Description

{Penetrating tube sleeve with slope formation and length adjustment}

The present invention relates to a sleeve for installing a penetrating pipe in a building and civil engineering structure, and more particularly, to a sleeve designed to enable the formation of an inclined surface and adjustment of the length. The present invention relates to a technology for improving the efficiency and stability of a pipe installation work by forming an inclined structure inside the sleeve to prevent external inflow such as rainwater or condensation, and providing a structure capable of adjusting the length according to the thickness of a building wall.

Generally, sleeve technology is used in buildings to pre-form penetration holes in reinforced concrete walls or beams for pipe installation. Sleeves are designed to allow pipes to penetrate walls and are usually cylindrical in structure. Existing sleeves are manufactured in a certain length and diameter, and the appropriate model must be selected according to the wall thickness and pipe diameter during installation.

In the existing technology, it was common to adjust the sleeve length according to the wall thickness, or to use separate insulation or foam to prevent rainwater from flowing in and condensation from the outside environment. However, this method had a complicated installation process, and the angle of the sleeve could be distorted after installation due to the expansion force of the insulation. In addition, if the sleeve installed on the wall was placed in a certain horizontal state, rainwater or condensation could flow into the sleeve, causing problems such as leakage or freezing.

Therefore, in order to complement the shortcomings of the existing sleeve technology, the development of a sleeve having a structure capable of forming a slope and a function of adjusting the length according to the wall thickness was required. The present invention was proposed to solve these technical problems.

Figure 1 is a conceptual diagram of a through-type pipe sleeve capable of forming a slope and adjusting the length according to the present invention.

FIG. 2 is a conceptual diagram of a through-type pipe sleeve capable of forming a slope and adjusting the length according to another embodiment of the present invention.

The present invention relates to a through-type pipe sleeve, which is installed in a pipe hole formed through a wall (10) and has an inclined surface formed and a length adjustable, and includes a pipe fixing means (100) installed in each of the pipe holes to fix the pipe to the pipe hole, and the pipe fixing means (100) includes a first sleeve (110) inserted from one direction of the pipe hole and a second sleeve (120) inserted from one direction of the first sleeve (110) and fixed to the first sleeve (110) at a set angle, and the inner wall of the second sleeve (120) is formed asymmetrically so that an inclined surface is formed according to the angle at which it is fixed to the first sleeve (110), and the length of the pipe fixing means (100) is set according to the length at which the second sleeve (120) is fixed to the first sleeve (110).

In this embodiment, the configuration and operating principle of a through-type pipe sleeve capable of forming a slope and adjusting the length can be specifically explained. A pipe fixing means (100) is installed in a pipe hole penetrating a wall (10), and can stably fix a pipe through the pipe hole and form a slope.

The pipe fixing means (100) may be composed of a first sleeve (110) and a second sleeve (120). The first sleeve (110) has a cylindrical structure, and its outer wall may be fixed in close contact with the inner wall of the pipe hole. A flange (112) extended to a predetermined height is provided at one end of the first sleeve (110), and by making contact with the wall (10), the sleeve may be supported so as not to be separated from the pipe hole. Screw threads are formed on the inner wall of the first sleeve (110), and the sleeve may be fastened with the second sleeve (120).

The second sleeve (120) is formed in a cylindrical shape having the same inner and outer diameters as the first sleeve (110), and may have screw threads formed on the outer wall to engage with the screw threads of the first sleeve (110). The inner wall of the second sleeve (120) is designed asymmetrically, so that an inner slope can be formed when the second sleeve (120) is rotated. For example, the inner wall of the second sleeve (120) may be designed with a thick structure on one side and a thin structure on the other side, so that an inclined surface can be provided according to a change in angle.

The first sleeve (110) and the second sleeve (120) can be connected in a rotational manner. The user can adjust the second sleeve (120) to be inserted into or removed from the first sleeve (110) by manipulating the screw thread by rotating the second sleeve (120) clockwise or counterclockwise. Through this manipulation, the insertion length of the second sleeve (120) is changed, and accordingly, the overall length of the pipe fixing means (100) can be adjusted. In addition, the inclination of the inclined surface can be adjusted according to the insertion depth and angle of the second sleeve (120), and this can help to accurately set the piping direction inside the pipe hole.

For example, the first sleeve (110) and the second sleeve (120) may be designed to have an inner diameter of 300 mm and an outer diameter of 350 mm, respectively, and the wall (10) thickness may be applied in various ways from 200 mm to 600 mm. The flange (112) of the first sleeve (110) may have a thickness of 10 mm and a height of 20 mm, and the second sleeve (120) may have a screw pitch set to 5 mm to enable precise angle adjustment.

The asymmetrical inner wall design of the second sleeve (120) can be designed so that the maximum slope of the slope can be set to 3 degrees. This can be utilized to prevent backflow of rainwater or to increase the efficiency of air circulation pipes.

Therefore, this embodiment can be applied to various wall (10) environments by enabling the formation of a slope and length adjustment with only simple manipulation of the sleeve, and can provide stability of pipe installation and convenience of work at the same time.

Next, the first sleeve (110) includes a case (111) formed as a cylinder having an outer wall in contact with the inner wall of the pipe hole and having a predetermined thickness, and a flange, which is a cylinder formed by extending to a predetermined height at one end of the case (111), may be provided on the case (111).
The case (111) is divided into a sunken inner wall (1111) having screw threads formed on the inner side, and a protruding inner wall (1112) formed in a shape thicker than the sunken inner wall (1111), and the inner diameter of the flange (112) is the same as the inner diameter of the protruding inner wall (1112), and the outer diameter of the flange (112) is formed to be a predetermined length longer than the outer diameter of the case (111), so that the flange (112) is provided to fix the first sleeve (110) to the wall (10) while coming into contact with the wall (10), and the second sleeve (120) is formed as a cylindrical body having a predetermined thickness and an outer wall coming into contact with the inner wall of the first sleeve (110), and the second sleeve (120) has screw threads formed on the outer wall to be connected with the screw threads of the sunken inner wall (1111), and the It is characterized in that the length of the inner wall (1111) and the length of the second sleeve (120) are the same length.

In this embodiment, the specific physical structure and joining mechanism of the first sleeve (110) and the second sleeve (120) can be described. The first sleeve (110) has a structure that can be stably fixed to the inner wall of the pipe hole, and the second sleeve (120) can include a mechanism that can be fastened to the first sleeve (110) to adjust the length and angle.

The first sleeve (110) may be formed of a cylindrical case (111) whose outer wall is in contact with the inner wall of the pipe hole and can be stably installed. The outer diameter of the case (111) is designed to be slightly smaller than the inner diameter of the pipe hole, so that it can be fixed through frictional force during installation. A flange (112) that is in contact with the wall (10) may be provided at one end of the case (111), and the flange (112) may be formed with a thickness of 5 mm and a height of 10 mm, so as to support the case (111) so that it does not come off from the pipe hole.

The inside of the first sleeve (110) can be divided into a recessed inner wall (1111) with threads formed therein and a thick protruding inner wall (1112). The threads of the recessed inner wall (1111) are set at a pitch of 3 mm, so that the second sleeve (120) can be stably fastened while rotating. The protruding inner wall (1112) is formed to be about 20% thicker than the recessed inner wall (1111), so that it can provide additional durability and support.

The second sleeve (120) has an outer diameter that matches the inner diameter of the first sleeve (110), and a screw thread may be provided on the outer wall to engage with the sunken inner wall (1111) of the first sleeve (110). The screw thread has the same pitch as the screw thread of the first sleeve (110), and the length and slope can be adjusted by rotating the second sleeve (120). The inner wall of the second sleeve (120) is designed asymmetrically, so that one side has a thick structure to form a slope of the slope.

The first sleeve (110) and the second sleeve (120) may be manufactured from aluminum alloy to minimize frictional resistance when fastened. For example, the first sleeve (110) may be designed to have an outer diameter of 200 mm and a thickness of 5 mm, and the second sleeve (120) may be formed to have an inner diameter of 190 mm and a thickness of 5 mm. This structure can provide high strength and light weight at the same time.

When installed, the first sleeve (110) can be mounted on the wall (10) via the flange (112), and the second sleeve (120) can be rotated and fastened by engaging the screw threads of the first sleeve (110). The user can insert the second sleeve (120) by rotating it so that it engages the screw threads of the recessed inner wall (1111). When fastened, the second sleeve (120) can be stably fixed by being in close contact with the protruding inner wall (1112). At this time, the length of the sleeve can be adjusted depending on the rotation direction of the second sleeve (120), and an inclined surface can be formed due to the asymmetrical structure of the inner wall.

In this embodiment, the wall thickness (10) of the pipe hole can be applied in various ways from 200 mm to 600 mm, and the length adjustment range of the second sleeve (120) can be expanded up to a maximum of 400 mm. Through this design, it is easy to adjust the sleeve according to the change in the wall thickness (10), and the formation of the slope can be implemented with just a simple operation. Through this, the stability of the pipe installation and the convenience of work can be improved in various environments.

Next, the pipe fixing means (100) further includes an elastic cable (132) having one end fixed to the protruding inner wall (1112) and a hook (133) provided at the other end, a first ring (1311) mounted on an exposed surface (1113) having an X-direction vector provided at one end of the recessed inner wall (1111) as a normal vector, and a second ring (1312) mounted on an insertion surface (121) provided at one end of the second sleeve (120) and parallel to the exposed surface (1113), and the elastic cables (132) are provided in a plurality of circular arrangements at equal intervals on the protruding inner wall (1112), and the first rings (1311) are provided in a circular arrangement at equal intervals on the exposed surface (1113) in the same number as the elastic cables (132), and the The second ring (1312) is provided in the same number as the first ring (1311) on the insertion surface (121) at the same intervals in a circular arrangement, the hook (133) is formed in a form that can be attached to or detached from the first ring (1311) or the second ring (1312), and the elastic cable (132) is attached to the second ring (1312) to provide tension in the direction in which the second sleeve (120) is pressed against the first sleeve (110).

In this embodiment, an elastic cable (132) and a ring structure used to provide additional fixing stability of a pipe fixing means (100) can be described. This configuration can reinforce the bonding strength between sleeves and prevent sleeve detachment due to external impact or vibration.

The pipe fixing means (100) may include a plurality of elastic cables (132) to improve the fastening force between the first sleeve (110) and the second sleeve (120). The elastic cables (132) may be made of high-strength synthetic fiber or spring steel, and may be designed in a form in which the length can be adjusted. For example, the diameter of the elastic cables (132) may be set to about 5 mm, and the initial tension may be set to 50 N.

One end of the elastic cable (132) can be fixed to the protruding inner wall (1112) of the first sleeve (110). For this fixation, a circular first ring (1311) can be provided on the exposed surface (1113) having a normal vector in the X direction on the protruding inner wall (1112). The first ring (1311) can be formed with an inner diameter of 10 mm and an outer diameter of 15 mm, and a hook (133) of the cable can be inserted and fastened.

The other end of the elastic cable (132) can be connected to a second ring (1312) provided on the insertion surface (121) of the second sleeve (120). The second ring (1312) can be manufactured to have the same size and shape as the first ring (1311) and can be arranged in a circular arrangement on the insertion surface (121) of the second sleeve (120). This arrangement can be designed so that the interval between the rings is maintained the same.

During the installation process, the user can fasten the hook (133) of the elastic cable (132) connected to the first ring (1311) to the second ring (1312) before assembling the first sleeve (110) and the second sleeve (120). At this time, the elastic cable (132) can be set to generate a slight tension, which can provide a force to press the second sleeve (120) toward the protruding inner wall (1112) of the first sleeve (110).

The elastic cable (132) can provide tension that acts perpendicularly to the fastening direction of the sleeve. Through this, the fastening state between the first sleeve (110) and the second sleeve (120) can be maintained, and the sleeve can be prevented from being detached due to external impact or vibration.

In this embodiment, elastic cables (132) may be arranged in a circular arrangement to enhance the fastening stability of each sleeve. For example, eight elastic cables (132) may be arranged at equal intervals, and each cable may provide a tension of about 50 to 100 N. This can greatly enhance the fastening force and fixing stability of the sleeve.

In addition, a tension adjustment means (141) may be additionally included to allow the user to adjust the tension of the elastic cable (132) as needed. The tension adjustment means (141) may be placed outside the sleeve and may increase or decrease the tension by adjusting the length of the cable. This design can increase user convenience while responding to various installation environments.

Next, a cable penetration hole (142) penetrating the protruding inner wall (1112) is provided in the protruding inner wall (1112), the elastic cable (132) is connected to one side of the protruding inner wall (1112), a tension adjusting means (141) for adjusting the tension of the elastic cable (132) is provided, and the elastic cable (132) is characterized in that one end is connected to the tension adjusting means (141), is connected by penetrating the cable penetration hole (142), and is provided with a hook (133) at the other end for attachment to the first ring (1311) or the second ring (1312).

In this embodiment, the structure of the tension adjustment means (141) and the cable penetration hole (142) provided in the pipe fixing means (100) can be described in detail. This configuration can contribute to precisely adjusting the tension of the elastic cable (132) and maintaining the fastening stability of the sleeve.

A plurality of cable penetration holes (142) may be provided in the protruding inner wall (1112) of the pipe fixing means (100) to pass an elastic cable (132) through. Each cable penetration hole (142) may have a circular or oval cross-section, and may be designed to have a diameter of about 8 to 10 mm. The cable penetration holes (142) may be arranged at regular intervals on the periphery of the protruding inner wall (1112), and such arrangement may help to evenly distribute the tension of the cable.

The cable penetration hole (142) may be formed in a structure that penetrates from the outside to the inside of the protruding inner wall (1112). A low-friction coating may be applied to the inner wall of the penetration hole to reduce friction, which may help the elastic cable (132) move smoothly when tension changes. This coating may be composed of a PTFE (polytetrafluoroethylene) material.

The tension adjusting means (141) may be arranged on the outside of the protruding inner wall (1112). The tension adjusting means (141) may be formed of a screw-type adjuster, a ratchet structure, or a gear-based rotary adjuster. In the present embodiment, a screw-type adjuster may be utilized. The screw-type adjuster may be designed to have an outer diameter of about 20 mm and a length of about 30 mm, and the operating handle may be formed in a protruding shape at 90-degree intervals.

A user can adjust the length of the elastic cable (132) by rotating the screw-type adjuster. The adjuster is coupled with a clamp connected to one end of the cable, so that the tension of the cable can be increased or decreased depending on the direction of rotation of the adjuster. For example, rotating the adjuster clockwise can increase the tension as the cable shortens, and rotating it counterclockwise can decrease the tension as the cable relaxes.

The cable penetration hole (142) can be designed to fix the position of the elastic cable (132) while allowing the cable to move freely according to the operation of the tension adjustment means (141). This allows the user to adjust the fastening state of the sleeve to maintain the optimal angle for forming a slope.

In this embodiment, in order to improve the convenience of operation of the tension adjustment means (141), an operation handle may be included in the screw-type adjuster. The operation handle may be ergonomically designed to help the user operate it with minimal force. The surface of the handle may include a texture for anti-slip, which may provide operational stability during operation.

By combining the design of the cable penetration hole (142) and the tension adjustment means (141), the user can precisely adjust the slope and length while maintaining the fixing stability of the sleeve in various installation environments. With this configuration, the pipe fixing means (100) can provide stable performance even in changes in the external environment.

Next, the width of the cable penetration hole (142) is formed to the same length as the width of the second ring (1312), and when the second ring (1312) is inserted into the cable penetration hole (142), the insertion surface (121) and the protruding inner wall (1112) come into contact.

In this embodiment, the specific structure and interaction of the cable penetration hole (142) and the second ring (1312) can be described in detail. This configuration can be designed in a way that can maximize the fastening stability and efficiency of the sleeve.

The cable penetration hole (142) may be formed to penetrate from the outer surface to the inner surface of the protruding inner wall (1112). This penetration hole may be designed with precise dimensions in consideration of the connection with the second ring (1312). In this embodiment, the cable penetration hole (142) may be designed to have a width of about 10 mm and a height of about 5 mm, which may facilitate the insertion and fixing of the second ring (1312).

The second ring (1312) may be formed into a flat structure, and may be designed to have an outer diameter of about 8 mm, which is slightly smaller than the width of the cable penetration hole (142). As a result, the second ring (1312) may be stably fixed without shaking while having an appropriate amount of play when inserted into the cable penetration hole (142). The second ring (1312) may be manufactured from a durable material such as stainless steel or aluminum alloy to increase rigidity.

When the second ring (1312) is inserted into the cable penetration hole (142), the insertion surface (121) of the second ring (1312) and the inner surface of the protruding inner wall (1112) may come into contact with each other. This contact may serve to improve the fastening stability of the sleeve. In addition, during the insertion process, a friction-reducing coating (e.g., PTFE coating) provided on the outer edge of the second ring (1312) may reduce friction with the cable penetration hole (142) to help the insertion be performed smoothly.

In this embodiment, a stopper structure for limiting the insertion depth of the second ring (1312) may be provided at the upper end of the cable penetration hole (142). This stopper may be formed in a protruding shape, and when the second ring (1312) is inserted, it may come into contact with the stopper to prevent excessive insertion. The height of the stopper may be designed to be about 1 mm, which may support stable fixing of the second ring (1312).

In addition, a round edge with a thickness of 0.5 mm may be formed at the upper and lower ends of the cable penetration hole (142) to minimize friction with the cable. This round edge may prevent damage that may occur when the second ring (1312) and the cable are inserted and fixed.

The configuration of this embodiment can be designed in a structure in which, when the second ring (1312) is inserted into the cable penetration hole (142), the inner surface of the protruding inner wall (1112) and the outer surface of the second ring (1312) are in close contact to maximize the fastening stability. In addition, as the second ring (1312) is inserted into the cable penetration hole (142), the protruding inner wall (1112) comes into contact with the insertion surface (121) of the second ring (1312), so that the entire sleeve can be stably fixed.

Through this, the present embodiment can provide a mechanical principle that allows a pipe sleeve with a sloped surface and adjustable length to operate stably even under external impact or load. This design simplifies the installation and maintenance of the sleeve, and can maintain high reliability in various working environments.
