A fixing screw is installed on the fixed top plate. The laying frame is symmetrically provided with connecting channel steels with its vertical central axis as the center. A guide hole is provided on the connecting channel steel, and the guide hole is connected to the fixed screw. The fixed screw is threadedly connected with a first nut and a second nut. A U-shaped block is provided on the laying frame, and a mounting hole is provided on the U-shaped block. A mounting bolt is inserted in the mounting hole. The inner groove of the U-shaped block is clamped with the vertical plate of the connecting channel steel. The vertical plate of the connecting channel steel is clamped with a screw hole, and the screw hole is threadedly connected to the mounting bolt. The laying frame is provided with multiple laying grooves.

[0004] The laying frame for building HVAC installation realizes the adjustment and positioning of the horizontal installation position and the up and down lifting and lowering adjustment positioning of the laying frame, which improves the flexibility of the laying frame.
