Novel jointing construction between door or frame and wall panel of cabin

Abstract

The invention relates to a novel connection structure of a door, a frame and a bulkhead plate which is mainly used for the decoration, fireproof and living areas separation of various ships. The connection structure includes a door leaf (2), a bulkhead plate (10) and a doorframe (1). The connection structure is characterized in that the bulkhead plate (10) includes a surrounding wall (8), an indoor side decoration rotation plate (9) and an outdoor side decoration rotation plate (7); the transverse section of the indoor side decoration rotation plate (9) is a 'reversed L'-shaped structure and is arranged in the inner side of the surrounding wall (8); the transverse section of the outdoor side decoration rotation plate (7) is an 'L'-shaped structure and is arranged in the outer side of the surrounding wall (8); the doorframe (1) is manufactured into a standard size; the transverse section of the doorframe (1) is similar to a zigzag structure and consists of a middle 'I' frame (1.1), an outdoor frame (1.2) and an indoor frame (1.3); one side of the door leaf (2) is hinged with the middle 'I' frame(1.1) of the doorframe (1) by a gemel (5). The novel connection structure of a door, a frame and a bulkhead plate meets the wood thickness t2 by adjusting the thickness t1 of the indoor side decoration rotation plate and the thickness of the outdoor side decoration rotation plate, thereby realizing the size standardization of the thickness of the doorframe.

Description

technical field The invention relates to a novel connection structure of doors, frames and bulkhead panels, which is mainly used for decoration, fire prevention and partition of living areas of various ships. It belongs to the technical field of shipbuilding decoration. Background technique The connection structure of doors, frames and bulkhead panels for decoration, fire protection, and partition living areas of various ships in the past is shown in Figure 1. The thickness of the decorative board + the thickness of the outdoor decorative board) is produced on site, that is to say, the thickness and size of each door frame are different. The disadvantages of this production method are as follows: 1. The door frame needs to be manufactured and installed on site according to the actual size. The construction takes up a large area, takes a long time to make, low space utilization, low work efficiency, cumbersome work and easy to cause clutter on the construction site; 2. Af...

AI Technical Summary

Problems solved by technology

1. The door frame needs to be manufactured and installed on site according to the actual size. The construction takes up a large area, takes a long time to make, low space utilization, low work efficiency, cumbersome work and easy to cause clutter on the construction site;

2. After the door frame is installed, the gap between the door frame and the decorative plate should be treated with decorative angle iron. Not only is the installation complicated, but there will also be many welding seams and mounting screws

On the one hand, the welding gap needs to be coated with fireproof mud to meet the fireproof design requirements, resulting in a waste of manpower, material and financial resources, and direct welding is likely to cause deformation of the door frame, easy to be corroded, short service life, and affect fireproof performance; on the other hand, The mounting screws are exposed, which is not beautiful enough

3. The threshold is wide, which will affect the pedestrian traffic and cause the threshold to be stepped on.
