[0002] In the existing reverse-cast decorative and heat-insulating integrated board, the surface layer and the structural precast layer are connected by anchor bolts. However, due to the too small root cross-section of the anchor bolts used in the existing technology, stress concentration will occur at the root, and local splitting is likely to occur on the surface layer. In addition, some of the anchor bolts used in the existing reverse-cast decorative and heat-insulating integrated boards adopt steel members, and the anchor bolts without heat-insulating measures will form a penetrating cold bridge, thereby affecting the heat-insulating performance. Summary of the Utility Model

[0003] The utility model first discloses a segmented heat-insulating anchor, which has the effect of blocking the cold bridge, increases the root cross-section to reduce stress concentration, and adopts a segmented structure for connection. The heat-insulating anchor can be used to replace the tie bars in the structural precast layer.

[0007] Further, the nylon splicing section includes a cylinder. A lower flange is formed circumferentially at the bottom of the cylinder. Bolt holes are opened on the lower flange. Grooves are respectively opened on the top of the cylinder along the horizontal and vertical directions. The grooves serve as steel bar buckles. The horizontal groove and the vertical groove penetrate each other. An upper flange is formed on the top of the cylinder outside the horizontal groove and the vertical groove. Bolt holes are opened on the upper flange.

[0008] Furthermore, the cross-sectional shape of the reinforcing fin is a right trapezoid with a narrower upper part and a wider lower part.

[0010] The heat insulation anchor designed by the present utility model uses a heat insulation material to replace the steel used in traditional heat insulation anchor bolts, which can block the cold bridge, and a reinforcing fin rib is arranged circumferentially at the tail of the heat insulation anchor near the decorative panel, which helps to increase the cross-sectional area of the root of the heat insulation anchor and can effectively avoid the splitting phenomenon of the decorative panel caused by stress concentration; moreover, the heat insulation anchor of the present utility model is designed as a segmented splicing structure, which can fix the horizontal and vertical steel bars arranged in the concrete layer structure by using the tail connection section, the splicing section and each layer of splicing section.

[0027] This embodiment first discloses a segmented heat insulation anchor, and its structure is as Figures 1 to 7 shown. The segmented heat insulation anchor 1 is composed of multiple connecting sections assembled with each other. Among them, the bottommost one is the tail connecting section, and only one section of the tail connecting section is provided. The ones above the tail connecting section are all splicing sections, and the structures of each splicing section are the same. The number of splicing sections can be determined according to the thickness of the precast concrete structural layer and the number of steel bar layers arranged inside. In this embodiment and the attached Figure 1 drawings, for example, one splicing section is adopted for introduction. For the convenience 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.

[0028] As Figures 2 to 4As shown, the main structure of the first connecting section 11 is a cylinder 114. A back bolt mounting hole 115 is provided in the bottom surface of the cylinder 114, and threads are provided on the inner wall of the back bolt mounting hole 115. A plurality of (four are provided in the attached drawing) outwardly extending rib plates are circumferentially distributed on the outer wall of the lower part of the cylinder 114. This rib plate is the reinforcing fin 111. The vertical cross-section of the reinforcing fin 111 is a right trapezoid that is narrower at the top and wider at the bottom. After the reinforcing fin 111 is provided, the cross-sectional area of the root of the heat insulation anchor 1 can be increased, and the stress concentration at the root can be reduced. Grooves are respectively provided in the horizontal and vertical directions at the top of the cylinder 114. The grooves serve as steel bar buckles 113. Among them, the horizontal groove and the vertical groove communicate with each other. A flanging 112 is provided at the top of the cylinder. The horizontal groove and the vertical groove divide the flanging 112 into four parts, and bolt holes 116 are provided in the flanging 112.

[0029] As Figures 5 to 7 shown, the main structure of the second connecting section 12 is also a cylinder 121. A downward flanging 124 is formed circumferentially at the bottom of the cylinder 121, and bolt holes 125 are provided in the downward flanging 124. Grooves are also respectively provided in the horizontal and vertical directions at the top of the cylinder 121. The grooves also serve as steel bar buckles 122. The horizontal groove and the vertical groove also communicate with each other. An upward flanging 123 is provided at the top of the cylinder 121. The horizontal groove and the vertical groove divide the upward flanging 123 into four parts, and bolt holes 125 are provided in the upward flanging 123.

[0030] The structure of the heat insulation anchor 1 assembled by the first connecting section 11 and the second connecting section 12 is as Figure 1 shown. The threaded rod of the back bolt 13 is screwed into the back bolt mounting hole 115 at the bottom of the first connecting section 11 for fixation. The downward flanging 124 of the second connecting section 12 is made to fit with the flanging 112 of the first connecting section 11, and a screw 14 is passed through the bolt hole 125 and the bolt hole 116 and then locked and fixed. A fixing pressing plate 15 is covered and fixed on the top of the second connecting section 12. Bolt holes are provided in the fixing pressing plate 15, and a screw 14 is passed through the bolt holes and locked and fixed.

[0031] In this embodiment, when the above-mentioned heat insulation anchor 1 is used in the reverse punching decorative insulation integrated board, the specific structural arrangement is as Figure 8As shown, the reverse-facing decorative and thermal insulation integrated board mainly consists of a decorative panel 2, a thermal insulation material 3, a concrete layer 4, horizontal steel bars 5, vertical steel bars 6, and the above-mentioned segmented heat insulation anchor 1. Among them, back bolt holes are spacedly opened on the back surface (non-decoration outer surface) of the decorative panel 2 first, and then a layer of thermal insulation material 3 is pasted on the back surface of the decorative panel 2 to form an integrated board, and process installation holes are pre-opened on the thermal insulation material 3 to expose each back bolt hole. A segmented heat insulation anchor 1 is provided at each back bolt hole. The heat insulation back bolt 13 can be assembled with the first connection section 11 first and then screwed into the back bolt hole, or the heat insulation back bolt 13 can be first screwed into the back bolt hole, and then the screw rod of the heat insulation back bolt 13 is screwed into the back bolt installation hole 115 at the bottom of the first connection section 11. After the installation of the first connection section 11 is completed, the lowermost horizontal steel bars 5 and vertical steel bars 6 are arranged first, so that the horizontal steel bars 5 pass through the horizontal grooves of the steel bar clamping openings 113 on the first connection section 11, and the vertical steel bars 6 pass through the vertical grooves of the steel bar clamping openings 113 on the first connection section 11. Then the second connection section 12 is assembled and fixed with the first connection section 11, and the second connection section 12 and the first connection section 11 jointly press and fix the lowermost layer of steel bars. Then the steel bar clamping openings 122 on the second connection section 12 are used to position the top layer of steel bars, so that the top horizontal steel bars 5 pass through the horizontal grooves of the steel bar clamping openings 122 on the second connection section 12, and the top vertical steel bars 6 pass through the vertical grooves of the steel bar clamping openings 122 on the second connection section 12. Finally, a fixing washer 15 is covered and fixed on the top of the second connection section 12 and tightened with screws 14, so as to press and fix the top layer of steel bars. After the above assembly is completed, concrete is poured on the upper part of the thermal insulation material 3 to form a concrete layer 4. As Figure 8 shown, the second connection section 12 ties the top layer of steel bars and the bottom layer of steel bars together to form an integral whole, acting as a tie bar, eliminating the need for additional tie bars, which not only reduces costs but also improves the construction assembly speed.
