[0021] Embodiment 1:
[0022] like Figures 1 to 3 A wet joint waterproofing and anti-leakage device for a composite plate includes a reinforcing rod 10, a connecting nut 20 and a lower screw rod 30.
[0023] The reinforcement rod 10 is provided with a cross bar 11, a vertical bar 12 and a cross bar 15, and the cross bar 11, the vertical bar 12 and the cross bar 15 are all made of 18mm steel bars. The vertical bar 12 is arranged in the middle of the cross bar 11, and the vertical bar 12 is vertically welded to the cross bar 11, and the cross bar and the vertical bar form a "T"-shaped structure. A cross bar 15 is respectively arranged at both ends of the cross bar 11, and the cross bar 15 is vertically welded to the cross bar 11, and the direction of the cross bar is also perpendicular to the vertical bar 12, and the cross bar and the cross bar form an "H"-shaped structure.
[0024] A water stop plate 13 is provided at the lower end of the vertical pole 12. The water stop plate 13 is a steel plate with a thickness of 3 mm. In this embodiment, the water stop plate is a square steel plate with a side length of 50 mm. In order to obtain a good water blocking effect, the side length of the square water stop plate should not be less than 50 mm. The water stop plate 13 is welded to the vertical pole 12 in the center, and the plate surface of the water stop plate 13 is perpendicular to the vertical pole 12.
[0025] A reinforcing screw 14 is provided at the lower end of the water stop plate 13 . The reinforcing screw 14 is an M12 screw. The reinforcing screw 14 is welded to the lower end of the water stop plate and is coaxial with the vertical rod 12 .
[0026] The reinforcing screw rod 14 is connected to a connecting nut 20 , and the connecting nut 20 is provided with an M12 screw hole that matches the thread of the reinforcing screw rod.
[0027] The connecting nut is connected to a lower screw rod 30 , which is an M12 long screw rod and is threadedly connected to the connecting nut 20 .
[0028] The connecting nut 20 is a nut with a conical outer circle. The small diameter end of the connecting nut is connected to the reinforcing screw rod 14 , and the large diameter section of the connecting nut is connected to the lower screw rod 30 .
[0029] A reinforcing plate 51 and a mounting nut 52 are provided on the screw rod 30 .
[0030] like Figure 3 As shown, in this embodiment, the lower template 41 is a wooden template. A wet joint 42 is provided between two superimposed boards 43, and a through hole 44 is provided in the middle of the wet joint 42 of the lower template.
[0031] like Figure 3As shown, when in use, first assemble the reinforcing rod 10, the connecting nut 20 and the lower screw 30 together. The two ends of the connecting nut 20 are respectively connected to the reinforcing screw 14 and the lower screw 30 of the reinforcing rod, so that the ends of the reinforcing screw 14 and the lower screw 30 can be pressed against each other, so that the reinforcing rod and the lower screw remain in a fixed state. During assembly, the distance S from the lower end of the connecting nut 20 to the lower edge of the cross bar 11 should be equal to the thickness of the laminated plate. By adjusting the length of the reinforcing screw 14 screwed into the connecting nut 20, the distance from the lower end of the connecting nut 20 to the lower edge of the cross bar 11 can be adjusted.
[0032] Then, the vertical rod 12 passes through the wet joint area 42, and the lower screw rod 30 passes through the through hole 44 of the lower template, so that the cross bar 11 and the cross bar 15 are placed on the top of the composite board, and the lower end of the connecting nut 20 corresponds to the bottom surface of the composite board, and the lower screw rod 30 passes through the lower template downward, as shown in FIG. Figure 4 shown.
[0033] Under the bottom template, insert the reinforcing plate 51 into the lower screw rod 30, and use the mounting nut 52 to lock the reinforcing plate 51, so that the bottom template 41 is tightly fitted with the superimposed plate 43 and the connecting nut 20. Figure 5 In order to reduce the gap between the bottom template and the laminated board, a sealing strip 60 is provided between the bottom template and the laminated board, and the sealing strip is a single-sided foam tape.
[0034] Then, the concrete can be cast in situ, and the cast in situ concrete 44 covers the composite plate 43 and the reinforcement rod 10, the connection nut 20, and fills the wet joint 42 area. Figure 6 shown.
[0035] After the cast-in-place concrete has initially set, the mounting nut 52, the reinforcing plate 51 and the lower screw rod 30 can be removed, and the reinforcing rod 10 and the connecting nut 20 remain in the concrete.
[0036] The connecting nut 20 with a conical outer circle is adopted, and the large diameter end of the connecting nut contacts the bottom template, which can improve the effect of preventing leakage. The large diameter end of the connecting nut is connected to the reinforcing screw rod, so that the pouring concrete can be well filled between the connecting nut and the reinforcing pole.
[0037] The utility model adopts a water stop plate arranged on the vertical pole, which can prevent water from flowing along the gap between the vertical pole and the poured concrete, and effectively prevent the problem of water seepage in the gap between the vertical pole and the poured concrete. The horizontal bars are arranged at both ends of the horizontal bar, which can reduce the contact stress between the reinforcement component and the composite board, improve the installation stability, and avoid damage to the composite board. When a wooden bottom template is used, a support frame (scaffolding) will be used to support the bottom template. Wooden beams and supporting steel pipes are arranged between the bottom template and the support frame. At this time, the mountain-shaped card can only be fixed with the supporting steel pipe, which limits the opening position of the bottom template and is not convenient for the assembly of the bottom template. The utility model adopts a reinforcement plate to replace the mountain-shaped card. The reinforcement plate can adopt a template (wooden block), a fixing structure of the reinforcement plate and the mounting nut, which avoids the installation limitations of the mountain-shaped card, can facilitate construction and installation, and improve construction quality.
[0038] Embodiment 2:
[0039] like Figure 7 , a wet joint water-stopping and anti-leakage device for composite plates, this embodiment is a structural replacement of the first embodiment.
[0040] In this embodiment, the water stop plate 13 is a circular steel plate with a diameter of not less than 50 mm. The use of a circular water stop plate can achieve the same water stop function.
