Description

Metal door frame

The utility model relates to the door in house, particularly installs the doorframe of door leaf.

The doorframe of existing doorframe, particularly security door is for obtaining high strength, many employing cross sections are rectangle or L shaped hollow metal doorframe, and doorframe is made with slab material or heavy wall section bar, and metal consumption is big, seal is poor, the sound-insulating and heat-insulating effect is undesirable, and decorative effect is poor.

Given this, the purpose of this utility model is to provide a kind of intensity height, seal and ornamental preferred metal doorframe.

The utility model adopts thin metal sheet metal forming U-shaped muscle structure and hierarchic structure to strengthen doorframe bulk strength and rigidity, adopts weather strip to improve seal, adopts ornamental strip to improve ornamental its purpose that realizes.

Metal door frame of the present utility model (referring to accompanying drawing), be rectangular shaped as frame, comprise two columns (1,2) of hollow, the strut rail (3) that connects two columns upper end and the support (4) of lower end, the outer panel of above-mentioned column and strut rail (5) has the U-shaped muscle (6) that forms groove at external surface.Ornamental strip (7) is arranged in this groove, and the interior plate of column and strut rail has U-shaped muscle (10) and weather strip (12) in the groove that forms groove and the ladder (11) that at least one stage is arranged.

The peripheral plate of above-mentioned column (1,2) and strut rail (3) middle part be the opening along frame, is connected with the support (17) of the bar shaped of the section that takes the shape of the letter U on mouthful limit (15,16) of these opening both sides and the plate (18,19) of the batten shape that connects with support.

Above-mentioned ornamental strip (7) is with the groove buckle connects and the bottom surface is outside  shape or channel section.Interior all plates of above-mentioned column and strut rail have and are the skewback (8) of expanding shape.

Metal door frame of the present utility model has following advantage and effect.

One, the U-shaped muscle structure of outer panel, the U-shaped muscle and the hierarchic structure of interior plate, strengthen the column of hollow strip member and the strength and stiffness of strut rail, particularly overcome the hollow strip member extremely weak shortcoming of strength and stiffness in the vertical, improved the bulk strength and the rigidity of doorframe.Theftproof is good.And can corresponding reduction make energy consumption with material thickness, reduction metal consumption, reduction.

Two, the gasket structure in the interior plate groove can improve the seal of doorframe and door leaf, if install weather strip again additional between stepped surfaces and door leaf, can further improve the seal of door, thereby improves the sound-insulating heat-insulation property of door.

Three, the decorative strip structure in the outer panel groove can constitute colour band attractive in appearance, has fabulous decorative effect.

Below, use embodiment and accompanying drawing thereof again, the utility model is described in further detail.

Embodiment 1

A kind of metal door frame of the present utility model as shown in the figure, is made section bar with the metallic sheet stock moulding, cuts into two columns 1 and 2 and strut rail 3, support 4 welderings of the strut rail of column and upper end thereof and lower end is unified into the doorframe of rectangular shaped as frame with usual method.

The shape of cross section of above-mentioned column 1, column 2, strut rail 3 and measure-alike.Constitute by outer panel, side plate, peripheral plate, interior all plate one.Outer panel 5 middle parts have that to form its section of inner groovy along edge at external surface be the U-shaped muscle 6 of U-shaped, and buckle has and is friction tight ornamental strip 7 in this groove.Ornamental strip 7 can be selected the ornamental strip of colored aluminum  shape or channel section for use, and oral area is outwards embedded in the groove to inner bottom part.Thereby form  shape and color band along frame.Interior all plates of column and strut rail, promptly interior all plates of doorframe have the skewback 8 that is right after outer panel 5 and face plate 9 directly.Skewback 8 is outside expansion shape, and three skewbacks of two columns and strut rail form toroidal.The interior plate of two columns and strut rail, i.e. the interior plate of doorframe has to be bent to form U-shaped muscle 10 that its section of groove is a U-shaped and ladder 11, U-shaped muscle 10 both sides and to join with the end difference of facing plate 9 and interior plate directly 11 of interior all plates respectively.The oral area of the groove of U-shaped muscle is inside, is fitted with the weather strip 12 of rubber system in the groove, forms between doorframe and door leaf the  shape hermetically-sealed construction along frame.Ladder 11 may be molded at least one stage, and present embodiment is made three stages, and the ladder of two columns and strut rail forms the inside stairstepping toroidal of doorframe.In the middle part and U-shaped muscle 10 positions of ladder 11, form the door leaf position of equipped door leaf 13, behind equipped door leaf 13, can be in the door leaf position again along the equipped weather strip 14 of frame.The support 4 of above-mentioned two column lower ends weldering connection is the bar shaped that the section that Open Side Down takes the shape of the letter U.Reinforce the setting doorframe after answering adjustment during the weldering connection.

The peripheral plate of above-mentioned column and strut rail, promptly the middle part of doorframe peripheral plate is the opening along frame.When connecting with body of wall, this doorframe adopt 6 to be symmetry and to be distributed on draw bail on the two column peripheral plate.Each draw bail has the mouth limit 15 of the both sides of welding the above-mentioned opening of connection connection and 16 support 17, and support 17 is the inside channel section bar of oral area.The plate 18 and 19 of the batten shape of stretching out with the inboard outside doorframe is respectively arranged in the riveted joint of support 17 middle parts.With the door opening of doorframe and body of wall 20 when equipped, plate is bent into by exterior surface of wall is close to, and with iron nail with the plate stickfast on body of wall.Block powdering with outer wall material again, simultaneously support 4 is imbedded below the Horizon.Constitute the firm assembling of doorframe and door opening.
