[0019] The following further describes the detailed embodiment of the present invention with reference to the drawings.
[0020] As Figures 1-6 shown, a construction formwork reinforcement fitting includes a side plate 5. Extension plates 6 are arranged at both ends of the side plate 5. Both extension plates 6 are located on the same side of the side plate 5. Each extension plate 6 is provided with a round hole 7. Extension grooves 8 that communicate with each other are arranged on both sides of the round hole 7. It further includes a bolt 9. Two wedge blocks 10 are symmetrically arranged at the lower end of the bolt 9. A protruding part that is matched with the round holes 7 on both extension plates 6 is arranged on the outer surface of the bolt 9. The protruding part is located above the wedge blocks 10. A handle 11 is arranged at the upper end of the bolt 9. A screw rod 12 is arranged on one side of the side plate 5. The side plate 5 is located between the screw rod 12 and the extension plate 6. A nut 13 is threadedly connected to the screw rod 12. It further includes a limit plate 14. A through hole is arranged on the limit plate 14. The limit plate 14 is sleeved on the outer surface of the screw rod 12 through the through hole. The limit plate 14 is located between the nut 13 and the side plate 5. Two arc-shaped grooves are symmetrically arranged on the limit plate 14.
[0021] During construction, in order to facilitate the pouring of concrete, formwork needs to be erected first. When erecting formwork, plastic-steel formwork 1, horizontal back ribs 2 and vertical back ribs 3 are used. The horizontal back ribs 2 and vertical back ribs 3 are used to support the plastic-steel formwork 1 to prevent the plastic-steel formwork 1 from deforming due to the impact of concrete and the pressure of concrete on the plastic-steel formwork 1. Connecting holes 4 are provided on all four sides of the plastic-steel formwork 1, and the cross-section of the connecting hole 4 is the same as the cross-section after the circular hole 7 and the extension groove 8 are combined.
[0022] Reference Figure 5 and Figure 6 , before erecting the formwork, first install the plastic-steel formwork 1 on the steel bar framework where the concrete is to be poured. After the plastic-steel formwork 1 is installed on the steel bar framework, place the two extension plates 6 on the same side plate 5 on two plastic-steel formworks 1 respectively, and align the through holes and extension grooves 8 on the extension plates 6 with the connecting holes 4 on the plastic-steel formwork 1. Then insert the pin 9 through the circular hole 7 on the extension plate 6 and through the connecting hole 4 on the plastic-steel formwork 1. The wedge block 10 and the protrusion pass through the extension groove 8 on the extension plate 6 and the connecting hole 4 on the plastic-steel formwork 1. After the pin 9 completely passes through the two extension plates 6, rotate the handle 11. The handle 11 drives the pin 9, the protrusion and the wedge block 10 to rotate 90°. The pin 9, the protrusion and the wedge block 10 are all made of plastic and can deform by themselves. When the rotation of the pin 9 is completed, the protrusion is in close contact with the circular hole 7 on the extension plate 6 and the connecting hole 4 on the plastic-steel formwork 1, thereby connecting two adjacent plastic-steel formworks 1 together.
[0023] The side plate 5 and the extension plate 6 are integrally formed and made of metal. The ends of the two extension plates 6 far from the side plate 5 are movable ends, and the ends of the two extension plates 6 close to the side plate 5 are fixed ends. The distance between the two movable ends is less than the distance between the two fixed ends. Therefore, when the two extension plates 6 are placed on two adjacent plastic-steel formworks 1, the extension plates 6 will deform. Through their own deformation, a certain pressure can be exerted on the plastic-steel formwork 1, thereby pressing and connecting two adjacent plastic-steel formworks 1 together and reducing the gap at the joint between the two.
[0024] After connecting two plastic-steel formworks 1 through the pin 9, there is a certain space between the side plate 5 and the plastic-steel formwork 1 at this time. This space is used for the horizontal back rib 2 to pass through. Pass the horizontal back rib through this space. After installing the horizontal back rib 2, place the two vertical back ribs 3 into the two arc-shaped grooves of the limit plate 14 respectively, and then rotate. During the rotation of the nut 13 on the screw 12, the limit plate 14 will be squeezed. After the limit plate 14 is squeezed, the vertical back rib 3 in the arc-shaped groove will be in contact with the horizontal back rib 2 and continuously squeeze the horizontal back rib 2, so that the horizontal back rib 2 and the vertical back rib 3 are firmly fixed on one side of the plastic-steel formwork 1.
[0025] The existing traditional horizontal back ribs 2 and vertical back ribs 3 are respectively fixed to the periphery of the mold through different reinforcement fittings, and the existing reinforcement fittings can reinforce the horizontal back ribs 2 and the vertical back ribs 3 simultaneously, so that the use of the reinforcement fittings can be reduced and waste can be reduced.
[0026] Further, the protruding part includes two bosses 15, and the two bosses 15 are matched with the round holes 7 on the two extension plates 6. By arranging the two bosses 15, the use of materials can be reduced and the cost can be saved.
[0027] Further, chamfers are arranged at the lower ends of the pin 9 and the wedge block 10, which is convenient for the pin 9 and the wedge block 10 to quickly pass through the round hole 7 and the extension groove 8 on the extension plate 6.
[0028] Further, when the two wedge blocks 10 pass through the extension groove 8 on the extension plate 6, the handle 11 faces the side plate 5, that is, the handle 11 faces away from the plastic-steel formwork 1, which is convenient for rotating the handle 11. After the handle 11 is rotated, the handle 11 is in a parallel state with the plastic-steel formwork 1, and the distance between the handle 11 and the plastic-steel formwork 1 is relatively close, so that the situation of accidentally touching the handle 11 can be reduced. And when the handle 11 is rotated, the wedge block 10 will abut against the round hole 7 on the limit plate 14 to prevent the pin 9 from coming out of the limit plate 14.
[0029] Further, a gasket 16 is arranged between the limit plate 14 and the nut 13.
[0030] This plastic-steel formwork 1 reinforcement fitting can further reinforce the connection between plastic-steel formworks 1 compared with the traditional steel formwork reinforcement method, reduce the gap at the splicing of the plastic-steel formworks 1, reduce the influence of the gap on the concrete after molding, and has a good reinforcement effect.
[0031] In the description of the present invention, unless otherwise clearly defined and limited, the terms "installation", "connection" and "connection" shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.
