Description

Technical Field

[0001] The present invention relates to a door body such as a steel door as a fitting.

Background Art

[0002] As also described in the following patent document, a metal door device as a fitting includes a vertically rectangular door frame 1 as shown in FIGS. 7 and 8, and a door body 2 that opens and closes an opening formed by the door frame 1.

Patent Document 1

[0003] The door body 2 is composed of a metal (typically steel) surface material 3 that forms the outer surface of the door body 2, a metal (typically steel) frame member (not shown), and a filling material (not shown) filled in the internal space of the door body 2.

[0004] The door frame 1 that houses the door body 2 is a four-sided frame formed in a vertically rectangular shape from an upper frame 10, a lower frame 11, a vertical frame 12 on the leading edge side of the door, and a vertical frame 13 on the trailing edge side of the door.

[0005] The filling material is a sound insulation material or a heat insulation material, and can be formed from, for example, calcium silicate board, rock wool, glass wool, lightweight foam concrete panel (ACL panel), gypsum board, fiber reinforced cement board, or one or a combination of other materials.

[0006] The door body 2 is rotatably supported by a hinge 25 provided at the trailing edge side portion to the vertical frame 13 on the trailing edge side of the door frame 1.

[0007] A handle 26 is provided at the leading edge side portion of the outdoor side finding surface (the first finding surface 200 of the first surface material 20) and the indoor side finding surface (the second finding surface of the second surface material 21) of the door body 2. In the figure, 27A is a keyhole provided on the outdoor side finding surface.

Summary of the Invention

Problems to be Solved by the Invention

[0008] The conventional door body 2 can be removed by detaching the hinge 25 from the door frame 1, but the door body 2 itself is assembled as an integral unit and cannot be disassembled.

[0009] And when deformation damage or rust occurs on the door body 2 due to aging deterioration or the like, replacement after removing it from the door frame 1 is necessary. However, when the construction location of the door device including the door body 2 is a tunnel or an underground structure, etc., because it is deep underground and the transportation route is narrow, manual transportation is basically used for loading and unloading.

[0010] Furthermore, depending on the weight of the fitting, it may be difficult to carry it into a residential elevator. In that case, since it is necessary to carry it manually up the stairs, heavy labor has occurred.

[0011] An object of the present invention is to solve the disadvantages of the above-mentioned conventional example, and to provide a fitting that can be disassembled and loaded and unloaded, so that it can be manually transported, and can also be loaded and unloaded by an elevator, which was difficult due to weight in the conventional (integral type).

Means for Solving the Problems

[0012] To achieve the above object, the present invention firstly arranges metal boxes as cassette boxes between the facing materials constituting the door body and removably houses them. , the metal box has unevenness formed thereon, and the unevenness of adjacent metal boxes engages with each other. Second, The metal box is filled with a sound insulation material or a heat insulation material such as glass wool inside. Third, The gist is that punched metal is used for the facing material, and the holes formed by the punched metal of the facing material are shielded by the metal box.

[0013] According to the present invention described in claim 1, the facing material constituting the door body and the metal box housed between this facing material can be disassembled and loaded and unloaded, so manual transportation is possible, and because it is a split type, it is also possible to load and unload by an elevator, which was difficult due to weight in the conventional (integral type).

[0014] Also, because it is a split type, it can also adapt to large-sized fittings.

[0015] Furthermore, by housing a metal box between the surface materials constituting the door body, the metal box can act as an aggregate to maintain the strength of the door body.

[0016] Also, The metal boxes form unevenness that can be engaged with each other, making the cassette shape a fitting type, which facilitates on-site loading work. Also, since it is a fitting type, dustproofness can be ensured.

[0017] Claim as described in 2 According to the present invention of claim, by filling the metal box with a soundproof material or a heat insulating material such as glass wool inside, soundproof performance or heat insulation performance can be easily added to the door body. Moreover, by housing the metal box, the soundproof material or the heat insulating material can be disposed inside the door body at the same time.

[0018] Claim as described in 3 According to the present invention of claim, since punched metal is used for the surface material, weight reduction is possible. Also, the window holes of the punched metal of the surface material (skin plate) are closed by the surface of the metal box disposed inside this part, so no gap is structurally generated, and the airtightness as a door body can be maintained.

Effect of the Invention

[0019] As described above, the fitting of the present invention can be carried in and out in a divided manner, so it can be manually transported and can also be carried in and out by an elevator, which was difficult due to weight in the conventional (integral type).

Embodiments for Carrying Out the Invention

[0021] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing one embodiment of the fitting of the present invention, and in the figure, 2 indicates a door body as the fitting.

[0022] The door body 2 is rotatably supported by a hinge 25 on the door frame 1 as described in FIG. 7 above. The surface material 3 of the door body 2 is composed of a first surface material bent into a predetermined shape and a second surface material combined therewith, and is formed by bending a stainless steel steel plate. When the two are combined, a flat rectangular hollow body is formed.

[0023] As described above, there is a gap between the front and back surface materials 3. In the present invention, metal boxes 4 are arranged as cassette boxes and detachably stored between the surface materials 3 constituting the door body 2 as a substitute for the aggregate.

[0024] For the surface material (skin plate) 3 of the door body 2, punched metal having window holes 6 by punching is used. The window holes 6 (punching shapes) of such punched metal can be variously selected, such as a honeycomb (hexagon) as shown in the figure, round holes, or other design shapes.

[0025] The surface material 3 of the door body 2 is composed of a first surface material bent into a predetermined shape and a second surface material combined therewith, and is formed by bending a stainless steel steel plate. When the two are combined, a flat rectangular hollow body is formed.

[0026] For the surface material (skin plate) 3 of the door body 2, punched metal having window holes 6 formed by punching is used. The window holes 6 (punching shapes) of such punched metal can be variously selected, such as honeycomb (hexagonal), round holes, or other design shapes as shown in the figure.

[0027] The metal box 4 is made of a stainless steel steel plate or a different metal material, which is the same material as the surface material 3, and is formed into a rectangular parallelepiped box body by bending, and is filled with a filler inside.

[0028] The filler packed in this metal box 4 is a sound insulation material or a heat insulation material, and is formed, for example, from calcium silicate board, rock wool, glass wool, lightweight cellular concrete panel (ACL panel), gypsum board, fiber reinforced cement board, or one or a combination of other ones.

[0029] The metal box 4 has a rectangular parallelepiped shape having a front end face 4a, a rear end face 4b, an upper bed face 4c, and a lower bed face 4d, and a plurality of these are accommodated in parallel without gaps inside the door body 2.

[0030] The metal boxes 4 can be arranged side by side horizontally or vertically between the surface materials 3. However, when the metal boxes 4 are stored horizontally, the length of the metal box 4, that is, the dimension between the front end face 4a and the rear end face 4b, is made to match the width between the leading edge side and the trailing edge side of the door body 2.

[0031] In addition, the metal box 4 is formed with unevenness 5 that can be engaged with each other along its length direction on the upper bed face 4c or the lower bed face 4d.

[0032] The unevenness 5 is formed by rail-shaped protrusions and fits by the mutual combination of the metal boxes 4 located in the upper and lower stages.

[0033] Figure 3 shows various patterns of the unevenness 5. In the case of a convex shape where one side is wider and the other is narrower (L > l) (pattern a), when both sides have the same width (L = l) (pattern b), in the case of a seal box fitting shape (pattern c), in the case of an inclined notch fitting with an inclination in the middle (pattern d), when the entire surface is inclined (pattern e), when only half is inclined (pattern f), etc., various selections are possible.

[0034] The metal box 4 is housed between the surface materials 3 through an opening formed on one side of the door body 2, and a plurality of metal boxes 4 are stacked. For the metal box 4 to be housed next with respect to the first housed metal box 4, one of the unevennesses 5 slides in as a substitute for the rail, and they fit together and are closely arranged.

[0035] In this way, all the metal boxes 4 are detachably housed between the surface materials 3 through an opening formed on one side of the door body 2, and the opening is closed with a plate or the like.

[0036] In this way, since the metal box 4 can be housed between the surface materials 3 of the door body 2 without a gap, the surface of the metal box 4 closes the window hole 6 of the surface material (skin plate) 3.

[0037] Note that by coloring the metal box 4, the color can be revealed from the window hole 6, and it is also possible to provide a design variation.
