[0028] Referring to Figure 1 , the prism 2 is fixed on the left end of the shaft body 101 by a U-shaped clamp 201, and the center point of the prism 2 is located on the extension line of the zero scale line of the scale 102, so as to cooperate with the total station instrument arranged at the construction site through the prism 2 to determine the elevation of the shaft body 101 and the geographic coordinates of the zero scale line position of the shaft body 101; wherein referring to Figure 4 , the U-shaped clamp 201 includes a U-shaped clamping body which is clamped at the left end of the shaft body 101 with the opening facing forward, two parallel fastening bolts are vertically arranged on the top side plate body of the U-shaped clamping body, so that the U-shaped clamping body is fixed on the shaft body 101 by rotating the fastening bolts to the bottom end of the fastening bolts and abutting against the top surface of the shaft body 101; correspondingly, the prism 2 is vertically arranged and fixed on the top side plate body of the U-shaped clamping body through its base.

[0029] As a preferred technical solution of this embodiment, a horizontal bubble is horizontally arranged on the top side of the prism 2, so as to ensure that the positioning shaft with the prism 2 installed is kept in a horizontal state and erected and fixed on the track beam formwork 6.

[0030] Referring to Figure 1 , the formwork positioning module is composed of a formwork positioning plate 3 and a positioning piece fixing assembly 5.

[0031] Referring to Figure 5The template positioning plate 3 comprises a vertically arranged rectangular plate body 301, a first connecting lug plate 303 is formed by extending upward at one end of the top side of the plate body 301, two positioning bolts 304 are vertically and symmetrically arranged on the lower side of the plate body 301, and a positioning nut 305 is threadedly arranged on each positioning bolt 304; a through hole is formed in the first connecting lug plate 303;

[0032] Referring to Figure 7 and Figure 8 The positioning piece fixing assembly 5 comprises a connecting column 501, a connecting shaft 502, a first limiting sleeve 503, a second limiting sleeve 504, an embedded block 505, a fixing bolt 506 and a rotating handle 507; specifically, the connecting shaft 502 is vertically fixed on one end face of the connecting column 501, the second limiting sleeve 504, the first connecting lug plate 303 of the plate body 301 and the first limiting sleeve 503 are sequentially sleeved and fixed on the connecting shaft 502; a screw hole is formed in the middle of the connecting column 501 in the radial direction, the fixing bolt 506 is horizontally arranged in the connecting column 501 in a manner perpendicular to the connecting column 501 and is threadedly connected with the connecting column 501; the embedded block 505 is a block body with a size suitable for the size of the guide groove 1011, and is threadedly sleeved on the tail end of the fixing bolt 506 through a screw hole formed in the center and abuts against the side wall of the connecting column 501; the rotating handle 507 is an L-shaped handle body, one end of which is fixed on the nut of the fixing bolt 506.

[0033] In use, the positioning piece fixing assembly 5 is slidably embedded into the guide groove 1011 through the embedded block 505, and the embedded block 505 cannot be taken out of the slot of the guide groove 1011 due to the fact that the slot width of the guide groove 1011 is smaller than the inner width; in actual application, the fixing bolt 506 is synchronously rotated by rotating the rotating handle 507, so that the length of the tail end of the fixing bolt 506 extending to the outside of the embedded block 505 is increased until it abuts against the groove bottom of the guide groove 1011; at this time, the embedded block 505 moves relatively to the slot in the guide groove 1011 and abuts against the limiting step of the slot of the guide groove 1011, so that the positioning piece fixing assembly 5 is connected and fixed on the positioning shaft 1; in this connected and fixed state, the top surface of the plate body 301 of the template positioning plate 3 abuts against the bottom surface of the positioning shaft 1.

[0034] The two template positioning modules are fixed on the two ends of the shaft body 101 through the positioning piece fixing assemblies 5, and the two plate bodies 301 of the two template positioning modules are arranged at positions corresponding to the zero scale line of the scale 102 and the guide groove width scale line, respectively, so that the two plate bodies 301 are respectively attached to the inner side surfaces of the two track beam templates 6 in the guide groove width direction; referring to Figure 9The threaded studs on the two positioning bolts 304 on each plate body 301 are press-fitted on the top surface of the plate body 301, and the nuts and the two positioning nuts 305 are abutted on both sides of the track beam formwork 6, so that the positioning device is fixed on the track groove to be poured.

[0035] Referring to Figure 1 The embedded part positioning module is composed of an embedded part positioning plate 4 and a positioning sheet fixing assembly 5.

[0036] Referring to Figure 6 The embedded part positioning plate 4 includes a vertically arranged strip-shaped plate body 401, an upwardly extended second connecting lug plate 402 is formed at one end of the top side of the plate body 401, and an extension plate is formed at the other end of the top side of the plate body 401 along the horizontal direction;

[0037] The structure of the positioning sheet fixing assembly 5 is the same as that of the positioning sheet fixing assembly in the formwork positioning module, specifically, a through hole is formed in the second connecting lug plate 402, so that the second connecting lug plate 402 is sleeved on the connecting shaft 502 of the positioning sheet fixing assembly 5 through the through hole, and is located between the first limiting sleeve 503 and the second limiting sleeve 504; Furthermore, in the same way as described above, the embedded part positioning plate 4 is fixed at the specified position of the guide through slot 1011 of the shaft body 101 through the positioning sheet fixing assembly 5; Specifically, according to the actual construction, the setting positions of the plurality of embedded part positioning modules are adapted to the positions of the embedded parts 7 and the track groove 8 preset in the construction drawing.

[0038] As a preferred technical solution of the present embodiment, the track beam construction positioning device is further provided with a laser range finder, which is used in cooperation with the prism 2 to determine whether the length and width of each track beam construction area meet the actual construction requirements.

[0039] Referring to Figure 9 The specific use principle of the track beam construction positioning device is as follows:

[0040] S1, according to the actual engineering situation of the track beam, the width of the formwork on both sides of the track beam in the width direction of the track beam construction, the width of the track groove, and the type and setting distance of the embedded parts are determined; based on this, after the formwork positioning module and the embedded part positioning module are installed on the positioning shaft 1 of the present application, the horizontal bubble of the prism 2 can be used to fix the two formwork positioning modules on the two track beam formworks 6 on both sides in the width direction; Furthermore, the embedded part positioning module arranged on the positioning shaft 1 corresponds to the preset position on the wall section;

[0041] In the track beam construction of the embodiment, the track beam includes four structural forms, namely, a structure A track beam, a structure B track beam, a structure C track beam and a structure D track beam; wherein the structure A track beam and the structure B track beam are track beams with multiple embedded structures, which include anchor plates, jacking, windproof, drainage pipes and the like; the construction focus of the two structural track beams is the accuracy of the planar position and the relative position of the embedded parts, so as to avoid related safety risks in the later use process; therefore, in the specific construction process, in addition to the formwork positioning modules arranged at both ends of the positioning shaft 1, six embedded part positioning modules are further arranged, two of which are arranged at both sides of the position of the preset track groove 8, and the other four are arranged at the positions of the four preset embedded parts 7; the structure C track beam and the structure D track beam are track beams without embedded parts, and the construction focus of the two structural track beams is the straightness of the track groove and the planar accuracy of the track embedded bolt; therefore, in the specific construction process, in addition to the formwork positioning modules arranged at both ends of the positioning shaft 1, only two embedded part positioning modules are arranged, which are arranged at both sides of the position of the preset track groove 8.

[0042] S2, when the track beam construction positioning device positioning shaft 1 is fixed in place as described above, the distance between the two track beam formworks 6 in the width direction can be directly read according to the scale line on the positioning shaft 1, and the distance between the two track beam formworks 6 in the width direction is measured by using a laser range finder; then, the planar position and elevation of the prism 2 center point are determined by using the total station instrument set on the construction site in cooperation with the prism 2; since the prism 2 is fixed at the zero scale line end of the positioning shaft 1, and the center point thereof is located on the extension line of the zero scale line, and the height difference between the prism 2 center point and the positioning shaft 1 is known, the planar position and elevation of the upper side of the two track beam formworks 6 in the width direction can be obtained through the center point of the prism 2; similarly, the planar position and elevation of each embedded part positioning module arranged on the positioning shaft 1 can also be obtained at any time, so as to check whether the embedded part positioning module for welding the embedded part meets the engineering design requirements;

[0043] S3, according to each embedded part positioning module confirmed through step S2, different embedded parts are welded and fixed, and then concrete pouring is performed to complete the track beam construction.

[0044] As described above, the track beam construction positioning device used for track beam construction can effectively provide construction efficiency, so as to reduce the process, save the construction period, reduce the rework rate, and save the labor cost; through actual engineering application, the overall planar position can be controlled within ±3mm, the relative planar position can be controlled within ±2mm, the one-time acceptance pass rate of the track beam formwork 6 reaches 100%, and the embedded part acceptance pass rate reaches more than 95%, which basically eliminates the unqualified acceptance, the need for rework and the like, and effectively guarantees the engineering quality and progress.

[0045] The above is only a preferred embodiment of the present application, and does not limit the structure of the present application in any form. Any simple modification, equivalent change and modification of the above embodiment according to the technical essence of the present application still belongs to the scope of the technical solution of the present application.
