Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-3, a composite structure of a platformized stringer and an upper deck, has:
a floor body; the cross section of the longitudinal beam upper cover plate is of a groove shape, and the upper end of the longitudinal beam upper cover plate is connected with the floor body; the cross section of the longitudinal beam body is of a groove shape, the longitudinal beam upper cover plate can be inserted into the groove of the longitudinal beam body, and the longitudinal beam body is connected with the longitudinal beam upper cover plate. Through optimizing the lap joint form of longeron, upper cover plate and floor, the change of platform truck type floor height is realized to longeron upper cover plate cross-section height, and realizes that longeron body, floor body follow usefulness.
The two sides of the longitudinal beam upper cover plate are provided with slopes, and the two sides of the longitudinal beam body are provided with slopes matched with the slopes of the longitudinal beam upper cover plate. The longitudinal beam and the floor can be in a height-variable combined structure; through the different degree of depth welding of longeron upper cover plate at the longeron body, realize platform truck type floor altitude variation.
