Description

Technical Field

[0001] This utility model relates to the field of insulation board anchoring technology, and in particular to an anchor for installing external wall insulation boards. Background Technology

[0002] In building exterior wall insulation projects, anchors are the core components connecting the insulation board and the wall structure. Their anchoring stability, ease of installation, and sealing and insulation performance directly affect the overall quality and service life of the insulation system. Currently, most mainstream exterior wall insulation board anchors on the market adopt the traditional structure of "nail rod + expansion sleeve". The sleeve is expanded by hammering or screwing in to achieve friction fixation with the drilled hole in the wall.

[0003] However, traditional anchors have many technical limitations in practical applications. For example, the reliability of anchoring depends on the local friction force after the sleeve expands. When the wall material is a low-density substrate such as lightweight brick or aerated concrete, the anchor is prone to loosening due to insufficient bearing capacity of the drilled sidewall. After long-term use, this may cause the insulation board to become hollow and fall off. At the same time, there is often a gap between the nail rod and the drilled hole of traditional anchors. External cold air and rainwater can easily seep into the interior of the wall through the gap, destroying the continuity of the insulation layer and leading to increased building energy consumption. In addition, rainwater infiltration may also cause problems such as dampness and mold growth in the wall.

[0004] Therefore, it is necessary to provide a new type of anchor for installing external wall insulation panels to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an anchor for installing external wall insulation panels.

[0006] The anchor for installing external wall insulation panels provided by this utility model includes a nail rod, which has a hollow cavity inside. The nail rod has multiple annularly distributed side cavities near the bottom of the hollow cavity. Each side cavity is equipped with a rotatably connected side pressure plate. The side pressure plate has a T-shaped groove, and the depth of the T-shaped groove decreases from the head end of the side pressure plate to the rotating end of the side pressure plate.

[0007] A threaded push column with a threaded connection is inserted into the hollow cavity, and a central connecting rod is fixedly installed at the insertion end of the threaded push column. An installation column is fixedly installed at the head of the central connecting rod. A rotating ring with a rotatable connection is sleeved on the installation column, and multiple T-shaped sliders with annular distribution are fixedly installed on the rotating ring. The T-shaped sliders are inserted into the T-shaped sliding grooves opened in the corresponding side pressure plates and are slidably connected to the T-shaped sliding grooves.

[0008] The nail rod has an arc-shaped cavity distributed in a ring, and the nail rods on both sides of the arc-shaped cavity are fixedly connected by multiple ring-shaped connecting rods. The nail rods on both sides of the connecting rods are fixedly installed with semi-circular rubber airbags arranged inside and outside, and the two semi-circular rubber airbags form an annular closed bladder structure.

[0009] Preferably, the inner wall of the nail rod near the cavity opening is provided with an internal thread portion that matches the threaded push post, and the nail rod is provided with a threaded hole coaxial with the hollow cavity, and a threaded rod that matches the threaded hole is fixedly installed on the mounting post.

[0010] Preferably, the outer wall of the side pressure plate is fixedly fitted with a plurality of evenly distributed serrated portions.

[0011] Preferably, a stop piston is fixedly sleeved on the central connecting rod, and the stop piston is located between the annular closed bladder structure and the threaded propulsion column.

[0012] Preferably, one end of the threaded push rod extends into a nail rod and is fixedly fitted with a knob.

[0013] Preferably, one end of the nail rod is provided with an integrally formed nail head, and the head of the nail rod is fixedly sleeved with a pressing plate.

[0014] Compared with related technologies, the anchor for installing external wall insulation panels provided by this utility model has the following advantages:

[0015] Beneficial effects:

[0016] 1. The rotating threaded push column of this utility model allows the threaded push column to rotate along the internal thread. Since the depth of the T-shaped slide decreases from the head end of the side pressure plate to the rotating end of the side pressure plate, when the T-shaped slide head slides along the T-shaped slide, the side pressure plate can expand outward around the rotating axis, thereby engaging with the inner wall of the drill hole and fixing the nail rod.

[0017] 2. When the threaded pusher of this utility model rotates along the internal thread, the abutting piston presses against the inner semi-circular rubber airbag. Therefore, the inner semi-circular rubber airbag is compressed, driving gas to rush into the outer semi-circular rubber airbag. As a result, the outer semi-circular rubber airbag extends outward. On the one hand, it improves the damping effect between the nail rod and the drill hole. On the other hand, the expanded outer semi-circular rubber airbag can fill the gap between the nail rod and the drill hole, improving the insulation effect of the insulation board. At the same time, it avoids the hidden danger that external cold air and rainwater can easily seep into the interior of the wall through the gap, thereby damaging the insulation layer.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0026] Please see Figures 1 to 5 This utility model provides an anchor for installing an external wall insulation board, which includes a nail rod 1, a threaded push column 4, and a side pressure plate 5.

[0027] In the embodiments of this utility model, please refer to Figures 1 to 5 The nail rod 1 has an integrally formed nail head 11 at one end, and a pressing plate 12 is fixedly sleeved on the head of the nail rod 1. The nail rod 1 has a hollow cavity 1a inside, and the nail rod 1 has multiple annularly distributed side cavities 1c near the bottom of the hollow cavity 1a. Each side cavity 1c is equipped with a rotatably connected side pressure plate 5, and a T-shaped groove 5a is provided on the side pressure plate 5. The depth of the T-shaped groove 5a decreases from the plate head end of the side pressure plate 5 to the rotating end of the side pressure plate 5. The side pressure plate 5 is located in the side cavity 1c, and the end of the side pressure plate 5 near the nail head 11 is rotatably connected to the two side walls of the side cavity 1c through a rotating shaft.

[0028] A threaded push column 4 with a threaded connection is inserted into the hollow cavity 1a, and a central connecting rod 41 is fixedly installed at the insertion end of the threaded push column 4. An installation column 42 is fixedly installed at the head of the central connecting rod 41. A rotating ring 44 with a rotating connection is sleeved on the installation column 42, and multiple T-shaped slide heads 45 distributed in annularly are fixedly installed on the rotating ring 44. The T-shaped slide heads 45 are inserted into the T-shaped slide groove 5a opened in the corresponding side pressure plate 5 and are slidably connected to the T-shaped slide groove 5a. The nail rod 1 is provided with an internal thread part 13 that matches the threaded push column 4 on the inner wall near the cavity opening of the hollow cavity 1a. One end of the threaded push column 4 extends out of the nail rod 1 and is fixedly installed with a knob 47.

[0029] It should be noted that: holes are drilled in advance on the exterior wall and the insulation board (the hole diameter is smaller than the rod diameter of nail rod 1), and then nail rod 1 is driven into the drilled holes. Then, the threaded push column 4 is rotated so that the threaded push column 4 is screwed in along the internal thread 13. Since the depth of the T-shaped slide groove 5a decreases from the plate head end of the side pressure plate 5 to the rotating end of the side pressure plate 5, when the T-shaped slide head 45 slides inward along the T-shaped slide groove 5a, the side pressure plate 5 can expand outward around the rotating axis, thereby engaging with the inner wall of the drilled hole and fixing nail rod 1.

[0030] In this embodiment, since the T-shaped slide head 45 is rotatably mounted on the mounting post 42 via the rotating ring 44, the threaded push post 4 is not restricted from rotating along the internal thread 13.

[0031] Furthermore, a threaded hole 1b coaxially arranged with the hollow cavity 1a is provided in the nail rod 1, and a threaded rod 43 matching the threaded hole 1b is fixedly installed on the mounting column 42. The threaded rod 43 can be screwed into the threaded hole 1b, which further improves the stability of the threaded push column 4 in the nail rod 1.

[0032] Furthermore, the outer wall of the side pressure plate 5 is fixedly fitted with multiple evenly distributed serrated portions 51, thereby enabling the side pressure plate 5 to better achieve mechanical engagement with the drilled side wall.

[0033] In the embodiments of this utility model, please refer to Figures 1 to 5 The nail rod 1 has an arc-shaped annular cavity 1d distributed in a ring. The nail rods 1 on both sides of the arc-shaped annular cavity 1d are fixedly connected by multiple annularly distributed connecting rods 2. The nail rods 1 on both sides of the connecting rods 2 are fixedly installed with inner and outer semi-circular rubber airbags 3. The two semi-circular rubber airbags 3 form an annular closed bladder structure. The connecting rod 41 is fixedly fitted with an abutting piston 46, and the abutting piston 46 is located between the annular closed bladder structure and the threaded push column 4.

[0034] It should be noted that during the process of nailing the rod 1 into the drill hole, the gas in the outer semi-circular rubber air bladder 3 rushes into the inner semi-circular rubber air bladder 3, causing it to expand. When the threaded push column 4 rotates along the internal thread 13, the abutting piston 46 presses the inner semi-circular rubber air bladder 3 together. Therefore, the inner semi-circular rubber air bladder 3 is compressed, driving the gas to rush into the outer semi-circular rubber air bladder 3. As a result, the outer semi-circular rubber air bladder 3 extends outward. On the one hand, it improves the damping effect between the nail rod 1 and the drill hole. On the other hand, the expanded outer semi-circular rubber air bladder 3 can fill the gap between the nail rod 1 and the drill hole, improving the insulation effect of the insulation board. At the same time, it avoids the hidden danger that external cold air and rainwater can easily seep into the interior of the wall through the gap, thereby damaging the insulation layer.

[0035] The semi-circular rubber airbag 3 is made of low-temperature resistant EPDM rubber, which can maintain good elasticity in the range of -40℃ to 150℃, avoiding the problem of low-temperature hardening. In addition, a wear-resistant layer is set on the outer surface of the semi-circular rubber airbag 3 (the specific material is selected according to actual needs), thereby reducing the problem of the semi-circular rubber airbag 3 breaking due to wear.

[0036] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
