Technical Field

[0001] The invention belongs to the technical field of building construction, and in particular relates to a protective device between adjacent cantilevered I-beams. Background Art

[0002] At present, cantilever I-beams have been widely used in construction projects and are inseparable from the erection of external scaffolding. It has many advantages, such as easy and quick dismantling, no reliance on tower cranes, low labor intensity, reduced risk of hoisting and installation, and no hindrance to the movement and transportation of materials by on-site construction personnel.

[0003] However, after the cantilever I-beams are installed, due to the characteristics of the spacing arrangement of the I-beams, the middle spacing is large. Regardless of whether the external frame is set up above, there is a certain gap. During the installation, the workers above are prone to step on empty space, which poses a certain safety hazard. Secondly, during the entire project promotion process, there is a gap between the scaffolding board and the external frame. During the construction process, construction debris is easy to fall through the adjacent I-beams, causing certain safety hazards to the workers below. Therefore, we propose a protective device between adjacent cantilever I-beams to solve the above problems. Summary of the invention

[0018] In order to solve the problem of potential safety hazards between adjacent cantilever I-beams, the present invention provides a protective device between adjacent cantilever I-beams. The protective device between adjacent cantilever I-beams is further described below with specific embodiments and accompanying drawings.

[0019] See also Figure 1-2 As shown, a protective device between adjacent cantilever I-beams comprises:

[0020] The protective plate connected between two adjacent cantilevered I-beams 1 is used to shield the cavity between the two adjacent cantilevered I-beams 1 in the vertical direction.

[0021] The protective device and the I-beam form a whole, which prevents the building debris above from falling through the cavity between the adjacent cantilevered I-beams 1, thus playing a certain protective role; at the same time, it also improves the overall and local stability of the I-beam.

[0022] The protection plate includes two shielding plates 3 corresponding to two adjacent cantilevered I-beams 1 respectively, and the first ends of the two shielding plates 3 are arranged opposite to each other, and the second ends of the two shielding plates 3 are respectively connected to the corresponding cantilevered I-beams 1.

[0023] The two adjacent cantilevered I-beams 1 are provided with card slots 2 on opposite sides. The protective plate further comprises two card plates 4 respectively connected to the second ends of the two shielding plates 3 , and the two card plates 4 are respectively inserted into the corresponding card slots 2 .

[0024] Furthermore, the groove on the side of the cantilevered I-beam 1 is a card slot 2, the card plate 4 is U-shaped, and the card plate 4 matches the card slot 2;

[0025] like Figure 2 , by inserting the card plate 4 into the card slot 2, the top, bottom and left side of the card plate 4 are respectively in close contact with the inner top wall, inner bottom wall and left inner wall of the card slot 2, so that the two shielding plates 3 can be installed firmly and connected between the two cantilever I-beams 1 in a flat plate shape, and the first ends of the two shielding plates 3 are in contact with each other, thereby shielding the cavity between the two adjacent cantilever I-beams 1 in the vertical direction, which can prevent the upper construction debris from falling through the cavity between the adjacent cantilever I-beams 1, thereby playing a protective effect, and also preventing workers from stepping on empty space when installing the external frame.

[0026] The protection device further comprises a support member for providing support to the first ends of the two shielding plates 3 .

[0027] The protective plate also includes two telescopic plates 5, which are respectively connected to the first ends of the two shielding plates 3 and have adjustable telescopic lengths. The supporting member includes two telescopic rods 6, and one end of the two telescopic rods 6 is respectively connected to the two telescopic plates 5, and the other end is respectively connected to the two clamping plates 4; the length of the two telescopic rods 6 can be locked to respectively limit the telescopic lengths of the corresponding telescopic plates 5.

[0028] The telescopic rod 6 includes a threaded rod 603, a main rod 601, a cavity and a knob cap 602. The first end of the main rod 601 is hinged to the corresponding clamping plate 4, and the knob cap 602 is rotatably connected to the second end of the main rod 601. The cavity is opened at the second end of the main rod 601 for the threaded rod 603 to be inserted through the knob cap 602. The first end of the threaded rod 603 is hinged to the bottom of the corresponding telescopic plate 5, and the second end of the threaded rod 603 is screwed to the knob cap 602.

[0029] Specifically, Figure 2 As shown, the lower part of the card plate 4 is fixedly connected to a base (not shown in the figure), and the first end of the main rod 601 is hinged to the base to achieve hinged connection with the card plate 4, and the bottom of the telescopic plate 5 is fixedly connected to a top seat (not shown in the figure), and the first end of the threaded rod 603 is hinged to the top seat to achieve hinged connection with the telescopic plate 5;

[0030] Furthermore, in this embodiment, a receiving cavity for receiving the telescopic plate 5 is provided at the first end of the shield plate 3, and the telescopic plate 5 can be telescopically adjusted along the receiving cavity, thereby adjusting the length of the telescopic plate 5 extending out of the receiving cavity (i.e., the telescopic length);

[0031] The two telescopic rods 6 can provide supporting force for the two telescopic plates 5 respectively, thereby providing supporting force for the first end of the shield plate 3 to improve the load-bearing performance of the entire shield plate 3; and when the length of the telescopic rod 6 is adjusted, the telescopic length of the telescopic plate 5 will be adjusted, specifically: screwing the knob cap 602, using the thread to drive the threaded rod 603 to extend and retract, thereby adjusting the length of the telescopic rod 6, and then pushing the telescopic plate 5 to extend or retract the accommodating cavity, so that the protective device of the present invention can not only be suitable for the spacing requirements of different lengths between adjacent cantilevered I-beams 1, but also meet the support requirements.

[0032] Furthermore, when the protective device needs to be removed from between adjacent cantilever I-beams 1, the shield plate 3 can be pulled in a direction away from the cantilever I-beam 1 to remove the retaining plate 4 from the retaining groove 2, and the protective device can be removed from between adjacent cantilever I-beams 1, which is easy to use.
