Description

[0001] HANGER FOR PIPE [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a hanger for plumbing, and more particularly, to a hanger for plumbing in which installation and disassembly are simple and the support state of the pipe is stably maintained.

Industrial facilities and buildings are equipped with various piping such as gas piping, waterworks and sewer piping, piping for heating and cooling, and various electric and communication facility piping. Such tubing extends from one location to another along the ceiling of the building.

When a pipe having a long length and a load is moved along the ceiling, deflection may occur or be released by the wind. In order to prevent such deflection and deviation of the piping, a plurality of piping hanger is installed at a predetermined interval on the ceiling, and the piping is placed inside the hanger for maintaining the piping in its original state and position.

One example of such a conventional hanger for plumbing is disclosed in Japanese Patent No. 1125262, Laid-Open Patent No. 2014-0090061, No. 0421489, No. 1166441, No. 0343998, No. 2013-0003379 have.

The installation work of the piping hanger is performed by the worker moving toward the ceiling using a ladder or the like. Conventionally, a pair of clamps are closed or opened by a hinge structure and can be wrapped around the outside of the pipe, or can be separated from the pipe. Here, any one of the pair of clamps is fixed to the anchor bolt vertically provided at the lower part of the ceiling.

However, the disclosed hanger for a conventional pipe has a complicated fixing structure for fixing a pair of clamps to each other in a state in which a pipe is housed in the inside thereof, and there is a disadvantage in that the worker's physical burden is large, there was.

In addition, the conventional hanger for piping has a disadvantage in that when the user hits the upper or lower end of a pair of clamps by hand during the installation work, the binding force between the hanger and the hanger becomes weak. If it is opened like this, the installation work must be repeated again, and the worker's work fatigue is further increased.

In addition, in the conventional hanger for piping, the connection state between the pair of clamps is released naturally by the weight or the load of the pipe. When the hanger for the pipe is opened in this way, there is a danger that the position of the pipe may be displaced or fall down to cause a safety accident.

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

It is another object of the present invention to provide a hanger for a pipe which can stably maintain a coupled state even during an installation operation.

Another object of the present invention is to provide a hanger for a pipe which can stably maintain the supporting state of a pipe even after a set time is hardened.

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

The object of the present invention can be achieved by a hanger for plumbing. The pipe hanger according to the present invention includes a fixing clamp 110 having an upper end coupled to an anchor bolt B vertically provided on a ceiling and surrounding a semicircle of one side of a pipe having a circular cross section; A rotation clamp 120 rotatably coupled to the fixed clamp 110 and surrounding the other half of the pipe; And an elastic opening and closing member 130 coupled to an upper portion of the pivoting clamp 120 and elastically stretched and compressed and adapted to engage or disengage the upper end of the pivoting clamp 120 with respect to the fixed clamp 110 .

According to one embodiment, the fixing clamp 110 includes a fixed clamp main body 111 which surrounds the outer periphery of one side of the pipe in a semicircular shape; An anchor bolt fixing plate 113 horizontally formed on an upper end of the fixing clamp main body 111 and having a nut 114 to which the anchor bolt B is coupled; A rotary clamp coupling end 117 provided at a lower end of the fixed clamp main body 111 and supporting the rotary clamp 120 so that the rotary clamp 120 is rotated; And a coupling bracket 116 extending horizontally toward the pivotal clamp 120 at an end of the fixed clamp main body 111 and having an oblique projection coupling hole 116a formed through the plate surface, ) Includes a rotating clamp main body (121) which surrounds the other outer periphery of the pipe in a semicircular shape in a direction opposite to the fixed clamp main body (111); A bracket coupling end 123 vertically coupled to an upper end of the rotation clamp body 121 and having an elastic member receiving hole 124 for receiving the elastic opening and closing member 130; And a coupling end insertion hole 126 into which the rotation clamping coupling end 117 is inserted so that the rotation clamp main body 121 and the fixed clamp main body 111 surround the entire outer circumferential edge of the cross section of the pipe A When the pivoting clamp main body 121 is rotated in a closed state, the engaging bracket 116 can be inserted into the upper portion of the elastic member receiving hole 124.

According to one embodiment, the elastic opening and closing member 130 includes a leaf spring 131 formed to be bent upward and downward and compressed and elongated by an external force and received in the elastic member receiving hole 124; When the leaf spring 131 is extended upwardly in the closed state, it is inserted into the inclined projection coupling hole 116a of the coupling bracket 116, And a horizontal engagement surface 133 provided with a slant projection 133a for applying a restraining force to maintain the state.

According to an embodiment of the present invention, an upper end of the bracket coupling end 123 is provided with a coupling rib 123a protruding horizontally toward the fixing clamp 110. The anchor bolt fixing plate 123, which is in contact with the bracket coupling end 123, A rib insertion hole 115a through which the coupling rib 123a is inserted in the closed state may be formed at an end of the insertion hole 113. [

The tubular hanger according to the present invention can be fixed to the fixed clamp while the slanted projections are elastically lowered and raised by only one operation of pivoting the pivotal clamp in the direction in which the worker closes the fixed clamp.

Further, when the pivotal clamp is fixed to the fixed clamp, not only is it engaged by the slant projections, but also the engagement ribs and the engagement brackets of the bracket coupling end are cross-inserted in the directions opposite to each other, Or the coupling state can be stably maintained even if an impact is applied from the bottom.

Further, even when the closed hanger for piping is switched to the opened state, only the operation of pushing down the handle is required by the operator.

As a result, the number of working lines for installing and disassembling the piping hanger of the worker is significantly reduced, the physical burden of the worker can be reduced, and the time required for installation and disassembly can be reduced.

Further, since the elastic force is applied in the direction in which the leaf spring is extended, the state in which the oblique projection is stably inserted into the oblique projection fastening hole is maintained as long as no force is applied to the lower portion. As a result, the support state of the hanger for piping can be stably maintained even after a lapse of time since the installation work.

For a better understanding of the present invention, a preferred embodiment of the present invention will be described with reference to the accompanying drawings. The embodiments of the present invention may be modified into various forms, and the scope of the present invention should not be construed as being limited to the embodiments described in detail below. The present embodiments are provided to enable those skilled in the art to more fully understand the present invention. Therefore, the shapes and the like of the elements in the drawings can be exaggeratedly expressed to emphasize a clearer description. It should be noted that in the drawings, the same members are denoted by the same reference numerals. Detailed descriptions of well-known functions and constructions which may be unnecessarily obscured by the gist of the present invention are omitted.

1 is an exemplary view showing a state where a hanger 100 for a pipe according to the present invention is installed on a ceiling so as to support a pipe A. Fig.

As shown in the drawings, the hanger 100 for a pipe according to the present invention includes a fixed clamp 110 fixedly coupled to an anchor bolt B provided vertically to a ceiling, a fixed clamp 110 coupled to the fixed clamp 110, And a resilient opening and closing member 130 coupled to the pivoting clamp 120 for coupling or disengaging the pivoting clamp 120 and the pivoting clamp 110.

The piping hanger 100 of the present invention is configured such that the operation of rotating the swing clamp 120 in the direction in which the swing clamp 120 is closed by the elastic force of the elastic opening and closing member 130 causes the swing clamp 120 to move to the stationary clamp And the rotary clamp 120 can be separated from the stationary clamp 110 and can be switched to the open state only by pressing the elastic opening and closing member 130 in the downward direction.

Accordingly, the working line and the working time of the worker can be remarkably shortened, and an advantage that the state in which the pivotal clamp 120 and the fixed clamp 110 are coupled by the elastic force of the elastic closing member 130 can be stably maintained have.

6 (a), the upper end of the pivoting clamp 120 is separated from the upper end of the fixed clamp 110, and the closed state is a state in which the upper end of the pivoting clamp 120 is separated from the upper end the upper end of the pivoting clamp 120 is coupled to the upper end of the fixed clamp 110 as shown in FIG. The pipe A is inserted or separated between the fixed clamp 110 and the pivoting clamp 120 in the open state and the pipe A is supported in a fixed state.

Fig. 2 is a perspective view showing the construction of the closed hanger 100, and Fig. 3 is an exploded perspective view showing the structure of the hanger 100 for a pipe.

The pipe hanger 100 supports the pipe A by clamping the outer periphery of the pipe A between the fixed clamp 110 and the pivoting clamp 120. The pipe A is generally formed in a circular section. Accordingly, the fixed clamp 110 and the pivoting clamp 120 are each formed in a semicircular shape corresponding thereto.

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

The fixed clamp 110 is fixedly coupled to an anchor bolt B fixed to the ceiling as shown in Fig. 1 so that the position of the hanger 100 for the pipe is fixed to the ceiling.

3, the fixed clamp 110 has a fixed clamp main body 111 which surrounds one side outer periphery with respect to a sectional shape of the pipe A in a semi-circular shape, and a fixed clamp main body 111 which is formed to extend to the upper portion of the fixed clamp main body 111 A nut 114 fixed to the anchor bolt fixing plate 113 and coupled to the anchor bolt B, a vertical support plate 115 formed perpendicularly to the anchor bolt fixing plate 113, And an engaging bracket 116 protruding horizontally from the support plate 115 to be engaged with the elastic opening and closing member 130.

The fixed clamp main body 111 is formed in a semicircular shape with a plate-like material having a constant width. The inner diameter of the fixed clamp main body 111 corresponds to the outer diameter of the pipe A as shown in Fig. Whereby the pipe A is received and supported inside the circle formed by the fixed clamp 110 and the pivotal clamp 120. [

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

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

The hanger 100 for a pipe according to the present invention is installed at a predetermined interval along a path where the pipe A is moved on the ceiling to support the pipe A to prevent deflection and deviation of the pipe A. Accordingly, the fixed clamp main body 111 is designed in such a manner that it can sufficiently withstand the weight of the pipe A, its thickness and width. The dimensions of the fixed clamp main body 111 may be changed differently depending on the purpose and type of use of the piping A. [

The anchor bolt fixing plate 113 is horizontally formed on the upper portion of the fixed clamp body 111 and is engaged with the nut 114. The anchor bolt fixing plate 113 is extended to the fixing clamp main body 111 by a connecting plate 113a. A nut 114 is fixed to the center of the anchor bolt fixing plate 113 by welding. The nut 114 is screwed to the anchor bolt B fixed to the ceiling to fix the position of the hanger 100 for the pipe as shown in Fig.

The worker places the nut 114 of the anchor bolt fixing plate 113 so as to be coaxial with the anchor bolt B so as to install the hanger 100 for the pipe and rotates the anchor bolt fixing plate 113 to rotate the nut 114 ) To the anchor bolt (B).

The vertical support plate 115 extends vertically downward at the end of the anchor bolt fixing plate 113. The vertical support plate 115 contacts and supports the bracket coupling end 123 of the pivotal clamp 120 in the closed state to limit the maximum pivot angle of the pivotal 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. [ The rib insertion hole 115a is inserted with a coupling rib 123a formed in the bracket coupling end 123 of the pivotal clamp 120 when the pivotal clamp 120 is closed.

As the engaging rib 123a is inserted into the rib insertion hole 115a, the pivotal clamp 120 can be engaged with the fixed clamp 110 at the correct position without turning. The rib insertion hole 115a is formed so as to pass through an area corresponding to the width and height of the engaging rib 123a.

The engaging bracket 116 is formed to protrude horizontally toward the pivotal clamp 120 at the lower end of the vertical support plate 115. The engaging bracket 116 is inserted into the elastic member receiving hole 124 of the bracket connecting end 123 and engaged with the elastic closing member 130 when the pivotal clamp 120 is closed. The closed state of the fixed clamp 110 and the pivotal clamp 120 can be restricted by the process of engaging the engaging bracket 116 with the elastic opening and closing member 130. [

An inclined projection fixing hole 116a through which the inclined projection 133a of the elastic opening and closing member 130 is inserted is formed in the interior of the coupling bracket 116. [ The inclined projection 133a of the elastic closing member 130 is inserted into the inclined projection fixing hole 116a in a closed state as shown in FIG. The inclined projection 133a is inserted into the inclined projection fixing hole 116a so that the engagement bracket 116 is restrained in the elastic opening and closing member 130. As a result, the closed state of the hanger 100 for piping can be stably maintained.

 The leading end 116b of the engaging bracket 116 is formed in a trapezoidal shape in which both sides are cut inwardly to facilitate insertion into the elastic member receiving hole 124. [ That is, the width W2 of the distal end 116b is formed to be narrower than the width W1 of the coupling bracket 116, so that insertion into the elastic member receiving hole 124 can be facilitated.

The pivoting clamp coupling end 117 is engaged with the coupling end insertion hole 126 of the pivoting clamp 120 to support the pivoting clamp 120 so as to be pivoted relative to the fixed clamp 110.

Conventional hanger for piping has been operated so that a pair of clamps are rotated by a hinge. However, there is a problem that the hinge is released from the closed state while the hinge is deformed by the weight of the pipe.

The pipe hanger 100 according to the present invention can stably maintain a coupled state even if a load of the pipe is applied by the physical coupling between the pivoting clamp coupling end 117 and the coupling end insertion hole 126 without a hinge .

The pivoting clamp coupling end 117 is formed by bending from the lower end of the fixed clamp main body 111 and is coupled to the coupling bending arm 117a inserted into the coupling end insertion hole 126 and to the end of the coupling bending arm 117a And a pivot support vane 117b which overlaps with the coupling end insertion hole 126. [

5, the connecting bending arm 117a is horizontally extended from the lower end of the fixed clamp body 111 and then bent inward at a predetermined angle to be inserted into the coupling end insertion hole 126 of the pivoting clamp 120, do. The pivot support vane 117b overlaps with the pivot clamp main body 121 on the inner side of the coupling end insertion hole 126 and serves as a pivot so that the pivotal clamp 120 is rotated.

The width W4 of the pivot support vane 117b is wider than the width W3 of the connecting bending arm 117a. The width W8 of the coupling end insertion hole 126 is formed to be larger than the width W3 of the coupling bending arm 117a and narrower than the width W4 of the rotation support vane 117b.

When assembling the hanger 100 for piping, the operator inserts the pivot support vane 117b into the coupling end insertion hole 126 by tilting the pivotal clamp 120. When the pivot support vane 117b is inserted into the inside of the pivot clamp body 121, the width of the pivot support vane 117b is narrower than the width of the mating end insertion hole 126 and is not released to the outside.

At this time, a coupling slit 126a is formed on the upper portion of the coupling-end insertion hole 126 to have a predetermined length in the vertical direction so that insertion of the rotation support vane 117b into the coupling-end insertion hole 126 is facilitated.

6 (a), when the pivotal clamping coupling end 117 is inserted into the coupling end insertion hole 126, as shown in Figs. 6 (b) and 6 (c) (120) can be pivoted about the pivot support vane (117b). At this time, the maximum opening angle of the pivoting clamp 120 can be adjusted by the inclination angle of the connecting bending arm 117a.

The pivotal clamp 120 is pivoted to the fixed clamp 110 so that the hanger 100 for a pipe is switched to a closed state or an open state to support or separate the pipe A from the pipe.

The rotary clamp 120 includes a rotary clamp main body 121 having a semicircular shape in a direction opposite to the fixed clamp main body 111 and a bracket coupling (123).

The rotating clamp main body 121 is formed in a semicircular shape surrounding the outer periphery of the pipe A. The rotating clamp main body 121 is formed to have the same outer diameter as the fixed clamp main body 111. One or more second light holes 122 are formed on the 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 is formed at the lower end of the rotation clamp main body 121 so that the rotation clamp main body 121 can be rotated on the rotation coupling end 117.

The bracket coupling end 123 is vertically provided at the upper end of the rotation clamp body 121 and is detachably coupled to the coupling bracket 116 while receiving the elastic opening and closing member 130 therein. The bracket coupling end 123 is formed in an area that can be contactably supported by the vertical support plate 115 in a closed state. At the upper end of the bracket coupling end 123, a coupling rib 123a protruding toward the coupling bracket 116 is provided.

The engagement rib 123a is inserted into the rib insertion hole 115a of the vertical support plate 115 to guide the engagement direction when the rotation clamp 120 is closed to the stationary clamp 110. [ In addition, since the engaging rib 123a is inserted into the rib insertion hole 115a so that the upper and lower positions are constrained, the engaging state can be stably maintained even if an external shock is applied during installation work of the hanger 100 for a pipe .

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

4 is a perspective view showing a state in which the elastic opening and closing member 130 is coupled to the pivotal clamp 120, and Fig. 5 is a sectional view showing the sectional configuration of the pipe hanger 100 in a closed state. 3 to 5, the elastic member receiving hole 124 accommodates the elastic opening / closing member 130, and when the rotating clamp 120 is coupled to the fixed clamp 110, The engaging bracket 116 is inserted.

 The elastic member receiving hole 124 is formed in an area where the leaf spring 131 of the elastic opening and closing member 130 can be received at a predetermined height h1. 4, when the elastic opening and closing member 130 is received in the elastic member receiving hole 124, the leaf spring 131 is extended and the space d into which the engaging bracket 116 is inserted A plate spring height restricting protrusion 124a is provided at the upper end of the inner wall surface forming the elastic member receiving hole 124 to prevent it from being secured.

The leaf spring height restricting protrusions 124a are formed to protrude inwardly from the upper both sides of the elastic member receiving hole 124. [ The width W5 of the upper end of the elastic member receiving hole 124 becomes narrower than the width of the leaf spring 131 by the leaf spring height restricting projection 124a so that the leaf spring 131 abuts on the leaf spring height restricting projection 124a The height of hanging and stretching is limited. As a result, the space d in which the engaging bracket 116 is inserted into the upper end of the elastic member receiving hole 124 is always empty.

Since the leaf spring 131 is not stretched in the initial state because it is caught by the leaf spring height restricting projection 124a, the leaf spring 131 continues to exert the elastic force in the upward direction in order to be stretched to the initial state.

A guide line 124b guiding the movement of the leaf spring 131 is formed on the inner wall surface of the elastic member receiving hole 124 when the leaf spring 131 is elastically compressed and elongated. The guide line 124b is formed so as to protrude a predetermined length toward the inside. That is, the elastic member receiving hole 124 has a width W5 of the upper end where the engaging bracket 116 is inserted, a width W6 of the intermediate region where the guide line 124b is formed, and a width W7 of the lower region (W5 < W6 < W7).

The width W5 of the upper end is formed to be narrower than the width of the leaf spring 131 and the width W6 of the middle portion is formed to have a margin slightly smaller than the width of the leaf spring 131, Is larger than the width of the leaf spring (131).

In the guide line 124b, the guide groove 133b of the leaf spring 131 is inserted as shown in FIG. A guide line 124b protruding inwardly is inserted into the guide groove 133b. In this state, the plate spring 131 is compressed or elongated and its height is adjusted. Since the guide groove 133b is inserted into the guide line 124b, the leaf spring 131 is moved along the guide line 124b during the height adjustment process, so that the leaf spring 131 is moved to the outside of the elastic member receiving hole 124 Can be prevented from being separated.

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

A plate spring fitting protrusion 124c protruding perpendicularly is provided at a lower portion of the elastic member receiving hole 124. The plate spring fitting protrusion 124c is inserted into the through hole 131a of the plate spring 131 and the plate spring 131 is fixed to the elastic member accommodation hole 124. [

The guide line 124b is formed on both sides of the elastic member receiving hole 124 so that the width W6 of the intermediate portion is smaller than the width W6 of the leaf spring 131, It is difficult to insert the leaf spring 131 into the leaf spring fitting projection 124c. The guide line 124b is formed only on one side of the elastic member receiving hole 124 so that the width W6 of the intermediate region forms a minimum clearance space in which the leaf spring 131 can be assembled to the leaf spring fitting projection 124c do.

On the other hand, an elastic member fixing button 125 protrudes from the bottom of the bracket coupling end 123. The elastic member fixing button 125 protrudes at a predetermined height in the form of a circular tube and is fitted in the button receiving hole 137a of the elastic opening and closing member 130. [

The elastic opening and closing member 130 is fitted to the leaf spring fitting protrusion 124c and the elastic member fixing button 125 at the same time and fixed to the pivoting clamp 120.

The elastic opening and closing member 130 is coupled to the pivoting clamp 120 so that the pivoting clamp 120 is detachably coupled to the fixed clamp 110. The elastic opening and closing member 130 includes a leaf spring 131 bent in a C shape, a horizontal coupling surface 133 formed vertically to the upper end of the leaf spring 131, And a lower surface ground surface 137 formed thereon.

 The plate spring 131 is provided so as to be folded so that the upper plate and the lower plate are elastically adjusted in height. The plate spring 131 is held in the elastic member receiving hole 124, and the height thereof is maintained or compressed, and the height thereof is elastically adjusted. A through hole 131a is formed through the plate spring 131 along the longitudinal direction. As described above, the through-hole 131a is inserted with the leaf spring height restricting projection 124a of the elastic member receiving hole 124.

A predetermined depth guide groove 133b is recessed inwardly on the outer periphery of one side of the top plate of the leaf spring 131. 4, the guide groove 133b is fitted into the guide groove 133b of the elastic member receiving hole 124 to prevent the leaf spring 131 from being displaced when the height of the leaf spring 131 is adjusted .

The horizontal coupling surface 133 extends horizontally on the upper end of the leaf spring 131 by a predetermined area. The horizontal coupling surface 133 is protruded by a predetermined length from the closed state to the outside as shown in FIG. On the surface of the horizontal engagement surface 133, a slant projection 133a is formed so as to protrude upward at a predetermined angle. At the end of the horizontal engagement surface 133, a handle 135 is provided for the operator to apply force.

The inclined projection 133a is inserted into the inclined projection fixing hole 116a of the engaging bracket 116 inserted into the elastic member receiving hole 124 when the rotating clamp 120 is engaged with the fixed clamp 110, So that the closed state of the rotary clamp 110 and the rotary clamp 120 are constrained.

As shown in FIG. 6 (a), when the pivotal clamp 120 is rotated in a direction to be engaged with the fixed clamp 110 as shown in FIG. 6 (b) in the open state, 124 are inserted into the upper ends of the engaging brackets 116. So that the inclined projection 133a of the horizontal engagement surface 133 is pressed down while the engagement bracket 116 is inserted.

6 (c), when the bracket coupling end 123 comes into contact with the vertical support plate 115 and the insertion of the coupling bracket 116 is completed, the inclined projection 133a is inserted into the inclined projection coupling hole 116a, As shown in FIG. The pressing force that presses the slant projection 133a downward is relieved, so that the slant projection 133a rises elastically to the initial position and is fitted in the slant projection fastening hole 116a.

The inclined projection 133a is inclined in the inclined projection fixing hole 116a so as to restrict the engagement bracket 116 to the inside of the bracket engagement end 123 as shown in FIG. As a result, the closed state in which the pivotal clamp 120 is coupled to the fixed clamp 110 can be stably maintained.

Here, the leaf spring 131 is not extended to the initial state by the leaf spring height restricting projection 124a, but is accommodated in the elastic member receiving hole 124 in a compressed state to some extent. As a result, the leaf spring 131 always exerts an elastic force in an upward direction to be stretched to an initial state.

The slant projections 133a are engaged with the slant projection fastening holes 116a so that the plate spring 131 exerts an upward force even when the time elapses in the state where the slant projections 133a are fastened to the slant fastening holes 116a. The engagement state of the stationary clamp 110 and the rotation clamp 120 can be stably maintained.

On the other hand, when the worker has to open the pivotal clamp 120 coupled to the fixed clamp 110, the worker applies a force P to the pull 135 in the direction of lowering the pull 135 downward. 5, the knob 135 and the horizontal coupling surface 133 are pressed downward, and the leaf spring 131 is compressed at the first height h1 to the second height h2 Lower.

The leaf spring 131 and the horizontal engaging surface 133 are lowered so that the inclined projection 133a that is sandwiched by the inclined projection coupling hole 116a is also lowered and separated from the inclined projection coupling hole 116a. When the operator turns the pivoting clamp 120 in a direction separating from the fixed clamp 110 in a state where the slant projection 133a is separated, the pipe hanger 100 is switched to the open state.

A bottom support surface 137 is formed at a lower portion of the leaf spring 131 in a vertical direction. 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 surface guide surface 137. The elastic member fixing button 125 is forcedly inserted into the button receiving hole 137a to fix the elastic opening and closing member 130 to the pivoting clamp 120. [

A process in which the hanger 100 for piping according to the present invention having such a configuration is installed on a ceiling to support the piping A will be described with reference to Figs. 1 to 6. Fig.

The elastic closure member 130 is engaged with the pivotal clamp 120 for assembling the hanger 100 for plumbing. As shown in FIGS. 3 and 4, the elastic opening and closing member 130 is engaged with the elastic member receiving hole 124 of the pivoting clamp 120. The leaf spring 131 is inserted into the elastic member receiving hole 124 so that the guide groove 133b of the leaf spring 131 is fitted in the guide line 124b and the leaf spring 131 is inserted into the through hole 131a of the leaf spring 131, Fit the spring fitting projection 124c. The elastic member fixing button 125 is inserted into the button receiving hole 137a of the lower support surface 137 to complete the coupling of the rotary clamp 120 and the elastic opening and closing member 130.

The turning support pin 117b of the fixing clamp 110 is inserted obliquely into the coupling end insertion hole 126 of the rotation clamp 120 and the rotation clamping coupling end 117 is engaged.

When the assembling of the hanger 100 for piping is completed, the worker moves down the ceiling on which the hanger 100 for a pipe is to be installed by using a ladder or the like. At this time, the anchor bolt B is vertically installed on the ceiling in advance.

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 rotary clamp 120 is opened to the maximum, and the pipe A is inserted into the fixed clamp body 111 and the rotary clamp body 121. Then, as shown in Fig. 6 (a), the rotation clamp 120 is rotated toward the fixed clamp 110 side.

The engaging rib 123a of the bracket connecting end 123 is inserted into the rib insertion hole 115a of the vertical supporting plate 115 and the engaging bracket 116 is inserted into the elastic member receiving hole 115a as shown in Figure 6 (b) (Not shown).

When the inclined projection 133a is pressed downward by the pressure that the engaging bracket 116 is inserted into the elastic member receiving hole 124 and the insertion of the engaging bracket 116 is completed, The oblique projection 133a is elastically moved upward and inserted into the oblique projection fastening hole 116a of the engaging bracket 116 as shown in Fig.

The inclined projection 133a is inserted into the inclined projection fixing hole 116a so that the coupling of the rotary clamp 120 and the fixed clamp 110 is completed.

The inclined projections 133a are inserted into the inclined projection fixing holes 116a of the engaging bracket 116 to prevent movement of the engaging bracket 116 as shown in Figs. 1 and 5, The coupling state of the coupling member 110 can be stably maintained. Thus, the piping A can be stably held in the hinges 100 for the piping so that the position can be maintained.

On the other hand, when the piping A is to be separated from the hanger 100 for replacement or repair of the piping A, as shown in Fig. 5, the worker moves the handle 135 in the downward direction P).

The horizontal coupling surface 133 is lowered and the leaf spring 131 is compressed so that the inclined projection 133a is separated from the inclined projection coupling hole 116a. The detent force between the rotary clamp 120 and the fixed clamp 110 is released as the slant projection 133a is separated and the rotary clamp 120 can be switched to the open state as shown in FIG.

As described above, the tubular hanger according to the present invention is capable of fixing the pivotal clamp to the fixed clamp by elastically descending and raising the pivotal projection by only one operation of pivoting the pivotal clamp in the direction in which the worker closes the fixed clamp have.

Further, even when the closed hanger for piping is switched to the opened state, only the operation of pushing down the handle is required by the operator.

As a result, the number of working lines for installing and disassembling the piping hanger of the worker is significantly reduced, the physical burden of the worker can be reduced, and the time required for installation and disassembly can be reduced.

Further, since the elastic force is applied in the direction in which the leaf spring is extended, the state in which the oblique projection is stably inserted into the oblique projection fastening hole is maintained as long as no force is applied to the lower portion. As a result, the support state of the hanger for piping can be stably maintained even after a lapse of time since the installation work.
