Description

  The present invention relates to a deck, and more particularly, to a deck having a base structure in which large draws and joists are assembled like a cross.

2. Description of the Related Art Conventionally, as a deck installed outdoors, a structure is known in which a large pull is bridged between the upper portions of a plurality of bundle pillars to form a gate-shaped base, and a deck material is laid between the upper portions of the large pull.
On the other hand, there is also a deck that has a structure in which a large pull is bridged between the upper parts of the bundle pillars, a joist is formed with a gap between the large pulls and a joist is laid, and a deck material is laid between the upper parts of the joists. Known (see, for example, Patent Documents 1 and 2).

  In the case of a deck with a cross-shaped base structure, the load applied to the deck material is once received by the joists and transmitted from the joists to the fork. There is no need to support with a bunch of pillars. Therefore, in the case of the base structure on the cross beam, there is a merit that the number of bundle pillars and the number of bundle foundations can be reduced because there is only a small number of bundle pillars that support the large pull.

JP 2005-344371 A JP-A-8-4253

  However, even if it has a cross-shaped base structure, in the deck described in Patent Document 1, the pulling and joist are firmly connected to each other via the connecting metal fitting, resulting in the construction accuracy of the bundle pillars. If the ends of the large pulls are not aligned or the parallelism is not secured, the joists cannot be properly attached to the large pulls using the connecting fittings. Therefore, it is necessary to carefully perform the construction of the bundle pillars to improve the construction accuracy, and there is a problem that the construction takes time.

Further, in the deck described in Patent Document 2, the joist is directly screwed to the large pull. For this reason, even if a position shift occurs due to the construction accuracy of the bundle pillar, the joist can be appropriately bridged regardless of the position shift.
However, in the structure in which the joist is directly screwed to the large joist, since the misalignment tends to occur toward the joists at the time of joining each other, the construction cannot be performed stably and the ends of the joists are not aligned. Or the parallelism cannot be secured. Therefore, it is still necessary to perform the construction carefully, and there is a problem that the construction takes time.

  An object of the present invention is to provide a deck that can be easily constructed and can have a good finish.

The deck according to the present invention includes a plurality of bundle pillars, a plurality of large pulls spanned between the bundle pillars, a plurality of joists spanned between the large pulls, and a plurality of decks spanned between the joists a deck and a timber having the attachment interposed between the large pull and the joists, the attachment is a pair of guide and the upper surface portion, a movement in the longitudinal direction of the joists guide And is fixed to the large pull by a screw passing through the upper surface portion, the joist has a fixed piece fixed to the large pull, and the fixed piece extends along the longitudinal direction of the joist are vertically continuously have a pair of vertical pieces guided by the guide portion of the attachment Te, between the vertical piece of the joists said attachment is arranged, and the said guide portion of the attachment Between the vertical piece of thick, characterized in that the gap is provided.

According to the present invention, a gap is provided between the vertical piece of joist and the guide portion of the attachment fixed to the large pull, and the joist is not fixed to the attachment but is fixed to the large pull. Therefore, even if there is a subtle variation in the orientation of the attachment on the large pull, the effect of such a variation on the parallelism between joists is small.
For this reason, the attachment is fixed at a predetermined position even when the end position of the large pulling is slightly displaced due to the position accuracy of the bundle pillar or the parallelism of the large pulling is not ensured. By doing so, the gap between the attachment and the joists can be absorbed by the gap between the attachments and the joists, and the parallelism between the joists can be reliably ensured. Accordingly, the deck material is laid at an appropriate position with respect to the joists, and the finish as a deck can be improved.
At this time, positioning in the longitudinal direction of the joist is necessary, but for joist positioning, it is only necessary to move the joist with respect to the attachment fixed to the joist. There is no worry of displacement in the longitudinal direction, and construction can be facilitated.
Further, according to the present invention, since the joists only have to be directly fixed to the fork by using a fixing piece, a conventional connecting metal fitting having a complicated shape can be made unnecessary, and the fixing operation can be simplified. Furthermore, with the fixed piece including the vertical piece, both the movement of the joist while being guided by the attachment and the fixation of the joist to the pulling can be performed, and there is no need to provide movement and fixation by providing separate parts. The shape can be simplified and material costs can be reduced. In addition, by providing the fixed piece continuously in the longitudinal direction of the joist, the fixed piece is always located on the large pull, and even if the joist is positioned at any position, the joist is placed through the fixed piece. It can be securely fixed to the large pull.

In the deck according to the present invention, the attachment includes a rectangular upper surface portion and a locking piece that hangs downward along a pair of opposite edges of the upper surface portion, and It is desirable to have an upper surface on which the upper surface portion of the attachment is placed and a pair of engaging portions that are provided along the longitudinal direction and are engaged with the locking pieces.
According to the present invention, since the attachment is locked to the large pull by the locking piece, even in the operation of fixing the attachment to the large pull, it can be performed with the attachment locked, and the attachment is large during the fixing operation. There is no risk of falling out of the pull or being displaced and fixed, and the work can be performed accurately and quickly.

In the deck of the present invention, it is preferable that the joist fixing piece has an L-shaped cross section having a vertical piece and a horizontal piece, and the joist is fixed to the large pull by a screw penetrating the horizontal piece.
According to the present invention, since it is only necessary to screw a screw into the horizontal piece from above, the joist can be fixed to the large pulling in an easy posture, and the burden on the operator can be reduced.

The perspective view which shows the principal part of the deck which concerns on one Embodiment of this invention. It is a perspective view of the said deck, and is explanatory drawing for demonstrating the construction procedure of a deck in order of (A)-(D). Explanatory drawing for demonstrating the further detailed construction procedure of the said deck in order of (A)-(C).

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
1 and 2A, a deck 10 of the present embodiment includes a plurality of independent bundle foundations (not shown), a plurality of bundle pillars 11 standing on the bundle foundation, and bundle pillars spaced from each other. A plurality of large forks 12 spanned between 11, a plurality of joists 13 spanned between the large forks 12 so as to be spaced apart along the longitudinal direction of the large forks 12, and laid between the joists 13 A plurality of deck members 14. As described above, the deck 10 is configured to have a cross-shaped base structure by including the large pull 12 and the joists 13. In the present embodiment, an attachment 15 is interposed between the fork 12 and the joists 13.

  Here, the bundle foundation is a foundation portion on which a bundle pillar is erected, and includes an independent foundation stone made of concrete or natural cobblestone, and a solid foundation made of concrete soil.

  The bundle pillar 11, the large pull 12, the joist 13, and the attachment 15 of this embodiment are made of an aluminum extruded profile. The deck material 14 is a molded member made of a synthetic resin containing wood powder. The number, the number, the length, etc. of these members are appropriately changed according to the specifications such as the size of the deck 10.

A bundle foundation is provided for each bundle pillar 11. Further, when the bundle foundation is constructed in a cold region, it is buried or placed deeply up to the freezing depth.
The bundle pillar 11 is screwed to the upper surface of the bundle foundation via an L-shaped bracket (not shown). In the present embodiment, two bundle pillars 11 are used for one large pull 12, and these bundle pillars 11 support both ends of the large pull 12.

  The large pull 12 has a substantially convex cross section. A vertical fixing piece 12 </ b> B that is continuous along the longitudinal direction is suspended downward from the lower end edges of the pair of side surfaces 12 </ b> A that are separated from the large pull 12. The upper side of the bundle pillar 11 is accommodated between these fixed pieces 12B, and the large pull 12 is fixed to the upper side of the bundle pillar 11 by a screw 16 penetrating the fixed piece 12B horizontally. Engaging portions 12 </ b> D extending horizontally outward are continuously provided on both side edges of the upper surface 12 </ b> C of the large pull 12 along the longitudinal direction of the large pull 12. In addition, in the large pull 12 having a convex cross-sectional shape, both sides of the upper surface 12C do not reach the side surface 12A, and the position of the engaging portion 12D is positioned on the inner side of the side surface 12A.

  The joist 13 also has a substantially convex cross section. A fixed piece 13 </ b> B continuous along the longitudinal direction is suspended downward from the lower end edge of the pair of spaced side surfaces 13 </ b> A of the joist 13. The fixed piece 13B has an L-shaped cross section having a vertical piece 13C and a horizontal piece 13D. The horizontal piece 13D of the fixed piece 13B extends outward and is installed on the upper surface 12C of the large pull 12. The joist 13 is fixed to the upper surface 12 </ b> C of the large pull 12 by a screw 17 penetrating the horizontal piece 13 </ b> D from above. Further, the joist 13 is also provided with an engaging portion 13E similar to the large pull 12. An attachment member (not shown) is engaged with such an engaging portion 13E.

  In FIG. 2, the deck members 14 are depicted as being integrated with each other, but actually, the deck members 14 are laid on the joists 13 via the mounting members one by one. The mounting member is screwed to the joist 13 while being engaged with the engaging portion 13E of the joist 13. However, since the fixing structure of the deck member 14 to the joist 13 using such an attachment member is known, detailed illustration and description here are omitted.

  The attachment 15 has a rectangular upper surface portion 15A, and a locking piece 15B suspended downward along a pair of opposite edges of the upper surface portion 15A. is there. The attachment 15 is placed so that the locking piece 15B extends along the engaging portion 12D of the large pull 12 and the upper surface portion 15A overlaps the upper surface 12C. In the mounted state, the entire width of the upper surface 12 </ b> C of the large pull 12 is disposed between the locking pieces 15 </ b> B of the large pull 12. The locking piece 15B is locked to the engaging portion 12D of the large pull 12 so that the attachment 15 does not easily fall off from the large pull 12. The attachment 15 positioned at a predetermined position of the large pull 12 is fixed to the upper surface 12C of the large pull 12 with a screw 18 from above.

  The dimension of the attachment 15 along the longitudinal direction of the pulling 12 is substantially the same as the dimension between the vertical pieces 13 </ b> C forming the fixed piece 13 </ b> B of the joist 13. Such an attachment 15 is disposed between the vertical pieces 13 </ b> C of the joists 13. In the state where the attachment 15 is disposed on the joist 13, the joist 13 can be moved along the longitudinal direction with respect to the attachment 15.

  At this time, in the attachment 15, a pair of horizontal edges perpendicular to the locking piece 15 </ b> B form the guide portion 15 </ b> C. Accordingly, the vertical piece 13C of the joist 13 and the guide portion 15C are close to each other, and when the joist 13 is moved, the vertical piece 13C is guided by the guide portion 15C. From this, the joist 13 moves along its longitudinal direction, that is, the bridging direction, and the position of the joist 13 in the longitudinal direction can be easily adjusted without being displaced in the longitudinal direction of the large pull 12. is there.

  Moreover, the dimension along the longitudinal direction of the pulling 12 in the attachment 15 and the dimension between the vertical pieces 13C of the joists 13 are substantially the same, indicating that the joists 13 move with respect to the attachment 15 without difficulty. It is almost the same after taking into account. Therefore, a slight gap of the joist 13 exists between the guide portion 15 </ b> C of the attachment 15 and the vertical piece 13 </ b> C of the joist 13. Due to this gap, construction errors between the bundle pillar 11 and the large pull 12 are absorbed.

Below, the construction procedure of the deck 10 will be schematically described based on FIGS. 2 (A) to 2 (D) and FIGS. 3 (A) to 3 (C).
As shown in FIG. 2A, first, the bundle pillar 11 is erected and fixed at the marked position on the bundle foundation (not shown), and the large pull 12 is bridged between the bundle pillars 11 and fixed. . At this time, the construction accuracy of the bundle pillar 11 is limited, and as shown in FIG. 3 (A), the dimension A1 between the end portions on the one end side of the large pull 12 installed between the bundle pillars 11 and the other end The difference with the dimension A2 may increase.

  For example, when the length dimension of the large pull 12 is 5000 (mm), the maximum construction error that occurs between the dimension A1 and the dimension A2 is 10 (mm). The gap is set to about 1 (mm) so that such a construction error can be absorbed by the gap between the vertical piece 13C of the joist 13 and the guide portion 15C of the attachment 15. In the following, due to the difference between the dimensions A1 and A2, the distance between the wall surface 1 of the building and the large fork 12 adjacent to the wall becomes smaller on the left side in the figure, and the wall 1 on the right side in the figure becomes smaller. The construction procedure will be described assuming a case where the distance between the head and the large pull 12 becomes large.

  As shown in FIGS. 3A and 2B, the first one of the joists 13 is bridged between the ends of the large pull 12 on one end side of the large pull 12. About this first joist 13, the exact angle (for example, right angle) with respect to the wall surface 1 is taken out. When the angle comes out, the dimension B1 between the end portion of the joist 13 and the wall surface 1 is taken out, and the joist 13 is fixed to the large pull 12 with the screw 17 without using the attachment 15. Further, in order to attach the other two joists 13, the attachments 15 are positioned at intervals of a predetermined dimension C1 and fixed to the large pull 12 with screws 18.

  Next, as shown in FIG. 3 (B), the other two joists 13 are dimensioned diagonally with reference to the corners 13F and 13G at both ends of the first joists 13. Specifically, the diagonal dimension of the corner portion 13F on the wall surface 1 side of the first joist 13 and the corner portion 13G on the side separated from the wall surface 1 of the center joist 13 is D1, and the wall surface 1 of the first joist 13 is set to D1. When the diagonal dimension of the corner portion 13G on the side away from the corner portion 13F and the corner portion 13F on the wall surface 1 side of the central joist 13 is d1, the central joist 13 is moved in the longitudinal direction so that D1 = d1. Adjust the position. After this position adjustment, the central joist 13 is fixed to the large pull 12.

  Similarly, the diagonal dimension of the corner 13F of the first joist 13 and the corner 13G of the left joist 13 is D2, and the diagonal of the corner 13G of the first joist 13 and the corner 13F of the left joist 13 is the same. When the dimension is d2, the left joist 13 is moved in the longitudinal direction to adjust the position so that D2 = d2. After this position adjustment, the left joist 13 is fixed to the large pull 12.

By doing so, each joist 13 has an appropriate positional relationship with respect to the wall surface 1 without being affected by the construction accuracy of the bundle pillars 11 and the large pull 12 as shown in FIG. It will be handed over to the big draw 12. In this state, the joist 13 is fixed to the large pull 12 with the screw 17. Thereafter, as shown in FIG. 2 (C), the deck material 14 is installed on the joists 13 using, for example, mounting members in order from the side closer to the wall surface 1.
Thus, the deck 10 shown in FIG. 2D is obtained.

According to the present embodiment described above, there are the following effects.
(1) That is, there is a gap between the vertical piece 13C of the joist 13 laid on the deck 10 and the guide portion 15C of the attachment 15, so that the joist 13 can be moved. Even when the end position of the large pull 12 is slightly displaced due to position accuracy or the parallelism of the large pull is not ensured, and a construction error occurs, the attachment 15 is determined at a predetermined position. If it fixes to, the shift | offset | difference of the large pull 12 by such a construction error can be absorbed in the clearance gap between the joist 13 and the attachment 15, and the parallelism etc. between the joists 13 can be ensured reliably. Accordingly, the deck material 14 is laid at an appropriate position with respect to the joists 13, and the finish as the deck 10 can be improved.

(2) Although there is a necessary tolerance for assembly between the large pull 12 and the attachment 15, the joist 13 is not fixed to the attachment 15 but directly fixed to the large pull 12. Yes. For this reason, even if the orientation of the attachment 15 on the pullout 12 varies somewhat due to such tolerances, the variation hardly affects the pitch or parallelism between the joists 13, and the joists 13 are attached to the wall surface 1. On the other hand, it can be bridged in the direction orthogonal to the other.

(3) When the joist 13 is bridged between the large pulls 12, it is necessary to position the joist 13 in the longitudinal direction, but the joist 13 is positioned with respect to the attachment 15 fixed to the large pull 12. Therefore, there is no concern that the joist 13 is displaced in the longitudinal direction of the large pull 12 during the positioning work of the joist 13, and stable construction can be realized.

(4) Since the attachment 15 is locked to the large pull 12 by the locking piece 15B, the operation of fixing the attachment 15 to the large pull 12 can be performed with the attachment 15 locked. During the fixing work, the work can be quickly performed without falling off the large pull 12 or being fixed with a large displacement.

(5) Since the joist 13 is directly fixed to the large pull 12 by using the fixed piece 13B of the joist 13, by providing the fixed piece 13B, the movement of the joist 13 relative to the attachment 15 and the Both the joist 13 and the joist 13 can be fixed, and there is no need to provide separate parts for moving and fixing, and the shape of the joist 13 can be simplified and the material cost and the like can be reduced. Further, by providing the fixing piece 13B, a conventional connecting metal fitting having a complicated shape can be made unnecessary, and the fixing operation can be simplified.
Further, since the fixed piece 13B is continuous in the longitudinal direction of the joist 13, the fixed piece 13B is always positioned on the pulling 12, and the joist 13 is positioned at any position in the longitudinal direction. Even in this case, the joist 13 can be securely fixed to the large pull 12.

(6) When fixing the joist 13, it is only necessary to screw a screw into the horizontal piece 13D forming the fixing piece 13B from above, and the joist 13 can be easily fixed to the large pull 12 in an easy posture. , Can reduce the burden on the operator.

(7) Since the deck 10 has a cross-shaped base structure in which the large pull 12 and the joists 13 are provided, the load applied to the deck material 14 is once received by the joists 13 and transmitted from the joists 13 to the large pulls 12. Is done. For this reason, if it is the deck 10 of the magnitude | size about this embodiment, what is necessary is just the number which supports the both ends of the large pull 12 as the bundle pillar 11, and can reduce the number of bundle pillars 11 and the number of bundle foundations. . Therefore, the construction period for constructing the bundle foundation can be shortened, and the construction cost can be reduced accordingly. In the case of cold districts, it is necessary to dig deeply to the freezing depth to install or drive, and the time and cost will be increased, but the deck 10 that requires a small number of bundle foundations has such a problem. This is particularly effective in cold regions.

(8) In addition, when a large number of pipes are buried around the building, the bundle foundation may interfere with the pipes due to the large number of bundle foundations. In this case, it is necessary to shift the bundle foundation, and the construction cannot be performed according to the recommended dimensions. However, in the deck 10, since the number of bundle foundations can be reduced, there is little possibility of interference between the bundle foundations and piping, and the positions of the bundle pillars 11 can be constructed at recommended intervals.

(9) Further, since the parallelism of the joists 13 is sufficiently ensured, a situation in which the deck material 14 is installed between the joists 13 that are spaced more than necessary is not caused. For this reason, the deck material 14 does not bend excessively due to the vertical load applied to the deck material 14, and durability can be improved.

(10) Further, in the deck 10, the longitudinal direction of the pulling 12 and the longitudinal direction of the deck material 14 are the same, so that the deck material 14 warps when the deck material 14 is bent or when the deck material 14 is thermally stretched by direct sunlight. In contrast, it can be reliably counteracted by the large pull 12, and there is no need to reinforce the bundle pillars 11 by connecting them with roots, so that the work of attaching the roots and the cost of the members can be eliminated.

In addition, this invention is not limited to the thing of the structure demonstrated by the above embodiment, The modification in the range which can achieve the objective of this invention is contained in this invention.
For example, in the above-described embodiment, the attachment 15 is disposed between the vertical pieces 13C forming the fixed piece 13B of the joist 13, and the fixed piece 13B is fixed to the joist 13, but separately from such a fixed piece 13B. Vertical strips may be provided on the joists, and the attachment 15 may be disposed between the strips.

  In the said embodiment, although the locking piece 15B was provided in the attachment 15, even when it is a simple rectangular plate in which such a locking piece is not provided, it is contained in this invention. However, since the effect (4) described above can be obtained by having such a locking piece, it is desirable to provide the locking piece.

In the deck 10 described in the above embodiment, the joist 13 is bridged in a direction substantially orthogonal to the large pull 12, so that the attachment 15 has a rectangular shape, and an angle between a pair of guide portions 15C and an adjacent side. Was formed at a substantially right angle.
On the other hand, in the present invention, the joist may be bridged at an arbitrary angle with respect to the large pull. In such a case, the angle between the pair of guide portions and the adjacent side may be formed at the arbitrary angle, and the effects of the present invention can be obtained in the same manner. That is, in the present invention, the shape of the attachment is not specified, and it is only necessary to guide the movement of the joist in the longitudinal direction by, for example, making the pair of guide portions parallel to each other.
