Description

Technical Field

[0001] The present invention relates to the technical field of building structures, and particularly to a connection node for a corrugated web roof beam. Background Art

[0002] Corrugated web steel beams have the advantages of good out-of-plane stiffness of the web, relatively high shear buckling strength, and steel consumption saving, and have been widely used in the fields of aviation and bridges, and are also gradually widely used in industrial plants.

[0003] Due to the "folding effect", the stiffness of the corrugated web in the direction parallel to the beam axis is very small and it can hardly bear the normal stress, which makes the flexural bearing capacity of the beam relatively low.

[0004] In the related art, it is difficult to ensure the reliable transfer of the axial force of the tie rod to the corrugated web roof beam at the connection node, and large deformation or local yield failure is likely to occur, resulting in a decrease in the stability of the overall structure. Moreover, the connection nodes between the corrugated web beam and the roof support are not universal with those of the flat web beam, resulting in poor interchangeability of components, which is not conducive to construction and maintenance.

[0005] Therefore, it is necessary to develop a new connection node for a corrugated web roof beam to improve some of the above problems existing in the related art. Summary of the Invention

[0006] The purpose of the present invention is to provide a connection node for a corrugated web roof beam, which can improve the flexural capacity of the corrugated web beam when the corrugated web beam bears the axial force of the tie rod.

[0007] The purpose of the present invention can be achieved through the following technical solutions:

[0008] A connection node for a corrugated web roof beam provided by the present invention includes a beam body, a first connecting plate and a tie rod; the tie rod is connected to the beam body through the first connecting plate; wherein, the web of the beam body is formed by connecting a flat plate and a corrugated plate, the first connecting plate connects the flat plate and the flange of the beam body, and the tie rod connects the first connecting plate, and is used to directly transfer the axial force of the tie rod to the flange and the flat plate through the first connecting plate to share the normal stress of the roof beam.

[0009] Further, both ends of the flat plate are respectively connected to the corrugated plate in the extending direction of the beam body.

[0010] Further, the height of the flat plate is the same as that of the corrugated plate, and both ends of the flat plate and the corrugated plate are respectively connected to the two side flanges in the vertical direction.

[0011] Further, the height of the flat plate is less than the height of the corrugated plate. One end of the flat plate is connected to the flange in the vertical direction, and the other end is connected to the other flange through the corrugated plate.

[0012] Further, a second connecting plate is provided at the connection position between the flat plate and the corrugated plate. The inclination angle between the second connecting plate and the flat plate is greater than or equal to 45° and less than or equal to 135°.

[0013] Further, the first connecting plate and the second connecting plate are arranged at intervals, and the second connecting plate is connected to the flange.

[0014] Further, at least two second connecting plates are symmetrically arranged on both sides of the first connecting plate.

[0015] Further, the second connecting plate and the flange are arranged at intervals, and the first connecting plate is respectively connected to the second connecting plate and the flange.

[0016] Further, the first connecting plate and the second connecting plate are connected by a third connecting plate, and the second connecting plate, the third connecting plate and the flange are arranged at intervals.

[0017] Further, the connection node further includes a horizontal support, and the end of the horizontal support is connected to the third connecting plate.

[0018] Compared with the related art, the connection node provided by the present invention has the following beneficial effects:

[0019] 1. In the present invention, the web of the corrugated web roof beam is locally changed to a flat plate at the connection node, so that the moment of inertia of the cross-section at the node is contributed by both the flat plate and the flange. Therefore, the moment of inertia of the cross-section is larger in the direction parallel to the beam axis. When the roof beam bears the axial force of the tie rod, the bending resistance of the roof beam can be improved, and the bending deformation can be effectively resisted. Moreover, the first connecting plate connects the flat plate and the flange, and the tie rod is connected to the first connecting plate. This node structure form not only changes the tie rod connection method of the corrugated web beam in the related art, making it have universality and interchangeability with the tie rod connection method of the flat web beam, which is more conducive to the overall construction and maintenance of the building. Moreover, when bearing the axial force of the tie rod, the stress can be shared on the first connecting plate, the flat plate and the flange, which can effectively avoid cracks or damage caused by local stress concentration and improve the overall stability and reliability of the roof beam.

[0020] 2. In the present invention, the height of the flat plate is less than that of the corrugated plate. One end of the flat plate in the vertical direction is connected to the flange, and the other end is connected to the other flange through the corrugated plate, forming a combination of the flat plate and the corrugated plate not only in the axial direction of the beam, but also in the vertical direction. This is beneficial to adjusting the position of the connection points on the beam, enabling the beam to better bear the load and reducing the material consumption of the structure.

[0021] 3. In the present invention, a second connecting plate is provided at the connection position between the flat plate and the corrugated plate, and the inclination angle range between the second connecting plate and the flat plate is greater than or equal to 45° and less than or equal to 135°. The flat plate, the corrugated plate and the second connecting plate are connected to form an integral body, enabling the axial force of the supporting tie rod to be effectively transmitted to the roof beam and also playing a role in locally strengthening the corrugated web at the node.

[0022] 4. In the present invention, the first connecting plate and the second connecting plate are arranged at intervals, and the second connecting plate is connected to the flange, forming at least two spaced connection points between the flat plate and the flange, which can more evenly disperse the stress and effectively enhance the structural strength and stiffness of the roof beam.

[0023] 5. In the present invention, at least two second connecting plates are symmetrically arranged on both sides of the first connecting plate. Since the second connecting plate is located at the end of the flat plate, the first connecting plate and the second connecting plate together form a connection form of both ends and the middle on the flat plate, which is beneficial to enhancing the uniformity of the strength and rigidity of the node in the beam axis direction.

[0024] 6. In the present invention, the second connecting plate is arranged at intervals with the flange, and the first connecting plate is respectively connected to the second connecting plate and the flange, so that the second connecting plate, the flange and the first connecting plate form or are similar to form an I-shaped structure, greatly enhancing the structural strength and stiffness of the connection node.

[0025] 7. In the present invention, the third connecting plate is arranged at intervals between the horizontal connecting plate and the flange, and both ends of the third connecting plate in the extending direction of the beam body are connected to the vertical connecting plate and the first connecting plate, so that the horizontal support is closer to the upper flange to restrain the upper flange.

[0038] The embodiment of the present invention provides a connection node for a corrugated web roof beam, as Figure 1 shown in and Figure x, the connection node can be specifically applied to realize the connection between the corrugated web beam and other components of the roof support system. The connection node includes a beam body, a tie rod 7 and a first connecting plate 3, and the tie rod 7 is connected to the beam body through the first connecting plate 3; wherein, the web of the beam body is formed by connecting a flat plate 1 and a corrugated plate 2, the first connecting plate 3 connects the flat plate 1 and the flange 6 of the beam body, and the tie rod 7 is connected to the first connecting plate 3, and is used to directly transfer the axial force of the tie rod 7 to the flange 6 and the flat plate 1 through the first connecting plate 3, so as to share the normal stress of the roof beam.

[0041] In this embodiment, as Figure 1 shown, the end of the first connecting plate 3 protrudes from the flange 6 of the beam body, and the end of the tie rod 7 is connected to the protruding area of the first connecting plate 3. In the horizontal plane, the axial direction of the tie rod 7 is perpendicular to the axial direction of the beam body, and there is a certain inclination angle between the axial direction of the horizontal support 8 and the axial direction of the tie rod 7.

[0042] In this embodiment, as shown in Figure x, the beam body is in an I shape. When the beam body is connected to the tie rod 7, the web direction of the beam body is the vertical direction.

That is, the height of the flat plate 1 and the height of the corrugated plate 2 are both the distance between the two flanges 6 on both sides. Both the flat plate 1 and the corrugated plate 2 can independently connect to the surfaces of the two flanges 6 at both ends in the vertical direction. Corrugated plates 2 are respectively connected to both ends of the flat plate 1 in the extending direction of the beam body, forming a structural form in which the corrugated plate 2, the flat plate 1, and the corrugated plate 2 are connected in sequence.

[0046] In this embodiment, a second connecting plate 4 is provided at the connection position between the flat plate 1 and the corrugated plate 2, and the inclination angle between the second connecting plate 4 and the flat plate 1 is greater than or equal to 45° and less than or equal to 135°.

Not only are the two ends of the flat plate 1 respectively connected to the corrugated plate 2 in the extending direction of the beam body, forming a structural form in which the corrugated plate 2, the flat plate 1, and the corrugated plate 2 are connected in sequence, but also in the vertical direction, a structural form in which the flange 6, the flat plate 1, the corrugated plate 2, and the flange 6 are connected in sequence is formed.
