Description

Technical Field

[0001] The utility model belongs to the field of assembled steel structure buildings, and in particular relates to a full-bolt beam connection node of a beam-wing combination and an assembled steel structure. Background Art

[0002] The statements in this section merely provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] In prefabricated steel structure buildings, the rationality of the design of the connection nodes of column and beam components directly affects the processing, installation and reliability of the components. Therefore, the design of the connection nodes between beams and columns, beams and beams, columns and columns, supports and beams and columns is extremely critical. Among them, the connection between the column and the main beam is connected by bolts using a short cantilever beam welded on the steel column. In general, the cross-sectional dimensions of the main beam and the connecting cantilever beam are the same. When the full bolt connection is used, the connection plate located above the upper flange of the I-beam at the node and the bolts connecting the upper flange and the connection plate make the upper surface of the node bolts higher than the upper surface of the steel beam. Figure 1 and Figure 2 As shown, the height difference causes the corrugated steel sheet used as the floor slab to generate initial deformation when it is laid on the beam, making the stress on the floor slab more complicated, which has an adverse effect on its bearing capacity and slows down the construction speed.

[0036] according to Figure 3 and Figure 4 The embodiment of the utility model provides a full-bolt beam connection node of a beam-wing combination, which includes: an I-beam, a first connecting plate 2, a second connecting plate 7, a corrugated steel plate 4 and a wing plate 8; at the upper flange connection seam of two sections of I-beams, a wing plate 8 is welded on both sides of the upper flange 3 of each section of the I-beam; the first connecting plate 2 is fixed to the upper flange connection seam and the lower flange connection seam of the two sections of the I-beam by bolts 1 respectively; a corrugated steel plate 4 (which serves as a floor decking) is also laid between the first connecting plate 2 and the upper flange connection seam; the second connecting plate 7 is fixed to both sides of the web 8 connection seam of the two sections of the I-beams by bolts 1.

[0037] In order to ensure the bearing capacity at the variable cross-section, the outer end surface of each flange 8 is welded to a stiffening rib 9, and the stiffening rib 9 is also welded to the web 5, the upper flange 3 and the lower flange 6 of the I-beam.

[0038] In one or more embodiments, all stiffening ribs 9 are identical, which can ensure the balance of the bearing capacity of the wing plate.

[0039] In some specific embodiments, the flanges 8 welded on both sides of the upper flanges of the two sections of I-beams are symmetrically arranged along the upper flange connection seams, which can also ensure the balance of the bearing capacity of the flanges.

[0040] In other embodiments, the wing plates 8 welded on both sides of the upper flange of each section of the I-beam are identical, so that the wing plates can be processed uniformly, thereby improving the overall assembly efficiency.

[0041] In a specific implementation process, the sum of the width of the wing plate 8 and the width of the upper flange 3 of the I-beam is greater than or equal to the width of the corrugated steel plate 4. The width of the first connecting plate 2 is equal to the width of the upper flange 3 and the lower flange 6 of the I-beam. The height of the second connecting plate 7 is equal to the width of the web 5 of the I-beam.

[0042] In the fully bolted beam connection node of the beam-wing combination of the present embodiment, a wing plate is welded on both sides of the upper flange of each I-beam section at the upper flange connection seam of the two sections of I-beams, thereby increasing the cross-sectional size of the beam within the connection node range. This effectively solves the problem that when installing the corrugated steel plate, due to the presence of the upper flange connection plate and bolts higher than the top surface of the beam at the fully bolted beam connection node, the corrugated steel plate needs to be partially lifted, which slows down the construction speed, reduces the construction quality, and weakens the bearing capacity of the corrugated steel plate at this location. This allows the corrugated steel plate to be laid flatly, and avoids the phenomenon of leakage of slurry and liquid when casting the roof panel.

[0043] In one or more embodiments, a prefabricated steel structure is further provided, which includes a fully bolted beam connection node of the beam-wing combination as described above.
