Description

  The present invention relates to a disaster prevention shelter that can protect residents from dangers such as collapse of a house due to an earthquake.

  The collapse of the house caused by the earthquake led to overwhelming death, and there were many people who were overwhelmed by the previous earthquake. On the other hand, it has become possible for general citizens to issue an earthquake warning immediately after the occurrence of a P wave by means of an emergency earthquake warning or an earthquake alarm.

However, the fact is that the residents do not have a definite place to escape even if a warning is issued. As countermeasures, various disaster prevention shelters (also referred to as disaster prevention bed frames and disaster prevention beds) have been provided that can be installed outside sleeping supplies such as beds to protect those who sleep from falling.
The concrete thing is the disaster prevention shelter shown in FIG. 6 thru | or FIG. 9 which this applicant implemented previously.
This disaster prevention shelter is of a steel framework type in which a sleeping product 1 which is a bed is installed and a person sleeping on the sleeping product 1 is protected from a collapse of a house during an earthquake.
The disaster prevention shelter is composed of two steel round pipe columns 3, 3 and the upper part of the same, and a flat frame bottom frame 5 that connects between the steel frame upper frame 4 and the bottom of the columns 3, 3. And a pair of main frames 6 and 6 which are formed in a trapezoidal (gate-shaped) frame shape whose upper portion is narrowed, and are erected and arranged opposite to each other in the longitudinal direction of the sleeping article 1.
A protective frame body 8 that is bridged between a back surface corresponding to one side of the sleeping product 1 and a top surface that connects between the pair of front and rear upper frame portions 4 with respect to the open doorway side (arrow display side in FIG. 6). And have. Reference numeral 9 denotes a middle connecting frame.

By the way, as shown in FIG. 9, the main frame 6 was formed by bending a long round pipe at two places and forming it into an integral frame shape. Since the finished dimensions of the front and rear main frames 6 and 6 are different at the time of assembling a set of disaster prevention shelters, the dimensions of the protective frame body are assembled via the grooved steel seats 10. There was also a problem that 8 was stopped in a twisted state. In this case, the protective frame 8 is also a combination of a plurality of horizontal rails 11 and vertical members 12 in a lattice shape, but this protective frame 8 is integrally formed in a reverse side L shape. Therefore, the dimensional finish itself has a disadvantage that it is mounted in a manner that is difficult to match both the main frames 8 and 8, and correction is required at the installation site, which takes time to install. Since a plurality of bending members are used in a part of the vertical member 12, this is a factor that is expensive.
In addition, since the protective frame 8 has a single side surface and top surface, it is very heavy, and mounting work on the main frame 6 at the site is difficult.

Further, a protective face material 10 is attached to the inner surface of the protective frame body 8 so as to protect a person who goes to bed against a fallen object or a scattered object from the outside. In addition, since the one that is integrally bent into the inverted L shape is used, the work is required to be expensive and complicated to assemble to the protective frame 8.
The present invention has been made in view of the above, and it is possible to improve the dimensional finishing accuracy of each member so that the construction at the site is appropriate and strong, and the excessive weight of the constituent members is eliminated. The purpose of this invention is to provide an inexpensive disaster prevention shelter that can be easily and reliably installed on site by reducing the weight.

  In order to solve the above-mentioned problem, the invention according to claim 1 is a steel frame type disaster prevention shelter for protecting a person sleeping on the sleeping article from being collapsed by an earthquake. It is formed in a trapezoidal frame shape with the upper part narrowed by the upper frame part that connects between the top part of the book and the upper part and the bottom frame part that connects the bottom part of the support part, and stands upright in the longitudinal direction of the sleeping item. A pair of main frames to be arranged; a protective frame body spanned between a back side surface corresponding to one side of a sleeping item and an upper side connecting a pair of front and rear upper frame portions; The main frame is an integrally formed product in which the column part on the entrance and exit sides and the upper frame part are formed through a bent part, and the remaining column on the back side is a separate straight pipe, It is integrally connected to the end on the back side so as to cross diagonally, The frame is divided into two frames, a side protection frame and a top surface protection frame, and the side protection frame is attached so that the front and rear of the support composed of the straight pipes follow the support in parallel. The top protection frame is characterized in that a portion between a pair of front and rear upper frame portions is attached in parallel to the upper frame portions.

  According to this invention, a sleeping frame is installed in the interior, and the steel frame type disaster prevention shelter for protecting a person sleeping on the sleeping product from collapse of a house at the time of an earthquake is provided between two struts and the upper part thereof. A pair of main frames that are formed in a trapezoidal frame shape whose upper part is narrowed by the upper frame part to be connected and the bottom frame part that connects between the bottom parts of the column parts, and are arranged so as to be opposed to each other in the longitudinal direction of the sleeping item; The main frame has a protective frame that is bridged between a back side surface corresponding to one side of the sleeping item and a top surface that connects between the upper and lower pair of upper frame portions. The strut portion on the entrance / exit side and the upper frame portion are integrally formed through a bent portion, and the remaining strut on the back side is a separate straight pipe and obliquely intersects the end on the far side of the upper frame portion. The protection frame body is integrally connected to the side protection frame and the top surface protection. The side protection frame is attached so that the front and rear of the pillars made of straight pipes are attached in parallel to the pillars, and the top surface protection frame is a pair of front and rear upper frames. It is characterized in that the frame portion is attached so as to follow the upper frame portion in parallel, so that the dimensional finishing accuracy of each member can be improved and the construction at the site is made appropriate and strong. In addition, an inexpensive disaster prevention shelter can be provided which can easily and surely perform installation work on site by eliminating the excessive weight of components and reducing the weight.
