Description

Fixed device of pipe to prevent the fire and duct construct method using one

The present invention relates to the fixing device of the riser pipe to be constructed in a multi-storey building, and to the construction method of the pipe using the device, and to prevent fire spreading to take a more perfect fire to the floor after the construction of the riser pipe to the building. The construction of the fireproof sealant for preventing bleeding is to be made easily, so as not to cause the occurrence of defects, and also to be applicable to the granular pipe of various diameters.

At the present, the floor of multi-story buildings such as apartments or buildings are constructed so that the riser pipes for cold and hot facilities are penetrated up and down. In this case, however, the through sleeves constructed at this time are fixed to the through pipes by using a separate fixing device because the fitting is not accurately performed due to the difference in the diameters of the pipes.

However, since most of the fixing device is made of plastic, there is a risk of releasing harmful gases due to the nature of the plastic in case of fire.

Therefore, in recent years, it has been proposed to make a semicircular band body and a flange by using a metal plate to prepare for such a fire, but its disadvantage is that the band body is folded by a hinge element, so that the diameter of the granular pipe is different. In case of gap, fire and harmful gas from lower layer cannot be blocked in case of fire, and if the diameter of granular pipe and through sleeve does not match, it is difficult to construct, as well as difficulty of manufacturing and supply of hot water pipe for district heating. Due to the expansion and contraction of the insulation or cushioning is peeled off.

Also, preventive measures against fire bleeding have almost no problem when the pipe is made of metal pipe, but it is made of plastic so that all the pipes are burned out and lost due to fire. It can not be.

In particular, when a pipe is installed in a multi-storey building, since the insulation is filled in the space between the pipe and the through-sleeve, harmful gas generated during incineration of the insulation is also serious.

Therefore, in recent years, as a countermeasure against a more complete fire spreading, the fireproof sealant is expanded to a predetermined thickness by filling a fireproof sealant that is expanded about 5 to 30 times by a high temperature in case of fire to the upper layer of the thermal insulation material. By blocking the inside of the lost pipes, a fire sealant construction is performed to block the spread of fire to the upper floor.

However, since the construction of the fire prevention sealant is a separate addition after the construction of the cold and hot plumbing equipment, the fire protection seal is filled after separating the fixing device of the granular pipe fixed to the through slab for the construction of the fire prevention sealant. Since there is a difficulty in the construction work to fix the fixing device of the riser pipe again.

In addition, the insulation material is usually installed when the construction of cold and hot plumbing facilities, at which time most of the workers do not have any interest in the construction of the fireproof sealant, so the construction of the insulation material is carried out even if the construction of the fireproof sealant is required later. In many cases, there is little or no spare space to fill the sealant.

Therefore, in this state, it is not possible to expect a fire spreading effect because the filling of the fireproof sealant is not sufficient. Therefore, in order to install a fireproof sealant of sufficient thickness, it is necessary to remove a part of the thermal insulation material already filled and secure a space for the construction of the fireproof sealant. Since additional work is required, there are many difficulties in constructing a fire sealant.

Therefore, in the present invention, while the prevention measures against fire spreading is provided, the construction of the fireproof sealant is made of a structure that can be easily and simply injecting the fireproof sealant without removing the fixing device already installed. In addition, it is made of a structure that can be secured space for the filling of the fire-proof sealant that can be installed later in the construction, and also can be used for granular pipes of various diameters, ease of manufacture, ease of construction and separation of packing It is to be able to solve all the above-mentioned problems by providing a riser pipe fixing device made of a structure that can prevent the.

In addition, it is intended to facilitate the construction of the fire-proof sealant for preventing the spread of fire by installing the fixing device of the riser pipe during the construction of the pipe.

To this end, the granular pipe fixing device of the present invention includes a semicircular band body divided into equal parts, a flange formed in the middle of the band body, and formed on corresponding portions of both ends of the band body, so that tightening and coupling through tightening elements is provided. The contact surface formed and the overlapping wing which extends to the outer side of the contact surface, and which maintains airtightness by the overlapping are formed, and the fireproof sealant injection hole is formed in the flange so that the construction of the fireproof sealant through the injection hole is possible. The construction of the fireproof sealant for the fire preparation at the same time or to install the fireproof sealant without removing the pipe in the pipe construction state.

In addition, the bottom of the flange of the fixing device is to form a protrusion for securing the filling space of the fire sealant.

Therefore, the granular pipe fixing device of the present invention does not increase the flame or smoke when a fire occurs due to the overlapping wings formed inside the band body which is divided into equal parts. Since the separation of the packing is prevented inside the combined band body, the assembly is facilitated, and thus, it is possible to provide a low cost while preventing the spread of fire as well as the ease of construction work.

In addition, if a fire sealant injection hole is formed in the flange, it is necessary to install a fire sealant to prepare for fire, and install the fire sealant into the space between the through sleeve and the fixing device without disassembling the fixing device of the already installed granular pipe. This becomes possible and the fireproof sealant construction can be made easier and more convenient than before.

In addition, since the heat-insulating material filled in the space between the pipe and the through sleeve is pressed by the protrusion formed at the bottom of the flange of the fixing device, the space for filling the fireproof sealant is secured so that the fire protection effect can be sufficiently obtained. The sealant can be filled to obtain an excellent fire protection effect.
