Description

트레스 까치발 설치공법{A METHOD OF CONSTRUCTING CLIMBING BRACKET}A METHOD OF CONSTRUCTING CLIMBING BRACKET}

본 발명은 콘크리트 고층 구조물 구축공사에 있어서 구조물의 수직도 조절 및 거푸집 설치 및 해체를 정확하고 안전하며 신속하게 행할 수 있는 트레스 까치발(3S-CLIMBING BRACKET)설치공법에 관한 것으로, 구체적으로는 콘크리트 구조물을 단계(층)별로 구축해 나감에 있어서, 기히 구축된 구조물에 매설 고정된 고정구(Anchor Cone)를 이용 여기에 이동식 트레스 까치발을 쉽게 결합하고 정확하게 수직도를 조절할 수 있는 수단 등을 구비한 트레스 까치발의 설치공법에 관한것이다.The present invention relates to a trestle bracket (3S-CLIMBING BRACKET) installation method that can accurately, safely and quickly perform the vertical control and form installation and dismantling of the structure in the construction of concrete high-rise structure, specifically In the construction of each level, the brace brackets are equipped with means for easily combining the movable brace brackets and precisely adjusting the verticality by using anchor anchors embedded in the structure. It's about public law.

종래 콘크리트구조물(고층건물)을 층단위로 구축해 나감에 있어서 까치발 설치공법은 도 1a에서와 같이 일명 갱폼거푸집(GANG FORM) 이라고 하는 외부거푸집(1)과 수직방향으로 밀착된 트레스 까치발(A)을 크레인(B)으로 끌어올린 후 거푸집 하측을 기히 타설 양생된 콘크리트 폼타이구멍(2)을 이용 타이볼트(3)와 너트(4)로 고정시킨 다음에 거푸집 상단을 조절 비닐밴드(5)에 고정시키고 상판슬라브나 벽체용 철근에다 비닐밴드(5)의 반대쪽 끝을 고정하고 조절용후크(HOOK) 고리(6)로 거푸집(1)의 수직도를 맞추도록 되어있고 수직도 조정작업이 끝나면 도 1b에서와 같이 내부거푸집(7)과 외부거푸집(1) 사이에 일정공간(몰탈타설부)이 확보되면서 내부거푸집(7), 외부거푸집(1), 외부거푸집과 밀착된 까치발지지판(8)이 수십개의 타이볼트(3)에 의하여 각각의 구멍으로 관통되어 내외측에서 너트(4)로 체결되므로서 슬라브 거푸집(9)과 함께 설치된후 콘크리트 몰탈이 타설되고 수일이 경과하여 한층의 콘크리트 구조물(벽체 및 슬라브)이 양생되어 강도를 같게된다.In the construction of conventional concrete structures (high-rise buildings) in units of floors, the bracket installation method is a tress bracket (A) in close contact with the vertical formwork (1) called a gang form (G) as shown in Figure 1a. After pulling up to the crane (B), fasten the bottom of the formwork with the tie-shaped bolt (3) and the nut (4) using the cured concrete form tie hole (2), and then fix the top of the formwork to the adjusting vinyl band (5). After fixing the opposite end of the vinyl band (5) to the top slab or wall reinforcing bar, and to adjust the verticality of the formwork (1) with the adjustment hook (6), and when the verticality adjustment work is finished in Figure 1b As a certain space (mortar mortar part) is secured between the inner formwork (7) and the outer formwork (1), the inner formwork (7), the outer formwork (1), and the magpie foot support plate (8) in close contact with the outer formwork dozens of Each hole by tie bolts (3). After being installed with the slab formwork 9 by being fastened with nuts 4 at the inside and the outside, concrete mortar is poured and several days later, one layer of concrete structures (walls and slabs) are cured to have the same strength.

이상과 같은 상태에서 해체작업을 하기 위해 크레인(B)에 까치발을 고정시킨 상태에서 내부거푸집(7)과 외부거푸집(1) 및 까치발의 지지판(8)을 고정시키고 있는 타이볼트(3)를 전부 제거하고 크레인(B)로 한층을 끌어올려 새로 축조된 구조물의 벽체 상측부에 형성되어있는 구멍을 통하여 타이볼트(3)으로 벽체 외부거푸집하측부, 까치발의 지지판을 관통시켜 고정하는 작업으로 도 1a와 같은 설치작업을 반복하는 까치발 설치공법이다.In order to perform the dismantling work in the above state, all of the tie bolts 3 fixing the inner formwork 7 and the outer formwork 1 and the support plate 8 of the restoring feet in the state where the bracket foot is fixed to the crane B are fixed. Removing and pulling up one layer with the crane (B) through the hole formed in the upper part of the wall of the newly constructed structure by the tie bolts (3) through the outer wall of the lower formwork, and to fix the support plate of the bracket feet Figure 1a It is the installation method of the crow's feet to repeat the installation work.

이상의 까치발(A)의 구조는 수직으로 강지주(A1), 횡으로는 강지보(A2), 까치발의 상측 양측에 고정되고, 크레인(B)에 걸수 있도록한 와이어 또는 체인(A3)이 마련되어있고, 전면에는 지지판(8)과 지지판에 밀착된 외부거푸집(1)으로 구성되어있고 밀착된 지지판(8)과 외부거푸집(1)에는 일치되게 타이볼트(3)을 관통할 수 있는 구멍들이 수십개 형성되어있다.The structure of the above-mentioned bracket foot A is fixed to the steel column A1 vertically, the steel beam A2 horizontally, and fixed to both upper sides of the bracket foot, and the wire or the chain A3 which can be hooked to the crane B is provided, The front surface is composed of a support plate 8 and an external formwork (1) in close contact with the support plate, and the support plate (8) and the external formwork (1) in close contact are formed with dozens of holes that can penetrate the tie bolts (3). have.

이와 같은 까치발의 설치공법은 도 1a에서와 같이 크레인(B)에 까치발이 메달린 상태에서 구조물(벽체)에 뚫어진 구멍으로 돌출되는 타이볼트를 외부거푸집(1)밀착된 지지판(8)을 관통시켜 고정하는 작업이 까다롭고 이에 따라 크레인을 사용하는 시간이 길어지며 비닐밴드로 수직도를 조절한후 내부거푸집 설치시 비닐밴드가 장애요소가 되며, 구조물(벽체)와 외부거푸집의 밀착력이 부족하여 몰탈액이 새어나오기 쉬우며 까치발 설치에 많은 시간이 소요되므로서 전체공기 또한 길어진다.This installation method of the bracket feet is as shown in Fig. 1a through the tie plate protruding into the hole drilled in the structure (wall) in the state of hanging the bracket (B) through the outer die (1) in close contact with the support plate (8) Fixing work is difficult and accordingly, it takes longer time to use crane, and after adjusting verticality with vinyl band, vinyl band becomes an obstacle when installing inner formwork, and mortar due to lack of adhesion between structure (wall) and outer formwork. It is easy for the liquid to leak out, and it takes a lot of time to install the crow's feet.

본 발명은 종래 까치발 설치공법의 문제점들은 해결한 트레스 까치발의 설치공법을 제공함에 있어서 구체적으로는 이미 축조된 구조물에 고정구를 매몰 설치하므로서 트레스 까이발을 쉽게 공정 설치함과 동시에 수직도 맞춤을 정확하게 할 수 있는 트레스 까치발을 사용하므로서 트레스 까치발의 설치작업을 신속하고 안전하게 할 수 있으며 정확한 수직도를 유지하고 하부 거푸집 하측면을 구조물 벽체면에 완벽하게 밀착시켜 몰탈액의 누출을 방지하여 정밀시공과 공기를 단축시킬 수 있는 트레스 까치발의 설치공법을 제공함에 있다.The present invention provides an installation method of the tress bracket foot that solves the problems of the conventional bracket foot installation method. The installation of tress bracket feet enables fast and safe installation of the tress bracket feet, and maintains the correct verticality and perfectly adheres the lower formwork to the wall of the structure to prevent the leakage of mortar. It is to provide a method of installing the tress bracket feet that can be shortened.
