Description

Plumbing hanger{HANGER FOR PIPE}

The present invention relates to a hanger for piping, and more particularly, to a hanger for piping that is easy to install and disassemble and that the support state of the piping is stably maintained.

Various piping such as gas piping, water and sewage piping, air conditioning and heating piping, and various electrical and communication related piping are installed in industrial facilities and buildings. These pipes extend from one location to another along the ceiling of the building.

When a pipe having a long length and load is moved along the ceiling, deflection may occur or may be disengaged by wind. In order to prevent the sagging and separation of the piping, a plurality of hangers for piping are installed at regular intervals on the ceiling, and piping is mounted inside the hangers for piping, so that the piping maintains its initial installed condition and position.

Examples of such conventional piping hangers are disclosed in Patent Registration No. 1125262, Patent Publication No. 2014-0090061, Registration Practice No. 0421489, Registration Patent No. 1166441, Registration Practice No. 0343998, Publication Practice No. 2013-0003379, etc. have.

The installation work of the piping hanger is carried out by the worker moving to the ceiling side using a ladder or the like. In the conventional pipe hanger, a pair of clamps can be closed or opened in a hinged structure, wrapped around the outside of the pipe, or separated from the pipe. Here, any one of the pair of clamps is fixed to the anchor bolt provided vertically below the ceiling.

However, the disclosed conventional hanger for piping has a large disadvantage in that the fixing structure for fixing a pair of clamps to each other while the piping is accommodated therein is complicated, and thus the physical burden of the worker who has to lift the head toward the ceiling and work is large. there was.

In addition, the conventional hanger for plumbing has a disadvantage that when the user hits the top or bottom of a pair of clamps by hand during installation, the binding force between each other is weak and easily opened. If it is opened like this, the installation work has to be performed repeatedly, which increases the work fatigue of the worker.

In addition, in the conventional piping hanger, the coupling state between the pair of clamps may be naturally released due to the weight or load of the piping. When the hanger for piping is opened in this way, there is a risk that the position of the piping is displaced or falls to the bottom, causing a safety accident.

The object of the present invention is to solve the above-mentioned problems, and to provide a hanger for piping that can be easily installed and disassembled.

Another object of the present invention is to provide a hanger for piping that can be stably maintained even in an impact applied during installation.

Another object of the present invention is to provide a pipe hanger that can maintain a stable support state of the pipe even if the time is cured after installation.

The above objects and various advantages of the present invention will become more apparent from preferred embodiments of the present invention by those skilled in the art.

The present invention is a means for achieving the above object, the upper end is coupled to the anchor bolt (B) provided perpendicular to the ceiling, the fixed section including a fixed clamp body 111 surrounding a semicircle on one side of a circular pipe A clamp 110; Rotating clamp (110) that is rotatably coupled to the fixed clamp (110) and includes a bracket coupling end (123) formed with an elastic member receiving hole (124) on the upper side of the pivoting clamp body (121) surrounding the other half of the pipe ( 120) and; It is coupled to the upper portion of the rotational clamp 120, elastically stretched and compressed, and includes an elastic opening and closing member 130 that allows the upper end of the rotational clamp 120 to be coupled to or disengaged from the fixed clamp 110, , The elastic opening and closing member 130 is accommodated in the elastic member receiving hole 124, the rotating clamp body 121 and the fixed clamp body 111 is closed to surround the entire outer circumference of the cross section of the pipe (A) When the rotation clamp body 121 is rotated in a state, the coupling bracket 116 is inserted into the upper portion of the elastic member receiving hole 124, it is characterized in that the coupling with the elastic opening and closing member 130.

In addition, the fixed clamp 110, the fixed clamp body 111 surrounding the outer periphery of one side of the pipe in a semi-circular shape; An anchor bolt fixing plate 113 formed horizontally on the upper end of the fixed clamp body 111, and equipped with a nut 114 to which the anchor bolt B is coupled; A rotating clamp coupling end 117 provided at a lower end of the fixed clamp body 111 and supporting the rotating clamp 120 so that the rotating clamp 120 rotates; The fixed clamp body 111 is formed to extend horizontally toward the rotational clamp 120 at the end, and includes a coupling bracket 116 through which an inclined protrusion fastening hole 116a is formed on the plate surface, and the rotational clamp 120 ), the fixed clamp body 111 and the semi-circular rotation clamp body 121 in the direction opposite to the; Characterized in that it comprises a coupling end insertion hole 126 into which the rotation clamp coupling end 117 is inserted.

In addition, the elastic opening and closing member 130 is formed to be bent up and down, compressed and extended by an external force, and received by the elastic member receiving hole 124 and a leaf spring 131; The plate spring 131 is formed to extend horizontally to the top, and when the plate spring 131 is extended upward in the closed state, it is inserted into the inclined protrusion fastening hole 116a of the coupling bracket 116 to close the plate. It characterized in that it comprises a horizontal engaging surface 133 is provided with an inclined projection (133a) for applying a restraining force to maintain the state.

In addition, the upper end of the bracket coupling end 123 is provided with a coupling rib 123a horizontally projected toward the fixed clamp 110, the end of the anchor bolt fixing plate 113 in contact with the bracket coupling end 123 In the closed state, a pipe hanger characterized in that the rib insertion hole 115a into which the coupling rib 123a is inserted is formed.

In the hanger for piping according to the present invention, the rotating clamp can be fixed to the fixed clamp while the inclined protrusion elastically descends and rises by only one operation in which the rotating clamp is pushed in the direction in which the operator closes the fixed clamp.

In addition, when the rotating clamp is fixed to the fixed clamp, it is not only engaged by an inclined protrusion, but also the upper and lower positions are constrained by cross-insertion of the coupling ribs and the coupling brackets of the bracket coupling ends in the opposite directions from above and below. Alternatively, even when an impact is applied from the bottom, the bonding state may be stably maintained.

In addition, even when the hanger for the piping in the closed state is switched to the open state, only the operation of the operator pressing the handle down is required.

Accordingly, the work flow for installing and disassembling the worker's piping hanger is significantly reduced, thereby reducing the physical burden of the worker and reducing the time required for installation and disassembly.

In addition, since the elastic force is applied in the direction in which the plate spring extends, the inclined protrusion is stably inserted into the inclined protrusion fastening hole unless a force is applied to the lower portion. Thereby, the support state of the pipe hanger can be stably maintained even after a time has elapsed after the installation work.

The embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be interpreted as being limited to the embodiments described in detail below. This embodiment is provided to more fully explain the present invention to those skilled in the art. Therefore, the shape of the elements in the drawings may be exaggerated to emphasize a clearer description. It should be noted that in each drawing, the same members may be indicated by the same reference numerals. Detailed descriptions of well-known functions and configurations that are determined to unnecessarily obscure the subject matter of the present invention are omitted.

1 is an exemplary view showing a state in which the hanger 100 for piping according to the present invention is installed on a ceiling to support the piping (A).

As shown in the drawing, the hanger 100 for piping according to the present invention is fixedly coupled to the anchor bolt (B) provided perpendicular to the ceiling and the fixed clamp 110 and the fixed clamp 110 is rotatably coupled to the fixed clamp It includes a rotating clamp 120 that is opened and closed at 110, and an elastic opening and closing member 130 coupled to the rotating clamp 120 to couple or disengage the rotating clamp 120 and the fixed clamp 110.

The hanger for piping 100 of the present invention is rotated by the elastic force of the elastic opening/closing member 130 so that the worker rotates the rotating clamp 120 in the direction in which it is closed to the fixed clamp 110, the rotating clamp 120 is fixed clamp ( It is coupled in a closed state to 110), it can be switched to the open state by separating the rotating clamp 120 from the fixed clamp 110 only by pressing the elastic opening and closing member 130 in the downward direction.

Accordingly, the worker's work flow and working time can be significantly shortened, and the rotating clamp 120 and the fixed clamp 110 are stably maintained by the elastic force of the elastic opening and closing member 130. have.

Prior to the description, the open state refers to a state in which the upper end of the rotating clamp 120 is separated from the upper end of the fixed clamp 110, as shown in FIG. 6(a), and the closed state of FIGS. 2 and 6 ( As shown in c), the upper end of the rotating clamp 120 refers to a state coupled to the upper end of the fixed clamp 110. In the open state, the pipe A is inserted or removed between the fixed clamp 110 and the rotating clamp 120, and the pipe A is supported in the fixed state.

Figure 2 is a perspective view showing the configuration of the closed state of the pipe hanger 100, Figure 3 is an exploded perspective view showing an exploded view of the configuration of the pipe hanger 100.

In the hanger 100 for piping, the fixed clamp 110 and the rotating clamp 120 surround the outer circumference of the pipe A to support the pipe A. The pipe A is usually formed in a circular cross section. Accordingly, the fixed clamp 110 and the rotating clamp 120 are respectively formed in a semicircle shape corresponding to this.

However, this is only an example, and in some cases, when the cross section of the pipe A is rectangular or polygonal, the fixed clamp 110 and the rotating clamp 120 may be formed in a shape corresponding to half the shape of the cross section.

The fixed clamp 110 is fixedly coupled to the anchor bolt (B) fixedly installed on the ceiling, as shown in Figure 1 so that the position of the pipe hanger 100 is fixed to the ceiling.

The fixed clamp 110 is formed to extend to the top of the fixed clamp body 111 and the fixed clamp body 111 surrounding one side outer periphery with respect to the cross-sectional shape of the pipe (A) in a semi-shape shape as shown in FIG. Anchor bolt fixing plate 113, a nut 114 fixed to the anchor bolt fixing plate 113 and engaged with the anchor bolt (B), and a vertical support plate 115 formed perpendicular to the anchor bolt fixing plate 113, and vertically It includes a coupling bracket 116 formed to protrude horizontally on the support plate 115 and coupled to the elastic opening and closing member 130.

The fixed clamp body 111 is formed by bending in a semicircle shape with a plate-like material having a certain width. The inner diameter of the fixed clamp body 111 corresponds to the outer diameter of the pipe (A) as shown in FIG. 1 or is formed to have a large length. Thereby, the pipe A is accommodated and supported in a circle formed by the fixed clamp 110 and the rotating clamp 120.

A plurality of first lightweight holes 112 are formed on the plate surface of the fixed clamp body 111. The first lightweight hole 112 serves to reduce the weight of the fixed clamp body 111.

The upper end of the fixed clamp body 111 is connected to the connecting plate 113a of the anchor bolt fixing plate 113, and the lower end is connected to the rotating clamp coupling end 117. The fixed clamp 110 is manufactured integrally with the exception of the nut 114.

The hanger 100 for piping of the present invention is installed at regular intervals along a path where the pipe (A) is moved to the ceiling to support the pipe (A) to prevent sagging and departure of the pipe (A). Accordingly, the fixed clamp body 111 is designed with a material, thickness, and width that can sufficiently bear the weight of the pipe (A). Depending on the purpose and type of use of the pipe (A), the standard of the fixed clamp body 111 may be changed differently.

The anchor bolt fixing plate 113 is horizontally formed on the upper portion of the fixing clamp body 111 and is coupled with the nut 114. The anchor bolt fixing plate 113 is extended to the fixed clamp body 111 by the connecting plate 113a. In the center region of the anchor bolt fixing plate 113, the nut 114 is fixed by welding. The nut 114 is screwed to the anchor bolt B fixed to the ceiling as shown in FIG. 1 to fix the position of the hanger 100 for piping.

The operator arranges the nut 114 of the anchor bolt fixing plate 113 to be coaxial with the anchor bolt B for installation of the pipe hanger 100, and rotates the anchor bolt fixing plate 113 to rotate the nut 114 ) To the anchor bolt (B).

The vertical support plate 115 is formed to extend vertically downward in the end portion of the anchor bolt fixing plate 113. The vertical support plate 115 contacts and supports the bracket coupling end 123 of the rotational clamp 120 to limit the maximum rotational angle of the rotational clamp 120.

A rib insertion hole 115a is formed through the boundary region between the vertical support plate 115 and the anchor bolt fixing plate 113. When the rotating clamp 120 is closed, the rib inserting hole 115a is inserted with a coupling rib 123a formed at the bracket coupling end 123 of the rotating clamp 120.

As the coupling rib 123a is inserted into the rib insertion hole 115a, the rotation clamp 120 can be coupled to the fixed clamp 110 in an accurate position without being distorted. The rib insertion hole 115a is formed through an area corresponding to the width and height of the coupling rib 123a.

The coupling bracket 116 is formed to protrude in the horizontal direction toward the rotation clamp 120 at the bottom of the vertical support plate 115. When the rotation bracket 120 is closed, the coupling bracket 116 is inserted into the elastic member receiving hole 124 of the bracket coupling end 123 and coupled with the elastic opening and closing member 130. The closed state of the fixed clamp 110 and the rotating clamp 120 may be constrained by a process in which the coupling bracket 116 is coupled with the elastic opening and closing member 130.

Inside the coupling bracket 116, the inclined protrusion fastening hole 116a into which the inclined protrusion 133a of the elastic opening/closing member 130 is inserted is formed. 2, the inclined protrusion 133a of the elastic opening and closing member 130 is inserted into the inclined protrusion fastening hole 116a. The inclined protrusion 133a is inserted into the inclined protrusion fastening hole 116a so that the position of the coupling bracket 116 is fixed to the elastic opening/closing member 130. Thereby, the closed state of the pipe hanger 100 can be stably maintained.

The front end 116b of the coupling bracket 116 is formed in a trapezoidal shape with both sides cut inward to facilitate insertion into the elastic member receiving hole 124. That is, the width W2 of the tip 116b is formed to be narrower than the width W1 of the coupling bracket 116, so that it can be easily inserted into the elastic member receiving hole 124.

The rotating clamp coupling end 117 is coupled to the coupling end insertion hole 126 of the rotating clamp 120 to support the rotating clamp 120 to rotate relative to the fixed clamp 110.

In the conventional piping hanger, a pair of clamps are operated by a hinge. However, there is a problem in that the closed state is released as the hinge is deformed by the weight of the pipe.

Accordingly, the piping hanger 100 of the present invention allows the coupling state to be stably maintained even when a load of the piping is applied by physical coupling of the rotating clamp coupling end 117 and the coupling end insertion hole 126 without a hinge. .

Rotating clamp coupling end 117 is formed by bending from the bottom of the fixed clamp body 111 and is coupled to the end of the connecting bending arm 117a and the connecting bending arm 117a inserted into the coupling end insertion hole 126 It includes a rotation support wing (117b) overlapping the coupling end insertion hole (126).

As shown in Figure 5, the connecting bending arm 117a is horizontally extended from the bottom of the fixed clamp body 111 and then bent inward at a certain angle to be inserted into the coupling end insertion hole 126 of the rotating clamp 120 do. Then, the rotation support wing 117b overlaps the rotation clamp body 121 inside the coupling end insertion hole 126, and serves as a rotation shaft so that the rotation clamp 120 rotates.

The width W4 of the rotation support wing 117b is formed wider than the width W3 of the connecting bending arm 117a. In addition, the width W8 of the coupling end insertion hole 126 is formed larger than the width W3 of the connecting bending arm 117a and narrower than the width W4 of the pivoting support wing 117b.

When assembling the pipe hanger 100, the operator inclines the rotation clamp 120 to insert the rotation support wing 117b into the coupling end insertion hole 126. When the rotation support wing 117b is inserted into the inside of the rotation clamp body 121, the width of the rotation support wing 117b is narrower than the width of the coupling end insertion hole 126 so that it does not deviate to the outside.

At this time, the coupling slit 126a is formed at a certain length in the vertical direction on the upper portion of the coupling end insertion hole 126 so that the rotation support wing 117b can be easily inserted into the coupling end insertion hole 126.

6(a), when the rotation clamp coupling end 117 is inserted into the coupling end insertion hole 126, the rotation clamp as shown in FIGS. 6(b) and 6(c) 120 may be rotated around the pivot support wing (117b). At this time, the maximum opening angle of the rotating clamp 120 can be adjusted by the inclination angle of the connecting bending arm (117a).

The rotating clamp 120 is rotated to the fixed clamp 110 and the hanger 100 for piping is switched to a closed or open state and supports or separates the piping (A).

The rotating clamp 120 is provided with a rotating clamp body 121 having a semi-circular shape in a direction opposite to the fixed clamp body 111 and a bracket clamp coupled to the coupling bracket 116 provided on the upper end of the rotating clamp body 121 Column 123 is included.

The rotating clamp body 121 is formed in a semicircle shape surrounding the outer periphery of the pipe (A). The rotating clamp body 121 is formed to have the same outer diameter as the fixed clamp body 111. At least one second lightweight hole 122 is formed on the plate surface of the rotating clamp body 121.

The upper end of the rotating clamp body 121 is integrally connected to the bracket coupling end 123. The coupling end insertion hole 126 described above is formed through the lower end of the rotational clamp body 121 so that the rotational clamp body 121 can be rotated to the rotational clamp coupling end 117.

The bracket coupling end 123 is provided vertically on the upper end of the rotating clamp body 121, accommodates the elastic opening and closing member 130 therein, and is detachably coupled to the coupling bracket 116. The bracket coupling end 123 is formed in an area that can be supported in contact with the vertical support plate 115 in a closed state. The upper end of the bracket coupling end 123 is provided with a coupling rib 123a protruding toward the coupling bracket 116.

The coupling rib 123a is inserted into the rib insertion hole 115a of the vertical support plate 115 to guide the coupling direction when the rotation clamp 120 is closed to the fixed clamp 110. In addition, as the coupling rib 123a is inserted into the rib insertion hole 115a and the position is constrained up and down, the coupling state can be stably maintained even when an external impact is applied during the installation work of the hanger 100 for piping. .

An elastic member-receiving hole 124 is formed through a certain area inside the coupling rib 123a.

4 is a perspective view showing a state in which the elastic opening and closing member 130 is coupled to the rotational clamp 120, and FIG. 5 is a cross-sectional view showing the cross-sectional configuration of the pipe hanger 100 in a closed state. 3 to 5, the elastic member receiving hole 130 is accommodated in the elastic member receiving hole 124, and when the rotation clamp 120 is coupled to the fixed clamp 110, the upper portion of the elastic opening and closing member 130 Furnace coupling bracket 116 is inserted.

The elastic member receiving hole 124 is formed with an area in which the plate spring 131 of the elastic opening and closing member 130 can be accommodated at a certain height (h1). At this time, as shown in Figure 4, when the elastic opening and closing member 130 is accommodated in the elastic member receiving hole 124, the plate spring 131 is extended, the space (d) to be inserted into the coupling bracket 116 is inserted A plate spring height limiting protrusion 124a is provided at an upper end of the inner wall surface forming the elastic member receiving hole 124 to prevent it from being secured.

The plate spring height limiting projections 124a are formed to protrude inward on both sides of the upper end of the elastic member receiving hole 124. Since the width W5 of the upper end of the elastic member receiving hole 124 is narrower than the width of the plate spring 131 by the plate spring height limiting projection 124a, the plate spring 131 is attached to the plate spring height limiting projection 124a. The height at which it stretches elastically is limited. Thereby, the space d into which the coupling bracket 116 is to be inserted is always empty at the upper end of the elastic member receiving hole 124.

In addition, since the plate spring 131 is not stretched to an initial state by being caught by the plate spring height limiting protrusion 124a, the plate spring 131 continues to act in an upward direction to be stretched to an initial state.

Meanwhile, a guide line 124b for guiding the movement of the plate spring 131 when the plate spring 131 is elastically compressed and stretched is formed on one inner wall surface of the elastic member receiving hole 124. The guideline 124b is formed to protrude a certain length toward the inside. That is, the elastic member receiving hole 124 has a width (W5) of the upper end where the coupling bracket 116 is inserted, a width (W6) of the middle region where the guide line (124b) is formed, and a width (W7) of the lower region. They are formed differently (W5<W6<W7).

The width (W5) of the upper end is formed narrower than the width of the plate spring (131), the width (W6) of the middle portion is formed with a slight margin than the width of the plate spring (131), the lower width (W7) It is formed larger than the width of the leaf spring (131).

4, the guide groove 133b of the leaf spring 131 is inserted into the guide line 124b. The guide line 124b protruding inward is inserted into the guide groove 133b, and in this state, the leaf spring 131 is compressed or extended and the height is adjusted. Since the guide groove 133b is inserted into the guide line 124b, the plate spring 131 is moved along the guide line 124b during the height adjustment process, so that the plate spring 131 is outside the elastic member receiving hole 124. It is possible to prevent the deviation.

Here, the guide line 124b is formed only on one side of the elastic member receiving hole 124 is to facilitate the assembly of the plate spring 131 in the elastic member receiving hole 124.

The lower portion of the elastic member receiving hole 124 is provided with a plate spring fitting protrusion 124c protruding vertically. The plate spring fitting protrusion 124c is inserted into the through hole 131a of the plate spring 131 so that the plate spring 131 is fixed to the elastic member receiving hole 124.

In this way, the guide line 124b is formed on both sides of the elastic member receiving hole 124 in the assembly process of inserting the plate spring 131 into the plate spring fitting protrusion 124c, so that the width W6 of the middle portion is the plate spring 131. When formed to correspond to the width of the plate spring 131 it is difficult to fit the plate spring fitting protrusion (124c). Accordingly, the guide line 124b is formed only on one side of the elastic member receiving hole 124 so that a minimum free space for assembling the plate spring 131 to the plate spring fitting protrusion 124c is formed in the width W6 of the intermediate region. do.

On the other hand, an elastic member fixing button 125 is protruded below the bracket coupling end 123. The elastic member fixing button 125 is formed to protrude at a certain height in a circular tube shape, and is fitted into the button receiving hole 137a of the elastic opening and closing member 130.

The elastic opening/closing member 130 is simultaneously fitted to the plate spring fitting protrusion 124c and the elastic member fixing button 125 so that the position of the rotating clamp 120 is fixed.

The elastic opening and closing member 130 is coupled to the rotational clamp 120 so that the rotational clamp 120 is detachably coupled to the fixed clamp 110. The elastic opening and closing member 130 is formed in a C-shaped bent plate spring 131, a horizontal coupling surface 133 formed vertically on the top of the plate spring 131, and perpendicular to the bottom of the plate spring 131 The formed lower support surface 137 is included.

The plate spring 131 is provided to be folded so that the upper plate and the lower plate are elastically adjusted in height. The plate spring 131 is held or compressed in a state accommodated in the elastic member receiving hole 124, and the height is adjusted elastically. The through-hole 131a is formed through the plate spring 131 along the longitudinal direction. As described above, the plate spring height limit protrusion 124a of the elastic member receiving hole 124 is inserted into the through hole 131a.

On one outer periphery of the upper plate of the plate spring 131, a guide groove 133b having a predetermined depth is recessed in an inner direction. The guide groove 133b is fitted into the guide groove 133b of the elastic member receiving hole 124 as shown in FIG. 4 to prevent the plate spring 131 from being displaced when the height of the plate spring 131 is adjusted. .

The horizontal coupling surface 133 is formed to extend a certain area horizontally on the top of the leaf spring 131. The horizontal coupling surface 133 is formed to protrude a predetermined length outward in the closed state as shown in FIG. 2. On the plate surface of the horizontal coupling surface 133, the inclined projections 133a are formed to protrude at an angle at an upward angle. An end portion of the horizontal coupling surface 133 is provided with a handle 135 to which a worker applies force.

The inclined protrusion 133a is inserted into the inclined protrusion fastening hole 116a of the coupling bracket 116 inserted into the elastic member receiving hole 124 when the rotating clamp 120 is coupled to the fixed clamp 110. The closed state of the 110 and the rotating clamp 120 is restricted.

As shown in Fig. 6 (a), when the pivoting clamp 120 is rotated in a direction coupled to the fixed clamp 110 as shown in Fig. 6 (b) in the open state, the elastic member receiving hole ( Coupling bracket 116 is inserted into the top of 124). As the coupling bracket 116 is inserted, the inclined protrusion 133a of the horizontal coupling surface 133 is pressed down.

As shown in Figure 6 (c), when the bracket coupling end 123 is in contact with the vertical support plate 115 and the insertion of the coupling bracket 116 is completed, the inclined protrusion 133a is inclined protrusion fastening hole 116a It is located at the bottom of the. Since the pressing force used to press down the inclined protrusion 133a is released, the inclined protrusion 133a elastically rises to the initial position and fits into the inclined protrusion fastening hole 116a.

As shown in Figure 5, while the inclined protrusion 133a is inclinedly fitted inside the inclined protrusion fastening hole 116a, the coupling bracket 116 is constrained inside the bracket coupling end 123. Accordingly, the closed state in which the rotation clamp 120 is coupled to the fixed clamp 110 may be stably maintained.

Here, the plate spring 131 is not stretched to the initial state by the plate spring height limiting protrusion 124a and is accommodated in the elastic member receiving hole 124 in a compressed state to some extent. As a result, the plate spring 131 always exerts an elastic force in an upward direction to be stretched to an initial state.

In the state in which the inclined protrusion 133a is fastened to the inclined protrusion fastening hole 116a, the plate spring 131 exerts an elastic force in the upward direction even though time passes, so the inclined protrusion 133a is inclined protrusion fastening hole 116a Since it does not come out from, the fixed state of the fixed clamp 110 and the rotating clamp 120 can be stably maintained.

On the other hand, when the operator needs to open the rotating clamp 120 coupled to the fixed clamp 110, the operator applies a force (P) to the handle 135 in the direction of lowering the handle 135. As a result, the handle 135 and the horizontal coupling surface 133 are pressed down, as shown by a dotted line in FIG. 5, and the plate spring 131 is compressed at the first height h1 to the second height h2. Lowered.

As the plate spring 131 and the horizontal coupling surface 133 descend, the inclined projection 133a, which was fitted in the inclined projection fastening hole 116a, also descends and is separated from the inclined projection fastening hole 116a. When the inclined protrusion 133a is separated and the operator rotates the rotating clamp 120 in a direction separated from the fixed clamp 110, the pipe hanger 100 is switched to the open state.

The lower support surface 137 is formed in a vertical direction in the lower portion of the plate spring 131. The lower support surface 137 is fixed to the bracket coupling end 123 as shown in FIGS. 3 and 4 so that the position of the elastic opening and closing member 130 is fixed.

A button receiving hole 137a is formed through the lower supporting surface 137. The elastic member fixing button 125 is forcibly fitted into the button receiving hole 137a to fix the elastic opening/closing member 130 to the rotating clamp 120.

A process in which the pipe hanger 100 of the present invention having such a configuration is installed on the ceiling to support the pipe A will be described with reference to FIGS. 1 to 6.

For the assembly of the pipe hanger 100, the elastic opening and closing member 130 is coupled to the rotating clamp 120. 3 and 4, the elastic opening and closing member 130 is coupled to the elastic member receiving hole 124 of the rotating clamp 120. As shown in FIGS. The plate spring 131 is inserted into the elastic member receiving hole 124 so that the guide groove 133b of the plate spring 131 fits into the guide line 124b, and the plate is inserted into the through hole 131a of the plate spring 131. Fit the spring fitting projection (124c). Then, the elastic member fixing button 125 is inserted into the button receiving hole 137a of the lower support surface 137 to complete the combination of the rotation clamp 120 and the elastic opening and closing member 130.

The rotation clamping end 117 of the fixed clamp 110 is inserted at an angle to the coupling end insertion hole 126 of the rotational clamp 120 to engage the rotational clamp engagement end 117.

When the assembly of the piping hanger 100 is completed, the worker moves under the ceiling where the piping hanger 100 is to be installed using a ladder or the like. At this time, the anchor bolt (B) is vertically installed in advance on the ceiling.

The anchor bolt (B) is screwed to the nut (114) formed on the anchor bolt fixing plate (113) of the fixing clamp (110) to fix the fixing clamp (110) to the anchor bolt (B).

In this state, the rotating clamp 120 is opened as much as possible to insert the pipe A into the fixed clamp body 111 and the rotating clamp body 121. And, as shown in Figure 6 (a), the rotating clamp 120 is rotated to the fixed clamp (110) side.

6(b), the coupling rib 123a of the bracket coupling end 123 is inserted into the rib insertion hole 115a of the vertical support plate 115, and the coupling bracket 116 is an elastic member receiving hole It is inserted into the top of 124.

When the coupling bracket 116 is pressed downward by the pressure at which the coupling member 116 is inserted into the elastic member receiving hole 124, and the insertion of the coupling bracket 116 is completed, illustrated in FIG. 6(c) As described above, the inclined protrusion 133a is elastically moved upward and is inserted into the inclined protrusion fastening hole 116a of the coupling bracket 116.

As the inclined protrusion 133a is inserted into the inclined protrusion fastening hole 116a, the combination of the rotating clamp 120 and the fixed clamp 110 is completed.

1 and 5, the inclined protrusion 133a is inserted into the inclined protrusion fastening hole 116a of the coupling bracket 116 to stop the movement of the coupling bracket 116, so that the rotation clamp 120 and the fixed clamp The coupling state of 110 may be stably maintained. Thereby, the piping (A) can be stably mounted inside the piping hanger (100) to maintain its position.

On the other hand, when it is necessary to separate the pipe (A) from the pipe hanger 100 for the replacement or repair of the pipe (A), as shown in Figure 5, the operator in the direction that the handle 135 is directed downward ( P) is applied.

As a result, the horizontal coupling surface 133 is lowered and the plate spring 131 is compressed, so that the inclined protrusion 133a is separated from the inclined protrusion fastening hole 116a. As the inclined protrusion 133a is separated, the binding force between the rotating clamp 120 and the fixed clamp 110 is released, and the rotating clamp 120 can be switched to the open state as shown in FIG.

As described above, in the hanger for piping according to the present invention, the rotating clamp can be fixed to the fixed clamp while the inclined protrusion elastically descends and rises with only one action in which the rotating clamp is pushed in the direction in which the operator clamps the fixed clamp. have.

In addition, even when the hanger for the piping in the closed state is switched to the open state, only the operation of the operator pressing the handle down is required.

Accordingly, the work flow for installing and disassembling the worker's piping hanger is significantly reduced, thereby reducing the physical burden of the worker and reducing the time required for installation and disassembly.

In addition, since the elastic force is applied in the direction in which the plate spring extends, the inclined protrusion is stably inserted into the inclined protrusion fastening hole unless a force is applied to the lower portion. Thereby, the support state of the pipe hanger can be stably maintained even after a time has elapsed after the installation work.

The embodiment of the piping hanger of the present invention described above is only an example, and those skilled in the art to which the present invention belongs are well aware that various modifications and other equivalent embodiments are possible. Will be able to. Therefore, it will be understood that the present invention is not limited to the forms mentioned in the detailed description above.
