Problems solved by technology
The advantage of the embedded sleeve combined with the T-shaped head connection is that it is easy to install, the connection is firm, and it can meet the requirements of the production process. During this period, the settlement and displacement of the equipment foundation are unavoidable, especially the displacement of the equipment foundation constructed on soft soil foundation is uncontrollable
Furthermore, there are inevitable errors in the installation of pre-embedded anchor bolts during the civil construction stage, and it is difficult to meet the requirements of equipment installation accuracy
Since the center position of the embedded sleeve is not known in advance, after the equipment arrives at the site, it cannot be installed due to the offset of the sleeve position
There is currently no effective countermeasure against this situation.

Embodiment 1
[0023] A method for precisely measuring the center position of a pre-embedded sleeve, which is characterized in that: the following steps are carried out sequentially:
[0024] a. Make simulated bolts: simulated bolt 1 such as figure 1 and figure 2 As shown, it is made of steel pipe and steel plate, the screw rod 11 of the simulated bolt 1 is made of steel pipe, and the bolt head 12 of the simulated bolt 1 is as image 3 As shown, it is welded and spliced by steel plates. The steel plates include a bottom plate 121, two square side plates 122, two arc side plates 123 and an arc top plate 124. The shapes of the bottom plate 121 and the square side plate 122 are both rectangular. The shape of the plate 123 is connected to a bow on one side of the rectangle, the arc of the arc top plate 124 is the same as that of the arc side plate 123 arc, and one side of the square side plate 122 is respectively fixed on both sides of the two parallel opposite sides of the bottom plate 121,...

The invention relates to a diameter measuring method, which belongs to the field of linear size measurement, in particular to a method for precisely measuring the central position of an embedded sleeve. The method for precisely measuring the central position of the embedded sleeve is characterized by comprising the following steps of: a, manufacturing a simulation bolt; b, arranging the simulation bolt; c, measuring the central position; and d, determining a practical central position. Through the method, the central position of the embedded sleeve which is embedded in a concrete equipment base can be measured accurately, and smooth equipment installation and high-accuracy equipment installation are ensured.
Description
technical field [0001] The invention relates to the field of diameter measurement methods in linear dimension measurement, in particular to a method for precisely measuring the center position of an embedded sleeve. Background technique [0002] The connection and fixation of modern large-scale electromechanical equipment and concrete equipment foundation generally adopt the form of T-head bolts combined with embedded sleeves. For example, the large-scale rolling mill production line of a smelter has a rolling force of 10,000t. Correspondingly, the quality of the equipment And the volume is relatively large, and the connection between the rolling mill stand and the equipment foundation is mostly in this form. The advantage of the embedded sleeve combined with the T-shaped head connection is that it is easy to install, the connection is firm, and it can meet the requirements of the production process. During this period, the settlement and displacement of the equipment found...
