Description

Fire piping installation structure {Fire piping structure for building}

The present invention relates to a fire-fighting piping installation structure. More specifically, the present invention relates to a fire-fighting piping installation structure, and more specifically, to allow each pipe to move a certain length in the longitudinal direction at the joint connecting the pipes, and to prevent fire caused by an external shock or earthquake from the outside. It relates to a fire-fighting piping installation structure that prevents the intrusion of flames, moisture, or various foreign substances, or poor connections.

In general, many people live or stay in apartment complexes such as high-rise apartments or residential-commercial complexes, so if a fire breaks out, there is a high possibility that not only property damage but also significant human damage will occur.

In recent years, as fire-related laws have been strengthened, apartment complexes have been required to install evacuation facilities that can quickly evacuate to the outside of the apartment complex in the event of a fire, or evacuation spaces that protect residents for a certain period of time while fire suppression and rescue operations are in progress. It is becoming mandatory.

In other words, it is mandatory for apartments over a certain size to be equipped with pipes or sprinkler devices to supply firefighting water, thereby minimizing damage in the event of a fire.

However, the reality is that in the case of apartments built before the revision of related laws or in small-scale apartments, the necessary measures are not taken to prevent fires, making it difficult to extinguish fires in the event of a fire.

The wet sprinkler device of Registered Patent No. 0434984 (2004.05.28.) has a fire extinguishing tank, a water pump, a water pipe, a sprinkler head, and a fire detector as its basic components, and the fire extinguishing tank is large enough to discharge fire water for a certain period of time. The technology is disclosed to form a water supply path from the water pump to the sprinkler head, with the water supply piping consisting of the primary side piping, the valve part, and the secondary side piping. Registered Patent No. 0500362 (June 30, 2005) .)'s household piping installation structure for sprinkler firefighting equipment in apartments is characterized by the arrangement of household piping in the ceiling slab that branches off from the standing pipe and connects to the sprinkler head from the sprinkler piping for the firefighting equipment of the apartment building, and branches off from the standing pipe. After connecting one household pipe to the branch pipe that acts as a distributor, it is branched into the required number of small diameter pipes and piped into the slab. By inserting the sprinkler household pipe into the protective pipe, the household pipe has a fire extinguishing function through the box and connecting accessories. By connecting this excellent sprinkler head, we are introducing a technology to install sprinkler fire extinguishing equipment without increasing the height between floors of the house.

However, the fire piping installation structure of an apartment complex for installing a conventional sprinkler device has the disadvantage of not being able to be self-installed after construction, so additional installation is not possible in apartment complexes such as old apartments where sprinkler devices are not installed.

In addition, in the method of reducing the floor height of an apartment complex and the sprinkler piping device used therein of Registered Patent No. 0431936 (2004.05.06.), the space for fire-fighting pipes installed in an apartment building is reduced, but when the fire-fighting pipes are damaged, There are problems that cannot be dealt with.

Below, with reference to the attached drawings, embodiments of the present invention will be described in detail so that those skilled in the art can easily implement the present invention.

The scope of rights of the present invention should not be construed as limited by the embodiments described in the text.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the description of the embodiments, the same reference numerals are assigned to the same components, and in some cases, descriptions of the same reference numerals are omitted.

Figure 1 is an separated perspective view illustrating the fire piping installation structure according to the present invention, and Figure 2 is a half cross-sectional view illustrating the combined structure of the fire piping installation structure according to the present invention.

As illustrated, the fire piping installation structure of the present invention consists of a pipe 10, a connecting pipe 20, a heat dissipation sheet 30, a heat-resistant pipe 40, a buffer member 50, and a finishing pipe 60.

Typically, buildings are equipped with plumbing pipes 10 of various materials and diameters through which various fluids such as liquids such as water or gases as well as electric wires pass.

To the pipes 10 provided in this way, a first O-ring 11 and a first stopper ring 12 are coupled to the outer peripheral surface of each end.

In particular, the first O-ring 11 is connected to the side end, the first stopper ring 12 is connected to the inside, and the first stopper ring 12 is formed smaller than the outer diameter of the first O-ring 11. It is more desirable to do so.

The connection pipe 20 is configured to allow fluid to flow between the pipes 10 by inserting one end of the pipe 10 from both sides. As shown in FIG. 3, the outer diameter of the pipe 10 is located in the middle of the length of the inner circumferential surface. The stopping protrusion 21 is formed so that a certain length protrudes inward with a smaller inner diameter, so that the ends of the pipes 10 inserted from both sides are always spaced apart by a certain length or more.

That is, the ends of each pipe 10 in the connection pipe 20 are not directly contacted.

The inner diameters on both sides of the connecting pipe 20, excluding the stopping protrusion 21, are formed to be larger than the outer diameter of the pipes 10, but are smaller than the outer diameter of the first O-ring 11 connected to the end of the pipe 10 and the first stopper. It is made to be larger than the outer diameter of the ring (12).

In addition, a second stopper ring 23 is coupled to the inner peripheral surface of both ends of the connection pipe 20 along with a second O-ring 22 that allows it to be in close contact with the outer peripheral surface of the pipes 10, and thus the second O-ring 22 ) is formed to be smaller than the outer diameter of the pipe 10, while the second stopper ring 23 is formed to have an inner diameter smaller than the outer diameter of the first stopper ring 11 connected to the pipe 10.

Therefore, the pipe 10 is connected to the inner and outer peripheral surfaces from both sides inside the connecting pipe 20 by the first O-ring 11 and the second O-ring 22 connected to the pipe 10 and the connecting pipe 20. It is movably inserted in close contact with the pipe, and the first stopper ring 12 and the second stopper ring 23 prevent the side end from being separated from the connection pipe 20.

The heat dissipation sheet 30 is attached to the outer peripheral surface of the connection pipe 20 where the end portion of the pipe 10 is partially inserted.

The heat dissipation sheet 30 may be formed in a band shape wound to cover the outer peripheral surface of the connection pipe 20, or may be formed in a tubular shape with the same length as the connection pipe 20.

The heat dissipation sheet 30 is provided to prevent heat from the outside due to fire, etc. from being transferred to the connection pipe 20.

A heat-resistant pipe 40 is connected to the outside of the heat dissipation sheet 30 with the same length as the connection pipe 20.

The heat-resistant pipe 40 is formed in a tubular shape using a heat-resistant material and is inserted and coupled to the outer peripheral surface of the heat dissipation sheet 30, so that high temperature heat generated by a fire transmitted from the outside is first transmitted before the heat dissipation sheet 30. Make sure it is blocked.

In particular, the heat dissipation sheet 30 between the connection pipe 20 and the heat-resistant pipe 40 allows the connection pipe 20 and the heat-resistant pipe 40 to be more closely adhered and coupled.

In this way, the connection structure of the connection pipe 20, the heat dissipation sheet 30, and the heat-resistant pipe 40 is such that the outside and both ends are covered by the buffer member 50.

The buffer member 50 has elasticity and both ends are in close contact with the outer circumferential surface of the pipe 10 to prevent moisture or other foreign substances from entering the inside of the connection pipe 20 from the outside and at the same time prevent the pipe 10 from the outside. To cushion the shock applied to the device.

In addition, the buffer member 50 is formed to be divided into a semicircle as shown in FIG. 4 and is separably coupled by fitting between the aligning protrusion 51 and the aligning groove 52 formed between the separated cross sections.

The buffer member 50 is made of foamed resin or silicone, but is not limited to this, and is more preferably made of strong heat resistance at high temperatures caused by fire.

The outside of the buffer member 50 is covered by a pair of pipe caps 60 from both sides.

That is, as shown in FIG. 7, the pipe cap 60 forms a through hole 61 larger than the outer diameter of the pipe 10 at both ends, and the ends facing each other in the middle of the length of the connection pipe 20 have a plan. The ground 62 is formed, and the seal ring 63 is inserted between the flange surfaces 62 on both sides facing each other.

The flange surfaces 62 and the seal ring 63 on both sides, which are formed to face each other, pass horizontally and are pressed together by fastening nuts and bolts.

Meanwhile, the tubular heat dissipation sheet 30 and the heat resistant pipe 40 provided to surround the outer peripheral surface of the connection pipe 20 are formed so that the middle portion of the length is separated from left to right as shown in FIG. 5, and each heat dissipation sheet 30 ) and the heat-resistant pipe 40 have assembly protrusions (31) (41) and assembly grooves (32) (42) formed on both opposing end surfaces to correspond to each other, so that these assembly protrusions (31) (41) are formed on both sides. It is custom-assembled and coupled to the assembly grooves (32) (42).

The actions and effects of the fire-fighting piping installation structure according to the present invention as described above will be described in more detail as follows.

The fire piping installation structure of the present invention is characterized by stably maintaining sealing properties and sealing force at the area connecting pipes 10 through which fluid flows.

In other words, in the present invention, the first O-ring 11 and the second O-ring 22 are formed at each end between the connection pipes 20 that connect the pipes 10, so that the main surfaces face each other. The connection pipe is movably connected in the longitudinal direction and is provided with a first stopper ring 12 and a second stopper ring 23 on the main surface adjacent to the first O-ring 11 and the second O-ring 22. The pipes (10) on both sides inserted into both sides of (20) are prevented from being separated.

That is, as shown in FIG. 6, the pipes 10 on both sides inserted from both sides inside the connection pipe 20 are maintained inside the connection pipe 20 even if flow occurs in the longitudinal direction due to an external shock or earthquake. By making a certain length movable, a stable connection state is maintained despite the flow of the pipes 10 due to external forces such as earthquakes, and at the same time, fluid can flow stably.

In addition, the outer circumferential surface of the connection pipe 20 is covered with a heat dissipation sheet 30 to block high temperature heat transmitted from the outside, and the outer circumferential surface of the heat dissipation sheet 30 is a heat-resistant pipe made of a heat-resistant material ( By surrounding the heat-resistant pipe 40 and the heat-dissipating sheet 30, the heat-blocking efficiency can be doubled by double insulation treatment.

In particular, the heat dissipation sheet 30 provides a close and solid connection between the connection pipe 20 and the heat-resistant pipe 40, thereby protecting the connection pipe 20 with more stable heat resistance and bonding force.

By covering the outside of the joint structure of the connection pipe 20, the heat dissipation sheet 30, and the heat-resistant pipe 40, which are combined in this way, with a buffer member 50, it has a buffering effect against external shocks, thereby enabling more stable facility maintenance. possible.

In particular, the buffer member 50 ensures that the ends are in close contact with the outer peripheral surface of each pipe 10, thereby completely blocking the inside and outside of the connecting pipe 20 from each other, thereby preventing flame, moisture, or other foreign substances from the outside. By blocking the inflow, the first O-ring (11) and the second O-ring (22) can be safely maintained.

On the other hand, the buffer member 50 is cut in the longitudinal direction and divided into semicircular shapes, and can be easily separated and joined by the aligning protrusion 51 and the aligning groove 52 formed along the dividing surface, so assembly is very easy. It can provide easy benefits.

The structure covered by the buffer member 50 is firmly covered by the pipe cap 60 on both sides.

The pipe cap 60 surrounds the pipe connection configuration on both sides and is attached to a bolt or nut with the seal ring 63 interposed between the flange surfaces 62 formed at mutually facing ends of the pair of pipe caps 60. Ensure that it can be firmly fastened.

In other words, there is a very useful effect of providing a firm fixing force while protecting the pipe connection components from external shock through the pair of pipe caps 60.

As such, the present invention is not limited to the described embodiments, and it is obvious to those skilled in the art that various modifications and changes can be made without departing from the spirit and scope of the present invention. Accordingly, such modifications or variations should be considered to fall within the scope of the claims of the present invention.
