[0003] The connection nodes between beams and columns in traditional prefabricated houses are mainly fixed with bolts, so the load will also be concentratedly transmitted through the bolts. Since the load contact area is small, it is easy for stress concentration to form a stress peak at the connection point (the maximum may reach 70% of the yield strength of steel). Fatigue cracks are easily generated in the material in the stress concentration area, which eventually causes fracture. Summary of the invention

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0031] A load-bearing component of a prefabricated house building, comprising:

[0032] Beam column 1, vertical arrangement;

[0033] A crossbeam 2 is arranged transversely and is located above the top of the beam column 1;

[0034] A first steel plate 3 is arranged inside the beam column 1, and a first magnetic block 4 is embedded in the first steel plate 3;

[0035] A second steel plate 5 is arranged inside the cross beam 2, and a second magnetic block 6 is embedded in the second steel plate 5;

[0036] The first limiting plate 7 is fixedly connected to the beam column 1;

[0037] The second limiting plate 8 is fixedly connected to the crossbeam 2;

[0038] Among them, the first limit plate 7 and the second limit plate 8 are both provided with limit holes 9, and the position between the beam column 1 and the cross beam 2 is preliminarily limited by plugging and pulling out the limit holes 9 through the pin 10 adapted to the limit holes 9, and the magnetic force between the first magnetic block 4 and the second magnetic block 6 repel each other.

[0039] Through the above technical scheme, when installing the combination, the vertical beam column 1 is determined, the cross beam 2 is moved to the top of the beam column 1 and the pin 10 is inserted into the limiting holes 9 of the first limiting plate 7 and the second limiting plate 8 at the same time to limit the position between the beam column 1 and the cross beam 2. After the position is limited, the pin 10 is taken out, and the repulsive force between the first magnetic block 4 and the second magnetic block 6 is used as the supporting force of the beam column 1 for the cross beam 2. Compared with the node formed by traditional bolt fixing, the magnetic levitation node in this scheme diffuses the load contact area through the magnetic field repulsion, and the magnetic field evenly distributes the pressure to avoid single-point stress concentration of vertical load.

[0040] A frame 11 is fixedly connected at the node between the crossbeam 2 and the beam column 1 , and the second limit plate 8 is fixedly connected to the outer side of the frame 11 . The inner size of the frame 11 can accommodate the top of the beam column 1 , and an elastic rubber layer 12 is fixedly arranged inside the frame 11 .

[0041] The first steel plate 3 is circular, and is provided with a central groove in the center and a plurality of inclined grooves 13 around the central groove. The first magnetic block 4 is fixedly arranged in the central groove, and a third magnetic block 14 is also fixedly arranged inside each inclined groove 13. The third magnetic block 14 and the second magnetic block 6 have magnetic repulsion each other, and the third magnetic block 14 is arranged equidistantly and tilted relative to the circumference of the second magnetic block 6.

[0042] Through the above technical solution, under the action of wind load or vibration, the node is allowed to produce a horizontal displacement of ±3mm, and the shear force brought to the node by the wind load or vibration is offset by the magnetic repulsion. When the displacement exceeds the ±3mm limit, part of the load is transferred to the beam 1 and the crossbeam 2 through the direct contact between the elastic rubber layer 12 and the beam 1. After the wind load or vibration disappears, it will automatically reset under the action of the magnetic field repulsion.

[0043] A receiving member 15 is fixedly connected inside the beam column 1. The receiving member 15 is provided with a receiving groove 16. The receiving groove 16 receives a spherical body 17. The spherical body 17 can roll 360° without dead angles inside the receiving groove 16. A cavity 18 is provided inside the spherical body 17 to shift the center of gravity of the spherical body 17. The first steel plate 3 is fixedly connected directly above the spherical body 17.

[0044] Through the above technical solution, when the structure is deformed due to temperature changes or foundation settlement, the nodes are allowed to be fine-tuned freely. For example, when the beam column 1 is slightly tilted, the spherical body 17 rolls in the receiving groove 16 while remaining unchanged, maintaining the repulsive force between the magnets, automatically adjusting the direction, and avoiding the additional bending moment caused by the traditional rigid connection of bolts.

[0045] The second steel plate 5 is circular and fixedly connected with a vertical block 19. The cross beam 2 is fixedly connected with a storage block 20 for storing the vertical block 19. The vertical block 19 and the storage block 20 are slidingly connected. The second steel plate 5 and the cross beam 2 are both rotatably connected with a linkage plate 21. The two linkage plates 21 are rotatably connected with the same push plate 22. The position of the second steel plate 5 in the vertical direction can be adjusted by pushing.

[0046] A converter 23 is fixedly connected inside the crossbeam 2, and two sealing pads 24 are sealingly and slidably connected inside the converter 23, one of which is fixedly connected to one pushing end, and the other is fixedly connected to the driving plate 25, and the area between the two sealing pads 24 is filled with liquid.

[0047] The crossbeam 2 is fixedly connected with a cylinder 26, a nut 27 is fixedly arranged inside the cylinder 26, a threaded rod 28 is threadedly connected to the nut 27, one end of the threaded rod 28 is fixedly connected to the driving plate 25, and a groove 29 is provided at the other end. The rotation of the threaded rod 28 is controlled by acting on the groove 29 with an adapted tool.

[0048] Through the above technical solution, the magnetic force of the magnetic levitation node changes, resulting in magnetic loss under long-term load, and the magnetic field will gradually decay. The magnetic field attenuation can be compensated by adjusting the distance between the second magnetic block 6 on the second steel plate 5 and the first magnetic block 4 on the first steel plate 3.

[0049] It should be noted that:

[0050] In order to maintain the magnetic force of the magnet longer, epoxy resin or polytetrafluoroethylene (PTFE) can be used to form a wrapping layer on the first magnetic block 4, the second magnetic block 6 and the third magnetic block 14 to prevent the magnet from directly contacting the steel and causing demagnetization, and rain erosion and dust adsorption and causing magnetic attenuation.

[0051] The arrangement of the magnetic poles of the first magnetic block 4, the second magnetic block 6 and the third magnetic block 14 may follow the following rules:

[0052] The magnetic pole of the first magnetic block 4 is vertically upward (N pole facing upward);

[0053] The magnetic pole of the second magnetic block 6 is vertically upward (S pole facing upward);

[0054] The magnetic pole direction of the third magnetic block 14 is inclined toward the virtual central axis direction of the first steel plate 3 , and the S pole is toward the side close to the first magnetic block 4 .

[0055] The latch 10 is a temporary component and is removed after ensuring that the cross beam 2 is aligned with the beam column 1, leaving only the magnetic suspension support.

[0056] The magnetic suspension bears the vertical load, and the frame 11 and the elastic rubber pad thereon serve as a safety redundancy to prevent falling and limit the displacement range of the magnetic suspension to avoid separation under extreme loads.

[0057] The attached drawings show the node positions of the beam column 1 and the cross beam 2, which are parts of the beam column 1 and the cross beam 2, and do not show the whole picture.

[0058] In the drawings, only one latch 10 is shown at a node, and each of the multiple nodes on the beam 2 has a latch 10 for preliminary positioning.

[0059] Working principle:

[0060] The crossbeam 2 is placed on the beam column 1, and the frame 11 frames the top of the beam column 1. The latch 10 is inserted into the limiting holes 9 of the first limiting plate 7 and the second limiting plate 8 at the same time to perform preliminary positioning between the crossbeam 2 and the beam column 1. After alignment, the latch 10 is removed;

[0061] As the magnetic field decays naturally, the end of the threaded rod 28 containing the groove 29 is rotated by a corresponding tool to make the threaded rod 28 move toward the converter 23, thereby pushing the driving plate 25, and the push plate 22 is moved by the hydraulic drive, which is transmitted to the linkage plate 21 to move the second steel plate 5 containing the second magnetic block 6 downward, thereby reducing the distance between the first steel plate 3 and the second steel plate 5;

[0062] If due to wind load or vibration, the beam 2 will move horizontally relative to the beam 1, and the shear force will be offset by the magnetic field repulsion. When the displacement exceeds the limit, part of the load will be transferred to the structural body on the beam 1 and the beam 2. At the same time, when the first magnetic block 4, the second magnetic block 6 and the third magnetic block 14 are relatively displaced, the magnetic field and the air friction produce a damping effect, consume vibration energy, and further reduce the response of the building structure.

[0063] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
