Description

Technical Field

[0001] This utility model relates to the installation of steel mold embedded parts, and in particular to a positioning device for steel mold embedded parts. Background Technology

[0002] Steel formwork embedded parts are mainly embedded in tunnel segments, which have a certain curvature. The embedded holes on the tunnel segments are set in the radial direction. The insertion post of the steel formwork embedded part needs to be installed into the embedded hole. The traditional method is to hold the steel formwork embedded part by hand and then tap it to install the insertion post into the embedded hole. Since it is impossible to guarantee that each tap is axial during the tapping process, the steel formwork embedded part will be subjected to shear force. This will cause the steel formwork embedded part to deform occasionally or be installed in a non-proper position. Moreover, the handrail can easily be damaged during the tapping process. Therefore, a device for installing steel formwork embedded parts is needed. Utility Model Content

[0022] like Figure 1 and Figure 2 As shown, a steel mold embedded part positioning device includes an embedded part clamping assembly. The embedded part clamping assembly includes an embedded part mounting part, which has a semi-circular structure. A cover plate 4 is provided on the top of the embedded part mounting part, and a sleeve 1 is installed on the top of the cover plate 4. The sleeve 1 extends axially upward, and a push rod 2 is installed inside the sleeve 1. A threaded locking head 6 is provided on the top of the push rod 2. A threaded hole is provided on the cover plate 4, and the threaded locking head 6 is threadedly engaged with the threaded hole. An installation cavity with a larger upper cavity and a smaller lower cavity is provided on the embedded part mounting part, and a conical cavity is provided at the connection between the upper installation cavity and the lower installation cavity. In this embodiment, the steel mold... The top of the embedded part has a large cylindrical head and a tapered transition section. During installation, the steel mold embedded part is placed in the embedded part mounting section. At this time, the large cylindrical head is located in the upper mounting cavity. Then, the push rod 2 rotates, and the threaded locking head 6 rotates in the threaded hole, causing the push rod 2 to move downwards. The threaded locking head 6 then pushes the steel mold embedded part downwards. When the tapered transition section of the steel mold embedded part is in contact with the tapered cavity, the steel mold embedded part cannot move downwards, and the threaded locking head 6 cannot rotate in the threaded hole. At this point, the push rod 2 locks the steel mold embedded part, and the steel mold embedded part cannot be removed from the embedded mounting section. Figure 3 As shown, the operator only needs to align the positioning device with the steel mold embedded part with the corresponding embedded hole of the pipe segment. Since the bottom of the steel mold embedded part has an insertion post that matches the embedded hole, that is, align the insertion post with the embedded hole and then forcefully hammer it down. After the insertion post is hammered into the embedded hole, the top rod 2 is loosened, so that the threaded locking head 6 is disengaged from the top rod 2. Since the embedded part installation part is a semi-circular structure and the steel mold embedded part is a rotating structure, the entire steel mold embedded part positioning device can be removed from the side of the steel mold embedded part, and then the installation of the next steel mold embedded part can be carried out.

[0023] In this embodiment, as Figure 1 and Figure 2 The embedded part installation section includes three support legs 3. The tops of the three support legs 3 are all mounted on a cover plate 4. The circumference diameter of the inner side of the top of the support leg 3 is larger than the circumference diameter of the inner side of the bottom of the support leg 3. The cavity formed by the inner side of the top of the support leg 3 is the upper cavity, and the cavity formed by the inner side of the bottom of the support leg 3 is the lower cavity. A conical surface 7 is opened on the inner side of the support leg 3, and the cavity formed by the conical surface 7 around the circumference is a conical cavity. During installation, the steel mold embedded part is... Insert the steel mold pre-embedded part into the opening of the pre-embedded part installation section. After the threaded locking head 6 is tightened, the tapered transition section of the steel mold pre-embedded part will fit with the tapered surface 7. Then move the positioning device above the pre-embedded hole of the segment and align the insertion post with the pre-embedded hole. Then hammer the steel mold pre-embedded part into the pre-embedded hole. Then loosen the top rod 2 and then remove the entire steel mold pre-embedded part positioning device from the side of the steel mold pre-embedded part. The direction of removal is away from the direction of the opening of the steel mold pre-embedded part installation section.

[0024] In this embodiment, as Figure 1 and Figure 2 As shown, the three support legs 3 are evenly distributed on the same semicircle. Therefore, there is a window between two adjacent support legs 3 through which the steel mold embedded parts can be observed, so that the installation status of the steel mold embedded parts in the installation cavity can be preliminarily judged. Moreover, when the three support legs 3 are in contact with the tube segments during installation, the installation status of the steel mold embedded parts can be guaranteed. In this embodiment, the tube segment is an arc-shaped tube segment, and the embedded holes on the tube segment are opened in the radial direction. Therefore, the bottom surface of each support leg 3 is provided with an arc-shaped surface 10 that matches the arc of the tube segment. When the arc-shaped surface 10 is in contact with the arc surface of the corresponding surface on the tube segment, the axis of the steel mold embedded parts passes through the center of the tube segment, thereby ensuring the installation accuracy of the steel mold embedded parts.

[0025] In this embodiment, as Figure 1 and Figure 2 As shown, the top of the sleeve 1 is provided with an end cap, and a through hole is provided on the end cap. The top of the push rod 2 passes through the through hole, and a rotating handle 8 is provided at the end of the push rod 2. By rotating the handle 8, the push rod 2 can be rotated conveniently.

[0026] In this embodiment, as Figure 1 and Figure 2 As shown, a hand handle 9 is also provided on the outer side of the sleeve 1, which makes it easier for the steel mold pre-embedded part positioning device to hold it and also makes it easier to hammer the steel mold pre-embedded part into the pre-embedded hole.

[0027] In this embodiment, as Figure 1 and Figure 2 As shown, the bottom of the support leg 3 is provided with an extension extending in the radial direction. The upper surfaces of the three extensions are connected by a semi-circular connecting ring 5, and the bottom surface of the extension is an arc surface 10 that matches the curvature of the tube segment. The connection of the three extensions by the semi-circular connecting ring 5 ensures the structural strength of the embedded part installation part.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
