DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe spacer having a plurality of supporting portions for supporting a plurality of pipes buried underground or the like.

[0002]

2. Description of the Related Art A large number of pipe spacers have been proposed which support an installed pipe by sandwiching the pipe between an upper split member and a lower split member which are vertically divided into two. Since the pipe spacers support one pipe, in order to support a large number of pipes, the pipe spacers supporting the pipes must be connected to each other by a connecting tool or the like, and parts are required. Not only does the number of pipe spacers increase, but the work of connecting the pipe spacers becomes more troublesome and troublesome as the number of pipe spacers increases, and there is room for improvement.

In order to eliminate the need for connecting the pipe spacers to each other, a plurality of through-holes having dimensions equal to or larger than the external dimensions of the pipe are formed in a rectangular and plate-like member. Tube spacers have been proposed.
Since this pipe spacer penetrates the pipe through each through hole in the pipe axis direction, when the pipe length becomes long, it is supported by a large number of pipe spacers from one end to the other end of the pipe. In this case, since the distance of the tube through the through hole of the tube spacer becomes longer in proportion to the length, the operation of penetrating the tube into the tube spacer is very time-consuming and troublesome.
Further, in this case, since the frictional force with the through hole acts on the pipe when the pipe is penetrated through the pipe spacer, the penetrating work cannot be performed smoothly, and the penetrating work itself takes much time, and the above-mentioned inconvenience is further remarkable. It is to be. If the size of the through-hole is made larger than the outer dimensions of the pipe so that the above-mentioned penetrating operation can be performed quickly, the pipe spacer may unexpectedly move in the pipe axis direction with respect to the pipe after the penetrating operation. In this method, the size of the through hole must be substantially the same as the external size of the pipe, and the above-mentioned disadvantage cannot be solved.

[0004]

SUMMARY OF THE INVENTION In view of the foregoing, it is an object of the present invention to provide a tube spacer which can easily and quickly support a tube.

[0005]

In order to solve the above-mentioned problems, the present invention comprises a plurality of support portions for supporting a plurality of pipes at predetermined intervals, respectively, wherein It has an inner diameter substantially equal to the outer diameter of the pipe, and has a receiving surface for supporting an outer peripheral portion that exceeds half of the outer peripheral part of the pipe. An opening for insertion from a direction intersecting with the axial direction is formed from a side wall having an opening formed therein, the opening having a size smaller than the outer diameter of the tube, and the opening being inserted into the opening by inserting the tube into the opening. The side wall is configured so that the side wall can be elastically deformed so as to be expanded so that the portion is enlarged, and can be restored to a state before the elastic deformation after insertion. Therefore, when a plurality of tubes are supported by the tube spacers, the tubes are pushed into the support portions while the side walls are elastically deformed to the outside expansion state by inserting the plurality of tubes into the openings of the plurality of support portions. It is. After the insertion of the tube, the side wall is restored to the state before the elastic deformation and the tube is prevented from moving out of the support portion, and the outer peripheral portion exceeding half of the outer peripheral portion of the tube is used as the receiving surface. Thus, the supported state can be maintained reliably.

The opening width of the opening is set to 70, which is the outer diameter of the tube.
When the content is in the range of% to 85%, good results can be obtained in both the ease of insertion of the tube and the effect of retaining the tube.

[0007] The upper portion of the upper row connected in a plurality of left and right directions, and the lower row connected to the lower side of the upper row and connected in a plurality of left and right directions, the opening of the upper row Are open upward, and the openings in the lower row are open downward, so that when the spacers are buried, the opening directions of these openings can be up and down. As compared with the case where the direction is the horizontal direction, the opening portion is less likely to be expanded outward due to the large vertical vibration particularly received from the ground, and the retaining function is enhanced.

[0008] The connection between the support parts comprises a plate-like connection part thinner than the thickness of the support part, and the surface of the connection part is parallel to the tube axis direction and the tube axis of the support part is parallel to the tube axis. If it is configured to connect one end in the direction, while the strength of the connecting portion can be increased so that the connecting portion is not easily deformed or damaged by the impact force generated when inserting the tube, By bending the support portions 3, 3 in the direction of arrow X shown in FIG. 6, the two support portions 3, 3 can be easily separated by the connecting portion 6, and the number of the support portions 6 can be easily reduced. Can be. In FIG. 6, the support portions 3 are vertically arranged.
Although the support portions 3 are separated from each other, the support portions 3 can be separated in the left-right direction.

[0009] The thickness of the connecting portion is set to one of the thickness of the supporting portion.
By setting the ratio to / 2 or less, the two support portions can be easily separated with a smaller operation force. And even if the two support parts are separated after being buried in the ground, it does not matter at all, but rather the positive separation of the support parts causes the vibrations of each pipe spacer to move. There are advantages that can be absorbed.

[0010] The pipe spacer is provided at each of the side end portions of the side wall with an opening at the rear end side in the pipe insertion direction with left and right guide walls, and free ends of the left and right guide walls. And an outer wall for connecting the portions to each other outside the side wall to form an outer frame of the side wall. By thus forming the tube spacer from an annular (loop-shaped) structure including the side wall, the left and right guide walls, and the outer wall, it is possible to increase the shape retention strength of the tube spacer while reducing the weight. In addition, when inserting the tube, the tube is pushed in while being in contact with the inclined guide surface, so that the end of the opening on the side wall can be smoothly expanded outward and elastically deformed, making it easier to insert the tube. It can be carried out.

[0011] An outer wall for forming an outer frame of the side wall is provided outside the side wall, and the inner surface of the outer wall is connected to the outer surface of the side wall except for an open end, whereby the weight can be reduced. However, the shape retention strength of the tube spacer can be increased, and the opening end of the side wall is easily elastically deformed outward when the tube is inserted, so that the tube can be inserted with a small operation force.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 1 to 3 show a tube spacer 2 capable of supporting a plurality of (in the figures, six, but any number of two or more) tubes. . The tube 1
Has alternately concave portions 1A and convex portions 1B on the outer surface, and
Although they are formed in a spiral shape, the concave portions 1A and the convex portions 1B may be annular or flat without the concave portions 1A and the convex portions 1B. The tube 1 is made of synthetic resin or synthetic rubber to provide flexibility, so that there is an advantage that vibration generated by an earthquake, land subsidence, or the like can be satisfactorily absorbed. Any material such as ceramic and concrete may be used.

As shown in FIGS. 1 to 6, the tube spacer 2 is connected to three support portions 3 capable of supporting the three tubes 1 at predetermined intervals in the horizontal direction. An upper support 4 connected to a lower side of the upper support 4,
In addition, the lower support portion 5 is connected to the three support portions 3 corresponding to the lower portions of the upper three support portions 3 respectively. Although the tube spacer 2 is made of a synthetic resin, the weight can be reduced. However, any material such as a metal or a synthetic rubber that can be elastically deformed and has a restoring force may be used. .

Each of the support portions 3 has an inside diameter substantially equal to the outside diameter of the tube 1 and supports a portion (about two-thirds) of the outer periphery of the tube 1 that exceeds half of the outer periphery. Opening 3K having surface 3a and capable of inserting tube 1 upward or downward
Formed on the upper side or the lower side wall 3A,
Left and right guide walls 3B, 3B having inclined guide surfaces 3b extending from the upper end or lower end of the side wall 3A, and an outer frame for covering the outside of the side wall 3A from the upper end or lower end of the guide walls 3B, 3B. And a substantially U-shaped outer wall 3C which constitutes the shape (1), so that the shape-retaining strength can be increased while reducing the weight. Then, the inner surface of the outer wall 3C and the side wall 3A
The first connecting plates 3D, 3D, 3D, which are parallel to the tube axis direction and have a length extending at both ends in the tube axis direction, in order to connect the outer surface of the tube at three points shown in the figure, A second connecting plate arranged in a posture orthogonal to the tube axis direction to connect the substantially central portion of the connecting plate 3D in the tube axis direction and the substantially central portions of the connecting plates 3D, 3D located at both ends in the tube axis direction. 3
The shape retention strength of the support portion 3 is further enhanced by E and 3E. The portions 3F, 3F shown in the figure are hollow, and as shown in FIG. 2, when the tube 1 is inserted into the support portion 3 from above, the guide walls 3B, 3B are in an outwardly expanding state (outwardly). Side) to be easily elastically deformed. And
When the tube 1 is inserted into the support portion 3 while the support portion 3 is elastically deformed, the support portion 3 returns to the original state before the elastic deformation by the restoring force, and the tube 1 can be held by the side wall 3A. . In the figure, the tube 1 is inserted into the support portion 3 from above and below. However, the tube 1 is inserted into the support portion 3 from above and below by arranging the opening 3A of the support portion 3 so as to be in the left and right direction. May be. By setting the opening 3A of the support portion 3 in the up-down direction, the opening 3A is unlikely to expand outside due to large vertical vibrations received from the ground after being buried, and it is possible to reliably prevent the opening 3A from falling off. For example, the support portion 3 can be constituted only of the thick and heavy side wall 3A, and the specific structure of the support portion 3 can be freely changed.

The connection between the support portions 3 is shown in FIGS.
As shown in the figure, the connection is performed by a plurality of plate-shaped connecting portions 6 having a thickness smaller than the thickness of the supporting portion 3, and each connecting portion 6 has a surface parallel to the tube axis direction. The support portion 3 is formed in such a length as to connect one end portion in the tube axis direction. The support portion 3 is bent in the direction of the arrow X shown in FIG. Thus, the number of the support portions 3 can be easily reduced. In the figure, the connecting portion 6 is approximately one third of the length of the supporting portion 6 in the tube axis direction.
However, by setting the length to be shorter than this, the two support parts 3 and 3 can be more easily separated, and by setting the length longer than this, it is easy to separate against the impact force. However, it can be changed as appropriate according to the thickness of the pipe 1 and the situation of the place where the pipe 1 is embedded.
By setting the thickness of the connecting portion 6 to be equal to or less than 厚 み of the thickness of the supporting portion 3, the two supporting portions 3 can be more easily separated.

The horizontal dimension of the opening 3K, that is, the opening width T (see FIG. 4) is determined by the outer diameter S of the tube 1 (see FIG. 3).
By setting the range of 70% to 85% of the range, the ease of insertion of the tube 1 and the effect of preventing the tube 1 from coming off can be exerted at substantially the same level. The effect of preventing the tube 1 from coming off increases as the distance approaches 70%, and the ease of insertion of the tube 1 increases as the distance approaches 85%. It will be adjusted within the range of ~ 85%.

The guide walls 3B may be omitted. That is, as shown in FIG. 7, the guide walls 3B, 3B are omitted, that is, the inner surface of the outer wall 3C and the portion of the outer surface of the side wall 3A other than the open end are connected to the two connecting plates 3D, 3D.
And one connecting plate 3E that fills the gap between the connecting plates 3D, 3D, thereby elastically deforming both ends of the side wall 3A, that is, the open ends, to the outside expanding state with the insertion of the pipe 1. There is an advantage that the tube 1 can be easily and quickly inserted with a small operation force. 7 shown in the figure
Are projections which are engaged with the recesses 1A of the tube 1 to prevent the tube 1 from moving in the tube axis direction. The projections 7 are integrated with the surface of the plate portion 8 formed by cutting out a part of the side wall 3A. Although formed, the projection 7 may not be provided. Note that members not described in the drawings are the same as those described above, and thus are denoted by the same reference numerals and description thereof will be omitted.

According to the first aspect of the present invention, the tube is pushed into the supporting portion and the tube is held by the supporting portion while the side wall is elastically deformed so as to expand outwardly, so that the through-hole is formed as in the prior art. The pipe can be supported easily and quickly, which is advantageous in terms of construction, as compared with the case where the pipe is passed through the hole. Further, after the tube is inserted, it is possible to maintain a state in which the outer peripheral portion that exceeds half of the outer peripheral portion of the tube is securely supported on the receiving surface without rattling.

According to the second aspect, when the opening width of the opening is in the range of 70% to 85% of the outer diameter of the tube, both the easiness of inserting the tube and the effect of preventing the tube from falling off are satisfactory. The result can be obtained, and it can be excellent in both the construction surface and the use surface.

In addition, when the spacer is buried by forming a plurality of lower rows connected in the left-right direction, the upper row opening is an upper opening type, and the lower row opening is a lower opening type. Since the opening direction of the opening can be set to the vertical direction, for example, compared to the case where the opening direction of the opening is set to the horizontal direction, the opening is less likely to expand outside due to large vertical vibration received from the ground in particular, and It is possible to provide a tube spacer that has a high stopping action and can be reliably held for a long period of time.

According to the fourth aspect, the connection between the support portions comprises a plate-like connection portion thinner than the thickness of the support portion, and the surface of the connection portion is parallel to the tube axis direction. If the support section is configured to connect one end in the pipe axis direction, the strength of the connection section is increased so that the connection section is not easily deformed or damaged by the impact force generated when inserting the pipe. However, just by bending the support part, the two support parts can be easily separated at the connecting part, the number of support parts can be easily reduced, and the number of pipe spacers of different types differs Many types of tube spacers can be easily and quickly constructed.

According to the fifth aspect, by setting the thickness of the connecting portion to be equal to or less than の of the thickness of the supporting portion, the two supporting portions can be easily separated with a smaller operation force.
Tube spacers with different numbers of supports can be configured more easily and quickly. And even if the two support parts are separated after being buried in the ground, it does not matter at all, but rather the positive separation of the support parts causes the vibrations of each pipe spacer to move. Can be absorbed,
Breakage of the tube spacer and the tube can be satisfactorily avoided.

According to the sixth aspect of the present invention, the pipe spacer is formed of an annular (loop-shaped) structure including a side wall, left and right guide walls, and an outer wall. The shape retention strength can be increased, and when inserting the tube, the tube is pushed in while being in contact with the inclined guide surface, so that the opening side end of the side wall smoothly spreads outward and elastically deforms In addition, the pipe can be easily inserted, and an excellent pipe spacer can be obtained on both the durable surface and the construction surface.

According to the seventh aspect, an outer wall for forming an outer frame of the side wall is provided outside the side wall, and the inner surface of the outer wall is connected to the outer surface excluding the open end of the side wall to reduce the weight. In addition, the shape retention strength of the tube spacer can be increased, and the opening end of the side wall is easily elastically deformed outward when the tube is inserted. Can be inserted with a small operating force, which is advantageous not only in durability but also in construction, as in the sixth aspect.
