Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to a hollow drum glue injection tool. Background Art

[0002] Normally, carbon fiber cloth is laid on a good or polished concrete surface to increase the structural strength of the building. When the carbon fiber cloth is impregnated with glue, the carbon fiber can bond well with the concrete surface and has good tensile, shear and seismic resistance.

[0003] However, if you encounter an old building, the concrete surface is rough, the honeycomb is serious, and there are still pores or other unevenness after grinding. After applying the impregnation glue and pasting the carbon fiber cloth, there will still be hollowing. Since the carbon fiber cloth is thin, the hollowing rate is greater than 95% and can be left untreated. When it is less than 95%, the hollowing needs to be treated. The conventional method is to inject glue. When the existing glue injector injects glue, the contact with the carbon fiber cloth is not dense enough. When the glue injection port is injected, the glue injection port is limited by the bulging degree of the hollowing, which easily causes inconvenience in injection and affects construction efficiency.

[0026] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0028] The hollow drum glue injection tool is described in detail below through a specific embodiment:

[0029] Reference Figures 1 to 4 As shown, some embodiments of the present invention provide a hollow drum glue injection tool, which includes a tube body 1 and a pressing member 2.

[0030] A cavity for accommodating glue injection liquid is formed in the tube body 1, and a glue injection port 3 is provided at the end of the tube body 1. Both ends of the glue injection port 3 are through-connected and connected to the cavity. A pressing piece 2 is provided in the cavity and slidably cooperates with the inner wall of the cavity to push the glue injection liquid through the glue injection port 3. That is, by pushing the pressing piece 2, the glue injection liquid can be compressed so that the glue injection liquid is pressed out from the glue injection port 3, thereby injecting glue into the hollow drum.

[0031] Among them, the length of the cross-section of the glue injection port 3 along the first direction is greater than the length along the second direction, and the first direction is perpendicular to the second direction. Under the condition of ensuring the area of ​​the glue injection port 3 or ensuring the glue injection efficiency, the length of the glue injection port 3 along the second direction can be thinned according to actual construction needs. Even if the bulging degree of the hollow is low, the entire glue injection port 3 can pass through the carbon fiber cloth to enter the inside of the hollow. The glue injection port 3 is closely matched with the surrounding carbon fiber cloth, which can avoid causing additional damage to the surrounding carbon fiber cloth, and can also avoid leakage of the glue injection liquid, thereby ensuring the glue injection efficiency.

[0032] Of course, the thinner glue injection port 3 can also handle fine cracks, and is highly practical.

[0033] In some embodiments, the two sides of the cross section of the injection port 3 along the second direction are parallel to each other. That is, the injection liquid flowing out of the injection port 3 can be in a flat shape, so that the injection liquid can be evenly distributed in the hollow drum to avoid the problem of uneven building surface.

[0034] Reference Figure 2 As shown, the cross-section of the glue injection port 3 is parallel to each other on both sides along the first direction, that is, the cross-section of the glue injection port 3 is formed into a quadrilateral, and adjacent sides are distributed at angles. When the adjacent sides are at acute angles or right angles, they can have a certain sharpness, and thus can pierce the carbon fiber cloth for glue injection. No additional auxiliary tools are required to carry out glue injection and construction, thereby improving efficiency.

[0035] Of course, the ends of the two sides of the cross section of the glue injection port 3 along the second direction can also be formed into an arc transition, and the present disclosure does not limit this, as long as the cross section of the glue injection port 3 along the second direction is thin and can inject a flat glue liquid. Furthermore, a sharp angle can be formed in the transition section to pierce the carbon fiber cloth and perform glue injection.

[0036] In some embodiments, reference Figure 1 As shown, the tube body 1 includes a tube body 11 and a glue injection head 12 arranged at the end of the tube body 11, and the glue injection port 3 is arranged on the glue injection head 12. The end of the glue injection port 3 away from the tube body 1 is formed with a tip portion 31 to facilitate piercing the carbon fiber cloth for glue injection. That is to say, the hollow drum glue injection tool disclosed in the present invention can independently pierce the carbon fiber cloth without the need for additional auxiliary tools.

[0037] When implementing it, refer to Figure 3 and Figure 4 As shown, in the first direction, Figure 3 and Figure 4In the left-right direction, the end of the glue injection port 3 gradually extends away from the tube body 1 to form a tip portion 31. It can be understood that the tip portion 31 can be formed by gradually extending from left to right or from right to left, and the present disclosure does not limit this, as long as it has a certain sharpness and can pierce the carbon fiber cloth.

[0038] Furthermore, both ends of the end of the glue injection port 3 along the first direction are provided with a tip portion 31, and the tip portions 31 at both ends are symmetrically arranged to facilitate piercing the carbon fiber cloth. Of course, the tip portions 31 can also have other distribution modes, and can also be provided with a single, three or more, which is not limited in the present disclosure and can be specifically arranged according to actual needs.

[0039] In some embodiments, the glue injection head 12 is detachably connected to the tube body 11 to facilitate replacement of the glue injection head 12 and the glue injection port 3. Specifically, the glue injection head 12 and the tube body 11 are threaded to achieve detachable connection. Of course, the glue injection head 12 and the tube body 11 can also be detachably connected in other ways, such as snap-on connection, etc., which is not limited in the present disclosure, as long as the installation and disassembly between the glue injection head 12 and the tube body 11 can be achieved, so that the glue injection head 12 can be easily replaced.

[0040] In some embodiments, reference Figure 1 As shown, the hollow drum glue injection tool also includes a cover body 4, which is arranged at the end of the tube body 1 away from the glue injection port 3. The pressing piece 2 is arranged on the cover body 4 and movably connected to the cover body 4 so that the pressing part 22 can slide relative to the inner wall of the cavity.

[0041] In specific implementation, the pressing member 2 includes a transmission rod 21 and a pressing portion 22, the pressing portion 22 is adapted to the inner wall surface of the cavity to prevent the injection liquid from leaking back and ensure construction efficiency, the transmission rod 21 and the cover body 4 are threadedly driven, so that the pressing portion 22 is driven to slide relative to the inner wall of the cavity by rotating the transmission rod 21, so as to compress the injection liquid in the cavity and make the injection liquid flow out through the injection port 3, thereby injecting glue into the hollow drum. It can be understood that the transmission rod 21 and the cover body 4 are threadedly driven, and the sliding stroke of the transmission rod 21 relative to the inner wall of the cavity can be controlled to avoid excessive injection of glue at one time.

[0042] Of course, the pressing member 2 can also be other structures, which are not limited in the present disclosure, as long as it can slide relative to the inner wall of the cavity to push the injection liquid to flow out through the injection port 3. Specifically, the transmission rod 21 and the cover body 4 are slidably matched to push the transmission rod 21 and the pressing part 22 to slide relative to the inner wall of the cavity by directly pressing the pressing part 22.

[0043] In some embodiments, reference Figure 1As shown, the hollow glue injection tool also includes an elastic member 5, which is elastically supported between the pressing member 2 and the end of the tube body 1 close to the glue injection port 3. That is, under the elastic force of the elastic member 5, a certain resistance can be applied to the pressing member 2, which can avoid excessive glue injection at one time and ensure the construction quality.
