specific Embodiment approach

[0061] The design goal of using the new type of prefabricated concrete structure plastically controllable steel joints in the present invention is: after using the new type of joints, the dynamic characteristics of the structure under frequent earthquakes are approximately unchanged compared with conventional cast-in-place concrete structures, that is, to ensure normal use The stiffness of the structure remains unchanged, and the damper fully functions under fortification intensity or rare earthquakes, absorbing the structural vibration energy input by the earthquake in a concentrated manner, protecting other parts from entering plasticity or restricting the development of plasticity, and the bearing bears the main shear force to ensure that the joints will not collapse. , so as to achieve controllable plasticity and good energy dissipation performance. The node described in the present invention is different from the existing prefabricated concrete structure. It is completely ...

Abstract

The invention provides prefabricated concrete structure plastic controllable steel joints. An upper column of the prefabricated concrete structure is docked with a lower column of the prefabricated concrete structure through a pre-embedded inner ring steel plate and a pre-embedded outer ring steel plate, and force type steel is connected between the middle of the end faces of the upper column and the lower column; a side plate of the outer ring steel plate is connected with a rectangular steel casting member through a fixing member, the rectangular steel casting member is connected with a radial spherical plain bearing, the radial spherical plain bearing is connected with a concrete beam through the steel casting member, the two sides of a box-type energy dissipation sealing plate damper are connected with the rectangular steel casting member and a steel box-type conversion beam section through bolts correspondingly, and the radial spherical plain bearing is located in the box-type energy dissipation sealing plate damper; and the steel box-type conversion beam section is connected with the concrete beam. According to the technical scheme, the whole process of construction is dry, the construction quality is easy to guarantee, and the steel joints are easy to install and detach, small in environmental pollution, controllable in structural plastic and good in shock resistance.

Description

technical field [0001] The invention belongs to the technical field of node design of prefabricated structures, and in particular relates to a prefabricated assembled concrete structure plastically controllable steel node. Background technique [0002] Prefabricated concrete structures are widely used at home and abroad because of their advantages such as high production efficiency, good component quality, less construction waste, and resource and energy saving. The prefabricated assembly structure is mainly composed of prefabricated components and node connections. To ensure good performance of the structure, the prefabricated assembly structure is required to be safe and reliable on both components and nodes. The prefabricated components are completely processed in the factory, the production working environment is stable, the production process is highly industrialized, and the production quality is strictly controlled, so its product performance is easy to guarantee; how...
