Abstract
A connecting node of a transverse expansion joint of a portal rigid frame is characterized in that a second steel column 9 in an original node is omitted, an H-shaped bracket 5 is arranged on a steel column 1 and serves as a vertical support of a second steel beam 2, a sufficient gap, namely an expansion joint 8, is reserved between the second steel beam 2 and the steel column 1, and a poly-tetra-n-vinyl-acetate (Polytetrafluoroethylene) plate 4 is arranged between the bracket 5 and the second steel beam 2 to overcome friction force and ensure effective sliding between the second steel beam 2 and the bracket 5; meanwhile, in order to ensure that the second steel beam 2 can only transversely displace and limit the falling of the steel beam caused by overlarge displacement, a limiting connecting plate 6 is arranged and is connected with the second steel beam 2 by double-nut loose bolts and long round holes 7; the improved node is simple in structure, convenient to design, manufacture and install, especially compared with an original node, one steel column is reduced, the steel consumption is effectively reduced, and the economic benefit is obvious.
Description
The technical field is as follows:
the utility model belongs to the field of steel structure buildings, and relates to a connecting node of a transverse expansion joint of a portal rigid frame.
Background art:
with the increasingly wide application of portal rigid frame structures in the field of industrial buildings, industrial buildings which are transversely ultra-wide are often encountered, the temperature stress becomes a non-negligible problem, a factory building is generally divided into independent temperature units, and the temperature stress problem is avoided.
The utility model has the following contents:
in order to overcome the defects, the utility model provides a connecting node of a transverse expansion joint of a portal rigid frame.
The technical scheme adopted by the utility model for solving the technical problems is as follows:
the utility model provides a connected node of horizontal expansion joint of gate-type rigid frame, includes the steel column, is equipped with first girder steel on the steel column, is equipped with the bracket on the steel column, is equipped with the second girder steel on the bracket, is equipped with the expansion joint between second girder steel and the steel column, is equipped with spacing connecting plate on the steel column, is equipped with a plurality of longitudinal arrangement's slotted hole on the spacing connecting plate, and the two nuts that spacing connecting plate and second girder steel set up through the slotted hole loosen bolted connection.
And a polytetrafluoroethylene plate is arranged between the bracket and the second steel beam.
The long round holes are transversely arranged, and the transverse axes of the long round holes are perpendicular to the steel columns.
Due to the adoption of the technical scheme, the utility model has the following advantages:
the connection node of the transverse expansion joint of the portal rigid frame provided by the utility model has the advantages of simple connection form, simple factory manufacture, convenient and fast field installation and remarkable economic and economic benefits, and solves the problem of increased steel consumption caused by the arrangement of one more steel column in the original node.
Description of the drawings:
FIG. 1 is a schematic view of a connection joint of a transverse expansion joint of a conventional portal rigid frame;
FIG. 2 is a schematic view of the overall structure of the present invention;
in the figure: 1. a steel column; 2. a second steel beam; 3. a first steel beam; 4. a polytetrafluoroethylene sheet; 5. a bracket; 6. a limiting connecting plate; 7. a long round hole; 8. an expansion joint; 9. a second steel column.
The specific implementation mode is as follows:
the present invention will be explained in more detail by the following examples, which are intended to disclose all changes and modifications within the scope of the present invention, and the present invention is not limited to the following examples;
combine figure 2 a connected node of gate-type rigid frame transverse expansion joint, including steel column 1, be equipped with first girder steel 3 on the steel column 1, be equipped with bracket 5 on the steel column 1, be equipped with second girder steel 2 on the bracket 5, be equipped with expansion joint 8 between second girder steel 2 and the steel column 1, be equipped with limiting connection plate 6 on the steel column 1, be equipped with a plurality of longitudinal arrangement's slotted hole 7 on the limiting connection plate 6, the double nut that limiting connection plate 6 and second girder steel 2 set up through slotted hole 7 relaxs bolted connection.
And a polytetrafluoroethylene plate 4 is arranged between the bracket 5 and the second steel beam 2.
The long round holes 7 are transversely arranged, and the transverse axis of the long round holes is perpendicular to the steel column 1.
In the design, a second steel column 9 in an original node is omitted, an H-shaped bracket 5 is arranged on a steel column 1 and serves as a vertical support of a second steel beam 2, a sufficient gap, namely an expansion joint 8, is reserved between the second steel beam 2 and the steel column 1, and a poly-tetra-atmosphere vinyl plate 4 is arranged between the bracket 5 and the second steel beam 2 to overcome friction force and ensure effective sliding between the second steel beam 2 and the bracket 5; meanwhile, in order to ensure that the second steel beam 2 can only transversely displace and limit the falling of the steel beam caused by overlarge displacement, a limiting connecting plate 6 is arranged and is connected with the second steel beam 2 by double-nut loose bolts and long round holes 7; the improved node is simple in structure, convenient to design, manufacture and install, especially compared with an original node, one steel column is reduced, the steel consumption is effectively reduced, and the economic benefit is obvious.
The details of the above are not described in detail since they are prior art.
