[0007] As a preferred technical solution, multiple slots are provided on the outer surface of the stretch sheet, and the inner wall of the groove protrudes to form an insert block opposite the slot, and the insert block is inserted into the corresponding slot.

[0008] As a preferred technical solution, a top rod is installed on the top surface of each tension plate, a handle is installed on the bottom surface of each tension plate, and multiple first steel wire ropes are installed inside each tension plate, with the two ends of the first steel wire ropes being fixedly connected to the handle and the top rod respectively.

[0009] As a preferred technical solution, the drive mechanism includes a take-up shaft, a brake motor, multiple positioning plates, and multiple second steel wire ropes. The positioning plates are distributed and installed on the top surfaces of the middle guide rail and the side guide rail. Each positioning plate is provided with an arc-shaped groove. The take-up shaft is placed horizontally in the arc-shaped groove. The take-up shaft has an annular structure recessed at the position opposite the tension plate to form a take-up groove. One end of each second steel wire rope is coiled in the take-up groove, and the other end is installed on the tension plate. Side plates are fixed to the outer surface of each side guide rail by bolts. Sealed bearings are embedded in each side plate. Shafts are installed at both ends of the take-up shaft. The other end of each shaft is installed in the inner ring of the sealed bearing.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0019] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0020] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the present invention discloses a prefabricated building exterior wall structure and energy-saving construction method, comprising multiple energy-saving exterior wall panels 3, multiple intermediate guide rails 1 and side guide rails 2. The intermediate guide rails 1 and side guide rails 2 are vertically and evenly distributed. Channels for the energy-saving exterior wall panels 3 to move up and down are formed between the intermediate guide rails 1 and between the intermediate guide rails 1 and the side guide rails 2. The energy-saving exterior wall panels 3 are slidably installed in the channels. The back of each energy-saving exterior wall panel 3 is provided with a vertical groove 18. Each vertically opposite groove 18 is provided with a tensioning piece 4 that pulls the energy-saving exterior wall panel 3 upward. A driving mechanism for driving the tensioning piece 4 to move upward is installed above the intermediate guide rails 1 and the side guide rails 2. A base plate 6 is provided below the intermediate guide rails 1 and the side guide rails 2.

[0022] In this embodiment, the middle guide rail 1 is arranged in an "I" shape, and the side guide rail 2 is arranged in a "U" shape. A fixing plate 21 is installed inside the middle guide rail 1 and the side guide rail 2. A positioning groove is formed between the fixing plate 21 and the middle guide rail 1 and between the fixing plate 21 and the side guide rail 2. A part of the energy-saving exterior wall panel 3 is reduced inward to form an assembly part 20 that matches the width of the channel. The assembly part 20 extends into the interior of the channel. The other part of the energy-saving exterior wall panel 3 is placed on the outer surface of the middle guide rail 1 or the side guide rail 2, and the part of the energy-saving exterior wall panel 3 located outside the channel is in contact with each other. The bottom surfaces of the middle guide rail and the side guide rail are provided with multiple fixing holes. Screws, expansion bolts and other workpieces can pass through the fixing holes to fix the middle guide rail and the side guide rail to the outer wall to ensure the stability of the side guide rail and the middle guide rail.

[0023] In this embodiment, both sides of the assembly part 20 protrude to form positioning parts 22, and the positioning parts 22 are slidably disposed in the positioning groove. The positioning parts can position the energy-saving exterior wall panel in front and behind, preventing the energy-saving exterior wall panel from falling directly outward from between the channels. In this design, the assembly part of the energy-saving exterior wall panel is installed in the channel, while another part of the energy-saving exterior wall panel is set to the outside. The energy-saving exterior wall panels located on the outside abut against each other, thus completely covering the middle guide rail. The middle guide rail cannot be seen from the outside, ensuring the aesthetics after installation and the tightness of the overall assembly.

[0024] In this embodiment, a plurality of slots 5 are provided on the outer surface of the stretch sheet 4, and the inner wall of the groove 18 protrudes to form a plug 19 opposite to the slot 5, and the plug 19 is inserted into the corresponding slot 5.

[0025] In this embodiment, a top rod 16 is installed on the top surface of each tension plate 4, a handle 8 is installed on the bottom surface of each tension plate 4, and multiple first steel wire ropes 17 are installed inside each tension plate 4. The two ends of the first steel wire ropes 17 are fixedly connected to the handle 8 and the top rod 16, respectively.

[0026] In this embodiment, the drive mechanism includes a take-up shaft 10, a brake motor 15, multiple positioning plates 13, and multiple second steel wire ropes 9. The positioning plates 13 are distributed and installed on the top surfaces of the middle guide rail 1 and the side guide rail 2. Each positioning plate 13 is provided with an arc-shaped groove. The take-up shaft 10 is placed horizontally in the arc-shaped groove. The take-up shaft 10 has an annular structure recessed at the position opposite the tension plate 4 to form a take-up groove 11. One end of each of the second steel wire ropes 9 is coiled in the take-up groove 11, and the other end is installed on the tension plate 4. Side plates 14 are fixed to the outer surface of the side guide rail 2 by bolts. Sealed bearings are embedded in each side plate 14. Both ends of the take-up shaft 10 are installed with shafts, and the other end of each shaft is installed in the inner ring of the sealed bearing. The brake motor 15 is installed on one side plate 14, and the rotating shaft of the brake motor 15 is fixedly connected to the shaft on one side.

[0027] In this embodiment, a plurality of positioning rings 12 are installed in pairs in the middle of the take-up shaft 10. The positioning rings 12 are respectively set on both sides of the positioning plate 13 above the middle guide rail 1. The positioning rings can position the middle guide rails to ensure that the width between the middle guide rails is the same, and also simultaneously complete the lateral positioning of the take-up shaft.

[0028] In this embodiment, both ends of the base plate 6 are bent upward to form a fixing part 7, and each fixing part 7 is provided with a first screw hole, and each side guide rail 2 is provided with a second screw hole on its outer side surface.

[0029] In this embodiment, the tension plates 4 are all made of rubber material, which allows the tension plates to bend in all directions. However, because the tension plates are equipped with a first steel wire rope inside, the tension plates cannot be stretched outwards. The first steel wire rope can provide load-bearing capacity for the tension plates, so that the energy-saving exterior wall panels assembled on the tension plates can be positioned vertically, avoiding the weight being completely applied to the base plate. Furthermore, the energy-saving exterior wall panels can be quickly raised through the tension plates, which facilitates assembly.

[0030] In this embodiment, the construction method is as follows: S1, side guide rail 2 and middle guide rail 1 are all vertically installed on the exterior wall. During the installation process, the positioning plate above the middle guide rail can be inserted between the positioning rings, while the side guide rail is fixed to the side plate by bolts, thereby positioning the middle guide rail and the side guide rail to ensure that the width of the channel between the side guide rail 2 and the middle guide rail 1 and the width of the channel between the middle guide rail 1 are the same. S2. After the above is completed, the stretching plate is vertically set in the middle of the channel. The energy-saving exterior wall panel 3 is first fitted onto the stretching plate 4 through the groove, and the insert 19 on the energy-saving exterior wall panel 3 is inserted into the slot 5. At this time, the brake motor can be started. The start of the brake motor drives the shaft and the winding shaft. The rotation of the winding shaft brings the second steel wire rope. The winding second steel wire rope can pull the stretching plate upward. The upward movement of the stretching plate can automatically drive the energy-saving exterior wall panels one by one into the channel. After the energy-saving exterior wall enters the channel, the positioning part on the energy-saving exterior wall panel can be slidably set in the positioning groove. The sliding connection between the positioning part and the positioning groove ensures the stability of the energy-saving exterior wall panel at the front and back, preventing the energy-saving exterior wall panel from falling out of the channel; Among them, limit blocks are installed at the top of the positioning groove. After all the energy-saving exterior wall panels are put into the channel, the top surface of the top energy-saving exterior wall panel can abut against the limit block to ensure the limit above the row of energy-saving exterior wall panels. S3. After each row of energy-saving exterior wall panels 3 is installed, the base plate 6 can abut against the bottom of the middle guide rail and the side guide rail, while the fixing part extends on the outer side surface of the side guide rail, and the bolts can pass through the first screw hole and the second screw hole to complete the positioning of the bottom of the energy-saving exterior wall panel, so that each row of vertical energy-saving exterior wall panels is in a stable state.

[0031] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
