Rapid clamping and fixing support for concrete beam body formwork and formwork erecting method
The invention belongs to the technical field of concrete beam formwork fixing, and particularly relates to a rapid clamping and fixing support for a concrete beam body formwork and a formwork erecting method. The rapid clamping and fixing support for the concrete beam body formwork comprises two opposite formworks, wherein formwork back ribs are arranged on the backs of the formworks; and push rods and pull rods are arranged on the parts, on the upper part of a beam body, of the formwork back ribs; and the pull rods are located between the beam body and the push rods. According to a traditional clamping and fixing method, opposite-pull screws are arranged at the bottom of the beam, so that the formworks bear inwards tensile force; and according to the scheme, outward horizontal pressure is applied to the tops of vertical ribs through harness screws, and the opposite-pull screws serve as turning points of force, so that inward pre-compressive stress is generated at the bottom of the beam, and lateral pressure of concrete is effectively resisted when the concrete is poured. The use of the opposite-pull screws is reduced, slurry leakage in the beam body pouring process is reduced, the blockage of the indwelling screws is avoided, form stripping is more convenient, and the surface of the beam body is smooth after form stripping. The construction is more convenient, the construction speed is high, and the method is suitable for factory-like batch production.
本发明属于混凝土梁模板固定技术领域，具体涉及一种混凝土梁体模板快速夹固支架和支模方法；包括两块相对的模板，模板的背部设置有模板背肋，模板背肋上在梁体上部设置有推杆和拉杆，拉杆位于梁体与推杆之间，传统的夹固措施是在梁底设对拉螺杆，使模板承受向内的拉力，本方案是在竖肋顶部通过通丝螺杆施加向外的水平压力，对拉螺杆作为力的转折点，从而使梁底部产生向内的预压应力，在浇筑混凝土时有效抵抗混凝土的侧向压力。减少了对拉螺杆的使用，梁体浇筑过程中减少了漏浆，没有留置螺杆的阻碍更方便拆模，拆模后梁体表面光滑。施工更加便捷，施工速度快，且适宜工厂化批量生产。
