Description

Предметом изобретени   вл етс  железобетонна  трубчата  балкаверхн к дл  тра-пециевидной крепи при подготовительных выработках, арматура которой состоит ив металлических, продольно размещенных стержней, перехватываемых многогранной спиралью из металлического прута.The subject of the invention is a reinforced concrete tubular beam top for tra-specific support during preparatory workings, the reinforcement of which consists of metal, longitudinally placed rods intercepted by a multifaceted spiral of a metal rod.

Устройство подобных железобетонных труб, пзготовл емых центрифугированием , известно.The device of such reinforced concrete tubes prepared by centrifugation is known.

Отличительна  особенность описываемой балки-верхн ка заключаетс  в том, что в зоне раст жени  балки в качестве арматуры применен многожильный стальной канат. Таквм образом, в наиболее нагруженной зоне балки создаетс  лучшее сцепление между бетоном и арматурой , а следовательно, и большее сопротивление действию нагрузок.A distinctive feature of the described top beam is that in the stretching zone of the beam, a multicore steel wire is used as reinforcement. Thus, in the most loaded zone of the beam, a better adhesion between concrete and reinforcement, and consequently, greater resistance to loads, is created.

На фиг. 1 изображена описываема  балка-верхн к в ,ем виде; на фиг. 2 - то же, вразрезе по .4-.4 иа фиг. 1; на фиг. 3 - металлический каркас.FIG. 1 depicts the described beam-top to in, it is; in fig. 2 - the same, contrary to .4-.4 and figs. one; in fig. 3 - metal frame.

Балка-верхн к представл ет железобетонную трубу /, арматура которой состоит И8 рабочих стержней 2, коротких стержней 3 и многогранной спирали 4 (фиг. 1, 2 и 3).Beam-top to represents a reinforced concrete pipe /, the reinforcement of which consists of I8 working rods 2, short rods 3 and a multifaceted spiral 4 (Figs. 1, 2 and 3).

Многогранна  снираль 4 имеет шаг, равный 40-50 мм в пролете балки п 10 лиг - в опорах (на концах длиною 150 мм) верхн ка. Рабочие стержни 2 арматуры делаютс  из прутковоГ сталп № 3 и 5 и пр де изнопаенного каната.The multifaceted ribbing 4 has a pitch equal to 40-50 mm in the span of the beam and 10 leagues - in the supports (at the ends of a length of 150 mm) the top. The working rods 2 of the reinforcement are made of rod stal no. 3 and 5, and also made of a foam rope.

Стержни из пр дей изношенного каната расположены в раст нутой зоне, в углах монтажной арматуры, наиболее удаленных от. нейтральной осп изгиба. Два стержн  из ирутково стали расположены к сжатой и два в раст нутой зонах.Rods from a worn rope strand are located in the stretched zone, in the corners of the installation fittings furthest from. neutral pox bending. Two rods of irutkovo steel are located to the compressed and two in the extended zones.

Свободные углы в монтажной арматуре между стержн ми 2 в опорахверхн ка заполн ютс  короткими монтажными стержн ми 3.The free angles in the mounting fixture between the rods 2 in the upper supports are filled with short mounting rods 3.

Неровна  поверхность пр дей (образованна  свивкой проволок в пр дь) обеспечивает хорошее сцепление их с бетоном.The uneven surface of the strands (formed by twisting the wires into the strands) ensures their good adhesion to the concrete.
