- the present invention relates to a floor plate fixture suitable for fixing a synthetic wood floor plate by a method according to Japanese Patent No. 3543221 or the like.
- this wood deck is as follows. As shown in FIG. 7, as shown in FIG. 7, a bundle column 6 is erected on an installation surface 9 where a foundation is placed on the ground surface as necessary. A support material 5 such as joists is installed on the pillar 6, and a deck panel, which is a floor plate 4, is placed on the support material 5 side by side in parallel in a certain direction at a predetermined interval. It is performed by fixing to the support material 5.

- the side surface of the floor plate 4 can be removed even if the floor plate 4 is pulled upward from the support material 5. Since the inner wall of the slit 41 formed in 40 is in contact with the flange portion 101 or the bridging piece 111 of the floor plate fixtures 100 and 110, the floor plate 4 is fixed on the support material 5 and cannot be peeled off. .

- the contact resistance to 40 is further increased.
- the contact state between the floor board 4 and the floor board fixture 1 is such that the floor board 4 does not move with respect to a load or force applied in a normal use state, such as when a person walks on the floor board 4. Generate enough force to fix.
- the floor board 4 when the floor board 4 expands and contracts with changes in temperature and humidity, the dimension of the floor board 4 itself changes, and an extremely strong force is generated to move the contact position with the floor board fixture 1.
- the floor plate 4 and the floor plate fixture 1 are not directly fixed by a nail, a screw nail, an adhesive or the like as described above, the floor plate 4 can be allowed to move. ing.
- the floor board fixing tool 1 is damaged, the screw nail 7 that fixes the floor board fixing tool 1 to the support member 5 is removed, and further, the floor board 4 can be suitably prevented from being deformed such as warpage or distortion.
- this floor board fixture 1 As shown in FIG. 2, in the floor board fixture 1 provided with the ridges 22 in which the sharp top portions 22a are arranged so as to be biased toward either one of the width directions of the ridges 22, this floor board fixture 1 As shown in FIGS. 6 (A) and 6 (B), the force that the floor plate fixture 1 tries to regulate the movement of the floor plate 4 is as follows. 6B, the force that regulates the floor plate 4 that is going to move in the direction of arrow A shown in FIG. 6A is compared with the case where the floor plate 4 that is going to move in the direction of arrow B is restricted in FIG. Becomes stronger.
- the ridge 22 of the floor plate fixture 1 formed of a flexible material is the top portion 22a. Is pulled by the movement of the floor plate 4 and deforms so as to spread outward as indicated by an arrow a in the figure. As a result, the contact resistance with the side surface 40 of the floor board 4 increases due to the deformation of the ridges 22.
- the protrusion 22 of the floor plate fixture 1 made of a flexible material has a top portion 22a that moves the floor plate 4. As shown by the arrow b in the figure, it is deformed so as to narrow inward. As a result, when the protruding strip 22 having the above-described shape is provided, the floor plate fixture 1 more firmly regulates the movement of the floor plate 4 attempting to move in the arrow A direction relative to the floor plate 4 attempting to move in the arrow B direction. .
- the restriction force for the movement of the floor board 4 varies depending on the orientation.
- the floorboard fixtures 1 (1a to 1d) are alternately arranged in the opposite directions and the floorboard 4 is about to move in the direction of arrow A in FIG.
- the floor plate fixing tool 1b, 1d exerts the action of firmly restricting the movement so that the floor plate 4 is in the longitudinal direction. It may not be moved in any direction.
- the regulation force for the movement of the floor board 4 in the direction away from the rung may be attached so as to be large. In such a configuration, one end of the floor plate 4 is always maintained in a state where it abuts against the rung.
- the floor plate fixing tool 1a when the floor plate 4 with one end spaced apart from the cross is expanded and deformed so as to increase in size, the floor plate fixing tool 1a is more deformed than the floor plate fixing tool 1b.
- its ability to regulate movement is weak. Therefore, the floor board 4 expand
- the floor board 4 when the floor board 4 is contracted to reduce the size, the floor board is contracted at the right end in the figure because the regulation force of the floor board fixture 1b is weaker than that of the floor board fixture 1a. As a result of the deformation, the floor plate 4 can be automatically returned to the original position (position at the time of construction) where the floor plate 4 abuts the rung as the floor plate 4 expands and contracts.
