Description

Piercing sleeve unit

The present invention relates to a through-sleeve unit that is installed in a mounting hole formed on the floor or wall between floors of a building to provide a connection passage for pipes and close the mounting port of the building in case of a fire to reliably prevent the propagation of fire. .

In general, an internal space of a building is divided into a plurality of spaces by an interfloor floor and a wall, and a mounting hole through which various pipes can pass is formed in a frame of a building such as an interfloor floor or a wall. The mounting hole of the building frame is formed with a size larger than the width of the pipe, so that the pipe can pass through the mounting port even if there is a design error when installing the pipe.

However, as the mounting hole of the building frame is formed with a size larger than the width of the pipe, a gap is inevitably formed between the building frame and the pipe when installing the pipe. There is a problem of spreading the damage.

In order to solve this problem, it is currently legally compulsory to block the mounting part of the building frame, which can spread the fire in the event of a fire, with a fire-resistant material. Various materials are used as fire resistant materials that block the mounting hole of the building frame for pipe installation. In recent years, the use of a through sleeve combined with a fireproof foam material that can satisfy two purposes of pipe installation and fire spread prevention is increasing.

In general, the fire-resisting foam-integrated through sleeve includes a hollow through-sleeve inserted into a fitting formed on an interfloor floor or wall of a building, and a foamable fire-resistant foam material coupled to the through sleeve. This fire-resistant foam-integrated penetration sleeve provides a passage for a pipe installed to penetrate the floor or wall between floors, and in the event of a fire, the foamed fire-resistant foam material expands by heat and blocks the mounting hole, thereby preventing the spread of fire.

However, in the prior art, the flame is transferred to the inside of the through sleeve and the pipe (made of PVC material) inserted inside the through sleeve melts due to high temperature heat and is instantaneously joined with a part of the fireproof foam material that expands due to high temperature heat, so that the pipe and the pipe are connected. Part of the fire-resistance foam material fell downward at the same time, and in this case, a large problem occurred that the fire-resistant foam material could not properly close the fitting in case of a fire due to the fall and separation of a part of the fire-resistant foam material.

Therefore, the present applicant developed a supplementary structure that can additionally close the mounting port even if a part of the fire-resistant foam material falls and separates with the fall of the pipe as described above, thereby stably preventing the spread of fire through the mounting port. We propose a structure that can prevent

First, as shown in FIGS. 1 to 4 , the through sleeve 100 is made of a hollow structure having a sleeve through hole 110 on the inside, and is inserted into the mounting hole 20 of the floor slab 10 . do. In this way, the through sleeve 100 inserted into the mounting hole 20 is fixed to the formwork (not shown) before the concrete pouring operation for forming the floor slab 10, and is integrally fixed to the slab after concrete pouring. Since the bonding process is obvious to those skilled in the art, a detailed description thereof will be omitted.

1 to 4 , the through sleeve 100 is installed to penetrate vertically through the floor between floors of a building, and the first pipe 30 and the second pipe 40 are connected to the lower side of the through sleeve 100 and Each is connected to the upper side. The through sleeve 100 includes a sleeve body 120 , a cover block 140 , a flange portion 150 , and a sealing member 160 .

As shown in the related drawings prior to the detailed description of the through sleeve 100 , the fire-resisting foam unit 200 includes the first fire-resisting foam unit 210 and the first fire-resisting foam unit 200 disposed relatively adjacent to the first pipe 30 . It includes a second fire-resisting foam unit 220 that is spaced apart from the fire-resistance foam unit 210 , and the second fire-resistance foam unit 220 is spaced apart from the first fire-resistance foam unit 210 in the upper direction. In addition, the second fire-resistant foam member 220 is disposed at a position relatively closer to the inner central portion of the through sleeve 100 compared to the first fire-resistance foam member 210 . As shown in FIG. 1 , when the first pipe 30 and the second pipe 40 are installed in a vertical state, the sewage flowing into the second pipe is guided toward the first pipe 30 through the through sleeve 100 . .

First, the sleeve body 120 is formed in a hollow shape, and first and second fireproof foaming material insertion grooves 171 and 172 are provided so that the first and second fireproof foaming material parts 210 and 220 can be inserted, respectively.

Here, as shown in FIG. 1, the second fire-resistant foam material insertion groove 172 is provided at a position adjacent to the central region of the sleeve through-hole 110 relative to the first fire-resistant foam material insertion groove 171, and , The first fireproof foam material insertion groove 171 is formed by the first partition wall 181 , and the second fireproof foam material insertion groove 172 is also formed by the second partition wall 182 .

In the embodiment of the present invention, the first fireproof foaming material insertion groove 171 and the second fireproof foaming material insertion groove 172 are, respectively, on the side of the first fireproof foaming material portion 210 and the second fireproof foaming material portion 220 . It is formed by the ring-shaped first partition 181 and the second partition 182 formed to cover the .

In addition, a first pipe insertion groove 190 is provided in the sleeve body 120 so that the first pipe 30 can be inserted from the lower side to the upper side, and the first pipe insertion groove 190 is in the third partition wall 191 . is formed by

Here, the first to third partition walls 181 , 182 , and 191 are portions that melt or burn during the action of high temperature heat, and are preferably made as thin as possible so as not to interfere with the expansion of the first and second fireproof foam parts due to high temperature heat more than a certain amount.

Specifically, the first partition wall 181 and the second partition wall 182 forming the first fireproof foam part insertion groove and the second fireproof foam material part insertion groove may have a thickness of 1 to 5 mm, respectively. As the first partition wall 181 and the second partition wall 182 are formed to have the same thickness, they are heated by a flame generated in the event of a fire and are quickly removed and disappear, so that the first fire-resistant foam material part and the second fire-resistance foam part due to the high temperature heat The foam part expands quickly and does not interfere with closing the fitting.

Here, when the first partition wall 181 and the second partition wall 182 are less than 1 mm, molding defects of the first and second partition walls may occur in injection molding the through sleeve made of a plastic material, and when it exceeds 5 mm, high temperature Since it cannot be quickly melted and removed by the heat of the refractory foam, the rapid expansion and expansion of the first and second refractory foam parts may be partially limited, which may cause a disadvantage in that the propagation of flames and smoke cannot be quickly blocked.

In addition, the sleeve body 120 is provided with a seating protrusion on the inner circumferential surface so that the lower end of the second pipe 40 inserted from the upper side to the lower side is in contact with the seated state.

Next, the cover block 140 is inserted into the opening of the second fire resistant foam material insertion groove 172 to cover the second fire resistant foam material portion 220 .

In addition, the cover block 140 is made in a ring shape, and is fixed by being press-fitted into the second fireproof foam inserting groove 172, and the upper surface of which is the first pipe with sewage flowing into the second pipe and falling downward. It consists of an inclined surface having an angle of more than a certain degree so as to be smoothly guided inward. That is, the upper surface of the cover block 140 is provided to be inclined downward toward the inner central region of the sleeve body 120 .

Next, the flange portion 150 is interposed between the end of the sleeve body 120 and the second pipe 40 to finish the end, and between the end of the sleeve body 120 and the end of the second pipe 40 . By forcibly press-fitting the lower region of the second pipe 40 , it is possible to minimize the shaking of the end of the second pipe 40 .

In addition, as shown in Figures 1 to 4, the sleeve body 120, the flange portion 150, and the interconnection portion of the second pipe 40, a ring-shaped sealing member 160 for preventing leakage of sewage water. is interposed, and may be made of, for example, a material such as rubber, silicone, or epoxy.

In the embodiment of the present invention, a plurality of support protrusions 121 and a plurality of coupling portions 130 are provided on the lower outer surface of the sleeve body 120 .

A plurality of support protrusions 121 protrude from the side surface of the sleeve body 120 and are spaced apart from each other along the circumference. A fixing hole 122 into which fixing means such as nails or screws can be inserted is formed in the support protrusion 121 . When assembling the through sleeve 100 to the formwork, by inserting fixing means such as nails or screws into the fixing hole 122 and driving it into the formwork, the through sleeve 100 can be firmly fixed to the formwork.

The coupling part 130 includes a protruding part 131 and a protruding rib 132 protruding from a side surface of the sleeve body 120 , and the support member 300 is coupled to the protruding part 131 . That is, the support member 300 penetrates the protrusion 131 to enter the inside of the sleeve body 120 . Since the support member 300 penetrates the relatively thick protrusion 131 and is coupled to the sleeve body 120 , the coupling force between the support member 300 and the through sleeve 100 may be increased.

As shown in FIGS. 1 and 2 , the protrusion 131 has the sleeve body so that the support member 300 penetrates and the ends are inserted and fixed inside the first fire-resistant foam unit 210 and the second fire-resistance foam material unit 220 . It protrudes from the outer surface of 120 .

In the embodiment of the present invention, as shown in FIG. 2 , the protrusion groove 133 having a V-shaped cross-section is provided in the protrusion 131 . The support member 300 may pass through the protrusion 131 to pass through the protrusion groove 133 . In the process of coupling the support member 300 to the through sleeve 100 , when the end of the support member 300 is positioned in the protrusion groove 133 and the support member 300 is pressed toward the protrusion 131 , the support member 300 ) can reduce the problem of shaking. Accordingly, the support member 300 may be coupled to the through sleeve 100 by vertically penetrating the protrusion 131 without being obliquely embedded in the protrusion 131 . That is, the end of the support member 300 may be inserted and fixed to the inside of the first and second fireproof foam parts 210 and 220 through the pointed bottom portion of the protrusion groove 133 .

As shown in FIG. 2, the protruding ribs 132 protrude higher than the protrusions 131 on both sides of the protruding part 131, and in the space between the protruding ribs 132 spaced apart from each other, when pouring concrete for forming a floor slab Concrete is filled. The protrusion rib 132 may protect the support member 300 embedded in the protrusion 131 from both sides. That is, the protruding rib 132 can solve the problem that an external structure collides with the support member 300 during storage or transportation of the through sleeve unit 1000 , so that the coupling state of the support member 300 is released and detached.

A plurality of coupling portions 130 are arranged to be spaced apart along the circumference of the sleeve body 120 . Two of the plurality of coupling portions 130 are disposed adjacent to each other. The support member 300 embedded in the adjacent portions of both ends of the fire-resistant foam material portion 200 is coupled to the two coupling portions 130 disposed adjacent to each other. As will be described again below, the fire-resisting foam material part 200 bends the plate-shaped structure into a ring shape so that both ends face each other and inserts it into the through sleeve 100, and both ends of the fire-resistant foam material part 200 are As described above, it is fixed to the inside of the through sleeve 100 by the support member 300 , and at least one support member 300 is inserted for fixing the remaining parts as well.

The support protrusion 121 and the coupling part 130 are buried in the concrete when concrete is poured into the formwork while the through sleeve 100 is fixed to the formwork, thereby increasing the bonding force between the penetrating sleeve 100 and the floor slab 10. makes it

Next, the fire resistant foaming material part 200 expands when a fire occurs to close the mounting hole 20 of the floor slab 10 or the sleeve through hole 110 of the through sleeve 100 inside the through sleeve 100. In the embodiment of the present invention, in order to maximize the blocking performance of fire propagation, they are installed in multiple stages to be spaced apart from each other along the longitudinal direction of the through sleeve 100 .

Here, the through sleeve 100, like the first and second pipes 30 and 40, is made of a material that can be melted by high-temperature heat. Considering that, the closure of the mounting hole 20 of the floor slab 10 is more preferable than the closure of the sleeve through-hole 110 for the fire-resisting foam member 200 .

As shown in FIGS. 5 and 6 , the fire-resistant foam material part 200 includes a fire-resistant foam material 250 and a fire-resistant mesh body 260 , and the fire-resistant foam material 250 is a thermally expandable material that can be expanded by heat. is made of, and the fire-resistant mesh 260 is combined with a fire-resistant foam material, and is made of a heat-resistant material such as metal.

The fireproof foam unit 200 may block the mounting hole 20 of the floor slab 10 by expanding by receiving heat when a fire occurs. By shielding the refractory foam member 200 with the mounting port 20, the flow of flame or smoke through the mounting port of the floor slab is prevented and damage from fire can be reduced.

As shown in FIG. 3 , the fire resistant foam material part 200 has a substantially ring shape and is coupled to the through sleeve, and both ends of the fire resistant foam material portion having a long plate structure are bent to face each other to be coupled to the through sleeve. .

A fire resistant mesh 260 is coupled to one surface of the fire resistant foam 250 . The fire resistant mesh 260 is coupled to the fire resistant foam 250 so as to cover at least a portion of one surface of the fire resistant foam 250 . The fire resistant mesh body 260 is combined with the fire resistant foam material so that the fire resistant foam material 250 does not separate from the through sleeve 100 when the fire resistant foam material 250 is expanded by heating, and is made of a fire resistant material.

The fire resistant mesh 260 is made of a kind of mesh structure having a plurality of meshes, and may be made of various fire resistant materials having heat resistance above a certain level, such as metal or fire resistant fiber, and, for example, the fire resistant mesh may be made of a metal material.

The fire resistant mesh 260 may be made of a metal (including SUS) wire having a thickness of 0.1 to 0.6 mm.

In an embodiment of the present invention, the thickness (T) of the fire resistant mesh body 260 is preferably 0.1 to 0.6 mm so that the fire resistant foam material part 200 can be cut by a tool such as scissors. If the thickness of the fire resistant mesh 260 is less than 0.1mm, the fire resistant mesh 260 has a weak support force for supporting the fire resistant foam 250, so it is difficult for the fire resistant mesh 260 to smoothly function. On the other hand, when the thickness of the fire resistant mesh 260 exceeds 0.6 mm, the fire resistant mesh 260 is difficult to be cut by a tool such as scissors, and there is a problem in that price competitiveness is lowered.

The fire-resistant mesh 260 is made of a material that is not easily damaged by high-temperature heat and is combined with the fire-resistant foam 250, so that the fire-resistant foam is separated from the fire-resistant mesh while the fire-resistant foam expands due to the occurrence of a fire. It is possible to prevent separation from the through sleeve 100 without shielding the 20 .

In other words, the fire resistant mesh body 260 is coupled to the support member 300 so that the fire resistant foam material 250 expanded by heat does not separate from the through sleeve 100 and is fixed to the interlayer floor or wall by the support member 300 . By doing so, the fireproof foam 250 is supported.

Accordingly, when a fire occurs, the fireproof foam material 250 expands toward the inside of the mounting hole 20 of the floor slab 10 to close the mounting hole 20 and prevent the propagation of flame or smoke through the mounting hole 20 can be reliably blocked.

In an embodiment of the present invention, the fire-resistant foam material 250 and the fire-resistant mesh body 260 may be bonded to each other by, for example, a compression method. The refractory foam material 250 has a soft property that can be easily deformed in a high temperature environment. When the fire-resistant foam material is pressed against one surface of the fire-resistance foam material 250 while the fire-resistant foam material is soft, at least a portion of the fire-resistant foam material body 260 digs into the fire-resistant foam material and is buried in the fire-resistant foam material. Therefore, it is possible to combine the fire-resistant foam material 250 and the fire-resistant mesh body 260 without using a separate adhesive or fixing means.

As shown in FIG. 5 , the fire resistant foam material 250 and the fire resistant mesh body 260 are at least partially buried in the fire resistant foam material 250 so as to maintain a stable bonding state. It can be press-bonded. Preferably, the depth at which the fire resistant mesh 260 is buried in the fire resistant foam 250 is greater than the height at which the fire resistant mesh 260 protrudes from one surface of the fire resistant foam 250 for stable bonding between the fire resistant foam material and the fire resistant mesh. It is advantageous.

In addition, as shown in FIG. 6 , the fire resistant foam 250 and the fire resistant mesh 260 may be press-bonded so that the entire fire resistant mesh 260 is buried in the fire resistant foam 250 . In this case, when the fire resistant foam material 250 is cured, it completely covers the fire resistant mesh body 260 so that the fire resistant mesh body 260 is invisible from the outside of the fire resistant foam material 250, and the mutual bonding strength can be improved compared to the former. .

As shown in FIGS. 1 to 4 , in the embodiment of the present invention, fire propagation can be reliably prevented by installing the fire-resisting foam member 200 to be spaced apart from each other in multiple stages along the longitudinal direction of the through sleeve 100 .

In other words, as the flame is transmitted to the inside of the through sleeve 100 and the first pipe 30 inserted inside the through sleeve 100 is melted by the high temperature heat, it is disposed adjacent to the first pipe and expands due to the high temperature heat. 1 It is instantaneously joined to a part of the fireproof foam part 210 , and a phenomenon in which the first pipe 30 and a part of the first fireproof foam part 210 fall downward at the same time may occur. In this case, due to the fall and separation of a portion of the first fire-resisting foam unit 210 , a problem may occur that the first fire-resistance foam unit 210 does not properly close the fitting in case of a fire.

However, the present invention provides an additional second fire-resistance foam material part ( By providing 220), it is possible to reliably block the propagation of flame and smoke by securely shielding the mounting hole 20.

Here, the first to third partition walls 181 , 182 , and 191 are parts made of a plastic material, and are removed by melting or burning by high-temperature heat according to a fire, so that the expansion of the fire-resistant foam part is not hindered.

On the other hand, although the above description and related drawings have been illustrated and described based on the case in which the fireproof foam unit 200 is installed in two stages, it is of course not limited thereto and may be installed in three or more stages.

In the embodiment of the present invention, the fire resistant mesh body 260 is coupled to the support member 300 and fixed to the floor slab 10 by the support member 300, thereby supporting the fire resistant foam material 250 and eventually the fire resistant foam material. 250 may be secured to the floor slab 10 .

As shown in FIGS. 1 to 4 , the support member 300 is coupled to the through sleeve 100 to fix the plurality of fire resistant foam parts 200 to the inside of the through sleeve 100 , the through sleeve 100 . It is coupled to the side of the refractory foam material 200 serves to stably fix the floor slab (10).

In addition, the support member 300 has one end fixed to the floor or wall between floors of the building by pouring concrete, and the other end is fixed to the inside of the fireproof foam unit 200, so that the first and second ends are fixed to the interlayer floor or wall of the building. The fireproof foam parts 210 and 220 are fixed respectively.

The support member 300 is applicable as a screw made of a fireproof material such as metal, and is coupled to the through sleeve 100 so as to penetrate the side surface of the through sleeve 100 so that one end thereof protrudes to the outside of the through sleeve 100 and , the other end may be inserted into the fire-resistant foam material 200 to fix the fire-resistant foam material portion 200, or the length is extended to protrude toward the inner region of the mounting hole 20.

That is, one end of the support member 300 is embedded in the concrete floor slab 10 through a concrete pouring process for slab formation, and the other end is embedded in the fireproof foaming material part 200 located inside the through sleeve 100 . As a result, the fireproof foam part 200 may be fixedly coupled to the floor slab 10 .

The support member 300 is coupled to the through sleeve 100 in such a way as to penetrate from the outer surface of the through sleeve 100 to the inner side of the through sleeve 100 in a state in which the fire resistant foaming material part 200 is assembled inside the through sleeve 100, so that the fire resistant mesh body It may penetrate through the 260 and be embedded in the refractory foam 250 .

The support member 300 is coupled to the through sleeve 100 so as to penetrate the relatively thick protrusion 131 . As such, since the support member 300 penetrates a relatively thick portion of the side surface of the through sleeve 100 , the coupling force between the support member 300 and the through sleeve 100 can be increased, and the support member 300 is It is possible to reduce the problem that the through sleeve 100 is damaged in the process of coupling to the through sleeve 100 .

In addition, in the process in which the support member 300 is coupled to the fire resistant foam unit 200 , the first bulkhead 181 and the second bulkhead 182 are formed by the first fire resistant foam unit 210 and the second fire resistant foam unit 220 , respectively. ), by supporting the fire-resistant foam material portion in contact with one surface, the first fire-resistant foam material portion and the second fire-resistant foam material portion are pushed to the support member 300 by the fastening pressure and the sleeve body 120 is bent in the inward direction. No problem occurs.

Accordingly, while the support member 300 is inserted into the fire-resistance foam material part 200, the fire-resistant foam material 250 can maintain an upright posture, and the support member 300 is stably perpendicular to the fire-resistant foam material part 200. can be stuck

In the penetrating sleeve unit 1000 according to an embodiment of the present invention, in a state in which the support member 300 made of a fireproof material coupled to the through sleeve 100 is embedded in the floor slab 10, fireproof foaming inside the through sleeve 100 By being combined with the material 200 , the support member 300 can support the fireproof foam material 250 even if the through sleeve 100 is partially melted or burned due to heat generated during a fire.

Therefore, the fire-resistant foaming material part 200 expands from the inside of the mounting port 20 without being separated from the mounting port 20 of the floor slab 10, so that the mounting port 20 can be stably shielded, and the mounting port 20 ) can block the propagation of flames or smoke.
