Description

Technical Field

[0001] This application relates to the technical field of construction, and particularly to a connection structure between a steel pipe column and a steel pipe folded beam and a building thereof. Background Art

[0002] With the accelerating pace of urbanization, the social aesthetic of building space is also gradually improving. Along with the demands of society, owners, and the architectural profession for building effects, the building method of using a steel pipe folded beam with a bending structure as the roof and forming a support mechanism with inclined connecting columns is increasing. In the prior art, the connecting column and the steel pipe folded beam are usually connected by a strong connection around the perimeter.

[0003] However, through repeated calculations, it is found that in the prior art, due to the existence of the top moment of the inclined connecting column, the normal stress of the connecting column is relatively large, and the cross-section of the connecting column also becomes relatively large accordingly, which limits the selection of the connecting column and affects the use of building functions. In addition, in this situation, the beams and columns around the connection node have spatial angles. If the prior art method is used, it will inevitably lead to a large number of welds at the node, and the situation of weld intersections is also relatively common, which undoubtedly increases the difficulty of steel structure processing and construction, and the quality is also difficult to guarantee.

[0004] Therefore, how to design a connection structure between an inclined column and a steel pipe folded beam to release the top moment of the column, reduce the column cross-section, and at the same time reduce the difficulty of steel structure processing and installation has become a problem to be solved in this application.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] The technical solutions of the present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0031] In a first aspect, as Figures 1-4 shown, the present application provides a connection structure between a steel pipe column and a steel pipe folded beam. The steel pipe folded beam 1 includes a bending structure, and the steel pipe column 2 is obliquely connected to the steel pipe folded beam 1 at the bending structure. That is to say, in the application scenario of the present application, it is not a simple connection between a horizontal steel pipe beam and a vertical steel pipe column, but a connection structure for an "oblique" steel pipe column and a steel pipe beam with a bent "angle".

[0032] In a specific embodiment, as Figure 1 shown, the bending structure of the steel pipe folded beam 1 includes a plurality of bending structures A and B that undulate up and down. The steel pipe column 2 is obliquely connected and fixed to the steel pipe folded beam 1 at the bending structure A or B. It can be understood that the inclination direction of the steel pipe column 2 is consistent with the direction along the connection force of the bending structure and the steel pipe column 2. For example, if the steel pipe column 2 is inclined at 45° to the upper left, it should be located at the lower right of the bending structure A of the steel pipe folded beam 1.

[0033] Regarding the connection structure between the steel pipe column 2 and the steel pipe folded beam 1 at the bending structure, it includes: a steel pipe column end ear plate 3, a folded beam middle ear plate 4, and a pin shaft 5. Among them, the steel pipe column end ear plate 3 is arranged at the connection end of the steel pipe column 2 and includes a column fixing hole 31; the folded beam middle ear plate 4 is arranged at the bending structure of the steel pipe folded beam 1 and includes a folded beam connection surface 41 and a steel pipe column connection surface 42, and the steel pipe column connection surface 42 includes a plate fixing hole 43; the pin shaft 5 passes through the column fixing hole 31 and the plate fixing hole 43 to fixedly connect the steel pipe column end ear plate 3 and the folded beam middle ear plate 4, thereby fixedly connecting the steel pipe column 2 and the steel pipe folded beam 1.

[0034] Regarding the above-mentioned steel pipe column end ear plate 3, the steel pipe column end ear plate 3 includes two ear plate structures, and the folded beam middle ear plate 4 is inserted into the two ear plate structures of the steel pipe column end ear plate 3. Align the two column fixing holes 31 and the plate fixing hole 43, and make the pin shaft 5 pass through the two column fixing holes 31 and the plate fixing hole 43 to fixedly connect the steel pipe column end ear plate 3 and the folded beam middle ear plate 4.

[0035] And, again, as Figures 1-2 shown, the inclined steel pipe column 2 has an inclined axis. Since the steel pipe folded beam 1 has a certain width, its bending structure includes an upper bending point A1 and a lower bending point A2. The inclined axis of the steel pipe column 2 corresponds to the upper bending point A1 of the bending structure of the steel pipe folded beam 1 to obtain the opening position of the plate fixing hole 43 in the steel pipe column 2 connection surface, so that the upper bending point of the steel pipe folded beam 1 bending structure, the plate fixing hole 43, and the inclined axis of the steel pipe column 2 are in a straight line.

[0036] Regarding the above-mentioned folded beam middle ear plate 4, the folded beam middle ear plate 4 in this application can be understood as a rib plate with a unique shape. Generally speaking, the middle ear plate can be set as a square, but in this application, in order to adapt to the characteristics of the spatial angle of the folded beam itself and the hollow rectangular cross-section of the folded beam, the shape of the folded beam middle ear plate 4 is as Figure 3 shown, including: a folded beam connection surface 41 and a steel pipe column connection surface 42. The folded beam connection surface 41 is used to fixedly connect the steel pipe folded beam 1, and the steel pipe column connection surface 42 is used to fixedly connect the steel pipe column end ear plate 3. The folded beam connection surface 41 and the steel pipe column connection surface 42 are shown by different shaded areas in Figure 3 the figure.

[0037] In a specific embodiment, the shape of the folded beam connection surface 41 is consistent with the shape of the bending structure of the steel pipe folded beam 1. That is, the upper side of the folded beam connection surface 41 of the gusset plate 4 in the folded beam includes a bending structure consistent with the bending structure of the steel pipe folded beam 1. The steel pipe column connection surface 42 is arranged as a "convex corner" shape protruding towards the steel pipe column 2 relative to the bending structure. And the plate fixing hole 43 is arranged in the "convex corner" protruding towards the steel pipe column 2 to facilitate docking with the steel pipe column 2. It can be understood that the folded beam connection surface 41 and the steel pipe column connection surface 42 are an integral part, integrally forming the gusset plate 4 in the folded beam, and there is no cross-section.

[0038] In order to bear the local compression and local bending moment of the end gusset plate 3 of the steel pipe column on the inclined top of the steel pipe column 2, a set of orthogonal structural composite plates can also be added inside the steel pipe at the top of the steel pipe column 2. This composite plate can jointly bear the force with the top end of the steel pipe column 2 to ensure that the top of the steel pipe column 2 will not be crushed by the load of the steel pipe folded beam 1.

[0039] In a specific embodiment, as Figure 4 shown, the steel pipe column 2 further includes: a transverse inner partition 21, a vertical rib plate 22, and a steel pipe column top plate 23. The steel pipe column 2 is hollow. The transverse inner partition 21 and the vertical rib plate 22 are arranged inside the steel pipe column to form the above-mentioned composite plate. And, the transverse inner partition 21 is horizontally arranged at the connecting end inside the steel pipe column 2, the vertical rib plate 22 is vertically and perpendicularly arranged on the transverse inner partition 21 and connected to the steel pipe column top plate 23. The steel pipe column top plate 23 is horizontally arranged at the cross-section of the connecting end of the steel pipe column 2, one end is perpendicularly connected to the end gusset plate 3 of the steel pipe column, and the other end is perpendicularly connected to the vertical rib plate 22, so that the steel pipe column top plate 23, the transverse inner partition 21, and the vertical rib plate 22 jointly bear the force.

[0040] It can be understood that between the transverse inner partition 21, the vertical rib plate 22, and the steel pipe column top plate 23, and between the steel pipe column top plate 23 and the end gusset plate 3 of the steel pipe column, welding connection is preferably used, and other fixing connection methods can also be used, but the structural stability needs to be ensured.

[0041] Regarding the connection structure of the above-mentioned steel pipe column and the steel pipe folded beam, as Figure 1 shown, in a specific embodiment, the steel pipe column 2 is a Y-shaped steel pipe column, including two upward-branching connecting ends. The steel pipe folded beam 1 includes a plurality of undulating bending structures. The two connecting ends of the Y-shaped steel pipe column 2 are obliquely connected to the steel pipe folded beam 1 at two lower bending structures, which can make the connection structure of the steel pipe column and the steel pipe folded beam more stable.

[0042] Regarding the fixed connection method between the gusset plate 4 in the folded beam and the steel pipe folded beam 1, in a specific embodiment, the gusset plate 4 in the folded beam is welded and connected at the folded beam connection surface 41 and the bent structure of the steel pipe folded beam 1. Preferably, the gusset plate 4 in the folded beam is welded and connected to the upper and lower sides of the bent structure of the steel pipe folded beam 1 at the folded beam connection surface 41 respectively.

[0043] For the connection structure between the steel pipe column and the steel pipe folded beam provided by this application, the steel pipe column and the steel pipe folded beam are obliquely connected at the bent structure. By using the steel pipe column end ear plate arranged at the connection end of the steel pipe column and the gusset plate in the folded beam arranged at the bent structure of the steel pipe folded beam, the inclined steel pipe column and the steel pipe folded beam are fixed and connected by a pin shaft, realizing the complex connection of multi-angle members at a single node, releasing the bending moment at the top of the steel pipe column, reducing the cross-section of the steel pipe column, while reducing the workload of on-site welding of complex joints and improving the project quality.

[0044] In a second aspect, this application also provides a building, including at least one connection structure between the steel pipe column and the steel pipe folded beam in the first aspect above, where the steel pipe column is used to play a longitudinal support role in the building, and the steel pipe folded beam is used for the roof of the building.

[0045] The other preferred embodiments, the technical problems that can be solved, and the technical effects that can be achieved in the second aspect of this application are the same as those in the first aspect, and will not be elaborated here.

[0046] The preferred embodiments of this application have been described in detail above. However, this application is not limited to the specific details in the above embodiments. Within the scope of the technical concept of this application, various simple modifications can be made to the technical solutions of this application, and these simple modifications all belong to the protection scope of this application.

[0047] In addition, it should be noted that, in the case of no contradiction, the various specific technical features described in the above specific embodiments can be combined in any suitable way. To avoid unnecessary repetition, this application will not separately describe various possible combination methods.

[0048] In addition, any combination can be made between various different embodiments of this application, as long as it does not violate the idea of this application, it should also be regarded as the content disclosed by this invention.
