Technical Field

[0001] The present invention relates to the technical field of assembled steel structures, in particular to a quick-assembly frame of an assembled steel structure. Background Art

[0002] At present, in the construction industry, the building structure form is gradually developing. With the increasing utilization of space and the increasing height of buildings, and the increasing requirements of the country for the assembly rate of projects, the structural form is increasingly developing towards assembly and modularization. The composite structure has a high assembly rate and excellent mechanical properties, which makes it more and more frequently used in existing projects.

[0003] Existing technologies for connecting beams and columns in frame structures generally use on-site welding or on-site welding with high-strength bolts. This requires welding at height, is difficult to operate, requires high welding technology, is dangerous, and requires a lot of on-site welding work. Furthermore, welding or welding with high-strength bolts still requires workers to install the bolts at the beam-column joint all at once, which reduces the assembly speed of the joint. Furthermore, this method only secures the beam-column joint with bolts. If the bolts are damaged or loosened by external erosion, they may reduce the service life of the beam-column joint, thereby affecting the stability and safety of the frame structure. Summary of the Invention

[0004] In view of the above defects in the prior art, the present invention provides a quick-assembly frame of an assembled steel structure to solve the problems of difficult operation, high cost, low efficiency and the like in beam-column assembly in traditional frame structures.

[0005] The present invention is achieved by adopting the following technical solutions:

[0006] The harness includes a first end, a second end, and a second end, wherein the harness includes a first end, a second end, and a second end, wherein the harness includes a first end, a second end, and a second end, wherein the harness includes a first end, a second end, and a second end, wherein the first end, the second end, and the second end, are connected to each other in an axial direction.

[0007] Furthermore, each side surface of the node connecting member is provided with a node limiting groove extending in the axial direction, the open end of each node limiting groove is set downward, and the node limiting groove is connected to the mortise hole in a one-to-one correspondence, and the node connecting member is inserted into the splicing node cavity from top to bottom to be connected and fixed with the multiple first assembly beams extending to the splicing node cavity through the node limiting groove.

[0008] Furthermore, the node connector is an integrally formed structure.

[0010] Furthermore, the node limiting groove and the connecting end of the first assembly beam are clearance-fitted.

[0011] Furthermore, the depth of the node limiting groove is greater than the depth of the first assembly beam.

[0012] Furthermore, overlapping grooves are provided on multiple side surfaces of the top of the lower column, and clamping grooves are opened at positions corresponding to the overlapping grooves at the bottom of the upper column. The bottom surface of the connecting end of the first assembly beam extends vertically upward to form a first mortise and tenon. The connecting end of the first assembly beam is overlapped in the overlapping groove and the first mortise and tenon are mortised with the bottom surface of the overlapping groove. The top surface of the connecting end of the first assembly beam is clamped by the clamping groove.

[0013] Furthermore, the bottom surface of the connecting end portion of the second assembly beam extends vertically upward to form a second mortise and tenon, the connecting end portion of the second assembly beam is placed in the connecting groove, and the second mortise and tenon are mortise-jointed with the bottom surface of the connecting groove.

[0014] Furthermore, the top connecting member includes a cover portion for covering the opening and a limiting portion extending into the inner cavity of the upper column.

This not only achieves the purpose of quick assembly, but also does not require welding or bolt connections throughout the entire process, greatly simplifying the assembly process and greatly improving construction efficiency. It also enhances the stability of the structure and reduces assembly costs. At the same time, the node connectors are hidden inside the assembly columns, achieving concealed installation, which not only retains the aesthetics of the mortise and tenon joints but also achieves a high-strength functional connection. At the same time, through the arrangement of the node connectors and top connectors, under dynamic loads or earthquakes, the looseness and gap of the nodes can amplify the deformation capacity, increase the structural damping coefficient, and thus reduce the response of the superstructure, truly realizing node deformation energy dissipation and ensuring structural stability under dynamic impact.

DETAILED DESCRIPTION

[0029] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concepts of the example embodiments to those skilled in the art. Identical reference numerals in the drawings represent identical or similar structures, and thus repeated descriptions thereof will be omitted.

[0030] The words expressing positions and directions described in the present invention are all explained with reference to the accompanying drawings as examples, but can be modified as needed, and all such modifications are within the scope of protection of the present invention.

[0031] like Figures 1 to 10 As shown, a quick-assembly frame of an assembled steel structure provided by the present invention includes a plurality of vertically arranged assembly columns 10, a plurality of first assembly beams 21 and a plurality of second assembly beams 22 arranged horizontally and spliced with the assembly columns 10, a node connector 30 and a top connector 40 located inside the assembly columns 10, the assembly columns 10 include an upper column 11 and a lower column 12 arranged up and down and coaxially spliced, the upper column 11 and the lower column 12 are formed with a plurality of mortises at the splicing position, and the connecting end of the first assembly beam 21 is connected to the assembly column 10 at the mortises. Mortise and tenon connection, the node connector 30 is located in the splicing node cavity of the upper column 11 and the lower column 12 and simultaneously limits and fixes the multiple first assembly beams 21 extending to the splicing node cavity in the axial direction, the top of the upper column 11 is open and is provided with a plurality of connecting grooves 112, the connecting end of the second assembly beam 22 is connected to the assembly column 10 at the connecting groove 112, and the top connector 40 is used to cover the open position and simultaneously limit and fix the multiple second assembly beams 22 extending to the inside of the upper column 11 in the axial direction.

[0032] In this embodiment, the first assembly beam 21 and the assembly column 10 are first connected at the node connection by a mortise and tenon method to achieve rapid pre-fixation of the first assembly beam 21 and the assembly column 10. The mortise and tenon connection method can provide self-locking force in multiple directions, so that it can effectively resist horizontal and vertical loads. Thereafter, the first assembly beam 21 and the assembly column 10 are reinforced and connected at the node connection by using the node connector 30. The multiple first assembly beams 21 are limited and fixed in the axial direction by the node connector 30, which can further enhance the stability of the beam-column connection, prevent displacement or deformation due to external force, and greatly enhance the firmness of the frame structure; similarly, the connecting end of the second assembly beam 22 and the upper column 11 are first connected by a mortise and tenon method to achieve rapid pre-fixation of the second assembly beam 22 and the assembly column 10, and then the stability of the beam-column connection is enhanced by the top connector 40 to prevent displacement or deformation due to external force. At the same time, the top connector 40 can also seal the opening of the upper column 11 to achieve a waterproof and anti-debris effect.

[0033] The assembly column 10 of the quick-assembly frame of the present invention is connected to the first assembly beam 21 and the second assembly beam 22 by mortise and tenon connection and auxiliary node connector 30 and top connector 40. This not only achieves the purpose of quick assembly, but also does not require welding or bolt connection throughout the entire process, greatly simplifying the assembly process and greatly improving construction efficiency. At the same time, it enhances the stability of the structure and reduces assembly costs. At the same time, the node connector 30 is hidden inside the assembly column 10, achieving concealed installation, which not only retains the aesthetics of the mortise and tenon joints, but also achieves a high-strength functional connection. At the same time, through the setting of the node connector 30 and the top connector 40, a certain degree of sliding deformation capability is allowed between the beams and columns. Under dynamic loads or earthquakes, the looseness and gap of the nodes can amplify the deformation capability and increase the structural damping coefficient, thereby reducing the response of the upper structure, truly achieving node deformation energy dissipation, and ensuring structural stability under dynamic impact. The assembly column 10 adopts a split splicing structure, which can be prefabricated in sections and assembled on site, reducing on-site construction errors. The split splicing facilitates later heightening or expansion. At the same time, by setting energy-absorbing nodes at the segmented splicing, it can absorb seismic energy and improve structural ductility.

[0034] It can be understood that the assembly column 10, the first assembly beam 21 and the second assembly beam 22 of the present invention can be produced in a standardized manner, that is, they can be prefabricated in the factory and assembled on site to improve construction efficiency. The corresponding node connectors 30 and the top connectors 40 are designed with corresponding adaptability and standardized to achieve mass production of components, which is conducive to reducing production costs and can be directly replaced during maintenance.

[0035] As a preferred embodiment, each side of the node connector 30 is provided with a node limiting groove 31 extending in the axial direction, the open end of each node limiting groove 31 is set downward, and the node limiting groove 31 is connected to the mortise hole in a one-to-one correspondence. The node connector 30 is inserted into the splicing node cavity from top to bottom to be plugged and fixed with the multiple first assembly beams 21 extending to the splicing node cavity through the node limiting groove 31.

[0036] In this embodiment, the node connector 30 is plugged and fixed to the connecting end of the first assembly beam 21 through the node limiting groove 31, thereby limiting and fixing the first assembly beam 21 in the axial direction, ensuring the stability of the beam-column node; in addition, the node connector 30 adopts plug-in assembly, does not require welding, has strong operability, and is easy and quick to install.

[0037] It should be noted that the shape of the node limiting groove 31 of the present invention is compatible with the shape of the first assembly beam 21, wherein the node connector 30 of this embodiment is preferably a hollow column tube. Of course, in other embodiments, the node connector 30 can also be formed by welding structures such as steel plates, angle steels, channel steels, square tubes or round steels.

[0038] As a preferred embodiment, the node connector 30 is an integrally formed structure, which facilitates production and processing.

[0039] As a preferred embodiment, two adjacent side surfaces of the node connector 30 are connected by welding.

[0040] In this embodiment, the side surfaces of the node connector 30 are preferably square, and the side surfaces are welded together to form a hollow column. This allows different node connectors 30 to be customized according to different needs, which is highly flexible.

[0041] As a preferred embodiment, the node limit groove 31 is clearance-fitted with the connecting end of the first assembly beam 21. This allows a certain degree of slippage and deformation capability at the beam-column node. Under dynamic loads or earthquakes, the looseness and clearance of the node can amplify the deformation capability, increase the structural damping coefficient, and thus reduce the response of the superstructure, truly achieving node deformation energy dissipation and ensuring structural stability under dynamic impact.

[0042] As a preferred embodiment, the depth of the node limiting groove 31 is greater than the depth of the first assembly beam 21. This ensures that the first assembly beam 21 is completely clamped in the node limiting groove 31, which can further enhance the connection performance of the node area.

[0043] As a preferred embodiment, overlapping grooves 121 are provided on multiple side surfaces of the top of the lower section column 12, and clamping grooves 111 are opened at the positions corresponding to the overlapping grooves 121 at the bottom of the upper section column 11. The bottom surface of the connecting end of the first assembly beam 21 extends vertically upward to form a first mortise and tenon 210. The connecting end of the first assembly beam 21 is overlapped in the overlapping groove 121 and the first mortise and tenon 210 and the bottom surface of the overlapping groove 121 are mortised with each other, and the top surface of the connecting end of the first assembly beam 21 is clamped by the clamping groove 111.

[0044] In this embodiment, by cooperating with the overlapping groove 121 and the clamping groove 111, the connecting end of the first assembly beam 21 is locked in the axial direction of the assembly column 10. At the same time, the first mortise and tenon groove 210 and the bottom surface of the overlapping groove 121 are mortised with each other, thereby improving the connection performance between the beam and the column, ensuring the stability and reliability of the mortise and tenon connection between the beam and the column, and enhancing the seismic and bending resistance.

[0045] It can be understood that the depth and shape of the overlapping groove 121 and the clamping groove 111 can be changed, and the cross-sectional size and shape of the first assembly beam 21 can be changed.

[0046] As a preferred embodiment, the bottom surface of the connecting end of the second assembly beam 22 extends vertically upward to form a second mortise and tenon 220, the connecting end of the second assembly beam 22 is placed in the connecting groove 112 and the second mortise and tenon 220 and the bottom surface of the connecting groove 112 are mortise-jointed with each other.

[0047] In this embodiment, by cooperating with the connecting groove 112 and the top connecting piece 40, the connecting end of the second assembly beam 22 is locked in the axial direction of the assembly column 10. At the same time, the second mortise and tenon groove 220 and the bottom surface of the connecting groove 112 are mortised with each other, thereby improving the connection performance between the beam and the column and ensuring the stability and reliability of the mortise and tenon connection between the beam and the column.

[0048] It can be understood that the depth and shape of the connecting groove 112 can be varied, and the cross-sectional size and shape of the second assembly beam 22 can be varied.

[0049] As a preferred embodiment, the depth of the connecting groove 112 is greater than the depth of the second assembly beam 22. In this way, the connection end of the second assembly beam 22 is prevented from affecting the installation of the top connector 40.

[0050] As a preferred embodiment, the top connecting member 40 includes a cover portion 41 for covering the opening and a limiting portion 42 extending into the inner cavity of the upper column 11. The limiting portion 42 is hollow cylindrical and has a top limiting groove 43 on its side. When the top connecting member 40 is inserted downward into the inner cavity of the upper column 11, the top limiting groove 43 of the limiting portion 42 is plugged and fixed to the multiple second assembly beams 22 extending into the interior of the upper column 11.

[0051] In this embodiment, multiple second assembly beams 22 are inserted and fixed together through top retaining grooves 43, enhancing the stability of the beam-column connection, preventing displacement or deformation due to external forces, and significantly strengthening the robustness of the frame structure. Cover 41 shields the opening of the upper column 11, preventing rainwater and debris from leaking into the assembly column 10. The retaining portion 42 and cover 41 are integrally structured, facilitating the production of the top connector 40 and reducing costs.

[0052] As a preferred embodiment, the bottom of the lower column 12 is provided with a column foot 13. The diameter of the column foot 13 is larger than that of the lower column 12, and fixing holes are provided at the four corners of the column foot 13. The column foot 13 supports and secures the entire construction scaffolding, providing a simple and stable fixation method. Preferably, the column foot 13 is fixed in place using chemical anchors or expansion bolts.

[0053] As a preferred embodiment, it also includes a plurality of purlins 50. The first assembly beam 21 and the second assembly beam 22 are each provided with a plurality of spaced-apart sleeves 23 along their length direction. A corbel is provided in the sleeve 23. The corbel at least partially extends out of the sleeve 23. Both ends of the purlin 50 are respectively provided with through holes connected to the corbels.

[0054] In this embodiment, purlins 50 are connected between two adjacent first assembly beams 21 and two adjacent second assembly beams 22, which can enhance the firmness of the entire structure; and the purlins 50 are fixed to the first assembly beams 21 and the second assembly beams 22 by connecting them with corbels and through holes, without the need for welding or screwing, which simplifies the assembly process and reduces the assembly cost.
