[0069] like Figures 1 to 17 As shown, the present invention provides a cooperative expansion joint structure system of a material storage structure, which is arranged in a material storage structure (such as Fig.18 , Fig.19 , Fig. 20 shown), including,

[0070] A plurality of first expansion joint structures 1 are arranged at intervals on the low retaining wall 81 of the material storage, and include first slits 11 vertically penetrating the low retaining wall, and the vertical positions of the first slits 11 are arranged in the same manner; and the cross-section of each first slit 11 is arranged in a rectangular shape;

[0071] A plurality of second expansion joint structures 2 are arranged at intervals on the middle retaining wall 82 of the material storage, including second slits 21 penetrating the middle retaining wall, the vertical positions of the second slits 21 are arranged in the same manner, and the cross-sections of the second slits 21 are arranged in a single sawtooth shape;

[0072] A plurality of third expansion joint structures 3 are arranged at intervals between the middle platform columns 83 of the material storage, including third slits 31 penetrating the middle platform columns, the vertical positions of the third slits 31 are arranged in the same manner, the third slits 31 are arranged above the second slits 21 and are arranged penetrating with the second slits 21, and the cross section of each third slit 31 is arranged in a single sawtooth shape;

[0073] A plurality of fourth expansion joint structures 4 are arranged at intervals between the middle platform beams 84 of the material warehouse, including fourth gaps 41 between the middle platform beams, and the vertical positions of the fourth gaps 41 are arranged in the same manner;

[0074] A plurality of fifth expansion joint structures 5 are spaced apart between the middle platform plates 85 of the material storage (in the prior art, the middle platform plates support tracks, and the tracks support running vehicles), including fifth gaps 51 arranged between the middle platform plates. The vertical positions of the fifth gaps 51 are arranged in the same manner, and the cross-sections of the fifth gaps 51 are arranged in a continuously arranged serrated shape.

[0075] In the cooperative expansion joint structure system of the material storage structure provided by the present invention, different expansion joint forms are set according to the actual conditions of each component, so that the material storage structure can not only meet the free deformation of the structure along the length direction, but also realize the coordinated deformation of the material storage structure in the vertical direction and the vertical direction; the first expansion joint structure and the second expansion joint structure can ensure the cooperative work of the structure under the pressure of stacking materials while meeting the effect of temperature expansion and contraction; the third expansion joint structure, the fourth expansion joint structure and the fifth expansion joint structure can effectively adjust the deformation of the platform in the vertical and horizontal directions while meeting the effect of temperature expansion and contraction; the expansion joints of each expansion joint structure are respectively in the same vertical position, ensuring the functionality of each expansion joint structure in the present invention and the overall coordination of the structure, the structural integrity is better, the adverse effects of deformation are eliminated, the good operation of stacking materials and platform rail vehicles is met, the smooth operation of the material storage structure is ensured, and the adverse effects of temperature effects are reduced.

[0076] Further, if Figure 1 , Figure 2 , Figure 3 As shown, a first basic raft is arranged at the bottom of the first gap 11, and the two ends of the first basic raft are respectively located at the bottom of the low retaining wall on both sides of the first gap. The first gap 11 is vertically through-arranged to completely separate the low retaining wall into two left and right parts, but the left and right low retaining walls share a first basic raft, reducing the additional deformation stress caused by uneven settlement on the position of the first gap 11.

[0077] In a specific embodiment of the present invention, the width of the first gap 11 is 50 mm to 100 mm, which satisfies the expansion or contraction of the wall of the short retaining wall between the first gaps 11 under the action of temperature stress.

[0078] In a specific embodiment of the present invention, the first gap 11 is arranged in the middle of a single material grid of the material warehouse, that is, the position where the constraint effect of the horizontal partition wall 86 (existing technology) is minimal; the adjacent spacing of the first gaps 11 is not greater than 80m.

[0079] Further, if Figure 1 , Figure 2 , Figure 3 As shown, each first expansion joint structure also includes a first connecting structure, which includes a plurality of first steel bars 12 and a plurality of first steel pipes 13. Each first steel bar 12 is arranged (pre-buried) in the low retaining wall on one side of the first gap, extending from one side of the first gap to the other side. The plurality of first steel bars 12 are located at the center line position of the low retaining wall on one side of the first gap, and are arranged at equal intervals from the bottom of the wall to the top of the wall; each first steel pipe 13 is arranged (pre-buried) in the low retaining wall on the other side of the first gap, located at its center line position, and each first steel pipe 13 is arranged corresponding to each first steel bar 12, and the first steel bar 12 can be slidably passed through the first steel pipe 13.

[0080] In a specific embodiment of the present invention, the first reinforcement 12 includes vertical sections and horizontal sections, each of which is spaced 200 mm apart.

[0081] Furthermore, the diameter of each first steel bar 12 is greater than or equal to 25 mm. In a specific embodiment of the present invention, the diameter d of the first steel bar is 32 mm. The first steel pipe 13 is a stainless steel pipe with a diameter of 45 mm and a wall thickness of 3 to 5 mm.

[0082] Each first steel bar 12 is located on the short retaining wall ( Figure 4 The buried depth of the low retaining wall on the left side of the middle is greater than or equal to 35 times the diameter d of the first steel bar; the length of the low retaining wall on the side of each first steel bar 12 exposed from the first gap is greater than or equal to 15 times the diameter d of the first steel bar.

[0083] In order to facilitate the sliding of the first steel bar 12 in the first steel pipe 13, a layer of lubricating oil 7 is evenly applied to the inner wall of the first steel pipe 13. In order to prevent the lubricating oil from flowing back, the mouth of the first steel pipe 13 should be slightly higher than the bottom of the pipe by 5mm. The depth dimension of each first steel pipe 13 is greater than the length dimension of the low retaining wall on the side of each first steel bar 12 exposed from the first gap. Generally, the length of the first steel pipe 13 is not less than 15d+200mm, which is convenient for the storage of the rich lubricating oil and maintains the durability of the use of the first gap 11. Generally, the bottom of the first steel pipe 13 is pre-filled with 200mm deep lubricating oil 7.

[0084] Since the gap between the pre-buried first steel bar 12 and the first steel pipe 13 is small, the shear bearing capacity between the first steel bar 12 and the first steel pipe 13 can be used to constrain the vertical deformation difference and ensure the structural integrity of the first gap 11 of the low retaining wall of the material warehouse in resisting the stockpile pressure.

[0085] Further, if Figure 1 As shown, to prevent leakage of the internal material, each first gap 11 is filled with a first leak-proof part that can be horizontally extended. In this embodiment, the first leak-proof part is a polystyrene foam board 6, which provides a buffering effect for the extension and contraction deformation.

[0086] Further, if Figure 4 , Figure 5 As shown, a first protrusion 22 extending in the horizontal direction is provided on the intermediate retaining wall 82 on one side of the second gap 21, and a first groove 23 is provided on the intermediate retaining wall on the other side of the second gap. The first protrusion 22 can be slidably inserted into the first groove 23, and there is a gap between the side surface of the first protrusion 22 and the side surface of the first groove 23, so that the cross-section of the second gap 21 is a single sawtooth shape; a second basic raft is provided at the bottom of the second gap, and both ends of the second basic raft are respectively located at the bottom of the intermediate retaining wall on both sides of the second gap, so as to reduce the additional deformation stress brought by uneven settlement to the expansion joint position.

[0087] The second gap 21 has a gap width of 50 mm to 100 mm, which satisfies the maximum threshold of thermal expansion and contraction in the longitudinal direction (horizontal length direction) of the middle retaining wall 82 between the expansion joints under the maximum temperature difference.

[0088] Since the second gap 21 on the middle retaining wall 82 needs to bear a large material stacking thrust, the shear bearing capacity between the anchor steel bars and the embedded sleeves in the prior art is not enough to resist deformation and ensure overall coordinated deformation, and a reinforced concrete structure (first protrusion 22 and first groove 23) needs to be added to help the middle retaining wall 82 on both sides of the second gap 21 of the material warehouse work together. The first protrusion 22 is continuously arranged from the bottom of the wall to the top of the wall, and the first groove 23 is arranged corresponding to the first protrusion 22, and it is necessary to ensure that the two can be stuck together.

[0089] The second gap 21 is arranged in the middle of a single material grid of the material warehouse, that is, the position where the constraint effect of the horizontal partition wall is minimal. The spacing between adjacent second gaps 21 is not greater than 80m.

[0090] In a specific embodiment of the present invention, the dimension of the first protrusion 22 along the wall thickness direction of the middle retaining wall 82 is one third of the wall thickness, the dimension of the first protrusion 22 protruding from the middle retaining wall 82 is 300 mm, and the depth of the first groove 23 is 300+50-100 mm.

[0091] Further, if Figure 4 , Figure 5 As shown, each second expansion joint structure also includes a second connection structure, which includes a plurality of second steel bars 24 and a plurality of second steel pipes 25. Each second steel bar 24 (pre-buried) extends from the first protrusion to the first groove, and the second steel pipe 25 is arranged in the middle retaining wall on one side of the first groove, and the second steel bar 24 can be slidably penetrated in the second steel pipe 25. The plurality of second steel bars 24 are located at the center line position of the first protrusion 22, and are arranged at equal intervals from the bottom of the wall to the top of the wall; each second steel pipe 25 is arranged (pre-buried) in the middle retaining wall on one side of the first groove, located at its center line position, and each second steel pipe 25 is arranged corresponding to each second steel bar 24.

[0092] In this embodiment, the diameter of each second steel bar 24 is greater than or equal to 25 mm; the depth of each second steel tube 25 is greater than the length of each second steel bar exposed from the first protrusion. In a specific embodiment of the present invention, the depth of each second steel tube 25 is 200 mm or more greater than the length of each second steel bar exposed from the first protrusion, which is convenient for storing the rich lubricating oil. The second steel bar 24 and the first steel bar 12 can be made of the same specification steel bars, and the second steel tube 25 and the first steel tube 13 can be made of the same specification steel bars. The cooperation and function between the second steel bar 24 and the second steel tube 25 are the same as the cooperation and function between the first steel bar 12 and the first steel tube 13.

[0093] In order to protect the first protrusion 22 and the first groove 23 from being damaged when working together, a first edge protection angle steel 26 (L160×100×10mm) is buried in the relevant positive corners of the two, and lubricating oil is evenly applied on the surface to ensure free expansion and contraction under the action of temperature changes, and the shear force between the first protrusion 22 and the first groove 23 is used in the vertical direction to provide constraints to ensure the coordinated whole, so as to maintain the durability and reliability of the second gap 21 in the middle retaining wall of the material warehouse.

[0094] Furthermore, to prevent leakage of the internal material, each second gap is filled with a second leak-proof part that can be horizontally extended. In this embodiment, the second leak-proof part is a polystyrene foam board 6, which provides a buffering effect for the extension and deformation.

[0095] Further, if Figure 6 , Figure 7 As shown, a second protrusion 32 extending in the horizontal direction is provided on the middle platform column on one side of the third gap, and a second groove 33 is provided on the middle platform column on the other side of the third gap. The second protrusion 32 can be slidably inserted into the second groove 33. There are gaps between the top surface and the side surface of the second protrusion 32 and the bottom and side surface of the second groove 33 respectively, so that the cross section of the third gap 31 is a single sawtooth shape.

[0096] The gap width of the third gap 31 is between 50 mm and 100 mm, which meets the maximum threshold of thermal expansion and contraction caused by the maximum temperature difference in the longitudinal direction of the middle platform column between the expansion joints.

[0097] The third gap 31 continues the second gap 21 of the middle retaining wall. The method is the same as the second gap 21 of the middle retaining wall. The middle platform column is provided with denser stirrups and longitudinal steel bars, so it is not suitable to pre-embed steel bars and steel pipes to ensure that the bearing capacity of the structural column is not weakened. The second groove 33 is provided corresponding to the second protrusion 32, and it is necessary to ensure that the two can be stuck together to ensure free deformation and synergy.

[0098] Furthermore, each third gap 31 is filled with a third leak-proof part that can be horizontally extended and retracted. In this embodiment, the third leak-proof part is a polystyrene foam board 6, which provides a buffering effect for the expansion and contraction deformation.

[0099] Further, if Figure 8 As shown, multiple mortise and tenon structures 42 are evenly spaced between the middle platform beams 84 on both sides of the fourth gap. It provides the structure with the ability to deform freely in the horizontal and vertical directions, constrains the vertical settlement difference of the middle platform beams 84 on both sides of the fourth gap, ensures the flatness of the platform structure, and enables the upper track (in the prior art, located on the middle platform beam 84) to run smoothly.

[0100] The gap width of the fourth gap 41 is between 50 mm and 100 mm, which meets the maximum threshold of thermal expansion and contraction of the middle layer platform beam 84 between the expansion joints under the maximum temperature difference in the longitudinal direction.

[0101] Further, if Fig. 9 , Fig.10 As shown, each mortise and tenon structure includes a first mortise and tenon portion 421 and a second mortise and tenon portion 422, respectively. A plurality of first embedded parts 431 and a plurality of second embedded parts 432 are respectively preset in the middle layer platform beams on both sides of the fourth gap, and each first embedded part 431 is connected to the first mortise and tenon portion 421, and each second embedded part 432 is connected to the second mortise and tenon portion 422.
