Description

Technical Field

[0001] The utility model relates to the technical field of node beam splicing, in particular to a prefabricated assembled steel concrete column node beam splicing structure. Background Art

[0002] The prefabricated steel-concrete column node beam splicing structure is a new type of concrete structure system. Its characteristic is that the two materials, steel beams and columns and concrete, are effectively combined to give full play to their respective advantages and make up for each other's shortcomings. In this structure, beams, columns and other components as well as connecting parts are prefabricated in the factory and then assembled and spliced ​​at the construction site.

[0003] The existing prefabricated steel concrete column node beam splicing structure often ignores the importance of vibration reduction effect in design and implementation, which leads to the lack of sufficient resistance of the structure when facing external vibration sources, such as earthquakes, wind, etc. When these vibration sources act on the structure, the splicing between the node beam and the column may produce excessive displacement and stress, which in turn leads to a series of serious consequences, which may cause cracks or even fractures at the splicing, destroying the integrity of the structure, and thus affecting its bearing capacity and service life. Therefore, we propose a prefabricated steel concrete column node beam splicing structure. Utility Model Content

[0004] The purpose of the utility model is to provide a prefabricated steel-concrete column node beam splicing structure to solve the problem that the existing prefabricated steel-concrete column node beam splicing structure mentioned in the above background technology often ignores the importance of vibration reduction effect in design and implementation, which leads to the structure lacking sufficient resistance when facing external vibration sources, such as earthquakes, wind, etc. When these vibration sources act on the structure, the splicing between the node beam and the column may produce excessive displacement and stress, which in turn leads to a series of serious consequences, which may cause cracks or even fractures at the splicing, destroy the integrity of the structure, and further affect its bearing capacity and service life.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a prefabricated and assembled steel-concrete column node beam splicing structure, comprising a steel-concrete column, steel beams are arranged at the top positions on both sides of the steel-concrete column, and the first connecting plates are fixedly connected to the opposite sides of the two steel beams, a fixed plate is fixedly installed at the bottom position of the surface of the steel-concrete column, a movable plate is arranged on the surface of the steel-concrete column corresponding to the upper end of the fixed plate, a rectangular groove is opened inside the movable plate, and steel balls are rollingly installed on the inner wall of the rectangular groove, support rods are fixedly connected at the four corners of the top of the movable plate, a damping rod is fixedly installed on the top of the fixed plate, and a spring is sleeved on the surface of the damping rod.

[0006] Compared with the prior art, the beneficial effects of the utility model are:

[0007] The prefabricated assembled steel-concrete column node beam splicing structure forms an effective vibration reduction system through the design of fixed plates, movable plates, rectangular grooves, damping rods, springs, steel balls and support rods, and the cooperation of fixed plates and movable plates. The steel balls rollingly installed in the rectangular grooves opened inside the movable plates enable the movable plates to slide freely along the outer wall of the steel-concrete columns, while reducing the friction between the movable plates and the columns, thereby allowing the structure to produce a certain degree of adaptive adjustment when external vibrations such as earthquakes occur. When external vibrations act on the steel beam, the portion of the steel beam connected to the steel-concrete column through the first connecting plate will be affected. When the movable plate is subjected to impact, at this time, the support rod is fixedly connected to the lower end of the steel beam through the second connecting plate, which plays a key supporting role and transfers the vibration energy to the movable plate. When the movable plate is subjected to vibration, the damping rod and spring at its bottom will play a role. The damping rod converts the vibration energy into heat energy through the damping material inside it, while the spring absorbs the vibration energy through its own elastic deformation. The two work together to significantly reduce the amplitude and frequency of the vibration, effectively reduce the impact of external vibrations such as earthquakes on the steel beam and the entire structure, improve the seismic performance of the building, and ensure the overall stability and safety of the building.

[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] See also Figure 1-4The utility model provides a technical solution: a prefabricated and assembled steel-concrete column node beam splicing structure, comprising a steel-concrete column 1, steel beams 2 are arranged at the top positions on both sides of the steel-concrete column 1, and the first connecting plates 3 are fixedly connected to the opposite sides of the two steel beams 2, and a fixed plate 4 is fixedly installed at the bottom position of the surface of the steel-concrete column 1, and a movable plate 5 is arranged on the surface of the steel-concrete column 1 corresponding to the upper end of the fixed plate 4, and a rectangular groove 6 is opened inside the movable plate 5, and a steel ball 9 is rollingly installed on the inner wall of the rectangular groove 6, and the top of the movable plate 5 is fixedly connected with a support rod 10 near the four corners, and a damping rod 7 is fixedly installed on the top of the fixed plate 4, and a spring 8 is sleeved on the surface of the damping rod 7.

[0015] The opposite sides of the two first connecting plates 3 are fixedly connected to the outer wall of the steel-concrete column 1 by bolts, so as to connect the steel beam 2 and the steel-concrete column 1 .

[0016] The movable plate 5 is sleeved on the outside of the steel-concrete column 1 through the rectangular groove 6. A plurality of steel balls 9 are provided. The surfaces of the plurality of steel balls 9 are in contact with the outer wall of the steel-concrete column 1, thereby reducing the friction between the movable plate 5 and the steel-concrete column 1 and making the movement of the movable plate 5 smoother.

[0017] The four support rods 10 arranged on both sides are arranged in a symmetrical manner with a left-right tilt, which not only enhances the stability of the structure, but also effectively disperses and transfers the load and reduces the situation where a single point is subjected to excessive force.

[0018] The tops of the four support rods 10 are fixedly connected with second connecting plates 11 , and the four second connecting plates 11 are fixedly connected to the lower ends of the two steel beams 2 respectively through bolts, so as to connect the support rods 10 and the steel beams 2 .

[0019] There are eight damping rods 7 , and the upper ends of the eight damping rods 7 are fixedly connected to the bottom of the movable plate 5 to provide a damping effect, absorb and dissipate vibration energy, and thus reduce the vibration response of the structure.

[0020] The lower end of the spring 8 is fixedly connected to the top of the fixed plate 4, and the upper end of the spring 8 is fixedly connected to the bottom of the movable plate 5. The design function of the spring 8 is to provide elastic support to help the movable plate 5 to perform adaptive adjustment when it is vibrated, thereby protecting the structure from damage.

[0021] Working principle: When the building is subjected to vibration, such as earthquake or other external forces, the vibration reduction function of the prefabricated assembled steel-concrete column node beam splicing structure will start to work. First, the vibration acts on the steel beam 2, and the steel beam 2 produces a small displacement or vibration due to the force. These displacements or vibrations are transmitted to both sides of the steel-concrete column 1 through the fixed connection of the first connecting plate 3 and the bolts. Next, since the steel beam 2 is connected to the top of the movable plate 5 through the support rod 10 and the second connecting plate 11, the vibration energy will be quickly transmitted to the movable plate 5. At this time, the movable plate 5 can perform a small adaptive movement outside the steel-concrete column 1 due to the rectangular groove 6 opened inside and the steel balls 9 rolling on the inner wall. This design allows the movable plate 5 to maintain contact with the steel-concrete column 1 during the vibration process. The close contact of the concrete column 1 reduces friction resistance and makes energy transmission smoother. When the movable plate 5 is subjected to vibration, the damping rod 7 and the spring 8 at the bottom thereof will start to work. The damping rod 7 uses the damping material inside it to convert vibration energy into heat energy, thereby reducing the vibration amplitude. At the same time, the spring 8 absorbs and stores vibration energy through its elastic deformation, thereby reducing the impact on the movable plate 5 and the support rod 10. Under the action of the spring 8, the movable plate 5 can reciprocate up and down during the vibration process, thereby further consuming the vibration energy. This reciprocating motion not only reduces the impact of vibration on the superstructure, but also effectively converts the vibration energy into other forms of energy through the synergistic effect of the damping rod 7 and the spring 8, which is eventually dissipated in the air or converted into heat energy.

[0022] In summary: the prefabricated assembled steel concrete column node beam splicing structure, through the design of the fixed plate 4, the movable plate 5, the rectangular groove 6, the damping rod 7, the spring 8, the steel ball 9 and the support rod 10, the cooperation of the fixed plate 4 and the movable plate 5, forms an effective vibration reduction system, the steel ball 9 rollingly installed in the rectangular groove 6 opened inside the movable plate 5 enables the movable plate 5 to slide freely along the outer wall of the steel concrete column 1, while reducing the friction between the movable plate 5 and the column, thereby allowing the structure to produce a certain degree of adaptive adjustment when external vibrations such as earthquakes occur. When external vibrations act on the steel beam 2, the steel beam 2 is connected to the steel concrete column 1 through the first connecting plate 3. The connected part will be impacted. At this time, the support rod 10 is fixedly connected to the lower end of the steel beam 2 through the second connecting plate 11, playing a key supporting role and transferring the vibration energy to the movable plate 5. When the movable plate 5 is vibrated, the damping rod 7 and the spring 8 at the bottom thereof will play a role. The damping rod 7 converts the vibration energy into heat energy through the damping material inside it, while the spring 8 absorbs the vibration energy through its own elastic deformation. The two work together to significantly reduce the amplitude and frequency of the vibration, effectively reduce the impact of external vibrations such as earthquakes on the steel beam 2 and the entire structure, improve the seismic performance of the building, and ensure the overall stability and safety of the building.
