![]() Reinforcement bar
专利摘要:
A concrete-reinforcement bar, especially a tension bar, provided with hot-rolled, helically-arranged ribs (2), which are located on two mutually-facing sides of the periphery of the bar and form parts of a thread. The ribs of the thread (2) extend over roughly a third of the periphery of the bar and are inclined toward one another with their front faces (4) which merge into the smooth bar surface of the core cross section (5). In order to improve the fatigue strength and mechanical strength, and to simplify the production of the threaded bars (1) and reduce the required tolerances, the cross-section of the bar (1) has a regular, smooth undulating profile in an axial plane in the region of each rib (2); the wave-shaped tops of the ribs (2) and the valleys between the ribs (2) thus form cavities (3) in the otherwise circular core cross-section (5). The cavities (3) penetrate into the core cross-section only at localized points. 公开号:SU1558305A3 申请号:SU874028843 申请日:1987-01-14 公开日:1990-04-15 发明作者:Финстервальдер Др.Ульрих 申请人:Др.

я СД СД О© о ся > ы Фиг 1 1558305 Изобретение относится к арматурным элементам для железобетонных конструкций. Целью изобретения является повыше- $ ние прочности арматурного стержня и упрощение его изготовления. На фиг. 1 схематично изображен арматурный стержень, частичный продольный разрез; на фиг. 2 - разрез А-А ю на фиг. 1;. на фиг. 3 - вид Б на фиг.1. Арматурный стержень содержит сердечник 1, на двух противоположных сторонах которого расположены горячекатаные ребра 2, ориентированные по вин-Л5 товой линии с образованием на одной трети периметра стержня части резьбы, торцы 3 которых наклонны и сопряжены с поверхностью сердечника 1. Впадины 4 между ребрами 2 расположены напро- 20 тив ребер 2 на противоположной стороне сердечника 1 с сохранением постоянной площади поперечного сечения по длине стержня. Ребра 2 выполнены скругленными с образованием совмест- 25 но: ‘ с впадинами 4 правильного волнообразного профиля, при этом впадины 4 образуют углубления 5 в круглом поперечном сечении сердечника 1. Расположение впадин 4 напротив ре- зо бер 2 на противоположной стороне сердечника с сохранением постоянной плодади поперечного сечения по длине стержня не приводит к ослаблению поперечного сечения стержня, что повышает его прочность и. выносливость при знакопеременных нагрузках. При этом также могут быть уменьшены допуски для винтовых муфт, с помощью которых такие стержни соединяются между собой. Кроме того, такая форма стержня упрощает его изготовление прокаткой, так как улучшаются условия заполнения винтовых ребер металлом. The invention relates to the construction and can be used for the reinforcement of reinforced concrete structures. In order to increase the strength of the reinforcing bar and simplify its manufacturing, the core is made with core 1 and rounded hot rolled ribs 2, which together with hollows 4 form indentations in the core and the correct wave-shaped cross-section profile of the rod, 3 sludge. I SD SD About © about camping > s Fig 1 1558305 The invention relates to reinforcing elements for reinforced concrete structures. The aim of the invention is to increase the strength of the rebar and simplify its manufacture. FIG. 1 schematically shows a reinforcing bar, a partial longitudinal section; in fig. 2 shows a section A - A of FIG. one;. in fig. 3 is a view of B in FIG. The rebar contains a core 1, on two opposite sides of which there are hot-rolled ribs 2 oriented along the win-L5 line to form a part of the thread on one third of the perimeter of the rod, the ends of which 3 are inclined and connected to the surface of the core 1. The hollows 4 between the ribs 2 are located In contrast, the ribs 2 are on the opposite side of the core 1 while maintaining a constant cross-sectional area along the length of the rod. The ribs 2 are rounded to form jointly: 'with the depressions 4 of a regular undulating profile, with the depressions 4 forming depressions 5 in the circular cross-section of the core 1. The location of the depressions 4 opposite the resober 2 on the opposite side of the core while maintaining a constant fruit of the cross section along the length of the rod does not weaken the cross section of the rod, which increases its strength and. endurance with alternating loads. At the same time, tolerances for screw couplings with which such rods are interconnected can also be reduced. In addition, this form of the rod simplifies its manufacture by rolling, as the conditions for filling the spiral ribs with metal are improved.
