Embodiment Construction

[0049] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0050] The invention provides a gas turbine base fixing device and an installation method for anchor bolts. The base fixing device still has a large adjustment range after the grouting is completed, which can improve the control of the position deviation of the entire embedded part after pouring concrete , so as to ensure the installation accuracy of embedded parts. At the same time, the special anchor bolt structure enables convenient installation and flexible adjustment, shortens the installation and adjustment cycle of the unit, and is also conducive to later maintenance and changes.

[0051] ginseng Figure 1-3 As shown, on the one hand, the present invention provides a gas turbine base fixing device, including a load-bearing structure, a built-in structure and a tightening structure;

[0052] The load-bearing structure includes a pre-embedded board 1 a...

Abstract

The invention relates to a gas turbine base fixing device and a fixing device installing method. The gas turbine base fixing device comprises a bearing part structure, an embedded part structure and a tightening structure, wherein the bearing part structure comprises a pre-embedded plate and a pre-embedded plate supporting base, the pre-embedded plate supporting base is connected to the pre-embedded plate, the embedded plate is used for fixing a gas turbine base, the embedded part structure comprises a sleeve, channel steel I and a bottom bracket, the tightening structure comprises a foundation bolt and a nut, the method comprises the following steps that after the embedded part is welded, delivered to a site and positioned, it is ensured that the levelness of the channel steel is within the tolerance range through a gradienter, primary grouting is conducted, and after concrete is solidified, the T-shaped foundation bolt can be placed in and screwed to the limiting baffle, and the nut is tightened. By means of the gas turbine base fixing device and the fixing device installing method, the embedded part structure is used, control over the position deviation of the whole embedded part in the concrete pouring process can be improved, and therefore it is guaranteed that the installation precision of the embedded part is high.

Description

technical field [0001] The invention relates to the field of gas turbines, in particular to a gas turbine base fixing device and a fixing method. Background technique [0002] In the installation and construction of the gas turbine unit, the anchor bolts are responsible for ensuring the level and positioning of the unit, especially as a benchmark for the level adjustment of the stator. Therefore, the construction quality of the anchor bolts will directly affect the operation of the unit. Especially for large gas turbine units, the installation accuracy of the anchor bolts has a greater impact on the stability of the unit operation. [0003] Embedded parts are pre-installed components in concrete, mainly used as connectors or building parts for anchor bolts in the subsequent construction process. At the construction site, due to the poor stability of the steel bars and temporary supports, the impact force generated during the pouring of concrete will impact the embedded par...
