DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] The terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present utility model are only for the convenience of description and are not used to limit the scope of application of the present utility model. Changes or adjustments in their relative relationships shall be regarded as the scope of application of the present utility model without substantially changing the technical content.

[0024] Reference Figure 1-Figure 3 A prefabricated composite panel top grooving tool comprises a bottom tire mold 1 and a prefabricated composite panel body 13. The bottom of the bottom tire mold 1 is provided with an installation groove, in which an embedded channel steel 5 is fixedly arranged. Two embedded bolts 4 are fixedly connected to the upper surface of the embedded channel steel 5. A side template 6 is installed on the upper surface of the bottom tire mold 1. A plurality of grooves are provided on the side template 6. A grooved wooden board 7 is arranged in each groove. A steel frame 2 is installed above the bottom tire mold 1. The steel frame 2 reasonably selects the model and size of the material according to the span size of the composite panel. Generally, it can be welded with national standard channel steel, I-beam or H-beam with a number between 14# and 25#. If the span is large, double-piece channel steel can also be used. Two fixing bolts 3 are arranged on the steel frame 2. The steel frame 2 is connected by two first nuts 11 and two embedded bolts 4. A grooved channel steel 9 is arranged on the top of the plurality of grooved wooden boards 7, and a jack 8 is arranged between the steel frame 2 and the grooved channel steel 9.

[0025] The steel frame 2 is provided with two mounting holes 12 for connecting the embedded bolts 4, each first nut 11 is threadedly connected to the corresponding embedded bolt 4, the steel frame 2 is provided with two through holes for inserting the fixing bolts 3, the steel frame 2 is fixedly connected with a plurality of threaded nuts 10, the plurality of threaded nuts 10 are symmetrically arranged, each fixing bolt 3 is threadedly connected to the corresponding threaded nut 10, the bottom tire mold 1 is cast by concrete, the concrete grade is selected to be C20 or above, the surface is smoothed, and the surface flatness is controlled by a long aluminum alloy scraper, and the cover The film is applied and watered for 14 days. If the bottom mold 1 has many cracks, surface treatment is required. The edge line of the template is released with an ink fountain, and the bottom mold 1 is painted with a release agent or template oil. Cover it with plastic oil paper to prevent dust accumulation, so that the bottom mold 1 can fully absorb the release agent or template oil. The side template 6 is made of steel, and the grooved wooden board 7 is made of pine wood. The grooved wooden board 7 is made of hard and light material due to the high frequency of manual handling during construction. Therefore, it is more appropriate to use wooden squares, and it is more appropriate to choose pine wood with a moderate moisture content.

[0026] In the utility model, according to the construction sequence of the prefabricated composite slab, after the reinforcement of the prefabricated composite slab is tied and the formwork is installed, the steel frame 2 can be installed. The steel frame 2 is made of welded steel and has good rigidity and stability. The steel frame 2 is provided with mounting holes 12, so that the upper ends of the embedded bolts 4 pass through the corresponding mounting holes 12, so that the embedded bolts 4 are threadedly connected with the first nuts 11, and the steel frame 2 can be firmly fixed on the ground. At the same time, since the embedded bolts 4 are welded with the embedded channel steels 5, the steel frame 2 has good pull-out resistance. After the concrete of the prefabricated composite slab is poured, the grooved wooden board 7 should be immediately laid in the groove of the side formwork 6. Since the concrete itself has a large density and a certain buoyancy, it is difficult for the grooved wooden board 7 to be pressed into the groove. The grooved channel steel 9 is laid on the top of the grooved wooden board 7. The grooved channel steel 9 can choose I-beams or H-shaped steels between 14# and 18#.

[0027] Place the jack 8 between the steel frame 2 and the grooved channel steel 9, start the jack 8, and the extrusion force of the jack 8 is evenly transmitted to the grooved wooden board 7 through the grooved channel steel 9, and then the grooved wooden board 7 is pressed into the groove to squeeze out the excess concrete from the surface. After the groove is in place, turn each fixing bolt 3, the fixing bolt 3 and the threaded nut 10 are threadedly connected, and the fixing bolt 3 is tightened. The bottom surface of the fixing bolt 3 and the surface of the grooved channel steel 9 are tightly attached to fix the continuous pressure, and then the jack 8 is unloaded, and the jack 8 can flow to the next board, a total of During construction, the concrete surface should be finished and smoothed. When the concrete is about to set, the grooved channel steel 9 and the grooved wooden board 7 should be removed in time to prevent the concrete from sticking to the grooved wooden board 7. When removing, loosen the fixing bolts 3 on both sides evenly, and then remove the first nut 11 of the embedded bolt 4, dismantle the steel frame 2 as a whole, and transfer to the next board construction after maintenance. After final setting, the surface should be roughened in time according to the strength change, which can effectively avoid the groove from being deformed and changing, affecting the visual quality and molding effect, and can also prevent the groove from being inconsistent in specifications.

[0028] In the present invention, unless otherwise clearly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense.
