PRODUCTION LINE FOR FABRICATING LONG BUILDING STRUCTURES AND CROSS BAR, COLUMN, BEAM FABRICATED USING SAID PRODUCTION LINE

摘要

The invention relates to construction industry, in particular, to units for fabricating long building structures using non-tensioned and pre-stressed reinforcement including cross bars, columns and beams and can be used in erection of residential, public and administrative buildings and structures as well as restoration and reconstruction thereof. According to the invention, the production line for fabricating building structures, preferably cross bars, beams comprises at least one concrete distributor, devices for delivering and mounting reinforcement and formwork made as pallet box combined into a common system forming at least two adjacent extended longitudinal forming cavities for corresponding preferably simultaneously fabricated building structures made from hardening material with reinforcement, mainly reinforced concrete, wherein the adjacent forming cavities of the formwork are separated by common central longitudinal board with two forming surfaces rigidly fixed on the pallet, while the longitudinal outer boards are made dropped adapted to return to the initial position changing the working width of each forming cavity from maximum to at least 0.3 of its maximum value and fixing in the required positions, the pallet is mounted using discrete supports enabling adjustment of pallet height position on supports with fixing, at least, against longitudinal displacements in the central part and against directed sliding from the central part at least along the length at temperature deformations, the formwork comprises a set of forming cut-off reusable diaphragms of different dimension types corresponding to the dimension types of the cross sections of being fabricated building structures. The described production line can be used for fabricating cross bars, columns and beams made from hardening material with reinforcement, mainly reinforced concrete. The technical result of the invention is aimed at reducing usage of materials and labor input, possibility to execute operations under any weather conditions, predominantly in regions related to rigorous climatic zones with low negative temperatures in winter season with simultaneous reduction of time of execution of work, production of reliable structures with improved technological features and better quality.
