JP 2005-097875 A

By the way, in the joist described in Patent Document 1, the amount of protrusion from the joist of the steady rest is adjusted only by adjusting the position of the locking nut with respect to the screw shaft. It is difficult to maintain a fixed state according to the change in the length dimension of the joist.
That is, when the joist contracts due to a decrease in the outside air temperature, the pressing force from the steady rest against the inner wall surface of the fixed frame is weakened, and the joist itself may be displaced. For this reason, it is difficult to suppress deformation such as warping of the deck by joists. On the other hand, when the joist extends due to a rise in the outside air temperature, an excessive pressing force may be applied to the inner wall surface of the fixed frame.

  An object of the present invention is to provide a deck support material, a deck and a deck construction method that can maintain a fixed state even when the outside air temperature changes.

  The deck support material of the present invention is a deck support material that is fixed between a pair of wall portions and supports the deck material, and a support main body that is disposed with the opposing direction of the pair of wall portions as a longitudinal direction, and the support A slide member attached to one end of the main body so as to be slidable along the longitudinal direction of the support main body, and a spring member for biasing the slide member toward one of the pair of wall portions; , A length adjuster attached to at least one of the other end of the support body and the slide member, and either the other end of the support body and the slide member or the length adjustment. And a pair of abutting members attached to the tool and abutting against the pair of wall portions.

According to the deck support material of the present invention, the overall length of the deck support material can be adjusted by adjusting the length of the length adjuster, and the slide member is urged toward the one wall by the spring member. Even if the length of the support body such as resin or wood changes in response to changes in the outside air temperature, the slide member slides along the longitudinal direction of the support body in response to the change in the outside air temperature. By elastically expanding and contracting, the fixed state of the deck support material can be kept constant. That is, when the support main body contracts due to a decrease in the outside air temperature, the slide member biased by the spring member slides toward one wall portion, so that the total length of the deck support material can be extended. Can be prevented from being loosened to the extent that the fixing to the wall portion causes positional displacement. In addition, when the support body is extended due to a rise in outside air temperature, the slide member slides toward one end of the support body against the bias of the spring member, thereby reducing the overall length of the deck support material. It is possible to suppress an excessive pressing force from being applied to the pair of wall portions.
Furthermore, the tension force on the pair of wall portions can be adjusted by adjusting the length of the length adjusting tool.
When the length adjuster is attached to the other end of the support body, the position of the support body in the longitudinal direction can be adjusted by adjusting the length of the length adjuster, and the degree of installation freedom can be expanded.
On the other hand, when the length adjuster is attached to the slide member, the length of the support body is maintained in the longitudinal direction by adjusting the length while the deck support member is stretched and fixed between the pair of wall portions. The position of the slide member relative to the support body can be adjusted as it is, and the pressing force against the pair of wall portions can be adjusted.
Note that the deck support member is constituted by, for example, joists to which the deck is fixed.

In the deck support material of the present invention, the length adjuster includes a first length adjuster attached to the other end of the support body, and a second length adjuster attached to the slide member, One abutting member of the pair of abutting members is attached to the first length adjuster, and the other abutting member of the pair of abutting members is attached to the second length adjuster. It is preferable that a contact member is attached.
According to such a configuration, the amount of protrusion of the one abutting member with respect to the other end of the support body can be adjusted by adjusting the length of the first length adjustment tool. The second length adjuster can be used for adjusting and adjusting the overall length of the deck support material. On the other hand, the length of the second length adjuster can be adjusted to adjust the amount of protrusion of the other abutting member relative to the slide member. It can be used for adjusting the urging force, and the workability can be improved by properly using each length adjuster. Furthermore, since both the first length adjustment tool and the second length adjustment tool are provided, the adjustment width can be easily increased.

In the deck support material of the present invention, a long hole extending in the sliding direction is formed in one of the slide member and the support main body, and the long hole is formed in the other of the slide member and the support main body. It is preferable that a guide body to be guided is formed, and the guide body is inserted into the elongated hole so as to suppress an inclination of the slide member with respect to the support body.
According to such a configuration, since the guide body is inserted into the long hole so as to suppress the inclination of the slide member with respect to the support body, it is possible to suppress the floating of the deck support member due to the inclination of the slide member with respect to the support body.

In the deck support material of the present invention, it is preferable that the guide body is constituted by two or more guide screws positioned side by side in the slide direction.
According to such a configuration, the configuration of the guide body can be simplified with two or more guide screws, and the two or more guide screws are arranged side by side in the slide direction, so that the inclination of the slide member with respect to the support body is increased. Can be suppressed.

In the deck support material of the present invention, it is preferable that the slide member is provided with a mark indicating a position in the slide direction with respect to the support body.
According to such a configuration, since the mark indicating the position in the slide direction with respect to the support body is provided on the slide member, the position of the slide member can be adjusted while confirming the position of the slide member in the slide direction with respect to the support body by the mark. For example, the urging force of the spring member can be easily set to a predetermined set value.

In the deck support material of the present invention, it is preferable that the deck support material further includes a height adjuster capable of adjusting a downward protrusion amount from the support body.
According to such a configuration, since the height adjustment tool capable of adjusting the downward protrusion amount from the support main body is provided, for example, a panel material for height position adjustment or the like is not installed at the lower portion of the deck support material. However, the height adjustment tool can easily adjust the height position of the deck support material to an appropriate height position.

The deck of the present invention comprises the deck support material of the present invention described above and a deck material fixed to the deck support material.
According to the deck of this invention, it can be set as the deck which can exhibit the effect similar to the deck support material of this invention mentioned above. Therefore, even if the outside air temperature changes after the deck material is fixed to the deck support material, the deck support material can be kept fixed to the pair of walls, so that the deck material may be misaligned, lifted, or tilted. Can be eliminated.

[Deck construction]
Hereinafter, the construction procedure of the deck 1 will be described.
First, as shown in FIG. 1, a plurality of joists 3 are arranged at predetermined intervals along the frontage direction. At this time, the longitudinal direction of each joist 3 is the same as the protruding width direction of the balcony 4, the contact member 62 is located on the wall 6 side (front end side) of the balcony 4, and the contact member 72 is the balcony 4 is located on the wall 7 side (base end side). The contact member 72 is in contact with the wall 7.
Here, as shown in FIG. 2, the bottom part 5 of the balcony 4 is provided with a downward slope from the wall part 7 toward the wall part 6. Each of the shaft members 81 is adjusted by adjusting each of the shaft members 81 so that the joists 3 extend in the horizontal direction.

  Next, the total length of each joist 3 is adjusted by adjusting the length of the length adjuster 60 and temporarily fixed between the wall portions 6 and 7. That is, the protruding amount of the shaft member 61 is adjusted by rotating the operation nut 63, and the contact member 62 is protruded toward the wall portion 6 along the longitudinal direction of the joist body 30 (see FIG. 6). Abut. Subsequently, the locking nut 64 is rotated to come into contact with the connecting plate portion 363 of the fixing bracket 36 to lock the rotation of the shaft member 61. In this way, the joists 3 are temporarily fixed between the wall portions 6 and 7.

  Next, by adjusting the length of the length adjuster 70, the tension state of the joists 3 with respect to the wall portions 6 and 7 is adjusted. That is, the amount of protrusion of the shaft member 71 is adjusted by rotating the operation nut 73, the slide member 40 is moved toward the joist body 30 in the sliding direction, and the end 30 </ b> B side of the joist body 30 is located between the two marks 45.

Are fixed to both end portions 30A and 30B.
In this way, the deck 1 is constructed on the balcony 4.

[Effect of this embodiment]
(1) Since the length adjusters 60 and 70 are provided, the total length of the joist 3 can be adjusted when the joist 3 is installed between the pair of wall portions 6 and 7, and the slide is slidable with respect to the joist main body 30. Since the slide member 40 is biased toward the wall portion 7 by the coil spring 50 interposed between the member 40 and the fixing bracket 37 provided at the end 30B of the joist main body 30, the aluminum joist main body Even if the length dimension of 30 changes in response to a change in the outside air temperature, the slide member 40 slides along the longitudinal direction of the joist body 30 in response to the change in the outside air temperature, and the coil spring 50 elastically expands and contracts. Thus, the fixed state of each joist 3 can be kept constant. That is, when the length of the joist main body 30 is reduced due to the temperature drop of the outside air temperature, the slide member 40 biased by the coil spring 50 slides toward the wall portion 7, thereby extending the overall length of the joist 3. It is possible to prevent the fixing to the wall portions 6 and 7 from being loosened to the extent that misalignment occurs. Further, when the length dimension of the joist body 30 is increased due to the temperature rise of the outside air temperature, the slide member 40 slides toward the end 30B of the joist body 30 against the bias of the coil spring 50, The overall length of the joist 3 can be shortened, and an excessive pressing force can be suppressed from being applied to the wall portions 6 and 7.
Furthermore, the tension force with respect to the walls 6 and 7 can be adjusted by adjusting the lengths of the length adjusters 60 and 70.
Moreover, the position in the longitudinal direction of the joist body 30 can be adjusted by adjusting the length of the length adjuster 60, and the degree of freedom in installation can be expanded.
On the other hand, the joist body 3 of the slide member 40 is maintained while maintaining the position of the joist body 30 in the longitudinal direction by adjusting the length with the length adjusting tool 70 in a state where the joist 3 is stretched and fixed between the wall portions 6 and 7. The position with respect to 30 can be adjusted, and the pressing force on the walls 6 and 7 can be adjusted.

(4) Since the structure of the connecting bodies 55A and 55B can be simplified by the two stepped screws 551 and 552, and the stepped screws 551 and 552 are arranged side by side in the sliding direction, the inclination of the slide member 40 relative to the joist body 30 Can be suppressed.
(5) Since the mark 45 indicating the position in the slide direction with respect to the joist body 30 is provided on the slide member 40, the position of the slide member 40 is adjusted while confirming the position of the slide member 40 in the slide direction with respect to the joist body 30 by the mark 45. Thus, the biasing force of the coil spring 50 can be easily set to a predetermined set value.
(6) Since the height adjuster 80 is attached to the joist main body 30, for example, the height adjuster 80 can be used without installing a panel member for height position adjustment (not shown) or the like in the lower part of the joist 3. The height position of the joist 3 can be easily adjusted to an appropriate height position.
(7) In the construction of the deck 1, first, the length of the joist 3 is adjusted by adjusting the length of the length adjuster 60, and the abutting members 62, 72 are brought into contact with the walls 6, 7. The fixing position of the joist 3 can be set (temporarily fixed) without applying a large pressing force to 7.
Furthermore, since the slide member 40 is slid with respect to the joist body 30 by adjusting the length of the length adjusting tool 70, the coil spring 50 is kept in the fixed position of the joist 3 without changing the position of the joist body 30. The biasing force can be set to a set value.
Thus, workability can be improved by using the length adjuster 60 for adjusting the overall length of the joist 3 and using the length adjuster 70 for adjusting the urging force of the coil spring 50.
