It relates to the used fire engine (sometimes referred to as a fire engine, and also includes parts for a fire engine. The same shall apply hereinafter).
In particular, the present invention relates to a joining member for an aluminum block which is excellent in lightness, handleability, etc., and improves the mechanical strength of the aluminum block itself, and a fire engine using the same.

BACKGROUND ART Conventionally, various high-performance fire engines have been proposed from the viewpoint of increasing tank capacity and improving corrosion resistance and the like.
For example, a fire engine has been proposed that can run even on narrow alleys while maintaining or increasing the capacity of the water tank (see, for example, Patent Document 1).
More specifically, as shown in FIG. 9(a), in a fire engine having a cab 202, a chassis 203, and a water tank 204 mounted on the chassis 203, the water tank 204 is made of aluminum or an aluminum alloy. and the distance L2 between the cab 202 and the water tank 204 is 50% or less of the length L1 of the cab in the traveling direction of the fire engine.
Then, the water tank 204 has a partition plate made of aluminum or an aluminum alloy inside, and is further coated by spraying paint, coated with fluororesin, or formed with an anodized film, It is a fire engine that has undergone inner surface treatment.

In addition, although it is not a fire truck, in a truck tilting panel, in a panel formed by connecting a suitable number of hollow aluminum extruded materials, it penetrates inside from the mutual connection part of the hollow member, and enters the connection part with the end post. A tilting structure has been proposed to prevent intrusion of rainwater flowing along (see Patent Document 2, for example).
More specifically, as shown in FIG. 9(b), a track for fitting a U-shaped section 209 of an end post 210 having a U-shaped section 209 to the open end of the panel 208 in the longitudinal direction. It is Aori.

However, the fire truck of Patent Document 1 has a water tank made of aluminum or an aluminum alloy, thereby achieving weight reduction and increasing capacity, but there is still a problem that it is still insufficient.
In particular, the distance between the driver's cab and the water tank is limited to 50% or less of the length of the driver's cab in the direction of movement of the fire engine. It was difficult to contribute to
Furthermore, he proposed to manufacture a water tank from aluminum or an aluminum alloy, and further proposed a method of coating by spraying paint, coating with fluororesin, or forming an anodized film. From the point of view, it was inadequate and practically difficult to use.

In addition, the outer shape of the tilting of the truck of Patent Document 2 is practically only a rectangle, and it is possible to combine them horizontally and vertically to form a shelf (side box, etc.) of a predetermined shape. There was a problem that it could not be diverted to the side box of a fire engine because it could not be used.
In addition, the tilting of the truck in Patent Document 2 is intended to prevent rainwater from entering, and no consideration is given to the joining member for the aluminum block, which is lightweight and excellent in handleability, etc., and its application to fire trucks using it. I found a problem with no.

Therefore, the inventors of the present invention have made intensive studies and found that a fire engine using an aluminum block joint member having a predetermined structure and an aluminum block assembly derived from the aluminum block assembly can be made lighter and easier to handle.

It is a figure explaining the use condition of the joint member 10, and shall be referred to suitably.

1. Basic Configuration As shown in FIGS. 1(a) and 1(b), the basic configuration of the aluminum block joining member 10 is as follows: , is inserted and fixed via one joint member 31 (31a, 31b), and is fixed to another aluminum block 22 via another joint member 32 (32a, 32b).
That is, FIGS. 2(a) to 2(d) show a front view, a rear view, a plan view, and a right side view as typical examples of the aluminum block joining member 10. It has a side wall 11, a flat plate portion 13, and a second side wall 15, and has a generally U-shaped side surface.

As shown in FIG. 1(b), according to the aluminum block joining member 10, the plurality of aluminum blocks 21 and 22 are arranged at a predetermined angle, for example, in the vertical direction, without welding work or the like, and at a predetermined angle. Firmly fixing via a joint member 31 (hereinafter sometimes referred to as a first joint member 31) and another joint member 32 (hereinafter sometimes called a second joint member 32) can be done.
Further, according to the aluminum block joining member 10, for example, it is inserted into the predetermined space 21b formed by the partition plate 21a at the end of the aluminum block 21, and the aluminum block is fitted and joined. The mechanical strength of the ends of 21 can be significantly improved.

In addition, the material constituting the aluminum block joining member is not particularly limited as one of the basic constitutions, but normally it has good corrosion resistance, mechanical strength, etc., and is relatively lightweight and inexpensive. It is preferable that there is a sufficient number and that it is economically efficient.
Therefore, the materials of such aluminum block joint members are iron, aluminum, stainless steel, copper, nickel, titanium, tungsten, FRP (fiber reinforced plastic resin), CFRP (carbon fiber reinforced plastic resin), either alone or in combination of two or more. Combinations (including alloys) are preferred.

For example, if the constituent material is iron (including rust-prevented iron), it is preferable because it is less expensive, has high mechanical strength, and can be subjected to various rust-prevention treatments. It is one of the materials.
Moreover, if the constituent material is aluminum (including rust-proof treated aluminum), it is even lighter and cheaper, and furthermore, by applying alumite treatment, etc., corrosion resistance is improved, and the surface is smooth. It is one of the preferred materials because of its high flexibility and mechanical strength.
In addition, if the constituent material is stainless steel (SUS304, etc.), it is one of the preferred materials because it has good corrosion resistance, mechanical strength, etc. even as it is, and is also excellent in surface smoothness, etc. be.
Furthermore, if the constituent material is FRP derived from a predetermined resin composition containing a predetermined amount (for example, 20 to 80% by weight relative to the total amount of 100% by weight) of glass fiber, carbon fiber, etc. It is one of the preferred materials because it has good corrosion resistance, mechanical strength, etc., and is also excellent in terms of lightness, moldability, etc.

In addition, in order to further improve the corrosion resistance, the surfaces of the aluminum block joining members made of various materials are subjected to known rust prevention treatments such as zinc phosphate plating, alumite treatment, chromate treatment, and silicification flame treatment. It is also preferable to apply at least one of treatment, application of antirust paint, and the like.

However, such an aluminum block joining member 10 has, as a basic configuration, configurations (A) to (D) described later, and a predetermined aluminum block 21 is firmly fixed to another aluminum block 22 or the like. Various modifications are possible as long as they can be reinforced.
For example, although not shown, in place of another aluminum block 22 to be joined to one aluminum block 21 by the aluminum block joining member 10, a metal plate as a different member derived from a different material can be used according to various uses and aspects. , a resin plate, a ceramic plate, a resin sheet, and a multi-layer sheet of a combination thereof.
The aluminum block joining member 10 shown in FIG. 1(a) has a first side wall 11, a flat plate portion 13, and a second side wall 15 with a pair of cuts 17 serving as a configuration (B), which will be described later, as a boundary. It consists of three blocks, the first block, the second block, and the third block, which are equal-width members, including the It may be configured from

Furthermore, the three blocks including the first side wall 11, the flat plate portion 13, and the second side wall 15 do not necessarily have to exist on the same plane, and two of the three blocks, the left and right The blocks may also be bent upwards or downwards respectively.
In this way, when the three blocks are not on the same plane, on the premise that the end of the aluminum block is also correspondingly formed into a semicircle or an inverted semicircle, when joining aluminum blocks having a predetermined curved surface Also, a joining member for an aluminum block can be used.
Therefore, even a structure having a curved surface, such as a shelf, can be easily formed.

2. Configuration (A)
Configuration (A), as shown in FIGS. 1(a) and 2(d), is a configuration relating to the outer shape of the aluminum block joining member 10, and includes a first side wall 11, a flat plate portion 13, and a second and a side wall 15 having a U-shaped side surface.
That is, if the side surface shape, which is a shape that can be seen when the aluminum block joining member is viewed from the side, is roughly U-shaped, the plurality of predetermined spaces formed by the partition plates at the ends of the aluminum block can be easily inserted.
Then, by using a predetermined joining member (for example, a first joining member and a second joining member) for the insertion portion of the aluminum block joining member and the through hole formed therein, the aluminum block itself, or It can be easily and firmly fixed to a predetermined place in another aluminum block.

Further, the height of the first side wall of the aluminum block joint member can be changed depending on the form and application of the aluminum block, but it is usually preferable to set the value within the range of 0.5 to 5 cm.
Similarly, the length of the first side wall is preferably within the range of 8 to 25 cm, although it depends on the form and application of the aluminum block.
Furthermore, similarly, the thickness of the first side wall is preferably in the range of 0.1 to 5 mm, although it depends on the form and application of the aluminum block.
The height, thickness, etc., of the first side wall are preferably the same as the height, thickness, etc., of the second side wall, which will be described later. , the height, thickness, etc. of the second side walls are also preferably different.

In addition, the thickness of the flat plate portion of the aluminum block joining member can be appropriately changed depending on the aspect and application of the aluminum block, but it is usually preferable to set the thickness within the range of 0.1 to 5 mm.
Similarly, the length of the flat plate portion of the joining member for aluminum block is usually set to a value within the range of 8 to 25 cm, although it depends on the aspect and application of the aluminum block. It is preferably substantially equal to the length.

Also, the height of the second side wall of the aluminum block joining member can be appropriately changed depending on the form and application of the aluminum block, but it is usually preferably within the range of 0.5 to 5 cm.
Similarly, the length of the second side wall is preferably within the range of 8 to 25 cm, although it depends on the form and application of the aluminum block.
Furthermore, similarly, the thickness of the second side wall is preferably within the range of 0.1 to 5 mm, although it depends on the form and application of the aluminum block.
The height, thickness, etc., of the second side wall are preferably the same as the height, thickness, etc., of the first side wall described above. , the height and thickness of the first side wall are preferably different.

However, although the first side wall and the second side wall may stand vertically with respect to the flat plate portion, the aluminum block joining member is formed by a partition plate at the end of the aluminum block. It is also preferable to be able to easily insert and fit into the space.
That is, it is also preferable that the angle formed by the first side wall and the second side wall, which are originally in a parallel relationship with respect to the insertion direction, becomes narrower toward the distal end, and forms a so-called tapered shape with the flat plate portion interposed therebetween.
More specifically, the angles formed by the first side wall, the second side wall, and a plane assumed to be perpendicular to the flat plate portion are each set to a value within the range of 0.1 to 10°. is preferred, a value within the range of 1 to 8° is more preferred, and a value within the range of 2 to 5° is even more preferred.

3. Configuration (B)
Configuration (B) relates to the notch 17 provided in the aluminum block joining member 10, as shown in FIG. 1(a).
A pair of partition plates 21a at the ends of one aluminum block 21 (hereinafter sometimes referred to as the first aluminum block 21) are inserted into the first side wall 11 and the second side wall 15, respectively. At least one notch 17 is provided.
That is, per unit length (for example, about 30 cm) of the first aluminum block 21 in the horizontal direction, an equal distance from each end of the first side wall 11 and the second side wall 15 of the aluminum block joining member 10 is measured. are provided in pairs at positions.
Accordingly, a notch 17 is provided at a predetermined position of the aluminum block joining member 10 so that the partition plate 21a at the end of the first aluminum block 21 can be inserted vertically and fitted therewith. preferable.

In addition, the number of cuts in the aluminum block joining member is usually 2 to 10, depending on the length of the aluminum block joining member and the application and length of the aluminum block to be inserted. A value within the range is preferred.
The reason for this is that if the number of cuts is less than 2, even if the aluminum block or the partition plate is produced with slightly inferior accuracy, it can be easily inserted, but the gap between the aluminum block joining member and the first aluminum block cannot be easily inserted. This is because there may be a problem that the joint between the two tends to become fragile.
On the other hand, when the number of cuts exceeds 10, although the joint between the aluminum block joint member and the first aluminum block tends to be strong, the production accuracy of the aluminum block and the aluminum block joint member is deteriorated. This is because there may be a problem in that positional deviation occurs, and the two cannot be easily inserted and fitted together.
Therefore, it is more preferable to set the number of cuts in the aluminum block joining member to a value within the range of 4 to 6 (2 to 3 pairs of cuts).

The width of the cut in the aluminum block joining member corresponds to the distance between adjacent first side walls or between opposing and adjacent second side walls, and is usually in the range of 1 to 10 mm. is more preferable.
The reason for this is that when the width of the cut is less than 1 mm, the joint between the aluminum block joint member and the first aluminum block tends to be strong, but the production accuracy of the aluminum block and the aluminum block joint member is inferior. , and it may not be possible to easily insert both.
On the other hand, if the width of the cut exceeds 10 mm, the aluminum block can be easily inserted even if the production accuracy of the aluminum block is somewhat inferior, but the joint between the aluminum block joint member and the first aluminum block becomes weak. This is because there may be a problem that it is easy to
Therefore, it is more preferable to set the width of the cut in the joining member for aluminum blocks to a value within the range of 0.5 to 8 mm, more preferably to a value within the range of 1 to 5 mm.

The width of the cut means the average value of the width in the direction of the cut, and the width near the flat portion and the width on the opposite side may be substantially the same or different.
For example, if the width near the flat plate portion is narrower than the width near the opposite side, it will take some time and a strong insertion force to insert the aluminum block into the partition plate. After being inserted, it can be easily prevented from coming off from the partition plate.
On the other hand, if the width of the cut is wider in the vicinity of the flat plate portion than in the vicinity of the opposite side, it can be said that the partition plate of the aluminum block can be easily inserted and the handleability is further improved. Furthermore, if an adhesive, a wedge, or the like is applied to the gap between the aluminum block partition plate and the aluminum block joining member, it is possible to more easily prevent the aluminum block from coming off the partition plate.

In addition, when the aluminum block joining member of the configuration (A) is viewed as a long piece, it is preferable to provide cuts at positions that are equally divided into 2 to 10 portions in the length direction.
The reason for this is that if the positions of the cuts are not evenly spaced and less than two halves are formed, the left-right balance of the aluminum block joining member will be poor.
Therefore, there may arise a problem that the joint between the aluminum block joint member and the first aluminum block tends to become weak.
On the other hand, if the cuts are provided at positions exceeding 10 equal parts in the length direction, there may be a problem that when the production accuracy of the aluminum block and the joining member for the aluminum block is inferior, the two cannot be easily inserted. Because there is
Therefore, it is more preferable to set the cutting position of the joining member for aluminum block to a position that is equally divided into 3 to 6 parts in the length direction.

In addition, the shape of the cut formed in the joint member for the aluminum block depends on the use, length, etc. of the aluminum block, but it is usually linear, rectangular, S-shaped, tapered (funnel-shaped), etc. preferable.
The reason for this is that with such a shape of the cut, while the formation itself is easy, it is relatively easy to insert into the aluminum block, and once it is inserted, it is difficult to detach. .

4. Configuration (C)
Configuration (C) is, as shown in FIG. It is a configuration for fixing the aluminum block joining member 10 to the first aluminum block 21 by using the joining member (first joining member) 31 of .
That is, as shown in FIGS. 1(a) and 1(b), a pair of first through holes 18 are provided at respective paired positions of the first side wall 11 and the second side wall 15, and the pair of A pair of through-holes 18a previously provided in the first aluminum block 21 corresponding to the first through-holes 18 of .
Then, a bolt 31a as a threaded bolt is inserted as a first joint member so as to pass through four holes including a pair of two first through holes 18 in the aluminum block joint member 10. are firmly screwed together by nuts 31b or nuts with washers from both sides and fixed.

Also, the number of the pair of first through-holes depends on the application and length of the first aluminum block, but is usually in the range of 2 to 10 per unit length (about 2 cm) of the aluminum block. A value within is preferred.
The reason for this is that if the number of such first through-holes is less than two, the aluminum block joint member can be inserted relatively easily and in a short period of time even if the aluminum block production accuracy is somewhat inferior, but the aluminum block This is because there may be a problem that the joint between the joint member for the first aluminum block and the first aluminum block tends to be weak.
On the other hand, when the number of such first through-holes exceeds 10, the number of first joining members to be used also increases, so that the joint between the aluminum block joining member and the first aluminum block is firmly joined. However, the manufacturing accuracy of the aluminum block and the joint member for the aluminum block is inferior, and positional deviation occurs, which may cause a problem that the first joint member itself cannot be easily inserted.
Therefore, it is more preferable to set the number of first through holes in the aluminum block joining member to a value within the range of 4 to 6 (the number of pairs of first through holes is 2 to 3).

The diameter (equivalent circle diameter) of the first through hole is usually in the range of 1 to 8 mm, although it depends on the use and length of the first aluminum block, or the thickness of the first joining member. A value within is preferred.
The reason for this is that if the diameter of the first through-hole is less than 1 mm, the aluminum block or the joining member for the aluminum block is produced with poor precision, causing misalignment, and the first joining member itself cannot be easily inserted. This is because a problem may occur.
On the other hand, if the diameter of the first through-hole exceeds 8 mm, the first joining member can be inserted relatively easily and in a short time even if the aluminum block is produced with slightly inferior accuracy. This is because if bolts and nuts with relatively small diameters are used, the problem may occur that the joint between the aluminum block joint member and the first aluminum block tends to be weak. .
Therefore, it is more preferable to set the diameter (equivalent circle diameter) of the first through-hole to a value within the range of 1.5 to 7 mm, further preferably within the range of 2 to 6 mm.

The interval between the adjacent first through-holes can be appropriately changed depending on the purpose, length, size, etc. of the first aluminum block, but it is usually set to a value within the range of 0.5 to 10 cm. is preferred.
The reason for this is that if the distance between the adjacent first through holes is less than 0.5 cm, the aluminum block or the joining member for the aluminum block is produced with poor accuracy, resulting in misalignment and causing the first joining member itself to be displaced. This is because there may be a problem that it cannot be easily inserted. Moreover, since the distance between adjacent first through-holes is relatively small, the adjacent joining members may interfere with each other, which may cause a problem that they cannot be easily inserted.
On the other hand, if the interval between the adjacent first through holes exceeds 10 cm, the first joint member can be inserted relatively easily and in a short time even if the aluminum block production accuracy is somewhat inferior, but the aluminum block This is because there may be a problem that the joint between the joint member and the first aluminum block tends to be weak.
Therefore, it is more preferable that the distance between the adjacent first through-holes is equal and the value is within the range of 2 to 8 cm, and more preferably within the range of 3 to 6 cm.

Also, the type of the first joint member is not particularly limited, but a predetermined joint member (first joint member) is passed through the first aluminum block and firmly held at a predetermined position. Anything to fix it is fine.
Therefore, as such a first joining member, a combination of a bolt 31a and a nut 31b, as shown in FIG. Alternatively, it is preferably a rivet.

5. Configuration (D)
Configuration (D), as shown in FIG. , each through a predetermined joint member (second joint member) 32 and firmly fixed to another aluminum block 22 (hereinafter sometimes referred to as a second aluminum block 22). 2 through hole 19. FIG.

Further, the number of second through-holes depends on the length of the aluminum block joining member, further the application and length of the second aluminum block, but is usually in the range of 1 to 8. It is preferable to
The reason for this is that the aluminum block joining member and the second aluminum block cannot be joined unless the number of such second through holes is one or more.
On the other hand, if the number of such second through-holes exceeds eight, the number of joining members to be used also increases, so although the joint between the aluminum block joining member and the second aluminum block tends to be strong. This is because there are cases where the handleability of the joining member for the aluminum block is lowered, and there are cases where the joining becomes difficult due to misalignment. That is, the length of the aluminum block joint member (the length of the first and second side walls and the length of the flat plate portion) is substantially increased according to the number of the second through holes. This is because the size becomes large and the handleability may deteriorate. Further, when the number of the second through holes increases due to the manufacturing accuracy of the second aluminum block and the joining member for the aluminum block, misalignment occurs between the corresponding through holes in the second aluminum block. This is because it may become difficult to bond between the aluminum block bonding member and the second aluminum block.
Therefore, it is more preferable to set the number of second through holes in the aluminum block joining member to a value within the range of 2 to 4.

In addition, the diameter of the second through-hole (equivalent circle diameter) is equal to or larger than the diameter of the first through-hole (equivalent circle diameter), and the application and length of the second aluminum block, Alternatively, although it depends on the thickness of the second joining member, etc., it is usually preferable to set the value within the range of 3 to 15 mm.
The reason for this is that if the diameter of the second through-hole is less than 3 mm, the diameter of the one-sided bolt as the second joint member becomes excessively small, and the gap between the aluminum block joint member and the second aluminum block becomes excessively small. This is because there may be a problem that the joint between the two tends to become fragile.
On the other hand, if the diameter of the second through-hole exceeds 15 mm, the aluminum block and the joining member for the aluminum block are produced with poor accuracy, resulting in misalignment and the problem that the second joining member itself cannot be easily inserted. This is because
Therefore, it is more preferable to set the diameter (equivalent circle diameter) of the second through-hole to a value within the range of 4 to 12 mm, and even more preferably to a value within the range of 5 to 10 mm.

The interval between adjacent second through-holes can be appropriately changed depending on the use, length, etc. of the second aluminum block, but it is usually preferable to set it to a value within the range of 5 to 20 cm.
The reason for this is that if the interval between the adjacent second through-holes is less than 5 cm, the production accuracy of the aluminum block and the joining member for the aluminum block is deteriorated, resulting in misalignment and making the second joining member itself difficult to remove. This is because there may be a problem that it cannot be inserted.
On the other hand, if the interval between the adjacent second through-holes exceeds 20 cm, the second joint member can be inserted relatively easily and in a short time even if the aluminum block production accuracy is somewhat inferior, but the aluminum block This is because there may arise a problem that the joint between the joint member and the second aluminum block tends to be weak.
Therefore, it is more preferable to set the interval between adjacent second through holes to a value within the range of 6 to 15 cm, and more preferably to a value within the range of 7 to 10 cm.

Also, the type of the second joint member is not particularly limited, provided that it is for fixing a predetermined joint member (second joint member) through the second aluminum block. good.
Therefore, as such a second joining member, it is usually preferable to use a one-sided bolt 32a including a flanged hollow member 32b, as shown in FIG. 3(b).
Since the second joint member includes the flanged hollow member in this way, damage to the first side wall and the second side wall, or the second through hole in the second aluminum block, loosening, etc. can be prevented. This is because it can be effectively prevented. Furthermore, the second aluminum block can be attached to the first aluminum block by combining the second aluminum block connecting member with the chimney-shaped second through hole which has an internal thread and functions as a nut. , can be firmly and easily joined.

In addition, it is preferable to relate the configuration (D) to the configuration (C) described above.
That is, assuming a first extension line passing through the first through hole for the configuration (C) and a second extension line passing through the second through hole for the configuration (D), the aluminum block joining member The first through-hole and the second through-hole are arranged such that the first extension line and the second extension line intersect in the vertical direction when viewed from the side of the end of the is preferred.
The reason for this is that, in the aluminum block joining member, the first through-hole and the second through-hole intersect substantially in the vertical direction, so that the first aluminum block and the second through-hole aluminum blocks can be appropriately combined so as to be arranged in the horizontal direction or the vertical direction.
In addition, if necessary, the angle at which the first extension line and the second extension line intersect can be appropriately changed in relation to the first through hole and the second through hole, for example, 30 It is also possible to join the first aluminum block and the second aluminum block at different angles if they intersect in the direction of ~120°.

6. Form of the first aluminum block The form of the first aluminum block is not particularly limited as long as it is a panel formed by connecting an appropriate number of hollow aluminum extruded members, but the length direction It is preferable that the cross-sectional shape when cut is a rectangular shape composed of a plurality of partition plates and the space formed by them.
More specifically, as shown in FIG. 5(a), the first aluminum block 21 is an aluminum block molded product having a rectangular space divided equally by four partition plates 21a. , three predetermined spaces 21b.
Then, as shown in FIG. 5(a), the side ends of the first aluminum block 21, that is, the left and right sides of the three predetermined spaces 21b are fitted with another aluminum block molded product 21' to face each other. It is preferable to have protrusion connecting portions 21c and 21e for engaging and connecting protrusions having a generally triangular cross-section.

Further, the length and thickness of the first aluminum block may be appropriately changed depending on the application, etc., but normally, the length indicated by L1 in FIG. , more preferably in the range of 25 to 45 cm, and even more preferably in the range of 30 to 40 cm.
Also, the thickness of the first aluminum block indicated by W1 in FIG. is more preferable, and a value within the range of 3 to 6 cm is even more preferable.

In addition, as shown in FIG. 5(b), a plurality of the first aluminum blocks shown in FIG. Blocks are also preferred.
In the example shown in FIG. 5(b), two first aluminum blocks having a width indicated by L1 are connected in the horizontal direction using a predetermined connecting portion (male-female protrusion), generally indicated by L1×2. It is configured as a large-sized first aluminum block having a width (L2) that is equal to the width (L2).

7. 2. Change of Aluminum Block Joining Member Further, the aluminum block joining member is partially changed, and as shown in FIGS. It is also preferable to combine the block joint member and the second aluminum block joint member.
That is, as shown in FIG. It is preferable to prepare another aluminum block joining member 10a having an opening there, and to form a nested structure in which both are in contact with each other and face in the same direction.
By adopting the nested structure facing the same direction in this way, the fitability with the aluminum block is improved, and the mechanical strength of the aluminum block can be further improved.
Moreover, one aluminum block joining member 10 and another aluminum block joining member 10a can be made of different materials. For example, one aluminum block joint member 10 is made of zinc phosphate treated iron, and another aluminum block joint member 10a is made of glass fiber-containing epoxy resin. Can be nested.

Also, as shown in FIG. It is also preferable to prepare another aluminum block joining member 10b having an opening there, and to form a nested structure in which both members face each other.
By adopting a nested structure in the facing direction in this way, not only is the fitting between the aluminum block improved, but also the mechanical strength of the aluminum block joining member itself and the aluminum block into which it is inserted is improved. further improvement can be achieved.
Furthermore, in the nested structure shown in FIG. 2(f), as in the nested structure shown in FIG. 2(e), one aluminum block joint member 10 and another aluminum block joint member 10b Constructed from different materials, nested structures can be more precise and easier to assemble.
In any case, if it is a combination type aluminum block joining member with a nested structure, it is fixed to the first aluminum block and the second aluminum block more firmly and without a gap. It is possible to

8. Reinforcement member Further, as shown in FIGS. 4(a) to 4(c), an aluminum block formed by joining a first aluminum block and a second aluminum block via an aluminum block joining member 10. In order to strengthen the bonding strength of the assembly 20, a reinforcing member 33 having an L-shaped side surface (including a substantially L-shaped configuration; the same shall apply hereinafter) is further provided. is preferred.
The reason for this is that if the aluminum block assembly 20 is further provided with such a reinforcing member 33, the mechanical strength (mechanical stability) in the horizontal and vertical directions is maintained while maintaining the characteristics of weight reduction and miniaturization. This is because it is possible to further enhance the
Moreover, depending on the type of joining member, the reinforcing member 33 can be attached later, so it can be easily provided.

More specifically, as shown in FIG. 4( a ), if the side surface shape of the reinforcing member 33 is L-shaped, which is the shape that can be seen when the reinforcing member 33 is viewed from the side, the aluminum block joining member 10 Since it is in contact with both the first aluminum block and the second aluminum block which are joined in the horizontal direction or the vertical direction with no gap, it can be attached easily and firmly.
In addition, when the first aluminum block and the second aluminum block are joined at different angles (for example, 30 to 120 ° direction), the side shape of the reinforcing member is configured according to the angle. It is also possible to change the side shape so that the angle formed by the two sides forming is 90° (L-shaped), for example, 30 to 120°.

Further, the length of the reinforcing member is preferably within the range of 10 to 30 cm, although it depends on the aspect and application of the aluminum block connecting member and the aluminum block.
Furthermore, the thickness of the reinforcing member is preferably within the range of 0.5 to 5 mm, although it depends on the aspect and application of the aluminum block joining member and the aluminum block.

In addition, although the material constituting the reinforcing member is not particularly limited, it usually has good corrosion resistance, mechanical strength, etc., is relatively lightweight, is inexpensive, and is economical. Excellent is preferred. Therefore, it is possible to use the same material as that of the aluminum block joining member described above. For example, stainless steel can be used as the material for the reinforcing member.

Here, the method of attaching the reinforcing member 33 is not particularly limited, but as shown in FIG. It is preferable to attach them at the same time.
The reason for this is that by attaching in this way, the through holes 33a in the reinforcing member 33, the first through holes 18 in the aluminum block joining member 10, and the through holes 18a in the first aluminum block 21 are positioned. This is because a combination of the bolt 31a and the nut 31b as the first joining member or a predetermined rivet can be used to firmly fix them.
As an example, as shown in FIG. 4C, in an aluminum block assembly 20, an aluminum block joint member 10, a first aluminum block 21, and a reinforcing member 33 are used as first joint members. Further, the reinforcing member 33 and the second aluminum block are fixed by a predetermined rivet 31c as the third joint member 34. As shown in FIG.

9. Method of use As shown in FIGS. A typical example will be described along the following steps (1) to (4).

(3) Fire extinguishing fluid storage tank chamber The configuration of the fire extinguishing fluid storage tank chamber 54 shown as part D in the fire engine 100 of FIG. Although not particularly limited, it is usually preferable to use a polypropylene resin tank or a stainless steel tank because of their good corrosion resistance and light weight.
In particular, a polypropylene resin tank is preferable because it is lightweight, moldable, and translucent, can be welded, and can be made to any size.
A tank made of stainless steel such as SUS304 is preferable because it is excellent in corrosion resistance and mechanical properties and is relatively inexpensive.
Then, as shown in FIGS. 7(b) to 7(e), it is preferable to cover the periphery of the fire extinguishing liquid storage tank chamber 54, which is particularly susceptible to corrosion, with a multi-layer structure 40. FIG.

4. Side Box (1) Basic Configuration The basic configuration of the side boxes 60 and 61 (hereinafter sometimes referred to as fitting plates) in FIG. For an aluminum block inserted and fixed via one joint member 31 to the partition plate 21a at the end of the block 21, and to be joined to another aluminum block 22 or the like via another joint member 32 A plate-like object and an aluminum block assembly 20 using the joining member 10. FIG.
More specifically, as shown in FIGS. 1(b) to (c) and FIGS. 5(a) to (b), in one aluminum block 21, a plurality of The plate-like object and aluminum block assembly 20 is formed by inserting and fixing the joint member 10 for the aluminum block so as to straddle the predetermined space 21b of the plate-like object and the aluminum block 20, and further connecting with another aluminum block 22 or the like.
Further, as described in the first embodiment, the aluminum block joint member is characterized by having the configurations (A) to (D), and the assembly structure thereof.
Therefore, as shown in FIGS. 8(a) to 8(d), it is preferable that the side boxes 60 and 61 have a shelf structure with a predetermined structure as a basic structure.

(2) Shelf structure The predetermined shelf structure that constitutes the side boxes 60 and 61 is, as shown in FIGS. , or on both sides.
In such a shelf structure, it is preferable to have a hose chamber for accommodating a hose having a length of 5 to 30 m and a reel thereof.
Therefore, although it depends on the type and mode of the fire engine, when the shelf structure that constitutes the side box is viewed from the side, it is preferable that it is generally gate-shaped. It is preferable to form a predetermined space and use it as a hose chamber to accommodate the hose and its reel.
In addition, in the shelf structure, a part of the instrument panel and folding stairs for the operator to go up and down are provided in order to take out the equipment in the high position and to operate the instrument panel easily. is preferred.
Furthermore, in the shelf structure, it is preferable to provide a space for storing equipment such as a cutter device for removing obstacles in fire extinguishing work, a generator, a simple fire extinguisher, and the like.
In addition, since the predetermined shelf structure that constitutes the side box described above basically has no welding points, it is said that it is easy to assemble, change, disassemble and repair, etc., so as to obtain a desired form. Characteristic.

(3) Shutter Although not shown, it is preferable to provide a predetermined shutter to prevent hoses and other fixtures stored in the shelf structure constituting the side box from falling and to prevent tampering from the outside.

(4) Ladder Also, as shown in FIG. 6, it is preferable to provide a ladder 128 having a predetermined length and a telescopic mechanism on the ceiling portion of the fire engine 100, that is, on the upper part of the side box or the like. .
Therefore, by using such a ladder, fire-fighting work and rescue work at high places can be carried out efficiently.
The length of the ladder when folded is usually about 3 to 5 m, but it is preferable that the length is about 8 to 20 m when extended.

5. Multilayer structure 1
Further, it is preferable to provide a multi-layer structure (also referred to as a multi-layer lightweight panel) 40 derived from aluminum plate 41/resin sheet 42/aluminum plate 43 as shown in FIG.
More specifically, at least the ceiling portion in contact with the fire extinguishing fluid storage tank chamber 54 in the housing 50 as shown in FIG. 7(b), the fire extinguishing fluid storage tank in the housing 50 as shown in FIG. A partition 52a between the chamber 54 and the pump chamber 53; ), it is preferable to use the multi-layer structure 40 for the partition wall 52c between the fire extinguishing fluid storage tank chamber 54 and the side boxes 60, 61 in the housing 50, respectively.
The reason for this is that by using a predetermined multi-layer structure around the fire extinguishing fluid storage tank chamber 54, which is susceptible to corrosion, the light weight, corrosion resistance, and ease of assembly of the fire engine as a whole can be achieved. This is because it can be made into a more excellent mode with respect to etc., and in addition, it can be easily repaired in a fire engine, disassembled and discarded.

In addition, the constituent materials of the resin sheet include polystyrene resin, foamed urethane resin, foamed phenolic resin, hard urethane, rubber sheet, carbon fiber-containing resin sheet, aramid fiber-containing resin sheet, glass fiber-containing resin sheet, and foamed resin-containing resin sheet. , lightweight inorganic fiber-filled foam sheet, lightweight organic fiber-filled foam sheet, and the like.
In particular, expanded polystyrene resin can be said to be a suitable constituent material for the resin sheet from the viewpoints of versatility, lightness, economy, heat insulation, durability, handleability, and the like.
Furthermore, an organic noncombustible material or an inorganic noncombustible material alone or a mixture thereof is usually blended in a range of 0.1 to 10% by weight with respect to the total amount of the resin sheet as part of the constituent materials of the resin sheet. is also preferred.

Further, regarding the form of the multilayer structure 40 shown in FIG. 3(c), at least one of the outer surfaces of the aluminum plates 41 and 43 existing on the front and back sides is subjected to a known rust prevention treatment such as , zinc phosphate treatment, alumite treatment, chromate treatment, silicicification flame treatment, or coating treatment with an anticorrosive coating.
The thicknesses of the aluminum plates 41 and 43 may be the same or different, but it is generally preferable that the thickness of each is in the range of 0.5 to 15 mm, preferably 1 to 10 mm. is more preferably a value within the range of 2 to 5 mm.
In addition, the thickness of the resin sheet 42 in the multilayer structure 40 is usually preferably set to a value within the range of 1 to 30 mm, more preferably set to a value within the range of 5 to 25 mm, and more preferably 8 to 20 mm. It is more preferable to set the value within the range of
The mass per unit area of such a multilayer structure is generally preferably within the range of 0.5 to 20 kg/m ² , more preferably within the range of 3 to 10 kg/m ² . more preferred.

Furthermore, with respect to the form of the multilayer structure 40 shown in FIG. 3(c), the end portion (cross section) of the multilayer structure 40 is subjected to a coating treatment (protection treatment) to form a protective film having a thickness of, for example, 10 to 3000 μm. 44 is preferably formed, and the thickness thereof is more preferably 100 to 2000 μm, even more preferably 300 to 1000 μm.
The reason for this is that thinner is sprayed onto the housing 50 (see FIG. 7) including the multilayer structure 40 as a pretreatment in the painting process in the manufacture of the fire engine. This is because the thinner can prevent the resin sheet 42 in the multilayer structure 40 from dissolving. Furthermore, it is possible to suppress the water absorption of the resin sheet 42 and improve the durability while maintaining the lightness of the multilayer structure 40 .
The coating material (protective material) used in such coating treatment is not particularly limited as long as it does not affect the properties of the multilayer structure 40 and can prevent dissolution by thinner. Commercially available coating materials include, for example, a two-liquid room temperature curing type epoxy adhesive (manufactured by 3M, product name “Automix (trademark) Panel Bond 8115”) and the like.

6. Multilayer structure 2
A method for attaching the multilayer structure 40 will be described with reference to FIG. 3(d).
That is, typically, a predetermined frame-shaped hole is provided in a part of the frame or wall that constitutes the housing 50, and the multilayer structure 40 is fitted therein, and predetermined rivets 45 are used to secure the housing. It is preferably fixed firmly and lightly to the body.
Moreover, when the fixing location is viewed from the lateral direction, the adjacent rivets do not overlap in the vertical direction. ) is preferably fixed to the housing.
Further, when fixing the multilayer structure to the housing using a predetermined rivet, the rivet should penetrate the housing and the aluminum plate and reach a part of the resin sheet. is preferred.
Furthermore, when used as a partition wall between a storage tank chamber and a side box, a predetermined multilayer structure is formed on the surface of the wall of the housing, whether or not a frame is used. Rivets can be used to fasten easily and quickly.
Therefore, there is no need to provide a predetermined hole for fixing the connecting jig in the housing as an adherend made of, for example, zinc phosphate-treated iron, and furthermore, corrosion resistance and mountability are improved.

7. Total weight As illustrated in FIG. 7, at least the ceiling of the housing 50, the front and rear of the housing 50, the partition wall between the fire extinguishing fluid storage tank chamber 54 and the side boxes 60, 61, etc. In addition, by attaching the multilayer structure 40 for reinforcement, the strength of the housing 50 and the amount of constituent materials used can be reduced accordingly.
