Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a waterproof structure of a deformation joint at an interface of a coal conveying trestle. Background Art

[0002] The coal handling trestle in a coal-fired power plant is a structure that connects various transfer stations and is used for fuel transportation. Deformation joints are often set at the interface between the coal handling trestle and the transfer station floor. This is a structural joint reserved for deformation caused by external factors such as temperature changes, uneven foundation settlement, and earthquakes.

[0003] Since the pier and transfer station will flush the floor during production operation, the flushing water containing coal powder can easily flow out through the expansion joints, thereby contaminating the exterior facade of the transfer station.

[0004] To this end, the present application specifically proposes a waterproof structure of the deformation joint at the interface of the coal conveyor trestle to solve the above-mentioned technical problems, and the above-mentioned content is only used to assist in understanding the technical solution of the present application, and does not represent an admission that the above-mentioned content is the closest prior art. Utility Model Content

[0005] The main purpose of the utility model is to provide a waterproof structure for the deformation joints at the interfaces of coal conveying trestles, which can protect the materials at the deformation joints, extend the service life of the materials, reduce the possibility of flushing water carrying coal powder leaking from the deformation joints, and avoid the external facade of the transfer station being polluted by the leaking water. At the same time, the waterproof structure proposed in the utility model of the present application can also be applied to the deformation joints set in the middle of over-long trestles, the interfaces of various pipe galleries in other industrial buildings, and the floors where water is used but deformation joints must be set.

[0006] In order to solve the above-mentioned technical problems, the utility model provides a waterproof structure of the deformation joint at the interface of the coal conveying trestle, including a waterproof structure main body, which is arranged at the deformation joint main body formed between the trestle main body and the transfer station main body, and the waterproof structure main body includes two groups of flange structures with different heights respectively arranged on the close sides of the trestle main body and the transfer station main body, and the higher group of the flange structures is provided with an ear structure, and the ear structure is used to cooperate with the other group of the flange structures to form a side opening.

[0007] Furthermore, a U-shaped main waterproof layer is arranged in the side opening, and the inner side of the main waterproof layer is filled with a blocking material.

[0008] Furthermore, the ear structure extends over another group of the flange structures, and a drip structure is provided at the end of the flange structure.

[0009] Furthermore, the indoor floor of the pier body is provided with a pier floor surface layer, and the indoor floor of the transfer station body is provided with a waterproof floor surface layer.

[0010] Furthermore, the bottom end of the main waterproof layer is fitted with a flange structure and extends into the surface layer of the pier floor or the surface layer of the waterproof floor.

[0011] Furthermore, an additional waterproof layer is provided in the surface layer of the pier floor and the surface layer of the waterproof floor, and one end of the additional waterproof layer is in contact with the outer surface of the flange structure.

[0012] Furthermore, the indoor floor of the main body of the transfer station is provided with a slope, and a floor drain is provided at the lowest point of the indoor floor surface of the main body of the transfer station.

[0013] Furthermore, a plain concrete step is arranged on the side away from the flange structure.

[0014] The beneficial effects of the utility model are embodied in:

[0015] 1. The waterproof structure body of the utility model is located at the main body of the expansion joint. By arranging a flange structure and a pick ear structure, and cooperating to form a side opening, the position of the expansion joint is converted from the front to the side, which can reduce the scouring of the expansion joint by the flushing water carrying coal powder and the trampling of people on the expansion joint, thereby further reducing the damage to the material at the expansion joint structure caused by the scouring of the flushing water carrying coal powder and the trampling of people, thereby extending the service life of the expansion joint structure. At the same time, it has stronger applicability and stronger fault tolerance for extensive construction.

[0016] 2. The utility model sets a U-shaped main waterproof layer in the side opening and fills the U-shaped part of the main waterproof layer with sealing materials. This can not only protect the materials at the deformation joints and extend the service life of the materials, but also reduce the possibility of flushing water carrying coal powder leaking from the deformation joints, thereby avoiding contamination of the exterior facade of the transfer station by leaking water.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0027] In the comparative example, see Figure 4 and Figure 5 .

[0028] like Figure 4 As shown, in the prior art, the trestle body 1 and the transfer station body 2 are simply spliced ​​when connected. In addition, according to the national standard atlas "Deformation Joint Building Structure" (numbered 14J936), there are various structural measures for floor deformation joints, such as Figure 5 As shown in the figure, the waterproof structural measures at the interface between the existing coal conveyor trestle and the transfer station floor are generally welded firmly between the coal conveyor trestle and the transfer station with a 5-thick steel plate and a pad iron plate, and turned up at the step to connect with the step steel plate, and waterproof mortar is used at the gap for caulking. Therefore, there are the following disadvantages in actual use:

[0029] 1. The flushing water containing coal powder is corrosive to a certain extent. If it directly contacts the metal cover of the expansion joint for a long time, it is easy to cause serious damage to the durability of the material.

[0030] 2. When inspectors walk between the trestle and the transfer station, their shoes will be covered with coal dust. Frequent trampling on the deformation joints can easily damage the materials at the nodes and cause the structure to loosen.

[0031] 3. Due to the characteristics of the material, careless construction and long-term trampling of personnel, the aging and damage of the sealant are very serious.

[0032] The above problems will weaken the structural protection capacity of the expansion joints, and then cause leakage problems at the interfaces, polluting the building facades.

[0033] In the embodiment, see Figures 1 to 3 .

[0034] like Figures 1 to 3 As shown, in order to solve the existing technical problems in the comparative example, the utility model provides a waterproof structure of the deformation joint at the interface of the coal conveying trestle, including a waterproof structure body 4, which is arranged at the deformation joint body 3 formed between the trestle body 1 and the transfer station body 2, and the waterproof structure body 4 includes two groups of flange structures 41 with different heights respectively arranged on the side close to the trestle body 1 and the transfer station body 2, and the higher group of flange structures 41 is also provided with a pick ear structure 42, and the pick ear structure 42 is used to cooperate with the other group of flange structures 41 to form a side opening, so that the position of the deformation joint can be converted from the front upward to the side, reducing the scouring of the deformation joint by flushing water carrying coal powder and the trampling of people on the deformation joint, so as to further reduce the damage to the material at the deformation joint structure caused by the scouring of flushing water carrying coal powder and the trampling of people, thereby extending the service life of the deformation joint structure, and at the same time, it has stronger applicability and stronger fault tolerance for extensive construction.

[0035] Specifically, a U-shaped main waterproof layer 43 is also set up in the side opening, and the inner side of the U-shaped part of the main waterproof layer 43 is filled with a sealing material 44. By using the sealing material 44 to fill the U-shaped part of the main waterproof layer 43, it can not only protect the materials at the deformation joints and extend the service life of the materials, but also reduce the possibility of flushing water carrying coal powder leaking from the deformation joints, thereby avoiding the pollution of the outer facade of the transfer station by leaking water.

[0036] In addition, it should be noted that when this structure is actually used, in order to meet the needs of waterproofing, the height of the flange structure 41 should be appropriately increased. However, since a coal conveyor belt needs to be installed on the floor, the distance from the bottom surface of the coal conveyor belt to the building floor is affected by the process. Therefore, the height of the flange needs to be appropriately adjusted taking into account the needs of waterproofing and process, that is, the height of the raised ear should not hinder the smooth operation of the coal conveyor belt in the trestle.

[0037] In a specific embodiment, the ear structure 42 extends over another set of flange structures 41 , and a drip structure 46 is disposed at the end of the flange structure 41 to prevent rainwater from flowing along the bottom surface of the ear structure 42 into the deformation joint body 3 .

[0038] In a specific embodiment, the indoor floor of the pier body 1 is provided with a pier floor surface layer 11 , and the indoor floor of the transfer station body 2 is provided with a waterproof floor surface layer 21 .

[0039] At this time, the bottom end of the main waterproof layer 43 is in contact with the flange structure 41 and extends into the pier floor surface layer 11 or the waterproof floor surface layer 21 .

[0040] Furthermore, one end of an additional waterproof layer 45 is provided in the pier floor surface layer 11 and the waterproof floor surface layer 21 , and one end of the additional waterproof layer 45 is in contact with the outer surface of the flange structure 41 .

[0041] Specifically, when the additional waterproof layer 45 is attached to the longer flange structure 41, the additional waterproof layer 45 is an L-shaped structure, and the top end extends to the top of the side wall of the flange structure 41. When the additional waterproof layer 45 is attached to the shorter flange structure 41, the additional waterproof layer 45 is a Z-shaped structure, and the top end extends to the other end of the top surface of the flange structure 41.

[0042] The cooperation between the main waterproof layer 43 and the additional waterproof layer 45 can greatly improve the water-proof effect of the flange structure 41 and avoid water leakage on the floor.

[0043] In a specific embodiment, the indoor floor surface of the transfer station body 2 maintains a certain slope, and floor drains 6 or drainage ditches are provided at the lowest points of the indoor floor surface of the transfer station body 2 and the indoor floor surface of the pier body 1 to reduce the chance of flushing water crossing the deformation joint, and the floor drains 6 or drainage ditches on the floor of the transfer station body 2 should be set at a position away from the deformation joint, thereby reducing the residence time of the flushing water on the transfer station floor at the deformation joint.

[0044] In addition, it needs to be further explained that a water collection tank should be set up at the bottom of the ground area corresponding to the pier or the transfer station, so that the flushing water in the pier or transfer station can enter the pre-sedimentation tank in the water collection tank through the floor drain 6 or the drainage ditch, and then be discharged after preliminary treatment.

[0045] In a specific embodiment, a plain concrete step 5 is provided on the side away from the flange structure 41, which is combined with the drainage design of the overall structure to solve the height difference between the ear (42) and the floor. It is not only beautiful but also easy to walk on and reduces the risk of tripping.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

[0047] In addition, it should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0048] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing in the full text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or schemes that A and B meet at the same time. In addition, in the embodiments of the utility model, "multiple" refers to more than two. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.
