Background

Recently, as the number of owned cars is rapidly increased, the extension of parking facilities becomes important, and the construction of underground parking lots is gradually increased in order to improve the proximity of buildings and parking spaces and to effectively utilize the parking spaces.

However, unlike large apartment buildings, in urban central areas, buildings are high-rise and dense due to high land prices, and thus, the space for constructing underground parking lots is limited.

In the case of the conventional underground parking lot, an entrance/exit passage for allowing vehicles to enter/exit the underground parking lot is required in addition to a parking floor space for parking the vehicles, and when the underground parking lot is formed of a plurality of floors, an elevating space for moving the vehicles to the parking floors of the floors is required, thereby causing a problem of a decrease in space utilization of the underground parking lot.

Therefore, as disclosed in korean laid-open patent publication No. 10-2001-0048499 (published 2001, 06, 15), in order to maximize the number of cars parked in a limited space, underground parking lot construction in which a plurality of parking floors are radially formed along a vertical hole wall surface inside a circular vertical hole, space utilization efficiency of an underground parking space is improved by providing an elevator at a center portion of the vertical hole, is gradually expanded.

In order to form the underground parking lot as described above, when constructing the vertical hole, a downward prefabricated segmental vertical hole construction method is applied as follows: in order to shorten the time consumed for setting a formwork for forming an inner wall of a vertical hole and curing concrete, arch-shaped precast blocks are previously manufactured, and segments formed of a ring-shaped block assembly in which a plurality of precast blocks are connected in a lateral direction are inserted and stacked on an excavated surface of the vertical hole at an underground parking lot construction site, thereby forming the inner wall of the vertical hole.

In the process of descending the stacked sections, the inclination of the vertical hole wall surface and the fine gap or displacement between the section stacked connection parts occur due to the uneven descending of the section stacked body resulting from the difference in soil texture constituting the excavated ground, which leads to the construction defects that the vibration resistance of the underground parking lot and the air tightness between the section stacked connection parts are reduced, the structural stability of the underground parking lot is reduced, water leakage occurs through the connection parts, and the support structure of the underground parking lot is constructed together when the parking floors are formed along the inner walls of the section stacked body after the wall surface construction of the underground parking lot according to the down-type prefabricated section vertical hole construction method is completed.

As a prefabricated vertical core structure and a construction method thereof of korean patent laid-open publication No. 10-2214779 (granted on 04/02/2021), a support structure for an underground parking lot is formed in a form of a partition as follows: when the parking floors are formed in order from the lowest floor to the upper floor of the underground parking lot, the wall surface supporting structure of the underground parking lot is arranged at the center of the underground parking lot from the bottom of the vertical hole to the upper direction according to the floor height of the parking floor in construction, so that the parking floors of each floor can be supported, and various underground facilities can be arranged in the underground parking lot.

Further, as a method for constructing a circular underground parking lot disclosed in chinese patent publication No. 1122196335 (published 2021, 01/08), the following support structure for an underground parking lot is disclosed: a column is provided in the center of the segment stacked body along the height direction of the vertical hole, and each column is fixed by a steel beam.

However, in the partition type support structure, in the process of constructing the parking floors of each floor in order from the lowest floor of the underground parking lot toward the upper direction and constructing the support structure, construction delay may occur, and in the support structure passing through the column and the steel beam provided at the center of the vertical hole, it is more difficult to provide the column as the depth of the underground parking lot is deeper, and buckling of the column is likely to occur due to the floor supported by the column and the load of the vehicle mounted thereon, and thus there is a need for improvement of the wall surface support structure of the underground parking lot which can further improve the construction efficiency and the structural stability of the underground parking lot.

In addition, in order to improve the transportation efficiency of the logistics, hubs (hubs) are formed in each main area, the logistics containers are temporarily stored in logistics warehouses of the hubs and then are individually transported to destinations, mass transportation of the logistics on sea or land is mainly completed by standardized containers, and the logistics containers temporarily stored at the departure or destination are stored in container yards.

The container yard or the general logistics warehouse is provided with unloading equipment such as a crane or a forklift which can load or unload logistics containers or cargos such as ships or transport vehicles to or from the ships or transport vehicles, the utilization efficiency of the storage space is improved by stacking the cargos such as containers into a plurality of layers by the unloading equipment, and the stacking height of the cargos such as containers is limited to prevent the occurrence of economic loss or safety accidents due to damage or collapse of the containers or packages for protecting the cargos caused by the loads of the stacked cargos, thereby limiting the time for securing the storage space of the cargos.

In particular, when storing goods such as a logistics container in a conventional manner in a container yard or a logistics warehouse, it is necessary to move all the goods stacked on the top of the corresponding goods in order to sort and transport specific goods located on the bottom of other goods stacked on the top, which is difficult in sorting, storing, and transporting of logistics, and thus there is an increasing need to provide a logistics warehouse capable of easily sorting, storing, and transporting goods while improving the availability of goods storage space of a logistics container or the like.

On the upper portion of the floor 500 of each floor, a plurality of floor modules 40 are disposed on each floor 500 module, and the floor modules 40 having two or more floors (floor) formed thereon are installed on the floor 500 in a state where the floor modules 40 are assembled, or the floor modules 40 in an unassembled state are transferred to each floor 500 and then assembled.

In this case, in the case of constructing the underground warehouse 2 by the downward construction method of the segment 10 according to the conventional method, floors are sequentially formed from the lowermost layer of the underground warehouse 2 toward the upper direction, and in order to support the floors and install various underground facilities during the floor construction, a support structure formed of partitions is simultaneously constructed in the center portion of the underground warehouse 2 from the bottom of the vertical hole 1 toward the upper direction according to the floor height of the floor under construction, and the construction time of the underground warehouse 2 increases during the construction of the partition structure.

Therefore, in the present application, the construction processes of the floors of the underground warehouse 2 and the partition structures for supporting the floors according to the conventional method are simplified by providing the modularized columns, beams, and floors of the stack of the support sections 10, and the floors of a plurality of floors can be formed at the same time by providing one floor module 40, so that the construction time of the underground warehouse 2 can be greatly shortened.

The elevator 20 is provided in the center of the underground warehouse 2, and the elevator 20 is rotatably configured through an elevator opening 510 formed in the center of the floor 500 of each floor.

The elevator 20 is configured to move a vehicle, a physical distribution container, other goods, or the like loaded on the ground of the underground warehouse 2 to an empty floor entrance of the floor module 40 by lowering and rotating the vehicle, the physical distribution container, or the like to be loaded on the ground into the underground warehouse 2, and then to load the vehicle, the physical distribution container, or the like on the upper part of the floor or to move the vehicle, the physical distribution container, or the like loaded on the underground warehouse 2 to the floor entrance where the goods are located, thereby loading the stored load on the elevator 20 and moving the load to the ground.

As shown in fig. 13, the auxiliary beam 410 is provided at the center of each of the first and second connection beams 220 and 320 disposed to face each other on a layer-by-layer basis, and the first and second connection beams 220 and 320 can be connected to each other, and the auxiliary beam 410 can be provided in all spaces between the adjacent first and

second support columns

200 and 300, or in a part of the spaces between the first and

second support columns

200 and 300 so as to form a predetermined angle.

One end of the auxiliary beam 410 protrudes a predetermined length in the center direction of the vertical hole 1, and a ring beam 420 having a ring shape is connected to the end of each protruding auxiliary beam 410.

The auxiliary girder 410 is formed in a more stable and stable modular structure of the underground warehouse 2 by fixing the first connection girder 220 and the second connection girder 320 to each other, so that the maximum load of the preserved items loaded on the upper portion of the floor 500 can be increased, the ring girder 420 supports the side portion of the lifter 20 provided at the center of the underground warehouse 2, has a relatively narrow width compared to the height, prevents the deformation or damage of the lifter 20 structure, which is easily buckled, and prevents the shaking of the lifter 20 structure when the preserved items of a high load are transferred, thereby further improving the operation stability of the lifter 20.

As shown in fig. 14 and 15, the damper support rod 230 may be attached to the outer circumferential surface of the connection portion of the first connection beam 220 or the connection portion of the third connection beam 400 of the first support column 200 of each layer, the end of the first connection beam 220 or the third connection beam 400 connected to the damper support rod 230 may be disposed on the upper surface of the damper support rod 230 at a predetermined interval from the outer circumferential surface of the first support column 200, and may be connected to the first support column 200 in a state of not being fixed thereto, thereby generating play between the first support column 200 and the first connection beam 220 or the third connection beam 400.

In this case, when an external force is applied due to an earthquake or the like, the stack of the segments 10 constituting the wall surface of the underground warehouse 2 and the first support column 200 are spaced apart from each other, and thus the modular structure constituted by connecting the support columns and the beams moves independently of the segments 10.

Accordingly, the load of the storage loaded on the module structure and each floor 500 does not directly act on the segment 10, and the connection between the blocks 100 constituting the segment 10 is prevented from being disconnected or the inclination or displacement is prevented from occurring between the stacking surfaces of the segments 10, thereby improving the structural stability of the stacked body of the segments 10 in the underground warehouse 2.

In particular, the modular structure realizes independent movement between the two structures of the connection body of the first column 200 and the first connection beam 220 and the connection body of the second column 300 and the second connection beam 320 by the play between the first column 200 and the first connection beam 220 or the third connection beam 400, and generates a damping effect due to the play between the first column 200 and the first connection beam 220 or the third connection beam 400 when an external force is applied due to an earthquake or the like.

Compared with the integrated module structure in which the first and

second pillars

200 and 300, the first and second connection beams 220 and 320 and the third connection beams 400 are fixed to each other, the module structure in which the damper support rod 230 is applied to the damper structure can reduce vibration and impact applied to the module structure by reducing the shaking amplitude of the integrated module structure, and thus, vibration resistance of the underground warehouse 2 can be improved and structural stability can be further improved by more easily dispersing the vibration and impact of the module structure.

Further, as shown in fig. 16, in order to improve the damping performance of the damper support rod 230, a damper guide 231 is installed at the upper portion of the damper support rod 230, and the first damper 221 or the second damper 403 is formed at the lower portion of the distal end of the first connection beam 220 or the third connection beam 400 connected to the upper portion of the damper support rod 230, respectively, whereby the first damper 221 or the second damper 403 can be brought into contact with the upper surface of the damper guide 231.

In this case, a concave groove having a parabolic shape protruding downward may be formed on the upper surface of the damper guide 231, the lowest point of the concave groove may be disposed concentrically with the outer circumferential surface of the first support 200, and a protrusion having a protruding surface may be formed on the lower surface of the first damper 221 or the second damper 403.

Accordingly, as shown in fig. 17, when play occurs between the first support column 200 and the first connection beam 220 or the third connection beam 400 due to an external force, the lowest point of the projection surface of the first damper 221 or the second damper 403 is separated from the lowest point of the groove of the damper guide 231, and the lowest point of the projection surface of the first damper 221 or the second damper 403 is returned to the lowest point of the groove of the damper guide 231 again due to the load of the floor 500 and the loaded storage, thereby more rapidly generating a damping action.

When an excessive external force acts on the modular structure, the free distance is restricted while the tip of the first connection beam 220 or the third connection beam 400 contacts the outer circumferential surface of the first strut 200, and the first strut 200 functions as a stopper to prevent the first damper 221 or the second damper 403 from being detached from the damper guide 231.

In particular, in the case of a structure reflecting a vibration-proof design, when deformation or separation occurs between structural material connecting portions of pillars, beams, etc., the stability of the structure can be greatly reduced, and in the modular structure of the underground warehouse 2 of the present invention, when an external force is applied due to an occurrence of an earthquake, etc., the movement between the first pillars 200 and the first connection beams 220 or the third connection beams 400 prevents the deformation of the connecting portions between the pillars and the beams, and the connecting portions of the modular structure moving through the damper guides 231 can be returned to their original states, thereby greatly improving the vibration-proof performance and durability of the underground warehouse 2.

An upper plate 520 constituting an upper cover structure of the underground warehouse 2 may be provided at upper ends of the first and

second supports

200 and 300 disposed at the uppermost end of the underground warehouse 2, and an outer circumferential surface diameter of the upper plate 520 is preferably greater than an outer circumferential surface diameter of the segment 10.

A section fixing beam 521 for fixing the uppermost end of the section 10 may be formed to protrude in a ring shape on the lower surface of the upper plate 520, and the section fixing beam 521 may be formed of an inner fixing beam 522 in a ring shape for fixing the inner circumferential surface of the upper end of the section 10 and an outer fixing beam 523 in a ring shape for fixing the outer circumferential surface of the upper end of the section 10, thereby preventing a gap from occurring between the blocks 100 disposed at the upper end of the section 10 or a separation of the connection portion from occurring, and thus, the structural stability of the constructed underground warehouse 2 may be further improved.

Also, at least one passageway 30 may be formed between the facing first and

second supports

200 and 300, and an emergency staircase or escalator or elevator for moving between floors may be provided at the passageway 30.

As shown in fig. 20, the third connection beam 400 provided at a position where the channel 30 is formed may be formed in two with the connection end branch (bridging) of the first pillar 200, and the channel 30 may be formed between spaces of the branches of the third connection beam 400.

The third connection beam 400 of the branched form forms a frame for setting the passageway 30 of the emergency staircase or escalator or lift, so that the construction time of the passageway 30 of the underground storehouse 2 can be shortened.

The underground parking lot construction method using the vertical hole of the prefabricated segment of the downward type according to the embodiment of the present invention, which is constructed in the above manner, includes: a first step S10 of forming a wall surface of the underground warehouse 2; a second step S20 of setting a pillar and beam module at the lowermost end; a third step S30 of additionally providing pillars and beam modules to form a plurality of layers; a fourth step S40 of filling concrete into the inner space of the column; a fifth step S50 of providing a floor slab 500; and a sixth step S60 of setting the floor module 40.

In the first step S10, a ring-shaped sheath (shoe) for protecting the lower surface of the lowermost segment 10 is disposed at the vertical hole 1 position, and the lowermost segment 10 of the ring shape is combined with the upper portion of the sheath, the segment 10 being formed by connecting a plurality of prefabricated arch blocks 100 in the lateral direction (S11).

When the coupling and arrangement between the sheath and the lowermost segment 10 are completed, the bottom surface of the vertical hole 1 in which the sheath is arranged is excavated to move the sheath and the segment 10 downward (S12), and when the bottom surface of the vertical hole 1 is excavated, the sheath and the segment 10 are simultaneously moved downward by the self weight of the sheath and the segment 10.

Thereafter, the process of moving the laminated structure downward according to the section 10 excavating the bottom surface of the vertical hole 1 and adding the laminated section 10 is repeatedly performed to form the wall surface of the underground warehouse 2 (S13).

In this case, when the stacked body of the segments 10 cannot be smoothly moved downward due to friction between the excavation surface of the side surface of the vertical hole 1 and the segments 10 or the stacked body of the segments 10 is unevenly lowered due to difference in soil properties constituting the ground and is inclined and sunk, the force for pressurizing the upper portion of the topmost segment 10 is adjusted by a plurality of pressers which are disposed at the entrance of the vertical hole 1 at predetermined intervals to uniformly lower the stacked body of the segments 10.

The specifications of the above-described segments 10 or blocks 100 vary according to the size or kind of the contents stored in the underground warehouse 2, and the soil condition of the ground forming the underground warehouse 2 or the number of blocks 100 constituting each segment 10 may also vary according to the shape which differs depending on the connection or fastening manner between the blocks 100.

In the case where the underground warehouse 2 is used as an underground multi-storied parking lot which is one of the embodiments of the present invention, specifications and the number of connections of the blocks 100 and the segments 10 according to the number of vehicles which can be parked on each parking floor of the parking lot are shown in the following table.

TABLE 1

Furthermore, the floor concrete is poured into the bottom surface of the vertical hole 1, one or more catch basins are formed at the edge of the inner bottom surface of the underground warehouse 2 into which the floor concrete is poured, and a porous drain pipe (perforated drain pipe) may be provided along the outer peripheral surface of the bottom surface of the segment 10 outside the wall surface of the underground warehouse 2.

The water collecting ditch and the porous drain pipe are connected to the water collecting well through the water collecting pipe, rainwater flowing into the inside and the outside of the bottom surface of the underground warehouse 2 through the water collecting ditch and the porous drain pipe is collected in the water collecting well, and water collected in the water collecting well is discharged to the sewer pipe through the pump, so that flooding in the underground warehouse 2 is prevented.

In the second construction step S20, the bottommost support columns and the beam modules are installed on the upper portion of the ground concrete of the ground of the vertical hole 1, the plurality of first support columns 200 formed of a hollow tube are arranged at a predetermined angle so as to be close to the inner arcuate surface of the stacked segment 10 (S21), and the plurality of second support columns 300 formed of a hollow tube are installed at a predetermined interval from the first support columns 200 in the central direction of the vertical hole 1, thereby forming an angle equal to the arrangement angle of the first support columns 200 (S22).

Upper side surfaces facing each other of the first columns 200 disposed adjacent to each other of the first columns 200 of the ground concrete are connected to each other by the first connection beam 220 (S23), upper side surfaces facing each other of the second columns 300 disposed adjacent to each other of the second columns 300 are connected to each other by the second connection beam 320 (S24), and the upper portions of the adjacent first columns 200 and the second columns 300 disposed at the same angle are connected to each other by the third connection beam 400 (S25).

In the third construction step S30, the first support column 200 is additionally connected to the upper portion of the first support column 200 installed on the ground concrete surface in a plurality of layers along the height direction of the vertical hole 1 to form a first support column 200 column (S31), and the second support column 300 is additionally connected to the upper portion of the second support column 300 installed on the ground concrete surface in a plurality of layers along the height direction of the vertical hole 1 to form a second support column 300 column to have the same height as the first support column 200 column (S32).

Upper side surfaces of the first pillars 200 arranged adjacent to each other in each layer of the additionally arranged first pillars 200 are connected to each other by the first connection beams 220 (S33), upper side surfaces of the second pillars 300 arranged adjacent to each other in each layer of the additionally arranged second pillars 300 are connected to each other by the second connection beams 320 (S34), and the adjacent first pillars 200 arranged opposite to each other and additionally arranged to form the same angle are connected to upper portions of the second pillars 300 by the third connection beams 400, respectively (S35).

The steps (S21 to S25) of installing the first support column 200, the second support column 300, the first connection beam 220, the second connection beam 320, and the third connection beam 400 may be performed sequentially or simultaneously, and the steps (S31 to 35) of additionally installing the first support column 200, the second support column 300, the first connection beam 220, the second connection beam 320, and the third connection beam 400 may be performed sequentially or simultaneously.

In this case, the components are standardized to modularize the first column 200, the second column 300, the first connection beam 220, the second connection beam 320, and the third connection beam 400, and when the second construction step S20 or the third construction step S30 is performed, the connection parts of the modularized first column 200, the second column 300, the first connection beam 220, the second connection beam 320, and the third connection beam 400 are assembled and connected in advance outside the vertical hole 1, and then moved to the inside of the vertical hole 1 to connect the connection parts of the modules, thereby reducing the time required for the column and beam installation process.

In the third step S30, a step (S36) of providing the auxiliary beam 410 and a step (S37) of providing the ring beam 420 are added to the formed column and beam structure, respectively.

Before the first connection beam 220 or the third connection beam 400 is connected to the first pillar 200(S33, S35), the damper support rod 230 may be attached to the outer circumferential surface of the connection portion of the first connection beam 220 or the third connection beam 400 of the first pillar 200 (S31 a).

When the first connection beam 220 or the third connection beam 400 is connected to the first support column 200(S33, S35), the distal end of the first connection beam 220 or the third connection beam 400 is provided on the upper surface of the damper support rod 230 so as to be spaced apart from the outer circumferential surface of the first support column 200 by a predetermined distance, and when an external force is applied due to an earthquake or the like, the first support column 200 and the support column and beam module structure fixed to each traveling connection beam move independently to generate a damping action.

In this case, the following construction can be selectively performed: the third connection beam 400 is spaced apart from the first column 200 to allow only play between the third connection beam 400 and the first column 200 in a state where the first connection beam 220 and the first column 200 are fixed to each other, or the first connection beam 220 is spaced apart from the first column 200 to allow only play between the first connection beam 220 and the first column 200 in a state where the third connection beam 400 and the first column 200 are fixed to each other, or the first connection beam 220 and the third connection beam 400 are spaced apart from the first column 200 to allow simultaneous play between the first connection beam 220 and the third connection beam 400 and the first column 200.

In the case where the third link beam 400 and the first link beam 200 are configured to play only with each other, the first support column 200 and the first link beam 220 for fixing the first support column 200 form an outer column and beam module structure, and the second support column 300 and the second link beam 320 for fixing the second support column 300 form an inner column and beam module structure, so that the outer column and beam module structure and the inner column and beam module structure independently move to each other, thereby generating a damping effect.

In the case where the first and

second support columns

200 and 300 and the second and third connection beams 320 and 400 for fixing the first and

second support columns

200 and 300 are configured to generate the play only between the first and second connection beams 220 and 200, the first and

second support columns

200 and 300 form a column and beam module structure, and when the column and beam module structure is deformed or inclined by an external force, the play of the first support column 200 is generated according to the movement of the adjacent first support columns 200, which is close to or spaced apart from each other, to generate the damping action.

When the first and third coupling beams 220 and 400 are constructed such that the play simultaneously occurs between the first support column 200, the movements of the two types of the above-described support column and beam module structures compositely occur, thereby generating a damping effect.

In order to prevent the structural stability of the column and beam module structure of the underground warehouse 2 from being lowered by the damping structure spaced between the first connection beam 220 or the third connection beam 400 and the first support column 200, the damping structure using the damper support rod 230 may be applied only to the first support column 200 of the lower support column, which has relatively little shaking when an external force is applied due to an earthquake or the like, and the damping structure using the damper support rod 230 may not be applied to the first support column 200 of the lower support column.

In particular, as shown in fig. 18, in order to prevent the composite damping action between the first and third connection beams 220 and 400 and the first column 200 from excessively increasing the travel distance and degrading the structural stability of the column and beam module structure of the underground warehouse 2, the center portions of the first and second connection beams 220 and 320 disposed to face each other may be fixed by the third connection beam 400.

The groove of the parabolic shape protruding downward formed on the upper surface of the damper guide 231 attached to the damper support rod 230 is disposed such that the lowest point is concentric with the outer circumferential surface of the first column 200, and when the first or

third connection beam

220 or 400 moves closer to or away from the first column 200 due to play between the first or

third connection beam

220 or 400 and the first column 200, the first or

second damper

221 or 403 is separated from the lowest point of the groove and the connection position of the first or

third connection beam

220 or 400 is increased.

The load of the floor slab 500, the floor module 40, and the loaded storage disposed on the upper portion of the first coupling beam 220 or the third coupling beam 400 is a force not applied to the lower portion of the first coupling beam 220 or the third coupling beam 400 whose coupling position is increased by the damping action, the force is a restoring force, and the first damper 221 or the second damper 403 moves to the lowest point position of the groove along the curved surface of the damper guide 231 by the restoring force, thereby maintaining the spaced interval between the first coupling beam 220 and the third coupling beam 400 and the first pillar 200.

Further, the passage 30 provided with the emergency staircase, the escalator, or the elevator for moving between the floors may be formed between the first support column 200 and the second support column 300 facing each other, and when the underground warehouse 2 is used as a cargo storage warehouse such as an underground multistory parking facility or a logistics container, the longitudinal direction of the cargo such as vehicles or containers is radially arranged from the elevator 20 in order to secure a storage space and easily use the elevator 20.

Thus, it is preferable that a space not storing the goods such as vehicles or containers is formed outside the inner wall direction of the section 10 of the underground warehouse 2 constituting the circular sectional structure, and the passage 30 is formed in the space not storing the vehicles or the goods.

When the third connection beam 400 is connected according to the second step S20 or the third step S30 in order to form the passage 30 (S25, S35), the third connection beam 400b may be applied to a portion where the passage 30 is formed, and the end of the third connection beam 400b in the direction of connecting to the first pillar 200 may be branched into two.

The respective ends of the branches of the third connection beam 400b are connected to the first connection beam 220, respectively, the first connection beam 220 is connected to both sides of the first support column 200 to form the passage 30 between the spaces of the branches of the third connection beam 400b, and the third connection beam 400b in the branched form forms a frame of the passage 30, thereby omitting an additional frame structure setting process for constructing the passage 30 and thus shortening the construction time of the passage 30 of the underground warehouse 2.

In the fourth construction step S40, concrete is filled into the space formed inside the column of the first support column 200 and the column of the second support column 300, and the concrete filled in the hollow space of the first support column 200 and the second support column 300 forms a steel pipe concrete structure.

Accordingly, the first and

second support columns

200 and 300 can be manufactured as steel pipes having a diameter of usually 500mm to 1200mm in order to secure the rigidity of the steel pipe concrete structure, and the diameters of the first and

second support columns

200 and 300 can be adapted to have a size different from the above-described specification according to the load of the upper structure 3, not only as a modular frame structure of the underground warehouse 2 used as the first and

second support columns

200 and 300, but also as a foundation of the upper structure 3 such as a building constructed above the underground warehouse 2.

In particular, when the depth of the underground warehouse 2 is increased, the first and

second columns

200 and 300, which are formed by being connected in the height direction of the vertical hole 1, have a column shape having a length longer than the thickness thereof, and thus have a structure in which buckling (buckling) is easily generated.

Therefore, in the construction method of the present invention, after the first column 200 columns adjacent to each other are fixed to each other by the first connecting beam 220 and the second column 300 columns adjacent to each other are fixed to each other by the second connecting beam 320, the first column 200 columns and the second column 300 columns arranged to face each other are fixed to each other by the third connecting beam 400, and thus, the deformation of the connecting portion between the columns of each column in the horizontal direction is suppressed, and buckling of the column columns is prevented.

Further, the first support column 200 and the second support column 300 having a relatively shorter length than the support column are connected to each other by a plurality of layers to form a steel pipe concrete structure in which concrete is filled in the hollow portions of the first support column 200 and the second support column 300, thereby forming the integrated first support column 200 and second support column 300, so that the length of the first support column 200 and second support column 300 can be easily secured according to the depth of the underground warehouse 2, and the support column which is easily deformed and damaged can be more easily installed by the lightweight hollow structure and the split structure of each of the first support column 200 and the second support column 300 having a length longer than the thickness.

In a fifth step S50, a floor 500 is installed on the upper surface of the first and second coupling beams 220 and 320 for each floor of the column and beam module structure formed in the fourth step S40, and a space for installing the lifter 20 is formed by the lifter hole 510 formed in the center direction of the vertical hole 1 of each floor 500.

Also, when the fifth step S50 is executed, the following procedure S51 may be added: an upper plate 520 constituting an upper cover structure of the underground warehouse 2 is provided at upper ends of the first support column 200 and the second support column 300 disposed at the uppermost end of the underground warehouse 2.

The upper plate 520 forms the bottom surface of the upper structure 3 constructed on the upper portion of the underground storehouse 2 at the same time as the upper cover of the underground storehouse 2, and each pillar column of the underground storehouse 2 and the upper plate 520 function as a frame structure of the upper structure 3, whereby the frame construction cost of the upper structure can be reduced.

In this case, it is preferable that upper beams 3b be provided between the upper plates 3c of the respective floors to support the upper plates 3c of the respective floors constituting the upper structure 3, and the upper beams 3b be disposed to face the upper portions of the columns of the first or

second columns

200 and 300 of the underground warehouse 2 to ensure the stability of the frame structure supporting the upper structure 3.

The segment fixing beam 521 formed at the lower portion of the upper plate 520 fixes the inner and outer circumferential surfaces of the upper end of the topmost segment 10 constituting the wall surface of the underground warehouse 2 by the inner fixing beam 522 and the outer fixing beam 523, respectively, and prevents a gap or separation from occurring between the blocks 100 constituting the segment 10, thereby improving the stability and vibration resistance of the wall surface structure of the underground warehouse 2.

In the sixth step S60, the floor module 40 is installed on the floor 500 of each floor installed in the fifth step S50, and the floor module 40 is disposed in the space between the first column 200 and the second column 300 disposed in each floor.

Each floor module 40 forms floors of more than two floors, and floors of a plurality of floors are formed simultaneously by arranging one floor module 40, so that the construction time of the underground warehouse 2 can be greatly shortened.

After the formation of the column and beam module structure inside the underground warehouse 2 of the fourth step S40 is completed, the lifter 20 may be provided together with the execution of the fifth step S50 or the sixth step S60.

The embodiments of the present invention have been described with reference to the above, but it is understood that those skilled in the art to which the present invention pertains may implement other embodiments without changing the technical idea or essential features of the present invention.

It should be understood, therefore, that the above-described examples are illustrative in all respects and not restrictive, that the scope of the present invention described in the above detailed description is shown by the scope of the invention, and that all modifications and variations derived from the meaning and scope of the invention claimed and the concept equivalent thereto are included in the scope of the present invention.
