Description

Technical Field

[0001] The utility model relates to the field of installation of factory building supports and hangers, in particular to a connection node between a main auxiliary beam and a secondary auxiliary beam. Background Art

[0002] For example, in the Chinese invention patent application publication number CN115495822A - A deepening design method for a ceiling conversion layer under limited conditions in a super - large three - dimensional space, auxiliary beams are arranged between trusses to strengthen the support structure. Generally, the auxiliary beams often adopt a grid - like form, and the main and secondary auxiliary beams are cross - welded to form a grid. However, in this connection form of the main and secondary auxiliary beams, due to too many cross - nodes, there are too many welding processes, the assembly is complex, the amount of hot - work is large, and the installation efficiency is low; moreover, the welding method requires breaking the paint surface of the original auxiliary beam, and then repainting it twice after welding, resulting in poor appearance. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a connection node between a main auxiliary beam and a secondary auxiliary beam, which can effectively reduce the welding process, has a high degree of prefabrication, faster construction efficiency, a more beautiful finished product after construction, a safer construction process, and reduces the later paint repair rate.

[0004] To solve the above problems, a connection node between a main auxiliary beam and a secondary auxiliary beam is adopted, which includes:

[0005] H - shaped steel main auxiliary beam;

[0006] The main auxiliary beam connecting plate, one end of which extends into the inner side of the H - shaped steel main auxiliary beam and is welded closely to the upper flange, web and lower flange of the H - shaped steel main auxiliary beam, the other end of which extends out of the H - shaped steel main auxiliary beam, and a plurality of first bolt holes are arranged at the extending end;

[0007] H - shaped steel secondary auxiliary beam, which is vertically fixed on the H - shaped steel main auxiliary beam, is arranged between two adjacent parallel H - shaped steel main auxiliary beams, and both ends thereof are extended into by the extending end of the main auxiliary beam connecting plate. The extending end of the main auxiliary beam connecting plate is closely attached to the upper flange, web and lower flange of the end of the H - shaped steel secondary auxiliary beam. A plurality of second bolt holes are opened on the web of the end of the H - shaped steel secondary auxiliary beam and correspond to the first bolt holes;

[0008] Bolt - nut assembly, which passes through the first bolt holes and the second bolt holes and is tightened.

[0009] With such a structure, the H - shaped steel main auxiliary beam and the H - shaped steel secondary auxiliary beam can be spliced through the bolt - nut assembly to reduce the welding process.

[0010] As a further improvement of the utility model, at least one side of the H - shaped steel main auxiliary beam is connected with an L - shaped main auxiliary beam connecting plate.

[0011] With such a structure, it is convenient for fitting and installation when the section size of the secondary H-shaped steel auxiliary beam is smaller than that of the primary H-shaped steel auxiliary beam.

[0012] As a further improvement of the present utility model, one side of the primary H-shaped steel auxiliary beam is connected with a straight plate-shaped primary auxiliary beam connecting plate, and the other side is connected with an L-shaped primary auxiliary beam connecting plate.

[0013] With such a structure, it is suitable for secondary H-shaped steel auxiliary beams of different specifications.

[0014] As a further improvement of the present utility model, the upper and lower sides of the extended end of the primary auxiliary beam connecting plate are retracted and rounded, and the starting position of the retraction is the intersection position of the upper and lower sides of the primary auxiliary beam connecting plate and the edges of the upper and lower flanges of the primary H-shaped steel auxiliary beam.

[0015] With such a structure, stress concentration occurs at the wall intersection position, which easily causes the cross-section to crack.

[0016] As a further improvement of the present utility model, at the end where the primary auxiliary beam connecting plate extends into the inner side of the primary H-shaped steel auxiliary beam, triangular notches are provided at the upper and lower corners.

[0017] With such a structure, it is beneficial to adapt to thermal expansion and contraction and prevent the cross-section from cracking during deformation.

[0018] As a further improvement of the present utility model, the first bolt hole position is an oblong hole.

[0019] With such a structure, during thermal expansion and contraction, the oblong hole will not restrict the movement of the secondary H-shaped steel auxiliary beam.

[0020] As a further improvement of the present utility model, the second bolt hole position is a round hole.

[0021] As a further improvement of the present utility model, when the bolt-nut assembly is located on one side of the oblong hole, a channel-shaped gasket is used, and the channel-shaped gasket spans the oblong hole. When the bolt-nut assembly is located on one side of the round hole, an annular gasket is used.

[0022] With such a structure, the channel-shaped gasket reduces the stress area, which is beneficial to the thermal expansion and contraction of the secondary H-shaped steel auxiliary beam.

[0023] As a further improvement of the present utility model, when the secondary H-shaped steel auxiliary beam is spliced with the straight plate-shaped primary auxiliary beam connecting plate, double-row holes are used for splicing up and down, and the second bolt hole position in the lower row uses a vertical oblong hole.

[0024] The present utility model replaces a large amount of welding work with bolt connection, reduces on-site welding operations and aerial work operations, has a high degree of prefabrication, faster construction efficiency, more beautiful construction products, safer construction process, and is beneficial to reducing the later paint repair rate.

[0038] The H-shaped steel secondary secondary beam 3 is vertically fixed to the H-shaped steel main secondary beam 1, is arranged between two adjacent parallel H-shaped steel main secondary beams 1, and both ends thereof are extended into by the extending end of the main secondary beam connecting plate 2. The extending end of the main secondary beam connecting plate 2 is welded closely to the upper flange, web and lower flange of the end of the H-shaped steel secondary secondary beam 3. A plurality of second bolt hole positions 301 are opened on the web of the end of the H-shaped steel secondary secondary beam 3 and correspond to the first bolt hole positions 201;

[0040] With such a structure, the H-shaped steel main secondary beam 1 and the H-shaped steel secondary secondary beam 3 can be spliced through the bolt-nut assembly 4 to reduce the welding process.

[0041] In this embodiment, at least one side of the H-shaped steel main secondary beam 1 is connected with the L-shaped main secondary beam connecting plate 2.

[0042] With such a structure, when the specification of the secondary H-shaped steel auxiliary beam 3 is smaller than that of the primary H-shaped steel auxiliary beam 1, it is convenient for fitting and installation.

[0043] In this embodiment, one side of the primary H-shaped steel auxiliary beam 1 is connected to a straight plate-shaped primary and secondary beam connection plate 2, and the other side is connected to an L-shaped primary and secondary beam connection plate 2.
