Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a collapse prevention structure for a room of a wooden house that can secure a space where people inside the room can avoid being hit directly by a collapsed structure even if the wooden house is damaged by the earthquake. .

[0002]

[Problems to be solved by conventional techniques and devices]

 Traditionally, wooden houses have been said to be relatively strong against earthquakes, but it was found that they were extremely vulnerable to severe earthquakes with a seismic intensity of 6 or more, or severe earthquakes, as was evident in the previous Great Hanshin Earthquake. The weight of the tile roof peculiar to a wooden house and the deterioration of the skeletons such as foundations, columns, and beams made it even easier to collapse a house, resulting in a large number of dead people being the underlayment of the collapsed house. Even if the cause of the earthquake is found to be vulnerable, it is difficult to immediately rebuild the old wooden house because of the large financial burden.

Further, a wooden house is suitable for a humid Japanese climate, and has a more attractive appearance than a house made of reinforced concrete, and there is a strong demand for stand-alone houses. This invention, whether existing or newly built, can be installed in a room of a wooden house to protect human lives from the collapse of the room, and to clarify a structure for preventing the collapse of the room of the wooden house.

[Means for solving the problem]

 In the collapse prevention structure for a room of a wooden house of the present invention, a rigid three-dimensional frame (3) having a strength that is not crushed even when the weight of the roof acts is provided separately from the members constituting the wooden house (1). It is placed on the floor (11) of the room (2) of the house, and the side and top surfaces of the rigid three-dimensional frame (3) are installed close to the wall and ceiling (12) of the room (2).

[0005]

[Action and effect]

 The rigid three-dimensional frame (3) is placed on the floor (11) or the dirt floor (7) of the room (2) and is installed close to the wall surface and ceiling (12) of the room (2). Even if the roof collapses in response to an earthquake that collapses 1), the members that support the roof, such as beams and wood, are supported by the upper edge of the three-dimensional frame (3). Further, the falling pillars are also received by the rigid three-dimensional frame (3), so that they can be prevented from hitting a person directly.

The rigid three-dimensional frame (3) is located close to the ceiling (12) of the room (2), and the fall distance when the roof collapses is shortened. Therefore, the impact of falling can be mitigated, and the strength of the roof does not yield to the weight of the roof. Therefore, even if the rigid solid frame (3) is deformed when the roof is dropped, it cannot be completely crushed. Without it, a space where people can survive can be secured. The person in the rigid three-dimensional frame (3) has only to escape by himself or wait for rescue.

Even if the floor (11) may fall out due to the weight of the rigid three-dimensional frame (3), the space inside the rigid three-dimensional frame (3) is secured, so the rigid three-dimensional frame (3) is secured. It is possible to prevent fatal injuries to those who were inside. If the lower part of the rigid three-dimensional frame (3) penetrates the floor (11) of the room (2) and is installed in the dirt floor (7), the problem of the floor (11) falling off can be solved.

If a rigid three-dimensional frame (3) is installed in all the rooms in the house, disaster prevention against earthquakes is perfect, but it can be installed only in necessary rooms such as bedrooms, and it is more suitable for rebuilding the entire house. Overall, the economic burden is much smaller.

【Example】

 1 to 3 show an embodiment in which a rigid three-dimensional frame (3) is installed on the floor (11) of the room (2) on the first or second floor of the wooden house (1). The structure of the house (1) of the embodiment is based on the well-known frame construction method in which pillars, beams, etc. are used as axes and the space between them is closed by earth walls, board walls, gypsum board, etc., but is not limited to this. Of course, it is also possible to implement it in a house of a frame wall construction method (two-by-four construction method) in which a wall and floor are made up of only 2-inch x 4-inch studs and plywood. The room (2) is formed into a casing surrounded by a floor (11), a ceiling (12) and four wall surfaces, a total of six surfaces, and a door (13) and a window (14) are provided at appropriate places. .

When the rigid three-dimensional frame (3) is placed on the floor (11) and installed, it closes to the four walls of the room (2) and the inner surface of the room (12) and fills the room (2) completely. It is formed in size. The rigid three-dimensional frame (3) has a rigid frame structure, and four main rods (5) are erected at the four corners of the bottom frame (4), which is formed by connecting four rods to form a rectangular shape. The upper ends of are connected by four beam rods (6) (61).

Between the bottom frame (4) and each beam rod (6) (61), one or more reinforcing vertical rods are provided, avoiding the positions of the door (13) and the window (14) of the room (2). (51) is arranged in parallel with the main rod (5), and further, a reinforcing horizontal rod (52) is arranged in a proper place between the main rod (5) and the reinforcing vertical rod (51) and connected to the mating members respectively. Be touched.

As shown in FIG. 4, one or a plurality of reinforcing beam rods (62) are straddled over the beam rods (6) (6) parallel to the longitudinal direction at the top opening of the rigid three-dimensional frame (3). The beam rod (6) is arranged orthogonally and is connected to the beam rod (6). A plurality of beam rods (63) are arranged orthogonally to the reinforcing beam rod (62) between the reinforcing beam rod (62) and the short-side beam rod (61). It is connected to the rod (61). An iron plate or lath plate is installed on the rod (63) to protect the inside of the three-dimensional frame from falling objects when the room collapses.

The bottom frame (4), the main rod (5), the beam rod (6) (61), the reinforcing vertical rod (51), the reinforcing horizontal rod (52), the reinforcing beam rod (62) and the bar rod (63). ) Is made of steel with high rigidity such as H-shaped steel, C-shaped steel, channel material, square pipe, round pipe, etc., and the connection between each member and the mating member is bolted to the bracket (50) protruding from the mating member. , Or by welding. Further, braces (8) are provided between the main rods (5) and (5) and in other suitable places so as not to interfere with the windows (14) and doors (13). The braces (8) can be adjusted in tension by providing a turnbuckle (82) on a part of the round bar steel (81).

The rigid three-dimensional frame (3) is assembled into the existing house (1) after disassembling the respective constituent members and bringing them into the part (2). In the case of a new construction, it can be assembled in parallel with the construction of the house or in the room after the house is completed. When installing in a Japanese-style room, after removing the tatami and assembling the rigid three-dimensional frame (3) on the floorboard, the tatami is made smaller by the width dimension of the bottom frame (4) and laid on the floorboard. Alternatively, as shown in FIG. 4, the bottom frame (4) is reinforced with the reinforcing beam rod (62) and the beam rod (63) in the same manner as on the ceiling (12) side, and a plate is laid on the main frame (4). A tatami mat may be cut at a position corresponding to the rod (51) and laid on the plate.

However, the rigid three-dimensional frame (3) is placed on the floor (11) or the dirt floor (7) of the room (2) and is installed close to the wall surface and the ceiling (12) surface of the room (2). Therefore, even if the roof collapses in response to an earthquake that causes the house (1) to collapse, the members supporting the roof, such as beams and dead trees, are supported by the upper edge of the three-dimensional frame (3) and are supported. However, the falling pillars are also received by the rigid three-dimensional frame (3), which prevents them from hitting people directly.

The rigid three-dimensional frame (3) is located close to the ceiling (12) of the room (2), and the fall distance when the roof collapses is small, so the impact of the fall can be mitigated, and yet Since the roof does not yield to the weight of the roof, even if the roof falls, the rigid frame (3) will not be completely crushed even if it deforms, and a space where people can survive can be secured. The person in the rigid three-dimensional frame (3) has only to escape by himself or wait for rescue.

The floor (11) may fall out due to the weight applied to the rigid three-dimensional frame (3), but even in this case, the space in the rigid three-dimensional frame (3) is secured, so that the rigid three-dimensional frame ( 3) It is possible to prevent people inside from suffering fatal injuries. If the lower part of the rigid three-dimensional frame (3) penetrates the floor (11) of the room (2) and is installed in the dirt floor (7), the problem of the floor (11) falling off can be solved.

It is not necessary to install the rigid three-dimensional frame (3) in all the rooms in the house, but it is sufficient to install it in a necessary room such as a sleeping room within the range of the budget. Therefore, compared to rebuilding the entire house The economic burden is far smaller.

In carrying out the present invention, as shown in FIG. 5, in the case of a one-story house, the bottom frame (4) of the rigid three-dimensional frame (3) is assembled on the dirt floor (7) under the floor (11), The lower part of the main rod (5) and the reinforcing rod (51) can be connected to the bottom frame (4) by penetrating the floor (11) of the room (2). In this case, the problem of the floor (11) falling out can be solved. The present invention is not limited to the configuration of the above embodiment, and various modifications can be made within the scope of the claims for utility model registration.
