Description

Technical Field

[0001] The utility model relates to the technical field of construction of coastal passenger ports, in particular to a unit module splicing adjustment structure of a bottom-hanging fishing net aluminum structure ceiling structure. Background Art

[0002] With the development of society and the demand for shipping, more and more attention is paid to the construction of passenger ports. In the field of coastal passenger port construction, the most common roof truss system of passenger ports is the steel structure system, which has a single system structure. In the Zhuhai Jiuzhou Passenger Port project, a new type of down-hanging fishing net aluminum ceiling combined steel and aluminum roof truss structural system was found. The system has many structural layers, many construction difficulties, and great difficulty in structural splicing. The construction technology of this structural system is not mature enough.

[0003] Traditional steel-aluminum structure connections usually weld the node plate directly to the steel truss, and the lower chord aluminum rod is then connected to the node plate through the connecting plate. The effects of this connection method are: because the node plate is welded to the steel truss in advance and the angle is determined, the angle deviation between the node plate and the connecting plate is large during connection; the design requires a distance of 36cm from the steel box girder to the centerline of the connecting plate, and the welding length of the node plate has been determined in advance. During connection, the distance does not meet the requirements due to errors in the connecting plate. Utility Model Content

[0004] The utility model aims to provide a unit module splicing adjustment structure of a hanging fishing net aluminum ceiling structure to solve the technical problems of large deviation in the docking angle between the node plate and the connecting plate and the failure of the steel-aluminum structure distance to meet the requirements in the traditional mode.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A unit module splicing and adjustment structure of a bottom-hanging fishing net aluminum ceiling structure comprises a box-type frame beam, on the vertical side wall of which an upper chord circular steel tube inclined upward is fixedly welded, the box-type frame beam and the upper chord circular steel tube are both fixedly connected with a node plate, the node plate is fixedly connected with a lower chord aluminum rod via a connecting plate, and the connecting plate is fixedly connected to the node plate and the lower chord aluminum rod via a plurality of rivets.

[0007] As a further solution of the utility model: reinforcing rib plates are fixedly connected to the four corners of the inner hole of the box-type frame beam.

[0008] As a further solution of the utility model: the connection plates are provided in two groups, which are respectively located on both sides of the node plate.

[0009] As a further solution of the utility model: at least two rows of rivets are provided for connecting the connection plate, the node plate and the lower chord aluminum rod, and at least three rivets are provided in each row.

[0010] As a further solution of the utility model: a connecting pad is provided between the node plate and the lower chord aluminum rod.

[0011] As a further solution of the utility model: the node plate is provided with a beam end face connected to the box frame beam and a circular tube end face matching the outer surface of the upper chord circular steel tube, the beam end face is connected to the circular tube end face, and the angle between the beam end face and the circular tube end face is equal to the angle between the box frame beam and the upper chord circular steel tube.

[0012] Beneficial effects of the utility model:

[0013] (1) The utility model connects the lower chord aluminum parts, the connecting plate and the node plate into a whole, and then welds them to the upper chord steel truss structure. This new connection method controls the distance between the steel and aluminum structures by 36 cm by pre-connecting the node plate and the connecting plate and adjusting the length of the node plate. The angle is adjusted by manual welding on site to meet the angle requirements.

[0014] (2) By setting two sets of connecting plates to clamp the two ends of the node plate and the lower chord aluminum rod, the stability of the connection between the node plate and the lower chord aluminum rod is effectively improved, thereby improving the overall connection strength of the entire structure.

[0015] (3) A connecting pad is provided between the node plate and the lower chord aluminum member. On the one hand, it protects the node plate and the lower chord aluminum member and prevents the connection between the node plate and the lower chord aluminum member from being damaged by direct pressure. On the other hand, the connecting pad increases the friction coefficient of the connection between the node plate and the lower chord aluminum member, thereby improving the stability of the connection between the node plate and the lower chord aluminum member.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 3 As shown, the utility model is a unit module splicing and adjustment structure of a bottom-hanging fishing net aluminum ceiling structure, including a box-type frame beam 1, on the vertical side wall of which an upper chord round steel tube 2 inclined upward is fixedly welded, and a node plate 3 is fixedly connected to the box-type frame beam 1 and the upper chord round steel tube 2, and a lower chord aluminum rod 5 is fixedly connected to the node plate 3 via a connecting plate 4, and the connecting plate 4 is fixedly connected to the node plate 3 and the lower chord aluminum rod 5 via a plurality of rivets 6.

[0023] The four corners of the inner hole of the box-type frame beam 1 are fixedly connected with reinforcing ribs 11. Since the box-type frame beam 1 serves as an integral connection support, it is necessary to ensure that the box-type frame beam 1 maintains sufficient strength. By arranging reinforcing ribs 11 at the four corners inside, the overall strength is improved to ensure the stability of the entire structural connection.

[0024] The connecting plates 4 are provided with two groups, which are respectively located on both sides of the node plate 3. The connecting plates 4 are used to connect the node plate 3 and the lower chord aluminum rod 5. By providing two groups of connecting plates 4, the two ends of the node plate 3 and the lower chord aluminum rod 5 are clamped, thereby effectively improving the stability of the connection between the node plate 3 and the lower chord aluminum rod 5, and improving the overall connection strength of the entire structure.

[0025] At least two rows of rivets 6 are provided for connecting the connection plate 4 with the node plate 3 and the lower chord aluminum rod 5, and at least three rivets are provided in each row.

[0026] The node plate 3 and the lower chord aluminum rod 5 are quickly connected by the rivets 6, and the connection method of the rivets 6 is convenient and quick to assemble and disassemble, and the connection strength is improved by arranging multiple rows of multiple rivets 6.

[0027] Specifically, the rivet 6 is a stainless steel ring groove rivet specially used for aluminum structure.

[0030] The node plate 3 is provided with a beam end face 31 connected to the box frame beam 1 and a circular tube end face 32 matched with the outer surface of the upper chord circular steel tube 2. The beam end face 31 is connected to the circular tube end face 32, and the angle between the beam end face 31 and the circular tube end face 32 is equal to the angle between the box frame beam 1 and the upper chord circular steel tube 2.

[0031] Specifically, by providing a beam end face 31 and a round tube end face 32 that match the box frame beam 1 and the upper chord round steel tube 2, the stability of the connection between the node plate 3 and the box frame beam 1 and the upper chord round steel tube 2 can be effectively improved.
