Problems solved by technology

[0002] At present, in the domestic construction process, the butt joint operation of large-scale I-beams is generally carried out simply by using the traditional mode of hoisting, assembly, connection, and unhooking. The construction process requires experienced construction personnel to carry out carefully and repeatedly Fine-tuning and other operations, so there are disadvantages such as long time-consuming, difficult construction, difficult precision control, and long crane time

Embodiment Construction

[0019] In order to reduce the construction difficulty, improve the construction efficiency, and also to improve the butt joint accuracy in the construction process, the present invention pre-installs the auxiliary connector for connecting the two I-beams on one of the I-beams, and then uses the auxiliary connector to connect the other I-beams. The precise positioning of the I-beams enables fast docking of the I-beams.

[0020] see Figure 1 to Figure 3 , the large-scale I-beam butt joint operation construction method of the present invention comprises the following steps:

[0021] S1. Prepare docking items: prepare the two I-beams 10, 20 to be docked and the sheet-shaped auxiliary connectors 11-18 for connecting the two I-beams 10, 20, and accurately lay out the wires according to the design requirements. The positions of the connection holes are marked respectively on the two I-beams 10, 20 and the auxiliary connectors 11-18 and auxiliary connection holes are provided;

Abstract

The invention discloses a construction method for the butt joint operation for a large I-shape beam, which comprises the following steps of: precisely installing an auxiliary adapting piece for connecting two I-shape beams on one I-shape beam in advance; and then precisely positioning the other I-shape beam by the auxiliary adapting piece to carry out quick butt joint on the I-shape beams. Compared with the prior art, the construction method has the characteristics that the difficulty of high-altitude butt joint operation is effectively lowered, the precision of the butt joint operation is improved, and the hoisting time and the crane occupation time are reduced so as to perform the positive action on lowering the construction building cost and improving the construction building economy.

Description

technical field [0001] The invention belongs to the field of construction, and more specifically, the invention relates to a construction method for facilitating the butt joint operation of large-scale I-beams. Background technique [0002] At present, in the domestic construction process, the butt joint operation of large-scale I-beams is generally carried out simply by using the traditional mode of hoisting, assembly, connection, and unhooking. The construction process requires experienced construction personnel to carry out carefully and repeatedly Fine-tuning and other operations, so there are disadvantages such as long time-consuming, difficult construction, difficult precision control, and long crane time. [0003] In view of this, it is indeed necessary to provide a construction method for large-scale I-beam butt joint operation with low difficulty and high efficiency. Contents of the invention [0004] The object of the present invention is to provide a constructi...
