Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a structure assembled by joining a plurality of panels, and more particularly, to a panel assembly having a high degree of corrosion resistance.

[Prior Art] Conventional panel structures are, for example, shown in FIGS. 5a and 5b.
It is assembled by using panels 101 as shown in the figure and joining them in the manner shown in FIG. 4. That is, the panel 101, which is constructed by laminating the resin corrosion-resistant layer 103 and the reinforcing layer 104, has its edge portion bent in a cross-sectional shape. Then, in order to make the corrosion-resistant layers 103.103 of the bent portions 109.109 of adjacent panels 101.101 face each other and to seal the joint, a backing made of an elastic material such as rubber or a cassette 106 is sandwiched between them. The adjacent panels 101101 are joined by tightening the bent portions 109 and 109 using the pin h107 and the nut 108. By joining multiple panels in this way, you can create, for example, a gas-liquid contact device! Assembling the intended structure such as.

[Problems to be Solved by the Invention] However, in conventional panel structures, the bent portions of the panels are joined through a backing made of an elastic material such as rubber or a gas get, so it is difficult to connect a large number of panels. When bonded, a dimensional error occurs, and this error becomes a large error that cannot be tolerated by the entire structure, resulting in a problem that high dimensional accuracy cannot be achieved.

In addition, the sealing of the joints may become insufficient, and highly corrosive liquids and gases may leak from the inside, damaging the structure from the outside.
However, there was a problem in that the reliability of the corrosion-resistant structure was not sufficient.

It is an object of the present invention to solve the above-mentioned problems and to provide a highly reliable panel-type corrosion-resistant structure that has high dimensional accuracy and excellent sealing performance at the joints of panels.

[Means for Solving the Problems] In the panel-type corrosion-resistant structure of the present invention, each panel is formed by laminating a resin corrosion-resistant layer and a reinforcing layer that reinforces the resin corrosion-resistant layer, and at the joint thereof, The edges of each panel are bent into an L-shaped cross section so that the resin corrosion-resistant layers come into contact with each other, and the resin corrosion-resistant layers at the L-shaped bent portions of each panel come into contact with each other at the joints of each panel. For the resin corrosion-resistant layer filled in the groove of the groove formed by! - a sealing member having adhesive properties, a conductive wire material disposed at the bottom of the groove of the groove for detecting pinholes in the sealing member, and a conductive wire material arranged to cover the groove filled with the sealing member; and a backing plate welded to the resin corrosion-resistant layer of the panel.

Further, in another panel type corrosion-resistant structure of the present invention, the panels are joined by pressing the bent portion of the panel with a metal joining portion reinforcing member.

In this invention, various thermoplastic resins having corrosion resistance and weldability, such as polyvinyl chloride resin and polypropylene resin, can be used as the resin corrosion-resistant layer.

Further, as the reinforcing layer, various materials such as FRP, which is a matrix made of polyester or vinyl ester and reinforced with glass 414III, can be used.

Further, as the sealing member, various materials having adhesive properties with the resin corrosion-resistant layer can be used, such as a resin putty having a matrix of silicone rubber or vinyl ester mixed with a filler such as 8102.

As a backing plate, it has corrosion resistance equivalent to that of a resin corrosion-resistant layer, and
Various materials with resin corrosion-resistant layer and welding adhesive properties, such as:
The same material as the resin corrosion-resistant layer can be used.

Further, as the conductive wire material, carbon fiber or other conductive wire material can be freely selected.

[Function] Panel type corrosion resistance of this invention! In the f4 body, the resin corrosion-resistant layer of each panel exhibits corrosion resistance against corrosive substances, and the reinforcing layer provides structural strength to this resin corrosion-resistant layer. The resin anti-corrosion layers at the curved portions of the plurality of panels to be joined, each having a cross-sectional shape, come into contact with each other, and the sealing member filled in the groove of the groove formed thereby adheres to and joins the resin anti-corrosion layer. The plate is welded to the resin corrosion-resistant layer of the joined panel to ensure a secure seal and cover the groove.
It provides a more reliable seal at the joint and provides mechanical strength to the joint. Furthermore, the conductive wire material embedded in the groove of the groove acts as a conductor when detecting a pinhole in the sealing member using a pinhole tester using an electric discharge method, and when a pinhole exists in the sealing member, the conductive wire material acts as a conductor when detecting a pinhole in the sealing member. An arc is generated between the pinhole tester and the pinhole tester to detect the pinhole.

Further, the metal joint reinforcing member strengthens the joint and improves the mechanical strength of the entire structure.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings. The panel type corrosion-resistant structure in this embodiment is a freezing contact device 2 for treating halogen gas with an inorganic acid water fj liquid such as hydrochloric acid, as shown in outline in FIG.

As shown in Figures 3a and 3b, the panel 1 is constructed by laminating a resin corrosion-resistant layer 3 made of polyvinyl chloride resin and a reinforcing layer 4 made of F'RP made of a polyester matrix reinforced with glass fiber. . The edge portion of the panel 1 is bent in a cross-sectional shape so that the tree@M eclipse layer 3 is on the mountain side to form a bent portion 9. Further, in the center of the panel 1, a depression lO is formed so that the resin corrosion-resistant layer 3 side is concave in order to absorb the stress applied to the panel 1 when a plurality of panels 1 are joined. However, in the present invention, the panel 1 does not necessarily have to have the above-mentioned shape, and a panel having a shape without a recess as shown in FIGS. 5a and 5b may also be used. In the panel 1 having the above structure, as shown in FIG.
It is arranged so as to come into contact with the bent portion 9 of the adjacent panels l to be joined. At this time, the resin corrosion-resistant layers 3.3 of each panel 1.1 face and abut against each other, forming a groove 11. At the bottom of this groove 11, carbon fibers are disposed along the bottom of the groove 11 as a conductive linear material 12.

And, for the groove 11, vinyl ester wood) l'f
If a resin putty containing 95 parts by weight of calcium carbonate, 5 parts by weight of glass chop, and 23 parts by weight of 5iO per 100 parts by weight is filled as the sealing member 13, and the groove 11 filled with the sealing member 13 is further made of polyvinyl chloride resin. It is covered by a contact plate 14. This contact plate 14 is welded to the resin corrosion-resistant layer 3.3 of the panel 1.1 to be joined. 14a shows the welded part, while the bent part 9 of the panel 1
are tightened by bolts 7 and nuts 8 via metal joint reinforcing members 15 having an L-shaped cross section, and as a result, adjacent panels 1.1 are firmly joined. By combining and joining panels 1 of a predetermined shape in this manner, a square gas-liquid contact device having a halogen gas inlet 16 and a treated waste outlet 17 as schematically shown in FIG. 2 is created. 2
can be assembled.

Corrosion resistant panel type constructed like this! In the case of R, since the rigid resin corrosion-resistant layers 3 are in contact with each other, even if a plurality of panels 1 are joined, unexpected dimensional errors due to deformation of the backing, etc., as in the conventional example will not occur, and
The groove 11 at the joint of the panel 1 is double-sealed by the sealing member 13 and the backing plate 14, which improves sealing performance and prevents liquid leakage from inside. Since the conductive wire member 12 is embedded, it is possible to easily test whether or not there is a pinhole in the seal member 13 using a pinhole tester that utilizes electric discharge between the wire member 12 and the wire member 12.

In the above embodiment, a metal joint reinforcing member 15 is used to strengthen the joint, but in cases where the structure is small or lightweight, for example, it may not be necessary to use it, or it may be partially used. You can obtain the necessary strength just by using it. Furthermore, the shape of the bent portion 9 at the edge of the panel does not have to be strictly L-shaped; it is sufficient that the resin corrosion-resistant layers face each other and come into contact with each other during bonding. It may also be a shape.

[Effects of the Invention] The panel-type corrosion-resistant structure of the present invention has the advantage that even if a plurality of panels are joined together, the rigid resin corrosion-resistant layers are in contact with each other at the joints of the panels. No dimensional errors occur, and the dimensional accuracy of the entire structure can be improved. Furthermore, since the groove at the joint of the panel is double-sealed by the sealing member and the backing plate, sealing performance is improved, and a panel-type corrosion-resistant structure with high reliability in terms of corrosion resistance can be obtained.

Furthermore, since a conductive linear member is embedded in the groove, it is possible to easily test whether or not there is a pinhole in the sealing member using a pinhole tester that uses electrical discharge between the conductive wire member and the conductive wire member, which improves corrosion resistance. reliability is further improved.

In addition, a panel-type corrosion-resistant structure in which panels are joined with metal joint reinforcement members has improved mechanical strength, so it can be applied to structures that require high strength, such as large structures.
