Description

  The present invention relates to a deck material fixing tool, that is, a fixing tool for fixing a deck material in a garden deck to a joist.

  Generally, a garden deck (hereinafter simply referred to as “deck”) installed outdoors has a plurality of large pulls fixed to the upper ends of a plurality of bundles standing on a slab, and a joist is placed between the large pulls. The deck material is constructed in such a manner that the deck material is placed in parallel, and deck materials extending in a direction perpendicular to the longitudinal direction of the joists are sequentially placed on the joists, and the respective deck materials are sequentially fixed using some fixing tool. In order to improve the drainage performance of rain that has fallen on the upper surface and the disposal performance of dust, the deck material is fixed so that a certain gap is secured between the deck materials.

In the past decks, the screws passed through the deck material placed on the joists, and the screws were screwed into the joists, so the heads of the screws protruded to the top of the deck as the deck was used, causing injury. In recent years, it has been difficult to form a uniform gap between the deck materials. There has been proposed a dette material fixing technique in which a uniform gap is secured by restricting the position of each deck material by a fixing tool (see Patent Documents 1 to 3).

Then, by bringing the deck materials 102a and 102b close together, a screw 105 is passed through the stop plate 104 in a state where a predetermined gap is formed between the deck materials, and screwed into the joist 101 to fix one end of both deck materials 102a and 102b. Fix it. As for the deck material 102b on the right side and the deck material placed on the right side of the deck material, the same stopper plate is placed over the stepped portions of the adjacent deck materials in the same manner as the previous time, and both deck materials are brought close to each other with a predetermined gap. The deck in which a uniform gap is formed between the deck members is formed by forming and passing the screw through the stopper plate and screwing it into the joist.

  In addition, as shown in FIG. 7, in Patent Document 2, an insertion portion bent outwardly at both upper end portions in a concave groove 203a formed at the end portion of the first deck material 202a placed on the joist 201. The fixing tool 204 is fixed by fitting one insertion portion 204a of the U-shaped fixing device 204 having 204a and 204b and screwing the screw 205 penetrating through the bottom of the fixing device into the joist 201, and the right deck. By placing the material 202b on the joist 201 and approaching the direction of the previous deck material 202a and fitting the other insertion portion 204b of the fixture into the concave groove 203b, a gap of a predetermined dimension is secured between the adjacent deck materials. It is what you do.
