Description

Technical Field

[0001] This utility model relates to the field of prefabricated railing technology, specifically a prefabricated railing. Background Technology

[0002] Traditional railings often employ welded or monolithic cast-in-place structures, which present several drawbacks: welded railings require on-site welding, resulting in low construction efficiency, and the welding quality is heavily influenced by the worker's skill level, easily leading to safety hazards such as weld cracking. Furthermore, on-site welding generates dust and noise pollution. Monolithic cast-in-place railings have long construction cycles and cannot be disassembled or adjusted after completion. If repairs or modifications are needed later, the entire structure must be removed, resulting in material waste and increased construction costs. In addition, the connection methods for the various components of traditional railings are complex, requiring multiple specialized tools during installation, making the operation difficult and hindering rapid construction.

[0026] Figures 1-4 The diagram shown is a structural schematic of the first embodiment of the prefabricated railing of this utility model. Please refer to [link / reference]. Figures 1-4 The prefabricated railing of this embodiment includes a main pole body 100 as its main body.

[0027] The inner wall of the main rod 100 is provided with a plug groove 110, the top of the main rod 100 is provided with a plug block 120, a crossbar 150 is installed in the plug groove 110, a secondary rod 170 is installed on the crossbar 150, an end cap 180 is installed on the top of the plug block 120, sealing plugs 190 are installed at both ends of the end cap 180, and a fixing rod 200 is installed on the inner side of the sealing plug 190.

[0028] The main rod 100 has the following structure: The inner side wall of the main rod 100 is provided with a plug groove 110 that is adapted to the crossbar 150 for installation at the end of the crossbar 150; The top of the main rod 100 is integrally formed with a plug block 120, and the plug block 120 is provided with multiple limiting holes 130 along the vertical direction. The limiting holes 130 are used to cooperate with the fixing rod 200 to fix the end cap 180; The center of the main rod 100 is provided with a guide hole 140 along the vertical direction. The guide hole 140 passes through the upper and lower ends of the main rod 100 for the insertion and installation of the plug rod.

[0029] Connection between the crossbar 150 and the main rod 100: Connecting blocks 151 are integrally formed at both ends of the crossbar 150. The size of the connecting blocks 151 is adapted to the insertion slots 110 of the main rod 100. The connecting blocks 151 are provided with fixing holes 152 that are coaxial with the guide holes 140. The crossbar 150 is inserted into the insertion slots 110 of the main rod 100 through the connecting blocks 151 at both ends, and the insertion rod passes through the guide holes 140 of the main rod 100 and is inserted into the fixing holes 152 of the connecting blocks 151, so as to achieve a firm connection between the crossbar 150 and the main rod 100.

[0030] Connection between the secondary rod 170 and the crossbar 150: The top of the crossbar 150 has multiple slots 153 along its length. The bottom of the secondary rod 170 is inserted into the slots 153 of the crossbar 150 to achieve initial positioning of the secondary rod 170 and the crossbar 150. The top of the secondary rod 170 extends into the inner cavity of the end cap 180 to further improve the installation stability of the secondary rod 170.

[0031] Connection between end cap 180 and main rod 100: End cap 180 covers the plug block 120 on the top of main rod 100. Sealing plugs 190 are installed at both ends of end cap 180. Sealing plugs 190 are made of elastic rubber and are used to seal the gap between end cap 180 and main rod 100, so as to prevent dust and water. A fixing rod 200 is fixedly connected to the inner side of the sealing plug 190. The number of fixing rods 200 is the same as the number of limiting holes 130 on plug block 120. The end of fixing rod 200 away from sealing plug 190 is inserted into the limiting hole 130, so as to realize the detachable fixing of end cap 180 and main rod 100.

[0032] Main rod 100: Made of stainless steel, with a rectangular cross-section. The length is set according to the installation height (e.g., 1.1-1.2m). The width of the insertion slot 110 is adapted to the thickness of the connecting block 151 of the crossbar 150 (e.g., 10-15mm). The diameter of the guide hole 140 is adapted to the diameter of the insertion rod (e.g., 8-12mm). The height of the insertion block 120 is 30-50mm. There are 2-4 limiting holes 130, which are evenly distributed on the insertion block 120.

[0033] Horizontal bar 150: Made of stainless steel, with a rectangular cross-section, and its length is set according to the span of the railing (e.g., 1.5-3m). The length of the connecting block 151 is 50-80mm, and the diameter of the fixing hole 152 is the same as that of the guide hole 140.

[0034] Sub-rod 170: Made of stainless steel, it is a round rod structure with a diameter of 16-20mm. The length is set according to the distance between the main rod 100 and the end cap 180 (e.g., 800-1000mm), and the number is evenly distributed according to the length of the crossbar 150 (e.g., one every 300-400mm).

[0035] End cap 180: Made of aluminum alloy, with a U-shaped cross section. The internal cavity size is adapted to the top of the secondary rod 170, and the length is the same as the length of the crossbar 150. The sealing plug 190 is made of silicone rubber, and the fixing rod 200 is made of stainless steel with a diameter of 6-8mm and a length adapted to the depth of the limiting hole 130 (e.g., 20-30mm).

[0036] Connecting rod: Made of stainless steel, with a diameter that matches the guide hole 140 and a length greater than the height of the main rod 100, ensuring that both ends can be fixed after insertion.

[0037] The inner wall of the main rod 100 insertion groove 110 and the outer wall of the crossbar 150 connecting block 151 are both smoothed to reduce frictional resistance during installation. At the same time, rust-preventive lubricant is applied to the contact surface to improve the tightness of the connection and the rust prevention effect.

[0038] The depth to which the secondary rod 170 is inserted into the slot 153 of the crossbar 150 is not less than 50mm to ensure connection stability; the inner cavity of the end cap 180 and the top of the secondary rod 170 are clearance fit for easy installation and disassembly.

[0039] The sealing plug 190 and the end cap 180 are fitted with an interference fit to ensure that they are not easily detached after installation; the fixing rod 200 and the sealing plug 190 are fixed with a vulcanization bonding process, and the connection is firm and reliable.

[0040] Combination Figures 1-3 The working principle of this prefabricated railing is as follows:

[0041] First, determine the installation position of the main pole 100 according to the installation requirements, and fix it on the preset foundation (such as the ground, the edge of the balcony, etc.).

[0042] Take the crossbar 150, align the connecting blocks 151 at both ends with the insertion slots 110 of the main rod body 100, and slowly insert them until the fixing holes 152 of the connecting blocks 151 are coaxially aligned with the guide holes 140 of the main rod body 100.

[0043] Insert the plug rod into the guide hole 140 at the bottom of the main rod 100, and pass it through the fixing hole 152 of the main rod 100 and the crossbar 150 connecting block 151 in sequence to complete the connection between the crossbar 150 and the main rod 100.

[0044] Insert the secondary rods 170 one by one into the slots 153 at the top of the crossbar 150, ensuring that the bottom of the secondary rods 170 is fully embedded in the insertion slots 110 and that the secondary rods 170 remain vertical.

[0045] The end cap 180 is placed on the insertion block 120 of the main rod 100, so that the top of the secondary rod 170 is inserted into the inner cavity of the end cap 180.

[0046] Press the sealing plugs 190 at both ends of the end cap 180 so that the fixing rod 200 inside the sealing plug 190 is inserted into the limiting hole 130 of the plug block 120, thus fixing the end cap 180. At this time, the sealing plug 190 is tightly attached to the outer wall of the main rod body 100 to achieve a seal.
