Description

Bridge bottom plate location drilling frock

Technical Field

The utility model relates to a bridge bottom plate appurtenance field that punches, concretely relates to bridge bottom plate location drilling frock.

Background

The steel beam outlet has two modes, and the steel plate outlet is formed by the steel plate unit outlet and the steel plate assembly welding component. The two outlet modes are respectively called first outlet and second outlet. The steel beam support bottom plate outlet hole has high precision requirement, only a rear outlet hole mode can be adopted for ensuring the outlet hole precision, a steel beam is used as an oversized component and is not easy to turn over, a covering type large sample plate is adopted for the outlet hole of the steel beam support bottom plate, a small number of special support positions are drilled by the covering type large sample plate, the processing cost is high, and the existing small sample plate is difficult to ensure that the sample plate is closely attached to the box beam bottom plate. When the box girder bottom plate support 10 is positioned and punched, an operator needs to carry out construction by raising the head, so that the precision can not meet the requirement, and meanwhile, the working efficiency is very low. Meanwhile, in order to ensure the precision, 2 to 3 persons are required for cooperative construction during construction, construction operation is very tired, and the precision completely depends on the skill and work experience of operators.

As shown in fig. 1 and 2, a conventional method for positioning a bridge floor by punching holes is to use a racket-shaped template 20, a through-type reference hole 202 is formed in a main body of the racket-shaped template 20, and a positioning plate 205 is formed in the main body of the racket-shaped template 20 on a side of a handle. A pressure sensor 204 and a through aiming hole 201 are provided on a center line b of racket-shaped template 20, and the aiming hole 201 is located on the same straight line a as two reference holes 202 on a side close to positioning plate 205, and the pressure sensor 204 is located on the same straight line c as two reference holes 202 on a side far from positioning plate 205. The racket-shaped jig 20 has a transverse aligning opening 206 formed at a position corresponding to the straight line a on both left and right edges thereof, and a longitudinal aligning opening 203 formed at an inner end side of the racket-shaped jig 20 away from the positioning plate 205, the longitudinal aligning opening 203 being located on the center line b of the racket-shaped jig 20. When aligning the line using racket-shaped pattern 20, the racket-shaped pattern 20 is pre-fixed to the lower surface of the box girder base support 10 by means of the pipe clamp with the side having the pressure sensor 204 facing upward. Then, the positioning plate 205 is abutted against the side edge of the box girder bottom plate support 10, the longitudinal alignment port 203 and the aiming hole 201 are observed, and the center line b of the racket-shaped template 20 is aligned with the transverse center line d of the box girder bottom plate support 10. The cross alignment port 206 can be used for assisting in approval and improving the alignment efficiency of the center line. In order to improve the alignment accuracy, the aiming hole 201 has a structure that an upper side orifice (the side close to the box girder bottom plate support 10) is small and a lower side orifice (a drilling side) is large, and is in a shape of an inverted circular truncated cone, and cross scale lines are carved on the periphery of the hole. When the alignment is positioned, the cross scale line on the aiming hole 201 is aligned with the datum line (transverse center line d) on the box girder bottom plate support 10, so that the alignment of the punching hole position and the datum line of the box girder bottom plate support 10 can be realized. After the alignment process is completed, the contact pressure between the racket model 20 and the box girder bottom plate support 10 can be adjusted by hanging a weight on the handle end of the racket model 20, so that the contact pressure between the racket model 20 and the box girder bottom plate support 10 is maintained at a predetermined value, and then the drilling operation can be started.
