Description

Technical Field

[0001] The present invention belongs to the technical field of trestles, and particularly relates to a waterproof joint of the deformation joint between a trestle and a transfer station. Background Art

[0002] Trestles are widely used for cargo transportation or for people to pass through. Structurally, trestles are often used in combination with transfer stations. Regarding the deformation joint at the junction of the trestle and the transfer station, it needs to meet the deformation requirements of the trestle in the vertical direction because the trestle will vibrate in the vertical direction when transporting goods or people passing through.

[0003] Taking the coal transportation and power generation scenario involved in cargo transportation as an example, the specification requires that the deformation joint should not pass through water-using rooms such as toilets / washrooms, lavatories, and bathrooms, and there is no deformation joint node at the water-using room in the traditional atlas practice; in the industrial plant area of coal transportation and power generation, both the trestle for coal transportation and the transfer station need to be provided with water flushing, and the water quality is turbid after flushing. For the waterproof joint at the deformation joint between the two, according to the traditional atlas design, there are bolt anchorages. Due to vibration and aging, water leakage will occur, affecting the service life of the trestle and polluting the outer wall of the transfer station. Therefore, there is an urgent need in the art for a waterproof joint at the deformation joint between the trestle and the transfer station, so as to be a better structure for preventing water leakage.

[0044] For ease of understanding of the embodiments of the present invention, further explanatory descriptions will be given below with specific embodiments as examples in conjunction with the accompanying drawings, and each of the accompanying drawings does not constitute a limitation on the embodiments of the present invention.

[0045] For better understanding, as Figure 1-2 shown, the present invention discloses a waterproof joint of the deformation joint between a trestle and a transfer station, which is characterized in that the waterproof joint, as a structure, includes,

[0046] a trestle structure part, a transfer station structure part, and a tread plate structure part;

[0047] At a first end of the transfer station structure part facing the trestle structure part, the transfer station structure part includes an "┘"-shaped notch, and the "┘"-shaped notch is provided with a first steel structure in the shape of "凵" and having a first hollow part;

[0048] At a second end of the trestle structure part facing the transfer station structure part, the trestle structure part includes a "└"-shaped notch, and the "└"-shaped notch is provided with a second steel structure in the shape of "凵" and having a second hollow part;

[0049] The tread plate structure part is a third structure in the shape of "冂" and having a third hollow part,

[0050] wherein,

[0051] The left vertical surface of the third structure is inserted into the first hollow part of the first steel structure, and the lower end of the left vertical surface of the third structure is movably abutted against the bottom surface of the first steel structure;

[0052] The right vertical face of the third structure is inserted into the first hollow part of the second steel structure, and the lower end of the right vertical face of the third structure is movably abutted against the bottom surface of the second steel structure.

[0053] So that,

[0054] The space between the left vertical facade of the third structure and the left vertical facade of the first steel structure is used as the first type of waterproof structure I;

[0055] The space between the right vertical facade of the third structure and the right vertical facade of the second steel structure is used as the first type of waterproof structure II;

[0056] The space between the left and right vertical facades of the third structure is used as a second type of waterproof structure.

[0057] In this embodiment, a step plate is provided above the expansion joint to form a step height. The left and right vertical surfaces of the third structure serve as the two ends and are movably abutted into the grooves formed by the hollow parts of the first and second steel structures to ensure elastic connection (Note: This is to cope with the vibration situation when the trestle and transfer station are working).

[0058] Preferred,

[0059] The first steel structure includes: a right vertical surface on the right side for fitting the vertical surface of the "┘" shaped notch, a horizontal surface at the bottom for fitting the horizontal surface of the "┘" shaped notch, and a left vertical surface on the left side for perpendicular to the left edge of the horizontal surface of the "┘" shaped notch from top to bottom.

[0060] In one embodiment,

[0061] The second steel structure includes: a left vertical surface on the left for fitting the vertical surface of the "└" shaped notch, a horizontal surface at the bottom for fitting the horizontal surface of the "└" shaped notch, and a right vertical surface on the right that runs vertically from top to bottom along the left edge of the horizontal surface of the "└" shaped notch.

[0062] In one embodiment,

[0063] The left vertical facade of the first steel structure is higher than the right vertical facade.

[0064] In one embodiment,

[0065] The right vertical facade of the second steel structure is higher than the left vertical facade.

[0066] In one embodiment,

[0067] The left vertical facade of the third structure is flush with the right vertical facade.

[0068] In one embodiment,

[0069] The left vertical facade of the first steel structure is flush with the right vertical facade of the second steel structure.

[0070] In one embodiment,

[0071] The horizontal plane of the third structure covers the left vertical face of the first steel structure and the right vertical face of the second steel structure.

[0072] In one embodiment,

[0073] The hollow sections of the first and second steel structures are each filled with elastic polyurethane.

[0074] It is understandable that after filling with elastic polyurethane, the two vertical surfaces of the third structure can be embedded in the elastic polyurethane, thereby movably abutting against the grooves of the first and second steel structures to achieve the elastic connection described above.

[0075] In one embodiment,

[0076] A fourth steel structure is provided between the left vertical face of the first steel structure and the right vertical face of the second steel structure, and the hollow part of the fourth steel structure is filled with glass wool.

[0077] In this embodiment, glass wool is filled between the stair treads and the fourth steel structure to provide insulation and noise reduction. When used for cargo transportation, it also absorbs dust.

[0078] In one embodiment,

[0079] Both the first and second steel structures consist of U-shaped steel plate grooves pre-embedded on both sides of the expansion joint, for example, U-shaped steel plate grooves with a specification of 150mm.

[0080] For example, in the first and second steel structures, the vertical surfaces that are closer to each other appear to be taller. Taking the second steel structure as an example, its left side is lower than its right side.

[0081] It should be noted that the first steel structure and the second steel structure constitute the first type of waterproof structure, which utilizes the principle of equal quantity, making it impossible for water to penetrate to the outside of the U-shaped steel plate.

[0082] In one embodiment, via Figure 2 The fourth steel structure is welded to the left vertical surface of the first steel structure and the right vertical surface of the second steel structure, respectively. Thus, the space covered below the horizontal plane of the stair tread constitutes a second type of waterproof structure. In this way, the present invention achieves multiple layers of waterproofing. Exemplarily, the fourth steel structure is made of 24# galvanized steel sheet. It is understood that the third structure of the stair tread can be made of any suitable material with appropriate strength, including but not limited to steel.

[0083] Furthermore, all welds are seamless, thus the multi-layered waterproof structure of this invention forms a fully sealed waterproof joint between the trestle and the expansion joint of the transfer station, ensuring no water leakage.

[0084] Further integration Figure 2 It can be observed that both the trestle structure and the transfer station structure can be processed into platform sections to allow the trestle structure to abut and be flush with the left vertical surface of the second steel structure, and the transfer station structure to abut and be flush with the right vertical surface of the first steel structure, thus forming a stepped structure with the stair tread structure.

[0085] Although embodiments of the present invention have been described above in conjunction with the accompanying drawings, the present invention is not limited to the specific embodiments and application fields described above. The specific embodiments described above are merely illustrative and instructive, and not restrictive. Those skilled in the art can make many other forms based on the guidance of this specification and without departing from the scope of protection of the claims of the present invention, and all of these are within the scope of protection of the present invention.
