[0034] Please refer to Figure 1 This embodiment provides a direct head device with an ear, used in conjunction with a template, including:
[0035] Column 100, flange 200, multiple connecting parts 300, and multiple mating parts 400;
[0036] The column 100 is a hollow cylindrical structure; the flange 200 is located at the bottom of the column 100; along the circumferential direction of the flange 200, the connecting part 300 and the mating part 400 are both located on the peripheral wall of the flange 200, and the mating part 400 is located between two adjacent connecting parts 300.
[0037] The connecting part 300 is provided with a through connecting hole 301, which is used for the first fastener to pass through and connect; the first fastener can fix the flange 200 to the template.
[0038] The mating part 400 is provided with a through mating hole 401. The peripheral wall of the mating hole 401 is provided with multiple limiting protrusions 410. Adjacent limiting protrusions 410 surround to form a limiting groove 411. The limiting groove 411 is used by a second fastener to connect the mating part 400 to the template or the ribs on the template.
[0039] The connecting portion 300 of the ear direct head device is provided with a through connecting through hole 301 for the first fastener to pass through and connect; the first fastener can be used to fix the flange plate 200 to the formwork. Optionally, the first fastener is a bolt, and the formwork is provided with a threaded hole or a through hole of the same size; the first fastener is matched with the threaded hole of the formwork, so that the device can be fastened to the formwork; because the threaded hole or the through hole of the same size has a small diameter, it will not affect the quality of the formed concrete; compared with the prior art which needs to open a large-diameter through hole in the embedded part (similar to the column body 100 of the present scheme), thereby affecting the quality of the formed concrete, the structure of the present scheme is simple, easy to assemble and disassemble, can be reused, and has no effect on the forming quality. Optionally, the second fastener is a hoop wire, and the second fastener can stably connect the column body 100 to the surrounding reinforcement cage, thereby further ensuring the stability of the position between the ear direct head device and the formwork.
[0040] Please continue to refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 to understand more structural details of the ear direct head device. Optionally, the column body 100, the flange plate 200, the plurality of connecting portions 300 and the plurality of matching portions 400 are all made of PVC material, and further, the entire ear direct head device is made of PVC material. Such a setting mode makes the device itself have the advantages of high structural strength, good stability, and easy cleaning. The connecting through hole 301 and the matching through hole 401 are both circular through holes. The column body 100 is a hollow cylindrical structure.
[0041] As can be seen from the drawings, in the optional embodiment, the number of the connecting portion 300 and the matching portion 400 is the same; and along the circumferential direction of the flange plate 200, the matching portion 400 is located at the intermediate position of the adjacent two connecting portions 300. In this way, the connecting portion 300 and the matching portion 400 can be uniformly stressed.
[0042] In the optional embodiment, the plurality of connecting portions 300 are uniformly distributed on the peripheral wall of the flange plate 200. That is, the connecting portion 300 and the matching portion 400 are both uniformly distributed on the peripheral wall, thereby ensuring the stability of the structure and the uniform stress of the main column body 100.
[0043] In the optional embodiment, the diameter of the matching through hole 401 is greater than the diameter of the connecting through hole 301. Such an arrangement can ensure that the gap between the limiting protrusions 410 is appropriate to meet the clamping of the hoop wire.
[0044] In an optional embodiment, the outer walls of the connecting portion 300 and the fitting portion 400 are circular arc-shaped. In an optional embodiment, the diameters of the outer walls of the connecting portion 300 and the fitting portion 400 are the same. Such an arrangement facilitates the processing and manufacturing of the connecting portion 300 and the fitting portion 400, and does not increase the wall thickness of the column 100, thereby reducing the volume and weight of the entire ear-equipped direct head device.
[0045] In an optional embodiment, the limiting protrusions 410 are triangular tooth-shaped structures. In an optional embodiment, the end of the limiting protrusion 410 away from the fitting through hole 401 has an arc-shaped transition portion 412. This allows the hoop wire to be more easily clamped into the limiting recess 411.
[0046] The limiting protrusion 410 has a root portion close to the peripheral wall of the fitting through hole 401, and the root portions of adjacent limiting protrusions 410 have gaps therebetween. This ensures that the hoop wire can be stably clamped into the limiting recess 411.
[0047] In an optional embodiment, a cover 500 is further included, the top of the column 100 has a stepped ring groove 101, the cover 500 is arranged on the stepped ring groove 101, and the top of the cover 500 is flush with the top of the column 100, and the peripheral wall of the cover 500 abuts against the inner peripheral wall of the stepped ring groove 101. The cover 500 can close the top opening of the column 100 when required by construction, and ensures the flatness of the top of the column 100.
[0048] In an optional embodiment, the bottom of the cover 500 is provided with a positioning column 510, and the bottom wall of the stepped ring groove 101 is provided with a positioning counterbore 110, which can be clamped in the positioning counterbore 110. This can ensure the stability of the position between the cover 500 and the column 100.
[0049] In summary, the ear-equipped direct head device provided in the embodiments of the present application has at least the following advantages:
[0050] The PVC ear-equipped direct embedding technology can first avoid opening holes, does not damage the formwork, improves the turnover rate of the formwork, greatly saves costs, and reduces the labor cost expenditure caused by opening holes. Second, the ear-equipped embedded part is cheap, does not need to be lengthened, and can reduce the cost waste caused by too many and too long embedded parts. Finally, the ear-equipped direct embedding technology can reduce the rework of general quality accidents caused by opening holes.
[0051] The above merely describes specific embodiments of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed in the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
