Description

TECHNICAL FIELD [0001] The present invention relates to a composite modular structure and a method of constructing the composite modular structure.

The present invention relates to a composite modular structure using engineering wood and a construction method thereof. More particularly, the present invention relates to a composite modular structure using an engineering wood which is eco-friendly, and which is advantageous in fire resistance and lateral resistance, when a module unit is laminated to a middle-floor modular building.

1A and 1B are perspective views of a module unit 1 for a conventional modular building.

That is, the modular building module unit 1 comprises the panel part 30 and the joint part 40,

The panel unit 30 is composed of a horizontal panel 31 constituting the bottom and ceiling of the module unit 1 and a vertical panel 32 constituting a wall.

Generally, in the case of the load-bearing type structure, the vertical panel 32 may be composed of a stud 33, which is a vertical member, and a track 35, which is a horizontal member disposed above and below the stud 33. In this case, the stud 33 refers to a vertical aggregate constituting a wall, and the track 35 refers to a horizontal member which fixes the stud 33 at the upper and lower portions of the wall.

The horizontal panel 31 is composed of a bottom panel 31a and a ceiling panel 31b and the bottom panel 31a and the ceiling panel 31b may be formed in the same shape and method.

The horizontal panel 31 includes a frame 31c and a plurality of joists 31d attached to the inside of the frame 31c as shown in FIG. And a joining auxiliary member 31e interposed in a corner portion of the frame 31c and coupled to the joining portion 40. [

The joining auxiliary member 15 can be joined to the edge where the end of the 'C' shaped steel forming the frame 16 is engaged, and the two rectangular surface members are connected in a ' .

The joining auxiliary member 31e may be formed with a bolt fastening hole 31f so that joining with the joining part 40 is facilitated.

The joining portion 40 is interposed between corners of the panel portion 30 so that at least one surface of the joining portion 40 is in surface contact with the panel portion 30 to integrally connect the horizontal panel 31 and the vertical panel 32, So that it also serves as a supporting member for supporting the module unit 1 from the factory to the site.

1C is an illustration of a module unit using conventional wood.

That is, the edges of the wooden building frame 10 having the spaced studs 11, the top plate 12 and the bottom plate 13 are described. The bottom plate 13 is located on the on-ground slab 14 and the nogging 15 is held in the stud 11 in a suitable spacing relationship. The frame is designed so that the bracing panels 16 according to the present invention are provided with two sets of end studs in each of the illustrated directions, in order to prevent the frames from moving due to wind during manufacture, As shown in FIG.

The bracing panels 16 include an enlarged panel of a dimension that can be located between adjacent vertical studs 11 and between the upper and lower plates 12 and 13 and each panel has opposite ends 17, , Opposite sides (19, 20), and a middle portion (21) between the sides, the middle portion comprising a diamond-shaped reinforcing section (22) arranged transversely from the plane of the panel.

Furthermore, the metal straps 23, 24 extend around the panel to further reinforce the edges that tie the two panels together. Each panel 16 has a box-like structure with sides and flanges (to be described) and is attached to the upper and lower plates using bolts and to the stud 11 using a nail or other fastening device do.

As a result, when the panel unit of the modular building module unit 1 is used as wood, which is an environmentally friendly material, the stud 11 is divided into nogging 15, And the metal straps 23 and 24 are reinforced. It is difficult to secure the material properties of the wood and brittle fracture is likely to occur, and in particular, the performance of the joint between the module unit and the module unit is deteriorated It can be said that it can only be done.

FIG. 1D shows a unit unit 50 made of another conventional wood.

The unit unit 50 includes a column 51 and a beam 52 and an inner joining member 53 and an outer joining member 54 that connect the column 51 and the beam 52 to the unit unit 10, As shown in FIG.

The inner joining member 53 is provided on the inner side of the corner where the column 51 and the beam 52 meet and the outer joining member 54 is provided on the corner where the column 51 and the beam 52 meet, As shown in FIG.

Since the inner joining member 53 and the outer joining member 54 are generally manufactured using iron or steel, the lowering of the coupling force between the column 51 and the beam 52 can be prevented and the resistance to vertical and horizontal can be increased .

The inner joining member 53 and the outer joining member 54 may be made of a similar material other than iron and steel. For example, the thixotropic agents such as alloys and titanium exhibit a strength similar to that of the steel material, so that the lowering of the coupling force between the column 51 and the beam 52 can be prevented and the resistance against vertical and horizontal can be increased.

Therefore, when the unit unit 50 is made of wood, reinforcing steel is required for connection between the column and the beam. If such a reinforcing steel is used, it is difficult to overcome the weakness at the connection site because the manufacturing cost and manufacturing complexity are complicated. When a module unit for a modular building is stratified into a secondary structure, a structural restriction requirement is generated, so that there is usually a limit to be applied to four or less layers.

Furthermore, since wood is vulnerable to fire, there is a problem that it is difficult to obtain structural performance and fire resistance when wood is used in a module unit.

Accordingly, the present invention can be applied to a modular high-modulus building (continuously installed at a height of about 15 to 15 stories) as a modular unit using a composite modular structure using engineering wood and lightweight (bubble) concrete, The present invention provides a composite modular structure using engineering wood that can be sufficiently secured while being easily manufactured, and a technical problem to be solved.

In order to achieve the above object,

First, the module unit composing the modular building is made of a composite modular in the form of a box body combined with studs and tracks made of engineering wood and lightweight foamed concrete. Lightweight foam concrete is formed between the studs installed on the track surface, And a lightweight concrete is formed between adjacent studs so as to serve as corners for the lateral force reinforcement and middle vertical columns at the middle portion between the vertical panels and the middle portion of the vertical panel.

The engineered lumber is formed by laminating a plurality of laminated timbers so as to be used as a structural material of a building. The engineered lumber is environmentally friendly and suitable for use as a structural member.

In addition, the lightweight foamed concrete is intended to reduce the weight of the vertical panel of the composite moduler. In order to compensate the insufficient rigidity of the stud and the track made of the engineering wood, the lateral force of the vertical panel is increased, .

In addition, when the cross section of the vertical panel is enlarged, a lightweight concrete is laid between the adjacent studs so as to further supplement the lateral resistance, and the vertical column is formed at the corner of the composite module, As shown in FIG.

The composite modular according to the present invention is made up of a stud as a wood for engineering and a track as a horizontal member disposed above and below the stud. In particular, lightweight foamed concrete is placed between the studs, And a vertical column portion and a corner portion in which a lightweight concrete is formed between adjacent studs in order to secure the structural rigidity of the composite vertical panel.

To this end,

According to the present invention,

[Vertical panel of composite modular 100 using engineering wood (A11)]

FIG. 2A is a perspective view of a vertical panel of the composite modular 100 using the engineering wood according to the present invention, FIG. 2B is a perspective view of the middle vertical column portion and the corner vertical column portion formed on the vertical panel of the composite modular 100, It is a perspective view.

The modular building (A) according to the present invention is a building constructed by stacking a plurality of module units (A1) in upper, lower, left, and right directions as shown in FIG. 4C.

The module unit (A1) of the present invention is manufactured using the composite module (100) using engineering wood.

As shown in FIGS. 2A and 4B, the composite modular 100 using the engineering wood according to the present invention includes a horizontal panel A12 constituting a floor and a ceiling, and a vertical panel A11 constituting a wall .

In this case, the horizontal panel A11 may be installed on the upper and lower surfaces of the vertical panel A11 as shown in FIG. 4B, and the vertical panel A11 will be described as follows.

Accordingly, it is understood that the vertical panel A11 is connected to the four sides of the vertical panel A11 in the direction of the short side and the long side direction, respectively, to manufacture the composite modular 100 using the engineering wood in the form of a box with a rectangular cross section.

As shown in FIGS. 2A and 2B, the vertical panel A11 of the composite modular 100 using the engineering wood is formed of a plurality of projections 110, a plurality of studs 110, a lightweight foamed concrete 130, a lightweight concrete 140, And includes a vertical column portion 150 and a corner vertical column portion 160.

First, the track 110 and the stud 120 are formed by laminating a plurality of laminated timbers so as to be used as a structural material of a building, and use engineering wood suitable for use as a structural member.

These engineering timbers are easy to process in various forms and are advantageous in that they are economical, environmentally friendly, and superior in structural performance to natural timber compared to expensive natural timbers.

The track 110 is a horizontal member extending horizontally at the lower and upper parts of the vertical panel A11. The studs 120 are spaced apart from each other between the upper track and the lower track. And a lightweight (bubble) concrete to be described later may be formed in a cross-sectional structure in which concave grooves can be integrally formed.

The studs 120 are vertically spaced apart from each other between the upper and lower tracks 110 and are also constructed using engineering wood.

Accordingly, since the track 110 and the stud 120 are made of wood, the track and the stud can be assembled and manufactured quickly and easily by using a screw or the like.

Although the basic skeleton of the vertical panel is provided by the track 110 and the stud 120, the lightweight foamed concrete 130 is integrally formed between the studs 120 to more effectively correspond to the lateral force.

The lightweight foamed concrete 130 is mixed with cement, silica sand, fly ash, slag, quick lime, gypsum, fluidizing agent, stabilizer, etc. at a predetermined ratio and then mixed with a foaming agent to generate bubbles. By weight may be used.

The lightweight foamed concrete 130 is obtained by laying the track 110 and the stud 120 on the bottom plate and then placing the lightweight foamed concrete 130 between the upper surface of the track and the inner surface of the stud, .

The vertical panel A11 of the composite modular 100 using the engineering wood as described above shows that the lightweight foamed concrete 130, the track 110 and the stud 120 are integrally formed.

In this case, when the vertical panel is used for a medium-rise modular building (continuous construction at a height of about 15 to 15 stories), it may not be sufficient to secure a sufficient structural performance for a lateral force. In the corner portion of the vertical panel, The panels must be connected together.

As shown in FIG. 2B, in order to secure a sufficient structural performance against a lateral force, an intermediate vertical column 150 is further formed in the middle of the vertical panel, and a corner vertical column 160 is formed in the corner, So that they can be integrally connected at the corner portions.

For example, the middle vertical column part 150 may be formed by attaching the intermediate stud 120a to the track 110 and the stud 120 in the same manner as the above-described stud 120 is disposed adjacent to the middle of the vertical column part A11 And the lightweight concrete 140 is integrally installed between the two intermediate studs 120a.

Next, the corner vertical posts 160 may be connected in a state in which the edge portions of the vertical panel A11 are disposed at right angles to each other so that the corner studs 120b contact with each other at right angles. The lightweight concrete 140 is integrally formed between the adjacent edge studs 120c and the corner studs 120b so that both adjacent edge studs 120c are located adjacent to the corner studs 120b, .

The lightweight concrete 140 may be a mixture of cement, lightweight aggregate, and the like at a predetermined ratio. The lightweight concrete 140 may be used for structural rigidity at the vertical column and corner portions. Therefore, the lightweight concrete 140 may be separated from the lightweight foamed concrete 130 do.
