Description

Technical Field

[0001] The utility model relates to the technical field of floor drain construction, and more specifically to a one-time forming device for a floor drain slope on a cement mortar floor in a narrow space. Background Art

[0002] In the construction industry, particularly for mechanical and electrical installations in public facilities and commercial buildings, confined spaces like heating shafts and pipe shafts play a crucial role. These spaces typically house various pipeline systems, including heating, water supply and drainage, fire sprinklers, and power and low-voltage systems, and are essential infrastructure for ensuring the proper functioning of buildings. However, as modern architectural design trends towards efficient space utilization, the area reserved for these pipeline shafts has become extremely limited. In this context, heating shafts and pipe shafts often face the challenge of extremely compact layouts, with narrow interiors and densely packed, intertwined pipelines, greatly increasing the difficulty of construction and the complexity of subsequent maintenance.

[0003] Particularly noteworthy is the fact that the net width of these narrow spaces is generally less than 300 mm, posing a significant challenge to construction workers. Ground construction under such limited conditions, particularly when constructing drainage slopes, is difficult to implement using conventional construction tools and methods due to the limited space. This makes it difficult to achieve the desired standards for slope flatness, slope control, and drainage efficiency, significantly increasing the difficulty of quality control.

[0004] Therefore, how to efficiently and safely complete pipeline installation and ground construction in a limited space while ensuring the quality of the drainage slope has become a technical problem that needs to be solved urgently in current construction projects. Utility Model Content

The two ends of the movable strut are respectively connected to the connecting plate and the universal ball joint. An adjustment knob is provided on the movable strut.

[0010] The circular connecting plate adopts a slice-type structure.

[0011] The movable support rod and the connecting plate are connected by connecting pins.

[0012] The central column is provided with a plurality of holes at different levels, and the sliding sleeve is provided with positioning holes corresponding to the holes. The height of the sliding sleeve is fixed on the central column by a positioning pin.

[0013] The slope forming bevel knife includes a horizontal knife segment, a bevel knife segment and a column sleeve. The horizontal knife segment is arranged vertically with the central column. The column sleeve is arranged on the horizontal knife segment. The column sleeve adopts a bottom-opening and top-closed structure. The column sleeve is matched with the central column.
