[0002] A cantilevered scaffold is a temporary auxiliary facility widely used in building construction, which is used to support construction personnel, tools and materials for high-altitude work. In the design of a cantilevered scaffold, a diagonal brace is one of the key components, which provides lateral stability and resists wind load. In order to ensure the safety and stability of the cantilevered scaffold, the diagonal brace needs to be welded and fixed.

[0003] However, in the existing welding construction of the diagonal brace of a cantilevered scaffold, a tower crane is usually used to hoist the diagonal brace, and then welding is performed in the air. This method has certain safety hazards. First, when the diagonal brace is hoisted, the workers need to perform welding operations in the air, which has a high safety risk. Second, since the diagonal brace is not completely fixed in place, the hoisting ropes of the tower crane and the diagonal brace may sway in the air, affecting the welding quality.

[0033] In order to make the above objectives, features and advantages of the present application more obvious and comprehensible, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0034] In the following description, a lot of specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without departing from the spirit of the present application, so the present application is not limited to the specific embodiments disclosed below.

[0035] Secondly, the "one embodiment" or "embodiment" referred to herein means that the specific features, structures or characteristics can be included in at least one implementation of the present application. "In one embodiment" appearing in different places in the specification does not mean the same embodiment, nor does it mean that the embodiment is mutually exclusive with other embodiments, alone or selectively.

[0036] Embodiment 1

[0037] Reference Figure 1 - Figure 5 For the first embodiment of the present application, the embodiment provides a node fixing device for the upper end of the cantilevered scaffold diagonal brace, which comprises a main body assembly 100 and a connection assembly 200. The main body assembly 100 comprises a main beam 101 and a diagonal brace 102. The main beam 101 is connected to one end of the diagonal brace 102, and the other end of the diagonal brace 102 is connected to a pre-buried steel plate on the ground. The main beam 101 and the diagonal brace 102 are conveniently and quickly connected through the connection assembly 200, so that the diagonal brace avoids the problem of being hoisted for welding during installation and welding. The device resources are wasted, the quality of the weld cannot be guaranteed, and there is also a safety hazard.

[0038] Specifically, the connecting assembly includes the first fastener 201, the second fastener 202, and the adjusting piece 203. The first fastener 201 connects the main beam 101 and the diagonal brace 102, so that the main beam 101 and the diagonal brace 102 have a relatively stable and fast connection relationship before welding, so that the crane can perform the next step after hoisting the diagonal brace 102, and does not need to be in the hoisted state all the time. The second fastener 202 is arranged on one side of the inner cavity of the first fastener 201 and is connected with the diagonal brace 102 and the first fastener 201 respectively. The second fastener 202 further keeps the connection between the diagonal brace 102 and the main beam 101 accurate in position and does not cause position deviation during welding work, thereby affecting the weld quality. The adjusting piece 203 is arranged on one side of the first fastener 201 and is connected with the diagonal brace 102. Through adjustment of the adjusting piece 203, the entire connecting assembly 200 can be matched with the direction in which the diagonal brace 102 needs to be installed after installation, so that the connecting assembly 200 can be conveniently and quickly installed during installation, and the installation position and direction are adjusted when the diagonal brace 102 needs to be installed.

[0039] In summary, through the connecting assembly 200, convenient and fast connection before welding is provided when the diagonal brace 102 and the main beam 101 of the cantilevered scaffold are installed, the problem that the diagonal brace 102 needs to be hoisted by the tower crane during the welding process in the existing installation is solved, so that the main beam 101 and the diagonal brace 102 form a relatively fast connection during welding, the accuracy of the welding operation is increased, the weld quality is guaranteed, the safety risk and the on-site construction difficulty of the welding operation are reduced, and the construction efficiency is improved.

[0040] Embodiment 2

[0041] With reference to Figure 1 - Figure 8 For the second embodiment of the application, the embodiment is based on the previous embodiment. Specifically, the first fastener 201 includes a fixed circular plate 201a and a fixed screw rod 201b. The fixed circular plate 201a and the fixed screw rod 201b are fixedly and weldingly connected, and the fixed circular plate 201a is threadedly connected with the screw hole in the slotted 101a of the side wall of the main beam 101 through the fixed screw rod 201b. That is, the entire first fastener 201 can be fastened and connected with the bottom of the main beam 101 by rotating.

[0042] Further, the adjusting member 203 comprises a rotating plate 203a, a connecting plate 203b and an extension rod 203c. The rotating plate 203a is arranged in the rotating groove 201a-1 of the side wall of the fixed circular plate 201a. The connecting plate 203b is fixedly connected with the bottom side wall of the rotating plate 203a. The extension rod 203c is fixedly connected with the other side of the rotating plate 203a. One end of the extension rod 203c is telescopically and movably connected with the extension groove 201a-2 on the same side of the rotating groove 201a-1 through the extension spring 203a-1. The rotating plate 203a can telescopically and rotatably move in the rotating groove 201a-1 of the fixed circular plate 201a. The connecting plate 203b arranged at an inclined angle can be rotated by 180 degrees to match the inclined brace 102 to be installed.

[0043] Further, the side wall of the extension rod 203c is provided with a limiting ring 203c-1. The side wall of the extension groove 201a-2 is provided with a first limiting groove 201a-3. The diameter of the first limiting groove 201a-3 is larger than that of the extension groove 201a-2. The first limiting groove 201a-3 is not in communication with the rotating groove 201a-1. The limiting ring 203c-1 moves in the first limiting groove 201a-3 and cannot be separated from the first limiting groove 201a-3. That is, the whole rotating plate 203a cannot be completely separated from the fixed circular plate 201a and can only telescopically move within a limited range.

[0044] Preferably, the inner side wall of the rotating groove 201a-1 is provided with a rotating protrusion 201a-1a. The rotating protrusion 201a-1a is connected with the clamping groove 203a-9 formed in the side wall of the rotating plate 203a. When the rotating plate 203a is not pulled out a certain distance, the rotation of the rotating plate 203a can drive the fixed circular plate 201a to realize the rotation connection with the main beam 101.

[0045] Preferably, the side wall of the rotating plate 203a is provided with a limiting strip 203a-2. The limiting strip 203a-2 is connected with the second limiting groove 201a-4 of the side wall of the rotating groove 201a-1. The second limiting groove 201a-4 is used to make the limiting strip 203a-2 unable to be separated from the rotating groove 201a-1. It should be noted that the second limiting groove 201a-4 makes the limiting strip 203a-2 unable to rotate when the rotating plate 203a is not pulled out. The limiting strip 203a-2 can be rotated only when it is pulled out a certain distance.

[0046] When installing and adjusting, first make the fixed circular plate 201a correspond to the slot 101a, and the operator operates by hand to make the connecting plate 203b drive the rotating plate 203a and then drive the fixed circular plate 201a and the fixed screw 201b rotate and tightly connect with the main beam 101. Since the rotating plate 203a is not pulled out at this time, that is, the rotating protrusion 201a-1a is connected with the clamping groove 203a-9 on the side wall of the rotating plate 203a at this time, so the rotation of the rotating plate 203a drives the fixed circular plate 201a;

[0047] When the connecting plate 203b needs to be adjusted and installed in a direction, continue to pull out the connecting plate 203b to make the rotating protrusion 201a-1a and the clamping groove 203a-9 disengage with each other, so that the rotating plate 203a itself rotates in the rotating groove 201a-1 to realize 180-degree rotation of the connecting plate 203b. After rotation, due to the action of the extension spring 203a-1, the rotating plate 203a will be retracted to the specified position in the rotating groove 201a-1, and the rotating protrusion 201a-1a will be re-clamped and engaged with the clamping groove 203a-9 at this time, so that the rotating plate 203a cannot be rotated, that is, the connecting plate 203b cannot be adjusted.

[0048] Further, the second fastener 202 includes an extension clamping block 202a, a pressing plate 202b, and a connecting rod 202c. The extension clamping block 202a is arranged in the pressure receiving groove 201a-5 on one side of the rotating groove 201a-1, and the extension clamping block 202a is connected with the connecting rod 202c. The pressing plate 202b is arranged in the inner cavity of the fixed circular plate 201a, and one side thereof is connected with the other end of the connecting rod 202c. The pressing plate 202b is provided with a protruding rod 202b-1 on one side thereof. The protruding rod 202b-1 protrudes from the side wall of the fixed circular plate 201a and is connected with the matching groove arranged on the side wall of the slot 101a, so that the rotating friction between the overall fixed circular plate 201a and the main beam 101 is increased, and the fastening is more tightened. When the diagonal brace 102 abuts against the extension clamping block 202a, the extension clamping block 202a is pushed to extend into the pressure receiving groove 201a-5, which further pushes the connecting rod 202c to push the pressing plate 202b, so that the protruding rod 202b-1 extends out of the groove;

[0049] It should be noted that in the initial state, the extension clamping block 202a slightly extends out of the pressure receiving groove 201a-5, that is, the protruding rod 202b-1 is in the slot in the fixed circular plate 201a in the initial state. Only when the diagonal brace 102 is installed, the protruding rod 202b-1 will extend out to work.

[0050] Preferably, the telescopic clamping block 202a side wall is provided with a clamping block 202a-1, one end of the clamping block 202a-1 is connected with the telescopic clamping block 202a side wall opening through a spring, the other end is connected with the clamping groove 102a of the side wall of the diagonal brace 102, and the depth of the entering end of the clamping groove 102a is less than that of the terminal end, that is, when the diagonal brace 102 is installed and docked, the shallower side of the clamping groove 102a on it first abuts against the clamping block 202a-1, so that the clamping block 202a-1 extrudes the spring, at this time the diagonal brace 102 can slide to the specified position, when the top of the diagonal brace 102 completely abuts against the bottom of the main beam 101, the clamping block 202a-1 enters the deeper end of the clamping groove 102a under the rebounding action of the spring, so that the diagonal brace 102 cannot drop down, providing upward supporting force, facilitating subsequent welding work.

[0051] Preferably, the telescopic clamping block 202a side wall is provided with a clamping block 202a-1, one end of the clamping block 202a-1 is connected with the telescopic clamping block 202a side wall opening through a spring, the other end is connected with the clamping groove 102a of the side wall of the diagonal brace 102, and the depth of the entering end of the clamping groove 102a is less than that of the terminal end, that is, when the diagonal brace 102 is installed and docked, the shallower side of the clamping groove 102a on it first abuts against the clamping block 202a-1, so that the clamping block 202a-1 extrudes the spring, at this time the diagonal brace 102 can slide to the specified position, when the top of the diagonal brace 102 completely abuts against the bottom of the main beam 101, the clamping block 202a-1 enters the deeper end of the clamping groove 102a under the rebounding action of the spring, so that the diagonal brace 102 cannot drop down, providing upward supporting force, facilitating subsequent welding work.

[0052] Further, the connecting plate 203b is fixedly connected with the diagonal brace 102 through the bolt 203b-1, completing the preliminary docking and fastening work.

[0053] It should be noted that the main beam 101 can be made of I-beam material, the diagonal brace 102 can be made of profile steel material, and the remaining structures are made of high-strength material commonly used in construction.

[0054] Preferably, after the docking and fastening are completed, welding can be used to provide safeguard measures for the preliminary work, at this time the welding work can be carried out without a tower crane, the diagonal brace 102 and the main beam 101 have a relatively stable connection, which can ensure the welding quality.

[0055] In summary, the first fastener 201 and the second fastener 202 work with each other, so that the diagonal brace 102 can be conveniently and tightly fastened to the main beam 101 to complete the preliminary installation and docking, and then the welding work with quality guarantee is carried out, at the same time, the adjusting member 203 can be provided to adjust the installation direction after the connecting assembly 200 is installed, without the need to be re-disassembled for use, improving the work efficiency and enabling the material to be repeatedly used in construction.
