Description

  The present invention relates to a wood deck construction method suitable for use in a wood deck installed on a veranda or a terrace provided in a house or facility.

  In general, wood decks installed on verandas or terraces provided in houses and facilities so that they can go directly to the outdoors without using external footwear are popular. It is installed by a construction method in which a plurality of deck materials are arranged and fixed on a plurality of joists arranged at predetermined intervals on the construction surface.

Conventionally, as a construction method of such a wood deck, a construction method disclosed in Japanese Patent Application Laid-Open No. 2003-27719 is known. FIG. 10 shows a wood deck Dr installed by a general construction method similar to the construction method disclosed in the publication. This construction method is an attachment in which a slit 54a in a longitudinal direction provided on a side surface of an arbitrary deck material 54 arranged so as to intersect the joist material 51 on an upper surface 51u of the joist material 51 has a work-shaped end surface. One side of the member 52 is fitted, and the attachment member 52 and the joist member 51, the attachment member 52 and the deck member 54 are fixed by tapping screws 53, respectively, and a longitudinal slit 54b provided on the side surface of the other deck member 54 is provided.

  However, the conventional wood deck construction method described above has the following problems.

  First, since at least one side in the width direction of the deck material 54 is fixed only by fitting to the mounting member 52 and not fixed to the joist material 51, the overall strength and rigidity after construction is set. This is disadvantageous in that it is difficult to endure, such as being susceptible to rattling due to impact or long-term use.

  Secondly, since it is necessary to construct the deck materials 54 one by one, the construction takes time and labor, and becomes inefficient. Moreover, when one deck member 54 is displaced due to an inclination or the like, the position displacement directly affects the other deck members 54 to be constructed thereafter, and it is difficult to obtain a high-quality wood deck.

  Third, due to the construction structure, the deck materials 54 cannot be partially exchanged. Therefore, when the deck material 54 is partially exchanged due to breakage or dirt, the deck material 54 has to be removed from the end of the row to which the deck material 54 belongs, and the exchange work becomes difficult. At the same time, there is a risk of damaging other parts and materials, which makes it difficult to maintain.
