The present invention can be easily manufactured to have a variety of shapes and a variety of reinforcement structure and to form a permanent reinforced frame of FRP, a fiber-reinforced plastic material exhibiting excellent tensile strength and lightweight to perform the role of permanent formwork and tensile reinforcement at the same time A composite beam filled with concrete in one FRP foam. 본 발명의 FRP 폼에 콘크리트를 충전한 합성보는 합성보를 구성하는 보형틀로 섬유강화플라스틱소재인 FRP를 성형하여 제작된 것을 채택한다는데 그 기술적 특징이 있다. 종래 FRP는 건축재료로서 보수보강용도로만 사용되어 왔으나, 본 발명에서는 본격적으로 구조재로서 활용하고 있다. FRP는 플라스틱소재이므로 공장에서 일정한 형상으로 성형 가공하는데 유리하고 그 성질상 가볍고, 열전도율이 낮으며, 내구성·내충격성·내마모성·인장강도 등이 우수하므로 본 발명에서와 같이 합성보를 구성하는 영구거푸집겸 인장재로 활용하기에 적합하다. 또한, FRP소재는 볼트접합만으로 간편하게 조립할 수 있으므로 그 현장작업이 상당히 간편해지며, 재료생산 및 부재제작시 강재에 비해 적은 에너지를 소모하므로 연료사용에 의한 환경문제를 최소화할 것으로 기대된다. The composite beam filled with concrete in the FRP foam of the present invention has a technical feature of adopting a fabricated frame made of a fiber reinforced plastic material, FRP, as a beam forming the composite beam. Conventional FRP has been used only for maintenance reinforcement as a building material, but in the present invention is utilized as a structural material in earnest. Since FRP is a plastic material, it is advantageous for molding processing to a certain shape in a factory, and is light in nature, low in thermal conductivity, and excellent in durability, impact resistance, abrasion resistance, tensile strength, and the like. It is suitable for use as a tension member. In addition, FRP material can be easily assembled only by bolted joint, so the field work is considerably simpler, and it is expected to minimize the environmental problems caused by the use of fuel because it consumes less energy than steel materials.

Stress-crack-resistant waterproof concrete ceiling construction - with slabs concreted onto beans subjected to prestressing during concreting

The purpose is to produce concrete ceilings with improved resistance to stress flaws, and thus with improved sealing against water penetration, esp. in park buildings and others exposed to severe weather conditions and drastic temperature fluctuations. A concrete slab, of ceiling or ceiling sections size, is produced by concreting on top of one or more beams which become anchored to it, these being exposed to prestressing forces during the concreting process, and exposed to tension on the side on which the concrete is to be set. The concrete slab is pressure-loaded by means of the beams when the forces are withdrawn after hardening. One or more such slabs are fitted on supports at the ends, to form a pressure-prestressed, sealed ceiling structure. This may be done directly on site.

Connector between wooden frame and concrete floor for restoration of old buildings

The casing may be shaped inside to fit the nail and the head of the nail rests on the casing. The casing is inserted in the wood through a hole (10) in the base of an angled connector (4) which is covered with the concrete when the slab is poured. The casing has a conical area (18) towards the top to slow down its insertion in the wood.

Double PC girder and construction method thereof

The present invention relates to a flat plate one-way structure type double precast concrete (PC) girder.

Therefore, the double PC girder can reduce manufacturing costs because remarkably reducing the use of concrete, strikingly save transportation costs and personnel expenses at the time of transportation and lifting, minimize interference between various interior materials such as electric facilities because the length of a ceiling part layer becomes higher, especially enhance productivity due to construction workability and reduction of a construction period, and greatly improve structural stability and quality.
