Description

[0001]
[Technical field to which the invention belongs]
The present invention includes a fire extinguishing liquid, a fire extinguishing liquid jet nozzle facing downward, and a simple automatic fire extinguisher of the type that senses an abnormally high temperature and sprays the fire extinguishing liquid from the ceiling. The present invention relates to a fire extinguisher mounting structure.
[0002]
[Prior art]
Conventionally, when installing a fire extinguisher on the ceiling, a special field edge for fixing the fire extinguisher was separately installed, and the fire extinguisher was attached to this field edge. Alternatively, the fire extinguisher is fixed to the ceiling by suspending it from the floor structure on the upper floor above the ceiling by means of a bar-like member. Japanese Patent Application Laid-Open No. 12-116810 discloses a method of using a main body fixture having an L-shaped angle that is placed between the top edges of the ceiling and placed on the top face of the top. In any case, a type in which the fire extinguisher main body is stored behind the ceiling while leaving the fire-extinguishing liquid spray nozzle and the sensor is preferable in terms of appearance.
[0003]
[Problems to be solved by the invention]
However, providing a special field edge or a rod-like member for fixing the fire extinguisher requires a great deal of labor for mounting the fire extinguisher. Moreover, since the method disclosed in Japanese Patent Application Laid-Open No. 12-116810 also uses an L-shaped angle protruding from the fire extinguisher body, it becomes large to be inserted from an opening drilled in the ceiling, There was a problem that the insertion work became difficult. Furthermore, recently, there are houses that have only insufficient space for the fire extinguisher main body to be stored behind the ceiling. In this case, the entire fire extinguisher is exposed, and there is a problem in appearance.
[0004]
In addition, the field edge includes a wooden field edge and a steel sheet field edge. Generally, the steel sheet field edge is about 40 to 60 mm, and the wooden field edge is about 10 to 30 mm. Also, the height of the back of the ceiling varies greatly, and it was necessary to attach an automatic fire extinguisher by a simple method under various conditions including these.
[0005]
[Means for Solving the Problems]
The present invention has an object to solve the above-mentioned problems, and has a configuration in a ceiling-mounted automatic fire extinguisher mounting structure, in which a hook-shaped engagement portion is outward from the two most distant sides near the outer edge of the fire extinguishing liquid tank. The engaging tool extends upward, both ends are made of horizontal plates, and a concave portion that can be fitted into the opening of the ceiling is formed at the center, and the bottom surface of the concave portion has a pair of bridges parallel to the horizontal plates at both ends. The hollow column body is extended upward at one portion of the vertical descending portion where the bottom surface of the concave portion of the bridge and the horizontal plate are joined, and the horizontal connection portion extending from the column body, and the tip of the connection portion An eaves engaging member having a height adjusting function with an eaves receiving plate extending upward is extended, and the eaves receiving plate has a wider engaging surface than the eaves-like engaging device at the center portion at both ends. Square projections extend, and the horizontal plates at both ends of the bridge are stable between adjacent field edges on the top surface of the ceiling to be secured. Characterized in that placing it in length.
[0006]
In other words, the present invention comprises two bridges in which a single hollow column body provided with a hook engaging member is shifted to one end of the bottom surface of the recess. The bridge consists of horizontal plates at both ends, forming a recess that can be fitted into the opening of the ceiling at the center, the bottom surface of the recess is parallel to the horizontal plates at both ends, and the horizontal plates at both ends of the bridge are the top surface of the ceiling to be fixed It is a length that can be stably placed on the adjacent field edge.
A hook-shaped engagement tool with an engaging portion extending outward from the two most distant sides in the vicinity of the outer edge of the fire extinguishing liquid tank extends upward, engages with the hook-shaped engagement tool, and can be moved up and down. The fire extinguishing liquid tank is reliably suspended on the bridge by providing the engaging tool on the hollow column.
By using this bridge, a long bridge and a heavy fire extinguisher main body can be separately inserted into the ceiling, and can be attached only by suspending the ridge on the support plate.
[0007]
The hollow column body is open on the side where the hook receiving engagement tool is provided, and means for moving the hook receiving engagement tool up and down is provided. As a result, the fire extinguishing liquid tank can be suspended and installed at the optimum site regardless of the thickness of the field edge.
In addition, when the space behind the ceiling is insufficient, it is possible to store only the portion of the fire extinguisher main body that enters the back of the ceiling and attach the remaining portion in a protruding state. In this case, a bridge in which the length of the hollow column body is shortened may be used so that the bridge having the hollow column body can be installed on the back of the ceiling. If the fire extinguisher cannot fully enter the ceiling, the problem of appearance can be solved by deepening the cover for hiding the lower surface of the fire extinguisher.

FIG. 1 is a perspective view seen from the ceiling showing the mounting state of members other than the fire extinguishing liquid tank, FIG. 2 is a perspective view seen from the ceiling showing the mounting state of members other than the cover, and FIG. 3 is a cover. It is a side view which shows the attachment state of members other than.
[0009]
1 is a ceiling board, 2 is an opening part which can insert a fire extinguishing liquid tank freely. The opening 2 is provided between two adjacent field edges 3. Reference numeral 4 denotes a bridge, which has horizontal plates 5 at both ends, a bottom surface 6 of a recess at the center, and the horizontal plate 5 has a bottom surface 6 of a recess parallel to the horizontal plate 5 via a vertical descent portion 8 that is substantially vertical. It is linked with. Two bridges 4 are used as a pair. A presser plate 7 rising vertically from the side surface of the bridge is extended to the outside of the pair of bridges 4. Therefore, as shown in FIG. 1, the presser plate 7 extends from the entire outer surface of the side end portion of the long bridge. The bridge 4 has the same width, but is preferably notched in an arc shape on the bottom surface 6 of the recess for the sake of accommodating a fire extinguishing liquid tank 20 having a circular cross section, which will be described later. The notch 9 reduces the distance between the bridge 4 and the fire extinguishing liquid tank and accommodates it in a compact manner.
[0010]
A hollow column 10 is vertically provided in close contact with the vertical descending portion 8 of the bridge 4 and the pressing plate 7. The hollow column 10 is bolted to the vertical descending portion 8 and the presser plate 7 at two surfaces perpendicular to each other, and the inclined surface has a hollow section vertical triangular column shape with both ends left. The opening of the triangular prism faces the center. The lower end of the hollow column 10 is the bottom surface 6 of the recess, and the upper end fixes a triangular plate. A perforation 11 is provided at the center of the triangular plate, a perforation is also provided in the bottom surface 6 of the recess directly below the perforation 11, and bolts are passed through the bottom surface 6 of the recess. The bolt head 12 is shown in FIG. Even if the bolt head 12 is rotated in this state, there is no moving member.
[0011]
A moving plate 13 having a shape capable of sliding on the inner periphery of the hollow column 10 is provided, and a nut (not shown) is provided on the moving plate 13 and screwed with a bolt. As a result, when the bolt head 12 is rotated, the moving plate slowly slides up and down. The hook receiving plate 14 is provided perpendicularly to the moving plate 13 and with an interval in which a hook portion of a hook-like engagement tool 16 to be described later enters. The hook receiving plate 14 needs to be longer than the hook portion of the hook-shaped engagement tool 16. Long rectangular protrusions 15 extend from both ends of the collar plate 14. Wider than hook-shaped engaging member 16 between both the angular projections 15, requiring engagement portion of the hook-shaped engaging member 16 is no possibility of length deviate by vibration. The collar receiving plate 14 is connected to the moving plate 13 via the connecting portion 17. That is, the movable plate 13, the connecting plate 17, the hook receiving plate 14, and the square protrusion 15 can be manufactured by cutting and bending a single steel plate, which are collectively referred to as the hook receiving engagement tool 18. .
[0012]
A pair of hook-like engagement tools 16 are provided at the farthest positions on the outer periphery of the fire extinguishing liquid tank 20. The hook-shaped engagement tool 16 supports and suspends the fire extinguishing liquid tank, and the tip is bent outward in a hook shape. In order for the hook-shaped engagement tool 16 to suspend the fire-extinguishing liquid tank more reliably, a steel plate belt is surrounded like a headband under the maximum diameter portion of the fire-extinguishing liquid tank, and the hook-shaped engagement tool is drawn from this belt. It is preferable to extend 16.
The hook at the tip of the hook-shaped engagement tool 16 is suspended from the hook receiving plate 14, and the tip of the hook does not reach the connecting portion 17. In this manner, the fire extinguishing liquid tank 20 is stably fixed to the saddle engagement tool 18 of the bridge 4 simply by placing the bridge on the field edge 3 and suspending the fire extinguishing liquid tank.
[0013]
The height of the fire extinguishing liquid tank 20 is adjusted by rotating the head 12 of the bolt. That is, by the rotation of the head portion 12 of the bolt, the hook receiving engagement tool 18 moves up and down while the hook-like engagement tool 16 is suspended, and the heavy fire extinguishing liquid tank moves up and down and can be installed at an optimum position. . Since the height adjustment by the bolt is performed from the lower surface of the ceiling, the operation becomes extremely easy. Alternatively, the height can be adjusted by providing a number of steps inside the hollow column 10 without using bolts, and inserting the movable plate 13 into the optimum step among the steps like a shelf. The horizontal position is adjusted by fine adjustment of the position of the bridge 4.
[0014]
The structure of the fire extinguisher in the present invention is such that a donut-shaped fire extinguishing liquid tank 20 is provided around a carbon dioxide gas cylinder 21 and filled with the fire extinguishing liquid. The abnormally high temperature detected by the sensor 22 projecting from the lower surface opens the carbon dioxide gas cylinder through various members below the carbon dioxide gas cylinder 21, and the fire extinguishing liquid filled in the fire extinguishing liquid tank 20 by the pressure of the carbon dioxide gas is removed from the lower surface. From the jet nozzle 23 protruding to As shown in FIG. 1 to FIG. 3, the lower surface of the fire extinguishing liquid tank 20 is covered with the opening 2 by the cover 24, but the sensor through hole 25 and the injection nozzle through hole 26 are formed at portions corresponding to the sensor 22 and the injection nozzle 23. Are respectively drilled. Reference numeral 30 denotes an upper floor structure.
[0015]
A male screw 27 is provided at the base of the sensor 22. Separately, a fixed fastening member 28 having a female screw threadedly engaged with the male screw 27 is provided, and the fixed fastening member head 29 has a larger diameter than the sensor through hole 25. At the same time, the sensor through hole 25 needs to have a diameter that allows the female screw portion of the fixed fastening member to freely pass therethrough.
[0016]
When attaching the automatic fire extinguisher to the ceiling, a belt 19 is wound below the maximum diameter portion of the fire extinguishing liquid tank 20, and the two hook-like engagement tools 16 are located farthest from each other with the hooks outward. Secure to. By attaching a steel or other metal belt, the hook-like engagement tool 16 can stably suspend the fire extinguishing liquid tank 20.
The fire extinguishing liquid tank 20 can pass through and an opening 2 narrower than the cover 24 is formed between the field edge 3 and the field edge of the ceiling. Next, two bridges 4 having one hollow column 10 are inserted from the opening 2, and the horizontal plate 5 is placed on the field edge 3 with the hollow column 10 facing up. At this time, the support plates 14 provided in the respective bridges 4 are set to face each other, and the hollow columnar bodies 10 are set to positions farthest from each other.
[0017]
A fire extinguisher is inserted from the opening 2, and the hook-shaped engagement tool 16 is suspended from the hook-receiving engagement tool 18. At this time, the position of the bridge 4 is appropriately adjusted so that it can be easily suspended. After the fire extinguisher is suspended, the bolt head 12 is rotated to adjust the height of the fire extinguisher. Thereafter, the fixing fastening member 28 is removed, and the cover 24 is covered so that the sensor 22 and the injection nozzle 23 protrude. Next, the fixed fastening member 28 is screwed into the male screw 27 on the upper part of the sensor through the cover from the outside of the cover 24. As the screwing progresses, the fixed fastening member head 29 has a diameter larger than that of the sensor through hole 25, and is thus coupled to the fire extinguisher to fix the cover to the ceiling plate. When the fire extinguisher is fixed to the ceiling board, the bridge 4 cannot be moved, and all the fixing members are stably fixed.
[0018]
The space behind the ceiling varies depending on the house and room, and in particular in apartments, it is often insufficient to accommodate the entire fire extinguisher. In this case, even if a fire extinguisher is inserted as far as it can enter the ceiling and the part that cannot be inserted is protruded, the appearance is extremely improved.
The hollow column 10 fixed to the bridge 4 is drawn long in the drawing. However, in the case of a low ceiling, it is preferable that the hollow column 10 be lower than the carbon dioxide cylinder 21 in a mounted state. In some cases, the fire extinguishing liquid tank 20 may protrude from the ceiling plate 1. In this case, if a deeper cover 24 is used, the fire extinguishing liquid tank 20 can be attached with an appearance that is not much different from the case where the entire case is stored.
[0019]
