The invention discloses a hole reserved type suspended form device and a construction method thereof. By tight clamping of a pair of fixing components and a vertical pipeline, the two fixing components in mirror image arrangement clamp the hole reserved type pipeline requiring secondary concrete pouring, a connection rod sequentially penetrates a space between each pair of U-shaped hanging lugs and is matched with retaining structures and limiting nuts at two ends to realize fixed connection of the two fixing components, and accordingly close connection between the suspended form device and the vertical pipeline is realized. Due to bearing of upper secondary concrete pouring acting force under own rigidity and strength, excellent airtightness is achieved, cement slurry leakage is avoided, smoothness and cleanness of construction surfaces are guaranteed, construction quality is improved, and manual cleaning in a later period is avoided. Furthermore, construction suspended form requirements can be met, pre-embedding of materials is avoided, and damages of building structures are prevented. The hole reserved type suspended form device is recyclable, suitable for hole reserved construction of building floor plates in different sizes, simple in structure and flexible in arrangement and saves a great deal of construction measure cost.
