Detailed Description
In order to enable those skilled in the art to better understand the technical solution of the present utility model, the technical solution of the present utility model is further described below with reference to the accompanying drawings and examples.
Referring to the accompanying drawings 1-5, the adjusting device for the wedge-shaped block at the bottom of the precast beam and the embedded steel plate comprises a supporting bottom plate 1, an adjusting mechanism is vertically arranged on the upper surface of the supporting bottom plate, an adjusting top plate 2 is arranged at the top end of the adjusting mechanism, and the adjusting top plate 2 is inclined in any direction compared with the horizontal plane under the driving action of the adjusting mechanism. When the adjusting device is used, the adjusting device is stably placed on the ground through the supporting bottom plate 1, the adjusting top plate 2 at the top end of the adjusting device is correspondingly contacted with the bottom surface of the precast beam by placing the wedge-shaped block or the embedded steel plate, and the adjusting device is driven to adjust through the adjusting mechanism according to the inclined included angle of the bottom surface of the wedge-shaped block or the embedded steel plate, so that the adjusting top plate 2 horizontally deflects and is in flat contact with the bottom surfaces of the wedge-shaped block or the embedded steel plate, and the bottom surface of the precast beam with the gradient is stably supported, so that the gradient bottom surface of the bridge is formed. And meanwhile, the adjusting device can be integrally placed at the top end of the pier column when being erected with the precast beam, and the inclination angle of the adjusting top plate 2 at the top end of the adjusting device is adjusted through the adjusting mechanism according to the inclination angle of the gradient of the bottom surface of the erected precast beam so as to be suitable for stably supporting the bridge with the gradient.
Specifically, as shown in fig. 1, the adjusting mechanism includes adjusting screws 11 disposed on the supporting base plate 1 at intervals along a circumferential direction and adjusting nuts 12 sleeved on the adjusting screws, an adjusting sleeve 13 contacting the adjusting nuts 12 is vertically and movably sleeved on the top of each adjusting screw 11, and the bottom surface of the adjusting top plate 2 contacts with the top end surface of the adjusting sleeve 13. During adjustment, each adjusting nut 12 is rotated, an adjusting sleeve 13 is driven in the process of moving upwards along an adjusting screw 11, an adjusting top plate 2 is driven to horizontally lift to be propped against the bottom surface of a wedge block or a pre-embedded steel plate through the adjusting sleeve 13, and then the adjusting nuts 12 at corresponding positions are adjusted according to the inclined included angle of the bottom surface of the wedge block or the pre-embedded steel plate, so that the adjusting top plate 2 is deviated and flatly attached to the bottom surface of the wedge block or the pre-embedded steel plate to be supported. Through adjusting the adjusting nut 12 in different positions, can make the adjusting roof 2 according to wedge or pre-buried steel sheet bottom surface slope contained angle with horizontal, vertical and slant deflection and realize flat laminating support, help improving the steady support to the precast beam.
In order to avoid the problem that the adjusting top plate 2 is inclined and supported and is subject to sliding deviation or falling off from the top end of the adjusting sleeve 13 due to the action of external force, as shown in fig. 2, hemispherical protrusions 13a are disposed on the top end surface of each adjusting sleeve 13, spacing posts 21 are disposed at intervals on the bottom surface of the adjusting top plate 2, and arc-shaped grooves 21a rotationally embedded in the hemispherical protrusions 13a are disposed in each spacing post 21. In the process of adjusting the corresponding adjusting nut 12, the adjusting top plate 2 is deflected according to the inclined included angle of the bottom surface of the wedge-shaped block or the embedded steel plate (shown by arrow b in fig. 5), in the process, each limiting column 21 is in rotary contact with the hemispherical protrusion 13a through the arc-shaped groove 21a to realize deflection adjustment of the adjusting top plate 2, and meanwhile, the problem that the adjusting top plate 2 and the adjusting sleeve 13 deviate or fall is effectively limited, so that the supporting stability of the adjusting device is improved.
Specifically, as shown in fig. 1, the vertical height of the hemispherical protrusion 13a is greater than the vertical depth of the arc-shaped groove 21a, so that in the contact state of the hemispherical protrusion and the arc-shaped groove, a deflection gap (shown as a in the drawing) is reserved between the ground end surface of the limiting post 21 and the top end surface of the adjusting sleeve 13, and the problem of deflection interference of the adjusting top plate 2 caused by mutual contact of the two end surfaces is avoided.
Specifically, the inner diameter of the adjusting sleeve 13 is greater than the outer diameter of the adjusting screw 11, so that the adjusting sleeve 13 can horizontally deviate from the adjusting screw 11, thereby avoiding the dislocation of the arc-shaped groove 21a and the hemispherical protrusion 13a caused by the horizontal movement of the limiting post 21 (the state shown by the arrow c in fig. 5) in the state of deflecting the adjusting top plate 2, and solving the problem that the adjusting sleeve 13 cannot stably support the adjusting top plate 2.
Since the adjusting top plate 2 drives the limit post 21 to horizontally move during the deflection process, and the adjusting sleeve 13 is further driven to horizontally deflect by the hemispherical protrusion 13a, so that the adjusting sleeve 13 and the adjusting nut 12 horizontally deflect, in order to improve the stability of the supporting of the adjusting sleeve 13 by the adjusting nut 12 in this state, as shown in fig. 1, a sliding ring plate 121 larger than the outer diameter of the adjusting sleeve 13 is provided at the top end of the adjusting nut 12. In the state that the adjusting top plate 2 deflects and the adjusting sleeve 13 horizontally deflects, the adjusting nut 12 can realize stable support of the bottom end of the adjusting sleeve 13 through the sliding ring plate 121 at the top end, so that the stability of the adjusting top plate 2 in the deflected state is improved.
The principle of the utility model is as follows: when the adjusting device is used, the adjusting device is stably placed on the ground through the supporting bottom plate 1, the adjusting top plate 2 at the top end of the adjusting device is correspondingly contacted with the wedge-shaped block or the embedded steel plate placed on the bottom surface of the precast beam, according to the inclined included angle of the bottom surface of the wedge-shaped block or the embedded steel plate, the adjusting sleeve 13 is driven by rotating each adjusting nut 12 in the upward moving process along the adjusting screw 11, the adjusting top plate 2 is driven to be horizontally lifted to be propped against the bottom surface of the wedge-shaped block or the embedded steel plate through the adjusting sleeve 13, and then the adjusting nuts 12 at corresponding positions are adjusted according to the inclined included angle of the bottom surface of the wedge-shaped block or the embedded steel plate, so that the adjusting top plate 2 is inclined and flatly attached to the bottom surface of the wedge-shaped block or the embedded steel plate to be supported. Through adjusting the adjusting nuts 12 at different positions, the adjusting top plate 2 can deflect transversely, longitudinally and obliquely according to the inclined included angle of the bottom surface of the wedge-shaped block or the embedded steel plate and realize flat-pasting and attaching support, so that stable support on the gradient bottom surface of the bridge is integrally formed.
