Description

43794/IL/- 1 - DEVICE FOR A PIPE LEAD THROUGH Field of the Invention The present invention relates to the field of feed-through and sealing tubes for pipes penetrating walls, ceilings, floors, or any other suitable structure.

Background Multiple-story, multiple-unit office and housing structures are constructed with concrete floors and slabs for structural stability and load-bearing capacity. To enable the installation and supply of plumbing, efficient positioning of fluid flowing pipelines from the bases of the structures to their top floors is needed. The common method to perform this task is summarized according to the following steps: - Casting- this stage consists of the concrete casting of the entire floor or a slab of a housing structure according to generally accepted construction standards. Based on the supplied material by the constructor, the location of the opening (through which a pipe is designed to pass through) is sealed by a soft material such as polystyrene to enable an easier foramen formation. - Preparation- during this stage, the hole forming device is securely aligned and secured to be further used to create a foramen according to the desired diameter of the fluid flowing pipeline. It should be emphasized that during the process of foramen formation, the shape of the opening is inevitably distorted. - Layout- during this stage, the desired pipeline is laid through the created foramen in the ceiling and is further sealed to prevent movement during usage. Since the shape of the opening is distorted, sealing the opening in the most general case requires an effort that leads to unnecessary expenses.

In general, the layout procedure of fluid flowing pipeline is not ergonomic, time-consuming, and inefficient. Moreover, another major drawback is the formation of cracks in pipes that pressure changes and ground setting may cause. For example, ground settling: pipes can be damaged over time as the ground surrounding them settles. If the stress caused by the ground settling is sufficient, the pipes may 43794/IL/- 2 - eventually crack or break. The following invention intends to overcome the problems mentioned.

It is an object of the present invention to provide an adjustable septum that is used prior to the first stage of the process, allowing the user to concede on the second stage. Moreover, the unique structure of the proposed septum allows for saving time during the adjustments made in the final stage of the process and concedes to the sealing of the pipeline during the last stage. Furthermore, the special structure of the proposed septum allows an optimum adjustment during the casting stage, which further improves movement reduction compared to the process's final stage.

It is another object of the present invention to provide a sleeve for forming holes and/or openings through concrete or structures made by other building materials.

It is yet another object of the present invention to provide a sleeve that enables to establish fluid communication between two separate pipes in a sealed manner.

It is still an object of the present invention to provide a sleeve that connects two separate pipes flexibly, thereby preventing the formation of cracks in pipes that may be caused by pressure changes or ground setting that applies to the pipes in the sleeve surroundings.

Other objects and advantages of the invention will become apparent as the description proceeds.

Summary of the invention A sleeve for forming holes and openings through concrete or structures made by other building materials, comprising lower and upper members, wherein the lower member is adapted to receive a first pipeline and the upper member is adapted to receive a second pipeline in a way that forms a pipeline connector that enables a flow communication between said first and second pipelines, wherein each member is provided with at least two separate internally assembled rubber layers to assure an optimal internal sealing of fluid flowing between said first and second pipelines and through said sleeve. 43794/IL/- 3 - In one aspect, the sleeve further comprises an inner ring adapted to prevent leakages that may occur due to fluid flowing through said sleeve.

In one aspect, the inner ring has a triangular-like profile in order to tilt fluid away from the inner walls of said pipeline connector.

In yet another aspect, the sleeve further comprises an extender to form a pipeline connector with a height adjustment structure for adjusting the height of the pipeline connector with respect to the construction thickness required (e.g., for the concrete building).

According to an embodiment of the invention, the sleeve is cylindrical.

Detailed Description of the Invention The present invention is related to a sleeve for forming holes and openings that continuously extend through poured concrete structures, such as floors and slabs. 43794/IL/- 4 - The sleeve is used to be installed within a wall or shell so that a duct results in the finished state.

According to the preferred aspect of the invention, the cylindrical sleeve consists of lower and upper outer members.

The upper member is provided with at least two separate internally assembled rubber layers to assure an optimal internal grip of the fluid flowing pipeline to the upper outer member of the cylindrical sleeve.

Another aspect of the invention relates to the desired external structure of the upper member of the cylindrical sleeve. The upper member of the cylindrical sleeve has a graded external framework. Thus, it provides an optimal adjustment of the sleeve to the floor or slab during the concrete casting process.

Another aspect of the invention shows that the internal parts of the lower and upper members of the cylindrical sleeve are separated by an inclined rubber layer either integrated or added to the sleeve. The integrated or added inclined rubber layer serves to prevent fluid leakage from the side walls of the sleeve.

Another preferred aspect of the invention shows that the lower member is provided with two separate internally assembled rubber layers to assure an optimal internal grip of the fluid flowing pipeline to the lower outer member of the cylindrical sleeve.

Another aspect of the invention relates to the desired external structure of the lower member of the cylindrical sleeve. The lower member of the cylindrical sleeve has a graded external framework. Thus, it provides an optimal adjustment of the sleeve to the floor and slab during the concrete casting process.

According to another preferred aspect, the lower member is provided with a flange at its base. The sleeve can be secured to a concrete-forming baseplate by nailing or screwing through the flange or by any other suitable securing means.

Referring now to the drawings, Fig. 1 schematically illustrates a pipeline connector (10) in the form of a cylindrical sleeve, according to an embodiment of the invention. The external structure of pipeline connector (10) shows a circular structure, as noted 43794/IL/- 5 - by numeral (2). The internal feature, as indicated by numeral (3) of each one of the circular structures, consists of a sealing rubber that is placed tightly against the side walls of the connector. The main task of the rubber is to prevent the leaking of fluids against the side walls of the connector. For example, during the construction of a concrete ceiling, the connector can be fixed on its position by assembling screws in a spiral septum (e.g., as indicated by numeral (1) in the drawing). Moreover, as noted by numeral (2), the specific external structure allows for an optimum adjustment during the casting stage.

Fig. 2 shows a pipeline connector (10) with a first assembled pipe (4) inserted through an approximate end of the pipeline connector (10), and with a second assembled pipe (4) inserted through a distal end of the pipeline connector (10). This configuration allows connecting two separate pipes (such as pipes (4, 5)) to enable fluid communication between two pipes, wherein one pipe is located at one side of a concrete structure (e.g., a ceiling or wall) and the other pipe is located at the other side of the concrete structure. In such a configuration, the inner space of pipeline connector (10) is also used as a fluid transfer medium between the two pipes (4, 5). Moreover, such a configuration results in a device that connects two separate pipes flexibly, thereby preventing the formation of cracks in pipes that may be caused by pressure changes or ground settings that apply to the pipes in the sleeve surroundings Fig. 3 schematically illustrates an extender (20) for pipeline connector (10), according to an embodiment of the invention. Extender (20) has a form of a cylindrical sleeve and is adapted to receive, at least partially, the pipeline connector (10) in order to form a cylindrical telescopic/adjustable sleeve. The combination of extender (20) and pipeline connector (10) enables to fit pipeline connector (10) to different structure widths of a ceiling, a wall, or any other suitable structure through which the pipeline may pass through. The combination of extender (20) and pipeline connector (10) form a height adjustment structure that is capable of adjusting the height with respect to the construction thickness required for the concrete building. According to some embodiments of the invention, extender (20) comprises sealing rubbers that 43794/IL/- 6 - are placed tightly against the side walls of the connector as indicated by numerals 22, and 23 in the same manner as indicated by numerals 2 and 3 of Fig. 1.

According to an embodiment of the invention, extender (20) can be installed on its position by assembling screws either in a spiral septum indicated by numeral (11) or in a cylindrical septum indicated by numeral (12) in the figure.

Fig. 4A schematically illustrates pipeline connector (10) partially inserted within extender (20), according to an embodiment of the invention. Fig. 4B shows a cross-sectional view of Fig. 4A. According to an embodiment of the invention, in order to allow the insertion of pipeline connector (10) into extender (20), one of the ends of pipeline connector (10) needs to be removed (e.g., by cutting its distal or proximate end as shown in Fig. 4C). The insertion of pipeline connector (10) into extender (20) enables to achieve height adjustment. For example, one may set the desired length of the sleeve formed by combining pipeline connector (10) and extender (20) in order to fit the width of a wall or ceiling through which pipelines need to be installed.

Fig. 5 is a cross-sectional view of pipeline connector (10), according to an embodiment of the invention. In this embodiment, the inner section of the pipeline connector (10) comprises an inner ring (6) that is adapted to prevent leakages that may occur due to fluid flowing through pipeline connector (10). According to an embodiment of the invention, the inner ring (6) may have a triangular-like profile in order to tilt fluid toward the center of the pipeline connector (10) (i.e., away from the inner walls of the pipeline connector (10)). The terms "for example", "e.g.", and "optionally", as used herein, are intended to be used to introduce non-limiting examples. While certain references are made to certain example system components, other components can be used as well and/or the example components can be combined into fewer components and/or divided into further components. 43794/IL/- 7 - All the above descriptions and examples have been given for the purpose of illustration and are not intended to limit the invention in any way. Many different mechanisms and structures can be employed, all without exceeding the scope of the invention.
