Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of building engineering, especially a new type of scaffold wall connecting fastener for fabricated engineering. BACKGROUND

[0002] The scaffold wall connecting fastener plays a key role in the external protection scaffold system of building engineering and is an important component for ensuring the stability and safety of the scaffold, and its application involves multiple technical and structural aspects.

[0003] 1. Rigid connection technology: the rigid wall connecting piece is usually made of steel pipes, section steels and other materials.

[0004] 2. Flexible connection technology: the flexible wall connecting piece is mainly used in occasions with relatively low requirements for the stability of the scaffold, such as low-rise buildings or temporary simple scaffolds.

[0005] 3. Tension transmission technology: when the scaffold is subjected to outward tension, the wall connecting fastener should be able to effectively transmit the tension to the main structure of the building.

[0006] At present, manufacturers and construction parties have adopted various connection methods and fastener types to achieve effective application of the scaffold wall connecting fastener. In the fabricated structure building, the external wall is prefabricated in the factory and installed on site, and the prefabricated wall body needs to be installed at the beam position. In this case, the traditional method of embedding the tie-in point on the beam is difficult to implement because the embedding operation is limited by the installation process and structural characteristics of the prefabricated component.

[0007] However, the above-mentioned implementation still has the following problems: in terms of construction efficiency, the traditional embedded steel pipe method is complex, including the embedding, positioning, fixing of the steel pipe and the cutting treatment in the later stage, which consumes a lot of time and manpower. Even if the improved method of using a reserved tie-in hole is used, if the fastener design is unreasonable or the installation process is not optimized, it will also lead to slow installation speed and affect the overall construction progress. In terms of economic benefits, the embedded steel pipe in the traditional method cannot be recycled, causing waste of materials and increasing the cost of materials. At the same time, additional costs are generated due to the later plugging of the reserved hole, reducing economic benefits. In addition, if the fastener cannot be reused or the number of times of reuse is limited, it will also increase the long-term construction cost. In view of this problem, the present application proposes a new type of scaffold wall connecting fastener solution, which does not need to embed and cut the steel pipe, has high construction efficiency, and the fastener can be reused, which is convenient for construction and saves material cost, effectively improving the construction efficiency and economic benefits. CONTENT OF THE UTILITY MODEL

[0008] The utility model provides a new type of scaffold wall connecting fastener for fabricated engineering, solves the problem of complex process of traditional embedded steel pipe mode, including the embedding, positioning, fixing of steel pipe and cutting treatment in later period, etc.

[0009] To achieve the above object, the utility model discloses the following technical scheme:

[0010] A new type of scaffold wall connecting fastener for fabricated engineering, including the fastener body, the fastener body includes right angle fastener and rotating fastener, the right angle fastener and rotating fastener between the movable joint have the connecting column, this new type of scaffold wall connecting fastener for fabricated engineering still includes: the right angle fastener and rotating fastener swing joint, the right angle fastener upper surface is seted up with the clamping groove no.

[0011] Preferably, the screw rod two annular side surface thread sleeve has the nut one, and the screw rod two lower surface fixedly connected has the connecting shaft.

[0012] Preferably, the connecting shaft and the clamping groove no. 2 are rotatably connected, and the screw rod one annular side surface movable sleeve has the gasket and is threadedly connected with two nut two.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. The embedded steel pipe of the traditional scaffold wall connecting piece cannot be recycled, while the new type of fastener does not need to embed the steel pipe, greatly reducing the one-time investment cost of steel pipe materials. At the same time, the labor cost and material loss cost generated by the subsequent processing such as cutting after embedding the steel pipe are reduced. The new type of scaffold wall connecting fastener can be reused and can be recycled multiple times in multiple projects or different construction stages of the same project, improving the resource utilization rate of materials and reducing resource consumption.

[0015] 2. The scaffold wall connecting position and the formwork reinforcing bolt hole of the concrete cast-in-place part are designed simultaneously, and the draw hole reserved during formwork reinforcement is used as the fixing point of the wall connecting piece fastener. This avoids the traditional embedded steel pipe mode, reduces the additional damage to the wall structure and subsequent processing work. By increasing the screw rod eye on the new type of scaffold wall connecting fastener, the screw rod one is inserted, and then the nut two is used to tighten on the screw rod one. The double nut two increases the safety and stability of the connection, prevents the nut two from loosening during use, and ensures that the wall connecting fastener can withstand the load from the scaffold and reliably transmit it to the building structure.
