Summary of the invention
The purpose of this utility model is exactly to solve the above problem existing for current steam turbine foundation built-in bolt sleeve fixed structure, provides a kind of construction simple and fast, the steam turbine foundation built-in bolt sleeve group fixed frame of registration for this reason.
Concrete scheme of the present utility model is: a kind of steam turbine foundation built-in bolt sleeve group fixed frame, it is characterized in that: there is main body fixed frame, main body fixed frame is welded several positioning units be arranged in array, each positioning unit forms vertical frame structure by four longerons and at least two-layer fixing horizontal frame be welded on four longerons, built-in bolt sleeve is set with in vertical frame, wherein fix horizontal frame to be made up of four crossbeams, every root crossbeam being all provided with one for fixing built-in bolt sleeve regulates the location adjusting bolt of built-in bolt sleeve verticality, prevent concrete from entering into the plug of built-in bolt sleeve when the lower port of built-in bolt sleeve is equipped with cast, in the bottom of vertical frame structure, chassis is housed, removable soffit formwork chassis is equipped with, soffit formwork is wooden structures and is bolted to connection with plug.
Plug described in the utility model has circular location-plate, location-plate is made up of the steel plate that 12mm is thick, the diameter of location-plate is greater than the internal diameter of built-in bolt sleeve, location-plate is uniformly distributed with along the circumference several reinforcing bar pawls, reinforcing bar pawl stretches in built-in bolt sleeve, and corresponding with built-in bolt sleeve inwall, reinforcing bar pawl is in order to fix and to firmly grasp built-in bolt sleeve.
Fix horizontal frame described in the utility model and there is square structure, and each location adjusting bolt is all corresponding with the axle center of built-in bolt sleeve.
The fixed frame of main body described in the utility model is welded by No. 20 channel-section steels and forms; Longitudinal and cross beam all adopts hem width to be 100mm, and limit is thick is the equal leg angle of 10mm; Location adjusting bolt adopts specification to be the hex bolts of M12.
The utility model has the following advantages compared with current steam turbine foundation built-in bolt sleeve fixed structure:
(1) the utility model by location adjusting bolt the adjustment of verticality is carried out to built-in bolt sleeve and location fixing, not only simple and fast, accurate positioning, and the built-in bolt sleeve Stability Analysis of Structures after overregulating location, the phenomenon of displacement and deflection is not easily there is in concrete pouring construction process, overcome current employing spot welding or binding strap fixes built-in bolt sleeve, make built-in bolt sleeve in concrete pouring construction process, there is the problem of deviations, absolute altitude deviation and perpendicularity deviation;
(2) adopt plug to not only ensure accurate positioning bottom built-in bolt sleeve in the utility model, and prevent in concrete pouring construction process, concrete enters into built-in bolt sleeve, causes the blocking to built-in bolt sleeve;
(3) in the utility model, chassis is after concrete casting injection forming, dismountable to facilitate turnover to use, and has greatly saved cost of production;
(4) constructing structure of the present utility model is more firm, overall good stress performance.
