[0002] In the prior art, the surface layer and the prefabricated structural layer are connected by anchor bolts. However, the anchor bolts used in the prior art have too small a root cross-section, which will lead to stress concentration at the root and make the surface layer prone to local splitting. In addition, the anchor bolts used in some prior art reverse-beat decorative thermal insulation integrated panels are made of steel components. The anchor bolts have no thermal insulation measures and will form a penetrating cold bridge, which will affect the thermal insulation performance. When pouring concrete in the reverse-beat structure, tie bars need to be set inside the structural layer to connect the steel bars together. The additional setting of tie bars will increase the manufacturing cost and add additional construction steps. Summary of the invention

The cross-section of the rib reinforcement tail wing is a right-angled trapezoid that is narrow at the top and wide at the bottom. A flange with a bolt hole is formed on the top edge of the cylinder. Grooves that are interconnected are provided in the horizontal and vertical directions on the top of the cylinder as steel bar bayonet. The nylon splicing section includes a cylinder. A lower flange is formed circumferentially on the bottom edge of the cylinder. The top edge forms an upper flange, and grooves that penetrate each other are respectively provided in the horizontal and vertical directions on the top of the cylinder as steel bar snap-ons, and bolt holes are provided on the lower flange and the upper flange; the lower flange of the nylon splicing section is attached to the flange of the nylon tail connecting section and fixed with screws, and a fixing pressing plate with a threaded hole is provided on the top of the uppermost nylon splicing section, and the fixing pressing plate is installed on the upper flange with screws, and the transverse steel bars and vertical steel bars of the bottom layer inside the concrete layer respectively pass through the transverse grooves and vertical grooves of the nylon tail connecting section, and the transverse steel bars and vertical steel bars of the remaining layers inside the concrete layer respectively pass through the transverse grooves and vertical grooves of the nylon splicing section of the corresponding layers.
[0005] The present invention also discloses a method for constructing the above-mentioned back-punched decorative thermal insulation integrated panel without tie bars, which specifically comprises the following steps: Step 1) Open a back bolt hole on the back of the decorative panel and install a thermal insulation back bolt in the back bolt hole; Step 2) bonding the thermal insulation material to the back of the decorative panel, and opening a process installation hole on the thermal insulation material to expose the back bolt; Step 3) The bottom of the nylon tail connecting section in the segmented thermal break anchor is fixedly connected to the thermal break back bolt; Step 4) Arrange the bottom layer of steel bars, pass the bottom layer of transverse steel bars through the transverse grooves of the nylon tail connecting section, and pass the bottom layer of vertical steel bars through the vertical grooves of the nylon tail connecting section; Step 5) fixedly connecting the bottom of the nylon splicing section adjacent to the nylon tail connecting section in the segmented thermal insulation anchor to the top of the nylon tail connecting section; Step 6) Arrange the second bottom layer of steel bars, pass the transverse steel bars of the second bottom layer through the transverse grooves of the nylon splicing section of the corresponding layer, pass the vertical steel bars of the second bottom layer through the vertical grooves of the nylon splicing section of the corresponding layer, and then arrange a fixed pressing plate on the top of the nylon splicing section, and fix the fixed pressing plate to the top of the nylon splicing section; Step 7) For the setting of more than two layers of steel bars, repeat the above step 6) to complete the fixing of other layers of steel bars, and then pour concrete on the top of the insulation material to cover each layer of steel bars and the segmented thermal insulation anchors.

The number of splicing sections can be determined according to the thickness of the precast concrete structure layer and the number of steel bars arranged inside. Figure 1 In the description, a splicing section is used as an example. For the sake of distinction, in this embodiment, the tail connecting section is called the first connecting section 11, and the splicing section is called the second connecting section 12. The first connecting section 11 and the second connecting section 12 are spliced and fixed.

The vertical section of the rib reinforcement tail 111 is a right-angled trapezoid with a narrow top and a wide bottom. After the rib reinforcement tail 111 is provided, the cross-sectional area of the root of the thermal insulation anchor 1 can be increased and the stress concentration at the root can be reduced. Grooves are provided in the horizontal and vertical directions on the top of the cylinder 114, respectively, and the grooves serve as steel bar clips 113, wherein the horizontal grooves and the vertical grooves are mutually connected, and a flange 112 is provided on the top of the cylinder 114, and the horizontal grooves and the vertical grooves divide the flange 112 into four parts, and a bolt hole 116 is provided on the flange 112.
[0012] like Figures 5 to 7As shown, the main structure of the second connecting section 12 is also a cylinder 121, and a lower flange 124 is formed circumferentially at the bottom of the cylinder 121. Bolt holes 125 are provided on the lower flange 124. Grooves are also provided in the transverse and vertical directions on the top of the cylinder 121, and the grooves also serve as steel bar clips 122. The transverse grooves and the vertical grooves are also interconnected. An upper flange 123 is provided on the top of the cylinder 121. The transverse grooves and the vertical grooves divide the upper flange 123 into four parts, and bolt holes 125 are provided on the upper flange 123.
[0013] The structure of the thermal break anchor 1 assembled from the first connecting section 11 and the second connecting section 12 is as follows: Figure 1 As shown, the threaded rod of the thermal insulation back bolt 13 is screwed into the back bolt installation hole 115 at the bottom of the first connecting section 11 to fix it, so that the lower flange 124 of the second connecting section 12 fits with the flange 112 of the first connecting section 11, and the screw 14 is passed through the bolt hole 125 and the bolt hole 116 and then locked and fixed. The top of the second connecting section 12 is covered with a fixed pressing plate 15, and a bolt hole is opened on the fixed pressing plate 15, and the screw 14 is passed through the bolt hole to lock and fix it.
[0014] This embodiment also discloses a reverse-beating construction method of the above-mentioned reverse-beating decorative thermal insulation integrated panel without tie bars, as shown in FIG. 9 (a) to FIG. 9 (g). The entire construction process is described as follows in conjunction with the corresponding drawings: Step 1) As shown in FIG. 9 (a), back bolt holes are firstly provided at intervals on the back side of the decorative panel 2, and the thermal insulation back bolts 13 are installed in the back bolt holes; Step 2) As shown in FIG. 9 (b), the thermal insulation material 3 is then bonded to the back of the decorative panel 2, and then a process installation hole 7 is opened on the thermal insulation material 3 to expose the thermal insulation back bolt 13; Step 3) As shown in FIG. 9 (c), the first connecting section 11 is first fixedly connected to the thermal break back bolt 13, and the screw of the thermal break back bolt 13 is screwed into the back bolt mounting hole 115 at the bottom of the first connecting section 11; Step 4) As shown in FIG. 9 (d), the bottom layer of transverse reinforcement 5 and vertical reinforcement 6 are arranged, and the bottom layer of transverse reinforcement 5 is respectively passed through the transverse grooves of the adjacent first connecting sections 11, and the bottom layer of vertical reinforcement 6 is respectively passed through the vertical grooves of the adjacent first connecting sections 11; Step 5) As shown in FIG. 9 (e), the second connecting section 12 is fixedly connected to the first connecting section 11, that is, the lower flange 124 of the second connecting section 12 is abutted against the flange 112 of the first connecting section 11 and the two are fixed with screws 14; Step 6) As shown in FIG9 (f), taking two layers of steel bars as an example, this step is to set and fix the top layer of steel bars.
