Description

[Detailed description of the invention] (Industrial field of application) This invention relates to a prefabricated storage tank, and specifically relates to a roof reinforcement structure.

(Prior Art) In a prefabricated storage tank, a roof is constructed by arranging a plurality of roof panels horizontally and joining their outer peripheral edges to each other.

In this prefabricated storage tank, the joint intersections where the joint surfaces of the roof panels intersect are the weak points in the structure. is being supported.

(Problem to be solved by the invention) However, since the roof of a prefabricated storage tank is composed of a large number of roof panels, the number of joint intersections of these roof panels is also large, so it is necessary to install a support at each joint intersection. If they were installed, the number of supports would also be large. The greater the number of supports, the higher the unit price of the storage tank will be, and the more troublesome the assembly work will be.

In addition, as the number of columns increases, the structure inside the storage tank becomes complicated, and this creates a problem in that the inside of the storage tank gets in the way and becomes difficult to clean.

(Means for solving the problem) The present invention was made to solve the above problem, and its gist is to arrange a plurality of roof panels horizontally and connect their outer peripheral edges to each other. In a prefabricated storage tank configured to form a roof by joining, a longitudinal reinforcing member having a horizontal part supporting the roof panel and a hanging part hanging down from the horizontal part is joined to the roof panel. A joint member in the form of a cross of two plates having a certain width in the vertical direction is placed along the plane and is placed at the joint intersection where their joint surfaces intersect, and the joint member is used to A beam is constructed by connecting the reinforcing members to each other, and the joint member is supported by a support installed inside the storage tank, and a notch corresponding to the joint member is formed at the upper end of the support. The joint member is then engaged with the notch, thereby determining the relative position of the joint member and the support.

(Function) In this invention, a plurality of reinforcing members are connected to each other by joint members to form a beam,
Since these beams support the roof panels from below, there is no need to erect pillars at each joint intersection of the roof panels to support the roof panels. This reduces the number of supports, lowering the unit price of the storage tank, making it easier to assemble the tank, and making cleaning inside the tank easier.

Note that it has already been done to extend a single beam from one side wall of a storage tank to the opposite side wall, and to support a roof panel by this beam. However, in this case, the length of the beam is uniquely determined by the size of the storage tank, so if the size of the storage tank changes, this beam cannot be used to cope with the change.

In contrast, in the present invention, multiple reinforcing materials are connected to each other to form a beam, so by preparing in advance multiple types of reinforcing materials with different lengths, various sizes can be created. This makes it possible to deal with large storage tanks.

Another feature of the present invention is that the relative positions of the reinforcing members are determined by engaging the joint members that connect the reinforcing members with the notches formed in the upper ends of the columns.

In conventional prefabricated storage tanks, the distance (height) from the top surface of the bottom panel of the storage tank to the supported part of the roof panel or the supported part of the beam does not exactly match the height of the support, which causes the support In order to prevent the columns from falling due to gaps between the upper ends and these roof panels or beams, it has been necessary to fix the upper ends of the columns to the roof panels or beams.

However, in this case, a special member for fixing the column and a fixing operation are required, which complicates the assembly operation of the storage tank.

In contrast, in the present invention, the beam and the upper end of the column are positioned and fixed by the engagement between the joint member and the notch in the column, so special members and work for fixing the column as described above are not required. do not need.

Furthermore, the present invention has the advantage that reinforcing members of different sizes can be connected without any particular problem since the joint member and the reinforcing member are fixed by the vertical plate-shaped portion.

(Example) Next, an example of the present invention will be described in detail based on the drawings.

In Figure 2, 10 is a concrete base;
Reference numeral 12 denotes a pedestal, and on this pedestal 12 is placed a storage tank made up of a number of bottom panels 14, side wall panels 16, and roof panels 18 joined together. still,
In this example, square panels measuring 1 m x 1 m are used as the bottom panel 14 and the roof panel 18, and a large vertically long panel measuring 1 m x 2 m is also used as the side wall panel 16. .

As shown in FIG. 1, beams 15 and 25 are arranged at right angles to each other on the back side of the roof panel 18, and each roof panel 18 is supported by these beams 15 and 25. The beam 15 includes angle members 22a and 22b (length 1 m to 3 m) as reinforcing members arranged along the joint surface of the roof panel 18,
The angle members 22a,
22b, and one end is joined to the side wall panel 16 by a fixing member 46.

On the other hand, the beams 25 are angle members 24a and 24b that are also arranged along the joint surface of the roof panel 18.
(1 m to 3 m in length) and a joint member 26 that connects them, and similarly to the beam 15, one end thereof is joined to the side wall panel 16 by a fixing member 46 (not shown). ).

Each angle member 2 constituting these beams 15, 25
2a, 22b, 24a, 24b are roof panels 1
8, a horizontal portion 32 in contact with the lower end surface of the hilange 20;
It has an L-shaped cross section, including a hanging portion 34 that falls from a horizontal portion 32. And this hanging part 34
Two bolt holes 36 are bored at each end in the longitudinal direction, and the bolt holes 36 are fastened to the joint member 26 or the fixing member 46 at these portions.

On the other hand, the joint member 26 is a member in the form of two plates criss-crossed, and has four connecting pieces 28 extending radially from the center, and each connecting piece 28 has a bolt hole 30. Two holes are drilled in each hole.

The above angle members 22a, 22b, 24a, 24
b have the same or different lengths, and depending on the length, the hanging portion 34
The width is narrow or wide. The joint member 26 is made wider in the vertical direction by a certain amount than the widest one of these hanging parts 34.

This joint member 26 is supported by a column 40 erected inside the storage tank. Post 40
has a head 42 at the upper end, and four notches 44 are formed in the head 42, into which the joint member 26 is fitted.

The fixing member 46 (here, the angle member 22a
(described below) is a T-shaped type having a fixing part 48 that is brought into close contact with the inner surface of the flange 20 of the roof panel 18, and a connecting part 50 that is fastened to the angle member 22a. , and a rectangular notch 5 is provided in the fixing part 48.
6 and two bolt holes 52 are formed. The cutout 56 is for avoiding interference with the flange 20 of the roof panel 18 (the flange in the same direction as the angle member 22a), and the bolt hole 52 is
As shown in FIG. 3, fixing member 46 is attached to roof panel 1.
8 and side wall panel 16. The bolt holes 52 are provided at positions that match bolt holes previously drilled in the flanges 20 of the side wall panels 16 and the roof panel 18.

On the other hand, the connecting portion 50 extends in the same direction as the joint surface of the roof panel 18, and has two bolt holes 54 therein.
is formed. Bolt hole 54 is made of angle material 2
This hole is for connection with 2a.

Next, the operation of the roof reinforcement structure of this example will be explained.

In this example, angle members 22a, 22b,
Beams 15, 25 are constituted by 24a, 24b, etc., and the roof panel 18 is formed by these beams 15, 25.
is supported. Therefore, there is no need to provide a support at each joint intersection of the roof panel 18. It is sufficient to erect the support 40 only at the portion where the angle members 22a, 22b, 24a, 24b, etc. intersect (the portion where the joint member 26 is arranged).

Also, the width of the joint member 26 is the same as that of the angle member 2.
2a, 22b, 24a, and 24b, the width is always wider than the width of the hanging portions 34 of the adjacent angle members 34 as shown in FIG. As shown, even if the angle member hanging portions 34 have different widths, there is no problem in supporting the joint member 26 by the support 40. This is because the lower end of the joint member 26 is always located lower than that of the angle member.

By the way, regarding the fixing members for fixing the beams 15 and 25 to the side wall panel 16, it is also possible to form the fixing part 60 with the same width as the connecting part 62, as shown in FIG. 6A. However, in this case, the fastening portion to the side wall panel 16 is located below the fixing member 46 shown in FIG. 1, as shown in FIG. 6B. In other words, it is located below the fastening area between the roof panel 18 and the side wall panel 16.
The side wall panel 16 is provided with bolt holes for fastening to the flange 20 of the roof panel 18.
When the fixing member is configured as shown in FIG. 6, bolt holes for fastening to the fixing member must be provided in the side wall panel 16 separately from bolt holes for fastening to the roof panel 18. These bolt holes are provided in advance when the side wall panel 16 is produced at the factory, so when assembling the storage tank, be sure to use the side wall panels 16 that have separate bolt holes for fastening them to the beams 15 and 25. It is also necessary to bring it to the site where it will be installed. That is, it is necessary to assemble the storage tank while sorting the side wall panels 16, which makes the storage tank assembly work complicated.

On the other hand, the fixing member 46 in FIG.
Both ends of 8 are the flanges 2 on the roof panel 18
It has a shape that extends upward to the inner surface of 0.
The bolt holes 52 are provided at the same positions as the bolt holes for joining the panels in the side wall panel 16 and the roof panel 18. For this reason, side wall panel 1
6, there is no need to provide a separate bolt hole for fastening with the fixing member 46, and therefore there is no need to select side wall panels when assembling the storage tank.

Although the embodiments of the present invention have been described in detail above, the present invention can be configured in other forms.

For example, the reinforcing members that are connected to each other to form a beam are not limited to the above-mentioned angle members, and various other forms of reinforcing members can be used. It is possible to configure it in a different form.

In addition, the present invention can be modified in various forms without departing from the spirit thereof.

(Effects of the invention) As described in detail above, the present invention constructs a beam with a plurality of reinforcing materials and joint members, supports the roof panel with this beam, and supports the joint member with a support. It was designed to be supported.

According to the present invention, it is possible to reduce the number of supports, and the structure inside the storage tank can be simplified. Additionally, cleaning the inside of the storage tank becomes easier. Furthermore, the length of the beam can be changed as appropriate depending on the size of the storage tank, so there is no need to prepare beams for storage tanks of various sizes.
