JPH0791148A - Manufacture of fire-preventive, sound insulation door - Google Patents

Abstract

PURPOSE:To provide a fire-preventive door having improved sound isolation characteristics by a method wherein a fluid noncombustible material is poured into a door framed body comprising steel strength frame or wooden frame so as to be solidified therein to form a core material and a surface panel is mounted onto the core material. CONSTITUTION:A framed body 1 of a door is formed from a steel strength frame or wooden frame and an auxiliary member such as a grip member or the like is attached to the framed body 1, if required. Next, a fluid noncombustible material 7 such as shirasu balloon cement, into which expandable fibers are mixed, is placed into the body 1 and solidified to form a core material 2. And the material 7 is placed in such a manner that a gap is not produced in the strength frame and between the body 1 and the core material 2. Thereafter a surface panel is bonded onto the material 2 to form a door. By this method, a fire-preventive door having improved sound isolation characteristics can be manufactured efficiently.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a fireproof and soundproof door provided in a building, a house or the like.

[0002]

2. Description of the Related Art A door having a fireproof and soundproof function is provided with a non-combustible core material. A conventional method for manufacturing a fireproof and soundproof door will be described with reference to FIGS.

First, a conventional example of a steel door will be described with reference to FIGS.

An unnecessary portion of the core material 2 such as a fiber-mixed foamed cement board is formed so that the frame body 1 is constructed by welding a bridle having a U-shaped cross section into a rectangular shape, and the frame body 1 is fitted to the inner size of the frame body 1 ( (Indicated by diagonal lines in the figure)
Excise. The core material 2 is fitted into the frame body 1, and the core material 2
Process the surface of so as not to absorb liquid easily. An adhesive is applied to the surface of the core material 2 and the surface of the frame body 1, the surface material is adhered so as to cover the frame body 1 and the core material 2, and pressure processing is performed to complete a steel door.

A conventional fireproof wooden door will be described with reference to FIG.

Unnecessary portions (shown by diagonal lines in the figure) of the core material 2 such as a fiber-mixed foam cement plate are cut out so as to match the inner dimensions of the wooden frame 3 at the time of completion (FIG. 6 (A)). The core member 2 is provided with a notch 5 so as not to interfere with the auxiliary member 4 provided inside the frame body 3. The auxiliary member 4 is provided in the notch 5, and the frames 6 forming the frame 3 are bonded to the four sides of the core member 2 (FIGS. 6B and 6C). The surface of the core material 2 is processed so as not to absorb liquid easily, and an adhesive is applied to the surface of the core material 2 and the surface of the frame body 3 so that the surface material covers the core material 2 and the frame body 3. Glued and pressed to complete the fireproof wooden door.

[0007]

The conventional steel door,
In the fireproof wooden door, it is necessary to cut the core material in accordance with the frame body, which causes dust generation due to the cutting work and causes loss of the core material 2. Further, in the steel door, as shown in FIG. 5, the force bone of the frame 1 has a U-shaped cross section, so that a gap is created inside the force bone, and the sound insulation effect of the steel door is reduced. Furthermore,
The fireproof wooden door has a problem in that the number of working steps is increased, the processing of the core material 2 is complicated, and the loss portion of the core material is increased.

In view of the above situation, the present invention aims to provide a method for manufacturing a fireproof and soundproof door which prevents dust from being produced, is simple to manufacture, and has a low manufacturing cost.

[0009]

SUMMARY OF THE INVENTION The present invention is characterized in that a fluid incombustible material is filled in a door frame body and solidified to form a core material, and a surface panel is attached to the core material. .

[0010]

Since the door frame is used as a frame for forming the core material, there is no need to process the core material for fitting the core material to the door frame, workability is improved, and various door frame bodies are provided. Will be applicable to.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

First, a method of manufacturing a steel door will be described with reference to FIG.

Cement 7 before being solidified is poured into a frame 1 made of a brisk having a U-shaped cross section, and the inside of the frame 1 is filled and solidified.
The core material 2 is formed. As the material of the cement 7, foamable fiber-containing silas balloon cement or the like is used.

The surface of the formed core material 2 is smoothed, the surface is processed so as not to easily absorb the liquid, and the surface panel is adhered and pressed.

According to this method, as shown in FIG. 2, the cement 7 is also filled in the strength bone, and no gap is formed between the frame body 1 and the core material 2.

A method of manufacturing a fireproof wooden door will be described with reference to FIG.

The frame 3 is preassembled by the frame 6, and the necessary auxiliary material 4 is attached. The cement 7 before solidification is poured into the frame body 3 to fill the inside of the frame body 3 and solidify to form the core material 2. As a material for the cement 7, fiber-containing silas balloon cement or the like is used. The surface of the formed core material 2 is finished to be smooth, the surface is processed so as not to easily absorb the liquid, and the surface panel is adhered and pressure-bonded.

[0018]

As described above, according to the present invention, it is possible to easily cope with fireproof and soundproof doors of various shapes, generate less dust, improve workability, and reduce loss of core material. Since the cost can be reduced and the gap between the frame body and the core material can be eliminated, excellent effects such as improved sound insulation performance are exhibited.
