Description

  The present invention relates to a structure of a vibration-damping floor in which a horizontal force applied in the event of an earthquake is borne by a plurality of structural floor panels constituting a floor in a building having a rigid frame structure.

  2. Description of the Related Art Conventionally, in a building having a frame structure of a ramen structure, a floor is configured by attaching a plurality of floor panels between opposing beams as disclosed in, for example, Patent Document 1. A horizontal brace is bridged between the beams at a position below the floor panel. When a horizontal force such as an earthquake is applied, the floor portion composed of a plurality of floor panels is not burdened with the horizontal force. The horizontal force is borne by a horizontal brace that is bridged below the floor panel.

  However, in the above conventional example, since the horizontal brace is disposed at the lower position of the floor panel, there is not only a problem that the horizontal brace is required, but also the construction is required because the horizontal brace needs to be constructed. In addition, the pocket of the ceiling space (that is, the vertical length of the ceiling space) becomes longer (higher), which increases the height of the building and increases the cost. Since there are horizontal braces inside, piping and wiring are passed through the ceiling space, or when placing lighting equipment, air conditioners, etc., the horizontal braces can interfere with piping and wiring. Lighting fixtures, air conditioners, etc. cannot be placed, or the placement positions of piping, wiring, lighting fixtures, and air conditioning devices are restricted by horizontal braces, or placed in the ceiling space Working through a and wiring, there is a problem that distribution 設作 industry luminaire or air conditioner hardly.

  Therefore, as a solution to the above conventional example, by fixing the structural floor panel with the structural face plate attached to the upper surface of the outer peripheral frame to the beam, the structural floor panel bears the horizontal force acting during an earthquake. This is proposed in Patent Document 2.

However, in a structure in which a structural floor panel as shown in Patent Document 2 is fixed to a beam and the horizontal force in the event of an earthquake is borne by the structural floor panel, the structural floor panel is deformed in the event of an earthquake. Then, there is a problem that the deformation remains as it is even when the horizontal force is released.

  The present invention has been invented in view of the above-mentioned conventional problems, and can bear a horizontal force acting during an earthquake by a structural floor panel that is a structural member of a floor formed on a frame structure of a ramen structure. In addition to providing a damping floor structure that can also exhibit a damping effect and that can be automatically restored to the original state when the horizontal force is released even if the structural floor panels are displaced due to the action of the horizontal force. Is an issue.

  In order to solve the above-mentioned problem, the structure of the vibration-damping floor according to the present invention includes a plurality of structural floor panels 3 for bearing a horizontal force acting during an earthquake between the beams 2 constituting the frame body 1 of the rigid frame structure. Each structural floor panel 3 is disposed and fixed to the beam 1 to form a floor 4, and the side surfaces of adjacent structural floor panels 3 are connected to each other through elastic restoring rubber 5. It is characterized by this.

  By adopting such a configuration, when a horizontal force such as an earthquake is applied to the frame structure 1 of the ramen structure, the horizontal force can be borne by a plurality of structural floor panels 3 fixed to the beam 2. There is no need to hang a horizontal brace under the floor 4 for bearing a horizontal force as in the prior art, and it is controlled by an elastic restoring rubber 5 that connects the side surfaces of adjacent structural floor panels 3. In addition to exerting a vibration effect, even if the adjacent structural floor panels 3 are displaced due to the action of horizontal force, the adjacent structural floor panels 3 are restored to each other by the restoring rubber 5 when the horizontal force is released. The state can be restored so that the deformation of the floor 4 does not remain as it is.

  Moreover, it is preferable that the structural floor panel 3 is configured by fixing the face plate 9 on the panel frame 8 configured by laying the diagonal member 7 in the outer peripheral frame 6.

  With such a configuration, the structural floor panel 3 that bears the horizontal force can be configured with a simple configuration in which the diagonal member 7 is installed on the outer peripheral frame 6.

  In the present invention, when a horizontal force such as an earthquake acts, the horizontal force acting at the time of an earthquake can be borne by a plurality of structural floor panels which are constituent members of a floor formed on a frame structure of a ramen structure. The restoration rubber that connects the side surfaces of the floor panel can also exhibit a damping effect, and when the horizontal force is released even if the structural floor panels are displaced by the action of the horizontal force, the restoration rubber automatically Therefore, the original state can be restored and the floor deformation does not remain.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  A frame 1 having a ramen structure is constructed by laying a metal beam 2 between metal columns 10. A large number of floor panels are arranged between the beams 2 facing each other, and the floor 4 is configured by fixing the floor panels to the beams 2. Here, in the present invention, among the many floor panels for configuring the floor 4, a plurality of floor panels are configured by the structural floor panel 3.

  As shown in FIG. 3, the structural floor panel 3 has a metal diagonal member 7 laid in a square shape in plan view in an outer peripheral frame 6 in which a metal frame material having a U-shaped cross section is framed in a rectangular shape in plan view. Thus, the panel frame 8 is configured, and the face plate 9 is fixed to the panel frame 8. Since this structural floor panel 3 is constructed by laying a metal diagonal member 7 in a metal outer peripheral frame 6, a horizontal force acting in the event of an earthquake is applied by the diagonal member 7 installed in the outer peripheral frame 6. You can pay.

  In the embodiment of FIG. 2, the face plate 9 is configured by attaching the plate material 9b to the upper surface of the wooden frame 9a and filling the portion surrounded by the wooden frame 9a with the heat insulating material 9c, but only the plate material 9b. The face plate 9 may be configured. Further, when a structural face plate is used as the face plate 9, the load of horizontal force during an earthquake can be further increased. In the embodiment shown in FIG. 3, an example in which the intermediate frame 11 is installed on the outer peripheral frame 6 having a rectangular shape is shown.

  As shown in FIG. 1, at least two structural floor panels 3 are arranged adjacent to each other between the opposing beams 2 of the frame structure 1 of the ramen structure, and the structural floor panels 3 are arranged on the opposing beams 2 respectively. It is fixed by fixing means such as bolt connection. Here, the structural floor panel 3 may be directly fixed to the beams 2 facing each other with bolts or the like, or a fixing bracket may be fixed to the beam 2 and the structural floor panel 3 may be fixed to the fixing bracket. .

  Adjacent structural floor panels 3 are connected to each other through a restoring rubber 5 having elasticity. As shown in FIG. 4, the restoration rubber 5 has connecting plates 12 integrally fixed on both sides thereof, and bolts 13 project outward from the connecting plates 12 on both sides of the restoration rubber 5, respectively. Bolts 13 on both sides are fixed to side surfaces of the adjacent structural floor panel 3 using nuts 14 as shown in FIG.

  As described above, a plurality of structural floor panels 3 are installed between the beams 2 constituting the frame structure 1 of the ramen structure, and the side surfaces of the adjacent structural floor panels 3 are elastically connected via a restoring rubber 5 having elasticity. Because they are connected, when a horizontal force such as an earthquake acts on the frame 1 of the ramen structure, it is transmitted from the beam 2 to the structural floor panel 3, and the structural floor panel 3 bears the horizontal force such as an earthquake. Furthermore, vibration is suppressed by a restoring rubber 5 that connects the structural floor panels 3 together. Thus, since the structural floor panel 3 constituting the floor 4 can bear a horizontal force such as an earthquake, it is not necessary to provide a horizontal brace below the floor 4 in order to bear the horizontal force as in the prior art. There is no need to lay a horizontal brace over the ceiling space, so when placing various equipment such as pipes, wiring, lighting equipment and air conditioners in the ceiling space, it can be freely positioned without being restricted by the horizontal brace. It can also be arranged, and the pocket (vertical height) of the space behind the ceiling can be shortened. In this case, the height of the building can be lowered and the cost can be reduced.

  Moreover, even when the structural floor panels 3 are displaced due to the horizontal force such as an earthquake, when the horizontal force is released, the restoring force of the restoring rubber 5 automatically restores the original state. For this reason, even if a horizontal force such as an earthquake acts and temporarily deforms, the floor 4 returns to its original state as soon as the horizontal force is released. Therefore, deformation of the floor 4 is prevented.
