Description

Technical Field

[0001] This invention belongs to the field of building curtain wall technology, specifically relating to a prefabricated hanging structure and construction process for ceramic brick curtain walls. Background Technology

[0002] In recent years, the richness and aesthetics of building facade decoration have increasingly attracted the attention of designers and the public. Among the many forms of facade decoration, curtain walls are widely used due to their strong adaptability and diverse forms. Currently, common curtain wall types include glass curtain walls, aluminum composite panel curtain walls, and stone curtain walls. Among them, stone curtain walls, with terracotta bricks as the facing material, have gained high market recognition and become an important component of the stone curtain wall system due to their characteristics such as long-lasting color, regular surface, natural simplicity, and environmental friendliness.

[0003] The conventional construction method for terracotta bricks involves reinforcing them with steel bars and securing them with cement grout. However, in scenarios using long strips of terracotta bricks or with complex masonry modules, the overlapping of the bricks often becomes complicated, and the requirements for installation precision increase accordingly. If traditional masonry methods are continued, it becomes difficult to accurately control the flatness of the bricks and the overlapping structure during construction. Coupled with factors such as varying skill levels among masons and the gradual accumulation of errors during construction, the overall construction quality of the curtain wall is ultimately difficult to guarantee.

[0004] Furthermore, if terracotta bricks become damaged during subsequent use, traditional repair methods require first removing the cement grout and then dismantling the damaged brick. Replacing the brick with a new one often damages surrounding intact bricks, which not only increases the difficulty of repairs but also significantly raises maintenance costs. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides the following technical solution: A prefabricated hanging structure for terracotta brick curtain walls includes: a square tube frame comprising multiple vertical square tubes perpendicular to the ground; multiple metal hangers, parallel to the ground, evenly spaced along the height of the vertical square tubes and fixed to the vertical square tubes by bolts or welding; each metal hanger includes a front baffle, a rear baffle, and a connecting piece located between the front baffle and the rear baffle; the rear baffle is positioned close to the vertical square tube, the front baffle and the rear baffle are parallel and spaced apart, the width of the front baffle is smaller than the width of the rear baffle, and the two ends of the connecting piece are respectively connected to the front baffle and the rear baffle; the front baffle and the connecting piece... The lower part, together with the rear baffle, forms a first receiving space; the terracotta brick has a first locking block and a second locking block on its side wall facing the metal hanger, arranged vertically from top to bottom, with the top and bottom of the first and second locking blocks forming a locking gap with the side wall of the terracotta brick; an installation unit of the terracotta brick is formed between two adjacent metal hangers, and the connecting piece of the metal hanger located below the terracotta brick is used to support the second locking block, with the locking gap at the bottom of the second locking block engaging with the front baffle; the first receiving space of the metal hanger located above the terracotta brick is used to receive the first locking block.

[0006] In some embodiments, the bottom of the vertical square tube is fixedly connected to the ground using pre-embedded anchors, chemical anchors, or rebar anchoring.

[0007] In some embodiments, the metal pendant is made of aluminum.

[0008] In some embodiments, the rear baffle is fixedly connected to the vertical square tube by bolts or welding.

[0009] This invention also provides a construction process based on the above-mentioned prefabricated hanging structure of terracotta brick curtain wall, including the following steps: fixing the bottom of the vertical square tube to the ground; according to the construction drawings and the dimensions of the terracotta brick, sequentially fixing and installing multiple metal hangers on the vertical square tube; forming an installation unit for the terracotta brick between two adjacent sets of metal hangers; pushing the terracotta brick into the side of the adjacent metal hanger, so that the connecting piece of the metal hanger below the terracotta brick supports the second clip, and making the snap-fit ​​gap at the bottom of the second clip engage with the front baffle of the metal hanger below; simultaneously, making the first receiving space of the metal hanger above the terracotta brick accommodate the first clip, completing the hanging of a single terracotta brick; sequentially installing the terracotta bricks of the entire curtain wall piece by piece and row by row; In some implementations, the gaps between adjacent terracotta bricks are cleaned and sealed with weather-resistant sealant.

[0010] In some embodiments, the bottom of the vertical square tube is fixed to the ground by one of the following methods: pre-embedded anchor bolts, chemical anchor bolts, or rebar anchoring.

[0011] In some embodiments, when the vertical square tube is fixed to the ground, a straightedge and a theodolite are used to correct the verticality of the vertical square tube and the spacing between the members in real time to ensure that the verticality deviation of the vertical square tube is ≤3mm / m, the flatness deviation is ≤2mm / m, and the spacing deviation is ≤10mm.

[0012] In some embodiments, the installation spacing between adjacent metal hangers is controlled to be within 50 mm.

[0013] In some embodiments, the terracotta bricks, after installation, meet the following quality standards: surface flatness deviation ≤ 2mm, verticality deviation ≤ 3mm, joint width deviation ≤ 1mm, and height difference between adjacent bricks ≤ 1mm.

[0014] Compared with the prior art, the prefabricated hanging structure and construction process of ceramic brick curtain walls provided by the present invention have the following beneficial effects: 1. The prefabricated hanging structure for terracotta brick curtain walls provided by this invention uses metal hangers to suspend terracotta bricks, eliminating the need for mortar bonding and fundamentally preventing problems such as detachment, cracking, water seepage, and aging that are prone to occur in traditional terracotta brick curtain walls. 2. The metal hanger provided by this invention provides bidirectional positioning of the terracotta brick: the upper surface of the connecting piece of the metal hanger below the terracotta brick supports the second locking block, while the higher part of the front baffle engages with the locking gap at the bottom of the second locking block, achieving support (vertical positioning); the hanger above the terracotta brick uses the first receiving space formed by the front baffle, connecting piece, and rear baffle to accommodate the first locking block, achieving lateral positioning of the terracotta brick. The upper and lower metal hangers work together to prevent the terracotta brick from sinking and tilting outwards. 3. The metal hanger provided by this invention can significantly improve the installation efficiency of terracotta bricks and speed up the construction progress; the terracotta bricks adopt a horizontal side-push-in hanging method, which eliminates the need for wet operation and curing, makes single-piece installation convenient, and allows for continuous flow operation, effectively shortening the overall construction period. 4. Since each terracotta brick is installed independently and is snap-fitted to the metal bracket, individual bricks can be pulled out or replaced directly from the side later without large-scale dismantling, which greatly reduces the difficulty of inspection and maintenance and the cost of maintenance.

[0020] Furthermore, in the description of this invention, the terms "first," "second," etc., are used only for distinguishing descriptions and should not be construed as indicating or implying relative importance.

[0021] The terracotta brick curtain wall prefabricated hanging structure provided by this invention includes a square tube frame 1, metal hangers 2, and terracotta bricks 3, with the following specific structural features: The aforementioned square tube frame 1 mainly serves to fix the metal hangers 2 and the terracotta bricks 3. The square tube frame 1 includes multiple vertical square tubes 11 set perpendicular to the ground 4. The bottom of the vertical square tubes 11 is firmly fixed to the ground 4. Pre-embedded anchor bolts or concrete base reinforcement can be used for connection, and the appropriate method can be flexibly selected according to the site geological conditions and load level.

[0022] The aforementioned metal bracket 2 is a special connecting component between the terracotta brick 3 and the square tube frame 1. The metal bracket 2 is preferably made of aluminum alloy, which has the advantages of being lightweight, high-strength, corrosion-resistant, and not easily oxidized and deformed, and can be adapted to the long-term use environment of outdoor curtain walls.

[0023] In the vertical arrangement, a metal hanger 2 parallel to the ground 4 is provided between two adjacent vertical square tubes 11. The metal hanger 2 is evenly arranged at a certain interval along the height direction of the vertical square tubes 11 and is fixedly connected to the vertical square tubes 11 by bolts or welding.

[0024] The metal bracket 2 includes a front baffle 21, a rear baffle 22, and a connecting piece 23. The rear baffle 22 is arranged close to the side of the vertical square tube 11 for connection with it. The front baffle 21 and the rear baffle 22 are parallel to each other and maintain a certain distance, with the width of the front baffle 21 being smaller than the width of the rear baffle 22. The connecting piece 23 is located between the front baffle 21 and the rear baffle 22, and its two ends are connected to the front baffle 21 and the rear baffle 22, respectively. The front baffle 21, the connecting piece 23, and the rear baffle 22 together form a first accommodating space 24.

[0025] The aforementioned terracotta brick 3 is a decorative component of the exterior facade of the curtain wall. On the side wall of the terracotta brick 3 facing the metal hanger 2, a first locking block 31 and a second locking block 32 are provided vertically from top to bottom. The top and bottom of the first locking block 31 and the second locking block 32 respectively form a locking gap 33 with the side wall of the terracotta brick 3, which is used to engage and position with the front baffle 21 of the metal hanger 2.

[0026] The adjacent metal hangers 2 are detachably connected to the terracotta bricks 3. The specific assembly method is as follows: The metal hanger 2 located below the terracotta brick 3 has its connecting piece 23 upper surface used to support the second locking block 32. The bottom of the second locking block 32 is placed stably on the connecting piece 23. At the same time, the locking gap 33 between the bottom of the second locking block 32 and the side wall of the terracotta brick 3 is precisely locked into the part of the front baffle 21 that is higher than the connecting piece 23. The metal hanger 2 located below the terracotta brick 3 mainly serves to support the terracotta brick 3. The metal hanger 2 located above the terracotta brick 3, with its front baffle 21, the bottom of the connecting piece 23, and the rear baffle 22 together forming a first receiving space 24, is used to receive the first locking block 31, thereby achieving lateral positioning of the terracotta brick 3.

[0027] Similarly, two adjacent sets of metal hangers 2 form an independent installation unit, and the space of the installation unit can just accommodate a terracotta brick 3. During installation, the terracotta brick 3 is pushed horizontally from the side (left or right) of the adjacent metal hanger 2 until the first locking block 31 is fully inserted into the first accommodating space 24 and the bottom of the second locking block 32 is fully supported by the connecting piece 23 below, thus completing the quick installation of a single terracotta brick 3.

[0028] Metal hanger 2 serves as the main support and positioning component for terracotta brick 3, used to snap and fix terracotta brick 3, realizing the suspended hanging of terracotta brick 3, fundamentally avoiding problems such as falling off, cracking, water seepage, and aging that are prone to occur in traditional adhesive processes; moreover, this hanging structure allows each terracotta brick 3 to bear force independently without interfering with each other, with high installation accuracy and good stability, and individual bricks can be directly disassembled, inspected, or replaced in the later stage without large-scale dismantling, making maintenance convenient.

[0029] Furthermore, the connection between the metal hanger 2 and the vertical square tube 11 is achieved by the rear baffle 22 of the metal hanger 2 fitting and positioning with the vertical square tube 11, and then rigidly fixing it by bolt fastening or welding.

[0030] Install vertical square tubes 11 sequentially according to the marked lines. The bottom of the vertical square tubes 11 is firmly fixed to the ground foundation 4. This can be done by using pre-embedded anchors, chemical anchors, or rebar fixing.

[0031] During the installation process, straightedges and theodolites were used for real-time calibration to strictly control the verticality of the vertical square tubes 11 and the spacing between the members, ensuring that the vertical components are evenly and parallelly arranged, and that the overall square tube frame 1 is subjected to balanced forces and has strong stability.

[0032] After the vertical square tube 11 is installed and passes inspection, the surface of the pipe fittings and connection nodes are subjected to comprehensive anti-corrosion treatment, and anti-rust paint is evenly applied to effectively improve the corrosion resistance and service life of the pipe fittings.

[0033] S2. Install metal brackets Based on the construction drawings and the dimensions of the terracotta brick 3, mark the installation points of the metal hangers 2 on the surface of the vertical square tube 11 to ensure accurate positioning and uniform spacing.

[0034] The rear baffle 22 of the metal hanger 2 is attached to the vertical square tube 11 and fastened with high-strength bolts to ensure a tight fit and a firm connection.

[0035] According to the designed vertical spacing, all metal hangers 2 are fixed from top to bottom. After installation, each connection node is checked one by one to ensure that the bolts are tight and the connection is reliable. The metal hangers 2 are evenly arranged, with consistent spacing and stable stress, providing a reliable support benchmark for the subsequent installation of terracotta bricks 3.

[0036] S3, Install terracotta bricks Two adjacent sets of metal hangers 2 form an independent installation unit. The unit space size matches the single terracotta brick 3, and can just accommodate one terracotta brick 3.

[0037] During installation, the terracotta brick 3 is pushed horizontally into the side (left or right) of the adjacent metal hanger 2, so that the upper surface of the connecting piece 23 of the lower metal hanger 2 smoothly supports the second locking block 32 of the terracotta brick 3. The locking gap 33 formed by the bottom of the second locking block 32 and the side wall of the terracotta brick 3 precisely engages with the front baffle 21 of the metal hanger 2. The first receiving space 24 formed by the front baffle 21, the lower part of the connecting piece 23 and the rear baffle 22 of the upper metal hanger 2 accommodates the first locking block 31 of the upper part of the terracotta brick 3, thereby completing the quick installation of a single terracotta brick 3.

[0038] After each individual brick is installed, the installation of the entire curtain wall terracotta brick 3 is completed piece by piece and row by row in the same manner as described above, ensuring that the exterior facade is flat and straight and the brick joints are uniform.

[0039] S4. Sealing treatment of gaps in terracotta bricks After the terracotta bricks 3 are installed and pass inspection, the gaps between adjacent terracotta bricks 3 are thoroughly cleaned to remove dust, debris, residual mortar, and other contaminants. Then, a weather-resistant sealant matching the color of the terracotta bricks 3 is applied. During the application process, it is ensured that the sealant layer is full, continuous, and without breaks, resulting in a smooth and even surface. Problems such as bubbles, drips, cracks, and insufficient sealant are avoided, balancing the curtain wall's sealing and waterproofing performance with its aesthetic appeal.

[0040] To ensure the overall construction quality of the curtain wall, each construction process from S1 to S4 and the formed components must strictly adhere to the following quality standards: Vertical square tube 11: verticality deviation ≤3mm / m, flatness deviation ≤2mm / m, spacing deviation ≤10mm; aluminum metal hanger 2: position deviation ≤5mm and bolts tight and not loose; terracotta brick 3: surface flatness deviation ≤2mm, verticality deviation ≤3mm, joint width deviation ≤1mm, height difference between adjacent bricks ≤1mm; sealant joints should be full, flat and smooth, and the width and depth should conform to the design.

[0041] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
