Embodiment Construction

[0021] The present invention is described in detail below in conjunction with accompanying drawing:

[0022]A formwork system for concrete pouring of turned beams on raft foundations, including a raft foundation steel skeleton 1, on which the main reinforcement 2 of the turned beam and the stirrup 3 of the turned beam are arranged, and the precast valve plate On the upturning beam stirrup 3 at the connection with the precast upturning beam, along the left and right horizontal directions, the left inner piercing sleeve 4 of the lower tension bolt and the right inner piercing sleeve 5 of the lower tension bolt are respectively welded, The central axis of the left inner threading sleeve 4 of the lower pair of pull bolts coincides with the central axis of the right inner threading sleeve 5 of the lower pair of pull bolts. On the upper side, there is a lower limit steel plate 6 on the inner side of the left formwork connected by welding, and on the outer wall of the right end of th...

Abstract

The invention discloses a concrete pouring formwork system of a raft foundation upturning beam. The problem that an existing upturning beam hanging formwork is prone to shifting and expanding is solved. A supporting system of a concrete pouring formwork of the upturning beam is constructed on a main rib of the upturning beam, a combined sleeve assembly is used for constructing a square fixing frame for supporting and clamping formworks on the two sides of the upturning beam, the two formworks are clamped through fixing nuts at the two ends of an upper split screw and the two ends of a lower split screw, sleeves are welded to the main rib of the upturning beam, and split bolts are connected into the two sleeves in a penetrating mode and serve as supports of the formworks on the two sides of the upturning beam. Formwork shifting of the middle side formworks in integral pouring of a raft and the upturning beam is avoided, and the formwork system is convenient to assemble and disassemble.

Description

technical field [0001] The invention relates to a turning beam on a raft foundation, in particular to a concrete pouring formwork system for a turning beam on a raft foundation and a method for erecting the formwork system. Background technique [0002] The raft foundation and the upturned beam on it are generally completed by one-time pouring as a whole. The concrete pouring formwork of the upturned beam can only be fixed by hanging the formwork. The upper part of the hanging formwork is fixed with steel wires, and the middle part of the hanging formwork is equipped with pull bolts according to the height of the formwork to achieve the purpose of fixing the concrete pouring formwork of the upper turning beam. The side formwork is reinforced with wooden keels to prevent formwork deformation and expansion. The formwork phenomenon occurs; the formwork support method of the upper part of the formwork with cable-stayed steel wire and the bottom tie rod has poor stability. When t...
