Description
Изобретение относитс к ребристым блокам дл сборных, преимущественно , железобетонных обделок тоннелей. Известные такого рода ребристые блоки, собранные в кольцо обделки, при раскрытии швов на стыках передают нормальные к торцам блоков усили через смежные ребра. При такой передаче усилий возлшжно перенапр жение материала и разрушение ребер.The invention relates to ribbed blocks for prefabricated, predominantly, reinforced concrete lining of tunnels. Known such kind of ribbed blocks, gathered in a ring lining, when opening the seams at the joints, the forces normal to the ends of the blocks are transmitted through adjacent ribs. With such a transfer of force, overvoltage of the material and destruction of the ribs are possible.
В описываемом ребристом блоке этот недостаток устранен тем, что ребра расположены лишь на удлиненных сторонах блока и им придана переменна но длине высота, с уменьшением ее К местам соединени блоков в кольце, а дл компенсации потери площади поперечного сечени блока на участке с уменьшенной высотой ребер и упрочнени его, плита блока на част х длины, примыкающей к соединени м, выполнена утолшенной.In the ribbed block described, this disadvantage is eliminated by the fact that the ribs are located only on the elongated sides of the block and are given a variable height, with a decrease in its connecting points of the blocks in the ring, and to compensate for the loss of the cross-sectional area of the block its hardening, the block plate on parts of the length adjacent to the joints, is made thickened.
На фиг. 1 и 2 показаны две различные проекции ребристых блоков, соединенных в обделку тоннел , а на фиг. 3-деталь соединени блоков в кольце.FIG. 1 and 2 show two different projections of the ribbed blocks connected to the lining of the tunnel, and FIG. 3-detail connection blocks in the ring.
Блок выполнен в виде пр моугольной плиты / криволинейного очертани .The block is made in the form of a rectangular plate / curvilinear outline.
По обоим удлиненным сторонам блока расположены два ребра 2. Эти ребра имеют переменную высоту, котора уменьшаетс в направлении к торцам (укороченных сторон) 3 блока. Уменьшение площади поперечного сечени блока в месте снижени высоты ребер компенсируют утолщени ми 4 плиты блока. Эти утолщени способствуют упрочнению блока и размещены на части его длины, примыкающей непосредCTBeiHio к месту соединени смежных блоков в кольце обделки. Дл скреплени блоков в кольце обделки применены скобы 5, забиваемые в дерев нные пробки 6 двух смежных блоков, вделанные в тело блоковOn each of the elongated sides of the block are two ribs 2. These ribs have a variable height, which decreases towards the ends (shortened sides) of 3 blocks. The reduction in the cross-sectional area of the block at the site of lowering the height of the ribs is compensated by thickening 4 of the slab of the block. These thickenings contribute to the reinforcement of the block and are placed on a part of its length, adjacent the CTBiHio directly to the junction of adjacent blocks in the lining ring. For fastening the blocks in the ring of lining, brackets 5 are used, driven into wooden plugs 6 of two adjacent blocks, embedded into the body of blocks.
с применением металлических трубок. Дл креплеии колец обделки тоннел между собой, в ребрах блоков сделаны отверсти 7. Дл обеспечени водонепроницаемости обделки предусмотрены расчеканочные канавки 8.using metal tubes. Holes 7 are made for fastening the tunnel lining rings between themselves, and blocking grooves 8 are provided to ensure the watertightness of the lining.
Предмет изобретени Subject invention
Ребристый блок дл сборной, нреимущественно, железобетонной обделки тоннел , отличающийс тем, что, с целью предотвращени возможности передачи нормальной силы в кольце обделки через ребра, последние расположены лишь на удлиненных сторонах блока и им придана неременна высота, а дл компенсации потери площади поперечного сечени на участке с уменьшенной высотой ребер и упрочнени блока его плита на части длины, примыкающей к соединению, выполнена утолщенной.The ribbed block for the team, predominantly a reinforced concrete lining of the tunnel, is characterized in that, in order to prevent the transfer of normal force in the lining ring through the ribs, the latter are located only on the elongated sides of the block and given a non-interchangeable height, The section with a reduced height of the ribs and the hardening of the block; its plate is made thicker on a part of the length adjacent to the joint.
