Description
женной головки; на фиг. 5 ч- то же, но с уттолщением в виде опрессованной гильзы.female head; in fig. 5 is the same, but with a thickening in the form of a molded sleeve.
Стыковое соединение включ ает плитыоголовники 1 на торцах стыкуёмйх элементов , концы продольной арматуры 2, фиксируемые в конусных отверсти х нлит дуговой сваркой. :The butt joint includes plate-heads 1 at the ends of the junction elements, the ends of the longitudinal reinforcement 2, fixed in the conical holes of the nlite by arc welding. :
Сварные швы 3 выполн ют после установки косвенной арматуры 4.The welds 3 are made after the installation of indirect reinforcement 4.
Наличие утолщений в виде высаженных головок 5 или опрессованных гильз 6, опертых на внутреннюю поверхность плиты, позвол ет сократить объем сварочных работ , производить приварку стержней кплитб йёрасчетным однослойным Швом, что, в свЪю очередь, способствует повбгшейию несущей способности и прочности стыка, предотвраща перегрев арматуры и ее разупрочнение . -- . , :, . .... .- . ..The presence of bulges in the form of upset heads 5 or crimped sleeves 6, supported on the inner surface of the plate, reduces the amount of welding, welds the rods to the flatbed single-layer weld, which, in turn, contributes to the bearing capacity and strength of the joint, preventing overheating of the reinforcement and its softening. -. ,:,, .... .-. ..
ВэтЬм отнощении наибольший эффектдостигаетс при использовании высокопрочной термоупрочненной арматурьг, наттр имер классов Ат-V и Ат-VI. - - This ratio has the greatest effect when using high-strength heat-strengthened reinforcement, natr imer of the At-V and At-VI classes. - -
Монтаж колонны осуществл ют в следующей последовательности.The assembly of the column was carried out in the following sequence.
Производ т установку вышеЛ ежащего лемента на центрирующую прокладку 7, приваренную к внешней поверхности плиты или на тонкий слой твердеющего раствора. После рихтовки осуществл ют дуговую сварку плит прот женным щвом 8 по их периметру .The installation of the above-mentioned horizontal element is carried out on the centering gasket 7, welded to the external surface of the plate or on a thin layer of hardening solution. After leveling, arc welding of the plates with the long groove 8 along their perimeter is carried out.
В отдельных случа х утолщени на концах стержней могут не выполн тьс .In some cases, the bulges at the ends of the rods may not be performed.
Но в этом случае необходимо предотвращать перегрев арматуры в месте примыкаШй к внутренней поверхности плит до 500° С наложением каждого последующего шв;а после охлаждени предыдущего до 100° СПри нзготовле.нии сборных элементов колонны плиты-оголовники используютс как торцы форм.But in this case, it is necessary to prevent overheating of the reinforcement in the area adjacent to the inner surface of the plates up to 500 ° C by overlaying each subsequent weld, and after cooling the previous one to 100 ° Prepared prefabricated elements of the column of end plates are used as the ends of the molds.
