Description

Technical Field

[0001] This utility model relates to the field of construction, and in particular to a waterproof structure for through-wall pipes. Background Technology

[0002] Through-wall pipes are important components in building engineering used to protect pipes when they pass through walls, achieve waterproof sealing, and ensure structural connection. Their selection and construction directly affect the functionality and durability of buildings. In particular, the quality of waterproof sealing will directly affect the quality of the building.

[0003] Currently, the waterproof sealing structure used for through-wall pipes involves first installing a sleeve and inserting it into the wall, then filling the gap between the sleeve and the through-wall pipe with waterproof material to achieve a waterproof seal. However, this simple sealing method, coupled with the differences in the coefficients of thermal expansion and contraction of different materials, easily leads to delamination or cracking between the waterproof material and the sleeve, between the waterproof material and the through-wall pipe, and between the sleeve and the wall, ultimately causing leakage problems. Therefore, this improved solution has been developed. Utility Model Content

[0004] The purpose of this utility model is to provide a waterproof structure for through-wall pipes, which can achieve better waterproof sealing performance, thereby ensuring building quality and extending building service life.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a waterproof structure for a through-wall pipe, comprising a wall, a wall opening in the wall, a sleeve installed in the wall opening, a through-wall pipe segment installed in the sleeve, and a waterproof layer filling the space between the through-wall pipe segment and the sleeve. Each through-wall pipe segment located outside the wall is detachably and fixedly provided with a support member. Each outer peripheral wall of the through-wall pipe segment is slidably fitted with a pressure ring located between the outer wall and the support member. Each outer peripheral wall of the through-wall pipe segment is fitted with a main sealing member located between the wall and the pressure ring. The support member is provided with a clamping member that drives the pressure ring to move towards the main sealing member. The main sealing member constitutes a seal between the pressure ring and the through-wall pipe segment, and between the pressure ring and the wall.

[0006] By adopting the above technical solution, the clamping component drives the pressure ring to move towards the main sealing component, causing the pressure ring to press the main sealing component against the outer peripheral wall of the through-wall pipe section and the wall, thereby achieving a seal between the pressure ring and the through-wall pipe section, and between the pressure ring and the wall. This makes it difficult for water to penetrate inward, and the continuous clamping force applied by the clamping component effectively solves the problem of gaps caused by thermal expansion and contraction, thus achieving better waterproof sealing performance, ensuring building quality, and extending the building's service life.

[0007] The further configuration is as follows: an extrusion groove is formed between the inner ring of the pressure ring and the through-wall pipe section, the extrusion groove has an insertion opening facing the wall, the outer peripheral wall of the extrusion groove has an extrusion slope that extends to the opposite side of the wall and gradually narrows, and the main sealing element extends through the insertion opening and fills the extrusion groove.

[0008] By adopting the above technical solution, the main seal extends into the extrusion groove, and the extrusion slope formed is used to change the direction of the force, so that the force applied by the pressure ring can better drive the main seal to press against the outer peripheral wall of the through-wall pipe section, thereby achieving a stable seal between the pressure ring and the through-wall pipe section.

[0009] The main seal is further configured to form a seal between the pressure ring and the sleeve.

[0010] By adopting the above technical solution, a better seal can be achieved at the joints formed between the two pairs of parts.

[0011] The configuration is further defined as follows: the pressure ring is provided with an isolation cover that moves with the pressure ring and covers the main sealing element; a secondary sealing assembly is provided between the isolation cover and the wall; and the secondary sealing assembly is located inside the isolation cover.

[0012] By adopting the above technical solution, multiple seals are formed by coordinating the design of the sealing components to achieve a better sealing effect. Furthermore, the isolation cover is used to block the seal components from the outside environment and the main sealing component from the outside environment, thereby extending the service life of the two sealing components.

[0013] The sealing assembly is further configured such that: a force-bearing ring reciprocates along the axis of the through-wall pipe section, a sealing element disposed between the force-bearing ring and the wall, and a compression spring that drives the force-bearing ring to move toward the sealing element.

[0014] By adopting the above technical solution, the compression spring applies a pressing force against the wall to the sealing element through the force ring, thereby forming a waterproof seal. Moreover, the elastic compression force applied by the compression spring is not affected by the thermal expansion and contraction of the material, thus achieving a better sealing effect.

[0015] The configuration is further defined as follows: the force-bearing ring slides against the inner wall of the isolation cover to guide the force-bearing ring to reciprocate along the axis of the through-wall pipe section, and the isolation cover has a positioning groove for the compression spring to be embedded.

[0016] By adopting the above technical solutions, convenient assembly can be achieved.

[0017] The further configuration is as follows: the bearing member is a clamp installed on the through-wall pipe section, the abutting member is a abutting bolt that passes through the clamp and is threadedly connected to the clamp, and multiple abutting bolts are arranged around the center of the through-wall pipe section.

[0018] By adopting the above technical solution, the clamp structure can achieve convenient and detachable fixing of the load-bearing component on the through-wall pipe section, and apply a tightening force to the pressure ring through the threaded structure.

[0019] A further configuration is provided: a sealing section extending into the sleeve and the through-wall pipe section is formed on the main sealing element.

[0020] By adopting the above technical solution, a better seal can be formed between the sleeve and the through-wall pipe section.

[0021] A further feature is provided: the sleeve is provided with a water-blocking ring extending into the interior of the wall.

[0022] By adopting the above technical solution, the water-blocking ring is set to reduce the infiltration of water into the wall, thereby achieving a better sealing effect.

[0023] In summary, this utility model has the following beneficial effects: it can achieve better waterproof and sealing performance, thereby ensuring building quality and extending building service life. Attached Figure Description
