Description

Technical Field

[0001] The present invention relates to the field of building curtain walls, and in particular to an intelligent building curtain wall designed based on BIM. Background Art

[0002] With the development of the construction industry, people's requirements for the aesthetics, functionality and intelligence of buildings are increasing. As an important part of the building facade, the building curtain wall not only bears the function of the enclosure structure, but also plays a key role in the overall image of the building. The traditional building curtain wall design and construction process has many limitations, such as incomplete design information, difficulty in coordination among various disciplines, lack of precise guidance in the construction process, etc. These problems can easily lead to extended construction period, increased costs and difficulty in ensuring quality.

[0003] The emergence of BIM, or Building Information Modeling, has brought innovation to the construction industry. It uses three-dimensional digital models as a carrier to integrate various information from the entire process of building design, construction to operation and maintenance, and realizes a high degree of information sharing and collaborative work. Applying BIM technology to building curtain wall design can effectively solve the shortcomings of traditional design methods and realize the intelligent design and construction of building curtain walls.

[0004] At present, the connection between curtain wall panels and supporting structures mainly adopts two methods: adhesive bonding or component assembly. However, in actual projects, due to certain precision limitations in component processing technology, processing errors are inevitable. At the same time, during the assembly process, operations in various links will also introduce combination errors. These errors are constantly superimposed, making it difficult to ensure that the curtain wall panels and supporting structures achieve an ideal seamless state during the installation process. Summary of the invention

[0012] Furthermore, the stopping mechanism also includes an alignment component, which includes an infrared transmitter and an infrared receiver. An infrared receiver and an infrared transmitter are respectively provided on the side surfaces of two blocks at relative positions on both sides of the mounting frame. The infrared receiver and infrared transmitter are electrically connected to the controller. When the four groups of infrared transmitters and infrared receivers on the surrounding areas are aligned at the same time, the controller synchronously controls the electromagnets around the mounting frame to cut off power.

[0013] Furthermore, a filling component is provided in the slot portion, and the filling component is used to fill the gap between the building curtain wall and the slot portion to achieve sealing.

[0014] Further, the filling assembly includes an elastic filling strip and a pressing unit;

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1-Figure 4 As shown, the present invention is an intelligent building curtain wall based on BIM design, comprising: a controller and a mounting frame 1, on which the building curtain wall is fixed by a fixing mechanism 2, and the fixing mechanism 2 comprises:

[0031] A U-shaped block 21, wherein the blocks 21 are arranged in groups of two, and each group of two blocks 21 has a limited slide groove 22, and a limited slider 23 is slidably connected to the limited slide groove 22. A spiral groove 24 is provided on opposite sides of the two limited sliders 23, and the two spiral grooves 24 are arranged in opposite directions, and the two spiral grooves 24 are commonly spirally connected to the same bidirectional screw rod 25, and a rubber sleeve 26 is fixedly provided in the middle of the bidirectional screw rod 25;

[0032] The slot portion 27 is arranged around the mounting keel, and grooves 28 are fixedly provided on both side walls of the slot portion 27. The two sides of the two limit sliders 23 that are away from each other are provided with protrusions 29, and the grooves 28 cooperate with the protrusions 29.

[0033] The present invention places the building curtain wall on the installation frame 1, and then clamps the U-shaped clamping block 21 on the clamping groove portion 27 on the installation frame 1, and uses four groups of clamping blocks 21 distributed on the four sides of the building curtain wall to realize rapid fixation of the building curtain wall. During the initial installation, the clamping block 21 is kept roughly consistent with the clamping groove portion 27, and then the two-way screw rod 25 is driven to rotate by rotating the rubber sleeve 26, and the two-way screw rod 25 drives the two limit sliders 23 to move away synchronously until the protrusions 29 on the outer sides of the two limit sliders 23 just enter the corresponding grooves 28. At this time, the building curtain wall is quickly installed. If disassembly is required, the rubber sleeve 26 is rotated in the opposite direction to drive the two-way screw rod 25 to rotate, which is convenient and quick; at the same time, the position of the building curtain wall can also be quickly and conveniently adjusted.

[0034] A stop mechanism 3 is also provided on one side of the bidirectional screw rod 25, and the stop mechanism 3 is used to keep the bidirectional screw rod 25 stable and immobile after the building curtain wall is installed; the stop mechanism 3 includes:

[0035] The stop rod 31 is provided with two, and one end of the stop rod 31 is hingedly mounted on the middle part of the slot portion 27 through a torsion spring. A ring 32 is fixedly provided on the bidirectional screw rod 25, and a plurality of openings 33 are opened circumferentially on the ring 32, and the openings 33 are adapted to the stop rod 31. An iron block 34 is fixed on the free end of the stop rod 31, and an electromagnet 35 is embedded and connected at a corresponding position on the slot portion 27, and the electromagnet 35 is electrically connected to the controller.

[0036] The stopping mechanism 3 also includes an alignment component 36, which includes an infrared transmitter 361 and an infrared receiver 362. The infrared receiver 362 and the infrared transmitter 361 are respectively arranged on the side surfaces of the two blocks 21 at relative positions on both sides of the mounting frame 1. The infrared receiver 362 and the infrared transmitter 361 are electrically connected to the controller. When the four groups of infrared transmitters 361 and infrared receivers 362 on the surrounding areas are aligned at the same time, the controller synchronously controls the electromagnets 35 on the surrounding areas of the mounting frame 1 to cut off the power.

[0037] In the present invention, the cooperation between the electromagnet 35 and the stop rod 31 in the stop mechanism 3 ensures that the bidirectional screw rod 25 can be reliably stopped after the installation of the building curtain wall is completed. The electromagnetic force of the electromagnet 35 is sufficient to overcome the elastic force of the stop rod 31 and possible external interference forces, and the mechanical structure design of the stop rod 31 ensures that it can be quickly and firmly inserted into the opening 33 of the ring 32 after the electromagnet 35 is powered off, preventing the bidirectional screw rod 25 from rotating under the action of external forces such as wind loads and earthquakes during long-term use; at the same time, the alignment component 36 realizes the precise alignment of the building curtain wall through infrared signals, and its detection accuracy is high and is not affected by ambient light. When the building curtain wall is slightly offset, the infrared signal will be promptly fed back to the controller to ensure that the building curtain wall always maintains precise flatness and verticality, providing a strong guarantee for subsequent use and aesthetics.

[0038] A filling component 37 is also provided in the slot portion 27 , and the filling component 37 is used to fill the gap between the building curtain wall and the slot portion 27 to achieve sealing.

[0039] The filling assembly 37 includes an elastic filling strip 371 and a pressing unit;

[0040] The elastic filling strip 371 is made of rubber or silicone material. The shape of the elastic filling strip 371 matches the gap between the slot portion 27 and the building curtain wall, and is used to tightly fill the gap. The clamping unit is composed of a plurality of clamping plates 372 and an adjusting screw 373. The clamping plate 372 is located on the outside of the elastic filling strip 371. The adjusting screw 373 can push the clamping plate 372 to apply pressure to the elastic filling strip 371, so that the elastic filling strip 371 fills the gap.

[0041] The stop mechanism 3 further includes a linkage assembly 38 , which is used to transmit the power of the bidirectional screw 25 in the stop mechanism 3 to the adjusting screw 373 , and drive the adjusting screw 373 to push the pressing plate 372 .

[0042] The linkage assembly 38 comprises:

[0043] A transmission gear 381 is arranged on the bidirectional screw rod 25, and the transmission gear 381 is coaxially fixed with the bidirectional screw rod 25. A transmission rod 382 is arranged in the slot portion 27, and one end of the transmission rod 382 is provided with an outer gear ring 383 meshing with the transmission gear 381, and the other end of the transmission rod 382 is connected to the adjusting screw 373 in the filling component 37 through a bevel gear set 384, wherein the bevel gear set 384 includes a bevel gear fixed to the end of the transmission rod 382 and another bevel gear installed on the adjusting screw 373, and the two bevel gears are meshed with each other.

[0044] The bottom of the pressing piece 372 is slidably connected to a displacement groove provided on the bottom wall of the slot portion 27 , and the adjusting screw 373 is rotatably connected to the bracket, and the bracket is fixedly arranged on the bottom wall of the slot portion 27 .

[0045] In the present invention, the elastic filling strip 371 is customized according to the shape and size of the gap between the slot portion 27 and the building curtain wall. The material of the elastic filling strip 371, rubber or silicone, has good elasticity and plasticity and can fit the gap tightly. During the initial installation, the elastic filling strip 371 is in a natural state and may not completely fill the gap, but only plays a preliminary filling and buffering role. The clamping plate 372 of the clamping unit is located on one side of the elastic filling strip 371, and its bottom is slidably connected to the displacement groove of the bottom wall of the slot portion 27, ensuring stable movement in the horizontal direction. The adjusting screw 373 is rotatably connected to the bottom wall of the slot portion 27 through a bracket. When the adjusting screw 373 rotates, according to the principle of spiral transmission, the clamping plate 372 is pushed to move in a straight line along the displacement groove. When the adjusting screw 373 rotates, the rotational motion is converted into linear motion through the thread, so that the clamping plate 372 applies pressure to the elastic filling strip 371. As the pressing piece 372 is pushed forward, the elastic filling strip 371 is gradually compressed, and the elastic potential energy inside it increases, further filling and sealing the gap between the building curtain wall and the slot portion 27. At the same time, the contact surface of the pressing piece 372 and the elastic filling strip 371 can be specially processed, such as adding anti-slip texture or convex points, to increase friction and ensure a good sealing effect.

[0046] The filling component 37 achieves an excellent sealing effect through the combined action of the elastic filling strip 371 and the pressing unit. The elastic filling strip 371 can adapt to different gap shapes and sizes, and under the action of the pressing unit, it can fill complex irregular gaps and effectively prevent the penetration of rainwater, air, dust, etc.; and the improvement of the sealing performance directly brings about the energy-saving effect of the building. By reducing the exchange of indoor and outdoor air, it can effectively reduce the load of the building's HVAC system and reduce energy consumption, especially in cold or hot climate conditions, reducing the heat exchange caused by air infiltration and reducing the operating cost of the building;

[0047] Finally, since the building curtain wall can be accurately installed, reliably stopped and well sealed, the stability of the overall structure is significantly improved; the stopping mechanism 3 prevents the curtain wall from being displaced due to vibration and external force during long-term use, and the sealing of the filling component 37 reduces the erosion of the internal structure of the curtain wall by external factors, thereby extending the service life of the building curtain wall.

[0048] Through the above technical solution, on the one hand, during the installation of the building curtain wall, the rotation of the bidirectional screw 25 can not only complete the rapid installation of the curtain wall, but the power generated by it can also be transmitted to the filling component 37 through the linkage component 38, so as to realize the operation of the filling component 37 without the need for an additional power source; on the other hand, this linkage mechanism realizes the coordinated work of curtain wall installation, stopping, alignment and sealing, reduces the independent steps between different operations, and improves the overall installation and maintenance efficiency.

[0049] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
