[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned disadvantages of the prior art.

[0005] That is, the present invention relates to a door in which a head plate is fitted into a frame composed of a frame, a band, a bundle, and the like.
A hardened body is arranged on a thin portion of the four peripheral edges of the end plate, and at least one hard material is inserted from the frame to the end plate through the hardened body at least on one of the joining sides of the end plate and the frame. Features.

[0006] The hardened body is a porous hardened body mainly made of an inorganic material, for example, cement, calcium silicate,
It is a nonflammable material obtained by appropriately mixing various fiber materials, additives, and the like with one or more of inorganic powders such as gypsum and zonotolite, adding water as necessary, and kneading and forming the mixture.

[0007] Since air is kneaded into the cured product thus obtained at the time of kneading, the cured material is porous having fine gap particles therein.

[0008] Since the cured body is porous as described above, when the ambient temperature rises in the event of a fire, air expands in the interstices, causing stress in the crystal structure forming the material, and Impact resistance is reduced.

Therefore, in the event of a fire, the cured body can be easily destroyed by hitting and extinguishing the fire at the fire site.
Does not interfere with rescue operations.

[0010] Further, since the cured body is porous, it has a relatively small thermal conductivity, so that the rise in material temperature due to thermal power can be kept low for a long time, and the surrounding wood members are short. It is possible to prevent the temperature from significantly increasing in time and causing ignition. From this viewpoint, the thermal conductivity of the cured body is
It is preferably 0.4 Kcal / mh ° C or less.

Further, since the dimensional change rate of the hardened body is significantly smaller than that of the wood material, the dimensional change of the material at the four peripheral edges of the head plate can be suppressed, and a beautiful joined state can be maintained for a long period of time. .

It is preferable that the cured body is disposed at least as far as it can cover the decorative portion where the thickness of the mirror plate is reduced.

The end plate of the door according to the present invention is preferably such that a core made of the same wood material and a frame material made of a hardened body surrounding the core are sandwiched between the front and back members made of the wood material. Then, these are bonded and integrated. With this configuration, good adhesion between the front and back surface materials and the core material can be obtained, and a frame material made of a cured material having insufficient adhesion to the front and back surface materials because of a heterogeneous material. Since it can be restrained and fixed by the core material, the integrity of the whole end plate is improved.

At least one hard material is inserted from the frame to the end plate through at least one of the joining sides of the end plate and the frame through the cured body.

As the hard material, a material which is not easily broken by heat is used, and is preferably made of a metal material such as brass, iron and aluminum. The shape is arbitrary, and may be a pin shape, a small piece shape, a plate shape, or the like.

The hard material is bridged between the head plate and the frame,
Since these members are supported by the thick portion of the material, the hardened body inserted into the thin portion of the four peripheral edges of the end plate is reinforced, and the four peripheral portions of the end plate are prevented from disappearing and falling off in a fire. be able to.

The hard material is provided on at least one of the joining sides of the end plate and the frame, but may be provided on a plurality of sides.

Most of the hard material is buried in a hardened material having a low thermal conductivity. Therefore, even when a material having a high thermal conductivity is used as the hard material itself, the temperature of the hard material is remarkably high. It does not rise and there is almost no thermal effect on the surrounding wood members.

FIG. 1 shows an example of the construction of a door according to the present invention, in which a frame framed by left and right vertical frames 1, 1, upper and lower horizontal frames 2, 2, band 3, and upper and lower bundles 4, 4 has a mirror plate. 5, 5,... Are fitted.

Each member constituting the frame is made of plywood, fiberboard,
Wood chipboard, veneer laminate, laminated wood, solid wood, etc. can be used alone or in combination of two or more of these,
Further, it may be composed by combining with a different material such as an inorganic plate and a metal plate. Further, if necessary, a flame-retardant or non-combustible treatment may be applied. The surface is appropriately decorated.

The structure of the end plate 5 is shown in FIG. 2, and a rectangular core member 8 and a frame member 9 made of a hardened body surrounding the core member 8 are sandwiched between the front and back members 6 and 7. In this state, it is bonded and integrated.

Plywood, fiberboard,
Wood chipboard, veneer laminate, laminated wood, solid wood, etc. can be used alone or in combination of two or more of these,
Flame-retardant and non-combustible treatments may be applied as necessary. Also,
The surface is appropriately decorated.

Similarly, as the core material 8, plywood, fiberboard,
Wood chipboard, veneer laminate, laminated wood, solid wood, etc. can be used alone or in combination of two or more of these,
Flame-retardant and non-combustible treatments may be applied as necessary.

The core material 8 has a fiber direction of the front and back materials 6, 7
It is preferable to arrange so as to be orthogonal to the fiber direction, or to configure the core material 8 itself to have no orientation.
Thereby, deformation due to dimensional change such as warpage and twist of the head plate 5 itself can be suppressed.

As shown by the dotted lines in FIG. 1, pin-shaped hard members 14 and 14 are provided on the joining sides of the end plate 5 and the vertical frame 1 and the bundle 4.

At this time, if a colored coating similar to the door surface is applied to the protruding portion of the cured body 13, the door frame such as a frame to which it is fitted shrinks, and the coating layer on the door surface is formed. Even when a crack occurs in the base material, the base material of the cured body 13 is not exposed from the gap portion, and does not give an unsightly appearance.

FIG. 7 is a modification of the embodiment shown in FIGS. 2 and 3, and is an embodiment using square plate-shaped hard members 20 instead of the pin-shaped hard members 14. In the frame member 9 made of a cured body, through holes 21 and 21 for inserting the rectangular plate-shaped hard material 20 are formed, and in the core member 8, the through holes 21 protrude inward. The insertion holes 22 for receiving the distal end portion of the rectangular plate-shaped hard material 20 are formed.

[0032]

According to the present invention, by arranging a hardened body having a small thermal conductivity on a decorative portion of a head plate, which has been a weak point on a fire prevention surface, the heating rate of the decorative portion during a fire can be reduced. It is greatly reduced, and early ignition can be prevented.

Since the cured product is a porous material mainly composed of an inorganic material, air expansion occurs in the voids in the tissue with an increase in the ambient temperature during a fire, and the impact resistance is reduced. Therefore, the cured body can be easily broken by hitting, and quick fire extinguishing and rescue operations can be performed.

Further, with the hard material penetrating the hardened body,
Since it is bridged between the head plate and the frame and supported by the thick part of those members, the hardened body is sufficiently reinforced, and even if the fire is offensive during a fire, the four peripheral edges of the head plate are It does not disappear and fall off.
