The embedded parts on the concrete columns or beams become very important construction quality control points. The position, construction method, convenience of construction and quality of the construction completion of the embedded part are key to control in the construction process. At present, the construction quality of many embedded parts in the building engineering is uneven, so that after concrete beams or columns are poured, the embedded parts are wrapped in concrete, the embedded parts are required to be found out in time, then redundant concrete covered on the embedded parts is crushed and cleaned, the embedded parts can be exposed, and subsequent construction and installation are carried out. The method not only increases extra workload and consumes a large amount of manpower, but also causes resource waste of building materials, and also causes great engineering quality hidden trouble under the condition that the position offset of individual embedded parts is larger.

At present, on many building sites, a traditional method is adopted for the construction of embedded parts, the embedded parts are welded on reinforcing steel bars, the edges of templates are aligned, when concrete is poured, the embedded parts are greatly deviated due to the deflection of the reinforcing steel bars, the quality is unstable, the embedded parts are completely wrapped by the concrete, and the embedded parts cannot be seen at all after the construction is completed.

The shape of the embedded part is not just a regular square plate-shaped part in the embodiment.

Referring to fig. 1-2, in this embodiment, the embedded part 2 is disposed at a reserved position (i.e., a designated position of a design drawing) of the concrete beam/column 1 by a positioning device, for example, an infrared positioning device (infrared positioning device), where the embedded part 2 is provided with claw parts 6 welded by using positioning steel bars 3, and the claw parts may be in various forms, and may be single or multiple rows, and in this embodiment, two rows and three columns of positioning steel bars (6 positioning steel bars) form claw parts, and the specific arrangement forms may be in a regular arrangement, for example, a rectangular array, or may also be in an irregular arrangement form. The lengths of the positioning steel bars can be equal in length or unequal in length, and the positioning steel bars can be placed in stirrups (stirrups of the concrete beam/column) by means of the stirrups. And the rear side of the embedded part is welded and fixed with a screw rod 4, the tail part of the screw rod is provided with a plug 5 for tightening and limiting, and an internal thread structure is arranged in the plug.
