Description

Technical Field

[0001] The invention relates to the technical field of steel structure connection, and in particular to a high-safety assembled steel structure connector. Background Art

[0002] With the development of construction technology and material science, more types of connectors and technologies have emerged, such as high-strength friction bolt connections, self-tapping screw connections, clip-type connections, prestressed anchor systems, etc. Prefabricated steel structure is a modern construction technology that constructs buildings by prefabricating steel components in factories and then transporting them to construction sites for assembly. This method not only improves construction efficiency and reduces on-site operation time, but also helps to improve building quality and reduce environmental pollution. In order to ensure the safety and stability of prefabricated steel structures, the selection and design of connectors are crucial.

[0003] After searching, the utility model with authorization announcement number CN218580840U discloses a high-security prefabricated building steel structure connection node, including a first steel column, a third steel column is installed on the top of the first steel column, a lower flange is fixed on the outer wall of the first steel column near the end of the third steel column, and an upper flange is fixed on the outer wall of the third steel column near the end of the first steel column. The connection node is quickly installed by a combination of a flange and a locking bolt, and the risk of rainwater erosion is reduced by a sealing ring; but there are still some shortcomings in actual application.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0026] Embodiment 1: A high-security assembled steel structure connector, such as Figure 1-Figure 4As shown, it includes a mounting frame 3, which is fixedly assembled on the base column 1 to be connected by bolts; it also includes: a connecting frame plate 4, which is provided with four and circumferentially assembled on the four side outer walls of the mounting frame 3, the top side of the connecting frame plate 4 and the side away from the mounting frame 3 are both open, and the outer periphery of the connecting frame plate 4 is fixedly welded with a bolt plate 41, and the bolt plate 41 is provided with locking screw holes 411. The connecting frame plate 4 is fixed to the mounting frame 3 by driving bolts into the locking screw holes 411 of the bolt plate 41. The connecting frame plate 4 is used to The steel column 2 is connected; the assembly plate 42 is slidably assembled on the inner bottom of the connecting frame plate 4, and a second bolt hole 43 is opened on the assembly plate 42. The second bolt hole 43 of the assembly plate 42 is used to drive the bolts into the steel column 2 to complete the assembly; the sliding plate 44 has sliding grooves on both sides of the inner wall of the connecting frame plate 4, and the sliding plate 44 is slidably assembled in the sliding groove of the connecting frame plate 4. The sliding plate 44 and the assembly plate 42 are fixedly connected; the viscous damper 5 is provided with multiple groups and is arranged between the connecting frame plate 4 and the sliding plate 44. One end of the viscous damper 5 is connected by The first component 51 is fixedly connected to the sliding plate 44, and the other end of the viscous damper 5 is fixedly connected to the connecting frame plate 4 through the second connecting component 52. The viscous damper 5 is used to reduce the structural stability of the assembly plate 42 and the sliding plate 44 in the connecting frame plate 4, and improve the stability of the steel column 2 assembled to the base column 1; the offset detection component 6, the top surface of the assembly plate 42 is provided with a plurality of mounting grooves 45, and the mounting grooves 45 of the assembly plate 42 are provided with offset detection components 6. The offset detection component 6 is used to monitor the stability of the steel column 2 assembled in the connecting frame plate 4. The assembly position of the steel column 2 is confirmed on the base column 1 by installing the sleeve frame 3, and the connecting frame plate 4 is fixedly installed on the installing sleeve frame 3. The steel column 2 is fixedly installed on the assembly plate 42 of the connecting frame plate 4, and the assembly plate 42 and the sliding plate 44 are used to slide in the slide groove of the connecting frame plate 4, so that the steel column 2 assembled inside the connecting frame plate 4 can provide a certain buffer distance when expanding or contracting, and cooperate with the viscous damper 5 to provide a shock-absorbing effect, so that the steel column 2 assembled on the base column 1 can improve the ability to resist earthquakes, wind loads or other dynamic forces.

[0027] like Figure 1 and Figure 2 As shown, the base column 1 is a square column, and a plurality of first bolt holes 31 are provided on all four sides of the frame of the mounting frame 3. The mounting frame 3 is fixed to the base column 1 by driving bolts through the first bolt holes 31; the steel column 2 is an "I"-shaped column, and a plurality of assembly bolt holes 21 are provided on the top surface of the steel column 2. The assembly bolt holes 21 are used to fix and support the ceiling panel assembled on the top surface of the steel column 2, so that the ceiling panel can be expanded and stably assembled on the steel column 2 of the connector.

[0028] like Figure 3-Figure 5As shown, the offset detection component 6 includes a pressure sensor 61, a spring 62 and a pad 63. The pressure sensor 61 is installed in the mounting groove 45 of the assembly plate 42. The pressure sensor 61 has a built-in controller for electrically triggering an external alarm. A spring 62 is arranged between the pressure sensor 61 and the assembly plate 42. A pad 63 is arranged on the pressure-sensitive diaphragm on the top of the pressure sensor 61. The pad 63 is located in the mounting groove 45 of the assembly plate 42 and contacts the corresponding steel column 2. The top surface of the pad 63 is higher than the top surface of the assembly plate 42. The steel column 2 on the assembly plate 42 is monitored in real time by the pressure sensor 61. When the steel column 2 on the assembly plate 42 becomes loose, the pressure between the pressure sensor 61 and the pad 63 will change abnormally, thereby triggering an external alarm through the built-in controller of the pressure sensor 61 to alert the user that the steel column 2 on the assembly plate 42 is loose.

[0029] When the steel column 2 is assembled using the present steel structure connector, the installer confirms the position where the steel column 2 needs to be assembled on the base column 1, and then aligns the installation sleeve frame 3 with the plurality of first bolt holes 31 to the position where the base column 1 needs to be assembled, and firmly fixes the two together with bolts. The installation sleeve frame 3 assembled on the base column 1 will provide a stable foundation for all subsequent components. Then the four connecting frame plates 4 are circumferentially assembled to the four side outer walls of the installation sleeve frame 3. Specifically, the locking screw holes 411 on the bolt plates 41 welded on the outer periphery of the connecting frame plates 4 are driven into the bolts to the corresponding opening structures on the installation sleeve frame 3 to ensure the stability and reliability of the connecting frame plates 4 to be firmly assembled to the outer walls of the installation sleeve frame 3. Then, the butt end of the steel column 2 to be assembled is placed in the connecting frame plate 4 and placed on the assembly plate 42 in the connecting frame plate 4. At this time, the steel column 2 is fixed to the assembly plate 42 by a plurality of bolts through the second bolt holes 43 opened on the assembly plate 42. Since the assembly plate 42 and the sliding plate 44 are connected by a slide groove, such a design The assembly plate 42 is allowed to respond to the expansion or contraction of the steel column 2 caused by temperature changes, thereby avoiding stress concentration. At the same time, through the viscous damper 5 between the connecting frame plate 4 and the sliding plate 44, when the steel column 2 assembled on the connecting frame plate 4 encounters an earthquake, wind load or other dynamic force, the viscous damper 5 can absorb energy, reduce vibration transmission, and protect the entire structure from damage, thereby improving the stability and risk resistance of the present connector to the assembled steel structure. When the steel column 2 is assembled on the assembly plate 42, the steel column 2 will be squeezed on the pad 63 inside the mounting groove 45 of the assembly plate 42, so that the pad 63 overcomes the elastic force of the spring 62 and presses down on the pressure-sensitive diaphragm of the pressure sensor 61. The pressure of the steel column 2 on the assembly plate 42 is monitored in real time by the pressure sensor 61. When the bolts of the steel column 2 assembled to the assembly plate 42 become loose or deviate due to other reasons, the built-in controller of the pressure sensor 61 triggers the external alarm to sound an alarm, ensuring that the installer can promptly detect the loosening of the connector and take measures to maintain the safety of the structure.

[0030] Embodiment 2: Based on embodiment 1, Figure 1 , Figure 6 and Figure 7 As shown, a sealing component 7 is provided on the outer side of the connecting frame plate 4, and the sealing component 7 is used for injecting glue to seal the locking screw hole 411 on the connecting frame plate 4. The sealing component 7 includes a guide block 71, a glue injection frame 73 and a glue injection valve 74. The guide block 71 is screwed into the bolt through the third bolt hole 72 and assembled to the outer wall of the connecting frame plate 4. The guide blocks 71 are distributed on both sides of the outer wall of the connecting frame plate 4. The glue injection frame 73 is a "U"-shaped frame and is slidably assembled on the outer wall of the connecting frame plate 4 through the guide blocks 71. The glue injection frame 73 covers the periphery of the bolt plate 41, and there is a certain interval space between the glue injection frame 73 and the bolt plate 41. The glue injection valve 74 is installed on the glue injection frame 73. The glue injection valve 74 is used to inject sealant into the bolt plate 41 inside the glue injection frame 73, and the screw holes of the bolt plate 41 are filled with sealant to improve the waterproofness and adhesion of the bolts driven into the bolt plate 41, thereby improving the service life of the connecting frame plate 4 and the bolt plate 41 on the mounting sleeve frame 3.

[0031] like Figure 1 , Figure 6 and Figure 7 As shown, a reinforcement component 8 is provided on the outer wall of the mounting frame 3, and the reinforcement component 8 is used to reinforce the glue injection frame 73. The reinforcement component 8 includes a fixing frame 81, a threaded sleeve 82, a threaded rod 83 and a connecting ring 85. The fixing frame 81 is provided with multiple groups and is respectively fixed on the four outer walls of the mounting frame 3. The fixing frame 81 is fixedly welded with a threaded sleeve 82, and a threaded rod 83 is installed in the threaded sleeve 82. The threaded rod 83 and the threaded sleeve 82 are threadedly adapted. The top of the threaded rod 83 is rotatably installed with a connecting ring 85, and the connecting ring 85 and the corresponding glue injection frame on the same side are connected. 73 are in contact, and the threaded rod 83 is screwed on the threaded sleeve 82 so that the connecting ring 85 on the threaded rod 83 can be tightly squeezed on the glue injection frame 73, so that the glue injection frame 73 can be firmly assembled to the periphery of the bolt plate 41, thereby improving the stability of the glue injection frame 73 after glue injection; the lower end of the threaded rod 83 is fixedly provided with a hexagonal nut 84, and the hexagonal nut 84 is adapted to be screwed with a specific hexagonal screwdriver, so that the threaded rod 83 in the threaded sleeve 82 cannot be easily screwed, thereby improving the support and reinforcement effect of the threaded rod 83 on the glue injection frame 73 through the connecting ring 85.

[0032] like Figure 1 and Figure 8 As shown, limit blocks 9 are fixedly assembled on both sides of the inner wall of the connecting frame plate 4, and docking holes 92 are opened on the connecting frame plate 4. The limit blocks 9 are screwed into the docking holes 92 of the connecting frame plate 4 through the fourth bolt holes 91, so that the limit blocks 9 can be fixedly assembled to the inner wall of the connecting frame plate 4. The limit blocks 9 are used to limit and support the steel columns 2 assembled on the assembly plate 42, thereby further improving the stability of the steel columns 2 assembled to the assembly plate 42.

[0033] After the bolt plate 41 on the connecting frame plate 4 is fixed to the mounting sleeve frame 3 by bolts, the guide blocks 71 are fixed to the two sides of the outer wall of the connecting frame plate 4 by the third bolt holes 72, and then the glue injection frame 73 is slidably installed on the outer wall of the connecting frame plate 4 by the guide blocks 71, so that the glue injection frame 73 is sealed around the bolt plate 41. At this time, there will be a certain spacing between the glue injection frame 73 and the corresponding bolt plate 41. At this time, by using a specific hexagonal screwdriver to screw the hexagonal nut 84 on the threaded rod 83, the threaded rod 83 is screwed into the threaded sleeve 82 on the fixing frame 81 in a threaded manner, and the glue injection frame 73 is pressed by the connecting ring 85 on the top. Since the threaded rod 83 and the connecting ring 85 are rotationally adapted, the screwed threaded rod 83 will drive the connecting ring 8 to move upward at the fixing frame 81. When the connecting ring 8 contacts the injection frame 73, it does not affect the continued rotation of the threaded rod 83 until the connecting ring 85 can be fastened and supported on the injection frame 73, thereby improving the stability of the injection frame 73 assembled to the periphery of the bolt plate 41, and then the injection valve 74 equipped with the injection frame 73 is used to accurately control the injection amount of the sealant so that the sealant can evenly fill the locking screw hole 411 on the bolt plate 41, thereby enhancing the waterproof performance while also improving the durability of the bolt connection. Before assembling the steel column 2 to the assembly plate 42, the limit block 9 is first fixed to the docking hole 92 of the connecting frame plate 4 through the fourth bolt hole 91. Since the steel column 2 is an "I"-shaped column, the limit blocks 9 assembled on both sides of the inner wall of the connecting frame plate 4 can support and limit the movement of the steel column 2 on the assembly plate 42, and cooperate with the steel column 2 to be fixed to the assembly plate 42 with bolts, thereby further ensuring the accuracy and stability of the steel column 2 after assembly.
