Description

Technical Field

[0001] The utility model belongs to the technical field of reinforcing bar insertion of building castings, and in particular relates to a reinforcing bar insertion positioning tool for a double T plate. Background Art

[0002] As a common component in the construction field, the prefabrication process of the traditional double T-plate is crucial to the quality of the component. During the prefabrication process, the double T-plate faces specific technical challenges due to its thin surface (usually only 4cm thick). This feature makes it particularly difficult to fix the dowels connected to the cast-in-place concrete on the surface of the plate. Specifically, due to the small diameter of the steel bars in the mesh, the binding and fixing between the dowels and the mesh becomes very unreliable. Therefore, during the pouring process, it is easy for the position of the dowels to shift due to the pressure and vibration of the concrete, further affecting the integrity and quality of the component.

[0003] In addition, once the dowel bar is displaced during the pouring process, the subsequent correction work becomes extremely complicated. In particular, when trying to correct the position of the dowel bar, sometimes it is necessary to pull it out and re-fix it. This not only increases the difficulty of construction, but may also cause additional damage to the components and even affect the overall safety of the building. Therefore, how to solve the problem of fixation and deviation of dowel bar in the production of double T-plates has become the key to improving component quality and construction efficiency. Utility Model Content

[0004] In view of the problem of fixing and deviating the inserted reinforcement in the casting production of the double T-plate in the background technology, the binding and fixing between the inserted reinforcement and the mesh becomes very unreliable, further affecting the integrity and quality of the component. In view of this, the utility model provides a double T-plate inserted reinforcement positioning tool.

[0008] As a further supplement to the above technical solution, two limit plates are provided on the L-shaped rod, and the two limit plates are arranged in parallel and parallel to the plane where the L-shaped rod is located, and the two limit plates and the bolts are distributed at the same end of the L-shaped rod, and the crossbeam and L-shaped pressure rod assembly are embedded between the two limit plates during the assembly process to prevent the L-shaped pressure rod assembly from rotating relative to the crossbeam.

[0009] As a further supplement to the above technical solution, L-shaped constraint plates are respectively arranged at both ends of the beam through bolts and nuts, and adjustment holes are arranged on the L-shaped constraint plates. The bolts and nuts install the L-shaped constraint plates on the beam through the mounting holes and the adjustment holes in sequence. The two L-shaped constraint plates are respectively tightly attached to the side edges at both ends of the mold to limit the left and right deviation of the beam.

[0010] As a further supplement to the above technical solution, the cross beams include two, and two longitudinal beams are arranged between the two, and multiple auxiliary cross links are arranged between the two longitudinal beams. The auxiliary cross links and the longitudinal beams are made of galvanized square steel pipes. Second positioning components corresponding to the first positioning components are arranged side by side and equidistantly on one side surface of the auxiliary cross links. Each group of the second positioning components includes two second upper clamping rods and two second lower clamping rods. The two second upper clamping rods are located directly above the two second lower clamping rods, and the two clamping distances are equal in the same horizontal direction. The inserted bars are respectively embedded between the two second upper clamping rods and the two second lower clamping rods for clamping and fixing.

[0014] Compared with the prior art, the utility model has the following advantages:

[0015] 1. The utility model introduces L-shaped pressure rod assemblies at both ends of the beam to form a clamp, and the dowel is clamped and fixed on the mold by each set of first positioning assemblies, which effectively solves the problem of dowel fixation and deviation in the production of double T-plates. This design ensures the stable clamping of the dowel on the mold, and can maintain the stability of the dowel position even under concrete pressure and vibration, thereby greatly improving the integrity and quality of the double T-plate casting components.

[0016] 2. The utility model realizes double limit constraint on the beam by setting two limit plates on the L-shaped rod and combining the L-shaped constraint plates at both ends of the beam. This double limit constraint design not only effectively prevents the beam from deflecting on the mold, but also further ensures the precise positioning of the inserted reinforcement, making the binding between the inserted reinforcement and the mesh more stable and reliable.

[0017] 3. The utility model forms a new dowel positioning tool by cleverly combining two cross beams, L-shaped pressure rod components, limit plates, two longitudinal beams and several auxiliary cross connecting rods, which can realize the synchronous positioning of all dowels of the double T-plate. This not only ensures the high quality of the double T-plate casting components, but also significantly improves the construction efficiency and brings great convenience to on-site operations.

[0018] 4. The utility model adopts a double embedded design of a limit plate and a positioning pin between the auxiliary cross link and the longitudinal beam. This assembly method can not only ensure the stability of the overall structure of the tooling, but also greatly facilitate the rapid assembly and disassembly work on site. Therefore, this design takes into account both the practicality of the tooling and the convenience of operation. BRIEF DESCRIPTION OF THE DRAWINGS
