Description

Technical Field

[0001] This utility model relates to the field of embedded pipes in exterior walls, and in particular to a snap-fit ​​embedded sleeve structure for exterior walls. Background Technology

[0002] Pre-embedded pipes in exterior walls refer to pipes or sleeves that are pre-installed in the concrete structure during the construction phase of building exterior walls, for later installation of water supply, drainage, gas, ventilation, and electrical pipelines. The core purpose of pre-embedding pipes or sleeves is to ensure accurate positioning and reliable sealing when pipelines pass through walls, and to reduce damage to the building structure. However, in traditional building construction techniques, pre-embedded sleeves in exterior walls are mostly fixed using welding or rebar binding. During wall and column formwork assembly and concrete pouring, the sleeves are easily subject to mechanical disturbance during vibration operations, resulting in displacement, backslope, etc. Statistics show that the qualified installation rate of sleeves using this method is only 75%-85%. After formwork removal, about 20% of the sleeves exhibit axial deviations exceeding 10mm, end detachment from the wall surface, or backslope. These issues require additional costs for chiseling repairs, secondary drilling, and other remedial measures. However, repair work can easily damage the compactness of the concrete structure, exacerbating the risk of leakage. Utility Model Content

[0003] The main purpose of this utility model is to propose a snap-fit ​​type pre-embedded sleeve structure for exterior walls, which aims to solve the technical problem that the sleeve is easily displaced or reversed due to mechanical disturbance during vibration operations in the existing pre-embedded sleeve technology for exterior walls.

[0004] To achieve the above objectives, the present invention proposes a snap-fit ​​type pre-embedded sleeve structure for external walls, which includes a wall column template and a sleeve body, wherein the sleeve body is disposed between two wall column templates; it also includes a support and shielding part and a positioning part, wherein the support and shielding part and the positioning part are detachably disposed at the ends of both ends of the sleeve body.

[0005] Both wall column templates are provided with pre-embedded positioning holes, and the positioning parts at both ends of the sleeve body are respectively inserted into the pre-embedded positioning holes of the two wall column templates.

[0006] Optionally, the supporting shielding part consists of two top supports, each top support including an outer supporting layer and a shielding layer. The outer supporting layer is cylindrical and sleeved on the end of the sleeve body. The inner wall of the sleeve body abuts against the outer wall of the outer supporting layer. The shielding layer is disposed at the end of the outer supporting layer facing out of the sleeve body.

[0007] Optionally, the positioning part consists of two top cores, which are arranged on the top support along the central axis of the sleeve body.

[0008] Optionally, it also includes a first elastic support portion disposed between the two top supports;

[0009] The top core includes an anchoring section and an embedded section. The diameter of the anchoring section is smaller than the diameter of the embedded section. The shielding layer is provided with an installation through hole. The anchoring section extends outward through the installation through hole. The embedded section is located inside the top support. The end of the embedded section facing the wall column template abuts against the inner sidewall of the shielding layer, and the end away from the wall column template abuts against the end of the first elastic support.

[0010] Optionally, the first elastic support includes a first limiting tube and a first spring, wherein the first spring is installed inside the first limiting tube;

[0011] The top support also includes an inner mounting layer, which is cylindrical. The two ends of the first limiting tube are respectively sleeved in the inner mounting layers of the two top supports. The end of the embedded section extends into the first limiting tube and abuts against the end of the first spring.

[0012] Optionally, a reinforcing rib is provided between the outer support layer and the inner mounting layer.

[0013] Optionally, the top core is fixed along the central axis of the sleeve body to the side of the shielding layer facing the wall column template.

[0015] Optionally, the second elastic support includes a second limiting tube and a second spring, wherein the second spring is installed inside the second limiting tube;

[0016] The inner wall of the shielding layer is provided with a blind hole for installation, and the end of the second limiting tube is sleeved in the blind hole for installation.

[0017] Optionally, it also includes an adhesive layer disposed at the end of the sleeve body, the support shielding portion being located within the adhesive layer, and one end of the positioning portion passing through the adhesive layer.

[0018] The technical solution of this utility model has the following beneficial effects:

[0019] The sleeve body is fixed between two wall / column formwork panels by inserting the positioning part into the pre-embedded positioning hole. The supporting and shielding part provides support and shielding for the sleeve. When the wall / column formwork is closed, the positioning part is further inserted into the pre-embedded positioning hole, and the sleeve body can maintain its position by engaging with the pre-embedded positioning hole, ensuring it is in the appropriate position on the exterior wall after concrete pouring. During concrete pouring, the sleeve body can also maintain the stability of its relative position with the two wall / column formwork panels by engaging with the pre-embedded positioning hole; at the same time, the supporting and shielding part can also support the sleeve body to prevent deformation and shield it to prevent concrete from entering the sleeve body.

[0028] This utility model proposes a snap-fit ​​type pre-embedded sleeve structure for exterior walls.

[0029] Example 1

[0030] like Figures 1 to 2 As shown in Embodiment 1 of this utility model, the snap-fit ​​exterior wall pre-embedded sleeve structure includes a wall column template 600, a sleeve body 100, a support and shielding part, and a positioning part. Specifically, the sleeve body 100 is disposed between two wall column templates 600, wherein the wall column template 600 is an aluminum alloy template used to assist in the forming of concrete structures. The structure and principle of the aluminum alloy template are mature existing technologies and will not be described in detail in this embodiment. Further, the support and shielding part and the positioning part are detachably disposed at both ends of the sleeve body 100. Pre-embedded positioning holes are provided in both wall column templates 600, and the positioning parts at both ends of the sleeve body 100 are respectively inserted into the pre-embedded positioning holes of the two wall column templates 600.

[0031] In this embodiment, the sleeve body 100 is fixed between two wall column formworks 600 by inserting the positioning part into the pre-embedded positioning hole, while the supporting and shielding part provides support and shielding for the sleeve. When the wall column formwork 600 is closed, the positioning part is further inserted into the pre-embedded positioning hole, and the sleeve body 100 can maintain its position by engaging with the pre-embedded positioning hole, ensuring that it is in a suitable position on the outer wall after the concrete is poured. When pouring concrete, the sleeve body 100 can also maintain the stability of its relative position with the two wall column formworks 600 by engaging with the pre-embedded positioning hole; at the same time, the supporting and shielding part can also support the sleeve body 100 to prevent deformation of the sleeve body 100 and shield it to prevent concrete from entering the sleeve body 100. In summary, compared to welding or rebar tying fixing processes, the wall column formwork 600 assembly and concrete pouring are less likely to cause mechanical disturbance to the position of the sleeve body 100. The positioning and supporting shielding parts can effectively ensure the stability of the position, shape, and form of the sleeve body 100. Engineering practice shows that the new technology increases the sleeve body 100 installation qualification rate to over 98%, improves single-process construction efficiency by 40%, and reduces repair material waste by 30%, significantly reducing the overall construction cost while ensuring the waterproof performance of the structure.

[0032] The following is a comparative analysis table of technical indicators between traditional pre-embedded technology and snap-fit ​​external wall pre-embedded sleeve structure:

[0033]

[0034] It is worth noting that during construction, the positions of the pre-embedded positioning holes are generally determined on the wall column formwork 600 according to actual requirements. Then, a laser positioning instrument or similar device is used to mark the openings on the aluminum alloy wall column formwork 600. This ensures that the center of the opening on the inner side of the wall column formwork 600 is higher than the center of the opening on the outer side. Even if the straight line formed by the two pre-embedded positioning holes is inclined with the inner side higher than the outer side, the sleeve body 100, after being installed through the two pre-embedded positioning holes as designed above, can smoothly achieve its drainage function. Specifically, the dimensions of the pre-embedded positioning holes, the relative dimensions between the two pre-embedded positioning holes, and the specific operating steps and requirements for workers to install the sleeve body 100 are all determined by relevant regulations or actual requirements, or by a combination of both, and therefore will not be elaborated further.

[0035] like Figure 1 and 2 As shown, the aforementioned support and shielding portion consists of two top supports 200. Each top support 200 includes an outer support layer 210 and a shielding layer. The outer support layer 210 is cylindrical and sleeved on the end of the casing body 100. The inner wall of the casing body 100 abuts against the outer wall of the outer support layer 210. The shielding layer is located at the end of the outer support layer 210 facing outward from the casing body 100. The top supports 200 provide support to the casing body 100 through the outer support layer 210 and shield the casing body 100 through the shielding layer. Further, the positioning portion consists of two top cores 500, which are positioned on the top supports 200 along the central axis of the casing body 100. During construction, the two top cores 500 are respectively inserted into two pre-embedded positioning holes, thereby engaging with the pre-embedded positioning holes and ensuring the stability of the casing body 100's position.

[0036] In this embodiment, a first elastic support is provided inside the sleeve body 100, which is located between two top supports 200. The top core 500 includes an anchoring section 510 and an embedded section 520. The diameter of the anchoring section 510 is smaller than the diameter of the embedded section 520. An installation through hole is provided on the shielding layer. The anchoring section 510 extends outward through the installation through hole. The embedded section 520 is located inside the top support 200. The end of the embedded section 520 facing the wall column template 600 abuts against the inner sidewall of the shielding layer, and the end away from the wall column template 600 abuts against the end of the first elastic support. Specifically, the first elastic support includes a first limiting tube 300 and a first spring 400, with the first spring 400 installed inside the first limiting tube 300. The aforementioned top support 200 also includes an inner mounting layer 220, which is cylindrical. Both ends of the first limiting tube 300 are respectively fitted into the inner mounting layers 220 of the two top supports 200, and the end of the embedded section 520 extends into the first limiting tube 300 and abuts against the end of the first spring 400. Furthermore, a reinforcing rib is provided between the outer support layer 210 and the inner mounting layer 220.

[0037] In this embodiment, a sealing layer is provided at both ends of the casing body 100. The aforementioned top support 200 is located within the sealing layer, and one end of the top core 500 passes through the sealing layer. The sealing layer can cover the gap between the casing body 100 and the top support 200, further preventing concrete from entering the casing body 100, and also allowing the casing body 100, the top support 200, and the top core 500 to form a stable whole. Specifically, the sealing layer can be adhesive tape wrapped around the casing body 100 and the top support 200.

[0038] Before installing the sleeve body 100 onto the wall column formwork 600, one of the top supports 200 and the top core 500 needs to be placed at one end of the sleeve body 100, and then the first elastic support part needs to be installed inside the sleeve body 100. Then, the other top support 200 and the top core 500 need to be placed at the other end of the sleeve body 100. During installation, the first limiting tube 300 needs to be fitted inside the inner mounting layer 220, and the inner section 520 of the top core 500 needs to extend into the first limiting tube 300 and abut against the end of the first spring 400. This allows the first spring 400 to support the top support 200 through the inner sections 520 of the two top cores 500, ensuring that the top support 200 stably performs its function on the sleeve body 100. After completing the above operations, tape is then wrapped around the sleeve body 100 and the top support 200 to form a sealant layer. This allows the sleeve body 100, top support 200, and top core 500 to form a stable whole, so that workers can install the snap-on external wall pre-embedded sleeve structure between two wall column formworks 600.

[0039] During construction, the snap-fit ​​exterior wall embedded sleeve structure is fixed between two wall column formworks 600 by inserting the top core 500 into the pre-embedded positioning hole. Then, the wall column formwork 600 is closed and concrete is poured. After the concrete solidifies, the formwork is removed. Because the top core 500 on the inner side of the exterior wall is inclined upwards, the inner wall column formwork 600 needs to be removed from the bottom outwards; conversely, the wall column formwork 600 on the outer side of the exterior wall should be removed from the top outwards. After removing the two wall column formworks 600, the residual slurry at the end of the sleeve needs to be cleaned and the sealant layer removed. Then, the anchoring section 510 of the top core 500 is pressed into the top support 200, so that the anchoring section 510 abuts against the inner wall of the shielding layer, thereby compressing the first spring 400 and pushing the top support 200 outwards, allowing workers to retrieve the two top supports 200, the two top cores 500, and the first elastic support for the next construction section.

[0040] Example 2

[0041] The difference between this embodiment and Embodiment 1 is that the top core is fixed along the central axis of the sleeve body to the side of the shielding layer facing the wall column template. Furthermore, a second elastic support is provided within the sleeve body, positioned between the two top supports, with both ends of the second elastic support abutting against the inner sidewalls of the shielding layers of the two top supports. Specifically, the second elastic support includes a second limiting tube and a second spring, with the second spring installed within the second limiting tube; the inner sidewall of the shielding layer has a blind mounting hole, and the end of the second limiting tube is fitted into the blind mounting hole. Similarly, both ends of the second elastic support can support the top supports with the two shielding layers respectively, ensuring that the top supports stably perform their function on the sleeve body.

All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
