  • a number of PC unit half plates 3 are prefabricated at a factory.
  • Each of these unit half plates 3 is formed of highly strong concrete 1 and tensed by unbonded PC steel bars 2.
  • the unit half plate 3 may be formed on its outer face with peripheral (or longitudinal) ribs 4, which extend all over the length in a curving direction, and on its inner and outer faces with a number of planes 5a to form together with the pairing half plate 3 a generally arched multiplanar unit 5 which has an arched portion of a polygonal section in the curving or longitudinal direction.
  • each of the ribs 4 there is buried the unbonded PC steel bar 2 which is tensed by a post-­tension and fastened at its two ends by means of not­shown nuts.
  • the unit half plate 3 is further formed on its outer face with a plurality of transverse ribs 6 which extend all over the width in a transverse direc­tion perpendicular to the curving direction.
  • Each of these transverse ribs 6 is formed with a duct 7.
  • a desired number of the unit half plates 3 thus prefabricated are temporarily assembled to abut against one another in the curving longitudinal direction and in the transverse directions.
  • the unit half plates 3 in each pair are fastened at their upper ends or tops to each other in their curving longitudi­nal direction by means of a peripheral fastener 8 such as a combination of a bolt and a nut.
  • the unit half plates 3 of the desired number adjoining side by side are fixed in their transverse direction, i.e., in the longitudinal direction of the resultant arched PC shel­ter structure by threading a desired number of trans­versely fastening PC steel bars 9 into the individual ducts 7 and by fastening the steel bars 9.
  • these steel bars 9 to be suitably used may be either unbonded PC ones which are coated with asphalt or tar so that they may not be wetted with the concrete or post-­tension PC ones which use sheaths.
  • the unit half plate 3 may be made of fiber-reinforced high strong concrete.
  • the unit half plate 3 has its lower end (or leg) 10 is positioned on a support mounted on a foundation 11 and is hinged to the founda­tion 11 by means of anchor bolts.
  • the unit half plate 3 may be equipped at its abutting top with an elastic member and formed at its leg with a hinge structure by burying in the foundation 11 a concrete hinge preformed in the unit half plate 3.
  • a light-weight prefabricated PC shelter structure can be easily laid and erected in the field without substantially blockading the traffic.
  • This prefabricated PC shelter structure can be made firm because it is monolithically constructed of the nu­merous PC steel bars 2 and 9 in the curving longitudi­nal and transverse directions of the unit half plates 3. Since the ribs 4 and 6 are formed on the outer face, moreover, their PC steel bars 2 and 9 can be effective to provide a shelter structure which is firm against an external force. Since the unit 5 construc­ted of the paired unit half plates 3 has a multiplanar section, furthermore, it is possible to form concrete into a unit half plate 3 which has an arch half suited for the windings, undulations and grades of the road.
  • each pair of PC unit half plates 3A which are to be fastened to­gether by the transversely fastening PC steel bars 9 into the arched shelter structure, have not the multi­ planar section, as in the foregoing embodiment, but a generally continuously curving section.
  • Each unit half plate 3A is arranged with at least one aperture 12, in which there is fitted a transparent or semitransparent face plate 13 of a synthetic resin from the outer or inner face through a not-shown suitable member to pro­vide a natural lighting window.
  • the unit half plate 3A may also be formed on either its inner face or its inner and outer faces with ribs 4 and 6 to be arranged with the PC steel bars 2 and 9.
  • the generally arched unit may have their two ends or legs 10 fixed rigidly in the field to not-numbered posts which are also prefabricated at the factory.
  • FIG. 6 to 10 there is shown a process for prefabricating the unit half plates 3 and 3A of Figs. 1 to 5 in accordance with a third embodi­ment of the present invention.
  • An arching form 21 is constructed by assembling a top form frame 22, a bottom form frame 23 and side form frames 24 by not-shown fastening means.
  • the top form frame 22 is formed with two rows of, for example, peripheral rib forming por­tions 25, each of which in turn is formed with seven­teen placing ports 26 at an equal interval.
  • Reference numeral 27 denotes an erection structure for supporting the arching form 21 thus constructed.
  • the concrete is stored in the not-numbered tank of a concrete pump car 28.
  • the placing pipe 29 of the concrete pump car 28 is at first connected to the lowermost placing port 26 of one side of the arching form 21 to pump the concrete 30 via the placing pipe 29 into the arching form 21 up to the level of the lower­most placing port 26 by the action of the concrete pump. Then, the placing pipe 29 is disconnected from the lowermost placing port 26, and this placing port 26 is sealed with a not-shown cover. In this state, the concrete 30 is pumped into the arching form 21 up to the level of a next placing port 26. Thus, the con­crete 30 is placed into one side of the arching form 21 consecutively from lower to higher placing ports 26.
  • a top form plate 31 is posi­tioned at the peripheral center of the top placing port 26 so that the generally arched unit may be divided into two half plates 3 (of the first embodiment) or 3A (of the second embodiment).
  • the positioning of the top form plate 31 may be conducted either before or imme­ diately after the placing of the concrete 30 into the top form plate 31.
  • suita­ble inserts 32 for the ducts 7 of Figs. 2 and 4) and not-shown suitable inserts (for the peripheral fas­teners 8) are positioned in advance in the arching form 21. Meanwhile, the compaction of the concrete is car­ried out in time to the pumping action of the concrete pump car 28 by means of a high-frequency vibrator for vibrating the arching form 21.
  • the placing pipe 29 of the concrete pump car 28 is connec­ted to the several placing ports 26 one after another.
  • These placing ports 26 are formed in the top form frame 22 of the arching form 21 to pump and place the con­crete 30 sequentially from the bottom to the top of the arching form 21.
  • the space of the single placing action is re­stricted to a small one between the two adjacent placing ports 26 with a small head. This causes the air to move up sequentially upward, thus preventing it from being left confined in the concrete 30 and this concrete 30 itself from segregating.
  • the concrete pump car 28 Since, moreover, the concrete pump car 28 has its placing pipe 29 con­nected to the placing ports 26 one after another to sequentially pump the concrete 30 directly into the arching form 21 by its concrete pump, it can complete the concrete placing of the arching frame 21 within a short period of time. Thus, it is possible to con­struct an arched PC shelter structure which is voidless and excellent in strength and appearance.
  • the number and interval of the placing ports 26 may be appropriately selected.
  • the arching form 21 may be equipped with the placing ports 26 in its right and left sides and its top to place the concrete 30 sequentially from its bottom to the top.
  • the placing ports 26 are formed in the rib forming portions 25 of the top form frame 22 but may be formed between the portions 25.
  • the rib forming portions 25 of the top form frame may be omitted but may be formed in the bottom form frame 23.
  • the arched shelter structure can fit all the shapes including the arched multiplanar one.
  • the placing ports 26 may be used in the order from the right and left side ones to top one, and this order can be appropriately selected within the exemplified range.
  • the placing pipe 29 to be used with the concrete pump car 28 may employ suitable means of piping or boom type. Suitable means may be selected for connecting the placing pipe 29 to one of the placing ports 26.
  • These placing ports 26 need not be formed with the projecting mouths, as shown.
  • a number of unit half plates 41 are prefabricated of highly strong con­crete at a factory. These unit half plates 41 are paired and assembled together in the field to form generally arched units 42. These arched units 42 are then assembled in abutting states and fastened in the longitudinal direction of the resultant arched PC shel­ter structure by means of a plurality of fastening PC steel bars 43, e.g., unbonded PC steel bars which are arranged at a predetermined interval. Moreover, each of the unit half plates 41 has its outer face formed with peripheral or longitudinal ribs 44 and transverse ribs 44a and its inner face 45 curving generally conti­nuously.
  • the aforementioned PC steel bars 43 extend through the transverse ribs 44a.
  • these PC steel bars 43 are exemplified by the prestressed concrete> steel bars or the unbonded PC steel bars which are covered with asphalt or tar so that they may not be wetted with the concrete, but may be the post-tension PC steel bars using sheaths.
  • the unit half plate 41 may be prefabricated of highly strong concrete reinforced with fibers.
  • the paired unit half plates 41 have their lower ends or legs 46 hinged to foundations 47 by means of supports and anchor bolts and their abutting top ends 48 fas­tened by means of a peripheral fastener 49 such as a combination of a bolt and a nut.
  • a peripheral fastener 49 such as a combination of a bolt and a nut.
  • FIG. 41 is arranged therein with at least one aperture 50, in which there is fitted a transparent or semitransparent face plate 51 from the outer or inner face through suitable means such as a retaining or fitting member to form a natural lighting window 52.
  • Reference numeral 53 appearing in Fig. 13 denotes a side flange which is formed to extend from the inner face of the transversely abutting portion of each unit half plate 41 thereby to cover the abutting portion.
  • the unit half plates 41 are prefabricated in pairs of the highly strong concrete to form the generally arched units 42, which are then assembled in the longitudinal direction of the desired arched PC shelter structure to have their unit half plates 41 fastened by means of the transversely fastening PC steel bars 43.
  • the unit half plate 41 has its outer face formed with the crossing ribs 44 and 44a extending in the curving and transverse directions and its inner face curving gener­ally continuously.
  • the arched PC shelter structure to be con­structed can be made firm.
  • the inner face of the shelter structure is the continuously curving face 45 so that it can present a fine view, and the natural lighting windows 52 can present a well-lighted space in the arched shelter structure.
  • the ribs 44 and 44a are formed on the outer face to facilitate the mounting and fastening of the transverse PC steel bars 43.
  • the present invention should not be limited to the four embodiments thus far described but can be modified in various manners within the gist of itself.
