Description

Technical Field

[0001] The invention relates to the technical field of building structures, and in particular to a material yard side wall and a material yard. Background Art

[0002] The material yard structure is generally composed of a central column, side walls, and a dome, and is usually arranged in a circular shape. Considering the combustion performance of the materials in the material yard, such as coal storage silos, there is no obvious pattern in the natural regional distribution of the coal pile. Coal in all directions along the height direction of the side wall may spontaneously combust. Therefore, a heat-insulating protective layer is often required inside the side wall along the height direction of the wall to protect the main structure of the side wall. The current insulation layer is usually in the form of a brick wall inside the concrete side wall, and the material used is refractory bricks such as hydrophobic perlite bricks.

[0003] However, for large-diameter material yards, cast-in-place concrete side walls have disadvantages such as long construction period, hydration heat generated by large-volume concrete pouring easily causing structural cracks, and being greatly affected by construction quality. If the construction quality is not properly controlled, problems such as wall tilt, inaccurate column size control, honeycombs and cracks on the surface, and leakage at construction joints will occur, affecting the safety and durability of the structure.

[0004] Building refractory brick walls inside the concrete side walls further increases the construction process and period, and the safety and durability of the refractory layer are easily affected by the construction quality of the concrete side walls. Summary of the invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the defects in the prior art that the concrete side wall with refractory brick wall has a long construction period and the refractory brick wall is easily affected by the concrete side wall in terms of safety and durability, thereby providing a material yard side wall and a material yard.

[0006] The present invention provides a material yard side wall, comprising: a plurality of plate wall structures, which are arranged in a metal structure and in a ring shape; a plurality of columns, which are arranged vertically and correspondingly between adjacent plate wall structures and are suitable for connecting the plate wall structures; and a plurality of prefabricated heat insulation panels, which are connected to the plate wall structures and are distributed along one surface thereof facing the inner side of the enclosed unit.

[0007] The plate wall structure is arranged in the form of corrugated metal plates, and the corrugations thereon are arranged vertically.

[0008] The material yard side wall also includes: a plurality of ring beam structures, which are correspondingly arranged on the plate wall structure along the ring direction and distributed along the height direction, and are connected to the columns on the adjacent two sides of the plate wall structure.

[0009] The distribution density of the ring beam structure gradually decreases along the upward height direction.

[0010] The material yard side wall also includes: a plurality of dense rib columns extending in the vertical direction and spaced apart from each other, wherein the dense rib columns are arranged between adjacent ring beam structures, and the adjacent ring beam structures sandwiching the dense rib columns are at least distributed on the lower side of the plate wall structure.

[0011] The prefabricated heat-insulating panel is a prefabricated concrete trough panel, and a reserved embedded part is arranged on the side facing the panel wall structure, which is suitable for connecting with the panel wall structure.

[0012] A support weld plate is also provided on the top of the column, which is suitable for supporting the top grid.

[0013] The top of the column faces the inner side of the unit formed by the plate wall structure, and a triangular support frame is extended and arranged. The triangular support frame is extended in a circumferential direction and is suitable for carrying maintenance personnel.

[0014] At least the column and the ring beam structure are provided as steel structures.

[0015] The present invention provides a material yard, comprising: the material yard side wall mentioned above;

[0016] The top grid is provided in a metal structure and is connected to the top side of the side wall of the material yard;

[0017] The concrete foundation is arranged at the lower side of the material yard side wall and is suitable for supporting the column of the material yard side wall.

[0018] The column also includes a bearing portion, which is connected and arranged on the bottom of the column;

[0019] The concrete foundation comprises a base and a receiving groove arranged on the base, wherein the receiving groove is suitable for receiving the bearing part and is filled with post-cast concrete.

[0020] The base includes a plurality of prefabricated concrete structures, which are distributed in a circumferential direction and connected to each other. The technical solution of the present invention has the following advantages:

[0021] 1. A material yard side wall, characterized in that it comprises: a plurality of plate wall structures, which are arranged in a metal structure and are arranged in a ring shape; a plurality of columns, which are arranged vertically between adjacent plate wall structures and are suitable for connecting the plate wall structures; a plurality of prefabricated insulation panels, which are connected to the plate wall structures and are distributed along one side thereof facing the inner side of the enclosed unit.

[0022] By setting the plate wall structure as a metal component and cooperating with the column, the installation and construction can be carried out through a modular structure, which is simple and easy, with a short construction period, less impact on construction quality, high safety and durability, no need for pouring, reducing the steps of pouring concrete on site, reducing on-site construction processes, further shortening the construction period and saving energy consumption;

[0023] At the same time, prefabricated insulation panels are arranged on the board wall structure, and the prefabricated insulation panels are arranged as prefabricated parts. On the one hand, the board wall structure as a metal component has high strength and stable structure, and as a modular structure, it is less affected by the construction quality. Therefore, as the installation basis of the prefabricated insulation panels, the safety and durability of the prefabricated insulation panels are further guaranteed; on the other hand, the prefabricated insulation panels themselves are prefabricated parts and can be prefabricated in advance, which shortens the construction period of on-site installation. Combined with the board wall structure of metal components, the construction period of the side wall of the material yard is further reduced. This arrangement effectively overcomes the defects of the prior art that the concrete side wall with refractory brick walls has a long construction period, and the refractory brick walls are easily affected by the concrete side walls, which affect the safety and durability.

[0024] 2. The material yard side wall provided by the present invention has a plate wall structure of a corrugated metal plate, and the corrugations thereon are arranged vertically.

[0025] At present, in the prior art, the side wall of the material yard bears not only the coal pile load, but also the temperature load. The former will cause the side wall to bear the out-of-plane (radial) pressure, and the latter will cause the side wall to bear the circumferential tensile pressure.

[0026] In the prior art, the side wall structure of the material yard generally adopts structures such as slab walls and buttresses formed by cast-in-place concrete. For large-diameter circular material yards, the cast-in-place concrete side walls have the disadvantages of long construction period, hydration heat generated by pouring large-volume concrete easily causing structural cracks, large consumption of scaffolding and formwork, and great influence of construction quality. If the construction quality is not properly controlled, problems such as wall tilt, inaccurate size control of wedge-shaped buttresses, honeycombs and cracks on the surface, and leakage at construction joints will occur, affecting the safety and durability of the structure.

[0027] In addition, in the prior art, the side wall structure of the material yard can also adopt non-reinforced steel plate walls or reinforced steel plate walls. The non-reinforced steel plate walls can be divided into thick steel plate walls and thin steel plate walls based on the width-to-thickness ratio of the embedded wall panels. Among them, the thick steel plate wall system has a large initial stiffness and good out-of-plane stability, but the amount of consumables is large, while the thin steel plate wall has a large initial stiffness, and the system has a high lateral bearing capacity after the tensile field effect of the embedded wall panels is exerted, but the out-of-plane stability is low; the setting of stiffening ribs in the reinforced steel plate wall system can improve its out-of-plane stability, but the welding construction is cumbersome and the residual stress after welding has a serious impact, which reduces the bearing stability of the reinforced steel plate wall.

[0028] By setting the plate wall structure as a corrugated metal plate, the geometric undulation structure of the corrugated metal plate can play the role of a stiffening rib of a stiffened steel plate, improve the out-of-plane stability of the corrugated steel plate shear wall, and effectively suppress the out-of-plane buckling of the steel plate under load. At the same time, the special undulation structure of the corrugated steel plate makes it have a smaller compressive stiffness in the direction of the corrugation, that is, the direction of wave propagation, and has a much larger compressive stiffness in the direction perpendicular to the corrugation than the non-stiffened wall panel of the same thickness. For the corrugated metal plate with vertically arranged corrugations, its axial compressive stiffness is greater than that of the non-stiffened wall panel. At the same time, the corrugated metal plate and the column jointly bear the gravity load, effectively improving the out-of-plane stiffness and preventing the occurrence of buckling when the gravity load acts. Therefore, the "accordion effect" makes the corrugated metal plate have the mechanical properties of a stiffened steel plate, and effectively avoids the residual stress generated during the welding of the stiffening ribs, and has the advantages of good out-of-plane stability, large initial stiffness, good ductility and high shear bearing capacity.

[0029] 3. The material yard side wall provided by the present invention also includes: a plurality of ring beam structures, which are correspondingly arranged on the plate wall structure along the ring direction and distributed along the height direction, and are connected to the columns on the adjacent two sides of the plate wall structure.

[0030] The arrangement of the ring beam structure on the plate wall structure can increase the strength of the plate wall structure, further improve the bearing capacity of the plate wall structure for the hoop tensile stress, and improve the stability of the plate wall structure.

[0031] 4. In the material yard side wall provided by the present invention, the distribution density of the ring beam structure gradually decreases along the upward height direction.

[0032] The side walls of the material yard bear the coal pile load and temperature load respectively, and the load size will gradually increase with decreasing height. By setting the ring beam structure along the upward height direction, the distribution density gradually decreases. The ring beam structure with higher density can be concentrated on the side walls of the material yard at a lower height, which can further increase the bearing capacity and stability of the side walls of the material yard.

[0033] 5. The material yard side wall provided by the present invention comprises a plurality of dense-ribbed columns extending in the vertical direction and spaced apart from each other. The dense-ribbed columns are arranged between adjacent ring beam structures, and the adjacent ring beam structures sandwiching the dense-ribbed columns are at least distributed on the lower side of the plate wall structure.

[0034] By arranging dense rib columns between adjacent ring beam structures on the lower side of the plate wall structure and combining the ring beam structure, the bearing capacity and stability of the side wall of the material yard at a lower height can be further increased.

[0047] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0048] like Figure 1-Figure 6 As shown, this embodiment provides a material yard side wall, including: a plurality of plate wall structures 1, a plurality of columns 2 and a plurality of prefabricated insulation panels 3.

[0049] The plate wall structure 1 is arranged in an arc-shaped plate shape, and can also be arranged in a flat plate shape. Several plate wall structures 1 are arranged in a ring shape. The specific shape of the side wall of the material yard is not limited. It can be surrounded by the plate wall structure 1 as needed, and can be circular or square, etc. In the present embodiment, the side wall of the material yard is arranged in a circular ring structure, and each plate wall structure 1 is arranged in a circular ring shape, and the arc surface of one side of each plate wall structure 1 is arranged toward the center of the ring. Specifically, the plate wall structure 1 is a metal component, specifically a steel component, or other alloys, and is installed in a modular manner. It can be a non-reinforced steel plate wall, a reinforced steel plate wall, etc. In the present embodiment, the plate wall structure 1 is a corrugated metal plate.

[0050] The column 2 is arranged vertically, and its bottom end is buried below the floor elevation 10, and can also be supported by a load-bearing platform. The column 2 is correspondingly arranged between adjacent plate wall structures 1, or at the position of overlapping plate wall structures 1, and can be connected to adjacent plate wall structures 1 by detachable connecting parts, such as screws, channel steel parts, angle steel parts and other structures. In this embodiment, as a preferred embodiment, the column 2 is a lattice column, and further, a metal lattice column. As a convertible embodiment, the column 2 is a single column, and can also be a concrete column. As a convertible embodiment, the column 2 and the plate wall structure 1 can also be connected by welding or other methods.

[0051] The prefabricated heat insulation board 3 is provided in the form of an arc-shaped board or a flat board, matched with and connected to the board wall structure 1, and distributed along one surface of the board wall structure 1 facing the inner side of the enclosed annular unit.

[0052] By setting the plate wall structure 1 as a metal component, in conjunction with the column 2, the installation and construction can be carried out through a modular structure, which is simple and easy, has a short construction period, is less affected by the construction quality, has high safety and durability, does not require pouring, reduces the steps of pouring concrete on site, reduces the on-site construction process, further shortens the construction period, and saves energy consumption;

[0053] At the same time, a prefabricated insulation board 3 is arranged on the board wall structure 1, and the prefabricated insulation board 3 is arranged as a prefabricated part. On the one hand, the board wall structure 1 as a metal component has high strength and stable structure, and as a modular structure, it is less affected by the construction quality. Therefore, as the installation basis of the prefabricated insulation board 3, the safety and durability of the prefabricated insulation board 3 are further guaranteed; on the other hand, the prefabricated insulation board 3 itself is a prefabricated part, which can be prefabricated in advance, shortening the construction period of the on-site installation. Combined with the board wall structure 1 as a metal component, the construction period of the material yard side wall is further reduced. This arrangement effectively overcomes the defects of the prior art that the concrete side wall with a refractory brick wall has a long construction period, and the refractory brick wall is easily affected by the concrete side wall. The safety and durability.

[0054] In this embodiment, the plate wall structure 1 is provided in the form of a corrugated metal plate, and the corrugations thereon are arranged vertically.

[0055] At present, in the prior art, the side wall of the material yard bears not only the coal pile load but also the temperature load. The former will cause the side wall to bear the out-of-plane radial pressure, and the latter will cause the side wall to bear the circumferential tensile pressure.

[0056] In the prior art, the side wall structure of the material yard generally adopts structures such as slab walls and buttresses formed by cast-in-place concrete. For large-diameter circular material yards, the cast-in-place concrete side walls have the disadvantages of long construction period, hydration heat generated by pouring large-volume concrete easily causing structural cracks, large consumption of scaffolding and formwork, and great influence of construction quality. If the construction quality is not properly controlled, problems such as wall tilt, inaccurate size control of wedge-shaped buttresses, honeycombs and cracks on the surface, and leakage at construction joints will occur, affecting the safety and durability of the structure.

[0057] In addition, the side wall structure of the material yard can also adopt non-reinforced steel plate wall or reinforced steel plate wall. The non-reinforced steel plate wall can be divided into thick steel plate wall and thin steel plate wall according to the width-to-thickness ratio of the embedded wall panel. Among them, the thick steel plate wall system has a large initial stiffness and good out-of-plane stability, but the material consumption is large, while the thin steel plate wall has a large initial stiffness, and the system's lateral bearing capacity is high after the tensile field effect of the embedded wall panel is exerted, but the out-of-plane stability is low; the setting of stiffening ribs in the reinforced steel plate wall system can improve its out-of-plane stability, but the welding construction is cumbersome and the residual stress after welding has a serious impact, which reduces the bearing stability of the reinforced steel plate wall.

[0058] By setting the plate wall structure 1 as a corrugated metal plate, the geometric undulation structure of the corrugated metal plate can play the role of a stiffening rib of a stiffened steel plate, thereby improving the out-of-plane stability of the corrugated steel plate shear wall and effectively suppressing the out-of-plane buckling of the steel plate under load. At the same time, the special undulation structure of the corrugated steel plate enables it to have a smaller compressive stiffness in the direction of the corrugation, that is, the direction of wave propagation, and has a much larger compressive stiffness in the direction perpendicular to the corrugation than the non-stiffened wall panels of the same thickness. For the corrugated metal plate with vertically arranged corrugations, its axial compressive stiffness is greater than that of the non-stiffened wall panels. At the same time, the corrugated metal plate and the column 2 jointly bear the gravity load, effectively improving the out-of-plane stiffness and preventing the occurrence of buckling when the gravity load acts. Therefore, the "accordion effect" makes the corrugated metal plate have the mechanical properties of a stiffened steel plate, and effectively avoids the residual stress generated when the stiffening ribs are welded, and has the advantages of good out-of-plane stability, large initial stiffness, good ductility and high shear bearing capacity.

[0059] The side wall of the material yard also includes a plurality of ring beam structures 4, which are correspondingly arranged on the plate wall structure 1 along the ring direction and distributed along the height direction, and are connected to the columns 2 on both sides adjacent to the plate wall structure 1.

[0060] Each ring beam structure 4 is correspondingly arranged on the side of the board wall structure 1 away from the center of the material yard side wall along the circumferential direction, and is arranged at intervals along the height direction. The ring beam structure 4 is detachably connected to the columns 2 on the adjacent sides of the board wall structure 1 through connecting parts such as screws. The arrangement of the ring beam structure 4 on the board wall structure 1 can increase the strength of the board wall structure 1, further improve the bearing capacity of the board wall structure 1 for circumferential tensile stress, and improve the stability of the board wall structure 1. As a convertible embodiment, the ring beam structure 4 can be arranged on the side of the board wall structure 1 close to the center of the material yard side wall.

[0061] Furthermore, the ring beam structure 4 has a gradually decreasing distribution density along the upward height direction. The side walls of the material yard bear the coal pile load and the temperature load respectively, and the load size will gradually increase as the height decreases. By setting the ring beam structure 4 to have a gradually decreasing distribution density along the upward height direction, the ring beam structure 4 with a higher density can be concentratedly distributed on the material yard side walls at a lower height position, which can further increase the bearing capacity and stability of the material yard side walls.

[0062] The material yard side wall also includes a plurality of dense ribbed columns 5. In this embodiment, the dense ribbed columns 5 are arranged in a long strip shape and extend in the vertical direction. Each dense ribbed column 5 is spaced apart from each other. As a transformable implementation, the dense ribbed columns 5 can also be arranged in a cross, inclined or grid shape. Further, the dense ribbed columns 5 are arranged between some adjacent ring beam structures 4 and connected to the ring beam structures 4. Specifically, in this embodiment, the dense ribbed columns 5 are arranged only between the two ring beam structures 4 at the bottom of the material yard side wall. As a transformable implementation, the dense ribbed columns 5 can be arranged between the ring beam structures 4 at the upper side, or the ring beam structures 4 sandwiched with dense ribbed columns 5 can be arranged at intervals.

[0063] In this embodiment, the prefabricated heat insulation board 3 is specifically a concrete prefabricated groove board, and the side thereof facing the board wall structure 1 is provided with a concave-convex structure matching the shape of the board wall structure 1, and a reserved embedded part is also provided thereon, specifically, embedded bolts, or steel plates and anchor bars, etc., suitable for connecting the board wall structure 1.

As a convertible embodiment, the prefabricated heat insulation board 3 can also be other prefabricated asbestos heat insulation boards, prefabricated mineral wool heat insulation boards, or prefabricated high temperature and high pressure resistant resin heat insulation boards, etc.

[0064] A support weld plate 6 is also provided on the top of the column 2. The support weld plate 6 is provided in the form of a flat steel plate and is suitable for bearing and connecting the top grid 8. As a convertible embodiment, a support beam can be provided between adjacent columns 2 to support the top grid 8.

[0065] In this embodiment, the top of the column 2 is extended toward the inner side of the unit formed by the panel wall structure 1, and a triangular frame 7 is extended. The triangular frame 7 is extended in the circumferential direction and is suitable for carrying maintenance personnel. Furthermore, a grid plate or a patterned steel plate or other structures can be laid on the triangular frame 7. As a convertible embodiment, the triangular frame 7 can be extended to the outer side of the unit formed by the panel wall structure 1. As another convertible embodiment, the triangular frame 7 can also be a flat plate structure or a grid structure, etc., which can meet the needs of carrying maintenance personnel.

[0066] Furthermore, the column 2 and the ring beam structure 4 are both steel structures. In addition, in this embodiment, the support weld plate 6, the multi-rib column 5, the support weld plate 6 and the triangular support frame 7 are all steel structures. In this way, the side wall of the material yard can be set as a steel structure as a whole, which can effectively replace the cast-in-place concrete structure. There is no need to support the concrete formwork on site, which is convenient for installation, significantly shortens the construction period, reduces the amount of concrete used, and solves the quality problems caused by the hydration heat of large-volume concrete pouring.

[0067] This embodiment also provides a material yard, comprising: the material yard side wall, the top grid 8 and the concrete foundation 9. The top grid 8 is a dome-shaped metal grid structure, which is buckled and arranged on the top side of the material yard side wall and fixedly connected with each support welding plate 6 on the material yard side wall. The concrete foundation 9 is arranged on the lower side of the material yard side wall, suitable for supporting the column 2 of the material yard side wall. The concrete foundation 9 is arranged on the lower side of the material yard side wall, suitable for supporting the column 2 of the material yard side wall.

[0068] Furthermore, the column 2 also includes a bearing portion 21, which is in the shape of a horizontal plate and is connected to the bottom of the column 2. In addition, in this embodiment, connection reinforcement ribs are also provided around the connection position between the column 2 and the bearing portion 21, which can increase the self-strength and connection strength of the column 2 and the bearing portion 21, improve the load capacity of the bearing portion 21, and at the same time increase the connection area with the concrete foundation 9 to improve the connection tightness.

[0069] In addition, the concrete foundation 9 includes a base 91 and a receiving groove 92 arranged on the base 91. The top of the base 91 is higher than the floor elevation 10. The receiving groove 92 can accommodate the bearing part 21 and the column 2, and is filled with post-cast concrete 93 to achieve stable installation of the bearing part 21.

[0070] In this embodiment, the base 91 includes a plurality of precast concrete structures, which are prefabricated concrete block structures, which are arranged in segments along the annular direction and are evenly distributed. Adjacent precast concrete structures are welded by steel bars in the foundation or the steel bars are mechanically connected through structures such as connecting joints, and post-cast strips are provided for post-casting of concrete.

[0071] As a convertible embodiment, the base 91 may also be a cast-in-place concrete pile foundation structure.

[0072] Obviously, the above embodiments are merely examples for clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the protection scope of the invention.
