Description

Technical Field

[0001] This utility model relates to a cover plate, specifically a stainless steel arc-shaped cover plate for a water tank. Background Technology

[0002] As a common space covering solution in modern architecture, curved cover structures have been widely used in public buildings, industrial plants, and environmental protection facilities (such as sewage treatment plants and garbage transfer stations). Currently, however, these curved cover structures suffer from issues such as generally low connection strength and limited water-stopping effect when adjacent covers are sandwiched with rubber. Furthermore, traditional curved covers typically rely on internal frame structures for load-bearing support; if corrosive gases are released from the pool, this can accelerate structural aging and shorten its lifespan. Alternatively, more corrosion-resistant materials may need to be used, increasing costs. Utility Model Content

[0003] Purpose of the invention: The purpose of this utility model is to overcome the shortcomings of the prior art and provide an arc-shaped cover plate structure with high overall strength, good water-stopping effect between adjacent cover plates, and solves the problems of short service life and difficulty in replacement through external support.

[0004] Technical Solution: To solve the above-mentioned technical problems, the arc-shaped cover plate structure of this utility model includes several arc-shaped cover plate units. Each arc-shaped cover plate unit includes a plate body. The cross-section of the plate body is a corrugated structure. A folded edge I is provided on one side of the plate body. At least one rib I is provided on the folded edge I. A dead edge I is provided at the end of the folded edge I. A folded edge II is provided on the other side of the plate body. At least one rib II is provided on the folded edge II. A dead edge II is provided at the end of the folded edge II. The ribs I and II are staggered.

[0005] Furthermore, the plate body includes a bottom surface, an inclined surface, and a top surface.

[0006] Furthermore, a transverse rib I is provided on the bottom surface of the plate.

[0007] Furthermore, longitudinal ribs are provided on the top surface of the plate, and transverse ribs II are provided on the inclined surface of the plate.

[0008] Furthermore, two raised ribs I are provided on the folded edge I, and two raised ribs II are provided on the folded edge II, with the height of the raised ribs II being higher than that of the raised ribs I.

[0009] Furthermore, both the bitten edge I and bitten edge II are flanges.

[0010] Furthermore, connecting holes are provided on both folded edge I and folded edge II.

[0011] Furthermore, an elastic sealing rubber is provided between adjacent arc-shaped cover plate units. Unequal angle steel is bolted to the outer sides of the folded edges I and II of adjacent arc-shaped cover plate units. The unequal angle steel is provided with a raised rib III, a locked edge III, and bolt holes, and the bolt holes are aligned with the connecting holes on the folded edges. They are connected by bolts.

[0012] Furthermore, when the span of the pool is large, a support structure is provided outside the arc-shaped cover plate unit.

[0013] Furthermore, the support structure includes a support beam and a connecting rod. One end of the connecting rod is connected to the support beam, and the other end is bolted to the locking edge III of the unequal angle steel. The connecting rod is adjustable, i.e., used to adjust the tension between the support beam and the unequal angle steel.

[0014] Beneficial Effects: Compared with the prior art, the significant advantages of this utility model are: the overall structure of this utility model is reasonably designed, consisting of several arc-shaped cover plate units connected together, which facilitates installation and transportation. The arc-shaped cover plate unit includes a plate body with a corrugated cross-section, resulting in high structural strength. Folded edges are provided on both sides of the plate body, with raised ribs on the folded edges and a locking edge at the end of the folded edges. The ribbed folded edges and the locking edge at the end of the folded edges increase strength and enhance the water-stopping effect when rubber is clamped. A transverse rib I is provided on the bottom surface of the plate body, a longitudinal rib is provided on the top surface of the plate body, and a transverse rib II is provided on the inclined surface of the plate body, further improving structural strength. Unequal angle steel connected by bolts is provided on the outside of the folded edges to enhance the overall strength of the arc-shaped cover plate. When the span of the pool is large, a supporting structure is provided on the outside of the arc-shaped cover plate unit, solving the problems of short service life and difficulty in replacement of the internal supporting structure used previously, thus meeting practical usage requirements.
