Description

  The present invention relates to a door configured by providing a surface panel on the surface of a door rod constructed by assembling aggregates on four sides.

  Generally, a door provided at an entrance such as a front door is configured to include a door rod made of aggregate and a surface panel bonded to both the front and back surfaces of the door rod. The aggregate has a flat plate-like substrate portion and a pair of parallel extending portions that are bent and extended so as to be parallel to each other from both sides of the substrate portion, and the substrate portion is along the prospective direction of the door. The door cage is constructed by assembling four rounds in the state. In this type of door, by interposing a heat insulating material between the aggregate and the surface panel, it is possible to prevent dew condensation from occurring at the peripheral portion of the panel even when a temperature difference occurs between the room and the outside. (For example, refer to Patent Document 1).

  By the way, in the door mentioned above, when a temperature difference arises between the room | chamber interior and the outdoor side, a difference will arise also in extension of a pair of parallel extension part. For this reason, for example, when a fire occurs in the room, the indoor side is in a high temperature state, while the outdoor side is maintained in a low temperature state, so the parallel extending portion located on the indoor side in the aggregate is located on the outdoor side. It will heat-extend greatly with respect to the parallel extension part. Here, since it is connected with the hinge provided in the several places between the door frame on the suspending side of a door, the influence of the thermal expansion which arises in the parallel extension part by the side of a room | chamber interior can be suppressed. However, on the door end side of the door, since only the central portion is coupled to the door frame via the door lock device, the upper end and the lower end are curved toward the outdoor side, and the door is A situation may occur in which the head is warped so as to be convex toward the inside. If the door is warped, there will be a gap between the door and the door frame, which will not only impair the airtightness and watertightness between the door and the door frame, but may also become a flame through-hole in the event of a fire. is there.

  In view of the above circumstances, an object of the present invention is to provide a door that can prevent the occurrence of warpage due to a temperature difference between an indoor space and an outdoor space.

  In order to achieve the above object, a door according to the present invention is a door configured by providing aggregates on four sides to form a door rod, and providing a panel on the surface of the door rod, at least the door of the door rod. The aggregate located first has a base plate portion along the prospective direction and a pair of parallel extending portions extending along the direction of finding from both sides of the base plate portion. Are a reinforcing substrate part arranged so as to cover the opening between the ends of the pair of parallel extending parts, and a pair of reinforcing elements arranged so as to be opposed to the parallel extending parts from both sides of the reinforcing substrate part, respectively. A reinforcing member having an extending portion is disposed, a heat insulating material is interposed between one of the parallel extending portions and the reinforcing extending portion facing each other, and the other parallel extending portion The reinforcing extension part is in direct contact with the reinforcing extension part. .

  According to the present invention, the rigidity against warpage is improved by the parallel extension of the aggregate and the reinforcement extension of the reinforcing member coming into contact with each other. In addition, since one of the parallel extending portion and the reinforcing extending portion facing each other is in contact with each other via a heat insulating material, the heat transfer between the two is reduced, and the heat of the portion disposed inside is reduced. Since the elongation is suppressed and the other between the parallel extending portion and the reinforcing extending portion is brought into direct contact with each other, heat transfer between the two becomes large. Accordingly, if the parallel extending portion and the reinforcing extending portion with the heat insulating material interposed are disposed so as to be on the high temperature side, the elongation on the high temperature side is suppressed, while the elongation on the low temperature side is promoted. It is possible to prevent a situation where the reinforcing member is warped.

  Further, the present invention is characterized in that in the door described above, a heat expansion material is interposed as the heat insulating material.

  According to this invention, the heat transfer between the parallel extension portion and the reinforcement extension portion is suppressed by the heat expansion material.

  Moreover, the present invention is characterized in that in the door described above, the aggregate is disposed between the pair of reinforcement extending portions.

  According to the present invention, the rigidity against the warp of the aggregate is improved by the reinforcing member. In addition, the temperature rise of the parallel extension portion with the heat insulating material interposed between the reinforcement extension portion is suppressed, while the temperature rise of the other parallel extension portion in direct contact with the reinforcement extension portion is promoted. As a result, the aggregate can be prevented from warping.

  In the door described above, the reinforcing extension portion of the reinforcing member is disposed so as to cover each outer surface with respect to the parallel extending portion of the aggregate. A heat insulating material is disposed on the reinforcing substrate portion so as to be interposed between the reinforcing substrate portion and an end surface of the parallel extending portion of the aggregate.

  According to this invention, heat transfer from the reinforcing substrate portion to the parallel extending portion of the aggregate can be suppressed by the heat insulating material attached to the reinforcing substrate portion.

  According to the present invention, the rigidity against warpage is improved by the parallel extension of the aggregate and the reinforcement extension of the reinforcing member coming into contact with each other. In addition, since one of the parallel extending portion and the reinforcing extending portion facing each other is in contact with each other via a heat insulating material, the heat transfer between the two is reduced, and the heat of the portion disposed inside is reduced. Since the elongation is suppressed and the other between the parallel extending portion and the reinforcing extending portion is brought into direct contact with each other, heat transfer between the two becomes large. Accordingly, if the parallel extending portion and the reinforcing extending portion with the heat insulating material interposed are disposed so as to be on the high temperature side, the elongation on the high temperature side is suppressed, while the elongation on the low temperature side is promoted. It is possible to prevent a situation where the reinforcing member is warped.

FIG. 3 is an enlarged sectional view taken along line AA in FIG. FIG. 4 is an exploded perspective view showing an aggregate and a reinforcing member located at the door tip of the door shown in FIG. 1.

Hereinafter, preferred embodiments of a door according to the present invention will be described in detail with reference to the accompanying drawings.
1 to 3 show a door according to an embodiment of the present invention. The door illustrated here is used for the entrance of a building, and includes a door frame 10 having a rectangular frame shape. The door rod 10 is constructed by assembling the upper aggregate 11, the lower aggregate 12, the door-end vertical aggregate 13, and the suspension source vertical aggregate 14 around the circumference. The door-end vertical aggregate 13 and the suspension base vertical aggregate 14 include the base plate portions 13a and 14a along the prospective direction, and a pair of parallel extending portions extending along the direction of finding from both sides of the base plate portions 13a and 14a, respectively. 13b, 13c, 14b, and 14c, and the openings between the parallel extending portions 13b, 13c, 14b, and 14c are connected to each other in a state of facing inward. These aggregates 13 and 14 are formed of a metal such as iron or stainless steel, for example. As is clear from the figure, the door-end vertical aggregate 13 located at the door-end of the door rod 10 has a substrate portion of the suspension-source vertical aggregate 14 whose dimension along the prospective direction of the substrate portion 13a is located at the origin. 14a has a width smaller than 14a, and the dimension along the direction in which the parallel extending portions 13b and 13c are found has a length greater than that of the parallel extending portions 14b and 14c of the suspension vertical aggregate 14. It is. Although not clearly shown in the figure, the upper aggregate 11 and the lower aggregate 12 are configured to have the same configuration as the suspending longitudinal aggregate 14.

  Further, a reinforcing member 20 is joined to the door-end vertical aggregate 13 located at the door end of the door rod 10. The reinforcing member 20 includes the reinforcing substrate portion 20a along the prospective direction, and a pair of reinforcing extending portions 20b and 20c extending along the direction of finding from both sides of the reinforcing substrate portion 20a, in the same manner as the vertical door aggregate 13. And is formed of iron or stainless steel. The reinforcing member 20 is configured such that the dimension along the prospective direction of the reinforcing substrate portion 20a has substantially the same width as the substrate portion 14a of the hanging vertical aggregate 14 located at the hanging origin, and the door-end vertical bone It is joined to the door-end vertical aggregate 13 so as to surround the outer periphery of the material 13.

  More specifically, as shown in FIG. 3, the reinforcement extending portions 20 b and 20 c are overlapped on the outer surfaces of the parallel extending portions 13 b and 13 c of the door-end vertical aggregate 13 and are extended in parallel. The reinforcing member 20 is joined to the door-end vertical aggregate 13 in a state where the opening between the tips of the portions 13b and 13c is covered by the reinforcing substrate portion 20a. As shown in FIGS. 3 and 4, the outer surface of the parallel extending portion (hereinafter referred to as “indoor parallel extending portion 13 c” when distinguished) arranged on the indoor side in the door-end vertical aggregate 13 and the reinforcing member 20 is in contact with an inner surface of a reinforcement extending portion (hereinafter referred to as “indoor reinforcement extending portion 20 c” for distinction) through a heating expansion material (heat insulating material) 30. On the other hand, the outer surface of the parallel extending portion (hereinafter referred to as “outdoor parallel extending portion 13b” when distinguished) and the reinforcing member 20 are arranged on the outdoor side of the door-side vertical aggregate 13 on the outdoor side. The inner surface of the reinforcement extending portion (hereinafter referred to as “outdoor reinforcement extending portion 20b” when distinguished) is directly brought into contact. Further, the heating expansion material 31 is attached to a position that is an outer surface with respect to the substrate portion 13a of the door-end vertical aggregate 13, and is heated to a position that is an inner surface with respect to the reinforcing substrate portion 20a of the reinforcing member 20. The expansion material 32 is affixed. Each of the heating expansion materials 30, 31, and 32 is formed of a resin material having heat insulation properties, and is disposed over the entire length of the door-end vertical aggregate 13 and the reinforcing member 20 along the longitudinal direction. The heat expansion material 32 affixed to the inner surface of the reinforcing substrate portion 20a is disposed so as to be interposed between the individual end surfaces of the parallel extending portions 13b and 13c in the aggregate 13.

  Note that reference numeral 20 d in FIG. 4 is a through hole formed in the reinforcing substrate portion 20 a of the reinforcing member 20 in order to allow the door-end locking device 40 to pass therethrough. Reference numeral 50 denotes a lock reinforcing material that covers the periphery of the door lock device 40 protruding from the reinforcing substrate portion 20a, and reference numeral 51 denotes a pair of upper and lower mounting brackets for attaching the lock reinforcing material 50 to the reinforcing substrate portion 20a. is there.

  As shown in FIG. 3, the door rod 10 having the above-described configuration forms a door by filling the inside of a frame with a core material 15 such as urethane or corrugated cardboard honeycomb and then providing panels 16 and 17 on the surface. Further, as described above, the door includes the indoor parallel extending portion 13c of the door-end vertical aggregate 13 and the indoor reinforcing extending portion 20c of the reinforcing member 20 that are in contact with each other via the heating expansion material 30. In such a state, the hinge 70 provided at a plurality of positions between the end surface on the suspension base side and the door frame 60 is supported so as to be rotatable about the hinge shaft 71 with respect to the door frame 60. In addition, the code | symbol 72 in a figure is the door-end cover provided in the end surface by the side of a door-end.

  According to the door configured as described above, since the door-end vertical aggregate 13 and the reinforcing member 20 are joined to each other, when the door-end vertical aggregate 13 is disposed alone at the door end In comparison, the rigidity at the door end side is greatly increased. Moreover, the indoor parallel extending portion 13 c of the door-end vertical aggregate 13 is in a state in which the surface on the indoor side is covered with the heating expansion material 30 and the indoor reinforcing extending portion 20 c of the reinforcing member 20. Further, a heating expansion material 32 is interposed between the inner surface of the reinforcing substrate portion 20a and the end surfaces of the parallel extending portions 13b and 13c in the aggregate 13. Therefore, for example, when a fire occurs and the indoor side becomes a high temperature state, the indoor reinforcing extension portion 20c of the reinforcing member 20 becomes a high temperature state, but the indoor parallel extension portion 13c is reinforced by the heating expansion material 32. Since heat transfer from the part 20a is suppressed, there is no possibility that the temperature rises to such an extent that the heat is greatly increased. Furthermore, since the outdoor reinforcement extending part 20b of the reinforcing member 20 is in direct contact with the outdoor parallel extending part 13b of the door-end vertical aggregate 13, the indoor reinforcing extending part 20c in a high temperature state is in contact. Heat is transmitted through the reinforcing substrate portion 20a and the outdoor reinforcing extension portion 20b, and thermal elongation is promoted. Accordingly, it is possible to prevent a situation in which warpage occurs in the door-end vertical aggregate 13 and the reinforcing member 20, and there is no possibility that a gap is generated between the door and the door frame 60.

  In the embodiment described above, the reinforcing extension portions 20b and 20c are superimposed on the outer surfaces of the parallel extension portions 13b and 13c of the door-end vertical aggregate 13, but the reinforcing member 20 The door end vertical aggregate 13 and the reinforcing member 20 may be brought into contact with each other such that the parallel extending portions 13b and 13c are superimposed on the outer surfaces of the reinforcing extending portions 20b and 20c. Further, although the reinforcing member 20 is provided only on the door-end vertical aggregate 13, the reinforcing members may be provided on the other aggregates 11, 12, and 14. The aggregate is not limited to one formed from iron or stainless steel, but one formed from aluminum may be applied.

  Furthermore, although the heating expansion material 30 is interposed as the heat insulating material between the indoor parallel extending portion 13c and the indoor reinforcing extending portion 20c, the outdoor parallel extending portion 13b and the outdoor reinforcing extending portion 20b A heat insulating material may be interposed between the indoor parallel extending portion 13c and the indoor reinforcing extending portion 20c. According to the door configured as described above, even when the outdoor side becomes hotter than the indoor side due to solar radiation, it is possible to prevent a situation in which the door is warped so as to be convex toward the outdoor side. become able to.
