Description

Technical Field

[0001] The utility model belongs to the technical field of building construction auxiliary tools, and in particular relates to an adjustable and rotatable external frame steel plate mesh connecting piece. Background Art

[0002] At present, the common ground-type scaffolding and cantilever scaffolding use steel pipe + safety green net as the overall facade image of the external frame. The two are connected by binding wire. This practice has the following disadvantages: 1 Due to the limitations of workers' skills and sense of responsibility, some of the safety green nets may not be tied firmly after the erection is completed, resulting in falling and accumulation, affecting the overall facade image; 2 The green safety net is a flammable material with no rigidity. The large-scale use of this material on the external frame on site will increase the source of danger on site; 3 When the scaffolding and cantilever scaffolding steel plate net are on the ground, there is no fixed connection method, so when the scaffolding and cantilever scaffolding are on the ground, they are usually The scaffolding was not connected and fixed with steel plate mesh on a large scale; 4. The use of safety green nets on the external frame needs to consider various environmental factors such as weathering, fading, and wind damage. Partial replacement of green safety nets may be required during the process. After the external frame is dismantled, most of the safety green nets are contaminated and cannot be used in circulation. Both of the above situations will cause material waste; 5. The use of steel pipes + safety green nets for the facade construction process requires the cooperation of multiple people, and the overlapping parts of the safety green nets need to be repeatedly tied, resulting in low construction efficiency, high requirements for the working surface, affecting the construction of other teams, and workers need to climb the external frame to tie the safety green net many times, increasing the risk of falling from high places. Therefore, compared with the conventional green safety nets that connect steel pipes by tying, the external frame steel plate mesh connector can conveniently, quickly and accurately position the steel plate mesh, so that it is firmly fixed on the internal steel pipe, without repeated tying on site, speeding up the construction progress, reducing the waste of resources and the breeding of dangerous sources, and improving the overall facade image. In addition, the steel plate mesh and connectors can be reused, which should be worthy of promotion and application in the field of scaffolding construction technology. Utility Model Content

[0003] The purpose of the utility model is to provide an adjustable and rotatable external frame steel plate mesh connector to solve the problem that the current conventional external frame uses steel pipes + safety green nets to be fixed together with binding wires, which may cause part of the green safety net to be loosely tied and fall off or pile up, affecting safety and the overall exterior image. If the safety green net is used as the exterior frame facade, the safety net may need to be replaced during weathering damage under long-term sun exposure conditions. After the external frame is dismantled, the green net may be exposed to the outside for a long time to form pollution and cannot be used any longer, causing waste. Ordinary scaffolding does not have a good fixing and connecting method for the steel plate mesh. During the fixing process of the external frame steel plate mesh, the overall exterior facade of the steel plate mesh needs to be vertically observed to avoid tilting of the overall exterior facade or excessive misalignment of details after the steel plate mesh is fixed. Therefore, if there is no efficient connection method during the erection of the steel plate mesh, more time and labor will be wasted, and technical problems such as rework may be caused due to misalignment of some details.
