Description

Technical Field

[0001] This invention belongs to the technical field of external wall insulation, and in particular relates to a building insulation board anchor and its external wall insulation system. Background Technology

[0002] Insulation board anchors are widely used to firmly fix the insulation board to the wall structure. They are mainly used in precast concrete reverse-flow insulation systems or cast-in-place concrete composite insulation systems to fix the insulation board to the wall structure. This prevents the insulation board from separating from the wall structure and falling off under extreme conditions, thus ensuring the safety of the building's external wall insulation system.

[0003] Currently, insulation board anchors typically use nylon plastic to make the anchor rods and end plates. The anchor rods pass through the insulation board, and the end plates connect to the wall structure. A further improvement involves making the anchor rods into hollow tubes with expanded ends. After the hollow plastic tubes pass through the insulation board, anchor nails are inserted inside the tubes. The anchor nails extend to the end of the anchor rods, causing them to expand and thus firmly anchor to the wall structure.

[0004] Several problems exist with existing insulation board anchors: Firstly, the plastic end plate provides insufficient bonding strength to the insulation board. During tensile tests, the end plate deforms significantly, causing it to fail to reach its design tensile strength before it can function properly, especially in high-rise buildings. Secondly, the hollow tubes, typically made of plastic, deform considerably and cannot effectively secure the insulation board to the structural surface. In extreme cases, the insulation board may detach from the concrete, leading to safety hazards such as board detachment under horizontal loads. Thirdly, the plastic ends expand, and the metal is not directly connected to the wall structure, resulting in insufficient tensile strength. Finally, metal nails penetrating the hollow tube into the wall structure pose risks such as water seepage. Summary of the Invention

[0024] The insulation board 15 is placed on the upper and lower surfaces of the main board 1, and can be a vacuum insulation board or a conventional insulation material board. The wall 14 is detachably connected to the first fixing plate 2 and the second fixing plate 3 through mounting holes; the outer wall 17 is detachably connected to the connector through mounting holes.

[0025] The building insulation board anchor specifically includes a main board 1, a first fixing plate 2, a second fixing plate 3, a first bending plate 4, a second bending plate 5, a connecting plate 6, a connector, a bending portion 20, and a first mounting hole 11. The main board 1 is a flat plate, with the first fixing plate 2 and the second fixing plate 3 integrally connected to one end of the flat plate, and the first bending plate 4, the second bending plate 5, and the connecting plate 6 integrally connected to the other end. The first fixing plate 2 and the second fixing plate 3 are placed adjacent to each other and are detachably fixed to the wall 14 by the connector. The first bending plate 4 and the second bending plate 5 are each independently connected to the other end of the main board 1 by the bending portion and can be bent along the plane perpendicular to the main board 1. The connecting plate 6 is between the first bending plate 4 and the second bending plate 5, with one end integrally formed with the main board 1 and the other end detachably connected to the connector through the first mounting hole 11.

[0026] The bending section is used to bend the first bending plate 4 and the second bending plate 5 to prevent damage and breakage. Specifically, it will be designed as follows: The bending section 20 includes a fold line 21, a front bending section 24, a rear bending section 23, and an edge bending section 7; the fold line 21 is independently the bending boundary line after the first bending plate 4, the second bending plate 5, and the main plate 1 are bent; the front bending section 24 is at least one slot, parallel to the fold line 21 and located on the first bending plate 4 and the second bending plate 5; the rear bending section 23 includes one slot and another slot perpendicular to the slot direction, the slots are parallel to the fold line 21 and located on the main plate 1; the edge bending section 7 is the first bending plate 4 and the second bending plate 5 on both sides of the fold line 21, and has a wavy curve structure.

[0027] The first fixing plate 2 and the second fixing plate 3 each independently include a second mounting hole 22, a first convex plate 8, and a second convex plate 9; two of the first convex plates 8 and the second convex plates 9 are independently provided, with the two being spaced apart and located on the same side away from the wall 14; the second mounting hole 22 is installed between the two convex plates and is used to place connecting screws to fix it to the wall 14.

[0028] It also includes a third mounting hole 10, which is provided in multiples and is independently provided on the first bending plate 4 and the second bending plate 5, for placing connecting screws to fix the insulation plate 15.

[0029] Example 1

[0030] See Figure 3-4 The connector includes a hook bending plate 18 and an L-shaped extension plate 12; wherein the L-shaped extension plate 12 is a structure with two sets of L-shaped structural plates fixed at one end and open at the other end; there are two hook bending plates 18, both of which are L-shaped structures, and one end of each hook bending plate 18 is connected to the open end of the L-shaped extension plate 12.

[0031] One end of the L-shaped extension plate 12 is inserted into the outer wall 17; one end of the hook bending plate 18 is installed in the first mounting hole 11 of the connecting plate 6.

[0032] Example 2

[0033] See Figure 5 As shown, the connector includes an extension plate 26 and mounting screws 25; one end of the extension plate 26 is detachably connected to the first mounting hole 11 by a set of mounting screws 25.

[0034] Example 3

[0035] See Figure 2 As shown, a channel 19 is provided in the middle of the main board 1. There are at least two channels, and they cannot be through channels. The channel is used to increase the friction between the insulation board 15 and the main board 1 to prevent slippage.

[0036] When using the building insulation board anchor, first bend the first bending plate 4 and the second bending plate 5 radially along the bending section 20 at the fold line 21, and bend them upward and downward respectively. Then, use screw connectors to connect the first fixing plate 2 and the second fixing plate 3 upward and downward respectively at the second mounting hole 22, and then install them independently on the wall 14. Place the insulation board 15 on the upper and lower surfaces of the main board 1. Then, use screws in the third mounting hole 10 to install the first bending plate 4 and the second bending plate 5 to the insulation board.

[0037] Depending on the working conditions, the connectors can be selected as hook-shaped bent plate 18 and L-shaped extension plate 12. Hooks are installed at the corresponding connector positions on the exterior wall 17 to match the L-shaped extension plate 12, allowing them to be directly hooked together, thus enhancing installation stability. Alternatively, depending on the working conditions, the connectors can be selected as extension plate 26, which is installed at the corresponding positions on the exterior wall 17, further improving stability.

[0038] Considering that the insulation board 15 may change in volume in case of an accident, a certain gap will be left between the wall 14 and the exterior wall 17 during installation.
