Foundation bolt of equipment foundation and preformed hole setting method
The invention discloses a foundation bolt of an equipment foundation and a preformed hole setting method. The method specifically comprises the following steps: 1, designing a foundation bolt with a longitudinal convex rib; 2, reserved holes are formed; and 3, hole reserving and foundation bolt placing are completed. The strength of the embedded foundation bolt is improved, compared with a plain round screw rod, the side area of the screw rod with the longitudinal convex ribs is increased, the side friction resistance is also large, the uneven surface of the screw rod is beneficial to bonding with concrete, and when the bolt is subjected to the action of tension or pressure, the anchoring performance and stability of the foundation bolt with the longitudinal ribs are obviously superior to those of a common plain round screw rod; the construction technology is simple, the formed preformed hole and the pulling type plug body can be repeatedly used, the cost is effectively reduced, the work efficiency is improved, and the method is suitable for foundation bolt construction needed by static or small-vibration equipment with the preformed hole depth not larger than 0.5 m.
本发明公开了一种设备基础的地脚螺栓及预留孔设置方法。属于设备基础领域，具体步骤：1、设计带纵向凸肋的地脚螺栓；2、设置预留孔；3、完成预留孔及放置地脚螺栓。本发明预埋的地脚螺栓强度提高，与光圆螺杆相比，带纵向凸肋的螺杆侧面积增大，侧摩阻力也较大，螺杆表面不平整有利于与混凝土的粘结，在螺栓受到拉力或压力作用时，带纵肋的地脚螺栓的锚固性和稳定性明显优于一般光圆螺杆；本发明施工工艺简单、开设的预留孔、抽拔式塞体可重复使用，有效降低了成本，提高了工效，适用于预留孔深不超过0.5米，静止或振动小的设备所需的地脚螺栓施工。
