Abstract

PURPOSE:To heighten ceiling height, and to shorten the time for the execution of works by scaling down the space of the reverse side of a ceiling. CONSTITUTION:A wooden verandah running on the two sides of a building is fixed at a corner section formed by the top face 1 and side face 2 of a building body, a wooden receiving member 4 is fastened at the proper position of the top face 1, and a holding member 7 with a receiving port 7A holding one side edge of a ceiling board 6 is installed to the side face of the wooden verandah running on the two sides of the building. A joiner 5 with a receiving port 5A holding one side edge of the ceiling board 6 is mounted on the underside of the receiving member 4. The ceiling board 6 held between the joiners 5 and the joiner 5 and the holding member 7 is formed of a light-weight foam having flame resistance.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceiling plate mounting structure.

[0002]

2. Description of the Related Art In a conventional ceiling board mounting structure, a T-shaped rim is suspended from a top surface of a building body by a hanger, and the ceiling board is attached to the T-shaped rim suspended from the top surface. A plasterboard or the like is used as the ceiling board. There is also a ceiling structure made of vinyl chloride with a vinyl chloride sheet around the edges.

[0003]

A vinyl chloride sheet cannot be used when the interior restriction of the Building Standards Law specifies flame retardancy or higher. In addition, with the ceiling board mounting structure that uses the T-shaped rim, it takes time and labor to hang the T-shaped rim from the top surface with a hanger, and to attach the ceiling board to the T-shaped rim, which requires a long construction time. However, it was long and costly. Furthermore, since the T-shaped field rim is suspended by a hanger, the ceiling height becomes low.

Therefore, an object of the present invention is to provide a ceiling plate mounting structure which can reduce the space behind the ceiling to increase the ceiling height and shorten the construction time.

[0005]

In order to achieve the above-mentioned object, the present invention has a wooden edge fixed to a corner formed by the top and side surfaces of a building frame, and the wooden edge is appropriately positioned on the top surface. The receiving member is fixed, a holding member having a receiving opening for holding one side edge of the ceiling plate is attached to a side surface of the peripheral edge, and a joiner having a receiving opening for holding one side edge of the ceiling plate is attached to a lower surface of the receiving member, The ceiling plate sandwiched between the joiners or between the joiner and the sandwiching member is formed of a lightweight foam having flame retardancy.

[0006]

In the present invention, the construction is easy because the side edge of the ceiling plate is only sandwiched between the joiner and the sandwiching member. Further, since the joiner is attached to the wooden receiving member fixed to the top surface with a nail or the like, and the holding member is also attached to the peripheral edge of the wooden member, and the hanger is not used, the space above the ceiling can be reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, the top surface 1 and the side surface 2 of the building frame are shown.
A wooden peripheral edge 3 is fixed to a corner portion formed by and a wooden receiving member 4 is fixed to an appropriate position on the top surface 1. The surrounding edge 3 and the receiving member 4 are made of wood having a thickness of about 2 cm to 5 cm. When the building body is concrete, concrete nails, anchors or the like may be used as the fixing means to the building body. Several receiving members 4 fixed to the top surface 1 are provided at positions where a joiner 5 described later is arranged. The joiner 5 attached to the lower surface of the receiving member 4 is formed of flame-retardant vinyl chloride, and has a receiving port 5A for holding one side edge of the ceiling plate 6 on both sides (see FIG. 2). Also,
A receptacle 7 for holding one side edge of the ceiling plate 6 on the side surface of the peripheral edge 3
A holding member 7 having A is attached.

The holding member 7 is composed of two members as shown in FIG. That is, the edge receiving member 71 attached to the peripheral edge 3 and the edge member 7 attached to the edge receiving member 71.
2 and the engaging piece 71 formed on the edge receiving member 71.
A and the engaging piece 72A formed on the edge member 72 are engaged with each other, and the tip end side of the edge receiving member 71 and the tip end side of the edge member 72 form a receiving port 7A. The holding member 7 is also made of flame-retardant vinyl chloride.

The ceiling plate 6 is formed of a lightweight foam having flame retardancy. The size of the ceiling plate 6 is 90 × 360
A large version of about cm can be used. It is preferable to use Everlite Board (registered trademark) or the like as the flame-retardant foam.

To construct such a ceiling plate mounting structure, first, the receiving member 4 is fixed to the top surface 1 and the turning edge 3 is fixed to the corner portion formed by the top surface 1 and the side surface 2 (turning edge). 3 may be an existing one). Then, the joiner 5 is attached to the receiving member 4 according to the size of the ceiling plate 6. One side edge of the ceiling plate 6 is sandwiched between the one receiving edge 5A of the joiner 5 attached to the receiving member 4, the receiving edge 5A of another joiner 5 is inserted into the one side edge opposite to the one side edge, and then this joiner is inserted. 5 is attached to the receiving member 4. The ceiling plate 6 near the side surface 2 of the building frame has one side edge thereof sandwiched by the other receiving port 5A of the joiner 5, and the other side edge thereof is applied to the edge receiving member 71 and the edge member 72 is inserted from below to engage. The joint pieces 71A and 72A are engaged. In this state, the receiving port 7A holds one side edge of the ceiling plate 6. The number of joiners 5 also changes according to the size of the ceiling plate 6, and the number of receiving members 4 also changes.

If the ceiling plate 6 needs to be 2 m or more in length, a cut 61 is formed in the ceiling plate 6 substantially at the center in the lengthwise direction, and the ceiling plate 6 is bent from the cut portion 61 for transportation. You can It is also possible to bend the ceiling plate 6 in two and transport it, and return it to the original state for construction. A decorative surface 62 is formed on the surface side of the ceiling plate 6.

The holding member 7 and the joiner 5 are molded from flame-retardant vinyl chloride, but they may be molded from other materials as long as they are flame-retardant.

[0014]

As described above, according to the present invention, one side edge of the ceiling plate is held between the receiving ports of the joiner,
Since the joiner may be attached to the receiving member fixed to the top surface, the construction can be performed easily and quickly. Also in the peripheral part, the wooden surrounding edge is fixed to the corner part, the sandwiching member is attached to this surrounding edge, and one side edge of the ceiling board is sandwiched by the receiving port of this sandwiching member, so that the surrounding edge and the sandwiching member are attached. Well done easily and quickly. Further, since the sandwiching member and the joiner are directly attached to the wooden peripheral edge and the receiving member without using a hanger as in the conventional case, the space behind the ceiling is reduced and the height of the ceiling can be increased.
