Description

Application of Article 30, Paragraph 2 of the Patent Act On June 3, 2020, Tsutomu Kitazaki, the representative director of TMS Co., Ltd., sent a message to Yoshihito Taguchi, an employee of TMS Co., Ltd., about the “flooring support device” invented by Tsutomu Kitazaki. At the office on the second floor of the head office building of Doshin Kenzai Co., Ltd., we sent an email to Ishimoto Architects Co., Ltd. to propose a product related to ``and a floating floor structure using the same.'' Furthermore, on July 28, 2020, we explained the contents of the product to Toyo Kogei Co., Ltd. at the office on the second floor of Doshin Kenzai Co., Ltd.'s head office building. In addition, on December 23, 2020, at the office of Daikyo Co., Ltd., the same product ( Mainly, the outline of the point that a slope is formed on the horizontal piece of the flooring support has been explained.

The present invention relates to a flooring support and a floating floor structure using the same, and particularly to a flooring support suitable for use in flooring materials such as tiles, stones such as natural stone, concrete panels, and synthetic resin panels such as acrylic. and related to floating floor structures using the same.

An example of the prior art that forms the background of the present invention includes a method in which a joist is installed on a support leg member such as a floor bundle placed on a slab surface on the roof of a building, and a plurality of floor joists are installed in a direction perpendicular to the joist. It is generally known that materials are arranged at intervals. When the weight of the flooring material is relatively large, the multiple flooring materials are simply placed on top of the joists, but when the weight of the flooring material is relatively light, the multiple flooring materials are placed on top of the joists. It is known to be placed on top of a joist by being fixed with adhesive, for example.
On the other hand, as buildings become taller in recent years, so-called building winds are occurring, and these building winds have a negative impact on buildings. In addition, in recent years, super typhoons brought about by abnormal weather caused by the effects of global warming and other factors have had an immeasurable impact on buildings. When the above-mentioned floating floor is constructed on a building, there is an increased risk that "wind blow-up" will occur due to building winds or strong winds from a typhoon, and the flooring material of the floating floor will be scattered and fall from the building. In other words, it is expected that objects falling from building rooftops will become a serious social problem.
In this case, it has been proposed to increase the weight of each flooring material to increase its strength against "wind blowing up" and prevent the flooring materials from scattering (for example, see Patent Document 1). ).

Patent No. 5143947

However, increasing the weight of each flooring material increases the weight load applied to the entire roof slab surface, which increases the construction cost because it is necessary to increase the strength of the building frame itself, such as beams and columns. .
On the other hand, in conventional floating floors, where each flooring material is firmly fixed on the joists with adhesive, when renovating an aging floating flooring material, the old flooring material is removed and then the new flooring material is installed. However, since the flooring is firmly fixed to the joists, for example, if the flooring is partially damaged, it will be difficult to replace only the damaged part and renovate. There was a problem in that the entire old flooring material had to be discarded and the entire flooring material had to be renovated, and the discarded flooring material became industrial waste and placed a large burden on the environment.
In recent years, reducing construction waste as much as possible has become even more important from the standpoint of environmental conservation and resource conservation.
That is, when each flooring material is firmly fixed to the joists with an adhesive, it is difficult to partially replace the flooring material, and it is also difficult to reduce the load on the environment.

Therefore, the main purpose of the present invention is to strengthen the connection strength with the flooring material, to prevent the phenomenon of the flooring material being blown up by the wind, and to make it possible to replace the flooring material and to be environmentally friendly.

The floating floor structure 100 according to this embodiment includes a plurality of joists 30 arranged substantially parallel to each other at intervals above a concrete slab 50 provided outdoors. A plurality of flooring materials 32 are arranged on the upper surfaces of the plurality of joists 30 at intervals and in a direction substantially orthogonal to each joist 30 in a plan view. In this case, the flooring material 32 is arranged on the upper surface of the joist 30 so that the width direction or the longitudinal direction of the flooring material 32 is perpendicular to the longitudinal direction of the joist 30 when viewed in a plane. The plurality of flooring materials 32 are each positioned at a predetermined position on the upper surface of each joist 30 by the plurality of flooring material supports 10, and each joist 30 and the flooring material 32 are connected. In this floating floor structure 100, as shown in FIGS. 1 and 2, for example, the flooring supports 10 are used to provide space between two sides of the flooring 32 that are spaced apart and parallel to each other in plan view on the upper surface of each joist 30. , an elongated gap 34 (G) is provided along the longitudinal direction of the joist 30.
Note that, as the floor material 32, in particular, for example, tile panels, stone panels made of natural stones such as marble and granite, concrete panels, synthetic resin panels such as acrylic resin, etc. can be used.

Therefore, this floor material support 10 will be described in detail below, with particular reference to FIG. 4, for example.
As shown in FIGS. 4A and 4B, the flooring support 10 is made of a metal material such as aluminum, and has a horizontal piece 12 and a vertical piece 14 in an L-shape in cross section. It is formed. As shown in FIG. 1, the horizontal piece 12 has a longitudinal direction extending along the width direction of the joist 30, and has a length L1, a width L2, and a thickness as shown in FIGS. 4(A) and (B). It has a height h1. As shown in FIG. 2, this horizontal piece 12 is arranged so that one main surface (lower surface) faces the upper surface side of the joists 30, and the other main surface (upper surface) faces the lower surface side of the flooring material 32. It is arranged as follows.

Further, as shown in FIGS. 4A and 4B, this horizontal piece portion 12 is provided with a biting portion 12a formed of a large number of uneven portions on the other main surface (upper surface). As shown in FIG. 2, the biting portion 12a bites into the lower surface of the flooring 32 under the load of the flooring 32 when the joists 30 and the flooring 32 are connected by a connecting member 18, which will be described later.

The vertical piece 14 is vertically erected from one end of the horizontal piece 12 in the longitudinal direction. As shown in FIGS. 1 and 2, this vertical piece 14 is provided to extend upward between two flooring materials 32 arranged adjacent to the upper surface of the joists 30, and It is possible to form a gap G between the materials 32, which will serve as a drainage section 34. In this case, the vertical piece 14 is provided extending in the longitudinal direction of the joist 30, as shown in FIG. 1, and has a length L2, a width W, and a height ( Thickness) H. Note that the height (thickness) H of the vertical piece 14 is determined by the thickness (height) h1 of the horizontal piece 12 and the inner surface 14a of the vertical piece 14, as shown in FIG. 4(B). The thickness (height) h2 of .

Furthermore, as shown in FIGS. 4(A) and 4(B), the flooring support 10 has a through hole in the longitudinally intermediate portion of the vertical piece 14, preferably in the longitudinally central portion of the vertical piece 14. It has 16. This through hole 16 penetrates the vertical piece 14 in the height direction (H). Furthermore, a female threaded surface 16a is formed on the inner peripheral surface of the through hole 16.
Furthermore, as shown in FIG. 2, the flooring support 10 includes a connecting means 18 that is screwed into a threaded surface (female threaded surface) 16a of the through hole 16 to removably connect the flooring 32 and the joist 30. are doing. As shown in FIGS. 2 and 6, the connecting means 18 has a threaded surface (male threaded surface) 18a that is screwed into the threaded surface 16a of the through hole 16. For example, drill screws are suitable because they have a high resistance to loosening even after long-term use.

Further, in the floor material support 10, as shown in FIGS. 2 and 5, a first buffer member 22 as a buffer member is provided on one main surface (lower surface) of the horizontal piece 12. The first buffer member 22 is made of a synthetic resin material such as PP (polypropylene) or isobutyene-isoprene rubber (IIR) [so-called butyl rubber], and has a soundproofing effect.
In this case, the first buffer member 22 particularly has a notch 22a, as shown in FIG. This notch 22a is provided in the horizontal piece 12 facing the through hole 16 of the vertical piece 14 and a portion surrounding the periphery of the through hole 16. In addition, the first buffer member 22 is formed by, for example, applying an adhesive to the lower surface of the horizontal piece 12, pasting double-sided tape, etc., in other words, as shown in FIG. It is adhered to the lower surface of the horizontal piece 12 of the flooring support 10 by.

This notch 22a has a role of releasing chips of the first buffer member 22 and the joist 30 caused by cutting of the drill screw, for example, when the joist 30 and the flooring material 32 are connected by the connecting means 18 such as a drill screw. It has become something that we have. If the notch 22a is not provided, the area around the drill screw screwed into the first buffer member 22 may bulge due to chips from the buffer member 22 and the joist 30. If the floor material 32 is firmly connected (fastened), this notch 22a does not need to be provided.

In this flooring support 10, when connecting the joists 30 and the flooring 32 with the flooring support 10, the adhesive layer 20 is formed on the other main surface (upper surface) of the horizontal piece 12, and the horizontal piece The other main surface (upper surface) of the portion 12 and the lower surface of the flooring material 32 can be bonded to each other. In this case, an adhesive layer 20 is formed on the upper surface of the biting part 12a of the horizontal piece part 12 by applying an adhesive, for example, and the adhesive layer 20 forms the other main part of the horizontal piece part 12 of the flooring support 10. The surface (upper surface) is adhered to the lower surface of the flooring material 32.

In the floating floor structure 100 according to the present embodiment, the plurality of flooring materials 32 are positioned at predetermined positions on the upper surface of the plurality of joists 30 by the above-mentioned flooring material support 10, and each joist 30 and each flooring material 32 are connected to each other. are firmly connected.
In the floating floor structure 100 according to the present embodiment, as shown in FIG. A plurality of flooring supports 10 are installed at intervals in gaps 34 (G) extending in the longitudinal direction of each joist 30. In this embodiment, one floor material 32 is supported by, for example, four floor material supports 10, as shown in FIG. In this case, one floor material support 10 is arranged near each of the four corners of one floor material 32, and one floor material 32 is constructed between two joists 30 by these four floor material supports 10. There is.
The flooring support 10 has the other main surface (upper surface) of its horizontal piece 12 in contact with the lower surface of each flooring 32, and the side surface of its vertical piece 14 on the side of each flooring 32. It is arranged like this. In this case, as shown in FIGS. 2 and 6, in the flooring support 10, the side surface of the flooring 32 is brought into close contact with the inner surface 14a of the vertical piece 14 of the flooring support 10, and the horizontal piece The biting portion 12a on the upper surface of the portion 12 is brought into close contact with the lower surface of the flooring 32. Then, the adhesive layer 20 formed on the other main surface (upper surface) of the horizontal piece 12 of the floor material support 10 is attached so as to be adhered to the side surface of the floor material 32.

In addition, in the floating floor structure 100 according to the present embodiment, as shown in FIGS. 1 and 3, on the upper surface of the joist 30, there is a gap between two flooring materials 32 arranged in parallel with an interval in the width direction of the joist 30. A second buffer member 26 as a buffer member is disposed at an intermediate portion in the longitudinal direction, preferably at a central portion. The second buffer member 26 is formed to have a longer length in the longitudinal direction than the first buffer member 22, and its width in the width direction is approximately the same as the length in the width direction of the first buffer member 22. is formed.
As shown in FIGS. 1 and 2, this second buffer member 26 is attached so as to straddle the lower surface between two adjacent flooring materials 32. In this case, an adhesive layer 28 is formed by, for example, applying an adhesive to the lower surface of the second buffer member 26, and the second buffer member 26 is attached by being adhered to the upper surface of the joist 30 using the adhesive layer 28. This second buffer member 26 has a soundproofing effect like the first buffer member 22, but also has the function of absorbing the deflection of the two adjacent flooring materials 32. It becomes.
Note that a plurality of second buffer members 26 are appropriately arranged between the other joists 36 and the flooring material 32 at intervals in the longitudinal direction of the other joists 36.

Furthermore, in the floating floor structure 100 according to this embodiment, as shown in FIGS. 7, 8, and 9, the upper surface of the concrete slab is The floating floor structure 100 can be supported at predetermined intervals in the height direction. These support means 40, support means 42, and support means 44 are erected on the upper surface of a concrete slab provided outdoors, for example, by appropriate fixing means (not shown).

In the above-described embodiment, the flooring support 10 is made of a metal material such as aluminum, but the material is not limited thereto, and may be modified as appropriate depending on the material of the flooring 32. For example, when the floor material 32 is a tile panel, a concrete panel, or a stone panel, the floor material support 10 is preferably made of a metal material such as aluminum; however, when the floor material 32 is a synthetic resin panel such as acrylic resin, the floor material The support 10 is preferably made of synthetic resin material.
In addition, in the above-described embodiment, as shown in FIG. , for example, at two locations at intervals in the gaps 34 (G) extending in the longitudinal direction of each joist 30; Although a total of four flooring supports 10 were installed in the vicinity, the number of installed flooring supports 10 is not limited thereto, and for example, three flooring supports 10 are installed at intervals in the longitudinal direction of the gap G. The floor material support 10 may be provided at at least two locations.

According to the floating floor structure 100 in which the floor material support 10 according to the present embodiment described above is used, in particular, as shown in FIG. 32, the inner surface 14a of the vertical piece 14 becomes a contact surface for positioning each flooring material 32, and the flooring material 32 is accurately positioned on the upper surface of each joist 30. can do. Moreover, between the plurality of flooring materials 32 positioned by this flooring material supporter 10, the length W in the width direction of the vertical piece part 14 of the flooring material supporter 10 shown in FIG. As shown in FIG. 2, a drainage section 34 having a function of draining rainwater and the like is disposed through a gap G provided between each flooring material 32.

Furthermore, in this floating floor structure 100, the joists 30 and the flooring 32 are removably connected by the connecting means 18, so the flooring 32 can be easily removed. Therefore, even if any floor material 32 of the floating floor structure 100 has a problem due to deterioration, damage, etc., it is possible to replace the deteriorated or damaged floor material 32 as appropriate.
On the other hand, in the conventional technology, when each flooring material is firmly fixed to the joist with adhesive, when renovating an aging floating floor material, the old flooring material is removed and then the new flooring material is laid. However, because the flooring is firmly fixed to the joists, for example, if the flooring is partially damaged, it is difficult to replace only the damaged part and renovate, and in some cases, the old flooring may be damaged. There was a problem in that the entire flooring had to be discarded and refurbished, and the discarded flooring became industrial waste and placed a large burden on the environment.
On the other hand, in this floating floor structure 100, as described above, the flooring material 32 can be easily replaced, so it is possible to reduce the amount of various flooring materials that become industrial waste. Therefore, in recent years, it has become possible to meet the demands of society, where reducing construction waste as much as possible has become even more important in terms of environmental conservation and resource conservation.

Further, according to the floating floor structure 100 according to the present embodiment, by using the floor material support 10, the joists 30 and the floor material 32 are firmly connected by the synergistic effect of the connecting means 18 and the adhesive layer 20. Therefore, there is no need to increase the weight of each flooring material 32, unlike the prior art shown in Patent Document 1 and the like. Therefore, it is possible to prevent the weight load from increasing on the entire roof slab surface, and by extension, it is not necessary to increase the strength of the building frame itself such as beams and columns, which can lead to high construction costs. do not have.

That is, according to the floating floor structure 100 in which the floor material support 10 according to the present embodiment is used, the connection strength with the floor material 32 is strengthened, and the blowing up phenomenon of the floor material 32 where the entire floor material is rolled up by the wind is prevented. To provide a floor material support 10 and a floating floor structure 100 using the same, which can prevent the above-mentioned problems, easily replace the floor material 32, and reduce environmental loads from the viewpoints of environmental conservation and resource saving. be able to.

FIG. 12(B) is a front view of FIG. 12(A). 13 is an enlarged view of the main part shown in FIG. 12, FIG. 13(A) is an enlarged plan view of the main part of FIG. 12(A), and FIG. 13(B) is an enlarged plan view of the main part of FIG. 12(B). It is an enlarged front view.
In the floating floor structure 110 according to this embodiment, compared to the floating floor structure 100 shown in FIGS. 1 to 3, as shown in FIGS. 12 to 14, in particular, as shown in FIG. , A plurality of flooring materials 32 are positioned at predetermined positions on the upper surface of the plurality of joists 30 by the flooring material supports 10A and 10B shown in FIG. 11, and each joist 30 and each flooring material 32 are firmly connected. Ru.
In the example of the floating floor structure 110 shown in FIGS. 12 to 15, the upper surface of the horizontal piece 12 of the pair of floor material supports 10A, 10B has a slope of (b-c)/a, so the floor material Each of the flooring materials 32 supported by the supports 10A and 10B has a slope of (b-c)/a on the upper surface of each of the flooring materials 32, as shown in FIG. 13(B). There is.

Therefore, in the floating floor structure 110 according to this embodiment, as shown in FIGS. , and can be arranged so as to be inclined, for example, in a ``V'' shape or an inverted ``V'' shape, with the drainage portion 34 (gap G) in between. That is, the upper surfaces of the two flooring materials 32 are arranged in a direction (b-c )/a and are arranged in a ``V'' shape that slopes diagonally downward.
Further, when viewed in FIG. 13(B), the upper surfaces of the two flooring materials 32 are (b-c)/towards the left and right of the drainage part 34 (gap G) located on the right side, for example They are arranged in an inverted ``V'' shape that slopes diagonally upward at a slope of a.

Therefore, in the floating floor structure 110 according to this embodiment, the slope of (b-c)/a is formed on the upper surface of the flooring 32 supported and fixed on the upper surface of the joists 32 by the flooring supports 10A and 10B. Therefore, especially as shown in FIG. 14, water such as rainwater flows into the drainage portion 34 (gap G) along the slope surface of each flooring material 32 and is drained downward. Therefore, in the floating floor structure 110, it is possible to prevent water from accumulating on the upper surface of the flooring material 32.
This phenomenon of water puddles is, for example, what is called "oya water" (common name), and since conventional floating floor structures do not have the above-mentioned drainage structure, the water pooling occurs in the center of the upper surface of the floor material or The water was generated anywhere on the top surface. Therefore, with conventional floating floor structures, when people pass on the top surface of the flooring, there are problems such as getting caught in a puddle and falling, or water getting into footwear such as shoes and getting wet socks. It was something. Additionally, there have been complaints that the water in the puddles causes the upper surface of the flooring material to become a pseudo-mirrored surface, with women's underwear being reflected on the surface of the water through their skirts, for example. In such cases, it is particularly unsuitable for floating floor structures installed in commercial facilities and the like. Furthermore, when the wheelchair passes over the top surface of the flooring material, the tires of the wheels of the wheelchair get wet with water, so there is a risk that the hands operating the wheelchair may become wet with water, which may impede the operation of the wheelchair.
On the other hand, in the floating floor structure 110 shown in FIGS. 12 to 14, etc., the flooring materials 32 adjacent to each other with a gap 34 (G) in the width direction of the joists 30, for example, have a drainage structure shown in FIG. This feature makes it possible to prevent the occurrence of "water" and eliminate the various defects, complaints, and problems of the conventional floating floor structure described above. In addition, this floating floor structure 110 has the above-mentioned drainage structure, and since the entire upper surface of the floor material of the floating floor structure can take a level of +-0 (plus or minus zero), it is easy to use in a wheelchair. It has no hindrance to driving and is suitable for so-called barrier-free use.

Furthermore, in this floating floor structure 110, for example, two through holes 16 are provided at intervals in the longitudinal direction of the vertical piece 14, compared to the flooring support 10 shown in FIGS. 4(A) and 4(B). It is arranged. Each of the two through holes 16 has a threaded surface (female threaded surface) 16a formed on its inner peripheral surface (see FIGS. 10 and 11). The pair of flooring supports 10A and 10B are each screwed into threaded surfaces (female threaded surfaces) 16a of the two through holes 16, and the joists 30 and the flooring 32 are connected by connecting means 18 such as two drill screws. Detachably connected. Therefore, even if any floor material 32 of the floating floor structure 100 has a problem due to deterioration, damage, etc., it is possible to easily replace the deteriorated or damaged floor material 32 as appropriate.

In this floating floor structure 110, the flooring supports 10A and 10B each have two through holes 16 provided with threaded surfaces (female threaded surfaces) 16a, so the flooring 32 can be reused. Even if the through holes 16 are misaligned when attached to the joist 30 using the supports 10A and 10B, it is possible to use one of the two through holes 16 as a waste hole and use the other through hole 16. can.
Furthermore, in this floating floor structure 110, compared to the floating floor structure 100 shown in FIGS. Since the two connecting means 18 are provided, the joists 30 and the flooring 32 can be connected even more firmly. In this case, since the connection strength between the joists 30 and the flooring material 32 is increased by the two connecting means 18, the floating floor structure 110 can further strengthen the phenomenon that the flooring material 32 is blown up when the entire flooring material is blown up by the wind. It can be prevented.
Furthermore, since this floating floor structure 110 is provided with two connecting means 18, even if one of the connecting means 18 (such as a drill screw) becomes loose due to aging deterioration or the like and lifts up, the other connecting means 18 It can be reinforced by means 18.
