[0002] In today's prefabricated composite slab construction system, the traditional cantilevered steel beam has the characteristic of requiring high positioning of the embedded parts of the cantilevered steel beam on the composite slab. Therefore, it has been replaced by the tie-rod type cantilevered steel beam. Compared with the fully cantilevered steel beam, the tie-rod type cantilevered steel beam does not need to consider the anchorage arrangement of the fully cantilevered steel beam on the floor slab, reducing many anchorage end intersection issues that need to be considered in the floor slab.
[0003] Currently, existing cantilever scaffolding is generally supported on cantilever steel beams. However, to fix the scaffolding to the steel beams, holes need to be drilled in the steel beams. Although this method can fix the position of the scaffolding, it is difficult to adjust the width of the fixed cantilever scaffolding. It needs to be dismantled again before the corresponding position can be adjusted. After the position is adjusted, holes need to be drilled again in the steel beams. This process is too cumbersome, and drilling too many holes will also affect the supporting strength of the steel beams.
[0004] Therefore, it is necessary to provide a new disc-lock external scaffolding structure based on tie-rod cantilever steel beams to solve the above-mentioned technical problems. Utility Model Content

Detailed Implementation
[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0021] Please see Figures 1-4 ,in Figure 1A schematic diagram of a preferred embodiment of the disc-lock external scaffolding structure based on a tie-rod cantilever steel beam provided by this utility model; Figure 2 for Figure 1 The diagram shows the overall structure of the positioning structure. Figure 3 for Figure 1 A schematic diagram of the structural cross-section of the steel beam connecting the uprights; Figure 4 for Figure 1 The diagram shows a side view of the steel beam fixed to the floor slab. The disc-lock external scaffolding structure based on a tie-rod cantilever steel beam includes: a steel beam 2, one end of which is laterally fixed to the surface of the floor slab 7 via a fixing member 3; a support rod 1, which supports the bottom surface of the upper floor slab 7 and the top surface of the steel beam 2; and a reinforcing structure 4, which is fixed between the support rod 1 and the steel beam 2. The reinforcing structure 4 includes a first connecting member 41, a tie rod 42, and a second connecting member 43. The tie rod 42 has two... The first connecting member 41 and the second connecting member 43 are rotatably connected to the ends respectively, and the pull rod 42 is rotatably connected to the steel beam 2 and the support rod 1 respectively through the first connecting member 41 and the second connecting member 43; the positioning structure 5 is slidably connected to the side wall of the other end of the steel beam 2, and the positioning structure 5 includes a positioning frame 51, which is slidably connected to the side wall of the other end of the steel beam 2; the scaffolding 6 is fixed to the surface of the positioning frame 51 by bolts.
[0022] In the specific implementation process, such as Figure 1 , Figure 2 and Figure 3 As shown, the scaffolding 6 includes uprights 61, connector plates 62, and crossbars 63. The uprights 61 are fixed to the top surface of the positioning frame 51 by bolts. The connector plates 62 are fixed to the side wall of the uprights 61. The crossbars 63 are installed on the uprights 61 by inserting pins into the connector plates 62. The side wall of the support rod 1 is also fixed with the connector plates 62, and the support rod 1 and the uprights 61 are fixed together by the crossbars 63. This allows the uprights 61 and the positioning frame 51 to be fixed together by bolts, and the uprights 61 and the support rod 1 to be fixedly connected together by the crossbars 63, thereby strengthening the overall connection of the steel beam 2, the uprights 61, and the support rod 1.
[0023] In the specific implementation process, such as Figure 1 and Figure 4As shown, the two fixing members 3 are grouped together, and the bottom end of the support rod 1 is clamped and fixed to the surface of the steel beam 2 by the two fixing members 3. The second connecting member 43 is also clamped and fixed to the surface of the steel beam 2 by another group of fixing members 3. This makes it easier to fix the position of the support rod 1 and the second connecting member 43 by the fixing members 3, thereby avoiding drilling holes in the steel beam 2.
[0024] In the specific implementation process, such as Figure 1 and Figure 4 As shown, the positioning structure 5 further includes a connector 52, a telescopic rod 53, and a sliding groove 54. The connector 52 is fixed to the side wall of one end of the positioning frame 51. The two ends of the telescopic rod 53 are threaded to the connector 52. The sliding groove 54 is provided on the side wall of the positioning frame 51. The sliding groove 54 is in the shape of an "I" shape, corresponding to the shape of the cross section of the steel beam 2, and the size of the sliding groove 54 is larger than the size of the cross section of the steel beam 2. The two positioning frames 51 are connected together by the telescopic rod 53, and the distance between the positioning frames 51 can be adjusted by the telescopic rod 53. The side wall of the positioning frame 51 is provided with screw holes. This allows the positioning frame 51 to slide on the steel beam 2 through the sliding groove 54, and the distance between the two positioning frames 51 can be adjusted by the telescopic rod 53. The position can be restricted by bolts through the screw holes on the surface of the positioning frame 51.
[0025] The working principle of the disc-lock external scaffolding structure based on tie-rod cantilever steel beams provided by this utility model is as follows:
[0026] In use, the steel beam 2 is first placed horizontally on the floor slab 7, with one end of the steel beam 2 extending outwards. Then, the steel beam 2 is fixed to the floor slab 7 using a two-piece set of fixing members 3. The fixing members 3 also clamp and fix the positions of the second connecting member 43 and the support rod 1, allowing the fixing members 3 to simultaneously fix the positions of the steel beam 2, the second connecting member 43, and the support rod 1. Next, the positioning frame 51 slides into the extended end of the steel beam 2 through the sliding groove 54. Then, each end of the telescopic rod 53 is connected to a positioning frame 51 via the connector 52. Finally, the position between the two positioning frames 51 is adjusted using the telescopic rod 53 to support the steel beam 2. The scaffolding 6 is positioned at its width, and then the scaffolding 6 is erected on the positioning frame 51. The uprights 61 and the positioning frame 51 are threaded together with bolts, and the bolts abut against the side wall of the steel beam 2 through the bolt holes to restrict the position of the positioning frame 51. Then, the adjacent support rods 1 and the crossbars 63 are connected together. Then, the length of the tie rod 42 is adjusted, and one end of the tie rod 42 is inserted and fixed to the side wall of the support rod 1 through the first connector 41, so that the support rod 1 is supported and fixed together with the steel beam 2 through the tie rod 42, thereby strengthening the stability of the support rod 1 and the uprights 61. This structure has the advantage of not needing to drill holes in the steel beam 2 and facilitating the adjustment of the cantilever width.

Simultaneously, two sets of fixing members 3 clamp and fix one end of the reinforcing structure 4 and the bottom end of the support rod 1 to the surface of one end of the steel beam 2. The positioning structure 5 is then slid into the extended end of the steel beam 2, and the spacing between the positioning structures 5 is adjusted using the telescopic rod 53, ensuring that the spacing of the positioning structures 5 corresponds to the width of the scaffolding 6. Then... The bottom end of the scaffold is fixed to the surface of the positioning structure 5 with bolts, and the bolts abut against the side wall of the steel beam 2 to restrict the position of the positioning structure 5. Then, the corresponding steel beam 2 is fixed at the same position on the upper floor slab 7, and the positioning structure 5 is also installed at one end of the steel beam 2.
