Description

[Technical Field]

[0001] The present invention relates to a clamp. [Background technology]

[0002] Generally, when connecting a branch pipe to a polyethylene pipe (hereinafter referred to as the pipe or main pipe) that carries tap water or gas, this is done using, for example, a saddle fitting or a saddle-equipped branch valve, which has a saddle body that is fused to the main pipe and a branch pipe section that serves as the connection point for the branch pipe. For example, saddle joints are usually configured as EF (electrofusion) joints, which are configured to melt the interface between the saddle joint and the main pipe by passing electricity through an electric heating wire placed inside the saddle body, causing it to heat up and join the two.

[0003] Conventionally, to join a saddle joint to a main pipe, the saddle joint is first brought into contact with the main pipe and fixed in place with a dedicated saddle joint fixing clamp. In this state, an electric heating wire is passed through to join the saddle joint and the main pipe. The molten joint is then solidified, and the clamp is then removed from the saddle joint and the main pipe, completing the process. Patent Document 1, for example, proposes such a clamp.

[0004] The clamp of Patent Document 1 has a locking plate formed on the flange of a saddle joint that abuts against a main pipe, located along the outer peripheral surface of the main pipe on the side facing the saddle, and whose underside abuts against the upper surface of the flange.The saddle joint and the clamp are fixed together by inserting and fitting a fixing member into an insertion hole formed by a first notch groove formed in the upper surface of the flange of the saddle joint and a second notch groove formed in the lower surface of the locking plate of the clamp at a position opposite the first notch groove.

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2011-208671 Summary of the Invention [Problem to be solved by the invention]

[0006] When the clamp of Patent Document 1 is placed on the saddle joint, a fixing member is inserted and fitted into an insertion hole formed by the notched grooves of the saddle joint and the clamp, and the fixing member is moved along the axial direction of the main pipe. At this time, the positions of the saddle joint and the clamp may become misaligned when the fixing member is inserted, making it impossible to securely fix the saddle joint and the main pipe. Furthermore, once the fixing member has fixed the saddle joint and the clamp, it is difficult to remove the fixing member, making it difficult to correct the position.

[0007] The present invention has been made in view of the above circumstances, and has as its object to provide a clamp that can prevent misalignment relative to the saddle joint and the main pipe. [Means for solving the problem]

[0008] In order to solve the above problems, the present invention proposes the following means. The clamp of the present invention is a clamp that holds a saddle joint placed on the outer surface of a pipe, and comprises a first member having a first positioning portion that is placed on a first saddle flange of the saddle joint and a first engaging portion, and a second member having a second positioning portion that is placed on a second saddle flange of the saddle joint and a second engaging portion that engages with the first engaging portion, and when the first engaging portion and the second engaging portion are engaged to assemble the first member and the second member, the first positioning portion and the second positioning portion are connected via a connecting strap.

[0009] According to this invention, the first engaging portion of the first member and the second engaging portion of the second member engage with each other. In other words, the first member and the second member can be engaged without the need for a separate fixing member such as a bolt or clip. This makes the fixing work easier and reduces the work time.

[0010] The first engaging portion may have a male sawtooth shape, and the second engaging portion may have a female sawtooth shape.

[0011] According to this invention, the first engagement portion has a male saw blade shape, and the second engagement portion has a female saw blade shape. That is, the first member and the second member are engaged by the saw blade shape. Therefore, the engagement work can be performed manually without using special tools. This makes the fixing work easier.

[0012] In addition, the first member may include a first belt-shaped member having one end connected to the first arrangement portion and the other end formed with the first engagement portion, forming the connecting belt, and the second engagement portion may be located in the second arrangement portion.

[0013] According to this invention, the first member includes a first band-shaped member having one end connected to the first arrangement portion and the other end having the first engagement portion formed thereon, and forming a connecting band, and the second engagement portion is located in the second arrangement portion. In other words, the connecting band is formed only on the first member. This structure makes it easier to apply force by hand when engaging the first engagement portion and the second engagement portion.

[0014] In addition, the first member may include a first belt-shaped member having one end connected to the first arrangement portion and the other end formed with the first engagement portion, and forming part of the connecting band, and the second member may include a second belt-shaped member having one end connected to the second arrangement portion and the other end formed with the second engagement portion, and forming part of the connecting band.

[0015] According to this invention, the first member includes a first band-shaped member, and the second member includes a second band-shaped member. A first engagement portion is formed at the other end of the first band-shaped member, and a second engagement portion is formed at the other end of the second band-shaped member. In other words, the first engagement portion and the second engagement portion engage on the outer peripheral surface of the pipe to which the saddle joint is attached. This facilitates the engagement of the engagement portions when the layout of the construction site makes it difficult to work near the flange of the saddle joint.

[0016] The first strip-shaped member may also include a first reinforcing member.

[0017] The second strip-shaped member may also include a second reinforcing member.

[0018] According to this invention, the first belt-shaped member is provided with a first reinforcing member, and the second belt-shaped member is provided with a second reinforcing member, which prevents the first belt-shaped member or the second belt-shaped member from shifting position when engaging the engaging portions, making the work easier.

[0019] Further, a handle may be provided on the first member, the second member, or both.

[0020] According to this invention, the first member, the second member, or both of them are provided with a handle, which can be grasped when engaging, making the operation easier.

[0021] The first member and the second member may be made of resin.

[0022] According to this invention, the first and second members are made of resin. This allows each member to be lightweight, making it easy to transport to the work site. Furthermore, each member can be manufactured inexpensively, allowing a large number of clamps to be prepared at the construction site. Therefore, the work of holding the saddle fitting and the pipe can be performed at multiple locations simultaneously, shortening the work time. [Effects of the Invention]

[0023] According to the present invention, it is possible to provide a clamp that can be prevented from shifting position relative to the saddle joint and the main pipe. [Brief explanation of the drawings]

[0025] Hereinafter, a clamp according to an embodiment of the present invention will be described with reference to the drawings. As shown in Figures 1 and 2, the saddle fitting 11 is a fitting that connects a branch pipe 30 (a branch pipe) to a main pipe 20 (a pipe) through which, for example, tap water or gas flows. The saddle fitting 11 is usually configured as an EF fitting (electrofusion fitting, electrofusion joint). The saddle fitting 11 is configured so that the saddle body 12 is brought into close contact with the main pipe 20, and an electric heating wire (not shown) provided inside the saddle body 12 is heated, thereby fusing the saddle fitting 11 and the main pipe 20. By fusing the saddle fitting 11 and the main pipe 20, the branch pipe 30 is connected to the branch pipe portion 16 of the saddle fitting 11, and the branch pipe 30 is connected to the main pipe 20.

[0026] The saddle joint unit 10 includes a saddle joint 11 fused to a first side of the main pipe 20, and a clamp (saddle clamp, saddle jig) disposed on a second side of the main pipe 20. The main pipe 20 is clamped between the saddle joint 11 and the clamp. In this state, the main pipe 20 is tightly attached to the saddle joint 11. Hereinafter, the axial direction of the main pipe 20 may be referred to as the "axial direction," the radial direction of the main pipe 20 as the "radial direction," and the circumferential direction of the main pipe 20 as the "circumferential direction." In addition, one side in a direction perpendicular to the axis of the main pipe 20 will be referred to as the "first side," and the other side will be referred to as the "second side" opposite the first side.

[0027] As shown in FIG. 1, the saddle joint 11 has a saddle body 12, a first saddle flange 14, a second saddle flange, and a branch pipe portion 16. The saddle body 12 is curved along the main pipe 20 and is fused to a first outer peripheral surface 20a, which is the outer peripheral surface of the first side of the main pipe 20. A circular hole is formed in the center of the saddle body 12 to allow communication between the main pipe 20 and the branch pipe 30. A branch pipe section 16 is formed in the saddle body 12 along the outer peripheral edge of the circular hole. The branch pipe section 16 protrudes from the outer peripheral edge of the circular hole toward the radial outside (first side) of the main pipe 20. The saddle body 12 is provided with terminals 13 on both sides of the branch pipe portion 16 in the axial direction. The terminals 13 are connected to heating wires embedded in the saddle body 12.

[0028] The saddle body 12 is formed in an arc shape with substantially the same curvature as the main pipe 20 so that it can be fused to the main pipe 20. The saddle body 12 is formed so that substantially the entire inner surface can come into close contact with the first outer peripheral surface 20a of the main pipe 20. A first saddle flange 14 and a second saddle flange 15 are formed on each side edge of the saddle body 12 along the axial direction of the main pipe 20. The first saddle flange 14 and the second saddle flange 15 protrude radially outward from both side ends of the arc shape of the saddle body 12.

[0029] 1 to 3, the saddle joint 11 is disposed on a first outer circumferential surface 20a of a cylindrical main pipe 20. In this state, the saddle joint 11 is fixed to the main pipe 20 by a clamp. The clamps according to this embodiment will be described below in terms of a first clamp 100 according to a first embodiment and a second clamp 200 according to a second embodiment. In this embodiment, the term "clamp" refers to both the first clamp 100 and the second clamp 200.

[0030] (First clamp 100) The first clamp 100 shown in Fig. 1 holds a saddle joint 11 arranged on a first outer peripheral surface 20a of a main pipe 20. As shown in Fig. 1, the first clamp 100 includes a first member 110 and a second member 120. In this embodiment, the first member 110 and the second member 120 are formed from resin. Suitable molding methods include, for example, integral molding by injection molding or cutting out by cutting. The first member 110 includes a first arrangement portion 111, a first engagement portion 112, a first strip-shaped member 113 (connecting strip), a first reinforcing member 114, and a handle 115.

[0031] The first arrangement portion 111 is arranged on the first saddle flange 14 of the saddle joint 11. The first arrangement portion 111 is a rod-shaped member whose longitudinal direction is in the axial direction. One end of the first band-shaped member 113 is connected to both longitudinal ends of the first arrangement portion 111. Therefore, the length of the first arrangement portion 111 is formed to be at least longer than the axial length of the first saddle flange 14 so that the first saddle flange 14 and the first band-shaped member 113 do not interfere with each other.

[0032] The first engagement portion 112 engages with a second engagement portion 122 provided on the second member 120. The first engagement portion 112 is formed on the other end of the first strip-shaped member 113. The first engagement portion 112 has a male sawtooth shape. As shown in FIG. 3 , the male sawtooth shape is an uneven shape in which an inclined surface 112a that is inclined with respect to the traveling direction D and an orthogonal surface 112b that is perpendicular to the traveling direction D are continuously provided. The traveling direction D is the direction in which the first engagement portion 112 advances relative to the second engagement portion 122 when the first engagement portion 112 engages with the second engagement portion 122. In the first engagement portion 112 of the first clamp 100, the male sawtooth shape is provided on both the first side and the second side.

[0033] The first band-shaped member 113 is arranged along the circumferential direction of the second outer peripheral surface 20b, which is the outer peripheral surface on the second side of the main pipe 20, and supports the saddle joint 11 and the main pipe 20. The first band-shaped member 113 has a curved shape that matches the curvature of the main pipe 20. A pair of first band-shaped members 113 are provided at both axial ends of the saddle joint 11. One end of the first band-shaped member 113 is connected to the axial end of the first arrangement portion 111, and the first engagement portion 112 is formed at the other end.

[0034] 5, first protrusions 113a and second protrusions 113b may be provided on the surface of the first band-shaped member 113 that contacts the main pipe 20. The first protrusions 113a are provided in the longitudinal direction of the first band-shaped member 113, i.e., along the circumferential direction of the main pipe 20. The second protrusions 113b are provided in a direction perpendicular to the first protrusions 113a, i.e., along the axial direction of the main pipe 20. By providing the protrusions in this manner, when the first band-shaped member 113 is arranged along the circumferential direction of the main pipe 20, only the first protrusions 113a and the second protrusions 113b contact the main pipe 20. This reduces the contact area, which may improve the clamping force of the first band-shaped member 113 on the main pipe 20.

[0035] As shown in FIG. 4, the first reinforcing member 114 connects the pair of first band-shaped members 113 in the axial direction. This makes it difficult for the pair of first band-shaped members 113 to shift position. The connecting location is preferably the midpoint of the first band-shaped members 113 in the circumferential direction. Alternatively, this may be changed as appropriate depending on the design conditions. For example, the first reinforcing member 114 may be provided at a position closer to one end or the other end of the first band-shaped member 113 in the circumferential direction. The first reinforcing member 114 may be provided at not only one location but also multiple locations in the circumferential direction.

[0036] The handles 115 are provided for the user to grasp when engaging the first engagement portion 112 and the second engagement portion 122. This makes it easier for the user to apply force during engagement. As shown in FIG. 4, the handles 115 are provided in four locations, for example, one on each end of the pair of first band-shaped members 113 in the circumferential direction. Alternatively, the attachment locations and number may be determined arbitrarily as needed. In addition, although the handles 115 are rod-shaped extending in the axial direction in this embodiment, the shape is not limited to this. For example, they may be annular so that fingers can be easily hooked during engagement.

[0037] As shown in Figures 6 and 7, the second member 120 is a plate-shaped member. The second member 120 includes a second arrangement portion 121 and a second engagement portion 122. The second member 120 engages with the first member 110 to ensure that the saddle fitting 11 and the main pipe 20 are fixed together. Specifically, the first engagement portion 112 of the first member 110 engages with the second engagement portion 122 of the second member 120.

[0038] The second arrangement portion 121 is arranged on the second saddle flange 15 of the saddle joint 11. The second arrangement portion 121 is a plate-shaped member, and has a second engagement portion 122 inside the plate. The axial length of the second arrangement portion 121 is equal to the distance between the pair of first band-shaped members 113.

[0039] The second engagement portion 122 engages with the first engagement portion 112. As shown in FIG. 3, the second engagement portion 122 is located inside the second arrangement portion 121. The second engagement portion 122 has a female saw blade shape corresponding to the male saw blade shape of the first engagement portion 112. That is, as shown in FIG. 6, the second engagement portion 122 has a concave-convex shape in which an inclined surface 122a that is inclined with respect to the direction of advancement D of the male saw blade shape of the first engagement portion 112 and an orthogonal surface 122b that is perpendicular to the direction of advancement D are continuously provided. In the second engagement portion 122 of the first clamp 100, the female saw blade shape is provided on both the first side and the second side.

[0040] A plurality of second engagement portions 122 are provided in a direction from the first side to the second side (hereinafter also referred to as the first direction). Any one of the plurality of second engagement portions 122 is appropriately selected and engaged with the first engagement portion 112, thereby adjusting the clamping margin of the main pipe 20 by the first belt-shaped member 113. 7, the second engagement portions 122 are provided over the entire length of the second arrangement portion 121. Alternatively, as shown in Fig. 8, the second engagement portions 122 may be provided only at both ends of the second arrangement portion 121 in the length direction.

[0041] The main pipe 20 and the saddle joint 11 are fixed together using the first clamp 100 having the above-described configuration as follows: First, the first arrangement portion 111 of the first member 110 is arranged so that its longitudinal direction is aligned with the longitudinal direction of the first saddle flange 14. As a result, one ends of the pair of first belt-shaped members 113 are arranged at both axial ends of the first saddle flange 14. Next, the second member 120 is placed so that its longitudinal direction is aligned with the longitudinal direction of the second saddle flange 15. At this time, the second engaging portion 122 is placed so that it faces the first saddle flange 14 side so that it can engage with the first engaging portion 112.

[0042] In the above-described state, the first engagement portion 112 is pushed into the second engagement portion 122 to engage with it. That is, the first engagement portion 112 is advanced in the moving direction D relative to the second engagement portion 122 to engage the first engagement portion 112 with the second engagement portion 122. The moving direction D is also a direction perpendicular to both the axis of the main pipe 20 and the first direction. At this time, the handle 115 may be gripped to make it easier to apply the pushing force. When the first engagement portion 112 is pushed into the second engagement portion 122, the inclined surfaces 112a and 122a of the first engagement portion 112 come into contact with each other. This causes the pushing force to act to push the second engagement portion 122 apart. This allows the first engagement portion 112 to enter the interior of the second engagement portion 122. When an attempt is made to remove the first engagement portion 112 pushed into the second engagement portion 122, the perpendicular surfaces 112b and 122b of the first engagement portion 112 come into contact with each other. At this time, the pulling force does not act in a direction that pushes apart the second engagement portions 122. This prevents the first engagement portions 112 from coming out of the second engagement portions 122.

[0043] By engaging the first engaging portion 112 and the second engaging portion 122 in this manner, the first member 110 and the second member 120 are assembled together. In other words, the first arrangement portion 111 and the second arrangement portion 121 are connected via the first band-shaped member 113. As a result, the main pipe 20 is tightened by the first clamp 100, and the saddle fitting 11 and the main pipe 20 are fixed together. At this time, the first band-shaped member 113 functions as a connecting band that connects the first arrangement portion 111 and the second arrangement portion 121 together.

[0044] (Second clamp 200) Next, a description will be given of the second clamp 200. Note that, for the second clamp 200, the same parts as those of the first clamp 100 are given the same reference numerals, and the description thereof will be omitted, and only the differences will be described.

[0045] The second clamp 200 shown in Figures 9, 10, and 11 holds the saddle joint 11 arranged on the first outer peripheral surface 20a of the main pipe 20. As shown in Figure 9, the second clamp 200 includes a first member 210 and a second member 220. In this embodiment, the first member 210 and the second member 220 are formed from resin. Suitable molding methods include, for example, integral molding by injection molding or cutting out by cutting. The first member 210 includes a first arrangement portion 111, a first engagement portion 212, a first strip-shaped member 113 (connecting strip), and a first reinforcing member 114.

[0046] The first arrangement part 111 is identical to the first clamp 100 . The first engagement portion 212 engages with a second engagement portion 222 provided on the second member 220. The first engagement portion 212 is formed on the other end of the first band-shaped member 113. The first engagement portion 212 has a male sawtooth shape. The second clamp 200 differs from the first clamp 100 in that the male sawtooth shape is provided only on the second side, but is otherwise identical to the first clamp 100. The first engagement portion 212 of the second clamp 200 also differs from the first clamp 100 in that it has a gripping portion 212t. The gripping portion 212t is a portion that an operator grips when engaging the first engagement portion 212 with the second engagement portion 222.

[0047] The first belt-shaped member 113 in the second clamp 200 is basically the same as that in the first clamp 100, but differs in the following respects. Specifically, the shape of the first engagement portion 212 provided at the other end differs from that in the first clamp 100. The second clamp 200 also differs from the first clamp 100 in that the length in the circumferential direction of the main pipe 20 is shorter. The second clamp 200 also differs from the first clamp 100 in that the surface facing the main pipe 20 does not have a second protrusion 113b. The first reinforcing member 114 is identical to the first clamp 100 . 9, 10 and 11, the handle 115 is not shown, but may also be provided on the first member 210 of the second clamp 200.

[0048] The second member 220 includes a second arrangement portion 221, a second engagement portion 222, a second strip-shaped member 213 (connecting strip), and a second reinforcing member 214.

[0049] The second arrangement portion 221 is identical to the first arrangement portion 111 of the first clamp 100 . The second engagement portion 222 engages with the first engagement portion 212. As shown in FIG. 10 , the second engagement portion 222 of the second clamp 200 is provided at the other end of the second belt-shaped member 213. The second engagement portion 222 has a female saw blade shape that corresponds to the male saw blade shape of the first engagement portion 212. The second clamp 200 differs from the first clamp 100 in that the male saw blade shape is provided only on the second side, but is otherwise identical. Furthermore, the second engagement portion 222 of the second clamp 200 has a gripping portion 222t, similar to the first engagement portion 212.

[0050] The second belt-shaped member 213 has a structure basically equivalent to that of the first belt-shaped member 113 of the second clamp 200. The second belt-shaped member 213 has a second arrangement portion 221 at one end and a second engagement portion 222 at the other end. The second belt-shaped member also has a protrusion 213a in the circumferential direction. The protrusion 213a is identical to the first protrusion 113a of the first clamp 100. The second reinforcing member 214 is identical to the first reinforcing member 114 . Although not shown, a handle 115 may also be provided on the second member 220 of the second clamp 200.

[0051] The main pipe 20 and saddle joint 11 are fixed together using the second clamp 200 having the above-described configuration as follows: First, the first arrangement portion 111 of the first member 210 is arranged so that its longitudinal direction is aligned with the longitudinal direction of the first saddle flange 14. As a result, one ends of the pair of first belt-shaped members 113 are arranged at both axial ends of the first saddle flange 14. Next, the second arrangement portion 221 of the second member 220 is arranged so that its longitudinal direction is along the longitudinal direction of the second saddle flange 15. As a result, one end of the pair of second belt-shaped members 213 is arranged at both axial ends of the second saddle flange 15.

[0052] In the above-described state, first engagement portion 212 is engaged by pushing it into second engagement portion 222. At this time, gripping portions 212t and 222t may be gripped to make it easier to apply the pushing force. The structure of engagement between the male saw blade shape and the female saw blade shape is the same as that of first clamp 100. By engaging the first engaging portion 212 and the second engaging portion 222 in this manner, the first member 210 and the second member 220 are assembled together. That is, the first arrangement portion 111 and the second arrangement portion 221 are connected via the first band-shaped member 113 and the second band-shaped member 213. As a result, the main pipe 20 is tightened by the first clamp 100, and the saddle fitting 11 and the main pipe 20 are fixed. At this time, the first band-shaped member 113 and the second band-shaped member 213 function as parts of a connecting band that connects the first arrangement portion 111 and the second arrangement portion 221.

[0053] As described above, with the clamp according to this embodiment, the first engagement portions 112, 212 of the first members 110, 210 engage with the second engagement portions 122, 222 of the second members 120, 220. In other words, the first members 110, 210 and the second members 120, 220 can be engaged with each other without the need for separate fixing members such as bolts or clips. This makes the fixing work easier and reduces the time required for the work.

[0054] Furthermore, the first engagement portions 112, 212 have a male saw blade shape, and the second engagement portions 122, 222 have a female saw blade shape. In other words, the first members 110, 210 and the second members 120, 220 are engaged with each other by the saw blade shape. Therefore, the engagement work can be performed manually without using special tools. This makes the fixing work easier.

[0055] Furthermore, the first member 110 of the first clamp 100 includes a first belt-shaped member 113 having one end connected to the first arrangement portion 111 and the other end having a first engagement portion 112 formed thereon, and forming a connecting band, and the second engagement portion 122 of the first clamp 100 is located in the second arrangement portion 121. In other words, the connecting band is formed only on the first member 110. With this structure, it is easier to apply force by hand when engaging the first engagement portion 112 and the second engagement portion 122.

[0056] Furthermore, the first member 210 of the second clamp 200 includes a first belt-shaped member 113, and the second member 220 of the second clamp includes a second belt-shaped member 213. Furthermore, a first engagement portion 212 is formed at the other end of the first belt-shaped member 113 of the second clamp 200, and a second engagement portion 222 is formed at the other end of the second belt-shaped member 213 of the second clamp 200. In other words, the first engagement portion 212 and the second engagement portion 222 engage on the outer peripheral surface of the pipe to which the saddle fitting 11 is attached. This makes it easier to engage the engagement portions when the layout of the construction site makes it difficult to work near the flange of the saddle fitting 11.

[0057] In addition, the first belt-shaped member 113 is provided with a first reinforcing member 114, and the second belt-shaped member 213 is provided with a second reinforcing member 214. This prevents the first belt-shaped member 113 or the second belt-shaped member 213 from shifting position when engaging the engaging portions, making the work easier.

[0058] Furthermore, a handle 115 is provided on the first member 110, 210 and / or the second member 220. This allows the handle 115 to be grasped when engaging, making the operation easier.

[0059] Furthermore, the first members 110, 210 and the second members 120, 220 are made of resin. This allows each member to be lightweight, making it easy to transport to the work site. Furthermore, each member can be manufactured inexpensively, allowing a large number of clamps to be prepared at the construction site. Therefore, the saddle fitting 11 and the main pipe 20 can be held at multiple locations simultaneously, shortening the work time.

[0060] The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, the male saw blade shape and female saw blade shape may be as follows: That is, the male saw blade shape and female saw blade shape may be provided only on the first side or the second side of the first clamp 100; The male saw blade shape and female saw blade shape may be provided on both the first side and the second side of the second clamp 200; Or, the male saw blade shape and female saw blade shape may be provided only on the first side of the second clamp 200. Additionally, a handle 115 may be provided on the second member 120 of the first clamp 100 .

[0061] In addition, within the scope of the spirit of the present invention, the components in the above-described embodiments may be replaced with well-known components as appropriate, and the above-described modifications may be combined as appropriate. [Explanation of symbols]
