Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a reinforcing material used to maintain the intersection angle of two intersecting walls in a container such as a tank.

The larger the capacity of a liquid storage container such as a tank, the more likely its side wall will bend outward when it is filled with liquid.

Therefore, large-capacity tanks had to be reinforced to prevent the side walls from bending.

In order to meet this need, one of the methods commonly used in the past was to insert a metal rod called a stay bolt with threads on both ends between the opposing side walls, and connect the threads to the side walls. This method keeps the distance between the side walls constant.

However, in large-capacity tanks, the distance between the side walls is large, so the metal rod that is passed between the side walls becomes long, and the metal rod itself has the disadvantage of being significantly bent.

Therefore, as an alternative method, a shaped steel such as an angle or a channel is inserted diagonally between two walls that intersect with each other, and both ends of the shaped steel are bent to form a bent piece parallel to the wall surface. It was proposed to fix the pieces to the wall with bolts (1986)
-85412).

Although this method was able to achieve the purpose of reinforcement,
In order to form a bent piece parallel to the wall surface, it was necessary to cut out the unnecessary part of the steel section and bend the remaining part using a special machine, so the disadvantage was that it took a lot of work. .

This inventor proposed that in the above method, by using a metal rod called the aforementioned stay bolt instead of the shaped steel, and fixing the tsuba instead of creating a new piece parallel to the wall surface, the trouble of notching or bending the shaped steel could be avoided. I realized that I didn't need it.

Also, metal rods are easier to bend than shaped steel, so
I have found that it is convenient to bend both ends of the metal rod at right angles to the wall surface and position the collar at the bent portions, since the threaded portions at both ends serve as bolts.

However, when a metal rod is bent, there is a slight roundness at the bend, so the metal rod bends with a roundness near the wall surface, and the rounded part acts as a spring and allows the side wall to flex. I understand.

Therefore, the inventor attempted to cover the folded portion with the thickness of the tsuba.

As a result, it was found that by doing so, the roundness of the bent portion could be prevented from acting as a spring.

This idea was made based on such ideas and knowledge.

That is, in this invention, both ends of the metal rod in the longitudinal direction are bent to the same side, the bent portion is covered with a flange, each of the bent pieces is made to stand upright to the flange surface, and a screw is provided on the outer peripheral surface of the bent piece. , is a reinforcement material.

The reinforcing material according to this invention will be explained as follows based on the drawings.

FIG. 1 is a partially cutaway side view showing an example of the reinforcing material according to this invention.

2 to 6 are partially cutaway perspective views showing how the reinforcing material according to this invention is used.

In FIG. 1, both longitudinal ends of a metal rod 1 are bent to the same side.

Bending portion 11. That is, the flange 2 is attached to the base of the piece produced by bending, and the entire curvature portion is covered by the thickness of the flange 2.

All of the bent pieces 12 stand upright with respect to the collar surface 21.

Here, the flange surface 21 is the surface of the flange facing toward the end of the metal rod 1.

A screw is provided on the outer peripheral surface of the bent piece 12.

This structure is the reinforcing material a according to this invention.
It is.

In the above reinforcing material a, an iron rod or a stainless steel rod is generally used as the metal rod 1.

The cross section of the metal rod 1 may be either round or square (for example, hexagonal).

Moreover, the metal rod 1 may be hollow.

The thickness of the metal rod 1 varies depending on the length between the brim, but generally about 12 mm is appropriate.

Note that the metal rod 1 can be joined in the middle, for example, by welding.

When joining, the intermediate portion may be a strip or an angle.

The bending angles at both ends of the metal rod 1 are preferably the same, but may be different.

The collar 2 is suitably circular or polygonal.

In the case of a circular shape, it is desirable that the diameter is about 5Qmm.

Further, it is desirable that the tsuba 2 be made of iron or stainless steel.

Welding is suitable for fixing the collar 2 to the metal rod 1.

In the case of welding, when the bent portion of the metal rod 1 is covered with a flange, the flange includes the metal layer used for welding.

As the flange 2, not only one having a constant thickness such as a plate shape but also one having a raised conical shape at the center can be used.

In this case, it is desirable that the bottom of the cone be directed toward the end of the metal rod 1.

The reinforcing material according to this invention is used as follows.

In FIG. 2, the side wall and bottom of the tank are connected to unit plate 4A.
It is assembled from.

The unit board 4A has a substrate 4 on the periphery of a right-angled substrate 41.
1 is provided with an upright joining edge 42 that stands upright relative to 1.

A reinforcing material a according to this invention is stretched between the side wall and the bottom.

The bent piece 12 of the reinforcing material a penetrates the base plate 41 of the unit plate 4A constituting the side wall or the bottom and projects to the back side, a slightly large washer 13 is fitted from the back side, and a nut 14 is tightened.

The collar 2 is drawn toward the base plate 41 by tightening the nut 14.

A gasket 3 is sandwiched between the collar 2 and the base plate 41.

In FIG. 3, two pieces of reinforcing material a according to the present invention are inserted into the side wall and dust volume of the tank, which is almost the same as in FIG. 2.

The ends of the two reinforcing members a are located symmetrically on both sides of the joint of the unit plate 4A.

The upper end of the reinforcing member a is fixed in the same manner as in FIG.

On the lower end side, a frame 5 is installed under the upright joint edge 42 of the unit plate 4A.
A U-shaped bent plate 6A is provided between the pedestal 5 and the unit plate 4A.

The bending plate 6A has its three bending pieces along the upper surface of the pedestal 5, the upright joining edge 42, and the substrate 41, respectively.

The bent piece 12 of the reinforcing material a passes through the substrate 41 and the bent plate 6A, and is fixed with a nut 14.

In FIG. 4, two reinforcing materials a according to this invention are inserted between the side wall (not shown) and the dust volume of a tank that is substantially the same as in FIG. 2.

The lower ends of the reinforcing members a are located near the contact points of the four unit plates 4A and symmetrically across the joints of the unit plates 4A.

A new curved board 6B having one piece along the substrate 41 and two pieces along the upright joining edge 42 is in contact with the lower side of the unit board 4A,
The bent piece 12 of the reinforcing material a passes through the substrate 41 and the bent plate 6B and is fixed with a nut 14.

In FIG. 5, two pieces of reinforcing material a according to the present invention are inserted into the side wall and dust volume of the tank, which is almost the same as in FIG. 2.

Both ends of the two reinforcing members a are located symmetrically on both sides of the joint of the unit plate 4A.

The lower end of the reinforcing member a is fixed in the same manner as in FIG.

The upper end passes through the substrate 41 and is fixed with a nut 14, and further passes through the plate 7 and is fixed with a nut 15.

The plate 7 straddles the upright joint edge 42 .

A stay bolt 8 extending horizontally is fixed to the upper part of the side wall.

In FIG. 6, a flock 9 is fixed within the tank, spanning the joint of unit plates 4A on the side wall and bottom of the tank, which are substantially similar to those in FIG. 2.

The block 9 has a T-shaped vertical wall 93 fixed between two parallel small plates 91 and 92.

The reinforcing material a according to this invention is stretched between the small flat plates 92 of the two blocks 9 and fixed in the same manner as in FIG. 2.

In the above tanks, the side walls and the bottom are usually perpendicular to each other, but if the bottom is inclined, the side walls and the bottom may not be perpendicular to each other.

Furthermore, the reinforcing material according to this invention can be used not only to support the side walls and the amount of dust, but also to support between the side walls that intersect with each other, between the side walls and the partition wall, and between the partition wall and the amount of dust.

Note that the unit plate can be made of metal (for example, iron) or reinforced synthetic resin (for example, gas fiber reinforced polyester resin).

Further, the substrate 41 can be provided with unevenness, and the substrate 41 can be provided with unevenness.
An angled abutment edge can be provided between the upright abutment edge 42 and the upright abutment edge 42 .

The reinforcing material according to this invention is easy to manufacture because it is made by attaching a collar to a metal rod.

Furthermore, since both ends of the metal rod in the longitudinal direction are bent to the same side and a screw is provided on the outer peripheral surface of the bent piece, the bent piece serves as a bolt.

Therefore, there is no need to use bolts.

Furthermore, since the bent piece is erected upright with respect to the flange surface, when the bent piece is passed through the tank wall and the nut is tightened, the flange surface tends to come into close contact with the tank wall.

Therefore, it is easy to make the gap between the collar surface and the tank wall airtight.

Moreover, since the bent portion is covered with a collar, the tank wall is prevented from being bent due to the spring action of the bent portion.

This invention has a number of advantages as mentioned above.
