Description

Technical Field

[0001] The utility model relates to the field of construction, in particular to a connecting piece between an H-shaped column and a square steel column of a cold storage steel structure warehouse. Background Technique

[0002] With the development and growth of the logistics industry, the functions of many traditional warehouses are increasingly unable to meet the high-speed development of the logistics industry. Due to the advantages of short construction period, light self-weight, good seismic performance, low comprehensive cost, environmental protection, etc. of steel structures, steel structure warehouses are replacing traditional warehouses and becoming the main structure of logistics warehousing. H-shaped columns and square steel columns are often used in common steel structure buildings. The two types of steel have different advantages. The square steel column has better load-bearing performance than the H-shaped column, and the steel structure building is more stable and safe; the H-shaped column is more material-saving than the square steel column, and the construction cost of the steel structure building is lower.

[0003] With the rapid development of the cold chain logistics industry, more and more cold chain logistics projects are being built. Compared with conventional ordinary warehouses, cold storage steel structure warehouses have higher requirements for load-bearing performance due to the necessity of refrigeration equipment such as refrigeration fans and the stacking of goods layer by layer. Moreover, most cold storage warehouses will be designed to be taller and larger considering the economy of goods storage and the upper equipment pipelines. For the construction operation of cold storage steel structure warehouses, if the steel structure frame completely uses H-shaped columns, the load-bearing effect may be insufficient and it cannot provide the load-bearing capacity to support a large number of refrigeration equipment. If square steel columns are completely used, the steel consumption will be too large and the construction cost will increase. Summary of the Invention

[0004] In view of this, the purpose of the utility model is to provide a connecting piece between an H-shaped column and a square steel column of a cold storage steel structure warehouse with a square steel column at the bottom and an H-shaped column at the top, taking into account safety and economy.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is a connecting piece between an H-shaped column and a square steel column of a cold storage steel structure warehouse, including a bottom plate and a first plate body and a second plate body fixedly spaced above the bottom plate. The first plate body and the second plate body are fixedly connected by a support plate, and a first stiffening rib plate is fixedly arranged vertically above the support plate.

[0006] The beneficial effects of the above technical solution are: The whole connecting piece can be applied to the connection position where a square steel column is lapped at the bottom and an H-shaped column is at the top. The distance between the first plate body and the second plate body is maintained by the support plate, thereby enhancing the stability and load-bearing capacity. Moreover, the connecting piece can be fabricated and installed by means of prefabricated welding, effectively reducing the construction difficulty, saving construction time, and realizing the connection between the square steel column frame at the bottom and the H-shaped column steel frame structure at the top of the cold storage steel structure warehouse. The use of square steel columns for the bottom steel frame ensures the stability and load-bearing capacity of the cold storage steel structure warehouse, and the upper H-shaped column steel frame structure can save steel frame materials and reduce costs.

[0007] Furthermore, the support plate is horizontally arranged, and a second stiffening rib plate is vertically fixed below the support plate. The first stiffening rib plate and the second stiffening rib plate are perpendicular to each other.

[0008] Beneficial effects: Further enhance the stability and load-bearing capacity of the connecting piece. The upper first stiffening rib plate and the lower second stiffening rib plate are perpendicular to each other, maximizing the bending resistance performance.

[0009] Furthermore, the bottom plate is fixed at the top of the square steel column. The top end of the first plate body is fixed at the bottom of one flange of the H-shaped column, and the top end of the second plate body is fixed at the bottom of the other flange of the H-shaped column. The first stiffening rib plate is fixedly connected to the web of the H-shaped column.

[0010] Beneficial effects: Provide a connection method for the connecting piece to be applied at the connection node of the H-shaped column and the square steel column, effectively ensuring the welding operation surface, and facilitating welding and fixing at the connection part.

[0011] Furthermore, the first stiffening rib plate is in the same direction as the web of the H-shaped column and the connection parts are fitted properly. The left and right sides of the first stiffening rib plate are respectively fixedly connected to the first plate body and the second plate body and the connection parts are fitted properly.

[0012] Beneficial effects: The upper part of the first stiffening rib plate is fixedly connected to the web of the H-shaped column, the lower part is fixedly connected to the support plate, and the left and right sides are respectively fixedly connected to the first plate body and the second plate body. All the connection parts are fitted properly to ensure that the connection between the H-shaped column and the connecting piece as a whole is tight without gaps, further enhancing the force-bearing stability of the connecting piece.

[0013] Furthermore, a fixing piece is added at the connection between the first stiffening rib plate and the web of the H-shaped column to strengthen the connection.

[0014] Beneficial effects: Reinforce the connection between the first stiffening rib plate and the web of the H-shaped column.

[0015] Furthermore, the fixing piece includes a connecting plate, high-strength bolts and nuts. One side of the connecting plate has through holes corresponding to the positions where the first stiffening rib plate is opened. The high-strength bolts pass through the through holes and are locked with the nuts. The other side of the connecting plate has through holes corresponding to the positions where the web of the H-shaped column is opened. The high-strength bolts pass through the through holes and are locked with the nuts.

[0016] Beneficial effects: After the high-strength bolts and nuts are threadedly connected, the connecting plate becomes the carrier for the common connection of the first stiffening rib plate and the web of the H-shaped column.

[0017] Furthermore, at least one of the first plate body and the second plate body is perpendicular to the bottom plate.

[0018] Beneficial effects: On the one hand, the structure on the perpendicular side has better vertical load-bearing effect. On the other hand, it is also beneficial to the processing and installation of the connecting piece. Description of the Drawings

[0024] As Figures 1 - 3 shown, a connecting member between an H-shaped column and a square steel column of a cold-chain steel structure warehouse of the present utility model includes a bottom plate 1 and a first plate body 2 and a second plate body 3 that are fixedly spaced above the bottom plate. The first plate body 2 and the second plate body 3 are fixedly connected by a support plate 4. Above the support plate 4, a first stiffening rib plate 5 is fixedly arranged vertically. The support plate 4 is used to maintain the distance between the first plate body 2 and the second plate body 3 and prevent the first plate body 2 and the second plate body 3 from deforming under force; the support plate 4 is horizontally arranged, and a second stiffening rib plate 6 is fixedly arranged vertically below the support plate 4. The first stiffening rib plate 5 and the second stiffening rib plate 6 are perpendicular to each other, further enhancing the stability and load-bearing capacity of the connecting member and maximizing the bending resistance performance. When applied to the connection node where the H-shaped column 11 overlaps above the square steel column 12, it can realize the connection of the H-shaped column steel frame structure above the square steel column frame at the bottom of the cold-chain steel structure warehouse.

[0025] During the application of this embodiment, the bottom plate 1 is fixed to the top of the square steel column 12, the top end of the first plate body 2 is fixed to the bottom of one flange 101 of the H-shaped column 11, and the top end of the second plate body 3 is fixed to the bottom of the other flange 101 of the H-shaped column 11. The first stiffening rib plate 5 is fixedly connected to the web 102 of the H-shaped column, providing a connection method for the connector to be applied at the connection node of the H-shaped column 11 and the square steel column 12, and the connection part is convenient for welding and fixing. Specifically, the first stiffening rib plate 5 is in the same direction as the web 102 of the H-shaped column 11 and the connection parts are fitted. The left and right sides of the first stiffening rib plate 5 are respectively fixedly connected to the first plate body 2 and the second plate body 3 and the connection parts are fitted. The first stiffening rib plate 5 is a filling plate, the upper part is fixedly connected to the web 102 of the H-shaped column, the lower part is fixedly connected to the support plate 5, and the left and right sides are respectively fixedly connected to the first plate body 2 and the second plate body 3. All the connection parts are fitted to ensure that the connection between the H-shaped column 11 and the connector is tight without gaps, further enhancing the force-bearing stability of the connector and ensuring the quality and safety of the cold-chain steel structure warehouse.

[0026] In this embodiment, a fixing piece is added at the connection between the first stiffening rib plate 5 and the web 102 of the H-shaped column to strengthen the connection.
