Description

  The present invention relates to a flooring connecting bracket that can connect a flooring and a flooring when laying the flooring on a joist. In particular, the present invention relates to a flooring connecting bracket that can reduce the interval between flooring materials and the width of the flooring connecting bracket. Moreover, this invention relates to the flooring coupling metal fitting which can adjust the height of the said flooring easily according to the kind of flooring. In addition, the said floor material coupling metal fitting is produced, for example by shaping | molding by an aluminum alloy, a synthetic resin material, etc., or processing from a metal plate material. Further, the joists are laid directly on the soil, concrete slab, wooden base material, steel floor base material, concrete slab or the like via cushions, springs, level adjusting bolts and the like.

  In recent years, more and more flooring materials have taken into consideration people and the environment, such as outdoor walking decks using natural trees that are kind to people, outdoor decks laid around trees, verandas, and rooftops. Further, the floor material is not limited to wood, and an aluminum alloy shape material, a shape shape of a synthetic resin material, or a shape obtained by molding a powder of a synthetic resin material and wood is used. Further, in the conventional example shown in FIG. 11 (b), for example, two flooring materials 32 'are connected by a flooring material fitting 11'.

  The floor material connecting bracket 11 'is composed of a lower bracket and an upper bracket. The lower metal fitting is composed of a lower substrate 121 'and a vertical portion 122' that is integrally connected vertically on the lower substrate 121 'and has a convex portion 123' integrally formed on the upper portion. The upper metal fitting includes an upper substrate 131 ′, a fitting recess 132 ′ that hangs right below the upper substrate 131 ′, and a retaining protrusion 133 ′ that narrows the width of the lower portion of the fitting recess 132 ′. It is configured. The protrusions 123 'integrally connected to the vertical portion 122' are fitted to each other while sliding into the fitting recess 132 '.

  The floor material 32 'is narrow so that the upper space 323' between the floor materials 32 'is not more than a specified value, and the lower space so that the fitting recess 132' of the floor material coupling metal fitting 11 'can be slid and inserted. Two-stage grooves are provided so as to widen (W ′) 322 ′. However, the floor connecting bracket 11 ′ shown in FIG. 11 (b) has an upper width of 5 mm to 6 mm so that high heels do not enter between the floor materials. Has the disadvantage of requiring two-stage machining.

  Further, for example, in a wooden floor covering laying apparatus disclosed in Japanese Patent Application Laid-Open No. 2002-106155, a joist having a height adjusted with a bolt is laid on a concrete slab. On the joist, a substantially H-shaped connecting fitting is slidably attached. Further, the connecting metal fittings are attached to each other by being fitted into slide grooves provided on the side portions of the flooring material.

JP 2002-106155 A

  In the conventional example shown in FIG. 11 (b), the floor material connecting bracket 11 'has a thickness (a) of the fitting recess 132, a thickness (b) of the retaining protrusion 133', and a vertical portion 122 '. There is a thickness (a), and the interval W ′ between the flooring materials must be at least 3a + 2b. In addition, when the space between the flooring materials is wider than the specified width, the bottom of the high heels or the tip of the umbrella enters, not only poses a danger to the pedestrian, but also the width of the connecting bracket that connects the flooring material, Or the side groove of the floor material which pinches | interposes the said connection metal fitting also becomes deep, and there existed a problem that the cost would become expensive in the case of performing a two-step side process.

  The conventional flooring connecting metal fittings only connect the side portions of the flooring, and it is difficult to narrow the interval between the flooring materials. Since the floor material connecting bracket of the conventional example has a wide portion in the lower part, it is necessary to cut off the floor material so as to fit in the floor material, and there is a problem that the cost is increased as man-hours.
