Description

Technical Field

[0001] This utility model relates to external wall insulation boards, and in particular to an anchoring device for external wall insulation boards. Background Technology

[0002] External wall insulation boards are commonly used materials in building external wall insulation systems. They are mainly used to improve the thermal insulation performance of buildings and reduce energy consumption, while also having functions such as fire resistance, waterproofing, and sound insulation.

[0003] External wall insulation boards are typically fixed to the exterior wall using mortar bonding and insulation nail anchoring. After installation, mechanical fixing is generally used to enhance the connection strength between the insulation board and the base wall, preventing it from falling off.

[0004] Mechanical anchoring is generally achieved through expansion bolts or hammer bolts. However, existing anchoring methods are prone to loosening or failure when subjected to external loads or vibrations. Furthermore, in areas with poor geological conditions or loose soil and rock, the anchoring effect of traditional anchors is often unsatisfactory and fails to meet engineering requirements. Utility Model Content

[0005] In order to solve the problem that fixed methods in the background art are prone to loosening or failure when subjected to external loads or vibrations, this utility model proposes an anchoring device for external wall insulation boards.

[0006] The technical solution of this utility model is as follows: it includes a cylinder, multiple extension components, and a driving component.

[0007] The cylinder has a connecting cavity inside, and the connecting cavity is open from top to bottom. The inner wall of the connecting cavity has multiple sliding openings arranged around the cylinder axis, and the sliding openings penetrate the outer surface of the cylinder.

[0008] The extension component is axially arranged around the cylinder. The extension component includes an arc-shaped top plate and a connecting rod. The side of the arc-shaped top plate near the cylinder is fixedly connected to the connecting rod.

[0009] The connecting rod passes through the sliding opening and extends into the connecting cavity, and the outer surface of the connecting rod is slidably connected to the sliding opening;

[0010] The driving component is vertically arranged and located inside the connecting cavity. The driving component includes a driving part and a conical plug. The lower end of the driving part is fixedly connected to the top of the conical plug. The lower end of the conical plug extends out of the connecting cavity. The driving part is used to drive the radial movement of the arc-shaped top plate by moving up and down.

[0011] Preferably, the driving component further includes a connecting part and a tapered plug, wherein the connecting part is fixedly connected to the upper end of the driving part, and the lower end of the driving part is fixedly connected to the tapered plug;

[0012] The top of the cylinder has a threaded connection port, and the connecting part is a screw. The screw is threadedly connected to the threaded connection port, and the bottom of the screw is fixedly connected to the top of the drive part.

[0013] Preferably, the driving part includes a tapered rod, which has a tapered structure that is wider at the top and narrower at the bottom, and the top of the tapered rod is fixedly connected to the screw.

[0022] 1. The insulation board can be pre-installed and quickly connected to the mounting holes opened on the wall during the connection process between the insulation board and the wall.

[0023] 2. The outward expansion of the arc-shaped top plate increases the friction with the inner wall of the mounting hole, while also ensuring that the cylinder is centered within the mounting hole and does not easily wobble.

[0024] 3. When the inner diameter of the mounting hole becomes larger and the cylinder does not fit the mounting hole, causing wobbling, screw 2 can be rotated to keep the arc-shaped top plate pressed against the inner wall of the mounting hole. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1: This example aims to propose an anchoring device for external wall insulation boards.

[0031] according to Figures 1-2 As shown, it includes a cylinder 1, multiple extension parts and a drive part.

[0032] The cylinder 1 has a connecting cavity inside, and the connecting cavity is open from top to bottom. The inner wall of the connecting cavity has multiple sliding openings arranged axially around the cylinder 1, and the sliding openings penetrate the outer surface of the cylinder 1.

[0033] The cylinder 1 is used to insert into the pre-drilled mounting hole on the wall.

[0034] The top of the cylinder 1 is fixedly connected to an ear plate 3, and the ear plate 3 has bolt holes 4. Bolts are inserted through the bolt holes 4 for connection with the insulation board.

[0035] The extension component is axially arranged around the cylinder 1. The extension component includes an arc-shaped top plate 6 and a connecting rod 10. The side of the arc-shaped top plate 6 near the cylinder 1 is fixedly connected to the connecting rod 10. The connecting rod 10 passes through the sliding opening and extends into the connecting cavity, and the outer surface of the connecting rod 10 is slidably connected to the sliding opening.

[0036] The connecting rod 10 includes a top plate 9, which is fixedly connected to one end of the connecting rod 10 near the cylinder 1. The end of the connecting rod 10 near the arc-shaped top plate 6 is fixedly connected to the outer surface of the arc-shaped top plate 6.

[0037] The top plate 9 is located inside the connecting cavity, and the width of the top plate 9 is greater than the width of the sliding opening, thereby preventing the top plate 9 from being pushed out of the connecting cavity.

[0038] The driving component is vertically arranged and is located inside the connecting cavity. The driving component includes a driving part and a conical plug 8. The lower end of the driving part is fixedly connected to the top of the conical plug 8. The lower end of the conical plug 8 extends out of the connecting cavity. The conical plug 8 is used to penetrate into the wall after a hole is made in the wall to improve the connection strength between the cylinder 1 and the wall.

[0039] The driving component also includes a connecting part and a conical plug 8. The connecting part is fixedly connected to the upper end of the driving part, and the lower end of the driving part is fixedly connected to the conical plug 8. The top of the cylinder 1 is provided with a threaded connection port. The connecting part is a screw 2. The screw 2 is threadedly connected to the threaded connection port. The bottom of the screw 2 is fixedly connected to the top of the driving part. The top of the screw 2 is fixedly connected with a screw head 5. The screw head 5 facilitates the rotation of the screw 2 by a rotating tool, thereby increasing the friction between the arc-shaped top plate 6 and the wall of the mounting hole.

[0040] The drive unit includes a tapered rod 7, which has a tapered structure that is wider at the top and narrower at the bottom. The top of the tapered rod 7 is fixedly connected to the screw 2, and the lower end of the tapered rod 7 is fixedly connected to the upper part of the tapered plug 8. The top plate 9 is in contact with the outer surface of the tapered rod 7.

[0041] The top plate 9 is an arc-shaped structure extending in the vertical direction, which increases the contact area between the top plate 9 and the tapered rod 7.

[0042] Working principle: First, the cylinder 1 is installed into the insulation board through the bolt hole 4. The installation method is to make a hole in the insulation board, insert the cylinder 1 into the hole, and then reinforce it with bolts.

[0043] Then, an installation hole is made in the wall, and the cylinder 1 is inserted into the installation hole. The driving component is then inserted into the cylinder 1 and rotated, so that the screw 2 is threadedly connected to the threaded connection port, thereby causing the tapered rod 7 to move downward, which in turn causes the top plate 9 to be squeezed by the tapered rod 7, thus causing the top plate 9 to move away from the tapered rod 7, thereby pushing the connecting rod 10 to move, and finally causing the arc-shaped top plate 6 to move outward. Multiple arc-shaped top plates 6 move outward and contact the inner wall of the installation hole, providing support for the installation hole and centering the cylinder 1.

[0044] This allows the arc-shaped top plate 6 to contact the inside of the mounting hole, creating a supporting effect and increasing the friction between the cylinder 1 and the inner wall of the mounting hole. It also keeps the cylinder 1 centered, preventing it from tilting and loosening during prolonged use. Furthermore, if, after prolonged use, external loads and vibrations cause repeated friction between the cylinder 1 and the inner wall of the mounting hole, causing the inner wall to expand, the screw 2 can be rotated to allow the tapered rod 7 to continue moving, further expanding the arc-shaped top plate 6 to match the inner diameter of the mounting hole. This prevents loosening or failure due to external loads or vibrations.

[0045] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims and not by the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
