Description

Modular Unit and Modular Structure Constructed Using Them {MODULAR UNIT AND MODULAR CONSTRUCTION USING THE SAME}

The present invention relates to a modular unit and a modular structure constructed using the same, and more particularly, has a member shape that facilitates the manufacture of the modular unit, and improves the assembly workability of the module. It relates to a modular unit having a modular bonding structure for easy disassembly and assembly and a modular structure constructed using the same.

In general, a modular building refers to a structure in which a box-shaped modular unit in which a finish of structures, interior and exterior materials, and facilities is installed at a factory is manufactured at a factory, and then transported to a site to be laminated and assembled.

Since most of these buildings are manufactured at factories, they can produce products of the same quality without being influenced by the skill of the field manpower, the environmental conditions on the site, and the climate change, compared to the general construction method.

As described above, the modular building is widely applied to various types of buildings in Europe, Japan, and the United States because it is easy to improve quality through assembling and disassembly through factory production.

1 is a perspective view of a modular unit 10 of a conventional modular building, and FIG. 2 is a perspective view illustrating a perspective view of a modular structure 20 assembled using the same and a module junction.

As shown in the example shown in Figure 2, the conventional modular building is the bottom plate fabrication work due to the shape of the beam when fabricating the bottom plate after assembling the bottom plate beam to form the floor structure by using the c-channel or square steel pipe Not easy

In addition, the conventional modular building is basically fastened at the pillar of the upper and lower modules when the modular unit 10 is stacked, and the upper module floor beams and the fabric information of the lower module is not fastened, so that the upper module floor loads load all of the upper module floor beams. Supporting and lower module fabric information only plays a role in module transportation and lifting, and does not play a structural role after assembly, so the utilization of members is inefficient.

In addition, in the conventional modular building, the pillar and the beam are joined by end plate welding, and are assembled by fastening upper and lower end plates at the end of the pillar with bolts. However, the fastening method using the end plate has a problem in that the end plate is to be welded to the pillar member to increase the production period and cost by increasing the weld.

In addition, there is a need for a module-to-module connection in consideration of the biaxial structure of disassembling, disassembling, moving to another place, which is an advantage of the modular unit.

Furthermore, in the case of the modular structure, not only the joints between the upper and lower units, but also the beams between the left and right units must be joined to increase the structural integrity between the units, thereby increasing the bonding force. There is a problem that the coupling force between the beams of adjacent joining units is reduced by fastening only.

In addition, the conventional modular building has a problem in that the logistics cost is high because the special device must be additionally installed in the module at the time of transportation and transported after the new outer packaging.

The present invention was created in view of the above-mentioned problems in the prior art, and first, to improve the beam cross-section and shape of the conventional modular building to facilitate the work of the floor plate structure and assembly work modular factory manufacturability and field construction The purpose is to increase.

In addition, the present invention, unlike the conventional laminated box unit system when assembling two upper and lower modular units, a double beam integrated modular unit to suppress the deflection and vibration of the module and increase the resistance to the lateral force and using the same In providing a modular structure.

In addition, the present invention is to provide a modular unit and modular structure that is configured to facilitate the bonding and separation of the module by assembling the upper and lower pillars using the connector, the field construction of the modular building is simplified.

In addition, the present invention is to provide a unit that improves the biaxial performance, which is an advantage of the modular unit by simplifying the assembly and separation of the joint by using the connector.

In addition, the present invention is to provide a unit that can be combined with the left and right as well as the left and right joints of the module by using the left and right integral connector for bonding between the left and right units when joining using the connector.

In addition, the present invention is to provide a unit having a module-to-module coupling structure that can be used in the corner casting and lashing system during transportation is not required to install a separate equipment, the coupling force between the modules of the module is increased and easy to assemble.

In addition, in order to solve this problem, the steel material can be further improved by applying the structural structural to Jinjin steel (SN steel) and TMCP steel.

The present invention as a means for achieving the above object, in the modular unit constituting a modular structure; Eight beams, four pillars, and one bottom plate dry construction on the bottom beam to form a square shape, and fastening the bottom plate and the bottom beam while connecting and fixing the fabric information of the bottom beam of the upper module and the lower module Beam connector; A pillar connector configured to connect the pillars of the upper module and the pillar of the lower module and the left and right modules to be fixed, wherein the open side of the section steel constituting the short side beam of the modular unit faces the bottom plate, The open side of the section steel constituting the long side beam of the modular unit is arranged to face the bottom plate direction, the bottom plate is fastened to the bottom beam by the beam connector is characterized in that located on the lower flange of the long side beam Provide a modular unit.

According to the present invention, the following effects can be obtained.

First, by providing improved beam cross-section and shape, it is easy to work on the bottom plate structure and assembly, and improves the workability of dry floor plate installation work.

Second, by integrating the double beams, the structure of the lower module, which does not play a structural role in the existing modular unit, can be used structurally, resulting in a light weight of the frame. Although low, the present invention can achieve the effect of increasing the resistance against lateral force by fastening not only the pillar but also the upper and lower sidewalks, and suppressing the deflection and vibration of the floor beam.

Third, the pillar joining portion having improved workability is configured to facilitate the joining and detachment of the module by assembling the pillar using a connector, thereby simplifying the field construction of the modular building and shortening the air.

Fourth, when assembling the upper and lower pillars using the connector, the upper part of the connector is not bolted, but simply plugged into the mounting type to minimize the fastening work while maintaining the position of the column, thereby simplifying assembly and disassembly work for the biaxial shaft.

Fifth, the connector provides a horizontal connection plate for joining the left and right modules, thereby combining the left and right modules has the effect of improving the structural integrity between the units.

Sixth, it is not necessary to install separate equipment for transportation, so transportation is convenient and logistics cost can be reduced, and the coupling force between units is increased by applying the fastening structure that is connected by bolts between adjacent units through pillar coupling holes and complementary coupling holes. Increased and easy to assemble
