Description

Column-beam coupling structure and column-beam construction method using a coupling assembly having a flange coupling part

The present invention relates to a coupling structure of a building structural member, and more particularly, to a pillar-beam coupling structure for connecting a beam or a pillar with respect to a pillar.

Many columns and beams are required in the construction of a building. Columns and beams are made of steel or a mixture of concrete and steel. Columns, for example, are made of steel or a composite of concrete and steel.

After these columns and beams are connected to each other to form the framework of the building, the building can be constructed.

In this way, many columns and beams are used in the construction of a building, and various technologies for the joint are known in order to secure structural safety by designing the joint that can express the performance of each member.

In addition, as the frequency of earthquakes in Korea increases, joints with seismic resistance of buildings are required. In the case of connecting a column and a beam by bolting with excellent ductility in the construction of a joint made of steel, it is difficult to access the joint or joint of a closed cross-sectional structural member such as a square steel pipe in both directions, so it is difficult to fasten the existing high tension bolts. there is However, the quality of welded joints varies greatly depending on the skill level of skilled workers, and accordingly, the performance of the joint is greatly affected, and there is a problem that it can lead to brittle fracture under the influence of repeated loads during earthquakes, so there is a problem of weakness in seismic joints.

Currently, the construction industry is increasing the proportion of factory production to reduce the effect of the amount of work that varies depending on the weather or surrounding conditions to improve labor productivity. There is a shortage of skilled manpower in the country, and technology development is required to prevent the deterioration of quality and labor efficiency.

In consideration of this situation, a technology capable of stably and firmly coupling the column-beam coupling part, as well as excellent structural performance and simplification of the manufacturing process, is required.

In Korea, the square steel pipe column and steel beam joint are joined through the diaphragm (outer, inner, penetrating) type due to the closed cross-sectional properties of the square steel pipe.

Also, in the case of steel structure construction, if the member length on the design document exceeds the transportable length, a joint is required. In the case of H-beams at column joints, bi-directional access is possible, so high-tensile bolts are used to join, but in the case of closed cross-section members, in-situ welding is generally performed. Sparks generated during welding can cause fire accidents because there are many flammable substances around the construction site.

In column materials, steel with a closed cross-section, such as a square-shaped steel pipe, has higher structural performance than H-beams, so it is possible to reduce the amount of steel and to reduce the finished area. Therefore, it is necessary to detail the joint to solve the problem that may occur when joining or splicing steel with a closed cross-sectional shape.

Since steel column members can express high performance by supplementing the compressive force by bonding with concrete, they are recently applied to long-span and high-rise buildings or where high performance is required to secure the inter-span distance. In the case of a closed cross-section member, it is suitable for filling the concrete inside because it can replace the formwork, but the horizontal diaphragm required to prevent out-of-plane deformation has a problem in that the concrete filling does not become tight and interferes.

In Korea, interest in seismic performance of buildings is increasing. In particular, the importance is growing as the seismic performance of the building itself is judged through the ductile behavior of the structural member joints. The welded joint shows a brittle fracture pattern, and the energy dissipation capacity, which is an index of seismic performance, is evaluated as low. A joint structure with the required seismic performance by minimizing welding is required.

In the case of steel structures, brackets are generally welded in factories and bolted on site. In the case of the bracket method, the amount of loading is limited during transport, and the manufacturing process is complicated because pillars and welding are performed, and a separate test for quality is required. In order to solve this problem, the welding process efficiency can be maximized during factory production and the end plate joining method is applied for easy loading during transport. However, the end plate joint requires the installation of stiffeners to prevent bending deformation of the plate between the column and the beam. At this time, the height of the stiffener must be secured at a certain height according to the joint design formula, which may protrude above the slab, thereby hindering architectural aesthetics.

The column 10 is a steel pipe having a vertical cross-section of a polygon, preferably a rectangle, and may have a steel material.

Here, the pillar 10 is generally standardized so that a plurality of pillar members 100 are vertically coupled to form one pillar 10 in order to extend the vertical length.

The plurality of pillar members 10 are installed at a pre-designed position and are vertically coupled to form one pillar 10, and a rectangular steel pipe or the like may be used.

The beam 200 is installed to connect the pillar 10 and the adjacent pillar 10 , and is a beam coupled to at least one coupling surface among the side surfaces of the pillar 10 , and may have various configurations.

As an example, the beam 200 may include a pair of flange portions 210 coupled to the upper and lower ends of the web 220 and the web 220 and may have the shape of an H-shaped steel, and may have a steel material. have.

Meanwhile, with respect to the column 10 having the above configuration, the beam 200 according to the present invention is coupled by the column-beam coupling structure.

At this time, the column-beam coupling structure according to the present invention is fixedly coupled to the column 10 and the beam 200 to fix the beam 200 to the column 10, as shown in FIGS. 1 to 2 . It includes one or more coupling assemblies 300 .

The coupling assembly 300 is a configuration that is fixedly coupled to the pillar 10 and the beam 200 to fix the beam 200 to the pillar 10, and various configurations are possible.

For example, the coupling assembly 300 may include a plurality of coupling members 310 sequentially connected in the circumferential direction to surround the pillar 10 .

The plurality of coupling members 310 are sequentially connected in the circumferential direction to surround the pillar 10, and may have various configurations depending on whether the beams are coupled.

For example, the beam 200 may be coupled to at least one of the plurality of coupling members, and the coupling member 310 to which the beam 200 is coupled is a first bolt assembly 901 on the side surface of the pillar 10 . ( 312) may be included.

The pillar coupling part 311 is a configuration coupled to the side surface of the pillar 10 by the first bolt assembly 901 , and various configurations are possible.

For example, the column coupling part 311 may be formed of a plate-shaped member in consideration of being closely coupled to the side surface of the column 10 .

Here, the pillar coupling part 311 and the pillar 10 are coupled by the first bolt assembly 901 , and a coupling hole into which the bolt of the first bolt assembly 901 is inserted is formed.

Here, the first bolt assembly 901 is composed of a bolt and a nut, and various configurations are possible as a configuration for coupling the column coupling part 311 and the column 10 to each other.

Meanwhile, the coupling assembly 300 includes a plurality of coupling members 310 sequentially connected in a circumferential direction so as to surround the pillar 10, and the plurality of coupling members 310 are coupled to each other along the circumferential direction. There is a need.

The part 315 and the second bolt assembly 902 may be fixedly coupled to each other.

That is, since the coupling assembly 300 is installed to surround the pillars, the pillar coupling parts 311 may be connected to each other by additionally including a connection extension part 315 to the pillar coupling part 311 .

Specifically, the coupling member 310 coupled to the beam 200 is coupled to at least one of the top and bottom of the beam 200, and the load of the coupled beam 200 is applied thereto. The beam 200 can be supported by having a clamp structure coupled to the column 10 by being fixedly coupled to the adjacent connection extension 315 by additionally including a connection extension part 315 to 311).

As a specific example, the connection extension part 315 may be configured to be coupled to the adjacent connection extension part 315 by protruding both ends of the column coupling part 311 to the outside of the side of the column 10 . In this case, the connection extension part 315 may be coupled to the adjacent connection extension part 315 by a second bolt assembly 902 or welding.

The flange coupling portion 312 is vertically extended from the column coupling portion 311 and is coupled to the flange portion 210 of the beam 200 by a fifth bolt assembly 905 , and various configurations are possible.

The joint portions 421 and 610 have a configuration formed by being bent inward in connection with the other inner column joint member 420 , and may be coupled to the other inner column joint member 420 by welding or the like.

On the other hand, the inner column joint member 420 may have various connection structures, such as being connected to the adjacent inner column joint member 420 along the circumferential direction, or connected to the opposite inner column joint member 420, of course. .

As a specific embodiment, the inner pillar joint member 420, as shown in FIGS. 6A and 6B, may be formed so that the entire shape of the column is in a rectangular shape by being in contact with the inner circumferential surface of the pillar 10.

Here, an oblique line is formed near a vertex of the rectangular overall shape to have a substantially rectangular shape, and the overall shape may form an octagonal shape. Accordingly, the overall shape may be composed of two members that are bent inwardly in the vicinity of the vertices to form a rectangle and are coupled to each other.

Meanwhile, both the outer column joint member 410 and the inner column joint member 420 having the above structure may be installed, and at this time, as shown in FIG. 6C, the outer column joint member 410 and the inner column joint member ( 420 may be integrally formed by the column joint member connecting portion 431 or may be coupled by welding.

In this case, the column joint member connecting portion 431 is positioned on the coupling surface of the pair of column members 100, and the side cross-section forms an 'H' shape. Since the inside and outside are integrally connected, the coupling of the pair of pillar members 100 can be made stronger.

And a through hole into which the third bolt assembly 903 coupling the outer column joint member 410 and the inner column joint member 420 and the pair of column members 100 can be inserted is formed, the through hole is A plurality may be formed vertically, horizontally and vertically.

On the other hand, the outer column joint member 410 and the inner column joint member 420, in consideration of structural reinforcement to withstand the applied load, over both the column member 100 located on the upper side and the column member 100 located on the lower side installed is preferred.

On the other hand, in the column-beam coupling structure of the beam 200 and the column 10 by the connection part 300, the connection part 300 coupling the beam 200 applies a load to the lower side, and a reinforcement structure for this is added. It is preferable to provide

Accordingly, the column-beam coupling structure according to the present invention is installed on the side of the column 10 as shown in FIG. 1 , and the lower end of the coupling member 310 located on the lower side of the plurality of coupling members 310 . It may further include one or more stopper members 500 for supporting the.

The stopper member 500 is installed on the side of the pillar 10, and supports the lower end of the coupling member 310 located on the lower side of the plurality of coupling members 310, and various configurations are possible.

For example, the stopper member 500 may be configured as a plate member coupled to the sidewall of the pillar 10 to support the lower end of the coupling member 310 .

And it is preferable that the stopper member 500 has a thickness greater than the thickness of the coupling member 310 in consideration of supporting the lower end of the coupling member 310 .

In addition, the stopper member 500 may be fixed to the side wall of the pillar 10 by a sixth bolt assembly 906 .

At this time, an inner reinforcing part 600 , which will be described later, is coupled to the inner surface of the post 10 to which the stopper member 500 is coupled, for reinforcement of the bolt coupling structure, and the stopper member ( 500), the pillar 10 and the internal reinforcement 600 may be fixedly coupled.

On the other hand, the stopper member 500, the pillar 10 and the beam 200, the coupling assembly 300, the outer column joint member 410 and the inner column joint member 420 when the through-holes do not deviate from each other when they are combined. It can play a role in adjusting the position.

On the other hand, when the pillar 10 and the pillar coupling part 311 are coupled by bolts, a relatively large force is concentrated on the portion where the bolts on the inner surface of the pillar 10 are coupled, so structural reinforcement is required.

Accordingly, in the column-beam coupling structure according to the present invention, as shown in FIG. 4 , the column coupling part 311 and the column 10 are coupled by a first bolt assembly 901 , at this time the column 10 It may further include one or more internal reinforcement 600 for reinforcing rigidity by combining with the column 10 and the column coupling portion 311 on the inner surface of the.

The internal reinforcing part 600 may increase the structural stability of the pillar 10 by dispersing the force applied to the portion to which the first bolt assembly 901 is coupled.

And the internal reinforcement 600 is a configuration for reinforcing rigidity by coupling with the pillar 10 and the pillar coupling part 311 on the inner surface of the pillar 10, and may be composed of a plate member such as a plate shape.

In addition, as shown in FIG. 6b , the inner reinforcing part 600, like the inner column joint member 410, forms a rectangular shape by interviewing the inner circumferential surface. It may consist of members.

On the other hand, in the column-beam coupling structure according to the present invention, the through-holes are formed according to the design position so that the column 10, the beam 200, the coupling assembly 300, etc. can be coupled by a bolt assembly to be described later. .

The through-holes may be formed in various places in consideration of the stable coupling of the pillar 10 and the beam 200 .

And the column-beam coupling structure according to the present invention is the first bolt assembly 901 to the sixth bolt assembly 902 described above in the coupling of the column 10, the beam 200, the coupling assembly 300, etc. By having an assembly structure that is combined by the

The first bolt assembly 901 to the sixth bolt assembly 902 is a bolt assembly by a bolt and nut combination, and is a configuration for coupling the column 10, the beam 200, the coupling assembly 300, and the like. Various configurations are possible.

On the other hand, in the column-beam coupling structure according to the present invention, it is difficult to combine the coupling assembly 300 to the column 10 with the closed cross-sectional structure of the column 10 when the bolt and the nut are coupled to the inside of the column 10. have.

Accordingly, in the column-beam coupling structure according to the present invention, a bolt assembly capable of bolting and nut coupling despite the closed cross-sectional structure of the column 10 when the bolt and nut are coupled to the inside of the column 10, a so-called one-way bolt assembly By providing, without using welding, there is an advantage that the beam 200, the column 10, and the assembly 300 can be easily and quickly constructed.

As shown in FIGS. 8 to 13 , the one-way bolt assembly according to the present invention may include a first nut 60 , a coupling bolt 50 , a second nut 80 , and a washer 90 . .

Specifically, the one-way bolt assembly, as shown in Figs. 8 to 13, the base material (M), for example, the insertion portion 62 is inserted into the insertion hole formed in the inner reinforcement portion 600, and the insertion a first nut 60 having an outer diameter greater than the outer diameter of the portion 62 and including a head portion 61 formed in a nut shape, and having a thread formed on an inner circumferential surface; A first screw thread 54 screwed to the first nut 60 is formed at one end, a second screw thread 55 is formed at the other end, and the pin tail 56 to which the rotating mechanism is coupled is a second screw thread ( 55) and the extended coupling bolt 50; a second nut (80) opposite to the first nut (60) and screwed to the second thread (55); It is installed between the column coupling part 311 and the second nut 80 and the coupling bolt 50 may include a washer 90 penetrating the center.

The first nut 60 is, as shown in FIGS. 8, 10, and 13, the base material M, for example, the insertion part 62 inserted into the insertion hole formed in the internal reinforcement part 600 and , has an outer diameter greater than the outer diameter of the insertion portion 62, and includes a head portion 61 formed in the form of a nut, and various configurations are possible as a configuration in which a thread is formed on the inner circumferential surface.

In particular, the first nut 60 is a base material M, for example, a through hole formed in the column 10 or a through hole formed in the inner reinforcing member 420 described above, or a through hole formed in the inner reinforcing part 600 . Various configurations are possible as a nut that is inserted into the ball and screwed with a coupling bolt 50 to be described later.

In particular, the insertion part 62 of the first nut 60 has a smaller diameter than the head part 61 so that it can be inserted into the base material M, and is generally press-fitted into the through hole formed in the base material M. As a result, it is preferable to have an outer diameter substantially equal to the inner diameter of the through hole.

In addition, a plurality of protrusions may be formed on the outer circumferential surface of the insertion portion 62 of the first nut 60 to prevent rotation while being press-fitted into the through hole formed in the base material M.

The head part 61 may have a nut shape, such as a hexagonal nut or an octagonal nut.

Meanwhile, the first nut 60 has a screw thread formed on its inner circumferential surface so as to be screwed to a first screw thread 54 to be described later, and is preferably formed only in the head portion 61 .

At this time, the first screw thread portion 54 is preferably formed to correspond only to the inner circumferential surface of the head portion 61 of the first nut 60 when screwing with the first nut 60 .

In summary, the second nut 80 has the same shape as a normal nut and is disposed on the opposite side of the first nut 60 with the base material M, which is an object through which the coupling bolt 50 penetrates, disposed on the coupling bolt ( 50) is coupled in a penetrating form.

The coupling bolt 50 has a pin tail having a first screw thread 54 screwed to the first nut 60 is formed at one end, a second screw thread 55 is formed at the other end, and a rotating mechanism is coupled thereto. As a configuration in which (56) is formed extending from the second screw thread (55), various configurations are possible.

Here, the direction of the first screw thread portion 54 and the second screw thread portion 55 is preferably opposite to each other.

In addition, the coupling bolt 50 has a predetermined length in consideration of the total thickness of the members to be coupled, and a first screw thread 54 and a second screw thread 55 may be formed at one end and the other end.

That is, the coupling bolt 50, as shown in FIG. 9, is formed to be long and is coupled to the first nut 60 in the form of penetrating the body 53, and the longitudinal direction of the body 53 Accordingly, the first screw thread part 54 and the second screw thread part 55, which are threads formed on the outer surface of the body part 53 and spaced apart from each other, and the body part 53 are formed so as to extend to the end of the body. A mechanism for rotating the portion 53 may include a pin tail 56 coupled thereto.

In addition, the first screw thread portion 54 and the second screw thread portion 55 may be formed to have different diameters.

The pin tail 56 is formed in a form extending to the end of the body 53 to be coupled to a mechanism for rotating the body 53, and is typically extended to rotate the coupling bolt 50. It is a portion formed to be able to grip the coupling bolt 50 for the purpose.

The washer (90) includes a second nut (80) opposite to the first nut (60) and screwed to the second thread (55); It is installed between the column coupling part 311 and the second nut 80 and the coupling bolt 50 penetrates the center, and various configurations are possible.

The washer 90 is disposed between the base material M and the second nut 80 and is coupled in such a way that the coupling bolt 50 penetrates the center.

And the washer 90 is also in the same form as the normal washer (90).

In addition, the washer 90 serves to make the coupling between the coupling bolt 50 and the base material M more robust by maximally suppressing the relative variation between the base material M and the second nut 80 .

Meanwhile, as shown in FIG. 8 , the first screw thread portion 54 and the second screw thread portion 55 formed on the coupling bolt 50 are formed in opposite directions to each other.

In this case, when the bolt assembly according to the present invention is coupled and assembled to the base material M, even if the coupling bolt 50 is rotated in only one direction, the first nut 60 and the second installed with the base material M interposed therebetween. Nuts 80, respectively, receive a force in a direction approaching the base material M, where the first nut 60 is press-fitted to the base material M and fixed, so the pin tail 56 is finally tightly tightened. ) is gripped with a tool and rotated, the second nut 80 is finely tightened in the direction of digging into the base material M, and the second nut 80, the washer 90, and the base material M are compressed in this order.

Therefore, in the present invention, even if the center of the coupling bolt 50 is not rotated, if the pin tail 56 provided on one side of the coupling bolt 50 is rotated, the first nut 60 and the second nut 80 are connected to each other at the same time. direction, so that two nuts can be fastened simultaneously.

Therefore, the bolt can be combined by rotating the bolt in one direction, so it can be usefully used in a steel pipe structure of a closed section.

For example, as shown in Fig. 1a, when combining the column coupling part 311 and the column 10, the fastening operation is performed only outside the column 10, so it is not possible to use a general conventional bolt joint, so only welding It was possible.

However, in the bolt assembly of the present invention, since it is possible to combine the column coupling part 311 and the column 10 only by fastening work from the outside of the column 10, there is an advantage of simplicity and speed of bolting.

That is, by using the one-way bolt assembly for the first bolt assembly 901 to the sixth bolt assembly 906, the advantages of simple and rapid construction of the column-beam coupling structure according to the present invention can be maximized.

On the other hand, in the press-fit nut-bolt assembly according to the present invention, as shown in FIGS. 11 and 12 , the first screw thread portion 54 and the second screw thread portion 55 may be manufactured to have different diameters.

In particular, a step 53a having a reduced diameter is formed between both ends of the body portion 53, and a thread having a larger outer diameter among the first screw thread portion 54 and the second screw thread portion 55 is the step difference. It may be formed in the body portion 53 of the larger diameter around (53c).

In this case, there are two effects. First, when inserting the coupling bolt 50 in a state in which the two base materials (M) are joined, the end is caught between the two base materials (M) and insertion is not easy, inserting the smaller diameter makes it easier to insert possible effect.

The second is the effect that the coupling bolt 50 can have the same performance as the case with the bolt head despite the absence of the bolt head.

12A and 12B, when both sides of the body part are divided around the step 53c, the body part on the first screw thread part 54 side is called the first body part 53a, and the The body portion of the two-thread side 55 will be referred to as a second body portion 53b.

At this time, when inserting the coupling bolt 50 into the overlapping base material (M), even if the hole formed in the overlapping base material (M) is slightly shifted, the coupling bolt 50 collides with the interface of the base material (M) during the insertion process, and the insertion is not easily made. Problems that are not possible may arise. At this time, as shown in FIGS. 12A and 12B , when the outer diameter of the side to be inserted first among both ends of the coupling bolt 50 is small, that is, based on the upper part of FIG. 12B , from the second screw thread part 55 to the base material M ), it can be easily inserted.

In addition, apart from the ease of insertion, a step 53c is formed at the boundary between the first body part 53a and the second body part 53b, and the step 53c acts similar to the bolt head, so that the coupling bolt 50 ) is installed, and then the step 53c is no longer allowed to be inserted in the direction in which it is inserted, so that loosening due to variability in both directions can be prevented.

On the other hand, as shown in FIG. 13 , the hollow inner surface formed in the first nut 60 has a screw thread formed in a portion corresponding to the inner side of the head portion, and a non-threaded portion is formed in a portion corresponding to the insertion portion 62 . It can be made to have an inner side. In the conventional press-fit nut, a screw thread is continuously formed in the hollow of the insertion part as well as the head part.

In this case, the residual stress of the base material (M) pushed by the insertion unit to the periphery in the process of press-fitting the insertion unit into the base material (M) is directed toward the center of the insertion unit again, thereby causing deformation of the screw thread formed in the hollow of the insertion unit.

Therefore, as shown in FIG. 13 , the inner surface of the hollow 70 of the insertion part 2 is formed with a screw thread removed, thereby preventing the bolt from being inserted due to the deformation of the screw thread.

On the other hand, by using the construction method shown in FIG. 15 in order to shorten the construction period and improve the convenience of construction, it is possible to construct a column-beam building conveniently and quickly.

Hereinafter, in the construction method according to the present invention, a pair of pillars (10) adjacent to each other are installed at preset intervals in the horizontal and vertical directions and are formed by stacking a plurality of pillar members 100 up and down. 10) discloses a construction method of a building consisting of a plurality of beams 200 that horizontally connect them.

In particular, the construction method according to the present invention is suitable for installation at preset intervals in the horizontal and vertical directions, that is, the construction of a building having a lattice structure in which a plurality of flat rectangles are formed.

Specifically, the construction method of a building according to the present invention comprises: a pillar construction step (S10) of installing four pillars 10 installed in correspondence with the vertex positions of a flat rectangle at a construction site; It may include a column coupling step (S20) of combining the four beams 200 to be coupled to the planar rectangular column and coupling one pre-fabricated module 800 to the four columns 10 in advance.

The pillar construction step (S10) is a step of installing four pillars 10 installed corresponding to the vertex positions of the flat rectangle at the construction site, and may be appropriately performed according to the design structure of the building.

For example, as shown in FIG. 14, the building may have a lattice structure in which a plurality of flat rectangles are installed at preset intervals in the horizontal and vertical directions, in this case, the pillar construction step (S10) can be installed at a position that intersects the plane rectangle and the vertex.

That is, in the column coupling step (S20), as shown in FIGS. 14 and 15A , the column member 100 of the same height may be installed corresponding to each intersection in the grid structure.

The column coupling step (S20) is, as shown in FIGS. 15A to 15C and 17A to 17D , one prefabricated module manufactured in advance by combining four beams 200 to be coupled to a flat rectangular column. As a step of coupling the 800 to the four pillars 10, it may be performed by various methods.

Here, the pre-production module 800 has the advantage of significantly reducing the construction time by prefabricating it in advance at a place other than the construction site, such as a factory, and then assembling it with the pillar 10 at the construction site.

On the other hand, the pre-production module 800 is a configuration that is pre-fabricated at a place other than the construction site, such as a factory, and then assembled with the pillar 10 at the construction site. Four beams 200 to be coupled to the flat rectangular pillar are combined The overall shape may be a rectangle as a basic configuration.

At this time, each of the four beams 200 forming a planar rectangular shape must maintain a coupled state with the adjacent beam 200, and the pre-production module 800 provides a coupling structure between adjacent beams 200. should be provided

For example, the prefabrication module 800 may include at least a portion of the column-beam coupling structure in which the four beams 200 forming a rectangular shape are described above with reference to FIGS. 1 to 7B .

More specifically, the pre-production module 800 may include at least a portion of the coupling assembly 300 described above, as shown in FIGS. 18A and 18B .

That is, the beam 200 may be coupled to the column 10 by the above-described column-beam coupling structure.

And the pre-production module 800 is located at a position corresponding to the vertices of the four beams 200 and the flat rectangle to connect the two adjacent beams 200 and also to attach the beam 200 to the column 10 . It may include a column-beam coupling structure for coupling.

In addition, the pre-production module 800, as shown in FIGS. 16A to 16D, the column member 100 is coupled to a position corresponding to the vertex of a planar rectangle in at least one of the upper and lower portions of the column-beam coupling structure. can be

As shown in FIG. 14, when the building has a lattice structure in which a plurality of flat rectangles are formed, the column combining step (S20) is installed such that the pre-fabricated module 800 intersects the adjacent planar rectangle and the vertex. can be performed.

More specifically, the pre-fabrication module 800 may be installed in a position where sides are not shared and vertices are shared, such as ①, ③, ⑤, ⑦, and ⑨ in the grid structure of FIG. 14 .

On the other hand, the building is a building of a steel structure, and the pillar member 100 is divided into one layer to form a single pillar by dividing the pillar member 100 into a single layer, that is, a plurality of pillar members 100 are stacked and installed.

The beam 200 may be coupled to the connecting portion of the column member 100 coupled up and down, and in this case, may be coupled to the column 10 by the coupling assembly 300 described above.
