Description

Technical Field

[0001] The utility model relates to the technical field of wall connection component manufacturing, in particular to a wall external insulation layer connection piece. Background Art

[0002] Insulation layer connectors are devices used to connect buildings and insulation layers to prevent buildings from falling off. They have high tensile, shear and bending strength, large elastic modulus, good durability, excellent alkali resistance, and extremely low thermal conductivity. Insulation layer connectors generally refer to components that strengthen the stability of other structures by connecting to reliable fixed ends. In construction projects, they are used to connect the exterior wall insulation layer to the main structure of the building. They are components that can transmit tension and pressure. The wall connection achieved by connectors improves the overall stability of the insulation layer. The connecting rod plays an important role in interlacing and connecting, improving the firmness between the building and the insulation layer. With the continuous development of science and technology, people have higher and higher requirements for the manufacturing process of insulation layer connectors. In the past construction of prefabricated concrete wall panels, the outer insulation layer was connected to the base wall by driving insulation nails into the base wall. However, due to the high heat transfer coefficient of traditional metal insulation connectors, thermal bridge effects are easily generated, and horizontally driven insulation nails have poor shear resistance. In addition, the insulation layer and the decorative layer are connected to the base wall through insulation nails. When prefabricated wall panels are used as exterior wall parts, although the insulation layer can resist repeated alternations of hot and cold outside, long-term temperature changes will cause thermal expansion and contraction of the insulation layer, and cracks will appear in the insulation layer of the prefabricated wall panels, leading to common quality problems such as external insulation falling off.

[0025] Example

[0026] Please refer to Figure 1 and Figure 2 , Figure 1 Shown is a schematic structural diagram of an embodiment of the utility model; Figure 2 Schematic diagram of the installation structure of an embodiment of the utility model. This embodiment provides a wall external insulation layer 6 connector, including an anchoring beam 1 and two rib arms 2, the anchoring beam 1 is a U-shaped structure, and the two rib arms 2 are parallel and symmetrically arranged on the two limbs of the anchoring beam 1. The anchoring beam 1 is used to fix the insulation layer 6, and the two rib arms 2 are used to extend into the wall. The anchoring beam 1 adopts a U-shaped structure to connect the two rib arms 2, and the two rib arms 2 are fixed to improve the stabilization effect.

[0027] Any of the above-mentioned rib arms 2 is a lotus root-shaped structure, and the above-mentioned rib arms 2 are fiber-reinforced composite materials. The above-mentioned rib arms 2 adopt a lotus root-shaped structure to enhance the structural stability of the rib arms 2. At the same time, the lotus root-shaped structure can increase the contact area with the wall, thereby greatly increasing the connection stability between the rib arms 2 and the wall. Finally, the lotus root-shaped structure can effectively avoid the problem of thermal expansion and contraction. When the temperature difference is large during the alternation of hot and cold, the thermal expansion and contraction of the lotus root-shaped structure will be reflected at the lotus root as an anti-expansion joint, which plays a role in absorbing the deformation of the rib arms 2, thereby effectively preventing the thermal expansion and contraction of the insulation layer 6 caused by long-term temperature changes, and cracks will appear in the prefabricated wallboard insulation layer 6, leading to problems such as external insulation falling off. The above-mentioned rib arms 2 adopt a fiber-reinforced composite material, which can also enhance the stability of the rib arms 2 themselves, and can also further resist the above-mentioned deformation problems caused by thermal expansion and contraction.

[0028] Therefore, the wall external insulation layer 6 connector can firmly fix the insulation layer 6 on the wall, preventing the connector from falling off due to thermal expansion and contraction, and greatly improving the connection stability of the insulation layer 6 on the wall.

[0029] In some implementations of this embodiment, a connecting arm 8 is provided between any of the rib arms 2 and the anchoring beam 1 , and one end of the connecting arm 8 is connected to the anchoring beam 1 , and the other end is connected to the rib arm 2 .

[0030] In this embodiment, the connecting arm 8 is used to connect the anchoring beam 1 and the rib arm 2, so as to increase the depth of the rib arm 2 extending into the wall.

[0031] In some implementations of this embodiment, the cross section of the connecting arm 8 is a circular structure. In this embodiment, the cross section of the connecting arm 8 is a circular structure, which can increase the contact area between the connecting arm 8 and the wall.

[0032] In some implementations of this embodiment, the cross section of the connecting arm 8 is an elliptical structure. In this embodiment, the connecting arm 8 with an elliptical cross section can also increase the contact area between the connecting arm 8 and the wall.

[0033] In some implementations of this embodiment, the connecting arm 8 and the corresponding rib arm 2 are integrally formed. In this embodiment, the connecting arm 8 and the corresponding rib arm 2 are integrally formed. The integral forming process is mainly used in the manufacturing industry, which means that a certain part is made in one process without the need for secondary or higher processing. The manufacturing of a certain part is completed in one process in the whole process. Integral forming and non-integral forming are two different manufacturing processes. The manufactured product or part is a whole without any connection. Compared with non-integral forming, it has higher quality and longer service life.

[0034] In some implementations of the present embodiment, a transverse hole 3 is formed on any of the rib arms 2 , and a limiting pin 9 is passed through the transverse hole 3 .

[0035] In this embodiment, the transverse hole 3 can play a limiting role. After the limiting pin 9 is inserted into the transverse hole 3, it can further limit the axial direction of the rib arm 2, so that the rib arm 2 can be more firmly connected to the wall. It should be noted that in some implementations of this embodiment, the transverse holes 3 on the two rib arms 2 are coaxial, and the two transverse holes 3 can share one limiting pin 9.

[0036] In some implementations of this embodiment, the fiber-reinforced composite material includes a glass fiber-reinforced composite material. The glass fiber-reinforced composite material has a small coefficient of thermal expansion and contraction, which can reduce the deformation of the rib arm 2 when the thermal expansion and contraction effect occurs, and can further avoid the above-mentioned problem of falling off due to thermal expansion and contraction.

[0037] In some implementations of this embodiment, the fiber-reinforced composite material includes a basalt fiber-reinforced composite material. The basalt fiber-reinforced composite material is an existing material, which is a new type of inorganic environmentally friendly green high-performance fiber material, which is composed of oxides such as silicon dioxide, aluminum oxide, calcium oxide, magnesium oxide, iron oxide and titanium dioxide. Basalt continuous fiber is not only high in strength, but also has many excellent properties such as electrical insulation, corrosion resistance, and high temperature resistance. The basalt fiber-reinforced composite material has a small thermal expansion and contraction coefficient. When the thermal expansion and contraction effect occurs, the deformation of the rib arm 2 can be reduced, which can further avoid the above-mentioned problem of falling off due to thermal expansion and contraction.

[0038] In some implementations of this embodiment, the fiber-reinforced composite material includes a carbon fiber-reinforced composite material. The carbon fiber-reinforced composite material is an existing material, which is mainly composed of carbon elements, has the characteristics of high temperature resistance, friction resistance, heat conduction and corrosion resistance, and is fibrous, soft, and can be processed into various fabrics. Because its graphite microcrystalline structure is preferentially oriented along the fiber axis, it has high strength and modulus along the fiber axis. The density of the carbon fiber-reinforced composite material is small, so the specific strength and specific modulus are high. The main purpose of the carbon fiber-reinforced composite material is to be used as a reinforcing material for compounding with resins, metals, ceramics and carbon to manufacture advanced fiber-reinforced composite materials. The carbon fiber-reinforced composite material also has the characteristics of a small coefficient of thermal expansion and contraction. When the thermal expansion and contraction effect occurs, the deformation of the rib arm 2 can be made smaller, which can further avoid the above-mentioned problem of falling off due to thermal expansion and contraction.

[0039] It should be noted that, in the present embodiment, the above-mentioned anchoring beam 1 and the connecting arm 8 also adopt the above-mentioned fiber-reinforced composite material to further resist thermal expansion and contraction, while improving the stability of the anchoring beam 1 and the connecting arm 8 themselves.

[0040] When in use, the base wall 7 is cast in the formwork, and then holes are punched on the insulation layer 6, and then the glass fiber mesh cloth 5 is laid on the insulation layer 6. Then the ribs 2 and the connecting walls are inserted into the holes on the insulation layer 6 in sequence through the glass fiber mesh cloth 5. Finally, the insulation layer 6 and the glass fiber mesh cloth 5 are placed as a whole on the unhardened base wall 7, so that the connecting wall and the ribs 2 are deeply embedded in the base wall 7. At this time, the anchor beam 1 will fix the insulation layer 6 on the wall. Finally, the polymer cement mortar layer 4 is applied to the upper surface of the insulation layer 6, and the wall and the cement mortar layer are left to dry.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
