[0037] like Figure 1 and Figure 2As shown, the first aspect of the present invention proposes a railway pad stone anchor hole positioning device, comprising: a bracket, a plurality of first pipe fittings and a plurality of second pipe fittings 12, the plurality of first pipe fittings are arranged on the bracket according to the preset anchor hole positions of the railway pad stone, one end of the first pipe fitting is connected to the bracket, and the first pipe fitting extends straight in the vertical direction; the second pipe fitting 12 is sleeved on the first pipe fitting, and the second pipe fitting 12 is arranged one-to-one with the first pipe fitting, and the end of the second pipe fitting 12 away from the bracket is in a closed state.

[0038] It is understandable that the bracket can be a metal bracket. For example, materials commonly used on construction sites such as angle steel or steel sections are made by welding. The structure of the bracket can be constructed into a frame type according to the distribution of the anchor holes of the support pad stone, such as H-type, etc. The first pipe fitting can be made of a metal straight pipe according to the diameter and length of the anchor hole, and arranged according to the layout of the anchor hole. For example, the anchor hole can be arranged at the four corners of the square. At this time, the first pipe fitting can be arranged at the four corners of the square, and each first pipe fitting is connected by the bracket. The diameter of the first pipe fitting is designed to match the diameter of the anchor hole. The second pipe fitting 12 can be used as a pre-buried pipe for the anchor hole. The pre-buried pipe protects the concrete structure of the pad stone, strengthens the strength of the pad stone, and can connect the pins of the support. The second pipe fitting 12 can be made of PVC material, which has high strength and corrosion resistance. The second pipe 12 is detachably mounted on the first pipe. The inner diameter of the second pipe 12 is equal to the outer diameter of the first pipe. The length of the second pipe 12 can be less than the length of the first pipe and slightly higher than the height of the support pad stone template. The end of the second pipe 12 away from the support can be sealed with tape or a plug to prevent concrete from entering. When the second pipe 12 is mounted on the first pipe, release oil can be applied to the first pipe to reduce the friction between the two pipes and facilitate the removal of the first pipe.

[0039] The railway pad stone anchor hole positioning device proposed in the first aspect of the present invention is to prepare the positioning device of the anchor hole in advance, arrange multiple first pipe fittings according to the design layout and size of the anchor hole, connect each first pipe fitting through a bracket, and then sleeve the second pipe fitting 12 on the first pipe fitting one by one, and seal one end of the second pipe fitting 12 to prevent it from entering the concrete. When in use, first align the positioning device with the pad stone layout point, then connect and fix the two ends of the bracket to the pad stone template, then pour concrete into the template, and finally demould the positioning device to complete the pad stone construction. The positioning device is suitable for the pad stone construction under the support of the railway bridge. The support pad stone using the positioning device can accurately locate the anchor hole, and the positioning device is simple to make, highly practical, and accurately positioned, which can ensure the quality of the pad stone construction and improve the construction efficiency.

[0040] In some embodiments of the present invention, the bracket includes a plurality of parallel transverse beams 11 and a plurality of parallel longitudinal beams 10, the transverse beams 11 and the longitudinal beams 10 are both arranged in a horizontal direction, two adjacent longitudinal beams 10 are connected by the transverse beams 11, and one end of the first pipe fitting is connected to the connection between the longitudinal beams 10 and the transverse beams 11. The crossbeam 11 and the longitudinal beam 10 refer to long strip structures, such as angle steel and the like. The crossbeam 11 and the longitudinal beam 10 can be arranged on a horizontal plane for easy processing. The length of the longitudinal beam 10 is equal to or slightly longer than the length of the cushion stone, which is convenient for connection with the cushion stone template. The crossbeam 11 connects the longitudinal beams 10 together. According to the arrangement of the anchor holes, the longitudinal beams 10 and the crossbeams 11 can be arranged in parallel, and the projections of the longitudinal beams 10 and the crossbeams 11 cover the designed positions of the anchor holes, so that the positioning structures corresponding to the anchor holes, i.e., the first pipe fitting and the second pipe fitting 12 can be fixedly connected through the longitudinal beams 10 and the crossbeams 11. The above-mentioned longitudinal beam 10 and crossbeam 11 combined bracket structure is convenient for obtaining materials at the construction site, and each crossbeam 11 and the longitudinal beam 10 bracket can be connected by welding or bolts, and the first pipe fitting can also be welded to the bracket, which is easy to assemble and has low cost.

[0041] In some embodiments of the present invention, the longitudinal beam 10 includes a first section, a second section, and a third section connected in sequence along its length direction, the first section and the third section are equal in length, the crossbeam 11 is connected to the second section, and the first section and the third section are respectively provided with a connecting portion. The longitudinal beam 10 is divided into three sections along the length direction, and the crossbeam 11 is arranged in the middle section, so that the first section and the third section can be provided with a connecting portion, which is convenient for connection with the pad stone template. Specifically, a connecting hole can be arranged on the first section and the third section, and the bolts are passed through the connecting holes and connected to the bolt holes on the template to achieve fixing the bracket to the template. A snap-on structure can also be arranged at the ends of the first section and the third section, for example, a protrusion is arranged on the longitudinal beam 10, and a groove is arranged on the template, and the two can also achieve fixing of the bracket by cooperation. The above structure can fix the positioning device on the template, so that the positioning device remains stable during construction, thereby improving the accuracy of anchor hole construction.

[0042] In some embodiments of the present invention, there are two cross beams 11, two longitudinal beams 10, four first pipes, and the cross beam 11 is connected to the connection between the first section and the second section or the connection between the third section and the second section. The length of the second section is equal to the distance between the two cross beams 11. Specifically, some specifications and models of bearing pads need to be equipped with four anchor holes. For example, the size of the bearing pad of the straight section of the standard simply supported T-beam pier with a span of 32m is 110cm wide and 160cm long, with a thickness of 35 to 50cm. Two pot-type rubber bearings are placed on each pad, and each bearing has four anchor holes, which are set at the center of the pad, and the center spacing of the anchor holes is 35cm. At this time, two longitudinal beams 10 can be set, and the length can be set to 140cm, and the length of the two cross beams 11 can be set to 50cm. The two longitudinal beams 10 are arranged in parallel, and the two ends of the cross beam 11 are respectively connected to the two longitudinal beams 10, which can be welded or connected by bolts. Two cross beams 11 can be set in the middle of the longitudinal beams 10, and the spacing between the two cross beams 11 is equal to the center spacing of the anchor holes 35cm. Correspondingly, the length of the first pipe fitting can be 40cm, the outer diameter of the first pipe fitting is 15cm, and the inner diameter of the second pipe fitting 12 is slightly larger than 15cm. The above structure can be applied to the construction of anchor holes for the pier support pad stones of the straight section of the standard simply supported T-beam with a span of 32m. It is simple to make, highly practical and accurately positioned.

[0043] In some embodiments of the present invention, the bracket further includes a positioning part and a connecting part, the positioning part is connected to the longitudinal beam 10 and / or the cross beam 11, the connecting part is arranged on the longitudinal beam 10, the positioning part is used to determine the relative position between the bracket body and the railway pad stone, and the connecting part is used to connect the railway pad stone template. The positioning part can be aligned with the pad stone measurement and layout point. Specifically, the positioning part can be connected to a positioning beam 13 on the longitudinal beam 10 or the cross beam 11, and a positioning hole 14 or a positioning mark is arranged on the positioning beam 13. The positioning hole 14 runs through the positioning beam 13. During construction, the positioning hole 14 or the positioning mark can be aligned with the pad stone measurement and layout point, so that the positioning device is placed in the correct position, and each second pipe 12 is aligned with the preset anchor hole position. The positioning part can also be other structures, and the positioning beam 13 can also be replaced with a positioning wire or a positioning belt structure. The positioning wire or the positioning belt is provided with a positioning mark. Aligning the positioning mark with the pad stone measurement and layout point can also achieve the position alignment of the positioning device.

[0044] In some embodiments of the present invention, a positioning hole 14 is provided on the positioning portion, the positioning hole 14 passes through the positioning portion, and the axial direction of the positioning hole 14 is parallel to the axial direction of the first pipe. The positioning hole 14 is processed on the positioning portion, and during construction, the positioning hole 14 can be aligned with the measured and laid-out points of the cushion stone by visual inspection, so that each first pipe is aligned with the preset anchor hole position, and positioning by hole point alignment is convenient to operate and has a good positioning effect.

[0045] In some embodiments of the present invention, the positioning part includes a positioning beam 13 arranged between two cross beams 11, and a positioning hole 14 is arranged in the positioning beam 13. The positioning beam 13 can be an angle steel structure, and the two ends of the positioning beam 13 are connected to the longitudinal beam 10 or to the two cross beams 11 respectively by welding or bolts. The positioning beam 13 sets the length and width center of the positioning device, so that the positioning hole 14 is set at the center. For example, the size of the 32m span standard simply supported T-beam straight section pier support pad stone is 110*160cm, and the distance between the middle hole and the template is 55cm and 47cm, and the first pipe fitting corresponding to each anchor hole is arranged on the periphery of the positioning hole 14. During construction, the positioning hole 14 is aligned with the measurement and layout point of the pad stone to complete the positioning of the positioning device. The above positioning structure is easy to process, low in cost, and has a good positioning effect.

[0046] In some embodiments of the present invention, the connection portion includes a plurality of connection holes provided on the longitudinal beam 10, and the connection holes are circular holes or elongated holes. The connection holes can be provided on the longitudinal beam 10 to connect with the template with nuts, and a plurality of connection holes can be provided along the length direction of the longitudinal beam 10 to accommodate templates of different specifications. In order to adapt to the construction of the pad stone of the curved section of the bridge, in the curved section of the bridge, the center line of the bridge has a certain turning radius, and there is a certain angle between the anchor hole of the curved section and the support. At this time, the connection hole of the positioning device can be set as a rectangular hole to increase the bolt connection area between the gasket and the support pad stone template hole, thereby improving the connection stability.

[0047] In some embodiments of the present invention, the bracket is a combined angle steel structure. The cross beam 11 and the longitudinal beam 10 of the bracket are both angle steels, which can be easily obtained at the construction site.
