DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Reference Figure 1-Figure 7 A prefabricated PCF board forming device includes a forming bottom plate 1, and a plurality of long side plates 2 and a plurality of short side plates 3 are arranged on the upper side of the forming bottom plate 1. The long side plates 2 and the short side plates 3 surround a forming cavity, and the forming cavity serves as a forming container for the PCF board. The PCF board is a prefabricated concrete wall panel, also known as a prefabricated wall sandwich panel or a prefabricated sandwich wall panel. It is mainly made of concrete.

[0034] In order to prevent the temperature of the concrete of the molding bottom plate 1 from being lost quickly and causing the concrete to solidify too quickly, a thermal insulation film 4 is laid at the bottom of the molding cavity, and a steel structure skeleton 5 is arranged on the upper layer of the thermal insulation film 4 .

[0035] Specifically, the steel structure skeleton 5 includes a transverse assembly frame 501 and bundled steel bars 502. The transverse assembly frame 501 includes transverse steel bars and longitudinal steel bars. The transverse steel bars and longitudinal steel bars are arranged at equal intervals, and the transverse steel bars and the longitudinal steel bars are connected by steel wire bundling. The bundled steel bars 502 are evenly distributed on the transverse assembly frame 501, and the bundled steel bars 502 are connected to the transverse steel bars and the longitudinal steel bars by steel wire bundling.

[0036] The steel structure skeleton 5 exists as an internal skeleton of the PCF board, and can improve the strength and other properties of the formed PCF board.

[0037] An operating table 6 and a position adjustment unit 7 are provided on the upper side of the forming base plate 1 . The position adjustment unit 7 is used to adjust the position of the operating table 6 . Specifically, the position adjustment unit 7 is provided on the long side plate 2 , and is used to drive the operating table 6 to move along the long side plate 2 .

[0038] More specifically, the position adjustment unit 7 includes a position adjustment housing and a position adjustment motor. A position adjustment screw is arranged inside the position adjustment housing. The position adjustment screw is threadedly connected to a position adjustment nut. The position adjustment nut is slidably installed inside the position adjustment housing. The position adjustment screw is connected to the output end of the position adjustment motor, and the position adjustment nut is connected to the operating table 6.

[0039] In order to make the operating table 6 move more smoothly, an auxiliary guide unit 8 is provided on the long side panel 2. The auxiliary guide unit 8 includes an auxiliary rail and an auxiliary slider. The auxiliary rail is parallel to the position adjustment shell, and the auxiliary rail is slidably connected to the auxiliary slider, and the auxiliary slider is connected to the operating table 6.

[0040] A mounting frame 12 is disposed on the operating table 6 , and an extension and contraction unit 13 and a vibrating device 14 are disposed on one side of the mounting frame 12 . The extension and contraction unit 13 is used to adjust the distance between the vibrating device 14 and the mounting frame 12 .

[0041] Specifically, the extension and contraction unit 13 includes a base 1301, a rotating shaft 1302, and a driving motor. The rotating shaft 1302 is inserted into the base 1301, and the output end of the driving motor is connected to the rotating shaft 1302. The rotating shaft 1302 is connected to two primary plates 1303. A contraction component 1304 is provided in the primary plate 1303. The contraction component 1304 is connected to a secondary plate 1305. The contraction component 1304 is used to adjust the depth of the secondary plate 1305 inserted into the primary plate 1303. A vibrating device 14 is installed on the secondary plate 1305.

[0042] After the steel structure skeleton 5 is delivered into the molding cavity, concrete needs to be poured. The vibrating device 14 is used to remove bubbles in the concrete by vibrating after the concrete is poured. The shrinkage component 1304 can adjust the distance between the vibrating device 14 and the mounting frame 12, and the position adjustment unit 7 can adjust the position of the operating table 6 and the vibrating device 14 along the long side plate 2, so that the vibrating device 14 can cover multiple areas of the molding cavity to achieve vibration of the concrete. The mechanical vibration method replaces the manual vibration method in the traditional PCF board production process, thereby reducing the workload of operators during prefabricated board molding.

[0043] After the concrete is poured and the bubbles are removed by the vibrating device 14, in order to improve the thermal insulation performance of the formed PCF board, an insulation board 16 is arranged on the top of the forming cavity. The insulation board 16 needs to be pressed on the upper surface of the concrete before the concrete begins to set. The PCF board finally formed has good thermal insulation performance. With the thermal insulation film 4 at the bottom, the solidification time of the concrete is roughly the same at various locations, avoiding residual stress caused by different temperature differences, and the overall strength of the formed PCF board is stronger.

[0044] In order to keep the insulation board 16 in a stable position without displacement during the solidification of concrete, a positioning unit 15 is provided on the mounting frame 12. When the positioning unit 15 is activated, it presses on the upper side of the insulation board 16 to keep the insulation board 16 and the poured concrete in a stable position.

[0045] Specifically, the positioning unit 15 includes a side wall adjustment unit 1501, a horizontal plate 1502, and a pressing side wall 1503. The side wall adjustment unit 1501 is used to adjust the distance between the two pressing side walls 1503. The larger the distance, the larger the distance between the pressing side walls 1503. It is used to adjust the positioning point for pressing the insulation board 16. The side wall adjustment unit 1501 is connected to the pressing side wall 1503 through the horizontal plate 1502. The positioning unit 15 also includes a pressing plate 1504, which is arranged on the lower side of the mounting frame 12.

[0046] The insulation board 16 is pressed by the pressing plate 1504 and the two pressing side walls 1503, so that the position of the insulation board 16 and the poured concrete is relatively stable, thereby avoiding the position of the insulation board 16 to shift during the concrete solidification process. The positioning unit 15 itself is controlled by mechanical components, which is convenient to start and easy to operate during the separation process.

[0047] It should be noted that a reversing device 9 and a lifting unit 11 are provided on the operating table 6. The reversing device 9 is used to adjust the angle of the lifting unit 11. The output end of the lifting unit 11 is connected to the mounting frame 12. A support plate 10 is provided on the operating table 6. When the vibrating device 14 is started, the lower end surface of the mounting frame 12 is flush with the upper end surface of the support plate 10. In this way, the vibration generated during the operation of the vibrating device 14 can be borne by the mounting frame 12, the operating table 6 and other components, which has less destructive force on a single component and a longer service life of the entire device as a whole.

[0048] The reversing device 9 can drive the mounting frame 12 to rotate, so that the mounting frame 12 has at least three states including a vibrating state, a pressing state, and a retracted state. When the mounting frame 12 is in the vibrating state, the vibrating device 14 is aligned with the concrete poured in the molding cavity. When the mounting frame 12 is in the pressing state, the positioning unit 15 is aligned with the insulation board 16. When the mounting frame 12 is in the retracted state, the vibrating device 14 and the positioning unit 15 are staggered with the molding cavity up and down. It will not hinder the pouring of concrete.

[0049] The use of the prefabricated PCF board forming device includes the following steps:

[0050] Step 1: Assemble the mold. Install the long side plate 2 and the short side plate 3 on the molding base plate 1 by bolts. The long side plate 2 and the short side plate 3 surround the molding cavity.

[0051] Step 2: Spraying release agent;

[0052] Step 3: Laying the thermal insulation film 4 on the bottom of the molding cavity;

[0053] Step 4: Install the steel structure frame 5, place the steel structure frame 5 into the forming cavity through a lifting tool, and manually adjust the position of the steel structure frame 5;

[0054] Step 5: pouring concrete. Before pouring concrete, start the reversing device 9 to convert the mounting frame 12 into a retracted state;

[0055] Step 6: Remove bubbles in the concrete by vibrating. Start the reversing device 9 to drive the mounting frame 12 to rotate, and switch the mounting frame 12 to the vibrating state. At this time, the vibrating device 14 is aimed at the poured concrete. The position of the vibrating device 14 is adjusted by the position adjustment unit 7 and the contraction component 1304, so that the vibrating device 14 can screen out bubbles from the concrete in the molding cavity.

[0056] Step 7: Place the insulation board 16 into the molding cavity by using a lifting tool, and manually adjust the position of the insulation board 16;

[0057] Step 8: Pressurize the insulation board 16 until the concrete solidifies, start the reversing device 9, and convert the mounting frame 12 to the pressing state. The positioning unit 15 on the mounting frame 12 presses the insulation board 16 to fix the insulation board 16 relative to the concrete until the concrete solidifies;

[0058] Step nine: Curing the solidified concrete by steam curing to form the PCF board, then removing the long side board 2 and the short side board 3 and taking out the PCF board.
