Description

Technical Field

[0001] The utility model relates to the technical field of positioning sleeves of threaded fasteners, in particular to a positioning sleeve and an assembly. Background Art

[0002] During building construction, in order to carry out the subsequent construction of additional structures such as pipeline connection and bracket installation, connecting bolts, such as expansion bolts, are set on the inner wall or top surface of the formed building. The connecting bolts are fixed by drilling holes in the formed surface, and then the pipelines and brackets and other structures are connected and fixed by the connecting bolts. However, this setting method will destroy the cast concrete structure. If the construction is not done properly, it will affect the strength and reliability of the concrete structure. The drilling process also causes strong noise and a lot of dust, making the construction environment even worse. In addition, when connecting pipelines and brackets and other structures, connecting bolts need to be set in multiple locations, that is, holes need to be drilled in multiple locations, which has the problems of high construction intensity and low construction efficiency. In addition, the existing positioning sleeves are not accurately positioned. Generally, they only include the main body of the cylindrical structure. For example, a positioning sleeve that is partially set by pre-embedding may cause the concrete to sink during the pre-embedding process, causing the sleeve to shift, affecting the final positioning accuracy.

[0003] It can be seen that the structure of the positioning sleeve in the existing technology still has room for improvement. It should be optimized to reduce damage to the concrete casting structure when installing the positioning sleeve, improve construction efficiency, and increase the positioning accuracy of the positioning sleeve to improve reliability. Therefore, it is necessary to propose a more reasonable technical solution to solve the technical problems existing in the existing technology. Utility Model Content

[0004] In order to overcome at least one of the defects mentioned above, the utility model proposes a positioning sleeve and assembly. By improving the port structure of the positioning sleeve, the positioning sleeve can be quickly connected and positioned with the installation surface while maintaining accuracy. In the subsequent use as a connecting structure for pipelines, brackets, etc., it avoids damage to the concrete casting structure, reduces the subsequent manual labor intensity, and improves construction efficiency.

[0005] In order to achieve the above-mentioned purpose, the positioning sleeve disclosed in the present utility model can adopt the following technical solutions:

[0006] A positioning sleeve includes: a sleeve for connecting to a concrete casting structure, the sleeve including a connecting section and an integrally formed fixed end, the end of the sleeve forming a circular settlement structure facing the interior of the sleeve; the fixed end is connected to the settlement structure, and the fixed end includes a fitting flange arranged along the end circumference of the settlement structure, and a plurality of fixing holes for matching the concrete casting structure.

[0007] The aforementioned positioning sleeve is used to connect and secure to a concrete cast structure. Its fixed end engages and secures the concrete surface, allowing for bolt connection and securing of pipelines and brackets. This positioning sleeve solution avoids the need for drilling holes in the cast surface later, thus preventing damage to the cast surface. It also saves manpower and improves overall construction efficiency.

[0008] Furthermore, to facilitate better connection and coordination, the present invention incorporates a sinking structure. This structure can employ a variety of feasible solutions, which are not intended to be exclusive. Here, we provide an optimization and propose one feasible option: the sinking structure includes a sinking platform connected to the sleeve, with a sinking hole formed on the sinking platform, and the inner diameter of the sinking hole is larger than the threaded hole diameter of the sleeve. When this solution is employed, the sinking structure and the connecting section are integrally formed.

[0009] Furthermore, in the present invention, the outer diameters of the sleeve, the settling platform, and the fixed end are sequentially increased. With this arrangement, the connecting section and the settling platform are both fitted into the connection hole of the concrete casting structure, while the fixed end is attached to the surface of the concrete casting structure, thereby maintaining a stable fit.

[0010] Furthermore, the structure of the fitting flange can adopt a variety of solutions, which are not limited to a single solution. Here, we optimize and propose a feasible option: the fitting flange comprises an annular integral structure, and the fixing hole is provided on the integral structure. When this solution is adopted, the fitting flange and the fixing hole form a single integral structure and are integrally formed with the connecting section, which can improve the strength of the entire positioning sleeve.

[0011] Furthermore, another feasible option for setting up the fitting flange is proposed here: the fitting flange includes a plurality of split structures distributed at intervals, and the fixing holes are provided on the split structures.

[0012] Furthermore, another feasible option for setting up the fitting flange is proposed here: the fitting flange includes a plurality of split structures distributed at intervals, and the fixing holes are arranged between the split structures.

[0013] To further enhance the stability of the positioning sleeve during pouring, a feasible optimization option is proposed: the outer wall of the connecting section is provided with several anchoring structures. In this solution, the anchoring structures can be recessed into the connecting end or protruding from the surface of the connecting section, mixing with the concrete during pouring to form a stable structure.

[0014] Furthermore, the anchoring structure can be constructed in various forms, which are not limited to a single one. Here, we optimize and propose one feasible option: the anchoring structure includes an anchoring groove. When such a solution is adopted, concrete flows into the anchoring groove during pouring and solidifies to form a locking structure for the anchoring groove.

[0015] Furthermore, the anchor groove structure can be configured in a variety of forms and is not limited to a single one. Here, we optimize and propose one feasible option: the anchor groove extends along the circumference of the outer wall of the connecting section and forms an arcuate groove or an annular groove. In this solution, multiple arcuate anchor grooves can be provided along a circumference, or the entire groove can be provided as an annular groove.

[0016] Furthermore, in order to improve the stability of the anchoring grooves and increase the number of anchoring grooves, the specific distribution method is not uniquely limited. Here, optimization is performed and one feasible option is proposed: the anchoring grooves are evenly spaced along the length extension direction of the connecting section.

[0017] Furthermore, to improve reliability during specific applications, the structure of the anchor groove is optimized and a feasible option is proposed: the anchor groove includes an anti-dropout anchoring surface extending obliquely toward the groove bottom. When this solution is adopted, the cross-section of the anchor groove is a triangular structure.

[0018] The above content discloses a positioning sleeve. The present utility model also discloses a positioning assembly, which is described in detail as follows:

[0019] A positioning assembly includes the positioning sleeve and a connecting piece as described above. The connecting piece includes a sinking structure extending into the sleeve and a mating section threadedly connected to the sleeve. A through hole is also provided on the connecting piece.

[0020] Compared with the prior art, some of the beneficial effects of the technical solution disclosed in this utility model include:

[0021] The utility model provides a positioning sleeve and a positioning assembly in the concrete casting structure for construction and connection of additional structures, which not only avoids damage to the concrete molding surface, but also improves the overall positioning accuracy and connection reliability, reduces manual labor intensity, and improves subsequent construction efficiency.
