[0002] External wall insulation technology is a technology that fixes a layer of external insulation board on the outer surface of the exterior wall through mortar bonding and insulation nail anchoring. This technology has significant advantages such as protecting the main structure, significant thermal insulation, improving wall moisture, and a wide range of applications. It can significantly reduce the energy consumption of cooling and heating in buildings.

[0003] The existing equipment has the following disadvantages: during the fixing process, traditional anchor rods often rely on the friction and adhesion between the rock and soil to achieve fixation. This fixing method is prone to loosening or failure when subjected to external loads or vibrations. Secondly, for some areas with poor geological conditions or loose rock and soil, the fixing effect of traditional anchor rods is often unsatisfactory and difficult to meet engineering requirements.

[0004] Therefore, the present application now proposes an external wall insulation board anchoring device to solve the above-mentioned problems. Utility Model Content

For some areas with poor geological conditions or loose rock and soil, the fixing effect of traditional anchor rods is often unsatisfactory.

[0006] To achieve the above object, the utility model provides the following technical solution: an external wall insulation board anchoring device, including an anchor rod, and also including:

[0007] An expansion sleeve, which is sleeved on the outside of the anchor rod and is used to fix the anchor rod in the wall when the anchor rod fixes the insulation board to the exterior wall;

[0008] A fixing unit, arranged on the expansion sleeve, for fixing the expanded expansion sleeve;

[0009] The fixing unit comprises:

[0010] A fixing rod, arranged at equal angles on the expansion sleeve;

[0011] The fixing device is arranged on a side of the fixing rod away from the expansion sleeve and is used for fixing the expanded expansion sleeve.

[0012] The anchor rod comprises a head, a screw rod fixed on one side of the head, and a tip end fixed on a side of the screw rod away from the head, and the screw rod is threadedly connected to the expansion sleeve.

[0013] The screw is arranged in a conical shape and the diameter of the thread gradually decreases toward the side close to the tip.

[0014] Wherein, the expansion sleeve includes a fixing pad sleeved on the screw rod, a fixing ring fixed on the fixing pad, an elastically arranged expansion piece fixed on the fixing ring away from the fixing pad, a sleeve ring fixed on the expansion piece away from the fixing ring, and a connecting section fixed on the sleeve ring, the connecting section is threadedly connected to the screw rod, and the fixing unit passes through the expansion piece.

[0015] The fixing rod is arranged corresponding to the position of the expansion piece, a fixing hole for the fixing rod to pass through is provided at the position of the expansion piece corresponding to the fixing rod, and an installation hole for installing the fixing device is provided at the position of the fixing rod corresponding to the fixing device.

[0016] Wherein, the fixing device comprises a connecting rod fixed in the mounting hole, a clamping block sleeved on the connecting rod, and an elastic member fixed on the clamping block near the inner wall of the fixing rod, and a mounting groove for the clamping block to move is provided at a position of the fixing rod corresponding to the connecting rod;

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1-8 The utility model provides a technical solution: an external wall insulation board anchoring device, including an anchor rod 1, and also including:

[0032] The expansion sleeve 2 is sleeved on the outside of the anchor rod 1 and is used to fix the anchor rod 1 in the wall when the anchor rod 1 fixes the insulation board to the exterior wall;

[0033] A fixing unit 3, arranged on the expansion sleeve 2, for fixing the opened expansion sleeve 2;

[0034] The fixing unit 3 comprises:

[0035] The fixing rod 31 is arranged at an equal angle on the expansion sleeve 2;

[0036] The fixing device 32 is arranged on a side of the fixing rod 31 away from the expansion sleeve 2 and is used to fix the expanded expansion sleeve 2.

[0037] It should be noted that during operation, a hole is drilled on the insulation wall and the wall through a drilling device, and then the expansion sleeve 2 is inserted into the drilled hole, and then the anchor rod 1 is inserted into the expansion sleeve 2, and then the anchor rod 1 is driven into the wall. During the opening process of the expansion sleeve 2, the fixing rod 31 is inserted into the expansion sleeve 2, and then the expansion sleeve 2 is fixed by the fixing device 32. The expansion sleeve 2 opens inside the drilled hole and squeezes the hole wall to form a strong friction force. This friction force can not only provide a stable fixing effect, but also when subjected to external loads or vibrations, the fixing device 32 can firmly lock the expansion sleeve 2, reducing the possibility of the expansion sleeve 2 loosening or failure under the action of vibration, and can adapt to various geological conditions, especially in loose rock and soil, the fixing effect of the expansion sleeve 2 and the anchor rod 1 is more significant, ensuring a stable connection between the anchor device and the wall, which not only improves the stability of the insulation board fixation, but also enhances its wind resistance, earthquake resistance and other capabilities.

[0038] In one embodiment, the anchor rod 1 includes a head 11 , a screw rod 12 fixed to one side of the head 11 , and a tip 13 fixed to a side of the screw rod 12 away from the head 11 . The screw rod 12 is threadedly connected to the expansion sleeve 2 .

[0039] With this design, during installation, it is only necessary to screw the anchor rod 1 into the wall hole. As the screw rod 12 goes deeper, the expansion sleeve 2 is automatically unfolded and fixed. At the same time, the fixing unit 3 automatically fixes the opened expansion sleeve 2 without the need for additional fixing tools or materials. This design greatly shortens the construction time and improves the construction efficiency.

[0040] In one embodiment, the screw rod 12 is configured in a conical shape and the diameter of the thread gradually decreases toward the tip 13 .

[0041] With this design, the screw 12 is set in a cone shape. Such a design can increase the connection force between the screw 12 and the expansion sleeve 2, so that the screw 12 is more tightly connected to the expansion sleeve 2 during the continuous tightening process, thereby improving the stability of the installation of the expansion sleeve 2. The tip 13 is fixed on the side of the screw 12 away from the head 11 for penetrating the wall.

[0042] In one embodiment, the expansion sleeve 2 includes a fixing pad 25 sleeved on the screw 12, a fixing ring 24 fixed on the fixing pad 25, an elastically arranged expansion piece 23 fixed on the fixing ring 24 away from the fixing pad 25, a sleeve ring 21 fixed on the side of the expansion piece 23 away from the fixing ring 24, and a connecting section 22 fixed on the sleeve ring 21, the connecting section 22 is threadedly connected to the screw 12, and the fixing unit 3 passes through the expansion piece 23.

[0043] With this design, the fixing ring 24 is fixed on the fixing pad 25, playing the role of connection and support. When the screw 12 is threadedly connected with the connecting section 22, the connecting section 22 is driven to move toward the side close to the fixing pad 25, thereby squeezing the expansion sheet 23. Since the expansion sheet 23 is elastically arranged, it can be opened outward when the screw 12 is tightened, so that the expansion sheet 23 is tightly fitted against the inner wall of the aperture.

[0044] In one embodiment, the fixing rod 31 is arranged corresponding to the position of the expansion piece 23, a fixing hole 231 for the fixing rod 31 to pass through is opened at the position of the expansion piece 23 corresponding to the fixing rod 31, and an installation hole 311 for installing the fixing device 32 is opened at the position of the fixing rod 31 corresponding to the fixing device 32.

[0045] With such a design, when the expansion sheet 23 is folded due to the squeezing action of the connecting section 22, the fixing rod 31 is inserted into the fixing hole 231 provided on the expansion sheet 23, and then when the expansion sheet 23 is fully opened and tightly fitted to the hole wall, the fixing device 32 is used to fix the opened expansion sheet 23.

[0046] In one embodiment, the fixing device 32 includes a connecting rod 321 fixed in the mounting hole 311, a clamping block 322 sleeved on the connecting rod 321, and an elastic member 323 fixed on the inner wall of the fixing rod 31 near the clamping block 322. The fixing rod 31 is provided with a mounting groove 312 for the clamping block 322 to move at a position corresponding to the connecting rod 321.

[0047] A limiting plate 313 for limiting the position of the elastic member 323 is fixedly disposed inside the mounting groove 312 . The elastic member 323 is made of a spring or an elastic pad.

[0048] With this design, when the clamping block 322 contacts the fixing hole 231, the clamping block 322 will, under the action of the expansion piece 23, move toward the inside of the fixing hole 231 at the contact portion of the clamping block 322 with the fixing hole 231, and then the lower end of the clamping block 322 will squeeze the elastic member 323. When the clamping block 322 passes through the fixing hole 231, the expansion piece 23 no longer squeezes and restricts the clamping block 322. Under the action of the elastic member 323, the clamping block 322 above the fixing hole 231 makes an outward expansion movement, and then the clamping block 322 clamps and fixes the expansion piece 23, thereby locking the position of the expansion piece 23 in the drill hole, reducing the risk of the expansion piece 23 loosening or falling off under the action of external force.

[0049] In one embodiment, a clamping end 3221 is obliquely disposed on a side of the clamping block 322 away from the connecting rod 321 .

[0050] With this design, the top of the snap-in block 322 is tilted, which makes it easy to insert the snap-in block 322 into the fixing hole 231, so that when the expansion piece 23 is opened outward, the snap-in block 322 automatically fixes the expansion piece 23 without the need for additional fixing tools or materials. This design greatly shortens the construction time and improves the construction efficiency.
