Description

Technical Field

[0001] The utility model relates to the field of bridge construction equipment, in particular to a bridge support pad stone anchor bolt hole positioning device. Background Art

[0002] In bridge structures, the primary function of bearing sills is to bear the bridge's load and transfer it to the piers. Bridge bearings and pier sills are installed using pre-embedded anchor holes in the pier sills. The accuracy of the anchor hole pre-embedded during sill construction is crucial to the quality and speed of subsequent bridge bearing installation and is a critical control point in bridge construction.

[0003] The existing bridge support pad stone steel bar embedded positioning control method is too simple, often using a flat steel formwork as a concrete pouring template, after the pad stone dimension line is measured and laid out, a wire is used to locate the embedded position of the anchor hole. During the subsequent pad stone steel bar installation and concrete pouring process, the position of the PVC buried pipe will inevitably be disturbed; if the anchor hole position moves or tilts, it is difficult for construction workers to detect it with the naked eye, which often causes the anchor hole to be offset or tilted after the pad stone is poured, causing problems with construction accuracy and making it difficult to install the bridge support. Utility Model Content

[0004] The purpose of this utility model is to propose a bridge support pedestal anchor hole positioning device to solve the problem that in the existing bridge support pedestal anchor hole positioning process, there are situations such as inconsistent spacing between PVC buried pipes, inaccurate positions, axis deviation or buried pipe disturbance, which causes the anchor holes to be offset or tilted after the pedestal is cast, affecting the subsequent bridge support installation.

[0005] In order to solve the above technical problems, the technical solutions adopted by the present invention are as follows:

[0006] A bridge support shim anchor bolt hole positioning device, comprising:

[0007] The first positioning fixture includes a first main beam and a second main beam arranged in parallel, and the front halves of the first main beam and the second main beam are connected by a first connecting beam; it also includes a first fixing clamp rod arranged on the first main beam and a second fixing clamp rod arranged on the second main beam, and the first fixing clamp rod and the second fixing clamp rod are both provided with fixing clamps at their ends; it also includes a connecting plate vertically arranged on the first connecting beam, the connecting plate is penetrated by a rotating screw in the same direction as the first main beam, the connecting plate is threadedly matched with the rotating screw, and a rotating clamp is provided after the rotating screw passes through the connecting plate, the rotating clamp, the fixing clamp of the first fixing clamp rod and the fixing clamp of the second fixing clamp rod cooperate with each other to clamp the PVC buried pipe; the rear half of the first main beam and the second main beam are symmetrically arranged with the front half; it also includes an internal threaded sleeve arranged between the two first connecting beams, and the two ends of the internal threaded sleeve are respectively sleeved on the two rotating screws with opposite threads; it also includes two mounting blocks sleeved on the internal threaded sleeve through bearings, and a connecting hole is provided on the top of the mounting block;

[0008] The second positioning fixture has the same structure as the first positioning fixture and is arranged side by side with the first positioning fixture;

[0009] One end of the downwardly opened U-shaped connecting rod is inserted into the connecting hole of the first positioning fixture, and the other end is inserted into the connecting hole of the second positioning fixture.

[0010] Particularly, both sides of the mounting block are fixedly connected to the first main beam and the second main beam respectively.

[0011] Particularly, a positioning mounting hole is provided at each end of the first main beam and the second main beam.

[0012] Particularly, a rotating nut is fixed at the middle of the internally threaded sleeve.

[0013] Particularly, handles are provided on the outer side walls of the middle portions of the first main beam and the second main beam.

[0014] In particular, a second connecting beam is provided between the front halves of the first main beam and the second main beam, and the first fixing clamp rod and the second fixing clamp rod are respectively provided at the connection point between the second connecting beam and the first main beam and at the connection point between the second connecting beam and the second main beam.

[0015] Furthermore, the fixed clamp rod includes an outer sleeve, in which an inner sleeve rod is movably sleeved; and also includes a compression spring, which is sleeved on the outside of the outer sleeve, with one end connected to the outer sleeve and the other end connected to the inner sleeve rod.

[0016] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0017] The utility model fixes the main beam of the first positioning fixture on the steel skeleton of the bridge support, and uses the internal threaded sleeve to drive the rotating screw to move toward the first fixed clamp rod and the second fixed clamp rod, so that the rotating clamp and the two fixed clamps clamp the installed PVC buried pipe in a triangular positioning manner, and then positions the second positioning fixture through the U-shaped connecting rod to determine the position of the PVC buried pipe to be installed, thereby achieving the purpose of positioning the anchor hole of the support pad. Since the length of the U-shaped connecting rod between the first positioning fixture and the second positioning fixture is fixed, it can also avoid the problem of inaccurate anchor hole position caused by changes in the spacing between the PVC buried pipes. Since the device is a rigid structure as a whole, it can effectively avoid the overall structural deviation caused by the installation of the pad steel bars or the pouring of concrete, thereby avoiding the position deviation of the PVC buried pipe, effectively improving the accuracy of anchor hole positioning, avoiding affecting the construction quality, and reducing the possibility of rework affecting construction efficiency.

DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention, so as to have a further understanding of the concept of the present invention, the technical problems solved, the technical features constituting the technical solutions and the technical effects brought about.

[0021] like Figure 1 As shown, a bridge support shim anchor bolt hole positioning device includes:

[0022] The first positioning fixture includes a first main beam 101 and a second main beam 102 arranged in parallel, and the front halves of the first main beam 101 and the second main beam 102 are connected by a first connecting beam 201; it also includes a first fixing clamping rod 401 arranged on the first main beam 101 and a second fixing clamping rod 402 arranged on the second main beam 102, and the ends of the first fixing clamping rod 401 and the second fixing clamping rod 402 are both provided with fixing clamps 5; it also includes a connecting plate 6 vertically arranged on the first connecting beam 201, the connecting plate 6 is penetrated by a rotating screw 7 in the same direction as the first main beam 101, and the connecting plate 6 and the rotating screw 7 are threaded The first main beam 101 and the second main beam 102 are symmetrically arranged with respect to the front half thereof; the first main beam 101 and the second main beam 102 are symmetrically arranged with respect to the rear ...

[0023] The second positioning fixture has the same structure as the first positioning fixture and is arranged side by side with the first positioning fixture;

[0024] One end of the U-shaped connecting rod 12 with an opening facing downward is inserted into the connecting hole 11 of the first positioning fixture, and the other end is inserted into the connecting hole 11 of the second positioning fixture.

[0025] When the device of the present invention is used, first, the first main beam 101 and the second main beam 102 of the first positioning fixture are fixedly installed on the steel skeleton of the bridge support, and the PVC buried pipe for locating the anchor hole is placed in the gap between the first main beam 101 and the second main beam 102, and respectively pressed against the two fixed clamps 5. According to the designed spacing between the PVC buried pipes, the position of the rotating clamp 8 is adjusted by rotating the rotating screw 7 so that the rotating clamp 8 can move toward the direction of the PVC buried pipe, and the PVC buried pipe is clamped by the two fixed clamps 5 and the rotating clamp 8 in a triangular positioning manner, thereby completing the positioning of the first group of PVC buried pipes. Then, through the U-shaped connecting rod 12, one end of the U-shaped connecting rod 12 is inserted into the connecting hole 11 of the first positioning fixture, and the position of the second positioning fixture is adjusted according to the position of the other end of the U-shaped connecting rod 12 to ensure that the other end of the U-shaped connecting rod 12 can just be inserted into the connecting hole 11 of the second positioning fixture, thereby determining the position of the second positioning fixture. After fixing the position of the second positioning fixture, the second group of PVC buried pipes are installed in the same manner. By repeating this cycle, the PVC buried pipe can be precisely positioned, and the purpose of precisely positioning the anchor bolt holes can be achieved, thus avoiding deviations that would otherwise lead to rework. During the entire process, the first main beam 101 and the second main beam 102, in addition to playing a positioning role, can also bear the upper load and transfer the weight of the entire device to the steel skeleton of the bridge support. The rotating screw 7 as a whole passes through the connecting plate 6 in a direction parallel to the first main beam 101 and the second main beam 102, which can also ensure that the moving direction of the rotating screw 7 during the entire process is also consistent with the direction of travel of the first main beam 101 and the second main beam 102, ensuring that the PVC buried pipes at both ends of the rotating screw 7 are in the same horizontal position. The main function of the U-shaped connecting rod 12 is to ensure that the distance between the first positioning fixture and the second positioning fixture is always fixed. At the same time, using two U-shaped connecting rods 12 as connecting parts can also ensure that there will be no deviation between the second positioning fixture and the first main beam 101 and the second main beam 102 of the first positioning fixture, ensuring that the two are always in a parallel state with each other. The first main beam 101 and the second main beam 102 can be positioned by fixing them with bolts, or by fixing them with tape or steel bars.

[0026] As a preferred embodiment, two sides of the mounting block 10 are fixedly connected to the first main beam 101 and the second main beam 102 respectively.

[0027] In this embodiment, the mounting block 10 is fixedly connected to the first main beam 101 and the second main beam 102 on both sides, thereby ensuring that the position of the connecting hole 11 on the mounting block 10 is fixed. At the same time, the mounting block 10 can be fixed to the first main beam 101 and the second main beam 102 to provide stable support for the upper rotating screw 7 and the middle part of the internal threaded sleeve 9, thereby preventing the threads of the internal threaded sleeve 9 and the rotating screw 7 from being stuck due to the tilting of the rotating screw 7, and also ensuring that the internal threaded sleeve 9 is always located in the middle position between the two rotating screws 7, thereby preventing the unilateral rotating screw 7 from slipping due to excessive rotation.

[0028] As a preferred embodiment, a positioning and mounting hole 13 is provided at each end of the first main beam 101 and the second main beam 102 .

[0029] In this embodiment, a structure for fixing the first main beam 101 and the second main beam 102 is provided. The positioning mounting holes 13 are used to install positioning bolts to fix the positions of the first main beam 101 and the second main beam 102 on the steel frame of the bridge support. It can also be used for cable ties or steel wires to pass through and tie the first main beam 101 and the second main beam 102 more stably to the steel frame of the bridge support.

[0030] As a preferred embodiment, a rotating nut 14 is fixed in the middle of the internally threaded sleeve 9 .

[0031] In this embodiment, by providing a rotating nut 14 in the middle of the internally threaded sleeve 9, the internally threaded sleeve 9 can be quickly rotated by a wrench, thereby optimizing the use process of the device of the utility model.

[0032] As a preferred embodiment, a handle 15 is provided on the outer side wall of the middle portion of the first main beam 101 and the second main beam 102 .

[0033] In this embodiment, by providing handles 15 on the first main beam 101 and the second main beam 102 , the handles 15 can be used as force application points to facilitate the transportation of the device of the present invention.

[0034] A second connecting beam 202 is further provided between the front halves of the first main beam 101 and the second main beam 102, and a first fixing clamp rod 401 and a second fixing clamp rod 402 are respectively provided at the connection point between the second connecting beam 202 and the first main beam 101 and at the connection point between the second connecting beam 202 and the second main beam 102.

[0035] In this embodiment, the second connecting beam 202 is used to strengthen the connection between the first main beam 101 and the second main beam 102, thereby avoiding deflection caused by excessive lateral force acting on the first main beam 101 and the second main beam 102 when the first fixed clamp rod 401 and the second fixed clamp rod 402 and the rotating clamp 8 clamp the PVC buried pipe, and ensuring that the first main beam 101 and the second main beam 102 always remain parallel.

[0036] As a preferred embodiment, the first fixed clamp rod 401 and the second fixed clamp rod 402 have the same structure, both including an outer sleeve, and an inner sleeve rod movably connected inside the outer sleeve; and also including a compression spring 16, which is sleeved on the outside of the outer sleeve, and one end is connected to the outer sleeve, and the other end is connected to the inner sleeve rod.
