Steel-structure door

Abstract

The invention provides a steel-structure door. The steel-structure door mainly comprises a door frame, steel plates and reinforcing ribs, and is characterized in that the diamond-shaped reinforcing ribs are arranged in the door frame, three layers of steel plates are mounted on the door frame fixedly, two layers of accommodating cavities are formed among the three layers of steel plates, and each accommodating cavity comprises an inner layer made of fireproof materials and an outer layer made of cold-proof materials. The steel-structure door is simple in structure, high in strength and better in fireproof, cold-proof and sound-proof effects by the aid of the three layers of steel plates and the materials thereof, thereby being suitable for popularization and use.

Description

technical field [0001] The invention relates to the technical field of building steel structures, in particular to a steel structure door. Background technique [0002] The doors of existing houses and buildings are mostly wooden doors. They are not only flammable, but also have low strength and poor insurance performance. Therefore, more and more people choose metal doors to replace traditional wooden doors. However, the metal doors of the prior art have many defects such as heavy weight, poor thermal insulation effect, unsatisfactory sound insulation effect, and easy deformation by external force, which cannot meet the requirements of customers. Contents of the invention [0003] The purpose of the present invention is to provide a steel structure door with good sound insulation performance, fireproof, coldproof and not easily deformed by external force. [0004] The technical solution of the present invention is: a steel structure door, which mainly includes a door fra...
