一般乡镇混凝土构件生产企业存在的质量通病是:产品结构性能与外观、几何尺寸波动幅度大,质量稳定性差,有的偏离国家标准,质量通病反映在生产工艺上,主要存在以下四个方面的问题。一、张拉台座的建造张拉台座一般由承力结构(墩、构架、桩等)、横梁及台面组成。承力结构是受拉横梁的依托,应具有抗倾覆、抗滑移和相应的强度;横梁是直接承受钢筋张拉力的,亦应有符合构件要求的强度和刚
General quality problems of production of concrete components in townships and townships are: product structure performance and appearance, geometric size fluctuations, poor quality stability, and some deviate from national standards, quality problems are reflected in the production process, there are the following four issues . First, the construction of tension benches Tension benches are generally composed of bearing structures (piers, frames, piles, etc.), beams, and countertops. The bearing structure is supported by the pull beam and should have anti-overturning, anti-slip and corresponding strength; the beam is directly subjected to the tensile force of the steel, and it should also have the strength and rigidity that meets the requirements of the component.
