DETAILED DESCRIPTION

[0029] 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 technical personnel in this field without creative work are within the scope of protection of the present invention.

[0031] A connector for an earthquake-resistant steel structure, comprising a connector body 4, a mounting groove 5 is vertically provided in the middle of the connector body 4, a support beam 1 is movably inserted in the mounting groove 5, transverse grooves 6 are provided around the connector body 4, a transverse beam 3 is movably inserted in the transverse groove 6, and a locking mechanism 7 is movably connected between the end of the transverse beam 3 and the inner wall of the transverse groove 6. It should be noted that: the support beam 1 can be set as a rectangular steel structure or a tubular steel structure, and the support beam 1 and the transverse beam 3 are both made of earthquake-resistant steel materials. The steel structures in the prior art are all made of earthquake-resistant steel materials, which will not be described in detail here; the end of the transverse beam 3 is provided with an oblique chamfer, and the oblique chamfer is set to facilitate the insertion of the end of the transverse beam 3 into the transverse groove 6.

[0032] An adjustment mechanism 8 that cooperates with the locking mechanism 7 is movably connected between the surface of the support beam 1 and the top of the connector body 4. Four diagonal braces 9 are fixedly connected to the lower part of the connector body 4 at equal intervals along the circumference. The four diagonal braces 9 correspond to the four cross beams 3 one by one, and the bottom of the cross beam 3 overlaps the top of the corresponding diagonal brace 9. It should be noted that: the lower part of the diagonal brace 9 is fixedly connected with an anti-slip bolt, one end of the diagonal brace 9 is fixedly connected to the side wall of the support beam 1 through the anti-slip bolt, the top of the diagonal brace 9 is provided with a groove, the bottom of the cross beam 3 overlaps the inside of the groove, and the inner wall of the groove is fixedly connected with a rubber pad to improve the seismic effect.

[0033] In this embodiment, Figures 1 to 6 As shown, the locking mechanism 7 includes a semicircular groove 701, and there are two semicircular grooves 701, one of which is opened on the inner top surface of the transverse groove 6, and the other semicircular groove 701 is opened on the top of the cross beam 3, and the two semicircular grooves 701 are arranged opposite to each other. It should be noted that: when the cross beam 3 is fully inserted into the corresponding transverse groove 6, the plane ends of the two semicircular grooves 701 overlap to form a spherical cavity.

[0034] The semicircular groove 701 is internally rotatably connected with a hemispherical locking block 702, and the planar ends of the two hemispherical locking blocks 702 are fitted together. The inner wall of the connecting piece body 4 and the inner wall of the beam 3 are both provided with fan-shaped grooves 703, and the two fan-shaped grooves 703 correspond one to one to the two semicircular grooves 701. One end of the fan-shaped groove 703 extends to the interior of the adjacent semicircular groove 701. The upper fan-shaped groove 703 is internally movably connected with a main pull plate 704 that cooperates with the adjustment mechanism 8, and one end of the main pull plate 704 is fixedly connected to the side wall of the adjacent hemispherical locking block 702. The lower fan-shaped groove 703 is internally movably connected with a slave pull plate 705, and one end of the slave pull plate 705 is fixedly connected to the side wall of the adjacent hemispherical locking block 702. It should be noted that the top of the fan-shaped groove 703 inside the connector body 4 extends to the outside of the connector body 4 , and the top of the main pull plate 704 extends to the top of the connector body 4 and is fixedly connected with a ball head that matches the adjustment mechanism 8 .

[0035] A spring telescopic rod 706 is fixedly connected to one side of the inner wall of the fan-shaped groove 703, and the movable end of the spring telescopic rod 706 overlaps with the other side of the inner wall of the fan-shaped groove 703. A guide pin 707 is fixedly connected to the surface of the spring telescopic rod 706. Guide grooves 708 are provided on the surfaces of the main pull plate 704 and the slave pull plate 705, and two guide pins 707 are respectively slidably connected to the inside of the two guide grooves 708. It should be noted that: the guide pin 707 is fixedly connected to the movable end position of the spring telescopic rod 706. When the main pull plate 704 is pulled to swing inside the fan-shaped groove 703, the guide groove 708 on the main pull plate 704 cooperates with the guide pin 707 on the surface of the spring telescopic rod 706 to slide. At this time, the spring telescopic rod 706 contracts, and the main pull plate 704 pulls the hemispherical locking block 702 to rotate inside the corresponding semicircular groove 701. When the main pull plate 704 swings to the extreme position, the hemispherical locking block 702 is in an overlapping state with the semicircular groove 701; when the main pull plate 704 is not pressed or pulled, the semicircular locking block is in an inclined state inside the semicircular groove 701.

[0036] In this embodiment, Figures 1 to 6 As shown, three steel balls are fixedly connected to the surface of the hemispherical locking block 702 at equal intervals, and the surface of the steel balls overlaps the inner wall of the semicircular groove 701. It should be noted that: the provision of the steel balls reduces the friction resistance of the hemispherical locking block 702 during the rotation process inside the semicircular groove 701; and the contact between the steel balls and the inner wall of the semicircular groove 701 avoids the hemispherical locking block 702 and the inner wall of the semicircular groove 701 from having too large a gap, thereby causing the hemispherical locking block 702 to swing inside the semicircular groove 701, and avoiding affecting the stability of the two hemispherical locking blocks 702 after they are locked together.

[0037] In this embodiment, Figures 1 to 6 As shown, the adjustment mechanism 8 includes an external thread sleeve 801, which is fixedly connected to the upper part of the support beam 1, and a conical adjustment sleeve 802 is threadedly connected to the surface of the external thread sleeve 801, and the inner bottom surface of the conical adjustment sleeve 802 is provided with a chamfer 803 that matches the locking mechanism 7. It should be noted that: when the conical adjustment sleeve 802 is rotated and moved downward on the surface of the external thread sleeve 801, the chamfer 803 of the inner bottom surface of the conical adjustment sleeve 802 overlaps the side wall position of the upper part of the main pull plate 704, and the main pull plate 704 is limited.

[0038] Pressure rods 804 are vertically and movably inserted around the top of the conical adjustment sleeve 802 , and a pressing frame 805 is fixedly connected between the tops of the four pressure rods 804 . The pressing frame 805 is movably sleeved on the upper part of the support beam 1 .

[0039] The surface of the conical adjustment sleeve 802 is movably sleeved with an adjustment frame 806, which is arranged at the lower position of the conical adjustment sleeve 802, the bottom of the pressure rod 804 overlaps the top of the adjustment frame 806, and the four sides of the adjustment frame 806 are symmetrically hinged with connecting rods 807, and a compression spring 808 is fixedly connected between the bottom of the adjustment frame 806 and the top of the connector body 4. It should be noted that the compression spring 808 is movably sleeved on the surface of the support beam 1, and moves downward with the pressure rod 804 by pressing the pressing frame 805, so that the pressure rod 804 presses the adjustment frame 806 to move downward on the surface of the support beam 1, and at this time, the lower ends of the eight connecting rods 807 at the lower part of the adjustment frame 806 are in an open state and move around.

[0040] The top of the connector body 4 is symmetrically slidably connected with slide bars 809 on all sides, and the eight slide bars 809 correspond to the eight connecting rods 807 one by one. The lower part of the connecting rod 807 is hinged to the end of the adjacent slide bar 809, and a push rod 810 is fixedly connected between the side walls of two adjacent slide bars 809, and the surface of the push rod 810 overlaps the surface of the locking mechanism 7. It should be noted that when the lower parts of the eight connecting rods 807 are in an open state and move around, the push rod 810 between two adjacent connecting rods 807 will push the upper pull plate to swing inside the corresponding fan-shaped groove 703, so that the four main pull plates 704 can move synchronously, and the installation of the four beams 3 is unlocked at the same time.

[0041] In this embodiment, Figures 1 to 6 As shown, the upper part of the pressing rod 804 is movably sleeved with a pressing spring, the top of the pressing spring is overlapped with the bottom of the pressing frame 805, and the bottom of the pressing spring is overlapped with the top of the conical adjustment sleeve 802. It should be noted that the pressing of the pressing spring on the top of the conical adjustment sleeve 802 ensures the stability of the conical adjustment sleeve 802 pressing the main pull plate 704 after it moves downward.

[0042] In this embodiment, Figures 1 to 6 As shown, the adjustment frame 806 is set as a T-shaped frame, and a support ball is fixedly connected to the bottom of the pressure rod 804, and the pressure rod 804 is overlapped on the top of the adjustment frame 806 through the support ball. It should be noted that: through the setting of the support ball, when the conical adjustment sleeve 802 rotates with the pressure rod 804, the friction resistance between the bottom of the pressure rod 804 and the top of the adjustment frame 806 is reduced.

[0043] In this embodiment, Figures 1 to 6 As shown, eight sliders are fixedly connected to the top of the connector body 4, and the eight sliders correspond to eight slide bars 809 one by one. One end of the slide bar 809 away from the connecting rod 807 is slidably connected to the inside of the slider.

[0044] The use method and advantages of the present invention: The seismic-resistant steel structure connector and the steel structure have the following working process:

[0045] like Figures 1 to 6As shown, when assembling the earthquake-resistant steel structure, after assembling the support beam 1 and the connector body 4 by means of the diagonal brace 9, the end of the cross beam 3 is inserted into the transverse groove 6 provided on the side wall of the connector body 4. When the hemispherical locking block 702 at the end position of the cross beam 3 contacts the end position of the transverse groove 6, the hemispherical locking block 702 on the cross beam 3 slides into the corresponding semicircular groove 701. At the same time, when the hemispherical locking block 702 inside the transverse groove 6 contacts the end of the cross beam 3, the hemispherical locking block 702 inside the transverse groove 6 slides into the corresponding semicircular groove 701. As the cross beam 3 is gradually inserted into the transverse groove 6, the plane ends of the two hemispherical locking blocks 702 gradually become horizontal and are located inside the corresponding semicircular groove 701. When the cross beam 3 is in the transverse groove 6, After the parts move to the extreme position, the plane ends of the two semicircular grooves 701 overlap, and under the elastic recovery effect of the spring telescopic rod 706, the guide pins 707 at the movable ends of the two spring telescopic rods 706 cooperate with the guide grooves 708 on the corresponding main pull plate 704 and the slave pull plate 705 to slide, and the main pull plate 704 rotates counterclockwise inside the semicircular groove 701 with the upper hemispherical locking block 702, and the slave pull plate 705 rotates counterclockwise inside the semicircular groove 701 with the lower semicircular locking block, so that the two hemispherical locking blocks 702 that are attached together are locked in an inclined state inside the two semicircular grooves 701 after overlap. In this process, it is only necessary to insert the crossbeam 3 into the cross groove 6 on the side wall of the connector body 4 to the extreme position to complete the automatic locking;

[0046] When the four cross beams 3 are inserted into the four transverse grooves 6 on the connector body 4 and locked automatically, the conical adjustment sleeve 802 on the upper part of the support beam 1 is rotated to move the conical adjustment sleeve 802 downward and press against the side wall position of the upper part of the four main pull plates 704 through the chamfer 803, so as to limit the movement of the main pull plates 704, and further limit the installation of the four cross beams 3 synchronously;

[0047] When a single crossbeam 3 needs to be replaced or disassembled, the conical adjustment sleeve 802 on the surface of the external threaded sleeve 801 is rotated to rise, and then the main pull plate 704 at the top position of the crossbeam 3 to be replaced is pulled, so that the main pull plate 704 with the fixedly connected hemispherical locking block 702 rotates inside the two semicircular grooves 701, and the other hemispherical locking block 702 also rotates. After the main pull plate 704 is pulled to the extreme position, the planar ends of the two hemispherical locking blocks 702 are in a horizontal state. At this time, the connection between the cross groove 6 and the crossbeam 3 is unlocked, and the crossbeam 3 can be pulled out from the cross groove 6.

[0048] The above shows and describes the basic principles, main features and advantages of the present invention. Technical personnel in this industry should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not used to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected. The scope of protection of the present invention is defined by the attached claims and their equivalents.
