Description
Technical Field
The utility model relates to an rag bolt location field, concretely relates to circular basis rag bolt positioning mechanism of major diameter.
Background
Evenly lay rag bolt's work is very complicated on the circular basis of major diameter, and the accuracy of the pre-buried position of rag bolt can directly influence the installation that upper portion equipment can be smooth, especially lay circular rag bolt to circular foundations such as the diameter is greater than 8 meters, the sleeve kiln, blast furnace, therefore rag bolt's positioning control is the key in the foundation construction, if rag bolt buries the position deviation underground too big, will influence the position accuracy of above equipment, influence overall structure's stability, and influence the quality of subsequent construction, the incident can appear even.
At present, foundation bolts are uniformly distributed on a large-diameter circular foundation, a total station is generally directly erected around the circular foundation, and then point positions of each foundation bolt are respectively released through the total station for arrangement, but generally the number of the foundation bolts of the large-diameter foundation is more than 20, so that great deviation can occur only by means of a conventional positioning method, because the positioning difficulty of each foundation bolt on a steel bar of the circular foundation is very high, the field environment is complex, the positioning is performed on the steel bar of the circular foundation, the steel bar can be frequently constructed, personnel walk, and shake easily occurs, so that the positioning accuracy is influenced, the verticality of the foundation bolt is difficult to control, the mounting accuracy of a subsequent device is influenced, and the problem of difficult mounting is easy to occur; and rag bolt's lower extreme generally can not the lug weld on the reinforcing bar frame, need set up the support frame in actual construction and come to provide the holding power for rag bolt, still need stretch out the height on basic surface to rag bolt and control, therefore the preparation precision of support frame is also higher, consequently hardly realizes rag bolt's accurate positioning through conventional operation. Therefore, it is important to find a positioning device with accurate positioning position and simple operation.
SUMMERY OF THE UTILITY MODEL
To the not enough of above-mentioned prior art, the utility model aims to solve the technical problem that: the utility model provides a circular basis rag bolt positioning mechanism of major diameter can fix a position rag bolt fast, and positioning accuracy is high and easy operation, has shortened the time limit for a project.
In order to solve the technical problem, the utility model discloses a following technical scheme:
a foundation bolt positioning mechanism for a large-diameter circular foundation is characterized in that a foundation bolt is arranged on the circular foundation and fixedly installed on the circular foundation through a positioning plate; the positioning plate is annular and is positioned above the circular foundation, the positioning plate is provided with positioning through holes corresponding to the foundation bolts and allowing corresponding foundation bolts to vertically penetrate through, the aperture of each positioning through hole is matched with the diameter of the foundation bolt, the bottom of each positioning through hole of the positioning plate is butted with a reinforcing sleeve communicated with the corresponding positioning through hole, and the central line of each positioning through hole is superposed with the central line of the corresponding reinforcing sleeve, so that the reinforcing sleeve and the corresponding positioning through holes jointly form a limiting channel of the foundation bolt; the foundation bolt is positioned in the limiting channel, the upper end of the foundation bolt protrudes out of the upper surface of the positioning plate, two fixing screws which are arranged oppositely are radially arranged on the pipe wall of the reinforcing sleeve in the same height direction, the fixing screws are spirally connected with the reinforcing sleeve and screwed into the reinforcing sleeve, and one end of each fixing screw, which is positioned in the reinforcing sleeve, is abutted against two opposite side walls of the foundation bolt to fix the foundation bolt; the bottom of the positioning plate is also provided with a plurality of connecting rods fixedly connected with the round foundation.
The utility model discloses a circular basis among rag bolt positioning mechanism is the circular basis of major diameter, especially the circular basis such as circular chimney, sleeve kiln, blast furnace that the diameter is greater than 8 meters, when using, at first according to the rag bolt's on the installation drawing distribution position, set up the corresponding positioning through-hole of every rag bolt on the locating plate in advance, in the reinforcement process of circular basis, need every rag bolt on circular basis carry out preliminary positioning, reserve the surplus position that supplies rag bolt installation and regulation with the position that every rag bolt corresponds, make things convenient for follow-up total powerstation to adjust the position of rectifying the locating plate in order to adjust rag bolt, every rag bolt all places in circular basis and the corresponding surplus position department of every rag bolt originally, the lower extreme of rag bolt is placed in the bottom of circular basis this moment; then, the foundation bolt positioning device is transferred to the upper side of the circular foundation through a crane or manually, the lower end of the connecting rod is abutted against the circular foundation, then the upper end of the foundation bolt sequentially penetrates through the reinforcing sleeve and the positioning through hole in the positioning plate, and at the moment, errors exist in the position and the height of the foundation bolt; after the levelness of the positioning plate is ensured, the height of each foundation bolt is adjusted, so that the height of the threaded section of the upper section of each foundation bolt, which protrudes out of the positioning plate, meets the subsequent installation requirements, and then the fixing screws on the two sides of the reinforcing sleeve are screwed, so that one end of each fixing screw in the reinforcing sleeve is abutted against the two opposite side walls of each foundation bolt, the foundation bolts are fixed, and the heights of the foundation bolts are adjusted; then, the total station is used for taking the point positions of two positioning through holes in the positioning plate to carry out correction positioning, the position of the positioning plate is horizontally finely adjusted, after the adjustment is finished, the accurate positioning of the positioning plate is finished, and all corresponding foundation bolts are also positioned; and finally, welding and fixing the lower end of the connecting rod and the round foundation, so that the positioning plate is fixed, and the subsequent concrete pouring construction can be carried out.
