[0023] The above and other technical features and advantages of the present invention are described in more detail below in conjunction with the accompanying drawings.

[0024] Embodiment 1

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, Figure 1 It is a schematic diagram of the use state of the U-shaped clamp for fixing the H-shaped steel; Figure 2 This is a structural view of the U-shaped clamp for fixing the H-shaped steel in this embodiment; Figure 3 for Figure 1 A partial structural view from perspective A.

[0026] The U-shaped clamp for fixing the H-shaped steel in the utility model comprises a connecting plate 3 and a clamping rod 5, wherein a U-shaped groove is arranged in the connecting plate 3 to form a U-shaped structure as a whole, and connecting blocks 4 and supporting blocks 6 are respectively arranged at both ends of the connecting plate 3, and a clamping hole is arranged on the connecting block 4, and the clamping rod 5 is threadedly connected in the clamping hole, and one end of the clamping rod 5 is arranged corresponding to the supporting block 6, and the supporting block 6 is arranged in contact with the wing plate of the tire frame 1, and the end of the clamping rod 5 corresponding to the supporting block 6 is arranged in contact with the wing plate of the H-shaped steel 2, and the wing plates of the tire frame 1 and the H-shaped steel 2 can be clamped between the clamping rod 5 and the supporting block 6 by rotating the clamping rod 5, thereby achieving the clamping and fixing effect of the tire frame 1 and the H-shaped steel 2.

[0027] Preferably, the thickness of the connecting plate 3 is not less than 30 mm to ensure the overall structural strength of the U-shaped clamp for fixing the H-shaped steel to ensure the clamping and fixing effect.

[0028] The clamping rod 5 may be a threaded screw, and the cross-sectional diameter of the clamping rod 5 is not less than 30 mm.

[0029] The connecting block 4 can be made of ordinary round steel and fixed to the end of the connecting plate 3 by welding. The threaded inner part of the clamping hole is matched with the clamping rod 5.

[0030] Preferably, a mounting hole 51 is provided at the end of the clamping rod 5 away from the supporting block 6, and the mounting rod can be inserted into the mounting hole 51 to facilitate the rotation of the clamping rod 5 so as to perform the disassembly and assembly operation of the U-shaped clamp fixing the H-beam.

[0031] The width of the U-shaped groove on the connecting plate 3 is not less than 100 mm, and the depth of the U-shaped groove is not less than 100 mm, so as to ensure that sufficient space is provided to place the tire frame 1 and the wing plate of the H-shaped steel 2 in the U-shaped groove.

[0032] Preferably, the supporting block 6 is provided with a supporting plate in the U-shaped groove, and the supporting plate is made of rubber material. The supporting block 6 is provided in contact with the tire frame 1 or the H-shaped steel 2 through the supporting plate, thereby ensuring that the supporting block 6 is tightly fitted with the tire frame 1 or the H-shaped steel 2 to achieve effective clamping and fixation.

[0033] The utility model compresses the H-shaped steel 2 and the tire frame 1 by the connecting plate 3 and the clamping rod 5, which changes the traditional fixing method that can only use diagonal braces. After the clamping rod 5 is tightened, it is reliably fixed to the H-shaped steel 2 and the tire frame 1, the safety performance is improved, and the disassembly and assembly efficiency is greatly improved.

[0034] The raw materials of the utility model can be steel plates and screw rods, the structure is simple and easy to process, the materials are easy to obtain, and the operation is simple. The utility model is convenient to repair and replace.

[0035] Embodiment 2

[0036] The connecting plate 3 is also provided with a locking portion, which is provided corresponding to the connecting block 4 and is used to fix the position of the clamping rod 5 on the connecting block 4, thereby further strengthening the compression and fixing effect of the H-beam 2 and the tire frame 1.

[0037] like Figure 4 As shown, Figure 4 The structural view of the present embodiment of the U-shaped clamp for fixing the H-shaped steel. Specifically, the locking part includes a fixing block 71, a locking rod 72 and a locking block 73. The fixing block 71 is fixedly arranged on the connecting plate 3, and the fixing block 71 and the supporting block 6 are arranged on both sides of the connecting block 4. A locking hole is arranged on the fixing block 71, and the locking rod 72 is threadedly connected in the locking hole. The locking block 73 is fixedly arranged at the end of the locking rod 72, and the axis of the locking rod 72 is arranged perpendicular to the axis of the clamping rod 5. By rotating the locking rod 72, the locking block 73 can be brought into contact with the clamping rod 5, so that the position of the clamping rod 5 can be fixed.

[0038] Generally, a mounting block is provided at the end of the locking rod 72 away from the locking block 73 , and the mounting block is configured as a block-shaped piece with a polygonal cross-section, so as to facilitate the screwing of the locking rod 72 by a wrench or the like.

[0039] Preferably, the clamping rod 5 is provided with a plurality of locking grooves 52 along the axial direction, the locking grooves 52 are arranged in a circular ring shape with the axis of the clamping rod 5 as the center, the locking grooves 52 are arranged corresponding to the locking blocks 73, and the locking blocks 73 are arranged in a hemispherical block. Since the wing plate thicknesses of the H-beam 2 and the tire frame 1 generally adopt a relatively fixed dimensional thickness, when the H-beam 2 and the tire frame 1 are clamped and fixed by the clamping rod 5, the locking blocks 73 can be arranged in the corresponding locking grooves 52 by twisting the locking rod 72, so that the clamping rod 5 can be locked in the axial position to ensure the clamping and fixing effect of the clamping rod 5 and the supporting block 6 on the H-beam 2 and the tire frame 1.

[0040] Generally, the cross-section of the locking groove 52 is set to be a V-shaped groove, and the groove width of the locking groove 52 is slightly larger than the diameter of the locking block 73, so that it is convenient to set the locking block 73 in the locking groove 52, so that the locking block 73 contacts the groove wall of the locking groove 52, thereby achieving a positioning effect.

[0041] Embodiment 3

[0042] like Figure 5 As shown, Figure 5 The structural view of the U-shaped clamp for fixing the H-shaped steel in this embodiment. In this embodiment, a positioning block 53 is provided on the clamping rod 5, and the positioning block 53 is set as a sleeve structure. The positioning block 53 is sleeved on the clamping rod 5, and the positioning block 53 and the clamping rod 5 are threadedly connected. A positioning groove 54 is provided on the positioning block 53, and the positioning groove 54 is set as a circular ring centered on the axis of the clamping rod 5. The positioning block 53 and the U-shaped groove are respectively arranged on both sides of the connecting block 4, and the relative rotation of the positioning block 53 and the clamping rod 5 can realize the position movement of the positioning block 53 on the clamping rod 5.

[0043] After the H-beam 2 and the tire frame 1 are clamped and fixed by the clamping rod 5, the positioning block 53 is sleeved on the end of the clamping rod 5 and rotated to adjust the position so that the positioning groove 54 corresponds to the height position of the locking rod 72, so that the locking block 73 is inserted into the positioning groove 54 for position locking. This structure is suitable for clamping and fixing the H-beam 2 and the tire frame 1 of non-standard structures.

[0044] Similarly, the cross-section of the positioning groove 54 is set to be a V-shaped groove, and the groove width of the positioning groove 54 is slightly larger than the diameter of the locking block 73, so that it is convenient to set the locking block 73 in the positioning groove 54, so that the locking block 73 contacts the groove wall of the positioning groove 54, thereby achieving a positioning effect.

[0045] The above is only a preferred embodiment of the utility model, which is only illustrative and not restrictive. Those skilled in the art understand that many changes, modifications, and even equivalences can be made within the spirit and scope defined by the claims of the utility model, but they will all fall within the scope of protection of the utility model.
