ものであつた。 Conventionally, in order to manufacture a hollow steel plate door, a face plate that forms the door surface is welded to the front and back of a separately formed four-periphery frame, and a backbone that supports the face plate is welded inside the hollow part, or In addition to filling the core, attach a separately formed tongue piece for attaching the locking part to the locking side of the door.
In addition, the door had to be manufactured with a separately formed base for reinforcing the hinge part to withstand the hanging load of the hinge, which not only complicated the manufacturing process, but also made it consist of separate parts. This method requires a large number of structural members, and therefore has the disadvantage that it is not possible to simplify the manufacturing process and material management, and that the manufacturing process cannot be easily automated.

ものである。 The present invention has been devised based on a completely new concept in view of the above-mentioned actual situation, and its purpose is to provide a door facing surface on only one face plate side of a pair of front and rear face plates. In addition to integrally forming the tongue piece for attaching the lock part and the base for reinforcing the hinge on the hanging base side, a large number of studs are welded to the inner surface of one of the face plates, and the other face plate is formed on the above one face plate. After adhering or welding to the face plate, the other face plate and the stud are welded to form an integrated door, thereby significantly simplifying the structure of the hollow steel plate door and the manufacturing process thereof. We have developed a method for manufacturing steel plate doors that not only allows for the unification of component parts and simplifies material management, but also allows for easy automation of the manufacturing process and greatly improves production efficiency. This is what we are trying to provide.

An adhesive 37 is applied to each, and the other face plate 3 is butted against the four circumferential frame portions 6 and bonded. In this case, it goes without saying that welding may be used instead of the adhesive means. After adhering or welding the other face plate 3 to the four-periphery frame part 6 in this way, if this other face plate 3 and a large number of studs 5 are spot welded from the outside, the hollow steel plate door 1 is constructed. After that, all you have to do is weld the corners and sand them.

することができる。 In short, since the present invention consists of the steps described above, the steel plate door manufactured is
The four circumferential frame portions are integrally bent and formed on one face plate and bonded or welded to the other face plate, so when one face plate and the other face plate are butted together to form the prospective surface of the door, the other side The lock side facing piece and the hanging side facing piece of the face plate have a triple structure due to the folded parts provided on the locking side facing piece and the hanging side facing piece of one face plate, respectively, and the pair of front and rear face plates mentioned above has a large number of Because it is reinforced with studs, the overall strength can be dramatically increased, even though it is a hollow steel plate door. For this reason, not only is there no risk of the door twisting or becoming deformed even if it is exposed to wind pressure when opening or closing, but the hollow part is sealed, so it exhibits an excellent heat insulation effect. Can be done. For this reason, unlike conventional doors, there is no need to separately form the four-periphery frame using separate members, or to separately install a base for reinforcing the hinge on the hanging side of the door. Since the tongue piece for attaching the locking part is also integrally formed with one of the face plates, the structure of the door and the manufacturing process can be greatly simplified.
また、補強のために溶接される多数のスタツド

効果を奏するものである。 In addition, many studs that are welded for reinforcement are machined shaft-shaped parts, so even if the size of the door is different, if the thickness (estimated) of the hollow part is constant, the same standard products are used. It is also possible to simplify material management by unifying the component parts. Therefore, according to this manufacturing method, the manufacturing process of steel plate doors can be easily automated and the production efficiency can be significantly improved, which is an extremely useful practical effect.
