Description

Technical Field

[0001] This invention relates to the field of steel structure building technology, specifically to a beam-column connection structure and a steel structure. Background Technology

[0002] Steel structure beams and columns are structures made of steel materials and are one of the main types of building structures. They have advantages such as high strength, light weight, good seismic performance, high degree of industrialization, energy saving and environmental protection. Steel structure beams and columns are often used as supports in the construction of some greenhouses. When connecting steel structure beams and columns, a connecting structure is needed to connect the steel structure beams and columns.

[0003] Chinese patent document CN117051990B discloses a steel beam-column connection structure and a steel structure, including a beam-column body, a sleeve, an I-beam connector, and nuts. The sleeve is fixedly installed on the beam-column body, and an I-beam connector that can be inserted into the sleeve is provided next to the sleeve. Nuts are symmetrically fixedly installed inside the beam-column body. The sleeve is connected to two nuts. The I-beam connector is fixed by connecting the nuts to a threaded rod. When the threaded rod is turned, a rigid washer pushes the push block, causing the wedge-shaped top block to move away from each other and drive the limiting block to insert into the corresponding limiting groove. This provides additional reinforcement between the I-beam connector and the sleeve, thereby preventing the I-beam connector from loosening.

[0004] However, in the above scheme, after the sleeve and the I-beam connector are inserted, they need to be fixed in two places by threaded rods, which makes it inconvenient to quickly install the steel structure beams and columns and reduces the installation efficiency. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the problem of low installation efficiency of steel beam-column connection structure in the prior art, thereby providing a beam-column connection structure and a steel structure.

[0006] To address the aforementioned technical problems, this invention provides a beam-column connection structure, comprising: a limiting frame, a fixed inner core, and a mounting block; the limiting frame is fixedly connected to a first connecting body; the fixed inner core is fixedly connected to the first connecting body, and the fixed inner core is located within the limiting frame and has a gap between it and the inner sidewall of the limiting frame; the mounting block is fixedly connected to a second connecting body, and the mounting block is adapted to be embedded in the gap between the limiting frame and the fixed inner core; the limiting frame, the fixed inner core, and the mounting block have concentrically arranged holes for connecting fasteners.

[0007] In use, the mounting block is embedded in the gap between the limiting frame and the fixed inner core. The limiting groove guides and limits the mounting block, ensuring concentric alignment of the holes on the limiting frame, fixed inner core, and mounting block. This facilitates the connection of fasteners to the holes, allowing for quick installation of the second connector onto the first connector, thus improving installation efficiency. By reinforcing the connection with fasteners locked into the holes, the connection strength between the mounting block and the limiting frame and fixed inner core is enhanced, thereby improving the stability of the connection between the first and second connectors. The beam-column connection structure provided by this invention solves the problem of low installation efficiency in existing steel structure beam-column connection structures.

[0008] Optionally, the limiting frame has an opening on its upper or side, and the mounting block is inserted into the limiting frame through the opening. With this configuration, the mounting block slides into the limiting frame, and the limiting groove guides and limits the mounting block, enabling the second connector to be quickly installed on the first connector. This ensures that the hole structures on the limiting frame, the fixed inner core, and the mounting block are concentrically aligned, facilitating the connection of fasteners to the hole structures and improving installation efficiency.

[0009] Optionally, the limiting frame has a limiting stop on the insertion path of the mounting block, and the mounting block has a strip groove for inserting the limiting stop. With the above configuration, when the mounting block is slidably inserted into the limiting frame, the limiting stop slides into the strip groove, which can guide and limit the insertion path of the mounting block, and can also block the mounting block to prevent it from coming out of the limiting frame.

[0010] Optionally, the upper side of the limiting frame has an opening, and the two symmetrical sides of the limiting frame have a first hole structure for fasteners to pass through. The limiting stop is located on the side of the first hole structure away from the first connecting body. The mounting block is vertically connected to the end of the second connecting body. The two symmetrical sides of the mounting block have a second hole structure for fasteners to pass through. The strip groove is located on the side of the second hole structure closer to the second connecting body. The fixing inner core is vertically connected to the first connecting body. The two symmetrical sides of the fixing inner core have a third hole structure for fasteners to pass through. The first hole structure, the second hole structure, and the third hole structure are all arranged in multiples in a vertical direction. With the above configuration, the mounting block is inserted vertically through the opening on the top of the limiting frame, and can quickly take position under the weight of the second connector. The bottom plate of the limiting frame can support the mounting block, and the limiting stop provides a blocking fit on the side of the mounting block away from the first connector, bringing the mounting block closer to the first connector and aligning the first hole structure, the second hole structure, and the third hole structure, facilitating connection with fasteners. Multiple first hole structures, second hole structures, and third hole structures are arranged vertically, which can ensure that the mounting block, the limiting frame, and the fixed inner core are subjected to uniform force and improve the connection strength.

[0011] Optionally, the limiting stop consists of two symmetrically arranged strips. This arrangement allows the mounting block to be easily inserted into the limiting frame, preventing jamming during insertion.

[0012] Optionally, the connection position between the mounting block and the second connector has two symmetrically arranged triangular support blocks; the fastener includes a screw, the threaded end of which is connected to an annular brush, and the hole structure on the fixed inner core has an internal thread for engaging with the fastener. Through the above arrangement, the triangular support blocks can strengthen the connection between the second connector and the mounting block, increasing the support force on the second connector; when the fastener connects the mounting block, the limiting frame, and the hole structure on the fixed inner core, the screw is threadedly connected to the hole structure on the fixed inner core, preventing the fastener from slipping out of the hole structure and improving the connection strength; simultaneously with the threaded connection, the annular brush on the screw can clean the inner wall of the hole structure, preventing impurities from adhering inside the hole structure and affecting the threaded connection.

[0013] This invention provides a steel structure including the beam-column connection structure described in any of the above embodiments. Due to the use of the beam-column connection structure, it possesses any of the aforementioned advantages.

[0014] Optionally, in the beam-column connection structure, the first connector is a supporting column, and the second connector is a supporting beam. With this configuration, the supporting beam can be quickly installed on the supporting column using the beam-column connection structure.

[0015] Optionally, a camera assembly is connected to the bottom of the support beam. The camera assembly includes: a horizontal moving mechanism having a groove disposed at the bottom of the support beam, a slider, a first motor, and a lead screw disposed in the groove, the lead screw being connected to the drive end of the first motor, and the slider being threadedly connected to the lead screw; a second motor disposed at the bottom of the slider, and a rotating disk disposed at the drive end of the second motor; and a monitoring module disposed at the bottom of the rotating disk.

[0016] With the above settings, when it is necessary to adjust the horizontal position of the monitoring module on the support beam, the first motor drives the lead screw to rotate, and the slider converts the rotational motion into linear motion under the limiting action of the slide groove, so that the slider moves horizontally along the slide groove, and the slider drives the monitoring module to move along the length direction of the support beam; when it is necessary to adjust the angle of the monitoring module, the second motor drives the rotating disk to rotate the monitoring module; this can expand the monitoring range of the monitoring module.

[0017] Optionally, the slider is provided with a threaded hole for connecting to the lead screw, and the slider is provided with an annular dust removal brush, which is coaxially arranged with the threaded hole, and the end of the dust removal brush contacts the outer surface of the lead screw. With the above arrangement, when the slider moves along the slide groove, it drives the dust removal brush to move along the lead screw, cleaning the outer surface of the lead screw and preventing dust or impurities from adhering to the outer surface of the lead screw and affecting the movement of the slider.

[0030] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention.

[0033] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0034] This embodiment provides a beam-column connection structure that can be installed quickly, used for connecting support beams and support columns in steel structures.

[0035] like Figure 1-3 The diagram illustrates a specific implementation of a beam-column connection structure provided in this embodiment, comprising: a limiting frame 1, a fixed inner core 2, and a mounting block 3. The limiting frame 1 is fixedly connected to a first connecting body 5; the fixed inner core 2 is fixedly connected to the first connecting body 5, and the fixed inner core 2 is located within the limiting frame 1 and has gaps between it and the two symmetrical inner sidewalls of the limiting frame 1; the mounting block 3 is fixedly connected to a second connecting body 6, and the mounting block 3 is adapted to be embedded in the gap between the limiting frame 1 and the fixed inner core 2; the limiting frame 1, the fixed inner core 2, and the mounting block 3 have concentrically arranged hole structures for connecting fasteners 4.

[0036] In use, the mounting block 3 is embedded in the gap between the limiting frame 1 and the fixed inner core 2. The limiting groove guides and limits the mounting block 3, ensuring that the hole structures on the limiting frame 1, the fixed inner core 2, and the mounting block 3 are concentrically aligned. This facilitates the connection of the fastener 4 to the hole structure, enabling the second connector 6 to be quickly installed on the first connector 5, thus improving installation efficiency. By locking the fastener 4 into the hole structure for reinforcement, the connection strength between the mounting block 3 and the limiting frame 1 and the fixed inner core 2 can be improved, thereby enhancing the stability of the connection between the first connector 5 and the second connector 6. The beam-column connection structure provided in this embodiment solves the problem of low installation efficiency in existing steel structure beam-column connection structures.

[0037] Specifically, the mounting block 3 is provided with a groove structure 31 for embedding the fixed inner core 2.

[0038] like Figure 1-3 As shown, in the beam-column connection structure provided in this embodiment, the upper or side of the limiting frame 1 has an opening, and the mounting block 3 is inserted into the limiting frame 1 through the opening. The mounting block 3 slides into the limiting frame 1, and the limiting groove guides and limits the mounting block 3, enabling the second connecting body 6 to be quickly installed on the first connecting body 5, so that the hole structures on the limiting frame 1, the fixed inner core 2, and the mounting block 3 are concentrically aligned, facilitating the connection of the hole structure to the fastener 4, thereby improving installation efficiency. Specifically, the limiting frame 1 is formed by a support plate 11 and two fixing plates 12, and the hole structure is set on the fixing plate 12. In addition, as an alternative embodiment, the opening on the upper or side of the limiting frame 1 is omitted, and the mounting block 3 is inserted into the limiting frame 1 along the length direction of the second connecting body 6.

[0039] like Figure 1-3As shown, in the beam-column connection structure provided in this embodiment, the limiting frame 1 has a limiting stop 13 on the insertion path of the mounting block 3, and the mounting block 3 has a strip groove 32 for inserting the limiting stop 13. When the mounting block 3 is slidably inserted into the limiting frame 1, the limiting stop 13 is slidably inserted into the strip groove, which can guide and limit the insertion path of the mounting block 3, and can also block the mounting block 3 to prevent it from coming out of the limiting frame 1. In addition, as an alternative embodiment, the limiting stop 13 can be omitted, and between the connecting fasteners 4, construction personnel can prevent the mounting block 3 from coming out of the limiting frame 1 by means of machinery or manpower.

[0040] like Figure 2 As shown, in the beam-column connection structure provided in this embodiment, the upper side of the limiting frame 1 has an opening, and the two symmetrical sides of the limiting frame 1 have a first hole structure 14 for passing through the fastener 4. The limiting stop 13 is located on the side of the first hole structure 14 away from the first connecting body 5. The mounting block 3 is vertically connected to the end of the second connecting body 6. The two symmetrical sides of the mounting block 3 have a second hole structure 33 for passing through the fastener 4. The strip groove 32 is located on the side of the second hole structure 33 close to the second connecting body 6. The fixed inner core 2 is vertically connected to the first connecting body 5. The two symmetrical sides of the fixed inner core 2 have a third hole structure 21 for passing through the fastener 4. The first hole structure 14, the second hole structure 33 and the third hole structure 21 are all arranged in multiples along the vertical direction. The mounting block 3 is inserted vertically through the opening on the upper part of the limiting frame 1, and can be quickly positioned by the gravity of the second connecting body 6. The bottom plate of the limiting frame 1 can support the mounting block 3. The limiting stop 13 forms a blocking engagement on the side of the mounting block 3 away from the first connecting body 5, so that the mounting block 3 is closer to the first connecting body 5, and the first hole structure 14, the second hole structure 33 and the third hole structure 21 are aligned, which facilitates connection by the fastener 4. Multiple first hole structures 14, second hole structures 33 and third hole structures 21 are arranged in the vertical direction, which can make the mounting block 3, the limiting frame 1 and the fixed inner core 2 evenly stressed and improve the connection strength. In addition, as an alternative embodiment, the limiting stop 13 can also be set on the side of the first hole structure 14 near the first connecting body 5, and the strip groove can be set on the side of the second hole structure 33 away from the second connecting body 6.

[0041] Specifically, the inner sidewalls of the first hole structure 14, the second hole structure 33, and the third hole structure 21 may all be provided with internal threads, or one of the first hole structure 14, the second hole structure 33, and the third hole structure 21 may be provided with internal threads; or two of the first hole structure 14, the second hole structure 33, and the third hole structure 21 may be provided with internal threads.

[0042] like Figure 2 As shown, in the beam-column connection structure provided in this embodiment, the limiting stop 13 consists of two symmetrically arranged strips. These strips facilitate the insertion of the mounting block 3 into the limiting frame 1, preventing jamming during insertion. Alternatively, as an alternative implementation, the limiting stop 13 can also consist of multiple spaced-apart limiting protrusions.

[0043] like Figure 1 , Figure 2 , Figure 4 As shown, in the beam-column connection structure provided in this embodiment, the connection position between the mounting block 3 and the second connecting body 6 has two symmetrically arranged triangular support blocks 34; the fastener 4 includes a screw, the threaded end of which is connected to an annular brush 41, and the hole structure on the fixed inner core 2 has an internal thread for cooperating with the fastener 4. The triangular support blocks 34 can strengthen the connection strength between the second connecting body 6 and the mounting block 3, and improve the support force for the second connecting body 6; when the fastener 4 connects the mounting block 3, the limiting frame 1 and the hole structure on the fixed inner core 2, the screw is threadedly connected to the hole structure on the fixed inner core 2, which can prevent the fastener 4 from slipping out of the hole structure and improve the connection strength; at the same time as the threaded connection, the annular brush 41 on the screw can clean the inner wall of the hole structure, preventing impurities from adhering in the hole structure and affecting the threaded connection. Specifically, the threaded end of the screw is provided with a fixing block 42, and the annular brush 41 is provided on the outer wall of the fixing block 42. Alternatively, as an alternative implementation, the triangular support block 34 can be omitted, and two symmetrical triangular support plates 11 can be provided at the connection position between the mounting block 3 and the second connector 6; the annular brush 41 can also be omitted, and the inner wall of the hole structure can be cleaned by manual blowing before installation.

[0044] How to use:

[0045] like Figure 1As shown, in the beam-column connection structure provided in this embodiment, when in use, the mounting block 3 is slidably inserted into the limiting frame 1 from the opening on the upper side of the limiting frame 1, and the limiting stop 13 is slidably inserted into the gap between the strip groove 32 and the fixed inner core 2, so that the hole structures on the limiting frame 1, the fixed inner core 2 and the mounting block 3 are concentrically aligned, and the hole structures on the limiting frame 1, the fixed inner core 2 and the mounting block 3 are connected by fasteners 4 for reinforcement.

[0046] In addition, this embodiment also provides a steel structure that adopts the beam-column connection structure described in the above embodiments to realize the connection between the supporting beams and supporting columns in the steel structure.

[0047] like Figure 1 As shown, in the steel structure provided in this embodiment, in the beam-column connection structure, the first connector 5 is a supporting column, and the second connector 6 is a supporting beam. The supporting beam can be quickly installed on the supporting column using the aforementioned beam-column connection structure. Alternatively, as an alternative implementation, the first connector 5 can be a supporting beam, and the second connector 6 can be a supporting column.

[0048] like Figure 1 , Figure 5 , Figure 6 As shown, in the steel structure provided in this embodiment, a camera assembly is connected to the bottom of the support beam. The camera assembly includes: a horizontal moving mechanism 7, which has a slide groove 71 disposed at the bottom of the support beam. A slider 73, a first motor 74, and a lead screw 72 are disposed in the slide groove 71. The lead screw 72 is connected to the drive end of the first motor 74, and the slider 73 is threadedly connected to the lead screw 72; a second motor 8 is disposed at the bottom of the slider 73, and a rotating disk 81 is disposed at the drive end of the second motor 8; and a monitoring module 9 is disposed at the bottom of the rotating disk 81. When the horizontal position of the monitoring module 9 on the support beam needs to be adjusted, the first motor 74 drives the lead screw 72 to rotate. Under the limiting action of the slide groove 71, the slider 73 converts the rotational motion into linear motion, causing the slider 73 to move horizontally along the slide groove 71. The slider 73 then drives the monitoring module 9 to move along the length of the support beam. When the angle of the monitoring module 9 needs to be adjusted, the second motor 8 drives the rotating disk 81 to rotate the monitoring module 9, thus expanding the monitoring range of the monitoring module 9. Specifically, a mounting bracket 82 is provided on the rotating disk 81, and the monitoring module 9 is mounted on the mounting bracket 82. Alternatively, as an alternative implementation, the horizontal moving mechanism 7 and the second motor 8 can be omitted, and the monitoring module 9 can be directly mounted on the bottom of the support beam or the side surface of the support column.

[0049] like Figure 5 , Figure 7As shown, in the steel structure provided in this embodiment, the slider 73 is provided with a threaded hole for connecting the lead screw 72, and the slider 73 is provided with an annular dust removal brush 731. The dust removal brush 731 is coaxially arranged with the threaded hole, and the end of the dust removal brush 731 contacts the outer surface of the lead screw 72. When the slider 73 moves along the slide groove 71, it drives the dust removal brush 731 to move along the lead screw 72, cleaning the outer surface of the lead screw 72 by the dust removal brush 731, preventing dust or impurities from adhering to the outer surface of the lead screw 72 and affecting the movement of the slider 73. Alternatively, as an alternative embodiment, the dust removal brush 731 can be omitted, and the outer surface of the lead screw 72 can be cleaned manually.

[0050] like Figure 1 , Figure 5 As shown, in the steel structure provided in this embodiment, a protective shell 83 is provided at the bottom of the slider 73, and the second motor 8 is disposed inside the protective shell 83. The drive shaft of the second motor 8 extends from the bottom of the protective shell 83 and connects to the rotating disk 81. The protective shell 83 can protect the second motor 8. Alternatively, as an alternative embodiment, the protective shell 83 can be omitted, and the second motor 8 is exposed.

[0051] like Figure 8 In the steel structure provided in this embodiment, the protective shell 83 has an opening, and an openable and closable protective door 84 is provided at the opening. A hinge 85 is provided at the first end of the protective door 84 so that the first end of the protective door 84 is hinged to the protective shell 83. A fixing structure 86 is provided at the second end of the protective door 84 for locking the protective door 84. Alternatively, as an alternative embodiment, the hinge 85 can be omitted, and the protective door 84 can be detachably mounted on the protective shell 83 using fasteners.

[0052] like Figure 8 , Figure 9In the steel structure provided in this embodiment, the fixing structure 86 includes: a locking plate 861, a locking block 862, and a locking groove 864. The locking plate 861 is disposed on the side of the protective door 84 near the protective shell 83, and a groove is provided on the side of the locking plate 861 away from the hinge 85. The locking block 862 is disposed in the groove, and an elastic element 863 is disposed between the locking plate 861 and the locking block 862. The elastic element 863 has an elastic force that drives the locking block 862 away from the locking plate 861. The locking groove 864 is disposed on the protective shell 83 and is used to insert the locking plate 861. An avoidance hole 865 for exposing the locking block 862 is provided on the side wall of the locking groove 864. The side of the locking block 862 away from the protective door 84 is set as an inclined surface. When the protective door 84 is closed, the sidewall of the slot 864 moves along the inclined surface of the block 862, pushing the block 862 to compress the elastic member 863. The block 862 is embedded in the groove on the plate 861 until the protective door 84 closes the opening of the protective shell 83. The elastic member 863 drives the block 862 away from the plate 861, causing the block 862 to protrude from the clearance hole 865, thus achieving a latch lock. When the protective door 84 is opened, pressing the block 862 compresses the elastic member 863, and the block 862 is embedded in the groove on the plate 861. The plate 861 disengages from the slot 864, pulling the protective door 84 open. Alternatively, as an alternative implementation, the fixing structure 86 can also be configured as a magnetic locking structure.

[0053] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
