Description

Technical Field

[0001] The invention belongs to the technical field of prefabricated buildings, and in particular relates to a high-efficiency earthquake-resistant splicing node structure of a prefabricated building. Background Art

[0002] Prefabricated buildings are a type of construction method that uses factory-produced prefabricated components and assembles them on site. Unlike traditional cast-in-place concrete structures, the main feature of prefabricated buildings is that the walls, floor slabs, beams, columns and other components of the building are manufactured in the factory in advance and transported to the construction site for assembly.

[0003] Prefabricated buildings have many advantages. First, since the components are produced in factories, they are less affected by external factors such as weather and have a shorter construction period. Second, factory production can achieve standardized and refined management, the quality of components is more stable, and the construction environment on the construction site can be optimized, reducing pollution such as dust and noise. Third, prefabricated buildings help improve the energy efficiency and environmental protection of buildings, because many prefabricated components can use environmentally friendly materials, reducing the generation of construction waste during construction.

[0004] Although prefabricated buildings are constructed quickly, they still have to meet the earthquake resistance requirements of the building. In the installation process of existing prefabricated building structures, structural parts such as curtain walls and load-bearing columns will be cast a second time after splicing to improve the connection strength of the assembled structural parts. However, the stairs, as an important component connecting the upper and lower floors, are only assembled with a few connecting steel bars, so the vibration of the floors can easily cause the prefabricated stairs to break, affecting the earthquake resistance of the prefabricated stairs. Summary of the invention

[0005] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide an efficient seismic-resistant splicing node structure for prefabricated buildings to solve the problem that the existing connection method between prefabricated stairs and floors will reduce the seismic performance of the prefabricated stairs.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Embodiment 1:

[0030] See also Figure 1 - Figure 7 As shown, the high-efficiency earthquake-resistant splicing node structure of the prefabricated building includes:

[0031] A housing 1, wherein a mounting hole 2 is formed on the housing 1, and mounting bolts 3 are provided inside the mounting hole 2, and the housing 1 is mounted on a building through the mounting bolts 3;

[0032] A cushion layer, arranged inside the housing 1, consisting of a first cushion layer 4 for buffering lateral vibration and a second cushion layer 5 for buffering longitudinal vibration;

[0033] The connecting assembly 6 is arranged in the middle of the second cushion layer 5 and is used to connect the structural parts to be assembled.

[0034] As can be seen from the above, by changing the connection mode between the prefabricated staircase and the floor, a first cushion layer 4, a second cushion layer 5 and a connecting component 6 are arranged inside the shell 1, and the prefabricated staircase and the shell 1 are connected together through the connecting component 6. The vibration of the floor will be absorbed by the first cushion layer 4 and the second cushion layer 5, and the connecting component 6 can also absorb a part of the vibration energy to a certain extent, which can effectively reduce the vibration energy transmitted from the floor to the prefabricated staircase, avoid the prefabricated staircase from receiving too much vibration energy and causing fracture, and effectively enhance the seismic resistance of the prefabricated staircase, so that even if the prefabricated staircase receives part of the vibration energy, it will not affect the normal use

[0035] See also Figure 5 As shown, the first cushion layer 4 is composed of a left cushion block 41 and a right cushion block 42, and the left cushion block 41 and the right cushion block 42 are both arranged in a triangular shape, and the inclined surfaces of the left cushion block 41 and the right cushion block 42 are both provided with a stepped connecting tooth 43, and the two side surfaces of the stepped connecting tooth 43 are respectively inclined to the horizontal plane and the vertical plane.

[0036] When the first cushion layer 4 receives lateral vibration, the left cushion block 41 and the right cushion block 42 will be squeezed and interlaced with each other, and the stepped connecting teeth 43 between the two cushion blocks will rub and interlace with each other. At this time, the kinetic energy of the vibration will be converted into other forms of energy such as heat energy, thereby consuming the energy of the lateral vibration. Since the left cushion block 41 and the right cushion block 42 are both inclined, after the left cushion block 41 and the right cushion block 42 are subjected to force and interlaced, they will return to their original positions under the action of gravity and have a certain self-recovery property.

[0037] The left pad 41 and the right pad 42 are both made of shock-absorbing rubber material to bear the weight of the stairs and to alleviate the up and down vibration of the stairs to a certain extent. The step connecting teeth 43 are made of steel material to enhance the friction surface of the pads and avoid damage to the pads.

[0038] See also Figure 6 As shown, the second cushion layer 5 is composed of an upper cushion plate 51 and a lower cushion plate 52 , and a middle steel plate 53 arranged in a wave shape is sandwiched between the upper cushion plate 51 and the lower cushion plate 52 .

[0039] When the second cushion layer 5 is subjected to longitudinal compression, the longitudinal kinetic energy will be transmitted to the upper pad 51, the lower pad 52 and the middle steel plate 53 at the same time. Since the middle steel plate 53 is arranged in a wavy shape, after the upper pad 51 and the lower pad 52 are attached to the middle steel plate 53, the upper pad 51 and the lower pad 52 close to the middle steel plate 53 will also present a wavy surface. At this time, when the pad and the middle steel plate 53 are compressed, the upper pad 51, the lower pad 52 and the middle steel plate 53 will be compressed and deformed. During the compression and deformation process, the upper pad 51 and the lower pad 52 will convert the kinetic energy into other forms of energy such as friction heat energy, thereby absorbing and reducing the transmitted longitudinal vibration energy, and the elastic potential energy stored in the deformed middle steel plate 53 will drive the middle steel plate 53 to reset. At this time, the middle steel plate 53 will drive the upper pad 51 and the lower pad 52 to reset together, and have a certain self-recovery performance.

[0040] The upper pad 51 and the lower pad 52 are both made of polytetrafluoroethylene or shock-absorbing rubber. When the upper pad 51 and the lower pad 52 are squeezed, the kinetic energy is converted into other forms of energy such as heat energy, thereby reducing the vibration energy transmitted to the prefabricated stairs.

[0041] Embodiment 2:

[0042] See also Figure 1 - Figure 7 As shown, the high-efficiency earthquake-resistant splicing node structure of the prefabricated building includes:

[0043] A housing 1, wherein a mounting hole 2 is formed on the housing 1, and mounting bolts 3 are provided inside the mounting hole 2, and the housing 1 is mounted on a building through the mounting bolts 3;

[0044] A cushion layer, arranged inside the housing 1, consisting of a first cushion layer 4 for buffering lateral vibration and a second cushion layer 5 for buffering longitudinal vibration;

[0045] The connecting assembly 6 is arranged in the middle of the second cushion layer 5 and is used to connect the structural parts to be assembled.

[0046] As can be seen from the above, by changing the connection mode between the prefabricated staircase and the floor, a first cushion layer 4, a second cushion layer 5 and a connecting component 6 are arranged inside the shell 1, and the prefabricated staircase and the shell 1 are connected together through the connecting component 6. The vibration of the floor will be absorbed by the first cushion layer 4 and the second cushion layer 5, and the connecting component 6 can also absorb a part of the vibration energy to a certain extent, which can effectively reduce the vibration energy transmitted from the floor to the prefabricated staircase, avoid the prefabricated staircase from receiving too much vibration energy and causing fracture, and effectively enhance the seismic resistance of the prefabricated staircase, so that even if the prefabricated staircase receives part of the vibration energy, it will not affect the normal use

[0047] See also Figure 5As shown, the first cushion layer 4 is composed of a left cushion block 41 and a right cushion block 42, and the left cushion block 41 and the right cushion block 42 are both arranged in a triangular shape, and the inclined surfaces of the left cushion block 41 and the right cushion block 42 are both provided with a stepped connecting tooth 43, and the two side surfaces of the stepped connecting tooth 43 are respectively inclined to the horizontal plane and the vertical plane.

[0048] When the first cushion layer 4 receives lateral vibration, the left cushion block 41 and the right cushion block 42 will be squeezed and interlaced with each other, and the stepped connecting teeth 43 between the two cushion blocks will rub and interlace with each other. At this time, the kinetic energy of the vibration will be converted into other forms of energy such as heat energy, thereby consuming the energy of the lateral vibration. Since the left cushion block 41 and the right cushion block 42 are both inclined, after the left cushion block 41 and the right cushion block 42 are subjected to force and interlaced, they will return to their original positions under the action of gravity and have a certain self-recovery property.

[0049] The left pad 41 and the right pad 42 are both made of shock-absorbing rubber material to bear the weight of the stairs and to alleviate the up and down vibration of the stairs to a certain extent. The step connecting teeth 43 are made of steel material to enhance the friction surface of the pads and avoid damage to the pads.

[0050] See also Figure 6 As shown, the second cushion layer 5 includes an upper cushion plate 51 and a lower cushion plate 52 , and a middle steel plate 53 arranged in a wave shape is sandwiched between the upper cushion plate 51 and the lower cushion plate 52 .

[0051] When the second cushion layer 5 is subjected to longitudinal compression, the longitudinal kinetic energy will be transmitted to the upper pad 51, the lower pad 52 and the middle steel plate 53 at the same time. Since the middle steel plate 53 is arranged in a wavy shape, after the upper pad 51 and the lower pad 52 are attached to the middle steel plate 53, the upper pad 51 and the lower pad 52 close to the middle steel plate 53 will also present a wavy surface. At this time, when the pad and the middle steel plate 53 are compressed, the upper pad 51, the lower pad 52 and the middle steel plate 53 will be compressed and deformed. During the compression and deformation process, the upper pad 51 and the lower pad 52 will convert the kinetic energy into other forms of energy such as friction heat energy, thereby absorbing and reducing the transmitted longitudinal vibration energy, and the elastic potential energy stored in the deformed middle steel plate 53 will drive the middle steel plate 53 to reset. At this time, the middle steel plate 53 will drive the upper pad 51 and the lower pad 52 to reset together, and have a certain self-recovery performance.

[0052] The upper pad 51 and the lower pad 52 are both made of polytetrafluoroethylene or shock-absorbing rubber. When the upper pad 51 and the lower pad 52 are squeezed, the kinetic energy is converted into other forms of energy such as heat energy, thereby reducing the vibration energy transmitted to the prefabricated stairs.

[0053] See also Figure 3 - Figure 4As shown, the connecting component 6 is inserted into the installation groove in the middle of the second cushion layer 5, and the connecting component 6 includes an outer cylinder 61 and an intermediate rod 62 inserted in the middle of the outer cylinder 61, and a butt ring 63 is sandwiched between the outer cylinder 61 and the intermediate rod 62. The butt ring 63 is arranged in a wavy ring shape, and the inner and outer walls of the butt ring 63 are respectively abutted against the intermediate rod 62 and the outer cylinder 61, and a sealing plate 64 is fixedly connected to the top of the outer cylinder 61. The outer cylinder 61, the intermediate rod 62 and the butt ring 63 are all made of steel material.

[0054] The middle rod 62 can be inserted into the prefabricated staircase, and the vibration of the floor will be transmitted to the connecting component 6 after being filtered by the first cushion layer 4 and the second cushion layer 5. At this time, the outer tube 61 will be displaced under the action of the vibration energy, and the displaced outer tube 61 will squeeze the ring 63, causing the ring 63 to deform. Friction is generated between the ring 63, the outer tube 61 and the middle rod 62, which prolongs the vibration transmission time to a certain extent, avoiding the prefabricated staircase from receiving more vibration energy in a short time and breaking, thereby providing effective protection for the prefabricated staircase. The top sealing plate 64 can be made of some elastic materials, such as hard rubber, engineering plastics, etc. It should be noted that a gap should be left between the middle rod 62 and the outer shell 1 for the middle rod 62 to move.

[0055] Fine sand is filled between the butt ring 63 and the outer tube 61 , and between the butt ring 63 and the middle rod 62 . The fine sand acts as a medium that can effectively delay the deformation tendency of the butt ring 63 , thereby enhancing the anti-seismic buffering performance of the butt ring 63 .

[0056] See also Figure 7 As shown, an upper mounting pad 7 arranged in an arc shape is connected to the bottom of the second cushion layer 5, a lower mounting pad 8 is fixedly connected to the inside of the outer shell 1, and the upper mounting pad 7 is clamped in the lower mounting pad 8, and the upper mounting pad 7 and the lower mounting pad 8 are both made of steel material.

[0057] When the second cushion layer 5 is squeezed by the vibration force, no matter from which direction the squeezing force is transmitted, the vibration force will drive the second cushion layer 5 and the upper mounting pad 7 to slide in the lower mounting pad 8. At this time, since the upper mounting pad 7 and the lower mounting pad 8 are both arranged in an arc shape and are engaged with each other, when the vibration force disappears, the upper mounting pad 7 will slide back to the middle of the lower mounting pad 8, thereby driving the second cushion layer 5 to reset, so that the structure has a certain self-recovery property. In some small earthquakes, even if the prefabricated stairs are vibrated and have some displacement, the connection nodes disclosed in the present device can also help the prefabricated stairs to reset, thereby restoring the normal use function of the stairs.
