DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an example of a ceiling structure and its construction method to which the present invention is applied will be described with reference to the drawings.
[0006]
(Ceiling structure)
1 and 2 are views showing a ceiling structure according to this example, and are cross-sectional views taken along planes orthogonal to each other. In these drawings, 1 is a concrete ceiling base surface (reference surface), and 2 is a concrete wall surface (reference surface). Below the ceiling base surface 1, the field edges 3 are arranged in parallel at a pitch of, for example, 450 mm at intervals of about 10 mm. These field edges 3 can use, for example, a groove-type lightweight steel frame. The ends of these field edges 3 are supported by field edge receivers 4 attached horizontally to the surface of the wall surface 2. For example, an L-shaped lightweight steel frame can be used for the field receiver 4.
[0007]
Adhesive fixing members 5 are mounted between the field edge 3 and the ceiling base surface 1 at a pitch of about 600 mm to 1000 mm. The adhesive fixing member 5 is formed by impregnating a rectangular parallelepiped porous elastic body 51 with a curable adhesive 52, and is mounted between these members 3 and 1 while the adhesive is uncured. It has been cured.
[0008]
As the porous elastic body, it is desirable to use an open-cell body made of synthetic resin. Moreover, it is desirable to use a urethane foam resin as the curable adhesive. As described above, each field edge 3 is supported at both ends by the field edge receiver 4, and an intermediate portion is adhesively fixed to the ceiling base surface 1 by the adhesive fixing member 5.
[0009]
Each field edge 3 is attached in a state in which the opening side faces upward, and is cured in a state in which the elastic body 51 constituting the adhesive fixing member 5 is pushed into the inside of the field edge. Therefore, the field edge 3 is firmly bonded and fixed to the ceiling base surface 1.
[0010]
A ceiling base board 7, for example, a plaster board, is attached to the lower surface of the field edge 3 using screws 6. A ceiling finish board or the like (not shown) is attached to the lower surface of the ceiling base board 7 to form a ceiling surface.
[0011]
Here, a spacer 10 is sandwiched between the ceiling base surface 1 and the field edge 3 at a predetermined interval. The spacer 10 is made of a styrene resin foam that is widely used as a heat insulating material generally called a styrofoam, and has, for example, a rectangular parallelepiped shape. The upper and lower surfaces 10 a and 10 b of each spacer 10 are bonded and fixed to both the ceiling base surface 1 and the field edge 3 by hot melt adhesive 12. Similarly, a spacer 11 is also bonded and fixed between the field receiver 4 and the ceiling base surface 1 by a hot melt adhesive 12.
[0012]
(Construction method)
In the construction of the ceiling having this configuration, the level of the field edge 3 is set as follows and temporarily fixed to the ceiling base surface 1. This procedure will be described. First, the spacer 11 is bonded and fixed to the corners of the ceiling base surface 1 and the wall surface 2 with a hot melt adhesive 12 at a predetermined interval. Using the spacers 11 as a contact, the edge receiver 4 is attached to the wall surface 2 so as to be horizontal at a position below the ceiling base surface 1 by a predetermined distance.
[0013]
Next, the field edge 3 is bridged between these field edge receivers 4. Further, a spacer 10 having a hot melt adhesive 12 applied to the upper and lower surfaces 10a, 10b is mounted between the field edge 3 and the ceiling base surface 1, and the field edge 3 is leveled and at the same time temporarily fixed. I do. The spacer 10 may be selected from those having various thicknesses prepared in advance, or may be a rod-like or plate-like styrene resin foam cut into a predetermined thickness using a cutter. By using the spacer 10 having an appropriate thickness according to the place of use, the level of the field edge 3 can be raised.
[0014]
After the leveling and temporary fixing of the field edge 3 are performed, 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. When the adhesive 52 of the adhesive fixing member 5 is cured, the adhesive fixing member 5 loses its elastic characteristics and becomes a rigid body, and forms a state in which the horizontal edge 3 is firmly fixed to the ceiling base surface 1. To do. Thereafter, the ceiling base board 7 is stretched on the lower surface of the field edge 3.
[0015]
If necessary, until the adhesive 52 is hardened, as shown in FIG. 3, the adjuster fitting 8 is placed on the ceiling along the side surface in the longitudinal direction of the field edge 3 at a constant pitch, for example, 1000 mm. It may be driven into the lower ground 1 and the field edge 3 may be held in a horizontal state.
[0016]
The adjuster fitting 8 includes 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 on the head side. After the pin body 81 is driven into the concrete ceiling base surface 1, the nut member 82 is turned and pressed against the lower surface of the field edge 3. As a result, the field edge is held in a horizontal state by each adjuster fitting 8. After the adhesive is cured, the adjuster fitting 8 is removed.
[0017]
Thus, in the ceiling construction method of this example, the contact of the field edge receiver 4 and the field edge 3 is made using the spacers 10 and 11 made of styrene resin foam having good workability that can be easily cut using a cutter or the like. , Leveling, or temporary fixing. Since the thicknesses of the spacers 10 and 11 can be easily adjusted on site, the leveling of the members can be easily performed.
[0018]
In addition, since the spacers 10 and 11 are bonded and fixed to the ceiling base surface and wall surface using a hot melt adhesive capable of instantaneously bonding, the leveling and temporary fixing operations using the spacers 10 and 11 are performed easily and in a short time. be able to.
[0019]
Further, after the leveling and temporary fixing, the spacers 10 and 11 are left without being removed, so that the removing operation is not necessary, and the workability is improved.
[0020]
【The invention's effect】
As described above, in the field edge construction method of the present invention, a spacer made of styrene resin foam is bonded and fixed between a member to be positioned and a reference surface with a hot melt adhesive, thereby Positioning, field edge leveling, temporary fixing, etc. are performed.
[0021]
Since the polystyrene resin foam has good processability by a cutter or the like, a spacer having a thickness required in the field can be easily prepared. Further, the spacer can be bonded and fixed in a short time by the hot melt adhesive. Therefore, the member positioning operation can be performed efficiently and easily.
