In the description of the present application, unless otherwise indicated, the meaning of "a plurality" is two or more.

In the description of the present application, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be either fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present application will be understood in specific cases by those of ordinary skill in the art.

Referring to fig. 1 to 4, fig. 1 and 2 show cross-sectional structures of an i-shaped tube and a cross-shaped tube, respectively. In the process of building construction, steel pipes 100 with wing plates with different cross sections need to be butted, for example, the cross-shaped steel pipe 100 with the wing plates is butted with a round pipe 201, and the cross-shaped steel pipe 100 with the wing plates can meet the ventilation requirement in the force performance or the concrete pouring process, so that the design target is met. However, since the cross-shaped steel pipe 100 having the flanges generally has the planar flanges 20, when the steel pipe 100 having the flanges is butted against the round pipe 201 at the end portion, the planar flanges 20 are difficult to adapt to the curvature of the round pipe 201 (as shown in fig. 3), and therefore, the butt joint of the cross-shaped steel pipe 100 having the flanges and the round pipe 201 is difficult to achieve. In the related art, when the steel pipe 100 with the cross-shaped wing plate is in butt joint with the round pipe 201, a transition piece is usually required to be additionally arranged, one end of the transition piece is connected with the cross-shaped pipe, the other end of the transition piece is connected with the round pipe 201, the transition piece is used for gradually transiting the flat-shaped wing plate 20 to adapt to the curvature of the round pipe 201, and the problems of complex process, difficult implementation and the like caused by arranging the transition piece are caused.

In view of this, the present application provides a steel pipe 100 with flanges, which can facilitate the butt joint of the steel pipe 100 with flanges directly with a round pipe 201. Referring to fig. 5 to 6 and 8 to 10, a steel pipe 100 having flanges includes a plurality of webs 10 and a plurality of flanges 20, and the number of flanges 20 is set to be the same as the number of webs 10. One of the long sides of the web 10 is connected to each other and forms a center O, and the other long side is spaced circumferentially around the center O. The wing plate 20 is provided on the other side of the web 10, and the wing plate 20 is provided to be curved toward the center O. By adopting the scheme, on one hand, the bent wing plate 20 can be well adapted to the curvature of the circular tube 201, the arc-shaped wing plate 20 and the circular tube 201 can be directly connected at the end part, for example, can be directly welded, and a transition piece is not required to be additionally arranged for the steel tube 100 with the wing plate, so that the plane of the wing plate 20 is adapted to the curvature of the circular tube 201. On the other hand, the wing plates 20 provided to be bent toward the web 10 are advantageous in increasing the contact area of the end surfaces of the wing plates 20 with the end surfaces of the round tube 201, thereby making it easy for the steel tube 100 having the wing plates to be butted with the round tube 201, and improving the strength and stability of the connection therebetween. By adopting the scheme of the application, two steel pipes 100 with wing plates with different cross-sectional shapes can be conveniently butted, the connection between the I-shaped pipe or the cross-shaped pipe with the wing plates 20 and the round pipe 201 is realized, the construction process is simplified and the implementation efficiency is improved on the premise of ensuring the connection strength.

Referring to fig. 5 to 6, it can be understood that for the cross-shaped tube (as shown in fig. 5), there are four webs 10 and four corresponding wing plates 20, and the four wing plates 20 are disposed on the long sides of the outer periphery of the web 10. Of course, two webs 10 of the four webs 10 may be disposed in a coplanar manner, and the two planes may be perpendicular to each other or form an acute or obtuse included angle. Of course, in other examples, the number of webs 10 may also be provided as 3 pieces, 5 pieces, etc. For example, a steel pipe 100 with flanges as shown in fig. 6 is provided with 3 webs 10, and correspondingly, the number of flanges 20 is set to 3. Preferably, 3 webs 10 are equally spaced circumferentially about the center. The steel pipe 100 having the flanges mentioned below will be described by taking a cross-shaped pipe as an example.

In some embodiments, the plurality of wings 20 are curved along the same circular arc trajectory, and the plurality of wings 20 have the same arc length. The curvature of each wing plate 20 is the same, and the same round shape can be formed, when the steel pipe 100 with the wing plates is connected with the circular pipe 201, the end parts of the wing plates 20 can be correspondingly connected with the end parts of the circular pipe 201, so that the connection area of the two pipes in butt joint is increased, and the connection strength and stability are improved. Further, by providing each wing plate 20 with the same arc length, the interaction force between the wing plates and the round pipe 201 can be uniformly distributed when the wing plates are butted with the round pipe 201, and the butting accuracy and the connecting stability can be improved.

In some embodiments, the wings 20 are circumferentially spaced apart. That is, although the wings 20 of the cross-shaped tube are provided in an arc shape, the edges of the respective wings 20 are not connected to each other. That is, gaps are also left between edges of two adjacent wing plates 20 of the cross-shaped pipe, so that it can be ensured that the arc-shaped wing plates 20 do not affect the original performance of the steel pipe, for example, when the cross-shaped pipe is subjected to concrete pouring, gaps are left between the adjacent wing plates 20, and ventilation and solidification of concrete can be ensured.

In some embodiments, the steel pipe 100 with the flanges may also be configured to have an i-shaped cross-section. Specifically, the device comprises a web plate 10 and two wing plates 20, wherein the wing plates 20 are respectively arranged on two long sides of the web plate 10, and the wing plates 20 are arc-shaped and bend towards the web plate 10. Similarly, the I-shaped steel with the arc-shaped wing plates 20 is beneficial to butt joint with the circular tube 201, and the butt joint efficiency and the connection strength of the I-shaped steel and the circular tube 201 are improved. The beneficial effects of the butt joint of the i-section steel and the round pipe 201 are similar to those of the cross section steel, and the description of the cross section steel is already provided in the foregoing, and will not be repeated here.

In some embodiments, each of the flanges 20 of the i-section steel may be configured to have the same arc length, with the flanges 20 being symmetrically disposed with respect to the web 10. For example, the two flanges 20 of the i-shaped pipe are axially symmetrically arranged with respect to the vertical line of the web 10, so that the steel pipe 100 having the flanges has symmetry, has a simple structure, and can simplify the operations of manufacturing, mounting, use, and the like. Similarly, in other examples, four wings 20 of the cross-shaped tube may be disposed axisymmetrically with respect to web 10 or centrally with respect to the midpoint of web 10, again providing ease of manufacture, installation and use.

In some embodiments, the curvature of wing 20 is formed by bending. Wing panel 20 can be bent to the desired curvature, for example, using a hydraulic press and cooperating with a die. This can simplify the manufacturing process of the steel pipe, and can obtain the steel pipe having the arc-shaped wing plate 20 without changing the original manufacturing process.

In some embodiments, referring to fig. 9, along the extending direction of the steel tube 100 with the flanges, the web 10 is further provided with a plug portion 111 protruding from the end of the flange 20, and the plug portion 111 is used to extend into the circular tube 201 when being docked with the circular tube 201. That is, at the end of the steel pipe, the web 10 extends at least a certain length beyond the wing plate 20. Thus, when the steel pipe 100 with the wing plates is in butt joint with the round pipe 201, the plug-in part 111 can extend into the round pipe 201, on one hand, the butt joint between the round pipe 201 and the steel pipe 100 with the wing plates can be facilitated, and when the two pipes are not welded and fixed, the web 10 extending into the round pipe 201 can provide a certain supporting connection effect so as to facilitate the subsequent welding connection of the two pipes. On the other hand, the web 10 extending into the circular tube 201 can increase the area of connection of two tubes, that is, in addition to the welded connection at the ends, connection can also be achieved inside the tubes by the web 10, thereby improving the strength and stability of the connection.

In some embodiments, along the extending direction of the steel pipe 100 with the wing plate, the steel pipe 100 with the wing plate comprises a plane section, a transition section and an arc section which are sequentially connected, the wing plate 20 is in a flat plate shape in the plane section, the wing plate 20 is in an arc shape in the arc section, the transition section is located between the plane section and the arc section, so that the wing plate 20 is transited from the flat plate shape to the arc shape, and the arc section is used for being connected with the round pipe 201. That is, in the steel pipe 100 having the flanges, different sections are divided in the length direction thereof, and the flanges 20 take different shapes in the different sections. The flat-plate-shaped wing plates 20 can be gradually transitionally connected to an arc-shaped state by using the transition section. In this way, when the arc section is connected to the circular tube 201, the effect of directly connecting the arc wing plate 20 to the end of the circular tube 201 can be achieved, and the wing plate 20 can still maintain the flat plate structure in the plane section.

The arc shape presented by the wing plate 20 at the arc section and the transition section can be formed by bending the wing plate with the cooperation of the hydraulic press and the die, so that the steel pipe 100 with the wing plate has the transition section and the arc section without additionally welding the transition piece to be connected with the round pipe 201, on one hand, the construction process can be simplified, the welding operation is reduced, on the other hand, the transition section and the arc section are different sections on the same steel pipe, and therefore, the steel pipe does not need to be connected with other transition pieces, thereby the steel pipe can have higher strength.

The present application also provides a steel pipe butt joint structure 200 with flanges, referring to fig. 8 to 10, wherein the steel pipe butt joint structure 200 with flanges comprises a round pipe 201 and the steel pipe 100 with flanges (which may be cross-shaped steel or i-shaped steel, etc.), the round pipe 201 is connected with the end of the steel pipe 100 with flanges, the curvature of the flanges 20 of the steel pipe 100 with flanges is the same as the curvature of the round pipe 201, and the flanges 20 are used for connecting with the round pipe 201 when the round pipe 201 is connected with the end of the steel pipe 100 with flanges. By setting the curvature of the wing plate 20 to be the same as that of the round tube 201, when two tubes are connected, the end of the wing plate 20 and the end of the round tube 201 can be completely and correspondingly attached, so that the accuracy of alignment connection of the two tubes is improved, connection of the two tubes with different cross-sectional shapes is realized, and the connection strength of the steel tube 100 with the wing plate and the round tube 201 is ensured.

Alternatively, the round tube 201 is welded to the steel tube 100 with the flanges. The welding can provide sufficient strength of connection between the two pipes.

In some embodiments, along the extending direction of the steel pipe 100 with the flanges, the web 10 is provided with a plug-in part 111 protruding from the end of the flange 20, and when the round pipe 201 is connected with the end of the steel pipe 100 with the flanges, the plug-in part 111 extends into the round pipe 201 and makes the end of the flange 20 abut against the end of the round pipe 201. Thus, when the steel pipe 100 with the wing plates is in butt joint with the round pipe 201, the plug-in part 111 can extend into the round pipe 201, on one hand, the butt joint between the round pipe 201 and the steel pipe 100 with the wing plates can be facilitated, and when the two pipes are not welded and fixed, the web 10 extending into the round pipe 201 can provide a certain supporting connection effect so as to facilitate the subsequent welding connection of the two pipes. On the other hand, the web 10 extending into the circular tube 201 can increase the area of connection of two tubes, that is, in addition to the welded connection at the ends, connection can also be achieved inside the tubes by the web 10, thereby improving the strength and stability of the connection.

In some embodiments, the steel pipe butt joint structure 200 may also provide filler 202, such as poured concrete, in the steel pipe 100 with the flanges. The steel pipe 100 with flanges has a space between the web 10 and the flanges 20, which can be used for casting concrete, thereby further improving the strength of the steel pipe 100 with flanges. Of course, concrete can also be poured into the interior of the tubular 201, thereby increasing the strength of the overall steel pipe butt joint structure 200.
