Definitions

  • the present invention relates to joint sealing members for use in effecting water stopping processing at junctions of members used for civil engineering works or the like.
  • plural unit segments l are used as work materials in construc­ting a shield tunnel excavated underground. These unit segments l are closely joined in the direction a along the peripheral wall and in the longitudinal direction b of the gallery.
  • each of segments l there are provided front and rear flanges 2 and 3 extending in the circumferential direction a around the peripheral walls, and upper and lower flanges 4 and 5 extending in the longitudinal direction b .
  • front and rear flanges 2 and 3 extending in the circumferential direction a around the peripheral walls, and upper and lower flanges 4 and 5 extending in the longitudinal direction b .
  • a band-like joint sealing member 8 is secured by bonding onto one side of the flange surfaces facing gaps 7 between adjacent flange surfaces.
  • a well-known water expansible material such as a material obtained by mixing, synthesizing and vulcan­izing high hygroscopic resin and synthetic rubber is used.
  • the sealing member 8 is formed into a single layer using the above-mentioned material. The sealing member 8 expands due to infiltration of water W into the joint so as to watertightly seal the gap 7.
  • Figure 2B depicts another prior art arrangement.
  • a belt-like fitting groove for example, a groove 4a in the flange 4
  • a joint member 8 is fixed in each of the fitting grooves.
  • the surface of the joint member 8 projects from the outer surface of each of the flanges 2 and 4.
  • the flanges 2 and 3 of the respective segments lA and lC are fixedly clamped together by three connecting bolts 6, and the flanges 4 and 5 of the respective segments lA and lB are fixedly clamped by two connecting bolts 6 such that the joint member 8 is compressed by a thick­ness t and the outer surface of the joint member 8 is urged against the outer surface of the flange 5 by elas­tic force, thereby effecting water stopping processing at the joint junction.
  • the joint member 8 must be made thicker so as to sufficiently include the thickness t therein so that the joint member 8 largely projects from the flange 4. Accordingly, not only is a large amount of effort required for screwing on the nuts 6a, but also the projecting edge of the joint member 8 is apt to be caught thereby, causing the joint member 8 to slip out of the fitting groove 4a.
  • the present invention has been attained to solve the difficulties mentioned above.
  • a specific object of the present invention is to provide a joint sealing member mainly constituted by a water expansible material in which effective expansion in the direction of thickness can be obtained, stable bonding of the bottom surface of the sealing member can be ob­tained, and effective initial water stopping processing can be accomplished without increasing the thickness of the sealing member.
  • a band-like joint seal­ing member is fea­tured in that the band-like joint sealing member can be formed with longitudinally extending rib-like ridge portions formed integrally on one surface of a band-like base plate made of a water expansible material.
  • Figure 4 shows a section of a joint junction portion where a wide joint member l7 (one embodiment) and a similarly shaped narrow joint member l8 (another embodi­ment) are fixed in two rows between a flange l5 of a segment lD and a flange l6 of a segment lE.
  • the joint members l7 and l8 are respectively adhered to fitting grooves l6a and l6b of the flange l6.
  • the joint member l7 is made of a material obtained by mixing, synthesizing and vulcanizing a water expansible material such as high-grade water resin and synthetic rubber.
  • a water expansible material such as high-grade water resin and synthetic rubber.
  • synthetic rubber l,3 diene group rubber containing a crystal domain (or glassy domain) of 5 to l0% at a normal temperature is used.
  • the joint member l7 has two rows of rib-like ridge por­tions l7b each having a substantially semi-circular cross-section extending upwardly from one surface of a strip-like elongated base plate portion l7a.
  • the thickness of the base plate l7a of the joint member l7 is substantially the same as the depth of the fitting groove l6a so that the surface of the base plate l7a is substantially even with the surface of the flange l6.
  • Each of the ridge portions l7b is shaped to have a crest which is high enough to sufficiently project to fill the width t so that, in the state in which the nut 6a is screwed onto the connecting bolt 6 as shown in Figures 4 and 5, the crest portion of each ridge portion l7b is compressed by the thickness t and caused to closely contact with the surface of the flange l5 by its own elastic force.
  • joint member l7 With the joint member l7 according to this embodiment (the same applies to the joint member l8) arranged in the manner as described above, not only is there an advantage of saving material because of the smaller thickness of the base plate l7a, but also, since the base plate l7a becomes substantially even with the face of the flange l6, there is no risk that the joint member will be pulled out of the fitting groove l6a in the joint connecting operation. Moreover, since the crest portion of the ridge portion l7b is compressed when the fixing nut 6a is screwed on, the tightening operation can be easily performed.
  • the joint member l7 of this embodiment provides suffilycient watertightness due to close contact by the ridge portions l7b even at the initial stage, and after ab­sorbing water, as shown in Figure 7, the entire joint member l7 conforms to the flange l5 due to the force of expansion so that watertightness is always maintained.
  • the joint member according to the present invention can be widely used with the same effects in water stopping processing in joints of secondary concrete products such as culvert boxes, manholes, or the like, in joints of secondary steel products, colgate pipes, or the like.
  • the shape of the cross-section of the joint member is properly established in accordance with the condi­tions at hand. Possible shapes for the joint member are shown in Figure 8, chosen taking the following design factors into consideration.
  • the shape of the base plate a rectangle, trapezoid, oblique trapezoid, or the like, is preferable.
  • the thickness is increased, the watertightness is improved, while the workability for installation is lowered so as to cause, for example, a reduction in the strength of reinforcement.
  • the base plate is made too thin, the opposite result is caused.
  • the member is superior in compressibility and retention, but inferior in watertightness.
  • the opposite result is caused in the case of three ridge portions.
  • the width of the ridge portion is not specifically limited, it is preferable to select it to be l0-40% of the width of the base plate of the joint member. It is preferable to select the sectional area of the ridge portion to be l-200% of the sectional area of the base plate (5-l00% is more preferable). If the ridge portion is too small, it is inferior in compressibility as well as in reten­tion, and if it is too large, on the contrary, the watertightness is lowered.
  • a joint member for civil engineering works according to the present invention is formed such that longitudinally extending rib-like ridge portions are formed integrally on one surface of a belt-like base plate made of a water expansible material so that it is possible not only to reduce the cost of the joint member due to the reduction in thickness of the joint member, but also to improve its ease of installation.
  • a sealing member 22 according to a further embodiment, as shown in Figure 9, is constituted by two (upper and lower) layers, one being an expansible portion 23 posi­tioned in the center and the other being a non-expansible portion 24 constituted by opposite side frames integral­ly formed through a transversely extending bottom plate portion 24a (the member 22 being constituted by three layers in the transverse direction).
  • the amount of expensive water expansible material is reduced so that the production costs of the sealing member can be re­duced.
