Description

Technical Field

[0001] This utility model belongs to the field of building exterior wall insulation construction technology, specifically an adaptive anchor bolt device for water-repellent rock wool board insulation construction. Background Technology

[0002] In the construction of building exterior wall insulation systems, anchors are used to fix the insulation boards to the wall. Traditional anchors are prone to problems during construction, such as insecure installation, drilling errors leading to incomplete anchor fit, or poor adaptability to different substrates. Furthermore, traditional anchors require pre-determined drilling positions and depths, demanding high construction precision. Uneven or uneven substrates can cause anchor failure due to insecure anchoring. Additionally, metal anchors are prone to thermal bridging, reducing insulation performance. Therefore, it is necessary to provide an adaptive anchor device for hydrophobic rock wool board insulation construction to address the problems mentioned in the background. Utility Model Content

[0003] To achieve the above objectives, this utility model provides the following technical solution: an adaptive anchor bolt device for water-repellent rock wool board insulation construction, comprising an elastic sleeve assembly, an anchor bolt assembly, a heat insulation gasket, and a waterproof embedded plate.

[0004] The anchor bolt assembly includes an expansion sleeve, a bolt body is slidably connected inside the expansion sleeve, one end of the bolt body is fixed with a cone head, and a strip groove is opened at the end of the expansion sleeve.

[0005] The other end of the plug is threaded with a nut, and a torque feedback loop is provided between the nut and the waterproof embedded plate.

[0011] Multiple pressure sensors are distributed on the inclined inner wall of the torque feedback loop.

[0012] Furthermore, preferably, the torque feedback loop is electrically connected to a buzzer and an LED light-emitting element.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0023] Please see Figures 1-5 In this embodiment of the utility model, an adaptive anchor bolt device for thermal insulation construction of water-repellent rock wool board includes an elastic sleeve assembly 4, an anchor bolt assembly 2, a heat insulation pad 3, and a waterproof embedded plate 12. The elastic sleeve assembly 4 is installed inside the wall 11. The anchor bolt assembly 2 passes through the elastic sleeve assembly 4 and is inserted into a hole drilled in the wall 11. The heat insulation pad 3 and the waterproof embedded plate 12 are both sleeved at the ends, and the heat insulation pad 3 is located between the waterproof embedded plate 12 and the rock wool board 1.

[0024] The anchor bolt assembly 2 includes an expansion sleeve 21, in which a bolt body 22 is slidably connected. One end of the bolt body 22 is fixed with a cone head 23, and the end of the expansion sleeve 21 is provided with a strip groove 24. This allows the cone head 23 to deform and expand as the bolt body 22 slides, so that the expansion sleeve 21 is in close contact with the borehole wall.

[0025] The other end of the bolt body 22 is threaded with a nut 25. A torque feedback ring 5 is provided between the nut 25 and the waterproof embedded plate 12. It should be noted that after the bolt body 22 is installed, the length of its exposed end is no more than 5mm. The total thickness of the on-site 5mm thick plastering mortar (with an inner layer of alkali-resistant fiberglass mesh) + alkali-resistant sealing primer + real stone paint is about 8mm or 9mm.

[0026] Specifically, the rock wool board insulation wall construction project includes, from the outside to the inside, the following:

[0027] 1. One coat of topcoat;

[0028] 2. One coat of main paint;

[0029] 3. Divide the wall into sections according to the design;

[0030] 4. One coat of primer (alkali-resistant sealing primer);

[0031] 5. Apply water-resistant putty, and sand it after it dries (1-5 coats or refer to the manufacturer's specific process).

[0032] 6.5mm thick plastering mortar (with an inner layer of alkali-resistant fiberglass mesh + no less than 7 anchors per square meter);

[0033] 7.70mm thick hydrophobic rock wool board (p=80-200).

[0034] In this embodiment, the elastic sleeve assembly 4 consists of a sleeve 42 and a fixing sleeve 41. The fixing sleeve 41 is embedded and fixed in the drilled hole in the wall 11. The inner wall of the fixing sleeve 41 is provided with a spiral groove 43. The sleeve 42 is movably connected to the fixing sleeve 41 through the spiral groove 43, thereby allowing the sleeve to automatically adjust the angle (±15°) according to the unevenness of the wall during installation to compensate for the drilling deviation.

[0035] In a preferred embodiment, both the sleeve 42 and the fixing sleeve 41 are made of nylon or composite materials, which have corrosion resistance and low thermal conductivity.

[0036] In this embodiment, the expansion sleeve 21 has a plurality of side protrusions 26 distributed on its side wall. The cross-section of the side protrusions 26 is an inverted U-shaped structure, so that when the expansion sleeve 21 is initially installed, it can automatically expand and deform according to pressure after contacting the base layer, thereby ensuring a tight fit with the hole wall.

[0037] In this embodiment, the heat insulation pad 3 is composed of an outer EPDM rubber 31 and an inner aerogel 32. The outer EPDM rubber 31 is used for waterproof sealing, while the inner aerogel 32 is used to block heat conduction. The outer EPDM rubber 31 is wrapped around the outer side of the inner aerogel 32 to improve the tightness of installation.

[0038] In this embodiment, a top ring 51 is sleeved on the bolt body 22 between the nut 25 and the torque feedback ring 5. The top ring 51 is in contact with the torque feedback ring 5 and the contact surface is set as an inclined structure.

[0039] Multiple pressure sensors 52 are distributed on the inclined inner wall of the torque feedback ring 5. During installation, the pressure sensors 52 monitor pressure changes and issue a prompt when the preset torque is reached, thus preventing damage to the rock wool board due to excessive tightening.

[0040] In a preferred embodiment, the torque feedback loop 5 is electrically connected to a buzzer and an LED light-emitting element for easy warning.

[0041] The specific usage steps are as follows:

[0042] (1) Drilling stage

[0043] Use the matching drill bit (with depth limiter) to ensure consistent drilling depth.

[0044] (2) Installation phase

[0045] After the anchor bolt is inserted, the sleeve 42 in the elastic sleeve assembly 4 adapts to the wall angle deviation through deformation.

[0046] When the nut is rotated 25, the expansion bolt expands in stages, and the torque feedback ring 5 provides real-time torque feedback to prevent the rock wool board from cracking under pressure.

[0047] (3) Sealing stage

[0048] After the heat insulation pad 3 is compressed, the outer layer of EPDM rubber 31 seals the gaps around the anchor bolt to prevent water seepage.

[0049] This invention features an adaptive anchor bolt with automatic adjustment functions, such as angle adjustment, depth adjustment, or pressure sensing, ensuring stable installation under various conditions. This device is adaptable to different substrate conditions, easy to install, reliably fixed, corrosion-resistant, and reduces thermal bridging effects. It is well-suited for use in the insulation construction of water-repellent rock wool boards.

[0050] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
