Abstract

An embedding precise positioning method for a pot calciner steel structure strut foundation bolt is characterized by comprising the following steps that a, a positioning frame is prefabricated; b, a positioning stand rod (7), a positioning cross rod (8), a positioning longitudinal rod (9) and a wood padding block (10) are prefabricated; c, longitudinal and transverse center lines are made in a concrete foundation (1) in a popping mode; d, the foundation bolt (2) is put into a foundation bolt reserved hole; e, the wood padding block (10) is arranged; f, the positioning frame is installed; g, the positioning cross rod is fixed; h, the positioning longitudinal rod is fixed; and i, when an adjusting nut (16) is dismounted, the foundation bolt (2) is not rotated, and the embedding precise positioning of the pot calciner steel structure strut foundation bolt is achieved. The method has the advantages that the positioning frame device is simple in structure and convenient to manufacture, the step design of embedding construction of the foundation bolt is reasonable, steps are tightly connected and coordinated, the embedding precise positioning requirement of the foundation bolt is met, the mounting speed of a steel strut is increased, the use time of a crane is shortened, and the project cost is reduced.

Description

technical field [0001] The invention relates to a method for installing anchor bolts of industrial mechanical equipment, in particular to a method for pre-embedding and accurately positioning the anchor bolts of steel structure pillars of tank type calciner. Background technique [0002] The connection between the support of industrial machinery and equipment or the column foot of the equipment steel structure and the foundation through anchor bolts is a method of fixing equipment or equipment steel structures that is often used in construction. Specific to the pre-embedded project of anchor bolts of the construction unit, the anchor bolts are required to fix the steel structure pillars of the tank type calciner. There are 4 Φ200mm anchor bolt reserved holes on the foundation of each column, and the horizontal center distance of the bolt holes is 515mm, the longitudinal center distance is 450mm. figure 1 It is a schematic diagram of the pre-embedded requirements of the anch...
