[0010] 3. The utility model provides a heat-insulating connector with a first side edge and a second side edge, which is also helpful in reducing the occupied space, especially reducing the space occupied by curtain wall columns and decorative strips, and helping to reduce the impact on the layout and installation of panels and decorative strips.

[0011] 4. The utility model provides a mounting seat, and directly connects metal profiles such as curtain wall columns without a heat-insulating connector, which can simplify the appearance of the heat-insulating connector and reduce manufacturing difficulty and production cost.

[0012] 5. The utility model can provide a suitable installation structure according to the form of the curtain wall column by providing a mounting seat, and then select different combinations of mounting seats and thermal insulation connectors to meet installation needs, reduce installation difficulty, and facilitate popularization and application.

[0013] 6. The utility model can also reduce the processing of the thermal insulation connector and the damage to the thermal insulation connector by providing the mounting seat, which helps to maintain the integrity of the thermal insulation connector.

[0014] According to the decorative strip connecting device of the first aspect of the present utility model, the thermal insulation connecting piece is in a plate shape.

[0015] Advantageously, the utility model makes the heat insulating connector plate-shaped, which, on the one hand, makes the heat insulating connector have sufficient strength to withstand the gravity pull in the indoor and outdoor directions, and on the other hand, minimizes the occupied space along the wall direction without affecting the arrangement of the panel and decorative strips.

[0016] According to the decorative strip connecting device of the first aspect of the embodiment of the utility model, the thermal insulation connecting piece includes a glass fiber reinforced composite material.

[0017] Advantageously, the utility model can enhance the thermal insulation effect by using glass fiber reinforced composite materials to manufacture the thermal insulation connector, and at the same time, improve the strength of the thermal insulation connector, facilitate the bearing of heavier decorative parts, and reduce restrictions on curtain wall applications.

[0018] According to the decorative strip connecting device of the first aspect of the present invention, the thermal insulation connecting member includes a profile, and the first side and the second side are distributed along the extrusion direction of the profile.

[0019] The benefit is that: the utility model uses profiles to manufacture the insulating connector, which can not only reduce the manufacturing difficulty, but also make it convenient to change the outer dimensions of the insulating connector through cutting, which is convenient for application in different usage scenarios. For example, the distance between the first side edge and the second side edge can be determined by cutting to be suitable for curtain walls of different thicknesses. At the same time, there is no need to add molds, thereby reducing production costs.

[0020] According to the decorative strip connecting device of the first aspect of the present invention, the mounting seat has a first notch for accommodating the second side edge, and the side wall of the first notch is provided with a first bolt, which passes through the second side edge and fixes the second side edge.

[0021] Advantageously, the utility model provides a first notch to facilitate the accommodation and positioning of the second side edge, thereby reducing the deflection of the thermal insulation connector along the wall surface, thereby helping to resist wind force along the wall surface and reducing the shaking of the decorative strip.

[0022] At the same time, the utility model sets a first bolt, and the first bolt passes through the second side edge. Therefore, the first bolt limits and fixes the thermal insulation connector by the physical interference between the screw rod and the second side edge, which can increase the connection strength, overcome the weight of the decorative strip and the thermal insulation connector, and meet the load-bearing requirements.

[0023] At the same time, the first bolt can also bring the two opposite side walls of the first notch closer together, thereby allowing the first notch to clamp the second side edge, further improving the limiting and fixing effects.

[0024] At the same time, even if the first bolt is loose, since the main force direction of the first bolt is perpendicular to the axial direction of the first bolt, it will less affect the connection between the mounting seat and the thermal insulation connector, and the problem of falling off rarely occurs.

[0025] According to the decorative strip connecting device of the first embodiment of the utility model, the number of the heat insulating connecting members is two or more, and the two or more plate-shaped heat insulating connecting members are stacked in the first notch.

[0026] Advantageously, the utility model can increase the overall shape of the thermal insulation connector by providing two or more plate-shaped thermal insulation connectors, without adding a single thicker thermal insulation connector, thereby reducing the difficulty of production and manufacturing, and at the same time, meeting the needs of installation and load-bearing.

[0027] According to the decorative strip connecting device of the first aspect of the present invention, the mounting seat has two second notches for mounting and fixing, the two second notches are arranged back to back, and the two second notches are used for plugging and fixing.

[0028] Advantageously, the utility model provides two second notches so that both sides of the mounting base along the wall surface can be plugged into the columns of the curtain wall, thereby improving the connection strength between the mounting base and the column, reducing the use of screws, and simplifying installation.

[0029] According to the decorative strip connecting device of the first aspect of the present invention, the mounting seat has a side for forming the second notch, and the side is provided with a second bolt for installation and fixing.

[0030] The benefit is that: the utility model arranges the second bolt on the side, so that the side fits with the curtain wall column and improves the sealing. At the same time, the second bolt presses the side against the curtain wall column. When bearing, the side and the second bolt are subjected to force at the same time, which can improve the connection strength and help to bear heavier decorative strips.

[0031] At the same time, since the second notch and the part of the curtain wall column form an inward and outward staggered direction, it has a limiting effect. Even if the second bolt occasionally loosens, the mounting base can still maintain connection with the curtain wall column, reducing the risk of falling off.

[0032] A curtain wall according to an embodiment of the second aspect of the utility model includes a decorative strip and also includes any one of the decorative strip connecting devices.

[0033] The curtain wall according to the embodiment of the utility model has at least the following beneficial effects:

[0034] The utility model can meet the installation requirements of the decorative strips and reduce heat transfer at the decorative strips by applying the decorative strip connection device, which is beneficial to energy saving and helps to produce and manufacture curtain walls or buildings that can meet ultra-low energy consumption requirements.

[0035] At the same time, the characteristics of the connection device also help reduce the production and manufacturing costs of curtain wall manufacturers and the difficulty of assembly at the installation site.

[0036] According to a curtain wall of an embodiment of the second aspect of the utility model, the curtain wall includes a column, and the column has a semi-enclosed groove, and the semi-enclosed groove is used to install the mounting seat.

[0037] Advantageously, the utility model provides a semi-enclosed groove, so that a part of the mounting seat can be accommodated in the semi-enclosed groove, thereby generating physical interference, reducing the risk of separation, and reducing the reliance on screws.

[0038] At the same time, the semi-enclosed groove can also be used for the installation and fixation of structures such as curtain wall panels, reducing the structural changes to the columns and facilitating promotion and application.

[0039] According to a curtain wall of an embodiment of the second aspect of the utility model, the notch of the semi-enclosed groove is provided with a convex edge, and the convex edge is used to abut the mounting seat.

[0040] The benefit is that: the utility model can, by setting a convex edge, on the one hand, enhance the strength of the notch of the semi-enclosed groove, reduce the deformation of the notch, and enhance the ability to fix the mounting seat; on the other hand, it is also convenient for strip threading and compounding, convenient for setting the structure of the fixed curtain wall panel, and reducing the types of columns.

[0041] According to a curtain wall of an embodiment of the second aspect of the utility model, the side edge is Z-shaped to accommodate the convex edge.

[0042] Advantageously, the utility model can avoid the convex edge and enhance the strength of the side edge by arranging the side edge into a Z shape, which helps to enhance the bearing capacity of the connecting device.

Therefore, the first bolt 6 limits and fixes the thermal insulation connector 1 by the physical interference between the screw rod and the second side edge 3, which can increase the connection strength, overcome the weight of the decorative strip and the thermal insulation connector 1, and meet the load-bearing requirements.

[0078] At the same time, the first bolt 6 can also bring the two opposite side walls of the first notch 5 closer together, thereby allowing the first notch 5 to clamp the second side edge 3, further improving the limiting and fixing effects.

[0079] At the same time, even if the first bolt 6 is loose, since the main force direction of the first bolt 6 is perpendicular to the axial direction of the first bolt 6, it will less affect the connection between the mounting seat 4 and the thermal insulation connector 1, and the problem of falling off rarely occurs.
