Description

TECHNICAL FIELD [0001] The present invention relates to a modular unit having cross-sectional cloth information and a modular unit structure using the same,

More particularly, the present invention relates to a modular unit having cross-sectional fabric information and a modular unit structure using the modular unit. More particularly, both sides of the fabric information are formed into a large cross-section and the central portion is formed into a small cross- Sectional shape of the modular unit and the modular unit and the modular unit and the modular unit are coupled with each other through the connecting reinforcing plate at the time of the upper and lower lamination coupling between the modular units, To a modular unit structure capable of increasing the overall lateral resistance.

"Steel Structure Modular Unit Construction" is a technology that systematically transforms high-quality construction to ensure the constant quality and supply to many customers while also recycling resources. In order to achieve this, a box-type steel frame with a high degree of completeness is required to be produced in the factory, and a technique is required to be completed in a short time by a minimum process in the field.

The modular construction of the steel frame unit is less in loss due to lack of factory production and it is the most suitable construction method for reuse and reuse.

Generally, four modular units are formed by combining vertically formed posts and bottom beams connecting top and bottom of columns, respectively.

The column may be provided with a whorl plate having a rectangular steel pipe functioning as a vertical member in the modular unit and hollowed out to form a hollow portion and having a hole formed at an upper end and a lower end thereof. Fabric information and bottom view are composed of various sections, and they are connected to the top and bottom of the column by bolts, welding, etc., and generally have a channel-shaped bent section.

In the conventional modular unit, since the bottom beam and the cloth information are configured to resist gravity load and lateral load at the same time, there is a problem that the design of the load transmission mechanism is not clear and the design is not easy.

In addition, it is difficult to secure a space for bolt fastening due to the narrow beam damping of the bolt connection with the column in the existing modular unit fabric information. Especially, the use of the power tool for high tension bolt fastening such as T / S bolt It is difficult to secure the quality of the bolt fastening part in order to secure the integrity of the upper and lower unit by the structural compensation calculation. .

Also, in a modular unit structure formed by stacking a plurality of conventional modular units horizontally and vertically, bolts between units are directly fastened for joining between modular units, or a plurality of connection reinforcing plates are inserted and fastened by bolts, It is difficult to secure a space for bolt fastening due to the narrow dancing of the beam, and the assembling and disassembly are inconvenient, resulting in poor workability.

As a technique behind the joining portion between the modular units of the present invention, Patent Registration No. 0923637, "Architectural Modular Unit with Reinforced Concrete Ribbon"

The first bolt insertion hole 41 is formed in the center of the wharf 40 so as to be inserted into the incision hole. Shaped reinforcing member 10 is inserted and welded to the column 2, An upper fixing hole lower insertion hole 51 is formed in the flat portion 3a and a lower fixing hole upper insertion hole 50 having a larger diameter than the fixing hole lower insertion hole 51 is formed in the lower flat horizontal portion 4c, The second bolt insertion hole 21 is formed on one side of the first bolt insertion hole 41 so as to coincide with the first bolt insertion hole 41 on the vertical line. And the fixing plate insertion holes 22 corresponding to the inner diameters of the fixture upper insertion holes 50 are formed in contact with the marginal plates 40 so that the first bolt insertion holes 41, An upper conical portion 31 formed in a conical shape and inserted into the insertion hole 21 through a fixing bolt and a cylindrical portion 31 formed at a lower portion of the upper conical portion 31 and having a diameter An upper cylindrical portion 32 having an upper inner cylindrical portion 32 and an upper inner cylindrical portion 32, A position fixture 30 composed of a lower cylindrical portion 33 having a corresponding diameter and a lower conical portion 34 formed in a conical shape below the lower cylindrical portion 33 is inserted into the fixture lower insertion hole 51 Wherein the lower cylindrical portion 33 is inserted and the upper cylindrical portion 32 is inserted into the fixing hole insertion hole 22 of the connecting plate 20 in order. I suggest.

However, in the background art, the upper and lower modular units are combined using the connecting plate 20, which is difficult to maintain the structural stability because it is difficult to increase the lateral force resistance because it merely connects the ends of the columns with each other .

In addition, since the structure of the coupling part is complicated and the bolt fastening part is in the inside of the column when the modular unit is coupled, it is inevitable that the mouse hole is pierced, so that there is a high possibility of local buckling due to the sectional defect of the pillar member, There is a problem in that the bolt fastening is performed inside the mouse hole, so that the bonding and disassembly are inconvenient and the workability is poor.
