Description

Technical Field

[0001] The present application relates to the technical field of cantilever I-beam fixing equipment, and in particular to a cantilever I-beam fixing device. Background Art

[0002] When fixing the traditional cantilever I-beam, Figure 1 As shown, the cantilever I-beam 100 is embedded in a structural U-shaped round steel 200, thereby securing the cantilever I-beam 100 via the U-shaped round steel 200. However, in order to facilitate the cantilever I-beam 100 passing through the U-shaped round steel 200, the width of the cantilever I-beam 100 needs to be smaller than the width of the U-shaped round steel 200. In addition, due to the I-shaped structure of the cantilever I-beam 100 itself, there is a large gap 300 between the cantilever I-beam 100 and the U-shaped round steel 200, which makes the cantilever I-beam 100 unstable and prone to displacement.

[0003] Therefore, the existing technology still needs to be improved and developed. Utility Model Content

[0017] The cantilever I-beam fixing device comprises two adjacent right-angled triangle teeth, wherein the right-angled side of one right-angled triangle tooth is connected to the hypotenuse of the other right-angled triangle tooth to form a right-angled triangle groove between the two adjacent right-angled triangle teeth.

[0027] To make the purpose, technical solutions and advantages of this application clearer and more explicit, the following further describes this application in detail with reference to the accompanying drawings and examples. It should be understood that the specific examples described herein are only used to explain this application and are not intended to limit this application.

[0028] This application provides a cantilever I-beam fixing device, such as Figure 2 As shown, the cantilevered I-beam fixing device includes a base plate 1, a clamping plate 2 and an elastic member 3; the first end of the clamping plate 2 is rotatably connected to the first end of the base plate 1 to form an adjustable angle between the base plate 1 and the clamping plate 2; the elastic member 3 is respectively connected to the second end of the clamping plate 2 and the second end of the base plate 1; the base plate 1, the clamping plate 2 and the elastic member 3 are combined to form a triangle to be inserted into the gap between the cantilevered I-beam and the U-shaped round steel.

[0029] Specifically, the two ends of the base plate 1 in the longitudinal direction are the first end of the base plate 1 and the second end of the base plate 1, respectively; the two ends of the clamping plate 2 in the longitudinal direction are the first end of the clamping plate 2 and the second end of the clamping plate 2, respectively. The clamping plate 2, the base plate 1, and the elastic member 3 together form a triangular structure, i.e., a triangular wedge-shaped structure. When inserted into the gap between the cantilevered I-beam and the U-shaped round steel, the base plate 1 supports the cantilevered I-beam, and the clamping plate 2 supports the U-shaped round steel, thereby filling the gap between the cantilevered I-beam and the U-shaped round steel and securing the cantilevered I-beam, thereby reducing or even preventing displacement of the cantilevered I-beam.

[0030] The elastic member 3 can produce elastic deformation under the action of pressure, thereby changing the angle between the card plate 2 and the base plate 1, and the connection between the first end of the card plate 2 and the first end of the base plate 1 is a rotational connection. Therefore, when an external force acts on the card plate 2 or the external force is withdrawn, the elastic member 3 can produce elastic deformation or restore elastic deformation, and the angle between the card plate 2 and the base plate 1 can be reduced or increased.

[0031] In specific applications, the clamping plate 2 can be pressed to compress the elastic member 3, and the angle between the clamping plate 2 and the base plate 1 is reduced, thereby inserting the triangular overall structure into the gap between the cantilevered I-beam and the U-shaped round steel; after releasing the clamping plate 2, the elastic member 3 restores its elastic deformation, and the angle between the clamping plate 2 and the base plate 1 increases until the clamping plate 2 is against the U-shaped round steel and the base plate 1 supports the cantilevered I-beam, thereby achieving fixation of the cantilevered I-beam.

[0032] When adapting to different construction structures, cantilever I-beams and U-shaped round steels need to adopt different specifications. Therefore, the width of the gap between the cantilever I-beams and U-shaped round steels when they are assembled is not a fixed value. In this application, since the angle between the clamping plate 2 and the base plate 1 is adjustable, the cantilever I-beam fixing device can be applied to the assembly structure of cantilever I-beams and U-shaped round steels of different specifications, thereby expanding the scope of application of the cantilever I-beam fixing device; and the cantilever I-beam fixing device can be assembled by pressing and releasing the clamping plate 2, thereby improving the assembly flexibility and convenience of the cantilever I-beam fixing device.

[0033] In one embodiment of the present application, the cantilevered I-beam fixing device also includes a rigid connecting rod 4; the rigid connecting rod 4 passes through the elastic member 3, one end of the rigid connecting rod 4 is connected to the second end of the base plate 1, and the other end extends toward the clamping plate 2 and exceeds the elastic member 3; the rigid connecting rod 4 is perpendicular to the base plate 1.

[0034] In this embodiment, the rigid connecting rod 4 is additionally provided in the elastic member 3, so that when the elastic member 3 is deformed, it mainly deforms along the rigid connecting rod 4, and is not prone to large bending deformation, thereby ensuring the supporting force of the elastic member 3 on the clamping plate 2, thereby achieving the purpose of enhancing the supporting force of the cantilever I-beam fixing device on the cantilever I-beam.

[0035] It can be understood that this embodiment is suitable for the scenario where the elastic member 3 only needs a slight elastic deformation to be inserted into the gap between the cantilevered I-beam and the U-shaped round steel, and restores the elastic deformation to support the cantilevered I-beam and the U-shaped round steel.

[0036] In order to further improve the applicability of the cantilever I-beam fixing device to different gap widths, in one embodiment of the present application, a slide groove 11 is provided on the card plate 2, and the slide groove 11 extends along the length direction of the card plate 2; a portion of the elastic member 3 is located in the slide groove 11 and can slide along the slide groove 11.

[0037] In this embodiment, when the card plate 2 rotates relative to the base plate 1, the elastic member 3 can slide in the slide groove 11, and the position of the card plate 2 corresponding to the elastic member 3 will change. Therefore, the slide groove 11 is set on the card plate 2, and the end of the elastic member 3 is inserted into the slide groove 11, so that even if the elastic member 3 cannot produce a large bending deformation due to the limiting effect of the rigid connecting rod 4 on the elastic member 3, the card plate 2 can also produce a large angle adjustment relative to the base plate 1, thereby improving the applicability of the cantilever I-beam fixing device to different gap widths.

[0038] In one implementation of this embodiment, Figure 3 As shown, the cantilevered I-beam fixing device also includes a limit member 5, which is arranged at one end of the elastic member 3 close to the clamping plate 2; two limit grooves 12 are provided on the clamping plate 2, and the two limit grooves 12 are distributed on both sides of the slide groove 11 and are connected to the slide groove 11; the limit member 5 is inserted into the slide groove 11 and partially extends into the limit groove 12.

[0039] Specifically, the limiting member 5 is inserted into the slide groove 11 and adapted to the limiting groove 12. The limiting member 5 is used to cooperate with the card plate 2, thereby connecting the elastic member 3 to the card plate 2 and enabling relative sliding between the elastic member 3 and the card plate 2. A portion of the limiting member 5 extends beyond the slide groove 11 and into the limiting groove 12, thereby increasing the stability of the assembly between the elastic member 3 and the card plate 2. When the card plate 2 rotates relative to the base plate 1, the limiting member 5 can slide within the slide groove 11 and the limiting groove 12 without separating from the card plate 2, thereby ensuring the stability of the triangular structure.

[0040] In one implementation of this embodiment, the limiting member 5 is a circular limiting member; a portion of the circumferential surface of the circular limiting member 5 is located in the limiting groove 12 .

[0041] In this embodiment, the use of a circular limiter 5 can improve the flexibility of the circular limiter 5 in the limiter groove 12, thereby reducing or even avoiding the jamming of the card plate 2 relative to the elastic member 3 when rotating the card plate 2, and improving the flexibility of adjusting the angle between the card plate 2 and the base plate 1.

[0042] In one embodiment of the present application, the cantilevered I-beam fixing device also includes a limit plate 6, which is slidably disposed on the rigid connecting rod 4 and is located on the side of the rigid connecting rod 4 away from the base plate 1 to support the clamping plate 2 toward the base plate 1.

[0043] The limiting plate 6 is located in the movement path of the card plate 2, thereby limiting the position of the card plate 2 and achieving the positioning of the angle between the card plate 2 and the base plate 1. When the card plate 2 and the limiting plate 6 are in contact with each other, the angle between the card plate 2 and the base plate 1 reaches its maximum; therefore, by sliding the limiting plate 6 to adjust its position on the rigid connecting rod 4, the maximum angle between the card plate 2 and the base plate 1 can be adjusted.

[0044] It can be understood that although the limit plate 6 and the rigid connecting rod 4 can slide relative to each other, the limit plate 6 and the rigid connecting rod 4 are still in contact with each other, that is, there is a large friction between the limit plate 6 and the rigid connecting rod 4, so that the limit plate 6 will not slide under the action of a small external force, thereby ensuring that the limit plate 6 is not easily displaced when limiting the card plate 2.

[0045] In order to enhance the limiting effect of the limiting plate 6 on the card plate 2, an external thread can also be provided on the end of the rigid connecting rod 4 close to the card plate 2, and a bolt can be sleeved on the rigid connecting rod 4 so that the bolt cooperates with the external thread, thereby limiting the limiting plate 6 on the side of the limiting plate 6 away from the card plate 2 by the bolt, thereby preventing the limiting plate 6 from sliding relative to the rigid connecting rod 4 under the elastic supporting action of the elastic member 3.

[0046] In one embodiment of the present application, a plurality of latch teeth 7 are provided on the clamping plate 2, and the plurality of latch teeth 7 are arranged in sequence along the length direction of the clamping plate 2; a slot 8 is formed between two adjacent latch teeth 7, and the slot 8 is used to accommodate U-shaped round steel.

[0047] Specifically, there are multiple slots 8, so that the slots 8 corresponding to the U-shaped round steel can be adjusted by adjusting the depth of the triangular structure inserted into the gap between the cantilever I-beam and the U-shaped round steel, and the U-shaped round steel can be inserted into the corresponding slots 8 to prevent the triangular structure from moving relative to the cantilever I-beam and the U-shaped round steel, thereby achieving the purpose of further improving the fixing performance of the cantilever I-beam fixing device on the cantilever I-beam.

[0048] In one implementation of this embodiment, the depth of the card slot 8 is greater than 2 cm, and the length of the bottom plate 1 is 5 cm to 8 cm.

[0049] In one embodiment of the present invention, the latching tooth 7 is a right-angled triangular latching tooth 7, wherein the hypotenuse 71 of the right-angled triangular latching tooth 7 is close to the first end of the latching plate 2, and one of the right-angled sides 72 is close to the second end of the latching plate 2. Among two adjacent right-angled triangular latching teeth 7, the right-angled side of one right-angled triangular latching tooth 7 is connected to the hypotenuse of the other right-angled triangular latching tooth 7, thereby forming a right-angled triangular latching groove between the two adjacent right-angled triangular latching teeth 7.

[0050] The structural shape of the right-angled triangle slot 8 is not only conducive to the insertion of the U-shaped round steel into it, but also conducive to limiting the U-shaped round steel through the right-angled side of the right-angled triangle slot 8, thereby preventing the U-shaped round steel from escaping from the right-angled triangle slot 8, thereby achieving the purpose of improving the fixing effect of the cantilever I-beam fixing device.

[0051] Furthermore, the inclination direction of the hypotenuse of the right-angled triangle latch 7 is more easily adapted to the direction in which the triangle structure is inserted into the gap, thereby improving the convenience of inserting the triangle structure into the gap.

[0052] In summary, the present application provides a cantilever I-beam fixing device, comprising: a base plate; a clamping plate; the first end of the clamping plate is rotatably connected to the first end of the base plate to form an adjustable angle between the base plate and the clamping plate; an elastic member is respectively connected to the second end of the clamping plate and the second end of the base plate; the base plate, the clamping plate and the elastic member together form a triangle to be inserted into the gap between the cantilever I-beam and the U-shaped round steel. The clamping plate, the base plate and the elastic member together form a triangular structure, that is, a triangular wedge structure, so that after being inserted into the gap between the cantilever I-beam and the U-shaped round steel, the base plate supports the cantilever I-beam and the clamping plate supports the U-shaped round steel, thereby filling the gap between the cantilever I-beam and the U-shaped round steel, and fixing the cantilever I-beam, reducing or even preventing the cantilever I-beam from shifting. The elastic member can produce elastic deformation under the action of pressure, thereby changing the angle between the clamping plate and the base plate, and the connection between the first end of the clamping plate and the first end of the base plate is a rotating connection. Therefore, when an external force acts on the clamping plate or the external force is withdrawn, the elastic member can produce elastic deformation or restore elastic deformation, and the angle between the clamping plate and the base plate can be reduced or increased, thereby adapting to cantilevered I-beams of different specifications.

[0053] It should be understood that the application of this application is not limited to the above examples. For ordinary technicians in this field, they can make improvements or changes based on the above description. All these improvements and changes should fall within the scope of protection of the claims attached to this application.
