Description

[Technical Field]

[0001] The present invention relates to a method for installing deck plates and ceiling finishing wood boards on beams. [Background technology]

[0002] The method using deck plates is known as a rational method for the foundation of externally insulated dry roofs, which does not require concrete pouring, as it is lightweight and shortens the construction period. Furthermore, the method using composite deck slabs, which are formed by integrating deck plates and concrete, is widely used as a standard floor construction method for steel-framed buildings due to its ease of construction and cost-effectiveness (see, for example, Patent Document 1). Such roof foundation deck plates and composite deck slabs often require a ceiling finish. Therefore, a known method involves installing wooden boards for ceiling finishes attached to the deck plates in advance. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2020-41348 Summary of the Invention [Problem to be solved by the invention]

[0004] However, if the ceiling finishing wooden boards are fastened to the deck plate in advance, the weight is too heavy for manual installation at the construction site, making work difficult and cumbersome.

[0005] The present invention has been made in consideration of the above-mentioned problems, and aims to provide a rational method for installing deck plates and ceiling finishing wood boards on beams in order to improve the convenience of the work process during construction. [Means for solving the problem]

[0006] According to one embodiment of the present invention, the above problem is solved by a method for installing a deck plate and a ceiling finishing wood board on a beam, the method including the steps of: installing a wood board between two adjacent beams using a positioning member for positioning the wood board relative to the beam; placing the deck plate on top of the wood board; and joining the wood board and the deck plate.

[0007] According to this, by using the positioning member, it is possible to easily position the wooden board relative to the beam. Also, by using the positioning member, it is possible to reliably prevent the wooden board from falling off when installing the wooden board on the beam. Furthermore, since the deck plate and the wooden board can be installed in separate processes, the workload is reduced and manual installation is easier.

[0008] The positioning member may be a member having a U-shaped cross section and attached in advance to the upper surface of the upper flange of the beam, and the height of the positioning member may be equal to or greater than the height of the wood board.

[0009] This allows the deck plate to be joined to the positioning member without interfering with the wooden board when it is placed on top of the wooden board. It also allows for the installation of wide wooden boards across the entire distance between the beams, improving the efficiency of the installation of wooden boards.

[0010] The positioning member may be a member having an L-shaped cross section, the vertical portion of which is attached in advance to the end face of the upper flange of the beam, and the height of the vertical portion may be equal to or greater than the height of the wooden board.

[0011] This allows the deck plate to be joined to the upper flange of the beam without interfering with the wooden board or the positioning member when the deck plate is placed on the wooden board. Also, because the wooden board is placed below the upper surface of the upper flange of the beam, it is possible to prevent the thickness of the roof or floor from increasing by the height of the wooden board.

[0012] The positioning member may be an L-shaped member or a flat member in cross section, and may be attached in advance to both ends of the wood board so that the upper surface of the wood board is flush with the upper surface of the upper flange of the beam during the process of installing the wood board.

[0013] This allows the wooden boards to be placed below the upper flanges of the beams when the deck plate is placed on top of them, preventing the roof or floor from becoming thicker by the height of the wooden boards. Also, because the positioning members are attached to both ends of the wooden boards in advance, it is not necessary to join the positioning members to the beams, further improving construction efficiency at the construction site.

[0014] The deck plate is preferably formed from peaks and valleys extending in the longitudinal direction of the beam.

[0015] In the step of placing the deck plate on the wooden board, it is preferable that the dimensions of the deck plate and the positioning member are set so that the inclined portion forming the peak of the deck plate abuts against the horizontal portion of the positioning member.

[0016] This allows the height of the lower surface of the deck plate's valleys to be aligned with the upper surface of the beam's upper flange, enabling the deck plate to be directly joined to the beam. Furthermore, when placing the deck plate on the wooden board, the inclined portions of the deck plate's peaks abut against the horizontal portions of the positioning members, thereby serving as a guide for positioning the deck plate relative to the beam. This further improves construction efficiency at the construction site.

[0017] It is preferable that the deck plate extends between two or more beams in the short-side direction of the beams.

[0018] According to this, the deck plate is continuously supported between two or more beams, thereby improving the efficiency of deck plate construction.

[0019] The installation method may further include the step of joining a heat insulating material and a waterproofing material onto the deck plate.

[0020] Instead of joining the insulation material and the waterproofing material, the installation method may further include pouring concrete onto the deck plate to form a composite deck slab. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0022] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that in the following description, the drawings are schematic, and the dimensional relationships and ratios of elements may differ from the actual ones. The dimensional relationships and ratios may differ between the drawings.

[0023] 1 is a front view of a ceiling-finished roof underlayment deck plate according to a first embodiment of the present invention. The roof underlayment deck plate comprises a positioning member 20, a wooden board 30, a deck plate 40, a heat insulating material 50, and a waterproofing material 60. The beam 10 is a member having an I-shaped cross section and extending in the depth direction in the figure. The upper flange 12 of the beam 10 has an upper surface 12b and end surfaces 12a on both sides thereof.

[0024] The positioning member 20 according to this embodiment has a U-shaped cross section. The positioning member 20 may be attached to the upper surface 12b of the upper flange 12 of the beam 10 in advance, or may be attached to the upper surface 12b of the upper flange 12 of the beam 10 when the wooden board 30 is installed, i.e., at an appropriate time at the construction site, etc. The attachment method may be welding, etc.

[0025] The wooden board 30 is a plank-shaped wooden board intended primarily for enhancing the aesthetic appearance of the ceiling and improving fire resistance. The wooden board 30 may be made of not only sawn lumber but also wood materials, such as engineered wood such as laminated lumber or LVL, which has been treated with chemicals or added with resin to improve its strength, fire resistance, flame retardancy, or both. It may also be treated to improve its resistance to mold and decay fungi.

[0026] The deck plate 40 is a corrugated steel plate formed by roll-forming or the like from a thin steel plate that has been surface-treated, such as by galvanizing. Note that the steel plate does not necessarily have to be surface-treated. In this embodiment, the deck plate 40 is formed from peaks 40a and valleys 40b that extend in the short direction of the beam 10 (the horizontal direction in FIG. 1). However, the deck plate 40 may also be a flat deck plate with ribs formed on a flat plate, or a reinforcing bar deck plate with a reinforcing bar truss attached.

[0027] The heat insulating material 50 and the waterproofing material 60 are usually provided on a roof underlayment deck plate, and are attached to the deck plate 40 in the order of the heat insulating material 50 and the waterproofing material 60. The heat insulating material 50 and the waterproofing material 60 may be fastened to the deck plate 40 with screws, bolts, adhesive, or the like.

[0028] The method for installing the deck plate 40 and the wooden boards 30 in this embodiment will be described below. First, the positioning members 20 for positioning the wooden boards 30 relative to the beams 10 are attached to the upper surfaces 12b of the upper flanges 12 of each beam 10, for example, by welding. Next, the wooden boards 30 are placed between the positioning members 20 of two adjacent beams 10. At this time, the wooden boards 30 do not need to be fastened to the upper flanges 12 of the beams 10 because the support from the upper surfaces 12b of the upper flanges 12 of the beams 10 reliably prevents the wooden boards 30 from falling off. Next, the deck plate 40 is placed on top of the wooden boards 30, and the deck plate 40 is fastened to the wooden boards 30 and the positioning members 20 by screws, bolts, welding, adhesive, or the like. At this time, the support from the upper surfaces 12b of the upper flanges 12 of the beams 10 reliably prevents the wooden boards 30 from falling off, so the deck plate 40 does not need to be fastened to the wooden boards 30. Finally, the heat insulating material 50 and the waterproof material 60 are placed on the deck plate 40 and fastened to the deck plate 40 with screws, bolts, adhesive, or the like.

[0029] In this embodiment, the height of the positioning member 20 is set to be equal to or greater than the height of the wooden board 30. This allows the deck plate 40 to be positioned anywhere in the lateral direction without interfering with the wooden board 30 and the positioning member 20, so the deck plate 40 can be extended between two or more beams, i.e., the deck plate 40 can be continuously supported. The thickness of the finished roof underlayment deck plate is determined by the total thickness of the positioning member 20, deck plate 40, insulation material 50, and waterproofing material 60.

[0030] 2 is a front view of a ceiling-finished roof underlayment deck plate according to a second embodiment of the present invention. The roof underlayment deck plate includes a positioning member 21, wooden boards 30, a deck plate 40, a heat insulating material 50, and a waterproofing material 60. The beams 10, wooden boards 30, deck plate 40, a heat insulating material 50, and a waterproofing material 60 are the same as those in the first embodiment, so repeated explanations will be omitted.

[0031] The positioning member 21 according to this embodiment has an L-shaped cross section and includes a vertical portion 21a and a horizontal portion 21b. The vertical portion 21a of the positioning member 21 may be attached to the end surface 12a of the upper flange 12 of the beam 10 in advance, or may be attached to the end surface 12a of the upper flange 12 of the beam 10 when the wooden board 30 is installed, i.e., at an appropriate time at the construction site, etc. The attachment method may be welding, etc.

[0032] The method for installing the deck plate 40 and wooden boards 30 in this embodiment is described below. First, the positioning members 21 are attached to the end surfaces 12a of the upper flanges 12 of each beam 10. Next, the wooden boards 30 are placed between the vertical portions 21a of the positioning members 21 attached to two adjacent beams 10. At this time, the horizontal portions 21b of the positioning members 21 reliably prevent the wooden boards 30 from falling off, so it is not necessary to fasten the wooden boards 30 to the horizontal portions 21b. Next, the deck plate 40 is placed on top of the wooden boards 30, and the deck plate 40 is fastened to the wooden boards 30 and the upper surfaces 12b of the upper flanges 12 of the beams 10 with screws, bolts, welding, adhesives, or the like. At this time, the horizontal portions 21b of the positioning members 21 reliably prevent the wooden boards 30 from falling off, so it is not necessary to fasten the deck plate 40 to the wooden boards 30. Finally, the heat insulating material 50 and the waterproof material 60 are placed on the deck plate 40 and fastened to the deck plate 40 with screws, bolts, adhesive, or the like.

[0033] In this embodiment, the height of the vertical portion 21a of the positioning member 21 is sized to be equal to or greater than the height of the wooden board 30, so similar to the first embodiment, the deck plate 40 does not interfere with the wooden board 30 and the positioning member 21. Therefore, the thickness of the roof underlayment deck plate with a ceiling finish in this embodiment is smaller than the thickness of the roof underlayment deck plate in the first embodiment by the thickness of the positioning member 20. In addition, it becomes possible to directly join the deck plate 40 and the upper flange 12 of the beam 10.

[0034] 3(A) is a front view of a ceiling-finished roof underlayment deck plate according to a third embodiment of the present invention. The roof underlayment deck plate includes a positioning member 22, wooden boards 30, a deck plate 40, a heat insulating material 50, and a waterproofing material 60. The beams 10, wooden boards 30, deck plate 40, a heat insulating material 50, and a waterproofing material 60 are the same as those in the first embodiment, so repeated explanations will be omitted.

[0035] The positioning member 22 in this embodiment has an L-shaped cross section and includes a vertical portion 22a and a horizontal portion 22b. The vertical portions 22a of the positioning member 22 may be attached to both ends of the wooden board 30 in advance, or may be attached to both ends of the wooden board 30 when installing the wooden board 30, i.e., at an appropriate time such as at a construction site. The attachment method may be with screws, bolts, adhesive, or the like. The positioning member 22 is sized so that when the horizontal portion 22b of the positioning member 22 is placed on the beam 10, the upper surface of the wooden board 30 is flush with the upper surface 12b of the upper flange 12 of the beam 10.

[0036] The method for installing the deck plate 40 and wooden boards 30 in this embodiment will be described below. First, the positioning members 22 are attached to both ends of the wooden board 30. Next, the wooden board 30 is placed between the end faces 12a of the upper flanges 12 of two adjacent beams 10. At this time, the horizontal portions 22b of the positioning members 22 are placed on the upper faces 12b of the upper flanges 12 of the beams 10, reliably preventing the wooden board 30 from falling off, so it is not necessary to fasten the positioning members 22 to the upper flanges 12 of the beams 10. Next, the deck plate 40 is placed on top of the wooden board 30, and the deck plate 40 is fastened to the wooden boards 30 and the upper faces 12b of the upper flanges 12 of the beams 10 with screws, bolts, welding, adhesives, etc. At this time, the wooden board 30 is reliably prevented from falling off by the horizontal portion 22b of the positioning member 22 being placed on the upper surface 12b of the upper flange 12 of the beam 10, so it is not necessary to fasten the deck plate 40 to the wooden board 30. Finally, the heat insulating material 50 and waterproofing material 60 are placed on top of the deck plate 40 and fastened to the deck plate 40 with screws, bolts, adhesive, or the like.

[0037] FIG. 3(B) is a side view of the ceiling-finished roof underlayment deck plate shown in FIG. 3(A) as viewed in the direction of arrow S. When the deck plate 40 is formed of peaks 40a and valleys 40b extending in the short direction of the beam 10 as shown in FIG. 3(B), the horizontal portions 22b of the positioning members 22 are sized to fit within the peaks 40a of the deck plate 40. At least two positioning members 22 are allocated to one end of the upper flange 12 of the beam 10 along the longitudinal direction of the beam 10. In this case, if the width of the horizontal portions 22b is smaller than the width of the peaks 40a at the same height as the horizontal portions 22b, the deck plate 40 and the upper flange 12 of the beam 10 can be directly joined without mutual interference between the deck plate 40 and the positioning members 22. More preferably, the dimensions of the deck plate 40 and the positioning member 22 may be set so that, when the deck plate 40 is placed on the wood board 30, the inclined portions forming the peaks 40a of the deck plate 40 abut against the corners of the horizontal portions 22b of the positioning member 22. In this way, the deck plate 40 does not interfere with the positioning member 22, and the positioning member 22 acts as a guide to position the deck plate 40 relative to the beams 10 in the horizontal direction. Also, as with the second embodiment, the thickness of the ceiling-finished roof underlayment deck plate in this embodiment is smaller than the thickness of the roof underlayment deck plate in the first embodiment by the thickness of the positioning member 20.

[0038] 4(A) is a front view of a ceiling-finished roof underlayment deck plate according to a fourth embodiment of the present invention. The roof underlayment deck plate includes a positioning member 23, wooden boards 30, a deck plate 40, a heat insulating material 50, and a waterproofing material 60. The beams 10, wooden boards 30, deck plate 40, a heat insulating material 50, and a waterproofing material 60 are the same as those in the first embodiment, so repeated explanations will be omitted.

[0039] The positioning member 23 according to this embodiment is a flat member, and a portion of it may be attached to the upper surface of the wooden board 30 in advance, or may be attached to the upper surface of the wooden board 30 when installing the wooden board 30, i.e., at an appropriate time at the construction site, etc. The attachment method may be by screws, bolts, adhesive, etc.

[0040] The method for installing the deck plate 40 and the wooden boards 30 in this embodiment will be described below. First, the positioning members 23 are attached to both ends of the wooden board 30. Next, the wooden board 30 is placed between the end faces 12a of the upper flanges 12 of two adjacent beams 10. Since one end of the positioning member 23 is placed on the upper surface 12b of the upper flanges 12 of the beams 10, the wooden board 30 is reliably prevented from falling off. Therefore, the positioning member 23 does not need to be fastened to the upper flanges 12 of the beams 10. Next, the deck plate 40 is placed on the wooden board 30, and the deck plate 40 is fastened to the wooden board 30 and the upper surface 12b of the upper flanges 12 of the beams 10 with screws, bolts, welding, adhesive, or the like. Since one end of the positioning member 23 is placed on the upper surface 12b of the upper flanges 12 of the beams 10, the wooden board 30 is reliably prevented from falling off. Therefore, the deck plate 40 does not need to be fastened to the wooden board 30. Finally, the heat insulating material 50 and the waterproof material 60 are placed on the deck plate 40 and fastened to the deck plate 40 with screws, bolts, adhesive, or the like.

[0041] FIG. 4(B) is a side view of the ceiling-finished roof underlayment deck plate shown in FIG. 4(A) as viewed in the direction of arrow S. When the deck plate 40 is formed of peaks 40a and valleys 40b extending in the short direction of the beam 10 as shown in FIG. 4(B), the positioning member 23 is sized to fit within the peaks 40a of the deck plate 40. At least one positioning member 23 is allocated to one end of the upper flange 12 of the beam 10 along the longitudinal direction of the beam 10. In this case, if the width of the positioning member 23 is smaller than the width of the peaks 40a at the same height as the positioning member 23, the deck plate 40 and the upper flange 12 of the beam 10 can be directly joined together without mutual interference between the deck plate 40 and the positioning member 23. More preferably, the dimensions of the deck plate 40 and the positioning member 23 may be set so that, when the deck plate 40 is placed on the wood board 30, the inclined portions forming the ridges 40a of the deck plate 40 abut against the corners of the positioning member 23. In this way, the deck plate 40 does not interfere with the positioning member 23, and the positioning member 23 acts as a guide to position the deck plate 40 relative to the beams 10 in the horizontal direction. Also, as with the second and third embodiments, the thickness of the ceiling-finished roof underlayment deck plate in this embodiment is smaller than the thickness of the roof underlayment deck plate in the first embodiment by the thickness of the positioning member 20.

[0042] The above describes embodiments using the U-shaped positioning member 20, the L-shaped positioning members 21 and 22, and the flat-plate-shaped positioning member 23. However, the shapes of these positioning members 20, 21, 22, and 23 are merely examples, and embodiments using positioning members of other shapes suitable for positioning the wood board 30 relative to the beam 10, such as a Z-shape, are also contemplated.

[0043] Although not shown, the deck plate 40 may be formed from peaks 40a and valleys 40b extending in the longitudinal direction of the beam 10. In this case, the horizontal portion 22b of the positioning member 22 according to the third embodiment and the positioning member 23 according to the fourth embodiment are sized to fit within the peaks 40a of the deck plate 40 along the longitudinal direction of the beam 10. The positioning member 22 or 23 may be formed as a single member extending in the longitudinal direction of the beam 10.

[0044] Although not shown in the figure, concrete can be poured onto the upper side of the deck plate 40 in place of the heat insulating material 50 and the waterproofing material 60 to form a composite deck slab. Such a composite deck slab is used as the floor of a building.

[0045] Furthermore, when installing multiple wooden boards 30 along the depth direction of the beam 10, the wooden boards 30 can be laid so that the joints between adjacent wooden boards 30 and the fitting parts of the deck plate 40 form a lug joint. This makes it possible to address gaps between the deck plate 40 and the wooden boards 30, improving the fire resistance, structural performance, and livability of the roof or floor.

[0046] Typically, when installing or renovating the insulation material 50 and waterproofing material 60, chips are generated from the deck plate 40 during the process of fastening the insulation material 50 and waterproofing material 60 to the deck plate 40 using bolts or the like that penetrate the insulation material 50 and waterproofing material 60. In each of the above-described embodiments, because the wooden boards 30 are installed below the deck plate 40, the chips generated can be caught on the upper surface of the wooden boards 30. This eliminates the need for protective work such as laying a sheet on the underside of the deck plate 40, which shortens the construction period. Furthermore, construction can be carried out without halting operations on the floors below.

[0047] Furthermore, by drilling pilot holes at predetermined intervals in the deck plate 40, it is possible to easily join the deck plate 40 to the beam 10, the deck plate 40 to the wooden board 30, and the deck plates to each other. [Explanation of symbols]
