Description

  The present invention relates to a heat-resistant structure for protecting a joint of a tubular body that allows water to flow from the heat of a flame and preventing the damage at a fire site.

  Oil leakage fires (fires generated by igniting oil leaked from storage facilities, etc.) are extremely fast due to their physical and scientific properties, and it is extremely difficult to extinguish them after the scale has expanded. Therefore, it is important to prevent the spread of fire by preventing the leakage of combustion leakage oil until it is ready to extinguish. Therefore, the present applicant has proposed as a Japanese Patent Application No. 2006-155067 a fire spread prevention method and a fire spread prevention device used in the method that are effective in the early stage of an oil leakage fire.

According to this fire spread prevention method, a deformable and long cylindrical body is used to divide the disaster prevention target area from the disaster area, and to form a guiding area continuous with the disaster area, thereby generating combustion leakage oil. By guiding from the disaster area to the guidance area, it is possible to prevent the fire from spreading to the disaster prevention target area that may spread. At this time, water is oozed out from the wall surface of the cylinder that forms the guidance area that is separated from the disaster prevention target area and the disaster area, and the wall surface of the cylinder is covered with a film of the oozed water. Thus, it is possible to protect the cylinder from the heat of the flame, prevent its damage, and maintain the state and the guidance area in which the disaster prevention target area and the disaster area are separated. In addition, by storing the water that has oozed out in the disaster area and the induction area, the combustion leakage oil can be burned on the water surface to keep the oil temperature low, and the flame momentum can be suppressed. Furthermore, by keeping the water level of the accumulated water within a range that does not exceed the height of the cylinder, the combustion leakage oil does not flow over the cylinder and flow into the disaster prevention target area.
Japanese Patent Application No. 2006-155067

  The cylindrical body used in the method for preventing the spread of fire may be any deformable and long one that allows water to ooze out from the wall surface, and a general fire hose with a waterproof lining removed can be adopted. On the other hand, the cylinder that separates the disaster prevention target area and the disaster area needs to be able to be arranged in various shapes according to the disaster situation. In some cases, it is necessary to connect the cylinders using a connector. Cases are also conceivable. Therefore, if a joint used for a general fire hose can be adopted for the connector, it is possible to divert a technique related to a known water flow hose typified by a fire hose to the fire spread prevention method.

  However, the known joint does not have a structure that allows water to ooze out from the wall surface, and cannot protect from the heat of the flame by using the oozed water film. In addition, the diameter is larger than the diameter of the cylinder to be connected, and a gap is formed when the cylinder is separated from the ground in the vicinity of the joint, so that water can be collected in the vicinity of the joint. could not. For this reason, if a known joint is used as it is in the method for preventing the spread of fire, it may be damaged by the heat of the flame.

  Therefore, an object of the present invention is to provide a heat-resistant structure that does not include a structure that allows water to ooze out from the wall surface, and that can protect a joint having a diameter larger than the diameter of the cylinder to be connected from the heat of the flame. Objective.

The first heat-resistant structure according to the present invention has a deformable and long cylindrical body in which water seeps out from the wall surface, and a diameter larger than the diameter of the cylindrical body attached to the end of the cylindrical body. The joint is composed of a cloth in which a pair of opposing edges are detachable, and a set of fasteners for fixing the cloth to the cylindrical body. In a state where two of the cylinders are connected via the joint and placed on the ground, and the vicinity of the joint of the cylinder is separated from the ground, the joint and the ground in the vicinity of the joint of the cylinder The free part away from the cover is covered with the cloth formed by bonding the edge part into a cylindrical shape. The cloth is grounded over the entire length in the longitudinal direction of the cylindrical body, and both ends opened in the longitudinal direction of the cylindrical body are fixed to the cylindrical body by the fasteners.

The second heat-resistant structure according to the present invention has a deformable and long cylindrical body that allows water to ooze out from the wall surface, and a diameter larger than the diameter of the cylindrical body attached to the end of the cylindrical body. A joint, a relay joint for connecting the joints, a cloth having a pair of opposing edges detachable, and a fastener for fixing the cloth to the cylinder or the relay joint. The In the state where two of the cylinders are connected via the joint and the relay joint and are placed on the ground, and the vicinity of the joint of the cylinder is separated from the ground, the joint and the body of the relay joint The connecting portion extending from the portion and the free portion away from the ground in the vicinity of the joint of the cylindrical body are covered with the cloth having a tubular shape by bonding the edge portion. Also, the fabric is adapted to ground in the longitudinal direction of the length of the tubular member, the one of which the tubular member end opening in the longitudinal direction of the tubular member, the other is the relay joint,該締fastening It is fixed by crimping with the dressing.

The third heat-resistant structure according to the present invention includes a deformable and long cylindrical body that allows water to ooze out from the wall surface, the water pipe, the cylindrical body, and the cylindrical body attached to the end of the water pipe. A joint having a diameter larger than the diameter of the joint, a relay joint for connecting the joints, a cloth having a pair of opposing edges detachable, and fixing the cloth to the cylindrical body or the relay joint It is made up of fasteners. In a state where two of the cylinders and the water pipe are connected via the joint and the relay joint and are placed on the ground, and the vicinity of the joint of the cylinder is away from the ground , The connecting portion extending from the main body portion of the relay joint and the free portion away from the ground in the vicinity of the joint of the cylindrical body are covered with the cloth having a tubular shape by bonding the edge portion. In addition, the cloth is grounded over the entire length in the longitudinal direction of the cylindrical body, and an end portion that opens in the longitudinal direction of the cylindrical body is on the cylindrical body, and an end portion that opens in the longitudinal direction of the water supply pipe is A heat-resistant structure, wherein the heat-feed pipe is fixed by crimping with the fastener.

  The cloth may be a heat resistant cloth.

  The fastener may be formed of an elastically deformable annular member having a discontinuous portion.

According to the first heat-resistant structure according to the present invention, the joint attached to the end of the cylindrical body is covered with the cylindrical cloth, and both ends of the cylindrical cloth open are cylindrical. Therefore, a space surrounded by a cloth is formed around the joint. Moreover, since this space includes a part (free part) of the cylindrical body, the water that exudes from the wall surface of the cylindrical body fills this space. Therefore, the joint is protected from the heat of the flame by the water filled in this space.
On the other hand, a cylindrical cloth covering the joint is grounded over the entire length in the longitudinal direction of the cylinder, a gap between the cylinder formed in the vicinity of the joint and the ground, and a place where water exuded from the wall surface of the cylinder accumulates. Becomes discontinuous. And the water which oozes out from the wall surface of the cylindrical body is filled in the vicinity of the joint through this gap, and starts to ooze again from the surface of the cylindrical cloth. This exuding water protects the tubular fabric from the heat of the flame and prevents its damage, so that the joint can also be protected from the heat of the flame.

  According to the second and third heat-resistant structures according to the present invention, when the joint attached to the end portion of the cylinder is connected via the relay joint, specifically, a three-way pipe joint is used. In the case where the cylinder is trifurcated, the joint can be protected in the same manner as the first heat-resistant structure.

First, in the case of the second heat-resistant structure, the joint attached to the end of the cylindrical body is covered with a tubular cloth together with a connecting portion extending from the main body portion of the relay joint, and further, the tubular shape. Since the end of the cloth that is opened is crimped and fixed to the cylinder or the relay joint with a fastener, a space surrounded by the cloth is formed around the connection portion between the joint and the relay joint. Moreover, since this space includes a part (free part) of the cylindrical body, the water that exudes from the wall surface of the cylindrical body fills this space. For this reason, the joint is protected from the heat of the flame by the water filling the space together with the connecting portion of the relay joint. In the present invention, the tubular shape may be any structure as long as it is surrounded by a peripheral wall and has a space having an opening at the end of the peripheral wall. Including those having openings.
On the other hand, a tubular cloth covering the joint and the connecting portion is grounded over the entire length in the longitudinal direction of the cylinder, and the water that exudes from the gap between the cylinder and the ground formed near the joint and the wall surface of the cylinder The location where it accumulates is discontinuous. And the water which oozes out from the wall surface of the cylindrical body is filled in the vicinity of the joint through this gap, and starts to ooze again from the surface of the tubular cloth. This exuding water protects the tubular fabric from the heat of the flame and prevents its damage, so that the joint and the connecting part can also be protected from the heat of the flame. Although the main part of the relay joint is exposed without being covered with the cloth, since this part is originally high in strength, it is unlikely to be damaged by the heat of the flame, and this is not a problem in practice.

  In the case of the third heat-resistant structure, the basic function and effect are the same as those of the second heat-resistant structure, and there is a space encompassing a part of the cylinder surrounded by a cloth around the joint for connecting the joint and the relay joint. The water that is formed and oozes out from the wall surface of the cylinder fills this space, and the joint and the connecting portion are protected from the heat of the flame by the water. In addition, if the water accumulated in the space starts to ooze from the surface of the cloth, the spilled water protects the tubular cloth from the heat of the flame and prevents its damage. The joint and the connecting portion can be protected from the heat of. However, the third heat-resistant structure is used when a water pipe is used to efficiently supply water to a line in which deformable and long cylinders are installed. This is different from the second heat-resistant structure in that it also includes the configuration of The joint and the connecting portion arranged at the position directly facing the flame need to be protected, but the joint and the connecting portion arranged on the side (back side) not facing the flame of the cylindrical body are not necessary. Therefore, when water is supplied to the line where the cylinder is to be placed from the back side of the cylinder using the water pipe, the joint and the connecting portion relating to the water pipe and the water pipe need not be originally protected, and therefore the cloth There is no need to cover with. However, in order to form a space capable of holding water around the joint and the connecting portion arranged at a position directly facing the flame, both the parts that are not originally protected are also covered. The second heat-resistant structure has the advantage that it can be constructed more easily than the third heat-resistant structure with fewer parts to be covered with the cloth, whereas the third heat-resistant structure has the advantage that the body part of the relay joint can also be covered. .

  If the cloth is a heat-resistant cloth, the function of protecting the joint can be enhanced.

  Further, if the fastener is made of an elastically deformable annular member having a discontinuous portion, the cloth can be fastened by simply fitting it from above the cloth covering the joint and the cylinder. It can be crimped to the cylinder. Therefore, it can be suitably used also in a method for preventing the spread of an oil leak fire, which has a fast fire expansion rate.

  A specific example of the first heat-resistant structure according to the present invention will be described with reference to FIGS. 1 is a front view showing the heat resistant structure, FIG. 2 is a perspective view showing a cloth constituting the heat resistant structure, FIG. 3 is a perspective view showing a fastener constituting the heat resistant structure, and FIG. It is a top view which shows the outline of the adopted disaster site.

  As shown in FIG. 4, this specific example is shown in a facility that handles a flammable liquid, a site where a disaster occurred in one of two facilities arranged side by side, more specifically, an oil loading facility in a tank lorry. It was adopted at the site where the disaster occurred on one of the two arranged islands. At this disaster site, there is only one disaster prevention target area 14, and the disaster prevention area 15 and the disaster prevention target area 14 are separated by connecting two cylindrical bodies 1 and ooze out from the wall surface of the cylindrical body 1. Water accumulates on a surface surrounded by the foundation of the island and the cylinder 1 in the disaster area 15. On the other hand, in the induction region 17, which is a region where the combustion leakage oil 13 can be safely burned, a puddle in contact with the cylindrical body 1 is formed, and the puddle spreads in the induction region 17. The water 16 stored as a puddle enables the combustion leakage oil 13 to be guided, and functions to keep the oil temperature of the combustion leakage oil 13 low. In addition, in order to guide the fuel leaking oil 13 to the guidance area 17 at the disaster site, a normal fire hose is used from an oblique rear side of the disaster area 15 with the side in contact with the guidance area 17 of the disaster area 15 as the front. The water should be discharged. (The white arrow in FIG. 4 indicates the direction of water discharge)

  The two cylinders 1 are connected by a detachable joint 2 attached to the ends of the cylinders 1. And in the connection part 11 of the cylinder 1 containing this joint 2, the heat-resistant structure of this specific example is employ | adopted.

  This heat-resistant structure includes the tube 1, the joint 2, a cloth 3 in which a pair of opposed edge portions 3 a is detachable, and a set of fastenings that fix the cloth 3 to the tube 1. It is comprised with the ingredient | tool 4. The joint 2 is disposed on the ground in an engaged state, and is covered with a cloth 3 having a cylindrical shape by adhering the edge 3a together with a free portion 1a that is separated from the ground in the vicinity of the joint 2 of the cylindrical body 1. The cylindrical cloth 3 is grounded over the entire length in the longitudinal direction X of the cylindrical body 1, and both open ends 3 b and 3 b of the cylindrical cloth 3 are crimped to the cylindrical body 1 by the fastener 4. It is fixed.

According to this heat-resistant structure, the joint 2 attached to the end portion of the cylindrical body 1 is covered with the cylindrical cloth 3, and the both ends 3 b and 3 b of the cylindrical cloth 3 are opened. Since the body 1 is fixed by crimping with the fastening tool 4, a space 5 surrounded by the cloth 3 is formed around the joint 2. Further, since this space 5 includes a part of the cylindrical body 1 (free portion 1 a), the water that oozes out from the wall surface of the cylindrical body 1 fills this space 5. Therefore, the joint 2 is protected from the heat of the flame by the water filled in the space 5.
On the other hand, the cylindrical cloth 3 covering the joint 2 is grounded over the entire length of the cylindrical body 1 in the longitudinal direction X, and stains from the gap 6 between the cylindrical body and the ground formed near the joint 2 and the wall surface of the cylindrical body 1. The place where the discharged water accumulates (in this specific example, the guidance region 17) is discontinuous. Then, the water that has oozed out from the wall surface of the cylindrical body 1 is filled in the vicinity of the joint 2 through the gap 6 and starts to ooze from the surface of the cylindrical cloth 3 again. This exuded water protects the tubular fabric from the heat of the flame and prevents its damage, so that the joint 2 can be protected from the heat of the flame.

One set of the edge 3a which the cloth 3 opposes is detachable by the hook-and-loop fastener 7a provided along the edge 3a.
Moreover, the cloth 3 employs a heat resistant cloth for fire extinguishing suffocation (Fire Stop: manufactured by Asahi Fiber Glass Co., Ltd.). In this case, since the cloth has heat resistance, the function of protecting the joint 2 can be enhanced. However, as long as it is a cloth that can maintain the water level of the water oozed from the cylindrical body 1, it does not have to have heat resistance, and a normal close-knit cloth may be adopted.

  The fastener 4 is formed of an elastically deformable annular member having a discontinuous portion 4a formed by cutting a part of an elastic ring. In this case, the cloth 3 can be fixed in a short time just by fitting from above the cloth 3 covering the joint 2 and the cylindrical body 1. Therefore, it can be suitably used also in a method for preventing the spread of an oil leak fire, which has a fast fire expansion rate. However, the structure of the fastener 4 is not limited, and any structure can be used as long as the two openings 3b of the tubular cloth 3 can be fixed to the tubular body 1 by pressure bonding. Note that it is preferable that the fastening tool 4 is integrally formed with the cloth 3 by sewing or the like because the mounting speed can be increased.

  A specific example of the third heat-resistant structure according to the present invention will be described with reference to FIGS. FIG. 5 is a plan view showing the heat resistant structure, FIG. 6 is a plan view showing a preparation state when the heat resistant structure is not in use, FIG. 7 is a perspective view showing a cloth constituting the heat resistant structure, and FIG. It is a top view which shows the outline of the disaster site where the heat-resistant structure was employ | adopted. In addition, the same code | symbol is attached | subjected to the substantially same part as the specific example shown in FIGS. 1-4, and the description is abbreviate | omitted or simplified.

  In this specific example, as shown in FIG. 8, the area around the affected facility is used in a disaster site where the area 14 is a disaster prevention target area 14. Since there is a distance to the adjacent facilities at the disaster site, the guide area 17 is a circle having the maximum diameter in a range that does not affect the disaster prevention target area 14 by the flame. Then, the high pressure water is supplied to the cylindrical body 1, the high pressure water is oozed out of the wall surface of the cylindrical body 1 while maintaining the swollen state of the cylindrical body 1, and the wall surface is covered with a film of the exuded water and the disaster area 15 and the induction area 17 are collected, and the leakage oil 13 is guided from the disaster area 15 to the induction area 17 while keeping the water level of the accumulated water 16 within a range not exceeding the height of the cylinder 1. ing.

  The cylindrical body 1 is an annular structure in which two ends, each having a detachable joint 2 attached thereto, are connected by a connecting portion 11 and a joint portion 18, and the cylindrical body 1 including the joint 2 is provided. In the connecting portion 11, the same heat resistant structure as that of the specific example shown in FIGS.

  On the other hand, in the joint portion 18, the joint 2 attached to each end portion of the two cylinders 1 and the joint 2 attached to the end portion of the water supply pipe 9 where water does not ooze out from the wall surface. Are connected via a three-way pipe joint adopted as the relay joint 8. And in this joining part 18, the heat-resistant structure of this specific example is employ | adopted.

  As shown in FIG. 5, in this heat-resistant structure, a set of the cylindrical body 1, the water pipe 9, the joint 2, the relay joint 8, and the facing edge 3a is detachable. The cloth 3 and the fastener 4 that fixes the cloth 3 to the cylinder 1 or the relay joint 8 are configured. The joint 2, the connecting portion 8 b extending from the body portion 8 a of the relay joint 8, and the free portion 1 a that is separated from the ground in the vicinity of the joint 2 of the cylinder 1 are bonded to the edge 3 a to form a tubular cloth 3 is covered. The cloth 3 is grounded over the entire length in the longitudinal direction X of the cylindrical body 1, and the end portions 3 b and 3 b that open in the longitudinal direction X of the cylindrical body 1 are connected to the cylindrical body 1 and the longitudinal direction Y of the water supply pipe 9. An end 3 c that is open to the water pipe 9 is fixed to the water supply pipe 9 by a fastener 4.

According to this heat resistant structure, the joint 2 attached to the ends of the cylinder 1 and the water pipe 9 is covered with the tubular cloth 3 together with the connecting portion 8b extending from the main body portion 8a of the relay joint 8. Furthermore, since the open ends 3b and 3c of the tubular cloth 3 are fixed to the cylinder 1 or the water supply pipe 9 by the fastening tool 4, the cloth is formed around the joint 2 and the connecting portion 8b. A space 5 surrounded by 3 is formed. Further, since this space 5 includes a part of the cylindrical body 1 (free portion 1 a), the water that oozes out from the wall surface of the cylindrical body 1 fills this space 5. Therefore, the joint 2 is protected from the heat of the flame by the water filled in the space 5 together with the connecting portion 8b.
On the other hand, the tubular cloth 3 covering the joint 2 and the connecting portion 8b is grounded over the entire length in the longitudinal direction X of the cylindrical body 1, and the gap between the cylindrical body 1 formed near the joint 2 and the ground (not shown) ) And a place where water exuded from the wall surface of the cylindrical body 1 is in a discontinuous state. And the water oozed out from the wall surface of the cylinder 1 is filled in the vicinity of the joint 2 and the connecting portion 8b through this gap, and starts to ooze out from the surface of the tubular cloth 3 again. Since the exuded water protects the tubular cloth 3 from the heat of the flame and prevents the damage, the joint 2 and the connecting portion 8b can be protected from the heat of the flame.

  As the cloth 3 used for this heat-resistant structure, for example, as shown in FIG. 7, a cloth composed of a flat portion 3d and a cylindrical portion 3e may be used. And in order to cover the joint 2 and the connection part 8b, what is necessary is just to mount | wear with the relay joint 8 in the state before using previously. At this time, it is preferable to roll up the end portions 3b, 3b, and 3c toward the main body portion 8a as shown in FIG. 6 so as not to hinder the connection work between the cylindrical body 1 and the water pipe 9. Moreover, it is preferable to make the notch 3f in the site | part used as the edge parts 3b, 3b, and 3c so that a clearance may not be made when it crimps and fixes to the cylinder 1 and the water pipe 9. As shown in FIG. 6, the cut 3f is preferably arranged on the upper surface side (opposite the surface where the relay joint 8 contacts the ground). In this case, even if the cut 3f is slightly opened, the water in the space 5 remains on the upper surface. Only overflow from the side, and the space 5 can be filled with water without any trouble. Furthermore, it is preferable that the edge portion 3a is detachable by a fastener 7b made of contactable and separable engaging teeth, which is more easily deformed than a surface fastener, so that the end portions 3b and 3b can be rolled up. At this time, the fastener 7b is preferably provided in the vicinity of the tubular portion 3e so as to be disposed on the side (back side) that does not face the flame of the tubular body 1.

  A specific example of the second heat-resistant structure according to the present invention will be described with reference to FIG. FIG. 9 is a front view showing the heat resistant structure. In addition, the same code | symbol is attached | subjected to the substantially same part as the specific example shown in FIGS. 1-8, and the description is abbreviate | omitted or simplified.

  This heat resistant structure is employed at the same disaster site as the heat resistant structure shown in FIGS. 5 to 8, and is at the joint 18 between the circular cylindrical body 1 and the water pipe 9. However, as the cloth 3 covering the joint 2 and the connecting portion 8b, the same structure as the heat resistant structure shown in FIGS. 1 to 4 is used, and the structure on the water supply pipe 9 side disposed at a position not directly facing the combustion leakage oil 13 is used. Is different from the heat resistant structure shown in FIGS. That is, without including the water pipe 9 in the configuration, the end portions 3b and 3b of the cloth 3 surrounding the joint 2 and the connecting portion 8b that open in the longitudinal direction X of the cloth 3 are formed in the cylindrical body 1 or the relay joint 8. It is fixed by crimping with a fastener 4. In addition, in FIG. 9, the water pipe 9 side opening of the main-body part 8a is shown with a broken line.

  In the case of this heat resistant structure, similarly to the heat resistant structure shown in FIGS. 5 to 8, a space containing a part of the cylindrical body 1 (floating portion 1 a) surrounded by a cloth around the joint 2 and the connecting portion 8 b. The water that is formed and oozes out from the wall surface of the cylindrical body 1 fills this space 5, and the joint and the connecting portion are protected from the heat of the flame by the water. In addition, if the water accumulated in the space starts to ooze from the surface of the cloth, the spilled water protects the tubular cloth from the heat of the flame and prevents its damage. The joint and the connecting portion can be protected from the heat of. And since it can construct | assemble easily, without covering the site | part which does not need protection originally, it can utilize suitably also in the fire-spreading prevention method of the oil leak fire with a high speed of fire expansion. The main body 8a of the relay joint 8 is exposed without being covered with the cloth 3. However, since this portion has high strength, the possibility of being damaged by the heat of the flame is low, which does not cause a problem in practice. . In addition, it is preferable to provide a groove suitable for the fastener 4 at the attachment position of the fastener 4 in the main body portion 8a of the relay joint 8. In this case, leakage due to the positioning of the fastener 4 is prevented. it can.
