Description

Technical Field

[0001] This utility model relates to the field of building wall construction technology, specifically to a porous brick wall dry-hanging brick structure that does not require main keel support. Background Technology

[0002] Traditional methods for installing dry-hanging wall tiles on porous brick walls typically require a complex support system consisting of main and secondary joists. The main joists are usually directly fixed to the wall using expansion bolts or chemical anchors, the secondary joists are then connected to the main joists, and finally, dry-hanging components are installed on the secondary joists to secure the wall tiles. This structure has the following drawbacks: First, porous brick walls have relatively low strength, requiring numerous anchor points during main joist installation, which can easily lead to brick cracking or insecure anchoring. Second, the main joist system is complex to construct, requiring on-site measurement, cutting, and assembly, resulting in low efficiency. Third, the main joists occupy a large amount of space, reducing usable floor area. Fourth, material costs are high, especially in large-scale projects where a large quantity of main joists is used. Furthermore, the porous structure of porous brick walls makes the installation of embedded parts difficult, directly affecting the stability and safety of the dry-hanging system. Therefore, a dry-hanging wall tile structure that simplifies the structure, improves construction efficiency, reduces costs, and ensures stability is needed. Utility Model Content

[0003] The purpose of this invention is to provide a porous brick wall structure that does not require main keel support for dry-hanging brickwork, in order to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides a porous brick wall structure that does not require main keel support and is dry-hanging. The structure includes a porous brick wall, on which horizontally and vertically spaced concrete embedded blocks are provided. U-shaped screws are embedded in the concrete embedded blocks, and horizontal angle steel secondary keels are connected to the U-shaped screws. The ends of the horizontal angle steel secondary keels are connected through vertical angle steel secondary keels, and L-shaped dry-hanging fasteners are connected to the horizontal angle steel secondary keels.

[0005] According to one embodiment of the present invention, the horizontal center-to-center distance between the horizontally spaced concrete embedded blocks is no greater than 650mm.

[0006] According to one embodiment of the present invention, the edge of the vertically spaced concrete embedded block is not less than 150mm from the upper and lower edges of the ceramic tile.

[0007] According to one embodiment of this utility model, the horizontal and vertical angle steel secondary keels are made of galvanized angle steel with a specification of 50mm×50mm×4mm.

[0008] According to one embodiment of the present invention, the U-shaped screw is made of galvanized carbon steel, the screw thread length is 80mm, the thread diameter is 8mm, the inner diameter of the two screws is 114mm, and the length of the screw exposed on the side of the concrete embedded block is not less than 50mm.

[0009] According to one embodiment of the present invention, the concrete embedded block is cast using commercial concrete with a strength of not less than C25.

[0010] According to one embodiment of this utility model, the length of the horizontal angle steel secondary keel is no more than 3m.

[0011] The technical effects and advantages provided by this utility model in the above technical solution are as follows: This invention enhances the overall stability of porous brick walls by pre-embedding concrete blocks within them. U-shaped threaded rods are also embedded within these blocks, and a new support system is constructed using horizontal and vertical angle steel secondary joists. This significantly reduces the need for main joists, effectively lightening the load on the wall and lowering construction difficulty and cost, eliminating the need for on-site welding and assembly of galvanized rectangular tube main joists. Through the rational arrangement of U-shaped threaded rods, horizontal angle steel secondary joists, and vertical angle steel secondary joists, the use of main materials is reduced without compromising project quality, thus improving construction efficiency, shortening the construction period, and lowering project costs.

[0015] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0016] like Figure 1-3 As shown, a perforated brick wall structure without main keel support, a dry-hanging brick wall, includes a perforated brick wall 1, on which concrete embedded blocks 2 are arranged at intervals in the horizontal and vertical directions. The concrete embedded blocks 2 are poured simultaneously during the construction of the perforated brick wall 1, and their positions are determined according to the size and layout of the bricks. The horizontal center-to-center distance between the horizontally spaced concrete embedded blocks 2 is no greater than 650mm, and the edge of the vertically spaced concrete embedded blocks 2 is no less than 150mm from the top and bottom edges of the tiles to ensure uniform support and not affect the installation of the bricks.

[0017] Preferably, the concrete embedded block 2 is cast from commercial concrete with a strength of not less than C25, and is rectangular in shape, with dimensions determined according to design requirements. A U-shaped screw 3 is pre-embedded within the concrete embedded block 2. The U-shaped screw 3 is made of galvanized carbon steel, with a thread length of 80mm, a thread diameter of 8mm, and an inner diameter of 114mm for both screws. The screw protrudes at least 50mm from the side of the concrete embedded block 2. During pre-embedding, the open end of the U-shaped screw 3 faces outwards from the wall for easy subsequent connection.

[0018] Furthermore, a horizontal angle steel secondary keel 4 is connected to the U-shaped screw 3, and the horizontal angle steel secondary keel 4 is fixed to the U-shaped screw 3 with nuts. The ends of the horizontal angle steel secondary keel 4 are connected to vertical angle steel secondary keels 5, and the connection method can be welding or bolt fixing. The horizontal angle steel secondary keel 4 and the vertical angle steel secondary keel 5 are made of galvanized angle steel, with specifications of 50mm×50mm×4mm. The length of the horizontal angle steel secondary keel 4 is no more than 3m. Multiple horizontal angle steel secondary keels 4 are connected to the vertical angle steel secondary keels 5 to form an integral frame, forming a stable support system.

[0019] An L-shaped dry-hanging fastener 6 is connected to the horizontal angle steel secondary keel 4. The L-shaped dry-hanging fastener 6 is fixed to the horizontal angle steel secondary keel 4 by bolts or welding. The L-shaped dry-hanging fastener 6 is used for dry-hanging wall tiles. The back of the wall tile is connected to the L-shaped dry-hanging fastener 6 through a groove or back strip to fix the wall panel.

[0020] During construction, a detailed layout drawing of the dry-hanging wall bricks must be completed before the start of masonry construction. Based on the layout of the wall bricks in the detailed drawing, concrete embedded block 2 is placed. M8 U-shaped screws 3 are embedded inside the concrete embedded block 2. The screws are made of galvanized carbon steel, with a thread length of 80mm, a thread diameter of M8, and an inner diameter of 114mm for both screws. The screws protrude no less than 50mm from the side of the embedded block masonry. The concrete embedded block 2 is cast using commercial concrete with a strength of no less than C25. After the concrete embedded block 2 is formed, it is cured with normal moisture for 7 working days before masonry installation can be carried out. To ensure the firmness and reliability of the dry-hanging wall tiles, the horizontal center-to-center spacing of the concrete embedded blocks 2 should not exceed 650mm; the vertical spacing can be determined according to the size of the dry-hanging wall tiles. Generally, for wall tiles ≥600mm×600mm, at least four dry-hanging points must be selected for fixing the wall tiles, ensuring a firm wall and preventing tiles from falling off. The concrete embedded blocks 2 are installed according to the layout drawing. After the wall is built and reaches the required strength, the horizontal angle steel secondary keel 4 can be installed. To ensure the firmness and stability of the dry-hanging system, the maximum installation length of the horizontal angle steel secondary keel 4 is 3m (i.e., it must be broken every 3m). Vertical angle steel secondary keels 5 are installed at both ends of each horizontal angle steel secondary keel 4 to ensure the integrity of the dry-hanging system within a horizontal 3m range. The above-mentioned horizontal and vertical galvanized angle steel secondary keels are fixed with bolts. Finally, the back strip dry-hanging wall tiles are installed on the angle steel secondary keels according to the specifications and design drawings.

[0021] This utility model has a simple structure and is easy to construct. It avoids the use of a main keel, reducing costs and construction difficulty. At the same time, the embedded parts and secondary keel frame ensure the stability and safety of dry-hanging wall bricks. It is suitable for various scenarios such as residential and commercial buildings.

[0022] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
