A kind of steel pipe arch bridge hanger installation simulation device and using method

Abstract

The invention discloses a steel pipe arched bridge suspender mounting simulation device and a use method. The steel pipe arched bridge suspender mounting simulation device comprises an arch rib steeltube, an arch rib sleeve, an arch rib sleeve anchor bearing plate, a laser transmitter fixing rack, a laser pulse transmitter, a data analyzer, a total reflection prism, a tie beam and a tie beam sleeve; the arch rib sleeve is nested in the arch rib steel tube; the arch rib sleeve anchor bearing plate is welded at the front end of the arch rib sleeve; the laser transmitter fixing rack is fixedly connected to the arch rib sleeve anchor bearing plate and used for mounting and fixing the laser pulse transmitter; the transmitter plane of the laser pulse transmitter is parallel to the plane of thearch rib sleeve anchor bearing plate; the tie beam sleeve is nested in the tie beam; the total reflection prism is mounted at the rear end of the tie beam sleeve; and the data analyzer can read laserbeams received by the laser pulse transmitter and the receiving time. Through adoption of the steel pipe arched bridge suspender mounting simulation device, whether the positions of a steel tube archrib and a tie beam embedded sleeve satisfy mounting requirements of a suspender or not and the actual cutting length of the suspender can be measured before the suspender is mounted; and therefore, the suspender mounting and cutting accuracy is improved and the construction efficiency is enhanced.

Description

technical field [0001] The invention belongs to the technical field of steel pipe arch bridge construction, and in particular relates to a steel pipe arch bridge suspender installation simulation device and a use method. Background technique [0002] The error between the processing length of the steel pipe arch suspender and the length of the actual installation should not exceed 100mm. If this distance is exceeded, the suspender will be returned to the factory for reprocessing, resulting in waste of materials and construction period, and certain difficulties in production. At present, before the production of steel pipe arch blanking, tape measure is mostly used to measure in advance, but the stretching and bending deformation of tape measure will bring certain errors to the measurement, which affects the precision of blanking of boom. At the same time, since the installation and construction of the arch-rib steel pipe will inevitably cause various errors, it is very likel...

Problems solved by technology

[0003] In order to overcome the technical defects in the prior art, such as the difficulty in accurately controlling the blanking length of the steel pipe arch bridge suspender, and the large error in the installation process of the suspender, the present invention provides a steel pipe arch bridge suspender installation simulation device and a method of use, with the aid of a laser pulse transmitter And the total reflection prism can measure whether the position of the steel pipe arch rib and the embedded casing of the tie beam meets the installation requirements of the boom and the actual blanking length of the boom before the installation of the boom, so as to improve the accuracy of the installation of the boom and the blanking of the boom , improve the efficiency of boom construction
