Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe bed rest capable of securely supporting a plurality of conduits when the conduits are buried underground.

[0002]

2. Description of the Related Art Japanese Utility Model Publication No. 59-13418 proposes a bed rest for piping used when burying a conduit tube underground. However, this piping bed rest had some problems in workability. That is, in this conventional piping pillow, since the upper and lower pillows and the left and right pillows are connected by the connecting pins, the work of connecting the upper, lower, left and right pillows at the piping construction site is complicated. Sometimes it took time. In addition, this pillow base has a key-shaped ridge and a notch on the lower surface, and a pair of upper and lower pillows are connected by the key-shaped ridge and the notch, so that the ground may be subsided due to an earthquake or the like. In this case, there is a problem that the bed rest is easily moved in the axial direction of the conduit tube.

The present invention has been made to solve such a problem, and the construction work at the site can be performed easily and reliably, and the conduits and the like set up in a plurality of upper and lower stages can be securely connected without any displacement. An object of the present invention is to provide a pipe bed rest that can be supported.

[0004]

According to the present invention, there is provided a base having a semicircular pipe receiving portion on an upper surface of a base, and recesses and projections which can be mutually fitted at opposite positions on both sides of the upper surface. A pillow provided with recesses and protrusions that can be fitted to each other on both sides of the base, and provided with a slide groove extending in the width direction on the lower surface of the base, and a semicircular pipe on the upper surface of the base. A pillow bed having a receiving portion, a recess and a protrusion that can be fitted to each other at opposite positions on both sides of the upper surface thereof, and a ridge provided on a lower surface of the base so as to be fitted with a slide groove of the pillow bed. It is characterized by consisting of.

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a front view showing one pillow bed of the present invention, FIG. 2 is a plan view of this one pillow bed, FIG. 3 is a perspective view showing a state where one set of pillow beds is combined, and FIG. FIG. 5 is a front view showing a state in which a set of pillows is assembled up and down, and FIG. 6 is a perspective view of a main part of the pillows showing another embodiment of the present invention. In the figure, reference numeral 1A denotes one pillow bed, 2A denotes the other pillow bed, and these pillow beds 1A and 2A are formed of synthetic resin such as vinyl chloride resin, FRP, waste plastic, or the like.

The pillow base 1A has a semicircular tube receiving portion 11 on the upper surface of a rectangular base 1, and a recess 12a and a projection 12b that can be fitted to each other at opposite positions on both sides of the upper surface. Is provided. That is, as shown in FIG.
When the other bed rest 1A is turned upside down and placed on
The depression 12a and the projection 12b of each pillow base 1A are fitted and connected. Further, a concave portion 13a and a convex portion 13b are provided on both side surfaces of the base 1 so as to be fitted to each other, and as shown in FIG.
The concave portions 13a and the convex portions 13b of A and 1A are fitted and connected. Further, a slide groove 14 extending in the width direction is provided on the lower surface of the base 1.

The pillow base 2A has a semicircular tube receiving portion 21 on the upper surface of a rectangular base 2, and a recess 22a and a protrusion 22b which can be fitted to each other at opposite positions on both sides of the upper surface. Is provided. That is, as shown in FIG. 4 and FIG. 5, when the other bed 2A is placed upside down on one bed 2A, the depression 22a and the projection 22b of each bed 2A are turned upside down.
Are fitted and connected. Further, a protrusion 24 extending in the width direction is provided on the lower surface of the base 2 so that the protrusion 24 can slide by fitting into the slide groove 14 provided on the lower surface of the pillow base 1A. Has become.

[0008] The conduit tube P using the above-mentioned bed rests 1A and 2A.
When laying the pillows, the pillows 1
Lay A. At this time, the adjacent left and right pillow beds 1A,
The concave portion 13a and the convex portion 13b of 1A are slidably fitted and connected. Then, the conduit tube P is placed on the tube receiving portion 11 of each of the pillows 1A, and the inverted pillows 1A are placed thereon, and the depressions 12a and the projections 12b of the upper and lower pillows 1A, 1A are placed. Are fitted and combined.

Next, the pillow stand 2A is placed on the upper surface of the set of pillow stands 1A, 1A and assembled. At this time, as shown in FIG. 3, the other pillow base 2A is positioned beside the one pillow base 1A, and the protrusions 24 provided on the lower surface of the pillow base 2A are fitted into the slide grooves 14 of the pillow base 1A. Slide together. In this manner, the pillow tables 2A are sequentially set on the pillow tables 1A, and then the conduit pipes P are placed on the tube receiving portions 21 of the respective pillow tables 2A, and the inverted pillow tables 2A are placed thereon. Are mounted, and the depressions 22a and the projections 22b of the upper and lower pillow beds 2A, 2A are fitted and combined. By repeating this operation sequentially, the conduits P are laid over a plurality of upper and lower stages, and finally backfilling of earth and sand is performed.

In the above-described embodiment, an example is shown in which the slide groove 14 is provided continuously over the entire lower surface of the base 1 in the width direction, but the present invention is not limited to this. For example,
As shown in FIG. 6, the slide groove 14 and the ridge 24 are partially provided, and the ridge 2 is formed in the through hole 14 a communicating with the slide groove 14.
4 may be inserted and then slide-fitted. FIG. 5 shows a pair of upper and lower pillow beds 1A, 1A,
Although the one on which a pair of pillow beds 2A, 2A of the same size is placed is illustrated, the pillow beds 1A, 2A can be of any size according to the outer diameter of the power pipe to be laid.

[0011]

As described in detail above, the use of the pillow stand of the present invention makes it possible to easily and reliably connect the upper, lower, left and right pillow stands. Further, in the present invention, the ridge provided on the other pillow is fitted into the slide groove in the width direction provided on one of the pillows, so that the upper, lower, left and right pillows can be used even when the ground subsides due to an earthquake or the like. It is possible to reliably support a plurality of conduits without displacement between comrades.
