Description

Technical Field

[0001] The utility model relates to the technical field of steel structures, and particularly relates to an H-shaped steel structure connection joint. Background Technique

[0002] A steel structure is a structure composed of steel materials and is one of the main building structure types. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of sections and steel plates, and rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are adopted. The components or parts are usually connected by welds, bolts or rivets. Because of its light self-weight and simple construction, it is widely used in large factories, stadiums, super high-rise buildings, bridges and other fields. Steel structures are prone to rust, and general steel structures need to be derusted, galvanized or painted, and need to be maintained regularly.

[0003] During the long-term use after the completion of the steel structure construction, the steel structure itself will not be damaged without bearing large external forces, but during the long-term use, the main reasons for bolt loosening include loosening caused by vibration and loosening caused by material deformation. Loosening caused by vibration is caused by reasons such as impact, vibration or cyclic thermal load, resulting in the rotation and loosening of the bolt. Even a slight rotation is sufficient to cause the bolt connection to lose all the pre-tightening force. Loosening caused by material deformation is caused by three mechanisms, including sinking, etc. These mechanisms cause the loss of pre-tightening force, and then cause the joint to open, and finally cause the bolt to loosen. For this reason, we propose an H-shaped steel structure connection joint. Content of the Utility Model

[0004] In view of the deficiencies of the prior art, the utility model provides an H-shaped steel structure connection joint, which solves the problems raised in the above background technique.

[0005] To achieve the above purposes, the utility model is realized through the following technical solutions: an H-shaped steel structure connection joint, including a support column, a support block is fixedly installed on the outer side of the support column, a positioning block is fixedly installed on the outer side of the support column, an H-shaped steel is movably sleeved inside the support block and the positioning block, a sealing sleeve is fixedly installed on the outer side of the positioning block, a connecting bolt is movably sleeved outside the positioning block, a sealing glue is movably sleeved between the positioning block and the sealing sleeve, and a connecting block is sleeved inside the support block and the H-shaped steel.

[0006] Optionally, the outer sides of the H-shaped steel are respectively in contact with the outer sides of the support block and the positioning block, and a rectangular frame for fitting the connecting block is opened inside the H-shaped steel.

[0007] Optionally, the length value of the connecting block is the same as the distance value between the outer sides of the two support blocks, and the connecting block and the support block are connected by full welding.

[0008] Optionally, the bottom end of the connecting bolt extends into the H-shaped steel and the support block, and the sealant covers the outside of the connecting bolt.

[0009] Optionally, the top surface of the plugging sleeve and the top surface of the positioning block are on the same horizontal plane, and the width value of the positioning block is the same as the width value of the support block.

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0019] Please refer to Figures 1 to 4, the present utility model provides a technical solution: an H-shaped steel structure connection joint, including a support column 1, a support block 3 is fixedly installed on the outer side of the support column 1, a positioning block 5 is fixedly installed on the outer side of the support column 1, an H-shaped steel 2 is movably sleeved inside the support block 3 and the positioning block 5, the bottom end of the connecting bolt 8 extends into the inside of the H-shaped steel 2 and the support block 3, sealant 7 covers the outside of the connecting bolt 8. The cooperation of the support block 3 and the positioning block 5 can assist in supporting the H-shaped steel 2, thereby realizing the stable connection of the H-shaped steel 2. At the same time, the setting of the connecting bolt 8 can play an auxiliary fixing role, and the setting of the sealant 7 can block the connecting bolt 8 to prevent the connecting bolt 8 from rusting after contacting the air, which affects the convenience of subsequent maintenance. At the same time, rust will also cause loosening of the connection, which can effectively avoid potential safety hazards. The outer side of the H-shaped steel 2 is respectively in contact with the outer sides of the support block 3 and the positioning block 5. A rectangular frame for fitting the connecting block 4 is opened inside the H-shaped steel 2. The setting of the connecting block 4 plays a role in stably connecting and supporting the H-shaped steel 2 and the support block 3, which can ensure the stability of the H-shaped steel 2 and prevent the H-shaped steel 2 from loosening during use. The cooperation of the connecting block 4 and the support block 3 can stably connect the H-shaped steel 2. A sealing sleeve 6 is fixedly installed on the outer side of the positioning block 5. The top surface of the sealing sleeve 6 and the top surface of the positioning block 5 are on the same horizontal plane. The width value of the positioning block 5 is the same as the width value of the support block 3. The setting of the sealing sleeve 6 plays a role in cooperating with the sealant 7 to seal the connecting bolt 8. The positioning block 5 and the sealing sleeve 6 can cooperate to form a frame to limit the sealant 7 and prevent the sealant 7 from overflowing outward, which affects the stability of the connection. The connecting bolt 8 is movably sleeved outside the positioning block 5, and the sealant 7 is movably sleeved between the positioning block 5 and the sealing sleeve 6. The connecting block 4 is sleeved inside the support block 3 and the H-shaped steel 2. Insert the connecting block 4 inward from the outside of the support block 3, so that the connecting block 4 passes through the H-shaped steel 2 and is placed into the inner cavity of the opposite support block 3. Fix the two support blocks 3 and the H-shaped steel 2 through the connecting block 4. Then, pour the sealant 7 into the inside of the positioning block 5 and the sealing sleeve 6 to form a seal on the outside of the connecting bolt 8 through the sealant 7. Then, fully weld and grind the support block 3 and the connecting block 4. The length value of the connecting block 4 is the same as the spacing value between the outer sides of the two support blocks 3. The connecting block 4 and the support block 3 are connected by full welding.

[0020] In summary, for the installation of this H-shaped steel structure connection joint, place the H-shaped steel 2 from the outside of the two support blocks 3 towards the space between the two support blocks 3, so that the H-shaped steel 2 fits against the support column 1, the two support blocks 3 and the two positioning blocks 5. Rotate the connecting bolt 8 downward from above the positioning block 5, so that the connecting bolt 8 is sent inward into the interior of the support block 3. Fix the positioning block 5, the support block 3 and the H-shaped steel 2 with the connecting bolt 8. Then insert the connecting block 4 inward from the outside of the support block 3, so that the connecting block 4 passes through the H-shaped steel 2 and is placed into the inner cavity of the opposite support block 3. Fix the two support blocks 3 and the H-shaped steel 2 with the connecting block 4. Then pour the sealant 7 into the interior of the positioning block 5 and the plugging sleeve 6 to form a seal for the outside of the connecting bolt 8 with the sealant 7. Then fully weld and grind the support block 3 and the connecting block 4 flat, and that's it.
