Description

[Detailed explanation of the idea] This invention relates to the invention of a metal door.

The entrance doors of public housing are required by law to be fire resistant, and two types of doors are generally used.

One of them is a steel plate (usually 1.6 mm) as shown in Figure 7.
The door plate 1 has side edges 2, 2 formed on both sides by pressing, and the upper and lower frames 3, 3 are welded on the top and bottom (
Although the structure is simple and the price is low, the appearance is bad because the stile can be seen on the back side, and the sound insulation properties against noise are also poor.

The other type is a door (double-sided flush door) that combines two steel plates, front and back, and encloses glass wool as a core material to improve the appearance and sound insulation (double-sided flush door), but it is expensive and has a pattern on the door surface. There is a drawback that it is difficult to increase the number of types.

The present invention is based on the former single-sided press door, and aims to provide a metal door with an improved appearance at a relatively low cost by attaching a decorative board and a decorative edge to the root side of the back surface.

The present invention will be described below with reference to the illustrated embodiment. A single metal door plate 1 is pressed in the same manner as a conventional single-sided press door, and left and right side frames 2, 2 are formed on both side edges. The main body of the door is constructed by welding the upper and lower frames 3, 3 to the upper and lower ends.

3a is a closing plate for the upper and lower frames 3,3. Reference numeral 4 denotes a middle stile welded laterally to the vertical middle part of the root side of the door main body (the back side of a conventional single-sided press door), and the middle stile 4 has a round cross section with a web 4a and a flange 4b. None, above side frame 2
, 2 and the upper and lower frames 3, 3.

5, 5 is a decorative laminate support plate welded along the upper and lower webs 4a, 4a of the middle stile 4, and 5a is a flange thereof, and between the flange 5a and the flange 4b of the above-mentioned middle stile 4 is a decorative laminate support plate to be described later. It is formed to be able to insert and support the flange.

6 and 6' are fitted into the upper and lower recesses 7 and 7' partitioned by the middle stile 4 (i.e., the recess formed by the left and right side edge frames 2, 2, the upper and lower frames 3, 3, and the outer stile 4). This decorative board is provided with webs 6a on four sides, and a flange 6b is provided on the web facing the middle stile 4 to be inserted and supported between the flanges 4b and 5a of the above-mentioned middle stile and the support plate 5.

Reference numeral 8.8 is a decorative edge attached to the surface of the decorative boards 6, 6' by pot rivets 9. The decorative edge is formed so as to span the middle stile 4 and the peripheral stile, and can be of any shape. Adopted.

Reference numeral 10 denotes a reinforcing plate vertically welded to the center of the rear surface of the decorative panels 6, 6' in the horizontal direction; 11 a retaining piece welded to the door plate 1; a to hold the decorative plates 6, 6' through the reinforcing plate 10.

Reference numeral 12 designates an arbitrary number of decorative plate welding holes provided in the webs 3b of the upper and lower frames 3, 3.

Reference numeral 13 denotes a decorative pattern provided on the upper decorative board 6 by pressing, and any pattern can be adopted.

Reference numeral 14 indicates a welded portion between the decorative panels 6, 6' and the upper and lower frames 3, 3.

Reference numeral 15 indicates four reinforcing parts provided on the door plate 1 along the upper, lower, left, and right parts near the stile.

To install the above-mentioned decorative boards 6, 6', before assembling the closing plates 3a of the upper and lower frames 3, 3, fit the decorative boards 6, 6' into the upper and lower recesses 7, 7', and 6 and push up the lower decorative board 6' to attach each flange 6b to the above-mentioned middle stile 4.
and the flanges 4b and 5a of the decorative laminate support plate 5, the protruding piece 10a of the reinforcing plate 10 is engaged with the engaging piece 11, and the decorative laminates 6, 6 are inserted using the welding holes 12. ' web 6a and the upper and lower frames 3, 3 are welded.

After that, the closing plates 3a of the upper and lower frames 3 are assembled.

The metal door of the present invention uses the side with the decorative panels 6 and 6' attached as the front, and the presence of the decorative panels increases the sound insulation effect, and a core material is filled between the decorative panels and the door panel. By doing so, the sound insulation effect can be further increased, and since the decorative boards 6 and 6' are separated into upper and lower parts and are configured to be compact, the press mold can be small, and the decorative pattern 13 can be formed relatively easily by pressing. The pattern can be adopted.

Furthermore, since a decorative board and a decorative edge are attached, the door can be made more sophisticated, and by changing the design of the decorative edge and decorative pattern, a door with a different feel can be obtained.
