Description
II
Изобретение относитс к области мостостроени и может быть использовано при монтаже конструкций деформационных швов автодорожных мостов больших пролетов.The invention relates to the field of bridge construction and can be used when mounting structures for expansion joints of highway bridges for large spans.
Известио приспособление дл монтажа конструкхщй швов, выполненное в виде стержн с винтовой нарезкой, соединенного с окаймл ющими элементами конструкции шва {1.Draw the device for mounting the structure of the seams, made in the form of a rod with a screw thread, connected to the bordering elements of the seam structure {1.
Недостатком зтого приспособлени вл етс невозможность регулировки положени злементов по высоте и предотвращешг их разворота из-за иаличи люфтов. Кроме того, указанное приспособление не может быть использовано при монтаже конструкций швов, рассчитанных на большие перемешени , из-за их повышенного собственного веса и незначительной жесткости самого устройства, в результате чего одно окаймление шва может разворачиватьс при монтаже относительно другого.The disadvantage of this device is the inability to adjust the position of the elements in height and prevent their reversal due to the limited play. In addition, the specified device cannot be used when installing structures of joints designed for large mixes, due to their increased own weight and low rigidity of the device itself, as a result of which one border of the seam can unfold during installation relative to the other.
Наиболее близким к описьшаемому изобретению по технической сущности и достигаемому результату вл етс опорна рама дл монтажа конструкций деформационных цшов включающа ригель и опорные стойки 2.The closest to the described invention to the technical essence and the achieved result is a support frame for mounting the structures of the expansion joint, including a transom, and support legs 2.
К ригелю рамы прикрепл ют с помощью болтов окаймлени , раздвинутые заранее на необходимое рассто ние в соответствии с температурой воздуха перед монтажом. Опорные стойки имеют возможность поднимать и опускать окаймлени на проектную высоту.The frames are fastened to the deadbolt with the help of bolts of the edging, which were set apart in advance for the required distance in accordance with the air temperature before installation. The supports are able to raise and lower the edges to the design height.
Недостатком известного устройства, вл етс невозможность использо1вани его при монтаже швов в мостах больщих пролетов, когда даже незначительные изменени температуры A disadvantage of the known device is the impossibility of using it when mounting joints in bridges of large spans, when even slight temperature changes
0 воздуха в процессе монтажа могут привести к разрушению анкерных соединений, развороту окаймлений или смещению их в плане, поскольку известное устройство не обеспечивает сохранность проектных положений окай5 млений в горизонтальной плоскости н не предотвращает разворот окаймлений в течение всего времени, необходимого на установку конструкций швов и их бетонирование.0 air during installation can lead to the destruction of anchor joints, reversal of edging or displacement in the plan, since the known device does not ensure the safety of the design positions of the edging in the horizontal plane and does not prevent the distortion of the edging during the entire time required for the installation of seams and their concreting.
Цель изобретени - обеспечение возможности производства работ независимо от изменени температурь воздуха.The purpose of the invention is to enable work to be carried out independently of changes in air temperature.
Указанна цель достигаетс тем, что в известной опорной раме дл монтажа конструкThis goal is achieved by the fact that in a known support frame for mounting the structure
