Description

  The present invention relates to a building construction method and a building.

  However, in this conventional large module construction method, if many members are assembled in advance as a module, the number of man-hours for assembling the members at the construction site can be reduced. Invited.

  For this reason, since a crane is selected according to the heaviest module, there exists a subject that the use efficiency of a crane is bad and cost also increases.

  In addition, regarding the modules, since standardization (commonization) of the structure is not considered at all, the structures are different among a plurality of modules. Therefore, each time a building is constructed, one product is manufactured for each module. For this reason, for example, when a building having the same structure is constructed a plurality of times, it is difficult to utilize the experience of producing the module produced last time, so that there is a problem that the production efficiency of the module is bad and the production period is prolonged.

  On the other hand, as a result of many years of research on the building construction method for nuclear power plants, the present inventor can construct a building with a composite block modularized by patterning (standardization) of a few numbers, and can solve the above conventional problems. New knowledge was obtained.

  This invention considers such a situation, and the objective is to provide the building construction method and building which can aim at shortening of a construction construction period.

  The building construction method and the building according to the present invention include a step of constructing a floor of the building, and a machine part having at least one of a floor part, a side wall part, and a ceiling part forming a part of the building body. A step of manufacturing a plurality of patterns of composite blocks formed integrally in advance, and a step of loading and arranging the plurality of composite blocks on the floor after the building floor is constructed. Yes.

  According to the present invention, the building construction period can be shortened.

Having the first to sixth pattern composite blocks 31 to 36, which are configured as described above, from the first basement floor (B1F) of the turbine building 1. It is a plane schematic diagram of the example of arrangement of each floor (layer) when arranging up to the fourth floor (4F) and constructing a turbine building 1 having a plurality of layers (floors).

  That is, as shown in FIG. 1, after the floor 2 of the second basement floor is constructed, the composite blocks 3, 3,... Are arranged at predetermined positions on the floor 2 according to a predetermined pattern corresponding to the position. The composite blocks 31 to 36 are respectively carried by a crane (lifter) (not shown) and fixed by stud bolts on the floor 2.

May be joined by an adhesive such as concrete, or may be joined and fixed by a required coupling device such as a joint (not shown).

  Next, the effect of this embodiment will be described.

  As shown in FIGS. 15A and 15B, a construction site 21 is provided near the construction site 20 at the construction site of the nuclear power plant. The construction site 20 includes a reactor building 22, a construction site for the turbine building 1, a storage or action area for the crane 23, temporary storage yards 24a and 24b for construction materials, and module production sites 25a and 25b.

  In addition, the factory site 21 has production sites 26a and 26b, respectively. The conventional production site 26a of the reinforced concrete structure produces modules such as parts, devices, and prefabricated products that are manufactured near the construction site. On the other hand, in the production site 26b according to this embodiment shown in FIG. 15B, the composite blocks 31 to 36 having the first to sixth patterns are mainly manufactured.

  That is, FIG. 15 (A) shows a nuclear power plant construction site according to a conventional construction method in which the reactor building 22 and the turbine building 1 are sequentially raised from the lower layer (lower floor) to the upper layer (upper floor) by a reinforced concrete structure. FIG. 15B shows a layout of the construction site according to the present embodiment.

  As shown in FIG. 15 (B), according to the construction method of the present embodiment, the space of the temporary storage yard 24b for construction materials, etc. is indicated by a broken line rather than the temporary storage yard 24a for construction materials shown in FIG. 15 (A).

  That is, according to the present embodiment, the first to sixth pattern composite blocks 31 to 36 are manufactured in the manufacturing site 26b, and after the manufacturing, the temporary blocks are not temporarily stored in the temporary storage yard 24b such as construction materials. Since the crane 23 directly carries in and is fixed to the turbine building 1 under construction, as shown by the broken line in the figure, the space for the temporary storage yard 24b for this construction material and the number of warehouses can be reduced.

  Further, according to the present embodiment, since the composite blocks 31 to 36 having the first to sixth patterns are manufactured by the manufacturing site 26b and not manufactured by the module manufacturing site 25b, the module is manufactured as shown by a broken line in the drawing. The space of the field 25b can be reduced.

  Furthermore, conventionally, the equipment 11, the pipe 10, the gantry 12, the tray, and the conduit pipe 14 are each carried alone into the turbine building 1 as needed using a large construction crane 23. However, according to the construction method of the present embodiment, these devices are incorporated in advance as the composite block 3 and are carried together as a module into the building, so that the number of times of carry-in can be greatly reduced. In addition, this makes it possible to reduce the man-hours for adjusting the crane 23 and to reduce the risk of operation stoppage due to environmental influences.

Moreover, in this case, it can be carried into the turbine building 1 without depending on the capacity of the crane 23. Furthermore, the crane 23 can be used efficiently by matching the weight of the composite blocks 3, 3,... With the maximum lifting capacity of the crane 23.

  Moreover, by suspending simultaneously with the crane 23 as the composite block 3 which integrated apparatuses, such as the apparatus 11, the piping 10, the mount 12, the tray, and the conduit 14, it occupies most of the man-hours of building construction work. Reduce the man-hours for loading and lifting equipment.

  Further, since the composite blocks 3, 3,... Are assembled at the production site 26b, the number of man-hours at the construction site 20 can be greatly reduced. For this reason, management man-hours can be reduced.

  Further, according to the present embodiment, when the plurality of patterned composite blocks 3, 3,... Are appropriately combined, by burying an embedded object such as the preceding embedded pipe 10a in advance in the wall or floor, The construction period of the preceding burial work can be shortened.

The piping design process 42 can be shortened by the required period α. In FIG. 16, reference numeral 44 indicates the time when the turbine building 1 is started.

  According to the present embodiment, the composite blocks 3, 3,... Are configured and standardized in an optimal pattern for each of a plurality of rooms of the turbine building 1 that is a space in which these are accommodated and installed. Labor saving in the design of the turbine building 1 can be achieved. Moreover, since arrangement | positioning design of an apparatus etc. should just consider the piping which connects rooms, the time concerning this arrangement | positioning design and the piping design process 42 can be reduced significantly.

  Further, since the composite blocks 3, 3,... Are standardized, the current construction process can be assembled using the construction process of the turbine building 1 constructed last time. For this purpose, the master schedule for clearly confirming the critical path, the production schedule of equipment, the submaster schedule for confirming the relevance with on-site construction, and the time for studying the zone-specific processes that characterize the construction of nuclear power plants. Can be shortened.

  Furthermore, as shown in FIG. 17, according to the present embodiment, in the engineering schedule of the process review work at the planning stage of the nuclear power plant, the master schedule review process 45, submaster, The schedule review process 46, the section-specific process review process 47, and the equipment / electric work 48 are provided, but according to the present embodiment, the sub-master schedule review process 46 and the section-specific process review process 47 are required. The period β can be shortened.

  That is, in the sub master schedule examination step 46, the piping systems of these systems are further examined based on the various system configurations examined in the master schedule examination step 45. According to this embodiment, various composite blocks 3, Since the piping system is examined when designing the configurations 3,..., The sub master schedule examination process 46 can be shortened.

  Furthermore, according to this embodiment, when designing the composite blocks 31 to 36 of the first to sixth patterns, the process for each section is examined by examining the relationship between the composite blocks 31 to 36. Therefore, the process of the section-specific process examination process 47 can be shortened.

  FIG. 18 shows a module production schedule for producing the module according to the conventional method shown in Patent Document 1 and the composite block 3 according to the present embodiment as a module and transporting them to the construction site of the turbine building 1 on a required date. Both of them have a production method examination step 49 for examining a method for producing the module or the composite block 3 and a production step 50 for producing the module or the composite block 3.

  A plurality of conventional modules are not patterned (standardized) and are manufactured as a single product, and each time a turbine building 1 is constructed, a plurality of modules are manufactured one by one. In the case of constructing a plurality of times from the second time 51 onward, the production method review step 49 and the production step 50 are newly repeated each time the construction is performed.

  On the other hand, according to the present embodiment, since a plurality of composite blocks 3, 3,... Are patterned in advance into, for example, six types according to the configuration of the turbine building 1, for example, a composite corresponding to the configuration of the turbine building 1 If the turbine building 1 having the same configuration is constructed a plurality of times in the period from the construction order of the turbine building 1 to the completion of construction by making blocks 3, 3,. Both the examination step 49 and the production step 50 can be shortened.

  In addition, according to the present embodiment, for example, composite blocks 3, 3,... Corresponding to the configuration of the turbine building 1 are manufactured in advance, thereby shortening the period from the construction order of the turbine building 1 to the completion of construction. it can. Furthermore, since the composite block 3 is standardized into, for example, 6 types and the number of types is not large, the producer only has to repeatedly manufacture the composite block 3 having the same configuration, thereby improving the production efficiency and the production accuracy. Can do. Further, in the procurement of parts such as the fuselage part and the equipment, the same members can be ordered in large quantities, so that the unit price can be reduced.

  FIG. 19 shows a schedule of the construction stage after the start 52 of the turbine building 1 as an example of the building. According to this embodiment, each process of floor 2 (mat) construction work 53, lower body work 54, and upper body work 55 is provided, as in the conventional method shown in Patent Document 1. Reference numeral 56 indicates the timing of the overhead crane operation 56.

  Here, the lower body refers to a lower floor body below the floor (floor) on which the turbine is disposed, and the upper floor body above the turbine disposed floor (floor) is referred to as an upper body.

  Since the lower body is configured by installing a plurality of composite blocks 3, 3,... That are previously unitized (modularized) at predetermined positions, the work period of the lower body work 54 can be shortened. .

  In addition, although the said embodiment demonstrated the construction method of the turbine building 1 as a building and the turbine building 1 constructed | assembled by this construction method, this invention is not limited to this, A reactor building, a control building, Either a waste treatment building or a service building may be used.

  The reactor building is a reactor pressure vessel (RPV) of a steam generation facility and a building that stores radioactive materials and the like even during an accident as a primary storage facility.

  The control building houses a central control room where operation panels of nuclear power plants are centrally arranged. Depending on the power plant, the central control room is located in a part of the reactor building, in an auxiliary building that is integrated with the waste treatment facility, or in an independent building. It is determined by the shape and size of the reactor building and the shape, size and accessibility of adjacent buildings.

  The waste treatment building contains liquid and solid waste generated in the reactor building and turbine building, and may be a composite building that is integrated with the reactor building. There is also a centralized system that installs only in the main building and processes the waste liquid of multiple units. Since radioactive materials are handled, tanks and processing equipment partitioned by shielding walls are arranged, and its operation panel and cable processing room are also installed in the building.

  The service building is a building that houses facilities for managing access to the radiation control area in the reactor building and the turbine building.
