Description
Technical Field
The utility model relates to a cast-in-place beam form setting construction technical field particularly, relates to a replace and wear mould to stay bolt and step by step tight reinforced (rfd) template fixture.
Background
In the conventional cast-in-place frame and frame-shear wall structure system at present, the manufacturing and installation of template engineering occupy a very large proportion in building construction, and each cubic concrete member needs 4-5 m2 of templates on average. The cost of the resources consumed by the formwork engineering in the general beam slab, frame and slab wall structures is about 30 percent of the total construction cost of the concrete structure engineering, the labor input accounts for 28 to 45 percent, and the method is of great importance to the cost and benefit of the whole building. Meanwhile, the concrete structure is directly contacted with the template and is formed by the mold frame system, and the manufacturing and installation quality of the template system directly influences the solid quality and the appearance effect of the concrete structure. Therefore, the adoption of a safe, reliable, economic and reasonable formwork process has very important significance for ensuring the molding requirement of the concrete member, improving the working efficiency, reducing the engineering cost and realizing safe and civilized construction.
In the traditional process, a cast-in-place beam formwork system is generally assembled and installed by a panel, primary and secondary keels, a through formwork split bolt and steps. The beam side and bottom plate adopts multilayer wood-rubber plates, the secondary keel at the beam side adopts 50 × 80mm longitudinal through-length square timber, the main keel adopts double-root phi 48 × 3.5mm steel pipes or 50 × 100mm square timber, and the side mold utilizes M12 or M14 through-mold bolts to carry out opposite pulling unloading. The bottom of the beam is longitudinally provided with 50 × 80mm square timber as a secondary keel, the main keel is provided with a steel pipe bracket cross rod with a diameter of 48 × 3.5mm, the two sides of the bottom of the beam are provided with the secondary keel for clamping the lower layer of the side mold of the beam step by step, and the step-by-step distance is not more than 600 mm.
The method for reinforcing the cast-in-place beam template by utilizing the through-die split bolts and tightening the through-die split bolts in steps has many problems in actual use, and the concrete expression is as follows:
1. bolt through holes are drilled in the beam side die when the counter bolts are used for installing the template each time, the labor cost is increased by repeatedly drilling, the integrity and the tightness of a panel are damaged, slurry leakage is caused in concrete pouring, the impression effect of the formed component is influenced, the turnover frequency of the side die is low, and the material loss rate is high; and the sawdust residues generated by drilling the template are left in the template and are not easy to clean, so that the structural defect is formed, and the solid quality of the concrete member is directly influenced.
2. The split screw is buried in the concrete and cannot be taken out, so that the consumption of disposable materials is huge, the template dismantling process is very difficult, the template is very easy to damage, and the material waste is caused; if the split bolt needs to be used in a turnover mode, the PVC sleeve pipe needs to be additionally arranged in the beam, a through hole is formed in the component after the split screw rod is taken out, the inner wall of the PVC sleeve pipe is smooth, the PVC sleeve pipe is poor in adhesion with concrete, the field is not easy to seal tightly, or sealing water is omitted, and the hidden danger of leakage is increased.
3. For basement and outdoor cast-in-place beam formwork, water-stop split bolts are required, and the screw rods are thrown once, so that the material consumption is increased.
4. The template is reinforced by tightening step by step, so that the phenomenon of expansion and slurry leakage caused by incomplete reinforcement is easily caused, the method is basically feasible for the beam with smaller section size, but cannot guarantee enough concrete side pressure for the beam with the section height of more than 700mm, the structural safety and the reinforcing quality are difficult to effectively guarantee, and the problem is not easy to find.
5. Step tightening only plays the clamping action to the lower floor secondary joist of roof beam side form, consolidates area and scope for a short time, and because the step tightening below of beam bottom is unsettled, lacks effectual drawknot fixed measure, and the vibrations that the concrete vibrates the in-process and produces cause step tightening or loosening easily and become invalid, leads to the quality accident that the mould causes that rises in the side form bottom.
6. The main keel of the side mould generally adopts double steel pipes with the diameter phi of 48 × 3.5mm or square wood with the diameter of 50 × 100mm, and the short steel pipes adopt a leasing mode, so that the field consumption is large, and the leasing cost is high; the square timber saw is easy to lose after being short, has high loss rate, and cannot be used for other components in a circulating way, thereby causing material waste.
