Description

Technical Field

[0001] The invention relates to the technical field of building curtain walls, in particular to a building curtain wall system. Background Art

[0002] At present, the splicing between two adjacent panels of the prefabricated building curtain wall unit system is achieved through a plug-in connection structure. This plug-in connection method is a rigid connection method. After the construction and installation are completed, one or several panels cannot be removed separately. When the building function requires that several panels at certain locations on the building curtain wall be removed separately to achieve operations such as the transportation of building instruments and equipment, this traditional connection method is not applicable.

[0003] Moreover, this traditional plug-in connection method has a single construction and installation sequence, and can only be installed in one direction in sequence. When the project construction organization planning requires skipping construction and installation, that is, when it is impossible to install in sequence, this traditional connection method cannot meet the requirements, which greatly limits the construction organization planning.

[0004] To solve the problem of plug-in connection, a common method is to reserve a certain width of gap between two adjacent panels during construction and installation, and fill the gap with sealant to achieve sealing. However, this method belongs to the category of wet work, and its construction quality depends on the quality of the construction process, and the quality control of the project is somewhat difficult. If the quality of the caulking construction is not good, the air tightness and water tightness are poor, it is easy to cause water leakage in the exterior wall. Summary of the invention

[0033] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present invention and to enable the scope of the present invention to be fully communicated to those skilled in the art.

[0034] like Figure 1 As shown, an embodiment of the present invention provides a building curtain wall system, comprising:

[0035] A plurality of building curtain wall panels 1 arranged in sequence;

[0036] A curtain wall panel frame 2 surrounding the building curtain wall panel 1 and fixedly connected to the building curtain wall panel 1;

[0037] A sealing system 3 fixedly connected to the curtain wall panel frame 2, each of the curtain wall panel frames 2 is fixedly connected to a sealing system 3, the sealing system 3 is arranged between the transverse joints 61 or longitudinal joints 62 of the plurality of sequentially arranged building curtain wall panels 1, and each transverse joint 61 or longitudinal joint 62 includes two relatively arranged sealing systems 3.

[0038] In this embodiment, Figure 1 As shown, there are multiple transverse joints 61 and longitudinal joints 62 between the building curtain wall panels 1 arranged in sequence. In the present application, multiple sealing systems 3 are arranged at the positions of the transverse joints 61 and the longitudinal joints 62. The structural connection relationship between the sealing system 3 and the building curtain wall panels 1 is as shown in FIG. Figure 2 As shown, each sealing system 3 includes a plurality of soft elastic strips 31 arranged side by side, and the soft elastic strips 31 are fixedly connected to the end surface of the curtain wall panel frame 2. Between the upper and lower two adjacent building curtain wall panels 1 of a transverse joint 61, each building curtain wall panel 1 is connected to a transverse curtain wall panel frame 2. Between the upper and lower two adjacent curtain wall panel frames 2, a sealing system 3 is fixed on each curtain wall panel frame, and the upper and lower sealing systems 3 are arranged opposite to each other. When the upper and lower sealing systems 3 are closed, the transverse joint 61 is closed. Similarly, the longitudinal joint 62 can also be closed when the left and right two opposite sealing systems 3 are closed. Thereby, the building curtain wall panels 1 and the sealing system 3 realize a complete building climate boundary.

[0039] In an optional embodiment of the present invention, the sealing system 3 comprises:

[0040] A plurality of soft elastic rubber strips 31 clamped with the curtain wall panel frame 2, wherein the soft elastic rubber strips 31 include a first cavity;

[0041] A pressurized pipeline extending into the first cavity of the soft elastic rubber strip 31 and fixedly connected to the soft elastic rubber strip 31 .

[0042] In this embodiment, each sealing system 3 may include a plurality of soft elastic rubber strips 31 arranged side by side. Preferably, each sealing system 3 is provided with two soft elastic rubber strips 31. The soft elastic rubber strip 31 is a retractable structure having a first cavity. The pressurized pipeline extends into the first cavity, and the soft elastic rubber strip 31 can be inflated and pressurized or air can be sucked to form a negative pressure. Figure 3In the natural state shown, the pressurized pipeline is not inflated or inhaled, and the soft elastic strip 31 sags naturally. Figure 4 As shown, the first cavity of the soft elastic strip 31 is enlarged, the upper and lower corresponding sealing systems are fully in contact, and the transverse joints 61 between the building curtain wall panels 1 are closed. When the pressurized pipeline is inhaled by the soft elastic strip 31, as shown in FIG. Figure 5 As shown, negative pressure is formed inside the soft elastic strip 31, the volume of the first cavity is reduced, and the transverse joint 61 is completely opened. At this time, air circulates inside and outside the building, and natural ventilation can be achieved inside the building.

[0043] In an optional embodiment of the present invention, the pressurized pipeline comprises:

[0044] A plurality of pressurizing branches 321, wherein the pressurizing branches 321 extend into the first cavity of the soft elastic rubber strip 31 and are fixedly connected to the soft elastic rubber strip 31;

[0045] A pressurized main pipe 322 is fixedly connected to the plurality of pressurized branch pipes 321 , wherein a first end of the pressurized main pipe 322 is fixedly connected to the plurality of pressurized branch pipes 321 , and a second end of the pressurized main pipe 322 extends out of the curtain wall panel frame 2 .

[0046] The number of the pressurizing branch pipes 321 is equal to the number of the soft elastic rubber strips 31 , and each of the pressurizing branch pipes 321 is fixedly connected to a soft elastic rubber strip 31 .

[0047] In this embodiment, the pressurized pipeline is divided into a pressurized branch pipe 321 and a pressurized main pipe 322, which are connected at the curtain wall panel frame 2, and each pressurized branch pipe 321 is connected to a soft elastic rubber strip 31. The pressurized main pipe 322 extends from the end face of the curtain wall panel frame 2 into the cavity thereof, and extends from the indoor side wall of the curtain wall panel frame 2. When the soft elastic rubber strip 31 needs to be inflated or inhaled, the external pressurizing device inflates or inhales the soft elastic rubber strip 31 from the port of the pressurized main pipe 322 extending from the side wall of the curtain wall panel frame 2.

[0048] In an optional embodiment of the present invention, the end of the pressurizing branch pipe 321 is connected to an inflation valve 323 , and the inflation valve 323 is located in the first cavity of the soft elastic rubber strip 31 .

[0049] In this embodiment, the inflation valve 323 extends into the first cavity to control the opening and closing of the pressurizing branch pipe 321 .

[0050] In an optional embodiment of the present invention, the soft elastic rubber strip 31 includes a retractable structure 313 on the side wall in a natural state.

[0051] In this embodiment, the retractable structure 313 is in an accordion-like shape in a natural state. When the soft elastic rubber strip 31 is inflated, the retractable structure 313 in an accordion-like shape becomes smooth and the wrinkles disappear. The retractable structure 313 reserves sufficient deformation space for the expansion and retraction of the soft elastic rubber strip 31.

[0052] In an optional embodiment of the present invention, the first end of the soft elastic rubber strip 31 includes a first protrusion 311 , and the first protrusion 311 extends into the slot 21 of the curtain wall panel frame 2 .

[0053] In this embodiment, a slot 21 is provided at the end of the curtain wall panel frame 2, and the first protrusion 311 of the soft elastic rubber strip 31 is stuck in the slot 21, which is conducive to the sealing system 3 being stable and not easy to fall off.

[0054] In an optional embodiment of the present invention, the second end of the soft elastic rubber strip 31 includes a plurality of sawtooth grooves 312 , and the first end and the second end are arranged opposite to each other.

[0055] When the soft elastic rubber strip 31 of the sealing system 3 is in an inflated state, the serrated groove 312 is meshed with the serrated groove 312 of the soft elastic rubber strip 31 of the adjacent sealing system 3 .

[0056] In this embodiment, a serrated groove 312 is provided between the end faces of two adjacent soft elastic rubber strips 31. When the construction and installation of the building curtain wall panels are completed, the external pressurizing device performs an inflating and pressurizing operation on the soft elastic rubber strips 31. As the internal air pressure increases and the volume expands, the serrated grooves 312 of the two soft elastic rubber strips 31 are pressed together under the pressure to form a closed state. The serrated grooves 312 increase the contact surface between the soft elastic rubber strips 31, which is conducive to improving the sealing of the joints.

[0057] In an optional embodiment of the present invention, the curtain wall panel frame 2 is fixedly connected to the building concrete structure 4 via a curtain wall connecting piece 5 .

[0058] In this embodiment, the building curtain wall system is fixed to the building concrete structure 4 of the main structure of the building through the curtain wall connecting code 5, and the curtain wall connecting code 5 is bolted to the building curtain wall system and the building concrete structure 4.

[0059] The building curtain wall system of the present invention does not have a rigid plug-in connection mechanism, and the construction and installation of the building curtain wall panels 1 are not affected by the sequence, and the skipping method can be used for installation. After the construction project is put into operation, if a certain building curtain wall panel 1 needs to be dismantled separately according to the building function requirements, the external equipment vacuumizes the soft elastic rubber strip 31 to form a negative pressure, and the active control sealing system 3 is in a fully open state. At this time, the curtain wall connection code piece 5 of the corresponding building curtain wall panel 1 can be unlocked, and the corresponding building curtain wall panel 1 can be dismantled. Thereby, the separate disassembly of the building curtain wall panel 1 is realized without affecting the adjacent panels. The sealing performance of the building curtain wall system of the present invention is less affected by the quality of the on-site construction process and has high reliability; the opening and closing of the active control sealing system can be realized through the building management system.

[0060] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
