Abstract

PROBLEM TO BE SOLVED: To provide a ceiling structure capable of making the wings of the ceiling narrow and simply applying it with a smaller number of part items. SOLUTION: A plural number of joists 3 are arranged in parallel to each other on the lower side of a ceiling backing 1 made of concrete or the like and both ends of the joists 3 are supported on joist bearers 4. The joists 3 are held horizontally using adjusting fixtures and rectangular parallelepiped elastic bodies 51, which are impregnated with a hardening type adhesive 52, are fitted between the joists 3 and the ceiling backing 2 with a certain pitch before the adhesive 52 is hardened. When the adhesive 52 hardens, the elastic bodies 51 become rigidity bodies and serve as adhesive fixing members 5 adhesively fixed the joists 3 to the ceiling backing 1. A ceiling backing board 7 is then stuck to the lower part of the joists 3. Because the adhesive fixing member 5 is used for supporting the joists 3, the ceiling wings can be made narrow. The adhesive fixing member 5 can be facilely fitted between the joists 3 and the ceiling backing 1 by compressing it. Fittings such as hangers can be dispensed with, the number of part items can be reduced and workability can be improved.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceiling structure constructed by arranging field edges supported by field edge supports below a ceiling surface of concrete or the like, and attaching a ceiling base plate to the lower surface thereof. It is a thing.

[0002]

2. Description of the Related Art Board-clad ceilings are widely used in buildings such as reinforced concrete structures and lightweight steel frame structures. In a board-clad ceiling, a large number of hanging bolts are hung at a constant interval from the ceiling base surface made of concrete, etc., and a hanger attached to the lower end of these hanging bolts supports a plurality of field rims, and the bottom side The structure is such that a large number of field edges arranged at regular intervals in the direction orthogonal to these are attached, and a board for a ceiling base is attached to the lower surface of these field edges.

[0003]

In such a suspended ceiling, a ceiling space of about 85 mm or more is required.

As a result, the ceiling height becomes lower by that amount, and the room below it becomes smaller. Further, since it is necessary to assemble a large number of metal fittings, the workability is not so good.

An object of the present invention is to propose a ceiling structure and a construction method therefor capable of solving such problems.

[0006]

In order to solve the above-mentioned problems, the ceiling structure of the present invention comprises a plurality of field rims arranged at a constant interval below the ceiling base surface made of concrete or the like. A field edge receiver that is arranged in a direction orthogonal to the field edge and supports these field edges, and an adhesive fixing member that adhesively fixes each of the field edges to the ceiling base surface, A ceiling base plate attached to the lower surface side of the field edge, and a porous elastic body impregnated with a curable adhesive is mounted between the field edge and the ceiling base surface as the adhesive fixing member and cured. The one that has been made is adopted.

Here, it is preferable that the porous elastic body is an open-cell body made of synthetic resin.

Further, the curable adhesive is preferably urethane foam resin.

In constructing a ceiling of this structure, the adhesive fixing member is filled between the field edge and the ceiling base surface before the curable adhesive impregnated therein is cured, Hold the field edge so that it is horizontal by using the asaster metal fitting to hold the edge horizontally, and remove the adjuster metal after the hardening adhesive of the adhesive fixing member has hardened. Is desirable.

In the ceiling structure and its construction method of the present invention, a porous elastic body is mounted between the field edge and the ceiling base surface. The elastic body is mounted in the uncured state of the curable adhesive impregnated therein. Therefore, even if the distance between the field edge and the ceiling ground surface varies depending on the location, the elastic body follows and compresses or expands, and the upper and lower sides are completely in close contact with the ceiling ground surface and the field edge. When the adhesive impregnated in the elastic body is hardened after mounting, the elastic body becomes a rigid body, and the field edge is bonded and fixed to the ceiling base surface.

Further, if the field rim is held horizontally by using the adjuster fitting, the construction becomes easy.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

1 and 2 show a ceiling structure to which the present invention is applied. In these drawings, 1 is a concrete ceiling ground surface, and 2 is a concrete wall surface. Below the ceiling base surface 1, the field edges 3 are arranged in parallel at a pitch of 450 mm, for example, at intervals of about 10 mm. As these field edges 3, for example, groove type lightweight steel frames can be used. The ends of these fields 3 are on the wall 2
It is supported by a field bridge 4 mounted horizontally on the surface of the. As the field receiver 4, for example, an L-shaped lightweight steel frame can be used.

Between the field edge 3 and the ceiling base surface 1,
The adhesive fixing member 5 is mounted at a pitch of about 600 mm to 1000 mm. The adhesive fixing member 5 has a rectangular parallelepiped porous elastic body 51 impregnated with a curable adhesive 52, and is mounted between these members 3 and 1 while the adhesive is uncured. It has been cured. It is desirable to use synthetic resin open-cell bodies as the porous elastic body. Further, it is desirable to use urethane foam resin as the curable adhesive. In this way, each field 3
Both ends are supported by the field bridge 4, and an intermediate portion is adhesively fixed to the ceiling base surface 1 side by an adhesive fixing member 5.

Each field edge 3 is arranged so that the opening side thereof faces upward, and the elastic body 51 forming the adhesive fixing member 5 is cured while being pushed into the inside of the field edge 3. There is. Therefore, the field edge 3 is firmly adhered and fixed to the ceiling ground surface 1.

A ceiling base board 7, for example, a plaster board is attached to the lower surface of the field edge 3 by using screws 6. Although not shown in the figure, this ceiling base board 7
A ceiling finishing board or the like is attached to the lower surface of the to form the ceiling surface.

In the construction of the ceiling having this structure, the field edge 3 is bonded and fixed to the ceiling base surface 1 so as to be horizontal as follows. That is, after the field edge receiver 4 is attached to the wall surface 2 so as to be horizontal, the field edge 3 is bridged between them. Along with this, the adhesive fixing member 5 in which the adhesive 52 is in an uncured state is mounted between the field edge 3 and the ceiling base surface 1 at a constant pitch. After that, as shown in FIG. 3, the adjuster metal fittings 8 are struck on the ceiling base surface 1 along the longitudinal side surfaces of the field edge 3 at a constant pitch, for example, a pitch of 1000 mm.

The adjuster fitting 8 is provided with a pin body 81 having a sharp tip and a nut member 82 screwed into a male screw portion formed on the outer peripheral surface of the head side thereof. After the tip of the pin body 81 is driven into the concrete ceiling ground surface 1, if the nut member 82 is turned, it moves up and down. Therefore, the nut member 82 is aligned with the position where the field edge 3 is horizontal, and the lower surface of the field edge 3 is supported by the nut member 82 at that position.

When the adhesive 52 of the adhesive fixing member 5 is hardened after the field edge 3 is held horizontally in this way, the adhesive fixing member 5 loses its elastic properties and becomes a rigid body, and the edge which is held horizontally is retained. 3 is firmly adhered and fixed to the ceiling base surface 1 side. After that, the adjuster metal fitting 8 is removed. After that, on the lower surface of the field edge 3, the board 7 for the ceiling base
Stretch out.

[0020]

As described above, in the ceiling structure of the present invention and the method of constructing the same, the side of the ceiling base surface is formed by using the adhesive fixing member made of an elastic body whose field edge is impregnated with the hardening adhesive. It is designed to be directly adhered and fixed to. Therefore, unlike the conventional suspended ceiling, the ceiling foot can be reduced to, for example, about 30 mm, and the ceiling height can be increased to widen the room.

Further, in the present invention, since the adhesive fixing member is used to support the field edge, various metal fittings such as a hanging metal fitting and a hanger for connecting the metal fitting to the field edge are not required as in the prior art. Therefore, the structure is simple and the workability is improved.

Further, since the adhesive fixing member has elastic properties before the adhesive is hardened, even if the distance between the field edge and the ceiling base surface varies depending on the location, it is compressed to this gap. Since it can be pushed in, dimensional control of the adhesive fixing member is not necessary, and the attaching work is easy.

In addition to this, since the field edge is adhesively fixed to the ceiling base surface via the adhesive fixing member, it is possible to prevent vibrations and the like on the ceiling base surface side from being directly transmitted to the field edge. There is also.
