Description

Wood-metal mixed adjustable template diagonal bracing system and construction method Technical Field The invention relates to a template diagonal bracing system and a construction method, in particular to a wood-metal mixed adjustable template diagonal bracing system and a construction method. Background In the construction of constructional engineering, the concrete side wall, the shear wall and the high and large formwork bear larger lateral pressure in the concrete pouring process, and in order to ensure the stability of the formwork structure, a temporary diagonal bracing structure is usually required to be arranged on the outer side of the formwork for supporting. At present, the construction site is generally formed by manually combining materials such as battens, steel pipes or bamboo poles and the like to form an inclined strut system, and the structure is mostly erected by relying on site experience and has the following technical problems: First, the support angle is not adjustable or the adjustment accuracy is low. Most of the existing diagonal bracing structures are erected at fixed angles, and cannot be flexibly adjusted according to working conditions such as wall height, foundation gradient and the like. Although the part of the adjustable diagonal bracing structure has an adjusting function, most of adjusting modes are driven by threaded rods, adjusting precision is limited by thread pitches, and effective coordination with template interval control is lacking. Second, the thickness of the reinforcement protection layer is difficult to control. The traditional diagonal bracing structure lacks special spacing adjusting component, and the interval control between template and the concrete side wall adopts wooden wedge to temporarily adjust more, and the precision is low, easily shift, leads to the reinforcing bar protective layer thickness deviation big, influences concrete structure durability. The existing protective layer cushion block can fix the position of the reinforcing steel bar, but the thickness is fixed and cannot be adjusted, so that the protective layer cushion block cannot adapt to the requirements of different protective layer thicknesses. Thirdly, the material loss is large and the repeated use rate is low. The traditional diagonal bracing system adopts disposable wood Fang Dashe more, and the flitch is easy to crack and damage after the disassembly, and the material waste is serious. Although reusable, metal diagonal braces lack an effective combination with wood support.
