自动门应注意的质量问题。
Attention should be paid to the quality problems of automatic doors.
1.电子感应自动门科技含量较高，其机械装置、自动化装置或智能化装置可靠性优劣相差悬殊，价格也就相差甚远，为了确保正常使用少故障，耐用而安全，应尽可能选用知名企业的品牌产品。
1. Electronic induction automatic door has high technology content, and its mechanical device, automation device or intelligent device have different reliability and price. In order to ensure normal use, less faults, durability and safety, we should choose brand products of well-known enterprises as far as possible.
2.对于装有导向性下轨道的自动门宜在地坪施工时抄平划线，在自动门下轨道位置精确地预埋木枋，并注意木枋长度大于开启门宽的2倍，不宜采用后剔槽的方式，以确保槽口质量及下轨与地坪交接处美观。
2. For the automatic doors equipped with guided lower tracks, it is advisable to copy the horizontal lines during the construction of the ground, embedding the wooden foliage accurately in the position of the track under the automatic doors, and paying attention to the length of the wooden foliage is more than twice the width of the open doors. It is not advisable to adopt the way of back grooving to ensure the quality of the groove entrance and the beautiful junction between the underground tracks and the ground.
3.自动门上部钢横梁安装是安装过程中的重要环节，装有机械装置和电控装置的机箱固定在其上，故要求钢梁及钢梁与洞侧连接有一定的强度、刚度和稳定性。井盖钢模具 U型槽模具 天津水处理设备 检查井钢模具 保定公司注册 u型槽模具 流水槽模具如前期施工图中设计深度不足，主体结构施工中必须与设计人员联系落实。钢横梁两端连接预埋件应可靠地锚固在钢筋砼构件中。
3. Installation of steel beam on top of automatic door is an important link in the installation process. The box equipped with mechanical device and electronic control device is fixed on it. Therefore, it is required that the connection of steel beam and steel beam with tunnel side has certain strength, stiffness and stability. If the design depth in the previous construction drawings is insufficient, the main structure construction must be carried out in contact with the designers. The embedded parts connecting the two ends of the steel beam should be anchored in the reinforced concrete members reliably
