又，在將連結銷半體22、23疊合之後時，如第4圖(c)所示，於連結銷的內部，形成內徑較小的中空部21a、和比該內徑還大的中空部21b，又，從第1突起部22d、23d起，由於連結銷之端部側(右側)的連結銷半體22、23的壁厚變得較薄，所以形成內徑比中空部21b更大的中空部21c。Further, when the coupling pin halves 22 and 23 are overlapped, as shown in Fig. 4(c), a hollow portion 21a having a small inner diameter is formed inside the coupling pin, and a larger diameter than the inner diameter is formed. In the hollow portion 21b, the thickness of the connecting pin halves 22, 23 on the end side (right side) of the connecting pin is made thinner from the first projections 22d and 23d, so that the inner diameter is larger than the hollow portion 21b. Larger hollow portion 21c.
分離銷24為圓柱狀的銷，係具有：圓錐狀的前端部24a、圓柱狀的前端部24b、圓柱狀的中央部24c、圓柱狀的後端部24d。The separation pin 24 is a cylindrical pin having a conical tip end portion 24a, a cylindrical distal end portion 24b, a cylindrical central portion 24c, and a cylindrical rear end portion 24d.
於第6圖圖示出將連結銷半體22、23疊合後所取得的連結銷21、分離銷24以及環片1之尺寸。The size of the joint pin 21, the split pin 24, and the loop piece 1 obtained by laminating the joint pin halves 22, 23 is shown in Fig. 6.
於環片1之側板103所形成的圓形插通孔103a的直 徑D2，是比鄰接於側板103之內部板106的圓形插通孔106a的直徑D1還更大，連結銷21其突出部22b、23b為具有預定的間隙可以通過內部板106的插通孔106a，又，半管狀部22c、23c為具有大致同樣的間隙可以通過側板103之插通孔103a的大小。連結銷21的第1突起部22d、23d，其***側(左側)為傾斜，具有只要強壓連結銷藉由彈性，就可以通過插通孔103a的高度(突出量)。又，連結銷21之第2突起部22e、23e，亦具有與突起部22d、23d左右對稱的同樣大小。Straight through hole 103a formed by the side plate 103 of the ring piece 1 The diameter D2 is larger than the diameter D1 of the circular insertion hole 106a adjacent to the inner plate 106 of the side plate 103, and the protruding portion 22b, 23b of the coupling pin 21 is a through hole having a predetermined gap through the inner plate 106. Further, the semi-tubular portions 22c and 23c have a size in which the substantially the same gap can pass through the insertion hole 103a of the side plate 103. The first projections 22d and 23d of the joint pin 21 are inclined on the insertion side (left side), and have a height (protrusion amount) through which the through hole 103a can pass through the strong pressure coupling pin by elasticity. Further, the second projections 22e and 23e of the coupling pin 21 have the same size as the left and right symmetry of the projections 22d and 23d.
從連結銷21之突出部22b、23b與半管狀部22c、23c的交界面S1起到第1突起部22d、23d之垂直面S2為止的距離t1，是大致等於環片1之側板103與內部板106之相對向面間的距離，第1突起部22d、23d與第2突起部22e、23e之相對向的垂直面S2、S3間的距離t3，是環片1之側板103(或側板102)於管長方向之厚度t2的大致2倍。The distance t1 from the interface S1 between the protruding portions 22b and 23b of the coupling pin 21 and the semi-tubular portions 22c and 23c to the vertical surface S2 of the first projections 22d and 23d is substantially equal to the side plate 103 and the inside of the ring piece 1. The distance between the opposing faces of the plate 106, the distance t3 between the first projections 22d and 23d and the opposing vertical faces S2 and S3 of the second projections 22e and 23e is the side plate 103 of the ring piece 1 (or the side plate 102). ) is approximately twice the thickness t2 in the direction of the tube length.
分離銷24之前端部24b、中央部24c、後端部24d的外徑p1、p3、p2為p3>p2>p1的關係。The outer diameters p1, p3, and p2 of the front end portion 24b, the central portion 24c, and the rear end portion 24d of the separation pin 24 have a relationship of p3 > p2 > p1.
在連結銷半體22、23已疊合後的狀態下，分離銷24的中央部24c，係具有可被收納於連結銷21之中空部21c的大小，而無法***於中空部21b的大小，分離銷21的前端部24b，亦具有無法***於連結銷21之中空部21a的大小。但是，當將壓力施加壓入到分離銷24時，分離銷24的中央部24c便會被壓入到連結銷的中空部21b，又，分離銷24的前端部24b亦被設成可以被壓入到連結銷的中空部21a之大小。又，分離銷24的中央部24c被壓入於連結銷的中空部21b，而分離銷24的前端部24b已被壓入到連結銷的中空部21a時，連結銷21會被壓擴開，使連結銷的結合部22a、23a被拉斷而分離成連結銷半體22、23，使分離後的連結銷半體22、23藉由分離銷24而朝向環片1的側板103與內部板106的各插通孔103a、106a壓接。In a state in which the coupling pin halves 22 and 23 are overlapped, the center portion 24c of the separation pin 24 has a size that can be accommodated in the hollow portion 21c of the coupling pin 21, and cannot be inserted into the hollow portion 21b. The distal end portion 24b of the separation pin 21 also has a size that cannot be inserted into the hollow portion 21a of the coupling pin 21. However, when the pressure application is pressed into the separation pin 24, the central portion 24c of the separation pin 24 is pressed into the hollow portion 21b of the coupling pin, and the front end portion 24b of the separation pin 24 is also set to be pressed. The size of the hollow portion 21a that enters the joint pin. Further, the center portion 24c of the separation pin 24 is press-fitted into the hollow portion 21b of the coupling pin, and when the front end portion 24b of the separation pin 24 is pressed into the hollow portion 21a of the coupling pin, the coupling pin 21 is pressed and expanded. The joint portions 22a and 23a of the joint pin are separated and separated into the joint pin halves 22 and 23, and the separated joint pin halves 22 and 23 are oriented toward the side plate 103 and the inner panel of the ring piece 1 by the separation pin 24. Each of the insertion holes 103a and 106a of the 106 is crimped.
其次，說明使用如此所構成的連結具來將環片連結於管長方向的方法。Next, a method of joining the ring piece to the pipe length direction using the coupling member configured as described above will be described.
連結銷21，如第4圖(a)、(c)所示，在連結銷半體22、23被疊合，分離銷24被收納於連結銷21內的狀態下，如第7圖(a)所示，將要***於一個環片1之側板103的插通孔103a。As shown in Fig. 4 (a) and (c), the connecting pin 21 is in a state in which the connecting pin halves 22 and 23 are overlapped and the separating pin 24 is housed in the connecting pin 21, as shown in Fig. 7 (a). ), the insertion hole 103a to be inserted into the side plate 103 of one ring piece 1 is shown.
連結銷21的半管狀部22c、23c，由於可以通過環片1之側板103的插通孔103a，又，突出部22b、23b可以通過內部板106的插通孔106a，故連結銷，如第8圖(a)所示，為帶有預定之間隙而被***於各插通孔103a、106a。又，由於連結銷21的第1突起部22d、23d的***側(左側)為傾斜，故只要強壓分離銷，如第8圖(b)所示，第1突起部22d、23d藉由連結銷的彈性而通過插通孔103a，此時，由於從突出部22b、23b與半管狀部22c、23c的交界面S1起到第1突起部22d、23d之垂直面S2為止的距離(t1)，相等於側板103與內部板106之相對向面間的距離，所以交界面S1會抵接於內部板106的內側面，垂直面S2會抵接於側板103的內側面。Since the semi-tubular portions 22c and 23c of the joint pin 21 can pass through the insertion holes 103a of the side plates 103 of the ring piece 1, and the protruding portions 22b and 23b can pass through the insertion holes 106a of the inner plate 106, the joint pins, such as 8(a) is inserted into each of the insertion holes 103a and 106a with a predetermined gap. Further, since the insertion side (left side) of the first projections 22d and 23d of the coupling pin 21 is inclined, as long as the separation pin is strongly pressed, as shown in Fig. 8(b), the first projections 22d and 23d are connected by the pins. The elasticity passes through the insertion hole 103a. At this time, the distance (t1) from the interface S1 between the protruding portions 22b and 23b and the semi-tubular portions 22c and 23c to the vertical surface S2 of the first projections 22d and 23d is The phase is equal to the distance between the opposing faces of the side plate 103 and the inner plate 106. Therefore, the interface S1 abuts against the inner side surface of the inner plate 106, and the vertical surface S2 abuts against the inner side surface of the side plate 103.
此狀態下，如第8圖(c)、(d)所示，當將分離銷24的後端部24d壓入，使分離銷24的中央部24c壓入於連結銷的中空部21b，使分離銷的前端部24b壓入連結銷的中空部21a時，連結銷，其連結部22a、23a便被拉斷而使連結銷半體22、23分離。並且，已分離的各連結銷半體22、23藉由分離銷24被壓擴開而使連結銷的突出部22b、23b壓接於內部板106的插通孔106a，並且其半管狀部22c、23c壓接於側板103的插通孔103a。藉此，使連結銷固定於環片1。此時，由於半管狀部22c、23c的交界面S1是被壓接於內部板106的內側面，又第1突起部22d、23d的垂直面S2是被壓接於側板103的內側面，所以使連結銷對環片的固定可變得確實牢靠，並且可以防止連結銷從環片脫落。此狀態於第7圖(b)亦圖示出。In this state, as shown in Fig. 8 (c) and (d), when the rear end portion 24d of the separation pin 24 is press-fitted, the central portion 24c of the separation pin 24 is press-fitted into the hollow portion 21b of the coupling pin. When the distal end portion 24b of the separating pin is press-fitted into the hollow portion 21a of the connecting pin, the connecting pin is opened, and the connecting portions 22a and 23a are pulled apart to separate the connecting pin halves 22 and 23. Further, the separated coupling pin halves 22, 23 are press-expanded by the separating pin 24 so that the protruding portions 22b, 23b of the coupling pin are crimped to the insertion holes 106a of the inner panel 106, and the semi-tubular portion 22c thereof And 23c is crimped to the insertion hole 103a of the side plate 103. Thereby, the joint pin is fixed to the ring piece 1. At this time, since the interface S1 of the semi-tubular portions 22c and 23c is pressed against the inner side surface of the inner panel 106, and the vertical surface S2 of the first projections 22d and 23d is pressed against the inner side surface of the side plate 103, The fixing of the connecting pin to the ring piece can be made secure, and the connecting pin can be prevented from falling off the ring piece. This state is also illustrated in Figure 7(b).
接著，如第8圖(e)、(f)所示，將與已分離成連結銷半體22、23之連結銷***側為相反側的另一端，***於另一環片1’之側板102的插通孔102a。由於連結銷半體22、23為分離，可朝內側撓彎，所以可容易***。側板102是穿越過第2突起部22e、23e的傾斜面，連結銷21與環片1’的側板102是鉚固性地嵌合固定。此時，由於第1突起部與第2突起部之相互對向之垂直面S2、S3間的距離，為側板103(102)之板厚的大致2倍，所以環片1’的側板102，為壓接於環片1的側板103與第2突起部22e、23e的垂直面S3間的狀態下被固定。又，藉由第2突起部22e、23e防止環片1’從連結銷脫落。如此地實施，由於環片1’被固定於連結銷，所以可以將環片1與1’堅固地連結於管長方向。Next, as shown in Fig. 8 (e) and (f), the other end opposite to the side on which the coupling pin of the coupling pin halves 22 and 23 is separated is inserted into the side plate 102 of the other ring piece 1'. The insertion hole 102a. Since the joint pin halves 22 and 23 are separated, they can be bent toward the inside, so that they can be easily inserted. The side plate 102 is an inclined surface that has passed through the second projections 22e and 23e, and the joint pin 21 and the side plate 102 of the ring piece 1' are caulked and fixed. At this time, since the distance between the vertical faces S2 and S3 of the first projection and the second projection facing each other is substantially twice the thickness of the side plate 103 (102), the side plate 102 of the ring piece 1' is It is fixed in a state of being pressed between the side plate 103 of the ring piece 1 and the vertical surface S3 of the second protrusions 22e and 23e. Further, the second projections 22e and 23e prevent the loop piece 1' from coming off the coupling pin. As described above, since the ring piece 1' is fixed to the joint pin, the ring pieces 1 and 1' can be firmly coupled to the pipe length direction.
第9圖(a)、(b)，是顯示從上面俯視觀察由連結具20所連結之環片1、1’的連結狀態。Fig. 9 (a) and (b) show the connected state of the ring pieces 1, 1' connected by the connecting device 20 in plan view from above.
又，連結銷，其斷面不為圓管狀，而製成正六角形等多角形狀亦可。此時，環片的側板與內部板之插通孔的形狀也要事先製成相對應的形狀。又，連結銷的第1與第2突起部，可及於連結銷之整個周方向地形成，或是於周方向斷續性地形成亦可。Further, the connecting pin may have a polygonal cross section and may have a polygonal shape such as a regular hexagon. At this time, the shape of the insertion hole of the side plate and the inner plate of the ring piece is also formed into a corresponding shape in advance. Further, the first and second projections of the coupling pin may be formed over the entire circumferential direction of the coupling pin or may be formed discontinuously in the circumferential direction.
環片之供連結具用的插通孔，如第1圖所示，是沿著側板與內部板的周方向形成複數個，所以在複數個插通孔之中使連結具20***於預定數量的插通孔，藉由該連結具來進行環片於管長方向的連結。但是，由連結具20進行環片之連結，由於是夾介短的連結具來進行，所以連結強度較弱。因此，如日本特開2005-299711號公報所揭示，將跨越該環片於管長方向之寬幅而延伸的連結棒***於環片的插通孔，藉由使其一端與被固定於另一環片之連結棒的另一端結合，將連結棒固定於該環片，並且，夾介連結棒將該環片與另一環片連結於管長方向。此狀態顯示於第10圖。As shown in FIG. 1, the insertion hole for the connection piece of the ring piece is formed in plural along the circumferential direction of the side plate and the inner plate, so that the coupling piece 20 is inserted into the predetermined number among the plurality of insertion holes. The insertion hole is used to connect the ring piece in the tube length direction by the connecting piece. However, since the connection of the loop piece by the joint 20 is performed by the joint with a short clip, the joint strength is weak. Therefore, as disclosed in Japanese Laid-Open Patent Publication No. 2005-299711, a connecting rod extending across a wide width of the ring piece in the length direction of the tube is inserted into the insertion hole of the ring piece, and one end thereof is fixed to the other ring. The other end of the connecting rod of the sheet is coupled to fix the connecting rod to the ring piece, and the interposing connecting rod connects the ring piece and the other ring piece to the tube length direction. This status is shown in Figure 10.
於第10圖，環片1、1’、1”，在一部分以夾介上述之連結具20所連結。又，金屬之固定用螺帽32***通於環片1的側板103、以及環片1’的側板102，並藉由將金屬螺栓33夾介環片1的內部板106螺鎖入固定用螺帽32，使固定用螺帽32被固定於環片1。In Fig. 10, the ring pieces 1, 1', 1" are partially joined by the above-mentioned connecting device 20. Further, the metal fixing nut 32 is inserted into the side plate 103 of the ring piece 1, and the ring. The side plate 102 of the sheet 1' is screwed into the fixing nut 32 by the metal bolt 33 sandwiching the inner plate 106 of the ring piece 1, so that the fixing nut 32 is fixed to the ring piece 1.
跨越環片之兩側板102、103而延伸的金屬連結棒31，係於軸部31b的一端具有螺紋部31a，另一端為於內部具有螺紋31d的螺帽部31c。The metal connecting rod 31 extending across the side plates 102, 103 of the ring piece has a threaded portion 31a at one end of the shaft portion 31b, and a nut portion 31c having a thread 31d inside.
使連結棒31通過環片1’的側板及內部板的各插通孔，藉由旋轉螺帽部31c之從環片1’的側板103所露出的部分，將連結棒31的螺紋部31a螺鎖入固定用螺帽32。當將連結棒31螺鎖到使螺帽部31之***側的端部壓接於內部板106，連結棒31固定於環片1’之同時，藉由連結棒31使環片1’在被鎖緊於環片1的狀態下而連結。，此時，位於環片1’之連結棒31的螺帽部31c，由於發揮被固定於環片1之固定用螺帽32之功能，因此同樣地，使用另一連結棒31，可以將環片1”連結於環片1’，同樣地重覆施作，夾介連結棒而可以將複數個環片依序連結於管長方向。The connecting rod 31 is passed through the insertion holes of the side plate and the inner plate of the ring piece 1', and the threaded portion 31a of the connecting rod 31 is screwed by the portion of the rotating nut portion 31c exposed from the side plate 103 of the ring piece 1'. The fixing nut 32 is locked. When the connecting rod 31 is screwed to the end portion on the insertion side of the nut portion 31, the connecting rod 31 is fixed to the inner sheet 106, and the connecting rod 31 is fixed to the ring piece 1', and the ring piece 1' is made by the connecting rod 31. It is connected in a state of being locked to the ring piece 1. In this case, since the nut portion 31c of the connecting rod 31 located in the ring piece 1' functions as a fixing nut 32 that is fixed to the ring piece 1, the other connecting rod 31 can be used in the same manner. The sheet 1" is connected to the ring piece 1', and is repeatedly applied in the same manner, and the plurality of ring pieces can be sequentially connected to the tube length direction by interposing the connecting rod.
於以下，說明使用環片來更生既設管的方法。In the following, a method of using a ring piece to regenerate a pipe is described.
首先，如第11圖所示，將環片1經由人孔井40搬入於既設管41內，然後將環片1，以如第2圖所示方式，依序連結於周方向來組裝成管單元10。First, as shown in Fig. 11, the ring piece 1 is carried into the existing pipe 41 through the manhole well 40, and then the ring piece 1 is sequentially connected to the circumferential direction as shown in Fig. 2 to be assembled into a pipe. Unit 10.
接著，同樣地組裝管單元10，再將已組裝好的管單元10連結於管長方向。該管單元10的連結，是藉由使用上述的連結具20及/或是連結棒31連結管單元10的各環片1來進行。Next, the tube unit 10 is assembled in the same manner, and the assembled tube unit 10 is connected to the tube length direction. The connection of the tube unit 10 is performed by connecting the respective ring pieces 1 of the tube unit 10 using the above-described coupling 20 and/or the connecting rod 31.
如以上所述，藉由在既設管41內將管單元10依序連結於管長方向，而能夠將更生管42鋪設於既設管41內。該狀態亦於第12圖中被圖示出。在第12圖中，與第3圖相同樣地僅圖示出主要要部，對於連結具、連結棒等管長方向的連結手段或是周方向的連結手段，為了避免煩雜乃省略其圖示。As described above, the tube unit 10 can be sequentially connected to the tube length direction in the existing tube 41, whereby the tube 42 can be laid in the existing tube 41. This state is also illustrated in Figure 12. In the same manner as in the third embodiment, only the main parts are illustrated in the same manner as in the third embodiment, and the connection means in the pipe length direction such as the connecting device and the connecting rod or the connecting means in the circumferential direction are omitted in order to avoid nuisance.
於更生管42的外周與既設管41的內壁面之間，由於會產生縫隙43，所以在此充填漿料材(grout)等之填充材，使更生管與既設管一體化。又，在本實施例中，管單元10其各環片的端板，雖然是與另外一管單元之環片的端板以偏位方式組裝，不過各個端板以對齊之方式來組裝亦可。第9圖，是將環片的各端板以對齊的方式組裝時的例示。Since the gap 43 is formed between the outer circumference of the tube 42 and the inner wall surface of the existing tube 41, a filler such as a grout is filled here, and the tube is integrated with the existing tube. Moreover, in the embodiment, the end plates of the ring members of the tube unit 10 are assembled in an offset manner with the end plates of the ring pieces of the other tube unit, but the end plates may be assembled in an aligned manner. . Fig. 9 is an illustration of the case where the end plates of the ring piece are assembled in an aligned manner.
