Description

  The present invention relates to a deck material fixing structure when a floor material called a deck material is constructed on a terrace, a balcony, or the like.

The deck material is used as a flooring material for a terrace provided in a garden or the like of a building or a flooring material for a balcony or a veranda that protrudes outward from a room of the building.
In this case, a plurality of deck materials are laid substantially in parallel with a predetermined gap.
This is provided with a gap in consideration of drainage, etc., but conventionally, for example, as shown in Patent Documents 1 and 2, the deck material is only pressed down on both sides with metal fittings and fixtures. There is a problem that the joist and the base material are seen through the gap of the gap and the appearance is poor, and the deck material is displaced in the longitudinal direction when the metal fittings and the fixture are loosened for some reason.
Further, in the conventional fixing method of the deck material, the size of the metal fitting and the size of the head of the screw member such as a screw are limited, and it is difficult to reduce the gap, and the fall of small items such as coins becomes a problem. In addition, children's fingers could be pinched at nursery schools and kindergartens, and pedestrians could crawl at nursing homes.
Furthermore, for some reason, only a part of the deck material needs to be removed and replaceable after the construction of the deck material.

Japanese Patent No. 5377196 Japanese Patent No. 5302662

  An object of the present invention is to provide a fixing structure of a deck material that can reduce a gap between the deck materials and prevent the deck material from being displaced.

  The deck material fixing structure according to the present invention is a deck material fixing structure in which a plurality of deck materials are arranged substantially parallel to a joist or a base material, and fixed using a fixing tool. The opposing side surfaces have concave portions each consisting of an opposing opening, and one deck material has a projecting piece formed to project from the lower surface side to the other deck material side, The deck material has a cutout portion for swallowing the protruding piece portion, and the fixing member is a pair of stoppers that are in contact with the upper surface of the protruding piece portion and the recessed portions provided in the deck materials on both sides. The pair of locking portions provided on the fixture are positioned in the recesses of the deck material in a state where the protruding piece portion of one deck material is inserted into the notch portion of the other deck material. The screw member is passed through the projecting piece of the deck material from above the holding part of the fixing tool, and the root Or it is screwed to the base material, and the screw member has a head larger than the screw diameter and the gap width on the upper surface side of the deck material on both sides is smaller than the outer diameter of the head, And the total length of a screw member is shorter than the height dimension of the inner side upper end surface of the recessed part provided in the deck material of the said both sides, It is characterized by the above-mentioned.

Here, the deck material is a flat building material whose length is relatively longer than the width, and is made of various materials such as wood, resin material, composite material of wood powder and resin, weight reduction, etc. For this purpose, hollow cross-sections and the like are also used.
These deck materials are often installed with joists or base materials, but the present invention is used when a plurality of deck materials are constructed so as to form a predetermined gap as a terrace, balcony, veranda or the like. Everything is included.

In this invention, you may make it a fixing tool have a positioning part for positioning the space | interval of the deck material of both sides.
If it does in this way, the arrangement | positioning between a deck material will become fixed only by arrange | positioning a fixing tool to one deck material and arranging the other deck material so that it may press on the positioning part of a fixing tool.

In this invention, you may make it a fixing tool have the accommodating part of the said head so that the height of the head of the said screw member may become low at the time of screwing.
If it does in this way, the full length of a screw member can be shortened by the part | minute of the depth of an accommodating part.

In the deck material fixing structure according to the present invention, not only the deck materials on both sides arranged substantially in parallel are locked so as to be pressed by a pair of locking portions provided on the fixing tool, but also the pressing portion of the fixing tool. Since the screw tip of the screw member is inserted from the top and the projecting piece of the deck material is penetrated and screwed to the joist or the base material, the screw member penetrates the projecting piece even if the screw member is loosened somewhat. Because it is, there is no deviation.
Also, when looking at both sides of the deck material, one side is screwed at the protruding piece, while the other side is only locked at the locking part, so changes in temperature, etc. Can absorb the expansion and contraction variables such as deck material and joists.
In the present invention, since the projecting piece of one deck material is fixed in a state of being squeezed into the notch of the other deck material, the joist and the base material are not visible from the gap of the deck material, and it looks good. Even if a small item such as a coin enters the gap, it will be placed on the protruding piece of the deck material and will not fall from the gap such as joists.
In the present invention, since the overall length of the screw member is shorter than the height dimension of the inner upper end surface of the recess opened toward the opposing surfaces of the deck materials on both sides, the screw member is larger than the gap width on the upper surface side of the deck materials on both sides. Even if the head outer diameter is large, the deck material can be partially removed or replaced by using a tool that can be inserted through this gap.
