Embodiment Construction

[0023] The present invention will be further described below in conjunction with the embodiments shown in the drawings.

[0024] One. The double-layer door frame structure is used to reserve deformation buffer space to effectively absorb wall deformation.

[0025] The existing door frames are all single-layer structures, and their main function is to support the door panel and also have a certain strengthening effect on the wall. Its deformation is restricted by the wall system and is easily deformed with the wall. Such as Figure 3-5 As shown, the door frame in the present invention is composed of an inner door frame 1, an outer door frame 2, and a bottom edge. The section of the inner door frame 1 is designed to be concave, and the section of the outer door frame 2 is designed to be convex. The protruding part of the outer door frame 2 is inserted into the groove of the inner door frame 1. The inner and outer door frames are fitted to form a double-layer door frame. The botto...

Abstract

The invention discloses an anti-extrusion deformation door, which comprises a door plate and a doorframe. The doorframe comprises an outer-layer doorframe and an inner-layer doorframe. The section of the inner-layer doorframe is sunken. The section of the outer-layer doorframe is raised. The raised part of the outer-layer doorframe is inserted into a groove of the inner-layer doorframe. A certaingap is reserved between the raised part of the outer-layer doorframe and the groove of the inner-layer doorframe. The inner-layer and outer-layer doorframes are embedded to form the double-layer doorframe, and are connected rigidly. The gap is reserved between the inner-layer and outer-layer doorframes, so that the door is ensured to be safely opened at a critical juncture after a disaster to ensure the smoothness of an escape way.

Description

Technical field [0001] The invention relates to a house door structure, which is a special structure door with excellent anti-extrusion deformation ability and can ensure the smooth passage of life in critical situations. Background technique [0002] In recent years, severe earthquakes, mudslides, fires, and other major disasters have continued in my country and around the world, causing huge losses in terms of economy and life safety. Analyze the various factors that cause losses. The strong, sudden, and unpredictable nature of natural disasters is the main culprit. However, excluding natural disasters, “man-made disasters” are also factors that cannot be ignored. The main reason for the death of residents in the earthquake is the extensive use of prefabricated panels in housing construction); unfavorable hazard monitoring (the residential area is not well located and is located in the area affected by mudslides); the construction site is not strictly controlled for fireworks a...
