[0020] S1. Fix the first layer of insulation board to the bottom of the wall with mortar;

[0021] S2. Secure the bracket with expansion bolts through the mounting holes, embedding the support frame into the lower insulation board;

Then the inner anchor is inserted into the interior of the outer anchor, and the round rod and the connecting rod are respectively located inside the conduit and the rectangular tube. At this time, the buckle cover will buckle the insulation board, and then it is rotated so that the limit plate and the rectangular tube are in a cross-shaped state, thereby forming an anti-slip structure. Moreover, since the rubber pad and the insulation board themselves have a certain elasticity, the inner anchor can rebound outward for a distance after being inserted, installed and rotated, so that the side wall of the side hole is inserted into the interior of the limit groove to prevent it from rotating.

[0031] The present invention uses a combined structure of brackets. The L-shaped structure of the mounting frame can simultaneously support the upper insulation board and clamp the lower insulation board. The U-shaped structure of the support frame forms an inward buckle anti-slip structure. In combination with the splicing design of the embedded surface and the fitting surface, adjacent brackets form a continuous support system, which can further increase the firmness.

[0032] The present invention uses the anti-detachment structure of the anchor bolt and the rotational engagement of the inner anchor and the outer anchor to further prevent the inner anchor from detaching from the insulation board after installation on the wall. Combined with the elastic reset function of the rubber pad, the edge of the side hole automatically fits into the limit groove, forming a physical anti-rotation structure.

[0033] When in use, the present invention realizes the fixation of the bracket and the anchor bolt through a modular installation process, and can have an inward-buckled structure on the basis of the original support, thereby effectively increasing the stability of its installation and reducing the probability of the insulation board falling off easily due to insufficient support due to excessive thickness. The invention effectively improves the anti-falling ability of the insulation board and is suitable for the construction of thick insulation layers in ultra-low energy consumption buildings.

[0042] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0043] Example 1

[0044] from Figure 1-2 As can be seen, the enclosure structure anchor bracket assembly of this embodiment includes a bracket 1, an anchor 2 and an insulation board 3. The bracket 1 includes a mounting frame 11 and a support frame 12 connected to each other. The bracket 1 is formed by bending the mounting frame 11 and the support frame 12 into one piece. The mounting frame 11 and the support frame 12 are formed by bending galvanized steel plates into one piece or by stamping two plates and then welding them together.

[0045] The mounting frame 11 is an L-shaped structure, comprising a first vertical plate 111 that is attached to the wall and a first horizontal plate 112 that extends horizontally. The first horizontal plate 112 is used to support the upper insulation board 3 and clamp the lower insulation board 3;

[0046] Mounting holes 13 are provided at both ends of the first vertical plate 111. The first vertical plate 111 is attached to the wall surface as a mounting plate, and mounting holes 13 for installing expansion bolts are provided at both ends of the surface.

[0047] The support frame 12 is a U-shaped structure, comprising two second vertical plates 121 and a second horizontal plate 122 for connecting the second vertical plates 121. The second vertical plates 121 are provided with insertion holes 15 on their surfaces for receiving anchor bolts 2. The support frame 12 is used to support the upper insulation board 3 and form an inward buckle structure, as well as to clamp the lower insulation board 3 and form an inward buckle mechanism.

[0048] An inlay surface 14 is provided on the back of the bracket 1 , and a fitting surface 16 is provided on one end of the bracket 1 . Adjacent brackets 1 in the same row are seamlessly spliced ​​together through the inlay surface 14 and the fitting surface 16 .

[0049] from Figure 3-5 It can be seen that the anchor bolt 2 includes an inner anchor 21 and an outer anchor 22 sleeved thereon;

[0050] The external anchor 22 includes a conduit 221 that passes through the insulation board 3 and the insertion hole 15 and a rectangular tube 222 that is anchored to the wall;

[0051] The inner anchor 21 includes a round rod 212 inserted into the conduit 221, a connecting rod 213 for connecting the round rod 212, and a buckle cover 211 for pressing the insulation board 3;

[0052] A limiting plate 214 is provided on the connecting rod 213 , and the inner anchor 21 is rotated so that the limiting plate 214 and the rectangular tube 222 are cross-intersected to form an anti-slip structure.

[0053] The outer anchor 22 includes a conduit 221 and a rectangular tube 222. By passing it through the holes on the insulation layer 3 and the bracket 1, it can be nailed into the hole in the wall to achieve a preliminary connection. After that, the inner anchor 21 is inserted and the insulation board 3 is buckled to the wall surface through the buckle cover 211.

[0054] A side hole 223 is formed on the outer wall of the rectangular tube 222 , and a limiting groove 215 is formed on the side wall of the limiting plate 214 . After the inner anchor 21 is rotated, the edge of the side hole 223 is locked into the limiting groove 215 .

[0055] A rubber pad is provided on the inner side of the buckle cover 211 , which deforms under pressure to drive the side hole 223 to fit into the limiting groove 215 .

[0056] A side hole 223 is provided on the outer wall of the rectangular tube 222. The inner anchor 21 is inserted into the interior of the outer anchor 22, and the round rod 212 and the connecting rod 213 are respectively located inside the conduit 221 and the rectangular tube 222. At this time, the buckle cover 211 will buckle the insulation board 3. At this time, it is rotated again to make the limit plate 214 rotate to the inside of the insulation board 3, so that the limit plate 214 and the rectangular tube 222 are in a cross-shaped state, thereby forming an anti-slip structure. Moreover, since the side wall of the limit plate 214 is provided with a limit groove 215, when the inner anchor rebounds outward through the rubber pad and the insulation board 3, the side wall of the side hole 223 is inserted into the inside of the limit groove 215 to prevent it from rotating.

[0057] Example 2

[0058] from Figure 6-7 It can be seen that the method for fixing the outer insulation board of a housing structure anchor bracket assembly of this embodiment comprises the following steps:

[0059] S1. The first layer of insulation board 3 is fixed to the bottom of the wall by mortar;

[0060] S2. Fix the bracket 1 with expansion bolts through the mounting holes 13, and the support frame 12 is embedded in the lower insulation board 3;

[0061] S3. Fix the second layer of insulation board 3 above the bracket 1;

[0062] S4. The outer anchor 22 passes through the insulation board 3 and the jack 15, the end of the rectangular tube 222 is nailed into the preset hole in the wall, anchoring the rectangular tube 222 to the wall;

[0063] S5. Insert the inner anchor 21 and rotate 90 degrees so that the limit plate 214 crosses the rectangular tube 222. At this time, the rubber pad is compressed and deformed so that the edge of the side hole 223 is stuck into the limit groove 215;

[0064] S6. Repeat S1-S5 to complete the installation of multi-layer insulation panels 3 alternately;

[0065] After the brackets 1 in the same row are installed, the embedded surface 14 is spliced ​​with the fitting surface 16, and the mounting holes 13 and the insertion holes 15 are aligned with the mounting holes 13 and the insertion holes 15 of the adjacent brackets 1. After the components in the same row are installed, the anchor bolts 2 are fixed uniformly.

[0066] The top and bottom shapes of the insulation board 3 match the outline of the bracket 1, and the top and bottom insulation boards 3 are cut and formed from the whole board, thereby reducing waste.

[0067] In the present application, during specific use, the outer anchor 22 is passed through the insulation board 3 and the socket 15, and the end of the rectangular tube 222 is nailed to the preset hole in the wall, and then the inner anchor 21 is inserted into the interior of the outer anchor 22, and the round rod 212 and the connecting rod 213 are respectively located inside the conduit 221 and the rectangular tube 222. At this time, the buckle cover 211 will buckle the insulation board 3, and then it is rotated so that the limit plate 214 and the rectangular tube 222 are in a cross-shaped state, thereby forming an anti-slip structure. Moreover, since the rubber pad and the insulation board 3 themselves have a certain elasticity, the inner anchor 21 can rebound outward for a distance after being inserted, installed and rotated, so that the side wall of the side hole 223 is inserted into the inside of the limit groove 215 to prevent it from rotating.

[0068] In the present invention, through the combined structure of the bracket 1, the L-shaped structure of the mounting frame 11 can simultaneously support the upper insulation board 3 and clamp the lower insulation board 3. The U-shaped structure of the support frame 12 forms an inward buckle anti-slip structure, and the splicing design of the embedded surface 14 and the fitting surface 16 is combined to form a continuous support system for adjacent brackets 1, which can further increase the firmness.

[0069] In the present invention, the anti-slip structure of the anchor bolt 2 can achieve the effect of the rotational engagement between the inner anchor 21 and the outer anchor 22, so that after being installed on the wall, the inner anchor 21 is further prevented from being separated from the insulation board 3. In combination with the elastic reset function of the rubber pad, the edge of the side hole 223 is automatically embedded in the limit groove 215, forming a physical anti-rotation structure.

[0070] When in use, the present invention realizes the fixation of the bracket 1 and the anchor bolt 2 through a modular installation process, and can have an inward-buckled structure on the basis of the original support, thereby effectively increasing the stability of its installation and reducing the probability of the insulation board 3 falling off easily due to insufficient support due to excessive thickness. The invention effectively improves the anti-falling ability of the insulation board and is suitable for the construction of thick insulation layers in ultra-low energy consumption buildings.

[0071] The above is a schematic description of the present invention and its embodiments, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by this and, without departing from the purpose of the present invention, designs a structure and embodiment similar to this technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
