Hereinafter, embodiments of the seismic bed of the present invention will be described in detail with reference to FIGS. 1 to 5.

As shown in FIGS. 1A and 1B, the seismic bed 1 is installed in the room 100 located on the first floor of the house. The bed body 60 is supported by the ground 110 via the holding portion 10. The upper part of the bed body 60 is covered with the top plate portion 40. The top plate portion 40 is supported by the holding portion 10. The holding portion 10 has a top plate holding material 12 for holding the top plate portion 40 and a foundation connecting material 11 for connecting to the foundation structure 50, and the top plate holding material 12 and the foundation connecting material 11 can be attached and detached. You are connected.

The bed body 60 is supported by a support frame 18 mounted on the top plate holding material 12. The support frame 18 is detachably connected to the top plate holding material 12 in a state of being assembled in all directions at the lower end portion of the frame material 13. As a result, the strength of the frame material 13 is increased and deformation is suppressed.

The top plate portion 40 is for receiving the falling object from the ceiling and preventing the falling object from falling onto the bed body 60, and is held by the horizontal connecting member 14 in a detachable state. The material of the top plate portion 40 is preferably a plate-like structure that is lightweight, rich in flexibility, and excellent in strength. For example, a polycarbonate plate is preferable. Further, the structure is not limited to the plate-like structure, and may be a film-like structure woven with aramid fibers or the like.

Four foundation holes 50a are defined in the ground 110 directly below the four corners of the bed body 60, and the foundation structure 50 is constructed by penetrating the foundation connecting material 11 into the foundation concrete 51 filled in each foundation hole 50a. is doing. Further, each of the four foundation connecting materials 11 penetrates into the respective foundation concrete 51 via the floor hole 30a defined in the floor 30. The floor holes 30a are located directly below the four corners of the bed body 60. In the present embodiment, the floor 30 is illustrated as a wooden floor, but it may be a tatami mat floor. Further, although the foundation connecting material 11 exemplifies a circular tube made of metal, it may be a square tube.

The foundation structure 50 has a structure in which the foundation connecting material 11 penetrates into the foundation concrete 51, but the foundation connecting material 11 may penetrate directly into the ground 110, or the foundation connecting material may be formed after shaping the unevenness of the ground 110. 11 may be placed directly. The foundation structure 50 may be appropriately determined in consideration of the condition of the ground 110, the assumed impact force of the falling object falling on the top plate portion 40, and the like.

A filling member 20 is installed in the floor hole 30a, and the foundation connecting material 11 penetrates the central portion of the filling member 20. As shown in FIG. 2A, the filling member 20 has a collar portion 21 at the upper end portion, and the filling material 23 is arranged inside the outer cylinder 22. The collar portion 21 is a donut-shaped flat plate having an outer edge larger than the outer diameter of the floor hole 30a in a plan view, and is fixed to the floor 30.

The outer cylinder 22 is a cylinder extending downward (in the direction of the ground 110) from the inner edge of the flange portion 21 and is inserted into the floor hole 30a. The filler 23 is a thick cylinder and is filled in the gap formed between the outer cylinder 22 and the foundation connecting material 11. As a result, the floor hole 30a can be closed. By making the material of the filler 23 highly flexible and having excellent anti-vibration performance, it is possible to suppress the shaking of the bed body 60 when an earthquake occurs. In this embodiment, urethane foam and anti-vibration rubber are exemplified. Not limited to this, a laminated structure having at least two layers may be used. For example, as shown in FIG. 2B, the upper layer filler 223a may be urethane foam, the lower filler 223b may be vibration-proof rubber, the upper filler 223a may be vibration-proof rubber, and the lower filler 223b may be urethane foam. It may be a filling member 220. The wall thickness of the filler 23 may be appropriately determined in consideration of the assumed seismic intensity of the earthquake, the rigidity of the foundation connecting material 11, the weight of the bed body 60, and the like so that sufficient vibration isolation can be obtained.

As shown in FIG. 3, the top plate holding material 12 has a pair of frame materials 13 and 13 which are arch-shaped square cylinders. The pair of frame members 13 and 13 are connected to each other via the horizontal connecting member 14. It is preferable that the frame member 13 and the horizontal connecting member 14 are separably connected. As a result, the top plate holding material 12 can be easily carried into the room 100.

The procedure for installing the seismic bed 1 in the present embodiment will be described with reference to FIG.

Select a place where the seismic bed 1 is planned to be installed at any position of the room 100 on the first floor of the house. The house may be a one-story house or a two-story building, but the seismic bed 1 cannot be installed on the second floor, and must be a predetermined place in the room 100 on the first floor.

The floor 30 is cut with a cutter or the like to define the four floor holes 30a. The position of the floor hole 30a is a predetermined position in the vicinity immediately below the four corners of the seismic bed 1. A double scoop is inserted through the floor hole 30a to excavate the ground 110. The excavated earth and sand are carried into the room 100 via the floor hole 30a and then carried out to the outside. The size of the floor hole 30a may be appropriately determined in consideration of the work efficiency of the excavation work.

When the ground condition is relatively soft, excavate with a double scoop around 1 m to define the foundation hole 50a. Further, when the excavation depth is less than 1 m and the ground condition becomes hard and the excavation becomes difficult, the excavation of the ground 110 may be stopped.

The foundation connecting material 11 is built in the foundation hole 50a. When building, it is preferable to secure the verticality of the foundation connecting material 11 by using the building jig 52. Specifically, the building jig 52 is installed on the floor 30, and the foundation connecting material 11 is inserted into the floor hole 30a via the hole 52a defined in the building jig 52 to secure the verticality. In this state, the bottom of the foundation connecting material 11 is further lowered to connect to the ground 110.

Concrete is poured from the floor hole 30a into the foundation hole 50a to construct the foundation concrete 51. After confirming that the concrete has solidified and the predetermined strength is secured, the building jig 52 is removed so that only the foundation connecting material 11 is supported by the foundation concrete 51. It is preferable that the concrete to be cast is one that solidifies quickly and can develop a predetermined strength at an early stage. As a result, the installation period of the seismic bed 1 can be shortened.

After inserting the filling member 20 from the upper end portion of the foundation connecting material 11 and installing it on the floor 30, the flange portion 21 is fixed to the floor. As a result, the gap formed between the floor hole 30a and the foundation connecting material 11 is closed, the movement of air between the room 100 and the floor can be restricted, and a good environment in the room 100 can be maintained. Further, the foundation connecting material 11 is in a state of being joined at two points of the foundation concrete 51 and the filling member 20, and has a structure capable of restraining the displacement of the upper end of the foundation connecting material 11.

After inserting the insertion pipe 15 attached to the frame material 13 into the upper end of the foundation connection material 11, the foundation connection material 11 and the insertion pipe 15 are connected using bolts.

After connecting the pair of frame members 13 and 13 and the foundation connecting member 11, the horizontal connecting member 14 is bridged between the pair of frame members 13 and 13. The top plate portion 40 is placed on the horizontal connecting member 14, and the top plate portion 40 is connected to the horizontal connecting member 14.

After assembling the support frame 18 in all directions, the bed body 60 is placed on the support frame 18. As a result, the bed body 60 is directly supported by the ground 110 via the holding portion 10.

This embodiment is an example, and it is needless to say that the present embodiment can be modified without departing from the technical idea of the present invention. For example, in the present embodiment, four floor holes 30a are defined and one foundation connecting material is inserted into each of the four floor holes 30a, but two or more floor holes 30a are inserted. The number of floor holes 30a may be set to 2 or 3 by inserting the foundation connecting material 11.

The seismic bed according to the present invention can avoid the risk of being shaken off the bed and falling to the floor surface even if an earthquake suddenly occurs while lying down. Especially for those who are forced to lie down in bed, it has great industrial applicability because it can ensure safety in the event of an earthquake.
