Description

Technical Field

[0001] This application relates to the technical field of the production of T-beam steel cages, and particularly to an integral forming movable formwork for precast T-beam steel cages and a construction method thereof. Background Art

[0002] Currently, the process of binding the steel bars of precast T-beams generally involves separately binding the top plate and web steel bars of the T-beam, and then integrally connecting the top plate and web steel bars within the formwork. The defects of this method are as follows: The top plate and web steel bars of precast T-beams need to be fabricated on their respective precast pedestals, which takes a long time to occupy the precast pedestals and T-beam formwork, occupies a relatively large amount of site space, and is not conducive to the turnover and utilization of T-beam pedestals and T-beam formwork; in addition, although the method of binding steel bars using a formwork ensures the turnover and utilization of T-beam pedestals to a certain extent, the existing formwork is of a fixed style, and the spacing support rods (grooves) of the steel bars of the formwork are not adjustable. Each formwork is applicable to one type of steel cage and does not have multiple applicability, which affects the long-term recycling of the formwork.

[0003] In view of this, there is an urgent need for a steel bar formwork construction structure and construction method that is convenient for disassembly and assembly, has a fast construction speed, strong applicability, high positioning accuracy, and can realize the integral binding and forming of T-beam steel bars.

Construction pedestal (2) and accessory components: Pour a concrete pedestal (2) on the leveled and compacted ground (1), set a reserved groove (3), fixed vertical rods (6), fixed tooth grooves (8) on the pedestal (2), and pour a limit block (10) at a set position far from the left end of the pedestal (2); S10. Install the guide rail (11): Set a strip-shaped guide rail (11) at the right end adjacent to the pedestal (2), and install a limit rod (12) at the right end of the guide rail (11); S20. Install the movable vertical rod (13) and the diagonal brace (16): Install the movable vertical rod (13) in the reserved groove (3), connect the diagonal brace (16) to the upper part of the movable vertical rod (13), and the lower part of the diagonal brace (16) abuts against the right end of the limit block (10); S30. Install the post-installed vertical rod (17); Sleeve the post-installed vertical rod (17) on the fixed vertical rod (6), and install the left cross brace (19) of the post-installed vertical rod (17) in the right sleeve (15) of the movable vertical rod (13); S40. Install the movable tooth groove (27): Install a suitable movable tooth groove (27) on the fixed tooth groove (8), and use the upper notch of the movable tooth groove (27) as the stirrup positioning groove (31); S50. Install the movable formwork (21): Install the movable formwork (21) on the guide rail (11) so that the movable formwork (21) can move in the length direction of the guide rail (11), move the movable formwork (21) to the left to make the movable formwork (21) in the working position, and fix the movable formwork (21) with a temporary diagonal brace (26); S60. Install adjustable supports (33): Install movable sleeves (32) at the tops of the movable vertical poles (13), the first vertical pole (23) and the second vertical pole (24) of the mobile formwork (21), and install adjustable supports (33) in the top grooves of the movable sleeves (32); S70. Install the top plate formwork: Install lower layer longitudinal bar positioning rods (34) on the adjustable supports (33), and sleeved the two ends of the upper layer longitudinal bar positioning rods (37) on the two ends of the lower layer longitudinal bar positioning rods (34) through connecting vertical poles (35) and connecting sleeves (36), and install two stirrup positioning plates (39) at the two ends of the upper and lower longitudinal bar positioning rods; S80. Integrally bind the steel bars: Position the stirrups of the T-beam web through the stirrup positioning grooves (31) of the movable tooth grooves (27), position the longitudinal bars of the T-beam web through the longitudinal bar positioning rods (20) of the later-installed vertical poles (17), position the longitudinal bars of the T-beam top plate through the longitudinal bar grooves (38) of the top plate formwork, and position the stirrups of the T-beam top plate through the stirrup positioning plates (39) of the top plate formwork, so as to integrally bind the web steel bars and the top plate steel bars of the T-beam; S90. Remove the top plate formwork: After the binding is completed, remove the upper layer longitudinal bar positioning rods (37), the lower layer longitudinal bar positioning rods (34) and the stirrup positioning plates (39) of the top plate formwork; S100. Move out the mobile formwork (21): Move the mobile formwork (21) to the right to move it out of the working position; S110. Hoist the steel bars integrally: Hoist the integrally formed T-beam steel bars out.
