Embodiment Construction

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

[0050] The invention provides a gas turbine base fixing device and an anchor bolt installation method. The base fixing device still has a large adjustment range after grouting is completed, and 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 makes installation convenient and flexible adjustment, which shortens the period of unit installation and adjustment, and is also conducive to later maintenance and changes.

[0051] ginseng Figure 1-3 As shown, in one aspect, the present invention provides a device for fixing a gas turbine base, including a load-bearing part structure, a pre-embedded part structure and a tightening structure.

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

Abstract

The invention relates to a gas turbine base fixing device and a fixing device installation method. The device includes a load-bearing structure, a built-in structure and a tightening structure; The seat is connected with the embedded plate; the embedded plate is used to fix the gas turbine base; the embedded part structure includes sleeve, channel steel I and bottom bracket; the tightening structure includes anchor bolts and nuts, and the method is as follows: After the embedded parts are welded, they are shipped to the site. After positioning, use a spirit level to ensure that the levelness of the channel steel is within the tolerance range, and perform a grouting. After the concrete is cured, you can put in the T-shaped anchor bolts and screw them to the limit. the baffle and tighten the nuts. The above-mentioned invention uses the embedded part structure, which can improve the control of the positional deviation of the entire embedded part in the process of pouring concrete, thereby ensuring high installation accuracy of the embedded part.

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 gas turbine units, the anchor bolts undertake the function of ensuring the level and positioning of the unit, especially as the benchmark for the level adjustment of the stator. Therefore, the quality of the anchor bolt construction will directly affect the operation of the unit. Especially for large gas turbine units, the installation accuracy of anchor bolts has a greater impact on the stability of the unit's operation. [0003] Embedded parts are components pre-installed in concrete, which are mainly used as connecting parts or building parts for anchor bolts in the subsequent construction process. At the construction site, due to the poor stability of steel bars and temporary supports, the impact force generated during the pouring of concrete will impact th...
