Abstract

The invention relates to an AP1000 nuclear power dome assembling jig frame which comprises inner-circle upright columns, outer-circle upright columns and concrete foundations. The inner-circle upright columns are used for supporting dome ring beams and are arranged along the integral peripheral direction of the AP1000 nuclear dome assembling jig frame, each outer-circle upright column is used for supporting an end of a corresponding dome radial beam, the outer-circle upright columns are arranged along the integral peripheral direction of the AP1000 nuclear power dome assembling jig frame, each concrete foundation is used for supporting the other end of the corresponding dome radial beam, and the concrete foundations are arranged along the integral peripheral direction of the AP1000 nuclear power dome assembling jig frame. Each of the inner-circle upright columns and the outer-circle upright columns axially comprises two sections, the upper half sections of the inner-circle upright columns and the upper half sections of the outer-circle upright columns are detached after a dome body is completely assembled, and the lower half sections of the inner-circle upright columns and the lower half sections of the outer-circle upright columns are connected with one another by supporting brackets; the supporting brackets are connected with dome modules. The AP1000 nuclear power dome assembling jig frame has the advantages that the AP1000 nuclear power dome assembling jig frame is low in material consumption and easy and convenient to operate, and is easy to detach and transport owing to the fact that structural bolts are connected with joints, and large spaces of a jig frame structure and a lower opening of a dome can be used for reversely transporting and mounting materials of the internal modules; the jig assembling duration and the dome construction period can be effectively shortened, and the dome assembling precision can be improved.

Description

The assembled moulding bed of AP1000 nuclear power dome

Technical field

The present invention relates to the assembled moulding bed of a kind of AP1000 nuclear power dome, particularly relate to a kind of technical field that belongs to nuclear power building operations, a kind of simple and easy flexible especially, the assembled jig frame special of AP1000 dome of be convenient to restructuring, dismantling, reuse.

Background technology

AP1000 nuclear power technology is the safest, state-of-the-art business nuclear power technology in current global nuclear power market, is also Chinese generation Ⅲ nuclear power proprietary technology simultaneously.AP1000 steel dome-shaped becomes superposition mode, needs the special moulding bed of design to meet the requirement of whole site operation.But it is prefabricated and assembled that traditional moulding bed majority integrates, project organization is complicated, take up room large, and the engineering time is long.Therefore need badly and provide a kind of simple and easy flexible, be convenient to the assembled jig frame special of AP1000 dome of restructuring, dismounting, recycling.

Summary of the invention

The technical problem to be solved in the present invention is to provide a kind of splicing accuracy, minimizing use location, space of improving dome, shortens the assembled moulding bed of AP1000 nuclear power dome of construction period simultaneously.

For solving the problems of the technologies described above, the assembled moulding bed of a kind of AP1000 nuclear power of the present invention dome, comprises the concrete foundation along whole circumferential arrangement that supports the inner ring column along whole circumferential arrangement of dome ring beam, the outer ring column along whole circumferential arrangement that supports dome radial girders one end, the support dome radial girders other end.

Between inner ring column, by inner ring crossbeam shaped steel and diagonal brace, fix.

Between the column of outer ring, by outer ring crossbeam shaped steel and diagonal brace, fix.

Inner ring column and column corresponding position, outer ring are fixed by Internal and external cycle crossbeam and Internal and external cycle diagonal brace.

Concrete foundation is along being circumferentially evenly arranged, and quantity is 32.

Inner ring column and outer ring column form by two sections vertically, after dome body is assembled, the upper semisection of inner ring column and outer ring column are removed, and inner ring column is connected by supporting bracket with the lower semisection of outer ring column; Supporting bracket is connected with dome module.

The present invention is meeting under the prerequisite of the assembled requirement of dome unit, and moulding bed material usage is few, easy and simple to handle, structural bolts connected node, and quick detachable easy transportation, jig structure and dome end opening space are larger, can be used for having bad luck, installing of internal module material; Interior construction space is large, and support is not established in centre, and the limitation in the constructing operation of having avoided causing too much because of intermediate supports can effectively shorten the assembled duration of mold and the construction period of dome, improves the assembly precision of dome.

In figure: 1 is outer ring column, 2 is inner ring column, and 3 is that outer ring crossbeam shaped steel, 4 is inner ring crossbeam shaped steel, and 5 is Internal and external cycle crossbeam, 6 for supporting bracket, and 7 is diagonal brace, and 8 is Internal and external cycle diagonal brace, and 9 is dome module, 10 is dome radial girders, and 11 is dome ring beam, and 12 is concrete foundation.

The specific embodiment

Below in conjunction with drawings and Examples, the present invention is further detailed explanation.

Moulding bed installation procedure: measurement unwrapping wire-column unit installation-intercolumniation support and connection on leveling-basis are installed on moulding bed basis.

Outer coil unit embodiment: along being connected with outer ring crossbeam shaped steel 3, diagonal brace 7 by bolt between the outer ring column 1 of whole circumferential arrangement, form and stablize trussed construction, as shown in Figure 2.

Interior coil unit embodiment: along being connected with inner ring crossbeam shaped steel 4, diagonal brace 7 by bolt between the inner ring column 2 of whole circumferential arrangement, form and stablize trussed construction, as shown in Figure 3.

Embodiment between inside and outside circle: outer ring column 1, inner ring column 2 corresponding positions employing bolts and Internal and external cycle diagonal brace 8, Internal and external cycle crossbeam 5 connected modes, form the trussed construction between inside and outside circle column, guarantee the plane stability of hoop framework.

The embodiment of dome and moulding bed: dome radial girders 10 one end are bearing in concrete foundation 12, the other end is bearing on outer ring column 1, forms dome body construction with 11 welding of dome ring beam.Concrete foundation 12 is along being circumferentially evenly arranged, and quantity is 32.Dome ring beam 11 is supported by inner ring column 2.Between basis and steel column, do not establish support, for the accessory module of dome body provides enough assembled spaces.As shown in Figure 4.

Each forms by two sections vertically for outer ring column 1, inner ring column 2, two is intersegmental with bolts, after dome body is assembled, the upper semisection of outer ring column 1, inner ring column 2 to be removed, the lower semisection of outer ring column 1, inner ring column 2 is with bolts with support bracket 6.Support bracket and by bolt, be connected with dome module 9 again, play a supporting role, as shown in Figure 5.
