Description

Technical Field

[0001] This invention relates to the field of prefabricated building technology, specifically an energy-saving photovoltaic curtain wall that is easy to adjust. Background Technology

[0002] In prefabricated building construction, the installation accuracy requirements between components are high. Taking the beam-column connection node as an example, the connection between the two is achieved by first installing the column and then aligning and installing the beam. Currently, the most common method is to hoist the beam to the installation position and then manually align and install it. However, due to the swaying of the hoisted beam and its own weight, it is difficult to achieve accurate alignment when aligning manually. Therefore, the technical requirements for hoisting equipment operators are high. When there is a small deviation during the installation process, it is impossible to correct the error through hoisting equipment. The beam height can only be adjusted by ground equipment, which is very inconvenient. Summary of the Invention

A fine-tuning base push plate is provided at one end that passes through the side wall of the crossbeam fine-tuning base, and the fine-tuning base push plate presses against the column.

[0009] In a preferred embodiment, the ends of the crossbeam fine-tuning screws on both sides of the crossbeam fine-tuning base are connected by a timing belt to achieve synchronous rotation.

[0010] In the preferred embodiment, the connecting flange at one end of the crossbeam is tightly attached to the side wall of the column. The upper and lower sides of the connecting flange are connected to the column through flange buckles. The length of the opening in the middle of the flange buckle is greater than the cross-sectional length of the column. A wedge-shaped top block is provided in the gap between the flange buckle and the column. The same top block adjusting screw is passed between the upper and lower wedge-shaped top blocks.

[0012] In a preferred embodiment, a fixing nut is welded to the smooth section in the middle of the adjusting screw.

[0013] The operation method for installing fine-tuning and calibration devices on components in prefabricated buildings, as described above, includes the following steps:

[0014] 1) The crossbeam fine-adjustment base is mounted on the top of the column, and the fine-adjustment base fixing knob is rotated to make the fine-adjustment base push plate press against the column, so as to achieve the fixed installation of the crossbeam fine-adjustment base on the column;

[0054] In the preferred embodiment, before performing step 1), two flange buckles 3 are pre-installed on the column 1. When manually aligning the crossbeam 2, after ensuring that the contact position between the crossbeam 2 and the column 1 is between the two flange buckles 3, the flange buckles 3 are fastened on the upper and lower sides of the connecting flange 201 of the crossbeam 2.

[0055] After completing the horizontal adjustment of the beam described in step 8), the beam 2 can be directly connected to the column 1 using the existing connection method.
