Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an articulated structure of a main beam and a secondary beam. Background Art

[0002] In the construction of box-section beams, the most important process is the connection between the main beam and the secondary beam. Although the hinged connection between the main and secondary beams is a common connection method, for box-section beams of steel structures as secondary beams, due to the wide variety of box-section beams, there are no specific regulations and practices for hinged connection nodes in my country's current specifications and drawings.

[0003] With the accumulation of long-term engineering practice experience, some commonly used practices have been derived from the practice of hinged structures. Practice 1: Usually only the web of the secondary beam and the main beam are connected through the connecting plate, while the flange of the secondary beam and the main beam are not connected. Due to the influence of the two webs, the construction of the area in the middle of the web is inconvenient, and the existence of the two webs cannot fully form a hinged effect.

[0004] Method 2 is an improvement on Method 1. Method 2: Use H-shaped steel beams to connect the secondary beam and the main beam. The steel web of the H-shaped steel beam extends into the secondary beam and is welded to the stiffening plate set in the secondary beam. This node method reduces the difficulty of installation and structural corrosion protection to a certain extent, but it still has certain requirements for on-site construction. The stiffening plate inside the secondary beam and the steel web of the H-shaped steel beam extending into the secondary beam need to be processed in the factory, and it is inconvenient to operate inside the box-type steel beam. Utility Model Content

[0005] The purposes of the utility model are: 1. To make the articulated structure method more convenient during construction, thereby ensuring the quality of construction; 2. To make the materials used in the articulated structure method more economical than the H-shaped steel beam without steel flange in the second method.

[0006] In order to achieve the above-mentioned purpose, the utility model provides an articulated structure of a main beam and a secondary beam, which includes: a main beam, a secondary beam, a first connecting plate, a second connecting plate, an embedded steel plate and a head plate; the main beam extends along a first direction, the first connecting plate, the second connecting plate and the secondary beam extend along a second direction, the secondary beam is a steel box beam, the embedded steel plate is buried in the main beam and extends along the first direction, the head plate is welded to a side of the secondary beam close to the main beam along the second direction, the first connecting plate and the second connecting plate are arranged between the main beam and the secondary beam and are fixedly connected to each other, one end of the first connecting plate is welded to the embedded steel plate, and one end of the second connecting plate is welded to the head plate.

[0007] Furthermore, the hinged structure of the main beam and the secondary beam also includes bolts, the first connecting plate and the second connecting plate overlap to form a connecting area, and the bolts are arranged in the connecting area to penetrate and fix the first connecting plate and the second connecting plate in sequence.

[0008] Furthermore, there are multiple bolts, and the multiple bolts are arranged in a matrix to connect the first connection plate and the second connection plate.

[0009] Furthermore, the main beam is a concrete member.

[0010] Furthermore, the hinged structure of the main beam and the secondary beam also includes anchor bars arranged along the second direction, and the embedded steel plate is anchored in the main beam through the anchor bars.

[0011] Furthermore, the hinged structure of the main beam and the secondary beam also includes a plurality of anchor bars, and the plurality of anchor bars are arranged at intervals.

[0012] Furthermore, the embedded steel plate is connected to the first connecting plate by double-sided fillet welding.

[0013] Furthermore, the head plate and the secondary beam are connected by groove welding.

[0014] Furthermore, the thickness of the head plate is 14 mm, and the thickness of the first connecting plate and the second connecting plate is 20 mm.

[0015] Compared with the prior art, the hinged structure of the main beam and the secondary beam of the embodiment of the utility model has the following beneficial effects: 1) From the perspective of structural stress, at the hinged structure of the main and secondary beams, the flange stress of the H-shaped steel beam in the second method is relatively small. Therefore, when the actual span of the component is small or the stress is small and a small-section box-shaped steel beam is used as the secondary beam, the H-shaped steel beam can be replaced by a connecting plate, and the flange is eliminated, saving materials and reducing costs; 2) Compared with the steel web of the H-shaped steel beam that needs to be constructed deep inside the secondary beam, the first connecting plate and the second connecting plate are fixed to each other on the outside of the secondary beam, which is more convenient for construction, thereby ensuring the quality of construction.

[0024] In the description of the utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood according to specific circumstances.

[0025] like Figure 1 to Figure 5 As shown, an articulated structure of a main beam 1 and a secondary beam 2 in a preferred embodiment of the utility model comprises: a main beam 1, a secondary beam 2, a first connecting plate 3, a second connecting plate 4, an embedded steel plate 5 and a head plate 6; the main beam 1 extends along a first direction, the first connecting plate 3, the second connecting plate 4 and the secondary beam 2 extend along a second direction, the secondary beam 2 is a steel box beam, the embedded steel plate 5 is buried in the main beam 1 and extends along the first direction, the head plate 6 is welded to a side of the secondary beam 2 close to the main beam 1 along the second direction, the first connecting plate 3 and the second connecting plate 4 are arranged between the main beam 1 and the secondary beam 2 and are fixedly connected to each other, one end of the first connecting plate 3 is welded to the embedded steel plate 5, and one end of the second connecting plate 4 is welded to the head plate 6.

[0026] Based on the above scheme, the construction process of the utility model is as follows: after the embedded steel plate 5 is embedded in the main beam 1, the first connecting plate 3 is welded to the embedded steel plate 5, the head plate 6 is welded to one side of the secondary beam 2, and then the second connecting plate 4 is welded to the head plate 6, and then the first connecting plate 3 and the second connecting plate 4 are fixedly connected to each other. On the one hand, from the perspective of structural stress, at the hinged structure of the main and secondary beams 2, the flange stress of the H-shaped steel beam in the second method is relatively small; therefore, when the actual span of the component is small or the stress is small and a small-section box-shaped steel beam is used as the secondary beam 2, the H-shaped steel beam can be replaced by a connecting plate, and the flange is eliminated, saving materials and reducing costs. On the other hand, compared with the steel web of the H-shaped steel beam that needs to be constructed deep into the interior of the secondary beam 2, this embodiment is more convenient to construct by fixing the first connecting plate 3 and the second connecting plate 4 to each other on the outside of the secondary beam 2, thereby ensuring the quality of construction.

[0027] Preferably, the hinged structure of the main beam 1 and the secondary beam 2 further includes bolts 7, the first connecting plate 3 and the second connecting plate 4 overlap to form a connecting area, and the bolts 7 are arranged in the connecting area to sequentially penetrate and fix the first connecting plate 3 and the second connecting plate 4. The bolts 7 connecting the first connecting plate 3 and the second connecting plate 4 are not only convenient for construction, but also the connection strength between the first connecting plate 3 and the second connecting plate 4 meets the requirements of mechanical verification.

[0028] Preferably, there are multiple bolts 7, and the multiple bolts 7 are arranged in a matrix to connect the first connecting plate 3 and the second connecting plate 4. This arrangement helps to evenly distribute the load and enhance the stability and reliability of the connection.

[0029] Preferably, the main beam 1 is a concrete member. The main beam 1 and the embedded steel plate 5 are fixed to each other by concrete, which further improves the connection strength and structural integrity between the main beam 1 and the embedded steel plate 5.

[0030] Preferably, the hinged structure of the main beam 1 and the secondary beam 2 further includes anchor bars 8 arranged along the second direction, and the embedded steel plate 5 is anchored in the main beam 1 through the anchor bars 8. On the one hand, the connection strength is enhanced: the use of the anchor bars 8 can significantly improve the connection strength between the main beam 1 and the embedded steel plate 5, ensuring the stability and bearing capacity of the structure. On the other hand, the integrity of the structure is improved: the embedded steel plate 5 is anchored by the anchor bars 8, which can strengthen the connection between the main beam 1 and the embedded steel plate 5, making the entire structure more integrated and improving the overall rigidity.

[0031] Preferably, the hinged structure of the main beam 1 and the secondary beam 2 further includes a plurality of anchor bars 8, and the plurality of anchor bars 8 are arranged at intervals, so as to further improve the connection strength between the main beam 1 and the embedded steel plate 5 and the structural integrity.

[0032] Specifically, the number of anchor bars 8 in this embodiment is 16, and the 16 anchor bars 8 are arranged in a matrix and fixed to the embedded steel plate 5 to improve the reliability of the connection between the embedded steel plate 5 and the main beam 1.

[0033] Preferably, the embedded steel plate 5 is connected to the first connecting plate 3 by double-sided fillet welding. On the one hand, the connection strength is enhanced: the double-sided fillet welding can provide a higher connection strength, making the connection between the embedded steel plate 5 and the first connecting plate 3 more secure. On the other hand, the structural stability is improved: the fillet welding connection can effectively transfer the force from the first connecting plate 3 to the embedded steel plate 5, improving the stability of the entire structure.

[0034] Preferably, the head plate 6 is connected to the secondary beam 2 by groove welding. On the one hand, the strength connection is improved: groove welding is a high-strength connection method that can provide good mechanical properties and ensure the bearing capacity of the structure. On the other hand, the integrity is improved: groove welding can make the head plate 6 and the secondary beam 2 form a whole, improving the overall rigidity and stability of the structure.

[0035] Preferably, the thickness of the head plate 6 is 14 mm, and the thickness of the first connecting plate 3 and the second connecting plate 4 is 20 mm. Ensure that the mechanical properties of the hinged structure of the main beam 1 and the secondary beam 2 meet the verification requirements.

[0036] In summary, the embodiment of the utility model provides a hinged structure of a main beam 1 and a secondary beam 2. On the one hand, from the perspective of structural stress, at the hinged structure of the main and secondary beams 2, the flange stress of the H-shaped steel beam in the second method is relatively small; therefore, when the actual span of the component is small or the stress is small and a small-section box-shaped steel beam is used as the secondary beam 2, the H-shaped steel beam can be replaced by a connecting plate, and the flange is eliminated, saving materials and reducing costs. On the other hand, compared with the steel web of the H-shaped steel beam that needs to be constructed deep inside the secondary beam 2, this embodiment is more convenient to construct by fixing the first connecting plate 3 and the second connecting plate 4 to each other on the outside of the secondary beam 2, thereby ensuring the quality of construction.
