Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a frame structure for constructing the ceiling of a vinyl house.

[Conventional technology]

When assembling a frame for the ceiling of a vinyl house, it must be strong enough to support the shelf lines that support the vinyl, and that the tips of the aggregate will not pierce the vinyl that will be placed on top of it or the workers. It is necessary to have a structure like this.

For this reason, one of the structures conventionally employed is, for example, the structure shown in FIG. 6a. As shown in Figures 6b and 6c, this structure consists of shelf lines d stretched in the length direction on the ceiling of the vinyl house.
Then, a hook part b formed by bending the end of the elastic wire a into a hook shape is locked, and the shelf wire d and the elastic wire a are wound using a fastening fitting c wound in a coil. It is something to be installed.

[Problem that the invention attempts to solve]

However, in the installation using this method, the end of the elastic wire a used as the aggregate gets caught up in the fastener c, and although it is safe because it does not protrude, the tightening state by the fastener c is incomplete. can be,
There were drawbacks in that the arch part swung around the hook part b that was locked to the shelf line d, and the hook part b slid on the shelf line d, making it impossible to secure the ceiling sufficiently.

The purpose of the present invention is to eliminate these drawbacks and construct a strong frame for ceilings of vinyl houses with a simple structure.

[Means for solving problems]

The framework structure for the ceiling of a vinyl house of the present invention is made of elastic wires whose tips are bent to form hooks in the same plane as the surface where the recesses are formed and which hold the intersecting shelf lines near the ends. aggregate, a shelf line locked in a recessed part of the aggregate, a recessed part for locking and supporting the shelf line, and an aggregate at a position opposite to the hook part at the tip of the aggregate. The above drawbacks of the conventional attachment mechanism can be overcome by constructing a fastening fitting made of an elastic wire and having a recessed portion for locking and supporting the aggregate end hook portion and a recessed portion for locking and supporting the aggregate tip hook portion. It has been resolved.

〔Example〕

1 to 5 show an embodiment of the present invention, FIGS. 1 and 2 show the shape of the aggregate 1, and FIG. 3 shows the shape of the tip of the aggregate 1. FIG. 4 shows the frame structure of the present invention, and FIG. 5 shows the fastening fitting 5.

The aggregate 1 shown in Figures 1 and 2 is made of elastic wire to form the curved surface of the ceiling, and as shown in Figure 3, which shows the shape near each end, it is used to secure the shelf wire. A recessed portion 2 and a hook portion 3 for locking with a fastening fitting 5 are provided. Same aggregate 1
The recessed part 2 and the hook part 3 are arranged so that they each face the same direction or opposite directions, and are arranged in the same direction, as shown in FIGS. It is formed so that it lies within the plane.

The frame structure of the present invention has the form shown in FIG. 4, with the aggregate 1 shown in FIGS. 1 to 3 as the core.

In a depression 2 formed at the tip of the aggregate 1 that forms the curved surface of the ceiling, a shelf line 4 stretched in the longitudinal direction of the ceiling is placed to place the ceiling vinyl.
is cross-locked.

Furthermore, in order to fix the shelf wire 4 which intersects with the aggregate 1 and is locked in the recessed portion 2 thereof, a fastening fitting 5 made of an elastic wire is used. The fastening fitting 5 may be ring-shaped as shown in the figure, or may be pin-shaped with a closed ring. In short, as shown in FIG. 5, a central recess 6 is provided at the center of the elastic wire to engage with the tip hook 3 of the aggregate 1.
, intermediate recessed parts 7, 7 for supporting the shelf line 4 at a position away from the point where it intersects with the aggregate 1, and a position opposite to the tip hook part 3 when viewed from the point where the shelf line 4 intersects with the aggregate 1. Side end recess 8 for locking aggregate 1
It is sufficient as long as it has the following.

By means of the fastening fittings 5, the aggregate 1 and the shelf line 4 are engaged and fixed in the respective recesses 6, 7, and 8.

As a result, even if an external force such as wind acts on the erected ceiling frame of a vinyl house, the fastening metal fittings 5 can support the aggregate 1 and the shelf line 4 at least in the vertical and horizontal directions centering on the recessed part 2. Because they are attached to each other, they do not slide or shift from each other.

[Effect of idea]

According to the vinyl house ceiling frame of the present invention, (a) there is little bending of the elastic wire material, and the structure is simple together with the fastening metal fittings used for assembly; (b) The ceiling frame can be firmly and easily assembled using the fastening metal fittings. Vinyl houses constructed with strong ceiling frames are less likely to be shaken by wind, etc., and can withstand long-term use.
