Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a stainless steel embedded sleeve. Background Technology

[0002] Stainless steel embedded sleeves are an important component in modern building construction. With their excellent corrosion resistance, high strength and good stability, they have been widely used in many construction projects.

[0003] In the prior art, a search revealed a Chinese patent disclosing "A Stainless Steel Embedded Sleeve," application number "201821684676.7." This patent mainly includes an anti-pull-out device, a connecting rod, and an internally threaded sleeve. The anti-pull-out device is fixedly installed at the upper end of the connecting rod, and the lower end of the connecting rod is fixedly connected to the internally threaded sleeve. The ratio of the outer diameters of the anti-pull-out device, connecting rod, and internally threaded sleeve is 0.5–3:1:0.15–2.35. While this invention can bear the pull-out force through a specifically shaped anti-pull-out device, maximizing the axial pull-out force borne by the sleeve and preventing overall loosening due to rotation, the stainless steel embedded sleeve lacks an effective positioning structure. Without sufficient fixing devices, when concrete is pumped from above into the pouring area, the bottom of the sleeve is easily affected by the impact of flowing concrete and lateral forces, leading to displacement. This displacement not only causes deviations between the sleeve and its intended position but may also affect the connection accuracy of subsequent structures, thus impacting the overall construction quality. Therefore, this utility model provides a stainless steel embedded sleeve to solve the problems mentioned in the background art. Utility Model Content

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Reference Figure 1-4 This utility model discloses a stainless steel embedded sleeve, comprising a sleeve 1 with an open top and a threaded portion 8 inside for tight connection with other components, ensuring structural stability. A base 2 is fixedly connected to the bottom of the sleeve 1. The base 2 is integrally formed with the sleeve 1 and made of stainless steel, ensuring the overall structural strength and corrosion resistance. Multiple positioning rods 3 are evenly fixedly connected to the bottom of the base 2. The positioning rods 3 have a certain length and their bottom ends are all nail heads. A filling groove 6 is provided inside the base 2. Both the base 2 and the filling groove 6 are frustum structures. The inclined structure of the sleeve 1 improves stability.

[0025] During concrete pouring, sleeve 1 is positioned on the formwork foundation material, and the positioning rod 3 at the bottom is firmly embedded in the foundation material, effectively preventing sleeve 1 from shifting during the pouring process. As concrete overflows from the bottom of sleeve 1, the positioning rod 3, at a certain height, separates the bottom of sleeve 1 from the freshly poured concrete, reducing the impact of the concrete flowing within the formwork and preventing tilting or displacement due to excessive lateral force. After overflowing upwards, the surface of the concrete gradually flattens and contacts the bottom of sleeve 1. The concrete flows inside the filling groove 6 and outside the base 2, effectively dispersing the force on sleeve 1, making the force more even. This even force distribution further enhances the stability of sleeve 1 during the pouring process, providing higher stability and safety, and ensuring the construction quality of the stainless steel embedded sleeve.

[0026] The sleeve 1 has two horizontally arranged through holes 4 inside, and a vertically arranged through groove 9 inside the sleeve 1. The through holes 4 are connected to the through groove 9. The top of the through groove 9 is a blind hole structure, and the bottom of the through groove 9 is connected to the filling groove 6, which facilitates the opening of the through groove 9 inside the sleeve 1.

[0027] When concrete is poured, the through-hole 4 and through-groove 9 allow concrete material to be injected during pouring, which enhances the stability and pull-out resistance of the sleeve 1.

[0028] To ensure proper sealing of the top of the sleeve 1, a plug 5 is provided on the top of the sleeve 1. The plug 5 has a trapezoidal cross-section that fits snugly against the top of the sleeve 1. Multiple positioning pieces 7, which conform to the inner surface of the sleeve 1, are evenly and fixedly connected to the outer surface of the shorter side of the plug 5, ensuring the stability and sealing of the plug 5. Both the plug 5 and the positioning pieces 7 are flexible structures, making installation and disassembly more convenient and facilitating recycling.

[0029] Working Principle: During concrete pouring, sleeve 1 is positioned on the formwork foundation material, and the positioning rod 3 at the bottom is firmly embedded in the foundation material, effectively preventing sleeve 1 from shifting during the pouring process. As concrete is poured, it overflows upwards from the bottom of sleeve 1. The positioning rod 3, with its certain height, separates the bottom of sleeve 1 from the freshly poured concrete, reducing the impact of the concrete flowing within the formwork on sleeve 1 and preventing tilting or displacement due to excessive lateral force. After overflowing upwards, the surface of the concrete gradually flattens and contacts the bottom of sleeve 1. The concrete flows inside the filling groove 6 and outside the base 2, effectively dispersing the force on sleeve 1, making the force on sleeve 1 more uniform. This uniform force further enhances the stability of sleeve 1 during the pouring process, providing higher stability and safety, and ensuring the construction quality of the stainless steel embedded sleeve.

[0030] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
