Description

Technical Field

[0001] This utility model relates to the technical field of temporary support structures at construction sites, specifically a cantilevered I-beam anti-slip structure. Background Technology

[0002] In construction engineering, cantilevered I-beams are commonly used for temporary support systems such as scaffolding or working platforms. Traditional methods of fixing cantilevered I-beams have the following drawbacks: First, welding is used for fixing, such as welding directly to embedded parts or welding metal blocks (commonly known as "welded brackets") to the bottom of the cantilevered I-beam. This method requires specialized welding equipment, and because the welding area of ​​the cantilevered I-beam usually extends to the outside of the supporting beam, the operating space is limited, making welding operations very inconvenient. Furthermore, after the project is completed, the welded areas need to be cut and removed, which is cumbersome, inefficient, and damages the I-beam itself, hindering material reuse. Second, U-bolts are used for securing. While this method is relatively simple to operate and does not require hot work, it is often not secure enough and is prone to slippage under load, posing significant safety hazards and lacking reliability.

[0003] Therefore, there is a need for a cantilevered I-beam anti-slip fixing structure that is easy to install, reliably fixed, requires no welding, and is easy to disassemble and recycle. Utility Model Content

[0004] The purpose of this utility model is to provide a cantilevered I-beam anti-slip structure to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a cantilevered I-beam anti-slip structure, comprising:

[0006] A crossbar, wherein a fixing port for inserting the web of an I-beam is provided on the crossbar, and a threaded hole communicating with the fixing port is provided on the crossbar, wherein a fixing bolt for abutting the flange of the I-beam is installed in the threaded hole;

[0007] The crossbar is also provided with a positioning port;

[0008] The tightening screw is rotatably installed in the positioning port through a threaded connection, and one end of the tightening screw is used to tighten against the support beam a.

[0009] Furthermore, a rubber pad is fixedly provided at the end of the fixing bolt, and the compression deformation of the rubber pad provides an anti-loosening reaction force.

[0010] Furthermore, at least one positioning port is provided on the crossbar, and the inner wall of the positioning port is threaded. A tightening screw is rotatably installed in the positioning port through threaded engagement. One end (non-working end) of the tightening screw is provided with a rotating block for rotational drive, and the other end (working end) is used to press against the side of the poured concrete support beam, thereby axially limiting the crossbar.

[0011] Furthermore, a pressure plate is rotatably connected to the working end of the tightening screw. Specifically, a connecting ring is rotatably mounted on one side of the pressure plate. Radial threaded holes are formed on the side wall of the connecting ring and at corresponding positions on the working end of the tightening screw. The connecting ring is fixedly connected to the working end of the tightening screw by bolts, allowing the pressure plate to rotate freely relative to the tightening screw without axially disengaging. The pressure plate is located between the tightening screw and the support beam to increase the contact area and distribute the tightening force.

[0012] Furthermore, two clamping rings are threadedly installed on the tightening screw on both sides of the crossbar. Tightening the two clamping rings clamps it to both sides of the crossbar. The clamping rings provide a reaction force to the tightening screw, thereby auxiliaryly fixing the position of the tightening screw relative to the crossbar and preventing it from loosening and rotating during use.

[0013] Furthermore, a rotating block is fixedly installed at the end of the tightening screw away from the support beam a. The rotating block has a regular hexagonal structure and can be rotated using a pipe wrench or an adjustable wrench.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model, by setting a crossbar, a tightening screw, and a fixing port for installation with the I-beam, allows the crossbar, tightening screw, and I-beam to be installed together on the ground and hoisted onto the support beam a. Only a small amount of rotation of the tightening screw is needed to fix the I-beam on the support beam a, making installation and disassembly relatively convenient.

[0016] The crossbars, tightening screws, and I-beams are reusable. The tightening screws can be adjusted in position on the crossbars to accommodate support beams of different widths, making them highly versatile. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see 1- Figure 3 As shown, this embodiment discloses a cantilevered I-beam anti-slip structure, including a metal crossbar 1, with multiple evenly distributed fixing holes 2 on the crossbar 1, into which I-beams 5 are inserted. Figure 1 and Figure 2 As shown, the crossbar 1 is located at both ends of the I-beam 5. Threaded holes are provided on the upper and / or lower sides of the crossbar 1, and fixing bolts 3 are installed in these holes. When tightened, the threaded end of the fixing bolt 3 abuts against the upper and lower sides of the I-beam 5, fixing and limiting the I-beam 5. In this embodiment, a rubber pad is fixedly installed on the threaded end of the fixing bolt 3. When the fixing bolt 3 is tightened, the rubber pad is compressed, providing an axial reaction force to the fixing bolt 3, thus preventing loosening.

[0024] Alternatively, threaded holes matching the fixing bolts 3 can be made on the upper and lower side walls at both ends of the I-beam 5. The fixing bolts 3 can be inserted into the threaded holes of the crossbar 1 and the I-beam 5 to fix them together. This fixing method is more secure and stable.

[0025] The crossbar 1 is also provided with multiple positioning holes, the inner wall of which is threaded. A tightening screw 4 is rotatably installed in the positioning hole. A rotating block (preferably a regular hexagon) is fixedly welded to the non-working end of the tightening screw 4. Rotating the rotating block causes the tightening screw 4 to rotate, and under the action of the threads, it moves along the axial direction of the positioning hole. The working end of the tightening screw 4 contacts and tightens with the already cast support beam a, limiting the movement of the crossbar 1. This prevents the crossbar 1 and the I-beam 5 from moving in the cantilever direction.

[0026] Example 2

[0027] Further improvements made based on Example 1, such as Figure 4As shown, two clamping rings 8 are threadedly installed on the top screw 4. The clamping rings 8 are located on both sides of the crossbar 1. When the two clamping rings 8 are tightened, they clamp the crossbar 1 and fix the top screw 4 to prevent the top screw 4 from loosening during use.

[0028] In actual use, when the tightening screw 4 is rotated and tightened, its working end comes into contact with the side wall of the support beam a, which may cause the solidified concrete surface layer of the support beam a to fall off or wear under the squeezing force of the tightening screw 4.

[0029] Therefore, in a further embodiment, a pressure plate 6 is rotatably mounted on the end of the tightening screw 4 that contacts the support beam a. A connecting ring 7 is rotatably mounted on one side wall of the pressure plate 6. The connecting ring 7 is fitted onto the rotating shaft on the back of the pressure plate 6 via a bearing or loose fit, allowing it to rotate relative to the pressure plate 6. The side wall of the connecting ring 7 has radially arranged threaded holes. The inner diameter of the connecting ring 7 is the same as the working end diameter of the tightening screw 4. The working end of the tightening screw 4 also has radially arranged threaded holes. The connecting ring 7 and the working end of the tightening screw 4 are bolted together. The pressure plate 6 can fit against the concrete surface. When the tightening screw 4 rotates to tighten, the connecting ring 7 and the pressure plate 6 rotate relative to each other, while the pressure plate 6 itself does not rotate. This achieves the tightening function and also disperses the pressure through the pressure plate 6, protecting the concrete surface layer.

[0030] The installation process of this utility model is as follows: First, on the ground, place the crossbar 1 through the fixing port 2 onto both ends of the I-beam 5; then tighten the fixing bolts 3 to fix the I-beam 5; next, rotate one of the clamping rings 8 onto the tightening screw 4, screw the tightening screw 4 into the positioning port of the crossbar 1, and then rotate the other clamping ring 8 onto the tightening screw 4; install the connecting ring 7 on the working end of the tightening screw 4, thus completing the installation of the crossbar 1, the I-beam 5, and the tightening screw 4. The two clamping rings 8 can be rotated to both ends of the tightening screw 4 respectively.

[0031] During installation, a crane is used to lift the above structure onto the support beam a. Four connecting cables extend from the end of the crane's cable. The hooks of the connecting cables are wrapped around the two outermost H-beams 5, and the hooks are attached to the connecting cables to complete the installation of the cables and the above structure. Then, the crane can be started to carry out the lifting work.

[0032] After hoisting onto support beam a, first rotate the tightening screw 4 at one end of the I-beam 5 so that the pressure plate 6 contacts the side of support beam a. Then rotate the tightening screw 4 at the other end of the I-beam 5 so that its working end tightly presses against the side of support beam a through the pressure plate 6. Finally, tighten the two clamping rings 8 on the tightening screw 4, which clamp the crossbar 1, completing the installation of the entire anti-slip structure. Disassembly is performed in the reverse order.

[0033] Depending on actual usage requirements, the crossbar 1, I-beam 5, and tightening screw 4 can also be installed on the support beam a. First, place the crossbar 1 onto the web of the already positioned I-beam 5 through its fixing port 2; then tighten the fixing bolts 3 to secure the I-beam 5; next, rotate one of the clamping rings 8 onto the tightening screw 4, screw the tightening screw 4 into the positioning port of the crossbar 1, and then rotate the other clamping ring 8 onto the tightening screw 4; install the connecting ring 7 on the working end of the tightening screw 4, rotate the tightening screw 4 at one end of the I-beam 5 so that the pressure plate 6 contacts the side of the support beam a, then rotate the tightening screw 4 at the other end of the I-beam 5 so that its working end tightly presses against the side of the support beam a through the pressure plate 6; finally, tighten the two clamping rings 8 on the tightening screw 4 to complete the installation of the entire anti-slip structure. Disassembly is performed in the reverse order.

[0034] The tensioning screw 4 can be axially adjusted to maintain the distance between itself and the support beam a, adapting to support beams a of different sizes. It is highly versatile, easy to install and disassemble, and reusable.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
