Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a temporary fixing device for the bottom of an I-beam. Background Technology

[0002] In steel structure buildings, due to construction requirements, some tools and equipment need to be reliably connected to the structure before use. Since welding is not allowed on the I-beams that serve as load-bearing beams, bolt holes are usually pre-drilled in the structural floor slab to embed lifting rings, or holes are drilled later to connect or fix the equipment. However, pre-drilling bolt holes or drilling later increases the construction process and can have a certain impact on the structural quality. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a temporary fixing device for the bottom of I-beams, which can not only provide good support, but also facilitate quick installation and dismantling, and can provide a temporary and reliable force-bearing point for equipment such as climbing frames, suspended baskets, manual hoists, and pulleys.

[0004] This utility model is achieved by the following technical solution:

[0005] A temporary fixing device for the bottom of an I-beam includes a limiting clip, a fixing clip, a support beam, and a support base. A limiting clip is provided on the upper surface of one end of the support beam, and a fixing clip is provided on the upper surface of the other end. A support base is provided on the lower surface of the support beam. The limiting clip includes a first rectangular steel pipe and a second rectangular steel pipe. The support beam uses a fourth rectangular steel pipe, and a second connecting hole is provided on the side of the fourth rectangular steel pipe. The fixing clip uses a T-shaped structure where a horizontal third rectangular steel pipe is fixedly connected to a set of vertical connecting plates. The first rectangular steel pipe is fixed to the upper surface of the fourth rectangular steel pipe via the second rectangular steel pipe. The first connecting hole and the second connecting hole on the connecting plate are fixed together by a bolt assembly.

[0006] Furthermore, a support block is provided on the lower right end surface of the third rectangular steel pipe.

[0007] Furthermore, the second rectangular steel pipe and the support block have the same height, and the height of the second rectangular steel pipe is set according to the thickness of the I-beam that needs to be supported.

[0008] Furthermore, the support base is formed by two trapezoidal support plates symmetrically fixed on both sides of the fourth rectangular steel pipe; the trapezoidal support plates are provided with a fourth connecting hole for fixing with the telescopic rod.

[0009] Furthermore, the side of the fourth rectangular steel pipe is provided with a plurality of third connecting holes; the side of the trapezoidal support plate is provided with a set of fifth connecting holes corresponding to the third connecting holes, and the third connecting holes are fixed to the fifth connecting holes by bolt assemblies.

[0010] In summary, this utility model has the following beneficial effects: it can provide good and safe support for I-beams, and is easy to operate and install. The equipment can be tied or fixed by the fixing device, overcoming the technical problem that welding is not allowed on I-beams as load-bearing beams, thus making it impossible to reliably connect tools and equipment to the structure.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Example 1: As Figures 1 to 3As shown, a temporary fixing device for the bottom of an I-beam includes a limiting clip 1, a fixing clip 2, a support beam 3, and a support base 4. The upper surface of one end of the support beam 3 is provided with the limiting clip 1, and the upper surface of the other end is provided with the fixing clip 2. The lower surface of the support beam 3 is provided with the support base 4. The limiting clip 1 includes a first rectangular steel pipe 101 and a second rectangular steel pipe 102. The support beam 3 uses a fourth rectangular steel pipe 301, and the side of the fourth rectangular steel pipe 301 is provided with a second connecting hole 302. The fixing clip 2 is a T-shaped structure that is fixedly connected to a horizontal third rectangular steel pipe 201 and a set of vertical connecting plates 202. The first rectangular steel pipe 101 is fixed to the upper surface of the fourth rectangular steel pipe 301 through the second rectangular steel pipe 102. The first connecting hole 204 and the second connecting hole 302 on the connecting plate 202 are fixed by a bolt assembly.

[0019] As a preferred embodiment, such as Figure 2 and Figure 3 As shown, a support block 203 is provided on the lower right surface of the third rectangular steel pipe 201. The support block 203 is connected to the upper surface of the fourth rectangular steel pipe 301 through abutment, so as to ensure the stability of the connection.

[0020] As a preferred embodiment, the second rectangular steel pipe 102 and the support block 203 have the same height, and the height of the second rectangular steel pipe 102 is set according to the thickness of the I-beam that needs to be supported.

[0021] As a preferred embodiment, such as Figure 2 As shown, the support base 4 is formed by two trapezoidal support plates 401 symmetrically fixed on both sides of the fourth rectangular steel pipe 301; the trapezoidal support plates 401 are provided with fourth connecting holes 402 for fixing to the telescopic rod. The wider end of the trapezoidal support plate 401 is welded and fixed to both sides of the fourth rectangular steel pipe 301 to improve the support strength.

[0022] Example 2: As Figure 4 and Figure 5 As shown, the side of the fourth rectangular steel pipe 301 is also provided with multiple third connecting holes 303; the side of the trapezoidal support plate 401 is provided with a set of fifth connecting holes 403 corresponding to the third connecting holes 303, and the third connecting holes 303 are fixed to the fifth connecting holes 403 by bolt assemblies. The multiple third connecting holes 303 allow for adjustment of the position of the support base 4, ensuring optimal support and providing a stable force point for the installation of tools and equipment. Simultaneously, the device is detachable and reusable, allowing for adjustment and reuse according to the environment of different I-beam construction sites.

[0023] Application example: This temporary fixing device is installed at the bottom of the I-beam where tools and equipment (such as climbing scaffolds, suspended baskets, manual hoists, and pulleys) need to be installed. The first rectangular steel pipe 101 is welded to the upper surface of the fourth rectangular steel pipe 301 through the second rectangular steel pipe 102 to form a snap-fit ​​interface. This interface is then snapped onto the I-beam. The connecting plate 202 of the fixing clip 2 is then snapped onto the upper surface of the fourth rectangular steel pipe 301 and fixed with bolts. Finally, the upper end of the telescopic rod in contact with the ground is connected to the fourth connecting hole 4 of the support base 4. 02. Connect and adjust the length of the telescopic rod so that it is perpendicular to the support base 4. Then connect the necessary tools and equipment to this temporary fixing device to make it a reliable load-bearing point for installation. This avoids the damage to the structural floor slab caused by pre-drilling screw holes or pre-embedding lifting rings in the conventional method or drilling holes later to tie or fix the equipment. At the same time, this temporary fixing device can support the I-beam and can be disassembled and reused, which greatly reduces construction costs and improves construction quality.

[0024] Although the specific embodiments of this utility model have been described and explained in detail above, it should be noted that various equivalent changes and modifications can be made to the above embodiments based on the concept of this utility model. As long as the resulting functions do not exceed the spirit covered by the specification, they should all be within the protection scope of this utility model.
