Description

Technical Field

[0001] The invention relates to the field of waterproof inspection cover plates, and in particular to a transfer station structure. Background Art

[0002] The transfer station is an important building for transporting coal in a thermal power plant. It is a transfer station before the coal enters the main plant. In order to meet the needs of inspection and maintenance of the transport belt, a manhole directly connected to the ground will be set up on the belt layer of the transfer station as a vertical passage for inspection materials. When other functional rooms are arranged in the lower part of the transfer station according to the needs of the power plant, the roof of the room needs to be equipped with an inspection hole and its movable cover to ensure that it can be easily opened and closed during maintenance. Since the roof of the lower room is in an open-air state and the height of the transfer station is relatively high, the power plant adopts a frame-shear wall structure. When the inspection hole needs to be arranged close to the shear wall according to process requirements, the cover solution becomes a difficulty. How to ensure that rainwater on the roof does not leak into the room from the inspection hole is a key issue in the cover design.

[0003] In order to facilitate maintenance, the existing manhole cover is set to be open and assembled. It is divided into two cover plates with a channel steel frame structure. The cover plates are simply spliced ​​against each other, and the two ends of the cover plates are placed on the concrete beams beside the manhole. Some manhole covers are also provided with lifting rings. However, the existing technology has the following shortcomings: 1. The cover plates are not waterproof and sealed. There are gaps in the following three locations, which can easily cause rainwater to leak into the lower room: (1) The gap left by the simple leaning between the cover plates; (2) The installation gap between the cover plate and the concrete edge left to meet the on-site construction error; (3) The installation hole reserved in the patterned steel plate at the lifting ring. 2. If the gap in the cover plate is sealed with waterproof material, the waterproof layer needs to be cleaned before each maintenance, and then re-sealed afterwards, which is time-consuming, labor-intensive and costly.

[0035] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a replaceable connection, or an integral connection, it can be a mechanical connection, it can be an electrical connection, it can be a direct connection, it can be indirectly connected through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0036] Combination Figure 1-8 As shown, a transfer station structure comprises: a concrete wall 1, a drainage member 2, an anti-edge 3 and a cover plate assembly 4, one side of the anti-edge 3 is connected to one side of the concrete wall 1, and an inspection hole 5 is defined between the anti-edge 3 and the side of the concrete wall 1; the drainage member 2 is arranged on the side of the concrete wall 1 facing the inspection hole 5, a drainage groove 21 is arranged on the top of the drainage member 2, the drainage member 2 is located above the inspection hole 5, and extends along the edge of one side of the inspection hole 5 facing the concrete wall 1; The cover plate assembly 4 includes: a plate body 41, a retaining eave 42, a water retaining portion 43, and a reinforcing rib 44. The plate body 41 covers the inspection hole 5. The reinforcing rib 44 is arranged on the bottom surface of the plate body 41 and is located in the inspection hole 5. The water retaining portion 43 is protruding upward along the edge of one side of the plate body 41 relative to the concrete wall 1, and the water retaining portion 43 is connected to the drainage member 2. The retaining eave 42 is protruding downward along the outer peripheral edge of the plate body 41 and is enclosed by the outer periphery of the anti-edge 3.

[0037] Exemplarily, the inspection hole 5 is a transfer station inspection hole 5 of conventional size, with a net size of 3000 mm in length and 2500 mm in width; the reverse edge 3 is a concrete reverse edge 3, and the height difference between the top surface of the reverse edge 3 and the roof structure surface should be greater than the thickness of the building surface layer. In this embodiment, the thickness of the reverse edge 3 is 100 mm, and the plate body 41 is a 4 mm thick patterned steel plate. When maintenance is needed, the inspection hole 5 can be entered by simply removing the cover assembly 4; when the inspection hole 5 needs to be kept closed, the cover assembly 4 is directly buckled on the inspection hole 5, and the plate body 41 and the eaves 42 cover the outer periphery of the inspection hole 5 and the reverse edge 3, and are hooked on the edge of one side of the drainage member 2 through the water retaining portion 43. When rainwater drops on the water retaining portion 43, it can flow into the drainage groove 21 along the water retaining portion 43, or flow down to the plate body 41 along the water retaining portion 43, and the rainwater on the plate body 41 can flow out to the outside of the eaves 42 and the reverse edge 3 along the eaves 42, and the reinforcing ribs 44 are against the inner periphery of the reverse edge 3, which effectively prevents rainwater from splashing or overflowing into the inspection hole 5.

[0038] In some embodiments, an embedded plate 6 is further included; the embedded plate 6 is embedded in the concrete wall 1 , and the drainage member 2 is connected to the embedded plate 6 .

[0039] Exemplarily, the embedded plate 6 is a steel plate with a length of 150 mm and a width of 8 mm, and the drainage component 2 is welded on the steel plate, which is conducive to more stable installation of the drainage component 2.

[0040] In some embodiments, the drainage component 2 includes: a water receiving plate 22, a first side plate 23, and a second side plate 24; the first side plate 23 and the second side plate 24 are respectively protruded upward along the opposite side edges of the water receiving plate 22, and the first side plate 23, the second side plate 24 and the water receiving plate 22 jointly define the drainage groove 21, the first side plate 23 is in contact with the concrete wall 1, and the water retaining portion 43 is connected to the second side plate 24.

[0041] Exemplarily, the drainage groove 21 has a net width of 20 mm and a depth of 50 mm, is formed by bending a 4 mm thick steel plate, and has a 0.5% slope toward the outside of the plate body 41. The drainage groove 21 can store water or drain water, which is helpful to prevent rainwater from seeping into the inspection hole 5.

[0042] In some embodiments, the water retaining portion 43 includes: a water retaining plate 431 and a connecting plate 432; the water retaining plate 431 is protruding upward along the side edge of the plate body 41 facing the concrete wall 1, and the connecting plate 432 is connected to the top side edge of the water retaining plate 431, and the connecting plate 432 is hooked onto the second side plate 24.

[0043] Exemplarily, the water retaining plate 431 is 270 mm high, the top width of the connecting plate 432 is 22 mm, the height of the part of the connecting plate 432 hooked on the second side plate 24 is 35 mm, and when the water retaining portion 43 is hooked on the second side plate 24, a net distance of more than 5 mm is retained from the second side plate 24, which is beneficial to ensure that rainwater on the surface of the concrete wall 1 is received and discharged through the drainage groove 21 to prevent leakage into the lower room.

[0044] In some embodiments, the reinforcing ribs 44 include multiple channel steels 441, some of the channel steels 441 extend longitudinally and are spaced apart in sequence transversely, and the remaining channel steels 441 extend transversely and are spaced apart in sequence longitudinally, and multiple channel steels 441 are cross-arranged with each other; and the channel steels 441 are all provided along the bottom edge of the plate body 41.

[0045] For example, the longitudinally spaced channel steels 441 are longitudinal channel steels 441, which are used as the main load-bearing beams and are 2690 mm long. The transversely spaced channel steels 441 are transverse channel steels 441, which are used as the cover plate sealing beams and transverse stabilizing beams and are 910 mm long. This is beneficial to improving the structural stability of the cover plate assembly 4.

[0046] In some embodiments, a groove portion 31 is provided on the inner side of the edge of the reverse edge 3 opposite to the concrete wall 1 , and the channel steel 441 corresponding to the groove portion 31 is placed in the groove portion 31 .

[0047] For example, both ends of the longitudinal channel steel 441 can be placed in the groove, and the placement length is 95 mm, which is conducive to more convenient and stable installation of the cover plate assembly 4 on the inspection hole 5.

[0048] In some embodiments, the cover plate assembly 4 further includes a lifting ring 45 , which is disposed above the plate body 41 and corresponds to a position where each channel steel 441 crosses.

[0049] For example, the lifting ring 45 is made of 20 mm diameter steel bars, 4 in total, welded to the upper surface of the longitudinal channel steel 441, and the patterned steel plate reserves a hole with a diameter of 36 mm at the lifting ring 45 to facilitate welding of the lifting ring 45. When maintenance is required, the cover plate assembly 4 can be better lifted by the lifting ring 45, and the setting of the lifting ring 45 is conducive to ensuring the waterproof function of the cover plate assembly 4.

[0050] In some embodiments, the bottom end of the drainage member 2 is at least 150 mm higher than the top end of the channel steel 441. Taking the height of the longitudinal channel steel 441 plus the reserved height of 40 mm as an example, the lowest point of the drainage member 2 is 200 mm higher than the upper surface of the longitudinal channel steel 441. When the cover plate assembly 4 needs to be lifted for maintenance, the cover plate assembly 4 can be lifted vertically upward by 165 mm first, and then moved horizontally, which is conducive to ensuring that the reinforcing rib 44 does not collide with the anti-edge 3 and the drainage member 2.

[0051] In some embodiments, the retaining eaves 42 protrude downwards by 50 to 200 mm along the outer peripheral edge of the plate body 41 , which is helpful to prevent rainwater from drifting into the gap between the anti-edge 3 and the cover plate assembly 4 .

[0052] In some embodiments, the plate body 41 , the eaves 42 , and the water retaining portion 43 are integrally formed by a steel plate, and the reinforcing ribs 44 are steel components, and the reinforcing ribs 44 are welded to the plate body 41 .

[0053] For example, after the steel plate covers the conventional-sized transfer station inspection hole 5, it cantilevers outward by 125mm and then bends downward by 100mm to form a retaining eave 42, which is buckled on the reverse edge 3; one end of the steel plate protrudes 270mm in the vertical direction, the top is horizontally bent by 22mm, and then bent downward by 35mm to form a water retaining part 43, which is buckled on one side of the drainage member 2; a 5mm gap is reserved between the integrally formed cover plate and the surrounding structure, and the cover plate can be simply pressed against when installed. The cover plate is integrally formed, and there is no problem of gap seepage caused by the assembly of the block cover plates, which is conducive to ensuring that rainwater cannot leak from all positions of the inspection hole 5 into the transfer station room.

[0054] If the length and width of the inspection hole 5 change, the length of the longitudinal channel steel 441 and the transverse channel steel 441, the model of the longitudinal channel steel 441, the elevation of the drainage ditch 21 on the concrete wall 1, and the height of the water retaining plate 431 and the connecting plate 432 can be adjusted according to the above principles.

[0055] According to the disclosure and teaching of the above description, those skilled in the art to which the present invention belongs may also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the scope of protection of the claims of the present invention. In addition, although some specific terms are used in this specification, these terms are only for the convenience of description and do not constitute any limitation to the present invention.
