Abstract
Description
Technical Field
[0001] This utility model relates to the field of external wall insulation engineering technology, and in particular to an anchor for external wall insulation engineering. Background Technology
[0002] In exterior wall insulation construction, mortar is usually applied to the side of the insulation board closest to the wall, the insulation board is then pasted onto the wall, and then it is nailed to the wall with insulation nails. Next, a finishing layer is applied to the outside of the insulation board, with finishing mortar applied to the outside of the insulation board and a layer of alkali-resistant mesh fabric pressed into the finishing mortar.
[0003] However, existing insulation nails can only nail a single insulation board to the wall, not connect several insulation boards into a whole. Especially in strong winds, the increased airflow velocity over the building surface leads to a decrease in pressure in that area. The air pressure in the gap between the insulation board and the wall in this area is greater than the external air pressure. This pressure difference acts like a giant suction cup, continuously "sucking" the insulation layer outward. When some insulation boards are not properly anchored, these boards are prone to falling off. At this point, a point of failure appears on the wall, forming a "breakthrough" for large-scale damage, which can trigger a chain reaction, making subsequent insulation boards very easy to fall off. In addition, although applying a plaster layer to the outside of the insulation board can improve its integrity, the ability to improve the overall integrity of the insulation board by simply relying on the adhesion between the plaster mortar and the insulation board is limited. Utility Model Content
[0004] To address the problems in the prior art, this utility model provides an anchor for external wall insulation projects.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: An anchor for external wall insulation engineering, comprising: An insulation board anchoring assembly includes a grid-shaped first connector with a first anchor in the middle. The first anchor penetrates the insulation board, with one end anchored to the wall and the other end providing a clamping force towards the wall to the outer surface of the insulation board away from the wall. The first connector is also provided with a plurality of first insulation board anchors, which are anchored in the insulation board. During operation, the insulation board anchoring assembly anchored between adjacent insulation boards is used to anchor and connect adjacent insulation boards. The surface layer anchoring assembly includes a mesh-like second connector disposed within the surface layer. Several surface layer anchors are arranged within the second connector, extending forward and backward respectively to form a front anchoring portion and a rear anchoring portion. The front anchoring portion is anchored in the insulation board, and the rear anchoring portion is anchored in the surface layer, used to anchor and connect the surface layer and the insulation board, improving the overall integrity of the connection between the surface layer and the insulation board.
[0006] Preferably, the first insulation board anchor is a fishbone-shaped anchor, which includes a first rod extending rearward from the front end of the first connector. The first rod is provided with a plurality of first anchoring protrusions arranged in a barb-like manner, and the first anchoring protrusions extend obliquely from the surface of the first rod toward the first connector.
[0007] Preferably, the first connector has an anchoring ring in the middle that is compatible with the first anchor.
[0008] Preferably, the first connector is a star-shaped grid, including outer rectangular grid lines and star-shaped grid lines connected in the middle of the rectangular grid lines.
[0009] Preferably, the plurality of first insulation board anchors are respectively arranged at the midpoint of the upper side, the midpoint of the lower side, and the four corners of the cross-shaped grid.
[0010] Preferably, the second connector is composed of a number of continuously and uniformly distributed square-shaped grid units.
[0011] Preferably, both the front anchoring part and the rear anchoring part are fishbone shaped.
[0012] Preferably, the front anchoring part includes a front anchoring part rod extending forward from the second connector and a plurality of front anchoring part protrusions. The front anchoring part protrusions are arranged in a barb-like shape and extend obliquely from the front anchoring part rod towards the second connector. The rear anchoring part includes a rear anchoring part rod extending rearward from the second connector and a number of rear anchoring part protrusions. The rear anchoring part protrusions are arranged in a barb-like shape and extend obliquely from the rear anchoring part rod toward the second connector.
[0013] The beneficial effects of this utility model are: 1. The insulation board anchoring assembly anchors a single insulation board to the wall through the first anchor in the middle. Adjacent insulation boards are anchored together as a whole through the first insulation board anchor and the grid-shaped first connector. The adjacent insulation boards have good coordination and jointly resist wind load (negative wind pressure), which further improves the safety of the insulation project.
[0014] 2. The mesh-like second connector of the plaster layer anchoring component is set in the plaster layer to connect the plaster layer into a whole. Several plaster layer anchors are arranged in the second connector. The plaster layer anchors extend forward and backward to form a front anchor part and a rear anchor part. The front anchor part is anchored in the insulation board, and the rear anchor part is anchored in the plaster layer. It is used to anchor and connect the plaster layer and the insulation board. The plaster layer is not easy to detach from the insulation board, which improves the integrity of the connection between the plaster layer and the insulation board. The plaster layer and the insulation board together resist wind load (negative wind pressure) and further improve the safety of the insulation project. Attached Figure Description

[0024] To facilitate the connection between the first connector and the first anchor, an anchoring ring 2 adapted to the first anchor is provided in the middle of the first connector. In this embodiment, the anchoring ring 2 is preferably annular.
[0025] In this embodiment, the first anchor is preferably an external wall insulation nail (not shown). The external wall insulation nail includes a rod and a disc. The rod of the external wall insulation nail passes through the anchoring ring 2 and its disc abuts against the anchoring ring 2.
[0026] The plastering layer anchoring assembly includes a mesh-like second connector, in which a plurality of plastering layer anchors 5 are arranged. The plastering layer anchors 5 extend forward and backward respectively to form a front anchoring part 52 and a rear anchoring part 51. The front anchoring part is anchored in the insulation board 6, and the rear anchoring part is anchored in the plastering layer, which is used to anchor and connect the plastering layer and the insulation board, thereby improving the overall integrity of the connection between the plastering layer and the insulation board.
[0027] In this embodiment, the second connector is composed of a number of continuously and uniformly distributed square-shaped grid units 41.

[0031] External wall insulation nails are existing technology, and their structure and principle are unrelated to the inventive point of this utility model, so they will not be described in detail here.
[0032] Taking low-rise buildings as an example, the working principle of this utility model is as follows: Step 1: After applying mortar to the side of the insulation board 6 that will be in contact with the wall, attach the insulation board 6 to the wall for initial fixation.
[0033] Step 2: First, drill anchoring holes at the four corners and center of the insulation board 6, extending them into the corresponding wall. Then, align the anchoring ring 2 of the insulation board anchoring assembly with the anchoring hole. The external wall insulation nail passes through the anchoring ring 2 and is driven into the anchoring hole for anchoring, ensuring that the disc part of the external wall insulation nail abuts against the anchoring ring 2. Next, straighten and flatten the cross-shaped grid 3. Finally, insert the corresponding herringbone-shaped anchor 1 into the insulation board by hand. Repeat the above operations until all insulation board anchoring assemblies are anchored. At this point, the insulation board anchoring assembly has anchored and connected all the insulation boards into a whole.
[0034] Step 3: First, evenly apply the base layer mortar of the plastering layer to the side of the insulation board away from the wall. Then, after flattening the plastering layer anchoring component, insert the rear anchoring part 51 of the plastering layer anchor 5 into the insulation board, so that the front anchoring part 52 of the plastering layer anchor 5 is covered by the base layer mortar of the plastering layer. Finally, carry out the surface mortar leveling construction of the plastering layer. After the plastering layer mortar has solidified, the plastering layer anchoring component will form the plastering layer mortar and the insulation board into a whole.
