Description

  The present invention relates to a floor structure suitably used as, for example, a terrace deck.

  In this specification, the term “aluminum” is used to include aluminum and its alloys.

  Conventionally, as a floor structure such as a terrace deck, a plurality of large pulls are placed and fixed in parallel on a bundle arranged at predetermined intervals in the vertical and horizontal directions, and orthogonally placed on these large pulls. A configuration is known in which a plurality of joists are placed and fixed with metal fittings, and a plurality of long floor boards are placed and fixed on the upper surface of these joists in a state orthogonal to the joists (patents). Reference 1).

As a method for fixing the long floor board to the joist, for example, a method of placing the floor board (deck material) on the joist (locked member) and screwing and fixing the screw penetrating the floor board to the joist ( Patent Document 2), a method of bridging a flat plate at an arbitrary position between steps of adjacent floor plates (deck materials), and screwing a screw penetrating the plate into the joist to fix (Patent Document 3) 4), a vertical piece of an inverted T-shaped fixing bracket provided with a horizontal piece and a vertical piece is fixed in advance to the side surface of the floor board (deck material), and the floor board is sequentially placed on the joists. A method is known in which the horizontal piece of the fixing bracket is screwed and fixed to the joist with the vertical piece of the fixing bracket fixed to the side face of the adjacent floor plate (see Patent Document 5).
Registered Utility Model No. 3046295 JP 2004-190449 A (Claim 1, FIGS. 1 to 4) JP-A-11-280144 (Claim 1, FIGS. 1 to 4) JP 2004-218111 A (Claim 1, FIG. 3) JP 2001-271417 A (Claim 1, FIGS. 1 to 4)

  However, the fixing technique described in Patent Document 2 is to fix the screw that penetrates the floor board by screwing it into the joist, and the screw work fixing work is required for each floor board, so that the workability is poor. There was a problem. Further, since the screws are driven from the upper surface of the floor board, the heads of a large number of screws appear on the surface of the floor board after the construction, and there is a problem that the appearance of the deck is poor. In addition, if it becomes necessary to replace the floorboard after construction, the floorboard can be removed by simply pulling out the screw driven into the floorboard to be replaced. When fixing with screws, it is not possible to drive the screw into the same position from the viewpoint of securing sufficient pulling strength, so the screw will be driven into a shifted position, but in this case, it will be driven into the upper surface of the floor board from the beginning of construction. Since it is in a position shifted from the position of many other screws, there is a concern that the designability is lowered.

  In addition, the fixing techniques described in Patent Documents 3 to 5 similarly have a problem that the workability is poor because the work of screwing the screws into the joists and fixing them at the time of construction is required for each floor board. In addition, there is a problem in that the appearance of the deck is not good because the screws and the fixing plates (or fixing brackets) attached and fixed to the upper surface of the floor plate from the gap between adjacent floor plates are visible and slightly noticeable. In addition, when it is necessary to replace the floor board after the construction, it is necessary to sequentially pull out the screws driven into the floor board one by one, and there is a problem that workability at the time of replacing the floor board is poor.

  The present invention has been made in view of such a technical background, and has a floor structure and a terrace deck that have a good external appearance, excellent construction workability, and excellent removal workability when replacing floorboards. The purpose is to provide.

  In order to achieve the above object, the present invention provides the following means.

[1] In a floor structure in which a plurality of long floor boards are placed and fixed in a state adjacent to each other on an upper surface of a joist,
As the floor plate, a floor plate provided with side-opening engagement recesses on both side surfaces in the width direction is used,
A leg portion of the engagement tool is attached to at least one side surface of the joist so as to be freely rotatable.
The engaging tool includes the leg portion and a pair of left and right engaging convex portions protruding from the distal end side of the leg portion toward the outer side in the width direction of the leg portion,
The leg portion of the engagement tool is sandwiched between the lower walls of the adjacent engagement recesses of the adjacent floor plates, and the left and right sides of the engagement tools are placed in a space formed by the engagement recesses of the adjacent floor plates facing each other. A pair of engaging convex portions are arranged, and one engaging convex portion of the engaging tool is engaged with a lower wall of an engaging concave portion of one floor plate of the adjacent floor plate, and the other engaging portion of the engaging tool is engaged. The floor structure is characterized in that the floor plate is fixed to the joist by engaging a mating convex portion with a lower wall of an engagement concave portion of the other floor plate of the adjacent floor plates.

  [2] The floor structure according to the preceding item 1, wherein the engagement tool is formed with a notch gap portion that is notched from the distal end side to reach the leg portion.

For example, it is not necessary to perform an auxiliary operation such as raising the engaging tool upward by hand), so that the construction work efficiency can be further improved.

  In the invention of [4], since the stopper protrusion is provided by cutting and raising, and it is easy to form the stopper protrusion, there is an advantage that the production cost can be reduced.

  In the invention of [5], since the peripheral side surface of the engaging convex portion of the engaging tool is formed in a curved surface projecting outward, when the floor plate is laid on the upper surface of the joist, the floor plate is placed on the upper surface of the joist. The operation of causing the engaging tool to rise substantially upward by moving it substantially horizontally can be performed more smoothly, and the construction workability can be further improved.

  In the invention of [6], the leg portion of the engagement tool is rotatably attached to the side face of the joist via the stepped screw, and the engagement tool can be attached to be rotatable with such a simple configuration. The cost can be reduced and the construction workability can be further improved.

  In the invention of [7], since the floor board has a hollow portion, it can be reduced in weight and cost can be reduced. And since it has a plurality of hollow parts extended along the length direction of the floor board, that is, since there is a partition plate part extended along the length direction, the strength as a floor board is also sufficient. Can be secured.

  In the invention of [8], since the joist is made of aluminum, there is an advantage that the shear strength of the joist when the attaching means such as a screw is attached can be sufficiently secured while maintaining the lightness.

  In the invention of [9], it is possible to provide a high-quality terrace deck that has a good external appearance, excellent workability, and excellent removal workability at the time of floor plate replacement.

  In the invention of [10], when the floor board is laid on the joist (with the engaging tool), the engaging tool attached to the joist so as to be rotatable is simply moved upward by simply moving the floor board substantially horizontally on the upper face of the joist. Since the floor plate can be engaged and fixed via the engaging tool while being raised, the workability of construction can be significantly improved. That is, the floor board can be fixed to the joist without requiring screwing as in the prior art. In addition, since the engaging tool is attached to the side surface of the joist, even if the engaging tool is externally seen from the gap between adjacent floor boards, the appearance is hardly noticeable.

  One embodiment of a floor structure (1) according to the present invention is shown in FIG. This floor structure (1) is a floor board support constructed on the upper surface of a floor board support structure (30) as shown in FIG. 12, that is, using a bundle (31), a large pull (32) and a joist (33).

In the engagement tool (5) shown in FIG. 15 (d), a pair of left and right engagement projections (5b) and (5b) are connected by a connection portion (5c) and engaged by these (5b), (5c) and (5b). A joint head (5e) is formed.

  Moreover, in the said embodiment, although the said engaging tool (5) employ | adopted the structure provided with the stopper protrusion (5d), it is not specifically limited to such a structure, A stopper protrusion (5d) is provided. It is also possible to adopt a configuration that does not have. However, when the stopper protrusion (5d) is not provided, the floor plate (2) is laid while performing an auxiliary operation of raising the engaging tool (5) that is rotating downward by hand, for example, by hand. On the other hand, when the stopper projection (5d) is provided, the engagement and fixing work is performed while the engagement tool (5) is raised upward by simply moving the floor plate (2) substantially horizontally on the upper surface of the joist (33). Therefore, it is preferable that the stopper projection (5d) is provided.

  Moreover, in the said embodiment, although the engaging tool (5) ... was rotatably attached with respect to one side surface of the said joist (33), it is not specifically limited to such a structure, For example, As shown in FIG. 16, it is possible to adopt a configuration in which engaging tools (5) are rotatably attached to both side surfaces of the joist (33) in the width direction, or as shown in FIG. It is also possible to adopt a configuration in which the engaging tools (5) are attached in a staggered arrangement so as to be able to rotate freely on both side surfaces in the width direction of (33).

  Moreover, in the said embodiment, although the said engagement tool (5) ... was already attached to the side surface of the said joist (33) at the stage of shipment from a factory, the structure which can be rotated freely was employ | adopted especially in such a construction method. It is not limited, For example, you may make it attach an engaging tool (5) ... to joist (33) at the time of construction work in the field.
