Description

Technical Field

[0001] The present application relates to the field of prefabricated pier construction technology, and in particular to a pier reinforcement positioning device. Background Art

[0002] Prefabricated piers are gradually being widely used in bridge construction due to their fast on-site construction, low pollution to the surrounding environment, and reduced labor costs.

[0003] Prefabricated piers are produced in the prefabrication yard, transported to the construction site, and then installed on the pedestal. Currently, the connection method between the prefabricated piers and the pedestal is usually to insert the embedded steel bars embedded in the cast-in-place pedestal into the reserved holes on the prefabricated piers or the embedded sleeves for connection.

[0004] Due to the large size of bridge piers, the number of embedded steel bars required for the connection is large, usually ranging from a dozen to dozens. During the construction process, each embedded steel bar is required to be accurately inserted into the reserved holes or sleeves on the prefabricated piers. The positioning requirements for the embedded steel bars in the foundation are extremely high. Once the embedded steel bars are not positioned accurately, the prefabricated piers may not be installed. At present, it is very easy for the embedded steel bars to be inaccurately positioned during installation, resulting in the inability to install the prefabricated piers. Utility Model Content

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific preferred embodiments.

[0025] In the description of the present invention, it should be understood that the terms "left side", "right side", "upper part", "lower part", etc. indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. "First", "second", etc. do not indicate the importance of the components, and therefore cannot be understood as a limitation on the present invention. The specific dimensions used in this embodiment are only for illustrating the technical solution, and do not limit the scope of protection of the present invention.

[0026] like Figure 1 The embodiment of the present application discloses a pier column steel bar positioning device, comprising a truss 1 and two positioning plates 2, both of which are connected to the truss 1 and spaced apart, and both of which are located on the bottom surface of the truss 1, each of which is provided with a circle of positioning holes 21 for pre-embedded steel bars to pass vertically, and a bubble level 22 is provided on the truss 1. Both the positioning plates 2 and the truss 1 are provided with a plurality of lifting ears 3 for lifting with the lifting equipment.

[0027] like Figure 2 The positioning plate 2 includes a plate body 201 and a rib plate 202. The plate body 201 is provided with two parallel plates. The rib plates 202 are vertically connected between the two plate bodies 201 and are arranged at intervals along the outer contour direction of the plate body 201. The rib plates 202 are fixed to the two plate bodies 201 by welding. The plate body 201 is rectangular, and the corners are arc-shaped. The ears 3 on the positioning plate 2 are welded to the corners of the two plate bodies 201.

[0028] The positioning holes 21 are symmetrically distributed on the two plates 201 . A plurality of positioning sleeves 203 are vertically disposed between the two plates 201 and are spaced apart along the outer contour of the two plates 201 . Both ends of the positioning sleeves 203 are connected to the positioning holes 21 .

[0029] like Figure 2 , both plates 201 are provided with through slots 204, which are rectangular in shape. The two plates 201 are connected with a plurality of side plates 205 on one side facing the through slots 204, and the side plates 205 correspond to the sides of the through slots 204 one by one, that is, there are four side plates 205, which form a rectangle. The through slots 204 are used to reduce the weight of the plates 201, and at the same time, it is convenient to penetrate the working conditions of the through slot 204 area.

[0030] like Figure 1 and Figure 3 The positioning plate 2 is provided with a plurality of angle steels 6 symmetrically distributed about the truss 1. One end of the angle steel 6 is fixed to the truss 1, and the other end is provided with a long waist hole 61 parallel to the length direction of the truss 1. The positioning plate 2 is provided with a stud 62 vertically passing through the long waist hole 61, and a locking nut 63 is threadedly connected to the stud 62. There are four angle steels 6 on each positioning plate 2, and they are arranged in groups of two, distributed on both sides of the truss 1. The four angle steels 6 are arranged on the plate body 201 located above, and the two angle steels 6 in any group are arranged relative to each other about the through slot 204. The stud 62 is vertically arranged on the plate body 201 located above and passes through the long waist hole 61.

[0031] The long waist hole 61 provides a certain moving distance for the stud 62, so that the positioning plate 2 can be adjusted left and right in the length direction of the truss 1. When the positioning plate 2 needs to be fixed, the operator only needs to tighten the locking nut 63, which is convenient and quick.

[0032] like Figure 1 and Figure 4 , slide rails 4 for support are provided below both ends of the truss 1, the slide rails 4 are perpendicular to the truss 1, and slide frames 41 are provided at both ends of the truss 1. The slide frames 41 are U-shaped and open downward, and the slide frames 41 are inserted into the outside of the slide rails 4 and slidably connected with the slide rails 4. Guide ribs 411 are vertically provided on the opposite side walls of the slide frame 41, and guide grooves 42 for the guide ribs 411 to be inserted and slide are provided on the outer side walls of the slide rails 4. The guide grooves 42 penetrate along the length direction of the slide rails 4, and the slide frame 41 is threadedly connected with an adjustment screw 43 that abuts against the slide rails 4.

[0033] The operator can move the truss 1 to adjust it in a direction perpendicular to its length, thereby driving the position of the positioning plate 2 to be adjusted. When fixing the truss 1 , the adjustment screw 43 is screwed to tighten against the slide rail 4 to limit the movement of the truss 1 .

[0034] like Figure 1 and Figure 4, both ends of the slide rail 4 are provided with horizontal pads 5, each pad 5 is vertically provided with a screw sleeve 51, the screw sleeve 51 is internally threaded with an adjusting column 52, one end of the adjusting column 52 passes downward through the pad 5 and is rotatably connected with a pad 53, and the other end is upward and fixed with an adjusting nut 54, which is coaxially distributed with the adjusting column 52. The operator can adjust the distance between the pad 53 and the pad 5 by rotating each adjusting column 52, and then use the bubble level 22 to level the truss 1; the adjusting nut 54 allows the operator to clamp it with a wrench, so as to facilitate the rotation of the adjusting column 52.

[0035] Principle of the embodiment of the present application: The construction of the foundation adopts the formwork cast-in-place method. When arranging the embedded steel bars, the operator uses a crane in conjunction with the lifting ears 3 to lift the entire device onto the formwork used for the foundation formwork, and then gradually lowers it to support the pad 53 on the formwork; observe the state of the bubble level 22, and if the bubble is tilted, rotate the adjustment column 52 accordingly until the truss 1 reaches a horizontal level.

[0036] After measuring and laying out the center point of the pier, the construction workers move the truss 1 and the two positioning plates 2 to adjust the positions of the two positioning plates 2 so that the horizontal centers of the two positioning plates 2 are consistent with the center point of the pier. After adjustment, the truss 1 and the positioning plates 2 are fixed.

[0037] The embedded steel bars are passed through the positioning holes 21 and lowered into the cap to complete the positioning and arrangement of the embedded steel bars, thereby ensuring the position accuracy of each embedded steel bar and enabling the prefabricated pier column to be smoothly butted against the embedded steel bars.

[0038] The above description is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
