Description

Technical Field

[0001] The utility model relates to the technical field of building structures, in particular to a dry-hanging split facing brick building curtain wall construction system. Background Art

[0002] With the improvement of living standards in modern society, people's requirements for the comfort and aesthetics of their environment have been significantly improved. With the development of the times, architectural styles have gradually diversified, volume shapes have continued to increase, and the requirements for urban planning and design, construction technology and material application have gradually increased.

[0003] The same is true for exterior wall finishing. As building forms continue to evolve and heights gradually increase, the requirements for the performance of exterior wall decoration materials and construction techniques are becoming increasingly stringent. Traditional wet-pasting processes are prone to alkali efflorescence, poor adhesion, seismic resistance, displacement resistance, and temperature deformation resistance, and the tendency of the colloid and bricks to fall off. These defects make them unsuitable for large-scale, complex, or high-rise buildings, and they no longer meet the requirements of modern construction. Therefore, seeking alternative solutions has become a necessity for modern architecture.

[0004] Benefiting from technological advancements and stemming from the concept of free-standing facades in modern architectural theory, curtain wall and dry-hanging techniques were born. Architects utilize large, continuous expanses of material to cover the entire building surface, freeing themselves from the constraints of traditional facade design and imbuing the building with unprecedented visual impact. Modern curtain wall dry-hanging technology utilizes lighter, more durable materials and more advanced processes, improving installation efficiency and service life, making it a common technique in modern architectural decoration. It is widely used in commercial buildings (such as hotels, shopping malls, and office buildings), public buildings (such as museums, libraries, and theaters), and some high-quality residential buildings.

[0005] Therefore, it is necessary to rely on technology to better design the curtain wall structure of brick buildings to better meet social needs. Utility Model Content

[0006] The purpose of the utility model is to overcome the shortcomings and defects of the existing technology and provide a dry-hanging split facing brick building curtain wall construction system, which can be widely used in high-rise buildings and various types of multi-story civil buildings with complex shapes. The whole adopts flexible connection and has good earthquake resistance, displacement resistance and temperature deformation resistance.

[0007] A dry-hanging split facing brick building curtain wall construction system is composed of the following layers from the inside to the outside: a reinforced concrete building load-bearing structure, an exterior wall insulation layer, an exterior wall waterproof layer, an air space, steel pipe columns, transverse angle steel keels, decorative panel hangers, and exterior wall facing bricks; the exterior wall facing bricks are supported and suspended by the decorative panel hangers, the decorative panel hangers are mounted on the transverse angle steel keels, and the transverse angle steel keels are fixed to the steel pipe columns.

[0008] The steel pipe columns are bolted to the outwardly extending fixed angle steels, and the outwardly extending fixed angle steels are welded to the pre-embedded steel plates in the wall.

[0009] The transverse angle steel keels are arranged at equal intervals according to the building height.

[0010] Wherein, the transverse angle steel keel is welded and fixed to the steel pipe column.

[0011] Wherein, the decorative panel hanger is installed on the transverse angle steel keel bolt connection.

[0012] The steel pipe columns are rectangular tubular structures in cross section, and are multiple and spaced apart.

[0013] The top and bottom of the back of the exterior wall facing brick are provided with grooves or protrusions that match the decorative panel hanger.

[0014] Among them, the decorative panel hanger is an "I"-shaped hanger.

[0015] Wherein, a fireproof isolation belt is laid on the outside of the exterior wall waterproof layer.

[0016] The utility model provides a split facing brick building curtain wall construction system that can be installed by dry hanging technology. On the premise of meeting the functional requirements, it breaks the traditional wet process and innovatively connects the facing bricks with the horizontal keel and the column by using back hanging parts to achieve reliable hanging with the building main body. The bricks themselves are small in size and light in weight, and are reliably hung and not easy to fall off. It takes into account both safety and longevity and is widely applicable to high-rise buildings and various types of multi-story civil buildings with complex shapes. The whole system adopts flexible connection and has good earthquake resistance, displacement resistance and temperature deformation resistance.

[0017] In the present invention, the horizontal and vertical brick joints of the facing bricks are hung to naturally form a concave and convex facade effect, eliminating the filling and grouting procedures after the wet process facing bricks are laid, avoiding the grouting falling off caused by colloid aging, and the brick joints are open to form natural ventilation corridors with the internal air layer, realizing external air circulation, which is beneficial to reducing building energy consumption and improving indoor comfort.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] Explanation of terms:

[0024] Dry hanging: It is a construction technology of modern building decoration engineering, mainly used for wall decoration of stone or other materials. This technology involves the use of metal hangers to hang the decorative panels directly on the main structure instead of through traditional pouring and pasting methods.

[0025] Wet-installation: refers to an installation method in which the stone is directly attached to the structure using cement or tree-based adhesives to form a finish.

[0026] Curtain wall: It is the outer wall of a building, does not bear weight, and is hung like a curtain, so it is called "curtain wall". It is a lightweight wall with decorative effect commonly used in modern large and high-rise buildings. It is composed of panels and a supporting structure system. It has a certain displacement or deformation capacity relative to the main structure. It does not bear the role of the main structure. It is a building's external protective structure or decorative structure.

[0027] Split brick, also known as split brick or split-off brick, is a type of facing brick, widely favored for its unique texture and delicate feel. It's made from clay, granulated, and then cut to create a surface with surface grain and shallow grooves. It's primarily laid with adhesive backing, followed by grouting and caulking.

[0028] At present, regarding building curtain walls, there are existing national standards "Technical Specifications for Metal and Stone Curtain Wall Engineering" JGJ133-2001, "Technical Specifications for Artificial Board Curtain Wall Engineering" JGJ336-2016 and the national building standard design atlas "Building Curtain Wall" 13J103 (1-7) for reference.

[0029] The utility model improves and optimizes the conventional design of artificial board curtain wall structure through systematic research on existing national standards and atlases, and proposes a method combining it with split facing brick materials (generally laid using a wet process).

[0030] See also Figure 1 、 Figure 2 、 Figure 3 as well as Figure 4As shown, the dry-hanging split facing brick building curtain wall structure system provided by the present invention is composed of the following layers from the inside to the outside: a reinforced concrete building load-bearing structure 10, an exterior wall insulation layer 11, an exterior wall waterproof layer 12, an air layer 13, steel pipe columns 14, transverse angle steel keels 15, decorative panel hangers 16, and exterior wall facing bricks 17. The bottom of the reinforced concrete building load-bearing structure 10 is a wall enclosure structure 30.

[0031] In some embodiments, the steel pipe column 14 is bolted to the extended fixed angle steel 20, and the extended fixed angle steel is welded to the wall embedded steel plate 21. In some embodiments, the transverse angle steel keels 15 are arranged at equal intervals according to the building height. In some embodiments, the transverse angle steel keels 15 are welded and fixed to the steel pipe column 14. In some embodiments, the decorative panel hanger 16 is installed on the transverse angle steel keel 15 and bolted. In some embodiments, the steel pipe column 14 is a rectangular tubular structure with a plurality of cross-sections and is arranged at intervals.

[0032] In some embodiments, the top and bottom of the back of the exterior wall facing brick 17 have grooves or protrusions that cooperate with the decorative panel hanger 16. In some embodiments, the decorative panel hanger 16 is an "I"-shaped hanger. The connection method of the exterior wall facing brick 17 and the decorative panel hanger 16 is as follows: Figure 4 shown.

[0033] In some embodiments, a fireproof isolation belt 40 is laid on the outside of the exterior wall waterproof layer. The fireproof isolation belt 40 is wrapped around the outside of the exterior wall waterproof layer and the inside of the exterior wall facing bricks 17 to play a role of fireproof isolation.

[0034] The brief construction process of the dry-hanging split facing brick building curtain wall system of the utility model is as follows:

[0035] (1) First complete the main structure construction, and pre-embed the embedded steel plates during construction.

[0036] (2) According to the spacing arrangement of steel pipe columns, the outward-extending fixed angle steel is constructed. The outward-extending fixed angle steel is extended to the designed position, and the thickness of the wall is reserved. The inner side of the angle steel is welded to the embedded steel plate of the wall.

[0037] (3) During the construction of the exterior wall insulation layer, it will automatically disconnect when encountering a fixed angle steel position.

[0038] (4) Carry out the construction of the exterior wall waterproof layer, and after the waterproof construction is completed, lay the fire isolation belt.

[0039] (5) Construct steel pipe columns according to the layout spacing, and bolt the steel pipe columns to the fixed angle steels.

[0040] (6) According to the requirements of plate installation, transverse angle steel keels are set at equal intervals along the height of the building, and the transverse angle steel keels are connected to the columns by welding.

[0041] (7) Construction of special hangers: After the special hangers are bolted to the horizontal angle steel keel, the facing tiles are hung externally in layers.

[0042] Compared with conventional dry-hanging split facing brick building curtain wall construction system, the utility model has the following unique advantages:

[0043] (1) This utility model innovatively applies the dry hanging process to the installation of split facing tiles, breaking the constraints of the wet method and achieving reliable hanging of bricks. It is widely used in various types of multi-story civil buildings and high-rise buildings with complex shapes.

[0044] This new design combines the installation of split facing tiles with dry-hanging techniques. By providing a full-length groove on the back of the tiles, these tiles are bolted to the building's outrigger columns and welded to transverse angle steel keels. The tiles are mounted individually. The unfolded area of a single tile is only 1 / 5 to 1 / 8 of that of a conventional man-made panel curtain wall, and its weight is only 1 / 8 to 1 / 15. This makes it suitable for various multi-story residential buildings with complex structures and dramatically changing facades, as well as high-rise buildings subject to high wind loads.

[0045] (2) The entire system of the utility model can be regarded as a flexible structure outside the rigid body of the building. It can adapt to the material's own expansion and deformation caused by climate and temperature changes, loads, and structural displacement under the influence of earthquakes. It can meet the design requirements of different environmental categories, climate zones, and seismic fortifications, and has good comprehensive performance.

[0046] This new system is welded to the building's main structure via pre-embedded steel plates embedded within the load-bearing structure. Extended fixed angle steel is then bolted to the square steel tube columns. Transverse angle steel keels are welded between the columns at equal intervals, consistent with tile installation requirements. The tile hangers are then bolted to the transverse angle steel keels. A rigid connection between the columns and the transverse keels ensures the strength of the framework. Bolting at other locations allows for structural deformation and displacement. This secure connection ensures overall structural strength and excellent resistance to earthquakes, displacement, and temperature deformation.

[0047] (3) The tiles are hung to create a contrasting convex-concave facade effect, eliminating the need for subsequent filling or grouting. This improves the aesthetics while effectively preventing the aging and shedding of the colloid in the tiles. The tiles are independent units that can be installed or removed individually, making them easy to maintain and replace.

[0048] The utility model is a system of facing bricks with back-hanging grooves on the top and sides, which can form a "real seam" effect with sharp contrast in horizontal and vertical lengths after hanging. The depth and width of the brick seam grooves can be determined according to design requirements, generally up to 3 to 5 mm.

[0049] Compared to traditional wet-processing, this method eliminates the need for grouting or filling gaps between tiles, effectively preventing joint loss caused by colloid aging. Furthermore, tile units can be independently disassembled and replaced, facilitating maintenance and replacement without the need to dismantle surrounding tiles or joints.

[0050] (4) The utility model system cleverly uses the joints between facing bricks as air inlets and outlets, and the air layer reserved between the interior of the curtain wall and the building insulation layer is used as a corridor to realize external air circulation and achieve ideal ventilation effect, which is conducive to reducing building energy consumption and increasing indoor comfort.

[0051] The facing bricks of the utility model system are hung, and the joints between the bricks are open. A fully covered insulation layer is provided on the outside of the building main body, which can be regarded as a closed structure to block heat transfer. An air layer (air cavity) is provided between the insulation layer and the curtain wall. The system uses the brick joints as air inlets (outlets) to realize local external circulation with the air in the air layer. In summer, the sunlight radiation causes the air outside the curtain wall to heat up greatly, while the temperature of the gas in the air layer of the curtain wall rises relatively little. The temperature difference forms a directional circulation flow of air on both sides of the curtain wall, and the opposite is true in winter, thereby achieving an ideal ventilation effect, which is beneficial to reducing building energy consumption and increasing indoor comfort.

[0052] (5) The architectural structure, construction materials and processes of the utility model system are all mature products that have been factory-produced in batches and can be directly constructed and installed on site. They are characterized by convenient procurement, low cost, short construction period, high construction efficiency and small environmental impact, and are in line with the future development direction of green construction (building materials) technology.

[0053] (6) The utility model system is based on the concept of sustainable development, fully responds to the development requirements of green buildings, and combines the guiding ideology of my country's urban development planning and sponge-type buildings. The solution provided fully retains the advantages of traditional architectural design and construction technology, while incorporating technological innovation results. The solution is in line with the future development direction of green construction technology and has great application prospects.

[0054] (7) The system of the utility model can be flexibly adjusted to increase or decrease the level structure according to different environmental categories, building functions and styles, structural types, etc. The accessories and building materials used can be arbitrarily adjusted according to different building categories, building fire resistance levels and earthquake resistance requirements; it can meet various design requirements, has strong practicality, and has certain social promotion and economic value.

It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.
