Description

Technical Field

[0001] The present application relates to the technical field of house construction, and in particular to a self-drilling thermal insulation wall repair connector. Background Art

[0002] Insulation wall repair connector technology is a technology used to repair and connect insulation walls. With the development of the construction industry, insulation walls are increasingly used in buildings. Insulation walls include a wall body and an insulation layer, and the insulation layer is attached to the outside of the wall body by pasting. However, due to aging and other reasons, cavities are prone to appear between insulation walls, and even the insulation layer is prone to fall off.

[0003] In the traditional insulation wall repair process, it is usually necessary to remove the damaged or broken insulation wall, remake and install a new insulation wall. This method is not only time-consuming and labor-intensive, but also requires a lot of material and labor costs. Therefore, in order to solve this problem, some insulation wall repair connector technologies have been developed.

[0004] Most of the existing repair connectors are made of engineering plastic insulation nails or engineering plastic sleeve metal insulation nails. However, during use, the engineering plastics and metals in the above two types of insulation nails are not corrosion-resistant. Aging of engineering plastics and rust of metals can easily lead to loss of pull-out resistance, affecting the repair connection of the insulation wall. Utility Model Content

[0010] By adopting the above technical solution, the thermal conductivity of the metal screw and the metal tail plate can be reduced by utilizing the thermal insulation layer, thereby reducing the impact on the thermal insulation function of the thermal insulation wall.

[0011] Preferably, the end of the screw rod away from the tail disc is set to a forward drilling angle.

[0028] The following is combined with Figure 1-3 This application is described in further detail.

[0029] An embodiment of the present application discloses a self-drilling thermal insulation wall repair connector.

[0030] Reference Figure 1 , Figure 2 and Figure 3 A self-drilling insulation wall repair connector includes a screw rod 2, and a tail plate 1 is provided at one end of the screw rod 2 in the length direction. When installing the insulation wall repair connector, firstly, a mounting hole 104 is opened on the vertical wall surface of the insulation wall, and the mounting hole 104 is opened through the insulation layer 102; then an appropriate amount of anchor glue or anchoring agent is injected into the mounting hole 104, and then the end of the screw rod 2 away from the tail plate 1 is inserted into the mounting hole 104 until the tail plate 1 abuts against the outside of the insulation layer 102, and finally a plaster layer 103 is provided on the outside of the insulation side to complete the installation of the insulation wall repair connector. In this embodiment, the screw rod 2 and the tail plate 1 are made of corrosion-resistant metal, such as stainless steel, so as to improve corrosion resistance and durability.

[0031] The tail plate 1 is in the shape of a circular plate as a whole, and the center of the tail plate 1 is on the axis of the screw 2. The tail plate 1 is fixedly connected to the screw 2 by welding or riveting, so that the bearing capacity of the tail plate 1 can be improved. A mounting hole 104 is provided on the side of the tail plate 1 away from the screw 2. The mounting hole 104 is slotted in the direction away from the screw 2. The connector can be installed on the insulation wall with a wrench or an electric drill, and the tail plate 1 also plays a limiting role. The center of the bottom of the mounting hole 104 coincides with the axis of the screw 2. When tightening the connector, the torque acting on the connector is more uniform, avoiding damage or loosening of the connector caused by uneven torque. In this embodiment, the mounting hole 104 is set as a hexagonal slot, which is convenient to use, so that the matching wrench can tighten the connector conveniently and quickly, improving work efficiency. A plurality of penetration holes 12 are also provided on the tail plate 1. The plurality of penetration holes 12 are opened along the circumference of the tail plate 1, which can increase the permeability of the concrete and effectively increase the strength of the plaster layer 103.

[0032] The end of the screw rod 2 away from the tail plate 1 is provided with a forward drilling angle 21, which can effectively stir the anchor glue or anchoring agent to save effort when installing the product. In addition, the end of the screw rod 2 away from the tail plate 1 is also provided with a resistance thread 22, the threaded portion of which has a diameter greater than the diameter of the screw rod 2, and the concave and convex portion of the thread can increase the resistance, so that the anchor glue or anchoring agent in the installation hole 104 can be more uniform when the screw rod 2 is installed.

[0033] However, since the thermal conductivity of metal is high, it is easy to affect the thermal insulation performance of the insulation wall. Therefore, the outer side of the tail plate 1 and the screw 2 near the end of the tail plate 1 is formed with an insulation layer 3 through an injection molding process. In this embodiment, the insulation layer 3 is made of corrosion-resistant engineering plastics, which can reduce the thermal conductivity of the insulation wall repair connector while having corrosion resistance. And the insulation layer 3 formed by injection molding is wrapped around the connection between the tail plate 1 and the screw 2, so that the screw 2 and the tail plate 1 are compositely integrated, thereby further improving the bearing capacity of the tail plate 1.

[0034] The heat-insulating layer 3 on the screw 2 is integrally formed with a stopper thread 4 on the outer side away from the screw 2, that is, the stopper thread 4 is located at the end of the screw 2 close to the tail plate 1, and the diameter of the threaded portion of the stopper thread 4 is greater than the diameter of the threaded portion of the resistance thread 22. When the connector is installed on the insulation wall, the stopper thread 4 is located in the insulation layer 102, and when the connector is installed, a tighter combination can be formed between the connector and the insulation layer 102, so as to solve the overflow of the anchor glue or anchoring agent as much as possible, effectively increase the liquid saturation, and reduce the occurrence of hollowing.

[0035] The implementation principle of a self-drilling insulation wall repair connector in an embodiment of the present application is as follows: by using a tail plate 1 and a screw 2 made of corrosion-resistant metal, and a thermal insulation layer 3 formed of corrosion-resistant engineering plastic, the corrosion resistance of the connector is improved while ensuring that the insulation performance of the insulation wall is not affected; the forward drilling angle 21 and the resistance thread 22 are used to improve the anchoring force, and the stop thread 4 can reduce the overflow of the rebar glue or anchoring agent.

[0036] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
