Description

Concrete column using prefabricated rebar module

The present invention is to be applied to a vertical member of a reinforced concrete structure, and by connecting a vertical steel material disposed at the member edge by a horizontal strip steel plate, but passing through a through hole formed in the vertical strip steel plate and combining a plurality of large-diameter reinforcement, constructability is improved It is about a concrete column using a pre-assembled large-diameter reinforcing bar module that is excellent, can shorten the construction period, and has excellent structural performance.

In a skyscraper, the stress acting on the vertical members of the structure is quite large due to the building's own weight. Therefore, a gravity resistance system to support vertical load is important, and a lateral force resistance system to support it is also required because the influence of lateral loads such as earthquake and wind loads is large.

In order to resist gravity and lateral loads, concrete walls with excellent in-plane resistance are mainly used as the core of buildings.

In addition, in high-rise buildings, extra-large mega-pillars with a cross-sectional size of about 3m are often used.

In these large vertical members, a large amount of reinforcing bars are placed in the members to resist high gravitational and lateral loads.

In addition, when it is necessary to increase the rebar ratio, it is advantageous to use large-diameter reinforcing bars of D35 or more rather than using a large amount of small-diameter rebars due to limitations in rebar diameter and spacing, and it is advantageous in terms of constructability by reducing the number of rebars.

However, the D35 rebar has a unit weight of 7.51 kg/m, and the D51 rebar used in Lotte Tower has a unit weight of 15.9 kg/m. Accordingly, many workers must be put in to move, lift, and install rebar. In addition, there is a risk of safety accidents because heavy objects are installed by working at height.

On the other hand, in order to maximize the bending strength of such a large member, the steel material should be concentrated in the corner portion of the member. However, in this case, it is difficult to join the reinforcing bars, and the tight spacing of the reinforcing bars makes it difficult to place concrete tightly.

In addition, for extra-large vertical members, the operator must perform the reinforcement work within the member, and there are cases where it is difficult for the operator to come out of the member after the work is completed due to the interference of the main reinforcing bars and the band reinforcing bars.

In addition, the bending strength of the structure can be increased by intensively arranging vertical steel materials at the corners of the member, and the structural performance can be improved with a simple configuration because the horizontal strip steel plate resists the member shear force.

In addition, it is possible to easily form a concrete wall or column by arranging pre-assembled large-diameter rebar modules at appropriate intervals, and in this case, workers can pass between neighboring pre-assembled large-diameter rebar modules.

1 to 3, and the like, the pre-assembled large-diameter reinforcing bar module is a vertical steel material 31 disposed at each corner of the pre-assembled large-diameter reinforcing bar module (3); a horizontal strip steel plate 32 provided with a plurality of vertically spaced apart to interconnect the vertical steel material 31 in the transverse direction and having a plurality of through-holes 321 and 322 formed thereon; and a large-diameter reinforcing bar 33 through-coupled to the through-holes 321 and 322 of the horizontal strip steel plate 32 spaced apart from one another in the vertical direction; It is characterized in that it is composed of

An object of the present invention is to provide a concrete column using a pre-assembled large-diameter reinforcing bar module that is applicable to various types of vertical concrete members and has excellent workability, shortening of construction period, and excellent structural performance.

The pre-assembled large-diameter reinforcing bar module 3 is pre-assembled to form a reinforced concrete structure, and includes a vertical steel material 31 , a horizontal steel strip 32 and a large-diameter reinforcing bar 33 .

The vertical steel material 31 is disposed at each corner of the pre-assembled large-diameter reinforcing bar module (3).

When the cross-section of the pre-assembled large-diameter reinforcing bar module 3 is a quadrilateral, four vertical steel materials 31 are disposed at each corner.

As in FIG. 7 to be described later, when the pre-assembled large-diameter reinforcing bar module 3 is disposed at the edge of the wall, the pre-assembled large-diameter reinforcing bar module 3 may be formed in a L-shape. In this case, five vertical steel materials 31 may be disposed at each corner.

Since the vertical steel material 31 is concentrated at the member edge, it is possible to maximize the bending strength of the member.

The vertical steel material 31 not only fixes the position of the horizontal strip steel plate 32, but also serves as a main pillar in the concrete.

The vertical steel material 31 may be composed of a steel pipe, a section steel, a steel strip, a steel bar, or the like.

The horizontal strip steel plate 32 interconnects the adjacent vertical steel materials 31 in the transverse direction, and is provided with a plurality of vertically spaced apart from each other.

A plurality of through-holes 321 and 322 are formed in the horizontal strip steel plate 32 for coupling of a large-diameter reinforcing bar 33 to be described later.

The horizontal strip steel plate 32 may be configured in a rectangular shape.

The horizontal strip steel plate 32 may be coupled to the vertical steel material 31 by welding, bolting, or the like.

The large-diameter reinforcing bar 33 is coupled through the through-holes 321 and 322 of the horizontal strip steel plate 32 that are vertically spaced apart.

The large-diameter reinforcing bar 33 is inserted into the through-holes 321 and 322 formed in the horizontal strip steel plate 32, and the position is fixed.

As described above, the position of the plurality of large-diameter reinforcing bars 33 is fixed by the horizontal strip steel plate 32, and the horizontal strip steel plate 32 is a vertical steel material 31 disposed on the outside of the pre-assembled large-diameter reinforcing bar module 3 position is fixed by Therefore, it is possible to form a pre-assembled large-diameter reinforcing bar module 3 in which a plurality of large-diameter reinforcing bars 33 are integrated.

Therefore, a plurality of large-diameter reinforcing bars 33 can be installed at the same time, and the rebar spacing can be accurately maintained. In addition, since it is possible to omit the reinforcing bar binding work during reinforcing bars, there are effects such as improvement of workability, shortening of construction period, precise construction, and prevention of safety accidents in the workplace.

The horizontal strip steel plate 32 not only serves as a guide plate for fixing the position of the large-diameter reinforcing bar 33, but also connects the vertical steel material 31 serving as a main bar in the transverse direction, and transverse reinforcement to resist the shear force of the concrete member acts as an absence.

1, 2, etc., the vertical steel material 31 is a steel plate, the end of the horizontal strip steel plate 32 may be fixed to the inner side of the steel plate (32).

In accordance with the shape of the pre-assembled large-diameter reinforcing bar module 3, the A-shaped steel may be used as the vertical steel 31 so that the steel is disposed at the corner.

Accordingly, the amount of steel is concentrated at the edge of the pre-assembled large-diameter reinforcing bar module 3 to increase the flexural rigidity of the member.

In addition, since the inner side of the A-shaped steel is open, the horizontal strip steel plate 32 can be easily coupled to the inner side of the A-shaped steel.

Figure 4 is a perspective view showing the coupling relationship of the upper and lower pre-assembled large-diameter reinforcing bar modules.

As shown in FIGS. 3 and 4 , a coupler 34 may be coupled to the upper end of the large-diameter reinforcing bar 33 .

The coupler 34 may be coupled to the upper end of the large-diameter reinforcing bar 33 in order to connect the pre-assembled large-diameter reinforcing bar modules 3 and 3' adjacent up and down.

The position of the large-diameter reinforcing bar 33 is precisely fixed by the horizontal strip steel plate 32 . Therefore, when installing the pre-assembled large-diameter reinforcing bar module 3 to be newly installed on the pre-assembled large-diameter reinforcing bar module 3 installed at the bottom, the positions of the upper and lower large-diameter reinforcing bars 33 and 33' are the same, so that the coupler 34 is connected. This is easy.

The coupler 34 may be fastened to the large-diameter reinforcing bar 33 in the field, but for convenience in construction, it is preferable to fasten it in advance when assembling the pre-assembled large-diameter reinforcing bar module 3 .

2 to 4, the lower portion of the coupler 34 of the large-diameter reinforcing bar 33 may be provided with an upper fixing ring 331 mounted on the upper surface of the uppermost horizontal band steel plate 32.

The upper fixing ring 331 may be coupled to the upper portion of the large-diameter reinforcing bar 33 in order to fix the large-diameter reinforcing bar 33 to the horizontal strip steel plate 32 without separately welding or the like.

The upper fixing ring 331 is mounted on the upper surface of the horizontal strip steel plate 32 by the weight of the large-diameter reinforcing bar 33 and the position is fixed.

In particular, in the case of using the screw fastening coupler 34, the coupler 34 must be rotated to connect with the upper large-diameter reinforcing bar 33'. At this time, the large-diameter reinforcing bar 33 has a large weight, and it is difficult to rotate the coupler 34 in a state in which the coupler 34 is mounted directly on the horizontal band steel plate 32 and is in close contact. In this case, when the upper fixing ring 331 supports the large-diameter reinforcing bar 33 in the lower portion of the coupler 34, the coupler 34 can be rotated more freely to be coupled to the large-diameter reinforcing bar 33'.

As described above, the upper fixing ring 331 is mounted on the upper surface of the uppermost horizontal strip steel plate 32 to prevent the large-diameter reinforcement 33 from falling out when the pre-assembled large-diameter reinforcement module 3 is erected, and the coupler 34 Make sure that no load is applied to the

The upper fixing ring 331 may be configured by welding a washer plate. Alternatively, the upper fixing ring 331 may be configured by screwing a nut to the thread formed on the upper outer peripheral surface of the large-diameter reinforcing bar 33 .

2, 3, the lower end of the large-diameter reinforcing bar 33 may be provided with a lower fixing ring 332 in close contact with the lower surface of the lowermost horizontal strip steel plate 32.

In the state in which the pre-assembled large-diameter reinforcing bar module 3 is erected, even if the upper part of the large-diameter reinforcing bar 33 is fixed only with the upper fixing ring 331, the position of the large-diameter reinforcing bar 33 can be fixed by the weight of the large-diameter reinforcing bar 33. can

However, when transporting or loading the pre-assembled large-diameter reinforcing bar module 3, the member must be laid down to manage it, so the large-diameter reinforcing bar 33 may fall into the upper part of the pre-assembled large-diameter reinforcing bar module 3 . Therefore, the lower fixing ring 332 is also closely fixed to the horizontal strip steel plate 32 under the large-diameter reinforcing bar 33 to prevent the large-diameter reinforcing bar 33 from being separated during transport or installation of the pre-assembled large-diameter reinforcing bar module 3 . can be configured to do so.

That is, the upper portion of the large-diameter reinforcing bar 33 is provided with an upper fixing ring 331 to be in close contact with the uppermost horizontal belt steel plate 32, and the lower portion is provided with a lower fixing ring 332 to the lowermost horizontal belt steel plate 32. Since it is in close contact, it is possible to fix the large-diameter reinforcing bar 33 without separate welding.

Accordingly, when manufacturing the pre-assembled large-diameter reinforcing bar module 3, fixing operations such as welding can be minimized, and the use of rebar for welding is unnecessary, thereby reducing manufacturing time and unit cost.

As shown in FIG. 2 , the diameter of the through hole 322 of the horizontal strip steel plate 32 disposed below may be larger than the through hole 321 of the horizontal strip steel plate 32 disposed on the uppermost portion.

When the upper and lower large-diameter reinforcing bars 33 and 33' are joined by the coupler 34, the positions of the upper and lower large-diameter reinforcing bars 33 and 33' must exactly match.

Therefore, in order to fine-tune and match the positions of the upper and lower large-diameter reinforcing bars 33, 33', the diameter of the through-holes 321 and 322 of the horizontal strip steel plate 32 is preferably configured to be larger than the diameter of the large-diameter reinforcing bars 33 Do.

However, in this case, when the pre-assembled large-diameter reinforcing bar module 3 is transported or installed, the large-diameter reinforcing bar 33 moves due to the clearance between the large-diameter rebar 33 and the through-holes 321 and 322, and shock and noise may occur. Therefore, the size of the through hole 321 of the uppermost horizontal strip steel plate 32 is formed to have a size corresponding to the diameter of the large-diameter reinforcing bar 33 to minimize the flow of the large-diameter reinforcing bar 33 .

On the other hand, when the upper and lower fixing rings 331 and 332 are composed of nuts, when transporting or manufacturing the pre-assembled large-diameter reinforcing bar module 3, the upper and lower fixing rings 331 and 332 are tightened to adhere to the horizontal strip steel plate 32. It can be fixed so that the large-diameter reinforcing bar 33 does not move. And when fixing the upper and lower large-diameter reinforcing bars 33, 33' with the coupler 34, loosen the lower fixing ring 332 of the upper pre-assembled large-diameter reinforcing bar module 3' to freely release the lower position of the large-diameter reinforcing bars 33' Joint work can be performed in a movable state.
