北京科技大学燕郊冶金实验厂1000kg和750kg锻锤基础,生产工艺要求:首先,基础的锤砧凹槽(1000kg为1100mm×2266mm,深1175mm,750kg为930mm×2100mm,深712mm)顶面,不得用水泥砂浆找平层;其次,顶面每米的不水平度≤0.5mm。在《钢筋混凝土工程施工及验收规范》中规定:每米允许偏差5mm,全长为10mm。两者相比,生产工艺要求仅为施工及验收规范的1/10。这样的水平度,不用水泥砂浆找平层,实际上是
Beijing University of Science and Technology Yanjiao Metallurgical Experimental Factory 1000kg and 750kg forging hammer foundation, production process requirements: First, the base of the hammer anvil groove (1000kg is 1100mm × 2266mm, depth 1175mm, 750kg is 930mm × 2100mm, depth 712mm) top surface, shall not be used The cement mortar leveling layer; secondly, the non-levelness per meter of the top surface is ≤ 0.5 mm. In the “Code for Construction and Acceptance of Reinforced Concrete Works,” it is stipulated that the allowable deviation per meter is 5 mm and the overall length is 10 mm. Compared with the two, the production process requirements are only 1/10 of the construction and acceptance standards. This level, without the cement mortar leveling layer, is actually
