In general heat exchanger heat exchanger tube is supported using entire plate forms such as deflection plate, supporting plates, but nuclear power makes
Its structures shape of the heat exchanger of C-shaped pipes beam can not use board-like support, and generally use support strips are to heat transfer
Pipe is supported, and support bar is welded in support component.Because the width of support bar is smaller, the weld seam being connected with component can not be held
By larger stress.Under thermal force, seismic (seismal, when support bar stress is larger, weld seam position may be damaged, shadow
Ring structural intergrity.In addition, if the weldering of increase support bar and support component weld seam is high, support bar deformation can be caused larger, from
And influence the installation and fixation of heat-transfer pipe.
The content of the invention
In view of the deficiencies in the prior art, the technical problems to be solved by the invention are that solve C-shaped tube bundle heat exchanger branch
Stay support bar weld seam stress under thermal force, seismic (seismal is excessive and the problems such as welding deformation.
To achieve the above object, the present invention proposes a kind of fixed structure of C-shaped pipes beam heat exchanger supports bar.Using connection
In in fixed plate, connecting plate is connected plate weld by bolt (stud), and support bar is fixed, avoids support bar and support component
Directly weld, while be advantageous to Equip- ment manufacture and installation.Specifically, technical scheme provided by the invention is as follows：
A kind of fixed structure of C-shaped pipes beam heat exchanger supports bar, including support member, connection component and support bar；It is described
The side of connection component is fixed on the support member, and the opposite side of the connection component is provided with connecting plate, the support bar
End is located in the connection component, and is fixedly connected by fastener with the connecting plate.
Preferably, the connection component includes welded plate, lockplate and fixed plate successively；The fixed plate and the connection
Plate is fixedly connected；The lockplate is provided with the groove that can accommodate the support bar end, and the support bar is supported for fixed；
The welded plate is fixed by welding on the support member, and the welded plate is provided with screwed hole；The connection component also wraps
Multiple bolts are included, the multiple bolt passes through the screwed hole in the fixed plate and the lockplate, with the welded plate
It is connected through a screw thread, the fixed plate, the lockplate and the welded plate is fixed.
Preferably, the fixed plate is formed in one with the connecting plate.
Preferably, the fixed plate with the connecting plate by being welded and fixed.
Preferably, the fastener is bolt (stud) and nut.
Preferably, the connection component is made up of steel plate.
Preferably, the support bar is provided with multiple through holes, the heat-transfer pipe for supporting C-shaped tube bundle heat exchanger.
Compared with prior art, advantage of the invention is：
1) it is welded in using connection component on support member, so as to add weld size；Strengthened using the mode of being integrally formed
Intensity between connection component and connecting plate；
2) support bar is connected replacement welding with connecting plate using bolt (stud), avoids welding deformation, is also beneficial to support
The manufacture installation of bar.
The method of the present invention and caused technique effect are described further below with reference to accompanying drawing, to be fully understood from
The purpose of the present invention, feature and effect.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
It is as shown in Figure 1 the fixed structure chart of C-shaped pipes beam heat exchanger supports bar of the invention.Fixed structure includes support
Part 9, connection component and support bar 4；The side of connection component is fixed on support member 9, and the opposite side of connection component is provided with connection
Plate 3, the end of support bar 4 are located in connection component, and are fixedly connected by fastener with connecting plate 3.
Wherein, connection component preferably includes welded plate 8, lockplate 7 and fixed plate 6 successively；Fixed plate 6 and connecting plate 3
It is fixedly connected；Lockplate 7 is provided with the groove (not shown) that can accommodate support bar end, and support bar 4 is supported for fixed；
Welded plate 8 is fixed by welding on support member 9, and welded plate 8 is provided with screwed hole；Connection component also includes multiple bolts 5, more
Individual bolt 5 is connected through a screw thread through the screwed hole in fixed plate 6 and lockplate 7, with welded plate 8, by fixed plate 6, lockplate 7
Fixed with welded plate 8.
In the present embodiment, fixed plate is preferably formed in one with connecting plate, can also be by being welded and fixed；Connection support
