Technical Field
[0001] This utility model relates to the field of building installation fastener technology, and in particular to a metal nail for fixing wall insulation layers. Background Technology
[0002] In colder regions, insulation layers are typically installed on the exterior walls of buildings. These layers are usually secured with nails. Metal nails have thinner shafts, resulting in lower stability when securing the insulation. Therefore, a larger number of nails are needed for the same area of insulation, increasing costs. Alternatively, cheaper plastic nails are used. Plastic nails have thicker shafts, providing better stability when securing the insulation, but they pose a flammable safety hazard. To address this issue, metal nail sleeves are used to encase metal nails for better securing of the insulation.
[0003] For example, patent application CN202121480986.9 discloses a metal nail for fixing a wall insulation layer, comprising a metal nail sleeve body, a fixing plate located at one end of the nail sleeve body with a central hole therein, an axial through hole coaxial with the central hole within the nail sleeve body, a guide member within the axial through hole, and an axial hole within the guide member for the tip of the nail to pass through and for accommodating the nail shaft, the axial hole being coaxial with the axial through hole; the guide member is made of a poor conductor of heat. Compared to ordinary metal nails, the use of a guide member made of a poor conductor of heat prevents direct contact between the metal nail and the metal nail sleeve body, thus preventing heat exchange between the wall and the outside environment through the nail and nail sleeve body, which would result in poor insulation performance.
[0004] Based on the above search and analysis of existing technologies, it has been found that existing metal nail sleeves similar to those disclosed above merely enlarge the portion of the nail that contacts the insulation layer; the portion connecting the nail to the base wall remains thin, resulting in unreliable fixing. Therefore, a metal nail for fixing wall insulation layers is proposed to improve upon these issues. Utility Model Content
[0005] The purpose of this application is to provide a metal nail for fixing a wall insulation layer, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this application provides the following technical solution: a metal nail for fixing a wall insulation layer, comprising a metal nail rod and an integrally disposed metal nail head on the side of the metal nail rod away from its tip;
[0007] A metal sleeve is fitted on the outside of the metal nail rod;
[0008] The end of the metal sleeve away from the metal nail head is configured with a pointed tip shape that matches the tip of the metal nail shank;
[0009] A heat-insulating sleeve is provided between the metal sleeve and the metal nail rod;
[0010] The heat insulation sleeve is fixed to the metal sleeve, and the heat insulation sleeve is detachably connected to the metal nail rod.
[0011] Preferably, the inner wall of the heat insulation sleeve is provided with a thread;
[0012] The surface of the metal nail rod is provided with a second thread that matches the first thread.
[0013] Preferably, a limiting protrusion is provided on the inner wall of the middle portion of the metal sleeve;
[0014] The outer wall of the middle part of the heat insulation sleeve is provided with a limiting groove that matches the limiting protrusion.
[0015] Preferably, a heat-insulating washer is fixedly connected to the end face of the metal nail head near the metal nail rod;
[0016] The end of the metal sleeve near the metal nail head is fixedly connected to a metal ring that abuts against the heat insulation washer.
[0017] Preferably, a fireproof ring is fixedly connected to the metal nail cap near the end face edge of the metal nail rod;
[0018] The fireproof ring is fitted onto the outside of the heat insulation gasket, and the diameter of the metal ring is not greater than the diameter of the heat insulation gasket.
[0019] Preferably, the heat insulation gasket is provided with an annular groove that is adapted to the metal ring.
[0020] In summary, the technical effects and advantages of this utility model are as follows:
[0021] 1. In this utility model, by setting the end of the metal sleeve away from the metal nail head to a pointed shape that matches the nail tip of the metal nail rod, the metal sleeve and the metal nail rod are assembled into a new nail. The new nail can be driven into the insulation layer and the foundation wall in the existing nailing method. Moreover, the overall nail rod of the new nail is thicker, and the fixing effect is more stable and reliable. By setting a heat insulation sleeve between the metal sleeve and the metal nail rod, direct contact between the metal nail rod and the metal sleeve can be avoided, thereby effectively blocking the heat exchange between the indoor and outdoor areas and improving the heat insulation effect of the insulation layer.
[0022] 2. In this utility model, the metal ring and the metal nail head are separated by a heat-insulating gasket, which can effectively prevent direct heat conduction between the metal ring and the metal nail head. The fireproof ring is placed on the outside of the heat-insulating gasket, which can effectively prevent the heat-insulating gasket from burning. The diameter of the metal ring is not greater than the diameter of the heat-insulating gasket, so as to avoid heat conduction caused by contact between the metal ring and the fireproof ring.

[0030] 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.
[0031] Example: Reference Figure 1-5 The metal nail shown is used for fixing a wall insulation layer. It includes a metal nail rod 1 and a metal nail head 2 integrally disposed on the side of the metal nail rod 1 away from its tip. A metal sleeve 4 is sleeved on the outside of the metal nail rod 1.
[0032] The end of the metal sleeve 4 away from the metal nail head 2 is set with a pointed tip shape that matches the nail tip of the metal nail rod 1. A heat insulation sleeve 3 is provided between the metal sleeve 4 and the metal nail rod 1. The heat insulation sleeve 3 can be made of a poor conductor of heat, such as common and readily available plastic, which is low in cost and has good heat insulation effect.
[0033] The heat insulation sleeve 3 is fixed to the metal sleeve 4. Specifically, for example, a limiting protrusion 41 is provided on the inner wall of the middle part of the metal sleeve 4, and a limiting groove 32 that matches the limiting protrusion 41 is provided on the outer wall of the middle part of the heat insulation sleeve 3. The heat insulation sleeve 3 and the metal sleeve 4 are relatively fixed by the cooperation of the limiting protrusion 41 and the limiting groove 32, so as to prevent relative rotation and separation between the heat insulation sleeve 3 and the metal sleeve 4.
[0034] The heat insulation sleeve 3 and the metal nail rod 1 are detachably connected. Specifically, for example, a thread 31 is provided on the inner wall of the heat insulation sleeve 3, and a thread 11 that matches the thread 31 is provided on the surface of the metal nail rod 1. The heat insulation sleeve 3 and the metal nail rod 1 are connected by the cooperation of the thread 31 and the thread 11, which facilitates disassembly and assembly.
[0035] By setting the end of the metal sleeve 4 away from the metal nail head 2 to a pointed shape that matches the tip of the metal nail shank 1, the metal sleeve 4 and the metal nail shank 1 are assembled as follows: Figure 1 When the state shown is reached, a new nail is formed. The new nail can be driven into the insulation layer and the base wall in the existing nailing method. The overall nail rod of the new nail is thicker, and the fixing effect is more stable and reliable. By setting a heat insulation sleeve 3 between the metal sleeve 4 and the metal nail rod 1, direct contact between the metal nail rod 1 and the metal sleeve 4 can be avoided, thereby effectively blocking the heat exchange between the indoor and outdoor areas and improving the heat insulation effect of the insulation layer.
[0036] Among them, a heat-insulating washer 5 is fixedly connected to the end face of the metal nail head 2 near the metal nail rod 1. The heat-insulating washer 5 can also be made of a poor conductor of heat, such as common and readily available plastic, which is low in cost and has a good heat insulation effect. A metal ring 7 that abuts against the heat-insulating washer 5 is fixedly connected to the end of the metal sleeve 4 near the metal nail head 2. The metal ring 7 can increase the support of the metal nail head 2. When nailing, the metal nail head 2 is not easily deformed. The metal ring 7 and the metal nail head 2 are separated by the heat-insulating washer 5, which can effectively prevent direct heat conduction between the metal ring 7 and the metal nail head 2.
[0037] Furthermore, a fireproof ring 6 is fixedly connected to the edge of the metal nail head 2 near the end face of the metal nail rod 1. The fireproof ring 6 is sleeved on the outside of the heat insulation gasket 5. In the installed state, the fireproof ring 6 blocks the outside of the heat insulation gasket 5, which can effectively prevent the heat insulation gasket 5 from burning. The diameter of the metal ring 7 is not greater than the diameter of the heat insulation gasket 5 to avoid heat conduction caused by the metal ring 7 contacting the fireproof ring 6.
[0038] Furthermore, the heat insulation gasket 5 is provided with an annular groove that matches the metal ring 7. In the installed state, the metal ring 7 is embedded in the annular groove on the heat insulation gasket 5, ensuring that the heat insulation gasket 5 can fit the insulation layer.
[0039] The working principle of this utility model is as follows: The metal sleeve 4 and the metal nail rod 1 are assembled as shown in the figure. Figure 1 In the state shown, a new nail is formed, which can be driven into the insulation layer and the foundation wall using the existing nailing method. The new nail has a thicker overall shank, resulting in a more stable and reliable fixation. By setting a heat-insulating sleeve 3 between the metal sleeve 4 and the metal nail shank 1, direct contact between the metal nail shank 1 and the metal sleeve 4 is avoided, effectively blocking heat exchange between the indoor and outdoor areas and improving the insulation effect of the insulation layer. In the installed state, the metal ring 7 and the metal nail head 2 are separated by a heat-insulating washer 5, effectively preventing metal from... The direct heat conduction between the metal ring 7 and the metal nail head 2 is achieved by the fireproof ring 6 blocking the outside of the heat insulation gasket 5, which can effectively prevent the heat insulation gasket 5 from burning. The diameter of the metal ring 7 is not greater than the diameter of the heat insulation gasket 5 to avoid heat conduction caused by contact between the metal ring 7 and the fireproof ring 6. In the installed state, the metal ring 7 is embedded in the annular groove on the heat insulation gasket 5 to ensure that the heat insulation gasket 5 can fit the insulation layer. The heat insulation sleeve 3 and the metal nail rod 1 are connected by threaded connection 31 and thread 11, which facilitates disassembly and assembly.
