Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to a positioning device for embedded parts of assembled retaining walls. Background Art

[0002] During the installation of the prefabricated retaining wall, embedded parts need to be set on the retaining wall installation foundation to facilitate the combination of the retaining wall body and the installation foundation and increase the overall stability of the prefabricated retaining wall. During the construction process, the installation foundation will be cast in advance, leaving only some embedded parts exposed on the top surface of the installation foundation. The embedded parts are usually steel bars or embedded bolts for the connection of buildings such as bus shelters and bulletin boards. In order to ensure the accurate position of the embedded parts and facilitate the connection with the ground building part, the embedded parts need to be positioned to reduce the offset of the embedded parts during the casting process, which may cause the subsequent construction to be unable to continue.

[0003] In the related art, after building a casting formwork for the installation foundation, a movable plate is usually placed on the top of the casting formwork. A plurality of through holes are opened on the movable plate for the embedded parts to pass through. One end of the embedded part is located inside the casting formwork, and the other end protrudes out of the casting formwork through the through hole. After moving the movable plate to a suitable position and casting the casting formwork, the embedded parts can be fixed during casting.

[0004] Regarding the above-mentioned related technologies, since the movable plate is movably placed on the top of the casting formwork, the spacing between adjacent steel bars is difficult to accurately adjust, and the movable plate cannot be fixed, resulting in poor positioning accuracy of the embedded parts.

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Embodiment 1

[0035] Reference Figure 1 The embodiment of the present application discloses a positioning device for embedded parts of an assembled retaining wall, comprising a mounting frame 1 fixed on the top of a casting template, a movable plate 2 slidably arranged on the mounting frame 1, and a positioning assembly 3 arranged on the movable plate 2. The mounting frame 1 is a rectangular frame, and the movable plate 2 is located inside the rectangular frame. There are multiple movable plates 2. In this embodiment, there are two movable plates 2. The movable plates 2 are slidably connected to the mounting frame 1 along a first direction. The two movable plates 2 are spaced apart along the first direction, and the first direction is the length direction of the mounting frame 1. Multiple positioning parts 13 are equally spaced along the first direction on the mounting frame 1, and the positioning assembly 3 arranged on the movable plate 2 can be docked with one of the multiple positioning parts 13, thereby realizing the positioning of the movable plate 2.

[0036] Before pouring the installation foundation of the retaining wall, the embedded parts (prefabricated steel bars) are passed through the movable plate 2, and the mounting frame 1 is fixed to the top of the casting template. The movable plate 2 is moved, and the position of the movable plate 2 can be found quickly and accurately through the docking of the positioning component 3 with the positioning portion 13, so that the embedded parts can be positioned more accurately, and the positioning component 3 also has a locking effect on the movable plate 2, thereby improving the stability of the movable plate 2, and further reducing the possibility of shaking and deflection of the embedded parts during concrete pouring, thereby further improving the precise positioning of the embedded parts.

[0037] Reference Figure 2 The positioning assembly 3 includes a mounting seat 31, an insertion rod 32 and a return spring 34. The mounting seat 31 is fixedly connected to the movable plate 2 by bolts. The insertion rod 32 is slidably connected to the mounting seat 31 along the second direction, which is the width direction of the mounting frame 1. The positioning portion 13 is a slot adapted to the insertion rod 32. The return spring 34 is sleeved on the insertion rod 32. One end of the return spring 34 is connected to the insertion rod 32, and the other end is connected to the mounting seat 31. The return spring 34 is used to push the insertion rod 32 to move toward the positioning portion 13, so that the insertion rod 32 is plugged into the slot, thereby realizing the positioning of the movable plate 2. As an alternative embodiment, the positioning portion 13 can also be a movable block that is movably set on the mounting seat and has a slot. The movable block can be adjusted in position along the first direction. By adjusting the position of the movable block, the positioning range of the positioning assembly 3 can be changed.

[0038] Since the use environment of the positioning device is dusty, in order to reduce the impact of stones, gravel and other debris embedded in the reset spring 34 on the use of the positioning device, the mounting seat 31 is hollow and is a rectangular box. Figure 2 The middle shows the state where the end cover on one side of the mounting seat 31 is opened. The return spring 34 is located inside the mounting seat 31. Both ends of the insertion rod 32 penetrate the mounting seat 31. The portion of the insertion rod 32 inside the mounting seat 31 is fixedly welded with a retaining ring 33. One end of the return spring 34 is welded to the retaining ring 33, and the other end is welded to the inner wall of the mounting seat 31. In order to facilitate pulling the insertion rod 32, a handle 35 is welded at the end of the insertion rod 32 away from the insertion hole.

[0039] During the process of moving the movable plate 2, the handle 35 is pulled to make the rod 32 slide away from the socket, and the return spring 34 is compressed. When the rod 32 moves to the vicinity of the socket at the specified position, the handle 35 is released, and the rod 32 moves close to the socket under the action of the return spring 34. At this time, the position of the movable plate 2 is fine-tuned to make the rod 32 plug into the socket, thereby realizing the positioning of the movable plate 2.

[0040] Reference Figure 1 In order to further improve the stability of the movable panel 2 when it is locked, two sets of positioning components 3 are provided on the movable panel 2, and the two sets of positioning components 3 are symmetrically arranged along the first direction. Correspondingly, the plurality of positioning parts 13 on the mounting frame 1 are symmetrically arranged along the first direction. By providing two sets of positioning components 3, both sides of the movable panel 2 are locked, thereby improving the stability of the movable panel 2.

[0041] The mounting frame 1 includes two first support members 11 arranged along a first direction and two second support members 12 arranged along a second direction. The first support member 11 is in the shape of a rectangular rod, and the second support member 12 is in the shape of a rectangular plate. The two second support members 12 are respectively located at two ends of the first support member 11 .

[0042] Reference Figure 3 In order to improve the stability of the movable plate 2 when sliding, the movable plate 2 is fixedly welded with wing plates 22 on both sides along the second direction. The wing plates 22 are rectangular plates with a width smaller than that of the movable plate 2. The two first support members 11 are provided with sliding grooves adapted to the thickness of the wing plates 22 on one side close to each other. The sliding grooves are arranged along the first direction. When the movable plate 2 slides along the first direction, the two wing plates 22 slide in the two sliding grooves, so that the movable plate 2 can slide more stably, and the sliding grooves can limit the vertical position of the movable plate 2, and cooperate with the two positioning components 3 to limit the horizontal position of the movable plate 2, thereby further improving the stability of the movable plate 2.

[0043] Since the positioning device needs to be removed after pouring, in order to save construction time, it is usually necessary to remove the movable plate 2 during the initial setting period of the concrete. In order to reduce the possibility of touching the embedded parts and causing the embedded parts to shift when the positioning device is removed, the first support member 11 and the second support member 12 are detachably connected, that is, the second support member 12 is connected to the first support member 11 by bolts. When removing the positioning device, the second support member 12 is removed from the first support member 11, and then the first support member 11 is removed from the casting template, and finally the movable plate 2 is removed from the embedded parts. Compared with the overall removal, the partial removal can greatly reduce the difficulty of removing the positioning device, thereby reducing the possibility of the embedded parts shifting when the positioning device is removed.

[0044] Embodiment 2

[0045] Reference Figure 4 Compared with the first embodiment, in the present embodiment, the movable plate 2 is removed from the mounting frame 1, and a mounting plate 5 is detachably arranged on the mounting frame 1, the mounting plate 5 is arranged along the first direction, and a plurality of limiting tubes 6 are arranged on the mounting plate 5 at equal intervals along the first direction, the limiting tubes 6 are arranged vertically, and a through hole is provided at the limiting tube 6 of the mounting plate 5, and the through hole is coaxially arranged with the limiting tube 6, so that the embedded parts can pass through the through hole from the bottom of the mounting plate 5 and pass through the limiting tube 6, thereby realizing the limiting of a single row of embedded parts. The present embodiment can be applicable to the installation of a prefabricated long row retaining wall with a single row of embedded parts.

[0046] Specifically, two reinforcing members 4 are provided on the two first supporting members 11, and the reinforcing members 4 are in the shape of an inverted U-shaped plate. The two reinforcing members 4 are respectively located at the two ends of the first supporting member 11 and between the two second supporting members 12, and are both fixedly connected to the two first supporting members 11 by bolts, and the two ends of the mounting plate 5 are respectively fixedly connected to the two reinforcing members 4 by bolts. By providing the reinforcing members 4, the mounting frame 1 can be reinforced, and the anti-deformation ability of the mounting frame 1 can be improved, and the reinforcing members 4 are provided with a plurality of prefabricated mounting holes, so as to facilitate the connection of the mounting plate 5 with the reinforcing members 4.

[0047] In order to further facilitate the installation of the mounting plate 5, a positioning assembly 3 is provided on the mounting plate 5. The positioning assembly 3 is docked with the corresponding positioning portion 13, so that the mounting plate 5 can be accurately positioned, thereby improving the positioning accuracy of the embedded part. The mounting plate 5 is provided with two positioning assemblies 3 at intervals along the first direction, so that when the mounting plate 5 is positioned and installed, the two positioning assemblies 3 pre-fix the mounting plate 5, which facilitates the connection between the mounting plate 5 and the reinforcement 4 and can improve the stability of the mounting plate 5.

[0048] Since the length of the long retaining wall is long, a single positioning device is difficult to meet the positioning requirements of multiple embedded parts. By splicing multiple mounting frames 1 along the first direction, the positioning range of the positioning device is increased. Figure 5and Figure 6 A connecting plate 7 is provided between two adjacent mounting frames 1. The connecting plate 7 is a rectangular plate. When the two mounting frames 1 are spliced, the sides of the two adjacent second support members 12 are fitted together. The connecting plate 7 is fixedly connected to the two adjacent second support members 12 by bolts, thereby realizing the splicing of the two positioning devices.

[0049] The implementation principle of the embedded part positioning device for the prefabricated retaining wall of the embodiment of the present application is as follows: by arranging a movable plate 2 or a mounting plate 5 on the mounting frame 1, the embedded parts are limited on the movable plate 2 or the mounting plate 5, and the movable plate 2 or the mounting plate 5 is positioned by the positioning component 3, which can improve the accuracy of the embedded part positioning, and the positioning component 3 can lock the movable plate 2 or the mounting plate 5 while positioning, thereby improving the stability of the movable plate 2 or the mounting plate 5, reducing the possibility of the embedded parts shaking during the pouring process, and further improving the accuracy of the positioning device for the embedded parts. Moreover, by movable matching and splicing of various components, the positioning device can adapt to embedded parts of different arrangements and quantities, thereby greatly improving the applicability of the positioning device.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
