Abstract
The utility model relates to a main keel for a ceiling in the field of building decoration, and the main keel comprises a right-angled C-shaped groove body; and two reinforcing circular arc grooves are formed on the outer side of the right-angled C-shaped groove body and protrude inwards. The main keel has the benefits that due to the adoption of the structural styles of the two reinforcing circular arc grooves, the bearing capacity and the compressive resistance of the main keel are enhanced, and the safety is higher.
Description
Technical field
The utility model relates to the architectural decoration field, specifically a kind of smallpox main joist.
Background technology
In the building decorating industry now, the used main joist of furred ceiling, structure is C shape, and its bearing capacity and compressive resistance are limited, and service life is of a specified duration, gently then can produce furred ceiling distortion, affects attractive in appearance, heavy then can produce furred ceiling and collapse.
Summary of the invention
The purpose of this utility model is the problem and shortage for above-mentioned existence, according to mechanics principle, provides a kind of high-bearing capacity smallpox aluminium extruded sections main joist.
The technical solution of the utility model is achieved in that a kind of smallpox main joist, comprises right angle C shape cell body, and the C shape cell body outside in described right angle is provided with two and strengthens arc groove, and two reinforcement arc grooves are projecting inward to groove.
The utility model is by being provided with two form of structure of strengthening arc groove, and its bearing capacity and compressive resistance strengthen, and safety is higher.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is lateral view of the present utility model.
The specific embodiment
Shown in Fig. 1-2, the utility model is a kind of smallpox main joist, comprises right angle C shape cell body 1, and it is projecting inward to groove that C shape cell body 1 outside, right angle is provided with 2, two reinforcements of two reinforcement arc grooves arc groove 2.
Claims (1)
