Description

Technical Field

[0001] This application relates to the field of hot-rolled steel technology, and in particular to an H-beam and its processing method. Background Technology

[0002] H-beams are an economical and efficient profile with a more optimized cross-sectional area distribution and a more reasonable strength-to-weight ratio. They are named for their cross-section resembling the letter "H". Because all parts of an H-beam are arranged at right angles, it has advantages such as strong bending resistance in all directions, simple construction, cost savings, and light structural weight, and has been widely used.

[0003] The existing Chinese patent with authorization announcement number CN204435666U provides an H-beam, which includes an upper flange and a lower flange that are parallel to each other, and a web connecting the upper flange and the lower flange. When erecting a building, the H-beam is used as a supporting beam. The web is set vertically to bear the large weight of the reinforced concrete. The two ends of the lower flange are fixed to the building. The lower flange and the web form a "T" shape structure, which better plays the role of load bearing. The upper flange is mainly used for reinforced concrete pouring.

[0004] The aforementioned technologies have the following drawbacks: Since concrete is a non-homogeneous material, when H-beams are used, cracks are prone to appear at the interface between the steel beam and the concrete. Under load, these cracks will spread randomly, thereby affecting the strength of the entire H-beam concrete structure and consequently the safety performance of the building. Summary of the Invention

[0005] To improve the structural strength of H-beams, this application provides an H-beam and a method for processing it.

[0006] The first objective of this application provides an H-beam, which adopts the following technical solution:

[0007] An H-beam includes an upper flange, a web, and a lower flange. The two sides of the web in the width direction are located between the upper flange and the lower flange. A support plate is provided between the upper flange and the lower flange. A positioning rod is provided on the web. A positioning hole is provided on the support plate to be inserted into the positioning rod. A fixing component is provided on the support plate to restrict the positioning rod within the positioning hole.

[0008] By adopting the above technical solution, when the H-beam is transported, the support plate is removed from the web, thus not affecting the normal transportation of the H-beam; when the H-beam is installed on a building, the positioning holes of the support plate are fitted onto the positioning rod, making the support plate perpendicular to the web; and the positioning rod is restricted in the positioning hole by the fixing component, thereby fixing the support plate. When the upper and lower flanges bear the weight of reinforced concrete, the two ends of the support plate abut against the sides of the upper and lower flanges respectively, thereby effectively reducing the deformation of the H-beam and improving the structural strength of the H-beam.

[0009] Optionally, the fixing component includes a connecting hole and a fixing rod slidably connected in the connecting hole. The connecting hole is opened on the side of the support plate, and the connecting hole and the positioning hole are respectively located on adjacent sides of the support plate. The side of the positioning rod is provided with a fixing groove that is inserted into the end of the fixing rod. A return spring is sleeved on the fixing rod. One end of the return spring is fixed to the fixing rod, and the other end is fixed to the wall of the connecting hole.

[0010] By adopting the above technical solution, an external force is applied to the fixing rod, causing the end of the fixing rod to be inserted into the fixing groove, thereby confining the positioning rod within the positioning hole and achieving the purpose of fixing the support plate; the return spring allows the end of the fixing rod to be located within the connecting hole, reducing the impact of the presence of the fixing rod on the insertion of the positioning rod into the positioning hole. The structure is simple and the installation is quick.

[0011] Optionally, both the upper flange and the lower flange are threaded with abutting members. The abutting members include a first screw and a first protrusion. The first protrusion is fixedly connected to the first screw, and the connecting hole is inserted into the end of the first screw away from the first protrusion.

[0012] By adopting the above technical solution, when the connecting hole is aligned with the first screw, screwing the first protrusion causes the first screw to screw into the upper or lower flange, allowing the end of the first screw to be inserted into the connecting hole, thereby resisting the movement of the fixing rod within the connecting hole, achieving the purpose of inserting the end of the fixing rod away from the first screw into the fixing groove; at the same time, the first screw can connect the support plate and the upper flange, and the support plate and the lower flange, thus making the support plate more stable on the H-beam; the first protrusion protrudes from the surface of the upper or lower flange, giving the H-beam the effects of anti-slip, sound insulation and impact load reduction.

[0013] Optionally, the wall of the connecting hole is provided with an internal thread that mates with the thread of the first screw.

[0014] By adopting the above technical solution, the first screw and the internal thread are matched, which improves the connection strength between the support plate and the upper flange, and between the support plate and the lower flange, and reduces the outward deformation of the upper flange and the lower flange.

[0015] Optionally, the length of the positioning rod is half the length of the support plate, and the distance between the positioning rod and the upper flange is the same as the distance between the positioning rod and the lower flange.

[0016] By adopting the above technical solution, the length and position of the positioning rod are set to reduce the deformation caused by uneven stress on the support plate, so that the support plate can better mitigate the impact load.

[0017] Optionally, the fixing component includes a threaded hole and a second screw threaded into the threaded hole. The threaded hole is located on the side of the support plate, and the threaded hole and the positioning hole are located on opposite sides of the support plate. The end of the positioning rod is hinged to a locking rod that can abut against the second screw. The support plate has a locking cavity that engages with the locking rod. The locking cavity is connected to the positioning hole. The end face of the locking rod facing the second screw is an inclined surface.

[0018] By adopting the above technical solution, the second screw is turned so that it moves in the threaded hole. The end of the second screw will push the inclined surface of the snap-fit ​​rod, so that the free end of the snap-fit ​​rod is inserted into the snap-fit ​​cavity, thereby achieving the purpose of fixing the support plate. The structure is simple.

[0019] Optionally, a T-shaped snap-fit ​​block is fixedly connected to the support plate, and snap-fit ​​grooves that engage with the snap-fit ​​block are provided on both the upper flange and the lower flange.

[0020] By adopting the above technical solution, the snap-fit ​​block and snap-fit ​​groove can be used to connect and fix the support plate to the upper flange and the support plate to the lower flange, so that the support plate is more stable on the H-beam.

[0021] Optionally, the connection points formed by the upper flange and the lower flange and the web are smoothly transitioned.

[0022] By adopting the above technical solutions, the bonding tightness between H-beams and concrete can be improved, thereby increasing the stiffness and load-bearing capacity of the entire H-beam concrete structure, as well as its seismic performance.

[0023] Optionally, a second protrusion is fixedly connected to the surfaces of both the upper flange and the lower flange.

[0024] By adopting the above technical solution, the second protrusion increases the contact area between the H-beam and the concrete, thereby allowing the H-beam and the concrete to solidify better; at the same time, the second protrusion protrudes from the surface of the upper or lower flange, which allows the H-beam to have the effects of anti-slip, sound insulation and shock load reduction.

[0025] Another objective of this application is to provide a method for processing H-beams, which adopts the following technical solution:

[0026] A method for processing H-beams includes the following steps:

[0027] The components of the H-beam, namely the upper flange, lower flange, and web, are hot-rolled.

[0028] Weld a fixed positioning rod to the side of the web;

[0029] Select a support plate that is compatible with the H-beam, and make positioning holes on the side of the support plate to fit the positioning rod.

[0030] A fixing component is provided on the support plate to confine the positioning rod within the positioning hole.

[0031] By adopting the above technical solution, when the H-beam is being transported, the support plate can be removed from the web, thus not affecting the normal transportation of the H-beam; when the H-beam is installed on a building, the positioning holes of the support plate are fitted onto the positioning rod, making the support plate perpendicular to the web; and the positioning rod is restricted in the positioning hole by the fixing component, thereby fixing the support plate. When the upper and lower flanges bear the weight of reinforced concrete, the two ends of the support plate abut against the sides of the upper and lower flanges respectively, thereby effectively reducing the deformation of the H-beam and improving the structural strength of the H-beam.

[0032] In summary, this application includes at least one of the following beneficial technical effects:

[0033] 1. When transporting H-beams, the support plate is removed from the web to ensure uninterrupted transport. When the H-beams are installed on buildings, the positioning holes of the support plate are fitted onto the positioning rods, making the support plate perpendicular to the web. The positioning rods are then secured within the positioning holes using a fixing assembly, thus fixing the support plate. When the upper and lower flanges bear the weight of reinforced concrete, the two ends of the support plate abut against the sides of the upper and lower flanges, respectively, effectively reducing the deformation of the H-beams and improving their structural strength.

[0034] 2. When the connecting hole is aligned with the first screw, screwing the first protrusion causes the first screw to screw into the upper or lower flange, allowing the end of the first screw to be inserted into the connecting hole, thereby resisting the movement of the fixing rod within the connecting hole. This achieves the purpose of inserting the end of the fixing rod away from the first screw into the fixing groove. At the same time, the first screw can connect the support plate to the upper flange and the support plate to the lower flange, thus making the support plate more stable on the H-beam. The first protrusion protrudes from the surface of the upper or lower flange, giving the H-beam anti-slip, sound insulation, and impact load reduction effects. Attached Figure Description

[0040] To make the purpose, technical solution, and advantages of this application clearer, the following description is provided in conjunction with the appendix. Figure 1-4 The present application will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the application.

[0041] This application discloses an H-beam.

[0042] Example 1: Refer to Figure 1 and Figure 2 The H-beam includes an upper flange 1, a web 2, and a lower flange 3. The two sides of the web 2 in the width direction are located between the upper flange 1 and the lower flange 3. The web 2, upper flange 1, and lower flange 3 are formed by hot rolling in one piece, and their cross-sections are all rectangular. In other embodiments, the upper flange 1 and lower flange 3 may be made of steel thicker in the middle than at the sides. The connections between the upper flange 1 and lower flange 3 and the web 2 are smooth, which improves the bonding tightness between the H-beam and the concrete, thereby increasing the stiffness and load-bearing capacity of the entire H-beam concrete structure, and also improving its seismic performance.

[0043] Reference Figure 1 and Figure 2To improve the bonding tightness between the H-beam and the concrete, second protrusions 12 are fixedly connected to the surfaces of both the upper flange 1 and the lower flange 3. Multiple second protrusions 12 are located on the surfaces of the upper flange 1 and the lower flange 3 away from the web 2, arranged in an array. The row direction of each row in the array is aligned with the length direction of the upper flange 1 or the lower flange 3, and the column direction of each column is aligned with the width direction of the upper flange 1 or the lower flange 3. Furthermore, the second protrusions 12 are hot-rolled to form connections with the upper flange 1 and the lower flange 3. The connection between the side of the second protrusion 12 and the outer side of the upper flange 1 or the lower flange 3 forms a smooth curve transition. The cross-section of the second protrusion 12 is polygonal; in this application, a rectangle is used, but in other embodiments, a rhombus shape may also be used.

[0044] Reference Figure 1 and Figure 2 To facilitate the installation of the H-beam, mounting holes 13 are provided at both ends of the web 2. The mounting holes 13 are circular, and the connection between the mounting holes 13 and the web 2 is a smooth curve transition. In other embodiments, the shape of the mounting holes 13 can be adjusted according to the actual situation. The H-beam can be fixed to the steel column or other steel sections by using the mounting holes 13 and bolts.

[0045] Reference Figure 1 and Figure 2 To increase the structural strength of the H-beam, a support plate 4 is installed between the upper flange 1 and the lower flange 3, and a positioning rod 5 is fixed on the web 2. The support plate 4 has positioning holes 6 that engage with the positioning rod 5. Two support plates 4 are installed at each end of the H-beam, positioned opposite each other on the web 2. The dimensions of the support plates 4 are adapted to the H-beam. When the positioning rod 5 is inserted into the positioning hole 6, the side of the support plate 4 closest to the web 2 is in contact with the side of the web 2, the upper surface of the support plate 4 is in contact with the lower surface of the upper flange 1, the lower surface of the support plate 4 is in contact with the upper surface of the lower flange 3, and the side of the support plate 4 furthest from the web 2 can be aligned with the sides of the upper flange 1 and the lower flange 3.

[0046] Reference Figure 1 and Figure 2To facilitate insertion of the positioning rod 5 into the positioning hole 6, the positioning rod 5 is a round rod, and the end of the positioning rod 5 away from the web plate 2 is rounded. The length of the positioning rod 5 is half the length of the support plate 4, and the distance between the positioning rod 5 and the upper flange 1 is the same as the distance between the positioning rod 5 and the lower flange 3. The positioning rod 5 is fixed to the side of the web plate 2 by welding. In other embodiments, the web plate 2, upper flange 1, lower flange 3, second protrusion 12, and positioning rod 5 can be formed by hot rolling in one piece. By adjusting the length and position of the positioning rod 5, the uneven stress on the support plate 4 and the resulting deformation are reduced, allowing the support plate 4 to better mitigate impact loads.

[0047] Reference Figure 1 and Figure 2 To reduce the separation of the positioning rod 5 from the support plate 4, the support plate 4 is provided with a fixing component 7 for confining the positioning rod 5 within the positioning hole 6. The fixing component 7 includes a connecting hole 71 and a fixing rod 72 slidably connected within the connecting hole 71. The connecting hole 71 is located on the side of the support plate 4. The side of the positioning rod 5 is provided with a fixing groove 73 that engages with the end of the fixing rod 72. A return spring 74 is sleeved on the fixing rod 72. One end of the return spring 74 is fixed to the fixing rod 72, and the other end is fixed to the wall of the connecting hole 71.

[0048] It should be noted that the positioning hole 6 is located on the side of the support plate 4 facing the web plate 2. Each support plate 4 has two connecting holes 71, one of which is located on the side of the support plate 4 facing the upper flange 1, and the other is located on the side of the support plate 4 facing the lower flange 3. That is, the connecting hole 71 and the positioning hole 6 are located on adjacent sides of the support plate 4. The two ends of the return spring 74 are fixed to the wall of the fixing rod 72 and the connecting hole 71 by welding, respectively. The diameter of the connecting hole 71 at the return spring 74 is larger than the diameter of the two ends of the connecting hole 71. By applying external force to the fixing rod 72, the end of the fixing rod 72 is inserted into the fixing groove 73, thereby confining the positioning rod 5 within the positioning hole 6, achieving the purpose of fixing the support plate 4. The return spring 74 allows the end of the fixing rod 72 to be located within the connecting hole 71, reducing the impact of the presence of the fixing rod 72 on the insertion of the positioning rod 5 into the positioning hole 6.

[0049] Reference Figure 1 and Figure 2To apply external force to the fixing rod 72, both the upper flange 1 and the lower flange 3 are threadedly connected to abutment members 8. Abutment member 8 includes a first screw 81 and a first protrusion 82. The first protrusion 82 is fixedly connected to the first screw 81, and the connecting hole 71 is inserted into the end of the first screw 81 away from the first protrusion 82. The first protrusion 82 and the first screw 81 are integrally formed. The connection between the side of the first protrusion 82 and the first screw 81 forms a smooth curve transition. The cross-section of the first protrusion 82 is polygonal; in this application, a rectangle is used, but in other embodiments, a rhombus shape may also be used.

[0050] It should be noted that when the connecting hole 71 is aligned with the first screw 81, the first protrusion 82 is screwed in so that the first screw 81 is screwed into the upper flange 1 or lower flange 3, so that the surface of the first protrusion 82 facing the first screw 81 abuts against the surface of the upper flange 1 or lower flange 3. At the same time, the end of the first screw 81 is inserted into the connecting hole 71, thereby abutting the fixing rod 72 and moving it within the connecting hole 71, thus achieving the purpose of inserting the end of the fixing rod 72 away from the first screw 81 into the fixing groove 73. The first screw 81 can connect the support plate 4 and the upper flange 1, and the support plate 4 and the lower flange 3, reducing the rotation of the support plate 4 around the positioning rod 5 as the axis, thereby making the support plate 4 more stable on the H-beam. The first protrusion 82 protrudes from the surface of the upper flange 1 or lower flange 3, which can give the H-beam the effects of anti-slip, sound insulation and shock load reduction.

[0051] Reference Figure 1 and Figure 2 To improve the connection strength between the support plate 4 and the H-beam, an internal thread 9 is integrally formed on the wall of the connecting hole 71. The internal thread 9 is located on the wall of the connecting hole 71 at the end furthest from the positioning hole 6, and it engages with the first screw 81. The engagement of the first screw 81 with the internal thread 9 improves the connection strength between the support plate 4 and the upper flange 1, and between the support plate 4 and the lower flange 3, reducing outward deformation of the upper flange 1 and the lower flange 3.

[0052] Example 2: Refer to Figure 3 and Figure 4 The difference between this embodiment and Embodiment 1 is that the fixing component 7 includes a threaded hole 75 and a second screw 76 threadedly connected within the threaded hole 75. The threaded hole 75 is located on the side of the support plate 4. The positioning hole 6 is located on the side of the support plate 4 facing the web plate 2, while the threaded hole 75 is located on the side of the support plate 4 away from the web plate 2; that is, the threaded hole 75 and the positioning hole 6 are located on opposite sides of the support plate 4. Furthermore, the threaded hole 75 and the positioning hole 6 are connected.

[0053] Reference Figure 3 and Figure 4To reduce the separation of the positioning rod 5 from the support plate 4, a locking rod 77 is hinged to the end of the positioning rod 5. Each positioning rod 5 has two locking rods 77. A locking cavity 78 is provided inside the support plate 4, communicating with the positioning hole 6, and engaging with the locking rod 77. The end faces of both locking rods 77 facing the second screw 76 are inclined surfaces, and the second screw 76 abuts against the inclined surfaces of the locking rods 77; that is, the free ends of the two locking rods 77 have opposing inclined surfaces. In other embodiments, the end of the second screw 76 facing the locking rod 77 is truncated cone-shaped.

[0054] It should be noted that by screwing the second screw 76 into the threaded hole 75, the end of the second screw 76 pushes the inclined surface of the snap-fit ​​rod 77, thereby inserting the free end of the snap-fit ​​rod 77 into the snap-fit ​​cavity 78, thus achieving the purpose of fixing the support plate 4. The structure is simple.

[0055] Reference Figure 3 and Figure 4 To improve the connection strength between the support plate 4 and the H-beam, a snap-fit ​​block 10 is fixedly connected to the support plate 4. Snap-fit ​​grooves 11 are provided on both the upper flange 1 and the lower flange 3 to engage with the snap-fit ​​block 10. The snap-fit ​​block 10 has a T-shaped cross-section and is integrally formed with the support plate 4. There are two snap-fit ​​blocks 10: one located on the side of the support plate 4 facing the upper flange 1, and the other located on the side of the support plate 4 facing the lower flange 3. In other embodiments, the snap-fit ​​block 10 may also have an L-shaped cross-section. By engaging the snap-fit ​​block 10 with the snap-fit ​​groove 11, the support plate 4 can be connected and fixed to the upper flange 1 and the lower flange 3, thus making the support plate 4 more stable on the H-beam.

[0056] The implementation principle of an H-beam according to an embodiment of this application is as follows: When the H-beam is being transported, the support plate 4 is removed from the web plate 2, thus not affecting the normal transportation of the H-beam; when the H-beam is installed on a building, the positioning hole 6 of the support plate 4 is fitted onto the positioning rod 5, so that the support plate 4 is perpendicular to the web plate 2; and the positioning rod 5 is restricted in the positioning hole 6 by the cooperation of the fixing rod 72 and the fixing groove 73, thereby fixing the support plate 4. When the upper flange 1 and the lower flange 3 bear the weight of reinforced concrete, the two ends of the support plate 4 abut against the sides of the upper flange 1 and the lower flange 3 respectively, thereby effectively reducing the deformation of the H-beam and improving the structural strength of the H-beam.

[0057] This application also discloses a method for processing H-beams, including the following steps:

[0058] Step S1: The upper flange 1, lower flange 3 and web 2 of the H-beam are hot rolled into shape.

[0059] Step S2: Positioning rods 5 are welded and fixed on both sides of the web plate 2.

[0060] Step S3: Select a support plate 4 that is compatible with the H-beam, and open a positioning hole 6 on the side of the support plate 4 to engage with the positioning rod 5.

[0061] Step S4: A fixing component 7 for confining the positioning rod 5 within the positioning hole 6 is installed on the support plate 4.

[0062] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Any feature disclosed in this specification (including the abstract and drawings) may be replaced by other equivalent or similar features unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is only one example of a series of equivalent or similar features.
