Description

The present invention relates to the field of house construction, and more particularly to a kind of beam column node structure and a prefabricated house.

According to the data, China has been the largest building in the world every year since the reform opening, the largest consumption of cement steel in the world, the largest amount of building waste produced, Has an average life span of only 25-30 years. And China has a large countryside, and based on tradition, people of every generation build new homes under great economic burden. At this time, an old house that was consumed and built by a large number of people of the previous generation becomes waste and has no value. Repeated in this way, the life of rural houses was short and the pressure on environmental resources was great, and it brought great economic pressure to the residents. At present, the urban and rural construction methods in China are rough, energy resources are high, and utilization efficiency is low. There is a problem that importance is placed on the scale and the efficiency is neglected, the appearance is emphasized and the quality is neglected, the architecture is emphasized and the management is neglected, and the service life of the architecture is much lower than the design life. It is necessary to promote urban and rural construction on ecological, recycling and low-carbon scientific development lines in accordance with the actual situation, and promote full-scale, cooperative and sustainable development of economic society.

Based on the results of current material science and connection technology, there is already a connection technology condition to realize a building structure of “all assembly and dismantling”, and some scholars also believe that “dry connection” will be the main future of prefabricated prefabricated concrete structures. I think this is one direction of development and research. There are relatively few research results on “dry connection”, especially fewer prefabricated prefabricated concrete node connection methods for “all assembly and disassembly”, and there are many problems that need to be studied. Some people describe the prefabricated concrete structure as “building a house to play with building blocks, building a house to make a car”. The current attention is on “assembly”, and there is little attention on the subsequent “disassembly and replacement”.

Most current prefabricated concrete structures have complicated beam-column connection locations, making the construction difficult, and at the same time the load on the node position is large and complex, and the nodes weaken the entire frame-assembled concrete structure. At present, the focus on research and application of nodes is on-site (wet connection), and mainly to achieve the design goal of “strong nodes”, the structural seismic design of “strong pillar weak beam, strong node weak members” Embody basic principles.

When an earthquake occurs and the house beam and the house column rotate relative to each other, for example, when the house beam rotates up, the house beam rotates upward or the tendency to rotate is the first connecting plate The first connecting plate rotates upward with the outer arc plate, the outer arc plate pushes the connecting steel plate and rotates along the axis of the slide rotation axis, and at the same time the connecting steel plate is relative to the slide rotation axis. Slide. Furthermore, a relative angular displacement occurs between the rotating steel plate and the viscoelastic material layer, and a relative angular displacement occurs between the shear steel plate, the rotating steel plate, and the viscoelastic material layer, and the viscoelastic material layer is deformed. The viscoelastic material layer is deformed between the rotating steel plate and the shearing steel plate to absorb the seismic energy and obtain an impact absorbing effect. The outer plate is fixed to the first connecting plate, and the outer plate and the viscoelastic material layer on the foreground are intimately connected to each other. The material layer is deformed and a better shock absorbing effect is obtained.

Also, when the house column rotates down, the house column rotates downward or the rotation tendency causes the second connection plate to rotate down, and the second connection plate moves down with the shear steel plate and the inner arc plate. The inner arc plate pushes the connecting steel plate and rotates along the axis of the slide rotation shaft, and at the same time the connecting steel plate slides relative to the slide rotation shaft. A relative angular displacement occurs between the shear steel plate, rotating steel plate, and viscoelastic material layer, the viscoelastic material layer is deformed, the viscoelastic material layer is deformed between the rotating steel plate and the shear steel plate, and seismic energy is reduced. Absorb and get shock absorption effect. Since the inner plate is fixed to the second connecting plate and the inner plate and the viscoelastic material layer on the rearmost surface are closely connected to each other, the inner plate is rotated by the rotation of the second connecting plate, and the viscoelastic material on the rearmost surface is rotated. The layer is deformed and a better shock absorbing effect is obtained.

There is a sufficient gap between the outer plate and the second connecting plate, and there is a sufficient gap between the inner plate and the first connecting plate, so when an earthquake occurs, the outer plate does not contact the second connecting plate, and the inner plate A failure of the damper can be avoided without contacting the first connecting plate.

This damper has an expansion effect, and if a single point angular displacement occurs between the first connecting plate and the second connecting plate, a considerably large relative angular displacement occurs between the rotating steel plate and the viscoelastic material layer through the rotation of the rotating steel plate. In other words, the displacement between the rotating steel plate and the viscoelastic material layer is enlarged, and a better shock absorbing effect is obtained.
