Description

Technical Field

[0001] The utility model relates to the technical field of building decoration curtain walls, and particularly relates to a curtain wall system. Background Art

[0002] In order to endow building groups with a more unique cultural and historical heritage and a return to nature effect, many buildings now adopt red brick masonry and wet pasting of facing bricks in the exterior facade design. Ordinary red bricks, sintered brick masonry, and wet pasting of facing bricks are mostly used for the exterior facades of residential buildings and rarely used for public buildings. Moreover, the overall appearance is relatively unified into a large flat surface, which appears monotonous and single visually. The exterior facade composed of a real brick curtain wall + facing bricks + real brick masonry combination has a rich sense of hierarchy and individual rhythm changes, making the entire building "lively and active". Even if the same material is used in a large area, it will not be so rigid. Through the selection of materials and the optimization of the plan, the exterior facade of the building can achieve strong stability, safety, and an ideal appearance effect. Therefore, the exterior facades of some buildings with real brick finishes are suitable for real brick curtain wall construction. The real brick structure is usually connected and fixed to the keel, with high requirements for the positioning dimension accuracy of the keel. Coupled with the deviation of the main structure itself, the difficulty of pre-construction layout and positioning is large, and the workload is heavy. Even a slight deviation of the keel will affect the levelness of the real brick structure and may even result in rework, seriously affecting the construction progress. Content of the Utility Model

[0047] Referring to Figure 1 and Figure 2 , the present application proposes a curtain wall system, which is mainly installed on the outer side of the main building structure to play a role in aesthetics and protection. The curtain wall system includes: a brick component, a keel component, and a plurality of connectors 5. The keel component is connected to the main building structure. The brick component includes a plurality of brick bodies 6 connected to each other. Here, the brick body 6 can include building bricks such as ceramic bricks and porous sintered bricks in the prior art. The plurality of connectors 5 are horizontally arranged at preset intervals. The first end of each connector 5 is fixed between two adjacent brick bodies 6, and the second end of each connector 5 is connected to the keel component, thereby connecting the brick body 6 and the keel component, and the distance between the two ends of the connector 5 is adjustable.

[0048] In the existing curtain wall system, the positioning dimension accuracy requirements for the keel components are high. Coupled with the deviations existing in the main building structure itself, the difficulty of setting out and positioning in the early stage is great and the workload is large. If there is even a slight deviation in the keel components, the entire brick component will be tilted and unable to meet the flatness requirements. In this embodiment, the embedding accuracy requirements for the keel components are not particularly high. Even if there are deviations in the keel components, during the process of connecting the brick body 6 and the keel components, the construction personnel can adaptively adjust the distance between the two ends of the connecting piece 5 to adjust the distance between the brick body 6 and the keel components, so as to achieve the purpose of adjusting the flatness of the entire brick component, making the flatness meet the design requirements, thereby ensuring the stability and safety of the overall structure. At the same time, the workload and difficulty of setting out and positioning in the early stage are also reduced.

[0049] In a specific embodiment, referring to Figure 3 and Figure 4 , the connecting piece 5 includes a first connecting rod 51, a second connecting rod 52 and a fastening structure 53. The first connecting rod 51 is sleeved on the second connecting rod 52. The second connecting rod 52 can slide horizontally along the first connecting rod 51. The first connecting rod 51 is connected to the keel component, and the second connecting rod 52 is connected to the brick body. Both the first connecting rod 51 and the second connecting rod 52 are provided with positioning holes 54. When in use, when there are deviations in the keel components, by sliding the second connecting rod 52, the overall length of the connecting piece 5 is adaptively changed, that is, the distance between the two ends of the connecting piece 5 is adaptively adjusted, so as to achieve the purpose of adjusting the distance between the brick body 6 and the keel components, making the flatness meet the design requirements, thereby ensuring the stability and safety of the overall structure. Then, the fastening structure 53 passes through the positioning holes 54 to fasten the first connecting rod 51 and the second connecting rod 52, thereby fixing the position of the second connecting rod 52.

[0050] In a specific embodiment, referring to Figure 4 , the fastening structure 53 includes a bolt and a wing nut. The free end of the bolt passes through the positioning hole 54, and the wing nut is sleeved on the free end of the bolt and fastened to achieve the function of fixing the position of the second connecting rod 52.

[0051] In a specific embodiment, the connecting piece 5 includes round steel, and the round steel has the characteristics of good plasticity, good ductility and high strength. Good plasticity enables the round steel to better absorb energy when subjected to external forces and reduces the risk of fracture. High strength enables the round steel to bear a certain load and has a relatively high tensile strength and yield point. Therefore, as the connecting piece 5, the round steel can bear a certain load and maintain the structural stability of the curtain wall system. Due to the good ductility of the round steel, when the round steel is subjected to external forces, it can undergo plastic deformation without breaking, so that the construction personnel can adjust the bent length of the second end of the round steel and adjust the distance between the two ends of the round steel, so as to achieve the purpose of adjusting the distance between the brick body 6 and the keel components.

[0052] In a specific embodiment, referring to Figure 1 , the keel assembly includes a bolt 1, two embedded plates 2, and a vertically arranged L-shaped angle steel 3. The two embedded plates 2 are respectively connected to the upper and lower ends of the L-shaped angle steel 3, and the two embedded plates 2 are fixed to the building main structure through the bolt 1. Due to the L-shaped cross-section of the L-shaped angle steel 3, it has good bending strength and rigidity. As a keel, it can more effectively resist bending and torsion, ensuring the structural stability of the entire curtain wall system. The keels of traditional curtain walls are generally made of mortar masonry, which are relatively heavy, have a large load on the building main structure, high material costs, difficult vertical transportation, and low construction efficiency. Compared with traditional curtain walls, the curtain wall system of the present application adopts a steel structure keel design, which has a lighter weight and higher strength. Moreover, due to the high strength and stability of the L-shaped angle steel 3 itself, the amount of material used can be reduced, thereby reducing the project cost; due to the standardization of the shape and size of the L-shaped angle steel 3, the L-shaped angle steel 3 is easy to connect with other components during installation, improving the construction efficiency.

[0053] Referring to Figure 2 , for the relatively long brick body 6, multiple L-shaped angle steels 3 should be arranged at intervals to ensure the stability of the overall structure, and multiple connectors 5 should be arranged at intervals and connected to the corresponding L-shaped angle steels 3. In this embodiment, the number and spacing of the L-shaped angle steels 3 and the connectors 5 are determined according to the size of the brick body 6. The specific specifications of the L-shaped angle steels 3 and the connectors 5 should not be used to limit the present application.

[0054] In a specific embodiment, the keel assembly further includes a flexible gasket (not shown in the figure). The flexible gasket is arranged between the bolt 1 and the embedded plate 2 to buffer the friction force between different steel structure members and increase the service life.

[0055] In a specific embodiment, referring to Figure 1 , the keel assembly further includes a fireproof rock wool structure 9. The fireproof rock wool structure 9 is fixed between the embedded plate 2 and the brick body 6. The fireproof rock wool structure 9 can play a fireproof role and increase safety.

[0056] In a specific embodiment, the keel assembly further includes a plurality of connecting cables (shown in the figure). At least two connecting cables are symmetrically arranged at the upper and lower ends of the L-shaped angle steel 3 respectively, and the two ends of the connecting cable are respectively connected to the L-shaped angle steel 3 and the embedded plate 2. By arranging the connecting cables, on the one hand, the connection reliability between the L-shaped angle steel 3 and the embedded plate 2 can be strengthened; on the other hand, since the connecting cables are symmetrically arranged on the left and right sides of the L-shaped angle steel 3, the centering of the L-shaped angle steel 3 can be ensured, avoiding the problem of the L-shaped angle steel 3 tilting.

[0057] In a specific embodiment, referring to Figure 1, the brick body 6 is provided with reserved holes (not shown in the figure), and the vertical steel bars 4 vertically pass through the reserved holes of the upper and lower corresponding brick bodies 6 to fix each brick body 6. Refer to Figure 2 , for the relatively long brick body 6, a plurality of vertical steel bars should be arranged at intervals to ensure the stability of the overall structure. Here, the number and spacing of the vertical steel bars 4 are determined according to the size of the brick body 6. The specific size, specifications, etc. of the vertical steel bars 4 should not be regarded as a limitation to this application. The cross-section of the vertical steel bar 4 can be circular, and the reserved hole is also designed as a corresponding circular through-hole. The design of the circular through-hole makes the opening of the brick body 6 smaller, improves the overall strength of the brick body 6, and the processing of the circular through-hole is also simpler.

[0058] Compared with the traditional curtain wall made of mortar, the curtain wall system in this embodiment uses vertical steel bars 4 to string and fix each brick body 6, and utilizes the strength and durability of the vertical steel bars 4 to fix the brick body 6, which has the advantages of high strength and good durability, is conducive to reducing self-weight and cost. Moreover, the structure is simple, materials are saved, the construction efficiency is high, the operation and maintenance are convenient, the reliability of the curtain wall system is improved, the construction quality is guaranteed, and potential safety hazards are reduced.

[0059] In a specific embodiment, refer to Figure 1 , the brick assembly includes a plurality of filling layers 7, and a filling layer 7 is provided between two adjacent upper and lower brick bodies 6. Here, the filling layer 7 can adopt mortar in the prior art, which can play a role in bonding adjacent brick bodies 6. At the same time, the mortar can fill the brick joints between the brick bodies 6, improve the overall density and integrity of the brick bodies 6, and help enhance the strength and stability of the brick bodies 6. The first end of the connecting piece 5 is fixed to the corresponding filling layer 7, and the connecting piece 5 is fixed through the filling layer 7 and bonded to the brick body 6 as a whole, ensuring the tight connection between the connecting piece 5 and the brick body 6, preventing the relative sliding or separation of the two, and thus improving the overall stability.

[0060] In a conventional curtain wall system, the brick body 6 is directly welded to the keel, without considering the mortar settlement deformation between the brick bodies 6 and the obvious cracks generated by the overall settlement deformation of the brick bodies 6 in the later stage. Compared with the conventional curtain wall system, in this embodiment, round steel is used to connect the brick body 6 with the keel assembly. The diameter of the round steel is smaller than the spacing between two adjacent brick bodies 6, so that the round steel can be completely wrapped in the filling layer 7. Even if the brick body 6 settles and the brick body 6 settles as a whole, the flexibility and ductility of the round steel can be adjusted within a certain range, effectively alleviating the situation of settlement deformation and no obvious gaps will appear.

[0061] In a specific embodiment, refer to Figure 1, the brick body assembly further includes a plurality of sealing layers 8. A sealing layer 8 is provided on the side of the filling layer 7 away from the connecting member 5. The sealing layer 8 is used to absorb the expansion and contraction deformation between the brick body 6 and the filling layer 7. Here, the sealing layer 8 can adopt a caulking agent in the prior art. The caulking agent can play a role in absorbing the expansion and contraction deformation, reducing the deformation or cracking of the filling layer 7 caused by factors such as temperature change and humidity change, and improving the stability of the overall structure of the brick body 6. At the same time, the caulking agent has good waterproofness and mildew resistance, and can effectively prevent water molecules from penetrating into the brick joints between the brick bodies 6, protecting the brick bodies 6 from getting damp and deteriorating.

[0062] A curtain wall system described in the present utility model is a curtain wall system that can be constructed only after the completion of the building main structure. The installation process of the curtain wall system can include:

[0063] According to the structural force analysis and calculation, determine the specifications of the L-shaped angle steel. According to the arrangement of the L-shaped angle steel, measure and set out the lines, and fix the embedded plate to the building main structure with bolts at the corresponding positions. During the installation of the embedded plate, it should be noted that the two embedded plates are installed in the same vertical projection area;

[0064] After the construction of the embedded plate is completed, place the L-shaped angle steel between the two embedded plates, and ensure that the connecting cable is symmetric about the L-shaped angle steel to ensure the centering of the L-shaped angle steel. Weld the connecting cable, L-shaped angle steel and the embedded plate. After the welding is completed, remove the welding slag from the weld and perform anti-corrosion treatment;

[0065] Fix the fireproof rock wool structure at the preset position of the embedded plate corresponding to the brick body;

[0066] The brick body is constructed by single-piece brick bodies upward. The brick body is provided with a reserved hole that penetrates up and down. The vertical steel bars pass through the reserved holes of the brick bodies corresponding up and down, and insert the first end of the connecting member between the corresponding brick bodies. Mortar is used to build each brick body. When building, high-standard cement mortar is used to reduce the phenomenon of alkali return as much as possible;

[0067] After the brick body is completed in masonry, it needs to be caulked with a caulking agent to form a sealing layer. During the caulking process, press the gap as much as possible to achieve the effect of a concave joint, highlighting the overall effect of the brick body;

[0068] Connect the second end of the connecting member to the L-shaped angle steel. During this process, use a laser plumb instrument or a plumb bob to measure and calibrate the overall verticality of the brick body assembly, and adaptively adjust the distance between the two ends of the connecting member to ensure the overall verticality of the brick body assembly.

The present disclosure is not limited to the exact structures described above and shown in the drawings, and various modifications and changes can be made without departing from its scope.
