Description

Vent of Architectural Prefabricated Joint}

The present invention relates to a prefabricated joint exhaust port for construction. More specifically, the lower flange surface and the upper flange surface formed at the upper and lower ends of the exhaust pipe body having a square cross-section are easily and quickly connected in the vertical direction between the exhaust pipe bodies, and are simple. This relates to a prefabricated joint exhaust port for construction that allows the exhaust pipe bodies to be firmly fixed simply by manipulating the operating protrusion.

In general, buildings are installed with exhaust vents that exhaust air to perform ventilation on each floor or in each household, and common exhaust vents are installed to exhaust air on multiple floors or multiple households together.

This common exhaust vent is installed in a vertically erected duct with a communication duct communicating with each floor or household, and exhaust is carried out through one connected duct.

However, since the common exhaust port is a single continuous duct standing vertically, there is a problem that the duct is easily damaged when an earthquake occurs or a shock occurs due to air discharge.

In the prefabricated common exhaust pipe for construction of Registered Patent No. 1820914 (January 22, 2018), a plurality of main exhaust pipes are combined in a one-touch method, and the auxiliary exhaust pipes connected to each main exhaust pipe are configured to be combined in a one-touch method.

Therefore, the auxiliary exhaust pipe can be easily separated from the main exhaust pipe to reduce the time and cost of replacement work, and by forming part of the main exhaust pipe and auxiliary exhaust pipe into a bellows-type corrugated pipe, the length can be freely adjusted and it can provide a buffering effect. It has the effect of allowing it to happen.

However, in the conventional prefabricated joint exhaust pipe for construction, the main exhaust pipe is formed in the shape of a circular pipe. However, not only can the rotational connection method not be applied to a pipe with a square cross section like a circular pipe, but also the connection between the upper and lower exhaust pipes requires bolts and nuts. Since it is done by fastening, there is an uneconomical problem in that the time and manpower required for the exhaust pipe installation work increases, increasing the work cost.

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 exploded perspective view illustrating the main configuration of the prefabricated common exhaust port for construction according to the present invention, and Figure 2 is an exploded cross-sectional view illustrating the main configuration of the prefabricated common exhaust port for construction according to the present invention.

As shown, the prefabricated cavity exhaust port for construction of the present invention is largely composed of an exhaust pipe main body 10, a stopper 20, a guide protrusion 30, a moving plate 40, and an elastic support means 50.

The exhaust pipe body 10 of the present invention has a square cross-section, and the upper and lower ends are bent horizontally to the same width to form flange surfaces 11 and 12.

That is, an upper flange surface 11 is formed at the upper end of the exhaust pipe body 10, a lower flange surface 12 is formed at the lower end, and the upper surface of the upper flange surface 11 has a certain height as shown in FIG. 3. A custom protrusion 13 is formed to curve upward while protruding upward.

The fitting protrusions 13 of the present invention are formed in plural pieces along the upper flange surface 11 on all sides, and the lower flange surface 12 has a matching protrusion 13 on the same vertical line as each fitting protrusion 13. The insertion tube portion 14 is formed so that the plate surface is opened downward and curved upward so as to be fitted.

Therefore, while connecting the different exhaust pipe bodies 10 vertically, the lower flange surface 12 of the upper exhaust pipe body 10 is placed on the upper flange surface 11 of the lower exhaust pipe body 10, so that the flange surface 11 ) (12) is brought into close contact with each other so that the fitting protrusion (13) is fitted into the interior of the insertion tube (14).

In this way, the upper exhaust pipe body 10 and the lower exhaust pipe body 10 are connected to each other by combining the upper and lower flange surfaces 11 and 12 with the fitting protrusion 13 and the insertion pipe portion 14. It is combined to prevent flow to.

In order to prevent upward and downward flow as well as lateral flow between the exhaust pipe main body 10, a stopper 20, a guide protrusion 30, a moving plate 40, and an elastic support means 50 are formed.

As shown in Figure 4, the catch 20 of the present invention has a moving hole 16 that vertically penetrates the plate surface of the upper flange surface 11 and a through hole 15 formed in the upper lower flange surface 12. It is formed at a height that penetrates vertically, and the upper end of the catch 20 is bent horizontally for a certain length to form a bent end 21, and the lower end extending downwardly through the moving hole 16 has a moving hole. The assembly protrusion 22 is formed in the longitudinal direction of (16) with a length greater than the width of the moving hole (16).

A guide protrusion 30 is formed on the lower periphery of the moving hole 16 of the lower flange surface 12 through which the catch 20 passes, so that the lower surface of the lower flange surface 12 protrudes downward at a certain height or more.

The guide protrusion 30 is shaped so that the protruding surfaces formed on both sides have a height difference and are connected while being inclined between the protruding surfaces having the height difference. Both ends of the guide protrusion 30 are configured to protrude further downward than the protruding surfaces. A departure prevention bump 31 is formed.

These guide protrusions 30 are formed along the lower periphery of the moving hole 16 to enable the latch 20 to move horizontally a certain length, and extend a certain length further to one side than the end of the moving hole 16. do.

The guide protrusion 30 has a shape that protrudes downward from the locking position to the highest height while the latch 20 has the lowest height in the unlocking position and slopes downward toward the locking position.

At the bottom of the catch 20 extending downward from the lower flange surface 12, the moving plate 40 is slide-coupled to the assembly protrusion 22 from the outside of the plate surface.

The moving plate 40 is formed to be larger than the size of the moving hole 16 so that the latch 20 does not escape from the upper part of the lower flange surface 12, and has an assembly protrusion 22 formed at the lower end of the latch 20. By custom-assembling it, the latch 20 is stably supported, and a certain height is protruded downward from the surface of the movable plate 40 or bent downward so that the movable plate 40 can be slid by hand or pushed. An operating protrusion 41 that allows pulling is provided.

Accordingly, while the moving plate 40 is made of a horizontal flat plate, the operating protrusion 41 is formed perpendicular to the moving plate 40 so that it can be operated by hand without a separate tool.

Meanwhile, an elastic support means (50) consisting of a spring holder (51) and a spring (52) axially coupled to the catch (20) is provided between the guide protrusion (30) and the moving plate (40).

The elastic support means (50) is in close contact with the lower surface of the guide protrusion (30), and the spring holder (51) supported by the latch (20) moves simultaneously when the latch (20) moves along the moving hole (16). It is raised and lowered along the lower surface of the guide protrusion 30, and the spring 52 is supported on the catch 20 between the spring holder 51 and the moving plate 40, and the spring holder 51 is supported by the guide protrusion ( 30), and at the same time, the moving plate 40 can flexibly rise and fall to a certain height.

Due to the elastic force of the spring 52, the moving plate 40 is always pressed downward and elastically, so that the bent end 21 formed at the top of the stopper 20 to which the moving plate 40 is connected is always on the lower flange surface. Make sure it is in close contact with the upper surface of (12).

Meanwhile, in the configuration of the present invention, the bent end 21 at the top of the catch 20 has a cross section of the protruding end inclined downward toward the vertical catch 20 from the top to the bottom, thereby forming the through hole 15 of the lower flange surface 11. It slides on the main surface to enable smooth upward movement, and the spring 52 installed on the stopper 20 can be a coil spring as shown in the drawing, but can also be a leaf spring.

In particular, a gasket (not shown) made of a heat-resistant material along with a seal is inserted between the upper flange surface 11 and the lower flange surface 12 of the upper exhaust pipe body 10 and the lower exhaust pipe body 10. It is more desirable.

As in the above-mentioned configuration, the action and effect of the prefabricated common exhaust port for construction according to the present invention will be examined in more detail as follows.

The present invention allows exhaust pipes having a square cross-section to be connected vertically along a common exhaust port. For this purpose, each exhaust pipe body 10 has a horizontal upper flange surface 11 and a lower flange surface integrally at the upper and lower ends. (12) is formed.

Therefore, when connecting the exhaust pipes in the vertical direction, the lower exhaust pipe and the upper exhaust pipe are connected by close contact between the flange surfaces (11) and (12).

However, a custom protrusion 13 is formed to protrude upward on the upper flange surface 11 of the exhaust pipe body 10, and an insertion pipe portion 14 is formed with a corresponding size on the lower flange surface 12. When connecting the exhaust pipe bodies 10, these fitting protrusions 13 are fitted and coupled to the insertion pipe portion 14 so that the exhaust pipe bodies 10 are connected exactly on the same vertical line.

The coupling between the fitting protrusion 13 and the insertion pipe portion 14 allows the upper flange surface 11 and the lower flange surface 12 of the exhaust pipe body 10 to be connected very easily and accurately.

If the exhaust pipe bodies 10 are vertically connected in this way, the area where the stopper 20 is provided passes through the moving hole 16 of the upper flange surface 11, and the bent end 21 located at the upper part as shown in FIG. 5 ) is located in the through hole 15 formed in the lower flange portion 12.

At this time, the spring holder 51 supported by the latch 20 is in close contact with the departure prevention protrusion 31 on one end of the guide protrusion 30, and in this state, the operating protrusion 41 is pressed upward as shown in FIG. 6. When this happens, the spring 52 contracts and moves the latch 20 upward to a certain height. At this time, the bent end 21 of the upper end of the latch 20 is raised to the upper part of the through hole 15 of the lower flange surface 12. It becomes a state.

In this way, when the manipulation protrusion 41 is pressed upward and continuously moved in one direction as shown in FIG. 7, the spring holder 51 in close contact with the guide protrusion 30 moves in one direction along with the stopper 20. The moment it moves along the inclined surface of (30), the end of the bent end (21) moves simultaneously at the upper part of the moving hole (16), and the spring (52) is further compressed along the upper surface of the lower flange surface (12). It moves.

When the spring holder 51 is positioned on the protruding surface most downwardly protruding from the inclined surface of the guide protrusion 30 due to the horizontal movement of the operating protrusion 41, the latch 20 moves downward due to the expansion force of the spring 52. As a result, it comes into close contact with the upper surface of the lower flange surface 12 of the upper exhaust pipe main body 10.

In this state, continue to push the operating protrusion 41 in one direction so that the latch 20 contacts the end of the moving hole 16 or the spring holder 51 contacts the departure prevention protrusion 31 on the other side as shown in FIG. 8. The bent end 21 of the catch 20 is pressed downward by the expansion force of the lower surface spring 52, and is tightly compressed on the upper surface of the lower flange surface 12, and the upper flange surface 11 of the lower exhaust pipe main body 10 and Ensure that the upper flange surface (11) of the upper exhaust pipe body (10) is firmly fixed.

In this way, when each operating projection 41 provided in all directions on the upper flange surface 11 of the lower exhaust pipe main body 10 is sequentially pushed upward and moved in one direction, the lower exhaust pipe main body 10 and the upper exhaust pipe main body ( 10) can be fixed very simply.

If the exhaust pipe is installed by continuously connecting the exhaust pipe bodies 10 in this manner, the labor cost as well as the installation time can be significantly reduced.

In particular, in the configuration of the present invention, there is no operating structure on the upper part of the lower flange surface 12 of each exhaust pipe body 10 other than the bent end 21 that is in close contact with the upper surface of the lower flange surface 12, so the coupling state is stable. There is also the advantage of being able to maintain it more cleanly while keeping it clean.

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.
