Description

Technical Field

[0001] This invention belongs to the field of architectural decoration technology, and in particular relates to a dry-hanging stone prefabricated design structure for the exterior facade of an ancient city wall. Background Technology

[0002] City walls, ancient military defense facilities, are military defense lines composed of walls and other auxiliary military facilities. Ancient city walls can reflect the cultural connotation of ancient architecture. Dry-hanging stone is made from raw stone blocks, processed into shape, and then carved and shaped to showcase the overall projection effect of the ancient city wall. The stone itself has good wear resistance, weather resistance and corrosion resistance, and can also be processed into various shapes. The external surface decoration effect is good, which can well present the form and connotation of the ancient city wall.

[0003] Chinese patent (CN201510432837.8) discloses a method for treating the surface of an antique Ming Dynasty city wall, including the following steps: (1) laying base bricks; (2) carving wall seams and large textures; (3) creating inscriptions; (4) coloring and aging; (5) detail treatment.

[0004] Chinese Patent (CN201820534385.3) discloses an imitation ancient city wall. The invention includes a frame and a wall. The frame includes frame columns and frame beams; the wall includes an inner wall layer and an outer wall layer. The inner wall layer includes a first inner wall layer at the top, constructed of shale red bricks, and a second inner wall layer at the bottom, also constructed of shale red bricks. The outer wall layer includes a first outer wall layer at the top, constructed of city bricks, and a second outer wall layer at the bottom, constructed of hewn stone. A first ring beam is also provided between the first and second inner wall layers. The first ring beam is located inside the frame beam and extends into the interior of the first outer wall layer. Tie bars are provided between the first outer wall layer and the first inner wall layer.

[0005] Chinese Patent (CN202120897875.1) discloses a connection structure for dry-hanging stone cladding on building facades, belonging to the field of stone curtain wall technology. The connection structure includes a horizontal keel, a fixing seat welded to the horizontal keel, an angle iron slidably connected to the top surface of the fixing seat, a fixing mechanism on the angle iron, a connecting plate at the upper right end of the angle iron, a connecting hole on the lower right wall of the connecting plate, an adjusting plate inside the upper part of the connecting plate, and buffer pads fixedly connected to the inner side of the upper part and the lower left wall of the connecting plate.

[0006] Currently, the exterior of the ancient city wall is constructed using aged bricks similar to those used in the city wall. This requires a large amount of building materials and the installation process is quite complex, relying heavily on the expertise of the construction workers. In addition, using dry-hanging stone for the exterior requires the continuous connection and installation of the back reinforcement and the keel during construction, making the installation operation inconvenient. Summary of the Invention

[0007] The purpose of this invention is to solve the problems of high installation difficulty, low construction efficiency and poor installation flexibility caused by the traditional use of brick stacking or dry hanging installation with back reinforcement on the exterior facade of ancient city walls. Therefore, this invention proposes a dry hanging stone prefabricated design structure for the exterior facade of ancient city walls.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a dry-hanging stone prefabricated design structure for the exterior facade of an ancient city wall, comprising:

[0009] Multiple main keels are embedded in the sloping wall surface of the city wall base. The multiple main keels are parallel to each other. The upper end of the main keel extends to the top of the city wall base, and the lower end of the main keel is buried in the ground base.

[0010] Multiple horizontal grooves are formed on the inclined wall surface. The horizontal grooves are arranged horizontally, and the multiple horizontal grooves are evenly arranged at equal intervals along the direction of the main keel.

[0011] Multiple baseboards are laid on the sloping wall surface, and the baseboards are inserted into the horizontal grooves. The multiple baseboards are arranged in a rectangular array, and adjacent baseboards are bonded together.

[0012] Multiple fixing rods are located within the transverse groove. The fixing rods are inserted into the base plate from one side of the base plate and pass through the main keel.

[0013] Multiple decorative panels are laid on the base plate, and each decorative panel corresponds to one of the base plates.

[0014] As a further description of the above technical solution:

[0015] The surface of the main keel coincides with the sloping wall surface.

[0016] As a further description of the above technical solution:

[0017] The back of the base plate is provided with multiple positioning protrusions, and the positioning protrusions have a clearance in the middle. The positioning protrusions are engaged in the transverse grooves, and the main keel is engaged in the clearance.

[0018] As a further description of the above technical solution:

[0019] The positioning boss has a first positioning hole on its side, and the main keel has multiple second positioning holes. The fixing rod is inserted into the first positioning hole from one side of the positioning boss, and the fixing rod passes through the second positioning hole.

[0020] As a further description of the above technical solution:

[0021] One end of the fixing rod is provided with a rubber pad, which abuts against the side of the positioning boss, protrudes from the side of the base plate, and abuts against the positioning boss on another base plate.

[0022] As a further description of the above technical solution:

[0023] The fixing rod passes through the positioning boss, and the end of one fixing rod abuts against the rubber pad on the adjacent fixing rod.

[0024] As a further description of the above technical solution:

[0025] The first positioning hole and the second positioning hole have the same axis and the same diameter.

[0026] As a further description of the above technical solution:

[0027] At least two fixing rods are inserted into the base plate.

[0028] As a further description of the above technical solution:

[0029] The two adjacent decorative panels are bonded together.

[0030] As a further description of the above technical solution:

[0031] The decorative panel is an imitation stone panel.

[0032] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0033] 1. In this invention, a main keel is embedded in the sloping wall surface and buried in the ground base layer to form a high-strength structural base layer. The base plate is then inserted into the horizontal groove, which initially restricts the freedom of the base plate. A fixing rod is then inserted into the base plate from one side of the horizontal groove, passing through the main keel, which fully restricts the freedom of the base plate. This eliminates the need for professional construction work, making the installation simple and convenient, greatly reducing the construction difficulty and improving the construction efficiency.

[0034] 2. In this invention, by inserting the positioning boss into any horizontal groove and the clearance groove into the main keel, the baseboard can be installed at any position on the sloping wall, which greatly improves the flexibility of the installation operation.

[0046] Please see Figure 1-8 This invention provides a technical solution: a prefabricated design structure for dry-hanging stone cladding on the exterior facade of an ancient city wall, comprising:

[0047] Multiple main keels 1 are embedded in the inclined wall surface 3 of the city wall base 2. The multiple main keels 1 are parallel to each other. The upper end of the main keel 1 extends to the top of the city wall base 2, and the lower end of the main keel 1 is buried in the ground base 4.

[0048] Multiple horizontal grooves 5 are formed on the inclined wall surface 3. The horizontal grooves 5 are arranged horizontally, and the multiple horizontal grooves 5 are evenly arranged at equal distances along the direction of the main keel 1.

[0049] Multiple baseboards 6 are laid on the inclined wall surface 3, and the baseboards 6 are inserted into the transverse grooves 5. The multiple baseboards 6 are arranged in a rectangular array, and adjacent baseboards 6 are bonded together.

[0050] Multiple fixing rods 7 are located in the transverse groove 5. The fixing rods 7 are inserted into the base plate 6 from one side of the base plate 6 and pass through the main keel 1.

[0051] Multiple decorative panels 8 are laid on the base plate 6, and the decorative panels 8 correspond one-to-one with the base plate 6;

[0052] The surface of the main keel 1 coincides with the inclined wall surface 3;

[0053] The back of the base plate 6 is provided with multiple positioning protrusions 13, and the center of the positioning protrusions 13 is provided with a clearance 9. The positioning protrusions 13 are inserted into the transverse groove 5, and the main keel 1 is inserted into the clearance 9.

[0054] The positioning boss 13 has a first positioning hole 10 on its side, and the main keel 1 has a plurality of second positioning holes 11. The fixing rod 7 is inserted into the first positioning hole 10 from one side of the positioning boss 13, and the fixing rod 7 passes through the second positioning hole 11. By inserting the fixing rod 7 into the first positioning hole 10 and the second positioning hole 11, the mutual constraint between the positioning boss 13 and the main keel 1 can be established, thereby facilitating the rapid installation of the base plate 6.

[0055] One end of the fixing rod 7 is provided with a rubber pad 12, which abuts against the side of the positioning boss 13. The rubber pad 12 protrudes from the side of the base plate 6 and abuts against the positioning boss 13 on another base plate 6. The fixing rod 7 passes through the positioning boss 13, and the end of one fixing rod 7 abuts against the rubber pad 12 on the adjacent fixing rod 7 to prevent the fixing rod 7 from moving within the first positioning hole 10 or the second positioning hole 11, thus ensuring the stability of the installation structure.

[0056] The first positioning hole 10 and the second positioning hole 11 have the same axis and the same diameter, which ensures the stability of the installation structure;

[0057] At least two fixing rods 7 are inserted into the base plate 6 to ensure the stability of the installation structure;

[0058] The two adjacent decorative panels 8 are bonded together to ensure the aesthetic effect of the decoration and also to ensure the airtightness of the installation structure;

[0059] The decorative panel 8 is an imitation stone panel, ensuring that the decorative effect maintains the appearance of the ancient city wall facade.

[0060] Working principle: First, during installation, a groove suitable for installing the main keel 1 is cut into the sloping wall surface 3, and a deep hole is dug in the ground base 4. The main keel 1 is installed in the groove, keeping the surface of the main keel 1 aligned with the sloping wall surface 3, so that the upper end of the main keel 1 coincides with the top of the base 2 of the wall, and the lower end of the main keel 1 extends into the deep hole. After filling the deep hole, the lower end of the main keel 1 is buried in the ground base 4. Multiple horizontal grooves 5 are cut into the sloping wall surface 3. The horizontal grooves 5 are arranged horizontally, and multiple sets of horizontal grooves 5 are evenly arranged at equal intervals along the direction of the main keel 1, completing the installation of the base structure. Next, decorative panels 8 are pre-laid on the base board 6, and multiple decorative panels 8 are installed in sequence. Then, the positioning bosses 13 on the base board 6 are inserted into the horizontal grooves 5, and the main keel 1 is installed. The main keel 1 is inserted into the clearance 9. The transverse groove 5 limits the vertical sliding of the base plate 6, and the main keel 1 limits the horizontal sliding of the base plate 6. At this time, the fixing rod 7 is inserted into the first positioning hole 10 from one side of the positioning boss 13. Then the fixing rod 7 passes through the second positioning hole 11 until the rubber pad 12 at the end of the fixing rod 7 abuts against the side of the positioning boss 13. The same base plate 6 is connected to the main keel 1 through at least two fixing rods 7. Finally, multiple base plates 6 are installed in sequence to keep the two adjacent base plates 6 in contact. The decorative panels 8 laid on the base plates 6 are also in contact accordingly. At this time, the end of one fixing rod 7 abuts against the rubber pad 12 on the other fixing rod 7 next to it to prevent the fixing rod 7 from moving in the first positioning hole 10 or the second positioning hole 11.

[0061] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
