Description
При изготовлении предварительно напр женных железобетонных изделий в известных устройствах дл нат жени арматуры с помощью металлического стержн , включенного дл нагрева в электрическую цепь и служащего, т говым органом дл арматуры, имеют место большие потери тепла при нагреве стержн и расходуетс дополнительное врем на его охлаждение.In the manufacture of prestressed reinforced concrete products in the known devices for tensioning reinforcement with a metal rod included for heating into an electrical circuit and serving as a traction body for reinforcement, large heat losses occur during heating of the rod and additional time is spent on its cooling.
Описываемое устройство не имеет этих недостатков.The described device does not have these disadvantages.
Сущность изобретени заключаетс в том, что стержень, служащий т говым органом, заключен в кожух, снабженный теплоизол цией и вентил ционным устройством. Это уменьшает потери тепла при нагреве стержн и ускор ет процесс его охлаждени .The essence of the invention lies in the fact that the rod, which serves as a traction member, is enclosed in a casing, provided with thermal insulation and a ventilation device. This reduces heat losses during heating of the rod and accelerates its cooling process.
На чертеже схематически изображено описываемое устройство дл нат жени арматуры электротермическим способом.The drawing shows schematically the described device for tensioning the reinforcement by electrothermal method.
Т говый стержень / находитс внутри кожуха 2, снабженного теплоизол цией 3. К концу стержн присоединен зацеп 4, изолированный от самого стержн .The pull rod / is located inside the housing 2 provided with thermal insulation 3. A hook 4 is attached to the end of the rod, insulated from the rod itself.
Кожух 2 установлен на опорах 5 и имеет штуцер 6 дл подсоединени вентил тора. Внутри кожуха расположены выступы 7, выполненные из теплостойкого и непровод щего ток материала. Назначение выступов - предотвратить прогиб т гового стержн под собственным весом. Форму 8 с уложенной в ней арматурой 9 располагают напротив т гового стержн /. Концы арматуры зажимают приспособлением JO, которое снабжено плитой // с прорезью 12.The casing 2 is mounted on the supports 5 and has a fitting 6 for connecting the fan. Inside the housing there are protrusions 7, made of heat-resistant and non-conductive material. The purpose of the protrusions is to prevent the bending rod from bending under its own weight. Form 8 with fittings 9 placed in it is placed opposite the draw rod /. The ends of the reinforcement clamp fixture JO, which is equipped with a plate // with a slot 12.
Нри прохождении электрического тока, т говый стержень нагреваетс и удлин етс . Зацеп 4, продвига сь по плите 11, попадает в прорезь 12. После выключени тока т говый стержень сжимаетс и приводит в движение зацеп 4 и плиту // и нат гивает арматуру. По достижении необходимого нат жени арматуру 9 закрепл ют на форме зажимами 13, отпускают зажимы приспособлени 10 к форму направл ют на бетонирование .By passing an electric current, the pull rod is heated and lengthened. The hook 4, advancing along plate 11, falls into slot 12. After the current is turned off, the draw rod contracts and causes the hook 4 and plate // to move, and tension the reinforcement. Upon reaching the required tension, the reinforcement 9 is fixed on the mold with clips 13, the clamps of the tool 10 are released to the mold are directed to concreting.
