The anchor bolt cage runs through the whole wind power foundation, integrity, durability and fatigue resistance of the wind power foundation can be obviously improved by applying prestress, installation accuracy of the anchor bolt cage directly influences construction quality of the whole wind turbine foundation and safety of hoisting of wind turbine equipment, installation process of the upper flange directly influences installation quality of the whole anchor bolt cage, and the anchor bolt cage is an important link for relation between installation accuracy and safe use of the wind power tower.
The method for installing the upper flange of the anchor bolt cage on the basis of the existing wind turbine generator set is characterized in that nylon nuts in threaded connection with anchor bolts are sleeved on the anchor bolts below the upper flange. So, the cover is equipped with the sleeve pipe on the crab-bolt between last flange and the lower flange, follow-up accomplish concrete placement and the grout that excels in to the crab-bolt cage after, when stretching the crab-bolt, the nylon nut bears certain compressive stress after, the nylon part in the nylon nut can be pulled apart, makes whole crab-bolt receive even tensile stress. If use the stiffening nut, when stretching the crab-bolt, all fill high strength grout material because of upper flange lower part, the high strength grout material after solidifying also fixed connection with the upper flange, stress when can bearing tensile crab-bolt between stiffening nut and the upper flange lower part, so, the crab-bolt of upper flange below only receives less tensile stress, and the tensile stress that receives with the crab-bolt of upper flange top is inhomogeneous to also cause the harm to the upper flange easily. When using the nylon nut to fix the upper flange, because of the inside part that contacts with the crab-bolt of nylon nut is the nylon material, and with the upper flange installation back on the crab-bolt cage, carry out concrete placement after the crab-bolt cage need carry on for a long time, the nylon nut is easy to take place to warp at the junction with the crab-bolt, cause the upper flange levelness error, before carrying out the grout of excelling in to the upper flange below and accomplishing, need carry out secondary leveling to the levelness of upper flange, even the person need hang out the upper flange, leveling again, this greatly increased constructor's work load.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: in order to solve the technical problem, the utility model provides a convenient arrangement structure who goes up flange mounting for crab-bolt cage on wind turbine generator system basis.
The utility model adopts the technical proposal that: the utility model provides an arrangement structure that is used for on wind turbine generator system basis crab-bolt cage, the crab-bolt cage has two and encircles by a plurality of fixed mounting subaerial crab-bolt, and the crab-bolt between two crab-bolt rings corresponds mutually to form an anchor bolt group, has the lower flange at crab-bolt cage lower part fixed mounting, has the upper flange at crab-bolt cage upper portion fixed mounting, and the cover is equipped with the sleeve pipe on the crab-bolt between upper flange and lower flange, and the pouring of crab-bolt cage department between upper flange and lower flange has concrete material, its characterized in that: the upper part of the anchor bolt cage is fixedly provided with an upper flange through a plurality of flange mounting structures which are uniformly arranged on the anchor bolt cage, and the upper flange mounting structures are arranged between two adjacent bolt groups;
the upper flange mounting structure is provided with an upper steel plate fixedly mounted between two adjacent bolt groups, and the upper steel plate is connected with a lower steel plate mounted below the upper flange through fixing bolts. Therefore, the upper steel plate is arranged at the position of the anchor bolt ring where the flange needs to be arranged, the upper steel plate is fixedly arranged on the anchor bolt through the rigid nut, and after the integral structure is leveled in advance, the follow-up secondary leveling of the upper flange is avoided. The upper flange is fixedly arranged on the anchor bolt ring through a lower steel plate fixedly connected with the upper steel plate, the lower steel plate bears the weight of constructors on the upper flange and the upper flange, and is transmitted to the upper steel plate through a fixing bolt connected with the upper steel plate and finally transmitted to the anchor bolt. When high-strength grouting is carried out below the upper flange, after the upper flange leveling piece is installed on foundation concrete below the upper flange, high-strength grouting is carried out below the upper flange, whether the upper steel plate and the lower steel plate can be detached or not at the moment, and the upper flange leveling piece is buried in concrete body.
Be equipped with the screw thread on the crab-bolt, the upside of upper portion steel sheet is installed and is had an upper portion nut with bolt screw-thread fit, and the downside of upper portion steel sheet is installed and is had a lower part nut with bolt screw-thread fit, the upper portion steel sheet is through the upper portion nut with bolt threaded connection and lower part nut fixed mounting on adjacent two sets of bolt groups. So, upper portion steel sheet can stable installation between four crab-bolts, and the installation of upper portion steel sheet is more stable.
And a gasket is sleeved on the bolt between the lower nut and the upper flange. In this way, wear between the upper flange and the lower nut is reduced.
The lower steel plate is arranged between the two bolt groups along the radial direction of the anchor bolt ring, the fixing bolts connected with the upper steel plate are installed on the two sides of the lower steel plate in the radial direction of the bolt ring, and the fixing nuts in threaded fit with the fixing bolts are installed on the upper steel plate. Therefore, the two sides of the lower steel plate extend out of the inner side and the outer side of the upper flange respectively, the lower steel plate is fixedly arranged below the lower flange through the fixing bolts which are arranged on the two sides of the radial direction of the bolt ring and connected with the upper steel plate, and meanwhile, the mutual influence between the fixing bolts and the upper flange can be avoided.
The beneficial effects of the utility model are that: the upper flange is fixed through the upper layer steel plate and the lower layer steel plate, after concrete pouring and high-strength grouting of an anchor bolt cage below the upper flange are completed, the upper steel plate is taken out from the upper flange through dismantling upper bolts and lower bolts on anchor bolts, fixing nuts for connecting the upper steel plate and the lower steel plate are dismantled, and at the moment, when the anchor bolts are stretched, the anchor bolts are subjected to uniform tensile stress everywhere, and the anchor bolts are uniformly stretched. So, when having avoided last flange below installation nylon nut, need carry out the secondary leveling to last flange before accomplishing the grout that excels in of flange below. When fixing the upper portion steel sheet on the crab-bolt, bear the weight of flange through the lower part steel sheet with upper portion steel sheet fixed connection, make the upper flange firm, the roughness satisfies the design requirement, and the last flange weight transmission that the lower part steel sheet will bear simultaneously gives the upper portion steel sheet to finally transmit to on the crab-bolt.
