DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of constructing a steel door for use in an opening of a building such as a reinforcing steel bar, a reinforcing steel bar, and a steel frame concrete structure.

[0002]

There are various means for attaching a steel door to an opening of a reinforced concrete building or the like.
Although the construction method is taken, a frame is attached by either method,
The door is suspended from the frame, and adjustment between the frame and the door is achieved by adjusting hardware.

[0003] Conventional steel doors are manufactured in a factory, and it is impossible to adjust a frame or a door after the steel door is carried into a construction site, and it is necessary to adjust malfunctions with hardware such as locks and hinges. . Therefore, there is a problem that much labor is required for construction, there are many design restrictions, and a large number of stocks are required for each fine standard.

The present invention has been made to solve the above problems. The purpose is a steel door that is easy to fine-tune and has excellent workability by assembling the frame body according to the dimensions of the opening and door unit of the building's body on site without using the frame body assembled in advance. To propose a construction method.

[0005]

According to a first aspect of the present invention, there is provided a method of constructing a steel door, wherein an upper frame and a vertical frame constituting a steel door frame are attached to an opening of a building body. After the unit is hung, the vertical frame on the door end side is adjusted and attached to the door unit. According to a second aspect of the present invention, in the method for constructing a steel door, a decorative finding is attached to the periphery of the opening of the building vehicle and the frame of the steel door.

[0006]

1 and 2 show a building opening for mounting a steel door. A indicates the upper portion of the opening, and B indicates the side of the opening. Channel steel 3 for attaching the door frame fixed to the vehicle body 2 is disposed between the refractory bonds 1 and 1 made of plaster boards on the front and back. C indicates a lower portion of the opening, and a floor trimming material 5 is buried and arranged in a floor slab 4.

An upper frame 6 which forms a door frame in the opening.
1. Attach the hanging vertical frame 6-2 in order.

Each of the upper frame 6 and the hanging vertical frame 6 includes a steel frame structure 7 having a C-shaped cross section and a silicon rubber door rest 8 having a substantially square cross section on the surface thereof. The door contact section 8 includes the frame structure section 7
The frame 6 is fixedly bonded to the channel steel 3 by screwing a screw 10 through the L-shaped steel 9 through an L-shaped steel 9 fixed to the surface of the frame 6. In addition, a backup material 11 is filled between the end surface of the fireproof board 1 and the back surface of the frame structure 7 to close the gap.

The door unit 12 is suspended from the opening to which the upper frame 6-1 and the hanging vertical frame 6-2 are attached. A hinge is preferable as the hanging metal. As shown in FIG. 6, the door unit 12 is made of a steel plate on the front and back sides, and the door end 13 of the door stop is made of silicone rubber.

At the time of suspension, gaps a and b between the upper frame 6-1 and the floor slab 4 are adjusted. If the adjustment cannot be completed, the upper frame is reattached, and the liner is sandwiched between the channel steel 3 and the frame structure 7 for adjustment.

A vertical frame 6-3 is attached to the door of the suspended door unit 13. At this time, the gap c between the door edge 13 of the door unit 12 and the vertical frame 6-3, and the door unit 1
The degree of contact between the door tip of No. 2 and the door contact part 8 is adjusted. If necessary, the liner is inserted between the channel steel 3 and the door frame 6 and adjusted. Further, adjustment of the lock section such as the degree of latching and locking and the opening / closing speed of the self-closing device are adjusted.

After the upper frame 6-1, the hanging vertical frame 6-2, the door unit 13, and the door vertical frame 6-3 have been mounted, as shown in FIGS. The decorative find 14 is attached so as to cover the gap between the side edge and the frame 6. The decorative piece 14 is made of extruded silicone rubber, and is fixed with screws or an adhesive. An adjustment margin of the dimension e is provided in the width so that the width of the gap between the side edge of the refractory board 1 and the frame 6 can be changed.

In the above embodiment, the door contact portion 8 of the frame 6 or the flange 13 of the door unit 12 is made of silicone rubber.
Other flexible materials may be used. Flexible materials are preferred because they can be easily cut and the spacing can be finely adjusted. Silicon rubber, chloroprene rubber and the like are preferable because of their excellent heat resistance.

[0014]

The present invention has the above-mentioned configuration. This steel door construction method does not use a pre-assembled frame, but assembles the frame to the size of the opening at the construction site, so there are few design restrictions and it can handle various doors with few member standards it can. After hanging the door unit, adjust the gap between the door and the door vertical frame, and install it.
Compared with the conventional steel door construction method in which defects are adjusted with hardware such as locks and hinges, the method is easier and the burden on hardware can be reduced. Since the gap between the periphery of the opening of the building body and the frame is covered with decorations, mortar stuffing around the frame or board cloth finishing work etc. does not get caught, so it is only necessary to do it once after other work is completed. In this way, the carrying-in work, which has been conventionally divided into three times, can be summarized, and the carrying-in and construction work can be made more efficient. Defective parts can be replaced only by that part.
