The present invention relates to a pipe fixing material installed in a through hole of a building wall and a through hole space filling method by a pipe fixing material, and more particularly, a pipe generated when a through hole is formed in a wall of a building to penetrate a pipe. The gap between the through hole and the through hole can be fixed without additional taping work or fixing sleeve, and by the pipe fixing material and pipe fixing material installed in the through hole of the building wall to prevent the fire from being transmitted through the through hole in case of fire. A through hole space filling method.

Generally, in a building such as an apartment, various plumbing pipes are installed through walls. For example, wire pipes with various electric lines, including air conditioning cooling pipes and hot water boilers.

When the pipe is installed through the wall, a through hole is formed in the wall where the pipe is to be installed, and the pipe is installed through the through hole. At this time, a hole is formed in the wall to make the through hole. If the hole is formed in the concrete wall, its cut surface is not smooth, and there is a problem that is not fixed.

Therefore, the pipe is installed through the sleeve by installing the sleeve where the pipe will pass in advance.

In this way, when installing the sleeve or installing the pipe by drilling the through hole directly, the space between the through hole of the wall and the outside diameter of the pipe is generated, and the fireproof sheet is wound around the outer diameter of the pipe located in the through hole in the wall to fill the space. And, filling the space between the fireproof sheet and the through-hole fills the space. The refractory filler used here is glass wool, refractory mortar, silicone or urethane.

When the refractory filler is used to fill the space between the through-hole and the pipe, the process is complicated, and it is difficult to completely close the air, causing problems such as noise and heat loss due to the space.

And when the adhesive part of the refractory filler hardened by the fluctuation of the pipe opens, problems such as noise and heat loss are further exacerbated through the gap.

In addition, when the fire occurs, the pipe melts, and the refractory filler also flows down like a melted pipe or burns to some extent, so that a fire is transmitted through a through hole or a toxic gas is transmitted.

The present invention has been made to solve the problems described above, when the pipe is installed in the through-hole of the wall when the foam between the through-hole and the pipe is surrounded by the expandable refractory sheet layer and foam foam layer into the through-hole An object of the present invention is to provide a method of filling a space through a pipe fixing member and a pipe fixing member installed in a through hole of a building wall sealing the space between the pipe and the through hole while expanding the space.

According to the present invention, an expandable fireproof sheet layer is enclosed and fixed around a pipe of a portion where a through hole is located in a pipe inserted into a through hole of a wall, and a slow recovery foam is formed around the expandable fire resistant sheet layer. A foam foam layer having the properties of recovery foam is formed, and the foam foam layer is a flame retardant polyolefin open cell foam or a flame retardant foam open cell foam, and the foam foam layer and the expandable refractory sheet layer are joined by a water-soluble binder and a polymer adhesive. The pipe fixing material is installed in the through-hole of the building wall, characterized in that is fixed around the pipe. And a through hole forming step of forming a through hole through the pipe to penetrate the pipe. Securing the expandable refractory sheet layer around the pipe; Calculating a thickness and a foaming ratio of the foamed foam layer for calculating a distance and a foaming ratio of the foamed foam layer to be installed around the expandable refractory sheet layer after calculating a separation distance between the through hole and the expandable refractory sheet layer; Forming a foamed foam layer at a calculated foaming ratio and thickness with a water-soluble bider and a polymer adhesive around the expandable refractory sheet layer; In the pipe fixing material installed in the through-hole of the building wall comprising a; space-filling step of inserting the pipe formed with the expandable refractory sheet layer and the foam foam layer into the through-hole of the wall to expand the foam foam layer. It provides a through-hole space filling method.

Hereinafter, the configuration of the present invention will be described in detail with reference to the accompanying drawings.

The terms or words used in the present specification and claims should not be interpreted as being limited to the ordinary or dictionary meanings, and the inventors may appropriately define the concept of terms in order to best explain the invention of their own. Based on the principle, it should be interpreted as meaning and concept corresponding to the technical idea of the present invention.

The present invention forms a through-hole (2) for installing the pipe 10 of various uses in the wall (1), inserting the pipe 10 through the through-hole 2, but through-hole (2) of the pipe (10) The pipe fixing material is formed in this position. The pipe retainer consists of an expansion-resistant sheet and a foam that wraps around the expansion-resistant sheet.

Therefore, the pipe fixing material of the present invention is formed by surrounding the expandable refractory sheet layer 20 around the pipe 10 inserted into the through hole 2, as shown in Figure 2, The foam foam layer 30 is formed on the periphery.

The expandable refractory sheet layer 20 used in the present invention is made of a sheet-like thermal expansion refractory material that expands 10 times and expands when subjected to heat and exerts a heat insulating effect.

As a result, in the event of fire, the expandable refractory sheet layer 20 thermally expands to block the through hole 2.

The foam foam layer 30 formed to surround the expandable refractory sheet layer 20 uses a slow recovery foam that gradually expands over time, and includes a flame retardant polyolefin (PO Foam) open cell foam ( Open Cell Foam) and flame retardant foam open cell foam are used.

Thermoplastic olefin (TPO; Thermo Plastic Olefin) and thermoplastic elastomer (TPE) may be used for the flame retardant foam open cell foam.

Means for installing the foam foam layer 30 around the expandable refractory sheet layer 20 has a method of fixing to the expandable refractory sheet layer 20 by adhesive treatment to the slow recovery foam, and the expandable refractory sheet layer 20 and The foamed foam layer 30 is bonded by a water-soluble binder (urethane, acryl and other water-soluble adhesives) and a polymer adhesive to form a single product can be installed around the pipe 10.

When the pipe 10 is installed in the pipe 10 and calculates the separation distance between the through-hole (2) and then determined by calculating the thickness and foaming ratio of the foam foam layer 30 to be installed in the expandable refractory sheet layer 20.

Since the thickness and the expansion ratio of the foam foam layer 30 are different depending on the foam foam used, it is calculated by the calculation formula provided by the product.

Thermoplastic elastomers are thermally processable and can be said to be polymeric materials with the characteristics that the physical properties should have the properties of rubber by crosslinking. The polymer is composed of a polymer part having a glass transition temperature of 25 ° C or higher and a polymer of room temperature or lower, which acts as a physical crossking agent, and each of these parts is composed of a hard segment and a soft segment. segment), a thermoplastic elastomer can be produced by appropriately adjusting this component.

Thermoplastic elastomers (TPEs) have a lower specific gravity than thermoset rubbers, are easy to quality control, and can be used for high productivity processing equipment such as blow molding, which facilitates the design of various types of parts.

The thermoplastic elastomer exhibits rubber elasticity under use conditions, and is a polymer material which can be molded like thermoplastics under molding conditions. Like vulcanized rubber, the crosslinking process is unnecessary and can be reused. In the polymer chain of the heat-fired elastomer, there are elastic phase rubber components (soft phase) and crystal phases such as crystals or glass phase components which prevent plastic deformation in the vicinity of room temperature. Styrene-butadiene copolymer (SBR) is a representative example. In addition, there are PE, PP, polyester, polyurethane, polyamide and the like.

Foam foam layer 30 can be easily inserted into the through-hole (2) during the initial installation, and the foam foam layer 30 is expanded between the pipe 10 and the foam foam layer 30 as time passes in the inserted state The formed space 3 is hermetically filled.

Since the foam layer 30 fills the space part 3 in an airtight manner, it prevents initial smoke from being transmitted through the through hole 2 when noise or fire occurs.

And the fire continues to be generated to prevent the spread of the fire by a step as shown in FIG.

In general, since the through hole 2 is hermetically sealed, the initial smoke is not transmitted through the through hole 2 at the time of a fire, and if the fire is maintained without extinguishing, the pipe 10 melts and expands fire due to its heat. The sheet layer 20 expands to form the inflation portion 21.

When the expandable refractory sheet layer 20 is fully inflated, the expansion portion 21 blocks the through hole 2 to prevent the transfer of smoke and the spread of fire. Since the foam foam layer 30 is made of flame retardant, even if a fire occurs, toxic smoke is not transmitted because the gap is filled between the through-hole and the pipe.

The pipe fixing member installed in the through-hole of the building wall has an expandable fireproof sheet layer around the pipe 10 of the portion where the through-hole 2 is located in the pipe 10 inserted into the through-hole 2 of the wall 1. (20) is surrounded and fixed, the foam foam layer 30 having the properties of slow recovery foam (Slow Recovery Foam) is formed around the expandable refractory sheet layer 20, the method of achieving this is as follows .

First through the through-hole forming step (S1) to form a through hole 2 for penetrating the pipe 10 in the wall (1), and then to secure the expandable refractory sheet layer 20 around the pipe (10) After the step of fixing the expandable refractory sheet layer (S2), after calculating the separation distance of the space portion (3) formed between the through-hole (2) and the expandable refractory sheet layer 20, and around the expandable refractory sheet layer 20 The thickness of the foam foam layer to be installed and the expansion ratio of the foam foam layer and foaming magnification step (S3).

Next, the foamed foam layer 30 is fixed to the expanded foamed fireproof sheet layer 20 at a calculated expansion ratio and thickness with a water-soluble binder and a polymer adhesive, followed by a foamed foam layer forming step (S4). 20 is inserted into the through-holes 2 of the wall (1) and the pipe 10, the foam foam layer 30 is formed, the foam foam layer 30 is expanded to fill the space portion 3 is filled with space (S5) ), The pipe fixing member installed in the through hole of the present invention is completely installed.
