Description

Technical Field

[0001] This invention relates to the field of building engineering technology, and specifically to a steel structure building assembly and connection component. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure mainly consists of steel beams, steel columns, steel trusses, and other components made of shaped steel and steel plates. Steel structures are primarily constructed from steel and are one of the main types of building structures. Steel is characterized by high strength, light weight, good overall rigidity, and strong deformation capacity, making it particularly suitable for constructing large-span, super-high, and super-heavy buildings. It has good homogeneity and isotropy, making it an ideal elastic body that best conforms to the basic assumptions of general engineering mechanics. It also has good plasticity and toughness, allowing for large deformations and excellent resistance to dynamic loads. Construction periods are short, and its high degree of industrialization allows for highly mechanized and specialized production.

[0003] When assembling steel structures, it is often necessary to consider the connecting components at the splicing nodes. These components need to connect the upper and lower columns and the horizontal beams. Existing connecting components generally use bolts and nuts for connection. For I-shaped connecting nodes, the connection part is generally in the web and flange areas. This structure connects to the I-beam by cantilevering support plates on the central body. However, the fixing strength is limited and cannot meet people's needs. The fixing method often requires tightening nuts, resulting in low installation efficiency. The connection strength relies on multiple bolts for support, which has limited support strength. Furthermore, the bolts and nuts separate during disassembly, making construction troublesome. During installation, workers need to carry bolts and nuts, resulting in low work efficiency. Therefore, it is necessary to study a steel structure building assembly connecting component. Summary of the Invention

[0004] Therefore, the purpose of this invention is to provide a steel structure building assembly connection component that effectively solves the problems of limited connection strength between existing connection components and surrounding connecting I-beams, and cumbersome assembly.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: a steel structure building assembly and connection component, including a central body, side splicing bodies and vertical fastening parts, wherein the central body has corresponding and non-through I-shaped sockets at the top and bottom, and upper and lower I-shaped steel columns are appropriately installed in the upper and lower sockets.

[0006] The vertical fastening part includes a fastening screw, a fastening sleeve, a pressure block, a drive rod, a spring, a rocker arm, and a fastening block; fastening sleeves are fixed in the two abdominal regions of the socket, a drive sleeve is provided at the lower part of the fastening sleeve, the pressure block is adapted to be installed in the drive sleeve, a drive rod is fixed at its bottom, the spring is fitted on the drive rod and is located between the drive sleeve and the pressure block, a conical block is fixed at the bottom of the drive rod, the rocker arm is hinged to the outside of the drive sleeve, a fastening block is provided on its outside, the fastening block has a fastening surface on its outside and a drive inclined surface adapted to the conical block inside, the fastening screw is threaded into the fastening sleeve and presses the pressure block inward and downward, and the fastening surface can extend into the socket;

[0007] The side splicing body includes splicing frames and fixing blocks; the splicing frames are fixed at intervals on the side of the central body, and cross-shaped fixing blocks are fixed inside the splicing frames. A clamping area for inserting side I-beams is formed between the two splicing frames. Side plates are provided on both sides of the I-beams. The side plates and the upper and lower flanges of the I-beams are respectively fitted and clamped on the outer side and upper and lower frame of the splicing frames, and mounting holes are provided at the corresponding positions of the three. The cross-shaped structure of the fixing blocks corresponds to the mounting holes and has a connecting screw sleeve inside. The connecting screw is connected to the connecting screw sleeve through the mounting hole.

[0008] Furthermore, three fastening blocks are provided, extending towards the belly and two wings of the I-shaped socket respectively.

[0009] Furthermore, the bottom of the drive sleeve is sealed, and the drive rod is adapted to extend out from the sealed end.

[0010] Furthermore, the central body has a square structure, and a connecting frame is provided between the two splicing frames at the corner. The connecting frame is adapted to fit and fit the edge of the splicing frame and the outer side of the central body.

[0011] Furthermore, when the side plate abuts against the side of the splicing frame, the side of the I-beam abuts against the side of the central body.

[0012] Furthermore, the splicing frame is provided with connecting sleeves on its upper and lower sides. The connecting sleeves protrude outward from the splicing frame, connecting the outer perimeter of the splicing frame together, and forming a mounting area on the upper part of the splicing frame that is compatible with the flange of the I-beam.

[0013] Furthermore, a reinforcing rod is provided between the upper connecting sleeve and the lower connecting sleeve.

[0014] Furthermore, the end of the fastening block is provided with a friction surface, and the rocker arm is connected to the hinge seat arranged on the drive sleeve via a torsion spring.

[0015] Furthermore, a slot is provided at the insertion part of the I-beam column, and when the I-beam is inserted into the socket, the slot is adapted to the outer side of the fastening block.

[0016] The beneficial effects of the above technical solution are as follows: The present invention is based on a central body, with corresponding insertion slots on the upper and lower sides of the central body. The insertion slots are used to connect the upper and lower I-beam columns and are fastened by vertical fastening parts. During the fastening process, the present invention is connected to the fastening sleeve by a fastening screw and pushes against the pressure plate when moving downward, overcoming the spring force and compressing the pressure plate downward, thereby causing the conical block to move downward. By utilizing the inclined surface of the conical block and the fastening block, the fastening block moves synchronously towards the web and flange of the I-beam. The contact or snapping force is used to fix the upper and lower I-beam columns. One fastening screw can drive three fastening blocks to push against the corresponding side.

[0017] Regarding the connection of the side beams, the present invention has a splicing frame fixed on the side of the central body, a fixing block arranged inside the splicing frame, and a connecting screw sleeve provided inside the fixing block. Structurally, a side plate is provided inside the I-beam to be spliced. The splicing frame fits tightly with the two side flanges and side plates of the I-beam through its frame and is provided with mounting holes. By arranging connecting screws in the holes, the three sides of the I-beam can be connected with the three frame sides of the splicing frame and correspondingly connected to the connecting screw sleeves inside the fixing frame.

[0018] Meanwhile, in order to further enhance the stability of the structure and improve the support strength of the side splicing body, the present invention connects each splicing frame by connecting plates or connecting sleeves, so that the splicing frames are interconnected, increasing the connection nodes with the central body, providing a basis for welding, improving the connection strength between the splicing frame and the central body, and enabling it to withstand higher load stress.

[0019] Therefore, this invention uses a fastening structure to securely install vertical I-beams. By arranging splicing frames on the side of the central body, the I-beam structure can be supported, allowing for full contact with the I-beams. Bolts are then applied to the contact surface for fastening. This results in a structure with high strength, a wide distribution of connection points, strong stability, and high construction efficiency. It provides convenience, is lightweight, uses less material, and offers significant economic benefits. Attached Figure Description

Detailed Implementation

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0030] Example 1: This example aims to provide a steel structure building assembly connection component, which is mainly used for splicing steel structures. In view of the problems of limited connection strength between the connection component and the surrounding connecting I-beams in the prior art and the troublesome assembly, this example provides a support-type steel structure building assembly connection component.

[0031] like Figure 1-5 The image shows a steel structure building assembly and connection component, including a central body 1, side splicing bodies, and vertical fastening parts. The central body 1 has corresponding, non-through I-shaped sockets 2 at the top and bottom of its center. An upper I-beam steel column 4 and a lower I-beam steel column 5 are appropriately installed in the upper and lower sockets 2. In this embodiment, the central body 1 has a square structure with a hollow interior to facilitate the arrangement of the vertical fastening parts inside. Specifically, the sockets 2 are arranged on the upper and lower sides of the central body 1. Structurally, the entire side of the central body 1 is flat and fixed to the structure.

[0032] To fix the vertical upper H-beam column 4 and lower H-beam column 5, the vertical fastening part in this embodiment includes a fastening screw 6, a fastening sleeve 7, a pressure block 9, a drive rod 11, a spring 10, a swing rod 13, and a fastening block 14. The fastening sleeve 7 is fixed in the two abdominal areas of the insertion port 2. The end of the fastening sleeve 7 has a fastening port for screwing the fastening screw 6 in. The lower part of the fastening sleeve 7 is provided with a drive sleeve 8. The pressure block 9 is adapted to be installed in the drive sleeve 8. The bottom of the drive sleeve 9 is fixed with a drive rod 11. In this structure, the fastening sleeve 7 is in the upper part and the drive sleeve 8 is in the lower part. The inner diameter of the drive sleeve 8 is larger than that of the fastening sleeve. The inner wall of the fastening sleeve 7 is provided with a threaded structure. The lower part of the drive sleeve 8 is a smooth cylindrical structure with a sealed bottom plate. The bottom of the drive sleeve is sealed, and the drive rod is adapted to be led out from the sealed part.

[0033] To facilitate the rebound of the fastening block after the elastic structure is released, in this embodiment, the spring 10 is fitted onto the drive rod 11 and positioned between the drive sleeve 8 and the pressure block 9. A conical block 12 is fixed to the bottom of the drive rod 11. The swing rod 13 is hinged to the outside of the drive sleeve 8, and a fastening block 14 is provided on its outside. The outside of the fastening block 14 has a fastening surface that can be tightly attached to the inner wall of the I-beam. Inside the fastening block 14, there is a drive ramp that matches the conical block. In implementation, the drive ramp is inclined inward, and the ramp of the conical block is inclined outward. The two ramps have the same inclination. When the conical block moves downward, it can force the fastening frame to unfold outward. After the driving force applied to the pressure plate disappears, the conical block moves upward, while the fastening block, lacking a supporting force, will naturally swing downward. A torsion spring can also be applied to the end of the swing rod to facilitate the reset of the fastening block.

[0034] The fastening screw 6 is threaded into the fastening sleeve 7 and presses downward against the pressure block 9. The fastening surface can extend into the socket 2. In this embodiment, the fastening screw is threaded into the fastening sleeve and abuts against the pressure plate 9 when moving downward, overcoming the elastic force of the spring 10 and compressing the pressure plate downward, thereby causing the conical block 12 to move downward. Using the inclined surface of the conical block 12 and the fastening block 14, the fastening block 14 moves synchronously towards the web and flange of the I-beam. The contact or snapping force is used to fix the upper and lower I-beam columns. One fastening screw can drive three fastening blocks to abut against the corresponding side. The contact fastening is based on friction, and there is a friction surface on the outside of the fastening block. The snapping fastening is based on a slot on the side of the I-beam. When the I-beam is inserted into the bottom of the socket, the slot matches the fastening block. By driving the pressure plate downward, the fastening block can be snapped into the slot.

[0035] To splice and fix the side I-beams, in this embodiment, the side splicing body includes a splicing frame 17 and a fixing block 18; as shown... Figure 5As shown, splicing frames 17 are fixed at intervals on the sides of the central body 1, and cross-shaped fixing blocks 18 are fixed inside the splicing frames 17. A clamping area 24 for inserting side I-beams is formed between the two splicing frames 17. The clamping area 24 allows the web of the I-beam to fit through, and its upper flange 22 is supported on the upper part of the splicing frame 17, while the lower flange 21 is located at the lower part of the splicing frame 17. Side plates 16 are provided on both sides of the I-beam, and the side plates 16 correspond to the upper and lower flanges of the I-beam, respectively. The card is mounted on the outer side and the upper and lower edges of the splicing frame 17, and mounting holes 20 are provided at the corresponding positions of the three. The cross-shaped structure of the fixing block 18 corresponds to the mounting hole and has a connecting screw sleeve inside. The connecting screw 19 is connected to the connecting screw sleeve through the mounting hole. In implementation, four connecting screws are arranged at the fixing points on each side. The structural stability is improved by fixing at multiple points. In this embodiment, the fixing blocks and splicing frame are hollowed out in the structure, making the structure lightweight. The fixing block structure is arranged at the corresponding connection point.

[0036] When the side plate 16 abuts against the side of the splicing frame 17, the side of the I-beam abuts against the side of the central body 1. At the same time, the side of the side plate 16 is directly attached to the side area of ​​the splicing frame, and connecting screws 19 are applied at three splicing points. The connecting screws are connected to the fixed frame built into the splicing frame 17. In this embodiment, the splicing frame 17 is fixed on the side of the central body 1. The splicing frame is a steel frame when assembled. The internal fixing block can not only improve the structural strength, but also provide installation points for connection. The fixing block 18 is arranged in the splicing frame. The fixing block 18 is provided with connecting screw sleeve. Structurally, the side plate is provided in the I-beam to be spliced. The splicing frame is tightly attached to the two side flanges and side plates of the I-beam through its frame. It is provided with mounting holes. By arranging connecting screws in them, the three sides of the I-beam can be connected to the three frame sides of the splicing frame and correspondingly connected to the connecting screw sleeves in the fixed frame.

[0037] To address the low construction efficiency caused by relying heavily on bolts to bear loads in existing technologies, this embodiment provides a support-and-clamp structure for stabilizing transverse I-beams. In use, the central body 1 is first assembled onto the lower I-beam column, and the lower I-beam column is fixed using the fastening bolts on both sides of the lower insertion port 2, providing installation points for the crossbeam arrangement. Then, the web of the I-beam is aligned with the clamping area of ​​the two splicing frames, with its upper flange supporting the upper part of the splicing frame and its lower flange tightly against the lower part of the splicing frame. The I-beam is then pushed inwards, causing its side plates to abut against the sides of the splicing frame. At this point, each installation... The holes correspond to each other, and connecting bolts are applied into the mounting holes to achieve the assembly of the structure. In this embodiment, when fixing the I-beam, the I-beam is fastened from three sides, resulting in strong structural stability. Since the construction points are all on the outside, construction is convenient. The whole structure can be prefabricated in the factory, and only threaded connections are needed on site. This can effectively avoid various defects caused by on-site welding. The assembly relationship is standardized, the structure is stable, and the construction quality is guaranteed while greatly accelerating the construction speed. Each unit module can be prefabricated in the factory and then transported to the construction site for assembly and splicing using bolts.

[0038] Example 2 is basically the same as Example 1, except that the specific structure of the fastening block is further explained in this example.

[0039] In this embodiment, three fastening blocks 14 are provided in the structure, and they extend to the belly and two wings of the I-shaped socket 2 respectively.

[0040] like Figure 6-7 As shown in the illustration, this embodiment has three hinge seats arranged on the outside of the fastening sleeve. The swing rod 13 is hinged to the hinge seats. By adjusting the mating slope of the fastening block 14 and the conical block 12, it is ensured that after applying the same angle to the swing rod 13, it can be abutted against each point of the I-beam. Using the mating slope of the conical block 12 and the fastening block 14, the fastening block 14 moves synchronously towards the web and flange of the I-beam. The contact or snapping force is used to fix the upper and lower I-beam columns. A fastening screw can drive the three fastening blocks to abut against the corresponding side.

[0041] Thus, this embodiment can drive the conical block downward by applying the fastening screw 6 at a single point, using the driving force of the fastening screw, and drive the three swing arms to swing simultaneously, so that the three fastening blocks can fit against the inner side of the I-beam. The fastening points are configured to fit the I-beam splicing structure. The clamping force between the fastening block 14 and the I-beam is used to stabilize the vertical I-beam column. Furthermore, by applying fixing points simultaneously on both sides of the I-beam, the stabilization effect is good, and it has a good pull-out resistance effect.

[0042] Example 3 is basically the same as Example 1, except that the structure of the central body 1 is further explained in this example.

[0043] In implementation, the central body 1 has a square structure, and a connecting frame 23 is provided between the two splicing frames at the corner. The connecting frame 23 is adapted and fitted to the frame of the splicing frame 17 and the outer side of the central body 1. In this embodiment, the two splicing frames at the corner can be connected into one unit through the connecting frame 23, so that it can have good stability during the assembly process, and each load-bearing part can share the load.

[0044] Example 4 is basically the same as Example 1, except that the structure of the splicing frame is further explained in this example.

[0045] This implementation example Figure 8 As shown in the diagram, the splicing frame 17 is provided with connecting sleeves on the upper and lower sides, with the upper connecting sleeve 25 and the lower connecting sleeve 26 located at the top. The connecting sleeves protrude outward from the splicing frame, connecting the outer perimeter of the splicing frame together, and forming a clamping area at the top of the splicing frame that is compatible with the flange of the I-beam. A reinforcing rod is provided between the upper and lower connecting sleeves.

[0046] This embodiment further enhances the stability of the structure and improves the support strength of the side splicing body. By connecting the splicing frames with connecting sleeves, the splicing frames are interconnected, increasing the connection nodes with the central body 1, providing a basis for welding, and improving the connection strength between the splicing frame and the central body 1, enabling it to withstand higher load stress.

[0047] When the side plate rests against the splicing frame, the inner wall of the I-beam rests against the connecting sleeve. In this implementation structure, the connecting sleeve is an integral structure that can be fully connected to the central body and welded. The structure has high strength and can withstand large loads.
