tie rod 7 at the beam-column node into the reserved hole 6 in...

Abstract

The invention discloses a prefabricated assembly-type seismic toughness reinforced concrete frame structure and a construction method. The frame structure is constructed on the basis of concrete and comprises a reinforced concrete column, an anchor rod, a reinforced concrete beam, a pull rod and a damper. According to the prefabricated assembly-type seismic toughness reinforced concrete frame structure, a hole is formed in each of the reinforced concrete column and the reinforced concrete beam, a disc spring group is installed in each hole, the disc spring groups are fixedly connected with beam and column joints through the pull rod and fixedly connected with column and foundation joints through the anchor bolt, densified stirrups or spiral stirrups or exterior steel plates are arranged atthe ends of the reinforced concrete beam and the reinforced concrete column correspondingly, the damper is arranged on the lower side of the beam end, the periphery of the gaps of reserved grooves ofthe reinforced concrete column and a concrete foundation is filled with an elastic scalable material, the ductility of the seismic toughness frame structure is high, the aftershock residual displacement is low, an aftershock main structure basically keeps elastic, and the prefabricated assembly-type seismic toughness reinforced concrete frame structure can be widely used in building structures.

Description

Technical field [0001] The invention relates to the technical field of seismic structural systems, and more specifically to a prefabricated assembly type seismic toughness reinforced concrete frame structure and a construction method. Background technique [0002] In recent years, prefabricated structures have attracted more and more attention from the industry as an energy-saving, environmentally friendly and convenient construction method. The prefabricated structure has the advantages of high efficiency, high degree of industrialization, high degree of standardization, high seismic performance of buildings, and high energy-saving performance. However, prefabricated reinforced concrete structures often have small ductility and large plastic deformation of the beam-column self-resetting joints when a strong earthquake occurs, which leads to cracks, fractures or even collapses in the concrete components, which makes post-earthquake repair work difficult or even unable to repair....
