Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a variety of buildings, for example, a reinforced concrete structure elementary school, a junior high school or a high school building, etc. The quadrilateral) is related to the floor material connecting frame used when the wooden floor material is stretched.

[0002]

2. Description of the Related Art Conventionally, for example, when a wooden floor material is stretched on a floor in a building made of reinforced concrete or the like, it is generally performed by sticking them to a floor base with an appropriate adhesive. Was there.

[0003]

The above flooring material gradually becomes painful after a few years of use, and it is necessary to replace it.
However, as mentioned above, if it was pasted with an adhesive,
The peeling is difficult, and it is difficult to say that the tensioning work itself is originally easy. Thus, the present invention makes it possible to easily perform the floor covering operation and also the removal operation very easily as a result, so that the floor covering operation can be performed very easily. The purpose is to develop a floor material connection frame.

[0004]

The gist of the structure of the present invention is that the frame is formed in a box shape consisting of a quadrilateral bottom plate and a peripheral wall rising from each side thereof, and the bottom plate comprises: A plurality of reinforcing ridges, which also serve as a pedestal on which the floor is placed, are vertically and horizontally raised, and the peripheral wall of each side of the frame body is connected to the side of an adjacent frame body by a coupling means. Is a flooring material connecting frame.

The floor material is made of wood, and is square when viewed in plan, such as square or rectangular.
It is appropriate that these floor materials have a configuration in which the portion above the upper end of the peripheral wall is overhanged by the thickness of the peripheral wall so that the peripheral wall of the floor material connecting frame cannot be seen from the floor surface after being stretched on the base. Is. Further, as will be described later, in the case where the peripheral wall is provided with a locking brim that extends obliquely downward from the upper portion of the inner surface thereof, the lower end of the locking brim is located at a corresponding position on the circumferential side of the floor material. It is preferable to form and place a locking groove for locking. Of course, it is not inconvenient not to configure the locking groove.

It goes without saying that the frame body has a planar shape determined in accordance with the size and shape of the target floor material. As described above, since the floor material is formed in a square shape, the frame body is also formed on the basis of a corresponding square shape. In addition, it is preferable that a plurality of locking flanges inclined downward from the upper part of the inner surface of the frame are juxtaposed at appropriate intervals on the peripheral wall of the frame.
Due to the elasticity of the material of which the locking brim is made, the locking brim has an overhanging dimension that allows deformation when the flooring is loaded into the frame, to the extent that smooth loading is possible.

It is suitable that the reinforcing ridges are formed in a lattice shape when seen from a plane. Their lattice spacing is, for example,
It can be configured to alternate between long and short. On the other hand, it is preferable that the bottom plate of the frame body is interspersed with a plurality of coupling bases raised to the same height as the reinforcing ridges, and each coupling base is provided with screw holes penetrating through the front and back. .. Therefore, these joining bases are to be formed between the lattices of the reinforcing ridges, but when the intervals are configured to alternate between long and short as described above, the width is narrow. It is suitable to arrange in an appropriate number of square spaces formed between the lattices. It is suitable to provide it on the bottom plate of the frame body so as to be located at an average.

The connecting means is composed of, for example, a connecting male part and a connecting female part which is detachably connected to the connecting male part, and the connecting male part is provided on the peripheral walls of two adjacent sides of the frame. The connecting female portion may be arranged on the peripheral walls of the other two adjacent sides. Or the coupling means is
The connecting male portion and the connecting female portion detachably connected to the connecting male portion, and in the peripheral wall of each side of the frame,
The coupling male portion and the coupling female portion may be arranged at positions symmetrical to each other. Of course, other configurations can be adopted. Although various configurations can be adopted for the coupling male portion, for example, the coupling male portion may be a tongue piece that projects outward from the outer surface of the peripheral wall of the frame body, and the locking portion may hang down at the tip thereof. When the connecting male part is configured in this way, the connecting female part is formed by connecting the connecting hole into which the tongue piece can be inserted, which is formed at a corresponding position of the peripheral wall of the frame, and the locking part. It can be configured with a mating locking bar. Incidentally, it is appropriate that the frame body and all the constituent elements constituting the frame body are integrally formed of plastic having a slight elasticity.

[0009]

Since the present invention is configured as described above, when a floor material is stretched on a floor base of a building, a frame is preliminarily placed under the target floor material, and the The floor can be easily constructed by disposing the floor material on the base while coupling the coupling means of the exterior frame to each other.

The floor material can be loaded into the frame by simply pushing it in from above. When the locking brim is formed so as to extend above the inner surface of the peripheral wall, the circumferential side of the floor material is clamped by the locking brim and a certain degree of holding is secured. When the locking groove is formed on the peripheral side of the floor material so as to correspond to the above-mentioned locking flange, and the floor material is loaded in the frame as described above, the locking flange The outer end is pushed into the locking groove and is firmly held. When the floor material is loaded into the frame, the locking brim is elastically retracted in the circumferential wall direction, so that smooth loading can be ensured. When the bottom plate of the frame body is interspersed with the coupling bases having screw holes at the same height as the reinforcing ridges as described above, after loading the floor material on the frame body, move it up and down. Invert and insert a screw from the screw hole, and screw it into the floor material to secure the fixing. If the frame is not provided with the locking collar or the joining base having the screw holes, an adhesive is applied to the lower surface of the floor material, the adhesive is applied to the frame, and both are adhered.

The operation of stretching the floor material on the floor base can be performed by sequentially arranging the other floor materials on the already-arranged floor material while bringing the sides into contact with each other. When the sides are brought into contact with each other, by joining the joining means of the outer frame bodies to the bottom portions, the floor materials arranged adjacent to the already-arranged floor materials can be easily joined. .. Then, by repeating such work, it is possible to perform the work of stretching the floor material extremely easily. Further, after the completion of the tensioning, the floor members are not easily floated because the joining means of the frame bodies that are installed on the lower portion are joined together. Further, when an overhang corresponding to the thickness of the peripheral wall of the frame is formed on the upper part of the floor material on the peripheral side, the frame is completely invisible after installation on the floor base.

Further, when the flooring material is seriously damaged due to long-term use and needs to be re-covered, the flooring materials are simply connected to each other by a frame connecting means, and the flooring material is attached to the flooring base. Since it is not worn, it is easy to remove. In particular, if a part of the floor material is removed, the floor material can be removed from the floor material at that position in sequence, and can be removed only by uncoupling the coupling means. Therefore, the refilling work of the floor material can be performed extremely easily. Further, since the floor material is reinforced by the frame body, it is possible to secure a sufficient strength even with a considerably thin plate. It is also possible to use the floor material inserted in the frame body by cutting it together with the frame body at a corner of the room or a position close to the pillar.
