Embodiment Construction

[0019] This embodiment discloses a hydraulic formwork trolley used for post-cast construction of a rail-top air duct, which mainly includes a formwork system and a support system.

[0020] Such as figure 1 , figure 2 As shown, the template system includes a template 1 and its supporting members 2, a retracting and erecting mold mechanism 3, and a transverse beam 4.

[0021] Such as figure 1 , image 3 As shown, the template 1 includes a bottom mold 11, an outer movable mold 12 and an inner movable mold 13. The bottom mold 11 is made of H-shaped steel, and the outer movable mold 12 includes an outer template 121 and a number of outer connecting frames 122 longitudinally arranged along the outer side.

[0022] The outer template 121 includes a lower fixed-length mold 1211 and an upper movable mold 1212 connected to its upper end by bolts. The lower side of the lower fixed-length mold 1212 is hinged to a steel plate welded at a corresponding position of the bottom mold 11 through an ea...

Abstract

The invention discloses a hydraulic formwork trolley for rail top air duct post-pouring construction. The hydraulic formwork trolley mainly comprises a support system and a formwork system connected to the upper end of the support system, the formwork system comprises a bottom formwork, an inner side moving formwork and an outer side moving formwork which are hinged to the two sides of the bottom formwork and a formwork collecting oil cylinder. The bottom formwork, the inner side moving formwork and the outer side moving formwork are all integral parts, the number of modules is small, and the concrete forming effect is good. The support system comprises a support and an automatic lifting mechanism and an automatic walking mechanism which are at the bottom of the support, the automatic lifting mechanism achieves integral lifting of the trolley, and the automatic walking mechanism achieves integral longitudinal movement. Hinged assembling is quick and high in efficiency, large lifting equipment is not needed, the occupied space is less, and narrow underground construction requirements can be met. After a section is poured, the outer side moving formwork and the inner side moving formwork are rotated to be open through the formwork collecting oil cylinder to get away from the concrete, the height of the support system is controlled to be lowered to enable the bottom formwork to get away from the concrete, the trolley is directly controlled to move to the next to-be-poured section, and corresponding formwork erection operation can be conducted.

Description

Technical field [0001] The invention relates to a rail-top air duct of a subway station, in particular to a hydraulic formwork trolley used for post-pouring construction of the rail-top air duct. Background technique [0002] In the subway station structure, the rail-top air duct is responsible for the exhaust and supply of the subway air. It is an important part of the subway station structure and directly affects the normal operation of the subway train. At present, most subways are constructed by shield machine, and the shield machine will interfere with the rail top air duct when passing the subway station during the construction process. Therefore, the rail top air duct is usually constructed by post-casting. When pouring the rail-top air duct, it is usually constructed with a combination of full-frame brackets and small steel or wooden molds. Obviously, this construction method has problems such as large workload of erecting and dismantling the bracket, high construction c...
