Description

[Technical field]

[0001] The present invention relates to a deck structure having a support frame and support beams that support a deck material. [Background technology]

[0002] 2. Description of the Related Art When laying multiple deck materials on a terrace, balcony, veranda, etc., a structure in which the deck materials are supported by multiple support frames and support beams is known. For example, in Patent Document 1, joists (vertical members) with a hat-shaped cross section that protrude upward are fixed to the support beam (base part), and further upward-protruding hat-shaped cross-section joists (horizontal members) are fixed in a criss-cross pattern so that they intersect at right angles to the joists, and then deck material is laid on top of the joists. The support beam and the joist are aligned with a pair of outer pieces located below the joist on a plate (base plate) attached to the support bolt (anchor bolt) of the support beam, and each of these outer pieces is fixed to the plate with a screw or the like. A similar structure is also disclosed in Patent Document 2, but there is a demand for a deck structure that is easier to assemble. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2017-2706 A [Patent Document 2] Utility Model Registration No. 3211773 Summary of the Invention [Problem to be solved by the invention]

[0004] The present invention aims to provide a deck structure having a plurality of support frames and support beams for supporting a plurality of deck materials, which has superior workability and strength. [Means for solving the problem]

[0005] The deck structure of the present invention is a deck structure comprising a plurality of support frames and support bundles which support a plurality of deck materials, wherein the cross-sectional structure of the support frame has a horizontal portion, a pair of side portions vertically disposed on both ends of the horizontal portion, and an opening which opens between the pair of side portions, the support bundle has a support bolt which passes through the horizontal portion, and a clamping member which is attached to the support bolt and clamps the horizontal portion, and the support frame which is fixed to the support bundle has the opening located on the upper side.

[0006] Here, the support frame is an elongated body having an opening in its cross-sectional structure, such as a generally U-shaped or hat-shaped cross-section. The support frame has a horizontal portion on the lower side when the opening is located on the upper side. Such a support frame may be, for example, an aluminium extrusion. On the other hand, the support bundle has, for example, a support bolt protruding upward from the bottom placed on the foundation concrete, a clamping member attached to this support bolt, for example a plate, and a fixing member such as a nut screwed onto the above of this plate. In the present invention, when fixing the support frame to the support bundle, the support bolt is inserted through the horizontal portion of the support frame, and the fixing member is tightened with the horizontal portion placed on a plate, for example. This causes the horizontal portion to be sandwiched between the plate and the fixing member. In this case, since the opening of the support frame is located on the upper side, the fixing member can be screwed and tightened onto the support bolt through the opening, allowing for smooth fixing work.

[0007] In the present invention, the side portion of the support frame may have a hollow cross-sectional shape. A support frame having sides with a hollow cross-sectional shape in this manner has excellent strength for stably supporting the deck material.

[0008] In the present invention, the end portion of the support frame may be fixed to the support bundle in a state where it is embraced by a joint member or a terminal member. By having the ends of the support frame embraced by the joint members and the terminal members in this manner, it becomes easier to prevent the sides of the support frame from opening outward when subjected to a load, for example. In addition, by fixing the support frame to the support bundle via a joint member or the like, the strength of the support structure is also improved.

[0009] Furthermore, in the present invention, the support frame may consist of a joist fixed to the support bundle with the opening positioned at the upper side and a floor joist fixed to the joist with the opening positioned at the lower side, and the side of the support frame may have a flange portion at the end, and the joist and the floor joist may be attached so that their flange portions intersect each other at right angles. In the present invention, the joists and beams that constitute the supporting frame may be of the same shape, and they can be used differently by inverting the positions of their openings vertically. By fixing the joists and beams in a crisscross pattern so that they intersect at right angles to each other, the strength of the support structure that holds the deck material can be increased. In this case, the fixing operation can be easily performed by utilizing the flanges on the sides of the joists and the beams and fixing the flanges together using, for example, screws. Effect of the Invention

[0010] The deck structure of the present invention is easy to assemble because the support bolts of the support bundles can be used to fix the support frame to the support bundles, and the fixing work can be performed through openings located on the upper side of the support frame. Furthermore, for example, the sides of the support frame may have a hollow cross-sectional shape, providing a stronger deck structure. [Brief description of the drawings]

[0012] An example of a deck structure according to the present invention will now be described with reference to the drawings. The present invention is a deck structure that supports a plurality of deck materials 40 using a support frame including a plurality of support beams 10, a plurality of joists 20, floor joists 30, and base materials. There is no limit to the number of support beams, support frames, and deck materials, and they can be selected appropriately according to the construction location, purpose, etc.

[0013] 1(a) and (b) show a portion of an example of the structure of one support beam 10 and a joist 20 that constitute a deck structure, and a deck material 40. In FIG. The support bundle 10 has a support bolt 12 protruding upward from a bottom portion 11 , a plate 13 that can be attached to the support bolt 12 , and a fixing member that can be attached to the support bolt 12 above the plate 13 . The fixing members include a washer member 14 such as a spring washer, and a nut member 15. The bottom 11 in this embodiment is an example of a circular steel plate, and the steel plate may be a hot-dip zinc alloy plated steel plate or the like, but there is no limitation on the shape or material. The bottom 11 may be fixed to a concrete foundation using anchor bolts, or may be covered on the outside with an elastic member 16 such as rubber so that it can be placed on a concrete foundation, as shown in Figs. It is preferable to select the length of the support bolt 12 according to the target height of the deck material or support frame to be placed above, and the screwed state of the bottom 11, which can be screwed onto the support bolt 12, which is a cut bolt, may be fixed with a nut 11a, but the support bolt and the bottom may also be of an integrated structure. The plate 13 in this embodiment is a circular steel plate having a screw portion 13a that can be screwed onto the support bolt 12, and the height of the plate 13 relative to the support bolt 12 can be adjusted by rotating the plate 13. In this embodiment, a plate, a washer member, and a nut member are used as the clamping members, but as long as the horizontal part of the joist described below can be held on the support bolt, for example, the plate can support the horizontal part from below, and there is no particular limitation. In addition, in the case of a plate without a screw-fastening portion, the height of the plate may be determined by placing the plate on a nut or the like that has already been screwed onto the support bolt.

[0014] The cross-sectional structure of the beam 20 includes a horizontal portion 22, a pair of side portions 23, 23 extending vertically upward from both ends thereof, and an opening 21 opening between these side portions. The opening 21 is formed along the longitudinal direction of the beam 20. For example, if the horizontal portion 22 and the side portion 23 are integrally extruded, the opening 21 can be easily formed. The beam 20 in this embodiment is an example in which its side portion 23 has an outer wall 23a that is approximately perpendicular to the horizontal portion 22, as shown in Figure 1 (b), and an outer piece 23b and an inner piece 23c as flange portions at its upper end, and the area between the inner pieces 23c, 23c of the pair of side portions forms an opening 21. The outer piece 23b protrudes outwardly from the outer wall 23a approximately horizontally, and the inner piece 23c protrudes inwardly. In addition, the side portion 23 of the beam 20 may have a hollow cross-sectional shape. For example, FIG. 3(c) shows an example of a hollow cross-sectional shape in which the side portion 23 has a hollow portion 23d. The hollow portion 23d is formed by connecting the inner piece 23c and the horizontal portion 22 to an inner wall 23e that is approximately perpendicular to the horizontal portion 22. There is no limitation to the cross-sectional shape of the hollow, and for example, the hollow may have two or three hollow portions arranged vertically. In this embodiment, the horizontal portion 22 and the side portion 23 are made of aluminum and are integrally formed, but there is no limitation to the material. In addition, the longitudinal direction of the rail 20 may be cut to the desired size, and there is no limit to the length.

[0015] As shown in FIG. 1( a ), the deck material 40 has a bottom surface to be placed on the joists 20 or the like, a top surface, and left and right side surfaces 41 , 42 . The side surfaces 41, 42 may be asymmetrical. For example, one side surface 41 may have a protrusion 41a extending outward along the bottom surface. There is no limitation on the material of the deck material 40, and it may be made of wood, resin, artificial wood, or the like. As shown in FIG. 7, the plate may be lightweight due to a hollow cross-sectional shape consisting of a plurality of ribs 40a, and may have various designs such as stripe grooves or irregularities on the upper surface.

[0016] A method of fixing the support bundle 10 and the beam 20 will be described with reference to FIG. The horizontal portion 22 of the beam 20 is provided with a bolt insertion hole 22a into which the support bolt 12 can be inserted. The support bolt 12 with the plate 13 attached thereto is inserted into this bolt insertion hole 22 a, and the horizontal part 22 of the beam is placed on the plate 13 . The bolt insertion holes 22a can be provided in the horizontal portion 22, for example, through the opening 21, and may be provided after the joists are cut to the desired dimensions. It is preferable to adjust the height of the joists using a laser marking device or the like. For example, a laser receiver is placed on the outer and inner pieces 23b, 23c of the joists, and the plate 13 is rotated relative to the support bolt 12 to adjust the height. Thereafter, the washer member 14 and the nut member 15 are attached to the support bolt 12 passing through the horizontal portion 22 through the opening 21, and then tightened. This allows the beams 20 to be fixed to the support bundle 10.

[0017] 3(a) to (c) show an example in which two joists 20, 20 are connected using a joint member 50. In FIG. The joint member 50 is an example of a steel plate having a generally U-shaped cross section, in which a bottom wall 51 and a pair of side walls 52, 52 standing on both ends of the bottom wall 51 are integrally formed. As shown in FIG. 3(b), the bottom wall 51 is provided with a bolt through hole 51a at approximately the center thereof, through which the support bolt 12 can pass. Further, the side wall 52 is provided with fixing holes 52a facing the respective outer walls 23a of the beams 20, and screw members 53 such as self-drilling screws can be inserted into these fixing holes 52a. In a specific connection method, first, the bottom wall 51 of the joint member 50 is placed on the plate 13 of the support bundle 10 . At this time, the support bolt 12 passes through the bolt through hole 51 a provided in the bottom wall 51 . Next, for the joists 20 to be connected, a semicircular hole corresponding to the support bolt 12 is provided at the end of the horizontal part 22 facing the other joist, and the two joists 20, 20 are placed on the bottom wall 51 of the joint member so that this semicircular hole is aligned with the support bolt 12. All that remains is to use the washer member 14 and the nut member 15 to nut-tighten the support bolt 12, and the screw member 53 is used to screw-tighten the side wall 52 of the joint member and the outer wall 23a of the joist. This allows the support bundle 10, the joint member 50 and the two beams 20, 20 to be fixed in place.

[0018] Here, among the ends of the joists, the end that is not connected to other joists is referred to as the terminal portion 20a, and Figure 4 shows an example in which this terminal portion 20a is fixed to the support bundle 10 via a terminal member 60. The terminal member 60 is an example of a hot-dip zinc alloy plated steel sheet having a substantially U-shaped cross section with a pair of side walls 62, 62 erected on both ends of a bottom wall 61. The bottom wall 61 is provided with a bolt through hole (not shown) through which the support bolt 12 can pass. The support bolts 12 of the support bundle are inserted into the bolt through holes and bolt insertion holes 22a of the terminal member 60 and the terminal portion 20a, respectively, and the bottom wall 61 and the horizontal portion 22 are stacked on the plate 13, and then a nut member 15 or the like is tightened onto the support bolts 12. As a result, the terminal portion 20a of the beam is fixed to the support bundle 10 via the terminal member 60. In this manner, when the terminal portion of the joist is embraced by the terminal member, it becomes easier to prevent the side portion 23 of the joist from opening outward.

[0019] As shown in Figures 5 and 6, the deck material may be fixed to the joists etc. using deck fasteners. The deck fixture 45 of this embodiment is an example of a resin molded product having a substantially T-shaped cross section, which has a pressing portion 45a that abuts against the protruding piece 41a of the deck material 40, and a pair of locking portions 45b, 45b on both sides of the pressing portion 45a. The pressing portion 45a has a fixing hole 45c formed approximately in the center thereof. There are no particular limitations on the shape or material of the deck fastener. As shown in FIG. 5, the multiple deck materials 40 are laid generally parallel to each other so as to intersect with the joists 20 at approximately right angles. At this time, the protrusion 41 a provided on the side surface of the deck material 40 can be fixed to the flange portion of the joist 20 using a deck fixing tool 45 and a screw member 46 . For example, as shown in FIG. 6, a pressing portion 45a of a deck fixing device 45 may be disposed on a protruding piece 41a of the deck material, and a screw member 46 may be inserted into a fixing hole 45c and passed through the protruding piece 41a to be screwed to an inner piece 23c of the rail. In this way, by using deck fixing devices to screw the inner pieces of the joists, it becomes easier to prevent the sides of the joists from opening up, and even if a joist 20 with a short vertical length of the side 23 is used, as shown in Figure 6, a low-floor design with excellent strength can be achieved. Each of the multiple deck materials 40 has an engaged portion on its side that corresponds to the engaging portion 45b of the deck fastener, making it possible to engage adjacent deck materials via one deck fastener.

[0020] FIG. 7 shows an example of a deck structure in which joists 30 are fixed onto beams 20 fixed to a plurality of support beams 10 to support deck material 40. On the joists 20, joists 30 are fixed in a criss-cross pattern so as to intersect at approximately right angles, and on these joists 30, a plurality of deck materials 40 are laid generally parallel to each other so as to intersect at approximately right angles. FIG. 8 shows one support beam 10, joists 20, and floor joists 30 that constitute this deck structure example, as well as a portion of the deck material 40. The method of fixing the beams 20 to the support bundle 10 is as described above. The joist 30 has a cross-sectional structure including a horizontal portion 32, a pair of side portions 33, 33 extending downward from both ends thereof, and an opening 31 opening between the side portions. The opening 31 is formed along the longitudinal direction of the joist 30 . The common joist 30 in this embodiment is an example of a hollow cross-sectional shape in which the side portion 33 has a hollow portion 33d, but is not limited to this shape. The side portion 33 has an outer wall 33a that is approximately perpendicular to the horizontal portion 32, and an outer piece 333b and an inner piece 33c that serve as flanges at its lower end, and a hollow portion 33d is formed by the horizontal portion 32, the outer wall 33a, the inner piece 33c, and an inner wall 33e that is approximately perpendicular to the inner piece 33c. In this embodiment, the joists are an example of extruded aluminum material, but there is no limitation to the material. In addition, in this example, the cross-sectional structures of the joists and the beams are the same shape but inverted vertically, but the cross-sectional structures of each may be different shapes. As shown in FIG. 9(a), the joist 30 is disposed relative to the beam 20 so that its outer piece 33b intersects with the flange portion (outer and inner pieces 23b, 23c) at a right angle, and can be fixed using a screw member 34. For example, as shown in FIG. 9(b), it may be fixed to the inner piece 23c of the joist with a screw. Additionally, the deck material 40 may be fixed to the horizontal portion 32 of the joists using deck fasteners 45, for example. [Explanation of symbols]
