Description

Technical Field

[0001] The utility model relates to the technical field of external frame installation, in particular to a novel external frame wall connecting piece used for PC external wall panels. Background Art

[0002] Wall ties are components that connect the scaffolding frame to the main structure of the building and transmit tension and pressure.

[0003] Wall ties play an important role in strengthening the overall stability of the scaffolding, improving its stable bearing capacity and avoiding major accidents such as tipping or collapse. Conventional wall ties include embedded sleeves and connecting fixtures. The more common wall ties for construction scaffolding are mostly steel pipes embedded in the structural side beams, and then one end of the wall tie rod is inserted into the steel pipe, and the other end is tied to the scaffolding through fasteners.

[0004] Conventional wall ties may not be able to adapt to special conditions when installed at PC external wall panels. For example, they cannot be installed when steel pipes cannot be pre-buried, which may cause problems such as local leakage of the structure. Utility Model Content

[0005] Based on the above-mentioned problems existing in the prior art, the purpose of the embodiments of the present application is to provide a new type of external frame wall connecting member for PC external wall panels, including a PC external wall panel, a main body, an embedded connecting plate, a perforated wall connecting rod, a plurality of bolts and an external scaffolding, wherein the main body is arranged on one side of the PC external wall panel, one side of the embedded connecting plate is connected to the main body, and the other side of the embedded connecting plate is connected to the perforated wall connecting rod by bolts, a steering fastener is provided at one end of the perforated wall connecting rod, and the external scaffolding frame is connected and fixed to the perforated wall connecting rod by the steering fastener.

[0006] Furthermore, the embedded connecting plate includes embedded tie bars, a plate body and a connecting end plate, wherein one end of the embedded tie bars is welded to one side of the plate body, and the connecting end plate is welded to the other side of the plate body.

[0007] Furthermore, the embedded reinforcement is welded by a perforation plug welding method.

[0008] Furthermore, the plate body is made of 6mm thick high-strength steel plate, the embedded reinforcing bar part uses three Φ10 steel bars, and the connecting end plate is provided with holes for connection and fixing.

[0009] Furthermore, the three steel bars of the pre-embedded reinforcement are distributed in a triangle.

[0010] Furthermore, the perforated wall connecting rods are made of conventional wall connecting steel pipes.

[0011] Compared with the prior art, the utility model has the following beneficial effects: less steel pipe material is used in terms of cost, a large amount of excavation and damage to the wall is avoided, the materials used are all conventional materials on the construction site, and waste steel bars and steel pipes can be recycled to a certain extent, reducing the overall cost;

[0012] In terms of quality, it can meet all the parameter requirements for connecting the constrained external frame, while avoiding large-scale excavation and damage to the main structure. It can effectively reduce quality problems such as leakage caused by repairing gaps in the wall connection parts after the construction is completed. BRIEF DESCRIPTION OF THE DRAWINGS
