Description

Technical Field

[0001] The present application relates to the field of steel sections, and in particular to an H-shaped steel section. Background Art

[0002] H-shaped steel is a kind of profile. It has the advantages of strong bending resistance, simple construction, cost saving and light structure weight, and has been widely used. The crossbeams in the factory are generally made of H-shaped steel. Two adjacent H-shaped steels with the same length are usually fixed to the columns by bolts and nuts.

[0003] When the roof of the factory building shakes under the action of wind, the shaking of the roof will cause the H-shaped steel and the column to move relative to each other, resulting in the misalignment of the two adjacent H-shaped steels. The misalignment of the H-shaped steel will cause the supporting position of the H-shaped steel on the roof to change, reducing the supporting effect of the H-shaped steel on the roof. Summary of the invention

[0004] In order to maintain the supporting effect of the H-shaped steel on the roof, the present application provides an H-shaped steel.

[0005] The H-beam provided in this application adopts the following technical solution:

[0006] An H-shaped steel comprises a web and flanges perpendicular to the web fixedly connected on the upper and lower surfaces of the web, two fixing plates are provided at one end between the two flanges, the web is located between the two fixing plates, a plug-in hole is formed between the fixing plate and the web, a plug-in plate corresponding to the plug-in hole is fixedly connected to the other end between the two flanges, a mounting groove is provided on the side wall of the plug-in plate close to the fixing plate, the mounting groove is located outside the H-shaped steel, a fixing block that moves along the width direction of the H-shaped steel is slidably plugged into the mounting groove, a fixing hole corresponding to the fixing block is provided on the fixing plate, and a rotating component that drives the fixing block to rotate to be misaligned with the fixing hole is also provided at one end of the H-shaped steel connected to the fixing plate, and the number of rotating components corresponds to the number of fixing blocks.

[0007] By adopting the above technical solution, when the operator needs to fix two H-shaped steels with the same length direction, first align the plug-in plate with the plug-in hole, then push the plug-in plate into the plug-in hole, and when the fixing block is close to the fixing plate, push the fixing block into the installation groove, and continue to push the plug-in plate until the fixing block is located in the plug-in hole; when the fixing block moves to align with the fixing hole, move the fixing block outside the plug-in hole until the fixing block moves to the side of the fixing plate away from the web, and at this time, the rotating assembly works to push the fixing block to rotate, so that the fixing block is misaligned with the fixing hole, and finally the operator uses bolts and nuts to fix the H-shaped steel to the column, and at this time, the fixing block cooperates with the fixing hole to fix the two H-shaped steels, thereby reducing the relative movement of the two H-shaped steels with the same length direction along their own width direction, and maintaining the supporting effect of the H-shaped steel on the roof.

[0008] Optionally, a guide rod with a rectangular cross-section is provided in the installation groove, the guide rod is slidably plugged into the plug-in plate, the fixed block is rotatably connected to the guide rod, a connecting spring is sleeved on the guide rod, one end of the connecting spring is fixedly connected to the bottom wall of the installation groove, and the other end of the connecting spring abuts against the fixed block.

[0009] By adopting the above technical solution, in the initial state, the connecting spring is in a natural state, and the fixed block is located outside the installation groove as a whole. When the fixed block moves to contact with the fixed plate, the operator presses the fixed block into the installation groove, and the movement of the fixed block drives the guide rod to move, and at the same time the fixed block compresses the connecting spring; when the fixed block is located in the plug-in hole, the operator pushes the plug-in plate, and when the fixed block is aligned with the fixed hole, the connecting spring restores its deformation and pushes the fixed block to move outside the plug-in hole. When the connecting spring returns to its natural state, the fixed block is located on the side of the fixed plate away from the web.

[0010] Optionally, the rotating assembly includes a driving member for driving the fixed block to rotate and a control member for controlling the operation of the driving member.

[0011] By adopting the above technical solution, when the fixing block moves to the side of the fixing plate away from the web, the fixing block triggers the control member to work, the control member controls the driving member to work, and the driving member drives the fixing block to rotate to be misaligned with the fixing hole.

[0012] Optionally, the driving member is located on the side of the fixed plate away from the web, and the driving member includes a driving plate slidably connected to the lower surface of the upper flange, the driving plate slides along the length direction of the H-beam, a driving spring is fixedly connected to the driving plate, and one end of the driving spring away from the driving plate is fixedly connected to the side of the fixing hole away from the end face of the H-beam, and the control member limits the driving plate.

[0013] By adopting the above technical solution, in the initial state, the control component makes the drive plate located on the side of the fixing hole away from the end face of the H-shaped steel, and the driving spring is in a compressed state. When the fixed block moves to the side of the fixing plate away from the web, the fixed block triggers the control component to work. At this time, the control component releases the limit on the drive plate, and the driving spring restores its deformation and pushes the drive plate to move. The movement of the driving plate pushes the fixed block to rotate, thereby causing the fixed block to be misaligned with the fixing hole.

[0014] Optionally, the control member is located on the side of the fixed plate away from the web, and the control member includes a pressure plate slidably connected to the upper surface of the lower flange, and a plurality of clamping springs are fixedly connected to the side wall of the pressure plate away from the fixed plate, the pressure plate is located on the side of the driving plate close to the end face of the H-beam, and the side wall of the pressure plate close to the driving plate is located on the side of the fixing hole away from the end face of the H-beam.

[0015] By adopting the above technical solution, the pressure plate limits the driving plate. When the fixed block moves out of the plug-in hole, the fixed block pushes the pressure plate to move away from the fixed plate. When the fixed block is located as a whole on the side of the fixed plate away from the belly plate, the pressure plate releases the limit on the driving plate. At this time, the driving plate can push the fixed block to rotate under the action of the driving spring.

[0016] Optionally, the pressing plate abuts against the fixing plate.

[0017] By adopting the above technical solution, when the fixed block moves to the side of the fixed plate away from the web, the pressure plate abuts against the fixed block, thereby reducing the situation where the fixed block rotates automatically under the action of its own gravity.

[0018] Optionally, the side wall of the fixing block away from the guide rod is inclined, and the inclined side wall of the fixing block gradually inclines in a direction away from the guide rod from a side away from the end face of the H-beam to a side close to the end face of the H-beam.

[0019] By adopting the above technical solution, during the process of the operator delivering the plug board to the plug hole, when the fixed block moves to a position close to the fixed plate, the operator pushes the fixed block into the installation slot and continues to push the plug board until the inclined side wall of the fixed block contacts the fixed plate. At this time, the operator can release the fixed block and continue to push the plug board. The movement of the plug board drives the fixed block to move. During the movement of the fixed block, the fixed plate pushes the fixed block to move into the installation slot, which reduces the situation where the operator needs to push the fixed block as a whole into the installation slot before continuing to push the plug board, so that the operator can more conveniently insert the plug board into the plug hole.

[0020] Optionally, a screw rod is fixedly connected to the end surface of the guide rod away from the bottom wall of the installation groove, and the fixing block is threadedly connected to the screw rod.

[0021] By adopting the above technical solution, the screw rod limits the fixed block, thereby reducing the rotation of the fixed block under the action of its own gravity.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. By setting the fixing plate, fixing block, guide rod and rotating assembly, the relative movement of two H-shaped steels with the same length direction along their own width direction is reduced, and the supporting effect of the H-shaped steel on the roof is maintained;

[0024] 2. By setting a driving spring and a driving plate, the fixing plate can be driven to rotate so that the fixing plate and the fixing hole are misaligned;

[0025] 3. By setting a pressure plate and a clamping spring, the movement of the driving plate can be controlled, thereby controlling the rotation of the fixed block. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-4 This application is described in further detail.

[0032] The present application embodiment discloses an H-shaped steel. Figure 1 The H-shaped steel comprises two flanges 1 parallel to each other and a web 2 arranged between the two flanges 1. The web 2 is perpendicular to the flanges 1, and the length direction of the web 2 is consistent with that of the flanges 1. The upper and lower surfaces of the web 2 are fixedly connected to the corresponding flanges 1. Two fixing plates 3 are provided at one end of the H-shaped steel. The fixing plates 3 are located between the two flanges 1, and the web 2 is located between the two flanges 1. The upper and lower surfaces of the fixing plates 3 are fixedly connected to the corresponding flanges 1, and a plug-in hole 31 is formed between the fixing plates 3 and the web 2.

[0033] Reference Figure 1 and Figure 2 One end of the H-shaped steel away from the fixed plate 3 is fixedly connected with a plug-in plate 4 corresponding to the plug-in hole 31, and the side of the plug-in plate 4 away from the fixed plate 3 is located outside the H-shaped steel, and the length direction of the plug-in plate 4 is consistent with the length direction of the web 2; a mounting groove 41 is opened on the side wall of the plug-in plate 4 away from the web 2, and the mounting groove 41 is located outside the H-shaped steel, and the length of the mounting groove 41 is not equal to the width of the mounting groove 41. In this embodiment, the length of the mounting groove 41 is less than the width of the mounting groove 41.

[0034] A guide rod 5 perpendicular to the bottom wall of the mounting groove 41 is provided in the mounting groove 41. The cross-section of the guide rod 5 is rectangular, and the guide rod 5 is slidably inserted into the plug-in board 4; a screw rod 6 is fixedly connected to the end surface of the guide rod 5 away from the web 2, and the length direction of the screw rod 6 is consistent with the length direction of the guide rod 5. A fixing block 7 corresponding to the mounting groove 41 is threadedly connected to the screw 6, and the fixing block 7 is slidably inserted into the mounting groove 41.

[0035] The side wall of the fixing block 7 away from the web 2 is inclined, and the inclined side wall of the fixing block 7 gradually inclines from the side away from the end of the H-shaped steel to the side close to the end of the H-shaped steel toward the side away from the web 2; a fixing hole 32 corresponding to the fixing block 7 is opened on the fixing plate 3, and the fixing hole 32 passes through the fixing plate 3; a connecting spring 8 is jointly sleeved on the guide rod 5 and the screw rod 6, and the connecting spring 8 is located between the bottom wall of the mounting groove 41 and the fixing block 7, and the connecting spring 8 is fixedly connected to the bottom wall of the mounting groove 41, and one end of the connecting spring 8 close to the fixing block 7 contacts the fixing block 7; when the connecting spring 8 is in a natural state, the fixing block 7 is located outside the mounting groove 41 as a whole.

[0036] When two H-shaped steels with the same length direction need to be fixed to the column, the operator aligns the plug-in plate 4 of one of the H-shaped steels with the plug-in hole 31 of the other H-shaped steel, and then pushes the H-shaped steel corresponding to the plug-in plate 4 to move the plug-in plate 4 into the plug-in hole 31; when the screw 6 moves to the fixing plate 3, the operator pushes the fixing block 7 into the installation groove 41, and the movement of the fixing block 7 drives the guide rod 5 to move, and at the same time the fixing block 7 compresses the connecting spring 8.

[0037] When the inclined side wall of the fixing block 7 contacts the side wall of the fixing plate 3 close to the web 2, the operator delivers the plug board 4 into the plug hole 31 and releases the fixing block 7. As the plug board 4 continues to move into the plug hole 31, the fixing plate 3 pushes the fixing block 7 to continue to move into the mounting groove 41 until the fixing block 7 is entirely located in the mounting groove 41. When the fixing block 7 moves to align with the fixing hole 32, the connecting spring 8 restores its deformation and pushes the fixing block 7 to move out of the mounting groove 41. When the connecting spring 8 returns to its natural state, the fixing block 7 is located on the side of the fixing plate 3 away from the web 2.

[0038] At this time, it is necessary to rotate the fixing block 7 so that the fixing block 7 is rotated to be misaligned with the fixing hole 32, so that the fixing block 7 cooperates with the fixing hole 32 to fix the two H-shaped steels, reducing the relative movement of the two H-shaped steels along their own width direction, and maintaining the supporting effect of the H-shaped steel on the roof; in order to make it more convenient for operators to fix the two H-shaped steels, a rotating component 9 corresponding to the fixing block 7 is also provided at one end of the H-shaped steel close to the fixing plate 3, and the rotating component 9 and the corresponding fixing block 7 are located on the same side of the web 2, and the rotating component 9 is located between the two flanges 1.

[0039] Reference Figure 1 and Figure 3 The rotating assembly 9 includes a driving member 91 for driving the fixed block 7 to rotate and a control member 92 for controlling the operation of the driving member 91; the driving member 91 includes a driving plate 911 slidably connected to the lower surface of the upper flange 1, the driving plate 911 is located on the side of the fixed plate 3 away from the web 2, and the driving plate 911 is in contact with the side wall of the fixed plate 3 that is close to each other, and the lower surface of the driving plate 911 is lower than the upper hole wall of the fixing hole 32.

[0040] A plurality of connecting blocks 912 are fixedly connected to the upper surface of the driving plate 911. In the present embodiment, the number of the connecting block 912 is one. A connecting groove 11 corresponding to the connecting block 912 is provided on the lower surface of the upper flange 1. The length direction of the connecting groove 11 is consistent with the length direction of the flange 1. The connecting block 912 is slidably inserted into the connecting groove 11. The connecting block 912 cooperates with the connecting groove 11 so that the driving plate 911 can slide along the length direction of the H-shaped steel.

[0041] A driving spring 913 is fixedly connected to the groove wall of the connecting groove 11 near the middle end of the H-shaped steel, and the driving spring 913 is fixedly connected to the side wall corresponding to the connecting block 912; when the driving spring 913 is in a natural state, the side wall of the driving plate 911 near the end face of the H-shaped steel is located on the side of the fixing hole 32 near the end face of the H-shaped steel.

[0042] The control member 92 includes a pressure plate 921 slidably connected to the upper surface of the lower flange 1. The length direction of the pressure plate 921 is set along the length direction of the H-shaped steel, and the upper surface of the pressure plate 921 is higher than the lower surface of the driving plate 911; a plurality of sliders 922 are fixedly connected to the lower surface of the pressure plate 921. In this embodiment, the number of sliders 922 is two, and the two sliders 922 are distributed along the length direction of the pressure plate 921.

[0043] A slide groove 12 corresponding to the slider 922 is provided on the upper surface of the lower flange 1. The length direction of the slide groove 12 is arranged along the width direction of the H-shaped steel. Each slider 922 is slidably inserted in the corresponding slide groove 12. A pressing spring 923 is fixedly connected to the end of the slide groove 12 away from the web 2. The end of the pressing spring 923 close to the slider 922 is fixedly connected to the slider 922. The pressing spring 923 is always in a compressed state, and the pressure plate 921 is in contact with the fixed plate 3.

[0044] Reference Figure 1 and Figure 4In the initial state, the pressure plate 921 is in contact with the fixed plate 3, the driving plate 911 is located on the side of the pressure plate 921 away from the end face of the H-shaped steel, and the driving plate 911 is in contact with the pressure plate 921. At this time, the driving spring 913 is in a compressed state; in the process of the fixed block 7 moving out of the plug-in hole 31, the fixed block 7 moves and pushes the pressure plate 921 to move in the direction away from the fixed plate 3, and the pressure plate 921 moves to further compress the pressing spring 923.

[0045] When the pressure plate 921 moves, the pressure plate 921 and the driving plate 911 move relative to each other. When the pressure plate 921 loses contact with the driving plate 911, the fixed block 7 is located on the side of the fixed plate 3 away from the web 2. At this time, the driving spring 913 restores its deformation and pushes the driving plate 911 to move toward the direction close to the end face of the H-shaped steel. The driving plate 911 moves and pushes the fixed block 7 to rotate.

[0046] When the driving spring 913 returns to its natural state, the driving plate 911 is located above the fixed block 7, and the fixed block 7 is offset from the fixing hole 32. The screw 6 fixes the position of the driving block to reduce the driving block's self-rotation under the action of its own gravity. At this time, the pressure plate 921 abuts against the fixed block 7, further reducing the possibility of the driving block's self-rotation. When the fixed block 7 completes rotation, the operator fixes the H-shaped steel to the column with bolts and nuts.

[0047] The implementation principle of an H-shaped steel in an embodiment of the present application is as follows: when it is necessary to fix two H-shaped steels of the same length direction, the operator first plugs the plug-in board 4 into the plug-in hole 31, and at the same time presses the fixing block 7 into the mounting groove 41 so that the fixing block 7 is partially located in the plug-in hole 31, and then the operator releases the fixing block 7 and continues to push the plug-in board 4; when the fixing block 7 is aligned with the fixing hole 32, the connecting spring 8 restores its deformation and pushes the fixing block 7 to move outward, and when the fixing block 7 contacts the pressure plate 921, the fixing block 7 moves and pushes the pressure plate 921 to move.

[0048] When the connecting spring 8 pushes the fixing block 7 to the side of the fixing plate 3 away from the web 2, the pressure plate 921 is out of contact with the driving plate 911, the driving spring 913 recovers its deformation and pushes the driving plate 911 to move, the driving plate 911 moves and pushes the fixing block 7 to rotate, so that the fixing block 7 is misaligned with the fixing hole 32; finally, the operator uses bolts and nuts to fix the H-shaped steel to the column.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
