The prestressed tendon positioning bracket 100 includes a plurality of grids 1000 arranged along a first direction, and each grid 1000 includes: a plurality of cross beams 1100, the plurality of cross beams 1100 are arranged along a second direction, and the second direction is perpendicular to the first direction; a plurality of longitudinal beams 1200, the plurality of longitudinal beams 1200 are arranged along a third direction, and the third direction is perpendicular to the first direction, and the third direction is perpendicular to the second direction. The plurality of cross beams 1100 and the plurality of longitudinal beams 1200 are surrounded by a plurality of installation frames for passing the slow-setting prestressed tendons 200, which are distributed in an array. The installation frame is composed of two horizontal beams 1100 and two longitudinal beams 1200; and a plurality of positioning mechanisms 1300, and the plurality of positioning mechanisms 1300 are arranged in a one-to-one correspondence with the plurality of installation frames. In any group of corresponding positioning mechanisms 1300 and installation frames, the positioning mechanism 1300 is fixedly installed inside the installation frame, and the positioning mechanism 1300 is configured to enable the position of the slow-setting prestressed tendons 200 to be relatively fixed with respect to the installation frame; the prestressed tendon positioning bracket 100 includes a plurality of positioning channels arranged along a first direction, and the positioning channels are used to pass the slow-setting prestressed tendons 200, and each positioning channel includes a plurality of installation frames, and in any positioning channel, each installation frame is located on a different grid 1000.

[0035] To ensure stability, the cross beam 1100 and the longitudinal beam 1200 may be connected by welding.

[0036] In addition, for the convenience of subsequent description, the space enclosed by the installation frame is referred to as installation space 1001.

[0037] In addition, it is easy to understand that the prestressed tendon positioning bracket 100 can also be provided with a base 2000, such as Figure 1 and Figure 2 As shown, the multiple grids 1000 are all connected to the base 2000 , and the base 2000 supports the multiple grids 1000 .

[0038] In this embodiment, when this prestressed tendon positioning bracket 100 fixes the slow-setting prestressed tendon 200, since multiple grids 1000 are arranged along the first direction and each installation frame is provided with a positioning mechanism 1300, when the slow-setting prestressed tendon 200 is passed through the positioning channel, the distance between two adjacent grids 1000 along the first direction and the position of the positioning mechanism 1300 in different installation frames in the second and third directions can be adjusted to ensure the accuracy of the angle and position of the bending point required for the slow-setting prestressed tendon 200, thereby ensuring the stability and positioning accuracy of each slow-setting prestressed tendon 200 that is finally fixed and formed.

[0039] Specifically, the following Figures 1 to 5The complete assembly and positioning process of the prestressed tendon positioning bracket 100 is described in detail:

[0040] First, the prestressed tendon positioning bracket 100 is installed at the predetermined construction location. During the installation process, the multiple installation frames in each grid 1000 and the positioning mechanism 1300 in the installation frame need to be adjusted according to the actual working conditions (i.e., the angle and position of the bend required for different slow-setting prestressed tendons 200). Finally, it is necessary to ensure that the installed prestressed tendon positioning bracket 100 is stable and does not shake.

[0041] Then, multiple slow-setting prestressed tendons 200 are respectively installed in the positioning channels corresponding to themselves, ensuring that each slow-setting prestressed tendon 200 and the corresponding multiple positioning mechanisms 1300 are relatively stable, that is, ensuring that the slow-setting prestressed tendons 200 can be stably fixed in the installation space 1001, such as Figure 5 It is easy to understand that when the plurality of slow-setting prestressed tendons 200 are positioned, the relative relationship between the prestressed tendon positioning bracket 100 and the slow-setting prestressed tendon 200 is Figure 2 shown.

[0042] Finally, the accuracy of the final positioning can be confirmed by using instruments such as laser distance measurement. If the positioning is found to be deteriorated after measurement, it means that the position of each installation frame or each positioning mechanism 1300 was not accurately assembled when the grids 1000 were first assembled, and the assembly needs to be readjusted. If the positioning is found to be accurate after measurement, the slow-setting prestressed tendons 200 are positioned, and the subsequent construction process can continue.

[0043] refer to Figure 5 According to an optional embodiment of the present invention, the positioning mechanism 1300 includes a positioning rod 1310. In any group of corresponding positioning rods 1310 and installation frames, the positioning rods 1310 and the installation frame are arranged to form a limit frame for passing the slow-setting prestressed tendons 200, and the inner wall of the limit frame is used to be clamped with the outer wall of the slow-setting prestressed tendons 200.

[0044] For the convenience of subsequent description, the space enclosed by the limiting frame is referred to as limiting space 1002 .

[0045] In this embodiment, when the slow-setting prestressed tendon 200 is installed in the positioning channel corresponding to itself, the slow-setting prestressed tendon 200 can pass through multiple (the specific number depends on the number of grids 1000) limiting frames in sequence, and the outer wall of the slow-setting prestressed tendon 200 can be clamped with the inner wall of the limiting frame.

[0046] Therefore, this arrangement can further ensure that the slow-setting prestressed tendons 200 can be stably fixed in the multiple limiting spaces 1002, thereby further ensuring the stability and positioning accuracy of the multiple slow-setting prestressed tendons 200 that are finally fixed and formed.

[0047] Continue to refer Figure 5 According to an optional embodiment of the present invention, the positioning rod 1310 includes a first rod 1311 and a second rod 1312. In any set of corresponding positioning rods 1310 and installation frames, the first rod 1311, the second rod 1312 and the installation frame are arranged to form a limit frame.

[0048] It is easy to understand that the number of positioning rods 1310 is not specifically limited. This embodiment is only illustrated by taking the positioning rod 1310 as including the first rod 1311 and the second rod 1312. A third rod or a fourth rod can also be provided to ensure that the positioning rod 1310 can be surrounded by the installation frame to form a limit frame for clamping the slow-setting prestressed tendons 200.

[0049] Specifically, according to an optional embodiment of the present invention, the limiting frame is triangular, and the first rod 1311, the second rod 1312 and a crossbeam 1100 in the installation frame are arranged to form a triangle, such as Figure 5 shown.

[0050] In this embodiment, the positioning rod 1310 includes a first rod 1311 and a second rod 1312, and the first rod 1311, the second rod 1312 and a crossbeam 1100 in the installation frame are arranged to form a triangular limiting frame for description:

[0051] During assembly, the first end of the first rod 1311 can be fixedly connected to the upper beam 1100 in the corresponding installation frame, and the first end of the second rod 1312 can also be fixedly connected to the upper beam 1100 in the corresponding installation frame; the second end of the first rod 1311 can be fixedly connected to the lower beam 1100 in the corresponding installation frame, and the second end of the second rod 1312 can also be fixedly connected to the lower beam 1100 in the corresponding installation frame, and the second end of the first rod 1311 can be connected to the second end of the second rod 1312, so as to finally form an inverted triangle.

[0052] Continue to refer Figure 5 In addition, the limit frame can also be set as an isosceles triangle, that is, the first rod 1311 and the second rod 1312 respectively constitute the two waists of the isosceles triangle, and the vertex of the isosceles triangle faces downward; setting the limit frame as an isosceles triangle can make the positions of multiple limit frames and the slow-setting prestressed tendons 200 more uniform, which is convenient for the final positioning of the slow-setting prestressed tendons 200.

[0053] According to an optional embodiment of the present invention, in any grid 1000 , each crossbeam 1100 and each longitudinal beam 1200 can be detachably connected.

[0054] In this embodiment, the cross beam 1100 and the longitudinal beam 1200 are detachably connected. After the positioning of multiple slow-setting prestressed tendons 200 is completed, if the final positioning is detected to have a deviation through instruments such as laser ranging, it is also convenient to adjust the final position of the installation frame and the limit frame. There is no need to reassemble the entire prestressed tendon positioning bracket 100, and local fine-tuning is sufficient, thereby saving manpower and improving work efficiency.

[0055] Specifically, according to an optional embodiment of the present invention, in any group of mutually connected longitudinal beams 1200 and transverse beams 1100, the transverse beams 1100 are detachably connected to the longitudinal beams 1200 by binding.

[0056] In this embodiment, the binding method is simple to operate, low in cost and has a good connection effect; for example, during assembly, the longitudinal beam 1200 and the cross beam 1100 can be bound by binding wire to achieve a detachable connection between the longitudinal beam 1200 and the cross beam 1100.

[0057] According to an optional embodiment of the present invention, the positioning mechanism 1300 is welded to the installation frame.

[0058] In this embodiment, the positioning rod 1310 includes a first rod 1311 and a second rod 1312, and the first rod 1311, the second rod 1312 and a crossbeam 1100 in the installation frame are arranged to form a triangular limiting frame for description:

[0059] During assembly, the first end of the first rod 1311 can be welded to the upper crossbeam 1100 of the corresponding installation frame, and the first end of the second rod 1312 can be welded to the upper crossbeam 1100 of the corresponding installation frame; the second end of the first rod 1311 can be welded to the lower crossbeam 1100 of the corresponding installation frame, and the second end of the second rod 1312 can be welded to the lower crossbeam 1100 of the corresponding installation frame, and the second end of the first rod 1311 and the second end of the second rod 1312 can be welded to form an inverted triangle (i.e., a triangle with the vertex facing downwards), as shown in FIG. Figure 5 shown.

[0060] In this embodiment, the welding method can enable the positioning mechanism 1300 to be more stably installed on the installation frame, thereby further ensuring the stability of the final slow-setting prestressed tendons 200.

[0061] According to an optional embodiment of the present invention, the limiting frame has an anti-slip portion, which is used to increase the friction between the limiting frame and the slow-setting prestressed tendons 200.

[0062] In this embodiment, it is easy to understand that since the anti-slip part can increase the friction between the limit frame and the slow-setting prestressed tendons 200, the slow-setting prestressed tendons 200 can be made more stable during positioning, thereby further ensuring the precise positioning of the final multiple slow-setting prestressed tendons 200.

[0063] Figure 6 A schematic diagram of another matching relationship between the mounting frame and the slow-setting prestressed tendon in the prestressed tendon positioning bracket provided by the embodiment of the present invention is shown as follows: Figure 6 As shown, specifically, according to an optional embodiment of the present invention, the inner wall of the limit frame is provided with a rubber layer 1003, and the rubber layer 1003 constitutes an anti-slip portion.

[0064] In this embodiment, when the slow-setting prestressed tendon 200 is installed in the positioning channel corresponding to itself, the slow-setting prestressed tendon 200 can pass through multiple (the specific number depends on the number of grids 1000) limiting frames in sequence, and the outer wall of the slow-setting prestressed tendon 200 is clamped with the rubber layer 1003 on the inner wall of the limiting frame.

[0065] The rubber layer 1003 may be spread over the inner wall of the limiting frame; or, the rubber layer 1003 may be provided only on the portion of the limiting frame corresponding to the outer wall of the slow-setting prestressed tendon 200. Figure 6 As shown, Figure 6 The rubber layer 1003 is provided only on the first rod 1311 , the second rod 1312 and the upper crossbeam 1100 , which respectively correspond to the outer wall of the slow-setting prestressed tendons 200 .

[0066] According to an optional embodiment of the present invention, the cross beam 1100 and the longitudinal beam 1200 are both reinforced beams.

[0067] It is easy to understand that when the positioning mechanism 1300 includes the positioning rod 1310, the material of the positioning rod 1310 can also be steel bars.

[0068] In this embodiment, the strength of the steel bar material is relatively good, which can well ensure the stability of the finally constructed grid 1000.

[0069] It should be noted that the materials of the above-mentioned cross beam 1100, longitudinal beam 1200 and positioning rod 1310 are only for illustration. Under actual working conditions, appropriate materials can be selected according to the specific working conditions, as long as the final prestressed tendon positioning bracket 100 can stably and accurately position the slow-setting prestressed tendons 200, without any specific limitation.

[0070] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
