Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention minimizes damage by spreading the pressure caused by a blast in the event of an explosion accident in a building such as a battery factory where an explosion accident may occur. It relates to the structure of a building that has been equipped with measures against explosions.

[0002]

2. Description of the Related Art Conventionally, as a measure against a building when an explosion accident occurs, for example, a roof material is made of a material having low strength, and the roof wall is destroyed by a pressure of a blast. It is generally known that the structure of a building reduces the power of explosion by spreading the pressure to the outside.

Alternatively, a member such as a wall material that constitutes a building is provided with an extreme difference in strength between the members, for example, by combining an RC wall and a slate ceiling, and the strength of the member is increased by the pressure due to the explosion as in the above case. There is also known a structure of a building that destroys low members to diffuse pressure to the outside and reduce the power of explosion.

[0004]

In these conventional examples of the building provided with measures against explosion, it is generally assumed that the frequency of explosion accidents is low, and the building can be easily constructed after the explosion accident. No consideration is given to restoration. In other words, there is a problem in that, in the unlikely event of an explosion accident, the building must be repaired at great expense and time.

Further, no consideration has been given to preventing an accident caused by a scattered object due to an explosion, and there is also a problem that damage caused by the scattered object is widened when an explosion accident occurs.

[0006] Therefore, in the case of a building in which measures against an explosion accident in the conventional example have been taken, it is possible to easily repair and restore the building after the explosion accident, and to prevent damage caused by scattered objects at the time of the explosion. Has challenges that must be addressed.

[0007]

As a concrete means for solving the above-mentioned problems of the prior art, the present invention is a building provided with a door that opens and closes to the outside of an outer wall through a hinge with respect to a door frame. , A free end of the door is provided with a French dropper having a projecting rod at a receiving seat provided at an upper portion or a lower portion of the door frame, and the outer peripheral surface of the rod receives a predetermined pressure due to an explosion. The present invention provides a structure of a building having a countermeasure against explosion, which is characterized in that a concave defect portion that breaks off is formed.

Further, the partition wall provided inside the building is constructed by arranging high-strength panels, and the inner door provided inside the building has a high-strength proof strength. In addition, a high-strength panel is arranged inside the outer wall, and a fence that receives scattered materials due to an explosion is provided outside the door.

In the structure of the building against the explosion according to the present invention, the rod dropped in France is formed with a defective portion that breaks when a predetermined pressure is applied, so that the rod is broken by the pressure of the blast and the door is opened at the same time. Is released to the outside and the pressure diffuses, so the power of the explosion can be reduced. Repairs are completed simply by replacing the broken rods, and the building can be restored easily and quickly.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described with reference to the drawings. First, in FIGS. 1 and 2, reference numeral 1 denotes a building provided with an explosion countermeasure, and the building 1 is opened to the outside through a hinge 4 with respect to an outer wall 2 and a door frame 3 attached to the outer wall 2. It has a door 5 for opening, a partition wall 7 for partitioning the inside of the building 1 into a plurality of rooms 6, and an inner door 8 provided inside the building 1.

The outer wall 2 is formed by arranging a plurality of ALC plates. Inside the outer wall 2, for example, positive and negative 28
A high-strength panel 9 of about 0 kgf / m ² is provided to improve the strength of the outer wall 2.

As the door 5, a steel door (SD) having a proof stress of, for example, about 142 kgf / m ² is used, and the free end side 5a of the door 5 is as shown in FIGS. 2 and 3. A French dropper 12 having a projecting rod 11 is provided on a receiving seat 10 provided on the upper portion or the lower portion of the door frame 3.

As shown in FIG. 4, on the lower end side of the rod 11, a concave defect 13 is formed along the outer peripheral surface. The defect 13 causes a predetermined pressure due to the explosion of the door 5. It is strong enough to break when received.

Specifically, the defective portion 13 is adjusted so as to break when it receives a wind pressure strength of about 100 kgf / m ^2, and at the same time when the rod 11 breaks due to an explosion, the door 5 is opened to the outside and the pressure is reduced. It can spread and reduce the power of explosions.

The partition wall 7 is, for example, positive / negative 280 kgf / m ²
A plurality of high-strength panels are arranged to form the partition wall 7, thereby improving the strength of the partition wall 7.

The inner door 8 is a high strength steel door (SD)
Is used, and specifically, it is formed with a proof stress of, for example, about 200 kgf / m ² . Also, the inner door 8
It is preferable to use Clemon tablets (not shown),
In this case, the airtightness of the room can be improved.

On the outside of the door 5, there is provided a fence 14 for receiving scattered objects caused by an explosion, and the fence 14 can prevent damage caused by the scattered objects at the time of explosion. It should be noted that reference numeral 15 in FIG. 1 denotes a passage provided outside the inner door 8, and reference numeral 16 denotes an entrance provided at the passage 15.

As described above, by forming the defective portion 13 on the rod 11 of the French drop 12 of the door 5, the defective portion 13 is broken by the pressure of the blast and at the same time the door 5 is opened to the outside to diffuse the pressure. Therefore, the power of the explosion can be reduced, and the broken rod 11
Repairs can be done simply by replacing the building, so the building can be restored easily and quickly.

The partition wall 7 is formed by arranging high-strength panels, the inner door 8 is made of a material having high strength, and the inner wall 8 has high strength. Since the panel 9 is provided, no damage is caused by the explosion except the rod 11 of the door 5.

[0020]

As described above, the structure of a building provided with explosion protection according to the present invention is a building provided with a door that opens and closes to the outside of the outer wall through a hinge with respect to the door frame. , A free end of the door is provided with a French dropper having a projecting rod at a receiving seat provided at an upper portion or a lower portion of the door frame, and the outer peripheral surface of the rod receives a predetermined pressure due to an explosion. and by forming the concave defect which Oridan, since the rod by the blast pressure diffusion is opened door outside and at the same time Oridan, it is possible to reduce the power of the explosion. The repair is completed simply by exchanging the broken rod, and the excellent effect that the building can be restored easily and quickly is achieved.

Further, the partition wall provided inside the building is formed by arranging high-strength panels, and the inner door provided inside the building is one having high strength resistance, The high-strength panel is installed inside the outer wall, so that the pressure due to the blast diffuses from the door that opens to the outside of the building as described above. Has the excellent effect of not being damaged by the explosion.

Further, by providing a fence on the outside of the door for receiving the scattered matter due to the explosion, it is possible to prevent the damage caused by the scattered matter at the time of the explosion.
