[0027] 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.

[0028] This utility model provides, for example Figure 1-9 The temporary protective device shown during the installation of a cantilever scaffold includes a rod 1, and also includes:

[0029] Fixing component 2 is located at the bottom of rod 1 and is used to fix the position of rod 1.

[0030] The protective component includes a vertical pole 3 set on the top of the fixed component 2, and a horizontal bar 4 set on the top of the vertical pole 3;

[0031] Connector 5 is installed at the connection between the upright 3 and the horizontal bar 4. Connector 5 is used to fix the position of the upright 3 and the horizontal bar 4.

[0032] It should be noted that both the uprights 3 and the crossbars 4 are made of plastic. In use, the pole 1 is fixed to the upright using the fixing component 2, and then the upright 3 is fixed to the pole 1. Finally, the upright 3 and the crossbar 4 are connected by the connector 5. Thus, the crossbar 4 and the upright 3 block one side of the I-beam, and the crossbar 4 and the upright 3 protect the workers during use.

[0033] Specifically, a connecting hole 101 is provided at the top of the rod 1, and the upright 3 is inserted and connected inside the connecting hole 101.

[0034] It should be noted that the rod 1 is a steel pipe with an outer diameter of 48mm and a wall thickness of 3.5mm. A connecting hole 101 is provided in the middle of the rod 1, so that the upright 3 can be inserted into the interior of the connecting hole 101. The bottom of the upright 3 is threaded, and the interior of the connecting hole 101 is also threaded. When it is necessary to fix the position of the upright 3, the bottom thread of the upright 3 is inserted into the interior of the connecting hole 101, and the position of the upright 3 is fixed by the engagement of the threads.

[0035] Furthermore, insert each upright 3 into the connecting hole 101 by 300mm. The length of the upright 3 above the upper layer of the I-beam is controlled to be 1200mm. After the upright 3 is installed, the verticality of each upright 3 is checked and calibrated.

[0036] Specifically, the fixing component 2 includes a second fixing rod 202 fixedly connected to the bottom end of the rod 1, a first fixing rod 201 fixedly connected to the back of the rod 1, a first clamp 203 for fixing the position of the first fixing rod 201 provided on the back of the first fixing rod 201, a second clamp 204 for fixing the position of the second fixing rod 202 provided on the back of the second fixing rod 202, and a limiting member 6 for restricting the rotation of the first fixing rod 201 provided at the connection between the first clamp 203 and the first fixing rod 201.

[0037] It should be noted that the rod 1 is fixed to the first fixed rod 201 and the second fixed rod 202 by welding, and the first clamp 203 and the second clamp 204 are respectively used to fix the positions of the first fixed rod 201 and the second fixed rod 202.

[0038] Furthermore, when fixing the position of rod 1, the worker is positioned one floor below the cantilever layer and sets up rod 1 along each longitudinal spacing of the outermost outer scaffold. Rod 1 is fixed to the outermost outer scaffold steel pipe by the first fixing rod 201, the second fixing rod 202, the first clamp 203, and the second clamp 204. The distance between the first clamp 203 and the second clamp 204 is controlled at 600mm, and the screws are tightened with a wrench. During the fixing of the position of rod 1, a laser level is used to calibrate while installing to ensure that the horizontality and verticality of rod 1 meet the requirements. At the same time, the intersection of the first fixing rod 201 and the second fixing rod 202 is controlled at 45 degrees. The joint of rod 1, the first fixing rod 201, and the second fixing rod 202 is connected by welding to form a solid whole, and the laser level is used to control that it is at the same horizontal height as each rod 1.

[0039] Specifically, the connector 5 includes a first connecting block 501 sleeved in the middle of the upright 3, with a first through hole on one side of the first connecting block 501, and the crossbar 4 inserted into the inside of the first through hole. The connector 5 also includes a second connecting block 502 sleeved in the middle of the upright 3, with second through holes symmetrically opened on both sides of the second connecting block 502, and the crossbar 4 inserted into the inside of the second through holes.

[0040] It should be noted that the first connecting block 501 is fitted onto the outermost upright 3, and the second connecting block 502 is located on the middle upright 3, used to connect the upright 3 and the crossbar 4.

[0041] Furthermore, after the uprights 3 are installed and aligned, the connectors 5 are slid in from the top of the upright 3. The connectors 5 are positioned when they are 600mm and 1000mm from the top of the I-beam. Their position is then fixed by adhesive or other means. Ensure that the connectors 5 on each upright 3 are at the same horizontal level. Insert the end of the crossbar 4 into the hole on the connector 5. During the installation of the crossbars 4, use a laser level to mark the lines for positioning, ensuring that each crossbar 4 is at the same horizontal level.

[0042] Specifically, the limiting component 6 includes a top plate 601 fixedly connected to the top of the first clamp 203, a limiting block 602 fixedly connected to the bottom of the top plate 601, a limiting groove 603 opened at the top of the first fixing rod 201, and the limiting block 602 inserted into the inside of the limiting groove 603.

[0043] It should be noted that the first clamp 203 consists of two blocks, bolts, and nuts. The top plate 601 is fixed to one of the blocks. When fixing the position of the first fixing rod 201, the two blocks of the first clamp 203 are first moved to the two sides of the first fixing rod 201, and the limiting block 602 at the bottom of the top plate 601 is inserted into the limiting groove 603 on the first fixing rod 201. When the first clamp 203 is fixed, the position of the top plate 601 and the limiting block 602 are fixed by the first clamp 203. The limiting block 602 restricts the position, preventing the first fixing rod 201 from rotating. This avoids the situation where the first fixing rod 201 drives the second fixing rod 202 to rotate when the second fixing rod 202 is installed.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
