The front cover plate 11 is provided with a plurality of mounting hole groups from top to bottom, and each mounting hole group includes two mounting holes 14 arranged on the left and right.

[0037] The rear cover assembly 2 is as follows Figure 5 As shown, it includes a rear cover plate 21, and the left and right ends of the front of the rear cover plate 21 are bent to form a rear cover plate side plate 22, and the front side of the rear cover plate side plate 22 is provided with an outer snap folding edge 23, and the rear cover plate side plate 22 is located on the inner side of the corresponding front cover plate side plate 12, and the outer snap folding edge 23 is hooked on the corresponding inner snap folding edge 13, as shown in FIG. Figure 7 shown.

[0038] Several anchor steel bar components 3 such as Figure 2 As shown, corresponding to the plurality of mounting hole groups installed on the front cover assembly 1.

[0039] Each anchor steel bar component 3 is as follows Figure 6 As shown, it includes a U-shaped anchoring steel bar 31. The steel bars on both sides of the U-shaped anchoring steel bar 31 face the rear cover plate 21 and are passed through the left and right mounting holes 14 to the inside of the cavity formed by the front cover plate assembly 1 and the rear cover plate assembly 2. The ends of the steel bars on both sides of the U-shaped anchoring steel bar 31 are bent with connecting steel bars 32. The two connecting steel bars 32 are in an inverted eight-shaped structure. The connecting steel bars 32 of several anchoring steel bar assemblies 3 are staggered and fixed with each other up and down, without the need for additional cross bars for fixing, and the binding method is more stable.

[0040] A plurality of convex points are evenly distributed on the surface of the front cover plate 11 and the rear cover plate 21. The convex point pattern can increase the anchoring force.

[0041] The thickness of the front cover plate 11, the front cover plate side plate 12 and the inner buckle folding edge 13 are all 0.5 mm. The front cover plate 11, the front cover plate side plate 12 and the inner buckle folding edge 13 are formed by bending the iron sheet in one piece.

[0042] The thickness of the rear cover plate 21, the rear cover plate side plate 22 and the outer buckle folding edge 23 are all 0.5 mm. The rear cover plate 21, the rear cover plate side plate 22 and the outer buckle folding edge 23 are made of iron sheet by integral bending.

[0043] The front cover assembly 1 and the rear cover assembly 2 are installed by means of snap-fits, which makes the connection more secure and convenient to install and disassemble.

[0044] The distance between the front of the front cover plate 11 and the back of the rear cover plate 21 is 50 mm. The overall thickness of the device is 50 mm, and the interior does not need to be filled with extruded board.

[0045] There are five groups of mounting holes on the front cover plate 11 .

[0046] In the application of large steel formwork concrete structures, due to the construction process, some shear walls will be cast in a certain order. The shaping device of the utility model is processed with a 0.5mm thick thin iron sheet, and the front cover plate assembly 1 and the rear cover plate assembly 2 are bent into a buckle type, and a hole one size larger than the anchor steel bar assembly 3 is punched on the surface of the front cover plate 11. According to the steel bar specifications and models required in the design and construction drawings, the steel bar anchoring, lap length, and steel bar spacing required by the specifications, the shaping anchor steel bar assembly 3 is processed. The formed anchor steel bar assembly 3 is inserted into the front cover plate 11 with holes, and the anchoring end is placed on the outside of the front cover plate 11. After the connecting steel bar 32 is arranged, tied, and installed firmly, the rear cover plate 21 is installed through the buckle slot. According to the requirements of the design drawings, the shaping device is fixed at the designed position, the anchor steel bar assembly 3 is anchored to the inside of the shear wall constructed first, and the rear cover plate 21 is close to the surface of the formwork. The shaping device is fixed firmly, and concrete slurry is prevented from entering the device. After the concrete pouring is completed, the rear cover plate 21 of the device is removed, the connecting steel bars 32 in the device are straightened, and tied or welded firmly with the horizontal steel bars of the shear wall to complete the steel bar connection.

[0047] The steps of using the utility model on site are:

[0048] The first step: processing and production of finalized equipment:

[0049] In the material processing plant, 0.5mm thick thin iron sheets are cut into fixed sizes according to the dimensions required by the design and processing drawings. According to the in-depth design of the punching diameter and the longitudinal and transverse spacing of the steel bars, the punching positions are drawn on the iron sheet, and the steel bar positions are punched out on the punching machine. According to the shape shown in the design diagram, the front cover assembly 1 and the rear cover assembly 2 are folded into snap-on type on the folding machine. According to the steel bar specifications and specifications of the design drawings, the anchor steel bar assembly 3 is cut and processed. After the anchor steel bar assembly 3 is processed, the U-shaped anchor steel bar 31 of the anchor steel bar assembly 3 is installed on the front cover 11 to expose the connecting steel bar 32, and the connecting steel bar 32 is bent and tied to the inner side of the box body of the front cover 11, and the rear cover 21 is fixed through the snap-on groove.

[0050] Step 2: Install the finalization device:

[0051] According to the design drawing position, first install the template on one side of the standardized device, and fix it firmly with the main reinforcement of the shear wall. After the standardized device and the main reinforcement of the shear wall are fixed according to the design drawing position, set the vertical additional reinforcement at the rear anchor reinforcement position, and the horizontal reinforcement on the outside of the shear wall passes through the inside of the additional reinforcement and is firmly tied with the additional reinforcement. On the side of the standardized device, set the additional reinforcement. The spacing between the reinforcements is the same as that of the shear wall. It is firmly tied with the horizontal reinforcement of the shear wall on one side of the standardized device. The length of the horizontal lap section meets the requirements of the specification. Figure 8 shown.

[0052] Step 3: Install shear wall formwork:

[0053] Then install the template on the other side of the finalization device and fix it firmly to the main reinforcement of the shear wall. Fix the connecting device to the template surface to avoid disturbance during the concrete pouring process. Fig. 9 shown.

[0054] Step 4: pouring concrete and removing formwork:

[0055] During the pouring of concrete, the vibrator should not directly contact the shaping device. It is sufficient to meet the vibration range and maintain a certain distance. After the formwork is removed, clean the formwork in time. Fig.10 , Fig.11 shown.

[0056] Step 5: Straighten and connect the steel bars 32. Tie and connect the steel bars:

[0057] Remove the rear cover plate 21 of the shaping device, and straighten the connecting steel bars 32 inside the shaping device. Fig.12 As shown, under the premise of meeting the design and specifications, the steel bars are connected by tying overlap or welding.

[0058] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the utility model, or are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
