[0020] The surface of the concrete shear wall column 1 is fixed with a support plate 14 by expansion screws, and the surface of the support plate 14 contacts the prefabricated lintel 3. In order to provide support for the prefabricated lintel 3 through the support plate 14, the prefabricated lintel 3 is placed on the side wall of the concrete shear wall column 1.
[0021] A steel cage 12 is laid inside the prefabricated lintel 3 and inside the concrete shear wall column 1, and the first spliced steel bars 13 and the second spliced steel bars 31 are connected to the steel cage 12 to increase the stability and firmness between the spliced steel bars and the prefabricated lintel 3 and the concrete shear wall column 1.
[0022] Both ends of the prefabricated lintel 3 are provided with connecting grooves 33, and rubber pads 34 are engaged inside the connecting grooves 33. The rubber pads 34 are installed at the connection between the prefabricated lintel 3 and the concrete shear wall column 1, and at the connection between the prefabricated lintel 3 and the block wall 4.

[0025] One end of the first spliced steel bar 13, the second spliced steel bar 31, one end of the compression plate 81, both ends of the first fixed steel bar 5, and both ends of the second fixed steel bar 6 are all hook-shaped to facilitate the direct connection of the steel bars to each other; the diameter of the first fixed steel bar 5 is greater than the diameter of the second fixed steel bar 6 to facilitate the second spliced steel bar 31 to pull the second fixed steel bar 6 toward the concrete shear wall column 1.
[0026] The working principle of the formwork system for lintel construction provided by the present invention is as follows: when performing lintel construction, the support plate 14 and the first spliced steel bar 13 are installed on the surface of the concrete shear wall column 1, the height of the block wall 4 is flush with the surface of the support plate 14, one end of the second spliced steel bar 31 inside the prefabricated lintel 3 is bent, and the rubber pad 34 is engaged inside the connecting groove 33; then the prefabricated lintel 3 is placed on the surface of the support plate 14 and the block wall 4, and then the position of the prefabricated lintel 3 is aligned. The first spliced steel bar 13 and the second spliced steel bar 31 are connected through the first fixed steel bar 5. In the vertical direction, the hooks 71 are hooked on the surfaces of the two first fixed steel bars 5 respectively, and the screw rod 73 is rotated. The screw rod 73 rotates and moves forward inside the screw sleeve 74, and the screw rod 73 moves inside the fixed sleeve 75. The screw rod 73 pushes the distance between the fixed sleeve 75 and the screw sleeve 73 to become larger and larger, driving the fixed sleeve 75 and the support rod 72 on the side wall of the screw sleeve 74 to rotate, thereby driving the distance between the two hooks 71 to become closer and closer. The hooks push the two first fixed steel bars 5 to approach each other, so that the two ends of the first fixed steel bar 5 pull the first spliced steel bar 13 and the second spliced steel bar 31 respectively, so that the first fixed steel bar 5 tilts upward to pull the prefabricated lintel 3, thereby driving the prefabricated lintel 3 to move toward the direction of the concrete shear wall column 1, and the rubber pad 34 is squeezed between the two to improve the sealing of the connection between the two, prevent leakage and fix the position of the prefabricated lintel 3 (as shown in the attached figure). Figure 6As shown). Continue to stack blocks alternately on the surface of the block wall 3, and place the block embedding bars 43 on the surface of each block for each layer. On the surface of the wall, extend some blocks into the interior of the groove 32, and place the third splicing steel bar 42 on one side of the block. When the height of the block wall 4 is higher than the height of the prefabricated lintel 3, stop wall construction. The block wall 4 and the concrete shear wall column 1 respectively close the two ends of the prefabricated lintel 3, and use the second fixed steel bar 6 to connect the third splicing steel bar 42 with the second splicing steel bar 31, hook one end of the compression plate 81 on the second fixed steel bar 6, and the compression plate 81 and the two compression plates 81 are close to each other. The compression plate 81 pulls the second fixed steel bar 6 to make it stretched, and then the bolt 83 is used to penetrate the slide groove 82 to fix the two compression plates 81 and the second fixed steel bar 6. Continue to rotate the screw rod 73, the tension of the first fixed steel bar 5 on the second spliced steel bar 31 increases, so that the second spliced steel bar 31 pulls the second fixed steel bar 6 toward the direction of the concrete shear wall column 1, so that the second fixed steel bar 6, the third spliced steel bar 42 and the block embedded steel bar 43 pull the prefabricated lintel 3 upward obliquely, and then fix the prefabricated lintel 3 (as shown in the attached figure). Figure 1 and attached Figure 6 As shown). Pour mortar into the groove 32, the mortar covers the steel bars, and after the mortar solidifies, the prefabricated lintel 3, the concrete shear wall column 1 and the block wall 4 are connected together. During the construction process, the prefabricated lintel 3, the concrete shear wall column 1 and the block wall 4 are combined to form a lintel construction template system, and there is no need to support wooden modules separately, thereby speeding up the construction efficiency. At the same time, the first fixed steel bar 5, the second fixed steel bar 6 and the second spliced steel bar 31 inclinedly arranged inside the prefabricated lintel 3 are in a pulled state, and prestress is applied to the steel bars inside the prefabricated lintel 3 in advance, so that the steel bars pull the prefabricated lintel 3 upward, thereby improving the stability, firmness and shear resistance of the connection between the prefabricated lintel 3 and the concrete shear wall column 1 and the block wall 4. When the mortar is poured inside the groove 32, the mortar contacts the connecting block 41 with an uneven surface inside the groove 32, thereby increasing the firmness of the connection between the connecting block 41 and the mortar, and a part of the connecting block 41 is fixed in the solidified mortar, and the other part is fixed inside the block wall 4, thereby increasing the stability and firmness of the connection between the prefabricated lintel 3 and the block wall 4, avoiding looseness between the two, and reducing the probability of a gap between the two.
