DETAILED DESCRIPTION OF THE INVENTION

[0039] According to the present invention, the chained foam sealing system can have various alterations and embodiments, and specific embodiments are shown in diagrams and demonstrated in detail. However, the scope of the present disclosure should be not limited by specific embodiments and the present disclosure may be variously modified and altered with addition, change, deletion or supplement of elements by those skilled in the art to which the present disclosure pertains without departing from essential features of the present disclosure. This is also included in the scope of the present invention's spirit.

FIG. 2 is a perspective view displaying a housing unit interconnected in a series, which is connected to the connecting unit of the chained foam sealing system according to an embodiment of the present invention.

FIG. 4 is a perspective view displaying a combination of a housing unit and a connecting unit of chained foam sealing system according to an embodiment of the present invention. FIG. 5 is a perspective view displaying a connecting unit of chained foam sealing system according to an embodiment of the present invention.

[0041] According to chained foam sealing system of the present invention, as shown in FIG. 1, chained foam sealing system is installed around a penetration hole 30 of a pipe 20 penetrating wall structure 10 dividing space and consists of inflammable materials to avoid spread of flames in case of fire, sealing the penetration hole of a pipe 20. The chained foam sealing system comprises a housing unit 100, a connecting unit 200 and a fixing unit 300.

[0042] As shown in FIG. 2 and FIG. 4, a housing unit 100 forms a body having designated accommodatable space.

[0043] According to the present invention, a housing unit 100 of chained foam sealing system includes a roof face 110, a bridge face 120 and a chamber 130.

[0044] First, a roof face 110 forms domed uneven structure on the outer side of a housing unit 100.

[0045] A bridge face 120 functions as making uneven structure connecting a dome and the other one of a roof face 110.

[0046] A chamber 130 has accommodatable space inside a housing unit 100. As shown in FIG. 3, a chamber 130 preferably accommodates fireproof foaming materials which expand when a heat energy exceeding a threshold value affects the chamber.

[0047] More specifically, fireproof foaming materials 131 are called fireproof filling such as fire pad, firestop sealant, thermal insulation material or expanding tape.

[0048] The fireproof foaming materials 131 have excellent flexibility, adhesion, elasticity and water resistance due to hermetic filling as incombustible ones, remarkable adhesion simultaneously after water(moisture) evaporation and are preferably no-crack after hardening.

[0049] The fireproof foaming materials 131 rapidly and stably foams with small quantity and are able to seal a penetration hole 30.

[0050] Also, a chamber 130 faces towards the inner diameter of a pipe 20 contacting the outer face of a pipe 20. When the chamber is heated and the pipe 20 is damaged by the heat, fireproof foaming materials 131 contained in a chamber 130 expands inside the penetration hole 30 and seals the penetration hole 30 blocking spread of flames.

[0051] The boundary of a chamber 130 preferably expands outwards to cover firmly so that fireproof foaming materials 131 emit inside and expand in a penetration hole 30.

[0052] Not only a housing unit 100 contains fireproof foaming materials 131, but also they prevents a housing unit 10 coming out and emits only into the inside of a penetration hole 30 to cover as a fence when fireproof foaming materials 131 expand.

[0053] As shown in FIG. 2, a connecting unit 200 is connected to a housing unit 100, which makes a housing unit 100 interconnected in a series.

[0054] According to the present invention, a connecting unit 200 comprises a supporting cover 210 and a chain link 220.

[0055] A supporting unit consists of a main body of a connecting unit 200 covering the connecting unit 200.

[0056] As shown in FIG. 3, a supporting unit is preferably adjacent to the outer diameter of a pipe 20 covering the outer diameter of the pipe 20 in order to make fireproof foaming materials 131 expand only toward a penetration hole 30.

[0057] A chain link 220 has one or more combining holes in order to combine a housing unit 100.

[0058] As shown from FIG. 2 to FIG. 4, one side of a housing unit 100 is combined with a combining hole of a chain link 220 in a chain form, which makes hinge-bending motion.

[0059] The hinge-bending motion is used for combining more than two devices, which motion makes mechanical rotation in between the two devices. A housing unit 100 linked in a series by a hinge-attached chain link 220 is able to roll flexibly in a penetration hole 30 of a pipe 20 by mechanical rotation.

[0060] A connecting unit 200 arbitrarily cut by the size of a connecting unit 200 makes the length of the housing unit 100 connected in a series, arbitrarily regulated, and arbitrarily matched by the diameter size of a pipe 20.

[0061] For instance, a connecting unit 200 can conveniently be cut out and installed as necessary although the diameter sizes of pipes 20 inside a building are different.

[0062] As shown in FIG. 4, a fixing unit 300 is located on one side of a housing unit 100 and fixed on the wall structure of a housing unit 100.

[0063] A fixing unit 300 of the present invention comprises an attaching part 310 and a fixing part 320.

[0064] The attaching part 310 is attached and fixed on one side of a housing unit 100. The attaching part 310 is formed in one housing unit 100 respectively, which is preferably located on a bridge face of a housing unit.

[0065] A fixing part 320 has a fixing hole to fix a housing unit 100 on wall structure. A fixing unit 300 is fixed with a piece on wall structure, which prevents a housing unit 100 breaking away from a penetration hole 30 of a pipe 20.

[0066] Furthermore, a fixing unit 300 is preferably attached on one housing unit 100, which makes the length of a housing unit 100 arbitrarily regulated and fixed with a piece on wall structure regardless of the length of the housing unit 100.

[0067] The scope of the present disclosure should be determined by listed items, and the brackets of claims are listed not for optional limit but for clear elements, and contents of brackets should be understood as essential elements.
