Description

Technical Field

[0001] This invention belongs to the field of ceramic brick guardrail installation technology, and particularly relates to a construction method for a cantilevered ceramic brick guardrail. Background Technology

[0002] Guardrails are architectural structures used for safety protection and decoration, enclosing and protecting the edges of areas such as balconies, staircases, and corridors to prevent accidental falls. Currently, the mainstream guardrail construction includes three types: traditional masonry guardrails, metal frame + infill panel guardrails, and precast concrete siding guardrails. While all achieve their protective function, they all suffer from the following problems: Traditional masonry railings: are constructed entirely of bricks or concrete, resulting in a heavy structure that requires foundation support. Their excessive weight places high demands on the building structure's load-bearing capacity. They also have long construction cycles, require on-site wet work, and are not environmentally friendly. Furthermore, their designs are limited and fail to achieve the light and airy aesthetics sought after in modern architecture.

[0003] Metal frame + infill panel railing: It uses steel / aluminum alloy as the skeleton and fills it with glass, metal or wood panels. It is common in modern buildings, but the metal skeleton is prone to corrosion (especially in coastal or high humidity environments) and has high maintenance costs; rigid connection leads to stress concentration and welds or bolts are prone to loosening after long-term use; the infill panel relies on external fasteners and visually presents redundant support structure.

[0004] Precast concrete hanging panel railings: Concrete panels are suspended from the main structure through embedded parts, which reduces some weight, but the panels are thick (usually ≥80mm), and the bending moment at the root is significant when cantilevered; the surface requires an additional decorative layer (such as paint or veneer), resulting in high overall cost.

[0005] It is evident that existing guardrail structures generally face the contradiction between "structural redundancy" and "aesthetic simplicity." To address these technical issues, this invention designs a cantilevered guardrail with a ceramic brick panel. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the present invention provides a construction method for a cantilevered guardrail with ceramic brick panel, which effectively solves the problems existing in the traditional guardrail construction.

[0007] The present invention achieves the above-mentioned technical objectives through the following technical means.

[0008] A construction method for a cantilevered railing with ceramic brick panels includes the following steps: Step 1: Install multiple adapters on the main structure at the installation location of the guardrail. All adapters are welded and fixed to the embedded parts pre-embedded in the main structure. Step 2: Install the uprights on the adapter, and then install the horizontal frame on the uprights; Step 3: Install ceramic bricks and steel pipes on the horizontal frame; Step 4: Fluorocarbon coating; Step 5: Install the columns and some of the external decorative profiles on the horizontal frame; Step 6: Hang ceramic bricks on the steel pipe; Step 7: Install the outer decorative profiles on the top horizontal frame of the guardrail.

[0009] Furthermore, in step 2, during the installation of the columns, each column is welded and fixed to the corresponding adapter. The column installation proceeds from one side to the other, and the verticality and spatial positioning of the columns are controlled during the installation. The horizontal frame consists of a lower layer of galvanized steel pipes, a middle layer of steel plates, and an upper layer of steel plates. The lower layer of galvanized steel pipes is welded to the bottom of the columns, the middle layer of steel plates is welded to the middle of the columns, and the upper layer of steel plates is welded to the top of the columns. The middle layer of steel plates serves to seal the gap between the terracotta bricks and the floor slab, preventing people from stepping into the gap. The lower layer of galvanized steel pipes, the middle layer of steel plates, and the upper layer of steel plates are all arranged along the length, connecting multiple columns in a row.

[0010] Furthermore, the specific process of step 3 is as follows: Position the ceramic brick steel pipe by marking out the location on the lower galvanized steel pipe. Cut the ceramic brick steel pipe to the required length according to the drawing in advance. Then, weld the ceramic brick steel pipe vertically to the lower galvanized steel pipe according to the marked position. The distance between the top of the ceramic brick steel pipe and the lower surface of the upper steel plate should be greater than or equal to the height of a ceramic brick.

[0011] Furthermore, the specific process of step 6 is as follows: Ceramic bricks with mounting holes are sequentially placed on the ceramic brick steel pipe from bottom to top, with spacers separating adjacent ceramic bricks. When installing the top ceramic brick, the installer first places the ceramic brick and temporarily holds it by hand to ensure that the center of the hole on the ceramic brick is on the same vertical line as the center of the hole on the ceramic brick below it. Then, a long pin is passed through the upper steel plate, the top ceramic brick, and the spacers in sequence until the long pin is driven into the limiting block inside the ceramic brick steel pipe, thus fixing the entire ceramic brick steel pipe.

[0012] Furthermore, the specific process of step 7 is as follows: Place the outer decorative profile on the upper steel plate, and use spacers and rubber sheets to separate the outer decorative profile from the upper steel plate. Then, use bolts to fix the outer decorative profile to the upper steel plate from below, and install the decorative profile cover below to conceal the bolts fixing the outer decorative profile and seal the outer decorative profile. Finally, apply sealant to the gap between the outer decorative profile and the upper steel plate to seal it.

[0013] Furthermore, the specific process of step 5 is as follows: First, install the outer decorative profiles of the columns, then install the lower galvanized steel pipes and the middle steel plate of the horizontal frame with their outer decorative profiles; when installing the outer decorative profiles, use flexible gaskets to separate the parts in contact with the steel to prevent bimetallic corrosion.

[0014] Furthermore, in step 4, the adapter, column, ceramic brick steel pipe, and upper steel plate are treated with fluorocarbon spraying, and the same color is ensured; the raw materials for fluorocarbon spraying are epoxy zinc-rich primer + epoxy micaceous iron oxide intermediate paint + fluorocarbon topcoat.

[0015] The present invention has the following beneficial effects: Beautiful and grand: The appearance of terracotta brick railings is diverse and colorful, which can meet the style and needs of different buildings and make the overall building more beautiful and grand; the use of terracotta brick material gives the railings a different visual effect and meets the needs of personalized design.

[0016] The structure of the terracotta brick railing: This railing system is composed of a steel frame and terracotta brick materials, forming a safe and stable railing system. It is also lightweight and does not have high load requirements on the building structure. The thickness of the plates is not large, and the bending moment at the root is not large when cantilevered.

[0017] Easy to install: The ceramic brick railing of this invention can be directly installed on the building wall without the need for a concrete foundation. The posts and railing frame and other components can be prefabricated. On-site construction only requires welding with the adapter and then hanging the ceramic bricks. Therefore, the installation process is convenient and quick. At the same time, it can also be easily disassembled and replaced after installation, and the construction cycle is shorter.

[0018] Environmentally friendly and green: Ceramic bricks are an environmentally friendly and green decorative material made from natural minerals and inorganic materials. They do not contain any harmful substances or chemical additives and do not pollute the human body or the environment.

[0019] Excellent corrosion resistance: Ceramic bricks are made of high-strength inorganic materials, which are not easily corroded and can maintain their appearance, durability and stability for a long time.

[0020] Good aesthetics: The steel frame is covered with aluminum alloy decorative profiles, and the fasteners are all hidden. There is no redundant support structure in the visual appearance, which makes it more aesthetically pleasing.

[0021] This invention is applicable to the installation of various types of guardrails, especially those requiring diverse, aesthetically pleasing, and environmentally friendly features. Through research and application of terracotta brick guardrails and their construction methods, a new, environmentally friendly, and diversified guardrail system has been provided to my country's construction industry.

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but the scope of protection of the present invention is not limited thereto.

[0025] The construction method of the cantilevered guardrail with ceramic brick panel according to the present invention includes the following process: Step 1: Install adapter 1; Reference Figure 1 As shown, the adapter 1 is preferably made of galvanized steel pipe with a cross-sectional size of 100×50×5mm. The length of the adapter 1 is determined according to the drawings. One end of the adapter 1 is welded and fixed to the embedded part 2 on the building structure.

[0026] Step 2: Install the guardrail frame, which includes the uprights 3 and the horizontal frame 4; Reference Figure 1 , 2 As shown in Figure 4, each post 3 is welded and fixed to the other end of the corresponding adapter 1. The adapter 1 is a load-bearing component that can transfer the weight of the entire guardrail to the main structure. The post 3 is installed from one side to the other, and the verticality and spatial positioning of the post 3 are controlled during the installation.

[0027] After the posts 3 are installed, the horizontal frame 4 of the guardrail is installed. The horizontal frame 4 includes a lower galvanized steel pipe 401, a middle steel plate 402, and an upper steel plate 403. The lower galvanized steel pipe 401 is welded and fixed to the bottom of the post 3, the middle steel plate 402 is welded and fixed to the middle of the post 3, and the upper steel plate 403 is welded and fixed to the top of the post 3. The middle steel plate 402 serves as a seal between the terracotta bricks 7 and the floor slab, which can prevent people from stepping into gaps and can also stabilize the entire guardrail system. The lower galvanized steel pipe 401, the middle steel plate 402, and the upper steel plate 403 are all arranged along the length of the post 3, which together connect multiple posts 3 in a row.

[0028] In this embodiment, preferably, the lower galvanized steel pipe 401 has a cross-sectional size of 30×240×4mm, the middle steel plate 402 has a size of 95×20mm, and the upper steel plate 403 has a thickness of 12mm; the column 3 uses a galvanized steel pipe with a cross-sectional size of 100×50×5mm.

[0029] During the above installation process, symmetrical welding should be used to reduce deformation caused by welding. After welding is completed, after the weld quality is inspected and found to be qualified, all weld points and welds should be free of welding slag and treated with two layers of rust prevention.

[0030] Step 3: Installation of ceramic bricks and steel pipes 5; Reference Figure 1 , 3 As shown in Figure 4, the position of the ceramic brick steel pipe 5 is determined by positioning and marking lines on the lower galvanized steel pipe 401. The ceramic brick steel pipe 5 is cut into the required length according to the drawing in advance. Then, the ceramic brick steel pipe 5 is vertically welded to the lower galvanized steel pipe 401 according to the layout position. The distance between the top of the ceramic brick steel pipe 5 and the lower surface of the upper steel plate 403 should be greater than or equal to the height of a ceramic brick 7, so that the top ceramic brick 7 can be freely strung and inserted during subsequent installation. The ceramic brick steel pipe 5 is preferably a round steel pipe with an outer diameter of 30mm and a wall thickness of 4mm.

[0031] Step 4: Fluorocarbon coating; The adapter 1, column 3, ceramic brick steel pipe 5, and upper steel plate 403 are treated with fluorocarbon spraying to ensure the same color; the raw materials for fluorocarbon spraying are epoxy zinc-rich primer + epoxy micaceous iron oxide intermediate paint + fluorocarbon topcoat.

[0032] Step 5: Install the outer decorative profiles 6 on the columns 3 and the horizontal frame 4; First, install the outer decorative profile 6 of the column 3, and then install the outer decorative profile 6 of the lower galvanized steel pipe 401 and the middle steel plate 402 of the horizontal frame 4. When installing the outer decorative profile 6, use flexible gaskets to separate the parts in contact with the steel to prevent bimetallic corrosion. The use of the outer decorative profile 6 can ensure the aesthetic appearance of the overall guardrail.

[0033] Step 6: Hang the ceramic bricks in a string; Reference Figure 1 , 3As shown in Figure 4, ceramic bricks 7 with installation holes are strung on the ceramic brick steel pipe 5. The ceramic bricks 7 are installed from bottom to top, and are inserted into the ceramic brick steel pipe 5 one by one. The upper and lower adjacent ceramic bricks 7 are separated by a spacer block 9 (the spacer block 9 also has holes and is also fitted onto the ceramic brick steel pipe 5). The ceramic bricks 7 should be placed carefully and slowly to avoid damage. When installing the top ceramic brick 7, the installer first places the ceramic brick 7 and temporarily holds it with his hand to ensure that the center of the hole on the ceramic brick 7 is on the same vertical line as the center of the hole on the ceramic brick 7 below it. Then, a long pin 8 is inserted through the upper steel plate 403 (which has holes pre-drilled), the top ceramic brick 7, and the spacer block 9 in sequence until the long pin 8 is driven into the limiting block inside the ceramic brick steel pipe 5 (the limiting block is a circular steel plate structure with a round hole in the center inside the ceramic brick steel pipe 5, used to limit the movement of the long pin 8), so that the entire ceramic brick steel pipe 5 is fixed and the strung ceramic bricks 7 do not tip over.

[0034] In this embodiment, preferably, the ceramic brick 7 has a size of 240×115×50, and two holes with a diameter of 32mm are opened on the ceramic brick 7.

[0035] Step 7: Install the outer decorative profile 6 on the handrail (i.e., the upper steel plate 403); Reference Figure 2 , 4 Place the outer decorative profile 6 on the upper steel plate 403, and use a spacer 9 and rubber sheet 10 to separate the outer decorative profile 6 from the upper steel plate 403. Then use bolts 11 to fix the outer decorative profile 6 to the upper steel plate 403 from below, and install the decorative profile cover 12 below to conceal the bolts 11 that fix the outer decorative profile 6 and seal the outer decorative profile 6. Then apply sealant 13 to the gap between the outer decorative profile 6 and the upper steel plate 403 to seal it.

[0036] The embodiments described above are preferred embodiments of the present invention, but the present invention is not limited to the above embodiments. Any obvious improvements, substitutions or modifications that can be made by those skilled in the art without departing from the essence of the present invention shall fall within the protection scope of the present invention.
