Novel steel wooden door frame

Abstract

The invention belongs to the field of wooden doors and in particular relates to a steel wooden door frame in which a steel plate is additionally arranged so that the door frame has higher strength. The steel wooden door frame comprises a door plate block step and a door frame base, which are vertical to each other, wherein a steel plate frame is arranged in the door frame base; and the door frame base is connected with the door plate block step by the steel plate frame. The steel wooden door frame has the beneficial effects that the steel plate frame is directly arranged in the door frame, the steel improves the overall strength and fire retardance of the door frame, and as the steel plate has very low expansion and contraction rate and does not have water absorption, the weather resistance of the door frame 5 is improved and contraction and expansion, with solar term change, of the door frame become slight, thus ensuring that the coated paint can not crack or warp; and the steel wooden door frame has a simple structure and is convenient to process and low in cost.

Description

technical field [0001] The invention belongs to the field of wooden doors, and in particular relates to a steel-wood door frame with higher strength by adding steel plates in the door frame. Background technique [0002] It is modern people's pursuit of quality of life to choose expensive solid wood for home decoration. However, solid wood has low strength, poor weather resistance, and lack of flame retardancy. Security risks. In households, solid wood doors and door frames are generally used in households. Traditional wooden door frames are generally made of a whole piece of stepped wood with veneer and then painted. The strength is low and the weather resistance is poor. For example, the solid wood door frame disclosed in Application Publication No. CN 102041948 A , at least one side of the door frame is provided with a groove, and a metal strip to prevent the deformation of the door frame is arranged in each groove. Its structure is complex, but it can only prevent the d...

[0002] It is modern people's pursuit of quality of life to choose expensive solid wood for home decoration. However, solid wood has low strength, poor weather resistance, and lack of flame retardancy. Security risks

In households, solid wood doors and door frames are generally used in households. Traditional wooden door frames are generally made of a whole piece of stepped wood with veneer and then painted. The strength is low and the weather resistance is poor. For example, the solid wood door frame disclosed in Application Publication No. CN 102041948 A , the door frame has a groove on at least one side, and a metal strip to prevent the deformation of the door frame is arranged in each groove. The structure is complex, but it can only prevent the door frame from partially deforming, and the strength is still not high, and the weather resistance is poor.
