Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and specifically relates to an external wall sleeve protection and seepage prevention device. Background Technology

[0002] During the construction of a building project, after the main project is completed, the construction of outdoor supporting projects is carried out. During the outdoor construction process, the external wall sleeves reserved in the main structure are easily damaged, and during the rainy season, the external wall sleeves need to be sealed to prevent rainwater leakage and backflow. Existing technologies also include some external wall sleeve sealing devices, such as patent CN115234713B, a combined device for sealing external wall water and electricity through-wall sleeves. This device includes a water and electricity through-wall sleeve fixedly embedded in the wall, with a cylindrical shell that opens at the rear side fitted onto the outer front side of the sleeve. This invention installs the cylindrical shell on the outer front side of the water and electricity through-wall sleeve to be sealed. Then, by rotating a turntable, a first arc-shaped plate clamps the outer side of the sleeve. A second arc-shaped plate then seals the rear opening of the cylindrical shell. This allows the device to be installed on water and electricity through-wall sleeves of different diameters, sealing the front side of the sleeve. Finally, by rotating a threaded rod into a threaded groove, a conical rubber sleeve seals the rear side of the sleeve. This facilitates the sealing operation of water and electricity through-wall sleeves and meets usage requirements. However, its structure is too complex, making construction troublesome and costly. Utility Model Content

[0003] This utility model provides an external wall sleeve protection and seepage prevention device, which can solve the problems pointed out in the background art.

[0004] An external wall sleeve protection and seepage prevention device includes a sleeve body, a fixing component on the sleeve body for fixing the sleeve body to the external wall sleeve, a sliding sealing gasket assembly inside the sleeve body, the sealing gasket assembly reciprocating along the length of the sleeve body, a connecting compression spring on the outer side of the sealing gasket assembly, and the sealing gasket assembly sealing one end of the external wall sleeve by applying force through the compression spring.

[0005] Preferably, the sealing gasket assembly includes a rigid gasket ring and a flexible gasket body disposed at the center of the rigid gasket ring.

[0006] Preferably, the rigid gasket is a metal gasket, and the flexible gasket is a rubber gasket.

[0007] Preferably, the metal gasket body is a steel gasket body, and the rubber gasket body is a hard rubber gasket body.

[0008] Preferably, the fixing component is a bolt arranged in a circular array on the sleeve body, and the bolt reciprocates radially.

[0009] Preferably, the sleeve body is a steel sleeve body.

[0010] Beneficial effects: This utility model provides an external wall sleeve protection and seepage prevention device, which simplifies the structure while achieving sealing, protection and seepage prevention. It has the advantages of simple structure, easy operation and low cost. Moreover, due to the reciprocating sliding of the sealing gasket assembly and the combination of compression spring, it can adapt to sleeves of different exposed lengths. Attached Figure Description

Detailed Implementation

[0012] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0013] Example 1: As Figure 1-2 As shown in the figure, an embodiment of the present invention provides an external wall sleeve protection and seepage prevention device, including a sleeve body 1. The sleeve body 1 is provided with a fixing component, which is used to fix the sleeve body 1 to the external wall sleeve. The sleeve body 1 is provided with a sliding sealing gasket assembly 2. The sealing gasket assembly 2 reciprocates along the length direction of the sleeve body 1. The outer side of the sealing gasket assembly 2 is provided with a connecting compression spring 3. The sealing gasket assembly 2 is sealed to one end of the external wall sleeve by applying force through the compression spring 3.

[0014] Specifically, the sealing gasket assembly 2 includes a rigid gasket ring 21 and a flexible gasket body 22 disposed at the center of the rigid gasket ring 21. The flexible gasket body 22 can better seal and cover the end of the external wall sleeve. The rigid gasket ring 21 is a metal gasket ring, and the flexible gasket body 22 is a rubber gasket body. The metal gasket ring is a steel gasket ring, and the rubber gasket body is a rigid rubber gasket body.

[0015] Specifically, the fixing component is a bolt 4 arranged in a circular array on the sleeve body 1, the bolt 4 reciprocating radially, and the sleeve body 1 is a steel sleeve body.

[0016] Construction steps and methods of this utility model: Place the sleeve body 1 onto one end of the outer wall sleeve, press the sealing gasket assembly 2 onto the end of the outer wall sleeve, and tighten all the bolts 4 inwards to press them against the outer wall of the outer wall sleeve, so as to stably connect the sleeve body 1 to the outer wall sleeve.

[0017] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
