Description

Technical Field

[0001] This utility model relates to the field of anti-seepage and anti-crack sleeve technology, specifically an anti-seepage and anti-crack sleeve device for heating pipelines passing through floor slabs. Background Technology

[0002] In building heating systems, heating pipes penetrating floor slabs are a common and critical point. Due to the significant difference in the linear expansion coefficients between the pipe material and the concrete floor slab, coupled with thermal expansion and contraction caused by temperature changes in the medium during pipe operation, vibration, and the drying shrinkage deformation of the concrete itself, stress concentration easily occurs in this area. This leads to circumferential cracks at the interface between the pipe sleeve and the concrete or in the pipe structure itself. These cracks become direct channels for water leakage, not only affecting the building's functionality but also potentially corroding the pipes, damaging the building structure, and posing fire safety hazards. Traditional pipe penetration sleeve devices often use single-layer water-stop rings or simple sealing fillers. These structures have limited anti-leakage effectiveness, especially when dealing with dynamic loads such as long-term temperature difference cycles, structural settlement, and pipe vibration. They are prone to failure due to aging of the sealing material, deformation of the water-stop ring, or cracking at the connection. Utility Model Content

[0003] The purpose of this utility model is to provide a seepage-proof and crack-proof sleeve device for heating pipes passing through floor slabs, so as to solve the problem mentioned in the background art that traditional pipe sleeve devices for passing through floor slabs mostly use single-layer water-stop rings or simple sealing fillers. Such structures have limited seepage prevention effect, especially when dealing with dynamic loads such as long-term temperature difference cycles, structural settlement and pipe vibration, they are prone to failure due to aging of sealing materials, deformation of water-stop rings or cracking of connections.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a seepage-proof and crack-proof sleeve device for heating pipes penetrating floor slabs, comprising:

[0005] No. 1 sleeve;

[0006] The No. 1 water-stop ring is set on the outside of the No. 1 sleeve, and two outer annular grooves are symmetrically opened on the outside of the No. 1 water-stop ring.

[0007] There are two No. 1 connecting rings, which are symmetrically fixed to the outside of the No. 1 sleeve.

[0008] The second sleeve is installed at both ends of the first sleeve. A bottom connecting cover is provided on the outside of the second sleeve, and a bottom limiting groove is provided at the bottom of the bottom connecting cover to cooperate with the first connecting ring.

[0009] The No. 2 water-stop ring is symmetrically fixed to the outside of the No. 1 sleeve;

[0010] A bottom sealing ring is fixed to both ends of the first sleeve, and an annular sealing groove that mates with the bottom sealing ring is opened at one end of the second sleeve.

The first water-stop ring and its outer annular groove are tightly bonded to the concrete floor slab, forming a solid first layer of seepage prevention and anchoring. Second water-stop rings are symmetrically positioned near the upper and lower surfaces of the floor slab, forming a second line of defense. Furthermore, a mechanical seal is achieved at the end face of the sleeve connection through a precise fit between the bottom sealing ring and the annular sealing groove.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 5 This utility model provides a technical solution: a seepage-proof and crack-proof sleeve device for heating pipes penetrating floor slabs, comprising: a first sleeve 1; a first water-stop ring 2 fixedly connected to the outside of the first sleeve 1, with two symmetrically formed outer annular grooves 3 on the outside of the first water-stop ring 2; two first connecting rings 6, symmetrically fixedly connected to the outside of the first sleeve 1; a second sleeve 8 installed at both ends of the first sleeve 1, with a bottom connecting cover 10 fixedly connected to the outside of the second sleeve 8, and a bottom limiting groove 16 at the bottom of the bottom connecting cover 10 that cooperates with the first connecting ring 6; a second water-stop ring 5 symmetrically fixedly connected to the outside of the first sleeve 1; a bottom sealing ring 14 fixedly connected to both ends of the first sleeve 1, and an annular sealing groove 15 that cooperates with the bottom sealing ring 14 at one end of the second sleeve 8.

[0025] It should be noted that in this embodiment, when the heating pipe needs to pass through the building floor slab, the device is first pre-embedded in the reserved hole in the floor slab. The first sleeve 1 serves as the core penetrating component, and the first water-stop ring 2, which is fixed to its outer side, is embedded in the floor slab concrete. The outer annular groove 3 on the outer side of the water-stop ring increases the contact area and interlocking force with the concrete, forming the first physical water-blocking and mechanical anchoring barrier. The inner reinforcing support ring 4 inside the water-stop ring ensures that it maintains its shape integrity during concrete construction and curing, and does not undergo crushing deformation, thereby ensuring the reliability of this seal. Near the upper and lower surfaces of the floor slab, the second water-stop ring 5 is symmetrically fixed to the first sleeve 1. On sleeve 1, its top and bottom are reinforced with the sleeve body by multiple reinforcing members 17, significantly improving tensile and peel strength. These two water-stop rings, combined with the concrete, form a double defense against leakage along the outer wall of the sleeve. They can effectively adapt to and resist uneven stress caused by the difference in thermal expansion coefficients between the floor slab and pipe materials, pipe vibration during operation, and the shrinkage of the concrete itself, preventing stress concentration from causing circumferential cracks at the interface between the sleeve and the concrete, thus fundamentally eliminating the water seepage path. At both ends of the sleeve, extension and sealing are achieved through a detachable connection structure. Sleeve 8 is connected to the outer bottom connecting cover 10 and the second connecting ring 9. The No. 1 connecting ring 6 on the outside of the No. 1 sleeve 1 is aligned with the No. 1 connecting ring 6. The bottom limiting groove 16 and the No. 1 connecting ring 6 cooperate to achieve rapid initial positioning. Multiple fixing screws 11 pre-fixed on the No. 2 connection structure pass through the mounting through holes 7 on the No. 1 connecting ring 6 and are locked with limiting nuts 12 to form a strong rigid connection. This connection method not only facilitates installation and adjustment but also effectively constrains the axial displacement of the pipeline, dispersing possible axial forces through the connection structure and preventing stress from acting directly on the water-stop sealing part. In terms of sealing at the connection interface, the bottom sealing ring 14 fixed to the end of the No. 1 sleeve 1 is precisely embedded in the annular sealing groove 15 at the end of the No. 2 sleeve 8, forming... A tight mechanical seal further prevents potential leakage along the sleeve connection gap. The inner reinforcement layer 13 on the inner side of the No. 1 sleeve 1 provides comprehensive protection. The innermost thermal insulation buffer layer 131 directly wraps the heating pipe, reducing heat loss and absorbing the thermal expansion and contraction and vibration of the pipe. The middle fireproof layer 132 can effectively insulate and retard fire in the event of a fire, preventing the fire from spreading along the pipe. The outermost waterproof layer 133 is tightly integrated with the sleeve wall, sealing any possible micro gaps from the inside, forming a third waterproof barrier. It works together with the sleeve and water-stop ring to ensure excellent sealing integrity in the floor opening area through which the sleeve device passes.

[0026] In one embodiment, such as Figures 1 to 5As shown, a second connecting ring 9 is fixedly connected to the outside of the second sleeve 8. One side of the second connecting ring 9 is fixedly connected to the bottom connecting cover 10. Six fixing screws 11 are fixedly connected at equal intervals inside the second connecting ring 9 and the bottom connecting cover 10. The first connecting ring 6 has six mounting through holes 7 that mate with the fixing screws 11. Limit nuts 12 are threaded on the outside of the fixing screws 11.

[0027] It should be noted that in this embodiment, by setting the second connecting ring 9, the bottom connecting cover 10, the fixing screw 11, the mounting through hole 7, and the limiting nut 12, a detachable rigid connection between the second sleeve 8 and the first sleeve 1 is achieved. This structure is not only accurate in installation and easy to operate, but also has a firm and reliable connection. It can effectively resist the stress caused by the axial displacement and vibration of the pipeline, ensuring the overall structural stability of the sleeve device during long-term use and preventing the risk of leakage due to loose connection.

[0028] In one embodiment, such as Figures 1 to 5 As shown, the first water-stop ring 2 has three internal reinforcing support rings 4 fixed at equal intervals inside.

[0029] It should be noted that in this embodiment, three equidistant inner reinforcing rings 4 are set inside the No. 1 waterstop ring 2, which significantly enhances the structural strength and rigidity of the No. 1 waterstop ring 2 itself. This can prevent the waterstop ring from deforming or breaking during concrete pouring, vibration, or when subjected to uneven external pressure, ensuring that it is tightly bonded to the floor slab concrete, thereby playing its key role as the first line of seepage prevention and sealing in a long-lasting and reliable manner.

[0030] In one embodiment, such as Figures 1 to 5 As shown, multiple reinforcing members 17 are fixedly connected at equal intervals to the top and bottom of the No. 2 water-stop ring 5, and all the multiple reinforcing members 17 are fixedly connected to the No. 1 sleeve 1.

[0031] It should be noted that in this embodiment, multiple reinforcing members 17 are provided at the top and bottom of the second water-stop ring 5 and fixed to the first sleeve 1, which greatly enhances the connection strength and anti-peeling ability between the second water-stop ring 5 and the main body of the first sleeve 1. This can effectively resist the pulling of the water-stop ring connection part caused by thermal expansion and contraction stress caused by temperature changes, pipeline vibration or concrete shrinkage deformation, and ensure the long-term effectiveness of the second water-stop ring 5 as the second anti-seepage barrier, and prevent cracks from forming at stress concentration points that lead to leakage.

[0032] In one embodiment, such as Figures 1 to 5 As shown, it also includes an inner reinforcement layer 13, which includes a thermal insulation buffer layer 131, a fireproof layer 132, and a waterproof layer 133. The inner side of the first sleeve 1 is fixed with the waterproof layer 133, the inner side of the waterproof layer 133 is fixed with the fireproof layer 132, and the inner side of the fireproof layer 132 is fixed with the thermal insulation buffer layer 131.

[0033] It should be noted that in this embodiment, the thermal insulation buffer layer 131 can reduce heat loss from the heating pipe and absorb pipe vibration, while the fireproof layer 132 can effectively block or delay the spread of flames and high temperatures through the sleeve gaps, thereby improving the building's fire safety level.

[0034] In one embodiment, such as Figures 1 to 5 As shown, the thermal insulation buffer layer 131 is made of rubber and plastic thermal insulation material, the fireproof layer 132 is made of fireproof rock wool material, and the waterproof layer 133 is made of polyurethane sealant.

[0035] It should be noted that in this embodiment, the thermal insulation buffer layer 131 is made of rubber and plastic thermal insulation material, which has good thermal insulation performance and elasticity, can effectively save energy and buffer pipe displacement, the fireproof layer 132 is made of fireproof rock wool material, which provides excellent fire resistance and thermal insulation performance, and meets the building fire protection requirements, and the waterproof layer 133 is made of polyurethane sealant, which has high adhesion, elasticity and water resistance, can tightly fill gaps and adapt to certain deformations.
