Description

Technical Field

[0001] This utility model relates to the field of corrugated steel technology, specifically to a corner connection sealing device for prefabricated corrugated box culverts. Background Technology

[0002] Corrugated steel structures, composed of corrugated plates and flanges, are increasingly replacing concrete structures in engineering projects due to their advantages such as short construction time, buffering characteristics, and low cost. Box culverts are a common type of corrugated steel structure. Since corrugated steel structures are mainly composed of steel structural components, sealing has always been a difficult problem to solve. Existing corrugated steel structures mainly rely on gaskets for sealing, but these gaskets cannot properly solve the sealing problem at joints with gaps in the corrugated steel structure. Utility Model Content

[0003] This utility model proposes a corner connection sealing device for prefabricated corrugated box culverts, which solves the problem of gaps and poor sealing effect at the connection of corrugated steel structures in related technologies.

[0004] The technical solution of this utility model is as follows: it includes multiple corrugated plates forming a box culvert, with connecting flanges provided between adjacent corrugated plates. The edges of the corrugated plates along the axial direction of the box culvert are also provided with flanged flanges. T-shaped steel with a T-shaped cross-section is fixed on the flanged flange. The T-shaped steel includes intersecting horizontal and vertical plates. The flanged flange is located within the included angle of the horizontal and vertical plates. A sealing sleeve is provided at the connection point of adjacent T-shaped steels. The sealing sleeve includes a cross-arranged steel section connection part and a flange connection part. The steel section connection part is sealed and fixedly connected to the horizontal and vertical plates of the left and right T-shaped steels respectively, and the flange connection part is sealed and fixedly connected to the front and rear connecting flanges respectively.

[0005] In a further technical solution, the flange is integrally bent, a sealing gasket is provided between the flange and the T-shaped steel, and through holes of the same size are provided on the flange, the sealing gasket and the vertical plate, and the T-shaped steel is fixed by bolts passing through the through holes.

[0006] In a further technical solution, the horizontal plate is tightly attached to the outer wall of the corrugated plate.

[0007] In a further technical solution, the connecting flange is Z-shaped, and the interior of the connecting flange is provided with through holes. The connecting flange and the corrugated plate are fixed by bolts, and the corrugated plate and the connecting flange form a box-shaped channel.

[0008] In a further technical solution, the corrugated plate 1 is provided with reinforcing steel inside. The reinforcing steel is composed of No. I reinforcing steel component and No. II reinforcing steel component spliced ​​together by bolts. A connecting plate is provided on one side of both No. I reinforcing steel component and No. II reinforcing steel component. The connecting plate is provided with through holes inside. The connecting plate is fixed together with the connecting flange by bolts.

[0009] In a further technical solution, the two ends of the steel connecting part of the sealing sleeve are respectively provided with T-shaped grooves, the end of the T-shaped steel is inserted into the T-shaped groove, the end of the connecting flange is provided with a strip-shaped groove, and the flange connecting part of the sealing sleeve is inserted into the strip-shaped groove.

[0010] The working principle and beneficial effects of this utility model are as follows: A T-shaped steel is provided on one side of the corrugated plate. The T-shaped steel is fixed by bolts passing through through holes. The horizontal plate is tightly attached to the outer wall of the corrugated plate. By setting the T-shaped steel in cooperation with the sealing gasket, the sealing performance at the joint of the corrugated plate can be improved. When the vertical plate of the T-shaped steel is fixed by bolts, the sealing gasket will be squeezed to ensure the sealing effect in the axial direction of the corrugated plate. Since the T-shaped steel includes a horizontal plate and a vertical plate, the horizontal plate will squeeze the sealing gasket from the direction perpendicular to the axial direction of the corrugated plate, thus also ensuring the sealing effect in the direction perpendicular to the axial direction of the corrugated plate. Existing sealing measures directly install the sealing gasket at the joint of the corrugated plate, and the sealing effect is obviously poor. A sealing sleeve is provided at the joint of adjacent T-shaped steel. The sealing sleeve is fitted onto the outside of the port of the adjacent T-shaped steel. The sealing sleeve can tightly wrap the port of the T-shaped steel and connect the adjacent T-shaped steel, so that the T-shaped steel and the sealing sleeve form a whole, improving the sealing effect. However, if only the T-shaped steel is installed, the joint position of the T-shaped steel cannot be accurately aligned, which will produce gaps and affect the sealing effect.

[0019] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0020] As shown in the figure, a corner connection sealing device for a prefabricated corrugated box culvert includes multiple corrugated plates 1 forming the box culvert. A connecting flange 2 is provided between two adjacent corrugated plates 1. A flanged flange 5 is provided on the edge of the corrugated plate 1 along the axial direction of the box culvert. A T-shaped steel 3 with a T-shaped cross section is fixed on the flanged flange 5. The T-shaped steel 3 includes a horizontal plate 301 and a vertical plate 302 that intersect perpendicularly. The flanged flange 5 is located within the angle between the horizontal plate 301 and the vertical plate 302. A sealing sleeve 4 is provided at the connection of two adjacent T-shaped steel 3. The sealing sleeve 4 includes a cross-arranged steel section connection part 41 and a flange connection part 42. The steel section connection part 41 is sealed and fixedly connected to the horizontal plate 301 and the vertical plate 302 of the two left and right T-shaped steel 3, respectively. The flange connection part 42 is sealed and fixedly connected to the front and rear connecting flanges 2, respectively. The sealing sleeve 4 can tightly wrap the port of the T-shaped steel 3 and connect the adjacent T-shaped steels, so that the T-shaped steel 3 and the sealing sleeve 4 form a whole, improving the sealing effect. If only the T-shaped steel 3 is installed, the connection position of the T-shaped steel 3 cannot be accurately aligned, which will produce gaps and affect the sealing effect.

[0021] As a further improvement to this utility model, the T-shaped steel 3 is a T-shaped structural steel, composed of a horizontal plate 301 and a vertical plate 302. The two ends of the steel connecting part 41 of the sealing sleeve 4 are respectively provided with T-shaped grooves, and the end of the T-shaped steel 3 is inserted into the T-shaped groove. The end of the connecting flange 2 is provided with a strip-shaped groove, and the flange connecting part 42 of the sealing sleeve 4 is inserted into the strip-shaped groove.

[0022] As a further improvement to this utility model, the corrugated plate 1 is integrally bent with a flange 5 along the axial direction. A sealing gasket 6 is provided between the flange 5 and the T-shaped steel 3. The flange 5, the sealing gasket 6, and the vertical plate 302 are all provided with through holes of the same size. The T-shaped steel 3 is fixed by bolts passing through the through holes. The horizontal plate 301 is tightly attached to the outer wall of the corrugated plate 1. By setting the T-shaped steel 3 and the sealing gasket 6 together, the sealing performance at the joint of the corrugated plate 1 can be improved. When the vertical plate 302 of the T-shaped steel 3 is fixed with bolts, the sealing gasket 6 will be squeezed to ensure the sealing effect in the axial direction of the corrugated plate 1. Since the T-shaped steel 3 includes the horizontal plate 301 and the vertical plate 302, the horizontal plate 301 will squeeze the sealing gasket 6 from the direction perpendicular to the axial direction of the corrugated plate 1, thereby also ensuring the sealing effect in the direction perpendicular to the axial direction of the corrugated plate 1. The existing sealing measures directly install the sealing gasket at the joint of the corrugated plate 1, and the sealing effect is obviously poor.

[0023] As a further improvement to this utility model, the connecting flange 2 is Z-shaped and is fixedly installed at both ends in the direction perpendicular to the axis of the corrugated plate 1. The connecting flange 2 has through holes inside. The connecting flange 2 and the corrugated plate 1 are fixed by bolts. The corrugated plate 1 and the connecting flange 2 form a box-shaped channel.

[0024] As a further improvement to this utility model, the corrugated plate 1 is provided with a reinforcing steel 7 inside. The reinforcing steel 7 is composed of a No. I reinforcing steel component 701 and a No. II reinforcing steel component 702 connected by bolts. A connecting plate 703 is provided on one side of both the No. I reinforcing steel component 701 and the No. II reinforcing steel component 702. The connecting plate 703 is provided with a through hole inside. The connecting plate 703 is fixed to the connecting flange 2 by bolts. The connecting flange 2 is provided with a threaded hole of the same size as the through hole inside the connecting plate 703 at the installation position of the connecting plate 703. By providing a reinforcing steel 7 inside the corrugated plate 1, the overall compressive strength of the box-type corrugated duct composed of the corrugated plate 1 and the connecting flange 2 can be enhanced, and the stability can be improved.
