Description

Technical Field

[0001] The utility model belongs to the field of container building construction, and in particular relates to a connection node used for low-rise container buildings. Background Art

[0002] With the development of global trade and the popularity of container transportation, container buildings are increasingly used in the construction field. Container buildings have gradually become an important form of construction due to their modularity, fast construction speed and low cost. However, the connection node problem of container buildings has always been one of the key factors affecting their structural safety and stability.

[0003] In traditional container construction, special steel castings are usually installed at the corners of the container, and the connection of the box is achieved by docking two steel castings. Although this method is simple, there are some problems in the actual construction process. First, the construction operation space inside the steel casting is limited, which makes the construction difficult and affects the connection strength of the node. Secondly, due to the design and installation method of the steel casting, the form of the connection node is relatively simple, lacking flexibility and safety. Therefore, there is an urgent need to provide a safe and stable container connection node. Utility Model Content

[0004] The utility model aims to solve the deficiencies in the prior art and provide a connection node for a low-rise container body.

[0005] The specific technical solutions adopted by this utility model are as follows:

[0006] The utility model provides a connection node for a low-rise container body, wherein the connection node is arranged at a corner of the container body and is used to connect with an adjacent container body; the connection node comprises a cross connector, an anti-slip pad and a gasket, wherein the cross connector comprises a first connecting plate, a second connecting plate and a cross stiffening rib vertically fixed between the first connecting plate and the second connecting plate; a plurality of connection holes for setting the connector are provided on the first connecting plate;

[0007] Each container body includes a steel column and a steel beam; the top and bottom ends of the steel column are respectively fixedly connected to the second connecting plate of the cross connector; the steel beams are respectively fixed on both sides of the cross stiffening ribs, and adjacent steel beams form a right angle;

[0008] The anti-slip pad and gasket are arranged on the first connecting plate of the cross connecting piece of the lower container body; after the first connecting plate of the upper container body is aligned with the first connecting plate of the lower container body, the connecting piece passes through the connecting holes of the two first connecting plates to fix the upper and lower container bodies.

[0009] Preferably, the first connecting plate, the second connecting plate and the cross stiffening ribs are all made of steel plates and are welded into a whole.

[0010] Preferably, the anti-slip pad is a rubber pad.

[0011] Preferably, the gasket is made of steel plate.

[0012] Preferably, the connecting pieces are high-strength bolts.

[0013] Preferably, the second connecting plate of the cross connector is fixed to the top and bottom ends of the steel column by welding.

[0014] Preferably, the steel beams are fixed on both sides of each cross stiffening rib by welding, so that adjacent steel beams form a right angle.

[0015] Preferably, four connection holes are provided on the first connection plate of each cross connector, which are respectively located in the four areas divided by the cross stiffening ribs.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] (1) Compared with the common connection nodes (container-specific connection corner pieces) on the market, the connection nodes provided by the utility model are mainly connected by bolts in the prior art, while the utility model provides a cross connection piece to provide operating space for the tightening of high-strength bolts. In addition, the use of high-strength bolts improves the connection strength of the node, and improves the safety and stability of the overall structure.

[0018] (2) The utility model adds rubber pads and steel plates when connecting the upper and lower container bodies.

[0024] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model. Therefore, the utility model is not limited by the specific embodiments disclosed below. The technical features in each embodiment of the utility model can be combined accordingly without conflicting with each other.

[0025] like Figure 1 As shown, the utility model provides a connection node for a low-rise container body, which is arranged at a corner of the container body and is used to connect with an adjacent container body. The connection node includes a cross connector 3, an anti-slip pad 4 and a gasket 5.

[0026] The specific structure of the cross connector 3 is as follows Figure 2 As shown, it includes a first connecting plate 301, a second connecting plate 302, and a cross stiffening rib 303 vertically fixed between the first connecting plate 301 and the second connecting plate 302. The first connecting plate 301 is also provided with a plurality of connecting holes for arranging the connecting member 6.

[0027] In the connection node provided by the utility model, the first connection plate 301 and the second connection plate 302 can both be made of steel plates. In addition, the cross stiffening ribs 303 can also be made of steel plates welded into a structure with a "cross" cross section. The first connection plate 301, the second connection plate 302 and the cross stiffening ribs 303 can be welded into a whole in the factory.

[0028] It should be noted that four connection holes may be provided on the first connection plate 301 of each cross connector 3 , which are respectively located in the four areas divided by the cross stiffening ribs 303 .

[0029] like Figure 3 As shown, each container body includes a steel column 1 and a steel beam 2. The top and bottom ends of each steel column 1 are fixedly connected to the second connecting plate 302 of the cross connector 3 by welding. The two sides of the cross stiffening rib 303 of the cross connector 3 are fixedly connected to the steel beam 2 of the container body by welding, so that adjacent steel beams 2 form a right angle.

[0030] In the connection node provided by the utility model, the anti-slip pad 4 and the gasket 5 are arranged on the first connection plate 301 of the cross connection member 3 of the lower container body, such as Figure 3 After the first connecting plate 301 of the upper container body is aligned with the first connecting plate 301 of the lower container body, the connecting member 6 passes through the connecting holes on the two first connecting plates 301 to fix the upper and lower container bodies together.

[0031] It should be noted that the connection member 6 in the present invention preferably adopts a high-strength bolt.

[0036] Then align the first connecting plate 301 of the upper container body with the first connecting plate 301 of the lower container body, and use high-strength bolts to pass through the bolt holes on the two first connecting plates 301. Tighten each high-strength bolt to fix the upper and lower container bodies.

[0037] Example 2

[0038] This embodiment provides a method of connecting four upper and lower container bodies by using the above connection nodes, wherein two container bodies are arranged on the lower layer and two container bodies are arranged on the upper layer, such as Figure 4 shown.
