CONSTITUTION: A non-sleeve PC member(100) for a structure comprises a plurality of sleeve assembling grooves(110). The inner circumference of the assembling groove is selectively joined to a PS steel wire, a PS steel rod, or a reinforcement bar(160) for embedding. The PS steel wire, the PS steel rod, and the reinforcement bar are joined to a spiral bar(120) on an internal line. The assembling groove is formed with an injection groove(140) and a discharge groove(150) for filling grout(130). The assembling groove is internally formed with a joint bar(11). The top end of the joint bar is partially embedded in the PC member. The bottom end of the joint bar partially protrudes to the inside of the assembling groove for being filled with the grout.

본 발명은 PC(Precast Concrete)화 구조물의 시공시 피씨기둥, 피씨 월 등과 같은 각종 PC부재를 연결함에 있어서, 연결부에 일반적으로 사용되는 종전의 주물 슬리브를 생략 또는 제거하도록 하되, 상기 PC부재 내에 주물 슬리브를 대체할 수 있는 조립홈을 형성한 후 강성을 유지할 수 있도록 나선근(스파이럴 철선) 및 강봉을 매입하여 다층 연결을 도모하도록 함으로써, 종전 대비 PC부재 제작에 따른 원가를 절감할 수 있는 바, 이는 경제성과 생산성이 향상되는 것을 특징으로 하는 구조물용 논 슬리브 피씨부재에 관한 것이다.
The present invention is to omit or remove the conventional casting sleeves generally used in the connection portion in connecting various PC members such as PC pillar, PC wall, etc. when the construction of the PC (Precast Concrete) structure, the casting in the PC member After forming the assembling groove to replace the sleeve, it is possible to reduce the cost of manufacturing PC members compared to the past by purchasing spiral wires (spiral wire) and steel bars to maintain the rigidity, thereby establishing a multi-layered connection. This relates to a non-sleeve PC member for a structure, which is characterized in that economy and productivity are improved.

일반적으로 지하주차장을 포함한 공공시설물 또는 공공주택 등의 구조물을 시공하는 경우에는 많은 하중이 요구되므로, 하프 슬래브(Half PC Slab), 피씨 기둥, 피씨 월을 이용한 PRC(Precast Reinforced Concrete Layer Construction Method) 복합화 공법 등이 실시되고 있다.In general, when constructing public facilities including underground parking lots or structures such as public housings, a lot of loads are required. Therefore, a composite PRC (Precast Reinforced Concrete Layer Construction Method) using a half slab, a PC column, and a PC wall is integrated. Construction methods are carried out.

이러한 PC 복합화 공법은 철근 콘크리트 라멘(Rahmen) 구조물을 PC(Precast Concrete)화하는 공법으로서, 공장에서 제작한 PC기둥, PC보, 하프 슬래브 등 PC부재를 현장으로 운송, 양중하여 조립한 후 부재 간 접합부와 하프 슬래브의 상부에 덧침 콘크리트를 현장에서 타설하여 구조체를 일체화시키도록 형성된다.The PC compounding method is a method of converting reinforced concrete ramen structures into PCs (Precast Concrete) .The PC components such as PC columns, PC beams, and half slabs manufactured at the factory are transported, lifted, assembled, and then assembled between the members. On top of the joint and the half slab is poured concrete in the field is formed to integrate the structure.

이에, 다층 구조의 구조물들은 상기 PC부재의 연결을 위해 맞닿는 각 연결 부위마다 주물로 형성된 슬리브를 매입하고, 상기 매입된 슬리브의 내부로 주근 또는 연결근이 삽입되면 무수축 몰탈 등에 의해 접합되도록 형성된다.Therefore, the multi-layered structures are formed to embed a sleeve formed of a casting for each connection portion to be contacted for the connection of the PC member, and to be joined by shrinkage mortar or the like when the main or connecting muscle is inserted into the embedded sleeve. .

그러나, 이와 같은 주물 슬리브는 중량이 상당하여 PC부재를 제작함에 있어서, 작업상 지지하면서 정밀한 현장 맞춤하기가 곤란하였으며, 특히 주물 슬리브 자체의 단가가 적지 않은 고가이기에 PC부재의 제작 원가 역시 상승되는 문제가 계속되어오고 있는 실정이다.
However, since the casting sleeve has a considerable weight, it is difficult to precisely fit the site while supporting the work in manufacturing the PC member. In particular, since the cost of the casting sleeve itself is not high, the manufacturing cost of the PC member also increases. Has been going on.

즉, 프리캐스트 콘크리트(Precast Concrete)로 형성된 PC부재(100)의 일면에 수직으로 기립한 타측 PC부재(100-1)의 주근 또는 연결근(10)이 인입 및 매립된 후 양생되도록 일단이 개구된 다수개의 슬리브용 조립홈(110)이 형성되되, 상기 조립홈(110)의 내주면에는 다수개의 PS강선, PS강봉, 철근(160) 중 어느 하나가 선택적으로 결합되어 조립홈(110)의 길이방향과 대응되도록 기립하면서 매입되도록 형성된다.That is, one end is opened so that the main or connecting muscle 10 of the other PC member 100-1 standing upright on one surface of the PC member 100 formed of precast concrete is cured after being drawn in and embedded. A plurality of sleeve assembly groove 110 is formed, the inner peripheral surface of the assembly groove 110 any one of a plurality of PS steel wire, PS steel rod, reinforcement 160 is selectively coupled to the length of the assembly groove 110 It is formed to be embedded while standing up to correspond to the direction.

이때, 상기 PS강선, PS강봉, 철근(160)의 내측 또는 외측 선상에는 나선근(120)이 조립홈의 길이방향으로 따라 결합되도록 형성되어 상기 조립홈(110)의 구조 강성을 지지하도록 형성되고, 상기 조립홈(110)의 일측 및 타측에는 그라우트(130)가 충진되도록 주입공(140)과 배출공(150)이 형성되며, 상기 슬리브용 조립홈(110)에는 타측 PC부재(100-1)의 주근 또는 연결근(10)과 동일한 선상으로 매립된 연결이음근(11)이 형성되되, 상기 연결이음근(11)의 상단 일부는 PC부재(100) 상에 매립되고, 하단 일부는 조립홈(110) 내부로 돌출되어 상기 주근 또는 연결근(10)과 마주보는 상태에서 그라우트(130)로 하여금 양생되도록 형성된다.At this time, the inner side or the outer line of the PS steel wire, PS steel bar, reinforcement 160 is formed to be coupled along the longitudinal direction of the assembling groove 120 is formed to support the structural rigidity of the assembly groove 110 The injection hole 140 and the discharge hole 150 are formed at one side and the other side of the assembly groove 110 to fill the grout 130, and the other assembly PC member 100-1 is disposed at the sleeve assembly groove 110. A connecting joint root 11 embedded in the same line as the main root or connecting muscle 10 of the) is formed, the upper part of the connecting joint root 11 is embedded on the PC member 100, the lower part is assembled Protruding into the groove 110 is formed to cure the grout 130 in a state facing the main or connecting muscle 10.

즉, 본 발명의 다른 실시예는 상술한 일 실시예와 달리 조립홈 내부에 강선, 강봉, 철근과 함께 나선근이 결합된 상태의 것으로, 이는 조립홈 내부로 인입된 주근 또는 연결근과 함께 그라우트로 하여금 일체로 양생되도록 구성된다.That is, another embodiment of the present invention, unlike the embodiment described above, is a state in which the spiral wires are coupled with steel wires, steel bars and reinforcing bars in the assembly grooves, which are grouted together with the main or connecting muscles introduced into the assembly grooves. It is configured to cure integrally.

이때, 상기 PS강선, PS강봉, 철근(160)은 길이방향 상단 및 하단에 걸림구(161)에 의해 결합된 유동방지용 플랜지(162)가 형성되어 슬리브용 조립홈(110) 내에서 견고한 접합 고정을 이루도록 하는 것이 바람직하다.At this time, the PS steel wire, PS steel bar, the reinforcement 160 is formed in the upper and lower longitudinal flow prevention flange 162 coupled by the locking hole 161 is fixed in the assembly groove 110 for the sleeve firmly fixed It is desirable to achieve this.

또한, 상기 주근 또는 연결근과 연결이음근(10,11)은 슬리브용 조립홈(110) 내에서 그라우트(130)에 의해 양생시 합성 면적이 확대되도록 외주면에 리브(12)가 형성되어 나선근(120)과 함께 합성 인장력과 압축력을 배가시키도록 하는 것이 바람직하다.In addition, the main root or the connecting muscle and the connecting joint (10, 11) is a spiral 12 is formed on the outer circumferential surface of the ribs 12 so that the compounding area is expanded by the grout 130 in the sleeve assembly 110 for curing It is desirable to double the combined tensile and compressive forces with 120.

아울러, 상기 슬리브용 조립홈(110)은 도 5에 도시된 바와 같이, PC부재의 연결이음근(11)의 하단부까지 미리 프리캐스트 콘크리트(Precast Concrete)로 형성되어 그라우트가 하부측 주근 또는 연결근에만 충진되도록 하는 것이 바람직하다.In addition, as shown in Figure 5, the sleeve assembly groove 110 is formed of precast concrete (Precast Concrete) to the lower end of the connecting joint 11 of the PC member in advance, the grout is the lower side root or connecting muscle It is desirable to be filled only.

이는 결국 조립홈 내로 충진되는 그라우트의 사용량을 절감할 수 있는 특징이 있다.
This is a feature that can reduce the amount of grout that is eventually filled into the assembly groove.

본 발명은 상술한 특정의 바람직한 실시예에 한정되지 아니하며, 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 고안이 속하는 기술분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변형실시가 가능한 것은 물론이고, 그와 같은 변경은 청구범위 기재의 범위 내에 있게 된다.
It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims and their equivalents.
