[0001] This invention relates to the field of steel structure technology, specifically to a steel structure connection component and its usage method. Background Technology

[0002] Steel structures are structural forms made of steel as the main material and connected by welding, bolting or riveting. They have advantages such as high strength, light weight, fast construction speed and high degree of industrialization, and are widely used in many fields such as construction, bridges, towers, and machinery manufacturing. Steel structure connection components are various components and devices used to connect the various parts of a steel structure to form a complete structural system. These connection components play a vital role in steel structures. They not only ensure the integrity and stability of the structure, but also affect the load-bearing capacity, construction efficiency and service life of the structure. Existing steel structure connection components are classified into welded connection components, bolted connection components and riveted connection components, etc., according to their different connection methods.

[0003] However, the bolted connection components have low fixing strength, and the bolts and nuts on the bolted connection components may loosen during long-term use, thus affecting the stability of the overall steel structure and posing a high risk. Therefore, they do not meet the existing requirements. To address this, we propose a steel structure connection component and its usage method. Summary of the Invention

[0010] Preferably, a ring of second fixing bolts is installed on the outer surface of the top end of the first loop-shaped lifting frame and the outer surface of the bottom end of the second loop-shaped lifting frame from top to bottom, and the loop-shaped lifting frame is fixed to the steel structure column by the second fixing bolts.

[0011] Preferably, each of the four corners on the outer side of the strip-shaped reinforcing head is provided with an I-shaped steel fixing bolt. The I-shaped steel fixing bolt penetrates through the top end of the I-shaped steel and is inserted into the interior of the steel structure column shell. Each I-shaped steel is fixed to the steel structure column by four I-shaped steel fixing bolts.

[0012] Preferably, a bolt locking mechanism is provided on one side of each pair of I-shaped rigid fixing bolts. The bolt locking mechanism includes a bolt locking strip metal shell and a quick installation mechanism. A metal column is installed on both sides of the inside of the bolt locking strip metal shell through roller bearings. The metal column has a hexagonal groove on the face facing the I-shaped rigid fixing bolt, and the shape of the inner wall of the hexagonal groove corresponds to the shape of the hexagonal bolt head of the I-shaped rigid fixing bolt. Both sides of the outer surface of the metal column are provided with a screw groove, and a locking pointed screw is provided inside the screw groove. One side of the two locking pointed screws is provided with an annular rubber plate fixed inside the bolt locking strip metal shell, and the position of the annular rubber plate corresponds to the position of the screw head of the locking pointed screw.

[0013] Preferably, the quick installation mechanism includes a square fixing metal head, the inside of which is provided with a spring groove, the inside of which contains a spring, and a rectangular fixing block is connected to both the upper and lower end faces of the spring, and one side of the outer surface of the rectangular fixing block is a third inclined surface. The square fixing metal head has a square mounting groove on one side located on the outer surface of the I-shaped steel and corresponding to its position. The inner wall of the square mounting groove has a square cross-section shape and the shape of the inner wall of the square mounting groove corresponds to the shape of the square fixing metal head. Both sides of the inner wall of the square mounting groove have a rectangular fixing groove whose position corresponds to the two rectangular fixing blocks located on the outer surface of the square fixing metal head.

[0014] Preferably, a method of using a steel structure connection component includes the following steps; Step A: When it is necessary to install an I-beam, align the strip-shaped reinforcement head fixed to the outer surface of the I-beam with the reinforcement through hole located on the outer surface of the steel structure column, and then insert it until the face of the I-beam facing the steel structure column is in contact with the steel structure column. After the two are in contact, use the commonly used bolt fixing method to fix the I-beam to the outer surface of the steel structure column with I-beam fixing bolts. Step B: After the I-beam is fixed to the outer surface of the steel structure column with bolts, the two loop-shaped lifting frames that are respectively movably sleeved on the outer surface of the steel structure column are pushed towards the I-beam. As the loop-shaped lifting frames move towards the I-beam, the L-shaped metal rods fixed on the inner wall of the loop-shaped lifting frames will be inserted into the connecting grooves located on the outer surface of the strip-shaped reinforcement head. When the L-shaped metal rods are inserted into the connecting grooves, a fixed structural network that is synchronously connected inside and outside can be formed between the steel structure column and the I-beam. Step C: After the I-beams are fixed, align the two hexagonal slots on the two metal pillars inside the same bolt-locking strip metal housing with the corresponding hexagonal bolt heads of the two I-beam fixing bolts. Then, use the quick-installation mechanism to fix the bolt-locking strip metal housing onto the outside of the hexagonal bolt heads of the two I-beam fixing bolts. During the installation of the bolt-locking strip metal housing, the hexagonal bolt heads of the two I-beam fixing bolts will also enter the two hexagonal slots on the outer surfaces of the two metal pillars. Inside the scalloped groove, after the bolt-locking strip metal shell is installed, use a screwdriver to rotate the locking pointed screws inside the two screw slots on the outer surface of the metal column until the top end of the locking pointed screw is drilled into the annular rubber plate fixed inside the bolt-locking strip metal shell. Once the locking pointed screw enters the annular rubber plate, the metal column can be fixed. After the metal column is fixed, the I-shaped fixing bolts whose hexagonal bolt heads are inserted into the hexagonal grooves on the outer surface of the metal column will also be fixed.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention uses an internally and externally connected high-strength steel structure connection component to form a fixed structural net that is simultaneously connected internally and externally between the steel structure column and the four I-beams. This fixed structural net in the above technical solution can improve the connection stability between the steel structure column and the I-beams, thereby preventing loosening or deformation between the steel structure column and the I-beams due to external forces. Furthermore, the internal connection structure between the steel structure column and the I-beams can further restrict the displacement of the I-beams, thereby reducing the impact of vibration on the connection parts. 2. This invention uses a bolt locking mechanism to lock and seal the I-beam fixing bolts used to initially fix the steel structure column and the I-beam. This technical solution reduces external corrosion damage to the I-beam fixing bolts, thereby improving the service life of this connection assembly in marine or chemical environments. Simultaneously, locking the I-beam fixing bolts prevents rotation, ensuring a more secure connection between the steel structure column and the I-beam, thus enhancing the overall structural integrity. This enhanced integrity improves the structure's performance under load, reduces stress concentration, and extends the structure's service life. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] Please see Figures 1 to 7 The present invention provides an embodiment of a steel structure connection component, including an internal and external connection type high-strength steel structure connection component 1, including a steel structure column 101 and four I-shaped steel beams 102. Each of the four end corners of the outer surface of the steel structure column 101 is provided with a reinforcing through hole 112, and the positions of the four I-shaped steel beams 102 correspond to the positions of the four reinforcing through holes 112 respectively. A strip-shaped reinforcing head 113 is fixed to the surface of the I-beam 102 facing the corresponding reinforcing through hole 112, and is inserted into the reinforcing through hole 112. A connecting groove 114 is provided on one side of the outer surface of the strip-shaped reinforcing head 113. A U-shaped lifting frame 109 is provided above and below each of the four connecting grooves 114, and is movably fitted onto the outer surface of the steel structure column 101. An L-shaped metal rod 111 is fixed to each of the four corners of the inner wall of the U-shaped lifting frame 109, and the L-shaped metal rod 111 is inserted into the connecting groove 114. An I-beam fixing bolt 103 is provided at each of the four corners of the outer side of the strip-shaped reinforcing head 113, and the I-beam fixing bolt 103 penetrates the I-beam. The top end of the I-beam 102 is inserted into the interior of the outer shell of the steel structure column 101, and each I-beam 102 is fixed to the steel structure column 101 by four I-beam fixing bolts 103. When it is necessary to install the I-beam 102, the strip-shaped reinforcing head 113 fixed to the outer surface of the I-beam 102 is aligned with the reinforcing through hole 112 located on the outer surface of the steel structure column 101, and then inserted until the face of the I-beam 102 facing the steel structure column 101 is in contact with the steel structure column 101. After the two are in contact, the I-beam 102 is fixed to the outer surface of the steel structure column 101 by the commonly used bolt fixing method using the I-beam fixing bolts 103. After the I-beam 102 is fixed to the outer surface of the steel structure column 101 by the I-beam fixing bolts 103, the two U-shaped lifting frames 109, which are respectively movably sleeved on the outer surface of the steel structure column 101, are pushed towards the I-beam 102. As the U-shaped lifting frames 109 move towards the I-beam 102, the L-shaped metal rods 111 fixed on the inner wall of the U-shaped lifting frames 109 will be inserted into the connecting grooves 114 located on the outer surface of the strip-shaped reinforcing head 113. When the L-shaped metal rods 111 are inserted into the connecting grooves 114... Then, a fixed structural net that is synchronously connected internally and externally can be formed between the steel structure column 101 and the I-beam 102. This fixed structural net in the above technical solution can improve the connection stability between the steel structure column 101 and the I-beam 102, thereby preventing loosening or deformation between the steel structure column 101 and the I-beam 102 due to external forces. Furthermore, the internal connection structure between the steel structure column 101 and the I-beam 102 can further restrict the displacement of the I-beam 102, thereby reducing the impact of vibration on the connection.

[0020] A rectangular push block 115 is provided on both sides inside the metal column 3 and is slidably connected to it, and the surface of the rectangular push block 115 facing the L-shaped metal rod 111 is the first inclined surface 116. A locking rod 117 is provided on one side of the rectangular push block 115, and the surface of the locking rod 117 facing the rectangular push block 115 is a second inclined surface 122; a slot 118 is provided on the outer side of the top end of the locking rod 117, located on the inner wall of the reinforcing through hole 112, the outer surface of the top end of the locking rod 117 is in contact with the inner wall of the slot 118, and the top end of the locking rod 117 is slidably connected to the slot 118; during the process of inserting the L-shaped metal rod 111 into the connecting groove 114, the L-shaped metal rod 111 will contact the first inclined surface on the outer surface of the rectangular push block 115. As the L-shaped metal rod 111 penetrates deeper into the inclined surface 116, the rectangular push block 115 will be pushed outward under the action of the first inclined surface 116. During the outward pushing process, the rectangular push block 115 will contact the second inclined surface 122 located on the outer surface of the locking rod 117 and push the locking rod 117 towards the inside of the slot 118 located on the inner wall of the reinforcing through hole 112. When the L-shaped metal rod 111 completely passes the rectangular push block 115, the top end of the locking rod 117 will also be completely inserted into the inside of the slot 118. The clamping rod 117 is made of alloy steel in one piece. By inserting the clamping rod 117 into the slot 118, the strip-shaped reinforcing head 113 can be fixed inside the reinforcing through hole 112 by the material properties of the clamping rod 117 itself, which is made of alloy steel. As long as the top end of the clamping rod 117 does not break from other positions under the action of external force, the strip-shaped reinforcing head 113 cannot be pulled out from the reinforcing through hole 112. The connection strength between the steel structure column 101 and the I-beam 102 is further improved by the above technical solution.

[0021] A metal rod 119 is fixed inside the strip-shaped reinforcing head 113 on one side of the clamping rod 117. A positioning spring 121 is movably sleeved on one side of the outer surface of the metal rod 119. One end of the positioning spring 121 is connected to a connecting positioning sleeve 120 movably sleeved on the outer surface of the metal rod 119, and the surface of the connecting positioning sleeve 120 facing the clamping rod 117 is fixed to the clamping rod 117. The spring force of the positioning spring 121 ensures that the clamping rod 117 is completely inside the strip-shaped reinforcing head 113 before it is pushed by the L-shaped metal rod 111. The above technical solution can prevent the clamping rod 117 located on the lower side inside the strip-shaped reinforcing head 113 from moving to the outside of the strip-shaped reinforcing head 113 under the action of gravity, thus avoiding the situation where the clamping rod 117 located on the lower side inside the strip-shaped reinforcing head 113 moves to the outside of the strip-shaped reinforcing head 113 and obstructs the insertion operation of the strip-shaped reinforcing head 113.

[0022] The L-shaped metal rod 111 has a strip groove 104 on the outer surface of the steel structure column 101. A strip filling plate 105 is provided on one side of the strip groove 104. A fixing plate 106 is fixed on one side of the outer surface of the strip filling plate 105. A fixing through hole 107 is provided on both sides of the outer surface of the fixing plate 106, and a first fixing bolt 108 is provided on one side of each of the two fixing through holes 107. After the fixed structure mesh between the steel structure column 101 and the I-shaped steel 102 is formed, the strip filling plate 105 is inserted into the inside of the strip groove 104. Then, the fixing plate 106 and the strip filling plate 105 fixed to the fixing plate 106 are fixed by the first fixing bolt 108 and the fixing through hole 107. The above technical solution can fill the strip groove 104 for the L-shaped metal rod 111 to move up and down, thereby preventing the overall strength of the steel structure column 101 from being affected by the strip groove 104 on its outer surface.

[0023] From top to bottom, the outer surface of the top end of the first loop-shaped lifting frame 109 and the outer surface of the bottom end of the second loop-shaped lifting frame 109 are each fitted with a ring of second fixing bolts 110. The loop-shaped lifting frame 109 is fixed to the steel structure column 101 by the second fixing bolts 110. After the inside of the strip groove 104 is filled, multiple second fixing bolts 110 are used to fix the two loop-shaped lifting frames 109. By fixing the loop-shaped lifting frames 109, it is possible to prevent the loop-shaped lifting frames 109 from moving up and down on their own, which would cause the internal connection structure between the steel structure column 101 and the I-beam 102 to break.

[0024] Each pair of I-beam fixing bolts 103 is provided with a bolt locking mechanism on one side. The bolt locking mechanism includes a bolt locking strip metal shell 2 and a quick installation mechanism. Both sides of the bolt locking strip metal shell 2 are equipped with a metal column 3 through roller bearings. The metal column 3 is provided with a hexagonal groove 4 on the face facing the I-beam fixing bolt 103, and the shape of the inner wall of the hexagonal groove 4 corresponds to the shape of the hexagonal bolt head of the I-beam fixing bolt 103. Both sides of the outer surface of the metal column 3 are provided with a screw groove 5. The screw groove 5 is provided with a locking pointed screw 6. One side of the two locking pointed screws 6 is provided with an annular rubber plate 7 fixed inside the bolt locking strip metal shell 2, and the position of the annular rubber plate 7 corresponds to the position of the screw head of the locking pointed screw 6. After the I-shaped steel 102 is fixed, the two hexagonal grooves 4 on the two metal columns 3 located inside the same bolt locking strip metal shell 2 are respectively aligned with the hexagonal bolt heads of the two corresponding I-shaped steel fixing bolts 103.

[0025] The quick installation mechanism includes a square fixing metal head 10. The square fixing metal head 10 has a spring groove 14 inside. The spring groove 14 contains a spring 11. A rectangular fixing block 12 is connected to both the upper and lower end faces of the spring 11. One side of the outer surface of the rectangular fixing block 12 is a third inclined surface 13. A square mounting groove 8 is provided on one side of the square fixing metal head 10, located on the outer surface of the I-shaped steel 102 and corresponding to its position. The inner wall of the square mounting groove 8 has a square cross-section, and the shape of the inner wall of the square mounting groove 8 corresponds to the shape of the square fixing metal head 10. Both sides of the inner wall of the square mounting groove 8 are provided with a rectangular fixing groove 9, whose position corresponds to two rectangular fixing blocks 12 located on the outer surface of the square fixing metal head 10. When the hexagonal groove 4 is aligned with the hexagonal bolt head of the I-shaped steel fixing bolt 103, the bolt locking strip metal shell 2 is pushed towards the square mounting groove 8. As the bolt locking strip metal shell 2 moves, the bolt locking strip metal shell 2 is fixed to the outer surface of the bolt locking strip metal shell 2. The square fixing metal head 10 on the surface will be inserted into the square mounting groove 8. As the square fixing metal head 10 goes deeper, the third inclined surface 13 of the outer surface of the two rectangular fixing blocks 12 on the outer surface of the square fixing metal head 10 will contact the entrance of the square mounting groove 8. When the two contact, but the square fixing metal head 10 is still being pushed inward, the rectangular fixing blocks 12 will be pushed inward and squeeze the spring 11 connected to them. When the square fixing metal head 10 is completely inserted into the square mounting groove 8, the rectangular fixing blocks 12 can be inserted into the rectangular fixing groove 9 by the reaction force of the squeezed spring 11, thereby fixing the bolt locking strip metal shell 2. During the process of fixing the bolt-locking strip metal housing 2, the hexagonal bolt heads of the two I-beam bolts 103 will also enter the two hexagonal slots 4 located on the outer surface of the two metal pillars 3 respectively. After the bolt-locking strip metal housing 2 is installed, use a screwdriver to rotate the locking pointed screws 6 located in the two screw slots 5 on the outer surface of the metal pillars 3 until the top end of the locking pointed screws 6 is drilled into the annular rubber plate 7 fixed inside the bolt-locking strip metal housing 2. After the locking pointed screws 6 enter the annular rubber plate 7, the metal pillars 3 can be fixed. After the metal pillars 3 are fixed, their hexagonal bolt heads are inserted into the hexagonal slots 4 on the outer surface of the metal pillars 3. The I-beam fixing bolts 103 inside the side groove 4 will also be fixed. Through the above technical solution, the I-beam fixing bolts 103 used to initially fix the steel structure column 101 and the I-beam 102 can be locked and sealed, thereby reducing the external corrosion damage to the I-beam fixing bolts 103 and improving the service life of this connection assembly in marine or chemical environments. At the same time, by locking the I-beam fixing bolts 103 to prevent them from rotating, the connection between the steel structure column 101 and the I-beam 102 can be made more secure, thereby enhancing the integrity of the entire structure. This enhanced integrity can improve the performance of the structure under load, reduce stress concentration, and extend the service life of the structure. The square mounting groove 8, with its square cross-section, prevents the bolts from locking the strip metal casing 2 from rotating after installation.

[0026] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention.

10. A method of using a steel structure connection component, characterized in that: A method of using a steel structure connection component according to any one of claims 1-9 includes the following steps; Step A: When it is necessary to install the I-beam (102), align the strip-shaped reinforcing head (113) fixed to the outer surface of the I-beam (102) with the reinforcing through hole (112) located on the outer surface of the steel structure column (101), and then insert it until the face of the I-beam (102) facing the steel structure column (101) is in contact with the steel structure column (101). After the two are in contact, use the I-beam fixing bolt (103) to fix the I-beam (102) to the outer surface of the steel structure column (101) by the commonly used bolt fixing method. Step B: After the I-beam (102) is fixed to the outer surface of the steel structure column (101) by the I-beam fixing bolt (103), the two loop lifting frames (109) that are respectively movably sleeved on the outer surface of the steel structure column (101) are pushed towards the I-beam (102). During the movement of the loop lifting frame (109) towards the I-beam (102), the L-shaped metal rod (111) fixed on the inner wall of the loop lifting frame (109) will be inserted into the connecting groove (114) located on the outer surface of the strip reinforcement head (113). When the L-shaped metal rod (111) is inserted into the connecting groove (114), a fixed structural network that is synchronously connected inside and outside can be formed between the steel structure column (101) and the I-beam (102). Step C: After the I-beam (102) is fixed, align the two hexagonal slots (4) on the two metal columns (3) inside the same bolt-locking strip metal shell (2) with the hexagonal bolt heads of the corresponding two I-beam fixing bolts (103). Then, use the quick-installation mechanism to fix the bolt-locking strip metal shell (2) to the outside of the hexagonal bolt heads of the two I-beam fixing bolts (103). During the installation of the bolt-locking strip metal shell (2), the hexagonal bolt heads of the two I-beam fixing bolts (103) will also enter the two hexagonal slots on the outer surfaces of the two metal columns (3). Inside 4), after the bolt locking strip metal shell (2) is installed, use a screwdriver to rotate the locking pointed screw (6) inside the two screw slots (5) on the outer surface of the metal column (3) until the top end of the locking pointed screw (6) is drilled into the annular rubber plate (7) fixed inside the bolt locking strip metal shell (2). When the locking pointed screw (6) enters the annular rubber plate (7), the metal column (3) can be fixed. When the metal column (3) is fixed, the I-shaped fixing bolt (103) inserted into the hexagonal slot (4) on the outer surface of the metal column (3) will also be fixed.
