Embodiment Construction
[0037] The following is attached Figure 1-3 The application is described in further detail.
[0038] The embodiment of the present application discloses a pre-embedded box without planting bars for secondary planting. refer to figure 1 , a pre-embedded box for secondary reinforcement without planting reinforcement includes a pre-embedded box 1, and a pre-embedded steel bar 2 is pierced on the pre-embedded box 1.
[0039] The pre-embedded box 1 is a U-shaped shell formed by integral bending of thin steel plates, which includes a bottom plate 11, and side plates 12 are bent and formed on both sides of the bottom plate 11, and the side plates 12 and the bottom plate 11 are perpendicular to each other; Protrusions 121 are respectively bent on the top, and the two protrusions 121 are set away from each other. The protrusions 121 can play an anchoring role, making the installation of the pre-embedded box 1 more stable. There are multiple rows of holes for installing the pre-embe...

The invention relates to a secondary steel bar planting-free embedded box and a construction method thereof, and belongs to the technical field of steel bar planting, the secondary steel bar planting-free embedded box comprises an embedded box body, the embedded box body comprises a bottom plate, the two sides of the bottom plate are bent to form side plates, a plurality of rows of embedded steel bars are arranged on the bottom plate in a penetrating mode, and the embedded steel bars are embedded in the bottom plate. The anchoring ends of the embedded steel bars are exposed out of the embedded box, and the lap joint ends of the embedded steel bars are bent in the embedded box. The connecting structure has the effect that the primary structure and the secondary structure are connected more firmly.
Description
technical field [0001] The present application relates to the field of implanting steel bars, in particular to a pre-embedded box for secondary planting without planting bars and a construction method thereof. Background technique [0002] When the primary structure and the secondary structure are poured separately, the formwork needs to be closed during the construction of the primary structure. The imported steel bars are overlapped with the steel bars in the secondary structure to realize the connection between the primary structure and the secondary structure. [0003] At present, the secondary rebar planting process requires eight processes, the process is cumbersome, each step is prone to problems, and the quality is difficult to control, resulting in insufficient connection between the primary structure and the secondary structure, and the long construction period due to the excessive amount of rebar planting , Low construction efficiency. [0004] In view of the ab...
