Technical Field

[0001] The utility model relates to the technical field of connecting pieces, and more particularly to a penetration-type fastening anchor bolt. Background Art

[0002] At present, in the production process of composite panels, anchor bolts are needed to anchor and connect several of them. In the prior art, screw-in thermal insulation anchor bolts are often used to anchor and connect the boards in the composite panels. The existing thermal insulation anchor bolts require high precision if they are screwed in by equipment, so they are mostly screwed in manually. At the same time, since the screwed expansion anchor bolts have a threaded structure inside and the inner wall is relatively thin, when the correct screw-in method is not used and it is directly knocked in, the size of the anchoring force is difficult to control. In addition, manually screwing in the bolt rod not only has low work efficiency, but also has high labor intensity, which affects the construction efficiency.

[0003] Therefore, how to provide a penetration-type fastening anchor bolt that can quickly anchor and connect the panels in a composite panel is a problem that those skilled in the art need to solve urgently. Utility Model Content

[0008] A nail body, wherein the outer diameter of the nail body is greater than the inner diameter of the easily deformable portion;

[0009] When the nail body is nailed into the sleeve from the end of the sleeve away from the easily deformable portion, the nail body can expand the easily deformable portion, thereby improving the anchoring ability of the easily deformable portion through the anti-slip structure.

[0010] According to the penetration-type fastening anchor bolt provided by the utility model, the easily deformable portion and the sleeve are integrally formed.

[0011] According to the penetration-type fastening anchor bolt provided by the utility model, the anti-slip structure is a barb structure.

[0012] The penetration-type fastening anchor bolt provided by the utility model further includes a pressure plate, which is connected to an end of the sleeve away from the deformable portion, and is provided with a through hole coaxially arranged with the inner cavity of the sleeve.

[0013] According to the penetration-type fastening anchor bolt provided by the utility model, the through hole is a stepped hole, and the stepped hole is used to cooperate with the nail cap of the nail body so that the nail cap sinks into the stepped hole.

[0014] According to the penetration-type fastening anchor bolt provided by the utility model, the pressure plate is a disc structure, and the pressure plate is coaxially arranged with the sleeve.

[0026] 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.

[0027] See also Figure 1-5 The embodiment of the utility model discloses a penetration-type fastening anchor bolt, comprising: a sleeve 1 and a nail body 2.

[0028] One end of the sleeve 1 is provided with an easily deformable portion 3 coaxially arranged with the sleeve 1. The easily deformable portion 3 is a tubular structure. An anti-slip structure 4 is provided on the outer surface of the easily deformable portion 3. The inner diameter of the easily deformable portion 3 is smaller than the inner diameter of the sleeve 1. The easily deformable portion 3 is provided with at least two openings 5 ​​from the end away from the sleeve 1 to the end close to the sleeve 1.

[0029] The outer diameter of the nail body 2 is larger than the inner diameter of the easily deformable portion 3; preferably, the outer diameter of the nail body 2 is slightly smaller than the inner diameter of the sleeve 1. When the nail body 2 is nailed into the inner cavity of the sleeve 1, the outer diameter of the nail body 2 can expand the easily deformable portion 3. Under the action of the opening 5 provided on the easily deformable portion 3, the easily deformable portion 3 opens in a petal shape.

[0030] When the nail body 2 is nailed into the sleeve 1 from the end of the sleeve 1 away from the deformable portion 3 , the nail body 2 can expand the deformable portion 3 and enhance the anchoring ability of the deformable portion 3 through the anti-slip structure 4 .

[0031] It should be noted that, in this embodiment, preferably, two openings 5 ​​are provided on the deformable part 3, the end of the deformable part 3 close to the sleeve 1 is a fixed end, and the end of the deformable part 3 away from the sleeve 1 is a free end. After the nail body 2 is nailed into the inner cavity of the sleeve 1, the free end is opened under the support of the nail body 2, and the deformable part 3 to be connected is anchored and connected with the part to be connected through the expanded deformable part 3. The nail body 2 adopts a structure that is directly nailed into the inside of the sleeve 1, rather than the existing threaded rod structure that needs to be screwed into the inside of the sleeve 1. The nailing of the nail body 2 improves the installation efficiency compared with the screwing of the bolt rod in the prior art. In addition, in the prior art, the screw-in thermal insulation anchor bolt adopts a long strip gap with closed ends on the deformable part 3. The opening of the long strip gap has certain limitations on the expansion of the deformable part 3. The utility model directly provides an opening 5 from the end of the deformable part 3 to the sleeve 1, so that the end of the deformable part 3 away from the sleeve 1 forms a free end. Such a configuration can improve the expansion degree of the deformable part 3. In this embodiment, the part to be connected is a composite wall panel, which is composed of a fireproof layer, a polyurethane layer and an autoclaved aerated concrete panel arranged in sequence. The easily deformable portion 3 of the penetration-type fastening anchor penetrates from the surface of the fireproof layer, passes through the polyurethane layer and extends into the interior of the autoclaved aerated concrete panel. The easily deformable portion 3 is anchored to the interior of the autoclaved aerated concrete panel to improve the firmness of the connection of the composite wall panel.

[0032] In a further embodiment, the easily deformable portion 3 is integrally formed with the sleeve 1. The integrally formed easily deformable portion 3 and sleeve 1 can improve the overall strength of the penetration-type fastening anchor bolt. Specifically, the easily deformable portion 3 and sleeve 1 are integrally injection-molded plastic parts. In other embodiments, they can also be made of materials such as stainless steel.

[0033] In a further embodiment, the anti-slip structure 4 is a barb structure. Specifically, a plurality of barb rings spaced apart from each other are arranged on the outer surface of the deformable portion 3 along the axial direction of the deformable portion 3. After the deformable portion 3 expands, the barb structure is used to improve the anchoring ability. In other embodiments, the barb structure can also be arranged as a plurality of raised columns or other structures.

[0034] In a further embodiment, a pressure plate 6 is further included, which is connected to one end of the sleeve 1 away from the easily deformable portion 3, and is provided with a through hole coaxially arranged with the inner cavity of the sleeve 1. The pressure plate 6 can play a limiting role.

[0035] In a further embodiment, the through hole is a stepped hole, and the stepped hole is used to cooperate with the nail cap of the nail body 2 so that the nail cap sinks into the stepped hole. The provision of the stepped hole can ensure that after the nail body 2 is nailed in, the nail cap sinks into the stepped hole, thereby ensuring the flatness of the outer surface of the composite wallboard and improving the aesthetics of the composite wallboard.

[0036] In a further embodiment, preferably, the pressure plate 6 is a disc structure, and the pressure plate 6 is coaxially arranged with the sleeve 1. Specifically, a plurality of through holes may be arranged on the pressure plate 6, and the plurality of through holes are arranged in a circular array with the axis of the pressure plate 6, so that the through holes on the pressure plate 6 are in a petal-shaped structure.

[0037] In a further embodiment, the outer diameter of the easily deformable portion 3 is slightly larger than the outer diameter of the sleeve 1. It is sufficient as long as the outer diameter of the easily deformable portion 3 is smaller than the diameter of the drilled hole in the composite wallboard.

[0038] In a further embodiment, the end of the inner cavity of the easily deformable portion 3 close to the sleeve 1 is a tapered hole with the tip facing the easily deformable portion 3. By providing a tapered hole at one end of the inner cavity of the easily deformable portion 3 close to the pressure plate 6, the setting of the tapered hole has a guiding effect on the nail body 2 being driven in, and at the same time, since the cylindrical surface of the nail body 2 gradually contacts the inner wall of the tapered hole, the easily deformable portion 3 is gradually expanded as the nail body 2 is driven in.

[0039] In this specification, each embodiment is described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be referred to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the method part.

[0040] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
