Description

Penetration sleeve with lock ring for fireproof filler}

The present invention relates to a penetrating sleeve provided with fire-resistant filler that prevents the spread of fire between floors in the event of a fire in a building.

In general, buildings with a multi-story structure must form a through hole in the slab so that various pipes, such as drain pipes, can penetrate between floors. To this end, a through sleeve through which pipes can be inserted into the form for slab construction is installed. Afterwards, mortar is being poured.

The through sleeve installed in the form usually has an inner diameter larger than the outer diameter of the pipe. This is to enable the pipe to be easily inserted into the through sleeve in the future and to respond to deformations such as bending of the pipe. For this reason, a gap is created between the penetrating sleeve and the pipe, and in the event of a fire, flame or toxic gas can flow through this gap, causing the fire to spread between floors and increasing casualties.

Due to this problem, recently, a fire-resistant filler that expands due to heat in the event of a fire is provided between the penetrating sleeve and the pipe to prevent the spread of fire and minimize casualties. These fireproof fillers are generally made by injecting a separate structure inside the penetrating sleeve so that the penetrating sleeve and fireproof filler are integrated into one piece, and a method where the fireproof filler is mounted on the top or bottom of the penetrating sleeve using a separate mounting means. It is widely used.

However, the former method cannot be applied to remanufactured or already constructed penetrating sleeves, and has the disadvantage of having to manufacture separate molds for each penetrating sleeve standard.

In addition, the latter method has the advantage that the fire-resistant filler can be fixed within the through-sleeve by a mounting means, so it can be applied to a re-manufactured or already constructed through-sleeve. However, it is not easy to assemble and install the mounting means for fixing the fireproof filler, and even if installation is easy, there is a problem that it cannot be firmly fixed. The reason why the fire-resistant filler must be firmly fixed within the penetrating sleeve is because in the event of a fire, the fire-resistant filler expands in a uniform direction and must block the flame. However, if the fire-resistant filler is not firmly fixed, the fire-resistant filler shakes during expansion and does not expand uniformly, resulting in a problem in which the flame is not effectively blocked.

A penetrating sleeve having a fastening ring for a fireproof filler according to an embodiment of the present invention is embedded in a slab so that a granular pipe is positioned through the inside, and an insertion groove is formed in a vertical direction on the inner periphery, and a horizontal insertion groove is formed at the top of the insertion groove. A sleeve body through which a fastener is formed in the direction of the sleeve body, inserted into the lower side of the sleeve body and fixed to the inner periphery of the sleeve body, is formed in a ring structure of double partitions with an open upper part and a height, and a fireproof filler is accommodated therein. The outer periphery includes a fastening ring on which an insertion protrusion is protruding and is moved vertically along the insertion groove and then horizontally moved toward the fastener to be fastened.

Hereinafter, with reference to FIGS. 1 to 4, the components of the through sleeve 1 having a fastening ring for refractory filler according to a preferred embodiment of the present invention and the connection relationships between these components will be described in detail. .

First, referring to Figure 1, a sleeve body 10 is provided, which is installed in the form on which the slab 30 is to be constructed so that the granular pipe connected between the lower layer and the upper layer is positioned through, At the same time, the fastening ring 20, which will be described later, is installed.

On the inner periphery of this sleeve body 10, insertion grooves 11 are formed vertically at four locations at 90-degree intervals, and these insertion grooves 11 allow the insertion protrusion 25 of the fastening ring 20, which will be described later, to move. It serves to be inserted easily, and through this, the fastening ring 20 can be easily moved vertically from the lower side to the upper side of the sleeve body 10.

Meanwhile, as shown in FIG. 1, the above-described sleeve body 1 is formed in a cylindrical shape with the upper and lower parts penetrating and the inside being hollow, and the upper end has a flap 13 extending horizontally inward toward the center. is formed And a cover 14 is provided inside the flap 13 to be detachable.

The above-described cover 14 is formed at the upper center of the slab body 10 so that it can be selectively removed. This prevents the pouring mortar from flowing into the slab body 10 by closing the inside of the slab body 10 during construction of the slab 30, and after the curing of the mortar is completed, the granular pipe is installed through the slab body 10. This is to ensure that it can be removed. This cover 14 may be detachably connected to the edge of the flap 13 through a perforation line, or may be detachably coupled to the side of the flap 13 through a separate detachment means.

And as shown in FIG. 2, after the cover 14 is removed, a separate clamp 15 may be installed on the upper side of the slab body 10 for the purpose of fixing the standing pipe.

In addition, a fastener 12 is formed horizontally connected to the top of the above-described insertion groove 11, and this fastener 12 is a fastening ring 20 moved vertically along the insertion groove 11 in a horizontal direction. It moves and fastens to fix its position. As shown in FIGS. 2 and 3, two of these fasteners 12 are formed at opposing points at 180-degree intervals among the four insertion grooves 11.

Additionally, a moving groove 16 may be further formed between the insertion groove 11 and the fastener 12. This moving groove 16 serves to guide the rotation of the insertion protrusion 25 moved vertically along the insertion groove 11 toward the fastener 12. That is, the insertion protrusion 25 is not inserted directly into the fastener 12 from the top of the insertion groove 11, but is moved along the moving groove 16 and then entered into the fastener 12, thereby ensuring smooth movement and coupling. making it possible. This moving groove 16 is formed horizontally at the top of the insertion groove 11, and a fastener 12 is connected to the end of this moving groove 16. The moving groove 16 may or may not be formed. Maybe not.

A fastening ring 20 is inserted and fixedly installed within the aforementioned sleeve body 10, and this fastening ring 20 allows the fireproof filler 24 provided therein to be firmly positioned within the sleeve body 10. It plays a role in making things happen.

This fastening ring 20 is formed in a ring structure of double partitions with an open top and a height, and the refractory filler 24 is accommodated therein. The fastening ring 20 is moved vertically along the insertion groove 11 on the outer periphery and is then connected to a fastener ( 12) An insertion protrusion 25, which is horizontally moved to the side and fastened, is formed to protrude.

The above-described insertion protrusions 25 are formed to protrude in two opposite directions at 180-degree intervals on the outer periphery of the fastening ring 20, and the upper edge of the tip of the insertion protrusions 25 has a moving groove ( 16) and the fastener 12, or is formed to be round so that it can be rotated horizontally toward the fastener 12.

That is, the insertion protrusion 25 is fastened in an interference fit manner within the fastener 12. When the upper end of the insertion protrusion 25 is formed at an angle, the moving groove 16 and the fastener ( 12), or because it cannot be easily rotated toward the fastener 12, the upper corner of the line in the direction in which the fastening ring 20 is fastened is formed to be rounded, thereby making it easier to rotate the insertion protrusion 25.

In addition, as this insertion protrusion 25 protrudes outward from the sleeve body 10 through the fastener 12, it can be hardened together with the concrete when the slab is hardened, so that the fastening ring 20 is inserted into the sleeve body 10. Enables it to be firmly fixed.

In addition, in order for the insertion protrusion 25 to be inserted into the fastener 12 and placed in a protruding position, the size of the fastener 12 must be slightly expanded compared to the insertion protrusion 25. In this case, the concrete is formed into the sleeve body ( 10) There is a risk of a small amount being introduced into the interior. To this end, the fastener 12 is formed to an optimal size so that the insertion protrusion 25 can be inserted in an interference fit manner. However, even if the insertion protrusion 25 is formed somewhat larger than the fastener 12, the fastener 12 ) It can be fastened to protrude outward, and can also be made of a synthetic rubber material with its own elasticity to prevent a gap between the insertion protrusion 25 and the fastener 12.

Meanwhile, a plurality of openings 23 are formed in the inner partition wall 22 of the fastening ring 20, which is formed in a double partition structure of the external partition wall 21 and the internal partition wall 22. These openings 23 are, As shown in FIG. 4, in the event of a fire, the fireproof filler 24 contained in the fastening ring 20 serves to induce expansion only to the inside of the sleeve body 10.

In this way, the above-mentioned fastening ring 20 has a double partition structure of the external partition 21 and the internal partition 22, and as the upper part is opened, the ring-shaped refractory filler 24 with a height is stably formed therein. The fire-resistant filler 24, which can be accommodated and at the same time expands during a fire, can only expand in the inner direction of the sleeve body 10 through the opening 23.

According to the penetrating sleeve having a fastening ring for fire-resistant filler as described above, it is provided within the penetrating sleeve to block the spread of fire in the event of a fire, but the fastening ring containing the fire-resistant filler is completely adhered to the penetrating sleeve and at the same time, an insert protrudes from the fastening ring. As the protrusion protrudes and fastens to the outside of the fastener formed on the through sleeve, the protruding insertion protrusion can be hardened integrally with the concrete, allowing the fastening ring to be firmly fixed and installed within the through sleeve, and is fire-resistant within the fastening ring formed with a double bulkhead structure. As the filler is firmly fixed, the fireproof filler expands stably in the event of a fire, and a number of openings are formed on the inner wall of the double bulkhead that allow the fireproof filler to expand only to the inside of the sleeve body in the event of a fire, resulting in a flame blocking effect. is outstanding.
