Described nuclear power station ring hangs load test bracket, its further feature is that this bracket also comprises two row's guardrails, two row's guardrails are placed respectively at the two ends of secondary beam, guardrail comprises two fence posts, floor stringer and brace, floor stringer is placed on the end of secondary beam, two fence posts are placed respectively at the both ends of floor stringer, and two braces intersect and are connected respectively with the upper and lower end portion of two fence posts.
Described nuclear power station ring hangs load test bracket, and its further feature is that described girder, secondary beam, column are H shaped steel.
Described nuclear power station ring hangs load test bracket, its further feature is that described many secondary beams are 6 secondary beams, is equidistantly distributed on two girders, and described multiple balancing weights are divided into 6 heaps, on 6 secondary beams, become array distribution, this bracket can bear the rated load of at least 340 tons.
Described nuclear power station ring hangs load test bracket, and its further feature is between girder and secondary beam, to be also bolted connection.
Door type frame, secondary beam, guardrail all can be dismantled, and therefore the different parts that are disassembled into of this bracket are transported in factory building respectively, then in factory building, carry out assembled.
Brief description of the drawings
The above and other feature of the present utility model, character and advantage are by by becoming more obvious below in conjunction with the description of drawings and Examples, wherein:
Fig. 1 is the front view that the nuclear power station ring of an embodiment of the utility model hangs load test bracket.
Fig. 2 is the side view that the nuclear power station ring of an embodiment of the utility model hangs load test bracket.
Fig. 3 is the vertical view that the nuclear power station ring of an embodiment of the utility model hangs load test bracket.
Embodiment
Below in conjunction with specific embodiments and the drawings, the utility model is described in further detail; set forth in the following description more details so that fully understand the utility model; but the utility model obviously can be implemented with the multiple alternate manner that is different from this description; those skilled in the art can do similar popularization, deduction according to practical situations without prejudice to the utility model intension in the situation that, therefore should be with the content constraints of this specific embodiment protection domain of the present utility model.
Can recognize that from Fig. 1 to Fig. 3 nuclear power station ring the utility model embodiment hangs the detailed structure of load test bracket; but it should be noted that; these and follow-up other accompanying drawing are all only as example; it is not to draw according to the condition of equal proportion, and should be using this as the protection domain of the utility model actual requirement is construed as limiting.
As shown in Figure 1 to Figure 3, nuclear power station ring hangs load test bracket and comprises two door type frames and six roots of sensation secondary beam 1, two parallel setting settings of type frame, each type frame comprise welding on girder 2, girder 2 two parallel columns 5, be welded on the horizontally disposed crossbeam 6 between the top of two columns 5, the top of each column 5 is welded with hanger 10, six roots of sensation secondary beam 1 is placed on two girders 2 and is crisscross with girder 2, and multiple balancing weight (not shown)s are placed on secondary beam 1.
For the ease of place balancing weight, divide placement balancing weight region division 4 limited blocks 3.
For the balancing weight that prevents placement in heaps is toppled over, nuclear power station ring hangs load test bracket and also comprises two row's guardrails, two row's guardrails are placed respectively at the two ends of six roots of sensation secondary beam 1, guardrail comprises two fence posts 8, floor stringer 9 and brace 7, floor stringer 9 is placed on the end of secondary beam 1, two fence posts 8 are placed respectively at the both ends of floor stringer 9, and two braces 7 intersect and are connected respectively with the upper and lower end portion of two fence posts 8.
Described girder 2, secondary beam 1, column 5 are H shaped steel.
Before bracket is lifted by crane, be to be placed on additional beam, additional beam can adopt Box section beam.
The door type frame being welded as a whole member lifts load in order to support secondary beam and to transmit.In the time of designing and calculating, be appreciated that and need to check secondary beam, girder, the rigidity of each beam belongs to serviceability limit state, therefore adopt normal working load while calculating, get load standard value, do not take advantage of partial safety factor for load, and can not consider that the cross section that bolt hole causes weakens, and does not take advantage of dynamic coefficient to dynamic load standard value.When secondary beam is placed on additional Liang Shangshi, the gravity extended line of counterweight is still on additional beam section, and regarding as of can being similar to do not produce degree of disturbing, and can check.In addition, consider the guarantee of the resistance to overturning of this framework, girder by secondary beam as web member, secondary beam by balancing weight as web member, so can calculate its stability.Secondary beam passes to girder by surface of contact by power, can be bolted fixingly between girder and secondary beam, but bolt only plays fixing effect, is not drawn, the effect of pressure, so can check.The link position of column and hanger and miscellaneous part all adopts full penetration butt-weld, weld seam basic with member etc. by force, butt welded seam is tested according to secondary standard, without it is checked.
Main material is Q345B, and hanger material is Q420a, and secondary beam material is Q345B, and bracket as shown in Figure 1 to Figure 3 can bear the rated load of at least 340 tons, and can normally carry into reactor building.The check of the intensity to bracket is calculated and can be carried out by you GB50017-2003 of reference steel structural design, and nuclear power station ring as shown in the figure hangs load test bracket and in inventor's practice, is verified.In the construction of nuclear power station of AP1000 type, after the cover head buckle closure of nuclear island, carry out ring and hung main hook load test, this test bracket can enter ring from main pump transport channel and hang load test region, both can meet AP1000 nuclear island 135 ' floor ground bearing capacity, can gradation introduce again, can in nuclear island, assemble, the ring with reusable function hangs load test bracket.
Although the utility model with preferred embodiment openly as above, it is not for limiting the utility model, and any those skilled in the art, not departing from spirit and scope of the present utility model, can make possible variation and amendment.Therefore, every content that does not depart from technical solutions of the utility model, any amendment, equivalent variations and the modification above embodiment done according to technical spirit of the present utility model, within all falling into the protection domain that the utility model claim defines.
