Embodiment Construction

[0011] Such as Figure 1-2 As mentioned above, the present invention includes a steel skeleton 1, a wooden outer panel 2, and an inner filler 3. The steel skeleton 1 is formed of two U-shaped steel materials rolled and welded by two steel plates to form a hollow skeleton. The steel skeleton 1 is filled with the inner filler 3, the inner filler 3 is a whole piece of perlite fireproof board, and the whole piece of perlite fireproof board is used to replace the fireproof board formed by splicing small pieces, which prevents the fireproof board formed by splicing small pieces. The upper part of the steel-wood composite door loses its fireproof and heat insulation performance due to the sinking of the board for a long time. The inner and outer surfaces of the steel skeleton 1 are provided with the wooden outer board 2. The side of the steel skeleton 1 is bounded by solid wood 4, so that the overall appearance of the steel-wood composite door is neat and tidy.

Abstract

The invention discloses a steel-wood composite door, comprising a steel framework, outer wooden boards, and an inner filler; and the steel framework is rolled and welded to be a hollow form by steel plates, wherein the inner part of the steel framework is filled with the inner filler, inner and outer surfaces of the steel framework are provided with outer wooden boards, and the side faces of the steel framework are coated by solid wood. The invention has the following characteristics that: by adopting the steel-wood composite door, the problems of lower level of a steel door and high cost of a wooden milling door are solved; the steel-wood composite door has the anti-theft and fireproof functions of the steel door as well as the high-level appearance of the wooden door; and furthermore, the steel-wood composite door is low in cost, good in market prospect and suitable for the industrialized production.

Description

technical field [0001] The invention relates to the field of door and window manufacturing, in particular to a steel-wood composite door. Background technique [0002] The pure steel doors used in existing buildings are of low grade and lack aesthetic feeling in appearance, while the wooden milled doors have the problem of high cost. Contents of the invention [0003] The object of the present invention is to overcome the above disadvantages and provide a steel-wood composite door. [0004] The technical solution adopted by the present invention to achieve the above purpose is: a steel-wood composite door, including a steel skeleton, a wooden outer panel, and an inner filler. The steel skeleton is rolled and welded into a hollow type by steel plates, and the The inner filler is provided with the wooden outer board on its inner and outer surfaces, and its side is bounded by solid wood. [0005] The inner filler is a whole piece of perlite fireproof board. [0006] Patter...
