Description

Technical Field

[0001] The utility model relates to the technical field of building components, in particular to a positioning error correction connecting piece for foundation embedded anchor bolts. Background Technique

[0002] The quality control of the foundation construction of the exported prefabricated structural system project is difficult, and the cost of dispatching domestic construction teams is high. At the same time, compared with the buildings constructed on-site, the prefabricated buildings have higher requirements for the positioning accuracy of the foundation embedded parts. When the quality level of foreign foundation construction teams is difficult to meet the requirements of the exported prefabricated structural system, high correction costs will be incurred and even disputes will arise.

[0003] From the perspective of precast foundations, the overall accuracy of steel foundations is relatively high, but the anti-corrosion treatment cost is relatively high. The self-weight of concrete foundations is too large, and the independent foundations that are easy to transport do not have integrity. The same problem of on-site positioning is involved, the transportation cost is high, and the problem of ensuring the installation accuracy of the foundation cannot be solved. Content of the Utility Model

[0004] The purpose of the utility model is to provide a positioning error correction connecting piece for foundation embedded anchor bolts to solve the above problems. The repositioning function of the anchor bolts is introduced in the design. Within the designed error range, the embedded anchor bolts on the foundation can be repositioned in an assembly manner without welding and wet operation, which not only solves the accuracy problem but also well controls the cost.

[0005] Technical Solution: The utility model provides a positioning error correction connecting piece for foundation embedded anchor bolts, including: a bottom connecting plate, stiffening ribs, and a top connecting plate. The bottom connecting plate is designed with a square structure, and there are several oblong holes on the bottom connecting plate, and a square hole is provided in the middle; the stiffening ribs include: longitudinal stiffening ribs and transverse stiffening ribs. The longitudinal stiffening ribs and the transverse stiffening ribs are designed in a cross shape and are arranged on the bottom connecting plate. The longitudinal stiffening ribs and the transverse stiffening ribs are aligned with the edges of the square hole; the top connecting plate is arranged above the stiffening ribs. The top connecting plate has the same structure as the bottom connecting plate. The relative angle between the top connecting plate and the bottom connecting plate is 90°. The oblong holes on the top connecting plate are orthogonal to the oblong holes on the bottom connecting plate. The orthogonal oblong holes provided on the bottom connecting plate and the top connecting plate can perform the first and second corrections, including translation corrections along the X and Y axes on the plane, which is convenient for subsequent assembly work.

[0006] Furthermore, for the above-mentioned positioning error correction connecting piece for foundation embedded anchor bolts, the bottom connecting plate, the stiffening ribs, and the top connecting plate are all connected by welding and are all made of steel plates, which improves the structural strength.

[0007] Further, in the above-mentioned positioning error correction connector for basic embedded anchor bolts, a precast foundation structure is connected below the bottom connecting plate.

[0008] Further, in the above-mentioned positioning error correction connector for basic embedded anchor bolts, the precast foundation structure includes: a precast foundation and a connector. The connector is arranged above the precast foundation. A steel plate mold plate is provided in the middle of the connector, and embedded anchor bolts are provided around the steel plate mold plate. When connecting to the bottom connecting plate, the positioning error of the precast foundation structure can be corrected within the design range through the length of the oblong holes.

[0009] Further, in the above-mentioned positioning error correction connector for basic embedded anchor bolts, the precast foundation is a quadrangular pyramid structure, and the connector is a cube structure. The precast foundation and the connector are integrally cast with concrete.

[0010] Further, in the above-mentioned positioning error correction connector for basic embedded anchor bolts, the number of the embedded anchor bolts is the same as the number of the oblong holes, and the positions where the embedded anchor bolts are arranged correspond to the positions of the oblong holes.

[0011] Further, in the above-mentioned positioning error correction connector for basic embedded anchor bolts, the size of the bottom connecting plate is slightly smaller than the size of the top surface of the connector.

[0012] Further, in the above-mentioned positioning error correction connector for basic embedded anchor bolts, anchor bolts are arranged in the oblong holes of the top connecting plate.

[0013] As can be seen from the above technical solutions, the present utility model has the following beneficial effects: In the positioning error correction connector for basic embedded anchor bolts of the present utility model, the bottom connecting plate and the top connecting plate have the same structure, oblong holes are arranged on them, and the oblong holes are orthogonally arranged to realize the translation of the anchor bolts in the X and Y axis directions. The positioning error of the precast foundation structure can be corrected within the design range through the length of the oblong holes. The stiffening ribs are arranged in a cross shape, which improves the connection strength, and is beneficial to export prefabricated projects, especially in the case where the on-site foundation construction lacks quality guarantee and on-site welding is not desired.
