(54) СПОСОБ РЕКОНСТРУКЦИИ ЖЕЛЕЗОБЕТОННОГО БАЛОЧНОГО ПРОЛЕТНОГО СТРОЕНИЯ МОСТА(54) METHOD FOR RECONSTRUCTION OF REINFORCED CONCRETE PANEL BRIDGE
- Изобретение относитс к мостостро ению и может быть использовано при реконструкции с целью усилени и уширени проезжей части.железобетонных балочных пролетных строений, преимущественно автодорожных мостов.- The invention relates to a bridge construction and can be used in the reconstruction for the purpose of strengthening and broadening the carriageway. Reinforced concrete girder spans, mainly highway bridges.
Известен способ реконструкции железобетонного балочного -пролетного , строени моста, включающий укладку на балки монолитной железобетонной плиты с выступающими за габариты крайних балок консол ми Г1.There is a known method for the reconstruction of a reinforced concrete beam-span bridge, which includes laying monolithic reinforced concrete slabs on beams with G1 supports for the dimensions of the extreme beams.
Недостаток этого способа заключаетс в обеспечении лишь уиирени проезжей части практически без увеличени несущей способности реконструирог ванного пролетного строени .The disadvantage of this method is to ensure that only the roadside of the roadway is almost without increasing the carrying capacity of the reconstructed span.
Наиболее близким решением по технической сущности и достигаемому эффекту к изобретению вл етс способ реконструкции железобетонного балочного пролетного строени моста, включающий удаление части балок про летного строени , укладку по месту удсшенных балок элементов усилени , укладку монолитной плиты проезжей части с консол ми и объединение элементов усилени с соседними балкёими и плитой проезжей части, .причем элементы усилени выполнены в виде ребер , омоноличиваемых за одно целое с плитой проезжей части и размещен-; ных между балками С2.The closest solution to the technical essence and the achieved effect to the invention is a method of reconstructing a reinforced concrete beam span of the bridge, including removing part of the flying beam, laying locally of reinforcement elements, placing the monolithic plate of the carriageway with consoles and combining the reinforcement elements with the neighboring bulks and the slab of the carriageway, and the reinforcement elements are made in the form of ribs, which are uniformly integrated with the slab of the carriageway and placed; between C2 beams.
Недостаток данного способа реконструкции заключаетс в относительно малом повышении жесткости пролетного строени ввиду выполнени элементов усилени одинаковой с замен емыми балками высоты, а также в ог10 раниченной возможности уширени проезжей части и в относительно высокой трудоемкости работ по реконструкции .The disadvantage of this reconstruction method is the relatively small increase in the rigidity of the superstructure due to the reinforcement elements being the same as the height of the beams replaced, as well as the limited possibility of widening the carriageway and the relatively high labor intensity of the reconstruction works.
Цель изобретени - повышение жест15 кости пролётного строени , диапазона возможности уширени проезжей части и снижени трудоемкости работ по реконструкций . The purpose of the invention is to increase the rigidity of the span, the range of the possibility of widening the carriageway and reducing the laboriousness of the renovation works.
Указанна цель достигаетс тем, . This goal is achieved by
20 ;что согласно способу реконструкции железобетонного балочного пролетного строени моста, включающему удаление части балок пролетного строени , укладку по месту удаленных балок 20; according to the method of reconstruction of the reinforced concrete beam beam span of the bridge, including the removal of part of the span beams, laying at the place of distant beams
25 элементов усилени , укладку монолитной плиты проезжей части с консол ми и объединение элементов усилени с соседними балками и плитой проезжей части, удал ют только крайние балки, 25 reinforcement elements, laying of a monolithic slab of the carriageway with consoles and combining reinforcement elements with adjacent beams and a slab of the carriageway, only extreme beams are removed,
30 а дасле удалени их производ т пони30 to remove them, make ponies.
