(技術分野)
本考案は防震効果の大きい建物の階上床に関す
る。[Detailed description of the invention] (Technical field) The present invention relates to an upper floor of a building that has a large earthquake-proofing effect.
(従来技術及び問題点)
建物の階上床は通常梁間に架設した根太の上面
に床面材を張設して構成される。根太は床スパン
の短辺方向に架設される為、短辺方向に比べ長辺
方向の剛性が低くなり、この両者の不均衡が階上
床の耐震性能を十分発揮させないでいる。そのた
め従前から根太下面に根太と直行した状態で防震
材を配設した、所謂防震床構造(実公昭60−
28736号)が提案されている。(Prior Art and Problems) The upper floor of a building is usually constructed by placing flooring material on top of joists installed between beams. Because the joists are installed in the short side direction of the floor span, the rigidity in the long side direction is lower than that in the short side direction, and the imbalance between the two prevents the upper floors from fully demonstrating their seismic performance. For this reason, the so-called seismic floor structure (1986-
28736) is proposed.
しかし、これらの防震床構造は根太の有効断面
を大きくしたり、面材の厚さを厚くしたりするも
のであり、コストの面から良策とはいえない。又
防震材を根太の下面に取付けたりするが、階上床
下面に天井材を張設する際に防震材自体が取付施
工の邪魔になる等、コスト及び造作施工において
問題を生じている。 However, these earthquake-proof floor structures require increasing the effective cross section of the joists or increasing the thickness of the facing material, which is not a good idea from a cost standpoint. Furthermore, seismic insulation materials are attached to the underside of the floor joists, but this poses problems in terms of cost and construction work, such as the seismic insulation material itself getting in the way of installation work when ceiling materials are installed on the underside of floors above and below floors.
(問題点を解決するための手段)
本考案は上記問題点を解決するため、隣接する
根太間に根太と直行する状態に補剛板を介装した
ことを特徴とするもので、床全面に防震効果が有
効に発揮される。(Means for solving the problem) In order to solve the above problem, the present invention is characterized by interposing a stiffening plate between adjacent joists in a state that is perpendicular to the joists. Earthquake prevention effects are effectively demonstrated.
又根太下面より補剛板を突出させないので天井
内部の造作も容易に施工できるものである。 Also, since the stiffening plate does not protrude from the lower surface of the joist, it is possible to easily construct the interior of the ceiling.
(実施例)
以下図面により本考案の防震階上床を詳細に説
明する。(Example) The earthquake-proof upper floor of the present invention will be explained in detail below with reference to the drawings.

上面に畳、カーペツト等が敷設される。 FIG. 1 is a schematic side view illustrating the upper floor 1. FIG. The upper floor 1 has joists 2, 2 in the direction of the short side between the walls of the building.
... are constructed at predetermined intervals, and a floor material 3 is stretched over the top surface. Normally joists 2, 2... are approximately 90cm
They are arranged at intervals and are constructed approximately perpendicular to the long side direction of the floor span. The floor material 3 is made of plywood, particle board, etc. of a regular length, and tatami mats, carpets, etc. are usually laid on top of it.

なる。 Figure 2 shows the stiffening plate 4 interposed between the joists 2, 2...
4 is a partially omitted perspective view for explaining in more detail. In other words, the stiffening plates 4, 4... interposed between the joists 2, 2... are brought into close contact with both end surfaces of the joists 2, 2... and the side surfaces of the joists 2, 2..., and their upper surfaces and the lower surface of the flooring material 3, so that the nails N, N It is joined by using a combination of and adhesive. Therefore, the stiffening plates 4, 4... are joined in a state in which both end faces, the side surfaces of the joists 2, 2..., and the top face and the floor material 3 are in close contact with each other, so that the three sides excluding the bottom face have an integral joint structure with the upper floor 1. becomes.

保され、期待する防震効果が得られる。 In addition, stiffening plates 4, 4, which are interposed between adjacent joists...
are installed alternately out of phase. This ensures uniform rigidity over the entire surface of the upper floor and provides the expected seismic insulation effect.
第3図は補剛板4,4…をすべての根太2,2
…間に介装させた状態の側面図である。 Figure 3 shows the stiffening plates 4, 4... for all the joists 2, 2.
... is a side view of the state in which it is interposed between the two.

ければよい。 In this case, in order to extend the ceiling material (not shown) on the underside of the upper floor 1, hangers 5, 5, etc. are directly attached to the predetermined joists 2, 2, and the lower ends of the hangers 5 are attached to the ceiling (not shown). (not shown) and attach ceiling material to the edge of the field.

果にそれほどの影響を与えない。 On the other hand, if it is not possible to attach the hanging tree 5 directly to the joists 2, 2..., install a hanging beam 6 between the walls as shown in Fig. 4, attach the hanging tree 5 to this hanging beam 6, and do the same as above. Install the veranda and ceiling material. In this case, the stiffening plate 4 cannot be interposed between the joists 2, 2.... However, since the suspension beams 6, 6... are installed at a much larger interval than the pitch of the joists 2, 2..., even if there are parts where the stiffening plates 4, 4... are not interposed, the seismic insulation effect of the entire upper floor 1 is not significantly affected. No impact.
尚、上記説明において、現場で根太2,2…を

ておくことができる。 In the above explanation, the case was explained in which the joists 2, 2... were erected on site and the flooring material 3 was stretched on top of the joists, but the present invention is not necessarily limited to this upper floor. It may be a so-called floor panel in which the joists 2, 2... are placed in parallel in advance and the floor material 3 is stretched over the upper surface thereof. In this case, the stiffening plates 4, 4, . . . can be interposed in advance in the floor panel manufacturing process.
(効果)
以上説明したように、本考案の防震階上床は、
短辺方向に根太が架設されていても階上床の長辺
方向の剛性を高めることによつて、階上床全体の
防震効果を高めることが出来る。(Effects) As explained above, the earthquake-proof upper floor of the present invention has
Even if the joists are installed in the short side direction, by increasing the rigidity of the upper floor in the long side direction, the seismic insulation effect of the entire upper floor can be enhanced.
しかも補剛板自体は根太と床面材が為す空間部
内に介装されるので階上床下面に突出することは
なく、天井材等造作施工も容易となる。 Moreover, since the stiffening plate itself is interposed within the space formed by the joist and floor material, it does not protrude to the lower surface of the upper floor, making it easier to construct ceiling materials and other features.
