Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a construction method for installing and positioning embedded bolts. Background Art

[0002] Embedded bolts are widely used in various construction projects, including buildings, bridges, steel structures, and equipment installation. To ensure the stability and accuracy of embedded bolts, their installation and welding must be performed with extreme precision. However, due to environmental factors and variations in operator precision, embedded bolts often deviate during installation. This not only affects project quality but can also lead to insecure installation and even create safety hazards.

[0003] Traditional positioning methods typically rely on manual calibration or crude templates, lacking precise positioning devices. Furthermore, during the welding process, the stability and accuracy of the weld position are often affected by factors such as temperature fluctuations and mechanical deformation. Existing positioning tools often rely on simple fixtures or manual alignment, which cannot meet the high-precision and high-efficiency requirements of large-scale construction. Summary of the Invention

[0004] The present invention aims to solve the above problems, thereby providing a construction method for installing and positioning embedded bolts.

[0005] The present invention solves the above problems by adopting the following technical solutions: A construction method for installing and positioning embedded bolts is carried out in the following steps: S1. Measure and lay out the lines on the surface of the concrete cap to determine the position of each bolt in the embedded bolt group; S2. Tie the pre-embedded bolt foundation steel mesh. The vertical steel bars of the pre-embedded bolt foundation steel mesh are longer than the height of the pre-embedded bolt foundation, and the tops of the vertical steel bars protrude out of the pre-embedded bolt foundation. S3. Weld a wire frame at the end of the vertical steel bar protruding from the top of the embedded bolt foundation. The wire frame is connected into a rectangle by horizontal and vertical bars arranged in a staggered manner. S4. A bolt positioning plate is installed on the top of the wire rack. Through holes are opened on the bolt positioning plate according to the positions of the bolts of the embedded bolt group. Nuts that match the embedded bolts are welded on the top surface of the bolt positioning plate and located at the through holes. S5. Install the embedded bolts from the bottom of the bolt positioning plate upwards, and screw the embedded bolts and nuts together until the top height reaches the designed elevation; S6. Support the formwork and pour the embedded bolt foundation to complete the installation and positioning of the embedded bolts.

[0006] Furthermore, while laying out the lines for measurement, the center point of the embedded bolt group is marked and a cross line is drawn. The intersection of the cross line and the center point of the embedded bolt group are located on the same vertical line. Saw cut marks are provided on the horizontal and vertical bars of the wire rack, and the saw cut marks are located directly above the branch lines of the cross line. The cross line and the saw cut marks provide a reference benchmark for the subsequent positioning and installation of the bolt positioning plate.

[0007] Furthermore, positioning notches are provided on the top surface of the bolt positioning plate and at the midpoints of the four sides, and the length direction of the positioning notches is perpendicular to the adjacent sides where they are located; the installation position of the bolt positioning plate can be adjusted quickly and accurately.

[0008] Furthermore, reinforcing bars are provided between the tops of the vertical steel bars of two adjacent embedded bolt foundation steel meshes, so that the entire embedded bolt foundation steel mesh structure forms a more stable whole, better resisting the external force and deformation generated during the construction process, ensuring that the embedded bolts remain stable during the construction process, and improving the firmness of the installation.

[0009] Compared with the prior art, the present invention adopting the above technical solution has the following outstanding features: Compared to traditional positioning methods that rely on manual calibration or rough templates, the method described in this paper effectively improves the accuracy of embedded bolt positioning through precise line measurement and standardized construction procedures, reduces installation deviations caused by environmental factors and differences in operating precision, and mitigates project quality risks. Compared to traditional positioning tools that rely on simple clamps or manual alignment, this method is more suitable for large-scale construction, improves construction efficiency to a certain extent, and helps meet the high-precision and high-efficiency requirements of engineering construction.
