Description

Technical Field

[0001] The utility model belongs to the field of bridge construction equipment, and particularly relates to a pre-buried positioning device for a high-damping and plate bearing. Background Technique

[0002] During the construction process of bridge engineering, according to the requirements of construction technical specifications and on-site construction design drawings, it is necessary to ensure that the high-damping and plate bearings are uniformly stressed. At this time, the center line of the high-damping and plate bearing needs to coincide with the center line of the bearing pad stone. If the high-damping and plate bearings are unevenly stressed or not stressed, after the beam is erected, it will cause uneven pressure between the beam and the bearing, resulting in the extrusion of the tetrafluoroethylene plate, excessive shear deformation of the bearing and insufficient bearing capacity, thus causing damage to the beam structure and seriously affecting the normal service life of the bridge, posing a great potential safety hazard to the operation of the bridge after opening to traffic.

[0003] In the prior art, the commonly used construction method is: first measure whether the surface of the bearing pad stone is flat, then use a total station to set out the center line of the bearing pad stone, then calculate based on the center line as a reference to obtain the edge position of the high-damping or plate bearing, then draw a line at this position, and finally place the high-damping or plate bearing on the bearing pad stone and ensure that the edge is aligned with the marked line. However, when constructing in this way, it is more troublesome and affects the construction efficiency. Content of the Utility Model

[0004] The purpose of the utility model is to provide a pre-buried positioning device that can quickly align the center lines of the bracket-type high-damping and plate bearings with the bearing pad stone.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is a pre-buried positioning device for a high-damping and plate bearing, which includes a base plate connected to the bearing pad stone. The base plate is connected with a tray through a support arm link. The center of the tray is located on the central axis of the base plate. Upper support arms and lower top arms are respectively arranged on the base plate and the tray. When the base plate is connected to the bearing pad stone through the lower top arm, the central axis of the base plate coincides with that of the bearing pad stone. There are four upper support arms and support arms, and the four upper support arms and support arms are all distributed around the central axis of the base plate, and the support arm passes through the corresponding upper support arm. The tray is connected to the bearing to be installed through the upper support arm. When the tray moves vertically, it drives the bearing to be installed to move vertically.

[0006] Further, a horizontal pushing component is arranged on the tray. The horizontal pushing component is located on the extension line of the upper support arm, and the horizontal pushing component controls the horizontal movement of the upper support arm.

[0007] Further, the horizontal pushing component includes a flat support plate fixed on the tray. An outer baffle is fixed on the flat support plate. The outer baffle is vertically connected to the flat support plate. A threaded hole is arranged on the outer baffle, and a flat push rod is screwed into the threaded hole. The flat push rod applies a thrust to the upper support arm.

[0008] Furthermore, the upper support arm passes through the tray and a right-angle clamping member is fixed at the inner end. The extension line of the upper support arm passes through the center of the tray, and a kidney-shaped slot extending along its length is provided on the upper support arm.

[0009] Furthermore, a pulling-back plate is connected to the outer end of the upper support arm, and the pulling-back plate is connected to the outer baffle through a stretching return spring.

[0010] Furthermore, a sealing template is provided on the base plate, and the sealing template is located between two adjacent support arms. The sealing template can be flipped to a horizontal state.

[0011] Furthermore, a pressing part is provided above the sealing template. The pressing part is connected to the tray. When the tray moves downward, it drives the support and the pressing part to move downward simultaneously, so that the lower end of the pressing part abuts against the sealing template.

[0012] Furthermore, a through-hole is provided on the tray. The pressing part passes through the through-hole. A flat through-hole is provided at the upper end of the pressing part, and an elastic cord passes through the flat through-hole. Both ends of the elastic cord are fixed on the tray.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: The base plate is connected to the cushion stone, and at this time, the central axis of the base plate coincides with the central axis of the cushion stone. The tray is connected to the base plate through the support arm, and the central axes of the tray and the base plate also coincide. Therefore, as long as the central axis of the support is made to coincide with the central axis of the tray, and then the tray and the support are controlled to move vertically downward, the central axes of the support and the cushion stone can be made to coincide. Since the top plate of the support is mostly square, when each right-angle clamping member cooperates with the corner end of the corresponding top plate of the support, the central axis of the support coincides with the central axis of the tray, thus forming the coincidence of the central axes of the support and the cushion stone. The quick installation of the support can be realized through this device, and the construction efficiency is increased. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Refer to Figures 1 to 6 As shown, a pre-buried positioning device for a high-damping and plate bearing includes a base plate 1 connected to the cushion stone. The base plate 1 is an annular plate body with a circular area in the middle. The cushion stone is located within the circular area of the base plate. A lower top arm 2 is provided on the base plate 1. The lower top arm 2 penetrates the base plate 1 along the radial direction of the base plate 1. A guide rod 3 is provided below the lower top arm 2. The guide rod 3 is parallel to the lower top arm 2. A top clamp 4 is fixed at the inner end of the guide rod 3. The top clamp 4 is made of angle steel and can abut against the corner end of the cushion stone. The lower top arm 2 is screwed to the base plate 1. When the lower top arm 2 rotates, it can move axially. When the lower top arm 2 moves towards the center of the base plate 1, its inner end will push the top clamp 4 to move until the top clamp 4 abuts against the corner end of the cushion stone. There are four lower top arms 2 and four top clamps 4, and they are all distributed in a circular array around the central axis of the base plate 1, that is, the angles formed between every two adjacent lower top arms 2 are the same. At this time, the positioning of the base plate 1 is completed. Since the cushion stone is mostly square, when each top clamp 4 abuts against the corner end of the cushion stone, the center point of the cushion stone is located on the central axis of the base plate 1.

[0025] After positioning the base plate 1 and the cushion stone, the base plate 1 is connected to a tray 6 through a support arm 5. The center of the tray 6 is located on the central axis of the base plate 1. At this time, a longitudinal through-hole is provided on the tray 6, and the support arm 5 passes through the longitudinal through-hole. A spring 7 that generates a restoring force after compression can be sleeved on the support arm 5. When the bearing is not installed on the tray 6, the spring 7 is in a natural length state. After the bearing is installed on the tray 6, the tray 6 can be pressed downward, so that the tray 6 and the bearing move downward, and finally the bearing lands on the cushion stone.

[0026] Other methods can also be adopted. For example: First, place the bearing on the cushion stone. At this time, there is a load-bearing object between the bearing and the cushion stone, and the upper end of the bearing is already above the tray 6.

[0027] An upper support arm 8 is provided on the tray 6. The upper support arm 8 passes through the tray 6, and the extension line of the upper support arm 8 passes through the center of the tray. There are four upper support arms 8 and four support arms 5, and the four upper support arms 8 and support arms 5 are all distributed around the central axis of the base plate 1. The upper support arm 8 can be adjusted by horizontal movement. A right-angle clamping member is fixed at the inner end of the upper support arm 8. The right-angle clamping member includes a cushion plate 9. Two side guard plates 10 are fixed on the cushion plate 9. Both side guard plates 10 are perpendicular to the cushion plate 9, and the two side guard plates 0 are also in a perpendicular docking state. After the top of the support is located above the tray 6, by translating and adjusting the upper support arm 8, the right-angle clamping member can be made to cooperate with the corner end of the support top plate. At this time, the corner end of the support top plate is placed on the cushion plate 9. Since the support top plate is mostly square, when its four corner ends are all cooperated with the corresponding right-angle clamping members, the center line of the support at this time coincides with the center line of the base plate 1, that is, its center line also coincides with the center line of the bearing stone. Then, after removing the load on the bearing stone, slowly control the tray and the support to move downward;

[0028] When adjusting the horizontal movement of the upper support arm 8, a flat-pushing component is provided on the tray 6. The flat-pushing component is located on the extension line of the upper support arm 8. The flat-pushing component includes a flat support plate 11 fixed on the tray 6. The flat support plate 11 is in a horizontal state. An outer baffle 12 is fixed on the flat support plate 11. Threaded holes are provided on the outer baffle 12. The outer baffle 12 is perpendicularly connected to the flat support plate 11. A flat push rod 13 is screwed into the threaded hole. When the flat push rod 13 is screwed to move towards the center of the tray 6, the flat push rod 13 will apply a thrust to the upper support arm 8, achieving the purpose of controlling the horizontal movement of the upper support arm by the flat-pushing component.

[0029] It should be noted that in this embodiment, the support arm 5 passes through the corresponding upper support arm 8, that is, a hole for passing through the upper support arm 8 is provided on the tray 6. At the same time, a hole vertically penetrating the hole is also provided on the tray 6. After the upper support arm 8 passes through the hole, it is in a horizontal state. A waist-shaped slot 14 extending along its length direction is provided on the upper support arm 8. At this time, when the support arm 5 passes through the hole, it also passes through the waist-shaped slot 14, so that it will not affect the horizontal movement of the upper support arm 8;

[0030] The tray 6 is connected to the support to be installed through the upper support arm 8. When the tray 6 moves vertically, it drives the support to be installed to move vertically.

[0031] In addition, a formwork 15 is provided on the base plate 1. This formwork 15 is located between two adjacent support arms 5. The formwork 15 can be flipped to a horizontal state. A grouting hole is provided on the formwork 15. When the control tray 6 and the support move downward until they are about to contact the cushion stone, the formwork 15 can be flipped 180°. At this time, the formwork 15 is located above the base plate of the support. A pressing part 16 is provided on the tray 6. The pressing part 16 is rod-shaped and located above the formwork 15. As the tray and the support continue to move downward, the lower end of the pressing part 16 abuts against the formwork 15. At this time, the formwork can have a certain stability. Then, the pouring material is injected into the grouting hole, and the embedded installation of the support can be realized.

[0032] To make the formwork 15 have continuous stability, a through hole is provided on the tray 6. The pressing part 16 passes through the through hole. A flat through hole is provided at the upper end of the pressing part 16. An elastic cord 17 passes through the flat through hole. Both ends of the elastic cord 17 are fixed on the tray 6. When the support completely falls on the cushion stone, the lower end of the pressing part 16 abuts against the formwork 15. At this time, the elastic cord 17 is in a stretched state.

[0033] After the embedded installation of the support is completed, the upper support arm 8 can be controlled to move away from the support. Since the outer end of the upper support arm 8 is connected to a pulling plate 18, and the pulling plate 18 is connected to the outer baffle 12 through a tension return spring 19, when the flat push rod 13 no longer exerts a thrust on the outer baffle 12, under the action of the tension return spring 19, the upper support arm 8 will move away from the support. At this time, the corner end of the support top plate is separated from the right-angle clamping part, and then the whole can be lifted upward, and finally separated from the cushion stone and the support.

[0034] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claimed rights.
