長いPC鋼材は不必要であり、不経済さを免かれない。That is, the PC steel plate inserted into the lower side plate from the lower part m1 of the lower part 1', and the part inserted from the upper surface part of the upper half member
The PC steel material inserted into the L part side plate is connected by a coupler (long nut for connecting steel materials) at the joint between the lower side plate and the second part side plate, and these PC steel members are tensioned. I try to give prestress. However, if the moment I and shearing force of the lower connecting portion are calculated using this prestress, such a long PC steel material is unnecessary and uneconomical.

手間がかかるという問題がある。It has also been considered that a prestressed steel material is buried in the side plate of the toe section in advance, and that this PC steel material and the prestressed steel material inserted into the upper side plate are connected by a coupler. 2. If the axes of the lower PCwI material are not completely aligned, it will not be possible to connect them with a coupler, which will take time and effort during construction. There is.

の横ずれを防にするための鋼管25が装着しである。As shown in FIGS. 2 and 3, the underdrain block 1 includes a lower half member 3 and a block assembled on the lower half member 3.
- It is equipped with the half member 4 and the connecting means 5 for connecting these M m members 3.4. The lower half member 3 has a length of 1. .. It is approximately U-shaped and is formed by consecutively arranging different lower side plates 7.8 of 1 unit. Also,
The upper half member 4 is approximately U-shaped, with J-part side plates 11.12 having different lengths in the downward direction (1-13.14) arranged on the left and right edges of the top plate 9; Department side version 11.12
is placed on the lower side plate 3 so as to butt against the lower side plate 7.8. Note that the sum of the lengths of the left lower side plate 7 and the upper side plate 11 (1, +15) is the sum of the lengths of the right lower side plate 8 and the L side plate 12 (12+1.). They are set to the same value, and the top plate 9 is held parallel to the bottom plate 6. Further, the connecting means 5 includes the lower side plate 7.8.
and a concave portion 13.14 formed at an intermediate position of the upper side plate 11.12, and both concave portions 13.1 bored inside the lower side plate 7.8 and the upper side plate 11.12.
4, a wire rod such as a PC steel material 16 inserted into the wire rod insertion hole 15 with both ends positioned in the double concave portions 13.14, and each of the concave portions of the PC steel material 16. 13. Nuts 19.20 screwed onto the insertion ends 16a and 16a, respectively, and the side plates 11 on the above.
.. 12, and the PC is installed at the time of the Nara I.20 inspection.
A passage 23 is provided for the purpose of inserting a pull rod 2z for applying tension to the steel material 16. Specifically, each of the recessed portions 13.14 corresponds to each of the lower side plates 7.
8 and the inner surface of each of the side plates 11 and 12 is recessed. In addition, screws are carved into the insertion ends 16a and 16b of the PC copper PC steel material 16 described in +ii+.
An anchor plate 24 is interposed between the recessed portion 13.14 and the recessed portion 13.14. Further, on the outer periphery of the pull lock F' 22 at the joint between the lower side plate 7.8 and the upper side plate 11.12, the side plates 7, 8.11.12
A steel pipe 25 is installed to prevent sideways slippage.

、きわめて経済的である。また。When installing the PC steel material 16, first insert a nut 1 into the lower insertion end 16a of the PCfi material 16.
9 and screw it onto the upper insertion end 16b (
'Temporarily fasten 20. Thereafter, the inner end of the pull rod 22 inserted into the passage 23 is connected to the insertion end 16 of the PC steel material 16 via the coupler 26. b, and the outer end of the pull rod 22 is connected to the hydraulic jack 2.
7 to give tension to the PC steel material 16. Then, the nut 20 is fully tightened, and then the coupler 1iij is removed from the PC#l material 6 and the pull rod 22 nQ, and the pull rod 22 is removed from the passage 23. Since a plurality of the PC steel materials 16 are provided at predetermined intervals, each of the PC steel materials 16 is stretched by performing the above operations in sequence. In addition, a plurality of horizontal tightening PC steel members 28 and 29 are stretched over the bottom plate 6 and the fourth plate 9. A plurality of underdrain blocks 1 thus constructed are connected to the alternating current V with the front and back reversed, and these are tightened and fixed by vertically tightening PC steel members 31. The tensioning mode of this vertically tightened PC #l material 31 is similar to that of the PC steel material j6, and 32 and 33 are recessed portions. If it is a culvert pro-nk 1 with such a configuration, the lower side version is 7.8
The lower half member 3 and the upper half member 4 can be firmly connected by a short PC steel material 16 stretched between the recessed part 13 provided in the upper side plate 11.12 and the recessed part 14 provided in the upper side plate 11.12. This reduces the amount of steel compared to the conventional method in which the PC steel material inserted from the lower end of the lower half member and the PC steel material inserted from the L end of the upper half member are connected with a campler and both parts are fixed with wheat cotton. It has the advantage of being able to be significantly reduced, making it extremely economical. Also.
このようなものであれば、前記PCM材16を張設する
際に、固定された鋼材等との間で芯合わせを行なう必要
がないので、組立作業が容易になるという効果もある。If this is the case, there is no need to align the PCM material 16 with a fixed steel material or the like when the PCM material 16 is stretched, thereby facilitating the assembly work.

という効果が得られる。Furthermore, in this embodiment, the lower side plate 7.8 and the upper side plate 1
1.12 Since the steel pipe 25 is interposed at each joint, it is possible to effectively prevent the lower half member 3 and the upper half member 4 from shifting laterally. Also, since the lengths of the left and right dome side plates 7.8 and the lengths of the left and right upper side plates 11.12 are different, the main culvert block l can be swapped front and back as described above. As long as they are connected alternately, the lower side plates 7
.. 8, the upper side plate 11, and the workpiece 2 have different levels at the front and back, and this level can prevent vertical displacement between the lower side plate 7.8 and the upper side plate 11.12. . Therefore, in the past, four pieces of vertically fastening PC steel were required for tightening and fixing the lower half members together, and four vertically fastening PC steels were needed for tightening and fixing the upper half members together, but the present proposal In this case, it is possible to obtain the effect that only two trees are required for each.
なお、本発明に係る暗渠ブロックは、前記のような縦締
