콘크리트 슬래브를 경량화함과 동시에 강도를 높이기 위하여 강선의 긴장재를 매립하여 배치하게 되는데, 매립시에 긴장재가 유동하지 않도록 이를 고정하기 위한 고정장치가 구비되어야 한다.In order to reduce the weight of the concrete slab and at the same time increase the strength, the tension member of the steel wire is buried and arranged, and a fixing device for fixing the tension member should be provided so that the tension member does not flow during the burial.

이를 위해서 등록특허 제10-1175484호에서는 '부력방지용 중공모듈과 바 체어에 의한 긴장재 배치를 이용한 장스팬 포스트텐션 중공슬래브 및 그 시공방법'을 제안하였는데, 그 구조로서 도1 부터 도3에 나타난 바와 같이, 콘크리트 내에 경량재(11)와, 부력방지 횡철근(12)과, 고정용 종철근(13)과, 바 체어(14)를 포함하여 구성되는 중공모듈(1)을 포함하고 있으며; To this end, Registration Patent No. 10-1175484 proposed'long span post tension hollow slab and its construction method using a tension member arrangement using a hollow module for preventing buoyancy and a bar chair', and the structure is as shown in Figs. Likewise, it includes a hollow module 1 comprising a lightweight material 11, a buoyancy-preventing transverse reinforcing bar 12, a fixed longitudinal reinforcing bar 13, and a bar chair 14 in the concrete;

상기 중공모듈(1)에서, 상기 경량재(11)는, 종방향으로 열을 이루고 횡방향으로는 열이 복수개 병렬된 형태로 구비되어 있고; 상기 부력방지 횡철근(12)은, 볼록부(120)와 오목부(121)가 번갈아가며 지그재그로 형성되도록 절곡된 형상을 가지고 있어, 상기 중공모듈(1)에서 횡방향으로 이웃하게 놓인 복수개의 경량재(11)의 상부를 각각의 볼록부(120)가 감싸도록 횡방향으로 배치되어 있고; 상기 고정용 종철근(13)은, 상기 부력방지 횡철근(12)이 종방향으로 나란하게 간격을 두고 복수개로 배치된 상태에서, 종방향으로 복수개의 부력방지 횡철근(12)에 걸쳐져서 배치되어 상기 부력방지 횡철근(12)과 결합되어 있고; 상기 바 체어(14)는, 상기 부력방지 횡철근(12)의 오목부(121)에 조립 결합되어 종방향 긴장재(2)를 지지하되, 직립되는 막대부재로 이루어져 하단이 부력방지 횡철근(12)의 오목부(121)에 조립 결합되는 수직부재(141) 및 막대부재로 이루어져 상기 수직부재(141)의 상단에서 횡방향으로 배치되어 결합되어 있고 횡방향의 일단 또는 양단이 부력방지 횡철근(12)과 조립 결합되는 수평부재(142)를 포함하여 구성되어 있으며; In the hollow module (1), the lightweight material (11) is provided in a form in which rows are formed in a longitudinal direction and a plurality of rows are arranged in parallel in the transverse direction; The buoyancy prevention transverse reinforcing bar 12 has a shape bent so that the convex portion 120 and the concave portion 121 are alternately formed in a zigzag, so that a plurality of horizontal reinforcing bars are placed adjacent to each other in the hollow module 1 It is disposed in the transverse direction so that each of the convex portions 120 surround the upper portion of the lightweight material 11; The fixed vertical reinforcing bars 13 are arranged across a plurality of buoyancy-preventing transverse reinforcing bars 12 in the longitudinal direction in a state in which the buoyancy-preventing transverse reinforcing bars 12 are arranged in parallel with each other in the longitudinal direction. Is coupled with the buoyancy prevention transverse reinforcing bar 12; The bar chair 14 is assembled and coupled to the concave portion 121 of the buoyancy-preventing transverse reinforcing bar 12 to support the longitudinal tension member 2, but consists of an upright bar member, and the lower end is made of a buoyancy-preventing transverse reinforcing bar 12 ) Consisting of a vertical member 141 and a rod member assembled and coupled to the concave portion 121 of the vertical member 141 and disposed in the transverse direction from the upper end of the vertical member 141, and are coupled, and one or both ends of the transverse direction is a buoyancy-preventing transverse reinforcing bar ( 12) and is configured to include a horizontal member 142 assembled and coupled;

상기 수직부재(141)의 측면에는 상기 종방향 긴장재(2)가 끼워져서 종방향 긴장재(2)의 외부를 감쌀 수 있도록 오목하게 곡선진 U자형 체결부(15)가 복수개로 형성된 구조를 가지게 된다.The vertical tension member 2 is fitted on the side surface of the vertical member 141 to have a structure in which a plurality of concave curved U-shaped fastening portions 15 are formed to wrap the outside of the longitudinal tension member 2 .

그런데, 이러한 구조는 종방향 긴장재(2)를 고정하는 바 체어(14)가 부력방지 횡철근(12)에 고정되는 구조로서, 슬래브(100) 상에 부력방지 횡철근(12)과 고정용 종철근(13)이 배근된 상태에서 바 체어(14)가 부력방지 횡철근(12)에 고정된 후 종방향 긴장재(2)가 배근되어야 하므로, 반드시 부력방지 횡철근(12)에 결합되어야 하는 구조를 가진다.However, this structure is a structure in which the bar chair 14 for fixing the longitudinal tension member 2 is fixed to the buoyancy-preventing transverse reinforcing bar 12, and the buoyancy-preventing transverse reinforcing bar 12 and the fixed longitudinal reinforcing bar 12 on the slab 100 Since the bar chair (14) is fixed to the buoyancy-preventing transverse reinforcing bar (12) while the reinforcing bar (13) is reinforced, the longitudinal tension member (2) must be reinforced, so it must be coupled to the buoyancy-preventing transverse reinforcing bar (12). Have.

따라서, 종래의 바 체어(14)는 부력방지 횡철근(12)과 관계없이 슬래브(100)에 독립적으로 자립하여 종방향 긴장재(2)를 고정할 수 없어서 시공이 매우 복잡해 진다.Therefore, the conventional bar chair 14 is independent of the buoyancy-preventing transverse reinforcing bar 12 and is independent of the slab 100 and cannot fix the longitudinal tension member 2, making construction very complicated.

즉, 부력방지 횡철근(12)과 고정용 종철근(13)을 모두 배근한 상태에서 바 체어(14)를 부력방지 횡철근(12)에 조립한 후 종방향 긴장재(2)를 끼워서 고정시켜야 되므로 그 공정이 매우 복잡하게 되어 시공성이 나쁘고, 또한 이로 인하여 작업효율이 많이 저하되는 문제점이 있다.That is, after assembling the bar chair 14 to the buoyancy-preventing transverse reinforcing bar 12 with both the buoyancy-preventing transverse reinforcing bar 12 and the fixing longitudinal reinforcing bar 13 placed in place, the longitudinal tension member 2 should be inserted and fixed. Therefore, there is a problem in that the process is very complicated and the workability is poor, and the work efficiency is greatly reduced due to this.

아울러 콘크리트 타설시 체결부(15)로부터 종방향 긴장재(2)가 쉽게 이탈하게 됨으로써 시공 불량의 소지를 안고 있다.In addition, since the longitudinal tension member 2 is easily separated from the fastening part 15 during concrete pouring, there is a possibility of poor construction.

따라서, 본 고안은 종래의 이러한 문제점을 해결하기 위하여, 슬래브 상에 독립적으로 자립하여 긴장재를 안정적으로 고정시킬 수 있도록 함과 아울러 긴장재와 교차되어 배근되는 철근도 안정적으로 고정시킬 수 있도록 한 콘크리트 슬래브용 긴장재 고정장치를 제공하고자 한다.

Figure 4 is a view showing the structure of the present invention, Figure 5 is a view showing a structure in which the tension member is fixed to the present invention, Figure 6 is a view showing a state in which reinforcing bars are fixed to the present invention, and the body 200 A floor support part 210 is provided to stably maintain an erected state in order to stand alone from the bottom of the slab, and the floor support part 210 is formed to further extend outward from the lower part of the body 200.

몸체(200)의 상측에는 종방향으로 복수의 긴장재(300)가 안착될 수 있도록 몸체(200)의 횡방향으로 복수의 안착홈(220)이 나란히 형성되는데, 이러한 안착홈(220)은 강선 등의 긴장재(300)를 하측부위를 안착시킬 수 있도록 반원의 형태를 가지게 된다.On the upper side of the body 200, a plurality of seating grooves 220 are formed side by side in the transverse direction of the body 200 so that a plurality of tension members 300 can be seated in the longitudinal direction, such a seating groove 220 is a steel wire, etc. It has the shape of a semicircle so that the lower part of the tension member 300 can be seated.

또한, 상기 안착홈(220)이 형성된 부위에서 몸체(200)의 양측부 즉 횡방향으로의 양측부에는 각각 결속돌기(230)가 형성되어 있어서, 이 결속돌기(230)에 긴장재(300)를 안착홈(220)으로부터 이탈되지 않도록 결속시켜 고정하는 결속선(240)의 양측이 각각 결속된다.In addition, since the binding protrusions 230 are respectively formed on both sides of the body 200 in the region where the seating groove 220 is formed, that is, both sides in the transverse direction, the tension member 300 is formed in the binding protrusion 230 Both sides of the binding line 240 that is bound and fixed so as not to be separated from the seating groove 220 are bound, respectively.

그리고, 상기 몸체(200)에는 관통된 결속구멍(250)이 복수개가 형성되어 있는데, 이러한 결속구멍(250)과 긴장재(300)가 와이어로 연결되어 고정시키도록 한다. In addition, the body 200 has a plurality of binding holes 250 penetrated therethrough, and the binding holes 250 and the tension member 300 are connected with a wire to be fixed.

상기 몸체(200)의 전면 및 후면에는 각각 철근거치부(260,261,270,271)가 형성되어 있는데, 이러한 철근거치부(260,261,270,271)는 몸체(200)의 전면과 후면에서 각각 서로 간격을 두고 한 쌍으로 형성되어 있게 된다.The front and rear of the body 200 are each formed with reinforced brackets (260, 261, 270, 271), and these reinforced brackets (260, 261, 270, 271) are formed in pairs at the front and rear of the body 200 at intervals from each other. do.

즉, 철근(400)을 긴장재(300)와 교차되도록 횡방향으로 배근할 때 상기 철근거치부(260,261,270,271)에 거치하여 안정적으로 배근이 가능하게 된다.That is, when reinforcing the reinforcing bar 400 in the transverse direction so as to intersect with the tension member 300, the reinforcing bar is mounted on the reinforcing bar holders 260, 261, 270, and 271 so that the reinforcing bar is stably possible.

이러한 전면과 후면에 각각 형성된 철근거치부(260,261)(270,271)는 그 높이를 달리하게 되는데, 전면의 철근거치부(260,261)는 몸체(200)의 하단부위로부터 30mm 정도의 위치에 있으며, 후면의 철근거치부(270,271)는 몸체(200)의 하단부위로부터 40mm 정도의 위치에 있게 되어 철근(400)의 높이가 다르게 배근이 가능한 것이다.The reinforcement brackets (260, 261) (270, 271) formed on the front and rear sides, respectively, have different heights, and the reinforcement brackets (260, 261) on the front are located at about 30mm from the lower part of the body 200, and The reinforcing rod holders 270 and 271 are located at a position of about 40 mm from the lower end of the body 200 so that the reinforcement can be reinforced with a different height of the reinforcing bar 400.

이러한 본 고안의 사용상태를 설명한다.The state of use of the present invention will be described.

도5에서와 같이 몸체(200)를 복수의 안착홈(220)이 횡방향을 향하도록 슬래브에 세워 놓은 상태에서, 그 안착홈(220)에 긴장재(300)를 놓아 배치한 다음 결속선(240)의 일측을 결속돌기(230)에 묶어서 결속시키고, 그 일측이 결속된 결속선(240)을 긴장재(300)의 상측을 가로지른 후 그 타측을 결속돌기(231)에 당겨서 결속시킴으로써 긴장재(300)가 이탈이 되지 않도록 한다.5, in a state in which the body 200 is erected on the slab so that the plurality of seating grooves 220 face in the transverse direction, the tension member 300 is placed in the seating groove 220, and then the binding line 240 ) To bind one side of the binding protrusion 230, and after crossing the upper side of the tension member 300 with the binding line 240 on which one side is bound, pull the other side to the binding projection 231 to bind the tension member 300 ) Does not deviate.

이러한 결속방법은 복수의 안착홈(220)에 긴장재(300)가 모두 안착된 상태에서 하나의 결속선(240)에 의해 결속시키는 방법이고, 긴장재(300)를 독립적으로 결속하기 위해서는 몸체(200)에 형성된 결속구멍(250)을 사용하게 된다.This binding method is a method of binding by a single binding line 240 in a state in which the tension member 300 is all seated in the plurality of mounting grooves 220, and in order to independently bind the tension member 300, the body 200 The binding hole 250 formed in is used.

이를 위해서 와이어를 결속구멍(250)에 끼운 다음 하나의 긴장재(300)의 상측을 일방향으로 감아서 다시 동일한 결속구멍(250)에 끼우고, 다시 긴장재(300)의 상측에서 와이어가 서로 교차되도록 'X'자 형태로 감은 다음 결속구멍(250)에서 와이어의 양끝을 묶어주면 된다.For this purpose, the wire is inserted into the binding hole 250, and then the upper side of one tension member 300 is wound in one direction, and then again inserted into the same binding hole 250, so that the wires cross each other at the upper side of the tension member 300. After winding it in an X'shape, tie both ends of the wire through the binding hole 250.

그러면, 몸체(200)에 하나의 긴장재(300)가 'X'자 형태로 묶여서 단단히 고정되는 것이다.Then, one tension member 300 is tightly fixed to the body 200 by being tied in a'X' shape.

아울러, 몸체(200)의 전면과 후면에 각각 형성된 철근거치부(260,261)(270,271)에는 긴장재(300)와 교차되도록 즉 횡방향으로 철근(400)이 안착되어 배근된다.In addition, the reinforcement brackets 260,261, 270,271 formed on the front and rear surfaces of the body 200, respectively, are reinforced with the reinforcing bar 400 mounted in the transverse direction so as to intersect with the tension member 300.

즉, 종래와 같이 철근을 배근한 다음 그 철근에 긴장재를 고정하기 위한 고정장치를 고정시키고, 그 고정장치에 다시 긴장재를 고정하는 것이 아니라, 본 고안에서는 먼저 고정장치를 슬래브에 세운 상태에서 긴장재(300)와 철근(400)을 한꺼번에 고정시킴으로써 시공이 매우 간편한 것이다.That is, as in the prior art, a fixing device for fixing a tension member to the reinforcing bar is fixed, and the tension member is not fixed to the fixing device again, but in the present design, the tension member ( By fixing 300) and the reinforcing bar 400 at once, the construction is very easy.
