Abstract

The utility model discloses a steel door leaf which comprises an inner panel, an outer panel and an inner rib adopting a rectangular frame structure. The inner panel and the outer panel are fixedly arranged on the inner rib to form a door leaf; strengthening pieces are respectively arranged on the inner rib in the positions corresponding to four corners of the door leaf; and the cross sides and the vertical sides of the inner rib are fixedly connected through the strengthening pieces. As the strengthening pieces can effectively increase the strength on the inner rib in the positions corresponding to the corners of the door leaf, the door leaf is firmer, the rigidity of the door is effectively improved, the door leaf is hard to generate deformation during the use process, and the service life of the door leaf is prolonged.

Description

The steel door door leaf

Technical field

The utility model relates to a kind of steel door door leaf.

Background technology

At present, steel door generally is a muscle panel construction in adopting, interior muscle adopts horizontal, vertical steel section bar welding to make usually, position while welding (being position, door leaf angle) is the lower position of door leaf intensity, after long-time the use, phenomenons such as corrosion also appear in commissure easily, cause the firm degree of door leaf to reduce, and anti-theft feature weakens; Simultaneously, door leaf angle intensity reduces, and also influences the integral rigidity of door leaf, and door leaf is in use deformed easily, causes outdoors that shape is lost shape, is not closed completely, the appearance of problems such as switch has abnormal sound, reduction in application life.

At above-mentioned deficiency, need existing steel door door leaf is improved, increase its firm degree, simultaneously, also can increase the integral rigidity of door, make it be difficult for deforming, prolong application life.

The utility model content

In view of this, the utility model provides a kind of steel door door leaf, and this door leaf is with respect to existing door leaf, and its intensity is higher, and strong shock resistance is not yielding, and longer service life.

Steel door door leaf of the present utility model, the interior muscle that comprises wainscot, outer panels and rectangular frame structure, in being fixedly set in, described wainscot and outer panels form door leaf on the muscle, the position corresponding with four angles of door leaf is respectively arranged with girth member on the described interior muscle, the horizontal edge and the vertical edge of muscle in girth member is fixedly connected.

Further, described girth member is L shaped steel plate, and L shaped steel plate is connected with interior muscle by welding or riveted way;

Further, described girth member is the triangle steel plate, and the triangle steel plate is connected with interior muscle by the mode of welding.

The beneficial effect of utility model: steel door door leaf of the present utility model, comprise muscle in wainscot, outer panels and the rectangle, in being fixedly set in, described wainscot and outer panels form door leaf on the muscle, the position corresponding with four angles of door leaf is respectively arranged with girth member on the described interior muscle, the horizontal edge and the vertical edge of muscle in girth member is fixedly connected, since in girth member can effectively increase on the muscle with the intensity of door leaf angle correspondence position, make door leaf more firm, and effectively raise the door rigidity, make it in use be difficult for deforming, prolong application life.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further described.

Accompanying drawing is a structural representation of the present utility model.

The specific embodiment

Accompanying drawing is a structural representation of the present utility model, as shown in the figure: the steel door door leaf of present embodiment, comprise wainscot 1, the interior muscle 3 of outer panels 2 and rectangular frame structure, in being fixedly set in, described wainscot 1 and outer panels 2 form door leaf on the muscle 3, the position corresponding with four angles of door leaf is welded with L shaped steel plate respectively on the described interior muscle 3, the horizontal edge 3a and the vertical edge 3b of muscle 3 in L shaped steel plate is welded on, since in girth member can effectively increase on the muscle with the intensity of door leaf angle correspondence position, make door leaf more firm, and effectively raise the door rigidity, make it in use be difficult for deforming, prolong application life, certainly, and the position of door leaf angle correspondence on the muscle in the steel plate of employing triangle steel plate or other shape is welded on as ribs, play the effect that connects horizontal edge and vertical edge, can realize the purpose of this utility model equally.

Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
