Description

Technical Field

[0001] The invention relates to the technical field of steel structure buildings, and in particular to a modular steel structure connection node and a connection method. Background Art

[0002] Modular building is an emerging form of assembled building. Steel structure buildings are widely used due to their high strength, light weight, good overall stiffness, strong deformation resistance and other advantages. At present, the connection nodes of existing steel structures (such as the connection between beams and columns) often adopt full welding connection, bolt-welding mixed connection or full bolt connection. For example, the connection between a steel column and an H-shaped steel is to place one end of the H-shaped steel against the steel column and connect it by direct full welding connection or setting the connection to bolt or weld and bolt the angle steel at the same time. However, this type of connection method is often the connection between two steel structures. If the upper module and the lower module are connected to a steel column at the same time, the two modules need to be fixed to the steel column in turn. The two modules are independent of each other, which makes the installation steps complicated and the installation efficiency low in the actual installation process. Summary of the invention

[0003] The purpose of the present invention is to provide a modular steel structure connection node and a connection method, which solves the technical problems of complicated installation steps and low installation efficiency in the prior art.

[0027] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0028] The specific embodiment of the present invention provides a modular steel structure connection node, combined with the attached Figure 1 As shown, it mainly includes a first steel section 1, a second steel section 2, a steel column 3 and a connecting piece 4.

[0029] The first steel section 1 and the second steel section 2 are both connected to the steel column 3 through a connecting piece 4. The first steel section 1 and the second steel section 2 can be H-shaped steels. The first steel section 1 and the second steel section 2 include a first wing plate 6, a second wing plate 8, and a web plate 5 arranged between the first wing plate 6 and the second wing plate 8.

[0030] When the first steel section 1 and the second steel section 2 are arranged on the steel column 3, the webs 5 of the two are in the same direction, such as the webs 5 of the two are located on the same plane. Figure 1As shown in , the first steel section 1 is located at the top and the second steel section 2 is located at the bottom, and the webs of both are in the vertical direction. At this time, the first wing plate 6 where the first steel section 1 and the second steel section 2 are close to each other has a notch 7, one side of the connecting member 4 is connected to the steel column 3, and the other side of the connecting member 4 passes through the notch 7 and is bolted to the first steel section 1 and the second steel section 2. The same connecting member 4 can realize the connection between the first steel section 1 and the second steel section 2, and the connecting member 4 is also connected to the steel column 3. In this way, the connection between the first steel section 1 and the second steel section 2 and the steel column can be realized. The second wing plate 8 where the first steel section 1 and the second steel section 2 are far away from each other is welded to the steel column 3, and the connection strength between the first steel section 1 and the second steel section 2 and the steel column 3 is strengthened by welding. In this application, a connecting member 4 is used to realize the connection between the first steel section 1 and the second steel section 2 and the steel column 3, simplifying the connection method, thereby indirectly improving the installation efficiency, and also realizing the connection between the first steel section 1 and the second steel section 2.

[0031] In actual installation, the first steel section 1 and the second steel section 2 may be part of the upper module or the lower module respectively. For example, the first steel section 1 may be the lower steel beam of the upper module, and the second steel section 2 may be the upper steel beam of the lower module.

[0032] In a specific embodiment of the present application, there can be two connecting members 4, and the two connecting members 4 are respectively arranged on both sides of the first steel section 1 and the second steel section 2, so as to further strengthen the connection strength between the first steel section 1 and the second steel section 2 and the steel column 3 by connecting from both sides.

[0033] In some embodiments, the connecting member 4 can be a connecting plate with an L-shaped cross-section, and the two ends of the connecting member 4 are respectively close to the second wing plates 8 of the first steel section 1 and the second steel section 2, that is, to ensure that the connecting member 4 can be connected to the first steel section 1 and the second steel section 2 as much as possible, one side plate of the connecting member 4 is connected to the steel column 3, and the other side plate of the connecting member 4 is connected to the web 5 of the first steel section 1 and the second steel section 2. The connecting member 4 and the steel column 3 can be bolted, and the first steel section 1 and the second steel section 2 can also be bolted to the connecting member 4.

[0034] In some embodiments, the connecting part of the connecting member 4 is located between the first wing plate 6 and the second wing plate 8 of the first steel section 1 and the second steel section 2 to ensure a better connection effect. The connecting part of the connecting member 4 is actually at the connection position between the first steel section 1, the second steel section 2 and the steel column 3.

[0035] In some embodiments, gaps 9 are left between the two ends of the connecting member 4 and the second wing plates 8 of the first steel section 1 and the second steel section 2, respectively, so that after the connection between the first steel section 1 and the second steel section 2 and the connecting member 4 is completed, the first steel section 1 and the second steel section 2 and the steel column 3 can be welded.

[0036] A specific embodiment of the present invention provides a method for connecting a modular steel structure connection node, comprising:

[0037] Prefabricated connector 4 with bolt holes;

[0038] A notch 7 is provided at one end of the first wing plate 6 of the first steel section 1 and the second steel section 2.

[0039] Bolt holes are provided on the webs 5 of the first steel section 1 and the second steel section 2;

[0040] Opening bolt holes on the steel column 3;

[0041] Bolt the connector 4 to the steel column 3;

[0042] Bolt the first steel section 1 and the second steel section 2 to the connecting member 4 in sequence;

[0043] The second wing plates 8 of the first steel section 1 and the second steel section 2 are welded to the steel column 3 .

[0044] The connector 4 in the present application is a prefabricated component and needs to be prefabricated in a factory. Different types of connectors 4 are designed according to the types of steel sections and steel columns required for the steel structure to ensure the required connection strength.

[0045] The notch 7 may be a partial wing plate removed from one end of the H-shaped steel so that the connector 4 can pass through, or a local strip notch opened on the wing plate of the H-shaped steel to ensure that the connector can pass through.

[0046] The bolt holes on the H-shaped steel are opened on the web, corresponding to the bolt holes on the connecting member 4 .

[0047] The bolt holes on the steel column 3 are symmetrically arranged to ensure that the two connecting members 4 are bolted to the H-shaped steel from both sides.

[0048] When connecting, one side wall of the connecting piece 4 can be first pressed against the steel column 3 and connected with high-strength bolts, and then the first steel section 1 and the second steel section 2 can be connected to the other side wall of the connecting piece 4 in turn through high-strength bolts, and finally the second wing plates 8 of the first steel section 1 and the second steel section 2 can be welded at the contact position with the steel column 3.

[0049] In actual installation, since the upper module and the lower module often require multiple side steel beams to jointly form a frame, it is often necessary to set the first steel section 1 and the second steel section 2 on different side walls of the same steel column 3. To this end, the first steel section 1 and the second steel section 2 are connected in sequence on at least two side walls of the steel column 3. The steel column 3 in the present application can be a single steel column. In this case, the first steel section 1 and the second steel section 2 can be connected on the two side walls of this steel column. The steel column 3 can also be a steel column bundle composed of two, three or four. A single steel column 3 can be square steel. In this case, the first steel section 1 and the second steel section 2 can be set in the direction of the steel column bundle to achieve multi-directional expansion.
