DETAILED DESCRIPTION

[0032] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0033] Example 1: Reference Figure 1-Figure 13 A beam-column connection node device for assembled buildings comprises: a column 1, a mounting plate 2, a sleeve 3, a crossbeam 4, a lifting mechanism 5 and a bolt 6. The column 1 is connected to the mounting plate 2, the mounting plate 2 is connected to the sleeve 3, the sleeve 3 is inserted with the crossbeam 4, the crossbeam 4 is connected with the lifting mechanism 5, the output end of the lifting mechanism 6 is connected to a plurality of bolts 6, the end of the bolt 6 passing through the side wall of the sleeve 3 is connected to a nut, and the bottom of the nut is in contact with the side wall of the sleeve 3.

[0034] The principles and beneficial effects of the above scheme are:

[0035] The mounting plate 2 is connected to the side wall of the column, and a sleeve 3 is installed on the mounting plate 2. The sleeve 3 is plugged into the crossbeam 4. A lifting mechanism 5 is set in the crossbeam 4. A plurality of bolts 6 are connected to the lifting mechanism 5. The tops of the bolts 6 extend out of the side wall of the sleeve 3. The lifting mechanism 5 can be used to quickly use a plurality of bolts 6 to preliminarily fix the sleeve 3 and the crossbeam 4. Then, the sleeve 3 and the crossbeam 4 are fixed by rotating nuts on the bolts 6. Therefore, the connection and installation efficiency is greatly improved during the installation of the device. At the same time, since the sleeve 3 and the crossbeam 4 are preliminarily connected by a plurality of bolts 6, the phenomenon that some bolts 6 cannot be installed due to uneven force between the sleeve 3 and the crossbeam 4 when the bolts 6 are installed one by one is avoided.

[0036] Example 2: Reference Figure 1-Figure 13 The lifting mechanism 5 includes: a power mechanism 7, a lifting plate 8, a vertical plate 9, a spline tube 10 and a connecting rod 11. The inner wall of the end of the cross beam 4 is connected to the vertical plate 9, and a spline hole is opened in the middle of the vertical plate 9. The spline hole is slidably connected to the spline tube 10. Each inner wall of the cross beam 4 is in contact with a lifting plate 8. The bottom end of the bolt 6 is connected to the lifting plate 8. The side wall of the spline tube 10 is hinged with the bottom ends of multiple connecting rods 11. The top of the connecting rod 11 is hinged with the top of the lifting plate 8. The side wall of the lifting plate 8 is slidably matched with the vertical plate 9. The inner wall of the spline tube 10 is threadedly connected to the power mechanism 7, and the power mechanism 7 is connected to the inner wall of the cross beam 4.

[0037] The principles and beneficial effects of the above scheme are:

[0038] When the height of the bolt 6 needs to be adjusted, the driving mechanism 7 is used to drive the spline tube 10 to move forward or backward. When the spline tube 10 moves forward or backward, the spline hole guides the movement of the spline tube 10, and the synchronous connecting rod 11 rotates clockwise or counterclockwise. Therefore, under the guidance of the vertical plate 9, the lifting plate 8 can rise or fall inside the cross beam 4, thereby driving the bolt 6 to move upward or downward. By setting the connecting rod 11 to be hinged to the lifting plate 8 and the spline tube 10 respectively, the vertical plate 9 guides the movement of multiple lifting plates 8, which not only increases the stability of the mechanism during operation but also improves the synchronization of the movement of the bolt 6.

[0039] Example 3: Reference Figure 1-Figure 13The power mechanism 7 includes: a screw 12, a storage tube 13, a rotating shaft 14, a bevel gear 15, a second bevel gear 16 and a second rotating shaft 17. The inner wall of the spline tube 10 is threadedly connected to the end of the screw 12, the other end of the screw 12 is connected to the end of the storage tube 13, the other end of the storage tube 13 is connected to the end of the rotating shaft 14, the rotating shaft 14 is rotatably connected to the inner wall of the beam 4, the other end of the rotating shaft 14 is connected to the bevel gear 15, the bevel gear 15 is meshed and linked with the second bevel gear 16, the second bevel gear 16 is installed at the end of the second rotating shaft 17, the second rotating shaft 17 is rotatably connected to the beam 4, and the other end of the second rotating shaft 17 passes through the side wall of the beam 4.

[0040] The principles and beneficial effects of the above scheme are:

[0041] When it is necessary to drive the movement of the spline tube 10, the rotating shaft 17 can be rotated outside the cross beam 4, and the bevel gear 16 rotates synchronously, and the bevel gear 15 meshing with it rotates in the opposite direction. The bevel gear 15 drives the rotating shaft 14, the storage tube 13 and the screw 12 to rotate in the opposite direction, thereby moving the spline tube 10. Since the other end of the rotating shaft 17 is arranged outside the cross beam 4, the arrangement of components inside the device greatly saves space and avoids damage to the device before installation, that is, the cross beam 4 effectively protects the entire mechanism.

[0042] Example 4: Reference Figure 1-Figure 13 The end of the screw rod 12 is provided with an end of a circular hole 18, and the other end of the circular hole 18 is provided on the inner wall of the storage tube 13. The mounting hole on the inner wall of the spline tube 10 is slidably connected with an electrode column 19, and the tip of the electrode column 19 is arranged toward the circular hole 18. The spline tube 10 is plugged into and matched with the socket on the mounting seat 2, and the electrode column 19 is installed in the socket. The other end of the electrode column 19 passes through the outside of the mounting seat 2, and the diameter of the tip of the electrode column 19 is smaller than the inner diameter of the circular hole 18. The storage tube 13 is filled with thermite powder.

[0043] The principles and beneficial effects of the above scheme are:

[0044] During the installation of the device, the rise of the lifting plate 8 requires the rotation of the screw 12, so the spline tube 10 moves toward the vertical plate 9, and the circular hole 18 is connected to the storage tube 13. The thermite powder in the storage tube 13 can enter the spline tube 10 through the circular hole 18.

[0045] Example 5: Reference Figure 1-Figure 13An exhaust pipe 21 is connected to the inner wall of the spline tube 10, and a pressure relief column 22 is slidably connected in the exhaust pipe 21. A plurality of exhaust grooves are longitudinally opened on the side wall of the pressure relief column 22. The top of the pressure relief column 22 is connected to the bottom end of a sealing disk 23. The bottom end of the sealing disk 23 is sealed with the top of the exhaust pipe 21. A spherical plug 24 is connected to the top of the sealing disk 23. A spring 25 is connected to the bottom end of the spherical plug 24. The bottom end of the spring 25 is connected to the top of the exhaust pipe 21. The spherical plug 24 is plugged into a spherical slot. The spherical slot is opened on the bottom surface of the positioning plate 20, and the positioning plate 20 is installed on the side wall of the vertical plate 9.

[0046] The principles and beneficial effects of the above scheme are:

[0047] When the distance between the spline tube 10 and the screw rod 12 becomes larger, in order to prevent the pressure in the spline tube 10 from being too low so that the screw rod 12 cannot be separated from it, the exhaust pipe 12 is connected to the side wall of the spline tube 10 to make the spline tube 10 and the external ambient air pressure the same. When the spline tube 10 is moved into place, the spherical plug 24 is plugged into the spherical slot on the bottom of the positioning plate 20, the spring 25 is compressed, and the sealing disk 23 and the pressure relief column 22 move downward synchronously, so that the exhaust groove is closed to end the conduction between the spline tube 10 and the external environment, and the spline tube 10 is sealed.

[0048] Example 6: Reference Figure 1-Figure 13 The side wall of the screw 12 is connected with a steering tube 26, which is connected to the circular hole 18. A steering column 27 is rotatably connected in the steering tube 26. The top of the steering column 27 is rotatably sealed with the circular hole 18. A discharge hole 28 is penetrated through the steering column 27. The discharge hole 28 and the circular hole 18 are staggered. A spline shaft 29 is provided at the bottom end of the steering column 27. The spline shaft 29 is arranged toward the spline slot 30. The spline slot 30 is opened at the top of the guide column 31. The bottom end of the guide column 31 is connected to the top end of the pull rod 32. The pull rod 32 is slidably connected to the second mounting hole on the side wall of the beam 4. The bottom end of the guide column 31 is connected to the inner wall of the beam 4 through the second spring 33. The storage tube 13 is filled with oxygen.

[0049] The principles and beneficial effects of the above scheme are:

[0050] During the rotation of the screw 12, the steering tube 26 drives the steering column 27 to rotate synchronously. When the lifting plate 8 rises to its position, the spline shaft 29 at the bottom of the steering column 27 is set towards the pull rod 32, and the pull rod 32 is moved upward. The spring 23 rises synchronously, and the spline slot 30 on the guide column 31 is plugged into the spline shaft 29. At this time, the rotating pull rod 32 drives the steering column 27 to rotate, and the discharge hole 28 on the steering column 27 is connected to the circular hole 18. Under the pressure relief effect of the oxygen in the storage tube 13, the thermite powder therein is driven into the spline tube 10 and contacts with the electrode column 19. Since the other end of the electrode column 19 is placed outside the mounting seat 2, the other end of the electrode column 19 can be connected to an electrode, and the rotating shaft 217 is connected to another electrode. The electrode column 19 generates a tip discharge, so the thermite can The reaction is carried out and the spline shaft 10 and the screw 12 are welded. Under the action of oxygen, a combustion-supporting effect can be provided for the welding process, and the oxidation effect of the structure in the device is increased to increase the welding firmness. At the same time, oxygen can also maintain the heat of welding during the welding process, avoid the rapid cooling of the mechanism or thermite and end the welding early, and further increase the welding effect of the mechanism. Under the action of the above scheme, the firmness of the device after connection is greatly enhanced, that is, the mechanism in the device is fully utilized and the difficulty of device welding can be reduced; the sealing degree of the storage tube 13 is increased before the discharge hole 28 is connected with the circular hole 18. When the circular hole 18 is connected with the discharge hole 28, the release of oxygen facilitates the discharge of thermite powder into the spline tube 10. At the same time, the setting of the circular hole 18 reduces the difficulty of thermite powder and oxygen injection.

[0051] Example 7: Reference Figure 1-Figure 13 , also includes: a supporting mechanism, the side wall of the beam 4 is connected to the end of the supporting mechanism, the mounting seat 2 is connected to the other end of the supporting mechanism, and multiple supporting mechanisms are arranged around the beam 4, and the supporting mechanism includes: a positioning plate 34 and a supporting rod 35, the two ends of the support rod 35 are respectively connected to a positioning plate 34, one positioning plate 34 is connected to the side wall of the beam 4, and the other positioning plate 34 is connected to the mounting seat 2.

[0052] The principles and beneficial effects of the above scheme are:

[0053] Connecting multiple supporting mechanisms between the crossbeam 4 and the mounting seat 2 can increase the load-bearing and anti-vibration capabilities of the device after installation. The arrangement of the positioning plate 34 and the supporting rod 35 greatly improves the overall strength of the device.

[0054] Example 8: Reference Figure 1-Figure 13The positioning plate 34 includes: a plate body 36, a positioning column 37, a slider 38 and a rotating shaft 39. The two plate bodies 36 are respectively connected to the mounting seat 2 and the crossbeam 4. A plurality of positioning columns 37 are arranged in a linear array on each plate body 36. Both sides of the plate body 36 are respectively slidably connected to a slider 38, and a rotating shaft 39 is rotatably connected between the two sliders 38.

[0055] The principles and beneficial effects of the above scheme are:

[0056] The plate body 36 provides a sliding position for the slider 38, and the two sliders 38 are rotatably connected via a rotating shaft 39 to increase the integrity of the mechanism.

[0057] Example 9: Reference Figure 1-Figure 13 The support rod 35 includes: a positioning wheel 40, a positioning hole 41, a bevel gear three 42, a bevel gear four 43, a driving mechanism 44 and a steering tube 45. The positioning wheel 40 and the bevel gear three 42 are installed on the rotating shaft three 39. The side wall of the positioning wheel 40 is provided with a plurality of positioning holes 41. The positioning holes 41 are plug-fitted with the positioning columns 37. The bevel gear three 42 is meshedly connected with the bevel gear four 43. The bevel gear four 43 is installed at the end of the driving mechanism 44. The driving mechanism 44 is rotatably connected to the steering tube 45. The side of the steering tube 45 is rotatably connected to the rotating shaft three 39.

[0058] The principles and beneficial effects of the above scheme are:

[0059] The driving mechanism 44 can drive the bevel gear four 43 to rotate, and the bevel gear four 43 drives the bevel gear three 42 meshing with it to rotate, thereby rotating the rotating shaft three 39 and the positioning wheel 40. The steering tube 45 guides the rotation of the driving mechanism 44. The steering tube 45 and the rotating shaft three 39 can rotate to adjust the angle between the driving mechanism 44 and the plate body 36. The positioning hole 41 and the positioning column 37 can be plugged in and cooperated to guide the positioning wheel 40.

[0060] Example 10: Reference Figure 1-Figure 13 The driving mechanism 44 includes: a rotating shaft 46, a second jack, a plug rod 47, a waist-shaped hole 48, and a locking mechanism 49. The bevel gear 43 is connected to the end of the rotating shaft 46, and the rotating shaft 46 is rotatably connected to the steering tube 45. A plug hole 2 is opened in the middle of the bevel gear 43, and the plug hole 2 is connected to the inner wall of the waist-shaped hole 48. The waist-shaped hole 48 is opened on the side wall of the rotating shaft 46. The plug rod 47 is slidably connected in the plug hole 2. One end of the plug rod 47 is connected to the locking mechanism 49, and the locking mechanism 49 is connected to the rotating shaft 46. The other end of the plug rod 47 is plugged into a positioning hole 41, and the plug rod 47 is set at an angle to the positioning column 37.

[0061] The principles and beneficial effects of the above scheme are:

[0062] When the positioning wheel 40 needs to be rotated, the insertion rod 47 is pulled upward through the locking mechanism 49, and the insertion rod 47 ends the plug-in cooperation with the positioning hole 41, and the gear 43 of the rotating shaft 46 is rotated synchronously, and the gear 43 drives the bevel gear 3 42 meshing with it to rotate, thereby rotating the rotating shaft 39 and the positioning wheel 40, and finally one end of the support rod 35 is moved on a positioning plate 34 through the guidance of the slider 38, and at the same time, after the other locking mechanism 49 is unlocked, the other end of the support rod 35 slides with the other positioning plate 34, and finally the support rod 35 is adjusted. The angle between the beam 4 and the mounting seat 2 is then changed, and the two locking mechanisms 49 respectively drive an insertion rod 47 to engage with the positioning hole 41. At this time, one positioning hole 41 on the positioning wheel 40 is engaged with the insertion rod 47, and the other positioning hole 41 is engaged with the positioning column 37. Due to the angle between the two, the positioning 40 is locked, and finally the support rod 35 is locked. After the angle is changed, the end of the support rod 35 re-fixes the beam 4 and the mounting seat 2. The support rod 35 distributes the force on the beam 4 and the mounting seat 2 according to the actual situation, thereby improving the practicality of the device itself.

[0063] Example 11: Reference Figure 1-Figure 13 The locking mechanism 49 includes: a double-threaded rod 50, a second screw tube 51, an unlocking rod 52, a third spring 53, a fourth spring 54, an unlocking plate 55 and an unlocking column 56. The other end of the rotating shaft 46 is connected with the second screw tube 51, and the second screw tube 51 is threadedly connected to the end of the double-threaded rod 50. The other end of the insertion rod 47 is slidably connected to the unlocking rod 52. The mounting ring on the unlocking rod 52 is connected to the end of the spring third 53. The other end of the spring third 53 is connected to the other end of the insertion rod 47. The end surface of the other end of the insertion rod 47 is connected to the inner wall of the waist-shaped hole 48 through the spring fourth 54. The bottom end of the unlocking rod 52 is slidably connected to the unlocking plate 55. The other end of the unlocking plate 55 is connected to the bottom end of the unlocking column 56. The unlocking column 56 is slidably connected to the unlocking hole on the side wall of the second screw tube 51. The other end of the unlocking column 56 is plugged into the longitudinal groove on the side wall of the double-threaded rod 50. A plurality of longitudinal grooves are arranged in a circular array on the side wall of the double-threaded rod 50.

[0064] The principles and beneficial effects of the above scheme are:

[0065] When the insertion rod 47 needs to be moved out of the positioning hole 41, the unlocking rod 52 is pulled upward, the spring four 54 is compressed, and after the unlocking rod 52 is released, the insertion rod 47 is again plugged into the positioning hole under the elastic force of the spring four 54. The cooperation between the mechanism and the waist-shaped hole 48 reduces the difficulty of moving the insertion rod 47. Under the premise that the two locking mechanisms 49 work at the same time, since the double-threaded rod 50 is set in the mechanism, the unlocking rod 52 can also be pressed, the spring three 53 is compressed, the unlocking plate 55 and the unlocking column 56 move downward, and after the unlocking column 56 is separated from the longitudinal groove, the double-threaded rod 50 can be engaged with the screw pipe two 51 rotates relative to each other, so the length of the support rod 35 can be extended or shortened, and the position of the connection between its end and the crossbeam 4 or the mounting seat 2 can be further controlled, thereby further increasing the practicability of the mechanism. After the rotation of the double-threaded rod 50 is completed, the unlocking rod 52 is released, and the spring three 53 is reset to drive the unlocking plate 55 and the unlocking column 56 to move upward, and the unlocking column 56 is re-inserted into the longitudinal groove, thereby fixing the double-threaded rod 50 and increasing the stability of the device after adjustment; since the unlocking rod 52 is slidably connected to the unlocking plate 55, there will be no interference between the components when the unlocking plug 47 is unlocked.

They can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and the illustrations shown and described herein.
