[0031] Example

[0032] See also Figures 1 to 5 A two-way hinged connection structure includes a hoop 1 and a column 2. The hoop 1 can be movably mounted on the column 2. The hoop 1 is provided with a first pin 11 and a second pin 12. The first pin 11 and the second pin 12 are staggered. The column 2 can rotate along a first direction of the hoop 1 through the first pin 11, and the column 2 can rotate along a second direction of the hoop 1 through the second pin 12.

[0033] In this embodiment, the hoop 1 is a hollow square tube structure made of steel material, the column 2 is a high-precision steel column, and the hoop 1 can be movably sleeved on the column 2. For the convenience of explanation, the column 2 is set in the vertical direction, that is, the opening of the hoop 1 is set in the vertical direction, the length direction and width direction of the hoop 1 are consistent with the horizontal plane direction, the first pin 11 is set in the width direction of the hoop 1, and the second pin 12 is set in the length direction of the hoop 1. In order to avoid interference between the first pin 11 and the second pin 12, the first pin 11 and the second pin 12 are staggered in the vertical direction. The column 2 can be rotated in the first direction through the first pin 11 or in the second direction through the second pin 12. At this time, the hoop 1 is fixed to the main structure 4, and the column 2 is connected to another steel frame structure, so that a two-way force steel frame connection can be realized, which is very convenient. Among them, the first pin 11 and the second pin 12 are both made of 40Cr steel material, and the surface of the pins is hardened and galvanized for corrosion protection.

[0034] Before installing the clamp 1 to the main structure 4, in order to avoid shaking between the clamp 1 and the column 2, the clamp 1 is provided with a clamp positioning screw hole, and the column 2 is correspondingly provided with a column positioning screw hole. The positioning bolts 13 are passed through the clamp positioning screw holes and the column positioning screw holes in sequence to fix the two. After the clamp 1 is fixed to the main structure 4, the positioning bolts 13 are removed to restore the movement between the clamp 1 and the column 2.

[0035] In one embodiment, the structures of the first pin shaft 11 and the second pin shaft 12 are improved to ensure the stability and reliability of the bidirectional hinge connection structure. Specifically, the diameter of the first pin shaft 11 is d1, the diameter of the second pin shaft 12 is d2, and the distance between the first pin shaft 11 and the second pin shaft 12 is D, where D>3*d1 or D>3*d2.

[0036] In this embodiment, the diameter of the first pin shaft 11 is d1, and the diameter of the second pin shaft 12 is d2, wherein d1>d2, so that the clamp 1 can bear the weight of the column through the first pin shaft 11 while ensuring the stability and reliability of the column 2 rotating along the first direction.

[0037] In order to ensure the range of motion between the clamp 1 and the column 2, the distance between the first pin 11 and the second pin 12 is greater than three times the diameter of the first pin 11, or greater than three times the diameter of the second pin 12. When the diameter of the first pin 11 is greater than the diameter of the second pin 12, the distance between the first pin 11 and the second pin 12 is greater than three times the diameter of the second pin 12.

[0038] In one embodiment, the structure of the column 2 is improved to facilitate adjustment of the position between the column 2 and the clamp 1. Specifically, the column 2 is provided with a first column pin hole 21 corresponding to the first pin 11, and the column 2 is provided with a second column pin hole 22 corresponding to the second pin 12, and both the first column pin hole 21 and the second column pin hole 22 are oval holes.

[0039] In this embodiment, the oval holes are all arranged along the length direction of the column 2 , so as to facilitate the adjustment of the position between the column 2 and the clamp 1 through the first pin shaft 11 and the second pin shaft 12 .

[0040] In one embodiment, the structure of the clamp 1 is improved to ensure the reliability of the connection between the clamp 1 and the column 2. Specifically, the first pin hole 21 of the column and the second pin hole 22 of the column are filled with lubricating grease.

[0041] In this embodiment, by filling lubricating grease into the first pin shaft hole 21 of the column and the second pin shaft hole 22 of the column, the friction between the first pin shaft 11 and the second pin shaft 12 and the column 2 can be reduced. At the same time, the lubricating grease can isolate the hole wall of the first pin shaft hole 21 of the column and the hole wall of the second pin shaft hole 22 of the column from the air, thereby preventing moisture in the air from corroding the column 2, thereby effectively extending the service life of the two-way hinged connection structure.

[0042] In one embodiment, the structures of the hoop 1 and the column 2 are improved to ensure that the connection structure can absorb the slight bending deformation of the column caused by the double supports. Specifically, the hoop 1 and the column 2 are clearance-matched.

[0043] In this embodiment, by allowing the gap between the clamp 1 and the column 2 to be matched, a certain amount of movement can be provided between the clamp 1 and the column 2, so that the slight bending deformation of the column 2 caused by the double support can be absorbed. Preferably, the spacing between the clamp 1 and the column 2 is at least 5 mm. By allowing a gap of at least 5 mm between the clamp 1 and the column 2, the amount of movement between the clamp 1 and the column 2 can be guaranteed, and the stability and reliability of the connection between the clamp 1 and the column 2 can be guaranteed.

[0044] In one embodiment, the structures of the clamp 1 and the column 2 are improved to ensure the reliability of the connection between the clamp 1 and the column 2. Specifically, lubricating grease is filled between the clamp 1 and the column 2.

[0045] In this embodiment, by filling lubricating butter between the clamp 1 and the column 2, the inner wall of the clamp 1 and the outer wall of the column 2 can be isolated from the air, thereby preventing harmful substances in the air from corroding the clamp 1 and the column 2, and effectively extending the service life of the two-way hinged connection structure. At the same time, the lubricating butter can also provide a certain buffering effect between the clamp 1 and the column 2.

[0046] In one embodiment, the structure of the clamp 1 is improved to facilitate the installation of the clamp 1 on the main structure 4. Specifically, a support 3 is provided on each side of the clamp 1.

[0047] In this embodiment, a support 3 is provided on each side of the clamp 1 along the width direction. In order to ensure the reliability and stability of the connection between the support 3 and the clamp 1, the support 3 and the clamp 1 are fixed by welding. The support 3 specifically includes a first support plate and a second support plate, the first support plate and the second support plate are arranged at 90 degrees, and the side surface of the support is "L" shaped. Preferably, the first support plate and the second support plate are an integral structure, and the support of the integral structure can realize a reliable connection between the clamp 1 and the main structure 4.

[0048] The support 3 is provided with a support shaft hole corresponding to the second pin shaft 12, and the support shaft hole is filled with lubricating grease, which can lubricate and isolate the hole wall of the support shaft hole from the air, thereby preventing harmful substances in the air from corroding the support shaft hole and the second pin shaft 12, and effectively extending the service life of the clamp 1. Preferably, the support shaft hole can also be sealed by a butyl tape 32 to prevent the leakage of lubricating grease and increase the isolation effect between the hole wall of the support shaft hole and the air.

[0049] In one embodiment, the structure of the support 3 is improved to ensure the structural strength of the support 3. Specifically, the support 3 is provided with ribs 31.

[0050] In this embodiment, the structural strength of the support 3 is strengthened by adding two ribs 31. The two ribs 31 are parallel to each other. One side of the two ribs 31 is welded to the first support plate, and the other side of the two ribs 31 is welded to the second support plate, thereby effectively increasing the overall structural strength of the support 3 and reducing the risk of deformation of the support 3 due to force.

[0051] From the above description, it can be seen that the beneficial effects of the utility model are: providing a two-way hinged connection structure, which includes a clamp and a column, the clamp can be movably mounted on the column, and can absorb the slight bending deformation of the column caused by the action of the double supports, the clamp is provided with a first pin and a second pin, the first pin and the second pin are staggered, the column can be rotated along the first direction of the clamp through the first pin, and the column can be rotated along the second direction of the clamp through the second pin. The connection structure has a reasonable structure, is easy to install, has good safety and reliability, and can be suitable for large-span two-way stressed steel frame connections.

[0052] It is easy for those skilled in the art to understand that the above-mentioned implementation modes can be freely combined and superimposed without conflict.

[0053] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
