Description

  TECHNICAL FIELD The present invention relates to a foundation penetration and a pipe embedded so as to penetrate through a concrete foundation and a fixing method thereof.

  Conventionally, when a sleeve bend pipe embedded in a concrete foundation is fixed in a concrete formwork, the outer peripheral surface of the sleeve bend pipe is wound with a wire, and the other end of the wire is used as a reinforcing bar for concrete reinforcement. It was tightly connected (patent document 1).

  However, in such a fixing method, since the sleeve bend pipe cannot be sufficiently held by the wire, it is difficult to position the sleeve bend pipe, and the sleeve bend pipe is fixed by the pressure of the concrete or the vibration at the time of air bleeding when placing the concrete. There was a fear of slipping.

  Therefore, in recent years, a method of fixing the sleeve bend pipe and the reinforcing bar using a fixing holder in which a supporting part for fixing the reinforcing bar and a circular holder part are integrally formed has been adopted (patents). (Refer to paragraph 16 of Document 2).

  However, since the above-mentioned fixed holder sets a circular holder portion on the outer peripheral surface of the sleeve bend tube, the portion where the cross section is not circular, such as a bent sleeve bend tube or a protruding portion, is formed. In some cases, it is difficult to fix the sleeve bend pipe to the bar arrangement unless the holder section can be set and the bar arrangement for fixing the support section is not near the location where the sleeve bend pipe is to be installed. It was.

Also, as shown in Patent Document 3, a method of supporting a sleeve bend pipe by a support leg erected on a base plate has also been proposed. However, since the number of parts is large, the method becomes expensive and the workability is also good. Therefore, it was not sufficient for practical use.
Japanese Patent Laying-Open No. 2005-083127 JP 2006-214140 A JP 2002-322701 A

  The present invention has been made in view of the above problems, and the problem to be solved is to fix at a desired position with a wire without being restricted by the positional relationship between the bar arrangement and the sheath and the pipe. It is an object of the present invention to provide a foundation penetration and pipe that can be fixed without displacement of the position of the sheath due to the pressure of concrete pouring and vibration during air bleeding and a fixing method thereof.

  In order to achieve the above object, the foundation penetration sheath according to the present invention is a sheath pipe embedded so as to penetrate the concrete foundation of a building, and is disposed in the concrete foundation on the upper outer wall surface of the sheath pipe. A wire holding part for restricting the movement of the wire wound to connect the arranged reinforcing bar and the sheath is provided.

  In the basic penetrating sheath or tube of the present invention, the wire holding portion is a substantially U-shaped body comprising a pair of upper and lower support legs protruding from the upper outer wall surface of the sheath and a connecting rod connecting the support legs. It is preferable that it is a recessed part provided in this connecting rod, or a recessed part formed by two or more convex parts. Further, the wire holding portion has a substantially T-shape formed by a rod body protruding from the upper outer wall surface of the sheath and a wire locking piece formed integrally with the rod body and orthogonal to the rod body. Saddle tube or wire holding part is a basic through-hole or pipe or wire holding part which is a groove formed by a circumferential concave groove or two or more circumferential ridges provided on the upper outer wall surface of the sheath pipe However, it is preferable to use a base penetration or tube that is a through-hole provided in a plate projecting from the upper outer wall of the sheath, and a plurality of foundation penetrations or tubes provided with a plurality of wire holding portions at the same height. preferable. Furthermore, it is preferable to attach a scale indicating the height difference from the upper portion of the sheath tube in the vicinity of the wire retaining portion, and it is more preferable that the wire retaining portion is provided on the lower outer wall surface of the sheath tube.

  On the other hand, in the foundation penetration and pipe fixing method of the present invention, any of the above foundation penetrations and pipes are arranged in a concrete foundation mold, and are arranged in the wire holding part of the sheath and the concrete foundation. It is characterized in that the reinforcing bar is tightly connected with two or more places with a wire, and the foundation penetration and the pipe and the reinforcing bar are connected and fixed.

  The foundation penetration and pipe of the present invention are provided with a wire holding portion for restricting the movement of the wire wound to connect the reinforcement arranged in the concrete foundation and the sheath pipe on the upper outer wall surface of the sheath pipe. Therefore, the sheath tube is connected and fixed to the reinforcing bar simply by tightening the wire to the wire holding portion, and is not displaced by the pressure at the time of placing concrete or the vibration at the time of bleeding. Further, since the sheath tube can be fixed at a desired position by freely changing the length of the wire, the positional relationship between the bar arrangement and the sheath tube is not restricted. As described above, since the basic penetration and the pipe of the present invention are fixed using a wire, the cost can be minimized without using an extra member such as a fixing holder.

  The wire holding portion is a concave portion provided in the connection rod of a substantially U-shaped body composed of a pair of upper and lower support legs protruding from the upper outer wall surface of the sheath tube and a connection rod connecting the support legs. Alternatively, the basic penetration or tube, which is a recess formed by two or more projections, can be easily obtained by winding a wire around the recess provided on the connecting rod or the recess formed by two or more projections, The tube and the bar arrangement can be connected and fixed easily and firmly.

  Further, the wire holding portion has a substantially T-shape formed by a rod body protruding from the upper outer wall surface of the sheath and a wire locking piece formed integrally with the rod body and orthogonal to the rod body. The sheath and the reinforcing bar can be connected and fixed in the same manner as described above only by tying the wire to a wire locking piece orthogonal to the rod body and fastening the sheath.

  Similar to the above, the wire holding part is also a through hole provided in the plate body protruding from the upper outer wall surface of the sheath tube, and the basic penetration and tube are also tightened by winding the wire around the through hole provided in the wall surface. In addition, the sheath and the bar arrangement can be connected and fixed.

  Furthermore, the basic through-hole and the pipe in which the wire holding part is a circumferential concave groove provided on the upper outer wall surface of the sheath or a groove formed by two or more circumferential ridges are also provided on the outer side of the sheath pipe. The sheath and the bar arrangement can be connected and fixed in the same manner as described above only by winding a wire around a groove formed on the wall surface or a groove formed by two or more ridges.

  In addition, the foundation penetration and pipes with multiple wire holding parts provided at the same height position increase the number of tight spots by providing multiple wire holding parts, making it easier to fix the sheath pipe at the desired position. Furthermore, since an equal force is applied to the wire by providing them at the same height, the sheath and the tube and the bar arrangement can be more firmly connected and fixed.

  In particular, the foundation penetrating pipe with a scale indicating the height difference from the top of the sheath pipe in the vicinity of the wire holding part can know the distance from the concrete foundation to the sheath top, so it is accurate. The sheath tube can be connected and fixed to the reinforcing bar at the height position.

  In addition, the foundation penetrating pipe or the pipe provided with the wire holding part on the lower outer wall surface of the sheath pipe is provided with the wire holding part on the lower outer wall surface of the sheath pipe, thereby increasing the tightness of the wire. The sheath and the bar arrangement can be connected and fixed.

  On the other hand, since the basic penetration and tube fixing method of the present invention is connected to the reinforcement using a wire, the sheath tube can be arranged at a desired position if the length of the wire is freely changed, Since unnecessary members such as a fixed holder are not required, the cost can be minimized. In addition, the sheath pipe is tightly connected to the reinforcement bar at two or more locations using the sheath pipe having the above-described effects, so that the sheath pipe is firmly connected and fixed to the reinforcement bar due to the pressure at the time of placing concrete and the vibration at the time of bleeding. There will be no deviation.

  Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.

  1 is a perspective view showing a basic penetration or tube according to an embodiment of the present invention, FIG. 2 is a right side view of the same or tube, FIG. 3 is a plan view of the same or tube, and FIG. 4 is a wire holding of the same or tube. FIG. 5 is a partially cutaway sectional view showing an example of construction of the same pipe, and FIG. 6 is a perspective view showing an example of a fixing method for the pipe.

  As shown in FIG. 5, the foundation penetration sheath S1 (hereinafter simply referred to as sheath tube) of the present invention is embedded so as to penetrate the concrete foundation B of the house, and a 90 ° elbow joint 8 is provided in the internal space. It is housed and used to connect the upstream drain pipe 6 and the downstream drain pipe 7.

As shown in FIG. 1 and FIG. 2, the sheath tube S <b> 1 includes a horizontal side or tube portion 2, a length or tube portion 1 erected vertically from the side or tube portion 2, and a length or tube portion 1. 3 is formed by integrally forming a plurality of substantially U-shaped bodies 3c provided on the side and the tube part 2 and a wire holding part 3 provided on the connecting rod 3b of the substantially U-shaped body 3c. As shown in FIG. 4, the vertical length and the cross-sectional shape of the opening of the tube portion 1 are formed to be a front rear circular shape.
The sheath tube S1 may be integrally formed after the sheath tube S1 is formed in a state in which the sheath tube S1 is divided into a length, a tube portion 1 and a width or a tube portion 2 in terms of productivity, moldability, and the like. .

The vertical length and the length of the opening of the pipe portion 1 are preferably formed so as to be shorter than the entire length of the 90 ° elbow joint 8 accommodated inside. It is formed in a size that cannot be inserted into the sheath 1. As described above, when the vertical shape and the cross-sectional shape of the space of the pipe portion 1 are not circular but the front rear circular shape, the 90 ° elbow joint 8 can be easily accommodated in the vertical length and the pipe portion 1, and Since the length dimension can be shortened, the arrangement can be made even when the interval between the reinforcing bars 5 is narrow. Therefore, it is not necessary to cut a part of the reinforcing bars 5, and a decrease in strength of the concrete foundation B can be prevented.
In addition, it is desirable to arrange the vertical portion and the pipe portion 1 with the rectangular portion facing the outside (downstream side) of the building for the convenience of piping.

  As shown in FIGS. 1 and 5, the horizontal section and the pipe section 2 are cylinders having an inner diameter sufficient to allow the downstream side drainage pipe 7 to be inserted therein, and are cut in accordance with the dimensions of the concrete foundation B at the construction site. Therefore, it is formed to be longer than the concrete foundation B so as to protrude from the normally assumed concrete foundation B.

  As shown in FIG. 1, a concave wire holding portion 3 provided in each of the vertical and tubular portions 1 and 2 and the tubular portion 2 includes a pair of supporting leg portions 3a and 3a and the supporting leg portions 3a and 3a. A substantially U-shaped body 3c composed of connecting rods 3b that connect each other is provided on the connecting rod 3b, and is wound to connect the reinforcing bar 5 disposed in the concrete foundation B and the sheath tube S1. It is provided to restrict the movement of the attached wire 4 and hold the wound wire 4 so as not to shift.

  Since the support leg 3a constituting the wire holding part 3 has a provision that the cover thickness of the reinforcing bar is 4 cm or more in the “Building Standard Law Enforcement Ordinance”, the support leg 3a is configured to satisfy this condition. It is formed so as to protrude at least 40 mm or more from the vertical portion or the tube portion 1. Thus, when the supporting leg 3a protrudes 40 mm or more from the vertical length or the tube portion 1, the substantially U-shaped body 3c is arranged so as not to contact the reinforcing bar 5 and the above-mentioned legal conditions are satisfied. It becomes. Further, if the distance between the support legs 3a, 3a is too narrow, the sheath tube S1 may not be fixed at a desired position, so the gap is formed with an interval of about 50 mm.

  As shown in FIG. 4, a scale 36 (in this embodiment, in units of 5 mm) is attached to the connecting rod 3b for connecting the support legs 3a, 3a to each other to indicate the height difference from the top of the sheath tube S1. Yes. As described above, when the scale 36 indicating the height difference is attached in the vicinity of the wire holding portion 3, the distance from the upper surface of the concrete foundation B to the sheath S1 upper end can be known. The tube S1 can be connected and fixed to the reinforcing bar 5. Therefore, it is particularly preferable to attach a scale 36 for displaying the height difference in the vicinity of the vertical length or the wire holding portion 3 provided in the tube portion 1. If a scale 36 for adjusting the length is added in the vicinity, the distance of the sheath S1 from the outer wall of the concrete foundation B can be measured, so that the workability is improved.

As shown in FIG. 4, the connecting rod 3 b is provided with five concave wire holding portions 3. The concave wire holding portion 3 is formed by cutting the inner side of the connecting rod 3b into a semicircular shape and does not perform its function unless the wire 4 can be fastened. . Further, if the distance between the concave wire holding part 3 and the concave wire holding part 3 becomes too wide, it may be difficult to fix the desired position. The distance between the wire holding portions 3 is about 5 to 10 mm.
The concave wire holding portion 3 functions as a wire holding portion if at least one is formed on the connecting rod 3b. However, if about three to ten are formed, the wire is wound depending on the situation of the construction site. By selecting the wire holding part to be attached, the height at which the sheath S1 is installed can be freely set, which is preferable.
In addition, the concave wire holding portion 3 of the present embodiment is formed by cutting the connecting rod 3b into a semicircular shape, but is not limited to this shape as long as the wire 4 can be tightly coupled. For example, as shown in FIG. 7A, the outer peripheral surface of the connecting rod 3 b may be scraped to reduce the diameter, and this may be used as a concave wire holding portion 30 for fastening the wire 4.
Further, as shown in FIG. 7 (b), the connecting rod 3b is provided with a plurality of convex portions 3d, and the wire 4 is fastened to the concave wire holding portion 31 formed between the convex portions 3d and 3d. You may make it do.

  As shown in FIG. 1 and FIG. 3, the substantially U-shaped body 3 c provided with the concave wire holding part 3 has two on the vertical side and the side of the pipe part 1 and 2 on the side of the side and the pipe part 2. A total of five are provided, one on the side and the upper part of the pipe part 2. The concave wire holding part 3 provided in the vertical part or the pipe part 1 is for connecting and fixing the reinforcing bar 5 and also for adjusting the height of the sheath S1. Therefore, the substantially U-shaped bodies 3c, 3c (the connecting rods 3b, 3b) provided with the concave wire holding part 3 have the same height so that they can be connected most firmly when they are connected and fixed to the reinforcing bar 5. Now, they are provided in a relative positional relationship (a facing relationship with an interval of 180 °). Further, when the sheath S1 is connected and fixed, the positional relationship in which the wire 4 extends from the bar arrangement 5 in the vertical direction and the wire 4 and the ground are parallel to each other is most difficult to shift. The height position of the reinforcing bar 5 varies depending on the construction site, and the wire holding part 3 having a concave shape of the pipe part 1 is provided so that the wire 4 can be pulled out in parallel with the ground from the reinforcing bar 5 having different height positions. The provided connecting rod 3b is formed in the vertical direction, and the support leg portions 3a, 3a for connecting the connecting rod 3b protrude from the vertical or outer wall surface of the tube portion 1 in a paired relationship. The concave wire holding portion 3 is provided in a vertical direction on a connecting rod 3b formed in the vertical direction.

On the other hand, the wire holder 3 having a concave shape on the side and the tube portion 2 does not adjust the height of the sheath tube S1, but plays a role of adjusting the width of the sheath tube S1 from the outer surface of the concrete foundation B. Since it is large, the connecting rod 3b provided with the concave wire holding portion 3 is formed in the horizontal direction, and the supporting leg portions 3a, 3a for connecting the connecting rod 3b have a horizontal or pipe portion in a pair of front and rear positions. 2 protrudes from the outer wall surface. The concave wire holding portion 3 is provided in a horizontal direction on a connecting rod 3b formed in the horizontal direction. The connecting rods 3b and 3b of the substantially U-shaped bodies 3c and 3c provided on the side of the horizontal part or the pipe part 2 have the same distance from the horizontal side or the outflow side tip of the pipe part 2 and the relative positional relationship ( The upper connecting rod 3b is located at the middle position (90 ° interval from the side connecting rod 3b) between the connecting rods 3b, 3b provided on the side. Provided (even if it is 90 ° apart from the side connecting rod 3b, even if the connecting rod 3b is provided on the side or the lower portion of the tube portion 2, the workability of tightening the wire is poor, and the sheath tube S1 It is not effective because it does not play a sufficient role to hold When the wire holding part 3 and the bar arrangement 5 provided on the connecting rod 3b are connected and fixed by the wire 4, the connecting rod 3b on the side and the upper portion of the tube portion 2 is connected at three points rather than two points. However, it may be omitted depending on circumstances.
When the sheath S1 is more firmly connected and fixed, a substantially U-shaped body 3c is formed also in the longitudinal direction and the rear portion of the tube portion 1, and the wire holding portion 3 is provided on the substantially U-shaped body 3c. That's fine.

  The sheath S1 having the above-described configuration is not particularly limited in terms of dimensions, materials, and the like, but the length and length of the opening of the tube portion 1 are 50 mm to 250 mm, the height is 200 mm to 400 mm, the width and the tube portion 2 Those having a length of 120 mm to 400 mm and an inner diameter of 50 mm to 125 mm are preferably used. In view of strength, durability, and moldability, it is desirable to use a synthetic resin, and a hard vinyl chloride resin is particularly preferably used.

  Next, a method for fixing the sheath tube S1 to the reinforcing bar 5 will be described.

  As shown in FIG. 5 and FIG. 6, a reinforcing bar 5 for improving the strength of the concrete foundation B is disposed in a formwork (not shown) used for forming the concrete foundation B, and formed by the reinforcing bar 5. In the space thus formed, the sheath tube S1 is arranged so as not to interfere with the reinforcing bar 5. And after carrying out exact height adjustment and width adjustment, one end of the wire 4 is formed into a concave wire holding portion of the substantially U-shaped bodies 3c, 3c provided on the length of the sheath S1 or on the side surface of the tube portion 1. The other end is tightly coupled to the reinforcing bar 5 in the vicinity of the wire holding portion 3 (in this embodiment, the reinforcing bar 5 extending in the front-rear direction). At this time, as described above, since the wire 4 extends in the vertical direction from the bar arrangement 5 without the wire 4 slackening and the wire 4 and the ground are parallel to each other, these conditions are satisfied. The recessed wire holding part 3 is selected, and the wire 4 is fastened to the recessed wire holding part 3. The wire 4 used for connecting the sheath S1 and the reinforcing bar 5 may be any wire as long as it is generally distributed in the market. However, in consideration of workability, strength, etc., the outer diameter is 0.5. Those having a size of about 2 mm are preferably used.

  Next, concave wire holding portions 3 and 3 of the substantially U-shaped bodies 3c and 3c provided on the side of the sheath S1 and on the side of the tube portion 2, and the bar arrangement 5 in the vicinity of the wire holding portion 3 ( In the present embodiment, the reinforcing bar 5) that is inclined obliquely is connected by a wire 4. At this time, since the reinforcing bar 5 extending in the left-right direction and the wire 4 are preferably in a parallel relationship, the wire 4 is fastened to the concave wire holding portion 3 that satisfies these conditions so that the wire 4 does not loosen. To do. Then, the concave wire holding portion 3 of the substantially U-shaped body 3 c provided on the top of the horizontal portion or the tube portion 2 and the bar arrangement 5 in the vicinity thereof are tightly connected by the wire 4.

  As described above, the concave wire holding portions 3 and 3 of the substantially U-shaped bodies 3c and 3c provided on the side surface of the sheath S1 and the side of the sheath 2 When a total of five locations of the recessed wire holding portions 3, 3 and 3 of the substantially U-shaped bodies 3c, 3c and 3c provided are fastened together with the wire 4 and fixedly connected to the reinforcing bar 5, the concrete is placed during concrete placement. The sheath S1 is not displaced by the pressure of the air and the vibration at the time of bleeding.

As described above, when the sheath pipe S1 and the reinforcing bar 5 are firmly connected and fixed, the concrete is placed in the concrete formwork to form the concrete foundation B. When the concrete foundation B is completed, next, the 90 ° elbow joint 8 is accommodated in the inner space of the sheath pipe S1, the downstream drainage pipe 7 is connected to the connection port at the lower end portion, and the connection port at the upper end portion is connected. The upstream drainage pipe 6 into which the drainage from the indoor drainage facility flows is connected via the height-adjusted vertical pipe 9 and the 90 ° elbow joint 8. Then, the downstream drain pipe 7 is completed by connecting to the outdoor drain pipe via the 90 ° elbow joint 8, the short pipe 10, and the 90 ° elbow joint 8.
When the height of the concrete foundation B is higher than the height of the pipe S1, the height adjustment may be performed by connecting an adjuster (not shown) for adjusting the height or the pipe portion 1 to the height.

  As is clear from the above description, the basic penetration and pipe S1 of the present invention and its fixing method are such that the wire holding part 3 and the reinforcing bar 5 of the sheath pipe S1 are firmly connected and fixed at a total of five locations, and the concrete is placed. There will be no deviation due to the pressure at the time or vibration at the time of bleeding. Further, if the length of the wire 4 is freely changed, the sheath S1 can be arranged at a desired position, and the normal wire 4 is used without using an extra member such as a fixed holder, so that the cost can be minimized. Can also be suppressed.

  8A and 8B are partial views of a basic penetration and a wire holding part of a tube according to another embodiment of the present invention, in which FIG. 8A is a partial plan view showing the wire holding part of the sheath and FIG. FIG.

  The sheath tube S2 of the present embodiment is also composed of the same length, tube portion 1 and lateral portion and tube portion 2 as the sheath tube S1 described above. As shown in FIG. A plurality of through-holes 32 are provided in the plate body 32a that protrudes and extends in the up-down direction, and is formed at regular intervals.

The plate body 32a provided with the vertical length and the upper outer wall surface of the tube portion 1 and provided with the through hole 32 protrudes about 40 mm from the vertical wall surface and the outer wall surface of the tube portion 1, and is about 1 to 5 mm in the vertical direction. A total of five through holes 32 are provided at regular intervals.
The sheath tube S2 of the present embodiment is configured to regulate and hold the movement of the wound wire 4 by winding the wire 4 around any of the five through holes 32. The shape of the through hole 32 may be simply a rectangle or a circle. However, as shown in FIG. 8, the substantially triangular through hole in which the outward side of the sheath is a small radius, or the inward and outward side of the sheath is small. It is preferable to use an elliptical through hole (not shown) having a round shape. Thus, when the shape on the side around which the wire 4 is wound is a small rounded shape, the movement of the wound wire 4 is more restricted and the wire 4 is not easily displaced.
Further, it is preferable to provide a plurality of through holes 32 that protrude in the same manner from the side wall and the lower outer wall surface of the tube portion 2 and extend in the front-rear direction at a predetermined interval. Since it is the same as the plate body 32a provided with the through-hole 32 provided in the length and the pipe part 1, description is abbreviate | omitted.

The sheath tube S2 is also connected and fixed by winding the wire 4 around the through hole 32 formed in the plate body 32a.
Since the foundation penetration, other structures of the tube S2, and the fixing method are the same as those of the embodiment of the foundation penetration and the tube S1, the description is omitted.

  The sheath S2 having the above-described configuration is not likely to be displaced due to the pressure of the concrete or the vibration at the time of air release, like the sheath S1 described above.

  FIG. 9 is a right side view showing a basic penetration and a pipe according to still another embodiment of the present invention.

  The sheath tube S3 shown in FIG. 9 is also composed of the same length, tube portion 1 and lateral portion and tube portion 2 as the sheath tube S1 and sheath tube S2 described above. A plurality of wire holding portions 33, which are circumferential concave grooves, are provided at regular intervals on the outer wall surface and the lateral or lower outer wall surface of the tube portion 2.

The wire holding part 33 of the circumferential concave groove provided in the upper outer wall surface of the said length or the pipe part 1 is the width | variety and depth of about 1-5 mm formed so that the wire 4 could be inserted, A total of five wire holding portions 33 having parallel grooves are provided in the vertical direction with a constant interval of about 1 to 5 mm. Further, the circumferential and grooved wire holding portion 33 provided on the outer wall surface of the lower side of the tube or the tube portion 2 has the same width and depth as the wire holding portion 33 of the groove or the recessed groove provided on the tube portion 1 described above. There are a total of five wire holding portions 33 each having a concave groove perpendicular to the ground in the left-right direction with a constant interval of about 1 to 5 mm.
In addition, it cannot be overemphasized that the width | variety, the depth, and the number of the wire holding | maintenance part 33 of this ditch | groove can be suitably changed with a construction site. Further, as described above, the wire holding portion 33 of the concave groove is not necessarily required to be a uniform concave groove on the entire circumference. If the sheath S3 and the reinforcing bar 5 can be firmly connected and fixed, the wire holding portion 33 is circumferentially formed. The wire holding part 33 may be formed as a discontinuous groove (not shown).

The sheath tube S3 is fastened by winding the wire 4 around the wire holding portion 33 having a circumferential groove. At this time, two wires 4 may be wound around the wire holding portion 33 in the concave groove at the same position, and the respective wires 4 and 4 may be tightly connected to the reinforcing bar 5. It is more workable to wind one end in advance and connect one end to the reinforcing bar 5 and connect the other end to the reinforcing bar 5 to connect and fix the sheath S3 and the reinforcing bar 5.
Since the foundation penetration and other structures and fixing methods of the tube S3 are the same as those of the embodiment of the foundation penetration and the tube S1 shown in FIGS.

  The sheath pipe S3 having the above-described configuration is also firmly connected and fixed to the reinforcing bar 5 (total of four places), similarly to the sheath pipe S1 described above. There is no worry.

  FIG. 10 is a right side view showing a basic penetration and a pipe according to still another embodiment of the present invention.

  As shown in FIG. 10, the sheath tube S <b> 4 of the present embodiment is composed of the same length, tube portion 1, width and tube portion 2 as the sheath tube S <b> 1 and sheath tube S <b> 3 described above. A plurality of circumferential ridges 34a are provided at regular intervals on the upper outer wall surface and the lateral or lower outer wall surface of the tube portion 2, and a wire holding portion 34 which is a groove between the circumferential ridges 34a and 34a. Is formed.

The circumferential protrusion 34a provided on the vertical outer wall surface of the pipe portion 1 is formed on the outer wall surface of the vertical pipe portion 1 with a length or 1 mm protruding from the outer wall surface of the pipe portion 1. Thus, a total of six ridges 34a in parallel with the ground are provided at regular intervals of about 1 to 5 mm in the vertical direction. The sheath tube S4 of the present embodiment winds the wire 4 around one of the wire holding portions 34 that are five grooves having a height of about 1 to 5 mm formed between the ridge 34a and the ridge 34a. To hold. Further, a total of six circumferential ridges 34a provided on the side wall and the lower outer wall surface of the pipe portion 2 are provided in the front-rear direction so as to be perpendicular to the ground. The interval between them is the same as the length and the ridge 34a provided in the tube portion 1, and therefore the description thereof is omitted.
The circumferential ridges 34a, 34a forming the wire holding portion 34 do not necessarily have to be provided uniformly on the entire circumference, and if the sheath S4 and the reinforcing bar 5 can be firmly connected and fixed, the circumferential projections 34a, 34a are not circumferential. A groove formed by the continuous protrusions 34a and 34a may be used as the wire holding portion 34 (not shown). (By positioning the knot of the tightly connected wire 4 at the portion where the ridges 34a, 34a are interrupted, the wire is more difficult to shift.)

The sheath tube S4 is also fastened by winding the wire 4 around the wire holding part 34 which is a groove formed between the ridge 34a. At this time, it is preferable to connect the two reinforcing bars 5 and 5 with one wire 4 as in the case of the sheath S3 described above.
Since the basic penetration and other structures of the tube S4 and the fixing method are the same as those of the embodiment of the basic penetration and the tube S3 shown in FIG. 9 described above, description thereof will be omitted.
