Then, the steel bar truss floor slab template 5 is lifted into the pouring mold frame, and the bottom plate 52 is placed on the plurality of ejector rods 411 in a centered manner relative to the pouring mold frame, so that the bottom plate 52 is supported above the lower support template 11, and in the embodiment, the height supported by the plurality of ejector rods 411 is such that each lower chord steel bar 5112 is in a position horizontally aligned with the support sleeve 211 at an adjacent position; then, the two carry screws 23 are rotated again, so that the two short-side baffle templates 21 move towards each other, in the moving process, the two ends of the lower chord steel bar 5112 correspondingly insert into the bearing sleeves 211 at the corresponding positions in the two short-side baffle templates 21, it is to be noted that a certain relative movement contact distance is provided between the shifting shaft 451 and the single-side horizontal section of the guide hole 441, therefore, the lower chord steel bar 5112 moves to the position where the end of the lower chord steel bar 5112 contacts with the long-side baffle template 32 in a small-section moving distance process before the bearing sleeves 211 are inserted and after the short-side baffle templates 21 are inserted, the bearing height of the ejector rod 411 relative to the bottom plate 52 is kept unchanged, along with the movement of the short-side baffle templates 21, the shifting shaft 451 passes through the transition section of the guide hole 441 and relatively moves to the other horizontal section, the ejector rod 411 descends along with the ejector rod base plate 41, the top end of the ejector rod 411 is kept at the level with the upper end surface of the lower chord steel bar baffle template 11, when the two ends of the lower chord steel bar 5112 simultaneously contact with the vertical baffle plates 221 at the two sides, the inner plate screws 23 are stopped rotating, the short-side baffle templates 21 move again to the position where the end of the short-side baffle templates 32 face contacts with the long-side baffle templates, the trusses are positioned, the two short-side baffle templates 21 are placed on the middle floor frames are positioned in the middle, the two short-side frames are positioned in the direction of the steel bar trusses and the truss frames are positioned in the middle, the steel bar frames are positioned in the direction of the middle of the steel bar frames 5, and the steel bar frames are positioned in the middle, and the middle of the steel bar frames are positioned in the middle and the two side frames are positioned.
And then, concrete pouring is carried out in the pouring mold frame, and the pouring vibration table is synchronously used for vibrating, so that the pouring surface is slightly lower than the whole height of the pouring mold frame, and after pouring is finished, the poured device is integrally transferred to a maintenance area for maintaining and shaping the prefabricated mold plate.
Finally, after the shaping of the prefabricated form is completed, the two carry screws 23 can be manually rotated again, so that the two short-side blocking templates 21 move back, in the moving process, the two short-side blocking templates 21 automatically complete demolding and separation, and the two long-side blocking templates 32 synchronously complete demolding and separation therewith, in addition, the plurality of ejector rods 411 synchronously pass through the ejector rod holes 111 again, jack up the prefabricated form integrally upwards, and force the bottom end of the prefabricated form to complete demolding and separation with the lower supporting template 11.
The invention provides a steel bar truss floor slab template fixing device, which can replace the existing pouring template frame with a simple structure to be used for pouring and forming a prefabricated steel bar truss floor slab template 5, is provided with a pouring template frame consisting of a lower support template 11, a short side baffle template 21 and a long side baffle template 32, is matched with a jacking demoulding mechanism 4, can realize synchronous linkage adjustment of a long side baffle assembly 3 and the jacking demoulding mechanism 4 by simply adjusting the relative distance between the two short side baffle templates 21 in two side baffle bearing mechanisms 2, and can realize centering bearing and fixing of the steel bar truss floor slab template 5 through the two side baffle bearing mechanisms 2 on the basis that the jacking demoulding mechanism 4 provides auxiliary bearing, and can realize automatic assembly of the pouring template frame synchronously and realize rapid demoulding of the pouring template frame after pouring and forming; the problem that the height and the placement position need to be manually adjusted when the templates are placed is solved, the problem that the pouring mold frame needs to be manually assembled and disassembled is also solved, the operation is convenient, the quick assembly and the quick demoulding are realized, and the method is suitable for batch pouring molding operation.
