Problems solved by technology

[0002] The existing conventional steel bar stools are welded by steel bars to process corresponding supporting steel parts. During construction, the steel bars are not displaced by the support function. The construction of such a horse stool is cumbersome and requires a large amount of steel bar binding construction to fix the stressed steel bars. It affects the construction efficiency and construction quality, especially for the large-volume concrete pouring of bridges, the pressure is high, and the requirements for steel parts are high. The general horse stool is easy to be out of shape and deformed, and it is difficult to adjust the support distance of the horse stool, which makes the construction difficult. increase

Abstract

The invention provides a horse stool device for bridge large-size concrete pouring. The horse stool device comprises longitudinal rebars, transverse rebars and a concave horse stool and is characterized in that the concave horse stool comprises at least two hinged cross support rods forming multiple cross support pairs, an adjustment clasp is arranged between at least one cross support pair, one end of the adjustment clasp is fixedly hinged to one of the cross support rods, the other end of the adjustment clasp is an annular buckle with which the other cross support rod is sleeved, one ends ofthe cross support rods are provided with vertical threaded rods connected to adjustable support feet, and high-strength threaded sleeves and horse stool rebars are manufactured in a certain processing method. The horse stool device for bridge large-size concrete pouring is a small structural accessory which can be produced on a large scale, is small in size, convenient to store and process, fastin operation and high in universality, and can save materials compared with a welded horse stool under the same conditions. Construction is convenient, simple and easy to handle and operate.
