AI Technical Summary
In existing technologies, when connecting concrete modules to the main structure, the sleeves installed in the reserved holes need to be sealed twice, which complicates the on-site procedures and increases the risk of water leakage.
The system employs telescopic sleeves, which are pre-embedded in the concrete modules. It consists of multiple sleeve units that are nested sequentially and coaxially arranged. Adjacent sleeve units can be telescopically connected to the reserved holes in the main structure, simplifying on-site installation steps and avoiding size mismatch issues.
This simplifies the on-site installation process between the concrete modules and the main structure, reducing the risk of water leakage.

Detailed Implementation
[0029] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0030] like Figure 1 As shown, this embodiment provides a concrete module, which includes a concrete module body 1 and a telescopic sleeve 2, with the telescopic sleeve 2 pre-embedded in the concrete module body 1. Because the telescopic sleeve 2 is pre-embedded in the concrete module body 1 during the concrete module manufacturing process, the step of installing the sleeve in the concrete module at the installation site is avoided. This avoids the problem of secondary sealing caused by the mismatch between the sleeve and the reserved hole size when installing the sleeve in the reserved hole of the concrete module at the installation site. It should be noted that "the telescopic sleeve 2 is pre-embedded in the concrete module body 1" means that during the reinforcement construction of the concrete module body 1, the telescopic sleeve 2 is inserted through the reinforcement of the concrete module body 1 before concrete pouring.
[0031] The telescopic sleeve 2 includes multiple sleeve units 21 that are sequentially sleeved and coaxially arranged. Two adjacent sleeve units 21 can expand and contract relative to each other so that the inner sleeve unit 21 extends out of the precast hole of the concrete module body 1 and connects to the reserved hole of the main structure 3. Only the main structure 3 needs to be poured, and there is no need to install the sleeve in the precast hole of the concrete module on site, thereby simplifying the on-site installation process of the concrete module and the main structure 3 and reducing the risk of water leakage.
[0032] In practical applications, multiple concrete modules are hoisted to the site. The main structure 3 is a steel reinforcement frame. When the concrete modules are connected to the steel reinforcement frame, the expansion sleeve 2 is stretched through the pre-drilled holes in the steel reinforcement frame before the steel reinforcement frame is poured on-site. It should be noted that when the expansion sleeve 2 is in the contracted state, its thickness does not exceed the wall thickness of the concrete modules.
[0033] As shown in Figure 2 and Figure 3 , between the two adjacent sleeve units 21, the inner wall of the sleeve unit 21 located at the outer side comprises a first smooth section 211 and an inner thread section 212 connected, and the outer wall of the sleeve unit 21 located at the inner side comprises an outer thread section 214 and a second smooth section 215 connected, the inner thread section 212 is located at the side close to the main structure 3, and the outer thread section 214 is located at the side away from the main structure 3, the two adjacent sleeve units 21 can slide relative to each other, and the inner thread section 212 of the sleeve unit 21 located at the outer side is screwed with the outer thread section 214 of the sleeve unit 21 located at the inner side, wherein the inner diameter of the first smooth section 211 of the sleeve unit 21 located at the outer side is greater than the nominal diameter of the outer thread section 214 of the sleeve unit 21 located at the inner side, and the minor diameter of the inner thread section 212 of the sleeve unit 21 located at the outer side is greater than the outer diameter of the second smooth section 215 of the sleeve unit 21 located at the inner side. As shown in Figure 6 , in this embodiment, when the two adjacent sleeve units 21 are retracted, the outer thread section 214 of the sleeve unit 21 located at the inner side rotates relative to the inner thread section 212 of the sleeve unit 21 located at the outer side, and since the inner diameter of the first smooth section 211 of the sleeve unit 21 located at the outer side is greater than the nominal diameter of the outer thread section 214 of the sleeve unit 21 located at the inner side, and the minor diameter of the inner thread section 212 of the sleeve unit 21 located at the outer side is greater than the outer diameter of the second smooth section 215 of the sleeve unit 21 located at the inner side, the outer thread section 214 slides relative to the first smooth section 211, and the inner thread section 212 slides relative to the second smooth section 215, so that the sleeve unit 21 located at the inner side can be retracted into the sleeve unit 21 located at the outer side.
[0034] As shown in Figure 4 , in order to avoid disconnection of the two adjacent sleeve units 21 when stretched, the inner wall of the sleeve unit 21 located at the outer side between the two adjacent sleeve units 21 further comprises a limiting smooth section 213 located at the end of the inner thread section 212 and away from the side of the first smooth section 211, wherein the inner diameter of the limiting smooth section 213 is less than the nominal diameter of the outer thread section 214 of the sleeve unit 21 located at the inner side. When the two adjacent sleeve units 21 are stretched, the outer thread section 214 of the sleeve unit 21 located at the inner side slides relative to the first smooth section 211 of the sleeve unit 21 located at the outer side to the inner thread section 212, and the outer thread section 214 rotates relative to the inner thread of the sleeve unit 21 located at the outer side, so that the sleeve unit 21 located at the inner side can be extended to the sleeve unit 21 located at the outer side, and since the inner diameter of the limiting smooth section 213 is less than the nominal diameter of the outer thread section 214 of the sleeve unit 21 located at the inner side, the two adjacent sleeve units 21 are prevented from being disconnected from each other.
[0035] In order to facilitate the positioning installation of the telescopic sleeve 2, the first end of the outermost sleeve unit 21 extends radially outward to form a first positioning ring 22. The second end of the innermost sleeve unit 21 extends radially outward to form a second positioning ring 23. A plurality of bolt holes are formed on the first positioning ring 22 and the second positioning ring 23. The first positioning ring 22 of the telescopic sleeve 2 is positioned by bolts between the concrete module body 1, and the second positioning ring 23 of the telescopic sleeve 2 is positioned by bolts between the main structure 3.
[0036] In the embodiment, the inner diameters of the sleeve units 21 gradually decrease from the outside to the inside, and the sleeve units 21 are in a cylindrical structure. The height of the sleeve unit 21 is 100-200mm, and the specific height is determined according to the wall thickness of the actual concrete module body 1.
[0037] The number of the telescopic sleeves 2 can be determined according to the thickness of the main structure 3, such as three as shown in FIG. 1, or six as shown in FIG. 2. Figure 5 Figure 3
